Problems solved by technology

[0005] The UE attaches to the visited location and requests to establish an IP channel to the visited IWF, but if the visited location does not support CSoEPS, the subsequent UE cannot perform service processing through the IP channel, that is, the established IP channel is meaningless, causing network waste of resources
[0006] Or, the UE has already registered on the IWF of the home location. If the UE switches to the visited location, the voice communication will be interrupted during the subsequent handover.

Embodiment 1

[0035] Embodiment 1 of the present invention provides a service processing method, the method comprising:

[0036] Obtain information indicating whether the visited site supports access to CSoEPS via the evolved packet domain for CS domain services;

[0037] According to the information indicating whether the visited location supports CSoEPS, determine whether the interworking function IWF serving the UE is the IWF of the visited location or the IWF of the home location;

[0038] Use the determined IWF for business processing.

[0039] Wherein, the subject of execution of the method may be UE.

[0040] Wherein, using the determined IWF for business processing includes: if it is determined that the IWF serving the UE is the IWF of the visited location, sending a registration request to the IWF of the visited location; if it is determined that the IWF serving the UE is the home When the local IWF is located, a registration request is sent to the home IWF. If it is determined ...

Embodiment 2

[0046] refer to figure 2 , Embodiment 2 of the present invention provides a service processing method. When the UE is powered on and attached to the visited site, the UE obtains information indicating whether the visited site supports CSoEPS, and determines whether the IWF serving the UE is a visiting site according to the information indicating whether the visited site supports CSoEPS. The IWF of the locality or the IWF of the attributable locality, the method includes:

[0047] A1. The UE sends a non-access stratum NAS request message to the visited MME, and the NAS request message may be an Attach Request (attach request) or a TAU Request (tracking area update request).

[0048] A2. The MME sends a NAS acceptance message to the UE. The message carries information indicating whether the visited location supports CSoEPS. The information indicating whether the visited location supports CSoEPS may be an indication information element, such as a CSoEPS Supported information ele...

Embodiment 3

[0066] refer to image 3 Embodiment 3 of the present invention provides a service processing method. The difference between this method and Embodiment 2 is that the UE also acquires information indicating whether to allow the UE to establish an LBO bearer in the visited location, and according to whether the visited location supports The CSoEPS information and the information indicating whether the UE is allowed to establish an LBO bearer in the visited location are used to determine whether the IWF serving the UE is the IWF of the visited location or the IWF of the home location. The method includes:

[0067] B1. The UE sends a NAS request message to the visited MME, and the NAS request message may be an Attach Request (attach request) or a TAU Request (tracking area update request).

[0068] B2. The MME knows whether the visited location supports CSoEPS according to the preset information, and determines whether to allow the UE to establish an LBO bearer in the visited locat...

Abstract

The invention provides a service processing method and related equipment. The method comprises the following steps: obtaining the information about whether the indicated visit place supports circuit switched domain services over evolved packet switched access (CSoEPS); and determining whether the inter working function (IWF) serving user equipment (UE) is IWF of the visit place or the home according to the information about whether the indicated visit place supports CSoEPS and adopting the determined IWF to carry out service processing. The technical scheme provided by the invention can determine whether IWF serving UE is IWF of the visit place or the home according to the information about whether the visit place supports CSoEPS.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a service processing method and related equipment. Background technique [0002] The CS (Circuit Switched, Circuit Switched) domain mainly processes voice services, and the signaling plane control entity of the CS domain is MSC (Mobile Switch Center, Mobile Switching Center) / VLR (Visitor Location Register, Visitor Location Register). In the GERAN (GSM EDGE Radio Access Network, GSM edge wireless access network) network, the wireless access network element BSS (Base Station Subsystem, base station subsystem) is connected to the MSC through the A interface, and the UTRAN (UMTS Territorial Radio AccessNetwork, universal mobile communication system The radio access network element RNC (Radio Network Controller, radio network controller) in the terrestrial radio access network) network is connected to the MSC through the Iu-CS interface. [0003] In order to meet the c...
