Subscriber number partition access method, device, equipment and medium

Abstract

Embodiments of the present invention provide a user number partition access method, device, equipment and medium. Wherein, the method includes: the S-CSCF receives the call request of the calling party sent by the P-CSCF; the S-CSCF triggers the Centrex AS to charge when the called party number of the call request is a non-emergency number, and triggers The I-CSCF sends a location information query request to the HSS, which is used to query the location information subscribed by the calling party; the S-CSCF receives the location information signed by the calling party returned by the I-CSCF; the S-CSCF sends the called party The number is transformed into the landing number of the call center corresponding to the location information signed by the calling party; S-CSCF performs number routing according to the landing number. The present invention can solve the problem of poor user experience or high cost caused by adding SBC equipment to support partition access in the prior art, improves user experience and reduces the cost of realizing partition access.

Description

technical field [0001] The present invention relates to the technical field of wireless networks, in particular to a user number partition access method, device, equipment and medium. Background technique [0002] The IP Multimedia Subsystem (IMS for short) is a brand-new multimedia service form, which can meet the requirements of more novel and more diverse multimedia services of current terminal customers. IMS can not only implement Voice over Internet Protocol (VoIP for short) services based on Internet Protocol, but also manage network resources, user resources and application resources more effectively, improve the intelligence of the network, and enable users to communicate across various networks. And use a variety of terminals to experience the integrated communication experience. [0003] IMS was first proposed by the 3rd Generation Partnership Project (3GPP) in Release 5, and its concept is very familiar to the industry. IMS is an open system architecture based o...
