46、en 3GPP I-WLAN and GPRS systems. Such solution relies on DSMIPv6 protocol which is specified in IETF RFC 5555 10 and IETF RFC 6275 12 and is used to model the H1 reference point between the UE and the HA function. The H1 reference point enables the UE to handover from 3GPP I-WLAN towards GPRS system

47、s, and vice-versa, and granting session continuity by means of a DSMIPv6 signalling and an IP tunnel between UE and HA functions. This specification specifies only the additional procedures which are specific to I-WLAN mobility scenarios and relies on 3GPP TS 24.303 3 for DSMIPv6 procedures and 3GPP

48、 TS 24.234 5 for I-WLAN network selection and tunnel establishment. In this specification, DSMIPv6 signalling is secured as specified in IETF RFC 4877 8: IKEv2 exchange is performed by the UE with the HA before tunnel establishment. The details of the security aspects are specified in 3GPP TS 33.402

49、 14. The UE can interact with ANDSF, as described in 3GPP TS 24.302 17, and receive information useful for performing access network discovery and selection. The information is described in 3GPP TS 24.312 23. 4.2 Identities As identification towards the HA, the UE shall use the same identities as described in 3GPP TS 24.303 3. To identify the desired HA, the UE shall use the HA-APN as specified in 3GPP TS 24.303 3. The UE shall use the same identities as specified in 3GPP TS 24.008 4 to
