ABSTRACT:
Methods, system and apparatus are provided for advertising service offerings in a communication system. An example embodiment comprises at least one device. A first device broadcasts a message of a first type, chooses a value for a time limit and listens for a message sent by a second device. If no message has been received before time limit, elapse, it again broadcasts a message of a first type. Otherwise, the message received from said second device is analyzed and if said message includes valid information about said first device chooses a value for the time limit. However, if said message received does not include valid service description about said first device, a message of a second type is broadcast. This reduces useless broadcast of a complete service list. Broadcast may be initiated more often and, service discovery for new devices coming into proximity takes less time.
