MOBILE COMMUNICATION METHOD AND GATEWAY APPARATUS

摘要

A mobile communication method comprises: a step in which a gateway apparatus (P-GW) transmits, in response to a reception of a "Proxy Binding Update" transmitted by a gateway apparatus (S-GW), a "Proxy Binding Acknowledgement", which includes an "O Flag setting information" indicating whether a DNSv6 address has been assigned to a mobile station (UE), to the gateway apparatus (S-GW); and a step in which the gateway apparatus (S-GW), when having received the "O Flag setting information" indicating that the DNSv6 address has been assigned to the mobile station (UE), uses an "O Flag" of RA to inform the mobile station (UE) that there is no need to acquire the DNSv6 address by use of a DHCP request signal.
