Methods and nodes to select a target core network in order to perform a handover of a voice session of a terminal

Method for selecting a core network (110, 210) of destination of a network (100, 200) communications for a handover a voice session of a terminal (118, 218) from a network (104, 204) radio access packet switched, home, network (100, 200) communications to a network (262) of radio access network destination (100, 200) communications, wherein the voice session is anchored in Multimedia Subsystem Internet Protocol network (100, 200) communication, and wherein the core network (110, 210) selected destination comprises a switched domain circuits is associated with the network (262 ) radio access destination and supports continuity of voice sessions that allows a transfer of the voice session from the network (104, 204) radio access packet switched, source, to the network (262) radio access destination, where the network (262) radio access destination is associated with a network identification of the core network (110, 210) of destination, being executed method by a node (112, 212, 612) forming part of the network (104, 204) radio access source, the method comprising: - receiving (126, 226) a network identification of at least one core network (110, 210) associated target to at least one network (262 ) radio access destination, wherein identifying redindica support for continuity of voice sessions, and - selecting (138, 238) the core network (110, 210) target based on support indicated continuity sessions voice indicated by the received network identification.
