Problems solved by technology

[0007] The policy enforcement entity establishes a connection with the PCRF of the policy connection service through the DRA management mechanism, but there is no process in the current network protocol for DRA to delete the correspondence between the pre-saved PCC policy session information and the PCRF of the policy connection service

Embodiment 2

[0086] like Figure 5 As shown, it is Embodiment 2 of the present invention, a method for session deletion initiated by PCRF in a non-roaming state, comprising the following steps:

[0087] In the 3GPP non-roaming state, the S-GW and the P-GW are connected using the GTP protocol. The exchange information on the GTP protocol includes the user ID serving the policy connection, the PDN ID, and the IP address.

[0088] Step S501, terminating the policy connection.

[0089]The S-GW and the P-GW corresponding to the policy connection in the domain complete the policy connection termination through the S5 interface.

[0090] Step S502, the policy session connection with the PCRF is terminated.

[0091] The policy control session is terminated through the S7 interface between the P-GW and the PCRF serving the policy connection in the domain.

[0092] Step S503, judging whether the policy session connection between the PCRF and the terminal is completely terminated.

[0093] The P...

Abstract

The embodiment of the invention discloses a method and a device for deleting strategy session. The method comprises the following steps: judging whether strategy session connection between strategy implementation entities is ended or not; sending a strategy session information instruction corresponding to the strategy session connection deleting to the Diameter domain routing agent DRA when the strategy session connection is ended; and receiving the response that the DRA deletes the strategy session information. By the invention, the DRA can delete the useless strategy session information and connection relation information in time so as to avoid adverse influence on normal strategy connection by useless redundant information and improve the communication service quality.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for deleting a policy session. Background technique [0002] The bearer of the next-generation communication network has already begun to switch to IP. From the perspective of the development of the communication network, it has experienced such an evolution process from the traditional circuit switching network to the IP packet switching network with separated control and bearer, and then to the all-IP multimedia network. In the process of evolving to an all-IP network, end-to-end QoS issues need to be considered in order to provide services (especially real-time services) that satisfy customers. Because the IP network can provide more types of services (such as multimedia calls, file downloads, web browsing, etc.), the network needs to be able to detect different service flows and count the flow, duration and other billing information to the billing ...
