A device and method for advertising service offerings in a communications network. A service offering includes information about the device making the advertisement, including what functions the device may serve. The advertisement also includes information about other devices in the network, when that information is available. Each device in the network determines a time value, at the end of which the device will send an advertisement. Each device listens for advertisements from other devices up to the time previously determined. If a device receives an advertisement that contains information about itself then the device will determine a new time value, at the end of which the device will send an advertisement. If a device receives an advertisement that does not contain information about itself then the device will send its own advertisement. |

DETAILED DESCRIPTION It is an object of the present invention to provide a scheme for introducing a new device into an ad-hoc wireless local network.
It is an object of the present invention to provide a scheme for a device in an ad-hoc wireless local network to announce its services to another device in the local network.
It is an object of the present invention to provide a scheme for a device in an ad-hoc wireless local network to discover services provided by other devices in the local network.
The present invention concerns an apparatus for exchanging service information with other devices.
The present apparatus comprises a transceiver, a processing unit, a memory for storing information about its local services and/or services provided by other devices, and a protocol resource manager.
This protocol resource manager performs the following steps.
It triggers the transceiver to send service information, comprising information about itself and/or other known devices to other devices.
It chooses a timeout value T.
sub.
A.
The protocol resource manager ensures that the apparatus listens for up to a maximum time T.
sub.
A for service information received by the transceiver.
If T.
sub.
A timed out without having received such service information by the transceiver, it triggers the transceiver to send service information, as stated above.
If such service information was received by the transceiver prior to T.
sub.
A timing out, the protocol resource manager checks whether the service information received comprises information about itself.
If it does, then it chooses another timeout value T.
sub.
A, and continues listening as stated above.
If the protocol resource manager does not find that the information received contained information about itself, it triggers the transceiver to send the service information, as stated above.
The present invention also concerns a scheme for advertising service offerings in a communications system comprising two devices.
The first device sends service information, comprising information about itself and/or other known devices
