Abstract

Embodiments of the present invention provide a positioning measurement processing method and equipment for user equipment. The method includes: the second base station receives a handover request sent by the first base station, and the handover request includes an E-CID measurement association identifier and a UE identifier; after receiving the handover completion message of the UE, the second base station sends a message to the MME Sending a path switch request message, the path switch request message including the UE identity and an immediate trigger location request indication; wherein the immediate trigger location request indication is used to instruct the MME to immediately send a second location request to the E-SMLC message; the second base station receives the second E-CID measurement start request sent by the E-SMLC, and performs the E-CID measurement on the UE according to the second E-CID measurement start request; thereby realizing During UE handover, the E-CID positioning delay caused by re-triggering positioning measurement is reduced.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a positioning measurement processing method and device for user equipment. Background technique [0002] "Positioning" is a service for the network side to estimate accurate location information for User Equipment (UE) and is mainly used in some scenarios related to social security, such as: arresting criminals, guiding escape routes, etc. [0003] In the prior art, for the Enhanced Cell-ID (positioning method), referred to as: E-CID positioning method, from the perspective of the terminal side, the UE measures the downlink cell specific location of the serving cell. Reference Signals (Cell-specific Reference Signals, referred to as: CRS) to estimate the receiving moment of the UE (R X ), and estimate the transmission time of the UE side by sending the uplink Sounding Reference Signal (Sounding Reference Signal, SRS for short) by itself (T X ), so as to ca...
