Abstract
There is provided a method of operating a network node in a first network that is operating according to a first radio access technology, RAT, the network node controlling a first cell in the first network, the method comprising receiving information for a terminal device served by the first cell (913; 1113), the received information corresponding to information for the terminal device that was provided to the terminal device from another cell of the first network, the information being for use in a network interworking feature that enables and controls interworking between the first network and a network operating according to a second RAT.
Claims33
A method of operating a network node in a first network that is operating according to a first radio access technology, RAT, the network node controlling a first cell in the first network, the method comprising:
- receiving information for a terminal device served by the first cell, the received information corresponding to information for the terminal device that was provided to the terminal device from another cell of the first network, the information being for use in a network interworking feature that enables and controls interworking between the first network and a network operating according to a second RAT.
-22. (canceled)
A network node for use in a first network that is operating according to a first radio access technology, RAT, the network node supporting a network interworking feature that enables and controls interworking between the first network and a network operating according to a second RAT, the network node controlling a first cell in the first network, the network node comprising:
- a processing circuit and interface circuitry that are configured to:
- receive information for a terminal device served by the first cell, the received information corresponding to information for the terminal device that was provided to the terminal device from another cell of the first network, the information being for use in the network interworking feature.
-44. (canceled)
A method of operating a network node in a first network that is operating according to a first radio access technology, RAT, the network node controlling a second cell in the first network, the method comprising:
- sending information for a terminal device that was used in the second cell to a network node controlling a first cell the information being for use in a network interworking feature that enables and controls interworking between the first network and a network operating according to a second RAT.
-52. (canceled)
A network node for use in a first network that is operating according to a first radio access technology, RAT, the network node supporting a network interworking feature that enables and controls interworking between the first network and a network operating according to a second RAT, the network node controlling a second cell in the first network, the network node comprising:
- a processing circuit and interface circuitry that are configured to:
- send information for a terminal device that was used in the second cell to a network node controlling a first cell, the information being for use in the network interworking feature.
-60. (canceled)
A method of operating a terminal device in a first network that is operating according to a first radio access technology, RAT, the terminal device supporting and operating according to a network interworking feature that enables and controls interworking between the first network and a network operating according to a second RAT, the method comprising:
- sending information for the terminal device to a network node controlling a first cell in the first network, the information having been previously used by the terminal device in another cell in the first network, the information being for use in the network interworking feature.
-73. (canceled)
A terminal device for use in a first network that is operating according to a first radio access technology, RAT, the terminal device supporting and operating according to a network interworking feature that enables and controls interworking between the first network and a network operating according to a second RAT, the terminal device comprising:
- a processing circuit and transceiver circuitry that are configured to:
- send information for the terminal device to a network node controlling a first cell in the first network, the information having been previously used by the terminal device in another cell in the first network, the information being for use in the network interworking feature.
