AT command set for User Equipment (UE) |
Standardized basic commands are found only in ITU‑T Recommendation V.250 [14]. GSM/UMTS commands use syntax rules of extended commands. Every extended command has a test command (trailing =?) to test the existence of the command and to give information about the type of its subparameters. Parameter type commands also have a read command (trailing ?) to check the current values of subparameters. Action type commands do not store the values of any of their possible subparameters, and therefore do not have a read command.
附着的作用是在路由区注册，注册不成功有以下几种情况；
1）:NO SUITABLE LA OR LA NOT ALLOWED
2):PLMN NOT ALLOWED
3):ROMING NOT ALLOWED
附着成功后就不用再附着
开机后需要做的工作有
搜索PLMN
搜索可以住留的小区
确定网络的操作模式（GPRS附着，IMSI附着，联合附着）
在用户进行数据业务的注册时，根据用户对业务的不同要求，可以使用不同的QoS 以及
相应的PDP 上下文，以及APN 等等。HLR 的信息在通信过程中通过和SGSN 以及GGSN 的
信息交互进行信息的更新
