Method and apparatus for communicating push-to-talk state to a communication device
First Claim
1. A method for determining and setting a push-to-talk state in a communication device, the method comprising:
- at a communication device having a multilayer protocol stack for processing incoming messages;
receiving, from a peripheral that is wirelessly coupled to the communication device, a sequence of messages comprising a plurality of multi-byte data messages, wherein each of the multi-byte data messages provides a one-bit indication of a push-to-talk (PTT) state for the communication device, wherein the sequence of multi-byte data messages is received over a short range wireless data path for exchanging priority data that comprises a wireless serial communication channel and that is different from a short range wireless data path for exchanging non-priority data;
performing a pattern matching process, within the first two layers of the multilayer protocol stack, to determine the PTT state indicated by each of the multi-byte data messages;
setting the communication device to have the determined PTT states.

Abstract
Apparatus, which has a multilayer protocol stack for processing incoming messages, determines PTT state from messages received from a peripheral over a wireless serial communication channel. The apparatus: receives, from the peripheral, a sequence of messages comprising a plurality of data messages (e.g., RFCOMM messages), wherein each of the data messages provides an indication of a PTT state for the apparatus, and wherein the sequence of data messages is received over a short range wireless data path for exchanging priority data that comprises a wireless serial communication channel and that is different from a short range wireless data path for exchanging non-priority data. A pattern detector in the apparatus performs a pattern matching process, within the first two layers of the multilayer protocol stack, to determine the PTT state indicated by each of the data messages and sets the apparatus to have the determined PTT states.

13. Apparatus comprising:
-
a Bluetooth multilayer protocol stack for processing incoming messages; a Bluetooth radio that receives, from a peripheral that is wirelessly coupled to the apparatus, a sequence of messages comprising a plurality of multi-byte data messages, wherein each of the multi-byte data messages provides one-bit indication of a push-to-talk (PTT) state for the apparatus, wherein the sequence of multi-byte data messages is received over a short range wireless data path for exchanging priority data that comprises a wireless serial communication channel and that is different from a short range wireless data path for exchanging non-priority data; a pattern detector that; performs a pattern matching process, within the first two layers of the Bluetooth multilayer protocol stack, to determine the PTT state indicated by each of the multi-byte data messages; and sets the apparatus to have the determined PTT states. - View Dependent Claims (14)
