Abstract:
1. A region access platform, comprising: a processor; and a storage device storing computer executable instructions that when executed by the processor cause the processor to perform the steps of: receiving a positioning request from a positioning client, and authenticating the positioning client, when the authentication is passed, determining the type of the positioning; when the type of the positioning is a coarse positioning, obtaining a positioning result by querying a local base station database, wherein the local base station database comprises location information of all the base stations within the service area of the region access platform; when the type of the positioning is a high-precision positioning, obtaining a positioning result from a mobile positioning center; and returning the positioning result to the positioning client; wherein, said storage device further stores computer executable instructions that when executed by the processor cause the processor to perform the steps of: sending a notification message to a to-be-positioned terminal, querying whether the positioning is allowed or not after a positioning allowed acknowledgement message returned by the to-be-positioned terminal is received, obtaining the positioning result, if no positioning allowed acknowledgement message returned by the positioned terminal is received, returning a failure message to said positioning client.
