Abstract: It is provided a method, comprising monitoring if an invitation to an emergency session of an anonymous user is received from an internet protocol address; checking, if the invitation is received, if an identity of a user is correlated to the internet protocol address; replacing, if the internet protocol address is correlated to the identity of the user, the identification of the anonymous user in the invitation by the identity of the user; forwarding the invitation comprising the identity of the user.

Abstract: In the area of mobile telecommunications, the performance of single radio voice call continuity (SRVCC) can be enhanced so as to provide video single radio voice call continuity (vSRVCC). Particularly, SRVCC/vSRVCC procedures can be configured for more efficient use of radio resources. A method includes receiving a query to determine in a multi-session scenario whether a last active session is a voice only session or a video session. A method also includes sending a response to the query indicating whether the last active session is the voice only session or the video session.

Abstract: A method and apparatus may include determining whether a user equipment is reachable or not. The method may also include determining whether a network should buffer downlink data. The determining whether the network should buffer the downlink data is based on stored context information or by querying an evolved Node B. The method may also include requesting a first network node to buffer the downlink data for a duration. The method may also include informing a second network node if the user equipment is determined to be unreachable. The method may also include informing the second node if the downlink data has been buffered.
