29.2143GPPPolicy and charging control over Rx reference pointRelease 17TS

RLOS is an optional feature supported in certain countries. Service requirements of RLOS are defined in 3GPP TS 22.101 [65] and the architectural requirements are defined in 3GPP TS 23.221 [66]. The RLOS stage 2 services description for the Evolved Packet System (EPS) is specified in 3GPP TS 23.401 [67]. The policy and charging control architecture is described in 3GPP TS 23.203 [2].

RLOS may be supported as described in clause A.5 with the following differences:

– emergency registration is replaced by RLOS registration;

– emergency session is replaced by RLOS session;

– emergency traffic is replaced by RLOS traffic;

– value "sos" is replaced by "g.3gpp.rlos";

– UNAUTHORIZED_NON_RLOS_SESSION session is returned when the service-URN AVP does not include an RLOS value, and the PCRF binds the IMS session to an IP-CAN established to an RLOS APN;

– RLOS services are not prioritized services; and

– the call back functionality is not required.
