1. Introduction

For any business promotion when an operator provides mobile number database to an

OBD solution provider, almost 30 - 40 percent of the OBD calls results unsuccessful due to any of

the following status of the mobile numbers:

Busy

Idle

IMSI_detached

MobileSubscriberPurged

NoResponeFromPeer

NotProvidedFromVLR

NotRegistered

RestrictedArea

unknown_subscriber

Any Time Interrogation (ATI) server is intended to work as a centralized system to extract

and capture the mobile numbers of an operator circle that are in continuous use and are readily

available for OBD calls. These captured mobile numbers can then be considered for the OBD

promotions to achieve an optimum number of success calls.

Features and Benefits

Thoroughly filters and provides the in-use mobile numbers for OBD calling

Remarkably improves the rate of success calls

Efficiently truncates roaming subscribed numbers to reduce the OBD call charges

Checks the Mobile Number Portability status information of mobile numbers

Extracts the Location Based Information of mobile numbers to track its physical location

2. Technical Overview

This overview is intended to give a high-level introduction of key components of the ATI

server how they function individually and how they fit together.

The ATI server queries with the various components of the operator circle network to

extract mobile numbers that are in continuous use.

Mobile User:A mobile phone number to which an OBD call will be sent.

BTS: Base transceiver station that facilitates a wireless communication between the mobilephone number and the operator circle network.

VLR:Visitor Location Register is a database, part of the GSM mobile phone system, which storesinformation about all the mobiles that are currently under the jurisdiction of the MSC (MobileSwitching Center) which it serves.

HLR: Home Location Register is a database of user (subscriber) information, i.e., customerprofiles. A HLR contains user information such as account information, account status, userpreferences, features subscribed to by the user, users current location, etc. HLRs are used bythe Mobile Switching Centers (MSCs) to originate and deliver arriving mobile calls.

MSC: The mobile switching center (MSC) is the primary service delivery node for GSM/CDMA,responsible forrouting voice calls and SMS as well as other services.

ATI Server:Any Time Interrogation (ATI) is a server that queries with VLR and HLR to extractlocation information, subscriber status, current location, IMEI, MS class mark and MNP status.The ATI server then assorts only the subscriber status information to prepare the in-use mobilenumbers data and provides it for the OBD calling.

OBD Server: Out Bound Dialing server is a system that conducts business promotional calls tothe specific mobile numbers, which are uploaded in to the OBD database.

2.1. Prerequ isit es

The section details the prerequisites for ATI server at both OBD side and the operator

circle MSC side.

OBD Side:

SS7 Link with MAP enabled (License)

Signaling card (that supports MAP,SCCP,TCAP)

Server (High-end IBM/Lenovo system)

LAN connectivity and power supply

Operator MSC Side:

Originating Point Code and Destination Point Code of SS7 link

SSN - 6,7,8

Checking keyword - GT-91xxxxxxxxxx (MSISDN)

Fix the SS7 plan id as ssf-0xc(Reserved National)

Configure GSM SCF in HLR and MSC to interact with IN(Intelligent Network)

2.2. ATI Wo rk Flow

The following list elucidates the ATI server work flow:

1. Operator provides the mobile numbers database.

2. The mobile numbers database is imported into the ATI Server.

3. The ATI server sends the GT+SSN+MSISDN for every mobile number to the

MSC to check the status.

4. The MSC verifies the sent data of the mobile number with the HLR database.

5. HLR interacts with IN (Intelligent Network) to fetch data of the mobile number.

6. HLR sends the fetched data to the MSC.

7. MSC sends the status of the mobile number to the ATI server.

8. ATI server filters the mobile numbers on the basis of received information and

prepares a database of in-use mobile numbers.

9. The prepared database is then uploaded into to OBD server for promotional

calls.

2.3. ATI Add i t ional Components

This section outlines the components of ATI servers Additional Components.

GTT: GlobalTitle Translation is the SS7 equivalent to IP routing. GTT examines the

destination address (e.g. the number being called) and decides how to identify it over the

telephone network. This process can include global title analysis, which is the act of looking up

the number and finding a result address, and global title modification. Also, it is possible to route

GTT result on SSN. Implies, instead of the GTT routing, lower level MTP routing will be used to

route the message. Equivalently, in a system that is using SS7 over IP (for example, SIGTRAN),

the result from GTT may route to an IP server, though the exact details depend greatly on the

variant ofSS7 that is being used over IP.

SSN:Signaling Connection Control Part (SCCP) subsystem numbers are used to identify

applications within network entities that use SCCP signaling. In Global System for Mobile

Communications (GSM) and Universal Mobile Telecommunications System (UMTS), subsystem

numbers may be used between Public Land Mobile Networks (PLMNs), that are taken from the

globally standardized range (1 - 31) or the part of the national network range (129 - 150) reserved

for GSM/UMTS use between PLMNs. For use within a PLMN, numbers are taken from the part of

the national network range (32 - 128 & 151 - 254) not reserved for GSM/UMTS use between

PLMNs.

The following are the globally standardized subsystem numbers that are allocated for

use, by GSM/UMTS:
