摘要： A method and a system for exercising policy control, a policy and charging enforcement function (PCEF), and a policy control and charging rules function (PCRF) are provided, which can solve the problem that no policy control can be exercised over application service flows without an application function (AF). The method includes of the following steps: a PCRF receiving information about an application event sent by a PCEF; and the PCRF generating a control policy for a service flow of the application according to the information about the application event, and delivering the control policy to the PCEF. In the present invention, the PCEF sends the obtained information about the application event to the PCRF, so that even when no AF is involved, the PCRF can still generate a control policy according to policy contexts including the information about the application event and the like, so as to exercise an effective policy control over the QoS guarantee, charging and gating of the service flow, thus meeting the requirements of exercising the policy control over data applications with no AF being involved.

摘要： A method and a system of realizing event detection are provided, which detect a status of an Internet Protocol (IP) connectivity access network (IP-CAN) bearer corresponding to a policy and charging control (PCC) rule by binding an Event-Trigger parameter to the PCC rule, thereby realizing small-granularity detection for the specific PCC rule and reducing the load of the system. Furthermore, a status of the IP-CAN bearer or an IP flow is realized by binding the Event-Trigger parameter to an IP-CAN identifier (ID) or an IP flow ID, so as to avoid the problem about too large granularity of the binding of event detection and IP-CAN session and reduce the burden of the IP-CAN bearer detection and message exchange.

摘要： A control method, system and function entity for reporting a bearer event of a signaling IP flow are provided. Flow identifier information such as a 5-tuple is generated for a signaling IP flow and a media IP flow so as to unify a mechanism for reporting a signaling path status and a mechanism for reporting a bearer event of a media IP flow, so that the mechanism for reporting a signaling path status is not limited by the parameter of Flow Usage, the PDP context with a signaling tag, thereby establishing corresponding PCC rules for signaling and the association between a signaling IP flow and a bearer. A method for reporting a signaling path status is further provided in the invention. In the method, for a default PDP context or a PDP context of a signaling IP flow, the predefined PCC rules are activated or signaling PCC rules generated in accordance with an Application Function address are installed, thereby an IP signaling path status is reported in accordance with rule names of the predefine PCC rules or the signaling PCC rules.

摘要： A method and a system for maintaining session continuity, in which the system includes a Handover Source Function (HOSF), a Handover Destination Function (HODF), a Handover Anchor Function-Control Plane (HOAF-CP) and a Handover Anchor Function-User Plane (HOAF-UP). The method includes a first user establishing a connection through the HOSF with the HOAF-CP and the HOAF-UP which correspond to a second user, so as to establish a session with the second user. The method further includes that, during session handover, the HODF that corresponds to the HOSF establishing another connection with the HOAF-CP and HOAF-UP though which the first user continues the session with the second user, so as to maintain the session continuity. When access address or access technology of the terminal changes, or even the terminal changes during a session, the method and the system can logically replace the connection before the handover with a new connection to ensure the session continuity.
