A method, performed by a Location Sever, LS, of supporting location services and positioning, comprising: receiving a location request for a UE from a Mobility Management Entity, MME, at the LS via an interface between the MME and the LS; determining a positioning method and a corresponding positioning procedure to use; performing the positioning procedure between the LS and the UE in response to the location request, wherein performing the positioning procedure includes: sending a first positioning message from the LS to the MME for forwarding to the UE, via the eNB, wherein the first positioning message is a LTE Positioning Protocol, LPP, downlink positioning message for forwarding to the UE to request location information from the UE, wherein the first positioning message is encapsulated in a location services Application Protocol, LCS-AP, positioning request message, wherein the LCS-AP protocol is a lower layer protocol than LPP; and receiving, at the LS, a second positioning message including the requested location information, the second positioning message sent by the UE to the MME via the eNB, and forwarded by the MME, wherein the second positioning message is an uplink positioning message sent by the UE, wherein the second positioning message is a LPP uplink positioning message encapsulated in a LCS-AP positioning response message; determining, by the LS, a location estimate for the UE based on the location information; and sending a location response, containing the location estimate for the UE, from the LS to the MME after the positioning procedure via the interface between the MME and the LS, wherein the location response comprises information indicating the positioning method used to obtain the location estimate. receiving a location request for a UE from a Mobility Management Entity, MME, at the LS via an interface between the MME and the LS; determining a positioning method and a corresponding positioning procedure to use; performing the positioning procedure between the LS and the UE in response to the location request, wherein performing the positioning procedure includes: sending a first positioning message from the LS to the MME for forwarding to the UE, via the eNB, wherein the first positioning message is a LTE Positioning Protocol, LPP, downlink positioning message for forwarding to the UE to request location information from the UE, wherein the first positioning message is encapsulated in a location services Application Protocol, LCS-AP, positioning request message, wherein the LCS-AP protocol is a lower layer protocol than LPP; and receiving, at the LS, a second positioning message including the requested location information, the second positioning message sent by the UE to the MME via the eNB, and forwarded by the MME, wherein the second positioning message is an uplink positioning message sent by the UE, wherein the second positioning message is a LPP uplink positioning message encapsulated in a LCS-AP positioning response message; determining, by the LS, a location estimate for the UE based on the location information; and sending a first positioning message from the LS to the MME for forwarding to the UE, via the eNB, wherein the first positioning message is a LTE Positioning Protocol, LPP, downlink positioning message for forwarding to the UE to request location information from the UE, wherein the first positioning message is encapsulated in a location services Application Protocol, LCS-AP, positioning request message, wherein the LCS-AP protocol is a lower layer protocol than LPP; and receiving, at the LS, a second positioning message including the requested location information, the second positioning message sent by the UE to the MME via the eNB, and forwarded by the MME, wherein the second positioning message is an uplink positioning message sent by the UE, wherein the second positioning message is a LPP uplink positioning message encapsulated in a LCS-AP positioning response message; determining, by the LS, a location estimate for the UE based on the location information; and sending a location response, containing the location estimate for the UE, from the LS to the MME after the positioning procedure via the interface between the MME and the LS, wherein the location response comprises information indicating the positioning method used to obtain the location estimate.
