A logged measurement reconfiguration test method, comprising: a network side sending a new logged measurement configuration to a terminal when the terminal already has a logged measurement configuration; characterized by, the network side detecting whether there is a measurement log for the logged measurement configuration that the terminal already had, and if yes, the test fails, otherwise the network side detecting whether there is a measurement log for the logged measurement configuration that the terminal already had after the terminal enters into an idle state and stays there for a specified period of time; wherein, the step of the network side detecting whether there is a measurement log for the logged measurement configuration that the terminal already had comprises: the network side sending a terminal information request message carrying a logged measurement report request flag to the terminal, and judging whether a terminal information response message returned by the terminal carries a logged measurement report for the logged measurement configuration that the terminal already had; wherein, the network side judges whether the logged measurement report carried in the terminal information response message is for the logged measurement configuration that the terminal already had in the following manner: the network side detects whether an absolute time stamp in the logged measurement report is consistent with an absolute time stamp in the logged measurement configuration that the terminal already had. a network side sending a new logged measurement configuration to a terminal when the terminal already has a logged measurement configuration; characterized by, the network side detecting whether there is a measurement log for the logged measurement configuration that the terminal already had, and if yes, the test fails, otherwise the network side detecting whether there is a measurement log for the logged measurement configuration that the terminal already had after the terminal enters into an idle state and stays there for a specified period of time; wherein, the step of the network side detecting whether there is a measurement log for the logged measurement configuration that the terminal already had comprises: the network side sending a terminal information request message carrying a logged measurement report request flag to the terminal, and judging whether a terminal information response message returned by the terminal carries a logged measurement report for the logged measurement configuration that the terminal already had; the network side sending a terminal information request message carrying a logged measurement report request flag to the terminal, and judging whether a terminal information response message returned by the terminal carries a logged measurement report for the logged measurement configuration that the terminal already had; wherein, the network side judges whether the logged measurement report carried in the terminal information response message is for the logged measurement configuration that the terminal already had in the following manner: the network side detects whether an absolute time stamp in the logged measurement report is consistent with an absolute time stamp in the logged measurement configuration that the terminal already had. the network side detects whether an absolute time stamp in the logged measurement report is consistent with an absolute time stamp in the logged measurement configuration that the terminal already had.
