Abstract:
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.
