Abstract: Encoding secondary data with original data for providing robust responses to requests from wireless devices. As a server receives data from various sources for wireless device users, it saves the data, associates it with the corresponding users, and sets flags to provide an indication of the secondary data. When the server receives a request from a wireless device, it can respond to the specific request and check the status of the flags for the user to determine if secondary data exists. If it has secondary data for the user, it encodes that data with original data for generating a response. Upon receiving the response, the wireless device obtains both the data for the original request and the secondary data, or an indication of it, representing other data pending for the user and providing the user with the data without necessarily requiring that the user submit specific requests for it.

Abstract: Use of concepts to dynamically query a user and construct a sentence for responding to a user request. The use of hypertext concept notation permits the linking of related concepts through concept identifiers. The constructed sentence can be dynamically changed by a user selecting a representation of a concept within the sentence, either a complete sentence or one in the process of being constructed. The data for the selected concept can be updated and the new data inserted into the sentence using the links provided by the concept identifiers.

Abstract: Detecting local interactive wireless devices and an indication of services provided by or associated with them. A user's wireless device sends a ping signal based upon user input, a command from a server, or a command from another wireless device. The ping signal is used for short range wireless communication with other wireless devices. The other wireless devices within range receive the ping signal and transmit back a response. The user's wireless device assembles the responses into a structured format and can use them to display an identification of the wireless devices within the range or other information such as an indication of services of the wireless devices or services of entities associated with them. It can also transmit the responses to the server in order to obtain additional information about services within the range.
