Pseudo-pilot Application Of Technology In The Hard Handoff In The Cdma Network

In recent years, along with our country science and technology, economy and so on many professions swift and violent development, the communications system can the more and more widespread application Develops from the basic pronunciation service to the present each kind of data increment service, the user more and more is also high to the correspondence quality and the service demand, Facing the mobile communication service unceasing development and the service unceasing promotion, the China Unicom CDMA network is facing a series of new challenges. As a result of the CDMA mobile subscriber's rapid growth, some big local high traffic loads also along with it growth, merely depend on the single carrier frequency the capacity already user's need which cannot satisfy grows day by day, appears the telephone traffic overflow frequently the question. In order to solve this problem, the urban district high traffic load region base depot uses the multi- carrier frequencies service pattern to become inevitably. Along with the multi- carrier frequencies base depot widespread application, in a quite long time, our country CDMA network forms the multi- carrier frequencies and the single carrier frequency coexistence condition, between different carrier frequency hard cut on along with it increase, thus causes the failure rate the increase.This article designs is for solve but causes the telephone conversation failure rate as a result of the different frequency cut to launch, the goal is for the enhancement different carrier frequency between cut success ratio. This design through the concrete example, in view of has the different frequency cut the base depot to carry on the false pilot frequency equipment to carry on the installment test, obtains the actual test material, then through to tests the material and the test environment analysis, the computation, obtains uses this technology to be truly practical and feasible, the economy effective solution, realizes the CDMA network efficiency optimization.This design earlier period, I organize the project member in view of the false pilot frequency this technology plan implementation possibility, revolved the false pilot frequency several uses way the connection quality question which cut to the multi-carrier frequencies plot and the neighboring single carrier frequency plot different...
