Abstract
An apparatus and method capable of creating and controlling voice bearer in reverse single radio voice call continuity comprise performing a handover request action S64 of generating a request to a mobile management entity for a handover of a mobile communication call of a user equipment from circuit switched mobile communication to packet switched mobile communication in response to an indication of required handover S61 by a radio access network controller entity; performing a notification action S62 of notifying an access transfer control function to prepare for the transfer of media to packet switched mobile communication by allocating media ports on an access transfer gateway; and performing an obtaining action S63 of obtaining the allocated media ports from the notified access transfer control function, wherein both the notification action S62 and the obtaining action S63 are performed after the indication of required handover S61 is obtained from the radio access network controller entity and before the performing of the handover request action S64, and information on the allocated media ports is included into the request S64 to the mobile management entity.
