The embodiments are a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In a wireless communication system, when the air interface stability is relatively poor, the UE may not be able to respond to all PDPs or bearer setup request messages due to the inability to process multiple request messages at the same time or due to insufficient resources, thereby causing the UE to only apply to the SGSN or The MME returns a part of the PDP or bearer setup response message, and other parts of the PDP or bearer setup response message cannot be returned or returned after timeout.

Generally, when the SGSN or the MME receives a part of the PDP or the bearer setup response message, the SGSN or the MME does not return a successful response to the PGW, but waits for the UE to send other partial PDPs or bearer response messages, if the UE does not Return, then the SGSN or MME will wait for all PDPs or 承 After the timeout of the setup request message expires, the response is returned to the PGW. As a result, the normally established PDP or bearer has been waiting for other bearers that have not yet been established, and the service cannot be performed immediately, which reduces service efficiency.

In view of the above problems in the prior art, the embodiment of the present invention provides a bearer processing method, which is applied to a scenario in which a user equipment establishes multiple bearers, and can implement related services through a part of established bearers, thereby ensuring service efficiency.

The established response message assumes that the user equipment only establishes two corresponding bearers, and the user equipment sends only two bearer setup response messages to the mobility management device. Correspondingly, the mobility management device sends the response message of the two bearer setups to the gateway device according to the preset split response policy, so that the related services can be performed through the two established bearers, thereby ensuring service efficiency.

In order to solve the problem that the network device (for example, the S1 1/S4 interface) accumulates redundant retransmission messages and increases network overhead after the gateway device fails to receive the bearer setup response message, the network interface (for example, the S1 1/S4 interface) is accumulated, and the network overhead is increased. In another implementation manner, the bearer setup response message is sent to the other part of the unestablished bearer or other part that is not returned. Further, the mobility management device sends a failure response message of the other part of the bearer setup to the gateway device, so that the mobility management device sends the response message to the gateway. After the device sends the failure response message of the other part of the bearer establishment, the mobility management device and the gateway device may release the network resources occupied by the bearer setup request message, thereby reducing network overhead.

In another embodiment of the present invention, after the step 102, the mobility management device may send a request message for re-establishing other partial bearers to the gateway device, where the request message for re-establishing other partial bearers includes other information that needs to be re-established. The part carries the corresponding information. The gateway device sends a bearer setup request message to the mobility management device according to the other part that the gateway device re-establishes according to the information.

In order to solve the problem that the user equipment in the 2/3G network fails to re-establish another partial bearer request message (for example, a secondary PDP/dedicated bearer) and then resends the request message to the gateway device, resulting in an increase in network overhead, the present invention In another implementation manner, after step 102, the mobility management device may send a request message to the user equipment to re-establish another partial bearer, so that the user equipment re-establishes the other partial bearer.

It should be noted that the above mobility management device includes but is not limited to a mobility management entity. At least one of the MME or the general packet radio service technology service support node SGSN; the foregoing gateway device includes, but is not limited to, at least one of a PGW or an SGW.

Business, ensuring business efficiency;

At the same time, for other part of the unestablished bearer or other part of the bearer setup response message, the mobility management device sends a bearer setup failure response message to the gateway device, so that the mobility management device and the gateway device can release the bearer setup request message. The occupied network resources reduce network overhead.

2 is a schematic flowchart of a bearer processing method according to another embodiment of the present invention; as shown in FIG. 2, the bearer processing method in this embodiment may include:

201. The gateway device sends a bearer setup request message to the mobility management device, where the bearer setup request message includes at least two or more information corresponding to the bearer to be established.

Correspondingly, after receiving the bearer setup request message, the mobility management device sends the bearer setup request message to the user equipment;

Correspondingly, the user equipment respectively establishes a corresponding bearer according to the information corresponding to the bearer to be established included in the received bearer setup request message, and sends a bearer setup response message of the corresponding bearer to the mobile management device each time a bearer is established.

In another embodiment of the present invention, the bearer setup request message sent by the gateway device to the mobility management device may further include response policy information, where the response policy information includes separate response policy information or response waiting time or a combination of the two, etc. The mobile management device presets a separate response policy according to the response policy information, for example, sets a separate response policy according to the separate response policy information, and sets a timeout period according to the response waiting time.

Further, when the mobile management device receives the partial bearer setup response message sent by the user equipment, the mobile device sends the partial bearer setup response message to the gateway device according to the response policy before the preset timeout period; for example, assuming The bearer setup request message initiated by the gateway device by the mobile management device includes three information corresponding to the bearer to be established, and the user equipment may not be able to establish multiple bearers at the same time or may not return a bearer setup response message to the mobility management device due to insufficient resources. Assume that the user equipment only establishes two corresponding bearers, and the user equipment The mobility management device sends only two bearer setup response messages for the established bearers. Correspondingly, the mobility management device sends only two response messages of the bearer setup to the gateway device according to the preset split response policy, so that the related services can be performed through the two established bearers, thereby ensuring service efficiency.

202. The gateway device receives a response message that is sent by the mobility management device.

Further, in order to solve the problem that the network device (for example, the S1 1/S4 interface) accumulates redundant retransmission messages and increases network overhead, in order to solve the problem that the gateway device does not receive the bearer setup response message and retransmits the bearer setup request message, In another embodiment of the present invention, the mobile management device sends a bearer setup failure response message to the gateway device, so that the mobility management device and the gateway device can Translating the network resources occupied by the bearer setup request message reduces network overhead.

In another embodiment of the present invention, after the step 202, the gateway device receives the request message that is re-established by the mobile management device and re-establishes other partial bearers, where the request message for re-establishing other partial bearers includes other information that needs to be re-established. The device carries the corresponding information; the gateway device sends a bearer setup request message to the mobility management device according to the other part that needs to be re-established, and the bearer setup request message includes the need to be re-established. The other part carries the corresponding information, so that the mobility management device sends the bearer setup request message to the user equipment, so that the user equipment establishes a corresponding bearer according to the information corresponding to the other part that needs to be re-established.

It should be noted that the foregoing mobility management device includes, but is not limited to, at least one of a mobility management entity MME or a general packet radio service technology service support node SGSN; and the foregoing gateway device includes, but is not limited to, at least one of a PGW or an SGW.

When the mobile management device receives the response message of the partial bearer setup sent by the user equipment, the mobile management device sends the response message of the partial bearer setup to the gateway device before the preset timeout period according to the separate response policy, which may be implemented. Some of the established bearers carry out related services to ensure business efficiency;

At the same time, for other part of the unestablished bearer or other part of the bearer setup response message, the mobility management device sends a bearer setup failure response message to the gateway device, so that the mobility management device and the gateway device can release the bearer setup request message. Occupied network Network resources, reducing network overhead.

FIG. 3 is a signaling diagram of a bearer processing method according to another embodiment of the present invention; when the mobility management device is a mobility management entity MME, and the gateway device is a packet data network gateway (English: Packet Data Network-Gateway, abbreviated as PDN-GW) And the service gateway (English: Serving-Gateway, referred to as Serving-GW), the bearer processing method of this embodiment, as shown in FIG. 3, may include:

301. The PDN-GW sends a bearer setup request message to the Serving-GW.

For example, in the Policy Control and Charging (PCC) deployment system, the Policy and Charging Rules Function (PCRF) entity initiates an IP connection access network. : IP-Connectivity Access Network (IP-CAN for short) session modification begins. For example, the PDN-GW sends a bearer setup request message to the Serving-GW through the Create Bearer Request message, where the Create Bearer Request message carries the information corresponding to the multiple bearers to be established, and the information corresponding to the multiple bearers to be established includes, for example, the information The bearer identifier of the bearer to be established, the required parameters for the bearer to be established, the quality of service to be established (English: Quality Of Service, QOS for short) or the identifier of the bearer to be established (LBI).

In an embodiment of the present invention, the Create Bearer Request message also carries the split response policy information.

For example, you can add a cell to the Create Bearer Request message.

Response Mode, the length can be one byte. When no new cell is added or the new cell is 0, the MME is not required to respond to the response message of the bearer establishment. When the new cell is 1, the MME is instructed to respond separately. The response message that bears the establishment. The response policy information includes separate response policy information, or may also include a waiting time.

For example, the unused bit bit in the header of the Create Bearer Request carries the separate response policy information. When multiple bearers need to be created, 1 indicates that the MME separately responds to the bearer setup response message, and 0 indicates that the bearer is not separately configured. Response message; When creating a single bearer, the default setting is 0. For example, two new cell policies and a time to wait are added to the Create Bearer Request message, and each cell occupies one byte. The policy is a separate response policy information. For example, when the policy is 1, the use waits. Time, at this time carrying a Time to Wait cell, indicating the waiting time; for example, when the Policy is 2, instructing the MME to determine the waiting time according to the network status information (such as QCI or ARP), and preset the timeout according to the waiting time, or The MME configures the timeout period locally according to the network status information, where the network status information includes, for example, a service level identifier (QS Class Identification, QCI for short) or an allocation reservation priority (ARP). When the Create Bearer Request message does not carry a Policy cell or other value, the default is not to separately respond to the policy information.

302. The Serving-GW sends a bearer setup request message to the MME.

Specifically, the Serving GW sends a bearer setup request message to the MME through a Create Bearer Request message. The Create Bearer Request message carries the information corresponding to the multiple bearers to be established, and the information corresponding to the multiple bearers to be established includes, for example, the bearer identifier of the bearer to be established, the required parameters of the bearer to be established, and the quality of service to be established. English: Quality Of Service (QOS) or the identifier of the bearer to be established (English: Linked Bearer Identification, LBI for short).

303. The MME sends a bearer setup request message to the UE.

In a specific implementation, the MME may send a bearer setup request message to the base station to which the UE belongs by using the high layer signaling, and the base station to which the UE belongs sends the bearer setup request message to the UE by using the high layer signaling.

For example, the MME sends an E-RAB Setup Request message to the base station eNodeB to which the UE belongs, and requests to establish multiple bearers (for example, S1 bearers) included in the bearer setup request message, where the message carries the network access server (English: Network Access Server, referred to as NAS) message (for example, Activate Dedicated EPS Bearer Context Request message) and information of multiple bearers to be established.

The eNodeB sends an RRC CONNECTION RECONFIGURATION message to the UE, requesting to establish multiple bearers included in the bearer setup request message, and the UE responds to the RRC connection reconfiguration complete message to the eNodeB (English: RRC Connection Reconfiguration Complete), eNodeB The NAS message and the information of multiple bearers to be established are transmitted to the UE.

304. The UE sends a bearer setup response message to the MME.

In a specific implementation, after the eNodeB performs radio resource and S1 resource allocation, the eNodeB sends the packet to the MME. E-RAB Setup Response message;

Suppose the UE sends a Direct Transfer message to the eNodeB after establishing a bearer. Direct

The Transfer message carries the response message of the bearer establishment (for example, Activate Dedicated EPS

The bearer Context Accept message indicates that the dedicated bearer is successfully established, and the eNodeB can send the response message generated by the eNodeB to the MME message by using the Uplink NAS Transport message.

305. The MME sends a success response message of the bearer setup to the Serving-GW.

Specifically, it is assumed that the MME receives the response message sent by the UE through the eNodeB before the preset timeout period, and the MME sends the Serving message through the Create Bearer Response message.

The GW sends a success response message of the bearer establishment, where the Create Bearer Response message carries the IP address of the eNodeB, the tunnel endpoint identifier (English: Tunnel Endpoint Identification, TEID for short), and the bearer identifier assigned by the MME (English: Bearer Identification, BI for short) ) Wait.

If the MME receives or does not receive the response message of the bearer setup sent by the UE after the preset timeout period, step 307 is performed.

306. The Serving GW sends a success response message of the bearer establishment to the PDN-GW.

Specifically, the Serving GW sends a successfully generated response message to the PDN-GW through the Create Bearer Response message.

Repeat steps 304-306 until all bearers are successfully established.

307. The MME sends a failure response message of the bearer establishment to the Serving-GW.

Assuming that the MME receives or does not receive the response message of the bearer setup sent by the UE after the preset timeout period, the MME sends a failure response message to the Serving-GW through the Create Bearer Response message.

308. The Serving-GW sends a failure response message of the bearer establishment to the PDN-GW.

Optionally, the MME and the Serving-GW and the PDN-GW release the network resources occupied by the Create Bearer Request message.

309. The MME sends a re-established request message to the UE for the bearer that fails to be established. Specifically, in order to re-establish a failed bearer as soon as possible, the MME may send a re-established request message by using a Deactivate Dedicated Bearer Request message, where the Deactivate Dedicated Bearer Request message may carry a re-establishment reason (eg, Reactivation Request), indicating that the UE is directed to Establish a failed flow Cheng.

After receiving the eactivate Dedicated Bearer Request message, the UE may use the existing process to initiate a resource allocation request to the eNodeB and re-establish the bearer. The present invention does not limit this. Or

310. The MME sends a re-established request message to the Serving-GW for the bearer that failed to be established.

Specifically, in order to re-establish the failed bearer as soon as possible, the MME sends a re-established request message to the Serving-GW through a Bearer Resource Command message, where the Bearer Resource Command message carries the bearer information that fails to be established, and the bearer Resource Command message is also carried. There is a process transaction identifier (English: Procedure Transaction Identification, referred to as PTI).

The Serving-GW re-initiates the bearer setup request for the bearer that fails to be established according to the Bearer Resource Command message. The specific procedure is the same as that of 301 and 306, and will not be described again.

In the embodiment of the present invention, the MME receives the response message of the partial bearer setup sent by the user equipment according to the split response policy, and sends the partial response bearer success response message to the Serving-GW and the PDN-GW. The other part carries the failure response message that is established, and the related services can be implemented through the part of the established bearer to ensure the service efficiency;

At the same time, the MME sends a bearer setup failure response message to the Serving-GW and the PDN-GW for other bearer-initiated or non-returned bearer setup response messages, so that the MME and the Serving-GW and the PDN-GW can be released. The network resource occupied by the bearer setup request message reduces network overhead.

401. The PDN-GW sends a bearer setup request message to the Serving-GW.

For example, in the policy control and charging (English: Policy Control and Charging, PCC for short) deployment system, the policy and charging rules function (English: Policy and Charging The Rules Function (referred to as PCRF) entity initiates an IP connection access network (English: IP-Connectivity Access Network, IP-CAN for short). For example, the PDN-GW sends a bearer setup request message to the Serving-GW through the Create Bearer Request message, where the Create Bearer Request message carries the information corresponding to the multiple bearers to be established, and the information corresponding to the multiple bearers to be established includes, for example, the information The bearer ID of the bearer to be established, the required parameters for the bearer to be established, the quality of service to be established (English: Quality Of Service, QOS for short) or the LBI to be established.

In an implementation manner of the present invention, the Create Bearer Request message also carries the split response policy information. For specific implementation, for example, the cell may be added in the Create Bearer Request message or the unused bit bit in the message header may be utilized. Carry separate response policy information.
