  1. 1. Design and Implementation of an Efficient Intrusion Response System for 5G RAN Baseband Units

    Master-uppsats, Linköpings universitet/Databas och informationsteknik

    Författare :Mirna Ghazzawi; Adil Imran; [2023]
    Nyckelord :Intrusion Response System; Security; OSSEC; Radio Access Network; Baseband Units;

    Sammanfattning : The 5G Radio Access Network (RAN) is a critical system that must be secured against potential attacks, particularly its Base-Band Unit (BBU), which is a common target for intrusions. Ericsson, which is a big provider of such systems, has placed significant emphasis on implementing Intrusion Detection Systems (IDS) to detect threats. LÄS MER

  3. 2. Informal Knowledge Sharing : Grasping the Complexity of Sharing Knowledge in Ericsson’s Software Development

    Master-uppsats, Linköpings universitet/Projekt, innovationer och entreprenörskap

    Författare :Arvid Wittwång; Amanda Perlind; [2023]
    Nyckelord :Knowledge; Knowledge Management; Knowledge Sharing; Informal Knowledge Sharing; Knowledge Sharing Culture; Information; Electronic Knowledge Network; Digital Tools; Software Development; Product Development; Ericsson; Cloud RAN; 5G; Case Study; Multi-Grounded Theory; Grounded Theory;

    Sammanfattning : Many organizations have realized the importance of managing what they know in a proper way, with the sharing of knowledge as one of the most central aspects. However, the practices of knowledge sharing are seldom fully understood, and thus implementations of technical systems intended to improve knowledge sharing have less effect than expected. LÄS MER

  4. 3. Reducing Power Consumption For Signal Computation in Radio Access Networks : Optimization With Linear Programming and Graph Attention Networks

    Master-uppsats, Linköpings universitet/Programvara och system

    Författare :Martin Nordberg; [2023]
    Nyckelord :Cloud RAN; Constrained optimization; Mixed integer linear programming; MILP; Machine learning; Graph neural network; Graph attention network; GAT;

    Sammanfattning : There is an ever-increasing usage of mobile data with global traffic having reached 115 exabytes per month at the end of 2022 for mobile data traffic including fixed wireless access. This is projected to grow up to 453 exabytes at the end of 2028, according to Ericssons 2022 mobile data traffic outlook report. LÄS MER

  5. 4. Improving the BBR congestion control algorithm for QUIC

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Alexander Chouchliapin; [2023]
    Nyckelord :congestion control; bbr; quic; algorithm;

    Sammanfattning : Congestion control is an important aspect of network technology, where traffic load is balanced to not cause an overflow in the system. Google has proposed its own protocol, QUIC, which is described as being set to supersede the TCP protocol. LÄS MER

  7. 5. Agile Planning Activities and Team Characteristics for On-time Delivery in Software Development Teams : A case study at Ericsson

    Master-uppsats, Linköpings universitet/Institutionen för ekonomisk och industriell utveckling

    Författare :Johanna Olander; Johanna Qvist; [2023]
    Nyckelord :Agile Methodologies; Agile variations; Agile planning; Effort Estimation; On-time delivery; Prioritization; Software development; Self-organized teams; Work Breakdown;

    Sammanfattning : The increase in complexity in software development is followed by higher pressure on several factors such as time-to-market. Software development projects are, however, found to often run over time due to many uncertainties throughout the project. LÄS MER
