Section: 4.3.12a.6 PCC for Restricted Local Operator Services
Content: Dynamic PCC based on the procedures described in TS 23.203[ Policy and charging control architecture ]  [6] may be used for UEs accessing Restricted Local Operator Services which involve voice services. When establishing PDN connection towards the RLOS APN with a PDN GW, according to clause 4.7.5, the PCRF provides the PDN GW with the QoS parameters, based on operator policy, including an ARP value reserved for the Restricted Local Operator Services where RLOS has a lower priority in terms of admission control than regular PDN connections The PCRF ensures that the RLOS PDN connection is used only for Restricted Local Operator Services. The PCRF rejects an IMS session established via the RLOS PDN connection if the AF (i.e. P-CSCF) does not provide an RLOS indication to the PCRF.
