GPRS

Overview

GPRS (General Packet Radio Service) is a wireless data communication service which utilizes GSM and CDMA technology system.

GPRS is a perfect solution for connecting head office to branch office through reliable transmission facility. GPRS network is suitable for data communication applications less than 32 Kbps from head office to branch office such as ATM, Payment Point, credit card authorization, Point-of-Sales (PoS), Text Message (SMS) and others.

Specifications

GPRS system is an enhancement from GSM and CDMA system for data transmission based on Internet protocol (IP). The data transfer for GSM can reach 9.6 Kbps (kilo bytes per second) while for CDMA is ranging from 55 to 155 Kbps.

METHOD OF ACCESS
Based on IP Static and GRE/IP Sec Tunneling

  • Format :
    • Dial Number : APN
    • Block IP Static : given one IP Static for each terminal
    • GRE Tunneling : one GRE Tunneling for each ATM Terminal network
  • Register Number :
    • Registered on HLR (Block Number)

ENCRYPTION / SECURITY

  • Using GRE/IP Sec Tunneling
  • Special APN provided for client
  • VPN/APN can only be accessed by registered client
  • IP Static authentication process established on HLR
  • Can be accessed by registered number only
  • IP Sec : End-to-end Security, Encryption : 3DES, Authentication : MD5
