Dynamic handover method and system on basis of service broker

Based on dynamic switching method and system service agent, the method comprising: MSC / SSP triggers the call to the Service Broker, Service Broker according to the corresponding priority triggering several service users subscription respectively corresponding SCP sequentially trigger; when the service Broker whether triggered when the last set of SCP, before the determination of all the triggered functions none SCP service trigger, if it is, then the call signaling MSC / SSP to the last issued a Handover SCP; MSC / SSP and The last set of SCP directly signaling interaction, Service Broker to exit the current dialog. The present invention belongs to the technical field of mobile communications, according to the corresponding call flow, effectively reduce the signaling processing Service Broker reduce complexity and unnecessary overhead signaling link.
