Abstract: There is proposed a method and corresponding apparatuses allowing a change from a packet switched communication domain to a circuit switched communication domain. When a user equipment as a connection terminating point receives a connection initialization message with a media flow, such as audio, which cannot be delivered by the packet switched access, it sends a specific response rejecting the connection via the packet switched access to an application server for service centralization and continuity. In the application server, it is checked whether several conditions are met in order to determine whether the communication connection comprising the media flow is allowed to be changed to the circuit switched domain. If yes, the communication connection is changed from the packet switched communication domain to the circuit switched communication domain.

Abstract: Systems, methods, apparatuses, and computer program products for data storage (DS) function selection are provided. One method includes obtaining, from a network node, an address of a DS function that contains user equipment (UE) context information for at least one UE. The method may further include accessing, by a client, the DS function to register for the UE context information.

Abstract: A method, apparatus and computer program product are provided in accordance with example embodiments in order to provide methods, apparatuses, and/or systems that reduce and/or eliminate network inefficiencies caused by the persistence of user-equipment-specific associations with network interfaces and elements, including but not limited to user-equipment-specific associations on at least N2. In some example implementations, an AMF may assign a temporary ID containing particularized identification information to a UE in a manner that allows for selection by a (R)AN of a AMF and that enables an AMF to process an N1/N2 transaction, such as may occur when a UE enters an idle mode and/or transitions from an idle mode to a connected mode.

Abstract: A server receives a call request for a mission critical, push to talk (MCPTT) call. In response to receiving the call request, the server accesses a mapping of an MCPTT identifier of a user equipment with an interworking identifier that is formed according to an address format implemented in Global System for Mobile communications (GSM) for Railways (GSM-R). The server then forwards the call request from the server based on the mapping. In some cases, the MCPTT identifier is a uniform resource identifier (URI) and the interworking identifier is represented in an e164 format.
