Abstract

A method includes determining if a user equipment is to be handed over to a target radio access node and if said user equipment suffers co-existence interference, and providing a message to be sent to said target radio access node, said message including interference information indicating that said user equipment suffers co-existence interference.

Claims

1-40. -40. (canceled)

41. A method comprising:

determining if a user equipment is to be handed over to a target radio access node and if said user equipment suffers co-existence interference; and

providing a message to be sent to said target radio access node, said message comprising interference information indicating that said user equipment suffers coexistence interference.

42. A method as claimed in claim 41, comprising transmitting said message to said target radio access node.

45. A method as claimed in claim 41, wherein said interference information comprises information indicating that co-existence interference is a reason for handover.

46. A method as claimed in claim 41, comprising providing frequency information about a frequency on which co-existence interference occurs.

47. A method as claimed in claim 41, comprising providing a message comprising additional information about one or more of:

problematic frequencies and interfering radio technologies.

57. A computer program comprising program code means adapted to perform the steps of any of claim 41 when the program is run on a data processing apparatus.

43. A method comprising:

obtaining from a message from a source radio access node, interference information indicating that a user equipment to be handed over has co-existence interference; and

controlling, in dependence on said interference information, a frequency of said user equipment when said user equipment has been handed over to avoid said co-existence interference

44. A method as claimed in claim 43, comprising receiving said message from said source radio access node.

48. An apparatus comprising at least one processor, and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to:

determine if a user equipment is to be handed over to a target radio access node and if said user equipment suffers co-existence interference; and

provide a message to be sent to said target radio access node, said message comprising interference information indicating that said user equipment suffers coexistence interference.

49. An apparatus as claimed in claim 48, comprising a transmitter configured to transmit said message to said target radio access node.

52. Apparatus as claimed in any of claim 48, wherein said interference information comprises information indicating that co-existence interference is a reason for handover.

53. Apparatus as claimed in any of claim 48, wherein the at least one memory and the computer program code are configured, with the at least one processor, to provide frequency information about a frequency on which co-existence interference occurs.

54. Apparatus as claimed in any of claim 48, wherein the at least one memory and the computer program code are configured, with the at least one processor, to provide a message comprising additional information about one or more of:

problematic frequencies and interfering radio technologies.

55. A source radio access node comprising the apparatus as claimed in claim 48.

50. An apparatus comprising at least one processor, and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to:

obtain from a message from a source radio access node, interference information indicating that a user equipment to be handed over has co-existence interference; and

control, in dependence on said interference information, a frequency of said user equipment when said user equipment has been handed over to avoid said co-existence interference

51. An apparatus as claimed in claim 50, comprising a receiver configured to receive said message from said source radio access node.

56. A target radio access node comprising the apparatus of claim 50.
