Claim:
1. A method for determining a position of a UE, the method comprising: a first network node receiving a request for positioning information about the UE; the first network node requesting a first positioning procedure at a first location node; the first location node determining using the first positioning procedure that involvement by a second location node is needed; the first location node initiating a trigger for positioning information about the UE to be sent to the second location node, wherein the first and second location nodes comprise first and second serving mobile location centers (SMLCs), respectively; the second location node, upon receiving the trigger for positioning information and determining the presence of an environment measurement parameter in said request, determining the position information of the UE by performing a second positioning procedure that the first SMLC does not support, based on the environment measurement parameter, and sending a position calculation response with the positioning information, wherein the second location node performing the second positioning procedure based on the environment measurement parameter comprises performing a finger printing positioning method that the second SMLC supports and the first SMLC does not support, using measurement data of path loss or signal strength.
