Problems solved by technology

[0006] The technical problem to be solved by the present invention is: when the number of users is large, due to the user-level keep-alive detection, the internal keep-alive messages are very frequent, causing internal message congestion and increasing the load processing of the system; and the network element is abnormal When , in the process of resource release, the resource consistency between network elements cannot be guaranteed

Embodiment 1

[0058] In order to reduce the amount of internal messages, user resource keep alive based on the board level, such as figure 1 As shown, the signaling board 1 performs the keep-alive detection of the single boards for service boards 1, m. When the service boards and signaling boards are deployed in a distributed manner, the number of service boards and signaling boards is relative to the number of users. It is much less, and the resource keep-alive at the board level can greatly reduce the amount of internal messages compared to the resource keep-alive based on users and their levels in the prior art. This embodiment provides a resource keep-alive method applied to a serving gateway SGW network element. The method is based on the distributed deployment of a signaling board and a service board, such as figure 2 As shown, the method includes:

[0059] S1. The signaling board sends keep-alive detection messages to the corresponding service boards respectively;

[0060] S2. Judge whet...

Embodiment 2

[0064] Service board 1 performs single-board keep-alive detection on signaling boards 1, n. In distributed deployment, the number of service boards and signaling boards is much smaller than the number of users. Single board level Keeping the resources alive can greatly reduce the amount of internal news,

[0065] This embodiment provides another resource keep-alive method applied to a serving gateway SGW network element. The method is based on the distributed deployment of a signaling board and a service board. The method includes:

[0066] S1'. The service board sends keep-alive detection messages to the corresponding signaling boards respectively;

[0067] S2'. Determine whether the response message fed back by the signalling board is received, if so, it is determined that the signalling board is normal, and this keep-alive detection is over; otherwise, it is determined that this keep-alive detection failed, and this keepalive End of test;

[0068] S3'. Determine the failure of the...

Embodiment 3

[0075] Such as Figure 4 As shown, in the attach process, after receiving the request message from the MME, the SGW allocates local TEIDU_SGW resources, and then sends the message to the PGW network element. After receiving the successful response from the PGW network element, it obtains the PGW network element according to the PGW response message TEIDU_PGW, configure the local user plane and carry the address S_IP of the signaling board at the same time. After receiving the response from the user plane, store the user’s service board address T_IP. Normally, these user plane resources are for the signaling plane In other words, there is no need to care. For the subsequent release of resources between network elements, the TEIDU_SGW and TEIDU_PGW information of the user (PDN) need to be stored in the signaling processing node.

[0076] As described in Embodiment 1, when the service board m fails, the corresponding signaling unit can detect it. After that, the signaling board rele...

Abstract

The present invention relates to a resource keeping alive method applied to SGW network elements. The method is based on the distributed deployment of service boards and signaling boards, including: S1. The signaling boards respectively send keep alive detection messages to corresponding service boards; S2. Judging whether the response message fed back by the service board is received, if yes, then judging that the service board is normal, and this keep-alive detection ends, otherwise, judging that this keep-alive detection fails, and this keep-alive detection ends; S3. The failure of the corresponding service board is judged according to the predetermined number of keep-alive detection failures. The present invention also relates to a resource release method using the resource keep-alive method described above, the resource release method comprising: S4. when a service board fails, the service processing node corresponding to the service board fails; S5. service processing according to the fault The node searches for the user who needs to release the resource; S6. For the user who needs to release the resource, organize an error indication message according to the user TEIDU_SGW information and TEIDU_PGW information saved in the signaling node in advance, and send it to the peer network element to indicate the peer network element Release resources.

Description

Technical field [0001] The present invention relates to the technical field of wireless networks, and in particular to a resource keeping method and a resource releasing method using the resource keeping method. Background technique [0002] In the LTE (Long Term Evolution) network, for the SGW (Serving Gate Way) service gateway network element, according to the division of functional entities, it mainly includes two major functional modules: the signaling plane and the user plane, in order to satisfy load balancing and disaster tolerance For backup requirements, within the network element, both the signaling board and the service board are deployed in a distributed manner, that is, under normal circumstances, there are multiple signaling boards and service boards. In the case of a large number of users, the signaling area will be shared between On multiple signaling boards, the user plane will also be shared among multiple service boards. Logically speaking, there is a many-to-m...
