GSM-Lyhytsanomat Mittarinluennassa (GMS Short Message Service in Automatic Meter Reading).

摘要

This report presents a way to use GSM Short Messages for Automatic Meter Reading. For this purpose, a specification for message structure is defined. Using these messages, it is possible to send instructions to remote meters to make specific measurements and send the results. The message structure includes also possibility to send other telecommands. Monitoring and setting of remote clock is also possible. One important factor in designing the message structure is to avoid unnecessary transmission of messages as much as possible. The operation of these messages is tested in field tests. Reliability of mobile phones and the GSM network is tested. Throughput and applicability of the whole system for the remote meter reading is monitored and evaluated.
