6.3.6 Multi-connection user profile functional entity (MUP-FE)
The multi-connection user profile functional entity contains and maintains all subscription related
information of MUEs and provides information for MPC-FE to make policy decisions and for MR-FE to make
registration management decisions. MUP-FE responds to queries for user profiles which can be stored in one
database or separated into several databases.
The following is a list of the type of information contained in the MUP-FE:
1) User information;
2) Allowed services;
3) Allowed QoS, such as bandwidth, priority, etc.;
4) Subscription and charging information;
5) Authentication and authorization information;
6) Location information;
7) Presence (e.g., online and/or offline status);
8) IP address information.
6.4 Reference points
This clause describes the reference points shown in Figure 6-6.
Reference point ANI
It exists between Applications and MAS-F. Applications and MAS-F exchange signalling messages for
application support, such as SIP messages, through this point.
Reference point As
It exists between MAS-F and SCF. SCF and MAS-F exchange signalling messages for service control, such as
SIP messages, through this point.
Reference point Pa
It exists between MAS-F and MPC-FE. MPC-FE sends the policies to MAS-F through this point. The reference
point is provided only to the trusted MAS-F.
Reference point Ps
It exists between SCF and MPC-FE. It allows QoS resource request information needed for QoS resource
authorization and reservation to be exchanged between the SCF and MPC-FE.
Reference point Ru
It exists between MR-FE and MUP-FE. MR-FE and MUP-FE exchange registration messages, such as user
profile, authentication and authorization information, presence (e.g., online and/or offline status) through
this point.
Reference point Pu
It exists between MPC-FE and MUP-FE. It allows MPC-FE to interact with MUP-FE to obtain MUE subscription
information.
Reference point Pc
It exists between MPC-FE and MC-FE. It allows MPC-FE to interact with the MC-FE to coordinate the traffic
over multiple access technologies. MC-FE reports the status of access network resources to MPC-FE, and MC-
FE could obtain service information from MPC-FE through this point.
