Description

A gateway optimization method and device

technical field

The present invention relates to the technical field of wireless communication, and in particular, to a gateway optimization method and device.

Background technique

When UE (User Equipment, user equipment) accesses the network or transmits service data, it first needs to select a PGW (Packet Data Network-Gate Way, packet data network gateway)/GGSN (Gateway GPRS Support) that can connect to the access network Node, gateway GPRS support node) to establish a PDN (Public Data Network, public data network) connection, the PGW/GGSN is a core network device and is generally deployed centrally. However, with the introduction of the LTE (Long Term Evolution, Long Term Evolution) network and the rapid growth of data traffic, the PGW/GGSN may be distributed in a flatter manner.

Specifically, the current technical solution does not support dynamic optimization and adjustment of the gateway after the flat deployment of the gateway. However, in the prior art (eg, in 3GPP R10), a SIPTO (Selected IP Traffic Offload, Selected IP Traffic Offload) solution is proposed to cope with the increase in traffic. In the SIPTO technology, when an idle UE moves to a new L-PGW (local PGW)/L-GGSN (local GGSN) coverage, if a more suitable gateway is determined according to the user's location, it can be Instruct the UE to re-initiate the connection establishment request to update the gateway. However, when using this solution to update the gateway of the UE in the idle state, it is usually based on the original PDN connection of the UE or the context of the PDP (Packet Data Protocol), and it is determined that there is a more suitable When the gateway is connected, the UE is usually instructed to re-initiate the connection establishment request. Therefore, when there is always a service on the original PDN connection of the UE, the corresponding gateway cannot be updated or the ongoing service is interrupted, reducing the user's experience. experience.

In addition, the Chinese patent with the application number of 201010221138.6 and the publication number of 102316543A also discloses the following SGW (Serving Gateway, serving gateway) reselection scheme based on the SIPTO technology. In this solution, in the process of TAU (tracking area update, tracking area update) or RAU (Route Area Update, routing area update) initiated by the UE in the idle state, the old core network control device connects the data on the session of the UE Whether the flow is allowed to be notified by the SIPTO information to the new core network control device, and the new core network control device reselects the SGW for the session connection according to the notification, so as to improve the accuracy of the new core network control device to reselect the SGW for the session connection . Although this solution can improve the reselection speed of the SGW in the SIPTO scenario to improve the user's perception to a certain extent, since this solution only involves the update of the SGW, it cannot solve the most critical problem of optimizing the update of the PGW gateway.

That is to say, in the current technical solution, there is no better solution for realizing the dynamic update of the gateway after the flat deployment of the gateway. Therefore, it is urgent to provide a new gateway optimization method to solve the above problems.

Step 101: The network side device determines whether there is a local data gateway that satisfies the set condition at the location reached by the user equipment after the location movement.

Optionally, the data gateway described in this embodiment of the present invention may generally be a PGW. Of course, with the continuous development of network technologies, it may also be other corresponding data gateways, which is not limited in this embodiment of the present invention.

Further, the local data gateway that satisfies the set condition may be a local data gateway whose distance from the user equipment is not greater than a set distance threshold, or may be a local data gateway whose distance from the user equipment is not greater than a set distance threshold. On-premises data gateways with set distance thresholds and capable of offloading traffic (eg, offloading a set load). Wherein, the set distance threshold can generally be determined according to the distance between the user equipment and the original data gateway (usually a core gateway) to which the user equipment is connected, that is to say, in the embodiment of the present invention , the local data gateway that satisfies the set condition is usually a data gateway that is closer in distance than the original data gateway previously connected to the user equipment, and thus is more optimal, which is not described in detail in this embodiment of the present invention.

In addition, it should be noted that, in the embodiment of the present invention, the local data gateway that satisfies the setting conditions may be a data gateway integrated in the base station corresponding to the user equipment, or may be a data gateway set in the user equipment An independent data gateway other than the base station corresponding to the device (for example, a data gateway independently deployed in the local network), which is not limited in this embodiment of the present invention.

Further, in the embodiment of the present invention, judging whether there is a local data gateway that satisfies the setting conditions at the location reached by the user equipment after the location movement may include:

If it is determined that the user equipment is in the connected state, the user equipment can be combined with the location information of the user equipment or the information carrying the identity of the local data gateway sent by the base station corresponding to the user equipment. The information of the original data gateway that the user equipment is currently connected to is pre-stored by the network side device, and it is judged whether there is a local data gateway that satisfies the set conditions at the location reached by the user equipment after the location movement; or,

If it is determined that the user equipment is in an idle state, it can be determined whether there is a location that meets the setting at the location reached by the user equipment after performing the position movement according to the location information reported when the user equipment performs TAU or RAU Conditional on-premises data gateway.

Step 102: If it is determined that there is a local data gateway that satisfies the set condition at the position reached by the user equipment after performing the position movement, instruct the user equipment to satisfy the preset update condition based on the satisfaction of the set condition. the on-premises data gateway to perform the update of the gateway.

Optionally, if it is determined that the user equipment is a user equipment in a connected state, the user equipment is instructed to perform gateway update based on the local data gateway that satisfies the set condition when a preset update condition is met, Can include:

Send a connection update instruction to the user equipment (the connection update instruction may carry the reason for this connection update, for example, there is a local data gateway that meets the set conditions at the location that the user equipment reaches after the location movement is performed. And, this connection update instruction can also carry the identification information for uniquely identifying the local data gateway that meets the setting conditions, etc.), instructing the user equipment to directly release and correspond to the user equipment when receiving the connection update instruction The connection between the original data gateways and the connection between the local data gateways that meet the set conditions are established; Specifically, at this time, the network side device can directly issue a connection release message (such as an RRC Release message ) to issue the connection update instruction to inform the user equipment to re-establish the corresponding gateway connection; or,

Instruct the user equipment to set a time period after receiving the connection update instruction (the time period can be set according to the actual situation), or after receiving the connection update instruction and determining the connection with the corresponding original data gateway. When there is no data transmission on the connection, release the connection with the corresponding original data gateway and establish a connection with the local data gateway that satisfies the set condition; or,

Instruct the user equipment to establish a connection with the local data gateway that satisfies the set condition while maintaining the connection with the corresponding original data gateway when receiving the connection update instruction; or,

Instruct the user equipment to set the duration after receiving the connection update instruction (this duration can also be set according to the actual situation), or after receiving the connection update instruction and determining that it has new services that need to be transmitted , while maintaining the connection with the corresponding original data gateway, establish the connection with the local data gateway that satisfies the set condition.

Specifically, instructing the user equipment to establish a connection with the local data gateway that satisfies the set condition while maintaining the connection with the corresponding original data gateway may include:

Instructing the user equipment while maintaining the connection with the corresponding original data gateway, based on the same APN (Access Point Name, access point name) as the connection between the user equipment and the corresponding original data gateway or For different APNs, establish a connection with the local data gateway that satisfies the set condition.

That is to say, when it is determined that the user equipment is in the connected state and it is determined that there is a local data gateway that satisfies the set conditions at the location reached by the user equipment after moving In addition to releasing the connection with the corresponding original data gateway and establishing the connection with the local data gateway that satisfies the set condition, the user equipment can also be instructed to maintain the connection with the corresponding original data gateway At the same time, establish a connection with the local data gateway that satisfies the set conditions, so that the user equipment can simultaneously establish multiple different connections and obtain multiple different IP addresses for different gateways, and, The multiple different connections may be connections based on the same APN or connections based on different APNs, which are not limited in this embodiment of the present invention.

Further, when it is determined that the user equipment is a user equipment in a connected state, while instructing the user equipment to maintain the connection with the corresponding original data gateway, establish a connection with the local data that satisfies the set condition. After the connection between the gateways, the method may further include:

If it is determined that there is a new local data gateway that satisfies the set condition at the new location where the user equipment moves again, instructing the user equipment to update the previous local data gateway according to the new local data gateway , and keep the connection with the corresponding original data gateway unchanged, or release the connection with the corresponding original data gateway when it is determined that no data occurs in the connection with the corresponding original data gateway within the set time period .

That is to say, when the user equipment moves to a new place and there is a better local data gateway, the local data gateway connection can continue to be updated, but the original anchor point connection (that is, the connection with the corresponding original data gateway) can be maintained. connection) remains unchanged, or when it is determined that the original anchor connection has no data for a period of time, the connection is released.

In addition, it should be noted that, in order to facilitate the distinction of multiple gateway connections established by the user equipment at the same time, the network-side device may identify the multiple gateway connections established by the user equipment correspondingly, so as to distinguish whether the corresponding connection supports continuous It is a connection in which the anchor point remains unchanged, which is not described in detail in this embodiment of the present invention.

Furthermore, it should be noted that, in the embodiment of the present invention, the network-side device may also perform corresponding identification on the stored gateways currently connected to the user equipment to distinguish whether the gateways currently connected to the user equipment are The updated gateway is not described in detail in this embodiment of the present invention.

Further, when it is determined that the user equipment is in a connected state, the method may further include:

If it is determined that the user equipment does not perform a gateway update operation based on the local data gateway that satisfies the set conditions due to the time delay, the user equipment may be instructed to release the corresponding gateway when it enters the idle state from the connected state. A connection between a gateway that needs to be updated (here, the gateway can be an original data gateway that needs to be updated or a local data gateway that needs to be updated). It should be noted that, compared with the release operation involved in entering the idle state from the connected state in the prior art, the release operation here is to release the connection, not only the air interface link.

Further, after the user equipment enters the idle state, if it is determined that it needs to enter the connected state, it can be initiated by the terminal, or a corresponding connection establishment request can be initiated by the network after paging, so as to re-establish the corresponding gateway connection. This will not be repeated.

Further, in the embodiment of the present invention, if it is determined that the user equipment is in an idle state, the user equipment is instructed to, when a preset update condition is met, based on the local The data gateway, which performs the update of the gateway, can include:

Sending a connection update instruction to the user equipment, indicating that the user equipment receives the connection update instruction and determines that there is a new service that needs to be transmitted or that downlink data arrives, so that the user equipment changes from an idle state to a connected state, Release the connection with the corresponding original data gateway and establish the connection with the local data gateway that satisfies the set condition; or,

Instruct the user equipment to directly release the connection with the corresponding original data gateway and establish a connection with the local data gateway that meets the set condition when receiving the connection update instruction; or,

The user equipment is instructed to release the connection with the corresponding original data gateway and establish a connection with the local data gateway that meets the set condition after receiving the connection update instruction for a set period of time.

Further, in the embodiment of the present invention, the method may further include:

Preconfigure the continuity requirement feature of the user equipment, so that when the user equipment meets the preset update condition, according to the continuity requirement feature of the user equipment preconfigured by the network side device, based on the satisfaction Set the conditional local data gateway to perform the update of the gateway;

Wherein, the continuity requirement characteristics may include at least any number of the need to maintain continuity, the need to maintain continuity, and the preference to maintain continuity (ie, to maintain continuity as much as possible).

Specifically, the meaning of each continuity requirement can be described as follows:

1) The need to maintain continuity means that the core gateway is always used and the address of the user equipment remains unchanged;

2) No need to keep the connection means that the local data gateway can be used to allow address changes;

3) It is preferable to keep continuous (ie, keep as continuous as possible), which means that the gateway can be updated when the user experience is not seriously affected (eg, the gateway can be updated when it is determined that there is no traffic flow, etc.).

Further, the pre-configuring the continuity requirement feature of the user equipment may include:

Continuity requirement characteristics of each application (or service corresponding to each application) in the user equipment are preconfigured, and/or the continuity requirement characteristic of the APN corresponding to the user equipment is preconfigured. That is to say, the network side device may specifically configure the continuity feature of the user equipment from the perspective of application granularity or the perspective of APN granularity, which is not described in detail in this embodiment of the present invention.

Specifically, taking the configuration of the continuity demand feature of the user equipment from the perspective of APN granularity as an example, the degree of continuity demand of a certain APN can be configured in the user subscription information (such as HSS, HLR, etc.) in advance, and in the After the terminal establishes the corresponding APN connection, the continuity requirement characteristic corresponding to the APN may be stored in the network side device or in the user equipment, which is not repeated in this embodiment of the present invention.

Further optionally, as an embodiment of the present invention, by extending the configuration capability of network connection management of the network side device, such as the way of ANDSF (Access Network Discovery and Selection Function, access network discovery and selection function). Applications or APNs need to maintain continuity and which ones do not need to be pre-configured. That is, in order to distinguish the characteristics of different applications or APNs, each application or each APN in the user equipment can be configured through the network, so that a certain application or APN has the characteristics of "continuity" or "discontinuity". The example is not repeated here.

It should be noted that, while instructing the user equipment to maintain the connection with the corresponding original data gateway, while establishing the connection with the local data gateway that satisfies the set condition or after, the user equipment may Based on the above preconfigured continuity requirements characteristics, do the following:

The newly established connection is used to carry the new service and the original connection is used to carry the original ongoing service, and if it is determined that the original ongoing service is a service whose continuity requirement is less than the set threshold, the newly established connection is used to carry the service. Subsequent services, otherwise, use the original connection to carry its subsequent services; or,

The original connection is used to carry services whose continuity requirements are not less than the set threshold, and the newly established connection is used to carry services whose continuity requirements are less than the set threshold.

Further, in the embodiment of the present invention, after it is determined that there is a local data gateway that satisfies the set condition at the location reached by the user equipment after the location movement, optionally, the user equipment may also be The update attribute information of the connection between the corresponding gateways or the above-mentioned continuity requirement feature, determine whether the connection between the user equipment and the corresponding gateway can be updated, if so, perform the subsequent gateway update operation, otherwise, end this operations.

Further optionally, after determining that there is a local data gateway that satisfies the set conditions at the location reached by the user equipment after the location movement, it can also be determined according to the above-mentioned continuity requirement characteristics or other judgment conditions (such as whether cell reselection occurs or not). , or, whether the current gateway load exceeds the set load threshold, etc.), determine whether the connection between the user equipment and the corresponding gateway needs to be updated, if so, perform the subsequent gateway update operation, otherwise, end the current operation.

Whether there is a local data gateway that satisfies the set condition at the arrived location, and if so, instruct the user equipment to perform gateway update based on the local data gateway that satisfies the set condition when the preset update condition is met, so as to To solve the problem that there is no better solution that can realize the dynamic update of the gateway after the flat deployment of the gateway, and under the premise of minimizing the impact on the user's business, it can choose the most suitable for the user according to the movement of the user's location. The access gateway avoids the detour of the route to achieve the effect of optimizing the data transmission efficiency.

Embodiment 2:

Based on the same inventive concept as the technical solution described in Embodiment 1 of the present invention, Embodiment 2 of the present invention provides another gateway optimization method, as shown in FIG. 2 , which is a modification of the gateway optimization method described in Embodiment 2 of the present invention. A schematic flowchart, the gateway optimization method may include the following steps:

Step 201: The user equipment determines whether there is a local data gateway that satisfies the set condition at the position reached after the user equipment moves the position.

Specifically, similar to the relevant description in the first embodiment of the present invention, the local data gateway that satisfies the set conditions described in the second embodiment of the present invention may also generally be a distance from the user equipment not greater than the set distance A local data gateway with a threshold, or a local data gateway whose distance from the user equipment is not greater than the set distance threshold and can perform traffic offloading, which is not repeated in Embodiment 2 of the present invention.

Optionally, the user equipment determines whether there is a local data gateway that satisfies the set conditions at the position reached after the user equipment moves, which may include:

If the user equipment is in the connected state, it can be based on whether a local data gateway that meets the set conditions exists at the location that the user terminal reaches after the location movement, according to whether it receives a message from the network side device. The indication information, or, according to its own pre-stored data gateway identifier, determine whether there is a local data gateway that meets the set conditions at the location that it has moved after moving; or,

If the user equipment is in an idle state, it can be used according to whether the downlink message (such as a TAU Accept message) or broadcast message (such as a SIB message) sent by the network side device carries a message indicating the location of the user terminal. There is indication information of a local data gateway that satisfies the set condition at the position reached after the movement, and it is judged whether there is a local data gateway that meets the set condition at the position reached after the move.

Further, in the embodiment of the present invention, in addition to the downlink message or broadcast message sent by the network side device, the downlink message or broadcast message may carry a local message that satisfies the set condition at the location that the user terminal reaches after the location movement. In addition to the indication information of the data gateway, it may also carry indication information for indicating whether the local data gateway is a data gateway integrated in the corresponding base station, and/or identification information for uniquely identifying the local data gateway, For example, the IP address of the local data gateway, etc., is not limited in this embodiment of the present invention.

Step 202: If it is determined that there is a local data gateway that satisfies the set condition at the position reached after the self moves the position, then when the preset update condition is met, based on the local data gateway that satisfies the set condition, execute the gateway's local data gateway. renew.

Optionally, if the user equipment is a user equipment in a connected state, when a preset update condition is met, and based on the local data gateway that meets the set condition, performing gateway update may include:

When sensing that there is a data gateway that satisfies the set conditions at the location it reaches after moving its position, it directly releases the connection with the corresponding original data gateway and establishes a connection with the local data gateway that satisfies the set conditions. connection, that is, directly initiate the corresponding connection update process; specifically, the connection update process may include connection release, initiating a connection establishment request, and establishing a new connection, etc.; or,

After a set period of time after sensing that there is a data gateway that satisfies the set conditions at the location that you reach after you have moved yourself, or there is local data that meets the set conditions at the location you reach after sensing that you have moved When the gateway determines that there is no data transmission on the connection with the corresponding original data gateway, release the connection with the corresponding original data gateway and establish a connection with the local data gateway that satisfies the set conditions; or,

When sensing that there is a local data gateway that satisfies the set condition at the position reached after the self moves, while maintaining the connection with the corresponding original data gateway, establishes the local data gateway that satisfies the set condition. connections between gateways; or,

After a set period of time after sensing that there is a local data gateway that meets the set conditions at the location reached by the self, or after sensing that there is a local data gateway meeting the set conditions at the location reached after sensing the location When the data gateway determines that there is a new service that needs to be transmitted, the data gateway establishes a connection with the local data gateway that satisfies the set condition while maintaining the connection with the corresponding original data gateway.

Specifically, while maintaining the connection with the corresponding original data gateway, establishing the connection with the local data gateway that satisfies the set condition may include:

While maintaining the connection with the corresponding original data gateway, based on the same APN or different APN as the connection between the user equipment and the corresponding original data gateway, establish the local data that satisfies the set condition connections between gateways.

That is to say, when the user equipment is in the connected state and it is determined that there is a local data gateway that satisfies the set conditions at the location reached by the user equipment after moving In addition to updating the corresponding gateway connection through the connection between the data gateways and establishing the connection with the local data gateway that satisfies the set conditions, it is also possible to maintain the connection with the corresponding original data gateway while maintaining the connection with the corresponding original data gateway. Establishing a connection with the local data gateway that meets the set conditions to update the corresponding gateway connection, so that the user equipment can simultaneously establish multiple different connections and obtain multiple different IP addresses for different gateways , and the multiple different connections may be connections based on the same APN or connections based on different APNs, which is not limited in this embodiment of the present invention.

Further optionally, in the embodiment of the present invention, while maintaining the connection with the corresponding original data gateway, while establishing the connection with the local data gateway that satisfies the set condition, or at the same time , the method may further include:

Use the newly established connection (that is, the connection with the local data gateway that meets the set conditions) to carry the new service and use the original connection (that is, the connection with the corresponding original data gateway) to carry the original ongoing service, and if it is determined that the original ongoing service is a service whose continuity requirement is less than the set threshold, the newly established connection will be used to carry its subsequent service; otherwise, the original connection will be used to carry its subsequent service (in addition, if it is determined that a certain When there is no data transmission on the original connection, the connection can also be directly released); or,

The original connection is used to carry services whose continuity requirements are not less than the set threshold, and the newly established connection is used to carry services whose continuity requirements are less than the set threshold.

Wherein, for any service, the continuity requirement of the service may be pre-configured by the network side device or the user equipment.

That is, optionally, in the embodiment of the present invention, before step 201 or step 202, the method may further include:

Continuity requirement characteristics of the user equipment are pre-configured. Specifically, preconfiguring the continuity requirement characteristics of the user equipment may include: preconfiguring the continuity requirement characteristics of each application (or service corresponding to each application) in the user equipment, and/or, preconfiguring all Continuity requirement characteristics of the APN corresponding to the user equipment. Wherein, similar to the relevant description in Embodiment 1 of the present invention, the continuity requirement features may include at least any of the need to maintain continuity, no need to maintain continuity, and preferably to maintain continuity (ie, to maintain continuity as much as possible).

Correspondingly, when a preset update condition is met, based on the local data gateway that meets the set condition, performing the update of the gateway may include:

According to the continuity requirement characteristics of the user equipment preconfigured by the user equipment itself, or the continuity requirement characteristics of the user equipment preconfigured by the network side equipment, and based on the local data gateway that satisfies the set conditions, execute the gateway 's update.

In addition, it should be noted that, similar to the relevant description in Embodiment 1 of the present invention, which applications or APNs need to be kept continuous and which ones do not need to be kept continuous by extending the configuration capability of the user equipment side application connection management of the user equipment properties are pre-configured, which is not repeated in this embodiment of the present invention.

Further, in the embodiment of the present invention, while maintaining the connection with the corresponding original data gateway, after establishing the connection with the local data gateway that satisfies the set condition, the method also further Can include:

If it is determined that there is a new local data gateway that satisfies the set conditions at the new location where the self moves again, then according to the new local data gateway, the previous local data gateway is updated, and the corresponding original data is kept. The connection between the gateways remains unchanged, or when it is determined that no data occurs in the connection with the corresponding original data gateway for a set period of time, the connection with the corresponding original data gateway is released.

That is to say, when the user equipment moves to a new place and there is a better local data gateway, the local data gateway connection can continue to be updated, but the original anchor point connection (that is, the connection with the corresponding original data gateway) can be maintained. connection) remains unchanged, or when it is determined that the original anchor connection has no data for a period of time, the connection is released.

That is, in the embodiment of the present invention, the user equipment can be allowed to establish two or more connections with the corresponding gateway at the same time (that is, the user equipment is allowed to have two or more addresses at the same time), and one supports continuity Keeping the anchor point the same, a new gateway that can be continuously updated and optimized as the user equipment moves. That is, one address can remain unchanged to meet the needs of services that need to maintain continuity, and one address can be continuously updated to meet the needs of local grooming and nearby traffic distribution.

In addition, it should be noted that, in order to facilitate the distinction of multiple gateway connections established by the user equipment at the same time, the user equipment itself may identify the multiple gateway connections established by the user equipment to distinguish whether the corresponding connection supports continuous It is a connection in which the anchor point remains unchanged, which is not described in detail in this embodiment of the present invention.

Furthermore, it should be noted that, in the embodiment of the present invention, the user equipment may also identify correspondingly stored gateways currently connected to the user equipment to distinguish whether the gateways currently connected to the user equipment are updated or not. After the gateway, this embodiment of the present invention will not describe it in detail.

Further, if the user equipment is in a connected state, the method may further include:

If it is determined that it does not perform the gateway update operation based on the local data gateway that satisfies the set conditions due to the time delay, it releases the connection between itself and the corresponding gateway that needs to be updated when entering the idle state from the connected state. It should be noted that, compared with the release operation involved in entering the idle state from the connected state in the prior art, the release operation here is to release the connection, not only the air interface link.

Further, after the user equipment enters the idle state, if it is determined that it needs to enter the connected state, it can be initiated by the terminal, or a corresponding connection establishment request can be initiated by the network after paging, so as to re-establish the corresponding gateway connection. This will not be repeated.

Further, in the embodiment of the present invention, if the user equipment is an idle state user equipment, when a preset update condition is met, based on the local data gateway that meets the set condition, the gateway's Updates, which can include:

When it senses that there is a local data gateway that meets the set conditions at the location it reaches after moving, and it determines that there is a new service that needs to be transmitted or that downlink data arrives, so that it changes from idle state to connected state, release connect with the corresponding original data gateway and establish a connection with the local data gateway that satisfies the set conditions; or,

When sensing that there is a local data gateway that satisfies the set conditions at the location it reaches after moving its position, it directly releases the connection with the corresponding original data gateway and establishes a connection with the local data gateway that satisfies the set conditions. connection between; or,

After sensing that there is a local data gateway that meets the set conditions at the location it reaches after moving the position, release the connection with the corresponding original data gateway and establish a connection with the local data gateway that meets the set conditions.
