            (e.g. location, amount of payment, credit card information etc.). Privacy preserving is required to consider
            operating system.

            5.2.10  Trust provisioning of mobility management
            5.2.10.1   Description

            Figure 11 describes handover scenario in mobility management as a user using User Equipment (UE) moves
            one network to another network. Handover (or handoff) refers to the process of transferring an ongoing
            session connected to the network to another channel.





























                           Figure 11 – A handover scenario among heterogeneous mobile networks


            To control handover between different mobile networks, it is necessary to identify the candidate list of Point
            of Attachments (PoAs) currently accessible by an UE. Based on this information, the UE can choose one of
            the reachable PoA to establish a new communication link. For the network selection, the handover control
            function defined in [ITU-T Y.2804] may get some information such as signal quality or available resources of
            the candidate PoAs. Trust may be applicable during network selection.
            5.2.10.2   Actors
            Network  provider:  includes  resources  and  trust-related  properties  such  as  QoE  (previous  experience  of
            network usage), and available bandwidth, etc.

            User: user profile, previous activity, etc.
            Device: device profile, available network interface, etc.

            5.2.10.3   Analysis
            Need to make a process of trust provisioning in terms of:
            •       Overall flow diagram starting from development of simple trust metric or index;
            •       Trust provisioning will be more accurate or acceptable when data is accumulated or new
                    technologies are developed.
