Problems solved by technology

In the actual network, the capabilities of peer nodes may be different. For example, desktop computers with strong software and hardware functions are more suitable for completing the control function, while ordinary mobile terminals can only complete the data carrying function.
[0007] (2) It is difficult to select control nodes
In this way, when there are no nodes with strong processing capabilities in some physical networks or network segments, it is impossible to select a suitable group agent node to complete complex control and management functions
For example, in a group in a wireless cellular network, the relay nodes may all be handheld mobile devices, and these devices cannot complete complex control functions
In this case, the relay nodes outside the cellular network cannot accurately measure the network conditions in the cellular network
Therefore, relay nodes outside the cellular network cannot replace these handheld devices as group agents

Embodiment 1

[0026] figure 2 It is a schematic structural diagram of a relay node system according to Embodiment 1 of the present invention. The relay node system includes three logical entities: a relay control entity 203 , a relay bearer entity 204 and a service quality measurement entity 205 .

[0027] Wherein, the relay control entity 203 is used to receive the relay request, select the relay bearer entity 204 for the relay task requested by the relay request, request the relay bearer entity 204 to perform the relay task, and report to the service quality measurement entity 205 sends the service quality measurement task; the relay bearer entity 204 is used to execute the relay task, and relays the service data related to the relay task; the service quality measurement entity 205 is used to perform the service quality measurement according to the above service quality measurement task , and report the obtained QoS measurement information to the relay control entity 203.

Embodiment 2

[0051] Figure 6 It is a flow chart of a business data relay method according to Embodiment 2 of the present invention, the method can be completed by the above-mentioned relay node system, and the method mainly includes the following steps:

[0052] Step S602, the relay control entity 203 receives a relay request, where the relay request is used to request relay resources for data services between the first node and the second node;

[0053] For example, a relay request from a user terminal or a service control entity may carry the addresses of the first node and the second node, the requested service type, the authentication information of the user sending the relay request, and the requested service quality request information.

[0054] Step S604, the relay control entity 203 selects the relay bearer entity 204 that bears the data service, and requests the relay bearer entity 204 to perform the relay task of the data service;

[0055] The relay control entity 203 may sele...

Embodiment 3

[0062] In the embodiment of the present invention, the process of registering by the relay bearer entity 204 with the relay control entity 205 is described.

[0063] Figure 7 It is a schematic flowchart of a relay bearer entity registering with a relay control entity in an embodiment of the present invention. Among them, the registration process is a process in which the relay bearer entity notifies the relay control entity of its basic status after the system starts or the network environment changes. It mainly includes the following steps:

[0064] 701. The relay bearer entity determines that registration needs to be performed after the system starts up or senses a change in the network environment.

[0065] The relay bearer entity first obtains the network address of the relay control entity. The specific acquisition methods include but are not limited to the following methods: A) by querying the address server or domain name resolution server (DNS), B) dynamically obta...

Abstract

The invention discloses a relay method for service data and a relay node system. The relay node system comprises a relay control entity, a relay bearing entity and a quality of service measurement entity, wherein the relay control entity is used for receiving a relay request, selecting the relay bearing entity for a relay task requested by the relay request, requesting the relay bearing entity to execute the relay task and acquiring quality of service measurement information from the quality of service measurement entity; the relay bearing entity is used for executing the relay task and relaying the service data related to the relay task; and the quality of service measurement entity is used for executing a quality of service measurement task and reporting the obtained quality of service measurement information to the relay control entity. By the method and the system, each function entity of a relay node can be flexibly configured.

Description

technical field [0001] The present invention relates to the communication field, in particular to a service data relay method and a relay node system. Background technique [0002] At present, when the communicating parties are located behind a Network Address Translation (NAT) device or a firewall device, since the communicating parties cannot directly establish a connection, it is necessary to use relay technology to realize the NAT / firewall traversal function to help the communicating parties Establish a direct connection. In addition, since the packet data network uses a best effort method to transmit data packets, its service quality is difficult to meet the requirements of multimedia services. Therefore, it is necessary to apply relay technology in the packet data network and try multiple transmission paths to improve the network service quality. [0003] Wherein, the relay technology refers to a technology in which one or more relay nodes are added to the transmissi...
