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.

Abstract: In the GPRS when a MS moves from a former routing area to a new routing area, a method of supporting mobile Internet protocol characterized in that on receipt of a routing area update message from the MS, a mobile Internet protocol agent advertisement is sent only to that MS. The move may be inter-SGN or intra-SGN or may involve a change of RNC. The method allows efficient use of radio resources.
