To address the need for an apparatus and method for transcoding among multiple wireless protocols, the present invention provides a framework for more generalized transcoding. A voice processing resource (e.g.,) of a transcoder () receives the dynamic transcoding attributes (e.g.,) for a frame and then transcodes that frame according to the requirements of the transcoding attributes. These dynamic attributes may contain information such as the wireless protocol involved, the frame type, the source type, the sequence number, the delivery timing requirements, and the delivery mode of subsequent frames.

A vehicular adapter system is described having wireless local area network (WLAN) capabilities. The adapter system includes an adapter configured to plug into a cigarette lighter socket of a vehicle. The adapter has a WLAN module contained therein, and is configured to electrically couple the WLAN module to a wireless communication device. The WLAN module is operable to communicate with other WLAN-enabled devices in the vehicle, such as a head unit with another embedded WLAN module. The interoperability of the WLAN modules provide hands-free audio operation of a radiotelephone that is not WLAN-enabled using existing vehicular audio transducers.

A full duplex wireless communication system () one or more wireless communication devices () and fixed infrastructure equipment that includes at least a transcoder (), a router () and a base transceiver site (BTS,). To reduce delays of information packets communicated between the transcoder and the BTS, the transcoder, router and BTS employ a unique synchronization-based priority scheme. In accordance with the priority scheme, an indication of the status of synchronization between the transcoder and the BTS is included in an information pace to guide the router's processing of the packet. In the event that the router stores the packet the router preferably inserts a time-delay indication into a portion of the packet. The BTS uses the time-delay indication to determine a desired transcoder transmission time, and communicates an indication of the desired transcoder transmission time to the transcoder.

A packet prioritization and transmission algorithm for on demand transportation of data packets having different priorities through a shared packet pipe. The algorithm comprises prematurely ending the transmission of a packet having a low priority; placing the remainder of the packet having the low priority in a storage means, holding data of the packet having the low priority in the storage means, transmitting a packet having a high priority, transmitting the remainder of the packet having the low priority once the packet having the high priority is finished transmitting, flagging a packet header of a packet having the low priority to identify pending packets to allow for transmission of packets having the high priority; and determining a priority of an incoming packet.
