Abstract
A method and device for realizing the voice continuity of session are disclosed. Said method includes: when the handover between source network and destination network is needed to perform the technology scheme which realizes the voice continuity on the bearer level is adopted; if the packet domain of destination network does not support VoIP the signaling bearer of session is switched to the packet domain of destination network the voice bearer of session is switched to the circuit domain of destination network and the following signaling which is transferred from source network to the circuit domain of destination network is processed by employing PCC architecture; the voice continuity is transparent for service network during the whole procedure. Said method guarantees both the voice service continuity of session and the normal using of other services in service network without upgrading and rebuilding the service network. When the handover from destination network to source network needs to be performed by employing the PS handover from destination network to source network said method triggers the handover which switches the voice data and signaling of following session to the source network.
