摘要： Systems and methodologies are described herein that facilitate congestion control in a wireless communication system. As described herein, an access network and associated terminals can utilize a token bucket access control mechanism, through which respective terminals can be allotted access tokens and/or other units for access to the access network. For example, upon requesting access to a given network, a user of the network can determine whether sufficient access tokens have been accumulated, based on which the request can be selectively allowed or denied. As further described herein, multiple token bucket mechanisms can be utilized, which can correspond to respective packet flows or the like. Additionally, token bucket access control can be implemented as described herein in cooperation with conventional access persistence functionality. Further aspects described herein facilitate the adjustment of token bucket parameters for network access control based on network loading.

摘要： Techniques for selecting a serving sector for a terminal based on server selection information in order to balance the load of sectors in a wireless communication system are described. The server selection information for each sector may be set based on the load of the sector and may be used to rank the sector for selection as a serving sector. In one design, a terminal may receive server selection information for multiple sectors. The server selection information for each sector may include an offset used to adjust a measurement made by the terminal for the sector, a priority of the sector for selection as a serving sector, a DRCLock set based on the load of the sector, etc. The terminal may determine received signal qualities of the sectors. The terminal may then select one of the sectors as a serving sector based on the server selection information and the received signal qualities of the sectors.

摘要： A method and apparatus for requesting Point-to-Point Protocol (PPP) instances from a packet data services network includes a mobile station configured to send an origination message to a packet data service node (PDSN) at which it has arrived upon leaving the vicinity of another PDSN. The message informs the new PDSN of the new location of the mobile station and indicates both the number of dormant PPP instances associated with the mobile station and a service reference identifier for each such PPP instance. A flag within the message may be used to indicate whether the PPP instances are dormant (i.e., whether the mobile station is engaged in a call). Communications channel resources of packet data services nodes are optimized by reducing the information included in messages from the Packet Control Function network element to the Packet Data Service Node network element, and by reducing the use of Mobile Internet Protocol agent advertisement.

摘要： Techniques for enhanced backhaul flow control are provided. In an exemplary embodiment, a backhaul control system is described that comprises a base station controller (BSC), a backhaul network, and a base transceiver station (BTS). Each is responsive to data and messaging transmitted and received. In one aspect, the BTS includes a queue and a controller. The amount of data in a queue is adjusted by a controller based upon calculating a target queue size value. The controller non-uniformly adjusts the amount of data in a queue based upon a target queue size value which is based upon communication system parameters. The target queue size and amount of data in a queue is adjusted so as to reduce buffer underrun, decrease system latency, and increase communication system throughput.

摘要： A novel method and apparatus is disclosed for performing seamless handoff of a mobile station (MS) between Radio Access Networks (RANs) that use different types of wireless interfaces. The described embodiments enable an MS to handoff between different RANs without causing routing ambiguity, and without substantial loss of network data. Upon moving from the coverage area of a first RAN using a first wireless interface to the coverage area of a second RAN using a second wireless interface, an MS determines whether routing ambiguity may result from the change of RAN and, based on the determination, triggers a re-registration of its network address. A foreign agent (FA) within a packet data serving node (PDSN) monitors network address re-registrations in order to determine whether multiple RAN-PDSN (R-P) connections are being created for the same MS. Based on this determination, the PDSN terminates redundant R-P network connections resulting from movement of the MS between different RANs.

摘要： This disclosure provides a method and apparatus for the communication of low delay data over multiple channels having different speed and latency and requiring a different amount of time to set up. In one embodiment, the transmitter removes duplicate data packets from a queue after a second channel, such as a dedicated channel is established. In an alternate embodiment, sequence numbers are assigned to data packets, allowing the receiver to identify duplicate packets and ignore the duplicates.

摘要： Techniques for synchronization of stored service parameters are disclosed. In one aspect, a configuration identifier is transmitted from a mobile station to a base station, and compared with an identifier generated in the base station. If the identifiers match, the configuration is used for communication. In another aspect, the identifier is generated by selecting an identifier associated with a configuration from a configuration table. In yet another aspect, the identifier is generated by computing a cyclic redundancy check (CRC) of the configuration. Various other aspects are also presented. These aspects have the benefit of preventing attempted use of unsynchronized stored service parameters and associated call setup failures and subsequent renegotiation, with the net effect of reducing call setup time and more efficient use of system resources.
