The Flexibility of Value Added Service can adopt any kind of established service to be one of the features of Value Added Service (VAS) contents. For example is integrating the most popular social network right now, facebook, as part of Value Added Service (VAS) features. Usually, Value Added Service (VAS) through mobile internet service has local network features which mean that all available features are coming from dedicated local servers. In the CDMA platform, one of the valuable VAS service through mobile internet service is download content service based on BREW platform. In this case, BREW server is dedicated local server then BREW client (mobile phones) can access the service directly with no need to go to internet.
By integrating facebook as the part of Value Added Service (VAS) through mobile internet service, it means the mobile phone should be allowed to access to two paths of traffic;
- Application service (download content or subscription services) to local network located on the dedicated server
- Internet service but to the certainty address, that is facebook address
Since BREW client has static menus on the mobile phone where subscribers just push to the available menu and will redirect to the particular service (application service or facebook address) then, need to be designed backend system in order to meet such requirement. Some requirement need to be considered while deploying VAS service through mobile internet service which integrated with facebook feature on mobile phone is;
1. The account injected on the BREW client should be able to access application service and facebook address.
As mentioned above that there are two paths of traffic, it is critical to design routing policy on the network infrastructures that involved to this service2
2. Internet bandwidth capacity
As we know that facebook fever is happening right now and providing a cheap mobile phone embedded BREW platform with facebook feature will make people keep “on line” longer. It means that million people make a session at the same time and longer. as the result the internet bandwidth capacity will increase very significant
3. Radio Frequency (RF) capacity issue
More people will occupy the RF capacity at the same time and for long time. Resource availability is very critical to make sure that each session from subscriber will be served by network otherwise a lot of complaint will come due to subscribers are getting network busy while accessing the service
4. Security policy
It is very important to make sure that all service available on the mobile phone is controlled and no chance to the intruder to access internal network through mobile internet service to make a change the configuration and flood it with the huge unused traffic. In this scenario, Telecommunication Company should make sure that even subscriber will be allowed to BREW server located at internal network and allowed to browse to facebook address but nothing they can do except accessing to the authorized services
