Problems solved by technology

[0004] However, when DRA1 and DRA2 communicate through a private interface, since DRA1 only stores the correspondence between IMSI and PCRF, and the Rx interface message only carries an IP address, DRA2 needs to send the IMSI, IP The corresponding relationship between the address and PCRF is sent to DRA1, and when DRA1 and DRA2 are from different manufacturers, DRA1 and DRA2 cannot communicate through the private interface, that is, DRA2 cannot communicate the IMSI, IP address and PCRF through the private interface. The corresponding relationship between the three is sent to DRA1, so that DRA1 cannot determine the corresponding PCRF according to the Rx interface message, which leads to a low success rate of addressing PCRF

Abstract

The invention discloses an addressing method and device, relates to the field of information technology, and can improve the success rate of PCRF addressing. The method includes: the PCC includes DRA1, DRA2, PCEF, P-CSCF and at least one PCRF, the P-CSCF and the PCRF forward the Rx interface message through the DRA1, the PCEF and the PCRF forward the Gx interface message through the DRA2, first the P-CSCF is in the In the received session establishment request message, the MSISDN is obtained, and then the P-CSCF sends an Rx interface message carrying the MSISDN to DRA1, and finally DRA1 determines the corresponding MSISDN according to the received MSISDN and the correspondence between each MSISDN and each PCRF. PCRF, and send an Rx interface message to the PCRF. The present invention is suitable for realizing the addressing of PCRF.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to an addressing method and device. Background technique [0002] In the Policy and Charging Control (full English name: Policy and Charging Control, English abbreviation: PCC) architecture, the Proxy-Call Session Control Function entity (English full name: Proxy-Call Session Control Function, English abbreviation: P-CSCF) provides policy and The charging rule functional entity (full English name: Policy and Charging RulesFunction, English abbreviation: PCRF) provides business information so that PCRF can formulate corresponding policy information, and the policy and charging enforcement functional entity (full English name: Policy and Charging Enforcement Function, English PCEF for short) obtains the policy information from the PCRF to realize service control and charging. In the above process, it is necessary to ensure that the PCRF for obtaining policy information b...
