TEMS Investigation TEMS Investigation is a drive test tool within the TEMS product family. It consists of a TEMS mobile station, a PC with the TEMS Investigation software and a GPS receiver. The uplink and downlink information on the air-interface is monitored and recorded together with the positioning data from the GPS. TEMS Investigation, here referred to as TEMS, is a very powerful tool for field measurements during troubleshooting in specific areas of the network. MTR Mobile Traffic Recording (MTR) records the events and measurements on both the uplink and downlink connected to a certain subscription, which can be useful when a subscriber complains and the cause is to be investigated. MTR is also very useful together with TEMS. From TEMS geographical information can be retrieved but not from MTR. CER Channel Event Recording (CER) measures interference on the frequencies defined in the cell and is used when the performance of the channel allocation strategy is investigat...

STS: Statistics and Traffic Measurement Subsystem (STS) is implemented in the BSC (and MSC). It gives statistics about events in different parts of the system such as cells and equipment. By continuously supervising the results from STS the operator can obtain a very good overview of the radio network performance which can help to detect problems early. For further information, MRR Measurement Result Recording (MRR) collects information from the measurement results sent by the BTSs to the BSC. Information such as RXLEV, RXQUAL etc. is included. The tool is for instance used for routine supervision or for checking specific cells. MRR is a part of the Radio Network Optimization (RNO) package in OSS TEMS Automatic Tems Automatic is a tool within the TEMS product portfolio, where several special mobile stations are placed in for instance taxis and buses. The set of mobiles are supervised centrally and the measurements are sent directly to this center. TEMS automatic provides the ...
