Abstract

The invention discloses a method and device for synchronizing supplementary service information of an IMS domain and a CS domain. The device for synchronizing supplementary service information of the IMS domain and the CS domain comprises a first synchronization module and a second synchronization module, wherein the second synchronization module is used for obtaining the supplementary service information of the CS domain from a home location register of the CS domain and is used for transmitting the supplementary service information of the CS domain to a first synchronization module; the first synchronization module is used for transmitting supplementary service configuration request information to an IMS domain service configuration proxy gateway according to the supplementary service information of the CS domain in order to make the service configuration proxy gateway of the IMS domain configure the supplementary service to a multimedia telephone service network element based on the IMS so as to realize a fact that the supplementary service information is synchronized from the CS domain to the IMS domain. The method and device for synchronizing supplementary service information of the IMS domain and the CS domain have no reconstruction requirements for current network devices, totally accord with network standard flows and only play roles of protocol transition and adaption. The method and device of the invention are easy to realize and low in realization cost.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and a device for synchronizing supplementary service information in an IMS domain and a CS domain. Background technique [0002] In 2 / 3G or 4G mobile communications, due to the different networks carrying voice services, the network devices for supplementary service configuration and implementation of supplementary services are independent; the same user uses and obtains the same service perception in different 2 / 3G or 4G voice service networks and service experience, it is necessary to synchronize supplementary service information in the IMS (IP Multimedia Subsystem, IP multimedia subsystem, where IP refers to the Internet Protocol network protocol) domain and the CS domain (Circuit Switched Domain, circuit switched domain). [0003] It is required to insert a 4G card into a VoLTE (Voice over LTE, IMS-based voice service, where LTE means Long Term Evolution, long-ter...
