    摘要: Methods and apparatus are provided for a wireless communication device (WCD) to utilize one or more search windows to capture both an earliest-received signal and a strongest received signal. In an embodiment, in a first time period, the WCD detects an arrival time of an earliest-received signal and an arrival time of a strongest received signal in one or more search windows for each of at least one set of signals. The WCD then centers a first search window based on the arrival time of the earliest-received signal and centers a second search window based on the arrival time of the strongest received signal for each of the at least one set of signals. In a second time period, the WCD searches for signals using the first and second search windows.

    摘要: A mobile station that is being served by a current sector receives a neighbor list that identifies a plurality of neighboring sectors and a respective priority for each neighboring sector. For each neighboring sector, the mobile station scans for the sector's pilot signal at a respective scanning frequency during a measurement interval. The scanning frequency for a sector defines how frequently the mobile station scans for the sector's pilot signal during the measurement interval. The mobile station selects a scanning frequency for a neighboring sector based on at least a signal strength of the current sector and the neighboring sector's priority. When the current sector's signal strength is high, the mobile station scans for high-priority sectors more frequently than low-priority sectors. When the current sector's signal strength is low, the mobile station scans for low-priority sectors more frequently than high-priority sectors.

    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: 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: Systems, methods, and software for wireless frequency changes for wireless communication devices based on tracking area updates in wireless communication systems are provided herein. In one example, a method of operating a communication system is provided. The method includes providing wireless access to communication services for wireless communication devices over a first frequency spectrum at a wireless access node, and receiving tracking area updates transferred by ones of the wireless communication devices. The method also includes processing at least a quantity of the tracking area updates received at the wireless access node to determine idle timers for the wireless communication devices, where an expiration of an associated idle timer indicates that an associated wireless communication device can no longer receive the wireless access over the first frequency spectrum and can receive further wireless access over a second frequency spectrum.

    摘要: A mobile station receives system time information from a source base transceiver station (BTS) in a spread spectrum communication system. The mobile station estimates a distance between the mobile station and the source BTS. The mobile station calculates a propagation delay based on the estimated distance. The mobile station develops a propagation-delay-adjusted time reference based on the system time information and the calculated propagation delay. The mobile station uses the propagation-delay-adjusted time reference to search for a target pseudonoise (PN) offset corresponding to a target BTS in the spread spectrum communication system. The mobile station may be closer to the target BTS than the source BTS.
