STUDI PERENCANAAN PUSH TO TALK PADA JARINGAN<br /> GPRS TELKOMSEL BANDUNG<br /> <br /> THE STUDY OF PUSH TO TALK PLANNING ON TELKOMSEL<br /> BANDUNG GPRS NETWORK

ABSTRAKSI: GPRS adalah suatu sistem layanan komunikasi data berbasis packet switching yang ditumpangkan pada kanal fisik radio GSM guna meningkatkan efisiensi dan menyediakan fleksibilitas layanan ke jaringan paket data eksternal. Integrasi layanan GPRS pada jaringan GSM menyebabkan perubahan arsitektur jaringan GSM berupa pengalokasian kanal radio akses untuk GPRS serta penambahan sejumlah perangkat dan antarmuka baru. Banyak layanan yang dapat dilewatkan melalui jaringan paket data ini, salah satu layanan berbasis paket data diharapkan dapat meningkatkan utilitas jaringan paket data adalah Push To Talk (PTT). PTT adalah layanan voice dengan mode Half Duplex yang dikembangkan untuk dapat diimplementasikan pada jaringan seluler. PTT merupakan layanan instan yang memungkinkan komunikasi one-to-one dan one-to-many user, serta tidak memerlukan dial-up tetapi user tinggal menekan button pada UE (User Equipment) ketika akan bicara. Akan tetapi, bila jalur komunikasi sedang padat maka percakapan yang menggunakan layanan ini akan mengalami delay. Pada Tugas Akhir ini, perencanaan dilakukan pada PT. Telkomsel regional Bandung. Proses perencanaan dimulai dengan analisis performansi jaringan GPRS yang ada dari segi trafik dan ketersediaan kanal. Kemudian dilakukan perencanaan sistem PTT yang meliputi infrastruktur sistem PTT, peramalan jumlah pengguna PTT, pendimensian perangkat, coverage area layanan PTT, dan QoS sistem PTT berdasarkan hasil perencanaan. Tugas Akhir menghasilkan perhitungan pelanggan PTT hingga 2010 yaitu 14566 pengguna. Jumlah komponen PTT yang dibutuhkan: 1 unit GSN, 1 unit Control Switch, 1 unit Active Directory, dan 2 unit Web Server. Bandwith yang dibutuhkan sebesar 27,45 kbps.Kata Kunci : -ABSTRACT: GPRS is data communication service system based on packet switching which is carried by the GSM radio fisic channel in order to increase efficiency and provide flexibility of the service to external data packet network. GPRS service integration on GSM network changes of GSM network architecture which are allocation of access radio channel to GPRS and adding of new equipment and interface. Many services could be pass through this data packet network, one of the service based on data packet which is hopefully can increase data packet network utility is Push To Talk (PTT). PTT is a half-duplex-mode voice service which is developed so that it can be implemented in the cellular network. PTT is an instant service which enables one-to-one and one-to-many user communication and doesn&rsquo;t need a dial-up process, users only have to press the button on the UE (User Equipment) when they want to start to talk. However, if the communication links is dense then the conversation which use this service will have delays. On this final assignment, the planning is done by PT Telkomsel region Bandung. The planning process is begun with existing GPRS network performance analysis which are traffic aspect and channel availability. Then continued by the planning of PTT system including PTT system infrastructure, the amount of PTT user forecast, equipment dimensioning, the coverage of PTT service area, and PTT system QoS according to the planning outcome. The outcome of this final assignment is the total of PTT subscriber on 2010 which is 14566 user. The amount of PTT cequipment needed are 1 unit of GSN, 1 unit of control switch, 1 unit of Active Directory, and 2 units of web servers.Keyword:
