CONTEXT MANAGEMENT

摘要

Systems, methods, and apparatus embodiments are described herein for context information management at the medium access control layer. In one embodiment, a system comprises a plurality of peers which communicate via peer-to-peer communications. In the system, context information may be exchanged at the MAC layer. Examples of context information include, without limitation, location information, mobility information, device capability, user information, an application category, multi-hop information, a channel condition, application information, association identifiers, and device information. Each of the plurality of peers may include a context manager that resides on each peer device. For example, a first context manager that resides on a first peer of the plurality of peers may exchange context information with a second context manager that resides on a second peer of the plurality of peers. In another example embodiment, the first peer, and in particular the first context manager that resides on the first peer, can retrieve the context information from a layer that is different than the MAC layer.

主权项

1. In a system comprising a plurality of devices that communicate via peer-to-peer communications and that each include a respective context manager, a method comprising, at a first context manager of a first device of the plurality of devices:
receiving a context information request frame comprising one or more parameters, the one or more parameters indicative of at least one of a list of context operations, a list of context identities, or a response type; and generating, based on the context information request frame, one or more context information response frames indicative of at least one of a number of remaining responses, an acknowledgement requirement applicable to a select one of the one or more context frames, a list of operations applicable to the select one of the one or more context frames, a list of context identities applicable to the select one of the one or more context frames, or one or more context values.
