ROUTING METHOD, ROUTING SYSTEM, MOBILE NODE, HOME AGENT, AND HOME BASE STATION

摘要

Disclosed in a technique for registering, with a home agent, a routing rule for specifying packets destined to a second address generated from a home prefix as well as a home address and/or flow destination interfaces without increasing the number of messages. According to this technique, when a UE 10 is communicating (flow 1 and flow 2) with a CN 17 using the HoA, a routing rule indicating, for example, that flow 1 of packets destined to a HNP address is forwarded to a 3GPP interface IF1 and flow 2 of packets destined to the HNP address is forwarded to a WLAN interface IF2 is registered with a P-GW 13 through a routing rule registration message 21 such as a BU message at the time of starting simultaneous connections of the interfaces IF1 and IF2.
