Locating method in multi-connectivity network, terminal device and location management function entity

A method for positioning a terminal device in a multi-connectivity network, the method comprising:

• determining, by the terminal device, the position of the terminal device using a first radio access technology (RAT);
• and
• sending, by the terminal device, a locating message of the terminal device to a location management function entity through signaling over an air interface using a second RAT,
• wherein the locating message of the terminal device comprises:
• a first locating parameter of a cell of a first node, the first node corresponding to the first RAT;
• and
• a second locating parameter of a cell of a second node, the second node corresponding to the second RAT.

A location management function entity, comprising:

• a processor;
• and
• a memory connected to the processor and storing instructions, wherein the processor, when executing the instructions, is configured to:
• receive a locating message of a terminal device sent from the terminal device through signaling over an air interface using a second radio access technology (RAT);
• and
• locate the terminal device according to the locating message,
• wherein the locating message comprises:
• a first locating parameter of a cell of a first node, the first node corresponding to a first RAT;
• and
• a second locating parameter of a cell of a second node, the second node corresponding to the second RAT.
