摘要： Systems and methods are described that facilitate obtaining geolocation information describing the geographical location of a mobile device while the device is in idle mode, without requiring the device to awaken and connect to an access network. A request for geolocation information is transmitted to the mobile over a control channel, and a geolocation report including geographical coordinates (latitude, longitude, altitude, etc.) is received from the mobile over an access channel. In this manner, the no user action, or user knowledge of the geolocation report, is required to obtain the report.

摘要： Example embodiments are directed to a system and methods of pre-registration, storing of pre-registered session information and session transfer, which may occur when an access terminal is in close proximity to a border area between a first radio access technology (RAT) area and a second RAT area. A method includes obtaining pre-registration session information if an access terminal enters a pre-registration zone, starting a pre-registration session information timer associated with the obtained pre-registration session information, and storing the obtained pre-registration session information until the associated pre-registration information timer expires. Further, both an access terminal and an access network include one or more memories configured to store more than one group of pre-registration session information and more than one timer. Each of the timers are associated with a corresponding set of pre-registration session information.

摘要： A closed loop power control based on receiving a continuous quality feedback is described. A main reverse link (RL) pilot is controlled by the quality feedback of a substantially continuous delay-sensitive traffic stream, such as Voice-over-IP (VoIP), when such a stream is enabled. When such a stream is not enabled, the quality of a continuous RL overhead channel is used to control the pilot power. At the same time, the Traffic-to-Pilot Ratios (TPR) of contemporaneously transmitted delay-sensitive data streams are independently adjusted based on a quality feedback associated with each such data stream.

摘要： In an H-ARQ system, when transmission on the FL MAC channel of DRCLock or CQILock bits is eliminated, other feedback information carried by the FL MAC channel is used as an RL quality indication for determining at least in part when to make a serving sector switch from a current serving sector to a non-serving sector in its active set. In particular, when data traffic is present, the ACKs/NAKs fed back to the AT on the FL MAC channel are used at least in part in determining when to make such a serving sector switch. In systems operating in accordance with CDMA2000 EVDO RevA/RevB standards, for example, this information is used in conjunction with quality measurements on the FL in determining when to make a serving sector switch. In future systems operating in accordance with CDMA2000 EVDO RevC standards currently under development in which the RL can be switched independently of the FL, this information is directly used to determine when to make an RL serving sector switch.
