Abstract: A cellular radio communications system comprises: at least one base station for broadcasting radio signals to mobile stations within a cell; a mobile station addressable using IP addresses; and a first controller in the cell of the cellular radio communications system, the first controller being adapted: (i) to receive a request from the mobile station that the cellular radio communication system assign to the mobile station the static IP address previously assigned to the mobile station outside of the cell; (ii) in response to the request from the mobile station, to check with a second controller associated with the location where the mobile station was previously registered that the static IP address has not been assigned to another mobile station; and (iii) to assign the static IP address previously assigned to the mobile station, outside of the cell, to the mobile station for use in the cell, if the static IP address has not been assigned to another mobile station. Alternatively, the first controller may perform the check for availability of the static IP address with a controller associated with the location where the static IP address is registered. The invention also comprises methods of mobile station registration in cellular radio communication systems. The invention enables roaming by a mobile station between cellular systems which are under the control of different Software and Measurement Infrastructures. Mobile stations may be adapted to check one or more timers prior to making the static IP address request.

Abstract: Un sistema de comunicaciones por radio celular que tiene al menos una primera y una segunda red de radio que tienen diferentes zonas de cobertura geométrica, incluyendo el sistema de comunicaciones radio celular: una estación móvil (374) direccionable usando direcciones IP de Protocolo de Internet, estando adaptada la estación móvil para itinerar entre la primera y segunda red de radio, incluyendo la primera red una red doméstica de la estación móvil y la segunda red incluyendo una red extranjera de la estación móvil; un primer controlador (200) asociado con la primera red; y caracterizado el sistema por un segundo controlador (300) asociado con la segunda red, estando adaptado el segundo controlador (300) cuando la estación móvil (374) está en itinerancia de la primera red a la segunda red: (i) para recibir una petición de activación de contexto de la estación móvil (374) para que el sistema de comunicaciones radio celular asigne a la estación móvil (374) una dirección IP estática previamente asignada a la estación móvil (374) por el primer controlador (200); (ii) en respuesta a la petición de la estación móvil (374), comprobar con el primer controlador (200) que la dirección IP estática no ha sido asignada a otra estación móvil; y (iii) para asignar la dirección IP estática previamente asignada a la estación móvil (374) por el primer controlador (200) a la estación móvil (374) para uso en la segunda red, si la dirección IP estática no ha sido asignada a otra estación móvil.

Abstract: A cellular communications system including at least one base station (358), mobile stations (372, 374) addressable using IP addresses within a cell (350), and a controller (300) adapted to receive a context activation request from the mobile (374) to assign a static IP address previously assigned to the mobile when it was outside of the cell (350) and to assign the static IP address if the second controller (200) associated with the location where the mobile was previously registered with the static IP address has not already reassigned it, thus enabling roaming of the mobile between cellular systems under control of different Software and Measurement Infrastructures.
