WCDMA Handover Optimization Guidelines
نویسندگان
چکیده
This article tries to give some guidelines to optimize the 3G-2G and 3G-3G handovers, from the extracted experience of a real network in development. The purpose of the adjustment of the 3G-2G handover parameters is to offer the users with dual terminals a quality, equal or better than those ones with only 2G terminals, where in general, the 3G coverage is minor that the 2G one. On the other hand, having the 3G cells coverage area well adjusted implies a substantial increase of their quality and capacity. Key-Words: Handover, InterRat, Overlap, Coverage, Threshold, Detected

Optimization of Pilot Power for Service Coverage and Smooth Handover in WCDMA Networks
In WCDMA networks, the presence of a cell is announced through a common pilot channel (CPICH). The power levels of the pilot channels have a great impact on coverage and service quality. Using mathematical optimization techniques, we address the problem of minimizing the amount of pilot power for providing service coverage and smooth handover. We present numerical results for several realistic ...
متن کاملPerformance Evaluation of WCDMA-to-CDMA2000 Handover Using Inter-RAT Handover Simulator
To solve the problem of CDMA2000 capacity, cellular service providers in Korea have started WCDMA commercial service since 2004. The initial deployment has been done in highlycrowded city center similar to islands of coverage. Therefore, inter-RAT handover from WCDMA to CDMA2000 should be developed to provide seamless service throughout the whole country. We develop several handover procedures ...
متن کاملDownlink radio resource optimization in wide-band CDMA systems
Soft handover is analysed and optimized in the downlink direction of a WCDMA system in this paper. Downlink is chosen because the asymmetric nature of most new services supported by the next generation of mobile networks requires more capacity in that direction, and so this is likely to be the limiting factor. The study also sets out to resolve the often controversial opinions about the system ...
متن کاملOptimization of Power Control during Soft Handover in WCDMA Cellular Networks
In this paper, a new power control scheme is proposed for optimizing the power division between the BSs in the active set during soft handover. In stead of splitting the power equally between the BSs in the active set, it controls the power division according to the propagation attenuation of each radio channel. The optimized power control minimizes the interference and maintains getting benefi...
متن کاملOptimized downlink transmit power control during soft handover in WCDMA systems
This paper proposes a new power control strategy during soft handover in WCDMA systems. According to the link qualities of the downlink channels involved in soft handover, the transmit powers of the base stations in the active set are dynamically allocated. This new optimized power control scheme reduces the additional interference caused by the multiple site transmission during soft handover. ...
