Content storing device query
View Patent ↗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.
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.
2. 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, wherein the query request is embedded to a link layer command.
3. A memory apparatus comprising:
a receiver configured to receive, as a broadcast message over a wireless interface, from a querying apparatus a query request for desired content;
a memory comprising information content;
a processor configured to perform a search based on the request; and
a transmitter configured to:
establish a connection with the querying apparatus and
inform the querying apparatus of the found content responsively if content according to the query request is found, and if no content according to the query request is found, responsively not establish a connection with the querying apparatus for informing the querying apparatus of the result;
wherein the query request is configured to be received as a broadcast message that is not addressed to any memory apparatus or set of memory apparatuses in particular, and further configured to adapt the 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 the found content are performed sequentially.
4. A memory apparatus comprising:
a receiver configured to receive, as a broadcast message over a wireless interface, from a querying apparatus a query request for desired content;
a memory comprising information content;
a processor configured to perform a search based on the request; and
a transmitter configured to:
establish a connection with the querying apparatus and
inform the querying apparatus of the found content responsively if content according to the query request is found, and if no content according to the query request is found, responsively not establish a connection with the querying apparatus for informing the querying apparatus of the result;
wherein the query request is configured to be received as a broadcast message that is not addressed to any memory apparatus or set of memory apparatuses in particular, wherein the query request is embedded to a link layer command.
