1. A server, comprising:

  • a processor, configured to;

    send, through a transmitter, a request message to obtain scenario information of a terminal to a base station,obtain, through a receiver, the scenario information of the terminal from a response message of the base station, so as to determine the scenario information of the terminal among a plurality of possible scenario information, the plurality of possible scenario information including carrier aggregation (CA) scenario information, coordinated multi-point (CoMP) scenario information, minimization of drive tests (MDT) scenario information, wide area network (WAN) scenario information, and wireless fidelity (WiFi) scenario information,determine a positioning measurement parameter according to the scenario information of the terminal determined by the processor,generate measurement configuration information carrying the positioning measurement parameter, andsend the measurement configuration information to the terminal through the transmitter,wherein the positioning measurement parameter is a parameter that the server requests the terminal to measure and is used to position the terminal, and the positioning measurement parameter determined by the processor comprises some or all of the following parameters which are selectively chosen depending on the scenario information of the terminal determined by the processor;

    a precoding matrix indicator (PMI)/rank indicator (RI) characteristic and the number of multiple paths of the terminal, a handover failure rate measured by the terminal, a radio link failure rate measured by the terminal, a signal to interference plus noise ratio of the terminal, and a number of cells from which the terminal receives strong interference;

    the transmitter, configured to send the measurement configuration information generated by the processor to the terminal through the base station; and

    a receiver, configured to receive, through the base station, configuration response information returned by the terminal, wherein the configuration response information carries a positioning response parameter, and the positioning response parameter is a measurement result generated after the terminal measures the positioning measurement parameter, whereinthe processor is further configured to position the terminal according to the positioning response parameter carried in the configuration response information received by the receiver,whereinthe processor is configured to, if the scenario information of the terminal comprises the CA scenario information, determine the signal to interference plus noise ratio of the terminal, the number of cells from which the terminal receives strong interference, and the PMI/RI characteristic and the number of multiple paths of the terminal as positioning measurement parameters.
