Precautions:

1. The WAP 2 Gateway of CT can only access the HTTP protocol, but the port can be arbitrary, such as access to Http://m.baidu.com, http://crj.fjgat.gov.cn:9080/

(Updated September 15, 2011)

But not accessible://m.baidu.com:80;deviceside=true; CONNECTIONUID=WAP2, the error is as follows

The telecommunication gateway complains as follows (you can get the text returned by the Telecommunication gateway in the BlackBerry Java program):

 

 
2. Licensed Telecom BlackBerry, there is no service BlackBerry Uim Card, need to modify the phone inside the engineering mode parameters, SIP user from cbtt@mycdma.cn modified to ctwap@mycdma.cn.

This time mobile phone walk Ctwap channel (but not necessarily take WAP Proxy ... ), you can connect to most of the extranet ports directly.

This may be the legendary telecommunications through the Ctwap channel of the argument bar.

2. The BIS connection can access any port



3. The BES connection depends on the IP and port that the enterprise firewall allowed to access. Some foreign companies are very strict management, BES network can only access certain IP and port. For example, do not allow access to Facebook and Sina Weibo, do not allow access to 80 of ports and so on.



4. Telecommunications licensed BlackBerry 9630/9650 opened BlackBerry Service, the default walk CTBB APN, can not walk ctnet, can only walk BES (through the Intranet)/bis/wap 23 channels.


5. The last reference code for a network connection:


      String LCase = Url.tolowercase ();  String [] connectiontypes = {"BES", "directtcp", "WAP2", "WiFi", "Cmnet", "Cmwap", "3gnet", "3gwap", "ctnet", "BIS", "NO
        
        Parameter "};
        if (typesfield.getselectedindex () = = 0) url = url + ";d eviceside=false";
        if (typesfield.getselectedindex () = = 1) url = url + ";d eviceside=true"; if (typesfield.getselectedindex () = = 2) url = url + ";d eviceside=true;
        CONNECTIONUID=WAP2 Trans ";
        if (typesfield.getselectedindex () = = 3) url = url + "; Interface=wifi";
        if (typesfield.getselectedindex () = = 4) url = url + ";d eviceside=true;apn=cmnet"; if (typesfield.getselectedindex () = = 5) url = url + ";d eviceside=true; wapgatewayip=10.0.0.172;
        Wapgatewayapn=cmwap ";
        if (typesfield.getselectedindex () = = 6) url = url + ";d eviceside=true;apn=3gnet"; if (typesfield.getselectedindex () = = 7) url = uRL + ";d eviceside=true; wapgatewayip=10.0.0.172;
        Wapgatewayapn=3gwap ";
        if (typesfield.getselectedindex () = = 8) url = url + ";d eviceside=true;apn=ctnet"; if (typesfield.getselectedindex () = = 9) url = url + ";d eviceside=false;
        Connectiontype=mds-public "; if (typesfield.getselectedindex () = =) url = URL;
