Description

 System, device and method for supporting fixed and mobile convergence

 The present invention relates to the field of communications, and in particular, to a system, apparatus, and method for supporting fixed and mobile convergence. Background of the invention

 At present, how to integrate fixed network and mobile network resources to achieve fixed mobile convergence (FMC, Fixed Mobile Convergence) has become a hot topic.

 For FMC, considering the difficulty of access network convergence, the existing research results are basically concentrated on the three aspects of network level convergence, service level integration and terminal level integration. The main focuses are:

 Network-level convergence: Due to the evolution of the Internet Protocol (IP) network to bearer and control separation and the rise of IP Multimedia Subsystem (IMS), it is possible to unify the core network of mobile services and fixed services; Simply build a core network and set up related processors and systems to use both fixed and mobile access.

 Convergence at the service level: Supports the convergence of multiple services under the premise of unified service standards. Users can freely choose bundles of multiple services according to their needs, and support the services through unified bills. Users do not care about the services they use. Is provided through a fixed network or a mobile network.

 Convergence at the terminal level: A user terminal that can be used on both mobile and fixed networks.

Currently, the focus of solutions related to fixed and mobile convergence is focused on the core network layer. Convergence between the face and the business level, there are few considerations about the integration of the access level.

 Referring to Figure 1, Figure 1 shows a prior art system for implementing FMC. The basic idea of the system shown in Figure 1 is: Use wireless devices to solve the problem of fixed access data transmission. It can be seen that the system in Figure 1 uses a wireless Backhaul solution to replace the fixed network transmission network to meet the scenario where the fixed transmission network is difficult to lay; however, the system in Figure 1 only uses the fixed wireless access device as the transmission network. A sub-node, in fact, can not achieve the integration of the business level and the terminal level, so it is not a true FMC.

 Referring to Figure 2, Figure 2 is another prior art system for implementing FMC. In FIG. 2, the wireless base station and the fixed access device are two independent systems, wherein the external transmission unit of the wireless base station and the corresponding user board (the interface type are the same) in the fixed access device are connected, and then through the fixed access device. The upstream board is connected to the public transmission network. In practical application, the implementation of the system shown in Figure 2 is actually to put the mobile communication device into the fixed access device, and directly use the accessed network resources to transmit the wireless user data together with the fixed access data. And at the end of the public transmission network close to the base station controller, the wireless transmission data stream is separated by the transmission device to interface with the base station controller.

 It can be seen that the system shown in Figure 2 only places the fixed access device and the wireless access device in a single machine rejection, so two separate master, clock, transmission and operation and maintenance systems are required. Moreover, as the wireless base station supports the gradual increase of traffic and the coverage distance of the base station, the radius served by the fixed access device is usually much larger than that of the wireless base station supporting the high-speed service, resulting in a large number of wireless base stations requiring additional Site address.

 In addition, since the fixed access network and the conventional wireless base station have different requirements on the site (for example, the wireless base station generally needs to be as close as possible to the sky surface, the installation of the antenna needs to be considered), so the wireless base station is placed in a fixed access. The device rejection of the device is only applicable to the networking mode in which the wireless baseband part is placed on the fixed access device and the RRU is extended. The application scenario is greatly limited.

As can be seen from the above, neither the systems in Figures 1 and 2 can achieve true FMC. Summary of the invention

 In view of this, the main object of embodiments of the present invention is to provide a system and method for supporting fixed and mobile convergence to implement FMC.

 Another object of embodiments of the present invention is to provide an apparatus that supports fixed and mobile convergence to implement FMC.

 To achieve the above objective, the technical solution of the embodiment of the present invention is implemented as follows: The embodiment of the present invention discloses a system for supporting fixed and mobile convergence, and the system includes a universal base station controller GBSC and a universal access network device GANE;

 The GANE is configured to process, by using a wireless transmission protocol, a fixed user data stream as mobile user data, and send the processed data to the GBSC; and is further configured to distinguish fixed user data from data from the GBSC. Streaming and moving user data;

 The GBSC is configured to interact with the GANE using a wireless transmission protocol.

 The embodiment of the invention further discloses a user terminal supporting fixed and mobile convergence, the user terminal comprising a wireless user data processing part, a fixed user data processing part and a common part;

 The wireless user data processing portion for receiving and processing wireless user data; the fixed user data processing portion for receiving and processing fixed user data; the public portion for processing a wireless user data portion and / or the data sent by the fixed user data processing section is processed and output, and the data is transmitted to the wireless user data processing section and/or the fixed user data processing section.

 The embodiment of the invention also discloses a method for supporting fixed and mobile fusion, the method comprising:

In GANE, mobile user data and fixed user data are distinguished when processing downlink data from GBSC; when processing uplink data, respectively processed mobile user data and fixed user data are output to GBSC in a data transmission format required by a wireless transmission protocol. . Compared with the prior art, the system, the device and the data transmission method provided by the embodiments of the present invention can implement the FMC. For GANE, you only need to insert some boards that involve fixed access into the traditional base station and upgrade the control and maintenance software to increase the support for fixed access. This eliminates the need for a mobile operator to provide a network for supporting fixed access. It also enables fixed operators to obtain the benefits of FMC services brought about by the introduction of mobile access, and further meets the requirements for capacity expansion and evolution of fixed access. .

 The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

The system for supporting fixed and mobile convergence provided by the embodiments of the present invention includes a core network, a universal base station controller, and a universal access network device connected in sequence; wherein, the core network, the universal base station controller, and the universal access network device Fixed user data with wireless transmission protocol The stream is processed as mobile user data.

 The user terminal supporting the fixed and mobile convergence provided by the embodiment of the present invention includes a wireless user data processing part, a fixed user data processing part, and a main control and operation and maintenance unit; wherein the wireless user data processing part is used for wireless data Processing, and performing data interaction with the fixed user data processing portion; the fixed user data processing portion is configured to perform data interaction and data processing with the wireless user data processing portion and other fixed user terminals; the master control and operation The maintenance unit is configured to perform unified control, operation and maintenance on the wireless user data processing part and the fixed user data processing part.

 The method for supporting fixed and mobile convergence provided by the embodiment of the present invention is applied to a network including a core network, a universal base station controller, and a universal access network device, and the method includes: distinguishing mobile user data and fixed user data when processing data And processing the fixed user data in the data transmission format required by the wireless transmission protocol.

 Referring to FIG. 3, FIG. 3 is a system for implementing an FMC according to an embodiment of the present invention. In FIG. 3, the data stream related to the fixed access may be transparently transmitted as data of the mobile user in the traditional mobile communication network, and the data of the fixed access and the wireless access may be separated in the access device, and The separated fixed access data and the wireless access data are separately processed, and the fixed access data and the wireless access data that are processed are respectively sent to the fixed user and the mobile user through different physical interfaces.

 The system shown in Figure 3 consists of a core network (CN, Core Network), a general base station controller (GBSC), a general access network equipment (GANE), and a user terminal.

The user terminal can be divided into a mobile user terminal (MT, Mobile Terminal), a general user terminal (GT, General Terminal), and a fixed user terminal (FT, Fixed Terminal). Among them, the relatively traditional MT only supports wireless access; the GT can directly receive wireless signals through the antenna, or directly access the fixed access network through the cable; The FT only supports cable access. The CN is divided into a Circuit Domain Core Network (CS-CN) that interfaces with the Public Switched Telephone Network (PSTN) and a Packet Domain Core Network (PS-CN) that interfaces with the Packet Data Serving Node (PDSN). GBSC can implement resource management and link control for fixed users and mobile users, establishment of transmission links, framing and distribution of data streams. GANE is used to provide the antenna interface and radio remote unit (RRU) interface required for wireless access, and also provides a cable interface that supports fixed access.

 In the system shown in FIG. 3, due to the introduction of fixed access, the transmission traffic between the various devices is greatly increased; in addition, the protocol for data transmission for wireless access and fixed access is completely based on the standard transmission protocol. . It should be noted that: Due to the huge difference in traffic requirements between wireless access and fixed access, and the complexity of wireless link establishment and radio resource management is much greater than fixed access, CS-CN, PS-CN, GBSC and GANE The fixed access user and the wireless access user are separately managed and controlled, and a total management control center is required at each node to coordinate the resource allocation of the wireless access and the fixed access user.

 For example: Set resource management modules and resource management centers for mobile access and fixed access in CN, GBSC, and GANE, respectively. The resource management module for mobile access is used for resource management of mobile user data; the resource management module for fixed access is used for resource management of fixed user data; and is set to CN, GBSC. The resource management center in the GANE is configured to perform traffic scheduling and resource allocation on the resource management modules set in the CN, GBSC, and GANE, respectively.

 The internal structure of GANE can be various, as shown in Figures 4 and 7. The following is an example of each figure.

Referring to FIG. 4, FIG. 4 is a schematic diagram of a logical structure of a GANE according to a first embodiment of the present invention. The device consists of three parts: a public part subsystem, a fixed access processing subsystem, and a wireless access processing subsystem. The public part subsystem is provided with a common device to which the fixed access processing subsystem and the wireless access processing subsystem need to be applied: a wireless transmission protocol processing unit and a master control, a clock, and an operation and maintenance unit. Specifically, the wireless transmission protocol processing unit implements the termination of the wireless transmission protocol and converts it into an internal communication protocol of the wireless access processing subsystem, and determines according to the attributes of the user data (indicating mobile user data or fixed user data) Whether the data is distributed to the network side baseband processing unit or the fixed access uplink processing unit.

 The main control, clock, and operation and maintenance unit provide the reference signal of the entire GANE, and implement functions such as signaling processing, service control, user management, device management, operation and maintenance, and logging.

 The fixed access processing subsystem is configured to implement uplink and downlink data processing for fixed user access, and is composed of a fixed access uplink processing unit and a user interface processing unit. The fixed access uplink processing unit is configured to adapt the fixed user data to the data transmission format required by the wireless transmission protocol, realize transmission and aggregation of multi-user, multi-board/module user data, and complete required service quality ( QoS) control processing. The user interface processing unit is configured to complete the processing of the same type of transmission port and the bearer protocol, and implement transmission and aggregation of user data and QoS control processing as needed.

The radio access processing subsystem is composed of at least a network side baseband processing unit, a baseband radio frequency interface unit, and a network side radio frequency processing unit. The network side baseband processing unit is configured to implement baseband processing functions such as wireless data frame protocol processing, encoding and decoding, modulation and demodulation, spread spectrum, and digital splitting. The baseband radio frequency interface unit is configured to implement data aggregation and distribution between the network side baseband processing unit and the radio frequency processing unit in the network side, and reserve an interface for supporting the RRU. The RF processing unit in the network side implements the shaping, filtering, baseband pre-distortion, digital-to-analog/analog conversion, frequency conversion, small-signal amplification, filtering, power amplification, low-noise amplification, duplex filtering, etc. The output signal interacts with the mobile user terminal through the air interface through the antenna. Referring to FIG. 5, FIG. 5 is a physical architecture diagram of the GANE in FIG. Corresponding to FIG. 4, the physical implementation of GANE in FIG. 5 is also composed of a public part, a fixed access part, and a wireless access part.

 The public part is composed of a wireless transmission protocol processing board, a main control clock switch board, and a public board (such as a power board). In particular, the wireless transmission protocol processing board is a physical implementation carrier of the wireless transmission protocol processing unit. The master clock switch board is used to implement the functions of the master, clock, and operation and maintenance unit. In addition, in order to facilitate the data communication between the service boards, the function of the data exchange center is introduced on the main control clock exchange board from the perspective of physical implementation. The data exchange center is configured to implement data exchange between a wireless access user board such as a baseband processing board, a fixed access user board, a wireless transmission protocol processing board, and a main control clock exchange board.

 Generally, the data exchange center and the main control, the clock, and the operation and maintenance unit are set together on the same board. However, when the number of boards to be served is large and the processing capability is high, the data exchange center can be separately set to the single. On the board. In addition, the function of the wireless transmission protocol processing board can be implemented in the main control clock switching board, which reduces the cost by reducing the number of boards.

 The mobile access portion is composed of a connected baseband processing board, a baseband radio frequency interface board, and a medium RF processing board. The baseband processing board is a physical implementation carrier of the network side baseband processing unit; the baseband radio frequency interface board is a physical implementation carrier with a radio frequency interface unit; and the central radio frequency processing board is a physical implementation carrier of the radio frequency processing unit in the network side.

The fixed access part is composed of an uplink board and a plurality of user boards. The uplink board is a physical implementation carrier that is fixedly connected to the uplink processing unit, and the user board is usually a physical implementation carrier of the user interface processing unit. Different user boards (such as ADSL2 user board, POTS user board, VDSL2 user board, etc.) can support different interface types or handle different protocols, and can output multiple cable interfaces and support QoS processing of the single ticket. The fixed access upstream data flow direction is: fixed access user→user board→data exchange center→uplink board→data exchange center→wireless transmission The transmission protocol processing board; the downstream data flow direction is opposite to the upstream data flow.

 In an actual application, when a subscriber board can meet the requirements of a fixed access user, the uplink board does not need to be configured; the fixed access upstream data flow direction is: fixed access user→user board→data exchange center→wireless transmission The protocol processing board, the downstream data flow direction is opposite to the upstream data flow. The function of the uplink board can be implemented in the wireless transmission protocol processing board. At this time, the transmission and aggregation operation of the fixed transmission data of the wireless transmission protocol board changes: by sending a packet to the uplink board and directly changing to the user. The number of boards is used for data distribution and aggregation. In this case, the fixed access upstream data flow direction is: fixed access user → user board → data switching center → wireless transmission protocol processing board integrated with the uplink function; the downstream data flow is opposite to the upstream data flow.

 The radio access function entity in FIG. 5 is used to implement all functions of wireless data framing to the antenna, and the physical structure is the same as that of the conventional base station, generally consisting of a baseband processing board, a baseband radio frequency interface board, and a wireless transceiver (including The amplifier is constructed with a duplexer and also supports RRU access.

 The physical implementation involved in FIG. 5 can be placed in the same chassis in the backplane design, structural design, single board and module configuration, and the baseband boards of the common part, the fixed access part and the wireless access part are all placed in the same chassis; In order to fully utilize the slot resources and increase the flexibility of the configuration, the structure size of the service board slot and the backplane connector definition of the fixed access and mobile access are as compatible as possible to support the intermixing of various service boards. . In addition, when the fixed access board and the wireless access board occupy different chassis (including the same rejection or different rejection scenarios), the wiring will be from the frame (referring to the chassis without the public board). The data, control, clock, and operation and maintenance signals are connected to the main frame (the chassis with the common board) for unified control and operation and maintenance.

As can be seen from FIG. 4 and FIG. 5, in the communication network supporting FMC, when the user data stream is transmitted through the mobile communication network, the user data stream is terminated by the wireless transmission protocol processing unit, and is distinguished by the fixed User data flow and wireless user data The fixed user data stream and the wireless user data stream are respectively sent to the fixed access processing subsystem and the wireless access processing subsystem for processing, and the fixed user data and the mobile user data that are processed are respectively passed through the air interface and the user. The cable is sent to the user terminal.

 Referring to FIG. 6, FIG. 6 is a logic architecture diagram of a GANE supporting FMC and its supporting terminal business plane according to an embodiment of the present invention, and only the device concerned for the description of FIG. 6 is shown in the structure diagram. In Figure 6, in the downstream direction, the GANE first receives the information flow of the base station controller, and the information flows through the wireless transmission protocol processing unit to terminate the wireless transmission protocol, and distinguishes the fixed user data stream from the wireless user data stream.

 The wireless user data stream is processed by the base station wireless channel and transmitted through the antenna, and is received by the processing unit. After that, the terminal wireless channel performs wireless channel processing on the received signal to generate a baseband data signal, and then processes the source data. The unit processes to generate a voice or data stream. The fixed user data stream is then sent directly to the source data processing unit of the user terminal via the user logical connection and processed by the source data processing unit to generate a voice or data stream. The upstream data flow direction is opposite to the downstream data flow direction, and will not be described here.

 It can be seen from Fig. 6 that in the GANE, for the downlink direction, the wireless user data can be processed by the traditional wireless channel and sent to the user terminal via the air interface; or can be sent to the user terminal through the user logical connection by means of a wired connection. The upstream data flow is opposite to the downstream data flow.

 It should be noted that the data streams of the locations of A, B, and C, and D in Figure 6 are identical. If the data stream format of the location is different (for uplink and downlink respectively), it needs to be in B and The corresponding data format adaptation is performed on the link corresponding to D (can be implemented on the base station side or on the terminal side).

Referring to FIG. 7, FIG. 7 is a schematic diagram of a logical structure of a GANE according to a second embodiment of the present invention. As in Figure 4, the GANE shown in Figure 7 is also composed of the public part subsystem, the fixed access processing subsystem, and none. The line access processing subsystem consists of three parts. Also, GANE can communicate with MT, GT, and FT.

 Specifically, the common part subsystem and the radio access processing subsystem in FIG. 7 are the same as the common part subsystem and the radio access processing subsystem in FIG. 4, and details are not described herein again.

 The fixed access processing subsystem consists of a fixed user data distribution and aggregation unit. The fixed user data distribution and aggregation unit plays different roles in the uplink and downlink directions: in the downlink direction, it is responsible for distributing the received fixed access data stream at the user granularity, and each user corresponds to an external physical port; In the uplink direction, it is responsible for aggregating the uplink data of each fixed user and sending it to the wireless transmission protocol processing board for processing. In addition, the interface data format conversion function may also need to be implemented in the fixed access processing subsystem.

 See Figure 8 and Figure 8 for the physical architecture of GANE in Figure 7. Corresponding to Figure 7, the physical implementation of GANE in Figure 8 is also composed of a common part, a fixed access part, and a wireless access part.

 The public part is composed of a wireless transmission protocol processing board, a main control clock switching board, and a public board. Specifically, the transport protocol processing board is a physical implementation carrier of the wireless transmission protocol processing unit. The main control clock switch board is used to implement the functions of the main control, the clock, and the operation and maintenance module. In addition, in order to facilitate the data communication between the service boards, the data exchange is introduced on the main control clock switch board from the perspective of physical implementation. The function of the center.

 Generally, the data exchange center and the main control, the clock, and the operation and maintenance unit are set together on the same board. However, when the number of boards to be served is large and the processing capability is high, the data exchange center can be separately set to the single. On the board. In addition, the function of the wireless transmission protocol processing board can be implemented in the main control clock switching board to reduce the cost by reducing the number of boards.

The fixed access part is composed of a plurality of split circuit boards, and the split circuit board is used to implement functions such as uplink combining, downlink splitting, and external transmission interface driving of multiple users; when the data formats of the base station and the terminal side are different , also to complete the data format conversion processing function, its main purpose is to use The user transparently transmits the data to the target user terminal. It should be noted that the transmission interface between the split circuit board and the user terminal is recommended to use the physical bus interface between the terminal wireless channel and the source data processing unit as shown in FIG. 6; of course, in practical applications, it can also be applied. Other standard physical interfaces (such as: Serdes, xDSL, POTS, VDSL, FE/GE, RS485, etc.), can also be superimposed with other special transport protocols (such as: HDLC, IP, ATM and other standard protocols or custom transport protocols) .

 The radio access function entity in FIG. 8 is used to implement all functions of framing wireless data to the antenna, and the physical structure is the same as that of the conventional base station, generally consisting of a baseband processing board, a baseband radio frequency interface board, and a wireless transceiver (including The amplifier is constructed with a duplexer and also supports RRU access.

 In addition, the wireless processing boards such as the split circuit board and the baseband processing board have the same interface requirements as the backplane, and it is easy to implement the slot compatible design, so the split circuit board and the wireless processing board can be easily put together in one chassis. In the middle, the slot space is maximized by supporting the hybrid insertion. When you need more baseband processing boards and split-boards on your configuration, you can configure multiple business boxes.

 It should be noted that: When the number of fixed access users that need to be accessed is small, you can remove the dedicated switchboard and directly pass the panel of the baseband frame that is attached to the data exchange center (such as the wireless transmission protocol processing board). , main control clock switch board, baseband processing board, etc.) interface input and output data.

 Referring to FIG. 9, FIG. 9 is a structural diagram of a user terminal according to an embodiment of the present invention; the user terminal is implemented by introducing a fixed access subscriber line on a conventional mobile terminal, and the fixed access subscriber line is used for directly transmitting wireless Baseband data.

Specifically, the user terminal shown in FIG. 9 includes a radio frequency processing unit, a terminal side baseband processing unit, a source data processing unit, a main control and an operation and maintenance unit, and other peripherals (such as a display screen, a keyboard, and a speaker) in the terminal side. , pickups, etc.). The source data processing unit is sequentially connected to the terminal side baseband processing unit and the terminal side radio frequency processing unit; The operation and maintenance unit is respectively connected to a peripheral device such as a source data processing unit, a terminal side baseband processing unit, a display screen, a keyboard, etc.; the source data processing unit is also connected to a peripheral such as a fixed access user, a speaker, a pickup, and the like.

 Specifically, the main control and operation and maintenance unit is used to implement control and management of all functional modules and resources in the user terminal. It should be noted that the physical port and format of the fixed access subscriber line need to be used with the corresponding GANE.

 In the downlink direction, the source data processing unit can receive both the antenna and the terminal side radio frequency processing unit (implementing filtering, low noise amplification, down conversion, analog to digital conversion, and digital intermediate frequency processing), and the terminal side baseband processing unit (implementing The user plane baseband data sent by the demodulation and decoding functions can also directly receive the user plane baseband data that has not been processed by the wireless channel through the user cable. If the data format received by the above two methods is different, the source data processing unit needs to perform format conversion on the fixed access user data, and then determine one of the input as the data source for subsequent processing. For the voice data, after the voice data processing unit realizes the voice signal processing, it is output through the speaker; for the data service, the data processed by the source data processing unit is directly sent to the display after being managed and controlled by the main control and operation and maintenance unit. The screen is displayed or sent to other peripherals. The upstream data flow is opposite to the process of downstream data flow.

 It can be seen that the user terminal shown in FIG. 9 can directly receive the wireless signal through the antenna, and can directly receive the user data stream sent by the base station without the wireless channel transmission through the user cable. In a specific application, for a mobile scenario, the user terminal can access by wireless; in a fixed scenario, the user terminal can switch to the user cable access mode, and can further turn off the power of the wireless processing part circuit.

Referring to FIG. 10, FIG. 10 is a structural diagram of a user terminal according to another embodiment of the present invention. Compared with FIG. 9, the user terminal shown in FIG. 10 simply removes the functions related to the wireless processing section (including the radio frequency processing unit and the terminal side baseband processing unit in the terminal side). From Fig. 9, fixed access can be supported by simply introducing a fixed access subscriber line on the cornerstone of the conventional mobile user terminal. In fact, the fixed access subscriber line is typically the subscriber cable.

 As can be seen from the above, for GANE, it is only necessary to insert a board that involves fixed access into a traditional base station and upgrade the control and maintenance software to increase support for fixed access. This eliminates the need for a mobile operator to provide a network for supporting fixed access. It also enables fixed operators to obtain the benefits of FMC services brought about by the introduction of mobile access, and further meets the requirements for capacity expansion and evolution of fixed access. .

 It can be seen from the above that the system, the device and the data transmission method provided by the embodiments of the present invention can implement the FMC.

 The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modifications, equivalents, improvements, etc., which are made within the spirit and principles of the present invention, should be included. It is within the scope of the invention.
