摘要:
A method and apparatus for implementing path-based traffic stream (TS) admission control in a wireless mesh network having a distributed and/or centralized admission control architecture is disclosed. When the wireless mesh utilizes distributed admission control architecture, a source mesh point (S.MP) transmits a request for TS admission requiring certain resources/quality of service (QoS). The request propagates through the wireless mesh network until the destination mesh point (D.MP) is reached and an admitted path is determined. If an intermediate mesh point (MP) is unable to meet the requested resources/QoS for the TS, the S.MP is notified. When the wireless mesh network utilizes centralized admission control architecture, a S.MP requests a route to the D.MP from a central controller. The central controller maintains a status of MPs in the wireless mesh network, and selects a best route to handle the TS to satisfy the requested resources/QoS.

In a wireless communication system comprising a plurality of mesh points (MPs), a method and apparatus for transmitting management information includes a first MP transmitting a management frame to a second MP, wherein the management frame includes the medium access control (MAC) address of a destination MP. The second MP receives the management frame from the first MP and determines if it is the destination MP. The second MP updates the management frame if the second MP determines it is not the destination MP, and transmits the management frame to a third MP. The transmissions terminate when the data reaches the destination MP.

A multi-node communication system and method used to request, report and collect destination-node-based measurements and route-based measurements is disclosed. The communication system may be a mesh network including a plurality of mesh points (MPs). In one embodiment, a destination-node-based measurement request is sent to one or more destination nodes via destination-unicast, destination-multicast, or destination-broadcast, using routes specified via next-hop-unicast, next-hop-multicast, or next-hop-broadcast addressing. In another embodiment, a source node sends a measurement request message to a final destination node, whereby each node along the route individually sends a measurement report message to the source node. Alternatively, measurement results of each node are combined and appended to the measurement request message, and a measurement report message including the combined measurement results is sent to the source node.

The present invention integrates resource allocation between time division duplex (TDD) and frequency division duplex (FDD) in wireless communication systems. A radio network controller (RNC) receives a radio access bearer (RAB) request from a core network or a wireless receive/transmit unit. The RNC utilizes a TDD-FDD selector to assign radio resources in response to the request. The TDD-FDD selector evaluates various parameters regarding the received RAB request and determines whether it is preferable to assign TDD resources or FDD resources and whether such resources are currently available. Once resources are assigned, system conditions are evaluated to determine whether optimizations may be made to a current resource allocation.
