- the terminal records a successful handover report
- the content of the successful handover report records the measurement information at the trigger time, cell identification information, terminal location information and timer value, etc.

- MRO Mobility Robustness Optimization
- the terminal will record the RLF report when handover failure or RLF occurs. After the handover fails, the terminal selects a cell, and then re-connects to the network through RRC connection re-establishment or RRC connection establishment, and notifies the network that the RLF report is reserved on the terminal side, and the network side obtains the RLF report from the terminal when necessary, for network Side network optimization.
- the MRO feature is mainly used to discover and solve parameter configuration problems in the mobility process, and defines three failure types, including handover too early, handover too late, and handover to the wrong cell. in:
- Premature handover During the handover process, the terminal fails to access the target cell, or the terminal successfully accesses the target cell but the radio link fails soon, and the terminal re-establishes the RRC connection and tries to access the source cell;
- the terminal fails to access the target cell, or the terminal successfully accesses the target cell but the radio link fails soon, and the terminal re-establishes an RRC connection and tries to access a cell different from the handover target cell and the source cell. other districts.
- the terminal After the handover is completed, whether the terminal can stably camp on the target cell is the key to judging the above failure type. If the UE has been camped on stably, it has nothing to do with the previous handover if the failure occurs again, because after the handover is completed, the UE can camp on the target cell stably. If it does not reside stably, it may be caused by the previous handover, for example, the selection of the target cell is unreasonable.
- the UE report timer in the RLF report To determine whether the terminal is camping stably, use the UE report timer in the RLF report to judge. If the value is relatively small, it means that the terminal is not camping stably. If it is relatively large, it means camping stably after handover. If it is 0, it means that no switching occurs.
- the DASP handover succeeds and the terminal can stably camp in the target cell, but the radio link failure occurs in the source cell during the DAPS handover process.
- the DAPS handover and access to the target cell succeeds, but the radio link fails soon, and the terminal re-establishes the RRC connection and tries to access the source cell.
- the terminal fails to access the target cell, but falls back to the source cell successfully and no RLF occurs for a period of time.
- RLF first occurs in the connection of the source cell, and then the terminal fails to access the target cell, and the terminal re-establishes the RRC connection and tries to access other cells different from the handover target cell and the source cell.
- the access to the target cell is successful, but the radio link fails soon, and the terminal re-establishes the RRC connection and tries to access other cells different from the handover target cell and the source cell.
- Radio link failure occurs in the source cell during the DAPS handover process, it will be recorded in the successful handover report. Subsequently, if the target side access fails or the target side random access succeeds but RLF occurs soon, it will be recorded in the RLF report.
- the message flow between network nodes includes a failure indication message, a handover report message, and an Access and mobility indication message.
- the UE may re-connect to the network after handover failure or RLF failure.
- the network node obtains the RLF report of the UE, if the current network node is not the node where the failure occurred, it needs to forward the RLF report and other related information to the failed network among network nodes. Nodes, which facilitate the analysis and optimization of failed network nodes.
- the failure indication message is triggered by an RRC re-establishment request or RRC establishment on the air interface.
- RRC re-establishment request optionally, include the information carried in the RRC re-establishment request and the UE RLF report; for the RRC establishment, include the UE RLF report.
- Step 1 the handover of UE from network node 1 to network node 2 is successful
- Step 2 a radio link failure RLF occurs on network node 2;
- Step 3 the UE records the RLF report
- Step 4 the UE successfully accesses the network node 3;
