Zusammenfassung:	Communication networks and methods are disclosed for performing charging in LTE/EPC communication networks (100). In an LTE/EPC communication network (100), a PCRF (110) stores charging rules for online and offline charging. To perform charging for a session, LTE network elements (112-114) that are serving the session request charging rules from the PCRF (110). The PCRF (110) identifies the charging rules, and assigns a unique LTE charging identifier for the session across all network elements in the LTE/EPC communication network (100). The LTE network elements (112-114) receive the charging rules from the PCRF (110) along with the LTE charging identifier for the session. The LTE network elements (1 12-114) generate charging messages for the session, and insert the LTE charging identifier in the charging messages. The LTE network elements (112-114) then transmit the charging messages to a charging system (118-119), such as an OCS or an OFCS. The OCS/OFCS may then correlate the charging messages for the session based on the LTE charging identifier.
