摘要： A code-division multiple access power control for paging channel power and initial traffic channel power dynamically determines optimum initial channel power in accordance with pilot signal strength of a pilot signal as received at a mobile station and current forward link loading of the desired sector. The optimum initial paging channel power and initial traffic channel power may be determined either at a base station or a mobile switching center of the mobile communication system. A paging signal or call is transmitted from the base station to the mobile station over a paging channel and a traffic channel at the optimum paging channel and initial traffic channel power.

摘要： The present invention, in illustrative embodiments, implements systems and methods for adjusting the timing of access requests in mobile communications systems, such as IS-95-A mobile telephone systems, to reduce the likelihood of request collisions—especially during periods of very high calling rates. These embodiments employ measurements of access channel occupancy, as well as system operator inputs, to develop thresholds and parameter translations at a base station. Execution of control algorithms at a base station advantageously yields modified persistence test parameters sent to mobile stations. When overload conditions are present, these modified parameters cause the mobile stations to experience variable delays through judicious control of persistence testing at the mobile stations.

摘要： A method and apparatus for transmitting a burst of data over a supplemental channel on just one leg of a handoff by changing the maximum allowed burst duration of the data to be transmitted over the supplemental channel as a function of the future and/or current characteristics of the communication link of the leg(s) of the handoff. The data is then transmitted over just one leg of handoff using the maximum allowed burst duration. By changing the parameters of the data, the data may still be acceptably received at the mobile terminal over just one leg of the soft handoff even when the strength of the pilot signal used for the supplemental channel changes significantly. In an illustrative embodiment of the invention the stability of the communication link is used as a way of ascertaining the future conditions of the communications link.

摘要： A code-division multiple access base station assisted quality soft handoff algorithm screens or filters out candidate pilot signals from a pilot strength measurement message generated by a mobile station and provides the revised pilot strength measurement message to the mobile switching center of the mobile communication system. The mobile switching center subsequently conducts handoff processing in accordance with the revised pilot strength measurement message. If the combined pilot signal strength of the existing mobile station active legs is less than a first threshold, the current pilot strength measurement message is maintained. If the combined pilot signal strength of the existing mobile station active legs is greater than or equal to the first threshold, all candidate pilot signals are deleted from the pilot strength measurement message such that only pilot signals of existing mobile station active legs remain. Also, if the pilot signal strength of a candidate pilot signal is greater than a second threshold, the candidate pilot signal is added to the pilot strength measurement message. The number of handoffs per call are reduced using the revised pilot strength measurement message such that forward link power and network processing resources are conserved.

摘要： Call processing overload at a base station of a cellular wireless network is controlled by monitoring a level of call processing at the base station, and reducing a present handoff rate for active users when the call processing level exceeds a first threshold less than a maximum call processing capacity. When the call processing level at the base station exceeds a second threshold greater than the first threshold, a present rate of call originations or terminations is reduced while further reducing the handoff rate.

摘要： The Inter-System handover is one of the key features in the third generation cellular systems. The compressed mode, with variable transmission gaps and power levels, is standardized to support the inter-frequency system handover. To minimize the use of system resources while maintaining the border-cell handover quality, a capacity-based compressed mode control method of the present invention is proposed. Considering the tradeoff between the capacity and the communication quality, the control method can adaptively manage the compressed mode operation based on the potential impacts on the capacity and the effectiveness of the compressed mode measurement. The present invention will improve the effectiveness and performance of the compressed mode operation.

摘要： A communication system includes a base station and a plurality of remote stations wirelessly communicating with the base station. The base station determines a respective RF quality for each remote station. In response to a request for RF resources from a given remote station, the base station determines whether admission of the given remote station would exceed an RF power budget threshold. If the RF power budget threshold would not be exceeded, the RF quality is compared to a first quality threshold to determine whether to allocate the requested RF resource to the given remote station. Otherwise, the RF quality is compared to a second quality threshold more stringent than the first quality threshold to determine whether to allocate the RF resource to the given remote station. The base station may further determine whether to allocate requested RF resources on the basis of a priority of the requested resources.
