Patent Primary Examiner
A system uses deep packet inspection and a services policy database to select policy control functions based on services associated with a packet data session rather than an access point name or data network name. As a packet data session is initiated, a system management function (SMF) determines a service associated with the session and routes a policy request to one of several policy control functions (PCF or PCRF) depending on the service. Policies specific to the service may be chosen and enforced at the selected PCF/PCRF.
