Telecommunication Network Designing and Planning for Interfaces for GSM.

Abstract

Telecommunications sector is growing at a fast rate. The dependence of people on the telecommunications has also increased very much. For building reliable telecommunication systems a lot of engineering and designing is required. An optimized system can only be designed after proper planning and consideration of each and every factor that can affect working of the system. This thesis is divided in two parts. A first part deals with planning of a fixed network. It involves design and engineering of telecommunication network using EWSD switches. These switches are configured and dimensioned according to the requirements of the network. History with structure and advantages of EWSD switch and various parts used in the exchange are also explained in the first part. Basic rules of designing the exchange are also discussed in this part. Practical applications are considered designing an exchange for Thapar institute of engg.and technology and second example for Patiala city. These switches comprises of three regions with their respective RSUs connected to the main exchange. Capacity of RSUs depends upon locality. We designed software that will calculate all the parameter of exchange by simply entering the capacity. Different graphs shows distribution of different parameter. Second part of thesis is related to the planning of interfaces for GSM mobile network. The core of any GSM network is its switching subsystem. The network consists of two MSCs connected to each other as well as to their respective network elements. Interfaces of GSM system are also considered in this part. Planning of core network interfaces for given traffic model is done by taking the capacity of 600K subscribers and 10000 subscribers. Designing of software is done that will calculate the no. of interfaces by entering no. of subscriber.
