The first message is usable to request to hand over a group of terminal devices under the first AND to the second AND. The group of terminal devices includes one or more terminal devices. In response to the first AND receiving a first response message from the second AND for the first message, the first AND sends a second message to the terminal devices. The first response message is usable to indicate that the terminal devices are allowed to be handed over to the second AND, and the second message is usable to indicate the terminal devices to be handed over to the second AND. After the terminal devices are handed over to the second AND, the first AND switches off one or more cells.

Abstract: A dynamic mobile network architecture is provided, with the objective of meeting greenhouse gas emission targets. The network adapts over time based on time varied traffic demand/load. This is achieved by providing two layers of base stations (BS). The top layer contains super BS that have larger coverage areas than the base stations of the second layer. Depending on traffic conditions, base stations of the second layer can be switched into a reduced power mode. Signalling procedures are provided for setting up connections between the BS of the second layer and the super BS, and for switching off and then activating previously switched off second layer BS. In some cases, the BS of the second layer has a lower power listening receiver to allow itself to be activated while the BS is otherwise powered off.
