Patent ID: 8111648

Claim:
A method of signaling protocol between transceivers that eliminates latency in sending voice packets over RF signals and greatly improves the voice quality of service using a medium access control protocol that combines contention-free and contention-based medium access control protocols into a heterogeneous medium access control protocol used for forwarding Internet Protocol packets containing voice traffic, signaling traffic, and application data traffic between a base station and mobile nodes in a voice over internet protocol system on a wireless network comprising: a base station in electrical communication with the Internet; one or more mobile nodes in wireless electrical communication with said base station; said base station and said one or more mobile nodes each having a medium access control protocol; said medium access control protocol having super-frames of equal intervals of time; each of said super-frames made up of an initial time for contention-free timeslot based access voice traffic and a remainder time for contention-based access signaling traffic and application data traffic; said base station dynamically determining a time duration of said super-frames and said initial time for contention-free timeslot based access based on a packetization interval determined by the duration of the voice traffic in said Internet Protocol packets for each of said super-frames such that each of said super-frames is long enough to transmit exactly one voice traffic packet and then said mobile node forwarding said voice traffic packet after each said voice traffic packet is generated; said initial time for contention-free timeslot based access then being divided into a control data timeslot, a downlink timeslot, and an uplink timeslot wherein the control data timeslot contains information regarding a current super-frame of said super-frames and said one or more mobile nodes are all capable of receiving said information during said control data timeslot in each of said super-frames; said contention-based access then containing control messages transmitted between said base station and said one or more mobile nodes when said one or more mobile nodes join or leave the wireless network or initiate a voice session; said one or more mobile nodes then using carrier sense multiple access with collision avoidance with binary exponential back off contention-based access; and, wherein said control messages are then assigned a highest priority, said signaling traffic are then assigned a lower priority, and said data application messages are then assigned a lowest priority.
