摘要： A method and system is disclosed for shifting the phase of a PN long code for access attempts by an access terminal in a wireless communication network. An access terminal may seek to acquire access from a base station that is detected by the access terminal above a threshold power level, even if the access terminal is further away from the base station than a threshold distance beyond which access is not normally granted. According to one embodiment, the access terminal will, upon determining that it is beyond the threshold distance, embed in an access request message an apparent distance that is smaller than the threshold distance, by phase-shifting a timing signal and encoding the access request message with the phase-shifted timing signal. The access terminal will then transmit the access request message on an air interface communication link to the base station.

摘要： System and methods for generating and transmitting dynamic route-update-radius parameters are described. The parameters are dynamic in that the parameters may be modified from time-to-time. Modification of the parameters may be triggered by a radio access network (RAN) determining that a coverage area formed by the RAN is handling more than a threshold amount of communications to and/or from access terminals operating in the coverage area. The RAN may transmit the dynamic route-update-radius parameters so as to prevent some access terminals from registering with the coverage area while the coverage area is handling more than the threshold amount of communications. While the coverage area is handling a reduced amount of communications, such as less than a threshold amount of communications, the access network may transmit default route-update-radius parameters to coverage areas remote from that coverage area. The route-update-radius parameters may include a route-update-radius, a modified route-update-radius, and a route-update-radius offset.

摘要： Methods and computer-readable media are provided to determine which sector the mobile device will bias during soft handoff. Signals are received from multiple sectors, and for a first quantity of time slots of a frame, the signals are inspected to determine whether a quality threshold is met. Based on whether the quality threshold is met, each sector is assigned a power control command indicating that either a decrease or increase of output power is recommended when a subsequent signal is sent to the mobile device. For a second quantity of time slots, the overall power control command sent to the sectors corresponds to the power control command assigned to the sector that has communicated the highest quality signals for the first quantity of time slots of the frame.

摘要： Wireless access terminals operating in a radio access network (RAN) may move from one coverage area to another coverage area formed by base stations within the RAN. The RAN tracks the location of the access terminals so that RAN can efficiently route communications, such as page messages, to a base station serving the access terminals. From time-to-time, the access terminals can send route-update messages to inform the RAN of their locations. Sending the route-update messages can increase the loading on base station channels that carry the messages. Methods, systems, and devices for delaying transmission of the route-update messages are described. Delaying or not delaying transmission of the route-update messages may be dependent on occupancy of access channels of a base station and whether the access terminals are mobile at the time the route-update messages are to be sent.

摘要： During a communication session, a first BTS transmits a first forward link signal that is received by a first mobile station, a second BTS transmits a second forward link signal that is received by a second mobile station, the first mobile station transmits a first reverse link signal that is received by the first BTS, and the second mobile station transmits a second reverse link signal that is received by the second BTS. One or more control parameters for the forward and/or reverse link signals are selected based on a receiver sensitivity of the first mobile station and/or second mobile station. In one example, a target error rate of the first reverse link signal and a maximum transmit power level of the second forward link signal are selected based on the receiver sensitivity of the second mobile station.

摘要： Methods and systems are provided causing a mobile station to, after experiencing a dropped call, originate a subsequent call via a coverage area different than that used for the first call. In an embodiment, a mobile station detects that, when it was engaged in the first call at a first location via a first wireless coverage area, the mobile station experienced the first call being dropped. When the mobile station subsequently attempts to originate a second call, the mobile station determines that its current location is within a threshold distance of the first location, and responsively attempts to originate the second call via a second wireless coverage area different from the first.

摘要： Methods and systems for adaptive hybrid automatic repeat request (H-ARQ) protocols are disclosed. The protocols preferably adapt to changing network conditions between a client node and an access node by omitting the transmission of certain messages when network conditions are determined to be favorable. In doing so, packets are processed faster, thus reducing communication latency as well as the memory requirements of the protocols. One scenario in which the protocols may operate is where the client node is a wireless communication device coupled to the access node via a wireless network. In such a scenario, the access node may, from time to time, measure a quality of the wireless air interface between the client node and the access node, and determine whether to transmit an acknowledgement message based on the outcome of the measurement as compared to a threshold value.

摘要： An access network may receive an incoming communication for an idle access terminal having a last-known location in a first service area of the access network. In response to receiving the incoming communication, the access network may determine whether the last-known location is proximate to a border between the first service area and a second service area of the access network. If so, the access network may define a border paging area encompassing one or more coverage areas within the second service area that are proximate to the last-known location. In turn, the access network may determine a representative paging-channel occupancy of the border paging area. Based on the representative paging-channel occupancy, the access network may then select a time at which to initiate a border page of the access terminal in the border paging area and then perhaps initiate the border page at the selected time.

摘要： Methods and systems for efficiently using multiple paging channels in a wireless communication network are proposed. In particular, a radio access network (RAN) may determine that a wireless communication device (WCD), such as a cell phone, has not been responding to paging messages transmitted on a secondary paging channel. In response to this determination, the RAN may instruct the WCD to listen only to a primary paging channel, while the RAN will only use the primary paging channel to page the WCD. This, in turn, may increase the likelihood that the WCD is able to properly receive and respond to paging messages, and reduce the power consumption and battery drain of neighboring WCDs.
