  1. 1. GSM HLR Unstructured Supplementary Service Data (USSD) service

    Master-uppsats, Institutionen för informationsteknologi

    Författare :Mohammedreza Taghilu; [2013]
    Nyckelord :;

    Sammanfattning : The Unstructured Supplementary Service Data (USSD) provides a service additional to GSM main service (teleservices and bearer services). Similar to its counterparts, Mobile Station (MS) user and entities of GSM network operator  act as main roles in order to establish communication in which the message traffic is transparent for the mentioned actors.

  3. 2. Signaling Over Protocols Gateways in Next-Generation Networks

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Författare :Gbenga Segun Akinwande; [2009]
    Nyckelord :Signaling; Protocols Gateways; SS7; ATM; SIGTRAN; UMTS; Simulation ;

    Sammanfattning : In this thesis, I examined various signalling both in wired and mobile networks, with more emphasis on SIGTRAN. The SIGTRAN is the protocol suite applicable in the current new generation and next-generation networks, most especially as it enables service provider to be able to interpolate both wireline and wireless services within the same architecture.

  4. 3. Evaluation of UDP and SCTP for SIP-T and TCP, UDP and SCTP with constant traffic

    Master-uppsats, Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

    Författare :Muhammad-Sarfraz Zafar; Muhammad-Shoaib Gill; [2009]
    Nyckelord :LaCcviLm ;

    Sammanfattning : In recent years, Voice over IP (VoIP) has gained a lot of popularity. Signaling being an important part of VoIP has been addressed by the (IETF) SIGTRAN working group to meet Quality of Service as given by Public Switched Telephone Network (PSTN), so that both PSTN and VoIP can co-exit and work together in a seamless manner SIP (Session Initiation Protocol) developed by IETF for VoIP signaling is a communication control protocol capable of running on different transport layers, e.

  5. 4. SIGTRAN : Signaling over IP -- a step closer to an all-IP network

    Master-uppsats, KTH/Mikroelektronik och Informationsteknik, IMIT

    Författare :Mia Immonen; [2005]
    Nyckelord :SIGTRAN; all-IP network; signaling; SCTP; failover;

    Sammanfattning : The mass popularization of telecommunication services in recent years have resulted in a heavily loaded signaling network. The Signaling System number 7 (SS7) is used in fixed and wireless networks and is needed for call control and services such as caller ID, roaming, and for sending SMS. LÄS MER

  7. 5. Experimental Study of GPRS/WLAN Systems Integration

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Joakim Nyström; Mikael Seppälä; [2003]
    Nyckelord :Informationsteknik; GPRS; WLAN; Integration; RADIUS; MobileIP; OTP; SMS; SS7; SIGTRAN; Informationsteknik;

    Sammanfattning : The convergence of future networks relies on the evolution of technology that enables seamless roaming abilities across non-heterogenous networks for mobile clients. This thesis presents an experimental study of a GPRS-WLAN integration scenario where the objective is to analyze various aspects of the issues related to charging, mobility, roaming and security between GPRS and WLAN networks.
