Abstract: A wireless telephone system provides telecommunications services for personal wireless telephone sets over an area which is divided into service cells. Each of the cells is defined by reception characteristics of a plurality of radio base stations within the cell. The telephone system includes a service controller and a port being wireline connected between each radio base station and the service controller. The service controller selects radio base stations for setting up radio links with wireless sets of calling or called persons. A base station which serves a wireless set and surrounding idle base stations monitor strengths of radio signals received from the wireless set and report running averages of the monitored signal strengths to the service controller. Movement of the wireless set from one cell to another cell during a call is detected as a drop in the running average reported by the serving base station.

Abstract: A wireless telephone system is adapted for serving portable telephone sets of itinerant users. The wireless telephone system is provided with a plurality of radio base stations being organized in at least two groups or paging areas. Each group has a boundary, a portion of each boundary being overlapped by at least one other boundary, and at least two of the at least two groups having at least two radio base stations, one of which is in common with the other group. From time to time in relation to each group, a beacon signal is radio transmitted from a radio base station exclusive to the group for soliciting a recordation response from a portable telephone set of an itinerant user within a beacon zone. When the presence of a respondent portable set is recorded as being within a service area of one of the groups, the portable set is instructed not to respond to subsequent occurrences of the same beacon signal for some hours to avoid cluttering the wireless spectrum with undue supervisory signalling.
