Method for assigning of channel capacity to communication links
View Patent ↗A method for assigning of channel capacity to communication links in a cellular communication system and to an access controller for controlling the access of contending terminals to channel capacity of a cellular communication system is provided. One or more traffic parameters is determined for each of the communication links, and a requirement for channel capacity for each of the communication links is predicted based on the one or more traffic parameter. A channel capacity is then assigned to the communication link based on the predicted requirement.
1. A method for assigning of channel capacity to communication links in a cellular communication system, the method comprising the steps of:
determining of one or more traffic parameters for each of the communication links,
predicting a requirement for channel capacity for each of the communication links based on the one or more of the traffic parameters, and
assigning of channel capacity to the communication links based on the predicted requirement;
whereby the predicting comprises:
comparing the one or more of the traffic parameters with one or more traffic parameter profiles of known protocols and/or applications,
selecting a best matching traffic parameter profile, and
predicting the requirement for channel capacity based on a typical requirement for channel capacity of the selected traffic parameter profile.
2. The method of claim 1 , whereby one or more of the following traffic parameters are determined for a communication link:
data throughput,
delay between two polling operations,
variance of the delay between two polling operations,
number of Bytes to be transferred in uplink,
Error control mode.
3. The method of claim 1 , whereby the cellular communication system is a time division duplex or time division multiple access system or code division multiple access system.
4. A method for assigning of channel capacity to communication links in a cellular communication system, the method comprising the steps of:
determining of one or more traffic parameters for each of the communication links,
predicting a requirement for channel capacity for each of the communication links based on the one or more of the traffic parameters,
determining points of time to perform a polling operation with respect to one of the communication links based on the predicted requirement for channel capacity of that communication link,
performing the polling operation,
assigning of channel capacity to the communication link based on the result of the polling,
whereby the step of predicting is performed by:
comparing the one or more of the traffic parameters with one or more traffic parameter profiles of known protocols and/or applications,
selecting a best matching traffic parameter profile,
predicting the requirement for channel capacity based on a typical requirement for channel capacity of the selected traffic parameter profile.
5. The method of claim 4 , whereby one or more of the following traffic parameters are determined for a communication link:
data throughput,
delay between two polling operations,
variance of the delay between two polling operations,
number of Bytes to be transferred in uplink,
Error control mode.
6. The method of claim 4 , whereby the cellular communication system is a time division duplex/time division multiple access system or code division multiple access system.
7. An access controller for controlling the access of contending terminals to channel capacity of a cellular communication system comprising:
means for determining of one or more traffic parameters for each of the communication links,
means for predicting a requirement for channel capacity for each of the communication links based on the one or more of the traffic parameters, and
means for assigning of channel capacity to the communication links based on the predicted requirements;
whereby the means for predicting performs the predicting by:
comparing the one or more of the traffic parameters with one or more traffic parameter profiles of known protocols and/or applications,
selecting a best matching traffic parameter profile, and
predicting the requirement for channel capacity based on a typical requirement for channel capacity of the selected traffic parameter profile.
