Abstract

The present disclosure relates to a roaming service provision method, an IP multimedia system and a storage medium, wherein the roaming service provision method includes: setting up a new service node device in a roaming place, and the new service node device is configured with a roaming IP multimedia System (roaming IMS) service; after receiving the call signaling of the roaming VoLTE user terminal, route the call signaling to the new service node device, so as to construct the signaling containing the new service node device path, and implement call connection based on the signaling path; provide roaming IMS services for roaming VoLTE users through the newly added service node device. Through the disclosed method, without changing the existing network structure, new service node devices can be added as needed, so as to realize the diversity and flexibility of roaming services, and it can also provide convenience for users while providing Operators generate revenue.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and more specifically, to a method for providing roaming services, an IP multimedia system, and a storage medium. Background technique [0002] IMS (IP Multimedia Subsystem) is a multimedia service system built on the core network of the mobile packet domain and uses SIP (Session Initiation Protocol) as the control protocol. It is a new form of multimedia service. IMS is introduced in the UMTS (Universal Mobile Telecommunications System) R5 version formulated by 3GPP (3rd Generation Partnership Project), and uses SIP as the main signaling protocol to enable mobile operators to provide users with end-to-end IP multimedia services. [0003] As a new form of multimedia service, IMS can meet the diverse multimedia service needs of users. It is an important way to solve the convergence of mobile and fixed networks and introduce differentiated services such as triple convergence of voic...
