Abstract

The present invention discloses a paging method, a device, and a paging system, and relates to the field of wireless communications technologies. The method provided in the present invention includes: receiving, by a base station, a paging message of machine-to-machine user equipment; calculating a paging location of the user equipment; determining a coverage level of the user equipment; and sending an air interface paging message to the user equipment according to the coverage level of the user equipment, and sending, in the paging location, paging scheduling information, where the paging scheduling information is used to indicate a location in which the air interface paging message is sent, and the air interface paging message includes the paging message of the user equipment.

First claim

What is claimed is:

1. A communication system, comprising a base station and a user equipment, wherein:
the base station is configured to receive a paging message of the user equipment;
the base station is further configured to determine a coverage level of the user equipment;
the base station is further configured to send an air interface paging message to the user equipment according to the coverage level of the user equipment, wherein the air interface paging message comprises the paging message, and the coverage level indicates a network coverage intensity of a location in which the user equipment is located;
the base station is further configured to receive indication information that is used to instruct to re-send the paging message; and
the base station is further configured to re-determine the coverage level of the user equipment; and to re-send the paging message to the user equipment according to the re-determined coverage level.

2. The communication system according to claim 1 , wherein:
the paging message is from a core work device, wherein the core network device is a mobility management entity (MME) or a serving general packet radio service support node (SGSN).

3. The communication system according to claim 1 , wherein the base station is further configured to determine a paging location of the user equipment according to the user identity of the user equipment comprises:
determining, by the base station, according to a paging cycle of a network configuration, a paging super frame density, and an equipment identity of the user equipment, a paging super frame in which the paging location is located; and
determining, by the base station, according to a quantity of paging occasions within one paging super frame, the equipment identity of the user equipment, and the paging super frame density, a paging occasion on which the paging location is located.

4. The communication system according to claim 1 ,
wherein the paging message of the user equipment comprises a user identity of the user equipment; and
the base station is further configured to determine a paging location of the user equipment according to the user identity;
the base station is further configured to send, in the paging location, paging scheduling information, wherein the paging scheduling information indicates a location in which the air interface paging message is sent.

5. The communication system according to claim 1 , wherein:
the indication information is from a core work device, wherein the core network device is a MME or a SGSN.

6. A communication system, comprising a base station and a core network device, wherein:
the core network device is configured to send a paging message of a user equipment to the base station;
the base station is configured to receive the paging message;
the base station is further configured to determine a coverage level of the user equipment;
the base station is further configured to send an air interface paging message to the user equipment according to the coverage level of the user equipment, wherein the air interface paging message comprises the paging message, and the coverage level indicates a network coverage intensity of a location in which the user equipment is located;
the core network device is further configured to send indication information to the base station, wherein the indication information is used to instruct the base station to re-send the paging message;
the base station is further configured to re-determine the coverage level of the user equipment; and re-send the paging message to the user equipment according to the re-determined coverage level.

7. The communication system according to claim 6 , wherein:
the core network device is a mobility management entity (MME) or a serving general packet radio service support node (SGSN).

8. The communication system according to claim 6 , wherein:
the paging message comprises a user identity of the user equipment.

9. The communication system according to claim 6 , further comprises:
the base station is further configured to determine a paging location of the user equipment according to the user identity of the user equipment; and
the base station is further configured to send, in the paging location, paging scheduling information, wherein the paging scheduling information is used to indicate a location in which the air interface paging message is sent.

10. A communication method, wherein the method comprises:
sending, by a core network device, a paging message of a user equipment to the base station;
receiving, by a base station, the paging message;
determining, by a base station, a coverage level of the user equipment;
sending, by the base station, an air interface paging message to the user equipment according to the coverage level of the user equipment, wherein the air interface paging message comprises the paging message, and the coverage level indicates a network coverage intensity of a location in which the user equipment is located;
sending, by the core network device, indication information to the base station, wherein the indication information is used to instruct the base station to re-send the paging message;
re-determining, by the base station, the coverage level of the user equipment; and
re-sending, by the base station, the paging message to the user equipment according to the re-determined coverage level.

11. The communication method according to claim 10 , wherein:
the core network device is a mobility management entity (MME) or a serving general packet radio service support node (SGSN).

12. The communication method according to claim 10 , wherein:
the paging message comprises a user identity of the user equipment.

13. The communication method according to claim 10 , further comprises:
determining, by the base station, a paging location of the user equipment according to the user identity of the user equipment; and
sending, by the base station, in the paging location, paging scheduling information, wherein the paging scheduling information is used to indicate a location in which the air interface paging message is sent.
