摘要:
A mobile station measures a pseudonoise (PN) offset and a signal strength of a spread spectrum signal transmitted by a given sector of a spread spectrum communication system. The measured PN offset differs from a nominal PN offset of the given sector. The mobile station transmits a measurement message that includes the measured PN offset and the measured signal strength. The spread spectrum communication system receives the measurement message and determines a location associated with the mobile station (e.g., based on location coordinates included in the measurement message). The spread spectrum communication system determines the nominal PN offset of the given sector based on the measured PN offset and the location associated with the mobile station. If the given sector is a valid handoff destination, the spread spectrum communication system transmits to the mobile station a handoff instruction that identifies the given sector by the measured PN offset.

In order to provide better wireless service to wireless communication devices (WCDs) at different altitudes (e.g., on different levels of a high-rise structure), a radio access network (RAN) may include antennas that are configured to provide coverage at these different altitudes. The RAN may assign resources, such as transmit power or frequencies, to wireless coverage areas serving particular altitude ranges in a proportion that is commensurate with the number of WCDs being served by these particular altitude ranges. As a result, RAN and WCD performance may improve.

In order to provide better wireless service to wireless communication devices (WCDs) at different altitudes (e.g., on different levels of a high-rise structure), a radio access network (RAN) may include antennas that are configured to provide coverage at these different altitudes. The RAN may assign an initial transmit power to a particular WCD based on the particular WCD's altitude. For instance, if the particular WCD is above a threshold altitude, the RAN may set the initial transmit power to the WCD to a lower value. However, if the WCD is below the threshold altitude, the RAN may set the initial transmit power to the WCD to a higher value, to overcome low-altitude signal obstructions. As a result, RAN and WCD performance may improve.
摘要:
In order to provide wireless service to wireless communication devices (WCDs) at different altitudes (e.g., on different levels of a high-rise structure), a radio access network (RAN) may include antennas aimed to direct coverage at different heights. The RAN may advertise the presence of wireless coverage areas that provide elevated coverage primarily to the WCDs above a threshold altitude. Similarly, the RAN may advertise the presence of wireless coverage areas that provide ground floor coverage primarily to WCDs below the threshold altitude. In this way, when a WCD is handed off to a new wireless coverage area, that wireless coverage area may be suited to provide coverage at the WCD's altitude.

In system and method of prioritizing a voice mail message, a voice mail message is received comprising caller information and chronological information, a voice mail priority is associated with the first voice mail message based on at least one of a matching criteria, a call history criteria, a chronological criteria, a frequency metric, and a missed call value, and a voice mail list is ordered according to the voice mail priority.
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.

Embodiments disclosed herein provide systems and methods for carrier frequency assignment based on transmit power differentials. In a particular embodiment, a method comprises determining first power levels of first carrier frequencies transmitted from a first wireless network base station and determining second power levels of second carrier frequencies transmitted from a second wireless network base station. The method further comprises determining transmit power differentials between the first power levels and the second power levels for corresponding ones of the first and second carrier frequencies. The method further comprises assigning a wireless communication device to one of the first carrier frequencies based on the transmit power differentials.

Disclosed are a method, apparatus, and system for managing repeat-paging processes within a radio access network. When a base station receives a paging directive, the base station begins broadcasting a first series of page messages destined to a mobile station. Response to the first base station receiving no response from the mobile station to the first series of page messages, the first base station sends a repeat-paging directive to a second base station. The repeat-paging directive directs the second base station to begin broadcasting a second series of page messages destined to the mobile station.
摘要:
Methods and systems for reducing the usage of non-preferred wireless coverage areas are presented. In particular, a RAN may determine that a WCD is likely to begin roaming. The WCD may be served by a preferred wireless coverage area and may be likely to roam to a non-preferred wireless coverage area. In an effort to avoid drawbacks associated with letting the WCD roam, the RAN may grant the WCD one or more forms of increased service quality. Doing so may prevent the WCD from roaming.
