摘要： Methods and systems are disclosed that may help a base station to adjust forward-link data rates in a given sector based on transmission-power variations in neighboring sectors. An exemplary method involves a base station that serves a first sector: (a) determining a respective transmission power for each of two or more channels of a second sector, (b) detecting a transmission-power difference between at least two of the channels of the second sector, and (c) in response to detecting the transmission-power difference: (i) determining a data rate control (DRC) adjustment for the first sector based at least in part on the transmission-power difference; and using the determined DRC adjustment to determine a forward-link data rate for at least one access terminal in the first sector.

摘要： A method and system is disclosed for control of discontinuous transmission based on vocoder and voice activity. An access terminal (AT) may engage in a communication session via an encoder-decoder in a network device in a wireless network. During silence intervals of the communication session, when the AT has no data to transmit, the AT may transmit periodic silence frames at a silence-frame rate to the encoder-decoder. The silence frames may contain parameters for generation of audio noise by the network device. Upon determining that the encoder-decoder has ceased transmitting data to the AT in response to a prolonged absence of transmissions from the AT, the AT may increase the silence-frame rate so as to reduce the duration of the absence of transmissions from the AT, and correspondingly cause the encoder-decoder to begin transmitting audio data to the AT.
摘要翻译：公开了一种基于声码器和语音活动来控制不连续传输的方法和系统。接入终端（AT）可以经由无线网络中的网络设备中的编码器 - 解码器进行通信会话。在通信会话的静默间隔期间，当AT没有要发送的数据时，AT可以以静默帧速率向编码器 - 解码器发送周期性的静默帧。静音帧可以包含用于由网络设备产生音频噪声的参数。在确定编码器 - 解码器已经停止向AT发送数据以响应于来自AT的延迟的传输的情况下，AT可以增加静默帧速率，以便减少不存在来自AT的传输的持续时间，并相应地使编码器 - 解码器开始向AT发送音频数据。

摘要： A method and system for managing broadcast of notifications indicating whether system information has changed, so as to enable served devices to determine when to read and store updated system information. A radio access network tracks changes in system information on a per wakeup cycle basis, so as to determine whether system information has changed since a last instance of broadcasting such a notification in a particular wakeup cycle. If system information has changed, the network responsively broadcasts an indication that system information has changed, so as to cause devices operating on that wakeup cycle to read and store the updated system information. Whereas, if system information has not changed, the network responsively broadcasts an indication that system information has not changed (or forgoes broadcasting an indication that system information has changed), so that devices operating on that wakeup cycle can avoid reading and storing the system information.

摘要： A method and system for dynamically adjusting reverse-link ACK transmission power based on forward-link timeslot utilization. A radio access network (e.g., a base station) may monitor timeslot utilization on the forward link and, upon detecting that the timeslot utilization is threshold high, may cause one or more served access terminals to increase their ACK transmission power, thereby possibly helping to minimize re-transmissions for data packets that have already been successfully received, and thus helping to minimize unnecessary use of potentially scarce forward-link timeslots.

摘要： A method and corresponding system is provided to help mitigate sector congestion. In one embodiment of the method, a RAN entity evaluates load among sectors of a tracking area and determines that the load is at least a threshold level of load. In response, the RAN entity enlarges the tracking area. In another embodiment of the method, when the RAN entity makes a decision to reconfigure a tracking area, it may consider one or more factors when determining how to reconfigure. In one example, the RAN entity may identify a particular border sector that has at least a threshold level of load or is a border sector in another network. Responsively, the RAN may reconfigure the tracking area such that the identified border sector is no longer a border sector. Other examples are possible.

摘要： In order to provide better wireless service to wireless communication devices (WCDs) at different altitudes (e.g., on different levels of a high-rise structure), a radio access network (RAN) may include antennas that are configured to provide coverage at these different altitudes. The RAN may assign resources, such as transmit power or frequencies, to wireless coverage areas serving particular altitude ranges in a proportion that is commensurate with the number of WCDs being served by these particular altitude ranges. As a result, RAN and WCD performance may improve.

摘要： A radio access network (RAN) may radiate to define a wireless coverage area that is configured to provide wireless coverage to wireless communication devices (WCDs). If the utilization of the wireless coverage area is below a low-utilization threshold, the RAN may begin transmitting noise frames in the wireless coverage area. In doing so, the transmitted signal strength of the wireless coverage area may increase, which in turn may increase the likelihood that the WCDs can acquire and use the wireless coverage area.

摘要： A radio access network (RAN) receives a request to route a call from a caller to a mobile station, assigns a wireless traffic channel to the mobile station for the call, and detects a no-answer condition for the call (because a user of the mobile station does not answer the call within a predetermined time period or has chosen to ignore the call). In response to the no-answer condition, the RAN redirects the call to a voice mail system and keeps the wireless traffic channel assigned to the mobile station while the caller interacts with the voice mail system. The RAN determines that the caller has left a voice mail message on the voice mail system and transmits an indication of the voice mail message to the mobile station over the wireless traffic channel.
