Embodiment Construction

[0056] In order to enable those skilled in the art to better understand the technical solution of the present invention, the communication method for porting the number to the network, the calling side service control point server and the called side service control point server of the present invention will be explained below in conjunction with the accompanying drawings and specific embodiments described in further detail.

[0057] The present invention takes into account the characteristics of the group users and the characteristics of the users after porting the number to the network, and solves the problem that the VoLTE user is the called party and another group network user is the calling party in the group user's number portability transfer service, ensuring that the group users After porting out and registering in the IMS domain, it can communicate with users of another group network registered in other domains (such as IMS domain, CS domain), so as to ensure the norma...

Abstract

The invention belongs to the technical field of communication networks, and relates to a number portability communication method, and a calling side / called side service control point server. The method comprises the following steps: receiving a call invitation message sent by a calling side call session control function entity; judging whether a calling number corresponding to a first terminal anda called number corresponding to a second terminal belong to the same group user; if the calling number and the called number do not belong to the same group user, performing, by a calling side service control point server, domain selection on a called user, and querying the location information of the called user; sending, by the calling side service control point server, the call invitation message to the calling side call session control function entity according to the location information of the called user, so that the calling side call session control function entity and a telephone number mapping server / domain name system initiate a query request of querying a name authority pointer record of the called number; and routing, by the calling side call session control function entity,the call to an IMS domain and mutual communication network elements of other networks according to a called domain name.

Description

technical field [0001] The invention belongs to the technical field of communication networks, and in particular relates to a communication method for porting a number to a network, a service control point server at a calling side, and a service control point server at a called side. Background technique [0002] With the development of science and technology, terminals (such as mobile phones, etc.) have become a necessity in people's lives. And as people's quality of life continues to improve, they have higher requirements for consumer experience. [0003] VoLTE (Voice over LTE, LTE network direct transmission) is a voice service in the data domain of the LTE network based on IMS (IP Multimedia Subsystem, IP Multimedia Subsystem). IMS is composed of all functional entities that can provide multimedia services, enabling operators to provide their users with multimedia services based on Internet applications, services and protocols. The LTE network is an all-IP network, and...
