Combining circuit and packet based services in converging networks

Tämän diplomityön tavoitteena on tutkia sekä 3GPP:n standardoiman CSICS palvelun ensimmäisen vaiheen toiminnallisuutta että standardointiprosessin tilaa. Diplomityössä arvioidaan miten konferenssipalvelu voitaisiin toteuttaa käyttäen ensimmäisen vaiheen CSICS palvelua hyväksi. Työn alussa esitellään 3GPP:n standardointi prosessi, matkaviestinverkon kehitys sekä matkaviestinverkon kannalta tärkeitä standardointi organisaatioita. Tämän jälkeen esitellään ne lisäpalvelut, jotka vaikuttavat CSICS:n toimintaan sekä IMS-palveluympäristö. Seuraavaksi käydään läpi julkaistujen 3GPP:n standardien mukainen ensimmäisen vaiheen CSICS-toiminnallisuus. Lopuksi esitellään tunnistetut vaihtoehdot CSICS:ää hyödyntävän konferenssipalvelun toteutukseksi sekä vertaillaan esitettyjä vaihtoehtoja toisiinsa. Arviointi on suoritettu kirjallisuustutkimuksena. Tämän diplomityön tuloksena on kuvaus ensimmäisen vaiheen CSICS palvelun toiminnasta sekä arvio 3GPP CSICS:n standardoinnin tämänhetkisestä tilasta. Myös ensimmäisen vaiheen CSICS palvelua hyödyntävän konferenssipalvelun toteuttaminen on päätelty mahdolliseksi ja tunnistetuista toteutusvaihtoehdoista on valittu toteutettavaksi soveltuvimmat.The aim of this thesis is to study the functionality and the current status of the 3GPP CSICS phase 1 specifications. This thesis also evaluates how the conferencing service could be implemented with the CSICS phase 1 functionality. First the standardization procedure of the 3GPP, the development of the mobile network and some important bodies involved in the standardization of the mobile network are introduced. Thereafter the supplementary services that have an effect on the CSICS functionality and the IMS are presented. Next the current specifications of 3GPP regarding the CSICS are studied. Last the different approaches of implementing a conference service based on these specifications are evaluated. The evaluation is based on a literature study. As a result, the functionality described in the CSICS phase 1 specifications and evaluation of the state of the the standardization of the CSICS phase 1 are presented. Also the conference service is determined to be feasible to implement utilising the CSICS phase 1 functionality. From the recognised approaches the most suitable ones for implementation are chosen

ILC Reference Design Report Volume 4 - Detectors

This report, Volume IV of the International Linear Collider Reference Design Report, describes the detectors which will record and measure the charged and neutral particles produced in the ILC's high energy e+e- collisions. The physics of the ILC, and the environment of the machine-detector interface, pose new challenges for detector design. Several conceptual designs for the detector promise the needed performance, and ongoing detector R&D is addressing the outstanding technological issues. Two such detectors, operating in push-pull mode, perfectly instrument the ILC interaction region, and access the full potential of ILC physics.This report, Volume IV of the International Linear Collider Reference Design Report, describes the detectors which will record and measure the charged and neutral particles produced in the ILC's high energy e+e- collisions.

ILC Reference Design Report Volume 3 - Accelerator

The International Linear Collider (ILC) is a 200-500 GeV center-of-mass high-luminosity linear electron-positron collider, based on 1.3 GHz superconducting radio-frequency (SCRF) accelerating cavities. The ILC has a total footprint of about 31 km and is designed for a peak luminosity of 2x10^34 cm^-2 s^-1. The complex includes a polarized electron source, an undulator-based positron source, two 6.7 km circumference damping rings, two-stage bunch compressors, two 11 km long main linacs and a 4.5 km long beam delivery system. This report is Volume III (Accelerator) of the four volume Reference Design Report, which describes the design and cost of the ILC.The International Linear Collider (ILC) is a 200-500 GeV center-of-mass high-luminosity linear electron-positron collider, based on 1.3 GHz superconducting radio-frequency (SCRF) accelerating cavities.
