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.

Abstract: An example apparatus is caused to receive a message inviting a user equipment (UE) to participate in an emergency communication session with an originating node, where the user equipment is registered with an Internet Protocol Multimedia Subsystem (IMS). The apparatus is caused to identify a type of registration of the UE with the IMS, and select a transfer function of the IMS to anchor the emergency communication session based on the identified type of registration of the user equipment with the IMS. The transfer function may be a domain transfer function or emergency access transfer function of the IMS. The apparatus is also caused to prepare the message for transmission to the selected transfer function to thereby enable the selected transfer function to anchor the emergency communication session and further communicate with one or more other components of the IMS to establish the emergency communication session with the user equipment.

Abstract: Various methods for implementing a wait period for single radio continuity transfers are provided. One example method includes obtaining a timer value, where the timer value is based on a communications delay to a far end device. The communications delay to the far end device may be determined during session establishment with the far end device. The example method also includes implementing a wait period for a duration of the timer value, and, in response to completion of the wait period, triggering a single radio continuity network transfer. Similar and related example methods and example apparatuses are also provided.
