Abstract:
A telecommunications system provides mobile communications to mobile user equipment and includes an internet protocol access network and a cellular mobile radio network. The mobile user equipment activates a connection on the cellular mobile radio network using the packet switched communications channel whilst receiving a communications service via the internet protocol access network. The mobile user equipment communicates via the connection on the packet-switched channel of the cellular mobile radio network in response to a handover event from the internet protocol access network to the cellular mobile radio network. The mobile user equipment also establishes a connection on the cellular mobile radio network using the circuit switched channel in response to the handover event, continues to communicate via the connection on the packet-switched channel while the connection on the circuit-switched channel has been established, and then communicates via the connection on the circuit-switched channel once it has been established.
