摘要： An access network may be maintaining data indicating which of its coverage areas have a short occupancy time. The access network may then conduct a first paging of an access terminal in each coverage area in a first set of coverage areas, the first set including a subset of coverage areas having a short occupancy time. Thereafter, the access network may determine that it has not received a response to the first paging from the access terminal during a first timeout period, which is preferably shorter than a predefined paging timeout period. In response, the access network may conduct a second paging of the access terminal in only each coverage area in the subset of coverage areas (i.e., the coverage area(s) in the first set of coverage areas that have the short occupancy time).

摘要： Disclosed is a method and system to help reduce the extent of roaming or use of lower priority coverage areas in a wireless communication system, by selectively managing the level of noise in a preferred coverage area. A network entity will detect that a particular coverage area has a high rate or roaming or that another coverage area (e.g., a collocated or adjacent coverage area) has a high rate of use, and the network entity will responsively reduce a noise threshold in the particular coverage area so as to then tolerate less noise in the coverage area before taking affirmative action to reduce the level of noise, and thus optimally to reduce the extent of roaming or use of less preferred coverage.

摘要： A multi-mode mobile station is able to communicate with a first system using a first air interface protocol (e.g., EVDO) and with a second system using a second air interface protocol (e.g., 1×RTT CDMA). When the first system schedules a page message for transmission to the multi-mode mobile station, the first system may query the second system to determine whether the second air interface protocol is being used for a current call involving the multi-mode mobile station or is being used to attempt establishment of a requested call to the multi-mode mobile station. In the case of a current call, the first system may wait until the call is released before transmitting the page message. In the case of an attempt to establish a requested call, the first system may wait to determine whether the attempt is successful before transmitting the page message.

摘要： Disclosed is a method and system that involves establishing a communication between a wireless device and a base station notwithstanding, and in response to, a determination that the wireless device is threshold far away from the base station. When the base station or its supporting network infrastructure determines that the device is threshold far away from the base station, the base station will simultaneously establish the communication via the base station and at least one other base station. Once adequate communication then occurs through the other base station, the first base station will be dropped from the communication, allowing the communication to proceed though the other base station.

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 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： A radio access network (RAN) may transmit on a plurality of channels, each channel made up of a plurality of subcarriers. Each subcarrier defines a sequence of frames, each frame respectively defining a sequence of time slots. The RAN may transmit symbols in each time slot at at least a nominal power level on each of the subcarriers. The RAN may also determine a subcarrier that is likely to cause adjacent carrier interference between a first wireless device and a second wireless device. The RAN may also transmit null symbols in a first time slot of an initial frame on the determined subcarrier with a power level less than the nominal power level. Additionally the RAN may transmit subsequent symbols with the respective power level of each of the subsequent symbols is successively increased for each subsequent timeslot, for at least the duration of the initial frame.
