1. A mobile terminal capable of communicating with a core network via a first or second access network, wherein radio access technology of the first access network is different from radio access technology of the second access network, the mobile terminal comprising:

  • a receiver, which, in operation, receives from an entity in the core network a paging request, which is addressed using a first identifier to the mobile terminal to be routed through the first access network but is rerouted using a second identifier through the second access network when the mobile terminal is attached to the second access network;

    a transmitter, which, in operation, transmits a message to the entity through the second access network in response to the paging request, the message requesting a service to be delivered through the first access network;

    wherein the receiver, in operation, receives a handover command from the entity through the second access network, the handover command directing handover to the first access network; and

    control circuitry coupled to the receiver and the transmitter and, which, in operation, establishes a connection to the first access network based on the handover command.
