US 2020/0092696 A1 · MECHANISMS FOR RESOURCE-DIRECTORY TO RESOURCE-DIRECTORY COMMUNICATIONS

Abstract

An M2M/IoT resource directory entity may discover and register to other resource directory entities by including criteria attributes in discovery broadcasts and then processing link and metadata that may be included in responses. The resource directory with registrations to other resource directories may service a client request by selecting other resources directories to query based on the request or a query criteria contained therein, and then process link and metadata in responses from the other resource directory entities to aggregate a response to the client. Directory-to-directory registrations may be facilitated via using hierarchical parent-child resource directory identifiers, a peer-to-peer identifier regime, or a combination of the two. Observe notifications may include indicia registrations states, e.g., via change and delete response codes.

Claims20

Dependent claims

A first apparatus comprising a processor, a memory, and communication circuitry, the apparatus being connected to a communications network via its communication circuitry, the apparatus further comprising computer-executable instructions stored in the memory of the apparatus which, when executed by the processor of the first apparatus, cause the apparatus to:

implement a first resource directory;
receive, from a second resource directory, the second resource directory residing on a second apparatus, a registration request comprising a resource directory identifier of the second resource directory;
determine whether to register the second resource directory based, at least in part, on resource directory identifier of the second resource directory and a registration table;
and
register the second resource directory by adding a registration identifier of the second resource directory to the registration table;
and
send, to the second resource directory, a response to the registration request.

4 more elements

implement a first resource directory;
maintain a registration table comprising resource directory identifiers for multiple resource directories and data regarding resources available at the multiple resource directories;
receive, from a client, the client residing on a second apparatus and being an endpoint or a second resource directory, a request for a resource;
determine whether the resource is available at one of the multiple resource directories by examination of the registration table;
and
if the resource is not available within the first resource directory but is available at one of the multiple resource directories, send a response, to the client, providing a resource directory identifier for a resource directory having the resource.

3 more elements

A method for communications among resource directories, comprising:

receiving, by a first resource directory from a second resource directory, a resource directory discovery query comprising one or more discovery query attributes;
determining, by the first resource directory, whether to respond to the resource directory discovery query based, at least in part, on one of the discovery query attributes;
sending, to the second resource directory, a response to the resource directory discovery query comprising a resource directory identifier of the first resource directory and resource directory data, where the resource directory data is related to one or more of the discovery query attributes.

Dependencies are inferred from the claim text.
