Abstract

Each trunking system control channel message is a fixed size and can contain a fixed amount of information, When the size of the data required to be sent exceeds the capacity of a control channel message, multiple messages must be used to pro- vide the data. Using multiple messages increases con- trol channel loading and lowers system efficiency.

required. The new method must still provide a means of identifying the source ofthe data.

BACKGROUND

  Each trunking system control channel message is a fixed size and can contain a fixed amount of information, When the size of the data required to be sent exceeds the capacity of a control channel message, multiple messages must be used to pro- vide the data. Using multiple messages increases con- trol channel loading and lowers system efficiency.

  Currently, control channel messages originating from a radio, contain data as well as the radio's ID. The ID is used by other system components to iden- tify the source of the data. What is needed is a means to increase the data capacity of a control channel message so that a single message can be used in situations where multiple messages were previously

SOLUTION

  The idea presented in this disclosure is used when individually polling a group of radios. In response messages from a radio, some of the message space which is normally used for the radio ID is used to contain additional data. The complete radio ID is no longer included in the message but is replaced by a smaller sized many-to-one identifier. Exact iden- tification of the source of the message is maintained by controlling so that only one radio with a particu- lar identifier can be pending to send a message at any instant.
