Technical Report on Support for fixed broadband access networks convergence
Editor's note: This clause will describe the scope of the feasibility study for P4C.
This Technical Report addresses stage 2 study for the Evolved Packet System (EPS) to facilitate policy and charging control in the fixed broadband access network in the convergent scenario where a single operator is deploying both the fixed broadband access network and the Evolved Packet Core (EPC).
The scope of this TR is to consider the convergent scenario where the PCRF controls directly the network element(s) in the fixed broadband access without the mediation of a different policy server, such as the BPCF defined in TS 23.139 [20].
The work in this TR takes the fixed broadband accesses as specified by BroadBand Forum as a reference. This does not preclude the applicability of the solutions described in this TR to other types of fixed broadband accesses.
This TR will address policy and charging control for:
- Traffic to/from fixed devices connected to the fixed broadband access network (e.g. PC, IPTV Set top Box).
- Traffic exchanged by 3GPP UEs connected via WLAN or H(e)NB when both the fixed broadband access network and the EPC are under the control of the EPS operator.
The work is organized in the building blocks and this TR address the Building block listed below, for an outline of the content of each building block refers to clause 4:
- BB1: Policy and Charging Control for supporting traffic from fixed terminals and NSWO traffic from 3GPP UEs in fixed broadband access networks (P4C-F).
- BB3: Policy and Charging Control for 3GPP UEs connected to fixed broadband access network via S2b and S2c reference points for EPC routed traffic (P4C-S2bc).
- BB4: Policy and Charging Control for EPC routed traffic over fixed broadband access networks of 3GPP UEs connected via H(e)NB in convergent scenarios (P4C-HeNB).
- BB5: Policy and Charging Control for supporting Layer 2 traffic in fixed broadband access network (P4C-FL2).
- BB6: Policy and Charging Control for 3GPP UEs connected to fixed broadband forum access networks as Trusted network in Convergence scenario (P4C-TC).
NOTE: The Building Block 2 P4C-TI is addressed in TR 23.839 [28].
