Embodiment 1

[0022] This embodiment provides a data transmission method, figure 1 It is a flow chart of the data transmission method provided by the embodiment of the present invention. The executive subject of this embodiment is a home gateway, which is located on the user side, and the home gateway in this embodiment only retains part of the functions compared with the traditional gateway. For example, the remote management function, but compared with the traditional gateway, the hardware interface of the home gateway remains unchanged.

[0023] like figure 1 As shown, the data transmission method provided in this embodiment includes:

[0024] Step 101: Receive a first processing result sent by a virtual gateway after processing a first service request, and store the first processing result in a random access memory, wherein the first service request is sent by a terminal.

[0025] Wherein, the virtual gateway is located on the network side, and the virtual gateway in this embodiment c...

Embodiment 2

[0037] This embodiment is a further supplementary description to the above-mentioned embodiment, figure 2 is a flowchart of a data transmission method provided by another embodiment of the present invention, such as figure 2 As shown, the method includes:

[0038] Step 201, receiving a first service request sent by a terminal.

[0039] Step 202, sending the first service request to the virtual gateway, so that the virtual gateway processes the first service request and generates a first processing result.

[0040] Step 203, receiving the first processing result sent by the virtual gateway after processing the first service request, and storing the first processing result in the RAM, wherein the first processing result includes at least one of the following results: the same as the first MAC (Media Access Control, referred to as MAC) address table, IP (Internet Protocol, referred to as IP) address allocation table, routing table, and quality of service Qos (Quality of Servi...

Embodiment 3

[0050] This embodiment is a further supplementary description to the above-mentioned embodiment, image 3 is a flow chart of a data transmission method provided by another embodiment of the present invention, such as image 3 As shown, the method includes:

[0051] Step 301, receiving the first processing result sent by the virtual gateway after processing the first service request, and storing the first processing result in the RAM, wherein the first processing result includes at least one of the following results: the same as the first The MAC address table, IP address allocation table, routing table, and service quality Qos policy table corresponding to the business.

[0052] Step 302, backing up the first processing result in the RAM to the flash memory.

[0053] Step 301 and step 302 are respectively the same as step 101 and step 102 in the above embodiment, and will not be repeated here.

[0054] Step 303: If the first service request sent again by the terminal is rec...

Abstract

The invention provides a method, a device and a system for data transmission, wherein the method comprises the following steps of: receiving a first processing result of processing a first service request from a virtual gateway, and storing the first processing result in a random access memory, wherein the first service request is transmitted by a terminal; backing up the first processing result in the random access memory to a flash memory; if the first service request transmitted again by the terminal is received, judging whether the first processing result is in the random access memory, if not, loading the first processing result in the flash memory to the random access memory; reading the first processing result in the random access memory, and processing according to the first processing result. According to the method, the device and the system for data transmission provided by the invention, when the terminal transmits the same service request to a home gateway, the home gateway has no need of transmitting the service request to the virtual gateway every time, thus, signalling overhead may be reduced.

Description

technical field [0001] The present invention relates to communication technology, in particular to a data transmission method, device and system. Background technique [0002] At this stage, in the deployment scenario of a virtualized gateway, some functions of the home gateway device are performed by the virtual gateway. The terminal sends a service request to the home gateway, and the home gateway forwards the service request to the virtual gateway. The virtual gateway forwards the service to the home gateway. The request is processed, and the processing result is sent to the home gateway, and the home gateway performs subsequent operations such as forwarding or analysis according to the obtained processing result. [0003] However, when the terminal sends the same service request to the home gateway, the home gateway needs to send the service request to the virtual gateway every time, and the virtual gateway will process it and then send the processing result to the home ...
