Abstract
A method of controlling channel access for a mobile device in a wireless communication system includes receiving a dynamic persistence level from a base station, determining a persistence value according to the dynamic persistence level and at least a one persistence coefficient stored in the mobile device, comparing the persistence value with a random number of the mobile device, and determining whether access to a channel is permitted to be accessed for sending a message from the mobile device to the base station according to a comparison result of the persistence value and with the random number.
Claims28
A method of controlling channel access for a mobile device in a first wireless communication system, the method comprising:
- receiving a dynamic persistence level from a base station;
- determining a first persistence value according to the dynamic persistence level and at least one persistence coefficient stored in the mobile device;
- comparing the first persistence value with a first random number;
- and
- according to a first comparison result of the first persistence value with the first random number, determining whether a first channel is permitted to be accessed for sending a message from the mobile device to the base station.
A mobile device of a first wireless communication system for controlling channel access, the mobile device comprising:
- a storage unit for storing at least one persistence coefficient and program code corresponding to a process;
- and
- a processor coupled to the storage unit, for processing the program code to execute the process;
- wherein the process comprises:
- receiving a dynamic persistence level from a base station of the first wireless communication system;
- determining a first persistence value according to the dynamic persistence level and the at least one persistence coefficient;
- comparing the first persistence value with a first random number;
- and
- according to a first comparison result of the first persistence value with the first random number, determining whether a first channel is permitted to be accessed for sending a message from the mobile device to the base station.
A mobile device of a first wireless communication system for controlling channel access, the mobile device comprising:
- a wireless unit for receiving a dynamic persistence level from a base station of the first wireless communication system;
- a storage unit for storing at least one persistence coefficient;
- a first value determining unit for determining a first persistence value according to the dynamic persistence level and the at least one persistence coefficient;
- a comparing unit for comparing the first persistence value with a first random number;
- and
- an access determining unit for, according to a first comparison result of the first persistence value with the first random number, determining whether a first channel is permitted to be accessed for sending a message from the mobile device to the base station.
