Embodiment 1

[0096] Embodiment 1 is a mobility management entity 2 provided by an embodiment of the present invention. The mobility management entity 2 is applied to an SRVCC handover system, such as figure 2 As shown, the mobility management entity includes:

[0097] The receiving unit 21 is configured to receive a first handover request message sent by the base station, where the single wireless voice call continuity SRVCC handover indication contained in the first handover request message is packet switching PS and circuit switching CS;

[0098] The sending unit 22 is configured to send a handover preparation failure message to the base station when the PS handover preparation requested by the first handover request message fails, and the handover preparation failure message indicates that only circuit switching CS is required;

[0099] The receiving unit 21 is further configured to receive a second handover request sent by the base station, where the SRVCC handover indication included...

Embodiment 2

[0131] Embodiment 2 is a base station 3 provided by an embodiment of the present invention, and the base station 3 is applied to an SRVCC handover system such as image 3 As shown, the base station 3 includes:

[0132] The sending unit 31 is configured to send a first handover request message to a mobility management entity, where the single radio voice call continuity SRVCC handover indication contained in the first handover request message is packet switched PS and circuit switched CS;

[0133] The receiving unit 32 is configured to receive a handover preparation failure message sent by the mobility management entity, where the handover preparation failure message indicates that only circuit switching CS is required;

[0134] The sending unit 31 is further configured to send a second handover request to the mobility management entity, where the SRVCC handover indication included in the second handover request is only CS.

[0135] Optionally, the handover preparation failure...

Embodiment 3

[0141] Embodiment 3 is a handover method provided by an embodiment of the present invention, which is applied to a mobility management entity, such as Figure 4 As shown, the method includes:

[0142] 401. A mobility management entity receives a first handover request message sent by a base station, where the SRVCC handover indication included in the first handover request message is packet switched PS and circuit switched CS.

[0143] 402. When the PS handover preparation requested by the first handover request message fails, the mobility management entity sends a handover preparation failure message to the base station, where the handover preparation failure message indicates that only CS is required.

[0144] 403. The mobility management entity receives the second handover request sent by the base station, where the SRVCC handover indication included in the second handover request is CS only.

[0145] The embodiment of the present invention provides a handover method. Afte...

Abstract

The invention provides a switching method, a base station, and a mobile management body, which belong to the technical field of wireless communication. The method comprises the steps of receiving a first switching requirement message sent by the base station, wherein the first switching requirement message includes a single wireless voice communication continuity SRVCC switching instruction, divided into a grouping switching PS and a circuit switching CS; sending the message of switching failure when the PS switching preparation required by the first switching requirement message fails (the message of switching preparation failure only requires circuit switching CS); receiving a second switching requirement sent by the base station (the SRVCC switching instruction included by the second switching requirement is only CS). The invention is advantageous in that when the mobile management body determines that the data and voice switching failed, the base station resend a voice single switching requirement, and thereby the mobile management body can conduct voice switching, and communication interruption due to the failure of double switching of data and voice can be prevented.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a switching method, a base station and a mobility management entity. Background technique [0002] In the existing technology, since the initial deployment of LTE / EPC (Long Term Evolution, Long Term Evolution / Evolved Packet Core, evolved packet core) is gradually implemented from point to area through hotspot coverage, traditional CS (Circuit Switch, circuit switching) network to make up for the lack of signal coverage in the initial stage of LTE / EPC deployment. At this time, it is necessary to provide a handover method based on SRVCC (Single Radio Voice Call Continuity) technology to realize the handover between the traditional CS network and the LTE network, so that users cannot perceive LTE and CS. Voice interruption when switching between networks. [0003] The prior art provides a SRVCC handover method, that is, the RNC (Radio Network Controller, Radio Netwo...
