POSITION REGISTRATION CANCELLING METHOD AND ITS DEVICE

摘要

PURPOSE: To relieve the installation load such as a storage capacity of a private communication system by deleting position information with respect to a mobile terminal PS 1 from the private communication system. CONSTITUTION: A channel number of a private communication system 3 and information of a PS 1 are transferred to a position information control section 10 via an exchange 4 by a position registration request sent by the PS 1 in an area of the private communication system 3. The position information control section 10 stores it on a position information table 12 that the position delete is required and stores a channel number being position cancellation to a position registration cancel request source table 14. When the PS 1 moves in an area of the radio base station 16 and makes a position registration request, the position information control section 10 confirms the necessity of position cancellation in the position information storage section 11 and obtains the channel number from a position registration cancellation request source storage section 13 and informs it to the private communication system 3 that the position information relating to the PS 1 is cancelled.
