摘要： A method, system and program product which improves the QoS and GoS of voice and data traffic on an integrated communications network. An RF spectrum allocation application/algorithm provides initial allocation of a percentage of available spectral resources to current voice and data traffic. Each allocated percentage is bounded by a sliding window, which adjusts its location based on the changing need for the resources. Thus, a voice sliding window dynamically adjusts its location to provide additional spectral resources to voice traffic when the voice traffic increases and provides less spectral resources when the voice traffic decreases. Likewise, a data sliding window dynamically adjusts its location to provide additional spectral resources to data traffic when the data traffic increases and provides less spectral resources when the data traffic decreases. The size of each window is determined by input parameters. When heavy voice and/or data traffic is present, the maximum available spectral resources are utilized and shared between both traffic types based on the RF spectrum allocation algorithm. Whenever an overlap in the windows occurs, the algorithm dynamically determines which of the traffic types to allocate the remaining spectral resources based on a number of factors, including the cost/financial factors and QoS and GoS calculations.

摘要： An ANC is formed to “dummy fill” a neighbor list that is to be transmitted to a mobile terminal that is presently located in a border cell with neighboring BTSs for which a hand-off request cannot be granted. Accordingly, while a hand-off cannot occur to a BTS of a proximate cell that does not qualify as a neighbor because it is serviced by a different ANC in a 1xEVDO network, identifying the BTSs of the non-neighbor and proximate cells (“dummy list BTSs”) prompts the mobile terminal to request a hand-off to a dummy list BTS when the BTS provides a better pilot signal. Because the ANC can readily identify the BTS from the dummy list, it knows that a hand-off cannot be facilitated therefor. Accordingly, the ANC instructs the mobile terminal to drop the call (data packet connection). Because many wireless data packet networks utilize at least a subset of established IP protocols and are able to establish point-to-point protocol communication links (higher layer communication links), commanding a mobile terminal to drop the call is a command to drop the call at the lower layers. The point-to-point protocol communication link is then resumed and the effect of a hand-off is achieved.

摘要： A method of connection setup in mobile wireless data communications systems is disclosed where the connection setup time is decreased for delay-sensitive communications sessions relative to the normal connection setup time for confidence-dependent communications sessions. This is achieved by performing some of the connection set-up steps for delay-sensitive communications sessions after successfully demodulating a smaller number of indications identifying an access terminal's desired serving resource than would be demodulated in the case of a confidence-dependent communication session prior to performing the same connection set-up steps.

摘要： An Optimized Streetlight Operation (OSLO) system that utilizes a cellular network overlay to broadcast control commands issued by a centralized Streetlight Operation Center (SOC) to RF control modules mounted on each streetlight pole. The cellular network may be a CDMA network utilizing Short Message Service-Broadcast (SMS-B) messaging. When a Mobile Telephone Exchange/Mobile Switching Center (MTX/MSC) receives a SOC control command from the SOC, the MTX/MSC causes a plurality of BSs to broadcast the SOC command in the network operating area a defined number of times. Each RF control module that successfully receives the broadcast SOC control command, performs actions to control operation of the module's associated streetlight, and transmits a confirmation message to the module's serving BS indicating the SOC command was received. The modules are configured to stagger transmission of the confirmation messages over a period of time to reduce a peak load imposed on the cellular network.

摘要： A method and apparatus for controlling a Network Load Balancing (NLB) algorithm that balances a traffic load between multiple downlink (DL) sectors in a cellular telecommunication network. A Connection Integrity Preservation (CIP) algorithm, which runs on top of the NLB algorithm in the Radio Network Controller/Base Station Controller (RNC/BSC), minimizes the risk of degrading network performance due to NLB offload decisions. The CIP algorithm may override an NLB offload decision, for example, if there have been too many offload failures, there are no target DL sectors available to acquire an offloaded Access Terminal (AT), or the offloaded AT is not acquired within a threshold time period. The CIP algorithm ensures required metrics are collected, and minimizes the impact on RNC/BSC processing due to Routing Update messages needed to make offload decisions. The invention enables the NLB algorithm to realize its potential without negative side-effects.
摘要翻译： 一种用于控制在蜂窝电信网络中平衡多个下行链路（DL）扇区之间的业务负载的网络负载平衡（NLB）算法的方法和装置。 在无线电网络控制器/基站控制器（RNC / BSC）中运行的NLB算法之上运行的连接完整性保护（CIP）算法最大限度地降低了由于NLB卸载决定而导致网络性能下降的风险。 CIP算法可以覆盖NLB卸载决定，例如，如果发生了太多卸载故障，则没有可用于获取卸载的接入终端（AT）的目标DL扇区，或者在阈值时间内未获取卸载的AT 期。 CIP算法确保收集所需的度量标准，并最大限度地减少由于进行卸载决定所需的路由更新消息对RNC / BSC处理的影响。 本发明使得NLB算法能够实现其潜在性而没有负面的副作用。
