Background Art

In the passive optical network system, passive optical network equipment can be divided into the following modes according to different working mechanisms: Ethernet-based passive optical network equipment (Ethernet Passive Optical Network, referred to as EPON), 10G Ethernet-based passive optical network equipment (10G Ethernet Passive Optical Network, referred to as 10G EPON), Gigabit passive optical network equipment (Gigabit-capable Passive Optical Network, referred to as GPON), 10G passive optical network equipment (10-Gigabit-capable Passive Optical Networks, referred to as XGPON), 10G symmetric passive optical network equipment (10G symmetric passive optical network, referred to as XGPON), 10G symmetric passive optical network equipment (10G symmetric passive optical network, referred to as XGPON), 10G symmetric passive optical network equipment (10G symmetric passive optical network, referred to as XGPON), 10G symmetric passive optical network equipment (10G symmetric passive optical network, referred to as XGPON), 10G symmetric passive optical network equipment (10G symmetric passive optical network, referred to as XGPON), 10G symmetric passive optical network equipment (10G symmetric passive optical network, referred to as XGPON), 10G symmetric passive optical network equipment (10G symmetric passive optical network, referred to as ... 0-Gigabit-capable Symmetric Passive Optical Networks, abbreviated as XGSPON), 40G passive optical network equipment (40-Gigabit-capable Passive Optical Networks, abbreviated as NGPON2), and 50G passive optical network equipment (50-Gigabit-capable Passive Optical Network, abbreviated as 50G PON) and 200G next generation high-density point-to-multipoint passive optical network (200Gigabit-capable Virtualized Hybrid Service Provider, abbreviated as 200G PON (VHSP)) which are being researched at the moment. These passive optical network system architectures generally include Optical Line Terminal, abbreviated as OLT), Optical Distribution Network and Optical Network Unit (ONU). With the continuous development of optical networks, fiber to the home (FTTH) has been fully rolled out, and its terminal product ONU has also been widely used. However, due to the limited transmission rate of network cables and the weakening of Wi-Fi signals by building load-bearing walls, the signal quality and network speed of traditional networking solutions are seriously attenuated, and it is impossible to achieve high-speed Wi-Fi network coverage throughout the house. The FTTR networking solution adopts a mode in which a single master gateway matches one or more slave gateways. The master and slave gateways are connected by optical fiber, which has stronger data transmission and anti-interference capabilities and longer life, achieving true high-speed Wi-Fi coverage without blind spots throughout the house.

In the passive optical network system, the upstream and downstream wavelengths and rates of different modes of passive optical network (PON) access technology are different. The specific differences are shown in Table 1 below:

Table 1

Exemplarily, FIG1 is a schematic diagram of wavelengths of PON access technologies in different modes.

As shown in Figure 1, GPON and EPON ONUs operate in the upstream 1310nm and downstream 1490nm bands; XEPON (symmetric and asymmetric), XGPON and XGSPON ONUs operate in the upstream 1270nm and downstream 1577nm bands; NGPON2ONUs operate in the upstream 1532.68~1538.19nm and downstream 1596.34~1602.31nm bands (up to 8 bands for upstream and downstream); 50G PON operates in the upstream λ ₁ nm and downstream β ₁ nm bands; 200G PON operates in the upstream λ ₂ nm and downstream β ₂ nm bands.

The cost of the main gateway equipment for FTTR to complete the networking is relatively high. The existing related technologies do not provide an effective solution for the FTTR main gateway and slave gateway to be widely compatible with multiple PON modes running in the existing network and to achieve automatic or active switching of multiple PON modes.

In the related art, in actual FTTR applications, the FTTR master gateway and the slave gateway cannot implement the switching of multiple PON modes, and no effective solution has been proposed yet.

Therefore, it is necessary to improve the related technology to overcome the above-mentioned defects in the related technology.

FIG3 is a flow chart (I) of a method for switching an access mode according to an embodiment of the present disclosure. As shown in FIG3 , the steps of the method include:

Step S302, determining a first access mode adopted by an uplink passive optical fiber network PON port and/or an optical network unit ONU PON port of a main gateway, and determining a second access mode adopted by an optical network terminal OLT PON port and/or a downlink PON port of a main gateway.

It should be noted that, generally, the OLT PON port corresponds to the uplink PON port, and the downlink PON port corresponds to the ONU PON port, and the corresponding PON ports interact with each other through information and instructions such as registration information, and coordinate and switch access modes, so that the access modes adopted by the OLT PON port and the uplink PON port are unified, and the access modes adopted by the downlink PON port and the ONU PON port are unified.

Step S304: When it is determined that the first access mode and the second access mode are inconsistent, switch the first access mode to the second access mode.

Through the above steps, the embodiment of the present disclosure determines the first access mode adopted by the uplink passive optical fiber network PON port and/or the optical network unit ONU PON port of the main gateway, and determines the second access mode adopted by the optical network terminal OLT PON port and/or the downlink PON port of the main gateway; further determines whether the first access mode and the second access mode are consistent, and when it is determined that the first access mode and the second access mode are inconsistent, the first access mode is switched to the second access mode. That is, by determining whether the first access mode adopted by the uplink PON port and the second access mode adopted by the OLT PON port are consistent, if they are inconsistent, the first access mode adopted by the uplink PON port is switched to the second access mode adopted by the OLT PON port; and by determining whether the first access mode adopted by the ONU PON port and the second access mode adopted by the downlink PON port are consistent, if they are inconsistent, the first access mode adopted by the ONU PON port is switched to the second access mode adopted by the downlink PON port. The above technical solution solves the technical problem in the related art that the FTTR main gateway and the slave gateway cannot realize the switching of multiple PON modes.

In an exemplary embodiment, determining a second access mode adopted by an optical network terminal OLT PON port and/or a downstream PON port of a main gateway includes: when the upstream PON port and/or the ONU PON port receives registration information sent by the OLT PON port and/or the downstream PON port, determining the second access mode according to the registration information.

It should be noted that: OLT usually performs interactive authentication on the newly connected master gateway in the form of PLOAM or MPCP messages, and the master gateway usually also performs interactive authentication on the newly connected slave gateway (which can be equivalent to the ONU in the above embodiment) in the form of PLOAM or MPCP messages, and then the PLOAM or MPCP message can be the registration information. Due to the differences in the definition of PLOAM or MPCP messages in different PON technical standards. Therefore, the second access mode currently adopted by the OLT PON port and/or the downlink PON port can be determined based on the registration information sent by the OLT PON port and/or the downlink PON port of the master gateway to the uplink PON port and/or the ONU PON port. Among them, physical layer operations, administration and maintenance (PLOAM for short), multi-point control protocol (MPCP for short).

Exemplarily, the OLT, the uplink port, the downlink port, and the ONU all support the GPON/EPON working modes, wherein the registration information in the form of PLOAM or MPCP message corresponding to GPON is Upstream Overhead PLOAM message, and the registration information in the form of PLOAM or MPCP message corresponding to EPON is MPCP Broadcast Discovery Gate Capable&&Window=1G. Here, the registration information corresponding to GPON is simply determined as Upstream Overhead, and the registration information corresponding to EPON is determined as Discovery Gate: 1) If the second access mode adopted by the OLT is GPON, and the first access mode adopted by the uplink port of the main gateway after power-on initialization is EPON, then: the second access mode is GPON, then the registration information that the OLT PON port should send to the uplink PON port is Upstream Overhead, and then the uplink PON port can determine the OLT according to the registration information Upstream Overhead. The second access mode adopted by the PON port is GPON, and since the first access mode adopted by the upstream PON port is EPON after initialization, the first access mode does not match the second access mode, and the first access mode needs to be switched to the second access mode to re-initiate the registration process. 2) If the second access mode adopted by the downstream PON port of the main gateway after power-on is initialized to GPON, and the first access mode adopted by the ONU PON port after power-on is initialized to EPON, then: the registration information sent by the downstream port of the main gateway to the ONU PON port is Upstream Overhead, and the ONU PON port determines that the second access mode adopted by the downstream PON port of the main gateway is GPON based on the received Upstream Overhead registration information, which does not match the first access mode adopted by the ONU PON port, and then the EPON adopted by the ONU PON port can be switched to the second access mode. The corresponding GPON mode and re-initiate the registration process.

It should be noted that, in the process of interaction between the OLT and the uplink PON port of the main gateway, the mode switching operation is generally performed on the uplink PON port; and in the process of interaction between the downlink PON port and the ONU PON port, you can choose to switch the access mode adopted by the ONU PON port, or you can choose to switch the access mode adopted by the downlink PON port, that is, in the above example 2), you can also choose to switch the second access mode GPON adopted by the downlink PON port to the first access mode EPON adopted by the ONU PON port. It should also be noted that, if the optical module supports it, the uplink PON port and the downlink PON port of the main gateway can adopt different access modes without interfering with each other. It should also be noted that the above-mentioned scheme of mode switching based on registration information is generally applicable to the case where the optical module is a multi-mode optical module.

In an exemplary embodiment, before switching the first access mode to the second access mode, the method also includes: determining a first working band corresponding to the first access mode, and determining a second working band corresponding to the second access mode; when the first working band and the second working band are inconsistent, determining that the first access mode and the second access mode are inconsistent.

It should be noted that the working bands corresponding to different access modes may be different. Therefore, it is possible to determine whether the first access mode and the second access mode are the same access mode by determining whether the working bands corresponding to the first access mode and the second access mode are the same. If the first working band and the second working band are the same, the first access mode and the second access mode may be the same, but further determination is required. However, if the first working band and the second working band are different, the first access mode and the second access mode must be different, and the corresponding PON port mode switching can be performed directly.

For example, if the first access mode is GPON, the corresponding first working band is: upstream wavelength 1310nm, downstream wavelength 1490nm, and the second access mode is XEPON asymmetric, and the corresponding working band is: upstream wavelength 1270nm, downstream wavelength 1577nm. It can be determined that the first working band and the second working band are inconsistent. Therefore, the first access mode and the second access mode must be inconsistent, and a switching operation is required.

Optionally, after determining the first working band and the second working band, the following scheme is included:

1) In an exemplary embodiment, after determining the first working band corresponding to the first access mode and determining the second working band corresponding to the second access mode, the method further includes: when the first working band and the second working band are inconsistent, determining the first optical module corresponding to the first access mode and the second optical module corresponding to the second access mode; when the module types of the first optical module and the second optical module are both single-mode optical modules, sending a prompt message to the target object, wherein the prompt message is used to prompt that the module type of the first optical module or the module type of the second optical module is incorrectly selected.

When it is determined that the first working band and the second working band are inconsistent, if the optical modules corresponding to the access modes adopted by the OLT, the main gateway uplink port, the downlink port, and the ONU are all single-mode optical modules, the mode switching operation cannot be performed because the single-mode optical module only supports one access mode. You can choose to send a prompt message to the target object to prompt that the optical module type selection is wrong.

The target object is generally a staff member who can perform optical module replacement operations, or it can be a user. The prompt information can indicate which PON port optical module needs to be replaced, and provide optional replacement solutions, such as: indicating that the optical module of the upstream PON port needs to be switched, and providing the type of optical module to be switched to, or providing the access mode to be switched to by the upstream PON port, and then instructing the target object to switch the optical module type to the upstream PON port according to the optical module type, or the optical module type determined by the access mode to be switched to. Replace the optical module originally connected to the PON port.

2) In an exemplary embodiment, after determining the first working band corresponding to the first access mode and determining the second working band corresponding to the second access mode, the method further includes: in a case where the first working band and the second working band are inconsistent, determining the first optical module corresponding to the first access mode and the second optical module corresponding to the second access mode; in a case where one of the first optical module and the second optical module is a multi-mode optical module and the other optical module is a single-mode optical module, determining the third access mode adopted by the target PON port corresponding to the multi-mode optical module and determining the fourth access mode of the single-mode optical module; switching the third access mode corresponding to the target PON port to the fourth access mode.

In an exemplary embodiment, the third access mode corresponding to the target PON port is switched to the fourth access mode, including: obtaining multiple access modes allowed to be supported by the multi-mode optical module; when it is determined that the multiple access modes include the fourth access mode, switching the third access mode adopted by the target PON port to the fourth access mode.

That is, when the first working band and the second working band are inconsistent, if there is at least one multi-mode optical module in the optical modules corresponding to the first access mode and the second access mode, the third access mode currently adopted by the target PON port using the multi-mode optical module and the fourth access mode adopted by the PON port using the single-mode optical module are further determined; when the multi-mode optical module supports the fourth access mode, the third access mode currently adopted by the target PON port is switched to the fourth access mode.

Exemplarily, the condition may be set as follows: switching the access mode between the ONU PON port and the main gateway downstream PON port to unify the access modes adopted by the ONU PON port and the main gateway downstream PON port, wherein the ONU PON port adopts a single-mode optical module supporting the GPON access mode, and the downstream PON port adopts a multi-mode optical module supporting the XGPON/GPON access mode. Then: when the first access mode of the ONU PON port is GPON and the second access mode of the downstream PON port is XGPON, since the working band adopted by GPON is an upstream wavelength of 1310nm and a downstream wavelength of 1490nm, and the working band adopted by XGPON is an upstream wavelength of 1270nm and a downstream wavelength of 1577nm, the working bands of the access modes adopted by the ONU PON port and the downstream PON port are inconsistent, and thus the first access mode and the second access mode are inconsistent. At this time, it is determined whether the ONU PON port and the downstream PON port adopt a single-mode optical module and a multi-mode optical module. Then, the XGPON/GPON optical module is a multi-mode optical module, the downstream PON port is the target PON port, the XGPON adopted by the downstream PON port is determined as the third access mode, and the GPON adopted by the ONU PON port is the fourth access mode. Since the multi-mode optical module XGPON/GPON optical module adopted by the downstream PON port also supports the fourth access mode GPON, the third access mode is switched to the fourth access mode.

In an exemplary embodiment, before switching the first access mode to the second access mode, the method further includes: upon detecting that the OLT PON port and/or the downstream PON port receives a mode switching instruction, sending a target signaling to the upstream PON port and/or the ONU PON port, wherein the target signaling includes: a physical layer operation administration and maintenance PLOAM message, or an ONU management and control interface OMCI message; the target signaling carries a fifth access mode to which the OLT PON port and/or the downstream PON port is expected to switch.

Optionally, after registration and authentication, if it is determined that the first access mode and the second access mode are inconsistent, then: the mode switch can be actively initiated through a mobile phone APP, network management, NFC or web page. Optionally, the mode switch instruction can be sent to the OLT PON port and/or the downlink PON port. The mode switch instruction can be a physical layer operation management and maintenance PLOAM message, or an ONU management and control interface OMCI message, which is used to indicate that the OLT PON port and/or the downlink PON port expects the uplink The fifth access mode to which the PON port and/or the ONU PON port switches. It should be noted that: Physical Layer Operations, Administration and Maintenance (PLOAM for short); ONU Management and Control Interface (OMCI for short).

In an exemplary embodiment, after sending the target signaling to the upstream PON port and/or the ONU PON port, the method further includes: parsing the target signaling through the upstream PON port and/or the ONU PON port to obtain the fifth access mode; determining the sixth access mode currently adopted by the upstream PON port and/or the ONU PON port; when it is determined that the upstream PON port and/or the ONU PON port support the fifth access mode, switching the sixth access mode to the fifth access mode; when it is determined that the upstream PON port and/or the ONU PON port do not support the fifth access mode, sending feedback signaling to the OLT PON port and/or the downstream PON port through the upstream PON port and/or the ONU PON port, wherein the feedback signaling includes: the feedback signaling carries multiple access modes supported by the upstream PON port and/or the ONU PON port and the sixth access mode.

Optionally, when the upstream PON port and/or ONU PON port receives a mode switching instruction, it parses the mode switching instruction, and then obtains the access mode that the OLT PON port and/or downstream PON port is expected to switch to as indicated by the mode switching instruction, that is, the fifth access mode. In addition, the upstream PON port and/or ONU PON port also needs to determine the sixth access mode currently adopted by itself. Then 1) when it is determined that the optical module used by the upstream PON port and/or ONU PON port is a multi-mode optical module and also supports the fifth access mode, the sixth access mode is switched to the fifth access mode. 2) When it is detected that the optical module used by the upstream PON port and/or ONU PON port is a single-mode optical module, feedback notification signaling is sent, and the feedback notification signaling carries the sixth access mode supported by the upstream PON port and/or ONU PON port. The OLT and/or the downlink port can decide whether to switch to the fifth access mode currently adopted by itself according to the received feedback notification signaling, or inform the target object that the optical module adopted by the uplink PON port and/or the ONU PON port is a single-mode optical module. 3) When it is determined that the optical module adopted by the uplink PON port and/or the ONU PON port is a multi-mode optical module, but does not support the fifth access mode, the uplink PON port and/or the ONU PON port sends feedback signaling to the OLT PON port and/or the downlink PON port, and the feedback signaling includes all access modes (i.e., capability sets) supported by the uplink PON port and/or the ONU PON port and the sixth access mode currently adopted. Furthermore, when the OLT PON port and/or the downstream PON port receives feedback signaling, the capability set of the upstream PON port and/or the ONU PON port can be parsed from the feedback signaling, and then the seventh access mode to which the upstream PON port and/or the ONU PON port can be switched can be determined from the capability set; based on the seventh access mode, a mode switching instruction is sent to the upstream PON port and/or the ONU PON port, so that the upstream PON port and/or the ONU PON port switches the sixth access mode to the seventh access mode.

Based on the above embodiment, after registration and authentication, the process of actively switching the access mode is shown in Figures 4 and 5. The OLT and/or MFU sends a mode switching instruction to the MFU and/or SFU to instruct the MFU and/or SFU to switch the access mode, and can request the MFU and/or SFU to report its own capability set. If the MFU and/or SFU can switch the currently used access mode based on the mode switching instruction, the access mode is switched, and the access mode currently used by the MFU and/or SFU, the capability set of the MFU and/or SFU, and the access mode that the MFU and/or SFU can switch to indicated by the mode switching instruction are fed back to the OLT and/or MFU; if the optical module accessed by the MFU and/or SFU does not support the access mode to be switched to indicated by the mode switching instruction, the MFU and/or SFU sends feedback signaling to the OLT and/or MFU, and the feedback signaling includes the capability set of the MFU and/or SFU and the currently used access mode.

It should be noted that: Single Family Unit (SFU), Multi-family User Unit Multi Family Unit (MFU for short).

It should be noted that the mode switching instruction can be a physical layer operation management and maintenance PLOAM message, or an ONU management and control interface OMCI message, and the feedback signaling and feedback notification signaling can also be a physical layer operation management and maintenance PLOAM message, or an ONU management and control interface OMCI message.

In an exemplary embodiment, determining a first access mode adopted by an upstream passive optical fiber network PON port and/or an optical network unit ONU PON port of a main gateway, and determining a second access mode adopted by an optical network terminal OLT PON port and/or a downstream PON port of the main gateway, includes: determining a first optical module accessed by the upstream PON port of the main gateway and/or the ONU PON port, and determining a second optical module accessed by the OLT PON port and/or the downstream PON port, wherein the access modes supported by the first optical module include the first access mode, and the access modes supported by the second optical module include the second access mode; determining that the upstream PON port and/or the ONU PON port adopt the first access mode according to the first optical module, and determining that the OLT PON port and/or the downstream PON port adopt the second access mode according to the second optical module.

It can be understood that all access modes supported by the first optical module connected to the upstream PON port and/or the ONU PON port include the first access mode currently adopted by the upstream PON port and/or the ONU PON port, and all access modes supported by the second optical module connected to the OLT PON port and/or the downstream PON port include the second access mode currently adopted by the OLT PON port and/or the downstream PON port. Then, the first access mode and the second access mode can be determined according to the first optical module and the second optical module. Optionally, in the case where the first optical module and the second optical module are both single-mode optical modules, the current access mode can be directly determined according to the access mode supported by the single-mode optical module. Optionally, the hardware layer needs to be able to identify the access modes supported by the upstream PON port and/or the ONU PON port, and the optical modules connected to the OLT PON port and/or the downstream PON port, and notify the software layer.

Next, the access mode switching method is further described in conjunction with the following embodiments.

An optional embodiment of the present disclosure provides a method for switching the access mode of the FTTR system, which is divided into two methods, passive and active. In the passive switching method, the upper and lower PON ports of the main gateway implement PON port mode switching according to methods such as optical module bands and registration phase message content matching; in the active switching method, the PON port mode switching process is triggered by external instructions, and then the collection of upper and lower PON port capability set reporting and PON port switching according to the PON mode of the upper and lower devices are implemented through PLOAM or OMCI message interaction, so as to realize the FTTR main gateway's wide compatibility with existing PON standards and scalability for future evolution.

Specifically, in order to solve the technical problem in the related art that the FTTR master gateway and the slave gateway cannot implement the switching of multiple PON modes, the present disclosure provides the following solutions according to the embodiments, specifically including:

1. Passive switching method: During the registration and authentication phase, the passive mode switching method is used between the OLT and the uplink PON port of the main gateway, and between the downlink PON port of the main gateway and the ONU.

It should be noted that there are differences in the optical modules that match different PON access technologies. Although there are GPON/XGPON integrated optical modules at this stage, due to reasons such as manufacturing costs, 4-mode or even more-mode integrated optical modules have not yet been widely used. Therefore, in order to be compatible with existing PON technology and subsequent evolution, the hardware layer needs to be able to identify the PON modes supported by the optical modules of the upstream and downstream PON ports, and notify the software layer.

Exemplarily: 1) If the uplink PON port is connected to an XGPON single-mode optical module and the downlink PON port is connected to an XGPON/GPON combined optical module, the software layer master gateway is notified to register in XGPON mode and the slave gateway is registered in XGPON or GPON mode;

2) If the uplink PON port is connected to an XGPON/GPON multi-mode optical module and the downlink PON port is connected to an EPON optical module, The software layer master gateway is registered in XGPON or GPON mode, and the slave gateway is registered in EPON mode;

3) If the uplink PON port is connected to an EPON single-mode optical module and the downlink PON port is connected to an XGPON/GPON optical module, the software layer is notified to register the master gateway in EPON mode and the slave gateway in XGPON or GPON mode;

Optionally, due to differences in the working bands of some PON access technologies, the FTTR equipment needs to preliminarily identify the working bands of the OLT PON port, the upper and lower PON ports of the main gateway, and the ONU PON port in turn after power-on. When the OLT PON port and the upper PON port of the main gateway are both single-mode optical modules and the bands are inconsistent, the master gateway registration process is stopped and the staff is notified that the master gateway and OLT modes do not match; when the lower PON port and the ONU PON port are both single-mode optical modules and the bands are inconsistent, the slave gateway registration process is stopped and the staff is notified that the master gateway and slave gateway modes do not match; since current ONU chips generally support all modes, when the optical module only supports one mode, the number of ONU mode switching times can be significantly reduced by preliminarily identifying the working bands of the OLT PON port, the upper and lower PON ports of the main gateway, and the ONU PON port.

Furthermore, when the OLT PON port and the main gateway uplink PON port have the same band and are both multi-mode optical modules, and the downlink PON port and ONU PON have the same band and are both multi-mode optical modules (such as EPON and GPON share the Up 1310nm Down 1490nm band), in this case, whether the optical module is single-mode or multi-mode, it needs to be identified based on the registration authentication message.

Regarding identification based on registration authentication messages:

It should be noted that: OLT usually performs interactive authentication on the newly connected master gateway in the form of PLOAM or MPCP messages, and the master gateway usually also performs interactive authentication on the newly connected slave gateway in the form of PLOAM or MPCP messages. Due to the differences in the definitions of PLOAM or MPCP messages (defined as "registration information" in this disclosure) in different PON technical standards, this difference can be used to identify the current access mode. The registration information of different PON access technologies is shown in Table 2 below:

Table 2

After the preliminary identification and matching of the above optical module band information and capability set, the master gateway/slave gateway further determines whether the received registration information matches the currently initialized PON mode. If it matches, the registration process continues; if it does not match, it switches to the PON mode that matches the registration information and re-initiates the registration process.

Exemplary: Taking the switching between GPON and EPON as an example, it is assumed that the OLT, the uplink port, the downlink port, and the slave gateway all support the GPON/EPON working modes.

(1) Switching the uplink port of the main gateway

When the OLT access mode is GPON, the initialization mode of the main gateway uplink port after power-on is EPON, and the initialization mode of the slave gateway after power-on is EPON. If the initialization mode of the main gateway uplink port after power-on is EPON, and no Discovery Gate message is detected after initialization, switch the working mode of the main gateway uplink port to GPON, re-initiate the registration process, receive the Upstream Overhead message sent by the OLT, and continue the registration process.

(2) Switching the downlink port of the main gateway

When the OLT access mode is GPON, the initialization mode of the main gateway uplink port after power-on is GPON, and the initialization mode of the slave gateway after power-on is EPON, the main gateway uplink port receives the Upstream Overhead message sent by the OLT after initialization, and continues the registration process; if the initialization mode of the main gateway downlink port is GPON after power-on, and the slave gateway PON port is initialized but no Upstream Overhead message sent by the main gateway downlink port is detected, the working mode of the main gateway downlink port is switched to EPON, and the registration process is reinitiated. After initialization is completed again, the Discovery Gate message is detected and the registration process continues.

(3) Switching from Gateway

When the OLT access mode is GPON, the initialization mode of the main gateway uplink port after power-on is GPON, and the initialization mode of the slave gateway after power-on is EPON, after the main gateway uplink port is initialized, it receives the Upstream Overhead message sent by the OLT to continue the registration process; if the initialization mode of the main gateway downlink port is GPON after power-on, and the slave gateway cannot detect the Discovery Gate message sent by the main gateway after initialization, the slave gateway working mode is switched to GPON, and the registration process is re-initiated; after the initialization is completed again, the Upstream Overhead message is detected and the registration process continues.

2. Active switching method: After registration and going online, the active mode switching method between the OLT and the uplink PON port of the main gateway, the downlink PON port of the main gateway and the ONU.

In addition to the above-mentioned method of automatically negotiating the switching mode during the registration and authentication phase, you can also actively initiate mode switching through mobile phone APP, network management, NFC or Web pages after registration and going online, and send PLOAM messages to implement the master-slave gateway mode. Therefore, a series of PLOAM messages need to be designed to achieve compatibility with existing PON standards and subsequent evolution.

When mode switching is initiated externally, the OLT and the downstream PON port of the main gateway need to obtain the capability set of the upstream PON port of the main gateway and the PON port of the slave gateway. Optionally, the capability set can be obtained by sending a message (equivalent to the mode switching instruction in the above embodiment) to the upstream PON port of the main gateway and the PON port of the slave gateway.

However, it should be noted that the mode switching instruction indicates the access mode that the uplink PON port of the main gateway and the downlink PON port of the main gateway should switch to. If the uplink PON port of the main gateway and the downlink PON port of the main gateway can switch to the access mode indicated by the mode switching instruction, then there is no need to feed back their own capabilities to the OLT and the downlink PON port of the main gateway.

The message (equivalent to the mode switching instruction in the above embodiment) is defined as shown in Table 3, Table 4 and Table 5 below:

Table 3: G.984.3 Get_Set_PonMode message(Downstream)

Table 4: G.987.3 Get_Set_PonMode message(Downstream)

Table 5: G.9804.2 Get_Set_PonMode message(Downstream)

It should be noted that the above Table 3-5 shows the formats of the messages for obtaining the capability sets of the uplink PON port of the master gateway and the PON port of the slave gateway in different standards.

After receiving the above-defined message, the master gateway upstream PON port and the slave gateway PON port need to report their own capability set to the upper-level PON port. The reporting message (equivalent to the feedback signaling in the above embodiment) is defined as shown in Table 6, Table 7, and Table 8 below:

Table 6: G.984.3 Pon_Capability notify message(Upstream)

Table 7: G.987.3 Pon_Capability notify message(Upstream)

Table 8: G.9804.2 Pon_Capability notify message(Upstream)

It should be noted that the above Table 6-8 is a feedback message that the master gateway uplink PON port and the slave gateway PON port need to report their own capability set to the upper PON port after receiving the above-defined message (equivalent to the feedback message in the above embodiment). Signaling) in different standards.

Optionally, the above PLOAM message can complete the functions of reporting the PON port capability set and transmitting the PON port mode switching instruction. The above functions can also be implemented through OMCI messages. The message format is defined as shown in Table 9 below:

Table 9

The above ONU mode processing method is applicable to most of the current PON systems, including GPON, EPON, XGPON, XGSPON, XEPON asymmetric, XEPON symmetric, NGPON2 and future 50G PON and 200G PON systems.

Optionally, based on the above-mentioned contents of the optional embodiments of the present disclosure, a more specific optional embodiment is given below:

Optional embodiment 2:

FIG7 is a flow chart (III) of the access mode switching method according to an embodiment of the present disclosure, which shows the process of active mode matching between the OLT and the uplink PON port of the main gateway, the downlink PON port of the main gateway and the ONU after registration and going online, as shown in FIG7:

S701: Initiate a mode switching process on the OLT side through network management\APP\WEB\NFC and other methods;

S702: OLT sends a PLOAM or OMCI message to request the master gateway and slave gateway PON port capability set;

S703: The slave gateway and the master gateway report the capability set in turn through PLOAM or OMCI messages.

S704: OLT sends a PLOAM or OMCI message, and the master gateway and slave gateway parse the message and switch to the corresponding PON port mode;

Optionally, since in the optional embodiment of the present disclosure, both the request capability set and the mode switching instruction are sent by the OLT through a PLOAM or OMCI message, based on the above steps: the OLT can simultaneously request the capability set and the access mode switching by sending a PLOAM or OMCI message. If the master gateway and the ONU (equivalent to the slave gateway) can perform the access mode switching, it is not necessary to report the capability set, otherwise, it is necessary to report its own capability set, so that the OLT can send the PLOAM or OMCI message again based on the reported capability set, so that the master gateway and the slave gateway can parse the message and switch the corresponding PON port mode.

Based on the above embodiments, the present invention realizes the switching of FTTR uplink and downlink PON port modes through active and passive methods; improves the compatibility of FTTR system with existing PON equipment and the extensibility of future evolution standards, reduces the equipment procurement and maintenance costs of operators, and improves the resource utilization efficiency of existing communication equipment. It is suitable for home or enterprise networking applications of FTTR system, and may be combined with 100G PON or 200G PON technology in the future to provide wider bandwidth and better user experience.

In this embodiment, a switching device for access mode is also provided, which is used to implement the above embodiments and preferred implementation modes, and the descriptions that have been made will not be repeated. As used below, the term "module" can implement a combination of software and/or hardware for a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.

FIG8 is a structural block diagram of a switching device for access mode according to an embodiment of the present disclosure. As shown in FIG8 , the switching device for access mode includes:

A determination module 82 is configured to determine a first access mode adopted by an uplink passive optical fiber network PON port and/or an optical network unit ONU PON port of a main gateway, and to determine a second access mode adopted by an optical network terminal OLT PON port and/or a downlink PON port of the main gateway;

The switching module 84 is configured to switch the first access mode to the second access mode when it is determined that the first access mode and the second access mode are inconsistent.

Through the above module, after determining the first access mode adopted by the uplink passive optical fiber network PON port and/or the optical network unit ONU PON port of the main gateway, and determining the second access mode adopted by the optical network terminal OLT PON port and/or the downlink PON port of the main gateway; further determining whether the first access mode and the second access mode are consistent, and after determining the When the first access mode and the second access mode are inconsistent, the first access mode is switched to the second access mode. That is to say, by determining whether the first access mode adopted by the uplink PON port and the second access mode adopted by the OLT PON port are consistent, if they are inconsistent, the first access mode adopted by the uplink PON port is switched to the second access mode adopted by the OLT PON port; and by determining whether the first access mode adopted by the ONU PON port and the second access mode adopted by the downlink PON port are consistent, if they are inconsistent, the first access mode adopted by the ONU PON port is switched to the second access mode adopted by the downlink PON port. The above technical solution is adopted to solve the technical problem in the related technology that the FTTR master gateway and the slave gateway cannot realize the switching of multiple PON modes.

In an exemplary embodiment, the determination module 82 is further configured to determine the second access mode according to the registration information when the upstream PON port and/or the ONU PON port receives the registration information sent by the OLT PON port and/or the downstream PON port.

It should be noted that: OLT usually performs interactive authentication on the newly connected master gateway in the form of PLOAM or MPCP messages, and the master gateway usually also performs interactive authentication on the newly connected slave gateway (which can be equivalent to the ONU in the above embodiment) in the form of PLOAM or MPCP messages, and then the PLOAM or MPCP message can be the registration information. Due to the differences in the definition of PLOAM or MPCP messages in different PON technical standards. Therefore, the second access mode currently adopted by the OLT PON port and/or the downlink PON port can be determined based on the registration information sent by the OLT PON port and/or the downlink PON port of the master gateway to the uplink PON port and/or the ONU PON port. Among them, physical layer operations, administration and maintenance (PLOAM for short), multi-point control protocol (MPCP for short).

For example, the OLT, the main gateway uplink port, the downlink port, and the ONU all support the GPON/EPON working modes. The registration information in the form of PLOAM or MPCP message corresponding to GPON is Upstream Overhead PLOAM message, and the registration information in the form of PLOAM or MPCP message corresponding to EPON is MPCP Broadcast Discovery Gate Capable&&Window=1G. Here, the registration information corresponding to GPON is simply determined as Upstream Overhead, and the registration information corresponding to EPON is determined as Discovery Gate. e: 1) If the second access mode adopted by the OLT is GPON and the first access mode adopted by the main gateway upstream port after power-on initialization is EPON, then: the second access mode is GPON, and the registration information that the OLT PON port should send to the upstream PON port is Upstream Overhead, and then the upstream PON port can determine that the second access mode adopted by the OLT PON port is GPON based on the registration information Upstream Overhead. Since the first access mode adopted by the upstream PON port is EPON after initialization, the first access mode does not match the second access mode, and it is necessary to switch the first access mode to the second access mode and re-initiate the registration process. 2) If the second access mode initialized by the downstream PON port of the main gateway after power-on is GPON, and the first access mode initialized by the ONU PON port after power-on is EPON, then: the registration information sent by the downstream port of the main gateway to the ONU PON port is Upstream Overhead, and the ONU PON port determines that the second access mode adopted by the downstream PON port of the main gateway is GPON based on the received Upstream Overhead registration information, which does not match the first access mode adopted by the ONU PON port, and then the EPON adopted by the ONU PON port can be switched to the GPON mode corresponding to the second access mode, and the registration process can be re-initiated.

It should be noted that, in the process of interaction between the OLT and the uplink PON port of the main gateway, the mode switching operation is generally performed on the uplink PON port; and in the process of interaction between the downlink PON port and the ONU PON port, you can choose to switch the access mode adopted by the ONU PON port, or you can choose to switch the access mode adopted by the downlink PON port, that is, in the above example 2), you can also choose to switch the second access mode GPON adopted by the downlink PON port to the first access mode EPON adopted by the ONU PON port. It is noted that, if the optical module supports it, the uplink PON port and the downlink PON port of the main gateway can adopt different access modes without interfering with each other. It is also necessary to note that the above scheme of switching modes according to registration information is generally applicable to the case where the optical module is a multi-mode optical module.

In an exemplary embodiment, the determination module 82 is also configured to determine a first working band corresponding to the first access mode, and to determine a second working band corresponding to the second access mode; when the first working band and the second working band are inconsistent, it is determined that the first access mode and the second access mode are inconsistent.

It should be noted that the working bands corresponding to different access modes may be different. Therefore, it is possible to determine whether the first access mode and the second access mode are the same access mode by determining whether the working bands corresponding to the first access mode and the second access mode are the same. If the first working band and the second working band are the same, then the first access mode and the second access mode may be the same, but further determination is required. However, if the first working band and the second working band are different, then the first access mode and the second access mode must be different, and the corresponding PON port mode switching can be performed directly.

For example, if the first access mode is GPON, the corresponding first working band is: upstream wavelength 1310nm, downstream wavelength 1490nm, and the second access mode is XEPON asymmetric, and the corresponding working band is: upstream wavelength 1270nm, downstream wavelength 1577nm. It can be determined that the first working band and the second working band are inconsistent. Therefore, the first access mode and the second access mode must be inconsistent, and a switching operation is required.

In an exemplary embodiment, the device also includes a prompt module, which is configured to determine a first optical module corresponding to the first access mode and a second optical module corresponding to the second access mode when the first working band and the second working band are inconsistent; when the module types of the first optical module and the second optical module are both single-mode optical modules, send a prompt message to the target object, wherein the prompt message is used to prompt that the module type of the first optical module or the module type of the second optical module is incorrectly selected.

When it is determined that the first working band and the second working band are inconsistent, if the optical modules corresponding to the access modes adopted by the OLT, the main gateway uplink port, the downlink port, and the ONU are all single-mode optical modules, the mode switching operation cannot be performed because the single-mode optical module only supports one access mode. You can choose to send a prompt message to the target object to prompt that the optical module type selection is wrong.

The target object is generally a staff member who can perform optical module replacement operations, or it can be a user. The prompt information can indicate which specific PON port optical module needs to be replaced, and provide optional replacement solutions, such as: indicating that the optical module of the upstream PON port needs to be switched, and providing the type of optical module to be switched to, or providing the access mode to which the upstream PON port needs to be switched, and then instructing the target object to replace the optical module originally connected to the upstream PON port according to the optical module type, or the optical module type determined by the access mode to be switched to.

In an exemplary embodiment, the switching module 84 is also configured to determine, when the first working band and the second working band are inconsistent, a first optical module corresponding to the first access mode and a second optical module corresponding to the second access mode; when one of the first optical module and the second optical module is a multi-mode optical module and the other optical module is a single-mode optical module, determine a third access mode adopted by the target PON port corresponding to the multi-mode optical module, and determine a fourth access mode of the single-mode optical module; and switch the third access mode corresponding to the target PON port to the fourth access mode.

In an exemplary embodiment, the switching module 84 is further configured to obtain the multiple interfaces supported by the multi-mode optical module. access mode; when it is determined that the plurality of access modes include the fourth access mode, the third access mode adopted by the target PON port is switched to the fourth access mode.

That is, when the first working band and the second working band are inconsistent, if there is at least one multi-mode optical module in the optical modules corresponding to the first access mode and the second access mode, the third access mode currently adopted by the target PON port using the multi-mode optical module and the fourth access mode adopted by the PON port using the single-mode optical module are further determined; when the multi-mode optical module supports the fourth access mode, the third access mode currently adopted by the target PON port is switched to the fourth access mode.

Exemplarily, the condition may be set as follows: switching the access mode between the ONU PON port and the downstream PON port of the main gateway to unify the access modes adopted by the ONU PON port and the downstream PON port of the main gateway, wherein the ONU PON port adopts a single-mode optical module supporting the GPON access mode, and the downstream PON port adopts a multi-mode optical module supporting the XGPON/GPON access mode, then:

When the first access mode of the ONU PON port is GPON and the second access mode of the downstream PON port is XGPON, since the working bands of GPON are 1310nm for upstream wavelength and 1490nm for downstream wavelength, and 1270nm for upstream wavelength and 1577nm for downstream wavelength, the working bands of the access modes adopted by the ONU PON port and the downstream PON port are inconsistent, and thus the first access mode and the second access mode are inconsistent. At this time, it is determined whether the ONU PON port and the downstream PON port use a single-mode optical module and a multi-mode optical module. Then, the XGPON/GPON optical module is a multi-mode optical module, the downstream PON port is the target PON port, the XGPON adopted by the downstream PON port is determined as the third access mode, and the GPON adopted by the ONU PON port is the fourth access mode. Since the multi-mode optical module XGPON/GPON optical module adopted by the downstream PON port also supports the fourth access mode GPON, the third access mode is switched to the fourth access mode.

In an exemplary embodiment, the device also includes a sending module, which is configured to send target signaling to the upstream PON port and/or the ONU PON port when it is detected that the OLT PON port and/or the downstream PON port receives a mode switching instruction, wherein the target signaling includes: a physical layer operation administration and maintenance PLOAM message, or an ONU management and control interface OMCI message; the target signaling carries a fifth access mode to which the OLT PON port and/or the downstream PON port expects to switch.

Optionally, after registration and authentication, if it is determined that the first access mode and the second access mode are inconsistent, then: the mode switch can be actively initiated through a mobile phone APP, network management, NFC or web page. Optionally, the mode switching instruction can be sent to the OLT PON port and/or the downstream PON port. The mode switching instruction can be a physical layer operation, administration and maintenance PLOAM message, or an ONU management and control interface OMCI message, which is used to indicate that the OLT PON port and/or the downstream PON port expects the upstream PON port and/or the ONU PON port to switch to the fifth access mode. It should be noted that: Physical Layer Operations, Administration and Maintenance (PLOAM); ONU Management and Control Interface (OMCI).

In an exemplary embodiment, the switching module 84 is further configured to parse the target signaling through the upstream PON port and/or the ONU PON port to obtain the fifth access mode; determine the sixth access mode currently adopted by the upstream PON port and/or the ONU PON port; when it is determined that the upstream PON port and/or the ONU PON port support the fifth access mode, switch the sixth access mode to the fifth access mode; when it is determined that the upstream PON port and/or the ONU PON port do not support the fifth access mode, send feedback signaling to the OLT PON port and/or the downstream PON port through the upstream PON port and/or the ONU PON port, wherein the feedback signaling includes: the feedback signaling carries multiple access modes supported by the upstream PON port and/or the ONU PON port and the sixth access mode.

Optionally, when the upstream PON port and/or ONU PON port receives a mode switching instruction, it parses the mode switching instruction, and then obtains the access mode that the OLT PON port and/or downstream PON port is expected to switch to as indicated by the mode switching instruction, that is, the fifth access mode. In addition, the upstream PON port and/or ONU PON port also needs to determine the sixth access mode currently adopted by itself. Then 1) when it is determined that the optical module used by the upstream PON port and/or ONU PON port is a multi-mode optical module and also supports the fifth access mode, the sixth access mode is switched to the fifth access mode. 2) When it is detected that the optical module used by the upstream PON port and/or ONU PON port is a single-mode optical module, feedback notification signaling is sent, and the feedback notification signaling carries the sixth access mode supported by the upstream PON port and/or ONU PON port. The OLT and/or the downlink port can decide whether to switch to the fifth access mode currently adopted by itself according to the received feedback notification signaling, or inform the target object that the optical module adopted by the uplink PON port and/or the ONU PON port is a single-mode optical module. 3) When it is determined that the optical module adopted by the uplink PON port and/or the ONU PON port is a multi-mode optical module, but does not support the fifth access mode, the uplink PON port and/or the ONU PON port sends feedback signaling to the OLT PON port and/or the downlink PON port, and the feedback signaling includes all access modes (i.e., capability sets) supported by the uplink PON port and/or the ONU PON port and the sixth access mode currently adopted. Furthermore, when the OLT PON port and/or the downstream PON port receives feedback signaling, the capability set of the upstream PON port and/or the ONU PON port can be parsed from the feedback signaling, and then the seventh access mode to which the upstream PON port and/or the ONU PON port can be switched can be determined from the capability set; based on the seventh access mode, a mode switching instruction is sent to the upstream PON port and/or the ONU PON port, so that the upstream PON port and/or the ONU PON port switches the sixth access mode to the seventh access mode.

Based on the above embodiment, after registration and authentication, the process of actively switching the access mode is shown in Figures 4 and 5. The OLT and/or MFU sends a mode switching instruction to the MFU and/or SFU to instruct the MFU and/or SFU to switch the access mode, and can request the MFU and/or SFU to report its own capability set. If the MFU and/or SFU can switch the currently used access mode based on the mode switching instruction, the access mode is switched, and the access mode currently used by the MFU and/or SFU, the capability set of the MFU and/or SFU, and the access mode that the MFU and/or SFU can switch to indicated by the mode switching instruction are fed back to the OLT and/or MFU; if the optical module accessed by the MFU and/or SFU does not support the access mode to be switched to indicated by the mode switching instruction, the MFU and/or SFU sends feedback signaling to the OLT and/or MFU, and the feedback signaling includes the capability set of the MFU and/or SFU and the currently used access mode.

It should be noted that the mode switching instruction can be a physical layer operation management and maintenance PLOAM message, or an ONU management and control interface OMCI message, and the feedback signaling and feedback notification signaling can also be a physical layer operation management and maintenance PLOAM message, or an ONU management and control interface OMCI message.

In an exemplary embodiment, the determination module 82 is further configured to determine the first optical module to which the upstream PON port of the main gateway and/or the ONU PON port is connected, and to determine the second optical module to which the OLT PON port and/or the downstream PON port is connected, wherein the access modes supported by the first optical module include the first access mode, and the access modes supported by the second optical module include the second access mode; it is determined that the upstream PON port and/or the ONU PON port adopts the first access mode according to the first optical module, and it is determined that the OLT PON port and/or the downstream PON port adopts the second access mode according to the second optical module.

It can be understood that all access modes supported by the first optical module accessed by the uplink PON port and/or the ONU PON port include the first access mode currently adopted by the uplink PON port and/or the ONU PON port, and all access modes supported by the second optical module accessed by the OLT PON port and/or the downlink PON port include the second access mode currently adopted by the OLT PON port and/or the downlink PON port. Second access mode. The first access mode and the second access mode can then be determined based on the first optical module and the second optical module. Optionally, when the first optical module and the second optical module are both single-mode optical modules, the current access mode can be directly determined based on the access mode supported by the single-mode optical module. Optionally, the hardware layer needs to be able to identify the access modes supported by the optical modules accessed by the uplink PON port and/or the ONU PON port, and the OLT PON port and/or the downlink PON port, and notify the software layer.

Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present disclosure, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a readable storage medium (such as ROM/RAM, a disk, or an optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods of each embodiment of the present disclosure.
