Abstract: A communications system in which information is transmitted in a plurality of time slots grouped into a plurality of superframes which are, in turn, grouped into a plurality of paging frames. A remote station receives paging messages once in each paging frame.

Abstract: In a mobile radiotelephone system, a base station, upon receiving a service request from a mobile station, ascertains whether the service request can be accepted according to the availability of voice channels in the base station, and, if the service request cannot be accepted, compares a measured signal strength of the service request with at least one threshold value. If the signal strength exceeds the threshold, the mobile station is directed to retry the service request on one or more of a first set of channels assigned to neighboring base stations. Otherwise, the mobile station is directed to retry the service request on one or more of at least a second set of channels assigned to neighboring base stations. Accordingly, directed retries nearer the interior of a cell may be restricted or eliminated, whereas directed retries toward the periphery of the cell may be freely allowed or less severely restricted.

Abstract: A method for use in a cellular radio telephone system for controlling, in at least one mobile station, rescanning operations of paging channels in the system, wherein the mobile station is operationally connected to at least one base station. The method involves broadcasting a rescan message from the base station to the mobile station at predetermined intervals during operation of the base station. Pages to be sent to the mobile stations are stored immediately following broadcast of the rescan message until such time as all mobile stations have had an adequate opportunity to carry out the rescanning operation.
