Five security groups exist in 3G networks as shown in the figure. • Network Access Security • Network domain security • User domain security • Application domain security • visibility, configurability of security. Network Access Security helps protect air interface and also provide 3g subscribers to access the 3g network securely. In UMTS authentication, key 'K' is shared between network and UE. 3G-UMTS Call Flow (Originating Call) User UE-RNC Sessions UTRAN RNC-Core Network Sessions Core EventStudio System Designer Equipment Network UE RNC MSC/VLR 06-Oct-13 07:24 (Page 1) A 3G-UMTS originating call is described here. Setup radio bearers and RANAP signaling are covered in detail. UMTS is designed to interoperate with GSM networks. To protect GSM networks against man-in-middle attacks, 3GPP is considering to add a structure RAND authentication challenge.

Security Information. UMTS provides enhanced security functions over GPRS, and thus extra security parameters are maintained in the UMTS SGSN MM contexts. Specifically, UMTS SGSN maintains authentication vectors, CK (currently used ciphering key), IK (currently used integrity key), and KSI (key set identifier).

Figures 3G UMTS bandwidth. UMTS uses wideband CDMA as the radio transport mechanism and the UMTS frequency channels are spaced by 5 MHz. The UMTS signal bandwidth is normally considered to be 5 MHz but this figure includes the 0.58 MHz guard bands either side. 3G Network - Analysis & Simulation. Analysis and simulation of UMTS, or Universal Mobile Telecommunications System, a 3rd generation mobile technology with increased spectral efficiency and high bandwidth can support greater data rates for voice and video data to the wireless end users.

3G security offers new security features and services. 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 The UMTS terrestrial radio access network (UTRAN) which handles the radio communication with 3G mobile phones.
Messages reporting session failure can be bookmarked in a PDF file, thus giving you quick access to the cause of failure. way security issues are addressed within these networks.
