1. A user equipment positioning method, comprising:
- while positioning measurement of a user equipment (UE) and when the UE needs to be handed over from a source node to a target node, receiving, by the target node, user identification information of the UE, wherein the user identification information is used for uniquely identifying the UE;
sending, by the target node, an indication of not notifying a positioning server to a mobility management entity (MME), wherein the indication of not notifying a positioning server is used to instruct the MME to cancel informing the positioning server that the UE has been handed over;
after the UE is handed over to the target node, performing, by the target node, positioning measurement on the UE according to the user identification information; and
reporting obtained positioning measurement data and the user identification information to the positioning server.

9. A user equipment positioning method, comprising:
-
during positioning measurement of a user equipment (UE) and when the UE needs to be handed over from a source node to a target node, receiving, by the source node, an A3 measurement report sent by the UE, wherein the A3 measurement report is used by the UE to request a handover from the source node; and sending, by the source node, user identification information of the UE to the target node, so that the target node performs positioning measurement on the UE after the UE is handed over to the target node, wherein the user identification information is used for uniquely identifying the UE. - View Dependent Claims (10, 11, 12, 13)

14. A user equipment positioning method, comprising:
-
while positioning measurement of a user equipment (UE) and when the UE needs to be handed over from a source node to a target node, receiving, by the target node through an X2 interface, user identification information and/or a positioning measurement ID sent by the source node;
or receiving through, by the target node an S1 interface, the user identification information and/or the positioning measurement ID sent by a mobility management entity (MME);wherein the user identification information comprises at least one type of the following information;
a long term evolution positioning protocol type-A transaction ID (LPPa Transaction ID), an evolved serving mobile location center measurement ID (E-SMLC UE Measurement ID), and an evolved base station user end measurement ID (eNB UE Measurement ID); andwherein the positioning measurement ID is an enhanced cell ID positioning method (E-CID) identifier.

15. A user equipment positioning method, comprising:
-
while positioning measurement of a user equipment (UE) and when the UE needs to be handed over from a source node to a target node, sending, by the source node through an X2 interface, user identification information and/or a positioning measurement ID to the target node; or sending, by the source node through an S1 interface, the user identification information and/or the positioning measurement ID to a mobility management entity (MME), so that the MME sends the user identification information and/or the positioning measurement ID to the target node through an S1 interface; wherein the user identification information comprises at least one type of the following information;
a long term evolution positioning protocol type-A transaction ID (LPPa Transaction ID), an evolved serving mobile location center measurement ID (E-SMLC UE Measurement ID), and an evolved base station user end measurement ID (eNB UE Measurement ID); andwherein the positioning measurement ID is an enhanced cell ID positioning method (E-CID) identifier.

16. A user equipment positioning method, comprising:
while positioning measurement of a user equipment (UE) and after the UE is handed over from a source node to a target node, sending, by the target node, an indication of not notifying a positioning server to a mobility management entity (MME), wherein indication of not notifying a positioning server is used for instructing the MME to cancel informing the positioning server that the UE has been handed over, wherein indication of not notifying a positioning server is a continuous positioning indication or an indication of not triggering new positioning.

17. A base station comprising:
-
a receiver, configured to, while positioning measurement of a user equipment (UE) and when the UE needs to be handed over from the base station to a target base station, receive an A3 measurement report sent by the UE, wherein the A3 measurement report is used by the UE to request a handover from the base station, wherein the base station is source base station; and a transmitter, configured to send user identification information of the UE to the target base station, so that the target base station performs positioning measurement on the UE after the UE is handed over to the target base station, wherein the user identification information is used for uniquely identifying the UE. - View Dependent Claims (18, 19, 20, 21)
