Abstract

The present disclosure relates to information transmission methods. One example method includes obtaining, by a positioning center, coverage indication information, where the coverage indication information is used to indicate a coverage enhancement level of user equipment UE, indicate that UE is at a first coverage enhancement level, or to indicate that UE requests to reduce a quantity of to-be-measured cells, and sending, by the positioning center, positioning measurement configuration information to the UE, where the positioning measurement configuration information is determined by the positioning center based on the coverage indication information, and the positioning measurement configuration information is used to perform positioning measurement configuration on the UE.

First claim

What is claimed is:

1. An information transmission method, comprising:
obtaining, by a positioning center, coverage indication information, wherein the coverage indication information indicates that a user equipment (UE) is at a coverage enhancement level;
in response to the coverage indication information indicating that the UE is at the coverage enhancement level, determining, by the positioning center according to the coverage indication information, positioning measurement configuration information, wherein the positioning measurement configuration information comprises a quantity of to-be-measured cells, and wherein the quantity of to-be-measured cells is used to limit a maximum quantity of to-be-measured cells; and
sending, by the positioning center, the positioning measurement configuration information to the UE, wherein the positioning measurement configuration information is used to perform positioning measurement configuration on the UE.

2. The method according to claim 1 , wherein the obtaining, by a positioning center, coverage indication information comprises:
receiving, by the positioning center, the coverage indication information from a core network device.

3. The method according to claim 2 , wherein the receiving, by the positioning center, coverage indication information from the core network device comprises:
receiving, by the positioning center, a location service request message from the core network device, wherein the location service request message comprises the coverage indication information.

4. The method according to claim 1 , wherein the positioning measurement configuration information comprises the following information about the UE:
to-be-measured frequency information.

5. The method according to claim 1 , wherein the coverage enhancement level is higher than a pre-determined coverage enhancement level.

6. An information transmission method, comprising:
receiving, by a core network device, coverage indication information from a base station, wherein the coverage indication information indicates that a user equipment (UE) is at a coverage enhancement level;
in response to the coverage indication information indicating that the UE is at the coverage enhancement level, sending, by the core network device, the coverage indication information to a positioning center;
obtaining, by the positioning center, the coverage indication information;
determining, by the positioning center according to the coverage indication information, positioning measurement configuration information, wherein the positioning measurement configuration information comprises a quantity of to-be-measured cells, and wherein the quantity of to-be-measured cells is used to limit a maximum quantity of to-be-measured cells; and
sending, by the positioning center, the positioning measurement configuration information to the UE, wherein the positioning measurement configuration information is used to perform positioning measurement configuration on the UE.

7. The method according to claim 6 , wherein the receiving, by a core network device, coverage indication information from a base station comprises:
receiving, by the core network device, an initial UE message or a UE context resume request message from the base station, wherein the initial UE message or the UE context resume request message comprises the coverage indication information.

8. The method according to claim 6 , wherein the sending, by the core network device, the coverage indication information to a positioning center comprises:
sending, by the core network device, a location service request message to the positioning center, wherein the location service request message comprises the coverage indication information.

9. The method according to claim 6 , wherein the positioning measurement configuration information comprises the following information about the UE:
to-be-measured frequency information.

10. A positioning center, comprising:
at least one processor, the at least one processor configured to obtain coverage indication information, wherein the coverage indication information indicates that a user equipment (UE) is at a coverage enhancement level;
the at least one processor further configured to determine, according to the coverage indication information indicating that the UE is at the coverage enhancement level, positioning measurement configuration information, wherein the positioning measurement configuration information comprises a quantity of to-be-measured cells, and wherein the quantity of to-be-measured cells is used to limit a maximum quantity of to-be-measured cells; and
a transmitter, the transmitter configured to send the positioning measurement configuration information to the UE, wherein the positioning measurement configuration information is used to perform positioning measurement configuration on the UE.

11. The positioning center according to claim 10 , wherein the positioning center further comprises:
a receiver, the receiver configured to receive the coverage indication information from a core network device.

12. The positioning center according to claim 11 , wherein the receiver is configured to:
receive a location service request message from the core network device, wherein the location service request message comprises the coverage indication information.

13. The positioning center according to claim 10 , wherein the coverage enhancement level is higher than a pre-determined coverage enhancement level.

14. The positioning center according to claim 10 , wherein the positioning measurement configuration information comprises the following information about the UE:
to-be-measured frequency information.

15. A system for information transmission, comprising a core network device and a positioning center, wherein:
the core network device is configured to:
receive coverage indication information from a base station, wherein the coverage indication information indicates that a user equipment (UE) is at a coverage enhancement level; and
in response to the coverage indication information indicating that the UE is at the coverage enhancement level, send the coverage indication information to the positioning center; and

the positioning center is configured to:
obtain the coverage indication information;
determine positioning measurement configuration information according to the coverage indication information, wherein the positioning measurement configuration information comprises a quantity of to-be-measured cells, and wherein the quantity of to-be-measured cells is used to limit a maximum quantity of to-be-measured cells; and
send the positioning measurement configuration information to the UE, wherein the positioning measurement configuration information is used to perform positioning measurement configuration on the UE.

16. The system according to claim 15 , wherein the core network device is configured to:
receive an initial UE message or a UE context resume request message sent by the base station, wherein the initial UE message or the UE context resume request message comprises the coverage indication information.

17. The system according to claim 15 , wherein the core network device is configured to:
send a location service request message to the positioning center, wherein the location service request message comprises the coverage indication information.

18. The system according to claim 15 , wherein the positioning measurement configuration information comprises the following information about the UE:
