DEVICE AND METHOD FOR GENERAL CALLING FOR MOBILE DATA COMMUNICATION SYSTEM

摘要

The present invention aims at reducing invalid traffics when a paging is to be performed in a mobile data communication system including a communication terminal connected with data terminals. To achieve this object, the communication terminal (102) is provided with a notice means (204) for recognizing a state of use of itself and states of use of the data terminals (1031) through (103n) and notifying a result of the recognition to the network side, whereas the network system (101) is provided with a storage means (303) for registering a communication terminal in which the communication terminal (102) and at least one of the data terminal (1031) through (103n) became usable and deleting the registration of the communication terminal (102) or a communication terminal in which the data terminals (1031) through (103n) became unusable, in accordance with a result of the notice made by the notice means (204), so that a receiving possible state of the communication terminal (102) is preliminarily registered on the side of the network system (101). Moreover, the receiving standby state is discriminated between a voice- only standby state and a voice and packet simultaneous standby state. When the standby state appears to be the former, a voice paging is made and when the latter, a packet paging is made, both by the communication means (301). <IMAGE> <IMAGE>
