MOBILE COMMUNICATION METHOD AND PRIORITY LEVEL CONTROL NODE

摘要

Provided are a mobile communication method and a priority level control node for providing information, such as cell IDs, from an EPC network to an IMS fundamental. This mobile communication method is characterized in that: a call control node (P-CSCF) transmits an AAR signal of diameter base protocol to a priority level control node (PCRF); a session of an LTE network is identified in the priority level control node (PCRF); and the priority level control node (PCRF) transmits, to the call control node (P-CSCF), both an AAA signal of diameter base protocol, which is in response to the AAR signal of diameter base protocol, and the cell ID of a cell in which a mobile terminal is existent.
