Abstract

Embodiments of the present disclosure provide a paging method, a device, and a system, and relate to the communications field, so as to reduce signaling exchange performed when an access network device pages UE, save a network resource, and improve data transmission efficiency. The paging method includes: receiving, by user equipment (UE), paging information sent by an access network device, where the paging information is used to instruct the UE to send a paging response by using an uplink data sending resource; and obtaining, by the UE, the uplink data sending resource according to the paging information, and sending paging response information to the access network device by using the uplink data sending resource.

Claims

1. A paging method, comprising:

receiving, by user equipment (UE), an unscheduled uplink data sending resource or a shared uplink data sending resource from an access network device by a broadcast information;

after receiving the unscheduled or a shared uplink data sending resource, receiving, by the UE, paging information from the access network device, wherein the paging information is used to instruct the UE to send a paging response information to the access network device by using the unscheduled or shared uplink data sending resource;

selecting, by the UE, an uplink data sending resource from the unscheduled or shared uplink data sending resource; and

sending, by the UE, paging response information to the access network device by using the selected uplink data sending resource.

2. The paging method according to claim 1, wherein the paging response information comprises a higher layer identifier of the UE, and the higher layer identifier of the UE is any one or more of a system architecture evolution-temporary mobile subscriber identity (S-TMSI), a mobility management entity-temporary mobile subscriber identity (M-TMSI), an international mobile subscriber identity (IMSI), or an internet protocol (IP) address of the UE.

3. The paging method according to claim 1, wherein the paging information comprises first information, the first information comprises a radio network temporary identifier (RNTI) and a higher layer identifier of the UE, and the higher layer identifier of the UE is any one or more of an S-TMSI, an M-TMSI, an IMSI, or an IP address of the UE.

4. The paging method according to claim 1, wherein selecting an uplink data sending resource from the unscheduled or shared uplink data sending resource, comprising:

selecting an uplink data sending resource according to a modulation and coding scheme, a transport block size, uplink load information, an uplink conflict probability, or air interface quality from the unscheduled or shared uplink data sending resource;

or

selecting randomly an uplink data sending resource from the unscheduled or shared uplink data sending resource.

5. A user equipment (UE), comprising:

a receiver, configured to;

receive an unscheduled uplink data sending resource or a shared uplink data sending resource from an access network device by a broadcast information, and

after receiving the unscheduled or shared uplink data sending resource, receive paging information from the access network device, wherein the paging information is used to instruct the UE to send a paging response information to the access network device by using the unscheduled or shared uplink data sending resource;

a processor, configured to;

select an uplink data sending resource from the unscheduled or shared uplink data sending resource; and

a transmitter, configured to, send paging response information to the access network device by using the selected uplink data sending resource.

6. The user equipment according to claim 5, wherein the paging response information comprises a higher layer identifier of the UE, and the higher layer identifier of the UE is any one or more of a system architecture evolution-temporary mobile subscriber identity (S-TMSI), a mobility management entity-temporary mobile subscriber identity (M-TMSI), an international mobile subscriber identity (IMSI), or an internet protocol (IP) address of the UE.

7. The user equipment according to claim 5, wherein the paging information comprises first information, the first information comprises a radio network temporary identifier (RNTI) and a higher layer identifier of the UE, and the higher layer identifier of the UE is any one or more of an S-TMSI, an M-TMSI, an IMSI, or an IP address of the UE.

8. The user equipment according to claim 7, wherein the RNTI is allocated by the access network device to the UE, and the RNTI and the higher layer identifier of the UE are in a mapping relationship.

9. The user equipment according to claim 7, wherein the paging response information comprises at least one of the RNTI and the higher layer identifier of the UE.

10. The user equipment according to claim 5, wherein the paging information comprises dedicated access preamble sequence information, the dedicated access preamble sequence information comprises dedicated access preamble sequence code and a higher layer identifier of the UE, and the higher layer identifier of the UE is any one or more of an S-TMSI, an M-TMSI, an IMSI, or an IP address of the UE.

11. The user equipment according to claim 10, wherein the paging response information comprises at least one of the dedicated access preamble sequence code and the higher layer identifier of the UE.

12. The user equipment according to claim 5, wherein selecting an uplink data sending resource from the unscheduled or shared uplink data sending resource, comprising:

selecting an uplink data sending resource according to a modulation and coding scheme, a transport block size, uplink load information, an uplink conflict probability, or air interface quality from the unscheduled or shared uplink data sending resource;

or

selecting randomly an uplink data sending resource from the unscheduled or shared uplink data sending resource.

13. An access network device, comprising:

a transmitter, configured to;

send an unscheduled uplink data sending resource or a shared uplink data sending resource to user equipment (UE) by a broadcast information, and

after sending the unscheduled or shared uplink data sending resource, send paging information to the UE, wherein the paging information is used to instruct the UE to send a paging response information to the access network device by using the unscheduled or shared uplink data sending resource; and

a receiver, configured to receive paging response information from the UE by using the unscheduled or shared uplink data sending resource.

14. The access network device according to claim 13, wherein the paging response information comprises a higher layer identifier of the UE, and the higher layer identifier of the UE is any one or more of a system architecture evolution-temporary mobile subscriber identity (S-TMSI), a mobility management entity-temporary mobile subscriber identity (M-TMSI), an international mobile subscriber identity (IMSI), or an internet protocol (IP) address of the UE.

15. The access network device according to claim 13, wherein the paging information comprises first information, the first information comprises a radio network temporary identifier (RNTI) and a higher layer identifier of the UE, and the higher layer identifier of the UE is any one or more of an S-TMSI, an M-TMSI, an IMSI, or an IP address of the UE.
