Abstract

A mobile terminal for use in a communication system comprising a first, packet-based network and a plurality of wireless access networks providing access to the first network. The mobile terminal comprises: one or more transceivers for connecting to the wireless access networks; and processing apparatus coupled to the one or more transceivers, operable to communicate with the first network by forming connections with the access networks using the one or more transceivers. The processing apparatus is configured to access a database recording motion information relating to motion of connection points of the wireless access networks; and the processing apparatus is further configured to determine one of the wireless access networks for use in accessing the first network, in dependence on the motion information accessed from the database relating to one or more of the wireless access networks.

2. The mobile terminal of claim 1, wherein the processing apparatus is configured to automatically select which of a plurality of available ones of said wireless access networks to use to connect to the first network in dependence on the motion information accessed from said database relating to one or more of the wireless access networks.

3. The mobile terminal of claim 1, wherein the processing apparatus is configured to determine motion information relating to a connection point as experienced by the mobile terminal, and to thereby dynamically record the determined motion information in the database.

4. The mobile terminal of claim 1, wherein the database records the motion information for one or more of the access networks in association with times of day relevant to the availability of the respective access networks, and the processing apparatus of the mobile terminal is configured to determine one of the access networks for use in accessing the first network in dependence on the motion information and associated time of day.

5. The mobile terminal of claim 1, wherein the processing apparatus is configured such that said determination of one of the access networks comprises:

controlling activation of one or more of the transceivers to scan for availability of one or more of the access networks in dependence on the motion information accessed from said database relating to one or more of the wireless access networks.

6. The mobile terminal of claim 5, wherein the processing apparatus is configured to control activation of the local transceiver to perform the scan in further dependence on motion of the mobile terminal.

7. The mobile terminal of claim 5, wherein the processing apparatus is configured to suspend scanning if it is detected that the mobile terminal is moving.

8. The mobile terminal of claim 7 wherein the processing apparatus is configured to trigger scan if it is detected that the mobile terminal is no longer moving following said suspension of scanning.

9. The mobile terminal of claim 5, wherein the processing apparatus is configured to reduce a number of instances of the scan per unit time in dependence on whether the mobile terminal is moving or not.

10. The mobile terminal of claim 5, wherein the processing apparatus is configured to reduce a number of instances of the scan per unit time depending on a speed or velocity of the mobile terminal.

11. The mobile terminal of claim 1, wherein:
