Performance Evaluation of WCDMA-to-CDMA2000 Handover Using Inter-RAT Handover Simulator

چکیده
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 and conditions for the inter-RAT handover. For the purpose of performance analysis, we build an inter-RAT handover performance simulator using OPNET. Using the simulator, we determine proper handover conditions and parameter ranges for the inter-RAT handover. Through simulation results, we assess the handover failure rate and the border cell utilization for WCDMA systems respectively.

Handover in IS-95, cdma2000, 1X-EV and WCDMA
This chapter introduces the concept of handover in IS-95-based CDMA systems and WCDMA. The necessary procedures behind pilot set maintenance are examined, and the extensions of these concepts to WCDMA, cdma2000 and 1X-EV systems are also explored. Moreover, the concept of cell site selection in 1X-EV systems is described, along with its impacts to set maintenance.

Background: In the health centers, clinical data is regularly transferred between health care personnel. The most widespread of these handoffs are the inter-shift nursing reports, which occur several times in a day and could facilitate patient care plan, patient safety and continuity of care. But previous studies and clinical experience have indicated that there is no program for this major pur...

متن کاملAdaptive channel equalization in WCDMA downlink in soft handover
Receivers based on channel equalization have proven to be one of the most promising candidates for terminal receivers in wideband code-division multiple-access (WCDMA) downlink. The channel equalizers provide multiple access interference (MAI) suppression, and thus ensure adequate receiver performance even with a high number of active users. However, the suitability of the equalizers to soft ha...
