摘要： A method is disclosed for disambiguating a reported pilot signal so as to facilitate handoff of a mobile station. When a radio access network (RAN) receives from a mobile station a handoff request carrying a parameter that ambiguously identifies at least two sectors as the potential handoff target, the RAN will send a test probe on at least one of the potential handoff target sectors and will determine, based on mobile station response to the test probe, which sector the mobile station received the test probe on and thus which sector was the intended handoff target. The RAN may then direct the mobile station to hand off to that sector if appropriate. Further, the RAN may add the identified sector into a neighbor list of a similarly situated other mobile station, to allow the other mobile station to more efficiently hand off to the same sector if appropriate.

摘要： Disclosed is a method and system for allocating power among concurrent transmission attempts from a radio access network (RAN). In practice, the RAN encounters a situation where the RAN is going to engage concurrently in at least a transmission attempt of a first message and a transmission attempt of a second message. The RAN then determines an attempt number of the first transmission attempt and an attempt number of the second transmission attempt. The RAN then compares the determined attempt numbers and, based on the comparison, allocated a limited quantity of transmission power among the first transmission attempt and the second transmission attempt. For instance, based the comparison a greater portion of the transmission power may be allocated to one of the transmission attempts and a correspondingly lesser portion of the transmission power may be allocated to the other transmission attempt.

摘要： Disclosed is a method and corresponding system to help improve inter-frequency handoff. While a radio access network (RAN) is serving one or more devices, the RAN will receive from the device(s) one or more reports of air interface quality on each of a plurality of potential target frequency channels. Dynamically based on the reported air interface quality information, the RAN will then select a given one of the potential target frequency channels to be a preferred target frequency channel. When a given device is fading from coverage, the RAN will then direct the device to scan for coverage on the preferred target frequency channel that was selected based on the earlier reported measures of air interface quality, so as to facilitate inter-frequency handoff.
