Problems solved by technology

Currently, such systems create some inefficiencies in the use of the available radio frequency (RF) spectrum by generating unnecessary channel traffic
In addition, the way channel congestion is currently handled in such roaming systems further creates unnecessary channel traffic and delay times
Ultimately, the inability to provide roaming subscribers with one-way selective call receivers with an indication of registration status may defeat the purpose of messaging intended subscribers

Embodiment Construction

[0030] The present invention is directed to a selective call communication system capable of servicing or sending messages to receivers roaming between several coverage areas. An example of a selective call signaling system to which the present invention relates is disclosed in commonly assigned US Patent No. 5,128,665. The entire text and drawings of US Patent No. 5,128,665 are hereby incorporated by reference. However, the present invention is by no means limited to a particular type of signaling protocol, and has utility in many types of communication systems, paging or messaging systems being but one example.

[0031] Referring to Figures 1-3, there are shown a selective call communication system to which the present invention relates. The signaling system shown consists of 128 frames, each frame numbered 0-127. Frames are sent at 32 frames per minute, so that the total 128 frame period lasts 4 minutes. One hour is divided into 15 periods numbered 0-14. It is a synchro...

Abstract

The present invention relates to a congestion control method for a messaging system having a plurality of scanning selective call receivers with roaming capability comprises the steps of storing a priority value assigned to at least one of the identifiers for at least one of the plurality of scanning selective call receivers in a subscriber database at a home input terminal and matching the at least one identifier with at least one of the identifiers on the available communication resources found at the output controller terminal providing an identifier with a highest priority value. Then, the associated message is transmitted on the available communication resource having the identifier with the highest priority value if no congestion is detected on the communication resource and otherwise listing the communication resource on a communication resource congestion control list if the communication resource is deemed congested.

Description

technical field [0001] Field of the Invention This invention relates to messaging systems of all kinds, and more particularly to a messaging system that provides the ability for receivers to roam and efficiently receive messages across numerous coverage areas with numerous frequencies. Background technique [0002] In today's mobile society, no matter where a person goes, no matter near home, farther in the same country, or traveling around the world, people hope to be able to contact him, for example, through a selective calling receiver (pager) . Currently, such systems create certain inefficiencies in the utilization of the available radio frequency (RF) spectrum by generating unnecessary channel traffic. Additionally, the way channel congestion is currently handled in such roaming systems further creates unnecessary channel traffic and delay times. Ultimately, the inability to provide a roaming user with an indication of registration status to a one-way selective call ...
