Ratio, the cellular network of rate intensity are successfully accessed rate and satellite network is successfully accessed the ratio of rate；
Current longitude and latitude and signal measurement data are sent to business by dedicated control channel and put down by step S204, terminal
Platform.
For example, latitude and longitude information is associated with the various measured values of MDT after UE is reported, completed in TCE based on timestamp.
TCE distinguishes MDT according to measurement ID, encapsulates MDT reporting message according to the parameter of UE node, packaged data packet is issued business
Platform.Business platform can carry out the self study of course line blind area according to signal measurement data, calculate the confidence level of current longitude and latitude,
Course line blind area table is periodically issued to UE after updating confidence level and is saved.
Optionally, terminal sends message informing to business platform, to notify business platform to extract measuring signal number from terminal
According to.
For example, being improved to data back mechanism in MDT, message informing and measurement data are uploaded and separated, no longer in fact
Shi Huichuan measurement data, but be ' 1 ' by the highest order that message is replied in setting, inform that platform takes measurement data at one's leisure.
According to acquisition data correction using longitude and latitude confidence level as the course line blind area table of index.And it is periodically issued in the form of firmware update
The dual-mode terminal in the course line.
Step S206, business platform obtain the confidence level of current longitude and latitude using signal measurement data.
For example, each ratio data in signal measurement data can be weighted and averaged by business platform, thus to every
Multiple measured values of a longitude and latitude carry out Decision fusion,.
In above-described embodiment, for satellite network-cellular network dual-mode terminal Yu Haiyang, the Changjiang river etc. scene, due to
Transportation route is substantially stationary, the signal coverage condition somewhat constant on course line, therefore can realize course line blind area signal self study side
