This article describes a proposal of the probe application used for 2G-4G mobile network coverage and speech quality measurement. It is based on Android platform, most commonly used operation system for mobile phones. Measured results are visualized in the form of a map using GPS location. There are few tests available focusing on the applications that are most often used: test of the network coverage, speed of the websites loading, data rate test and voice quality test. The results are analyzed directly in the application and are also available over the web interface form. Individual results can be exported to standard output .csv, .json and .xml formats for further analysis.

“…The intrusive methods use the original sound sample as it has entered the communication channel and compare it with the degraded signal in the output. One of the most known intrusive methods is the Perceptual Evaluation of Speech Quality (PESQ) method according to ITU-T P.862 [6,7].…”

“…OpenBTS is able to convert and distribute this Internet connection as a mobile network across a large geographic region. This solution is suitable for building GSM in extreme conditions and the achieved PESQ quality [4] of such solution is presented in several papers [5,6]. Any mobile phone connected to this network can transmit basic data, use voice services or send text messages.…”

“…[11] The tested GSM infrastructure was built on Universal Software radio Peripheral (USRP N210) hardware [8] from Ettus Research ™ in combination with Daughterboard WBX. The performance parameters inside [2] and outside [3] our laboratory were observed. The next logical step was to interconnect the BTS station with the rest of the world.…”

The paper is focused on the building ad-hoc GSM network based on open source software and low-cost hardware. The created Base Transmission Station can be deployed and put into operation in a few minutes in a required area to ensure private communication between connected GSM mobile terminals. The convergence between BTS station and the other networks is possible through IP network. The paper tries to define connection parameters to provide sufficient quality of voice service between the GSM network and IP Multimedia Subsystem. The paper brings practical results of voice call quality measurement between users inside BTS station mobile network and users inside IP Multimedia Subsystem network. The calls are simulated by low-cost embedded solution for speech quality measurement in GSM network. This tool is under development of our laboratory and allows automatic speech quality measurement of any GSM or UMTS mobile network. The Perceptual Evaluation of Speech Quality method is used to get final comparable results. The communication between BTS station and connected networks has to be secured against the interception from the third party. The influence of the securing method for quality of service is presented in detail. Paper, apart from the quality of service measurement section, describes technical requirements for successful interconnection between BTS and IMS networks. The authentication, authorization and accounting methods in roaming between BTS and IMS system are presented too.
