Abstract

Appropriate system configuration allows for Fortunately, nearby zones can reuse the same sharing of inbound resources (channels and inbound channels and the same receivers, whi.le receivers) between nearby paging zones. data can be forwarded to the controllers of the different zones.

RECEIVER AND CHANNEL SHARING BETWEEN PAGING SYSTEMS

by Jheroen P. Dorenbosch and Kevin R. Wagner

  Appropriate system configuration allows for Fortunately, nearby zones can reuse the same sharing of inbound resources (channels and inbound channels and the same receivers, whi.le receivers) between nearby paging zones. data can be forwarded to the controllers of the different zones.

Inbound paging resources are very valuable.

  To do this in a straightforward way, one can configure shared receivers such that all received data are copied to all relevant controllers. The con- trollers are able to separate information that is des-

tined for its zone: scheduled inbound transmissions are only accepted if scheduled by the controller itself, while pager initiated (ALOHA) transmissions

are only accepted if the originating pager is regis- tered in the controller's zone. Registration Requests are handled specially. A drawback of this method is the network capacity used to send irrelevant infor- mation to the wrong zone, and the processing power needed at the controller to recognize irrelevant the information as such.

A better way to obtain reuse is to configure receivers such that data received during certain time

controller B

slots is sent to specific controllers. The system must be coordinated such that: each controller schedules inbound traffic only during the time slots allocat:ed for its use, each controller informs the pagers in its

zone which time slots are available for pager initiated transmissions, pagers only use these slots for ALOHA, and receivers send information received in a time slot only to the controller to which the time-slot is allocated....
