Example Embodiment

[0042] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the invention are shown in the accompanying drawings, it should be understood that the invention can be implemented in various forms and should not be limited by the embodiments set forth herein.

[0043] The embodiment of the invention is mainly applied to 5g communication network based on service-based architecture (SBA). At present, IMS network adopts a hierarchical topology network structure, in which there are many network element nodes, the network structure is complex, the levels between nodes are staggered, the interaction and docking are complex, and the functions of each network element are centralized, the expansion is difficult, and the expansibility is poor, which can not meet some personalized needs. Different from the previous 4G network structure, 5g core network adopts a more flat implementation...

Abstract

The embodiment of the invention relates to the technical field of mobile communication, and discloses a voice call method, device and system and a user terminal, which are applied to a voice call system based on a servitization architecture, and the method comprises the following steps: a first VOCSCF receives a call invitation message sent by calling UE through a first VOSBCF; the call invitation message comprises called user information; the first VOCSCF notifies a second VOCSCF of the call invitation message according to the called user information, and the second VOCSCF obtains the voice service related information of the called user from the VOASF according to the called user information; the second VOCSCF sends a call invitation message to the called UE through the second VOSBCF according to the voice service related information, and notifies the first VOCSCF after receiving a call response message of the called UE forwarded by the second VOSBCF; and after receiving the call response message, the first VOCSCF sends the call response message to the calling UE through the first VOSBCF, and establishes a voice call. Through the above mode, the voice communication quality is improved, the communication time delay is reduced, and the user service experience is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mobile communication, and in particular to a voice calling method, device, system and user terminal. Background technique [0002] The IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) voice call scheme under the fourth-generation mobile communication technology (4G) is that after the data message is output from the 4G air interface, it first enters the IMS access point (APN, Access PointName), Realize functions such as voice call registration and configuration under the IMS network, and finally call the VoLTE (Voice over Long-Term Evolution, long-term evolution voice bearer) voice core module to complete the voice interaction. At present, the fifth-generation mobile communication technology (5G) inherits the voice call architecture of 4G, and enters the IMS APN after being output by the 5G air interface, and completes the same steps as the 4G voice call solution. [0003] ...
