Info

answers, and the number to be blocked, the MS sends the message to the Operator automatically. The Operator forwards the message to CP then from the CP to the specified operator. The specified operator looks for the number in their database, checks the PIN number and the answers for verification and does the operation as requested, that is, blocks the SIM and sends a confirmation message to the MS via CP and the user’s operator. The technical aspects cover even into more details about the module which is as follow. Let’s say, an aktel_user lost his SIM and using a Teletalk number to BLOCK the SIM. As mentioned before the set has to have the software being installed. The user opens the software and go to the SIM Block/Unblock module, types the PIN number, answers three questions, and gives the aktel_number (to be blocked) and chooses the BLOCK option from the combo list. The MS holds the “BLOCK” in a header and as the user presses the “GO” button the MS software sends the message to the Operator at a certain port number automatically. The Teletalk Operator sees the port number and forwards the message to the CP. The CP reads the number (aktel_number) that is requested to be blocked and sends the entire message to the specified operator, in this case to Aktel Operator. The Aktel Operator verifies that whether the person, who has requested to block the SIM, is the right person to request it or not by matching the answers and the PIN numbers with their data that they have stored in their Customer Information Database (CID). The message is not to be of case sensitive. If the information does not match with their stored data, the Aktel Operator sends an error message to the user via first CP which then forwards to the Teletalk Operator. The user then gets the error message form the Teletalk Operator. However, if the information does match with their stored ones, they updates their Home Local Register (HLR) table by making the SIM deactivate and sending a confirmation message to the user. HLR is being updated in case of post-paid user, but if the user is pre-paid then Intelligence Network (IN) table is being updated. The proposed system has not made any differences between the 5
users but in the future implementation the differences between the post-paid and the pre-paid users would be taken into account. 6
