The information that calculates simultaneously is sent out.
If likewise, the FBS204 and FBS205 in Fig. 3 due to the signal of macro base station that receives all
It is undesirable, may select using relative macro base station confidence level relatively low FBS201, FBS202 and
The positional information that FBS203 is sent is calculating the position coordinateses and confidence level of this website.In this case,
The positional information of website is to come from other in whole or in part to obtain by the technical scheme that the present invention is provided
Position little base station, therefore the confidence level of calculated positional information will less than all according to pass through defend
The situation that star navigation system determines the position of itself website to calculate.
Further, after website calculates the positional information and confidence level of this website, can locally preserve
These information.Subsequently, when the method shown in Fig. 1 of the present invention is performed again, can putting current calculating
Reliability is contrasted with the confidence level of the history for preserving before, is gone through when current calculated confidence level is more than
During history value, the positional information and confidence calculated during the method shown in this execution Fig. 1 of the present invention can be adopted
The information that degree is preserved before updating.Such as：FBS205 is counted by FBS201, FBS202 and FBS203
Calculate and obtain the positional information and confidence level of this website, and locally saving these information.But, subsequently
When the effective information for receiving outdoor macro base station BS204 and after calculate positional information confidence level, it is clear that this
When positional information confidence level when being above the history value for preserving before, this is, it is necessary to will currently pass through
Position coordinateses and put that the positional information obtained according to the broadcast message of BS204 and confidence level replacement have been preserved
Reliability, and this new information is sent out.
It should be noted that the UE201 in Fig. 3 is the mobile terminal being placed in heterogeneous wireless network, move
Dynamic terminal also can be by the positional information that the little base stations of several FBS in network send, by the present invention
The technical scheme of offer determines the positional information of itself to calculate.
