摘要： Disclosed herein is a method to condition removal of a carrier frequency from a wireless coverage area. The method involves evaluating handoff statistics for the coverage area, and applying results of past carrier frequency removal (preferably from a morphologically similar cluster) to predict a net change in hard handoffs that will result if the carrier frequency is removed. The method then involves using the predicted net change in hard handoffs as a basis to determine whether to remove the carrier frequency. The predicted net change in hard handoffs may be converted to a corresponding predicted net change in call drops, and the carrier frequency may then be removed only if the predicted net change in call drops does not exceed a threshold.

摘要： Disclosed in this document is an improved mechanism for notifying mobile stations that they should not seek to initiate a communication in a given wireless coverage area. The solution is to use a specially designated PN-offset as the indicator that a problem situation exists in the coverage area and that a mobile station should not seek to initiate communication in the coverage area. When a RAN detects a problem condition in a coverage area, the RAN changes the PN-offset of the coverage area to be a reserved PN-offset, and mobile stations are programmed to not seek service on any reserved PN-offset. Advantageously, the process helps stop mobile stations from operating in a problem coverage area without requiring the mobile stations to first lock onto the PN-offset of the coverage area and to then receive some sort of overhead message directing the mobile stations to not operate in the coverage area.

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： 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.
