    摘要: In a wireless network or other communication system, admission of users to the system involves use of a first scheduler, which makes actual scheduling decisions for admitted users, and a second scheduler, which emulates the operation of the first scheduler. The first scheduler is configured to manage access to network resources for users already admitted to the system. The first scheduler is coupled to an admission control module which contains the second scheduler. The second scheduler, also referred to herein as a virtual scheduler, emulates operation of the first scheduler, under an operating scenario involving admission of at least one additional user to the system, in order to generate a performance metric. The performance metric is used to make an admission control decision regarding admission of the at least one additional user to the system.

    摘要: A method for locating a mobile device in a wireless communications system comprised of a plurality of base stations is provided. The method comprises associating the mobile device with a first base station of the plurality of base stations. Thereafter, a paging signal is delivered from a subset of base stations associated with the first base station to the mobile device. The subset of base stations may correspond to a network active set of base stations associated with the mobile device. Thereafter, when a signal from one of the base stations in the subset of base stations is received, indicating that the mobile device responded to the paging signal from the one base station, then the mobile device is located and may be associated with the one base station for future paging attempts.

    摘要: A method and apparatus for scheduling data transmissions is disclosed that reduces the delay variability in transmissions of data. A scheduling metric is calculated as a function of a TCP throughput rate for each mobile terminal in the system. The relative value of this metric for a user is used to schedule data transmissions from that user. As a result, TCP time-outs are reduced or avoided and the throughput and the predictability of system performance are increased.

    摘要: A gateway for mobile access includes a foreign agent that receives user profile data and session state data from a home authentication, authorization and accounting (AAA) system of a mobile node, and a dynamic packet filter that performs multi-layer filtering based on the user profile data. The foreign agent transfers a session from a first network to a second network without session interruption, using the session state data, when the mobile node moves from the first network to the second network. The packet filter permits Internet access by the mobile node without passing Internet data requested by the mobile node through the first network.

    摘要: A radio link protocol (RLP)/point-to-point protocol (PPP) design is disclosed for wireless multimedia packet networks that passes corrupted packet data and error location information among OSI layers. The RLP layer provides erasure data frames and optionally error location indicators to the PPP layer. When the PPP layer has access to the erasure data frames, the data frames can be padded with a predefined value, such as all zeroes “0” to prevent error propagation from one data frame (or octet) to the following data frames (or octets). When the PPP layer has access to the error location information, the PPP layer can detect if the PPP packet header is corrupted. When a valid header is detected, the PPP layer forwards the packet payload to the higher layers (TCP, UDP) whether or not the payload is properly received. Thus, the application has access to all the usable information, so the application can determine whether and how to utilize the information. The RLP/PPP design of the present invention allows packets with partially corrupted payloads to still be forwarded to the UDP layer and then to the application layer.

    摘要: A complete User Datagram Protocol (CUDP) is disclosed that reduces packet loss. Channel frame error information is used with a packet level forward error correction (FEC) coding technique to accommodate wireless multimedia traffic. Each packet, as well as the channel frame error information, is forwarded to a given application. The CUDP protocol further assists the FEC decoding process by forwarding the locations of corrupted frames to the FEC decoder. Maximal Distance Separable (MDS) codes can be applied to a group of packets, to achieve additional robustness. An MDS decoder utilizes the frame error information to recognize the erasures within each packet. The error information can be represented as a set of LTU error indicators associated with each packet (for FEC decoders requiring an erasure indicator). The error indicators point to the starting and ending location of the erroneous data. The error information can also be represented as a reformatted packet (for FEC decoders Recognizing Erasures). The frame (LTU) error information from the lower layers is incorporated in the packet payload. An FEC encoder is also disclosed that encodes multimedia packets utilizing a packet-coding scheme, such as a Vertical Packet Coding (VPC) scheme or a Long Vertical Packet Coding (LVPC) scheme.
