| Abstract | ||
| Mobile cellular communication becomes more and more important in today's communication. In cellular network, the radio and fixed links required are not permanently allocated for the duration of a call .The function of the handover is to make an on going call to different cell or channel. Also it maintains a call in progress across cell boundaries in mobile communication. ESTI (European Telecommunications standards Institute) adopted Wideband code division multiple access as the mainstream air interface solution for the third-generation networks to provide a multitude of services, especially multimedia and high –bit-rate packet data. In this paper the soft/softer handover and hard handover for voice and packet data in WCDMA systems are presented. Hard handover is necessary in WCDMA and will be presented in this paper. Softer handover is implemented within one base station between different sectors; it doesn't cause the system load increase as implemented with in the base station. The implementation of soft handover can increase the coverage, capacity performance or balance the network load. Important parameters such as, adding threshold, dropping threshold and timer-to-dropping will be analyzed | ||
