A paging method of the present invention is a paging method for paging a UE () in an idle state when a P-GW () receives a packet for the UE () and includes the steps of: in a S-GW (), setting reception type information of the packet received by the P-GW () in 'Downlink Data Notification' and sending the 'Downlink Data Notification' to an MME () and an SGSN (), and in the MME () and SGSN (), determining whether or not to page the UE () based on the reception type information included in the &#x201c;Downlink Data Notification&#x201d; from the S-GW ().

Paging method, core network apparatus, radio access network apparatus and gateway apparatus

A mobile communication method according to the present invention includes the steps of: transmitting an 'Extended Service Request' from a mobile station UE in Idle mode to a mobility management node MME via a radio base station eNodeB; transmitting an 'Initial UE Context Setup Request' from the mobile station UE to the radio base station eNodeB, the &#x201c;Initial UE Context Setup Request containing priority call information; and preferentially allocating resources to the E-RAB for the mobile station UE by the radio base station eNodeB based on the priority call information contained in the received &#x201c;Initial UE Context Setup Request.&#x201d;

Mobile communication method, radio access network apparatus and mobile station

A mobile communication method according to the present invention includes a step of establishing, by a session control node S/P-CSCF, a prioritized-call bearer between a gateway device P-GW and a mobile station UE when an Invite signal including prioritized-call information is received; a step of transmitting, by the session control node S/P-CSCF, the Invite signal including the prioritized-call information to the gateway device P-GW after the prioritized-call bearer is established; and a step of transmitting, by the gateway device P-GW, the Invite signal including the prioritized-call information to the mobile station UE.
