Abstract

The present invention relates to a method of generating a message by a station in a network in which stations 5 transmit by intervals (A) for reporting to other stations (B) of reservations of a medium in an interval, wherein the station: —generates a set (10) of reservation information elements (A.1-A.n) wherein each reservation information element (A.1-A.n) identifies one of said reservations in the interval; and —creates at least one message (21-24) containing reservation information elements (A.1-A.n); —transmits the message to other stations (B).

Claims

1. In a network including stations that transmit in intervals, a method of generating a message by a station for reporting to other stations about reservations of a medium in an interval, the method comprising:

generating reservation information elements, wherein each reservation information element identifies one of the reservations in the interval; and

creating a plurality of messages containing the reservation information elements in order to distribute the reservation information elements to the plurality of messages.

2. The method according to claim 1, wherein the network is a wireless mesh network according to IEEE 802.11s standard, and the station is a mesh point.

3. The method according to claim 1, further comprising distributing at least one of the reservation information elements in more than one message in the plurality of messages.

4. The method according to claim 3, wherein the at least one of the reservation information elements contained in more than one message is repeated in some of the plurality of messages according to a predetermined repetition rate.

6. The method according to claim 16, wherein an information contained in each one of the reservation information elements is a difference between a first reservation information identifying the current reservation and a second reservation information identifying a previous reservation.

7. The method according to claim 16, wherein the reservation information elements are ordered in the message according to a change between the current and previous reservations.

10. The method according to claim 1, wherein the reservation information elements identify reservations done by neighbouring stations.

11. The method according to claim 1, wherein the message is a beacon frame.

16. The method according to claim 1, wherein the message includes only the reservation information elements that changed since previous reservations.

17. The method according to claim 1, further comprising transmitting the message to other stations.

18. A station for generating a message in a network to indicate a reservation of a medium, comprising:

a transmitter for transmitting data in intervals; and

a processing unit for generating reservation information elements, wherein each reservation information element identifies one of the reservations in the interval, the processing unit creating a plurality of messages containing the reservation information elements in order to distribute the reservation information elements to the plurality of messages.

19. A computer-readable storage medium having stored executable instructions for generating a message in a network to indicate a reservation of a medium, when executed, the acts comprising:

transmitting data in intervals;

generating reservation information elements, wherein each reservation information element identifies one of the reservations in the interval; and

creating a plurality of messages containing the reservation information elements in order to distribute the reservation information elements to the plurality of messages.
