Abstract

The application discloses a message response method and device, a communication device and an access service system. The method comprises the following steps: after a user plane node receives a first PADI message sent by a CPE, first information and / or second information are generated, the first information is used for identifying a Cookie of the access service system, and the second information is used for identifying a Name of the access service system; the user plane node sends a first PADO message to the CPE, the first PADO message carries the first information and / or the second information; the first PADO message is a response message of the first PADI message; after the user plane node receives a first PADR message sent by the CPE, the user plane node interacts with a control plane node to obtain a first PADS message from the control plane node, the first PADS message carries a session identifier; and the user plane node sends a second PADS message to the CPE, the second PADS message is generated based on the first PADS message, and the first PADS message carries the session identifier.

Claims

1. A method of responding to a packet, characterized by, Applied to an access service system, the access service system including a control plane node and at least one user plane node, the method includes: After receiving the first PADI message sent by the client device CPE, the user plane node generates first information and / or second information. The first information is used to identify the Cookie of the access service system, and the second information is used to identify the Name of the access service system. The user plane node sends a first PADO message to the CPE, the first PADO message carrying the first information and / or the second information; the first PADO message is a response message to the first PADI message; After receiving the first PADR message sent by the CPE, the user plane node interacts with the control plane node to obtain the first PADS message from the control plane node. The first PADS message carries a session identifier. The user plane node sends a second PADS message to the CPE. The second PADS message is generated based on the first PADS message, and the first PADS message carries a session identifier. Before the user plane node communicates with the control plane node, the method further includes: The user plane node establishes a communication channel with the control plane node; The user plane node receives a user plane identifier UP-ID sent by the control plane node through a communication channel with the control plane node. The UP-ID is used to identify the user plane node. The user plane node interacts with the control plane node to obtain the first PADS message from the control plane node, including: The user plane node carries the UP-ID and the first information and / or the second information in the first PADI message, thereby generating a second PADI message; The user plane node sends the second PADI message to the control plane node through the communication channel with the control plane node; The user plane node receives a second PADO message sent by the control plane node through a communication channel with the control plane node. The second PADO message carries the UP-ID and the first information and / or the second information. The user plane node discards the second PADO message; The user plane node carries the UP-ID in the first PADR message to generate the second PADR message; The user plane node sends the second PADR message to the control plane node through the communication channel with the control plane node; The user plane node receives a first PADS message sent by the control plane node through a communication channel with the control plane node. The first PADS message carries the UP-ID and session identifier. The user plane node removes the UP-ID from the first PADS message to generate a second PADS message.

2. The method according to claim 1, characterized in that, After the user plane node receives the first PADI message sent by the CPE, the method further includes: the user plane node buffering the first PADI message; After the user plane node receives the first PADR message sent by the CPE, the method further includes: the user plane node buffering the first PADR message.

3. The method of claim 1, wherein, The second PADI message, the second PADO message, the second PADR message, and the first PADS message carry at least one tag, the at least one tag including a first tag, the first tag being used to identify the UP-ID.

4. A message-based response device, characterized in that, A user plane node applied in an access service system, the access service system further comprising a control plane node; the apparatus includes: The communication unit is used to receive the first PADI message sent by the CPE; A processing unit is configured to generate first information and / or second information, wherein the first information is used to identify the cookie of the access service system and the second information is used to identify the name of the access service system; The communication unit is further configured to send a first PADO message to the CPE, the first PADO message carrying the first information and / or the second information; after receiving a first PADR message sent by the CPE, interact with the control plane node to obtain a first PADS message from the control plane node, the first PADS message carrying a session identifier; and send a second PADS message to the CPE, the second PADS message being generated based on the first PADS message, the first PADS message carrying a session identifier. The communication unit is used to establish a communication channel with the control plane node; and to receive a user plane identifier UP-ID sent by the control plane node through the communication channel with the control plane node, wherein the UP-ID is used to identify the user plane node; The processing unit is configured to carry the UP-ID and the first information and / or the second information in the first PADI message, thereby generating a second PADI message; The communication unit is used to send the second PADI message to the control plane node through a communication channel with the control plane node; The communication unit is configured to receive a second PADO message sent by the control plane node through a communication channel with the control plane node. The second PADO message carries the UP-ID and the first information and / or the second information. The processing unit is used to discard the second PADO message; The processing unit is configured to carry the UP-ID in the first PADR message to generate a second PADR message; The communication unit is configured to send the second PADR message to the control plane node through a communication channel with the control plane node; and to receive the first PADS message sent by the control plane node through the communication channel with the control plane node, wherein the first PADS message carries the UP-ID and session identifier. The processing unit is used to strip the UP-ID from the first PADS message to generate a second PADS message.

5. An access service system, characterized in that, The access service system includes a control plane node and at least one user plane node, the user plane node being used to perform the method as described in any one of claims 1 to 3.

6. A communication device, characterized in that, include: A processor and a memory for storing a computer program, the processor for calling and running the computer program stored in the memory to perform the method as described in any one of claims 1 to 3.
