Abstract

A paging method of the present invention is a paging method for paging a UE (10) in an idle state when a P-GW (20) receives a packet for the UE (10) and includes the steps of: in a S-GW (30), setting reception type information of the packet received by the P-GW (20) in “Downlink Data Notification” and sending the “Downlink Data Notification” to an MME (40) and an SGSN (60), and in the MME (40) and SGSN (60), determining whether or not to page the UE (10) based on the reception type information included in the “Downlink Data Notification” from the S-GW (30).

Claims

1. A paging method for paging a user terminal in an idle state when a first gateway apparatus receives a packet for the user terminal, the paging method comprising the steps of:

in a second gateway apparatus, setting reception type information of the packet received by the first gateway apparatus in a paging request signal, the reception type information including bearer information of a bearer to which the packet received by the first gateway apparatus is mapped, and sending the paging request signal to a core network apparatus; and

in the core network apparatus, determining whether or not to page the user terminal based on the reception type information included in the paging request signal from the second gateway apparatus.

2. The paging method according to claim 1, wherein in the step of determining whether or not to page the user terminal, the core network apparatus determines whether or not page the user terminal based on the reception type information included in the paging request signal and a congestion state of the core network apparatus.

3. The paging method according to claim 1, wherein the reception type information is set based on at least one of bearer identification information for identifying a bearer to send the packet and bearer QoS information indicating QoS of the bearer.

4. The paging method according to claim 1, wherein the reception type information includes the bearer identification information and the bearer QoS information.

14. The paging method according to claim 2, wherein the reception type information is set based on at least one of bearer identification information for identifying a bearer to send the packet and bearer QoS information indicating QoS of the bearer.

15. The paging method according to claim 2, wherein the reception type information includes the bearer identification information and the bearer QoS information.

5. A paging method for paging a user terminal in an idle state when a first gateway apparatus receives a packet for the user terminal, the paging method comprising the steps of:

in a second gateway apparatus, setting reception type information of the packet received by the first gateway apparatus in a paging request signal, the reception type information including bearer information of a bearer to which the packet received by the first gateway apparatus is mapped, and sending the paging request signal to a core network apparatus;

in the core network apparatus, setting paging information for paging the user terminal in a paging signal based on the reception type information included in the paging request signal from the second gateway apparatus, and sending the paging signal to a radio access network apparatus; and

in the radio access network apparatus, determining whether or not to page the user terminal based on the paging information included in the paging signal from the core network apparatus.

6. The paging method according to claim 5, wherein the reception type information is set based on at least one of bearer identification information for identifying a bearer to send the packet and bearer QoS information indicating QoS of the bearer.

7. The paging method according to claim 6, wherein the reception type information includes the bearer identification information and the bearer QoS information.

8. The paging method according to claim 6, wherein the paging information is set based on the bearer QoS information set as the reception type information.

16. The paging method according to claim 7, wherein the paging information is set based on the bearer QoS information set as the reception type information.

9. A core network apparatus configured to page a user terminal in an idle state when a first gateway apparatus receives a packet for the user terminal, wherein:

the core network apparatus is configured to receive a paging request signal including reception type information which indicates a reception type of the packet, from a second gateway apparatus connected to the first gateway apparatus, the reception type information including bearer information of a bearer to which the packet received by the first gateway apparatus is mapped, and

determine whether or not to page the user terminal based on the reception type information included in the received paging request signal.

10. The core network apparatus according to claim 9, wherein the core network apparatus is configured to determine whether or not to page the user terminal based on the reception type information included in the paging request signal and a congestion state of the core network apparatus.

11. A radio access network apparatus configured to page a user terminal in an idle state when a first gateway apparatus receives a packet for the user terminal, wherein:

when a core network apparatus receives a paging request signal including reception type information which indicates a reception type of the packet from a second gateway apparatus connected to the first gateway apparatus, the reception type information including bearer information of a bearer to which the packet received by the first gateway apparatus is mapped,

the radio access network apparatus is configured to receive a paging signal including paging information set based on the reception type information from the core network apparatus, and

determine whether or not to page the user terminal based on the paging information included in the paging signal from the core network apparatus.

12. A gateway apparatus configured to send a paging request signal to a core network apparatus so as to page a user terminal in an idle state from the core network apparatus via a radio access network apparatus, when a packet for the user terminal is received,

wherein the gateway apparatus is configured to set reception type information of the packet in the paging request signal-, the reception type information including bearer information of a bearer to which the packet received by the first gateway apparatus is mapped, and

send the paging request signal to the core network apparatus, so that the core network apparatus can determine whether or not to page the user terminal based on the reception type information.

13. A gateway apparatus configured to send a paging request signal to a core network apparatus so as to page a user terminal in an idle state from the core network apparatus via a radio access network apparatus, when a packet for the user terminal is received,

wherein the gateway apparatus is configured to set reception type information of the packet in the paging request signal, the reception type information including bearer information of a bearer to which the packet received by the first gateway apparatus is mapped, and

send the paging request signal to the core network apparatus, so that the core network apparatus can send paging signal including paging information set based on the reception type information to a radio access network apparatus and the radio access network apparatus can determine whether or not to page the user terminal based on the paging information included in the paging signal.
