Title:
アイドル・モードの技術間ハンドオーバ中に複数のPDNネットワーク接続性を維持するための方法およびシステム
Document Type and Number:
Japanese Patent JP2011517534
Kind Code:
A
Abstract:
The present invention provides a method and system for supporting an optimized idle mode handoff of a user equipment from a 3GPP (EUTRAN) to a non-3GPP system (HRPD, cdma2000) where the user equipment wishes to maintain connectivity with multiple PDN networks. Namely, during an idle mode registration of the user equipment with the non-3GPP system, the user equipment will provide an indication to the access node of the non-3GPP system so that the access node in that non-3GPP system contacts the appropriate entity (HSS or AAA) on the home network of the user equipment to download the addresses of the multiple PDN gateway that are currently in use by the user equipment. This indication to the non-3GPP access node, the contact message from the access node to the home network, and the response from the home network to the access node on the non-3GPP system provide the access node with sufficient information to maintain connectivity to multiple PDN networks during an idle mode handover.
