Methods and systems for mobile station location detection. A mobile station measures signal strength of each of a set of signals associated with the mobile station, then determines whether a number of signals in the set is less than a predetermined threshold. Based on the determination, the mobile station calculates a difference in power between a first and second signal associated with the mobile station. Thereafter, power on a channel corresponding to the mobile station is increased for a predetermined number of frames based on the calculation. The location of the mobile station is determined during the power increase.

A system assigns PN offsets in a network ( ) with multiple sectors ( ). The system sets parameters for the network ( ) and assigns PN offsets to the sectors ( ) based on the set parameters. The system then identifies sectors ( ) in the network ( ) that have poor network performance as a result of the PN offset assignments. The system changes parameters for the identified sectors ( ) and reassigns PN offsets to the sectors ( ) based on the changed parameters to improve network performance.

A system ( ) provides a network designer with a mechanism by which to quickly estimate the performance of a code division multiple access wireless communication network. The system ( ) allows the designer to enter a group of network and sector parameters. Based on these parameters, the user can choose one of three methods depending on a desire for speed, accuracy, and generality of result.

A system optimally assigns pseudo-noise (PN) offsets in a cellular network that includes several sectors. The system sets parameters for the cellular network, determines potential interference between each of the sectors and mobile units in the cellular network based on the set parameters, and identifies constraints for each of the sectors based on the determined potential interference. The system then approximates a highest co-offset protection value for successful PN offset assignments based on the determined potential interference and the identified constraints, and selectively adjusts a sector co-offset protection value using the approximated highest co-offset protection value as a starting point to obtain optimum PN offset assignments.

An interference analyzing system and method analyze interference in a dual mode system having a digital network overlaid on an analog network. The digital network includes portable units operating within digital cell sites; whereas, the analog network includes mobile units operating within analog cell sites. The interference analyzing system measures the amount of interference caused by and to the portable units, and the amount of interference caused by and to the digital cell sites. The system individually compares these interference amounts to a predetermined threshold. If either of the interference amounts exceeds the predetermined threshold, the system selects one of the analog cell sites for spectrum clearing and determines the amount of spectrum to be cleared from the selected analog cell site.
