context: MN can only send Binding Updates for its own Home Address and not for other MNâs Home Addresses. Figure 7 provides the flow for the initial DS-MIPv6 bootstrapping. Figure 7: DS-MIPv6 bootstrapping based on IKEv2 1) The UE discovers the PDN GW address based on the procedure specified in 23.401. 2) The UE starts an IKEv2 exchange with the PDN GW. The first part of this exchange is an IKE_SA_INIT exchange. 3) The UE indicates that EAP is used for IKEv2 authentication and an EAP exchange is performed. EAP is carried over IKEv2 between the UE and the PDN GW and over the AAA protocol between the PDN GW and the AAA server. 4) During the IKEv2 exchange, the PDN GW allocates an IPv6 Home Address and send it to the UE in a IKEv2 Configuration Payload. 5) As a result of the previous steps, an IPsec SA is established to protect DS-MIPv6 signalling. 6) The UE sends the MIP Binding Update message to the PDN GW. 7) The PDN GW processes the binding update. The PDN GW sends the MIP Binding Ack to the
description: DS-MIPv6 (Dual stack Mobile IPv6) is a protocol that enables mobile devices to maintain connectivity while moving between different networks, supporting both IPv4 and IPv6. It allows for seamless handovers and session persistence across network boundaries.
explanation: The text explicitly states that DS-MIPv6 is a protocol used for mobile device connectivity and session management.
