Embodiment 1

[0057] Figure 1B It shows a schematic flowchart of the method for solving the problem of incorrectly generating roaming charging during eSRVCC handover provided by Embodiment 1 of the present invention.

[0058] refer to Figure 1B The method for solving the problem of roaming billing caused by mistake during eSRVCC switching proposed by Embodiment 1 of the present invention specifically includes the following steps:

[0059] 101. The eMSC receives a handover request sent by a base station for switching a UE from VoLTE to GSM.

[0060] In this step, the switching request includes: user identification and switching type information.

[0061] For example, the handover request is a handover request sent by the MME to the eMSC, specifically a handover request from the eSRVCC packet domain to the circuit domain, and the handover request includes: eSRVCC handover type information and a user identifier.

[0062] 102. When the user ID is a non-local ID and the handover type inform...

Embodiment 2

[0075] In Embodiment 2 of the present invention, all the steps of the above-mentioned Embodiment 1 are included, wherein, the step 102 of the method of the above-mentioned Embodiment 1 also includes sub-steps not shown in the following figures, and the step 102 includes:

[0076] 1021. When the handover type information is the eSRVCC handover type, the eMSC sends a location acquisition request to the HSS, where the location acquisition request includes: a user identifier.

[0077] In this step, when the handover type information in the handover request sent by the MME is the eSRVCC handover type, the eMSC sends a MAP layer message location acquisition request to the HSS (Home Subscriber Server, Home Subscriber Server).

[0078] 1022. The eMSC receives the attribution of the user ID sent by the HSS, and the attribution of the user ID is found by the HSS according to the location acquisition request.

[0079] In this step, the HSS determines the attribution of the user ID accord...

Embodiment 3

[0084] Local communication service on the existing network, that is, users can only register under the network of the city they belong to and enjoy the services provided by the local equipment. The roaming restriction for users of the local communication service is implemented based on the list of roaming switches allowed by the user in the HSS. Users who have subscribed to the local communication service only have a list of local exchanges in the HSS. Therefore, when a local communication user undergoes eSRVCC handover and performs location update, since the list of switches allowed to be registered by the user in the HSS does not have the switch address of the eMSC in the provincial capital city, the registration fails, resulting in subsequent service failure.

[0085] Existing technical solutions and defects:

[0086] In the HSS, add the address of the eMSC to the roaming allowed list of the local communication user. This solution can solve the problem of unsuccessful loc...

Abstract

The invention provides a method for solving roaming billing generated by mistake during eSRVCC (enhancement Single Radio Voice Call Continuity) switching and an eMSC. The method comprises the following steps: receiving a switch request sent by a base station for switching UE from VoLTE (Voice over LTE) to GSM by the eMSC, wherein the switch request comprises a user identifier and switching type information; acquiring a proxy switch address which is different from an own switch address of the eMSC by the eMSC when the user identifier is a non-local identifier and the switching type informationis an eSRVCC switching type; after completing the circuit domain resource reservation by the eMSC, sending a switching completion notification to an MME; generating a switching call ticket by the eMSCaccording to a corresponding time point of sending the switching completion notification, wherein the switch address in the switching call ticket is the proxy switch address; and sending the switching call ticket to a BOSS system by the eMSC, so that the BOSS system determines that the switching call ticket does not generate roaming charges according to the proxy switch address in the call ticket. The method of the invention can quickly and efficiently solve the problem that the roaming bill generated by mistake cannot be sorted when the eSRVCC is switched.

Description

technical field [0001] The invention relates to a communication technology, in particular to a method and an eMSC for solving roaming billing generated by mistake when eSRVCC is switched. Background technique [0002] VoLTE (Voice over LTE) is defined by 3GPP standard: LTE voice solution based on IMS network. Through the IMS network, mobile operators can not only seamlessly inherit traditional voice and short message services, but also integrate voice calls with rich enhanced functions to provide diversified services. [0003] VoLTE is a voice solution that uses LTE network as service access and IMS network to realize service control, such as Figure 1A Shown: [0004] 1) Service access: The LTE network is an all-IP network without a CS domain, and both data services and voice multimedia services are carried on LTE. [0005] 2) Service control: The EPC network does not have call control functions for voice and multimedia services, and needs to provide service control funct...
