Method and apparatus for dynamically changing a maximum access channel rate
View Patent ↗A method, device and computer-readable storage element for dynamically changing a maximum access channel rate at a site in a communication system. The method includes setting a maximum access channel rate for an access channel at a site, which comprises a coverage area for a base station. The method further includes determining a first access probe success rate that measures a rate at which first attempt access probes sent from the terminals on the access channel are received, and changing the maximum access channel rate based on the first access probe success rate.
1. A method for dynamically changing a maximum access channel rate at a site in a communication system, the method comprising:
setting a maximum access channel rate for an access channel at a site which comprises a coverage area for a base station;
determining a first access probe success rate that measures a rate at which first attempt access probes sent from the terminals on the access channel are received;
changing the maximum access channel rate based on the first access probe success rate;
determining a load level for the access channel; and
changing the maximum access channel rate based on at least one of the first access probe success rate and the load level;
wherein if there is a conflict between changing the maximum access channel rate based on the first access probe success rate and changing the maximum access channel rate based on the load level, then changing the maximum access channel rate based on the load level.
2. The method of claim 1 wherein changing the maximum access channel rate comprises:
comparing the first access probe success rate to at least one threshold; and
changing the maximum access channel rate based on results of the comparison.
3. The method of claim 2 wherein the at least one threshold comprises an upper and a lower threshold.
4. The method of claim 1 wherein the maximum access channel rate is selected from one of 9.6 kilobits per second (kbps), 19.2 kbps, or 38.4 kbps.
5. A device operable to dynamically change a maximum access channel rate at a site in a communication system, the device comprising:
a transceiver; and
a processing device coupled to the transceiver and programmed to perform a method comprising:
setting a maximum access channel rate for an access channel at a site which comprises a coverage area for a base station;
determining a first access probe success rate that measures a rate at which first attempt access probes sent from the terminals on the access channel are received;
changing the maximum access channel rate based on the first access probe success rate;
determining a load level for the access channel; and
changing the maximum access channel rate based on at least one of the first access probe success rate and the load level;
wherein if there is a conflict between changing the maximum access channel rate based on the first access probe success rate and changing the maximum access channel rate based on the load level, then changing the maximum access channel rate based on the load level.
6. The device of claim 5 wherein the processing device is further programmed to perform:
comparing the first access probe success rate to at least one threshold; and
changing the maximum access channel rate based on results of the comparison.
