frequency spectrum


Its goal is to reduce overall system's disturbance, raises the frequency spectrum rate, and lengthens MS battery's life. the power control divides into the upward power control and the downward power control. After MS establishes a RR connection, unceasingly report this cell and the neighbor cell measurement result to MSC. BTS surveys the upward signal , these data are saved in BSS. When the processing result indicated handover, the network basis processing result, carries on lining up to the handover candidate cell, MS decides which cell again, the process is called the handover algorithm. The handover algorithm divides into the data processing process, the cell queuing process and the cell decision process, regarding these process's algorithm in the GSM standard, has not given the rigid stipulation, has given a suggestion algorithm in the GSM standard 05.08 appendices, the localization algorithm which Ericsson Corporation uses is merely in BSC decided that the cut condition one kind of software algorithm, the BSC basis survey's information carries on to the periphery cell quite lines up, this is called“Locating”in the handover process. The Locating primary data and serves the cell by the traveling carriage to survey separately then delivers the BSC computation, MS carry on the survey to the downlink, this survey including the current cell and six neighbor cell's downward signal strength and the downward signal quality, will carry on the survey through the SACCH channel transmission for BTS, BTS carry on the up link, this survey report including upward signal strength and signal quality as well as TA value.

How to improve student's mental health

 Students' mental health has been playing an increasingly important role in our lacoste polo shirts life. Indeed, it is widely accepted that it has gained growing popularity among persons in all walks of ralph lauren polo shirts life. There is a general discussion today about the issue of disorder in brains.
  Obviously, it is necessary that effective actions should be taken to prevent problems. Authorities in universities play a critical role in the situation. To begin with, schools, such as colleges or universities, can provide chances for the young men to ease their polo shirts. What's more, some are physically strong, but psychological problems are able to bring potential threats. Teaches may have a chance to find them in advance.
