Problems solved by technology

[0009] However, since the reporting mechanism of PCRF to SPR is based on the user level, when an IP-CAN session ends, if the UE still has other IP-CAN sessions and during the IP-CAN session, the UE initiates a new IP-CAN session. CAN session, at this time, the duration of UE subscription and / or the remaining amount of traffic obtained from SPR does not match the actual remaining amount, which affects the threshold accuracy of new IP-CAN session usage monitoring
For example, when a newly initiated IP-CAN session selects a PCRF, the same PCRF as the existing IP-CAN session is not selected (for example, in the case of multiple PCRF load sharing), which will cause the selected PCRF to obtain the user's business from the SPR The information is not precise enough to affect the PCC strategy formulated by the PCRF

Embodiment 1

[0044] In this embodiment, when the UE initiates a certain service, the PCEF sends an IP-CAN session establishment instruction message to the PCRF, and the PCRF obtains the service information subscribed by the UE from the SPR, and the PCRF sets the IP-CAN session establishment response message in the IP-CAN session establishment response message. The duration of the session and / or the traffic threshold are brought to the PCEF, and the PCEF saves the threshold. When the IP-CAN session is terminated, the consumed duration and / or traffic and other usage information are reported to the PCRF in the IP-CAN session termination indication, and the PCRF sends the The SPR sends a request message to report the usage information of the IP-CAN session or the duration issued by the SPR and / or the remaining amount of traffic. The PCRF returns a response message.

Embodiment 2

[0067] In this embodiment, when the UE is in a certain business process, the PCRF needs to initiate an IP-CAN session modification process upon receiving an external trigger or due to an internal trigger, including changing the duration and / or traffic threshold of the IP-CAN session , PCRF sends the changed duration and / or traffic threshold to PCEF, and PCEF saves the updated threshold. When the session ends, PCEF sends the IP-CAN session duration and / or traffic usage information to the IP-CAN The session termination instruction is reported to the PCRF, and the PCRF reports the usage information of the IP-CAN session to the SPR, or the duration issued by the SPR and / or the remaining amount of traffic information, and the SPR stores the user subscription duration and / or the remaining amount of traffic according to the information reported by the PCRF or the remaining amount of traffic, and return a response message to the PCRF.

Abstract

A method for updating service information in a Subscriber Profile Repository (SPR) is provided and includes: when the Internet Protocol Connectivity Access Network (IP-CAN) session of a User Equipment (UE) ends, the Policy and Charging Rules Function (PCRF) reports the usage amount information or rest amount information of the IP-CAN session to the SPR; the SPR updates the current stored rest amount information of the time-scale and / or traffic subscribed by the user. The present invention enables that the actual rest amount information of the time-scale and / or traffic subscribed by the user is stored, and consequently the exact rest amount of the time-scale and / or traffic can be obtained from the SPR when the IP-CAN session is established so as to constitute the Policy and Charging Control (PCC) policy more reasonably.

Description

technical field [0001] The invention relates to the technical field of strategy and billing control in mobile communication technology, in particular to a method and system for updating service information in a user subscription database. Background technique [0002] like figure 1 As shown, the evolved packet system (EPS, Evolved Packet System) of the third generation partnership project (3GPP, 3rd Generation Partnership Project) is formed by the evolved universal mobile communication system terrestrial radio access network (E-UTRAN, Evolved Universal Terrestrial RadioAccess Network) , Mobility Management Entity (MME, Mobility Management Entity), Serving Gateway (S-GW, Serving Gateway), Packet Data Network Gateway (P-GW or PDN GW, Packet Data Network Gateway), Home Subscriber Server (HSS, Home Subscriber Server) , 3GPP Authentication Authorization and Accounting (AAA, Authentication Authorization and Accounting) server, Policy and Charging Rules Function entity (PCRF, Poli...
