摘要

1. A method of registering a mobile terminal in a service overlap area of cells of the first and second wireless mobile telephone networks, which are networks of various types and comprising a controller, the mobile terminal being registered with respect to both networks and wherein:! save the identifier of the mobile terminal in the controller,! store in the controller the first information about in which tracking / routing zone of the first network the mobile terminal is located, and the second information about in which tracking / routing zone of the second network the mobile terminal is located, and! provide both these information and the identifier mentioned to the mobile terminal. ! 2. The method according to claim 1, in which both the information is provided to the mobile terminal so that when roaming the mobile terminal between overlapping cells or groups of cells of both networks, there is no exchange of positioning signals with the mobile terminal. ! 3. The method according to claim 1, wherein said controller is located in the first network and mediates the registration of the mobile terminal in the controller of the second network. ! 4. The method according to claim 1, in which the controller or each controller is a corresponding node in the core network. ! 5. The method according to claim 1, in which the mobile terminal leaves the service area of at least one of two overlapping cells, and said controller provides the second controller with additional information about which new cells or groups of cells of each network have moved to the service area mobile terminal. ! 6. The method according to claim 5, in which one of the additional information mentioned is
