Problems solved by technology

[0048] Considering that the CAMEL-based network-side routing control scheme is limited by whether the calling party’s visiting circuit domain network supports CAMEL capabilities, the CAMEL scheme itself has relatively mature applications; while the terminal-side routing control scheme based on USSD / SIP Notify / Prefix Although the solution is not limited by the ability of the calling party to visit the circuit domain network, it is a brand new solution and has not yet been applied.
[0049] Therefore, it is hoped that there will be a solution that integrates the two schemes, that is, use the CAMEL-based network-side routing control scheme when the calling-side circuit domain network supports CAMEL, but only when the calling-side circuit domain network does not support CAMEL In the case of using USSD / SIPNotify / Prefix-based terminal side routing control scheme, but currently there is no corresponding scheme to meet this requirement

Embodiment Construction

[0097] The present invention is mainly applied in the static anchor point scheme of the voice service continuity service. When it is necessary to anchor the call initiated by the circuit domain user as the calling party in the gsmSCF and / or AS with the CCCF function, in order to be able to integrate different routes Control mode, which controls the way the user terminal initiates a call, so that the user terminal can determine the way to initiate a call according to the routing control mode supported by the current network side (that is, VLR), and initiate the establishment of an initial call, so as to flexibly support the corresponding Routing control mode.

[0098] That is to say, the core of the present invention is to provide a solution for fusion processing of the USSD / SIP Notify / Prefix-based terminal-side routing control scheme and the CAMEL-based network-side routing control scheme, that is, in the calling side circuit When the domain network supports CAMEL, use the CAM...

Abstract

Present invention relates to a method and system for establishing calling in continuance voice service. It contains user terminal notifying registration state of application server in circuit domain, application server determining user terminal mode according to user terminal current registered circuit domain network supported route control pattern information, notifying user terminal, when said user terminal originating circuit domain calling, originating calling according to notified originating calling mode. Said invention can maximized utilize dialing side circuit domain CAMEL proceeding initial call establishment and anchoring calling in gsmSCF with CCCF function utilizing USSD Notify / Prefix scheme as CAMEL supply, avoiding calling static anchoring failing due to dialing side circuit CAMEL scarce capacity.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and system for establishing an initial call in a voice service continuity service. Background technique [0002] From the 3GPP R5 (3rd Generation Partnership Project, the third generation mobile communication standardization partner project) stage, the UMTS (Universal Mobile Telecommunications System) core network is divided into CS (Circuit Switching), PS (Packet Switching) and IMS (IP Multimedia Subsystem) ) three subsystems. [0003] The CS domain (Circuit Switched Domain, Circuit Switched Domain) is used to provide the connection of the circuit service to the user. The CS domain mainly includes: MSC (MSC Server / CS-MGW, MobileSwitch Center Server / CS-Media GateWay, mobile switching center server / circuit domain-media gateway), GMSC (Gateway MSC, gateway mobile switching center) and IWF (InterWorKing Function , interworking function). Among them, the MSC...
