Patent number: 8155020Abstract: Techniques for supporting policy control and charging (PCC) functions in a wireless communication network are described. In one design, a Policy Control and Charging Rules Function (PCRF) may receive a request from a first network entity (e.g., a home agent) to establish a PCC session for a user equipment (UE) accessing the first network entity using a mobility protocol (e.g., Mobile IP). The PCRF may determine the mobility protocol used by the UE based on an IP-CAN Type parameter included in the request. The PCRF may determine PCC rules for the PCC session based on the mobility protocol and may send the PCC rules to the first network entity. The first network entity may apply the PCC rules on packets for the PCC session and may count each packet for charging. A second network entity may forward the packets but would not count these packets for charging.Type: GrantFiled: January 13, 2009Date of Patent: April 10, 2012Assignee: QUALCOMM IncorporatedInventors: Gerardo Giaretta, Kalle I.

Patent number: 8042170Abstract: In a communication session in which data flows with encrypted data packets pass through a monitoring intermediary for data traffic control. The encrypted data packets include SPIs (Secured Parameter Indexes) which are used to identify SAs (Security Associations) for data decryption. During the initial signaling process for the communication session, the nodes seeking the communication session include the SPIs in the signaling messages and send the signaling messages through the monitoring intermediary which in turn matches the SPIs of the signaling messages with the corresponding SPIs extracted from the data packets. In enforcing data traffic control, the monitoring intermediary allows data flows to pass through if comparison matches in the SPIs are found. Otherwise, the data flows are rejected.Type: GrantFiled: July 12, 2005Date of Patent: October 18, 2011Assignee: QUALCOMM IncorporatedInventors: Arungundram C.
