Access domain determination method and device, equipment, medium and server

Abstract

Embodiments of the invention provide an access domain determination method and device, equipment, a medium and a server. The method comprises the following steps: receiving an INVITE message comprising identification of a called user; and by judging whether a pre-stored identification list of registered users comprises the identification of the called user, determining an access domain for voice communication of the called user, wherein the identification list of the registered users is established based on received registration information sent when a VoLTE user attaches a network successfully. The access domain determination method and device, the equipment, the medium and the server can improve accuracy of the determined access domain of the called user, and improve accuracy of the determined user phone bill type, thereby reducing billing error.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a method, device, equipment, computer-readable storage medium and service control point application server for determining an access domain. Background technique [0002] For voice calls, the current billing center uses the bill as the basis for billing, based on the voice service (Voice over LTE, VoLTE) bill of the Internet Protocol (Internet Protocol, IP) multimedia subsystem (IP Multimedia Subsystem, IMS) It adopts a different tariff policy from the second generation mobile communication (second generation, 2G) / third generation mobile communication (3rd Generation, 3G) bill. [0003] At present, different types of bills are distinguished through cell identity (Cell Identity, CELL ID) information in the bills. The VoLTE bill includes Evolved Universal Mobile Telecommunications System (Universal MobileTelecommunications System, UMTS) Terrestrial Radio Access ...

AI Technical Summary

Problems solved by technology

In the end, because the user's bill contains ECGI information, the billing center treats the user's bill as a VoLTE bill and performs billing according to the tariff policy of the VoLTE bill, resulting in incorrect billing and affecting the accuracy of billing

[0011] To sum up, when determining the location information of the called location in the prior art, it completely depends on the HSS to determine the access domain of the called user, and the HSS only determines the access domain of the called user when the called user registers on the SGSN. If the incoming domain is the CS domain, otherwise it is determined that the called user’s access domain is the PS domain, thus causing the VoLTE user to use a non-VoLTE user device as the called user and stay on the 4G network after attaching to the network. Inconsistent with the actual bill type, resulting in incorrect billing
