摘要： A primary mobile station engaged in a communication session via a radio access network (RAN) may receive forward link communications over a forward link channel and transmit reverse link communications over a reverse link channel. If the quality of the communication session degrades, the primary mobile station may involve a secondary mobile station by establishing a short-range wireless communication link with the secondary mobile station, e.g., using Bluetooth™, IEEE 802.11, or other wireless communication protocol. The primary mobile station may then transmit reverse link communications to the RAN over the reverse link channel and also transmit the reverse link communications to the secondary mobile station, via the short-range wireless communication link, for transmission to the RAN. The RAN may receive the reverse link communications from the primary and secondary mobile stations as two distinct reverse link signals, which the RAN may combine together to achieve a diversity gain.

摘要： Disclosed is a mechanism for efficient channel selection in a wireless communication system. A wireless communication device (WCD) receives from a radio access network (RAN) a channel list message that specifies channels on which the RAN communicates in a coverage area. Further, the WCD receives from the RAN for at least a given one of the channels an expected delta value indicating an expected difference in signal strength between that channel and another channel. The WCD may then take an actual measurement of signal strength on the other channel and apply the expected delta to predict a signal strength of the given channel. Based on the predicted signal strength being threshold low, the WCD may then select a channel other than the given channel on which to communicate with the RAN, and the WCD may then communicate with the RAN on the selected channel.

摘要： An inter-frequency handoff of a mobile station engaged in a call via wireless network is effected by gradually changing a carrier frequency of a forward link signal from a first-channel frequency, corresponding to a first frequency channel, to a second-channel frequency, corresponding to a second frequency channel. Initially, a first transmitter in the wireless network transmits the forward link signal in the first frequency channel. A second transmitter then transmits the forward link signal while changing the carrier frequency from the first-channel frequency to the second-channel frequency at a specified tuning rate. The tuning rate may be dynamically adjustable in response to requests from the mobile station. Once the second-channel frequency is reached, a third transmitter continues transmitting the forward link signal in the second frequency channel. The mobile station may also gradually change the carrier frequency of the reverse link signal that it transmits for the call.

摘要： Methods and systems for providing an enhanced best-effort quality of service (QOS) are provided. As third-party real-time applications may be unable to explicitly signal QOS requests in some environments, this enhanced best-effort QOS may be applied to real-time flows associated with third-party applications. For instance, devices in an access network may determine that a packet is part of a real-time flow of packets, and is associated with a third-party application. In response to this determination, these devices may forward the packet according to the enhanced real-time QOS.

摘要： Disclosed are methods and systems for modifying a data-synchronization interval for an access terminal based on a number of access terminals being served by a wireless access point in a coverage area. In at least one embodiment, an access terminal periodically polls at least one network device via the access point for synchronization data according to a first data-synchronization interval. The access terminal receives from the access point information indicative of a number of access terminals being served by the access point in the coverage area. The access terminal determines a second data-synchronization interval based at least in part on a comparison of the number to a threshold value. Subsequent to determining the second data-synchronization interval, the access terminal periodically polls the at least one network device for synchronization data according to the second data-synchronization interval.

摘要： Methods and systems are provided for using mobile-station revision ratio to improve reverse-link performance. An access node provides service to first and second subsets of access terminals, the first operating according to IS-856, Rel. 0, the second according to IS-856, Rev. A. The access node periodically transmits a reverse activity bit (RAB) to the access terminals, and also periodically computes a ratio of (a) either (1) the number of access terminals in the first subset or (2) the number of access terminals in the second subset to (b) a total number of access terminals in the first and second subsets, and transmits the ratio to at least the first subset. When the RAB is set, the access terminals in the first subset perform a ratio test by comparing the ratio with a threshold, and decrease their reverse-link data rates without reference to any reverse-link transitional probabilities when the computed ratio passes the ratio test.
