  • unnecessary switching may refer to: the terminal switches from a first radio access technology (Radio Access Technology, RAT) to a second RAT, and within a period of time thereafter, the UE detects that the signal quality of the first RAT can still meet the requirements of the service received by the current user, then the UE's switching from the first RAT to the second RAT is considered to be an unnecessary switching (premature inter-system HO without connection failure).
  • RAT Radio Access Technology
  • this may be caused by setting the serving cell threshold for triggering handover in the source system too high. If the serving cell threshold (e.g., NR cell) is set too high, and a cell with good signal strength is available in another system (e.g., EPS (Evolved Packet System)), handover to the other system may be triggered unnecessarily, resulting in inefficient network usage.

If an inter-system handover from EPS to 5GS is performed within the specified measurement period, the measurement period expires. In this case, the eNB in the EPS may send a HO report. If no NR cell can be included, or if the specified time period is interrupted by an inter-system handover to a system other than 5GS, the HO report shall not be sent.
  • a radio coverage and/or quality threshold radio thresholds RSRP, RSRQ, and/or SINR
  • the RAN node in the source system can decide whether/how to adjust its parameters (e.g., adjust the threshold for triggering inter-system HO).
  • non-essential handovers can also occur between two intra-RAT base stations.
  • the inter-RAT scenario is more interesting for at least one of the following reasons:
  • the switching cost between different RATs is higher: Cross-RAT switching (for example, switching from LTE to NR or vice versa)
  • Handovers within the same RAT e.g., LTE to LTE
  • Handovers within the same RAT are generally more complex than handovers within the same RAT (e.g., LTE to LTE), requiring more signaling and potentially resulting in longer service interruptions.
  • Inter-RAT coordination issues Networks between different RATs may be managed by different network operators, or even by the same operator, their deployment and optimization strategies may differ. This may lead to inconsistent network performance at the edge and increase the risk of ping-pong effects.
  • Inter-RAT handover may have a greater negative impact on user experience because it may involve different network performance characteristics (e.g., speed, latency, etc.) and changes in quality of service (QoS).
