Title:
パケット・データ通信システムにおいて通信ユニットをページングするための方法および装置
Document Type and Number:
Japanese Patent JP4299933
Kind Code:
B2
Abstract:
A packet data communication system (100) that includes a plurality of communication units and a fixed infrastructure comprising a packet data routing system (101, 103) and a plurality of base sites (111-119), emloys a method and apparatus for paging a communication unit (110). The fixed infrastructure (101, 103, 111-119) transmits a paging message to a communication unit (110) of the plurality of communication units. In response to receiving the paging message, the communication unit (110) transmits an acknowledgment. If the fixed infrastructure (101, 103, 111-119) fails to receive the acknowledgment within a certain waiting period, the fixed infrastructure (101, 103, 111-119) waits at least until the expiration of a backoff period before again transmitting a paging message, wherein the length of time of the backoff period is based on a metric of known system behavioral patterns.
