Abstract: A method and wireless communication system for transferring management information is shown in figure 1B below. The system includes at least one access point (AP) (110) including a first management entity (150) and a seco nd management entity (155), and at least one wireless transmit/receive unit (WTRU) (105) including a third management entity (165) and a fourth manageme nt entity (170). The AP transmits a management information base (MIB) informati on 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 M IB information report action frame to the AP.

Abstract: A method and wireless communication system may be used for transferring management information. An access point (AP) may transmit a management information base (MIB) information request including a category field and an action details field to a wireless transmit/receive (WTRU). In response to receiving the information request, the WTRU may determine whether or not to provide management information to the AP. When the WTRU provides management information to the AP, the WTRU may compile management information stored in a MIB located in the WTRU and transmit a MIB information report to the AP. The MIB may list a plurality of tables containing information associated with radio resource management (RRM) and at least one table containing physical layer measurements. The AP may include a MIB for storing MIB information of the WTRU. The AP may transmit the stored MIB information of the WTRU in response to a request.

Abstract: A method for battery conservation in a wireless communication system begins with requesting a battery level measurement from a wireless transmit/receive unit (WTRU) (102) by a radio network controller (RNC) (104). The battery lev el is measured at the WTRU (102) and is reported to the RNC (104). The battery level measurement is stored in the RNC (104), where it can be accessed by radio resource management (RRM) (100) procedures. The battery level measurement is applied to the RRM (100) procedures by making adjustments to the procedures based on the battery level measurement, whereby the battery o f the WTRU (102) is conserved.

Abstract: A method for congestion control in the uplink of a wireless communication system having a wireless transmit/receive unit (WTRU) and a radio network controller (RNC) begins by receiving an interference report for each user. The average noise rise for each user calculated and congestion relieving measures are implemented based upon the average noise rise and the WTRU battery level. A method for congestion control in the downlink of a wireless communication system having a WTRU and a RNC begins by receiving a transmission power report for each user. The transmission power for each user is calculated, and congestion relieving measures are implemented based upon the average transmission power and the WTRU battery level.

Abstract: The present invention modifies existing media independent handover (MIH) function (MIHF) frame format as defined by the IEEE 802.21 standard. In one embodiment, the variable load of the MIHF frame is modified to eliminate the MIHF variable header by defining the MIHF identification (ID) field and the session ID field as fixed fields in the MIHF fixed header. Thus, the MIHF variable load is only made up of the MIHF payload. In another embodiment, a field such as an information element (IE), a header, or MIH service data such as a command or an event, is represented by a type field, a length field and a value field (TLV). The length of the value field is exactly 128 octets, and the length field only occupies one octet.

Abstract: A method and apparatus for performing a handover are disclosed. An Internet protocol (IP) multimedia subsystem (IMS) client registers with an IMS network and establishes a media independent handover (MIH) session with an MIH application server using a session initiation protocol (SIP). The IMS client establishes a session for IP-based service, (e.g., voice over IP (VoIP)), with a communication peer using an SIP. MIH messages are exchanged for handover with the MIH application server over IP. After handover, the session is resumed. A serving call session control function (S-CSCF) triggers the MIH application server based on a string “MIH services” and a unique identifier included in an INVITE request. The IMS client may send a REFER request to the MIH application server after the handover to resume the session. Alternatively, the IMS client may send a RE-INVITE request to the MIH application server and the communication peer.

Abstract: A method and apparatus for communicating slot allocations of nodes in a wireless mesh network that has data exchanges between the nodes occurring during slots. Each node maintains internal tracking of its slot allocation. A node may request a slot allocation of another node, and each node is enabled to report its slot allocation to other nodes. An information element (IE) and management type messages are introduced for tracking and reporting slot allocations among mesh network nodes.
