In this way, a disaster recovery capability can be effectively improved and charging reliability can be ensured.
Abstract:
Embodiments of the present invention relate to a method and a device for processing a communication path. The method includes: obtaining a path processing parameter from local configuration information or from a control layer device, obtaining path information and/or a restarting counter parameter from the control layer device; increasing a path with an opposite-end device when the path information is of increasing a path, identifying the state of the path and/or the state of the opposite-end device using the path processing parameter and/or the restarting counter parameter the opposite-end device; reporting the fault state of the path and/or the reset state of the opposite-end device to the control layer device when the path fails and/or the opposite-end device is reset, releasing sessions on the failed path and/or on a path connected with the reset opposite-end device.
Abstract:
Embodiments of the present invention relate to the field of communications technologies and disclose a data flow processing method, a device, and a system, thereby solving a problem of operation interruption caused because a switch device is incapable of processing a corresponding user packet by using a received flow entry that is sent in advance by a control device, and improving working efficiency between network devices. The method includes: sending a request message to a control device, where the request message includes an action parameter requested by a switch device, and a to-be-processed packet or an identifier of a to-be-processed packet; receiving packet processing information that is sent according to the request message by the control device; and executing, according to the packet processing information, an operation corresponding to the to-be-processed packet. The embodiments of the present invention are applied in communications application technologies.
Abstract:
A method and a system for exercising policy control, a policy and charging enforcement function (PCEF) are provided, which can solve the problem that no policy control can be exercised over application service flows without an application function (AF). In the method, a PCRF receives information about an application event sent by a PCEF after subscribing the application event from the PCEF; and the PCRF generates a control policy for a service flow of the application according to the information about the application event. 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.
Abstract:
The present invention discloses a protocol processing method applied when control is decoupled from forwarding, a control plane device, and a forwarding plane device. The method includes: causing a control plane device to send an indication to a forwarding plane device according to a processing manner of a packet service processing protocol, and to deliver a negotiation parameter of the packet service processing protocol to the forwarding plane device; and causing the control plane device to receive a negotiation result of the packet service processing protocol, and to create a data path between a user equipment and a network device. The negotiation result is uploaded by the forwarding plane device and obtained according to information that includes the negotiation parameter of the packet service processing protocol.
