Problems solved by technology

[0040] It can be seen that in figure 2 In the anchoring process shown, when the outgoing MGCF is different from the incoming MGCF, the signaling flow needs to cross two MGCFs in the entire anchoring process, thus causing detours in the signaling flow and increasing end-to-end calls delay, while reducing the efficiency of complaint handling and fault location

[0070] The embodiment of the present invention discloses an optimization method for calling a VoLTE user, and the method is suitable for optimizing an anchoring process when calling a VoLTE user located in a CS domain.

[0071] image 3 It is a flow chart of an embodiment of the optimization method for calling a VoLTE user in the present invention, such as image 3 As shown, the process includes:

[0072] Step 300: When the called home GMSC routes the call to the incoming MGCF, the called home GMSC selects the incoming MGCF, and the incoming MGCF sends its own identification information to the I-CSCF.

[0073]This step specifically includes: the called home GMSC selects one MGCF as an incoming MGCF among n MGCFs in the called home;

[0074] When the incoming MGCF sends the message to the I-CSCF in the IMS domain according to the default route, the incoming MGCF sends its own identification information to the I-CSCF; Feature information of other MGCFs among the n MGCFs in th...

Abstract

The embodiments of the invention disclose an optimization method for calling a VoLTE user. The method includes the following steps: in the process when a called business of the VoLTE user is anchored to an IP multimedia sub-system (IMS), if a service-call session control function entity (S-CSCF) receives a signally which is transmitted by an inquiry-call session control function entity (I-CSCF), the S-CSCF recording the identification information of an invited media gateway control function entity (MGCF) carried in the signaling which is transmitted by the I-CSCF; when the S-CSCF acquires the CS domain routing number (CSRN) of the called subscriber, the S-CSCF, based on the recorded identification information of the invited MGCF, selecting the MGCF as an uninvited the MGCF. The embodiments of the invention also disclose an optimization apparatus and system for calling a VoLTE user.

Description

technical field [0001] The present invention relates to VoLTE (Voice over LTE) technology of Long Term Evolution (LTE, Long Term Evolution), in particular to an optimization method, device and system for calling VoLTE users. Background technique [0002] The LTE voice solution is mainly based on VoLTE. When VoLTE users are covered by Time Division Long-Term Evolution (TD-LTE, TimeDivision-LTE) network wireless coverage, they can access IP A multimedia subsystem (IP Multimedia Subsystem, IMS) core network and an IMS service platform; at this time, the IMS core network completes VoLTE routing and call control, and the IMS service platform implements VoLTE service processing. When VoLTE users are not covered by TD-LTE network and not covered by 2G / Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) network, they can access via 2G or TD-SCDMA wireless network Core network circuit switched (Circuit Switched,...
