Policy and charging control rule precedence mapping in wireless connectivity access networks

摘要

In general, techniques are described for mapping precedence domains between a network device of a content access network and a wireless communication device. For example, a Policy Charging and Enforcement Function (PCEF) entity maps relatively high-resolution mobile network policy and charging and control (PCC) rule precedence to relatively low-resolution packet filter precedence. The PCEF performs the mapping to maintain a packet filter precedence ordering for packet filters that accords with a precedence ordering among respective PCC rules from which the PCEF derives the packet filters.
