The alien frequencies signal of B1/B2 event thresholds distributes more time of measuring.
, such as there is the GSM/LTE alien frequencies signals for meeting B1/B2 events in step 4, and the triggered time meets,
Terminal can report B1/B2 events.
Step 5, if entering to GSM and LTE alien frequencies signal intensitys respectively without B1/B2 events are met
Row statistics, and prioritization is carried out by signal intensity.Signal intensity is stronger, and priority is higher.
The embodiment of the present invention is issued by the optimization to two critical workflow parts of isosystem measurement, i.e. network
Issue after B1/B2 events for GSM/LTE for the optimization of LTE different-frequency measures and network after A3/A4 events
Different-frequency measure optimizing scheduling, while measurement opportunity optimization is considered with preferential two combined factors of signal intensity,
It is capable of the alien frequencies information of quick reasonable positioning, so as to the measurement time needed for reducing significantly, improves
The different system handover success rates of eSRVCC.
