  • Patent number: 12206717
    Abstract: Solutions are disclosed that provide for proxy-call session control function (P-CSCF) awareness of access point name (APN) or data network name (DNN). This permits the P-CSCF to enforce policies regarding use of internet protocol (IP) multimedia subsystem (IMS) resources, such as certain voice codecs (e.g., enhanced voice services, EVS) that use larger amounts of bandwidth, based on the APN/DNN assigned to a user equipment (UE). For example, certain IMS resources may be prioritized for home UEs over mobile virtual network operator (MVNO) UEs, or outbound roamers over inbound roamers, leveraging the P-CSCF's awareness of APN/DNN. In some examples, a packet gateway (PGW) or session management function (SMF) inserts APN/DNN information into a session initiation protocol (SIP) message going to the P-CSCF. In some examples, the P-CSCF retrieves APN/DNN information from a policy and charging rules function (PCRF) or a policy control function (PCF).
