Abstract: A method for management of real-time system algorithms to achieve optimal efficiency which provides for dynamically managing priorities in a complex real-time system, considering the dynamic requirements of the system. A preferred embodiment describes the management of a plurality of RRM algorithms, including algorithms for SCC escape, LM escape, SCC rate control, and F-DCA background. More specifically, one exemplary embodiment assists in deciding: when to increase algorithm priorities, how to increase/decrease algorithm priorities, how to assign priority parameters, and how to dynamically manage priorities in the system, to result in optimal system efficiency.

Abstract: 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.

Abstract: A method and system for managing radio resources in a time-slotted wireless communication system is based on the quality of service (QoS) information of a user. A plurality of time slots of a radio resource are sorted into a plurality of different categories, such as high QoS time slots, high capacity time slots, and balanced time slots (305). Each category is associated with a different level of QoS. QoS information with respect to a user is obtained in response to a radio resource request received from the user (310). The user is associated with a particular category of time slots based on the QoS information of the user (315).

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: A method and system for performing dynamic link selection (DLS) between transmit/receive units (TRUs). A first TRU determines whether a second TRU has multiple interfaces with a DLS capability. If the second TRU has multiple interfaces with the DLS capability, the first TRU sends a packet to the second TRU through a selected link. The first TRU then receives a report from the second TRU and evaluates quality of the link based on the report. The first TRU selects a link for a new packet in accordance with a predetermined criteria and the quality of the link. If the second TRU does not have multiple interfaces with the DLS capability, the first TRU periodically sends probe packets to the second TRU via all available links. The second TRU sends response packets and the first TRU evaluates the quality of link based on statistics of the response packets.

Abstract: The present invention relates to a method for confirming the delivery of a data packet in a mesh network (100) by sending an acknowledgement to an ingress mesh point (104-4). A mesh network (100) comprises a plurality of mesh points (104) that are wirelessly linked together. A data packet sent by a station is received by an ingress mesh point (104-4). A MAC frame (200) is generated for transmission of the data packet and the frame is forwarded to an egress mesh point (104-2) in order to provide a service by the mesh network. The MAC frame (200) includes a field comprising an ingress mesh point address (206) and an egress mesh point (208) address. When the egress mesh point (104-2), receives a data packet successfully, the egress mesh point (104-2) or the intermediate mesh point (104-5) sends an ACK to the ingress mesh point (104-4) or preceding mesh point.

Abstract: A communication method, system and components are provided that includes use of traffic predictions determined by a wireless transmit/receive unit (WTRU). Preferably, the invention is implemented by predicting traffic in a wireless local area network (WLAN), between a WTRU and a WLAN access point (AP) that begins by determining a traffic level at the WTRU. Traffic prediction information is sent by the WTRU to the AP where it is used in conjunction with the generation of commands sent to WTRUs to control the manner of access by WTRUs to the WLAN via the AP. WTRUs receive instructions as to admission and are preferably configured to receive and implement instructions to adjust the contention window used by the WTRU to transmit data.

Abstract: A method for call admission control in a fast dynamic channel allocation wireless communication system begins by requesting that a call be admitted. System measurement results are obtained and timeslot sequences are generated by determining a figure of merit for each timeslot. A code set is determined and an attempt is made to assign a code set to a timeslot sequence, wherein each successful assignment is considered to be a solution. The solution having the lowest weighted total interference signal code power is selected, and codes are allocated for the selected solution. The physical resource allocation information is recorded and a response to the call admission request is issued.

Abstract: A wireless communication system including at least one IEEE 802 multi-stack wireless transmt/receive unit (WTRU) and a plurality of technologically diversified acess networks, such as IEEE 802.X networks and Third Generation Partnership Project (3GPP) networks, that are concurrently deployed. Both the multi-stack WTRU and the technologically diversified networks includ a media indipendent handover (MIH) function. The WTRU is configured to read MIH information transmitted from one of the IEEE 802.X networks, trigger 3GPP authentication and atuhorization procedures based on the MIH information, obtain a local Internet Protocol (IP) address, establish a tunnel to a packet data gateway (PDG) un a 3GPP core network, constructed a care of address (CoA) and register the CoA with a home agent of the WTRU, whereby data destined for the WTRU is routed via the home agent through a new tunnel established between the home agent and a foreign agent based on the CoA.
