Problems solved by technology

[0008] The technical problem to be solved according to the technical solution provided by the embodiment of the present invention is to solve the problem that in the VoLTE network, when the terminal switches over the network during a voice call or a voice call, the terminal does not process the SIP signaling message from the original network and the VoLTE network is added. The resource occupation time of the network element, and the retransmission of SIP signaling by the IMS network element according to the SIP protocol, which increases the burden on the entire network

Embodiment Construction

[0038] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0039] figure 2 It is a block diagram of a method for releasing resources after a network switch occurs in a terminal in VoLTE provided by an embodiment of the present invention, as shown in figure 2 As shown, the steps include:

[0040] Step S201: After the VoLTE voice service of the terminal is switched from the original network to the current network, the IMS network detects whether the terminal has the ability to tear down the original network voice call.

[0041] Specifically, the IMS network sends a detection message to the terminal through the original network. If the IMS network receives a response message from the terminal to reply to the dete...

Abstract

The invention discloses a method and device for releasing resources in VoLTE (Voice over Long Term Evolution) after network switching occurs in a terminal and relates to the field of the VoLTE. The method comprises the steps that after VoLTE voice business of a user terminal is switched from an original network to a current network, an IMS (IP Multimedia Subsystem) network detects whether the user terminal has a capability of removing an original network voice call or not; if the IMS network detects that the user terminal has the capability of removing the original network voice call, the IMS network releases voice call resources of the original network in a mode of sending SIP (Session Initiation Protocol) signals; and if the IMS network detects that the user terminal does not have the capability of removing the original network voice call, the IMS network releases the voice call resources of the original network in a mode of not sending or not retransmitting the SIP signals. Through detection of the capability of the user terminal for removing the original network voice call, the occupation time of the voice call of the original network for resources of IMS network elements is reduced.

Description

technical field [0001] The present invention relates to the field of voice service (Voice over Long Term Evolution, VoLTE) network based on long-term evolution, and in particular to a method and device for releasing resources after network switching of a terminal in VoLTE. Background technique [0002] In the VoLTE network, when the fourth generation communication technology (The 4th Generation Mobile Communication Technology, 4G) terminal makes a voice call with the IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) network through the Packet Switching Domain (PS) network, if When the terminal undergoes a network switchover and a voice call occurs with the IMS network through the Circuit Switched Domain (CS) network, the network elements of the IMS network will tear down the original call on the PS network according to the Session Initiation Protocol (SIP) , sending a SIP signaling message such as a release call request (that is, a BYE request) or a failure response to ...
