Short Message Service Principes et Architecture
1 1 Architecture du service SMS point à point La figure 1 présente un exemple d’architecture SMS L’architecture de ce service est constituée des entités suivantes : • Gateway MSC For Short Message Service (SMS-GMSC) : Il s’agit d’une fonction capable d’une part de recevoir un message court d’une entité SMSC et d’interroger le
IP Multimedia Subsystem : Principes et Architecture
d’accès connecté à un réseau IP (e g , GPRS, UMTS, WLAN, xDSL, câble, etc) • Garantie Qos des services multimédia : Sur Internet, le type de QoS fourni est best effort Cela ne sera pas le cas avec l’IMS Les réseaux d’accès et de transport de l’IMS fournissent la QoS de bout-en-bout

A Survey on Security for Mobile Devices - WPI
o GPRS: Attacks against GPRS can target the device, the radio access network, the backbone network, and the interfaces connecting GPRS networks with each other or with the Internet - Five sensitive area in GPRS security the mobile station (MS) and the SIM-card the interface between the MS and the SGSN (Serving GPRS Support Node)
IP Technology in 3 Generation Mobile Networks
GPRS, UMTS, IMS Part II Part I Trends in Mobile Networks: • IP transport in the backbone • Transport voice & data over IP • Push IP into the RAN • Terminate IP in the mobile host • Separation: Transport ↔Control Trends in the Internet: • Enable wireless access • Support mobility • QoS beyond “Best Effort” • Security and AAA
The Usability of Green Building Rating Systems in Hot Arid
credits GPRS requires compliance with Egyptian and US codes and standards in the same time This creates many conflicts and requires huge preparation effort For example, the energy efficiency and indoor air quality credits require compliance with ANSI/ASHRAE/IESNA and HBRC standards On the other side, there is an over simplification in many
