Embodiment Construction
[0044] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following describes the communication method of the present invention related to number portability transfer, the calling service control point, and the calling media gateway control functional entity in conjunction with the accompanying drawings and specific embodiments. And the called service control point is further described in detail.
[0045] This embodiment provides a communication method for porting a number to a network, which avoids the technical disadvantages of poor communication effect and high cost in the prior art, and realizes the technical effect of saving costs under the premise of ensuring normal communication of users.
[0046] The communication method of porting the number to the network is suitable for when the first terminal registered in the CS domain calls the second terminal registered in the CS domain after the number porting, w...

The invention belongs to the field of communication networks, and relates to a communication method for porting a number to a network, a calling service control point, a calling media gateway control function entity and a called service control point. Including: receiving the call invitation message sent by the mobile switching center, the call invitation message is sent by the first terminal to the mobile switching center; judging whether the calling number corresponding to the first terminal and the called number corresponding to the second terminal belong to the same group user, The second terminal is a VoLTE user; if the calling number and the called number do not belong to the same group of users, the call invitation message is forwarded to the mobile switching center for the mobile switching center to interact with the called multimedia telephony application server. In the IMS domain, the first indication message is sent to the calling media gateway control function entity. After the VoLTE users in the WVPN group users are ported out, they can communicate with the circuit domain users of another WVPN group network registered in the CS domain when they register in the CS domain.
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 calling service control point, a calling media gateway control function entity and a called service control point. 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, voice carried by LTE network) is a voice service in the data domain of 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 netwo...
