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 wireless communication device (WCD) may be able to acquire wireless service from preferred wireless coverage areas that are managed by the WCD's service provider. In some cases, the WCD may instead use wireless service from non-preferred wireless coverage areas of the service provider's roaming partners. In order to save roaming fees, the service provider's RAN may determine when the WCD is likely to roam to a non-preferred wireless coverage area. In response to this determination, the RAN may transmit a redirect message to the WCD, causing the WCD to switch from one preferred wireless coverage area to another preferred wireless coverage area. In some situations, the RAN may transmit such a redirect message because the WCD has reported that it has a low remaining battery life.
摘要翻译：无线通信设备（WCD）可能能够从由WCD的服务提供商管理的优选无线覆盖区域获取无线服务。在某些情况下，WCD可以改为使用来自服务提供商的漫游伙伴的非首选无线覆盖区域的无线服务。为了节省漫游费用，服务提供商的RAN可以确定WCD何时可能漫游到非优选的无线覆盖区域。响应于该确定，RAN可以向WCD发送重定向消息，导致WCD从一个优选的无线覆盖区域切换到另一个优选的无线覆盖区域。在某些情况下，RAN可以传送这样的重定向消息，因为WCD已经报告它具有低的剩余电池寿命。

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： Disclosed herein are methods and systems for managing usage of traffic-channel resources in an access network, which are preferably resources that are reserved during a traffic channel assignment (TCA) process. An exemplary method comprises (i) a base station determining a usage level of at least one traffic-channel resource in a coverage area of the access network; (ii) based at least in part on the determined usage level, updating one or more TCA parameters affecting expected usage of the traffic-channel resource resulting from the TCA process; and (iii) performing the TCA process according to the updated TCA parameters. Preferably the usage level is determined for Medium Access Control Identifiers (MAC_IDs). Further, the access-channel occupancy (ACO) may be determined and the base station may further base the updating of TCA parameters on the ACO. In an exemplary embodiment, the updated TCA parameters include the TCA count and/or the TCC wait timer.

摘要： A method and system for reducing latency by anticipating responsive data communications is described. When the user of a first mobile station receives a message sent from a second mobile station, the user of the first mobile station may responsively reply. If, before the reply is sent, the second mobile station releases its network radio link and goes dormant, the reply may be delayed as the radio link is set up again after the reply is sent. To reduce this latency, the first mobile station may monitor its user's actions and, upon an indication that the user intends to soon reply to the earlier received message, the first mobile station may send a signal into the network which causes the second mobile station to maintain its radio link or to set up a new radio link if it has gone dormant.

摘要： A first serving system that serves a first serving area receives a request to connect a call to a mobile station having a last reported location corresponding to a border area. The border area is proximal to a second service area that is served by a second serving system. The first serving system pages the mobile station in a first paging zone in the first service area. If the probability of successfully paging the mobile station in a second paging zone in the second service area is sufficiently high, the first serving system may also have the mobile station paged in the second paging zone by transmitting an inter-system page request to the second serving system. To determine the probability, the first serving system may look up a historical success rate for successfully paging in the second paging zone mobile stations having last reported locations corresponding to the border area.

摘要： Disclosed herein is a method and corresponding system to help a wireless communication device (WCD) stay within a home system's network coverage after an access attempt failure. According to one embodiment of the method, a WCD receives a channel list message (CLM) in a given coverage area and transmits an access attempt on a carrier listed in the received CLM. Upon the failure of such an access attempt, the WCD may transmit an additional access attempt on another carrier listed in the received CLM, rather than switching over to a roaming system. According to another embodiment, a WCD receives a channel list message (CLM) in a given coverage area and transmits an access attempt on a carrier listed in the received CLM. Upon the failure of such an access attempt, the WCD may transmit an additional access attempt on another carrier not listed in the received CLM, rather than switching over to a roaming system. According to yet another embodiment, a WCD receives a CLM from a first coverage area and thereafter moves into a second coverage area and subsequently receives a CLM from the second coverage area. The WCD transmits an access attempt on a carrier listed in the second CLM and upon the failure of such an access attempt, transmits an additional access attempt on a carrier listed in the first CLM.

摘要： During an initial part of a communication session, a transmitting node transmits digital data over a first air interface channel to a receiving node, using a first data rate and a first level of repetition. A degradation in quality of the communication session is detected. During a subsequent part of the communication session, the transmitting node transmits digital data over the first air interface channel as before but also transmits the digital data over a second air interface channel, using a second data rate and a second level of repetition. The second data rate is higher than the first data rate, and the second level of repetition is higher than the first level of repetition. Thus, during a given transmission period, the transmitting node may transmit a voice frame once over the first air interface channel and N times over the second air interface channel.
