SMS žinučių siuntimas FreeBSD serveryje / SMS Message Sending in FreeBSD Server

Firantas, Rimantas 03 September 2010 (has links)
Tikslas: FreeBSD serveryje konfigūruoti SMS žinučių siuntimą administratoriui, įvykus serverio sutrikimui. Analitinėje dalyje nagrinėjami aspektai: Programinės įrangos skirtos SMS žinučių siuntimui palyginimas; Techninių priemonių palyginimas; Internetinių sąsajų realizavimo būdai. Kuriamo produkto prototipai: FreeBSD serveris + GSM modemas - serveris sujungiamas su GSM modemu arba GSM telefonu ir SIM kortele. SMS žinutės siunčiamos naudojant GSM modemą; FreeBSD serveris + SMSC - serveryje įdiegiama speciali programa ir nustatoma darbui su SMSC serveriu, pvz., OMNITEL, per kurį bus siunčiamos SMS žinutės; FreeBSD serveris + SMS Gateway – naudojama komercinė SMS Gateway platforma, pasipildžius kreditus galima siųsti SMS žinutes. Technologinis sprendimas: Programavimui naudojama PHP kalba, HTML kalba, shell kalba. Panaudota programinė įranga: Gammu - programa SMS siuntimui ir įrašymui į duomenų bazę; Nagios - programa skirta pavojų nustatymams sutrikus serverio darbui; Macromedia Dreamweaver 8 – PHP ir HTML kalbos kodo rašymui; Apache – tinklo serverio kūrimui; MySQL – Gammu naudoja SMS žinučių laikymui ir gavimui. Naudotos UML diagramos: Administratoriaus panaudojimo atvejų diagrama; Sistemos procesų veikimo veiklos diagrama; Telefono numerio nustatymo veiklos diagrama; Sutrikimo atvejo nustatymo veiklos diagrama; Gaunamo SMS žinutės teksto nustatymo veiklos diagrama; Visų įrašų pažymėjimo veiklos diagrama; Įrašų šalinimo veiklos diagrama; Įrašų paieškos veiklos diagrama... [toliau žr. visą tekstą] / Project has been designed to alert administrators of disruption of the system, that he can get SMS messages every moment and to be able to know exactly what problems occurred in the system. On this project I analyzed and compared different software for sending SMS, analyzed the technical means for sending SMS. I choose Gammu and Nagios software which I make to interact with each other as one. To interact two different software helps shell script that uses configured SMS daemon. First software is Gammu which encompasses applications, scripts and drivers for managing various functions on cellular phones and similar devices. Second software is Nagios which in the event of a failure can alert administrator of the problem, allowing him to begin remediation processes before outages affect server processes. For sending SMS messages I used a device that can send SMS messages. Was chosen mobile phone SE W810i which is connected to the computer via a USB cable and seen directly in FreeBSD. MySQL relational database system - this Gammu uses to store/retrieve the SMS messages. Created web site where I can set phone numbers, several phones or just manage SMS storage. On SMS storage I can delete messages, or search for messages which I need. Web site is protected with password so on this web site can get in only administrator.

Analýza GSM sítě pomocí open source SW rádia / Analysis of GSM network, using open source SW radio

Kilian, Petr January 2013 (has links)
This master thesis is focused on analysis and creation of GSM network, using open-source projects. For such creation is used software defined radio – in this thesis kit USRP1 which uses OpenBTS with GNURadio. As a switchboard is used PBX Asterisk and for testing GSM network was used OsmocomBB (on Motorola C123) and Airprobe (on Nokia 3310) projects. Installation and implementation are part of this thesis. In thesis have been also created two scripts for simplify of the work with projects and one laboratory task.
