Procedures implemented. Tasks of the MSC include: 3G Network architecture • 3G is to prepare a universal infrastructure able to carry existing and future services. • Separation of access technology, transport technology, service technology. • The network architecture can be divided into subsystems based on the nature of traffic, protocol structures, physical elements. • Conceptual Security Information.

GSM Mobile Originated Call Flow - Explore MoreGSM call setup is analyzed in detail. The role of each participant is documented with a separate call flow. 3G UMTS Core Network. The 3G UMTS core network architecture is a migration of that used for GSM with further elements overlaid to enable the additional functionality demanded by UMTS. In view of the different ways in which data may be carried, the UMTS core network may be split into two different areas: 3G Security Features (1) Mutual Authentication The mobile user and the serving network authenticate each other Data Integrity Signaling messages between the mobile station and RNC protected by integrity code Network to Network Security Secure communication between serving networks.

IuPS interface works between the UMTS RNC (Radio Network Controller) and the SGSN (Serving GPRS Support Node) supporting UMTS integrated services such as multimedia and global roaming to mobile users. IuCS interface in UMTS links the RNC (Radio Network Controller) with a 3G MSC (3G Mobile Switching Centre).

IPsec suggested Wider Security Scope existing mobile systems and to develop a new security architecture specifically to be used in UMTS. This early work was subsequently taken forward into the Third Generation Partnership Project (3GPP) and this will be the basis for the Release 99 deployment of 3G systems. GSM GPRS Sequence Diagrams.

and execution of studies in the process of constructing as well as evaluating computer appropriate levels of security for that team's software products. To this

This page covers UMTS (3G) to WLAN handover.It also mentions WLAN (WiFi) to UMTS (3G) handover with message flow diagram. The handover to WiFi network has become popular due to following benefits of wifi based networks. • WiFi networks are low cost.

WCDMA is used for the radio interface of UMTS. It Call flow is how signaling and sessions are established across an LTE network. We will have a look at the call flow diagrams about different procedures in LTE which includes basic registration, Carrier Aggregation (band addition and removal), 4x4 MIMO activation, SMS etc. What is the difference between UMTS, 3G and EDGE networks? These are different network standards that build on the success of GSM, and the difference mainly pertains to speed. The Universal Mobile Telecommunications System (UMTS) is one of the new ‘third generation’ 3G mobile cellular communication systems. GSM & UMTS security, Authentication from MS to BTS.

Elections in 3GPP are held every two years, with the officials GPRS(2g) UMTS(3g) LTE(4g) Architecture Diagram. I am adding the architecture diagram of 2g, 3g, 4g for reference. The source of these pictures are Spirent and Squaretek. Thanks :) Hope it will be useful to others also :) Article by Carol Chiang. 3.

It should be noted that the main objective of 3G security architecture is not to provide a completely secure system, but to build a system that is flexible to adapt to new challenges [3]. This paper is organized as follows: In Section II we present and discuss the security threats of mobile PSTN to IMS call flow.
