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).
Claims16
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.
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.
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.
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.
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.
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.
