Location Update Procedure
Location Update Procedure In order to make a mobile terminated call, The GSM network should know the location of the MS (Mobile Station), despite of its movement. For this purpose the MS periodically reports its location to the network using the Location Update procedure. Location Area (LA) A GSM network is divided into cells. A group of cells is considered a location area. A mobile phone in motion keeps the network informed about changes in the location area. If the mobile moves from a cell in one location area to a cell in another location area, the mobile phone should perform a location area update to inform the network about the exact location of the mobile phone. The Location Update procedure is performed: When the MS has been switched off and wants to become active, or When it is active but not involved in a call, and it moves from one location area to another, or After a regular time interval. Location registration takes place when a mobile station is turned on. This is also known as IMSI Attach because as soon as the mobile station is switched on it informs the Visitor Location Register (VLR) that it is now back in service and is able to receive calls. As a result of a successful registration, the network sends the mobile station two numbers that are stored in the SIM (Subscriber Identity Module) card of the mobile station. These two numbers are:- 1. Location Area Identity (LAI) 2. Temporary Mobile Subscriber Identity (TMSI). The network, via the control channels of the air interface, sends the LAI. -

Security for the Core Network of Third Generation Mobile Systems
Security for the core network of third generation mobile systems GUNTER HORN, DIRK KROSELBERG Siemens AG, Corporate Technology, D-81730 Muenchen, Germany STEFANPUTZ T-Mobil, P.O. Box 300463, D-53184 Bonn, Germany ROLAND SCHMITZ T-Nova Technology Centre, D-64307 Darmstadt, Germany Keywords: UMTS, MAP Security, Multimedia domain, SIP, IPSec, IKE, Key Management Abstract: This contribution gives a survey of the present standardisation activities by 3GPP (3'd Generation Partnership Project1) in the area of security for signalling in the core network of third generation mobile systems. We give an overview of the protocols that need to be secured, present the basic principles behind the overall security architecture and describe the key management and format of secured messages, as far as they have already been finalised. In particular, we address core network security aspects of the 3GPP multimedia domain. 1 3GPP was formed by regional standards organisations from Europe, Asia and North America to produce specifications for a third generation mobile system named UMTS which is designed to evolve from GSM core network. There is a competing effort known as 3GPP2 with partners from North America and Asia. The original version of this chapter was revised: The copyright line was incorrect. This has been corrected.

THREATS TO CORE NETWORK SECURITY FOR MOBILE RADIO NETWORKS The core network of mobile radio systems is the part of the network which is independent of the radio interface technology of the mobile terminal. -
2G GSM GPRS Network Lab Simulation
2G GSM GPRS Network Lab Simulation Overview GL offers an End-to-End 2G and 2.5G GSM GPRS Wireless Network Simulation Test Suite with all components such as Base Station, RF channel, GSM core network elements such as BSC, MSC, HLR, and GPRS core elements such as SGSN, and GGSN to support mobile call and traffic emulation. The lab system can operate with real mobiles, or simulator user profiles. By mimicking real-world customer behavior in lab environments, our solutions allow mobile operators and equipment manufacturers to verify their wireless networks before deployment. In other words, one can setup a virtual real-time network simulating all the network elements using “MAPS 2G Wireless Lab Suite”. The test suite supports simulation ofGSM Abis, A, C/D/E, Gb, and GnGp interfaces. In addition, with MAPS™ HD RTP appliance you can generate high call intensity (hundreds of calls/sec) and high volume Voice and SMS calls (thousands of simultaneous calls/platform). MAPS™ supports automated stress/load testing capabilities through Load Generation and Bulk Call Simulation features. To perform Bulk Call Generation, several UE/Subscriber configuration files are required. The UE/Subscriber configuration files can becreated using regular Profile Editors (XML Based), using CSV based profiles, or using Auto Generation feature for simulating inter-networking calls, roaming calls, data sessions, and bulk GTP traffic generation. Complete 2G GSM lab simulation can be realized using GL’s Remote MAPS™ feature, a client server module, designed for multi-node multi-interface simulation from a single GUI. The application has the ability to remotely control multiple MAPS™ Servers running on different PCs from a single remote client application. -

Cellular Technologies Mobile Device Investigations Program Technical Operations Division - DFB DHS - FLETC Basic Network Design Frequency Reuse and Planning 1. Cellular Technology enables mobile communication because they use of a complex two-way radio system between the mobile unit and the wireless network. 2. It uses radio frequencies (radio channels) over and over again throughout a market with minimal interference, to serve a large number of simultaneous conversations. 3. This concept is the central tenet to cellular design and is called frequency reuse. Basic Network Design Frequency Reuse and Planning 1. Repeatedly reusing radio frequencies over a geographical area. 2. Most frequency reuse plans are produced in groups of seven cells. Basic Network Design Note: Common frequencies are never contiguous 7 7 The U.S. Border Patrol uses a similar scheme with Mobile Radio Frequencies along the Southern border. By alternating frequencies between sectors, all USBP offices can communicate on just two frequencies Basic Network Design Frequency Reuse and Planning 1. There are numerous seven cell frequency reuse groups in each cellular carriers Metropolitan Statistical Area (MSA) or Rural Service Areas (RSA). 2. Higher traffic cells will receive more radio channels according to customer usage or subscriber density. Basic Network Design Frequency Reuse and Planning A frequency reuse plan is defined as how radio frequency (RF) engineers subdivide and assign the FCC allocated radio spectrum throughout the carriers market. Basic Network Design How Frequency Reuse Systems Work In concept frequency reuse maximizes coverage area and simultaneous conversation handling Cellular communication is made possible by the transmission of RF. This is achieved by the use of a powerful antenna broadcasting the signals. -

Location Update and Paging in Wireless Networks — Location Management Plays the Central Role in Providing Ubiquitous Communica
Location Update and Paging in Wireless Networks Paging • Paging is the one-to-one communication between the mobile and the base station • Paging is a procedure the network uses to find out a subscriber's location before actual call establishment. • Paging is used to alert the mobile station of an incoming call — Location management plays the central role in providing ubiquitous communications services in the future wireless mobile networks. Location update and paging are commonly used in tracking mobile users on the move, location update is to update a mobile user’s current location while the paging is used to locate a mobile user, both will incur signaling traffic in the wireless networks. The more frequent the location updates, the less paging in locating a mobile user, thus there is a tradeoff in terms of signaling cost There are two basic operations for tracking a mobile user: location update and terminal paging. Location update is the process for the mobile terminals to report their locations to the network, thus all mobiles are actively sending location update messages to keep the network informed. Terminal paging is the process for the network to search the called terminal by sending polling signals to cells close to the last reported location of the called terminal. When an incoming calls to a mobile user (we will use mobile user and mobile terminal interchangeably) arrives, the wireless network simply routes the call to the last reported location of the mobile terminal. Intuitively, the location accuracy depends on the location update frequency, the more often the location updates, the more accurate the location information. -
