  1. 1. Time Synchronization for Ethernet Communication based Line Differential Protection

    Master-uppsats, KTH/Elkraftteknik

    Författare :Surya Seetharaman; [2017]
    Nyckelord :;

    Sammanfattning : Most of the industrial manufactures and designers of Power Substation Automation ProtectionControl products are under pressure regarding the existing communication architecture ofthe Line Dierential Protection Application. Currently the widely used technologies includeSONET/SDH which are circuit switched networks, that are no longer predominant. LÄS MER

  3. 2. Evaluation of a Set of TCP Features over Narrowband Radio Bearer for Train Communication

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Pajtim Buzolli; Jakub Tadeusz Mucha; [2016]
    Nyckelord :TCP; TCP Features; Circuit Switched; GSM-R; Packet Switched; GPRS; Train Communication; Technology and Engineering;

    Sammanfattning : An engineering approach to the evaluation of the TCP as a narrowband bearer for short messages in the low latency train-trackside communication scenario is described in this report. The project was developed in cooperation with Bombardier Transportation Sweden AB as a part of the “ETCS over GPRS” venture. LÄS MER

  4. 3. Fusion Network Performance: An Integrated Packet/Circuit Hybrid Optical Network

    Master-uppsats, KTH/Kommunikationssystem, CoS

    Författare :Edgar Gerardo Sanchez Gomez; [2013]
    Nyckelord :;

    Sammanfattning : IP traffic increase has resulted in a demand for greater capacity of the underlying Ethernet network. As a consequence, not only Internet Service Providers (ISPs) but also telecom operators have migrated their mobile back-haul networks from legacy SONET/SDH circuit-switched equipment to packet-based networks.

  5. 4. Home Location Register (HLR) dedicated for Short Message Service (SMS)

    Magister-uppsats, Institutionen för informationsteknologi

    Författare :Niklas Rönnblom; Johan Vikman; [2013]
    Nyckelord :;

    Sammanfattning : In telecommunication a Home Location Register (HLR) is used for keeping track of subscriber data for a multitude of services, including Circuit Switched (CS) calls, Short Message Service (SMS), and more. To support all functions, about 50 different complicated operations must be supported. LÄS MER

  7. 5. The Intelligent Use of Multiple Interfaces : Using multiplexing to reduce the overhead for small packets

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

    Författare :Niyaz Adigozalov; [2013]
    Nyckelord :Long-Term Evolution; LTE; multiplexing; VoIP; overhead; RTP; VPN; WLAN; Long-Term Evolution; LTE; multiplexa; VoIP; ooptimerad; RTP; VPN; WLAN;

    Sammanfattning : Long-Term Evolution (LTE) is the latest development in wide area cellular mobile network technology. In contrast with the earlier generations of circuit-switched mobile networks, LTE is all-IP packet-switched network. Both voice and data are sent inside IP packets. Voice over IP (VoIP) is used to provide voice service to LTE users. LÄS MER
