A METHOD AND A SYSTEM FOR ACTIVITY SUPERVISION IN A MOBILE TELEPHONE NETWORK

摘要

The invention relates to a method of determining in a mobile telephone network when a mobile can be considered to be switched-off, so as to obviate the need of paging the location of the mobile concerned upon the occurrence of a terminating call thereto. The time of making each radio contact with the mobile is recorded, and upon the occurrence of a terminating call, the difference between the time of this occurrence and the recorded time is calculated. The mobile is marked as being switched-off when this difference exceeds a given length of time.
