Sleep-state for mobile terminal and service initiation for mobile terminals in sleep-state
First Claim
1. A method for initiating a service to a mobile terminal capable of communicating via at least a first and second access networks, wherein the first and second access networks use different access technologies and the mobile terminal is connected to the second access network and is in a deactivated state in the first access network, the method comprising:
- receiving at the mobile terminal a paging request directed to the mobile terminal through the first access network, the paging request being rerouted through the second access network, to which the mobile terminal is connected,starting initiation of the service by transmitting control signaling through the second access network,receiving at the mobile terminal via the second access network a command to activate the mobile terminal'"'"'s interface to the first access network, after system resources are reserved in the first access network, andactivating by the mobile terminal its interface to the first access network for continuing the initiation of the service or for receiving the service through 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.

8. A method for initiating a service for a mobile terminal through a first access network, wherein the mobile terminal is connected to a second access network via an Internet Protocol (IP) connection and is in a deactivated state in the first access network and the first and second access networks use different access technologies, the method comprising:
-
transmitting by a network entity in a core network to the mobile terminal a paging request directed to the mobile terminal through the first access network, the paging request being rerouted through the second access network IP connection, starting initiation of the service by control signaling with the mobile terminal through the second access network IP connection, configuring system resources for provision of the service in the first access network while initiation of the service is already started through the second access network IP connection, and transmitting from the network entity a command through the second access network IP connection to the mobile terminal to activate the interface of the mobile terminal to the first access network after the system resources are reserved in the first access network. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 23)

22. A mobile terminal capable of communicating via at least a first and second access networks, wherein the first and second access networks use different access technologies, the mobile terminal comprising:
-
a first network interface to communicate t access network; a second network interface to communicate with a second access network; and a controlling unit comprising one or more processors configured to; place the first network interface in a deactivated state; activate the second network interface to connect to the second access network; receive a paging request directed to the mobile terminal through the first access network for provision of a service, the paging request being rerouted through the second access network, to which the mobile terminal is connected via the second network interface; start initiation of the service based on control signaling through the second access network; receive an activation command via the second access network after system resource are reserved in the first access network, the activation command indicative of activation of the first network interface to connect to the first access network; and responsive to the receipt of the activation command, activate the first network interface to the first access network for continuing the initiation of the service or for receiving the service through the first access network.
