Abstract

Abstract When a mobile station (4) staying in a first paging zone (1) begins communication with a network through a base station by using a paging channel (P1) which is specific to the paging zone (1) and one of speech channels (S11-S20), and finishes the communication in a paging zone (2) after moving from the zone (1) to the zone (2), the paging channel in the waiting state after the speech in the zone (2) is not (P1), but (P2) which is specific to the zone (2). In order to assure that paging channel (P2), a base station in the zone (2) informs the mobile station (4) the paging channel (P2) which should be used in the waiting state in the disconnect signal. Thus, no switching of a paging channel in waiting state because of low receive level of the paging channel signal is necessary, and a quick service after previous speech is possible.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 141 words
A paging channel selection system in a mobile communication system, comprising: at least one base station means for forwarding a disconnect signal to a mobile station at the end of communication, said disconnect signal including a disconnect indication and a base station information including a paging channel number specific to said base station means; and at least one mobile station means for selecting paging channel in a waiting state according to said disconnect signal from the base station means, wherein said at least one mobile station means is coupled with a communication network through a respective base station means, and wherein said respective base station means forwards a highest receive level to a respective mobile station means as said respective mobile station means is coupled with said respective base station means due to a movement of said respective mobile station means.
Claim 2
Dependent Claim 141 words
A paging channel selection system in a mobile communication system, comprising: at least one base station means for forwarding a disconnect signal to a mobile station at the end of communication, said disconnect signal including a disconnect indication and a base station information including a paging channel number specific to said base station means; and at least one mobile station means for selecting paging channel in a waiting state according to said disconnect signal from the base station means, wherein said at least one mobile station means is coupled with a communication network through a respective base station means, and wherein said respective base station means forwards a highest receive level to a respective mobile station means as said respective mobile station means is coupled with said respective base station means due to a movement of said respective mobile station means.
Claim 3
Dependent Claim 88 words
A paging channel selection system according to claim 1, wherein said base station means has a switch for selectively connecting speech signal and a disconnect signal generator means operably coupled to a transceiver which is coupled with said respective mobile station means through an antenna, said disconnect signal generator means providing to said respective mobile station means a disconnect signal which has a synchronization bit, a disconnect indication, and a base station information including a paging channel which said respective mobile station means uses in said waiting state.
