    Sammanfattning : While the data traffic has increased through the years, the average revenue per user (ARPU) remains flat. Thus, mobile network operators need to find a solution for how to support the growing amounts of traffic at fixed revenue per user. LÄS MER

  4. 3. Analysis and Experimental Verification of Diameter Attacks in Long Term Evolution Networks

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Bhanu Teja Kotte; [2016]
    Nyckelord :;

    Sammanfattning : In cellular networks, the roaming interconnection was designed when there were only a few trusted parties and security was not a major concern or design criteria. Most of the roaming interconnections today are still based on the decades-old SS7 and the lack of security is being blamed for several vulnerabilities. LÄS MER

  5. 4. SCTP and Diameter Parameters for High Availability in LTE Roaming

    Master-uppsats, KTH/Radio Systems Laboratory (RS Lab)

    Nyckelord :SCTP; Diameter; IPX; LTE Roaming; Seagull; RTD; RTO; Retransmission; DEA; SCTP; Diameter; IPX; LTE roaming; Seagull; RTD; RTO; omsändning; DEA;

    Sammanfattning : Today mobile network operators utilize IP Packet exchange (IPX) carriers to interconnect their networks with other operators. Mobile network operators are free to choose one IPX carrier for their data traffic and another for their control traffic. LÄS MER

  7. 5. Performance of International roaming Location Update in 3G and 4G networks

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för kommunikationssystem
