Embodiment 1

[0040] figure 1 It is a schematic flowchart of a management method for SRVCC handover in an embodiment of the present invention, and the method is applied to the base station side, such as figure 1 As shown, the management method of SRVCC switching in the embodiment of the present invention includes:

[0041] Step 101: Determine that the QCI1 dedicated bearer of the UE is established successfully, start a first timer and trigger the detection of the received SIP signaling.

[0042] Based on the embodiment of the present invention, in practical application, before this step, the method also includes:

[0043] According to the support capability of the core network for SRVCC, the first SIP signaling is pre-configured, and the first timer is pre-set; If the SRVCC handover of the UE is not supported, the first SIP signaling can be configured as the SIP signaling of the 180 ring; the first SIP signaling indicates that SRVCC handover is allowed, that is, the first SIP signaling is...

Embodiment 2

[0054] figure 2 It is a schematic flow diagram of a management method for SRVCC handover in an embodiment of the present invention. The method is applied to the base station side. In this embodiment, the SIP signaling between the IMS and the UE has been encrypted, such as figure 2 As shown, the management method of SRVCC switching in the embodiment of the present invention includes:

[0055] Step 201: Pre-configure first SIP signaling and a first timer.

[0056] Here, in actual implementation, the first SIP signaling is pre-configured according to the core network's ability to support SRVCC. For example, within a period of time between the UE's QCI1 dedicated bearer being successfully established and the SIP signaling 180 ringing, the core network does not To support SRVCC switching of the UE, the first SIP signaling can be configured as the SIP signaling of the 180 ring; the first SIP signaling indicates that SRVCC switching is allowed, that is, the first SIP signaling is ...

Embodiment 3

[0069] image 3 It is a schematic flow diagram of a management method for SRVCC handover in an embodiment of the present invention. The method is applied to the base station side. In this embodiment, the SIP signaling between the IMS and the UE is not encrypted, such as image 3 As shown, the management method of SRVCC switching in the embodiment of the present invention includes:

[0070] Step 301: Pre-configure first SIP signaling and a first timer.

[0071] Here, in actual implementation, the first SIP signaling is pre-configured according to the core network's ability to support SRVCC. For example, within a period of time between the UE's QCI1 dedicated bearer being successfully established and the SIP signaling 180 ringing, the core network does not To support SRVCC switching of the UE, the first SIP signaling can be configured as the SIP signaling of the 180 ring; the first SIP signaling indicates that SRVCC switching is allowed, that is, the first SIP signaling is dete...

Abstract

The invention discloses a single-channel voice call continuity (SRVCC) switching management method and apparatus. The method comprises the steps of determining that a QCI1 of a terminal (UE) is established successfully, starting a first timer, and triggering detection of a received session initiation protocol (SIP) signaling; prohibiting execution of SRVCC switching of the UE when it is determinedthat the first timer is not overtime, the first SIP signaling is not detected before the first timer is overtime, wherein the first SIP signaling indicates that SRVCC switching is allowed; and allowing the execution of the SRVCC switching of the UE, for example, sending a radio resource control (RRC) connection reconfiguration signaling to the terminal, when it is determined that the first timeris overtime, and the first SIP signaling is not detected before the first timer is overtime, or determining that the first timer is not overtime, and the first SIP signaling is detected before the first timer is overtime.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a management method and device for Single Radio Voice Call Continuity (SRVCC, Single Radio Voice Call Continuity) switching. Background technique [0002] SRVCC is a VoLTE (Voice over LTE) voice service continuity solution. How to ensure the continuity of the voice call when moving between the two, that is, to ensure the smooth switching between the VoIP voice controlled by the IP Multimedia Subsystem (IMS, IP Multimedia Subsystem) and the CS domain voice of the single-radio UE. [0003] Since the various modules that perform SRVCC handover need to communicate with each other, and the core network does not support SRVCC handover during a period of time during a VoLTE call, if the base station determines that the UE performs SRVCC handover during a period of time during a VoLTE call, it will As a result, the call cannot be connected, which seriously affects...
