METHOD AND APPARATUS FOR DETERMINING PCRF

摘要

First, correspondence relationships between subscribers and PCRFs are preset in HSS, and a same PCRF is configured to subscribers belonging to the same subscriber group. Then, the MME or AF or 3GPP AAA server sends a query message to HSS, obtains the PCRF corresponding to a certain subscriber, and then sends the PCRF information to S-GW or P-GW or ePDG. In this way, S-GW or P-GW or ePDG may send messages related to the same subscriber or the same subscriber group to the same PCRF. A network element may send to the same PCRF messages related to the same subscriber or the same subscriber group as required to be sent to the PCRFs, such that the same PCRF performs a uniform control to all related sessions of the same subscriber or the same subscriber group.

主权项

1. A method of determining PCRF in a first network server, said first network server storing information related to subscribers, the method comprising the following steps:
receiving a first request message containing identification information of a subscriber from a second network server; determining a PCRF corresponding to the subscriber based on preset correspondence relationships between subscribers and PCRFs; sending a first reply message containing identification information of the determined PCRF to said second network server; wherein the first network server pre-stores the correspondence relationships between subscribers and PCRFs.
