诺基亚手机工程模式说明

1、NOKIA手机工程模式的说明书简介： NOKIA移动电话的工程模式名称为“Net monitor"分组画面为改锥、铁锤和手机，诺基亚的工程模式启动后可以通过命令开启或关闭。前面的画面显示系统网络的功能，后面则以介绍手机内软硬件资料为主。· 载频号码、在GSM系统的范围是1-124； · Carrier number. The range in GSM is 1-124 · 移动台接收电平（dBM值）； · MS RX level in dBM · 接收信号等级，在GSM系统的范围是0-7； · Received signal

8、AGCH->SDCC->BCCH->CCCH · AGCH - Access Grant Channel - is the answer to RACH. It's used to assign a mobile a Stand-alone Dedicated Control Channel (SDCCH). It's downlink and point to point channel. · SDCC - (SDCCH) Stand-alone Dedicated Control Channel - It's used for

9、system sygnalling: cell set-up, authentication, location update, assigment to traffic channels and transmission of short messages · TFR - (TCH) Traffic Channels - Physical channels also transfer user data, which can be either in the form of Half Rate traffic (6.5kbit/s) or Full Rate (13kbit/s).

10、 Another form of traffic channel is the Enhanced Full Rate (EFR) Traffich Channel. The speech coding in EFR is still dona at 13kbit/s, but the coding mechanism is different than that used for normal full rate traffic. EFR coding gives better speech quality than normal full rate. Traffic channels can

11、 transmit both speech and data. these are bi-directional channels. · BCCH - Broadcast Control Channel contains detailed network and cell specific information such as: · o Frequencies used in the particular cell. o Frequency hopping sequence. o Channel Combination. In the GSM there are elev

12、en logical channels. Depending on the number of frequencies used in a cell, the number of physical channels available is eight times the number of used frequecies. most of these physical channels have to be allocated for traffic purposes. There are more than one ways in these aleven logical channels

13、 are mapped on the available physical channels. How they are mapped varies from cell to cell depending on a number of categories. Channel combination tells about the mapping method used in the particular cell o Paging groups. Normally in one cell there are more than one paging channels. To prevent a

14、 mobile to listening to all the paging channels for a paging message, the paging channels are divided such that, a group of mobile stations listen to a particular paging channel only. o Information on surrounding cells. A mobile station has to know what are the cells surrounding the present cell and

15、 what frequencies are being broadcast on them. This is necessary if, for example, the user initiates a conversation in the current cell, and then decides to move on. The MS has measure the signal strength and quality of the surrounding cells and report to the base station controller. · SEARCH M
