Description
Technical field
The present invention relates to field of locating technology more particularly to a kind of method and system of network positions, mobile terminal and net
Network side apparatus.
Background technique
Currently, universal with the arrival of mobile internet era and mobile terminal (such as smart phone), user passes through shifting
The application that dynamic terminal positions the geographical location that itself is presently in is also more and more extensive.Current network locating method master
It is accomplished by user and Location Request is sent to network side by mobile terminal；The Location Request that network side is sent according to user
The location information of corresponding position is obtained, and the location information that will acquire returns to the mobile terminal.
Although existing network locating method simple, easily can position user's present position,
There are following technological deficiencies:
(1) in the actual environment, the positioning of user's success depends greatly on the connection state of mobile network, when out
When the problems such as existing mobile network is covered with blind area, mobile terminal fault, when breaking when the mobile network of user position will appear
The problems such as continuous unstable state, this will result directly in positioning failure or abnormal positioning result；
(2) network positions mode uses individual requests mode at present, i.e., user is only to determining present position
Position directly sends Location Request to network side by mobile terminal；But for some user, the scope of activities of user,
Region is comparatively relatively fixed, has certain Regional Characteristics, therefore, user is possible to section in different times can be to same
One position sends Location Request to network side；Since number of users of mobile terminal amount is more huge, if each user is all made of
Foregoing manner is positioned, and not only brings biggish burden to network side, but also is sent Location Request and received location information
It requires through network side, time delay is larger, and efficiency is lower.

In the embodiment of the present invention, in the corresponding relationship that basis on location and location information is locally stored of mobile terminal, use
Family generates basis on location according to the positioning signal information of mobile terminal when needing to position the position being presently in,
And corresponding location information is preferentially searched from the corresponding relationship being locally stored according to basis on location, if search less than again to
Network side sends Location Request, to obtain location information from network side.Using technical solution of the present invention, on the one hand, deposited locally
The corresponding relationship for containing basis on location and location information, when needing to position current location, preferentially locally search with
The corresponding location information of basis on location, is locally-located and does not need through network layer, and time delay is lower, relative to pass through network side positioning
For, technical solution of the present invention not only increases location efficiency, and simplifies the process of positioning, more convenient；On the other hand, needle
The case where section carries out resetting to the same position in different times to user, it is only necessary to carry out primary network side positioning i.e.
Can, it is subsequent to be positioned from local, it does not need to position every time as the prior art to require to position to network side transmission and ask
It asks to carry out subsequent positioning operation, therefore, reduces what user was positioned by network side using technical solution of the present invention
Frequency reduces the workload of network side；In another aspect, periodically being carried out more to the expired location information being locally stored
When newly, or in network side having updating location information, prompting mobile terminal is updated local corresponding location information, because
This, can timely be updated the location information being locally stored using technical solution of the present invention, further ensure that local deposit
The accuracy for storing up location information, to improve the accuracy of positioning.
