Abstract:
An embodiment of the present disclosure discloses a method and device for managing a forwarding plane tunnel resource. The method includes sending a forwarding plane tunnel resource request message to a forwarding plane device, for enabling the forwarding plane device to allocate a forwarding plane tunnel resource based on the forwarding plane tunnel resource request message; acquiring the allocated forwarding plane tunnel resource from the forwarding plane device; and sending the acquired forwarding plane tunnel resource to a target network element, to establish a packet data network connection with the target network element. By adopting the present disclosure, the load balancing of the forwarding plane device is achieved, the signaling interaction between the control plane device and the forwarding plane device is reduced.
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:
The present invention discloses a method for processing an address resolution protocol message, a switch, and a controller. The method includes: receiving, by a switch, a flow rule that corresponds to an ARP message and that is sent from a controller; and constructing, by the switch, an ARP message according to the received flow rule, and sending the ARP message, where the flow rule includes: a match rule that corresponds to an ARP message and an action set that corresponds to an ARP message. According to the present invention, ARP-mechanism-based interaction with an external device can be implemented.
Abstract:
A paging control method and apparatus, an access gateway, a bearer connection policy control entity, a data gateway, and a network device are provided. The paging control method includes: receiving a downlink service data packet; determining whether a user terminal corresponding to the downlink service data packet is in idle state; and if the user terminal is in idle state, performing matching between the downlink service data packet and at least one bearer connection control policy, and controlling, according to a matched bearer connection control policy, paging towards the user terminal corresponding to the downlink service data packet. The present invention solves a technical problem in the prior art that network resources are wasted due to unlimited use of low-cost Internet voice/messaging services by users, and also controls paging towards a user terminal in idle state effectively, thereby improving user experience.

Abstract:
The present disclosure discloses a group charging method, a gateway device, a charging device, and a communications system, and relates to the field of communications technologies. The method includes: obtaining a group identity and personal identity information of a user; obtaining a charging rule generated according to the group identity; and establishing, according to the group identity, the personal identity information, and the charging rule, a charging session for a group account corresponding to the group identity, so that a charging system performs group charging according to the group identity and the charging rule. In the present disclosure, it is determined, according to a group identity of a user, that the user belongs to a certain group, and accordingly, a charging session is maintained for the user of the group. In this way, group charging can be achieved, thereby avoiding a complex signaling interaction process, and improving the charging efficiency.
Abstract:
Embodiments of the present invention provide a method and an apparatus for controlling a service data flow. The method includes: acquiring, by a controller, index information related to a UE, where the index information includes at least a user information index, a PDN connection index, a bearer index, and a service data flow table index that are related to the UE; sending, by the controller, the index information to a forwarder by using an entry notification message; when a first control event of a service data flow is triggered, acquiring, by the controller, a first instruction index according to the first control event, where the first instruction index includes at least one type of the index information related to the UE; and sending, by the controller, the first instruction index to the forwarder by using first control signaling.
Abstract:
The present application discloses a packet sending method and apparatus. The method includes: receiving a packet notification message sent by a first forwarding entity, where the first forwarding entity is a forwarding entity that receives a packet that is sent by a public data network PDN to a mobile terminal, and the packet notification message carries at least a terminal address of the mobile terminal; if the mobile terminal is in an idle state, paging the mobile terminal according to the terminal address of the mobile terminal, so that the mobile terminal sets up a connection to a base station eNodeB; and setting up a data channel between the eNodeB and the first forwarding entity, to connect the mobile terminal and the first forwarding entity, so that the first forwarding entity sends the packet to the mobile terminal by using the data channel and the connection.
Abstract:
The present invention relates to a flow table modifying method, a flow table modifying apparatus, and an OpenFlow network system. The flow table modifying method includes: receiving, by a switch, a modify flow entry message sent by a controller; searching, by the switch, a flow table corresponding to a flow table identifier for whether there is a flow entry matching to-be-modified target information; and in a case in which there is the flow entry matching the to-be-modified target information, changing, by the switch, a match field in the matched flow entry to a new match field. According to the flow table modifying method in an embodiment of the present invention, the switch searches the flow table corresponding to the flow table identifier for the flow entry matching the to-be-modified target information and changes the match field in the matched flow entry to the new match field.
