  • the present invention relates to a system for remotely operating a mobile telecommunication device so as to select a set of control frequencies associated to a predetermined telecommunication service provider, the selection being performed upon short-range, point-to- point interaction between network selection devices arranged at key locations within the coverage area of the service provider, and mobile telecommunication devices equipped with short-range interaction units.

  • a user Whilst committed to the chosen home network operator by the subscription agreement, a user is not allowed, in general, to utilize any other services than those provided by that operator, at least as long as the user is located within the radio coverage area of his home network operator, in most cases within his own country of residence. Outside that geographical extent, for example as the user is visiting a foreign country where his home network is not longer available, the user is generally able to operate his mobile device on a cellular system other than the home network, provided that the foreign system company and the home network operator cooperate with one another in a manner that permits roaming services, for example when both companies have some kind of reciprocal billing arrangement.
  • conventional mobile devices are configured so that it automatically selects a foreign service operator as soon as the home network is not longer available. Such a selection of a foreign network is performed in accordance with a predetermined default selection process which is consistent with the home system. Using such a default selection process, the mobile device initiates a search for a connection with a foreign network comprised in a priority list which is pre-established by the home network operator. In the absence of specific contractual considerations between the home network operator and a preferred operator locally registered within the new coverage area, the mobile device attempts to establish a connection with the latest utilized network, or, more currently, the network offering the highest Received Signal Strength Indication (RSSI) at the actual location.
  • RSSI Received Signal Strength Indication
  • the default selection process provides efficient network selection without the need for a user to actively take part of the process by manually selecting a foreign network. While default selection processes spare a user the troublesome task of choosing a particular operator among those available, it also tends to limit the benefits that competition between different operators may provide. In fact, even assuming that a user knows exactly which foreign network he wants to utilize, the task of selecting it is perhaps hard enough to discourage him.
  • Conventional mobile telecommunication devices are usually equipped with setting selection units that permit alteration of the default selection process. However, those features are not often utilized because an intelligent nondefault setting selection requires not only an understanding of cellular radiotelephony, but also a comparative information about different services provided, or about different rates charged by every selectable operator.
