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 quality. The range in GSM is 0-7 移动台发射功率等级,在GS
2、M系统的范围是5-15级; MS TX power level. The range in GSM is 5-15 C1(多径衰耗标准); C1 (path loss criterion, used for cell selection and reselection, the range in GSM is -99.99) RLT(音频超时); RLT (Radio Link Timeout) 时隙(时槽?),在GSM系统的范围是0-7; Timeslot. The range in GSM is 0-7 发射转态指示; Indication of the transmitter statu

7、话-CCCH 开机时CHT项变化:AGCH-SDCC-BCCH-CCCH AGCH - Access Grant Channel - is the answer to RACH. Its used to assign a mobile a Stand-alone Dedicated Control Channel (SDCCH). Its downlink and point to point channel. SDCC - (SDCCH) Stand-alone Dedicated Control Channel - Its used for system sygnalling: cell
8、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). Another form of traffic channe
9、l 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 transmit both speech and data.
10、 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 eleven logical channels. Depending on the number
11、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 are mapped on the available physical channel
12、s. 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 mobile to listening to all the paging channe
13、ls 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 what frequencies are being broadcast on them
14、. 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 Mobile Station is searching for signal. NSPS (No Serv
