Problems solved by technology

[0016] 2) When the VCC user terminal is registered in the IMS domain, but calls through CS, only Immediate Messaging can be used at this time
[0017] 3) If the IMS domain is not registered and the call is made through the CS, the IMS Message service cannot be used at this time, and other methods must be used for message communication, such as short messages
[0019] Currently there is no method to obtain the service status of the Voice Call Continuity VCC service in IMS, which can solve the above problems

Abstract

A method of obtaining operation state of voice calling continuity operation, when network entity needs operation state information of voice calling continuity operation VCC, it builds subscription request message, that is SUBSCRIBE message, and it is sent to VCC application server, the message at least takes network entity mark of subscriber, mark of subscribed resource and VCC operation affair package; when the VCC application server receives the SUBSCRIBE message, the state of trigger is returned, current VCC operation information of subscribed resource is sent to the network entity as subscriber via NOTIFY message; the network entity receives the NOTIFY message, obtains VCC operation state information needed, process as corresponding operation. The invention is applied in network entities to obtain operation state of VCC conversation for operation.

Description

technical field [0001] The present invention relates to an IP multimedia subsystem (IP Multimedia Core Network Subsystem, IMS) voice call continuity service (Voice Call Continuity, VCC), in particular to a method for acquiring the service status of the IP multimedia subsystem voice call continuity service. Background technique [0002] Using IP Multimedia Core Network Subsystem (IMS) technology, VoIP (Voice over Internet Protocol) services can be provided on packet networks such as Wireless Local Area Networks (WLAN). Utilize this technology, can offer most business on the circuit domain (Circuit Switched Domain) such as GSM to the user in the area that has wireless coverage such as WLAN. [0003] Voice call continuity service (Voice Call Continuity, VCC) service is organized by 3GPP (3 rd Generation Partnership Project) proposes a service that can realize seamless switching between voice communication in the CS domain and voice communication in the WLAN domain based on th...
