  • Method and apparatus for incorporating pager functionality into a land mobile radio system
    Patent number: 6912387
    Abstract: A land mobile radio system receives paging messages communicated via a paging service communication protocol, decodes the paging messages to identify respective target recipients of the paging messages and determines whether the target recipients are members of a user group. If a target recipient is a member of the user group, a communication unit (e.g., radio or console) of the target recipient is identified, the message is converted to an appropriate protocol (e.g., a wireless protocol) and sent to the communication unit.
