Abstract

Claims (44)

1 . A relay session establishing method, performed by a remote device, wherein the method comprises:

determining a relay service code, RSC, of a traffic, according to description information of the traffic to be transmitted, and an RSC corresponding to each traffic description, the traffic description having at least one characteristic of IP address, domain information, and application identification;

wherein the description information of the traffic comprises at least one characteristic of application identification, domain information, IP address, and traffic attribute of the traffic;

wherein the relay service code is used for indicating a traffic attribute of the traffic in the session establishment process;

discovering a relay device according to the relay service code;

establishing a relay session with the relay device, wherein the relay session is used for transmitting data of the traffic.

2 . The method according to claim 1 , wherein discovering the relay device according to the relay service code comprises:

receiving discovery messages broadcasted by multiple devices, wherein the discovery message of each device carriers a relay service code supported by the device or authorized to be supported by the device;

determining a device with a discovery message carrying the relay service code corresponding to the traffic as the relay device.

3 . The method according to claim 1 , wherein discovering the relay device according to the relay service code comprises:

sending a discovery request message, wherein the discovery request message comprises the relay service code;

receiving a discovery response message, and determining a device sending the discovery response message as the relay device.

4 . A non-transitory computer-readable storage medium storing computer-executable instructions, when being executed by a processor, the computer-executable instructions are used to implement the relay session establishing method according to claim 1 .

5 . A chip, comprising a processing module and a communication interface, wherein the processing module is configured to execute the relay session establishing method according to claim 1 .

6 . A relay session establishing method, performed by a relay device, wherein the method comprises:

determining a remote device for relaying according to a relay service code, RSC, of a traffic, wherein the relay service code is used for indicating a traffic attribute of traffic supported by the relay device or authorized to be supported by the relay device;

establishing a relay session with the remote device, wherein the relay session is used for transmitting data of the traffic;

wherein determining the remote device for relaying according to the relay service code comprises:

receiving a discovery request message sent by a remote device, wherein the discovery request message comprises a relay service code corresponding to the traffic, wherein the relay service code in the discovery request message is determined by the remote device according to description information of the traffic to be transmitted, and an RSC corresponding to each traffic description, the traffic description having at least one characteristic of IP address, domain information, and application identification, wherein the description information of the traffic comprises at least one characteristic of application identification, domain information, IP address, and traffic attribute of the traffic;

sending a discovery response message to the remote device if the relay service code in the discovery request message is the relay service code corresponding to the traffic attribute supported by the relay device or authorized to be supported by the relay device.

7 . The method according to claim 6 , wherein the relay service code corresponding to the traffic attribute supported by the relay device or authorized to be supported by the relay device is pre-configured or configured by a network device.

8 . The method according to claim 6 , wherein determining the remote device for relaying according to the relay service code comprises:

broadcasting a discovery message, wherein the discovery message comprises the relay service code.

9 . A relay device, comprising:

a processor, a memory, and an interface for communicating with other relay devices or network devices;

the memory stores computer-executable instructions;

the processor executes the computer-executable instructions stored in the memory, so that the processor executes the relay session establishing method according to claim 6 .

10 . A non-transitory computer-readable storage medium storing computer-executable instructions, when being executed by a processor, the computer-executable instructions are used to implement the relay session establishing method according to claim 6 .

11 . A chip, comprising a processing module and a communication interface, wherein the processing module is configured to execute the relay session establishing method according to claim 6 .

12 . A remote device, comprising:

a processor, a memory, and an interface for communicating with a relay device;

the memory stores computer-executable instructions;

the processor executes the computer-executable instructions stored in the memory, so that the processor is caused to:

determine a relay service code, RSC, of a traffic, according to description information of the traffic to be transmitted, and an RSC corresponding to each traffic description, the traffic description having at least one characteristic of IP address, domain information, and application identification;

wherein the description information of the traffic comprises at least one characteristic of application identification, domain information, IP address, and traffic attribute of the traffic;

wherein the relay service code is used for indicating a traffic attribute of the traffic in the session establishment process;

discover a relay device according to the relay service code;

establish a relay session with the relay device, wherein the relay session is used for transmitting data of the traffic.

13 . The remote device according to claim 12 , wherein the processor is caused to:

control the interface to receive discovery messages broadcasted by multiple devices, wherein the discovery message of each device carriers a relay service code supported by the device or authorized to be supported by the device;

determine a device with a discovery message carrying the relay service code corresponding to the traffic as the relay device.

14 . The remote device according to claim 12 , wherein the processor is caused to control the interface to:

send a discovery request message, wherein the discovery request message comprises the relay service code;

receive a discovery response message, and determining a device sending the discovery response message as the relay device.
