Abstract

The present invention relates to a method for controlling sleep mode in a terminal comprising at least two network interfaces. According to the present invention, the method comprises the steps of: Switching off one of the two interfaces; Activating the switched off interface for a predefined time window upon reception of a predefined signaling message on the other interface.

Claims

1. Method for controlling sleep mode in a terminal comprising at least two interfaces to different networks, said method comprising the steps of:

Switching off one of the two interfaces;

Activating said switched off interface for a predefined time window upon reception of a predefined signaling message on said other interface.

2. Method according to claim 1, wherein said terminal is a dual mode terminal comprising an ad-hoc interface and a cellular network interface.

3. Method according to claim 1, wherein said terminal is a multimode terminal having two ad-hoc interfaces of different type.

4. Method according to claim 2, wherein said ad-hoc interface is switched off and activated upon reception of a signaling message over said cellular interface.

5. Method according to claim 2, wherein said cellular interface is switched off and activated upon reception of a signaling message over said ad-hoc interface.

6. Method according to claim 2, wherein said ad-hoc interface belong to the group of Bluetooth interface, WLAN interface.

7. Method according to claim 2, wherein said predefined signaling message is part of the cellular network radio resource control protocol sent on cellular signaling channels channel.

8. Access network node of a cellular communication network comprising means for sending a predefined signaling message to a dual mode terminal comprising a cellular network interface and an ad-hoc interface, said message comprising an indication to activate said ad-hoc air interface if said ad-hoc interface is currently switched off.

9. Dual mode terminal comprising at least two interfaces to different networks, said terminal comprising means for controlling sleep mode on at least one of said two interfaces, said dual mode terminal being wherein further comprises

Means for switching off one of the two interfaces;

Means for activating said switched off interface for a predefined time window upon reception of a predefined signaling message on the other interface.
