Abstract

A method and an apparatus in a short range wireless communication stores a list of keywords and a type list of information indicative of content and services available at an Access Point. A user terminal creates and stores a similar list of keyword and types. The user requests the keyword and types from the Access Point. This list is transmitted to the user within the service discovery protocol during connection set-up. The user Keyword list and Types are matched to the Access point Keywords and Types list to determine if a session should be established or terminated. The Access point may also connect to the terminal to obtain a list of the terminal Keywords and Types to determine if content is available to push to the terminal.
