Intelligent Network (IN)

By engineer, on October 23rd, 2009

Intelligent Network (IN) is playing the key roll on the telecommunication infrastructures. The main function of Intelligent Network (IN) is to charge any transaction made by prepaid subscribers while accessing the telecommunication service such as mobile internet service. The key point is charging to the prepaid subscribers. Meanwhile postpaid subscriber will be done by another network element. This network element could be mediation server which collects the Code Detail Record (CDR) from another telecommunication infrastructure that generates the CDR.  Intelligent Network (IN) is responsible to deduct subscriber’s balance while they retrieved the service they already requested such as mobile internet service . Any telecommunication infrastructures which  give a charging to the subscribers should connect to the Intelligent Network (IN) with many kind protocols then deduct the subscriber’s balance while they are succeed to access it. The protocol could be http, telnet, SMPP, SMPP plus etc

For example subscriber makes a session through their laptop/computer to access wireless or mobile internet service. What will happen on the back end system during balance deduction are;

  1. Charging system of wireless or mobile internet service will identify the subscribers profile on its database
  2. Charging system of wireless or mobile internet service will query the subscriber status to the Intelligent Network
  3. Charging system of wireless or mobile internet service will reserve mount of balance to access the traffic for some times
  4. Intelligent Network (IN) will deduct the balance as much as requested by charging system of wireless or mobile internet service
  5. Charging system of wireless or mobile internet service will request again mount of balance while the first request is used by subscriber
  6. Intelligent Network (IN) will do the same until subscriber disconnect the session or has insufficient balance

Intelligent Network (IN) consist of several network element which responsible to different functions. They are:

  1. Service Management Protocol (SMP
  2. Service Control Protocol (SCP
  3. Data Access Control Point (DACP)

Usually some telecommunication infrastructures which require connecting to Intelligent Network (IN) to deduct subscriber’s balance will not connect directly to SCP but they are using Intelligent Network (IN) gateway. As we know that telecommunication companies have many kinds of telecommunication services which handled by many telecommunication infrastructures to run the services. Each service usually will be handled by particular network elements. It means, there will be a lot of connection to Intelligent Network. Intelligent Network (IN) gateway is avoiding undesired Intelligent Network (IN) performance such high utilization
