SLEEP-STATE FOR MOBILE TERMINAL AND SERVICE INITIATION FOR MOBILE TERMINALS IN SLEEP-STATE
First Claim
1. A communication apparatus in a second access network capable of communicating with a mobile terminal capable of communicating with a core network via a first access network or the second access network, wherein radio access technology of the first access network is different from radio access technology of the second access network, the communication apparatus comprising:
- a transmitter, which, in operation, forwards a paging request to the mobile terminal, wherein the paging request addressed to the mobile terminal is 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; and
a receiver, which, in operation, receives a message from the mobile terminal 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 transmitter, in operation, transmits a handover command through the second access network to the mobile terminal, the handover command directing the mobile terminal to perform handover to the first access network and to connect to the first access network.

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 performed by a communication apparatus in a second access network capable of communicating with a mobile terminal capable of communicating with a core network via a first access network or the 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:
-
forwarding, by the communication apparatus, a paging request to the mobile terminal, wherein the paging request addressed to the mobile terminal is 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; receiving, by the communication apparatus, a message from the mobile terminal through the second access network in response to the paging request, the message requesting a service to be delivered through the first access network; and transmitting, by the communication apparatus, a handover command through the second access network to the mobile terminal, the handover command directing the mobile terminal to perform handover to the first access network and to connect to the first access network. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
