  1. 11. Emulation of IP Core Network for Testing of the Serving GRPS Support Node (SGSN) Routing Application

    Magister-uppsats, Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Författare :Hossein Torkaman; [2009]
    Nyckelord :GPRS; SGSN; Simulation of IP Core Network; Service GPRS Support Node; Routing Application; 3G; OSPF; RIP; BGP;

    Sammanfattning : This thesis aims to investigate a method and tool for emulation of the General Packet Radio Service (GPRS) core network needed as an environment to test the routing functionality. GPRS is the most widely adopted mobile packet data delivery technology in the world. LÄS MER

  3. 12. Principles for Channel Allocation in GSM

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

    Författare :Jonas Månsson; [2008]
    Nyckelord :GSM GPRS EDGE Channel Allocation TDMA time slot;

    Sammanfattning : In today's GSM system there is a complex resource situation when it comes to the scarce TDMA channels in the air interface, the time slots. There are both voice call services that use one or a half time slot and there are packet data users, that may share time slots with other packet data users, and they can use multiple channels at the same time.

  4. 13. Radio Netwok Test Configuration for Maximum Test Coverage : Model based load generation in system verification of a GSM Base Station Controller

    Master-uppsats, Kommunikationssystem; Tekniska högskolan

    Författare :Staffan Grundberg; [2008]
    Nyckelord :GSM; BSC; Verification; Radio Network; Radio Propagation;

    Sammanfattning : GSM has been developed during more than a decade and has grown to a very complex system. Due to the wide range of functionality, the high capacity and the complexity of the BSC the testing of stability and performance is time consuming. LÄS MER

  5. 14. Determining the feasibility of automatically translating SMILE to a Java framework

    Master-uppsats, Institutionen för datavetenskap

    Författare :Said Aspen; [2008]
    Nyckelord :State-machines; software translation; Java; software conversion; MTsim; TSS Language; state matrix programming; Java framework; framework design; object oriented implementation of state machines; abstract syntax tree;

    Sammanfattning : MTsim (Mobile Traffic Simulator) is an Ericsson AB internal software application that is part of 2Gsim. It is used to simulate elements of a GSM (Global System for Mobile communications) network for feature testing and automated testing. LÄS MER

  7. 15. Investigation of Automated Terminal Interoperability Test

    Uppsats för yrkesexamina på grundnivå, Institutionen för datavetenskap

    Författare :Niklas Brammer; [2008]
    Nyckelord :GSM; UMTS; LTE; Interoperability Test; Test Automation;

    Sammanfattning : In order to develop and secure the functionality of its cellular communications systems, Ericsson deals with numerous R&D and I&V activities. One important aspect is interoperability with mobile terminals from different vendors on the world market. Therefore Ericsson co-operates with mobile platform and user equipment manufacturers. LÄS MER
