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 connecting user equipment, i.e. UE, communicating wirelessly with the network. The method comprising steps of detecting that handover is required from a packet switched, i.e. PS, based network to a circuit switched, i.e. CS, based network, initiating in a source mobility management node a single radio voice call continuity, i.e. SVRCC, initiating a PC to CS handover for non-voice components with information about voice related parameters and a PS to CS handover indicator, executing hand over, sending an update request to a serving gateway, i.e. SGW, from a target mobility management node with non-voice related parameters and the PS to CS handover indicator, forwarding the update request from the SGW to a packet data network gateway, i.e. PGW, receiving the update request in the PGW, detecting the PS to CS handover indicator, and handling in the PGW the PS to CS handover indicator.
