Registering a mobile terminal in an area of overlapping cell coverage by first and second networks
First Claim
1. A method of registering a mobile terminal in an area of overlapping cell coverage of first and second networks for wireless mobile telecommunications, the first and second networks being of different types and the first network comprising a controller, the method comprising registering the mobile terminal in respect of both networks by:
- storing in the controller an identifier of the mobile terminal;
storing in the controller a first record of in which routing/tracking area the mobile terminal is located in the first network and a second record of in which routing/tracking area the mobile terminal is located in the second network; and
the first network providing the mobile terminal with information of both records and said identifier.

Abstract
A method is provided of registering a mobile terminal in an area of overlapping cell coverage by first and second networks for wireless mobile telecommunications. The networks are of different types. The method comprises: storing an identifier of the mobile terminal; storing in a controller a first record of in which cell or group of cells the mobile terminal is located in the first network and a second record of in which cell or group of cells the mobile terminal is located in the second network; and providing the mobile terminal with information of both records and said identifier.

15. A method of a mobile terminal roaming in an area of overlapping cell coverage by first and second networks for wireless mobile telecommunications, the first and second networks being of different types and the first network comprising a controller, the method comprising registering the mobile terminal in respect of both networks by:
-
storing an identifier of the mobile terminal in the controller; storing in the controller a first record of in which routing/tracking area the mobile terminal is located in the first network and a second record of in which routing/tracking area the mobile terminal is located in the second network; the first network providing the mobile terminal with information of both records such that upon the mobile terminal roaming between the overlapping cells or groups of cells of the two networks, location update signalling to or from the mobile terminal does not occur.
