GENERAL PACKET RADIO SERVICE (GPRS)

Chapter 24

   The demand for communication is now increase, and need innovation process in order to produce a fast and reliable communication industry. If these things happen, the services will be more efficient and more effective especially to those subscribers who are engage in business. The GSM help the growing of data traffic in general all point to a significant business opportunity for GSM operators. That’s why subscribers of this system increase. But as always, users need changes and improvement of what they are using. They want a high speed and broader band communication so that they can make their task easier and faster.

     Now a new communication system is made in order to improve the needs of the users. This device is the General Packet Radio Service or (GPRS) it is the key milestone for GSM data. The price of this is chipper that the end users can really afford to subscribe. Before the people decide to choose communication technique, they first consider the price then the durability and reliability of the product is their second basis.

     GPRS also extends the packet data capabilities of the GSM network from packet data on signaling channel service. GPRS is also fit in with the existing GSM PLMN as well as the packet data networks. PLMN provides wireless access to wired packet data network. GPRS use for short message services or SMS components to provide SMS over GPRS. It will provide a seamless network infrastructure for operation and maintenance of the network. GPRS gives mobile users faster data speed and particularly good internet traffic. It will enable voice and data calls to be handled simultaneously. Users can have 342 always on connectivity to the mobile internet enjoying high speed delivery of e-mails with large file attachments, web surfing, and access to corporate Local Area Network.

    

      GPRS was also defined as a provider for true packet radio service on GSM networks by the European Telecommunication Standards Institute. GPRS was developed to enable GSM operators to meet the growing demands for wireless packet data service that is a result of the explosive growth of the internet and corporate intranets. Application of this network require relatively high throughput and are characterize by bursty traffic patterns and asymmetrical throughput needs. Example of these is web browsing, it is a result of burst of network traffic while information is being transmitted or received followed by long idle periods while the data is being sent from the client device than is being sent from the client device to the server.

      GPRS roaming use for calls and SMS messages, the growth of using this is very fast because many countries adopted this technique in order to support those who are communicating in one country to another. This roaming is considered as a multibillion business according to those who are engage in this business. The GPRS PLMN enables mobile users to roam within a geographic coverage area and receive continuous wireless packet data services. The user will move while actively sending and receiving data or may move during periods of inactivity. Either way the network tracks the location of the MS so that incoming packets can be routed to MS when they arrived. The GPRS PLMN interfaces with the MS via the air interface. It will initially provided using an enhanced version of standards GSM interface. The operators will now evolve their network to incorporate more advanced radio interfaces in the future so that they can deliver higher data rates to the end users. The GPRS PLMN interfaces as an overlay to traditional public packet data network using standards Packet Data Protocol (PDS).
