5-AT命令互動之-APN
阿新 • • 發佈：2018-12-20
APN指一種網路接入技術，是通過手機上網時必須配置的一個引數，它決定了手機通過哪種接入方式來訪問網路。
對於APN在運營商上面的具體使用過程可能要查專門的資訊。
百科對APN的使用過程有以下例項：
GPRS專網系統終端上網登入伺服器平臺的流程為： 1）使用者發出GPRS登入請求，請求中包括由運營商為GPRS專網系統專門分配的專網APN； 2）根據請求中的APN，SGSN向DNS伺服器發出查詢請求，找到與企業伺服器平臺連線的GGSN，並將使用者請求通過GTP隧道封裝送給GGSN； 3）GGSN將使用者認證資訊（包括手機號碼、使用者賬號、密碼等）通過專線送至Radius進行認證； 4）Radius認證伺服器看到手機號等認證資訊，確認是合法使用者發來的請求，向DHCP伺服器請求分配使用者地址； 5）Radius認證通過後，由Radius向GGSN傳送攜帶使用者地址的確認資訊； 6）使用者得到了IP地址，就可以攜帶資料包，對GPRS專網系統資訊查詢和業務處理平臺進行訪問。
在我們使用模組上網時，一般在查詢到IMSI之後就要設定APN了，對於APN的設定有很多AT介面可以設定，下面以移遠的和SimCom的模組進行舉例
移遠模組
1.AT+CGDCONT 定義 PDP 上下文
AT+CGDCONT=1,"IP","apn"
<cid> 1~3 數值型引數；用於指定 PDP 上下文標識。該引數對 TE-MT 介面而言是本地引數， 並且可用於其他 PDP 上下文相關命令 <PDP_type> “IP” （分組資料協議型別）字元型引數；用於指定分組資料協議的型別。僅支援”IP”， 網際網路協議 IP（Internet Protocol）（IETF STD5） <APN> 接入點名稱；表示一個字串引數，用於選擇 GGSN 或外部分組資料網路的邏輯名稱。若 該引數取值為空或省略，則需要請求籤約值 <PDP_addr> 字元型引數；用於表示對於特定 PDP 上下文，MT 分配的地址空間。若該引數取值為空或 省略，則 TE 在 PDP 啟動過程中提供其他取值；若不能提供其他取值，則需要請求動態地 址。即便在 PDP 啟動過程中已分配地址，該命令的讀出形式仍繼續返回為空。使用 AT+CGPADDR 命令，可讀出該分配地址 <d_comp> 關閉（若取值省略，則該引數為預設值）；數值型引數；用於控制 PDP 資料壓縮 <h_comp> 關閉（若取值省略，則該引數為預設值）；數值型引數；用於控制 PDP 頭
2.AT+QICSGP 設定 CSD 或 或 GPRS
AT+QICSGP=1,"apn","username","passward"
<mode> 數字引數；表明無線連線模式 0 CSD 連線 1 GPRS 連線 GPRS 連線配置的引數說明： <apn> 字串引數；表明接入點名稱 <user name> 字串引數；表明使用者名稱 <password> 字串引數；表明使用者密碼 <dial number> 字串引數；表明 CSD 號碼 <user name> 字串引數；表明 CSD 連線使用者名稱 <password> 字串引數；表明 CSD 連線使用者密碼 <rate> 數字引數；表明 CSD 連線速率 0 2400 1 4800 2 9600（預設值） 3 14400
3.AT+QIREGAPP 啟動任務並設定接入點 APN 、使用者名稱和密碼
AT+QIREGAPP="apn","username","passward"
<apn> 字串引數；表明 GPRS/CSD 接入點名稱
<user name> 字串引數；表明 GPRS/CSD 接入點使用者名稱
<password> 字串引數；表明 GPRS/CSD 接入點使用者密碼
<rate> 表明 CSD 資料傳輸速率```
SimCom模組
AT+CGDCONT 定義 PDP 上下文
AT+CGDCONT=1,"IP","apn"
<cid> 1~3 數值型引數；用於指定 PDP 上下文標識。該引數對 TE-MT 介面而言是本地引數，
並且可用於其他 PDP 上下文相關命令
<PDP_type> “IP” （分組資料協議型別）字元型引數；用於指定分組資料協議的型別。僅支援”IP”，
網際網路協議 IP（Internet Protocol）（IETF STD5）
<APN> 接入點名稱；表示一個字串引數，用於選擇 GGSN 或外部分組資料網路的邏輯名稱。若
該引數取值為空或省略，則需要請求籤約值
<PDP_addr> 字元型引數；用於表示對於特定 PDP 上下文，MT 分配的地址空間。若該引數取值為空或
省略，則 TE 在 PDP 啟動過程中提供其他取值；若不能提供其他取值，則需要請求動態地
址。即便在 PDP 啟動過程中已分配地址，該命令的讀出形式仍繼續返回為空。使用
AT+CGPADDR 命令，可讀出該分配地址
<d_comp> 關閉（若取值省略，則該引數為預設值）；數值型引數；用於控制 PDP 資料壓縮
<h_comp> 關閉（若取值省略，則該引數為預設值）；數值型引數；用於控制 PDP 頭
AT+CIPCSGP 設定 CSD 或 或 GPRS
AT+CIPCSGP=1,"apn","username","passward"
<mode> 數字引數；表明無線連線模式
0 CSD 連線
1 GPRS 連線
GPRS 連線配置的引數說明：
<apn> 字串引數；表明接入點名稱
<user name> 字串引數；表明使用者名稱
<password> 字串引數；表明使用者密碼
<dial number> 字串引數；表明 CSD 號碼
<user name> 字串引數；表明 CSD 連線使用者名稱
<password> 字串引數；表明 CSD 連線使用者密碼
<rate> 數字引數；表明 CSD 連線速率
0 2400
1 4800
2 9600（預設值）
3 14400
AT+CSTT 啟動任務並設定接入點 APN 、使用者名稱和密碼
AT+QIREGAPP="apn","username","passward"
<apn> 字串引數；表明 GPRS 接入點名稱
<user name> 字串引數；表明 GPRS 接入點使用者名稱
<password> 字串引數；表明 GPRS 接入點使用者密碼
Android系統
對於Android系統APN的設定必須要有接入點號碼MCC+MNC，接入點名稱APN，呼叫介面設定完是存在apn的資料庫裡面。
當前使用的apn，adb pull /data/data/com.android.providers.telephony/shared_prefs/preferred-apn.xml
預設的apn，adb pull /system/etc/apns-conf.xml
全部apn資料庫，adb pull /data/data/com.android.providers.telephony/databases/telephony.db
用SQLiteSpy.exe檢視db檔案 file -> open database -> carriers
在/system/etc/apns-conf.xml 中新增 對應302720 這條apn 記錄，然後push 進去， 刪除 telephony.db 這個資料庫，重啟測一下
