If the UE uses a measurement interval (also called an autonomous measurement interval) to measure the CGI of Cell2 ', but Cell2 does not know that the UE initiates the measurement interval. During the measurement interval, it is possible that Cell2 cannot receive the acknowledgment (ACK) message or the non-acknowledgement (NACK) message for the downlink data sent to the UE. Cell2 repeatedly sends useless data to the UE or deletes the link configuration. In Cell2, it may be considered that the UE has disconnected the link with Cell2 and stops sending data to the UE, and deletes the UE's link configuration in Cell2.

When Cell1 configures the UE to perform ANR cell measurement on Cell2's neighboring cell Cell2 ', if Cell2 knows that Cell1 configures the UE to perform ANR cell measurement on Cell2', and the UE will start the measurement interval (or autonomous measurement interval), and know the measurement The length of the interval, Cell2 will avoid during the time interval of the measurement interval: sending duplicate unnecessary data to the UE and avoiding deleting the UE's link configuration at Cell2.

Optionally, the notification information in step 502 may include: the unique identification information of the UE; the period and length of the measurement interval.

It should be noted that the

above steps

501 and 502 may be performed simultaneously.
