Problems solved by technology

[0004] Currently, a selective call transceiver in a messaging system with severe noise interference cannot receive messages unless the noise subsides, or the user of the selective call transceiver moves to another location where the interference is less severe
This situation can lead to message loss, which is not desired by the user

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.

Description

technical field [0001] The present invention relates generally to two-way messaging systems, and more particularly to two-way messaging systems employing frequency reuse. Background technique [0002] Current two-way messaging systems use frequency reuse to maximize the communication capacity of the system. Traditional frequency reuse schemes include a fixed number of communication cells. When the number of communication cells in the frequency reuse mode decreases, the system capacity increases, and besides, the noise interference of the communication system also increases. On the contrary, when the number of communication cells in the frequency reuse scheme increases, the system capacity decreases, and besides, the noise interference of the communication system also decreases. [0003] Noise interference includes co-channel interference and adjacent channel interference. Co-channel interference occurs between communication cells using the same communication frequency. A...
