Method and apparatus for facilitating communication session continuity
Abstract:
A method and apparatus are provided for facilitating communication session continuity. A method may include receiving, at a terminal, an identifier associated with an EATF (emergency access transfer function). The method may further include determining that the terminal has undergone a reverse SRVCC (Single Radio Voice Call Continuity) handover from a circuit switched access to a packet switched access while engaged in an active emergency session. The method may additionally include, responsive to the determination, using the identifier to set up an emergency session transfer request to the EATF to cause creation of a bearer for the emergency session on the packet switched access. A corresponding apparatus is also provided.
