Content storing device query

摘要

A method, apparatus, and correspondingly configured computer program, in which a querying device inputs a user an identification of desired content and sends a query request for the desired content to surrounding memory devices. The query request is adapted to cause compatible receiving memory devices to perform a search based on the request. The memory devices are configured to listen to query requests and responsively perform searches based on the queries. Any memory device that finds content according to the query request responds to the query device which, after sending the query request, monitors for the compatible receiving memory devices for information that the queried content is found. Responsive to receiving the information from a given memory device, the querying device establishes a connection with the given memory device and obtains the content.

主权项

1. A method comprising, in a memory apparatus:
receiving from a querying apparatus, as a broadcast message over a wireless interface, a query request for desired content; performing a search based on the request; and if content according to the query request is found, responsively establishing a connection with the querying apparatus and informing the querying apparatus of the found content, and if no content according to the query request is found, responsively not establishing a connection with the querying apparatus for informing the querying apparatus of the result, wherein the query request is received as a broadcast message that is not addressed to any memory apparatus or set of memory apparatuses in particular, and further comprising scheduling of querying dynamically based on available power so that when available power suffices, simultaneous querying and data transmission to the querying apparatus are enabled and otherwise querying and data transmission of found content are performed sequentially.
