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. 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 (UE) connected to said access point (AP), the method comprising the following steps when the access point is inactive or on standby:

placing (S1) a plurality of data packets in a queue (S1), a data packet having a waiting time d at the expiration of which the packet is considered lost;

for each waiting time value d, determining (S2) the transmission time of the data packets having a waiting time d; and

if, for a waiting time d, a corresponding transmission time T_d is higher than said corresponding waiting time d, the duration d−

Td thus being negative, the method comprises a step of activating (S4) said access point in order to transmit packets from the queue, the transmitted packets preferably being those having a low waiting time.

2. Method according to claim 1, in which the access point is configured for transmitting at least one data packet during a transmission interval (TTI), the transmission times Td corresponding to a whole number transmission interval (TTI) for transmitting the packets having a waiting time d.

3. Method according to claim 2, in which in each transmission interval it is possible to transmit the data packets over several frequencies.

4. Method according claim 1, in which the transmission time Td is a function of the duration necessary to activate the access point.

5. Method according to claim 1, in which the transmission time Td is a function of the quality of the radio link between a communication terminal and the access point.

6. Access point of a communication network configured for supplying data packets, at least one communication terminal (UE) connected to said access point (AP), the access point being moreover suited for implementing a method according to claim 1.

7. Communication network comprising at least one access point according to claim 6.

8. Communication network according to the claim 7, in which the access point is that of a 3GPP network of the Edge, 3G, 3G+, 4G, LTE type or of a non 3GPP network, of the Wi-Fi, Wimax type.

9. Computer programme product comprising code instructions for the execution of a method according claim 1, when said method is executed by a processor.
