BACKGROUND OF THE INVENTION Guaranteeing service continuity of mobile users is a basic function of a cellular mobile communication system, and handover of a mobile station serving cell is a primary means of ensuring service continuity. In order to facilitate the handover of the user equipment (UE, User Equipment), the system needs to configure the adjacency relationship for each cell, so that the network side notifies the neighboring area information to the user equipment; the user equipment measures the neighboring area according to the neighboring area information and reports the measurement result. The network side then instructs the user equipment to switch to a neighboring area according to the reported measurement result. The neighboring areas around a certain cell are not only related to the distance of the cell, but also closely related to the wireless environment in which the cell is located. Due to the intricacies of the wireless environment, especially in the dense urban environment of high-rise buildings, it is difficult to determine exactly which neighboring areas should be configured in a certain area in the initial stage of network planning. In addition, if a new cell or cell attribute change is added in the system, the neighbor relationship of the cell is not updated in time, or the environment changes, the omission of the network planner, etc., the information of the neighboring area is not updated in time. In this way, the user equipment cannot switch to other cells in time, and the load of the cell is too high, the signal quality of the cell is deteriorated, the interference is serious, or the user drops the call. Therefore, the topic of ANR (Automatic Neighboring Relationship Function) has been introduced in the 3GPP conference.

That is, referring to FIG. 1 , after the step S104, the method further includes: Step S106: The RNC determines the next execution step according to the measurement result. In an embodiment, the RNC sends a notification message to notify the UE in different states whether to perform ANR measurement. Preferably, the UE may be notified by using a new message or an existing system broadcast message or a measurement control message as a notification message. ANR measurement. Further, the RNC may carry an indication of the user status in the notification message, and notify the UE in the user state whether to perform ANR measurement according to the indication of the user status. For example, whether the UE in the IDLE state performs the ANR measurement by using the notification message carrying the IDLE status indication, or whether the UE in the URA_PCH state performs the ANR measurement by using the notification message carrying the URA_PCH status indication, or uses the notification carrying the CELL_PCH status indication. The message informs the UE in the CELL_PCH state whether to perform ANR measurement. In the implementation, the indication of the user status is expressed as follows: The user status is a newly added cell, and different bit positions are used to represent different user states; and the following can also be expressed in the following manner: Each status indication in the indication of the user status corresponds to A new cell. When the first representation is used, the user status is a new cell, and different bits are used to represent different user states. Preferably, bitO can be used to represent the IDLE state, bitl represents the URA_PCH state, and bit2 represents the CELL_PCH state. .

Preferably, when the newly added cell is TRUE, it indicates that the corresponding status needs to be measured; when the newly added cell has a value of FALSE When it is indicated, the corresponding state does not need to be measured. In summary, when the cell indicating the corresponding state includes and/or takes a value of TRUE or indicates other values as needed, it indicates that the corresponding state needs to be measured; when the indicated state cell is not included or the value is FALSE or indicates When other values are not needed, it means that the corresponding state does not need to be measured. When implemented, the notification message may also include: The physical quantity of the measurement. The measured physical quantity includes at least one of the following: a ratio of common pilot channel chip energy to band-limited white noise power spectral density, common pilot channel received signal code power, primary common control physical channel received signal code power, and time slot letter The number power interferes with the path loss. As shown in FIG. 1 , in step S104 , the UE measures the measured physical quantity, and reports the measurement result to the RNC, where the measurement result is carried in the additional additional measurement report message, or carried in the existing RRC (Radio Resource Control, Radio resource control) Message reporting.
