Through the SUPL protocol, the location information of the SET terminal can be obtained.
As shown in fig. 2, SUPL pos messages are used for assisted location data transfer in an actively network initiated location session, where a SUPL agent may be located on the target terminal or on the network side. The detailed process is as follows:
