Abstract
A method and apparatus is used for transmitting an outbound message (408) in a two-way messaging system having a plurality of cells employing frequency reuse. The controller (112) of the two-way messaging system divides ones of the plurality of cells into a plurality of rings based on radio frequency propagation and interference environment. The controller (112) then sends to a portable selective call transceiver (122) a notification of the outbound message (408). In response, the controller (112) receives information sufficient to determine an identity of one of the plurality of rings in which the portable selective call transceiver (122) has determined itself to be located, and transmits the outbound message (408) to the portable selective call transceiver (122), utilizing a frequency reuse plan in accordance with the identity.
