Problems solved by technology

For the PCC rules predefined in the PCEF that the PCRF does not know, the activation or deactivation is performed by the PCEF itself, and the PCRF cannot control
Thus, in figure 2 Among them, if the IP-CAN session is to be terminated in the PCEF, the activated PCEF itself pre-defined and the PCRF does not know the PCC rules, then the message in step 202 cannot carry the identification corresponding to this type of PCC rules, so in In step 203, it is impossible for PCEF to delete this type of PCC rule, so the process after step 205 cannot be executed

Embodiment 1

[0057] According to an embodiment of the present invention, a method for triggering session termination is provided, which is applied to the PCC architecture of Release 7.

[0058] Figure 4 is a flowchart of a method for triggering session termination according to an embodiment of the present invention, such as Figure 4 As shown, the method includes the following steps:

[0059] Step S402, the Policy Control and Charging Rules Function (PCRF) detects that it needs to terminate the policy control session (for example, IP-CAN session) between it and the Policy and Charging Enforcement Function (PCEF);

[0060] Step S404, the PCRF sends a request message to the PCEF, and carries the session identifier of the policy control session and the session termination indicator for indicating the termination of the policy control session in the message;

[0061] Step S406, in response to the request message, the PCEF deletes / deactivates the policy and charging control rules related to ...

Embodiment 2

[0064] According to the embodiment of the present invention, another method for triggering session termination is provided, which is applied to the PCC architecture of Release 8.

[0065] Figure 5 is a flowchart of a method for triggering session termination according to an embodiment of the present invention, such as Figure 5 As shown, the method includes the following steps:

[0066] Step S502, the Policy Control and Charging Rules Function (PCRF) detects the need to terminate the Gateway Control (Gateway Control) session between it and the Bearer Binding and Event Reporting Function (BBERF);

[0067] Step S504, PCRF sends a first request message to BBERF, and carries in the message the session identifier of the gateway control session and the session termination indicator used to indicate the termination of the gateway control session;

[0068] Step S506, in response to the request message, the BBERF deletes / deactivates the QoS rule related to the gateway control session ...

Embodiment 3

[0071] According to an embodiment of the present invention, a method for implementing session termination is provided, which is applied to the PCC architecture of Release 7. In this method, when the PCRF detects that the policy control session needs to be terminated, it sends a request message to the PCEF, which carries a session termination indication, and triggers the process of the PCEF deleting or deactivating all PCC rules related to the policy control session.

[0072] Figure 6 is a flowchart of a method for implementing session termination according to an embodiment of the present invention, such as Figure 6 As shown, the method includes the following processing:

[0073] Step S602, the Policy Control and Charging Rules Function (PCRF) detects that it needs to terminate the policy control session (for example, IP session) between it and the Policy and Charging Enforcement Function (PCEF), and sends a first request message to the PCEF , and carry the session identifi...

Abstract

The invention discloses a session termination triggering method, implementation method and system, wherein a session termination implementation method includes: PCRF detects that the policy control session between itself and PCEF needs to be terminated, sends a request message to PCEF, and sends a request message in the request message Carry the session identifier of the policy control session and the session termination indicator used to indicate the termination of the policy control session; in response to the first request message, the PCEF deletes / deactivates the policy and charging control rules related to the policy control session according to the session termination indicator , and send a first confirmation message to the PCRF; the PCEF sends a second request message to the PCRF, indicating that the policy control session is terminated; in response to the second request message, the PCRF identifies the application function session bound to the terminated policy control session, and sends a message to the PCEF Send a second confirmation message. Through the present invention, the RCRF can initiate session termination, thereby effectively terminating the session.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a 3rd Generation Partnership Project (3rdGeneration Partnership Project, 3GPP for short) packet system, in particular, to a session termination triggering method, implementation method and system in the system. Background technique [0002] In the 3rd Generation Partnership Project Phase 7 (3GPP Release7) standard system, the policy and charging functions are implemented by a policy and charging control (Policy and Charging Control, PCC for short) framework. The PCC architecture is a functional framework that can be applied to multiple access technologies, for example, it can be applied to the UMTS Terrestrial Radio Access Network (UMTS Terrestrial Radio Access Network, referred to as UMTS) of the Universal Mobile Telecommunications System (UMTS for short). UTRAN), Global system for Mobile Communication (GSM for short) / GSM Data Enhanced Evolution (EDGE) radio access network, an...
