Method for assigning uplink and/or downlink capacities based on available capacity
View Patent ↗A method is provided for use in communication involving first and second parties. The method includes determining a first capacity associated with a first channel of a communication link between the first and second parties. The method also includes assigning a second capacity to a second channel of the communication link based on the first capacity and a third capacity associated with at least the first and second channels.
1. A method for use in communication involving first and second parties, comprising:
determining, by a grant server configured to allocate channel capacities, a first capacity associated with a first channel of a communication link between the first and second parties, the first channel being either an uplink or a downlink channel;
negotiating, between the first and second parties, a maximum capacity allocated to the communication link; and
assigning a second capacity to a second channel of the communication link, the second channel providing communication in the opposite direction to the first channel, and the second capacity being assigned based on the first capacity and the maximum capacity allocated to the communication link such that the sum of the first and second capacities does not exceed the maximum capacity.
2. The method of claim 1 , wherein negotiating the maximum capacity comprises negotiating, between the first and second parties, contractual maximum capacity associated with said at least one uplink channel and said at least one downlink channel of the communication link.
3. The method of claim 1 , wherein the first channel comprises an uplink channel, and wherein determining the first capacity comprises measuring an uplink capacity associated with the uplink channel.
4. The method of claim 3 , comprising determining at least one of a minimum uplink capacity and a maximum uplink capacity associated with the uplink channel.
5. The method of claim 4 , wherein assigning the second capacity comprises assigning a downlink capacity based on the maximum capacity and at least one of the measured uplink capacity, the minimum uplink capacity, and the maximum uplink capacity.
6. The method of claim 1 , wherein the first channel comprises a downlink channel, and wherein determining the first capacity comprises measuring a downlink capacity associated with the downlink channel.
7. The method of claim 6 , comprising determining at least one of a minimum downlink capacity and a maximum downlink capacity associated with the downlink channel.
8. The method of claim 7 , wherein assigning the second capacity comprises assigning an uplink capacity based on the maximum capacity and at least one of the measured downlink capacity, the minimum downlink capacity, and the maximum downlink capacity.
9. The method of claim 1 , wherein assigning the second capacity comprises assigning the second capacity based on at least one of a number of users, a current load, a traffic shape, and a statistical multiplexing of traffic streams of different users.
10. The method of claim 1 , wherein assigning the second capacity comprises assigning the second capacity at a predetermined interval.
11. The method of claim 1 , wherein assigning the second capacity comprises assigning the second capacity such that the second capacity is less than or equal to the difference between the maximum capacity and the first capacity.
12. A method for use in communication involving first and second parties, comprising:
determining, by a transmitting device configured to transmit information over an uplink channel of a communication link between said first and second parties a first capacity of the uplink channel of the communication link between the first and second parties based on a second capacity associated with a downlink channel of the communication link and an available capacity allocated to the communication link such that the sum of the first and second capacities does not exceed the available capacity;
accessing information to be transmitted over the uplink channel at a fourth capacity; and
dropping a portion of the accessed information if the fourth capacity exceeds the first capacity.
13. The method of claim 12 , wherein determining the first capacity comprises determining the first capacity such that the first capacity is less than or approximately equal to the difference between the available capacity and the second capacity associated with the downlink channel of the communication link.
14. The method of claim 12 , wherein determining the first capacity comprises determining the first capacity of the uplink based on at least one of a minimum uplink capacity, a maximum uplink capacity, a number of users, a current load, a traffic shape, and a statistical multiplexing of traffic streams of different users.
15. The method of claim 12 , comprising transmitting a remaining portion of the accessed information over the uplink at approximately the first capacity.
16. A method for use in communication involving first and second parties, comprising:
determining, by a transmitting device configured to transmit information over a downlink channel of a communication link between said first and second parties a first capacity of the downlink channel of the communication link between the first and second parties based on a second capacity associated with an uplink channel of the communication link and an available capacity allocated to the communication link such that the sum of the first and second capacities does not exceed the available capacity;
accessing information to be transmitted over the downlink channel at a fourth capacity; and
dropping a portion of the accessed information if the fourth capacity exceeds the first capacity.
17. The method of claim 16 , wherein determining the first capacity comprises determining the first capacity such that the first capacity is less than or approximately equal to the difference between the available capacity and the second capacity associated with the uplink channel of the communication link.
18. The method of claim 16 , wherein determining the first capacity of the downlink comprises determining the first capacity of the downlink based on at least one of a minimum downlink capacity, a maximum downlink capacity, a number of users, a current load, a traffic shape, and a statistical multiplexing of traffic streams of different users.
19. The method of claim 16 , comprising transmitting a remaining portion of the accessed information over the downlink at approximately the first capacity.
