NOKIA手机工程模式说明

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。

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 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). 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 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 eleven logical channels. Depending on the number of frequencies used in a cell, the number of physical channels available is eight times the number ofused frequecies. most of these physical channels have to be allocated for traffic purposes. There aremore than one ways in these aleven logical channels are mapped on the available physical channels.How they are mapped varies from cell to cell depending on a number of categories. Channelcombination tells about the mapping method used in the particular cello Paging groups. Normally in one cell there are more than one paging channels. To prevent a mobile to listening to all the paging channels for a paging message, the paging channels are divided suchthat, 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. This is necessary if, for example, theuser initiates a conversation in the current cell, and then decides to move on. The MS has measurethe 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 Power Save) 菜单10-2| NO 7 B49 || 16 x || || |B49 - 蜂窝阻塞 (参考菜单 10-19)16 - 信道号x - 发射是为- 0，待机时为-1菜单 10-3, 10-4, 10-5|16 50 -56 50| |18 19 -87 19| |29 13 -93 13| |xxx ccc vvv ccc||90 32 -74 32| |20 18 -88 18| |xx xx xx xx| |. ||17-99 -80-99| |83 15 -89 15| |xx xx xx xx| |. || N N | | N N N | | N xx xx | | AA AA AA |xxx - means BCCH carrier number of the servingcell in decimal instead of BCCH carrier number DCHcarrier number will be desplayed in activ mode.ccc - means C1 value of the neighbour instead of C1 valueletter "B" and BSIC value will be desplayed in activ mode.vvv - 表示接收功率等级（dBm）AA - 普通小区(N), 阻塞小区 (B).菜单 10-3 Number of serving cell, and 2 neigbours.菜单 10-4 Next 3 neigbours.菜单 10-5 Next 3.菜单 10-6|26002 26202||41040 26001||C9E00 xxxxx||21303 xxxxx|看过一些测试项就可看到如下显示：|26002 26202||00000 26001||11111 xxxxx||33333 xxxxx|屏幕左边是予存网络列表, Nokia 6110手机无法进行编辑，而老的Alcatel HC 1000可以编辑；262 02 - 目前注册使用中的网络代码 D2 Privat network code.260 01 - 曾经尝试登录被禁用网络代码Plus GSM networ code.Menu 10-7|E A H C I BR||1 1 0 1 0 00|| || |E: 系统是否支持紧急求救电话即112： 1为支持、0为不支持；A: attach-detach程序，1为支持，0为不支持；H: 是否支持半速率编码，1为支持，0为不支持；C: C2值广播，1为支持，0为不支持；I: 系统第7、8信息广播，1为支持，为不支持；B: 系统广播，1为支持，0为不支持；R: re-establishment.1为支持，0为不支持；Menu 10-10|TMSI 1620101B||T321 : 1 /30||PRP :6 15 90|| - 2 16|TMSI - 临时移动台识别码：Temporary Mobile Subscriber IdentityT321 - Counter (min 1, max 240, where 1 means 6 min timebetween location updates and 240 means 240*6min=24hbetween location updates).PRP - Paging Repeat Period (range is 2-9, when paging is inevery second multiframe, mobile takes more current that if it werein every 9th multiframe).16 in the last line is number of serving cell channel.菜单10-11|CC:260 NC:02|| LAC:2419 || CH : 16 || CID:5DE9 |CC - (MCC)移动国家码； Mobile Country Code (260 - Pland)NC - (MNC) 移动网络码Mobile Network Code (02 - Era GSM)LAC - 本地区域识别码 Location Area CodeCH - 使用中载频号码 Serving cell channel numberCID - 基站编号（Cell ID） Cell Identifier菜单 10-12|CIPHER :OFF ||HOPPINNG:OFF ||DTX : ON ||IMSI : ON |CIPHER - ciphering value A51, A52 or OFFHOPPING - 跳频值 Hopping value - ON/OFFDTX - Discontinuos Transmission (Mechanism)ON/OFFIMSI - International Mobile Subscriber Identity菜单10-13| NOTALLOWED | | xxxxxxxxxxxx || DTX(DEF) :ON | | yyyyyyyyyyyy || DTX(BS) :USE| | zzzzzzzzzzzz || | | |With this display is possible to change MS to use DTX or not if BS allows MS to decide it.To change DTX state, You must activate this display from MENU.

By setting the barring on in the base station normal GSM phones will not try to register these barred cells. By selecting cell barring reversed, the MS will only use the cells to be tested. However, if at the same time it is wanted that MS will be capable to use normal network cell barring ignored can be set.This test can be activated only from the MENU selecting item field test, or with shortcut menu-10-19.
