Abstract

Embodiments of the present disclosure provide a method and an apparatus for paging a user equipment. A paging message sent by an MME is received, where the foregoing paging message includes indication information of a UE type; a scheduling resource for sending a paging message of the foregoing UE type is determined according to the indication information of the UE type; and the paging message of the foregoing UE is sent on the scheduling resource, thereby reducing impact on a conventional type of UE that is caused by a limitation on a bandwidth of a received signal of a special type of UE.

Claims

1. A method for paging a user equipment, comprising:

receiving at least one first paging message sent by a mobility management entity MME, wherein the first paging message carries an identifier of a to-be-paged user equipment UE and coverage enhancement requirement information of the to-be-paged UE;

grouping the to-be-paged UE in the at least one first paging message into at least one group according to the coverage enhancement requirement information in the at least one first paging message;

determining, for each of the group according to coverage enhancement requirement information of a to-be-paged UE in the group, a first quantity of repeated sending times for sending a second paging message to the UE in the group, wherein the second paging message carries an identifier of the to-be-paged UE in the group; and

sending the second paging message according to the first quantity of repeated sending times.

2. The method according to claim 1, wherein the coverage enhancement requirement information of the to-be-paged UE is a coverage enhancement level, a coverage enhancement value, or a second quantity of repeated sending times that is of the to-be-paged UE;

and

the determining, according to coverage enhancement requirement information of a to-be-paged UE in the group, a first quantity of repeated sending times for sending a second paging message to the UE in the group comprises;

determining, according to a maximum coverage enhancement level, a maximum coverage enhancement value, or a maximum second quantity of repeated sending times that is of the to-be-paged UE in the group, the first quantity of repeated sending times for sending the second paging message to the to-be-paged UE in the group.

3. The method according to claim 1, wherein the second paging message further comprises dedicated access resource information, so that the to-be-paged UE accesses a network according to the dedicated access resource information.

4. An apparatus for paging a user equipment, comprising:

a receiver, configured to receive at least one first paging message sent by a mobility management entity MME, wherein the first paging message carries an identifier of a to-be-paged user equipment UE and coverage enhancement requirement information of the to-be-paged UE;

a processor, configured to;

group the to-be-paged UE in the at least one first paging message into at least one group according to the coverage enhancement requirement information in the at least one first paging message; and

determine, for each of the group according to coverage enhancement requirement information of a to-be-paged UE in the group, a first quantity of repeated sending times for sending a second paging message to the UE in the group, wherein the second paging message carries an identifier of the to-be-paged UE in the group; and

a transmitter, configured to send the second paging message according to the first quantity of repeated sending times.

5. The apparatus according to claim 4, wherein the coverage enhancement requirement information of the to-be-paged UE is a coverage enhancement level, a coverage enhancement value, or a second quantity of repeated sending times that is of the to-be-paged UE;

and

the processor is configured to determine, according to a maximum coverage enhancement level, a maximum coverage enhancement value, or a maximum second quantity of repeated sending times that is of the to-be-paged UE in the group, the first quantity of repeated sending times for sending the second paging message to the to-be-paged UE in the group.

6. The apparatus according to claim 4, wherein the second paging message further comprises dedicated access resource information, so that the to-be-paged UE in the second paging message accesses a network according to the dedicated access resource information.

7. An apparatus for paging a user equipment, comprising:

an acquirer, configured to acquire coverage enhancement requirement information of a to-be-paged user equipment UE; and

a transmitter, configured to send a first paging message to a base station, wherein the first paging message carries an identifier of the to-be-paged UE and the coverage enhancement requirement information of the to-be-paged UE.

8. The apparatus according to claim 7, wherein the acquirer is configured to receive the coverage enhancement requirement information reported by the to-be-paged UE by using non-access stratum NAS signaling, wherein the coverage enhancement requirement information is a coverage enhancement level, a coverage enhancement value, or a second quantity of repeated sending times.

9. The apparatus according to claim 7, wherein the acquirer is configured to receive the coverage enhancement requirement information of the to-be-paged UE that is reported by the base station, wherein the coverage enhancement requirement information is a coverage enhancement level, a coverage enhancement value, or a second quantity of repeated sending times.
