Abstract: In a method of performing a network survey for a radio telecommunications network, signals from a location system external to the network are received for determining the location of the network survey device. The network survey device is located at a first location. Signals from a first base station of the network are received at the first location by the means of the network survey device, thereby measuring the synchronization of the first base station relative to a reference time-frame determined from the location system. The network survey device is moved to a second location. Signals from the first base station are received at the second location by the means of a network survey device, thereby measuring the synchronization of the first base station. The results of the measurements are compared with pre-determined network management criteria. Based upon the result of the comparison, the configuration of the network is modified.

Abstract: A radio system and a method of establishing a connection between network elements in a radio system comprising as network elements one or more base stations, a base station controller and a network management system that are operatively interconnected by means of telecommunication connections. Information between the network elements is transmitted in frames that are divided into time slots. The base station controller controls one or more base stations. Network element identification information has been fed into a network element to be installed, and the network element is physically connected to the system by means of the telecommunication connections.

Abstract: The invention relates to a radio system including one or more network elements, a base station controller and a network management system that are operatively interconnected by means of telecommunication connections, and to a method of testing telecommunication connections of a network element to be install in the radio system. Information between the network elements is transmitted in frames that are divided into time slots, and the base station controller controls one or more network elements being physically connected to the system by means of the telecommunication connections. To enable reliable and fast installation of the network elements, the network element transmits to the base station controller a message including information that the network element is ready to be tested. The base station controller initiates a testing procedure after receiving the message. The testing includes all channels between the base station controller and the network element.
