Abstract

A communication terminal for receiving a communication service from a network that is configured to provide communication services to terminals via a plurality of communication devices, the terminal being configured to receive a communication service from a communication device, receive, from that communication device, a request that it handover from that communication service to another provided by the network and decide, responsive to that request, whether or not to handover from that communication service to another provided by the network.

Claims

1-23. -23. (canceled)

24. A communication terminal for receiving a communication service from a network that is configured to provide communication services to terminals via a plurality of communication devices, the terminal being configured to:

receive a communication service from a communication device;

receive, from that communication device, a request that it handover from that communication service to another provided by the network; and

decide, responsive to that request, whether or not to handover from that communication service to another provided by the network in dependence on how much data the communication terminal anticipates having to communicate in the future via the network.

25. A communication terminal as claimed in claim 24, configured to receive a request from the communication device that it handover to another communication device in the network, and to decide, responsive to that request, whether or not to handover from that communication device to another in the network.

26. A communication terminal as claimed in claim 25, configured to receive a request from the communication device that indicates an identity associated with one or more other communication devices in the network.

27. A communication terminal as claimed in claim 26, configured to decide whether or not to handover to another communication device in the network in dependence on those identities.

28. A communication terminal as claimed in claim 24, configured to receive a request from the communication device that it communicate via a different carrier frequency supported by the communication device and to decide, responsive to that request, whether or not to handover to that carrier frequency.

29. A communication terminal as claimed in claim 24, configured to decide whether or not to handover to another communication service in dependence on a signal quality associated with the other communication service.

30. A communication terminal as claimed in claim 24, configured to, if it determines that it will have relatively little data to communicate in the future, not handover to another communication service.

31. A communication terminal as claimed in claim 24, configured to, if it decides not to handover to another communication service, continue using the communication service.

32. A communication terminal as claimed in claim 24, configured to receive, as the request, an indication that the communication service is overloaded.

33. A communication terminal as claimed in claim 24, configured to decide independently of the communication device whether or not to handover from the communication service.

34. A communication device as claimed in claim 24, configured to decide whether or not to handover from the communication service using one or more algorithms adapted to optimise resource allocation across the network.

35. A communication network comprising a plurality of communication devices that are each configured to provide communication services to at least one communication terminal, the communication network being configured to:

determine that a communication service offered by one of the plurality of communication devices is overloaded and that a communication terminal receiving that communication service should handover from the overloaded communication service to another provided by the network; and

request the communication terminal to handover to another communication service;

the communication terminal being configured to decide, responsive to that request, whether or not to handover from that communication service to another in dependence on how much data the communication terminal anticipates having to communicate in the future via the network.

36. A communication network as claimed in claim 35, further comprising a communication terminal for receiving a communication service from a network that is configured to provide communication services to terminals via a plurality of communication devices, the terminal being configured to:

receive a communication service from a communication device;

receive, from that communication device, a request that it handover from that communication service to another provided by the network; and

decide, responsive to that request, whether or not to handover from that communication service to another provided by the network in dependence on how much data the communication terminal anticipates having to communicate in the future via the network.

37. A communication network as claimed in claim 35, configured to determine that a communication service offered by one of the plurality of communication devices is overloaded in dependence on a loading associated with others of the communication devices.

38. A communication network as claimed in claim 35, configured to determine that the communication terminal attached to the communication device should handover to another communication device.

39. A communication network as claimed in claim 35, configured to determine that the communication terminal attached to the communication device should handover to another carrier frequency supported by the communication device.

40. A communication network as claimed in claim 35, configured for machine-to-machine communication.

41. A communication network as claimed in claim 35, configured to operate in whitespace.

42. A method for providing communication services to a terminal via a communication network comprising a plurality of communication devices that are each configured to provide a communication service to at least one terminal, the method comprising:

determining that a communication service offered by one of the plurality of communication devices is overloaded and that a terminal receiving that communication service should handover from the overloaded communication service to another provided by the network;

requesting the communication terminal to handover to another communication service; and

deciding in the terminal, responsive to the request, whether or not to handover from that communication service to another in dependence on how much data the communication terminal anticipates having to communicate in the future via the network.

43. A communication network comprising a plurality of communication devices that are each configured to provide communication services to at least one communication terminal, the communication network being configured to:

determine that a communication service offered by one of the plurality of communication devices is overloaded and that a communication terminal receiving that communication service should handover from the overloaded communication service to another provided by the network; and

request the communication terminal to handover to another communication service;

the communication terminal being configured to decide, responsive to that request, whether or not to handover from that communication service to another in dependence on how much data the communication terminal anticipates having to communicate in the future via the network.

wherein the terminal is for receiving a communication service from a network that is configured to provide communication services to terminals via a plurality of communication devices, the terminal being configured to;

receive a communication service from a communication device;

receive, from that communication device, a request that it handover from that communication service to another provided by the network; and

decide, responsive to that request, whether or not to handover from that communication service to another provided by the network in dependence on how much data the communication terminal anticipates having to communicate in the future via the network.
