Abstract: 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.

Abstract: 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.

Abstract: A method, a device and a system for multicast service authorization control are provided, so as to support that a multicast authorization control point dynamically updates a user's multicast service authority information and implements multicast authorization control on the user according to the dynamically updated multicast service authority information. The method includes: acquiring a user's multicast service authority information by a multicast authorization control point in the process of interacting with a bearer control layer; and implementing multicast authorization control on the user by the multicast authorization control point according to the acquired multicast service authority information.

Abstract: A service processing method, a service processing system, and a PCRF entity are disclosed to overcome this defect in the prior art: The prior art is unable to handle services discriminatively according to the policy context information when different services require the same QoS level. The method includes: receiving bearer priority information from a PCRF entity, where the bearer priority information includes: bearer priority information of a service data stream, bearer priority information of an IP-CAN session, and/or bearer priority information of an IP-CAN bearer; and handling services according to the bearer priority information. In the embodiments of the present invention, the policy context information is converted into bearer priority information so that the PCEF handles services according to the bearer priority information. In this way, different services that require the same QoS level are handled discriminatively according to the policy context information.

Abstract: Provided are an implementing method and a communication system for a traditional terminal user accessing an IMS domain. The method allocates an IMS domain user identification including a public identification and a private identification to a traditional terminal user on an AGF entity controlled by an AGCF entity, and establishes a mapping relation between the IMS domain user identification and the line identification of the user. When receiving a command or message for a certain user terminal sent from the AGF entity, the AGCF entity determines the IMS domain user identification of the user according to the mapping relation and sends a corresponding SIP message to the IMS domain.

Abstract: A method, system and device for implementing security control are provided. The method for implementing security control includes: receiving, by the Policy and Charging Enforcement Function (PCEF) entity, security control policy information from the Policy Control and Charging Rules Function (PCRF) entity; and executing, by the PCEF entity, user security control according to the security control policy information. The provided method, system, and device may provide security control for the user session in the Policy Charging Control (PCC) architecture.

Abstract: A method, a system, and an apparatus for controlling multicast bearer resources are disclosed. The method includes: a network entity in the RACS receives a request of controlling a multicast bearer resource and controls the multicast bearer resource according to the request. The method, the system and the apparatus disclosed herein can control the multicast bearer resource in the NGN.

Abstract: A method, apparatus, and system for controlling multicast bearer resources are disclosed, which employ a resource and admission control subsystem (RACS) to control the multicast bearer resources. The method includes: a network entity in a RACS receives a request for controlling multicast bearer resources from a bearer-layer network entity and controls the multicast bearer resources. The network entity in the RACS includes: a receiving unit adapted to receive a request for controlling multicast bearer resources from a bearer-layer network entity and a control unit adapted to control the multicast bearer resources.

Abstract: A method and a system for implementing a self service by using a circuit switched terminal are provided. The method includes receiving a self-service signaling associated with a self service from a circuit switched terminal; and converting the self-service signaling to a self service request, which is adapted to indicate an IMS network entity associated with the self service to conduct a service data configuration; and sending the self service request to the IMS network entity associated with the self service. The solution provided enables a user using the conventional circuit switched terminal to conveniently implement the self service such as registration activation, registration cancellation, and authentication of the self service.

Abstract: A control method, system and function entity for reporting a bearer event of a signaling IP flow are provided. 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.

Abstract: 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 establishing a session with the second user; 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 the access address or the access means of the terminal changes, or even the terminal changes during a session, embodiments of the present invention can logically replace the connection before the handover with a new connection to ensure the session continuity.
