Blackberry Internet Access Solution

Blackberry Internet access has always been a big problem in mainland China. Many of my friends have asked me this question. I will describe it in detail here today.

Problem:

Blackberry cannot access the Internet, or I can access the Internet on machine A, but not on machine B?

Analysis

To solve this problem, we must understand the principle of Blackberry surfing the Internet.

First, we will introduce the Internet access problems of other devices. Most mobile phones can directly use cmwap or cmnet (take China Mobile as an example) by activating the internet ). they can access the Internet easily. Even if they encounter problems, they only need to set the access method, network endpoint, and gateway.

Unlike Blackberry, Blackberry cannot directly access the internet. If you want to access the Internet, you need the cooperation of MDS, and MDS is generally used with BES. Since it involves BES, we have to mention that if there is MDS, you cannot guarantee that you will be able to access the Internet, which is related to the BES settings. The knowledge about MDS and BES is not explained much here. After all, it is quite complicated. Therefore, you need MDS to access Blackberry. So how does Blackberry use the MDS service ?, This is the Service Book to be discussed. The Service Book includes services customized by Blackberry, such as Internet access, OTA, and contacts synchronization. If the Service Book does not have a customized online Service, you still cannot access the Internet.

After discussing the MDS, let's take a look at the usage in China. Due to copyright issues and the size of the company, there are not many such machines currently using MDS, but there are many Blackberry machines in the public. How do they get online with these machines? Generally, a private MDS server is used, which is also widely seen. These issues are worth noting.

Solution

Through the above analysis, the solution is available.

Follow these steps:

1. Check whether there is a service book
2. Check whether the service book has an Internet service
3. Check whether the MDS is enabled. You may need to restart the machine.
4. If all the above are OK, check the firewall settings.

If the problem persists, it may be caused by the following reasons:

1. Whether to subscribe to data services of mobile carriers
2. Can your machine access the Internet?
3. Check the MDS (BES) server. As to why, the above analysis has mentioned.

For developers, if the program to be written cannot access the Internet, they can first check the following content in the previous step:
