Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0028] WTP can be an access point (Access Point, AP), which is responsible for simple functions such as encryption and decryption of packets, and statistics of radio frequency air interfaces. AC is responsible for managing one or more WTPs.

[0029] figure 1 It is a schematic flowchart of a method for transmitting data provided by an embodiment of the present invention. figure 1 The method can be performed by a network side device, such as a...

Abstract

The embodiment of the invention provides a data transmission method and network side equipment. The data transmission method comprises the following steps that whether a CAPWAP (control and provisioning of wireless access point) data channel has the data transmission or not is confirmed; and under the condition that the CAPWAP data channel has the data transmission, the sending of keep-alive messages is stopped. In the embodiment, because the keep-alive messages are not sent in the data transmission process, so the CAPWAP link breaking caused by keep-alive message loss can be prevented, and the reliability of the ACPWAP link is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and more specifically, to a data transmission method and a network side device. Background technique [0002] Control and Provisioning of Wireless Access Points (CAPWAP) is a standard protocol for managing access controllers (Access Controller, AC) and wireless termination points (Wireless Termination Points, WTP). CAPWAP includes data tunneling. The AC and WTP periodically check the status of the data tunnel through Keep-alive packets. If the keep-alive packets of the data tunnel are lost during data transmission, the CAPWAP link will be disconnected, which affects WTP services. Contents of the invention [0003] The invention provides a data transmission method and network side equipment, which can improve the reliability of the CAPWAP link. [0004] In one aspect, the present invention provides a method for transmitting data, comprising: [0005] Determin...
