20080232376 | CONTROL METHOD, SYSTEM AND FUNCTION ENTITY FOR REPORTING BEARER EVENT OF SIGNALING IP FLOW - 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. | 09-25-2008 |
20090147929 | METHOD AND APPARATUS FOR TRANSMIT-RECEIVING EMERGENCY SERVICE - Methods and apparatuses for transmitting and receiving emergency service are provided to solve the problem that the user maliciously performs emergency registration with the emergency user ID to receive the unauthorized service. The method for initiating callback in the emergency service includes forwarding the request message to the callee connection network and informing the callee connection network of the identity of the initiator identity after the callback initiator side authenticates the identity of the initiator of the received request message. The method for receiving callback in the emergency service includes: recognizing, by the callee connection network, the identity of the initiator who initiates the callback request message transmitted from the call initiator-side network and performing post-processing according to whether the identity of the initiator is a valid PSAP. | 06-11-2009 |

20100017846 | SERVICE PROCESSING METHOD AND SYSTEM, AND POLICY CONTROL AND CHARGING RULES FUNCTION - 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. | 01-21-2010 |
20100039941 | METHOD, SYSTEM AND ENTITY OF REALIZING EVENT DETECTION - 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. | 02-18-2010 |
20100043053 | METHOD, SYSTEM, AND ENTITY FOR EXERCISING POLICY CONTROL - 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. | 02-18-2010 |
