GPRS Based Data Collection

In some cases Users simultaneously require the on-line nature of direct data collection and the flexibility of remote data collection (by installation of data collection device). This is where the GPRS data collection device might be useful.

For many people GSM instantly refers to mobile phone calls. However, GSM is not only about transferring speaking voice among people, but about the mobile based data communication among electronic devices too, which is a very quickly advancing element of GSM. The mobile M2M (machine-to-machine communication) data transfer is solidly spreading, special, industrially constructed devices and solutions are starting to be utilized by previously averse areas.

Up to this point the only expectation for GSM modems was to be able to complete AT (standard modem communication protocol stack) tasks coming from the joint external devices and forward the information to the processor server through sound, SMS, fax, circuit switch data connection (CSD) or general packet radio service (GPRS). For countless currently used applications this functionality proved to be sufficient. This is what the Siemens GSM Engine based Audiotel Industrial Base is capable of (it also utilises the protocol stack of Siemens GSM Engine).

With the aid of the appliance used by CompArgo, the Audiotel Industrial Plus even user applications are runnable on GSM appliances. CompArgo employs its self-developed data collection application to operate and execute the following procedures:

  • data collection;
  • if necessary: temporary data storage;
  • data transfer.

Such a modem (data collection device, if its software is already installed) is a compact and reliable data communication device.

The device collects CDRs arriving from the telephone centre via COM port, puffers and compresses them, then forwards the packages to the server with GPRS protocol. The device maintains on-line connection with the base station, but it only logs into the server, if collected data exists. If there is no freshly collected data to transfer, the device logs into the server every two hours, so its proper functioning can be verified, even in periods without any traffic. The most common utilization of the GPRS data collection device is the use of CAnet Service. In this case a telecom tariffing system suited for the User’s needs immediately processes the records, so – disregarded the data transmission and processing time (2-6 minutes) – in confines of the CAnet System the Customer has the opportunity of querying the traffic (corresponding to his or her authority) on-line.
