Abstract
A messaging system capable of transmitting messages to receivers which roam between coverage areas. In one configuration, a coverage area (100) is divided into a plurality of zones (110). A single simulcast system identification (SSID) number is assigned which consists of a local identification number which identifies the coverage area (100), a zone identifier which identifies a zone (110) within the coverage area, traffic splitting flags and a frequency. For larger roaming areas, a network (200) is defined as consisting of a plurality of service areas (210) and is identified by network roaming identification information (NRI). NRI information and/or SSID information is stored in a receiver according to desired coverage and like information is transmitted in the corresponding zone or service area.
