Alice has a home PAN or UE where her video device (sink) has been registered as a PNE at the PNM. Alice is traveling to her office, and has registered her UE to the PN. For all video services she has chosen her video device as the terminating device, where it can be recorded for future viewing. She has also requested the PN service to update her on PN settings based on the service she is interested in (video devices, audio devices, printing devices, other services). For some reason, her video device (TE) becomes unavailable (Eg: power goes down or switched off by somebody else or network down.etc). The home PAN or UE deactivates this video device (TE) and makes the PN service aware of this deactivation. The PN service then lets Alice know of this event based on the capability list she has chosen.
As an effect, Alice after receiving this update may change her video terminating settings to her own UE.
Figure 13 and Figure 14 describe the PNM functionality on combination of two PANs. When PAN1 and PAN2 are physically close to each other, the user may hope to combine them into one PAN and designate UE1 as the new PAN's UE. The PNM needs to deactivate UE2 and update relative registration information (binding tables and addresses) of UE1 and PNEs in PAN2. The PNEs in PAN2 (ME2 and TE2) may keep or change the original network positions, i.e. the connection to UE2 or UE1 (described as case 1 and case 2). After the combination UE2 and ME2 need to be authorized through UE1 to get access for any new service, and then they can access those services directly.
