Abstract
A delegate-based group channel access method is disclosed for machine-to-machine (M2M) communication. The delegate-based group channel access method groups M2M devices having common characteristics together, assigns a single delegate or multiple delegates from the group according to some criteria, and uses the assigned delegate to perform channel access. This method avoids unnecessary peer-to-peer communication between M2M devices reduces the probability of collision on the channel during initial channel access, and reduces the control signaling overhead. The, delegate-based group channel access method also coordinates the number of slots to backoff so that all M2M devices in the group keep pace with the delegate.
Claims23
A method to perform machine-to-machine (M2M) communication in a wireless network, the method comprising:
- collecting, by a base station in the wireless network, a plurality of M2M mobile stations in the wireless network into a group based on a common characteristic of the plurality of M2M mobile stations;
- selecting, by the base station, a delegate M2M mobile station from the collected group;
- and
- receiving, by the base station, a ranging code from the delegate M2M mobile station on behalf of the group, wherein the group is trying to access a wireless channel.
The method of claim , selecting, by the base station, a delegate M2M mobile station from the collected group further comprising:
- for each of the plurality of M2M mobile stations in the group, determining, by the base station, a channel quality, wherein one of the plurality of M2M mobile stations has a higher channel quality than that of the remaining M2M mobile stations;
- and
- selecting the delegate M2M mobile station having the higher channel quality.
A method to perform machine-to-machine (M2M) communication in a wireless network, the method comprising:
- transmitting, by a delegate M2M mobile station in the wireless network, a ranging code to a base station in the wireless network, wherein the delegate M2M mobile station transmits on behalf of a group of one or more M2M mobile stations, wherein the one or more M2M mobile stations in the group share a common characteristic;
- wherein the delegate M2M mobile station is attempting to access a wireless channel on behalf of the group.
A method to perform machine-to-machine M2M communication in a wireless network, the method comprising:
- receiving, by a base station in the wireless network, a ranging code from a delegate M2M mobile station on behalf of a group, the group comprising a plurality of M2M mobile stations, the group being identified to the base station by a M2M group identifier (MGID);
- wherein the plurality of M2M mobile stations are part of the group based on a common characteristic;
