8.1 Procedure for registration

Figure 8-1 describes an initial registration procedure of user and user devices in the aspect of mobility
management. Each device can perform the registration procedure independently.

Figure 8-1 – Procedure for registration of user and devices

The interaction shown in Figure 8-1 is as follows:
1) After the user equipment (UE) UE#1 has completed the network attachment, the access MMCF (A-
MMCF) performs the location registration to the central MMCF (C-MMCF). In this step, user ID
(U_addr) and device ID (UE#1_addr, UE#2_addr, etc.) are registered in A-MMCF and C-MMCF in
transport control function.
2) UE#1 also registers to SCF for application service, and SCF updates information including user and
device.

8.2 Procedure for applications with one-to-multiple devices

Figure 8-2 describes the mobility management procedure for one-to-multiple devices with one content
source on the sender side, and multiple devices on the receiver side.
