Managing incoming calls in connection-less areas

     One of the consequences of the major advances known in telecommunication networks over the past years is a growing need for users to be reachable in almost all situations. There are some cases, however, where this is not possible. For example in the underground or in any other place where there is no cell phone coverage or in a transport means where, for any reason, cellular phones must be switched off. In such situations indeed some problems may arise so that the user may not receive calls. This may cause particular concerns when a urgent communication must be delivered to this unreachable caller or when the caller needs to contact a person urgently because for example the called person has a meeting scheduled with the caller while the caller is late. A known approach to this problem is to record a message in an answering machine; however, this is quite time consuming and this does not prevent the caller from not being advised of delays, problems during his travel and of other dynamic information that needs to be transmitted to the user urgently.

     It is an object of the current article to propose a method and a system to address the above issues. This solution provides a user who is accessing a "no cellular phone coverage area" with a way to selectively allow an automatic answer to a predefined number of trusted people. A key aspect of this solution is that the answer is tailored to the single user and comprises detailed information about the current user area which is deprived of connection, the services condition, the user estimated position and the time at which the user is expected to exit from the current area. For example, considering a simplified scenario in which a user referred to as USER1 provided with a cellular phone device configures the automatic reply for a possible caller referred to as USER2. Assuming that when USER1 enters an area where he cannot be reached of the type underground station to take line A towards terminus Z, the cellular phone looses connectivity, and USER2 calls USER1 during this connectivity shortage period. In accordance with the proposed solution, the phone call will be deviated to a private underground cellular number and a previously recorded vocal message will start in which dynamically computed information will be added about the time USER1 has entered that specific underground station, the overall underground service functionality in the line USER1 is, USER1's direction and estimated exit time (when he goes out at terminus Z).

     The proposed solution is based on an additional plug-in that is installed on top of cellular phones and is responsible for handling the new service. A signal transmitter placed at the beginning and at the end of the area deprived of connection, and a signal receiver (RFID, IrDA, Bluetooth or other ) placed within the no connection area will be responsible for retrieving the direction of the user. The primary goal of t...
