Communication equipment, transcoder device and method for processing frames associated with a plurality of wireless protocols
View Patent ↗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., 105 ) of a transcoder ( 101 ) receives the dynamic transcoding attributes (e.g., 201–207 ) 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.
1. A method for a voice processing resource to process frames associated with a plurality of wireless protocols, the method comprising the steps of:
receiving, by the voice processing resource from a base site, a first frame associated with a first wireless protocol;
receiving, by the voice processing resource from a base site, a frame type of the first frame;
receiving, by the voice processing resource from a base site, delivery timing requirements of the first frame;
receiving, by the voice processing resource from a base site, a source type of the first frame; and
processing, by the voice processing resource, the first frame based on the first wireless protocol, the frame type, the delivery timing requirements, and the source type, wherein the first frame comprises a frame header and a frame payload, wherein the frame header of the first frame comprises a wireless protocol type of the first frame, the frame type of the first frame, the delivery timing requirements of the first frame, and the source type of the first frame.
2. The method of claim 1 further comprising the steps of:
receiving, by the voice processing resource from a base site, a second frame associated with a second wireless protocol, wherein the second wireless protocol is different than the first wireless protocol;
receiving, by the voice processing resource from a base site, a frame type of the second frame;
receiving, by the voice processing resource from a base site, delivery timing requirements of the second frame;
receiving, by the voice processing resource from a base site, a source type of the second frame; and

3. The method of claim 2 wherein the first frame comprises a frame header and a frame payload, wherein the frame header of the first frame comprises a wireless protocol type of the first frame, the frame type of the first frame, the delivery timing requirements of the first frame, and the source type of the first frame, wherein the second frame comprises a frame header and a frame payload, wherein the frame header of the second frame comprises a wireless protocol type of the second frame, the frame type of the second frame, the delivery timing requirements of the second frame, and the source type of the second frame.
4. The method of claim 1 further comprising the step of determining from the frame header of the first frame an indication of ordering for the first frame, wherein the step of processing the first frame comprises the step of processing the frame payload of the first frame based on the indication of ordering for the first frame.
5. The method of claim 4 wherein the indication of ordering for the first frame comprises a sequence number.
6. The method of claim 1 further comprising the step of determining from the frame header of the first frame a frame delivery mode for future frames, wherein the step of processing the first frame comprises the step of processing the frame payload of the first frame based on the frame delivery mode for future frames.
7. The method of claim 6 wherein the frame delivery mode for future frames comprises information selected from the group consisting of a frame delivery frequency, a frame delivery rate, an interval between frame deliveries, and a pattern of frame deliveries.
8. The method of claim 1 wherein the frame type comprises a number of packets in the payload of the first frame.
9. The method of claim 1 wherein the frame type comprises a type of each packet in the payload of the first frame.
10. The method of claim 9 wherein a type of a packet in the payload of the first frame comprises a type of a packet selected from the group consisting of audio, control, error correction, debug, diagnostic, TTY-Baudo, key size, key type, loading, timing, sequencing/ordering, and priority.
11. The method of claim 1 wherein the source type of the first frame comprises a source type selected from the group consisting of an asynchronous base site, a subscriber, an asynchronous transcoder, and a synchronous transcoder.
12. The method of claim 1 wherein the frame header of the first frame further comprises a system type and a call type from which a wireless protocol associated with the first frame is determined.
13. The method of claim 12 wherein the system type of the first frame comprises a system type selected from the group consisting of “iDEN”, TETRA, GSM, CDMA, “DIMETRA”, and “HARMONY”.
