Figure I.3 – Mobility management procedure based on MIP
1) After detecting active device, the device group (S1) is requested to register its HoA and CoA (S1,
T1_2 respectively).
2) Mobility Binding Information Management module creates the mobility binding list according to the
request.
3) When CN transmits packets, IP-in-IP Tunnelling module refers to Mobility binding information, and
then the packets are encapsulated.
4) Packets are delivered to the device via IP-in-IP tunnel, and decapsulated.
5) If the user switch over active devices, process of 2) ~ 4) are to be repeated.
