Each mobile unit (108,110) in a cellular communications system (100) accumulates at least one mobility or communications traffic (teletraffic) statistic representative of "typical" operation of the mobile unit within the cellular communications system. The mobile units process or collect the statistics and then transmit the aggregate statistics to a microcell (102) or macrocell (104) base station (106 or 112) at time of origination of a call to or from the mobile, request for a handoff of a call by the mobile unit or the registration process. Included within the characteristics which can be monitored in accordance with the present invention are the following: cell sojourn time; area sojourn time; call holding times; call throughput; number of previous handoffs in an ongoing call; time periods between two consecutive failed handoffs for the mobile unit; and, the ratio of calls originating from a mobile unit to the number of calls terminating to a mobile unit. The accumulated data representative of these characteristics are utilized by the receiving base station (106 or 112) to assign new and handoff calls to a microcell (102) or a macrocell (104), to prioritize call handling within the cellular communications system and to assign customzied customer service areas. <MATH> |
