Problems solved by technology

[0003] The technical problem to be solved by the present invention is to aim at the above-mentioned deficiencies of the prior art, and provide a voice communication method, a network system and a user terminal to solve the problems of the prior art. Some early-market 4G terminals cannot use the IMS voice call function in 4G and 5G networks, so operators have to reserve precious spectrum resources for 2G and 3G networks and need to invest a lot of manpower and money to maintain 2G and 3G networks every year operation, resulting in a waste of network resources

Embodiment 1

[0044] This embodiment provides a voice call method, which is applied to the network side, such as figure 1 As shown, the method includes:

[0045] Step S102: If the call request of the calling terminal is received from the IP-based voice transmission VoIP (Voice over Internet Protocol) network, forward the call request of the calling terminal according to the current call preference type and / or online status of the called terminal .

[0046]It should be noted that, VoIP is a voice communication technology, and voice communication is achieved through the Internet Protocol (IP), that is, communication is performed through the Internet. VoLTE and VoNR voice are collectively referred to as IP Multimedia Subsystem IMS (IP Multimedia Subsystem) voice. IMS is proposed by the 3GPP standard organization to provide a general network architecture for IP-based multimedia services on 4G and 5G networks.

[0047] In this embodiment, in order to solve the problem that some 4G terminals o...

Embodiment 2

[0098] Such as Image 6 As shown, this embodiment provides a voice call method, which is applied to a calling terminal, and the method includes:

[0099] Step S202: performing corresponding network access according to the preferred type of the current call;

[0100] Step S204: If the preferred type of the current call is a VoIP call accessed through the VoIP network, initiate a call request to the VoIP server;

[0101] Step S206: If the preferred type of the current call is not a VoIP call accessed through the VoIP network, initiate a call request to the voice server to which the native voice belongs.

[0102] In this embodiment, if the calling terminal is part of the 4G terminal that was launched earlier, by installing the VoIP client program, it can communicate with the user terminal using IMS voice or other voice through VoIP voice. If the calling terminal supports the IMS function, by installing the VoIP client program and setting the preferred type of the current call a...

Embodiment 3

[0104] This embodiment provides a network system, which is characterized in that it includes a call management server, a VoIP server and an IMS server,

[0105] The call management server is used to receive the call request of the calling terminal from the VoIP network, and judge whether the current call preference type and / or online status of the called terminal is VoIP, and if so, forward the call request to the VoIP server; Establish a transfer between the server and the IMS server, and forward the call request to the IMS server;

[0106] The VoIP server is used to establish a VoIP voice call channel between the calling terminal and the called terminal when receiving the call request forwarded by the call management server;

[0107] The IMS server is configured to establish an IMS voice call channel with the called terminal when receiving the call request forwarded by the call management server.

Abstract

The invention provides a voice call method, a network system and a user terminal, and the method comprises the steps: forwarding a call request of a calling terminal according to the current call preference type and / or online state of a called terminal if the call request of the calling terminal is received from a VoIP network. The method, the network system and the user terminal can solve the problems that in the prior art, due to the fact that part of 4G terminals appearing in the market in the early stage cannot use the IMS voice communication function in 4G and 5G networks, operators haveto reserve precious frequency spectrum resources for 2G and 3G networks, a large amount of manpower and funds need to be invested every year to maintain operation of the 2G and 3G networks. And the problem of network resource waste is solved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a voice call method, a network system and a user terminal. Background technique [0002] Voice service is one of the main services of operators, and its realization is mainly carried out through 4G and 5G networks. However, some 4G terminals launched in the early stage do not support the 4G network voice solution VoLTE (Voice over Long-Term Evolution, long-term evolution voice bearer) or the 5G network voice solution VoNR (Voice over New Radio), so they cannot be used in 4G and 5G networks The IMS voice call function needs to fall back to 2G and 3G networks when initiating voice services. In order to meet the voice service requirements of such user terminals, operators have to reserve precious spectrum resources for 2G and 3G networks and invest a lot of manpower and funds every year to maintain the operation of 2G and 3G networks, resulting in a huge waste of net...
