CPHS介绍

CPHS(Command   PCN   Handset   Specification),   发源于英国，在欧洲和北美相对成熟.  
  通过卡内嵌入预激活命令以增强核心业务，主要业务有:  
  Operator   Name   String(6F14)；  
  Voice   mail   waiting   indication(6F11)；

注释说明如下：

• CPHS中的P（PCN）解释：GSM目前有3种不同的频率范围，分别是：
  GSM 900（又称为GSM）
  以900MHz频率范围运作，为欧洲及国际间最常见的系统。
  GSM 1800 （又称为PCN及DCS1800）
  以1800MHz频率范围运作，采用的国家包括法国、德国、英国、俄罗斯等国。
  GSM1900 （又称为PCS、PCS1900及DCS1900）
  美国和加拿大使用1900MHz此频率。
• Alternate Line Service (ALS)：你可以同时和几个人通话，并在两线之间进行切换。
• CSP ：The Customer Service Profile (CSP) is a list on the SIM which indicates the services which are customer accessible using the single command interface. Each of these services has a related bit within the CSP. Each of these CSP bits allows the ME to present only the menu item(s) relevant to that service to the user.         An entry in the Customer Service Profile consists of two bytes. The first byte is a Service Group Code which is used to associate related services together within the CSP.  Each bit of the second byte has specific significance. A bit set to '1' indicates that the service is customer accessible via the single command interface, a bit set to '0' indicates that it is not.Unused bits are set to '0'
