at是属于什么工作_工作说明书是工作分析的_at least是什么意思啊

AT+COPS;PLMN selection

AT+CGREGGPRS network registration status

AT+CPBRRead phonebook entries

从search network.7z中的log看at是属于什么工作,RIL和MUX应该工作正常。

[ 02-20 21:29:19.990 1132:0x4a0 D/AT ] AT[2]> (RIL-> modem): AT+COPS=?

Record Number 1929

如果电脑中同时存在多个网络连接,如“本地连接”、“无线网络连接”、cmcc连接等,而与宽带modem相连的网络连接被禁用at是属于什么工作,进行宽带拨号时,也会提示错误678。030期:30-02=28 030期红球绝杀28 对。接下来就是关于modem的服务,如:ccci_fsd、ccci_mdinit、pppd_gprs、pppd、gsm0710muxd、muxtestapp、sockcli、socksrv、muxreport、ril-daemon等,除了前面2个,后面的都带有disabled的参数,需要按名启动。

绿色的消息应该在红色之前发送

按照协议25.304:

The UE shall use one of the following two search procedures:

a) Initial CellSelection

This procedure requires no prior knowledge of which RF channels areUTRA carriers. The UE shall scan all RF channels in the UTRA bandsaccording to its capabilities to find a suitable cell. On eachcarrier, the UE need only search for the strongest cell. Once asuitable cell is found this cell shall be selected.

b) Stored Information CellSelection

This procedure requires stored information of carrier frequenciesand optionally also information on cell parameters, e.g. scramblingcodes, from previously received measurement control informationelements. Once the UE has found a suitable cell the UE shall selectit. If no suitable cell is found the Initial cell selectionprocedure shall be started

按照协议,关机后forbiden LAI会被erase掉。

The Mobile Equipment shall contain a list of "forbidden locationareas for roaming", as well as a list of "forbidden location areasfor regional provision of service". These lists shall be erasedwhen the MS is switched off or when the SIM/USIM is removed, andperiodically (with period in the range 12 to 24 hours).

别的商用终端每次开机会首先搜索上次成功驻留的小区(频点加cpi),而我们的终端没有这个功能,把搜网的所有希望寄托在RSSI的测量上。

如果增加了每次开机首先搜索上次驻留成功的小区,这个问题应该会好。

ATD11800020344;注意:语音电话是有

ATH挂断电话

ATA接电话

at least是什么意思啊_at是属于什么工作_工作说明书是工作分析的

AT+CBST=134,1,0 设置视频电话格式

ATD11800020340注意:视频电话最后没有分好“;”

AT+CSCA="+8613900210021" 设置短消息中心号码

AT+CSMP=17,167,0,0设置短消息参数

AT+CMGS="11800020330"发送短消息

at+cgdcont=1,"IP","zte.com"拨打ps,以及APN

AT+CGEQREQ=1,2,64,64;设置ps上下行速率

at+cgact=1,1激活ps

Android重启之后,PS链路就建立不起来了(见)。从PPPD的LOG的来看,必然是如下打印:02-2910:06:29.908 2770 2770 D pppd : using channel 4

工作说明书是工作分析的_at是属于什么工作_at least是什么意思啊

02-29 10:06:29.978 2770 2770 I pppd : Using interface ppp0

重启的流程:

03-02 03:20:07.009 1128 1128 I DEBUG : pid: 1292, tid: 1303>>> com.android.phone<<<进程挂掉

导致相关的服务die

03-02 03:20:09.399 1125 1125 I ServiceManager: service 'isms'died

03-02 03:20:09.399 1125 1125 I ServiceManager: service'simphonebook' died

03-02 03:20:09.399 1125 1125 I ServiceManager: service'iphonesubinfo' died

然后导致zygote进程挂掉,接着就重启了。

03-02 03:20:10.699 1128 1128 I DEBUG : pid: 1134, tid: 1134>>> zygote<<<
