Abstract: 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.

Abstract: A wireless communication system employs a method and apparatus for providing voice recognition service to a wireless communication device. Voice recognition information (e.g., a context model and voice training parameters) is generated by a wireless device user and stored in a memory (e.g., a SIM card) of the wireless device to form one portion of a voice recognition processing engine. Another portion of the voice recognition processing engine (e.g., a voice recognition processor and operating software therefor) is implemented in a wireless system infrastructure of the wireless communication system. The wireless device transmits the voice recognition information to the system infrastructure preferably upon request for such information by the system infrastructure. The system infrastructure then uses both portions of the voice recognition processing engine to provide voice recognition service to the wireless device and its user during operation of the wireless device.
