Abstract: A method and apparatus for preventing the fraudulent access of a mobile terminal is disclosed. The mobile terminal includes a user profile defining particular behaviors which are allowed by the mobile station in response to the initiation of certain types of calls. Control logic associated with the user profile determines, in response to the initiation of a telephone call, if the behavior required by the requested telephone call would comprise an allowed behavior as defined by the user profile. The control logic then grants or denies continuation of the call based upon this comparison.

Abstract: A person paging method in which a first user (A) wishes to page and transmit a message to a second user (B) with the aid of a paging service. The first user (A) requests paging of the second user (B) at a paging central (1) which offers an alerting service and a message service which supplements the alert with the message. The paging central (1) alerts the second user (B) by means of the alerting service. The invention is characterized in that the paging service is not associated with any particular telecommunication network, but can be performed in at least one telecommunication network (e.g. in N1 and N5) chosen from among at least two possible telecommunication networks (N1-N5). The message service is also made independent of the alerting service, in that the message service is not activated until a request to do so is received from the second user.

Abstract: A system and method are disclosed in which a service provider in a first environment of a first plurality of competing, overlapping mobile networks has at least one service node. The service provider offers subscriptions based on SIM modules from at least one of a second plurality of mobile telephone operators in a second environment. The first plurality of operators has agreements for interconnect traffic with the second plurality of operators. Mobile users that are visitors in the first environment can communicate, through any appropriate network selected from the first plurality of mobile networks, which avoids the detouring of incoming calls to the visiting mobile users.
