Abstract
The present invention relates to a solution for handling handover of connections for a user equipment from a packet switch network to a circuit switched network. This is provided as a method implemented in a node and system. The method is provided in a telecommunications network (100) connecting user equipment, i.e. UE, (101) communicating wirelessly (111) with the network. The method comprising steps of detecting (301) that handover is required from a packet switched, i.e. PS, based network (102) to a circuit switched, i.e. CS, based network (103), initiating (302) in a source mobility management node (104) a single radio voice call continuity, i.e. SVRCC, initiating (303) a PS to PS handover for non-voice components with information about voice related parameters and a PS to CS handover indicator, executing (304) hand over, sending (305) an update to a serving gateway, i.e. SGW, (107) from a target mobility management node (105) with non-voice related parameters and the PS to CS handover indicator, forwarding (306) the update from the SGW to a packet data network gateway, i.e. PGW (108), receiving the update in the PGW, detecting the PS to CS handover indicator, and handling (307…
