1. INTRODUCTION
1.1 OVERVIEW OF THE SYSTEM
The next-generation mobile network will be an integrated global system that provides heterogeneous services across network providers, network backbones, and geographical regions. Global roaming is a basic service of the future mobile networks, where terminal mobility, personal mobility, and service provider portability must be supported. A non geographic personal telecommunication number (PTN) for each mobile user is desirable to implement these types of mobile freedom. With location-independent PTNs, users can access their personalized services regardless of terminal or attachment point to the network; they can move into different service provider’s network and continue to receive subscribed services without changing their PTNs. Another advantage of the flat PTN scheme is that it is much more efficient in terms of capacity than the location-dependent numbering scheme where the capacity of the subscriber number (SN) may be exhausted in a highly populated area, whereas the SN’s capacity is wasted in a sparsely populated area. However, using the location-independent numbering plan may introduce large centralized databases into a mobile system. To make things worse, each call may require an interrogation to the centralized databases, thus signaling traffic will grow considerably and call setup time may increase dramatically.
2. DESCRIPTION OF THE PROBLEM
2.1 EXISTING SYSTEM:
The previous mobile network was use different server and each has decentralized databases. A local server is stored only its area user’s information, but not stored the other area user’s information. For example Chennai mobile user call to the Srilanka user means, First it search in the local mobile user and after finished search in India and then find it in the Srilanka server. It takes more time to find the user location because of decentralized databases. The communication traffic also occur when search client side.
2.2 PROPOSED SYSTEM:
In proposed system, the mobile network search only in server but not in client mobile. Because all user’s information maintained in centralized database server. It is avoid the communication traffic, because this is only search in server part and easily find the user.
