    Sammanfattning : Internet Protocol multimedia subsystem (IMS) is an architecture for services such as voice over Internet Protocol (VoIP) in IP based communication systems. IMS is standardized by the 3GPP standardization forum, and was first released in 2002. Since then IMS has not had the wide adoption by operators as first anticipated. LÄS MER

  3. 2. Vilken Open Source SIP-server lämpar sig bäst förAndroid?

    Kandidat-uppsats, Linköpings universitet/Interaktiva och kognitiva system; Linköpings universitet/Tekniska högskolan

    Författare :Marcus Hellgren; Ida Enbrant; [2014]
    Nyckelord :SIP; VoiP; Android;

    Sammanfattning : Denna studie tacklar ett av de problem som modern IP-telefoni brottas med, som gör att det är svårare att konkurrera med traditionell telefoni: fördröjningar på grund av otillräckliga Session Initiation Protocol-servrar (SIP). Genom tester av de viktigaste faktorerna jämförs fyra högaktuella Open Source SIP-servrar: OpenSIPS, Kamailio, FreeSWITCH och Yate. LÄS MER

  4. 3. Distribution of Context Information using the Session Initiation Protocol (SIP)

    Master-uppsats, KTH/Kommunikationssystem, CoS

    Författare :Carlos Angeles Piña; [2008]
    Nyckelord :Context-awareness; Context Information Distribution; SIP; SIMPLE;

    Sammanfattning : Context-aware applications are applications that exploit knowledge of the situation of the user (i.e. the user’s context) to adapt their behavior, thus helping the user achieve his or her daily tasks. Today, the transfer of context information needs to take place over unreliable and dynamically changing networks. LÄS MER

  5. 4. Context-aware applications for a Pocket PC

    Master-uppsats, KTH/Kommunikationssystem, CoS

    Författare :Yu Sun; [2007]
    Nyckelord :Context; Context-aware; Pocket PC; reminder; SIP; SIMPLE; XML; PIDF;

    Sammanfattning : With the rapid development of technology for context awareness, pervasive computing is releasing people from their traditional desktops. Since mobile devices feature portability and are (nearly) always connected, people tend to carry them wherever they go. LÄS MER

  7. 5. A Presence Server for Context-aware Applications

    Master-uppsats, KTH/Kommunikationssystem, CoS

    Författare :Mohammad Zarifi Eslami; [2007]
    Nyckelord :Context; Context-aware; SIP; SIP-SIMPLE; XML; PIDF; SER; Presence Agent module; Subscribe message; Publish message; Notify message;

    Sammanfattning : This master’s thesis project “A Presence Server for Context-aware Applications” was carried out at KTH Center for Wireless Systems (Wireless@KTH). The overall goal of this thesis project is to implement a context aware infrastructure to serve as middleware for different kinds of context aware applications, such as a context-aware printing application, location based notifier application, etc. LÄS MER
