Abstract

Disclosed is a positioning method. The positioning method includes operations as follows. Multiple pieces of positioning information of various RATs are acquired, each pieces of positioning information among the multiple pieces of positioning information is determined by means of a corresponding RAT, and is representative of a position area of a terminal. Position information of the terminal is determined according to the multiple pieces of positioning information.

First claim

The invention claimed is:

1. A positioning method, executed by a terminal, the method comprising:
acquiring multiple pieces of positioning information of various Radio Access Technologies (RATs) which are non-satellite radio technologies, each piece of positioning information among the multiple pieces of positioning information being determined by means of a corresponding RAT, and being representative of a position area of a terminal; and
determining position information of the terminal according to the multiple pieces of positioning information,
wherein the various RATs comprise at least one primary RAT and at least one secondary RAT; and
wherein the determining the position information of the terminal according to the multiple pieces of positioning information comprises:
determining the position information of the terminal according to positioning information of the at least one primary RAT, and
wherein the method further comprises at least one of the following:
switching one or more primary RATs of the at least one primary RAT into secondary RATs;
or, switching one or more secondary RATs of the at least one secondary RAT into primary RATs,
wherein the method further comprises: before acquiring the multiple pieces of positioning information of various RATs,
sending, by the terminal, uplink data to base stations of the various RATs, so that the base stations of the various RATs determine the positioning information of the terminal according to the uplink data, wherein the uplink data carries information of time at which the terminal sends the uplink data,
wherein before determining position information of the terminal according to the multiple pieces of positioning information, the method further comprises:
receiving registration information sent by the base stations of the various RATs; and
determining the position information of the terminal according to the multiple pieces of positioning information comprises:
determining the position information of the terminal according to the registration information and the multiple pieces of positioning information,
wherein the registration information comprises:
position information of the base station, band information of the base station, transmitting power of the base station, and antenna configuration information of the base station;
wherein the determining the position information of the terminal according to the multiple pieces of positioning information comprises:
determining that first positioning information of a first RAT in the various RATs has a possibility of being inaccurate, determining the position information of the terminal according to other pieces of positioning information, which are those among the multiple pieces of positioning information other than the first positioning information.

2. The method according to claim 1 , wherein the registration information is sent by the base station in a broadcast message form, and the broadcast message is sent by the base station over dedicated signaling.

3. The method according to claim 2 , wherein the determining the position information of the terminal according to the multiple pieces of positioning information comprises:
determining the position information of the terminal according to the multiple pieces of positioning information in conjunction with positioning information acquired by a built-in sensor of the terminal.

4. The method according to claim 1 , wherein the positioning information further comprises time information corresponding to the position area; and
wherein the determining the position information of the terminal according to the multiple pieces of positioning information comprises:
determining the position information of the terminal and a movement trail of the terminal according to the multiple pieces of positioning information.

5. The method according to claim 1 , wherein the various RATs comprise a first type of RATs and a second type of RATs, wherein a positioning accuracy of the first type of RATs is lower than that of the second type of RATs; and
wherein the determining the position information of the terminal according to the multiple pieces of positioning information comprises:
determining a rough range of the terminal according to multiple pieces of positioning information of the first type of RATs; and
determining the position information of the terminal based on the rough range according to multiple pieces of positioning information of the second type of RATs,
wherein the first type of RATs are RATs supporting continuous coverage, and the second type of RATs are RATs deployed in a hotspot manner.

6. The method according to claim 1 , wherein the determining the position information of the terminal according to the other pieces of positioning information, which are those among the multiple pieces of positioning information other than the first positioning information comprises:
determining the position information of the terminal by using a weighted average of the other pieces of positioning information.

7. A positioning device, comprising:
a processor; and
a memory storing computer readable instructions executable by the processor,
wherein the processor is configured to:
acquire multiple pieces of positioning information of various Radio Access Technologies (RATs) which are non-satellite radio technologies, wherein each piece of positioning information among the multiple pieces of positioning information is determined by means of the corresponding RAT, and is representative of a position area of a terminal; and
determine position information of the terminal according to the multiple pieces of positioning information,
wherein the various RATs comprise at least one primary RAT and at least one secondary RAT; and
wherein the processor is specifically configured to determine the position information of the terminal according to positioning information of the at least one primary RAT,
wherein the processor is further configured to perform at least one of the following:
switch one or more primary RATs of the at least one primary RAT into secondary RATs;
or, switch one or more secondary RATs of the at least one secondary RAT into primary RATs,
wherein before acquiring the multiple pieces of positioning information of the various RATs, the processor is further configured to send uplink data to base stations of the various RATs, so that the base stations of the various RATs determine the positioning information of the terminal according to the uplink data, wherein the uplink data carries information of time at which the terminal sends the uplink data,
wherein the processor is configured to:
receive registration information sent by the base stations of the various RATs; and
determine the position information of the terminal according to the registration information and the multiple pieces of positioning information,
wherein the registration information comprises:
position information of the base station, band information of the base station, transmitting power of the base station, and antenna configuration information of the base station;
wherein the processor is configured to:
determine that first positioning information of a first RAT in the various RATs has a possibility of being inaccurate, determine the position information of the terminal according to a weighted average of other pieces of positioning information, which are those among the multiple pieces of positioning information other than the first positioning information.

8. The device according to claim 7 , wherein the device is the terminal, and the registration information is sent by the base station in a broadcast message form, and the broadcast message is sent by the base station over dedicated signaling.
