Abstract
A system for optimizing the operation of a plurality of radio modules incorporated within a wireless communication device (WCD) connected as a slave on a low-power wireless network, wherein a low-power device is acting as the master of the wireless network. The timing of communication between master and slave may be established by the master, and as a result, the WCD may utilize a control strategy to allow substantially concurrent active communication in one or more of the plurality of radio modules while still operating under the parameters set forth by the low-power master device.
Claims38
A method, comprising:
- participating in a wireless short-range communication network including at least one wireless communication device operating as a master;
- receiving information indicating a master device polling interval and a maximum period of time for response in order to maintain connectivity to the wireless short-range communication network;
- computing schedule information based on one or more of information received via the wireless short-range communication network or information available locally to a radio module, the schedule information indicating one or more time periods during which a the radio module communicating in the wireless short-range communication network is allowed to communicate;
- and
- determining a time to respond to a master device poll in order to maintain connectivity to the short-range communication network, wherein the time to respond is scheduled before the maximum period of time for response when a communication conflict involving the radio module is predicted to occur, based on the schedule information, at the maximum period of time for response.

A computer program product comprising computer executable program code recorded on a non-transitory computer readable storage medium, the computer program code comprising:
- code configured to cause an apparatus to participate in a wireless short-range communication network including at least one wireless communication device operating as a master;
- code configured to cause an apparatus to receive information indicating a master device polling interval and a maximum period of time for response in order to maintain connectivity to the wireless short-range communication network;
- code configured to cause an apparatus to compute schedule information based on one or more of information received via the wireless short-range communication network or information available locally to a radio module, the schedule information indicating one or more time periods during which the radio module communicating in the wireless short-range communication network is allowed to communicate;
- and
- code configured to cause an apparatus to determine a time to respond to a master device poll in order to maintain connectivity to the short-range communication network, wherein the time to respond is scheduled before the maximum period of time for response when a communication conflict involving the radio module is predicted to occur, based on the schedule information, at the maximum period of time for response.
