Abstract

The invention relates to a method for managing an access point of a communication network, said access point being suitable for supplying data packets to at least one communication terminal connected to said access point, said method comprising the following steps when the access point is inactive or on standby:

a plurality of data packets are placed in a queue, a data packet having a waiting time d at the expiration of which the packet is considered lost;

for each waiting time value d, the transmission time of the data packets having a waiting time d is determined; and if, for a waiting time d, a corresponding transmission time T_d is higher than said corresponding waiting time d, the duration d−T_d thus being negative, the method comprises a step of activating said access point in order to transmit packets from the queue, the transmitted packets preferably being those having a low waiting time.

Claims

1. A method for managing an access point of a communication network, the access point being suitable for supplying data packets to at least one communication terminal connected to the access point, the method comprising:

placing a plurality of data packets in a queue, wherein one or more of the data packets have a waiting time, and wherein each of the data packets having a waiting time is considered lost at the expiration of the waiting time;

determining a transmission time of each of the one or more data packets having a waiting time, wherein each of the transmission times is a function of a duration necessary to activate the access point and a duration necessary to retransmit one or more data packets from an access point to a communication terminal; and

activating the access point in order to transmit one or more data packets in the queue if a waiting time of a data packet in the queue is higher than a transmission time of that data packet.

2. The method according to claim 1, wherein the access point is configured to transmitting at least one data packet during a transmission interval, and wherein each of the transmission times of the data packets corresponds to a whole number of transmission intervals.

3. The method according to claim 2, wherein in each transmission interval it is possible to transmit one or more data packets over several frequencies.

4. The method according to claim 1, wherein each of the transmission times is a function of a quality of the a radio link between the communication terminal and the access point.

5. An access point configured for to:

place a plurality of data packets in a queue, wherein one or more of the data packets have a waiting time, and wherein each of the data packets having a waiting time is considered lost at the expiration of the waiting time;

determine a transmission time of each of the one or more data packets having a waiting time, wherein each of the transmission times is a function of a duration necessary to activate the access point and a duration necessary to retransmit one or more data packets from the access point to a communication terminal; and

activate in order to transmit one or more data packets in the queue if a waiting time of a data packet in the queue is higher than a transmission time of that data packet.

6. A communication network comprising at least one access point according to claim 5 and at least one communication terminal.

7. The communication network according to the claim 6, wherein the access point is part of a 3GPP network, such as Edge, 3G, 3G+, 4G, or LTE.

8. The communication network according to the claim 6, wherein the access point is part of a non 3GPP network, such as Wi-Fi or Wimax.

9. The access point according to claim 5, wherein each of the transmission times is a function of a quality of a radio link between the communication terminal and the access point.

10. The access point according to claim 9, wherein the access point is configured to transmit at least one data packet during a transmission interval, and wherein each of the transmission times of the data packets corresponds to a whole number of transmission intervals.

11. A non-transitory recording medium comprising instructions that, when executed by one or more processors, cause the one or more processors to:

place a plurality of data packets in a queue, wherein one or more of the data packets have a waiting time, and wherein each of the data packets having a waiting time is considered lost at the expiration of the waiting time;

determine a transmission time of each of the one or more data packets having a waiting time, wherein each of the transmission times is a function of a duration necessary to activate the access point and a duration necessary to retransmit one or more data packets from an access point to a communication terminal; and

activate the access point in order to transmit one or more data packets in the queue if a waiting time of a data packet in the queue is higher than a transmission time of that data packet.

12. The non-transitory recording medium according to claim 11, wherein each of the transmission times is a function of a quality of a radio link between the communication terminal and the access point.

13. The non-transitory recording medium according to claim 12, wherein the access point is configured to transmit at least one data packet during a transmission interval, and wherein each of the transmission times of the data packets corresponds to a whole number of transmission intervals.
