<p>The present invention provides with a method of distinguishing a plurality of calling UEs sharing a PUID in a calling S-CSCF of IMS network and the device thereof. When a calling UE using a shared PUID in the calling-party network requests to establish a session with some called UE in the called-party network, the calling S-CSCF adds a extension identification corresponding to the calling UE into the session request message from the calling UE and sends the session request message with the extension identification added therein to the called UE in the called-party network, such that the called UE may realize which one is the actual calling UE according to the extension identification in the session request message and the shared PUID used by the calling UE. Therefore, after completion of such session, the called UE may re-establish a session with the calling UE according to the extension identification of the calling UE and the shared PUID thereof.</p> |
