Abstract

In the communications industry, more specitically the paging industry, messages are transmitted over the air via radio frequencies to a receiver or pager which is carried by a customer. The maximum distance between the transmitter and the receiver is determined by the amount of transmitter power and the number of trans- mitters. This distance is called the coverage area. A cus- tomer can remain completely mobile within the coverage area and still receive messages from the transmitter(s). However, there will be certain areas within the coverage area that radio frequencies can be blocked or altered (basements, tunnels, etc.) thus a message may not be received. These areas are generally well known by the service provider (Radio Common Carrier) and custom- ers are generally made aware that coverage in these areas is not guaranteed. A customer may also leave the speci- tied coverage area and will not receive any messages.

USER CONTROLLED RE-TRANSMIT OPTION

   In the communications industry, more specitically the paging industry, messages are transmitted over the air via radio frequencies to a receiver or pager which is carried by a customer. The maximum distance between the transmitter and the receiver is determined by the amount of transmitter power and the number of trans- mitters. This distance is called the coverage area. A cus- tomer can remain completely mobile within the coverage area and still receive messages from the transmitter(s). However, there will be certain areas within the coverage area that radio frequencies can be blocked or altered (basements, tunnels, etc.) thus a message may not be received. These areas are generally well known by the service provider (Radio Common Carrier) and custom- ers are generally made aware that coverage in these areas is not guaranteed. A customer may also leave the speci- tied coverage area and will not receive any messages.

  In order to overcome the possibility of a customer missing these messages, the paging terminal can be mod- ified to store all messages for a given customer within a selected prior period of time. The messages can then can be re-transmitted at a later time so that the cus- tomer may determine if any messages were missed. For example, if a customer realized that they had left the coverage area for 2 hours, they may, upon return to the coverage area, request a retransmission of all messages directed to them for the last 2 hours. When the terminal is conftgured to accept direct customer input, this request can be made by phone using a multiple digit code to identify the customer and selectthe prior period...
