Garg, in Wireless Communications & Networking, 2007 13.8.2 Security in GPRS. The general packet radio service (GPRS) allows packet data to be sent and received across a mobile network (GSM). GPRS can be considered an extension to the GSM network to provide 3G services. GPRS has been designed to allow users to connect to the Internet, and as such is an essential first step toward 3G • Each carrier frequency divided in time, using TDMA • Fundamental unit of time in this TDMA scheme is a burst period approx. 0.577 ms long • Eight burst periods are grouped into a TDMA frame (approx. 4.615 ms) = basic unit for the definition of logical channels • A physical channel is one burst period per TDMA frame Serietitel och serienummer Title of series, numbering ISSN — Titel Title Dubbel Differentiell TOA Positionering för GSM Double Differential TOA Positioning for GSM Författare Author Andreas Nordzell Sammanfattning Abstract For most time-based positioning techniques, synchronization between the objects in the sys-tem is of great importance. data in bursts using time slo ts allocated for each link. The capacity of the link is varied from 14.4 Mbps to 28.8 Mbps so that utilization is v aried from 1.0 to 0.5. TDMA Frame f1 TS 0. TS 1. TS 2. TS 3. TS 4. TS 5. TS 6. TS 7. 1 TDMA frame 1 physical channel. Each timeslot on a TDMA frame is called a physical channel Therefore there are 8 physical channels per carrier frequency Physical channels can be used to transmit speech, data or signaling information

Each of the eight bursts, that form a TDMA frame, are then assigned to a single user. 5.2.2 Channel structure. A channel corresponds to the recurrence of one burst every frame. It is defined by its frequency and the position of its corresponding burst within a TDMA frame. In GSM there are two types of channels:

One GSM hyperframe composed of 2048 superframes. Each GSM superframe composed of multiframes (either 26 or 51 as described below). Each GSM multiframe composed of frames (either 51 or 26 based on multiframe type). Each frame composed of 8 time slots. Hence there will be total of 2715648 TDMA frames available in GSM and the same cycle continues. Handover from GSM to UMTS / WCDMA: This form of handover is supported within GSM and a "neighbour list" was established to enable this occur easily. As the GSM / 2G network is normally more extensive than the 3G network, this type of handover does not normally occur when the mobile leaves a coverage area and must quickly find a new base station to maintain contact.

Ecstasy er et kunstigt fremstillet stof, og blev oprindeligt (i 1898) fremstillet som et middel til at dæmpe appetitten. I Danmark blev stoffet populært op gennem 1990’erne, og det forbindes ofte med fest og utrættelig dans. Ecstasy betegnes af mange som et typisk feststof, da mange oplever en positiv indflydelse på de sociale egenskaber, humør og evne til at nyde musik og dans.Ren

The GSM TDMA frame numbers are first correlated with the GPS clock signal. Optionally, this correlation is adjusted using the… A telecommunications system and method for rapid start-up of a Global Position System (GPS) receiver integrated with a mobile terminal is disclosed. Other types of PLMN are the time division multiple access (TDMA) network or code division multiple access (CDMA) network.

GSM uses a combination of both TDMA and FDMA techniques. The FDMA element involves the division by frequency of the (maximum) 25 MHz bandwidth into 

GSM Radio Link (Cont) 890-915 MHz uplink, 935-960 MHz downlink 25 MHz ⇒124 × 200kHz Channels Each channel is TDMA with burst (slot) period of 15/26 ms. Eight burst periods = TDMA frame of 120/26 ms. One channel = one burst period per TDMA frame. 26 TDMA frames ⇒one Multiframe 24 are used for traffic, 1 for control, and 1 is unused. TDMA : Frame Structure TDMA requires a centralized control node, whose primary function is to transmit a periodic reference burst that defines a frame and forces a measure of synchronization of all the users. The frame so-defined is divided into time slots, and each user is assigned a Time Slot in which to transmit its information. T F T S
