摘要:
A wireless communications network includes access points and wireless nodes. Each access point and each wireless node has a respective authentication token and address associated therewith. The access points and wireless nodes communicate using packets, where each packet includes an authentication token, an origination address and a destination address. During the communications, the access points read and store the respective authentication tokens and origination addresses in the packets wirelessly transmitted from the wireless nodes for defining an allowed wireless node list. Likewise, each wireless node reads and stores the respective authentication tokens and origination addresses wirelessly transmitted from the access points for defining an allowed access point list. The wireless nodes and access points do not associate with an attacker if both an authentication token and an address associated with the attacker are not on the respective allowed access point and wireless node lists.

An improved method of network management, particularly in the context of standards IEEE802.11 and IEEE802.11k, through two new MAC measurements, with attendant advantages. The two new measurements include WTRU uplink traffic loading measurement, and an AP service loading measurement and is generally applicable at least to layers 1 and 2 as applied to a least 802.11k in the context of OFDM and CDMA 2000 systems, but is applicable to other scenarios as well. A Method for determining and advertising congestion is also provided for a Wireless Local Area Network (WLAN) system. The present invention also introduces a method for managing congestion when congestion is detected. This aspect of the present invention applies primarily to wireless systems that use the Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) mechanism. The methods are advantageously implemented in selectively configured WTRUs of various forms.

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.

Independent delivery services to wireless terminals capable of supporting multiple radio interfaces is achieved through the employment of a service management center (SMC). The SMC determines the set of services and parameters based on the capability and service profile of the wireless terminal.
摘要:
A method and wireless communication system for transferring management information. The system includes at least one access point (AP) including a first management entity and a second management entity, and at least one wireless transmit/receive unit (WTRU) including a third management entity and a fourth management entity. The AP transmits a management information base (MIB) information request action frame including a category field and an action details field to the WTRU. In response to receiving the information request action frame, the WTRU determines whether or not to provide management information to the AP. When the WTRU provides management information to the AP, the WTRU compiles management information stored in a MIB located in the WTRU and transmits a MIB information report action frame to the AP. The MIB lists a plurality of tables containing information associated with radio resource management (RRM) and at least one table containing physical layer measurements.

A method and system is disclosed for providing assistance data to wireless transmit/receive units (WTRUs). The assistance data includes information regarding the access point's neighboring access points. The assistance data is transmitted to WTRUs using multicast and/or broadcast type signaling and facilitates ring and handover of WTRUs from one access point to another.
