Method and system for providing access to a channel for voice transmissions |
摘要 |
In a TDMA system whereby the TDMA system comprises a plurality of subscriber units and a plurality of base radios, a method and system for providing access to a channel for voice transmissions where the first subscriber unit determines whether it is provisioned for polite access to the channel. In addition, the first subscriber unit is characterized by a first color code and a first talkgroup ID. The first subscriber unit also examines the voice transmissions on the channel for voice transmissions that are from a second subscriber unit with a second color code and a second talkgroup ID. If the first color code and the second color code match and if the first talkgroup ID and the second talkgroup match, then the first subscriber unit is allowed access to the channel for voice transmissions even though the channel is being used for voice transmissions by the second subscriber unit. |
