Embodiment 1

[0039] Embodiment 1: This embodiment shows that in the local breakout roaming scenario, both the S-GW and the P-GW are located in the visited location, and when the user attaches to the 3GPP access network, the S-GW and the P-GW obtain the information based on the information from the HSS. The IP-CAN session triggers the instruction information of the PCC function process, thereby starting the flow of the PCC function process. The processing procedure for the S-GW and P-GW proposed in this embodiment to obtain the IP-CAN session-based PCC function procedure indication information from the HSS is as follows: figure 2 shown, including the following steps:

[0040] Step 21, the UE sends an attach request to the 3GPP access network in the roaming area, and the 3GPP access network performs access authentication for the UE.

[0041] Step 22, the MME requests the S-GW and / or the P-GW to delete the relevant bearer context of the activated state of the UE;

[0042] Step 23, the MME ...

Embodiment 2

[0064] Embodiment 2: This embodiment shows that in the home routed roaming scenario, the P-GW is at the user's home location and is configured with indication information for triggering the PCC function process based on the IP-CAN session, while the S-GW is at the visiting location, When the user attaches to the 3GPP network, the S-GW obtains from the P-GW the indication information for triggering the PCC function process based on the IP-CAN session, and triggers the process of establishing a gateway control session. Embodiment 2 provides a schematic diagram of the processing flow for the S-GW to obtain from the P-GW the process indication information for triggering the PCC function based on the IP-CAN session and trigger the PCC function. image 3 As shown, it specifically includes the following steps:

[0065] In step 31, the UE sends an attach request to the 3GPP access network in the roaming area, and the 3GPP access network performs access authentication for the UE.

Embodiment 3

[0080] Embodiment 3: This embodiment shows that in a non-roaming scenario, a user accesses a non-3GPP network through a non-3GPP access gateway AGW. Charging) Obtain the indication information of triggering the PCC function process based on the IP-CAN session, transmit the indication information to the P-GW, and start the process of the PCC function process. The processing flow of the AGW provided in Embodiment 3 to obtain the IP-CAN session-based PCC function process indication information from the AAA is as follows: Figure 4 shown, including the following steps:

[0081] In step 41, an L2 layer connection is established between the UE and the non-3GPP access gateway AGW.

[0082] Step 42. The UE interacts with the AGW and AAA to perform user authentication. During the authentication process, the AAA obtains the user's access subscription data from the HSS. The subscription data includes all APN information that the UE is authorized to access and the default APN APN inform...

Abstract

The embodiment of the invention provides a method and a device for triggering a PPC (Policy Control and Charging) function, the method mainly comprises the following steps: a PCEF (Policy and Charging Enforcement Function) acquires instruction information triggering the PCC function on the basis of the IP-CAN (IP connected access network) conversation; and the PCEF triggers the PCC function according to the instruction information. By using the invention, the PCEF can judge whether to start the process of the PCC function according to the dynamically obtained instruction information triggering the process of the PCC function on the basis of the IP-CAN conversation, thereby reducing the management and the maintenance costs of an operator and helping expand the subscriber service.

Description

technical field [0001] The present invention relates to the field of network communication, in particular to a method and device for triggering a PCC (Policy Control and Charging, policy and charging control) function. Background technique [0002] The communication network has undergone an evolution from a CS (Circuit Switch, circuit switching) network to a PS (Packet Switch, packet switching) network mainly based on IP bearer. To carry out telecommunication services on an IP network, it is necessary to ensure service QoS (Quality of Service, Quality of Service), so as to meet users' requirements on communication quality. For example, when a user conducts a video call service, it is necessary to ensure clear and smooth video images during the service. When multiple types of services, such as web page browsing, file download, and video-on-demand, are simultaneously provided on the IP network, the IP network must have the ability to differentiate and charge according to diff...
