Authentication method and apparatus for user equipment and LIPA network entities
First Claim
1. An authentication method for local internet protocol access (LIPA) network entity and user equipment (UE), adapted to a cross-LIPA communication situation getting involved with a UE end, a visiting LIPA network entity end (LIPAV), and a home LIPA network entity end (LIPAH), and comprising:
- successfully registering to a CN by said UE end via said LIPAV, to attain mutual trust relationship of said UE end and said LIPAV;
successfully registering to said CN by said UE end via said LIPAH, to attain mutual trust relationship of said UE end and said LIPAH; and
requesting said UE end by said LIPAH for re-authentication and successfully re-authenticating said UE end via said LIPAV, to attain mutual trust relationship of said LIPAV and said LIPAH,wherein a mutual authentication of said UE end, said LIPAV, and said LIPAH is attained by a user end triggered authentication procedure,wherein said mutual authentication procedure comprises;
sending a specific message to said LIPAH by said LIPAV to trigger said UE end to authenticate to said CN with said LIPAV and said LIPAH being involved, and said LIPAH forwarding said specific message to said CN, to enable said CN to authenticate said UE end;
in an existing universal mobile telecommunications system authentication and key agreement procedure, adding forwarding functions to said LIPAH and said LIPAV, including sending a user authentication request message by said LIPAV, forwarding a user authentication request message by said LIPAH, and forwarding a user authentication response message by said LIPAV; and
in an existing security mode control procedure, adding another forwarding function to said LIPAH and said LIPAV, including forwarding a security mode command message by said LIPAH, and forwarding a security mode completion message by said LIPAV.

Abstract
An authentication method for user equipment (UE) and LIPA network entities is applicable to a cross-LIPA communication environment having an UE end, a visiting LIPA network entity end (LIPAV), and a home LIPA network entity end (LIPAH). The UE end successfully registers to a core network (CN) via the LIPAV, thereby attaining mutual trust relationship between the UE end and the LIPAV. The UE end successfully registers to the CN via the LIPAH, thereby attaining mutual trust relationship between the UE end and the LIPAH. The LIPAH requests the UE end via the LIPAV for successfully re-authenticating the CN, thereby attaining mutual trust relationship between the LIPAV and the LIPAH.

4. An authentication method for local internet protocol access (LIPA) network entity and user equipment (UE), adapted to a cross-LIPA communication situation getting involved with a UE end, a visiting LIPA network entity end (LIPAV), and a home LIPA network entity end (LIPAH), and comprising:
-
successfully registering to a CN by said UE end via said LIPAV to attain mutual trust relationship of said UE end and said LIPAV;
successfully registering to said CN by said UE end via said LIPAH, to attain mutual trust relationship of said UE end and said LIPAH; andrequesting said UE end by said LIPAH for re-authentication and successfully re-authenticating said UE end via said LIPAV, to attain mutual trust relationship of said LIPAV and said LIPAH, wherein a mutual authentication of said UE end, said LIPAV, and said LIPAH is attained by an authentication procedure which is triggered by a simplified routing area update (RAU) procedure, wherein said authentication procedure triggered by said simplified RAU procedure comprises; sending a specific message of a RAU request by said LIPAV to said LIPAH, to trigger said UE end to authenticate to said CN end with said LIPAV and said LIPAH being involved, forwarding said specific message of the RAU request to said CN by said LIPAH, and verifying the content information of said specific message by said CN; in an existing universal mobile telecommunications system authentication and key agreement procedure, adding forwarding functions to said LIPAH and said LIPAV, including forwarding a user authentication request message by said LIPAH, forwarding a user authentication response message to said LIPAH by said LIPAV, and forwarding a user authentication response message to said CN by said LIPAH; in an existing security mode control procedure, adding another forwarding functions to said LIPAH and said LIPAV, including forwarding a security mode command message by said LIPAH, and forwarding a security mode completion message by said LIPAV; and
sending a RAU response to said LIPAH by said CN, and forwarding said RAU response to said LIPAV by said LIPAH to complete said simplified RAU procedure. - View Dependent Claims (5, 6, 7)
