Sleep-state for mobile terminal and service initiation for mobile terminals in sleep-state
First Claim
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 a paging request, which is addressed to the mobile terminal to be routed through the first access network but is rerouted through the second access network when the mobile terminal is attached to the second access network;
a transmitter, which, in operation, transmits a message 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 through the second access network, the handover command directing handover to the first access network; and
control circuitry, which, in operation, connects to the first access network based on the handover command.

Abstract
The invention relates to the initiation of a service to a mobile terminal capable of communicating via at least a first and second access network. Further, the invention relates to a reduction of power consumption of mobile terminals supporting connectivity to at least two access networks. The invention also relates to mobile communication systems and in particular to mobile communications through heterogeneous access networks. In order to prove improved method for initiating services to mobile terminals and/or to reduce power consumption of mobile terminals, the invention introduces of a sleep state that can be entered by the terminal for an access system if same is not used. Upon requesting a service from/to the mobile terminal, the mobile terminal starts service initiation through a second access system and transits back to active state for the first access system for service provision.

10. A method for 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 method comprising the steps of:
-
receiving by the mobile terminal a paging request, which is addressed to the mobile terminal to be routed through the first access network but is rerouted through the second access network when the mobile terminal is attached to the second access network; transmitting, by the mobile terminal, a message through the second access network in response to the paging request, the message requesting a service to be delivered through the first access network; receiving, by the mobile terminal, a handover command through the second access network, the handover command directing handover to the first access network; and connecting by the mobile terminal to the first access network based on the handover command. - View Dependent Claims (11)
