[0003]

By the way, in the above-mentioned conventional mobile terminal paging method, in the former all-cell page method, a paging (page) signal is generated for all incoming calls of all mobile terminals. Since the transmission is performed, there is a problem that as the mobile terminal and the traffic increase, the channel usage rate in the downlink direction (direction from the radio base station to the mobile terminal) of the radio control channel is suppressed.

[0004] On the other hand, in the latter partial page method, the location registration signal is periodically transmitted from all mobile terminals in the uplink direction of the radio control channel (direction from the mobile terminal to the radio base station). There was a problem that pressed down the usage rate.

[0005] Further, both of these systems generate a large amount of radio control channel signals, so that the load on the processing unit of the mobile communication control unit is increased, and a large-capacity processing unit is required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a paging method for a mobile terminal that reduces the usage rate of a radio control channel and reduces the load on a control device. .

[0007]

In order to achieve the above object, a mobile terminal calling system according to the present invention provides a plurality of mobile radio terminals accommodated in a mobile communication system utilizing a plurality of radio services. Transmission means for transmitting a service area division and a use time zone to be used in advance to the mobile communication control device via a radio control channel, wherein the mobile communication control apparatus includes the transmitted service area division and use time. Registration means for registering a band, confirmation means for confirming whether a current time is the pre-registered time band when an incoming call to the wireless terminal is generated in the mobile communication control device, and Paging for transmitting a paging signal of the wireless terminal to a radio control channel only for a service area division registered in advance. A configuration equipped with means.

[0008]

According to the mobile terminal paging method having the above-mentioned structure, the mobile terminal previously uses the uplink of the radio control channel to transmit the service area division information and the use time zone information used by the subscriber in communication. When the mobile communication control device sends an incoming call to the wireless terminal, the mobile communication control device checks whether the time period is registered in advance and registers the information in advance. The wireless terminal transmits a paging signal of the wireless terminal to the wireless control channel only to the service area in which the wireless terminal is set.
