Embodiment 1

[0048] An embodiment of the present invention provides a method for triggering an SRVCC process, such as figure 1 As shown, it can be implemented by MME, wherein the method triggered by the SRVCC process specifically includes the following steps:

[0049] 101. The MME receives a CSFB access request sent by a UE.

[0050] Wherein, the above-mentioned Circuit Switched Fallback (English: Circuit Switched Fallback, CSFB for short) access request includes a UE capability (English: capability) parameter, and the UE capability parameter is used to indicate that the UE has the SRVCC capability. The CSFB access request is used to trigger the CSFB procedure. Specifically, the aforementioned CSFB access request may be an Extended Service Request (English: Extended Service Request, ESR for short) message.

[0051] 102. The MME obtains the STN-SR in the user subscription information of the UE.

[0052] Wherein, the above-mentioned SRVCC session switching number (English: STN-SR) indicat...

Embodiment 2

[0069] An embodiment of the present invention provides a method for triggering an SRVCC process, such as figure 2 As shown, it can be implemented by the base station, and the SRVCC process triggering method specifically includes the following steps:

[0070] 201. The base station receives a handover request message sent by an MME according to a CSFB access request.

[0071] Wherein, the above handover request message includes the capability parameter of the UE and the STN-SR of the UE. Specifically, the above UE capability parameter is used to indicate that the UE has SRVCC capability; and the above STN-SR indicates that the MME supports SRVCC and the MME opens SRVCC to the UE.

[0072] 202. When the base station determines that the current network environment of the UE is suitable for triggering the SRVCC process according to the measurement report reported by the UE, the base station triggers the SRVCC process according to the capability parameter of the UE contained in th...

Embodiment 3

[0077] The following will exemplarily introduce the method for triggering the SRVCC process provided by the embodiment of the present invention in a specific scenario. For descriptions of technical terms, concepts, etc. related to the above-mentioned embodiments in the following embodiments, reference may be made to the above-mentioned embodiments. This embodiment is mainly aimed at the process that the UE needs to continue to execute the CSFB process after the SRVCC process is triggered during the CSFB process.

[0078] Such as image 3 As shown, the specific SRVCC process triggering method is as follows.

[0079] 301. The MME receives the Extended Service Request message sent by the UE.

[0080] Wherein, the above-mentioned ESR message is used to trigger the CSFB procedure, and the ESR message includes the capability parameter of the UE. The above UE capability parameter is used to indicate that the UE has SRVCC capability.

[0081] 302. If the MME does not include the s...

Abstract

The embodiment of the invention provides an SRVCC process triggering method, a mobile management entity and a base station, relates to the field of communication and solves a problem in the existing CSFB process that voice resources cannot be managed in a unified way. The concrete scheme is that an MME receives a CSFB access request sent by a UE; the MME acquires an SRVCC session switching number STN-SR in user subscription information of the UE; after the MME receives the CSFB access request, a switching request message is sent to the base station; the switching request message comprises the ability parameter of the UE and the STN-SR of the UE; and after the MME receives the switching request message fed back by the base station, SRVCC business indication is sent to a mobile switching center MSC according to indication of the switching request message so that the MSC is enabled to execute the SRVCC process according to the SRVCC business indication. The SRVCC process triggering method is applied to the SRVCC process.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for triggering an SRVCC process, a mobility management entity and a base station. Background technique [0002] In a Long Term Evolution (English: Long Term Evolution, LTE for short) network, when a user equipment (English: User Equipment, UE for short) makes a voice call, there are usually two ways to implement the voice call. Among them, one is implemented by circuit domain fallback (English: Circuit Switched Fallback, referred to as CSFB) technology, that is, the UE will fall back from the fourth generation mobile communication technology (English: the 4Generation Mobile Communication Technology, referred to as 4G) network to the second generation In mobile communication technology (English: Second Generation, referred to as 2G) / third generation mobile communication technology (English: 3rd Generation, referred to as 3G) network, use 2G / 3G network to realize voice service; t...
