    摘要: A method and apparatus for improved idle handoff a mobile station in a wireless communication system. While idling in a particular sector of the system, the mobile station will select a target sector based on a determination that the target sector has the same number of channels as the current sector, such as the same number of paging channels and perhaps the same number of frequency channels as the current sector. The mobile station will then engage in an idle handoff from the current sector to the selected target sector. By striving to hand off to a sector that has the same number of channels, particularly the same number of paging channels, the mobile station may avoid having to hash onto a channel in the target sector and may thereby minimize the likelihood of missing a page message sent while the mobile station was busy hashing onto the channel.

    摘要: A method and system for dynamically controlling the transmission of reverse-link control signals to help reduce interference on the reverse link. A RAN identifies a mobile device whose transmission of reverse-link control signals best represents the reverse-link air interface condition of each other mobile device in a plurality of mobile devices. Then the RAN causes each mobile device in the plurality other than the identified mobile device to not send its respective reverse-link control signal at a given time, thereby reducing the number of mobile devices that transmit reverse-link control signals at the given time.

    摘要: A first wireless network serves a wireless device and generates loading information. A second wireless network also serves the wireless device and also generates loading information. The first and second wireless networks share a plurality of wireless access points. A paging system receives a page request for the wireless device for delivery over the first network. The paging system processes the loading information to determine if paging assistance from the second network is applicable. If so, the paging system transfers a first page to the second network for delivery to the wireless device. The paging system receives a page response from the wireless device over the second network and processes the response to identify the shared wireless access point serving the wireless device. The paging system transfers a second page to the first wireless network for delivery to the wireless device through the identified shared wireless access point.

    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: 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.
