Embodiment 1

[0047] This embodiment provides a method for link keep-alive between AP and AC. The flowchart is as follows: figure 1 As shown, detailed as follows:

[0048] The method for keeping alive the link between the AP and the AC provided in this embodiment is applied to the equipment of the wireless access point AP. Including the following steps:

[0049] Step S101, within a preset time period after the AP device receives the message sent by the AC server, it is detected whether the AP device has received the message sent by the AC server again; when it is detected that the AP device has not received the message again To the message sent by the AC server, step S102 is executed.

[0050] The AP device receives the message sent by the AC server as the time starting point and enters the time period;

[0051] First, in the first time period, it is detected whether the AP device has received the message sent by the AC server again, and when it is detected that the AP device has not received the ...

Embodiment 2

[0071] This embodiment provides a method for link keep-alive between AP and AC. The flowchart is as follows: figure 2 As shown, detailed as follows:

[0072] The method for keeping alive the link between the AP and the AC provided in this embodiment is applied to the equipment of the wireless access point AP. Including the following steps:

[0073] Step S201, within a preset time period after the AP device receives the message sent by the AC server, it is detected whether the AP device receives the message sent by the AC server again; when it is detected that the AP device has not received the message again To the message sent by the AC server, step S202 is executed.

[0074] Step S202: Send a heartbeat message to the AC server, and increase the heartbeat keepalive failure count by one.

[0075] Step S203: It is detected whether a message sent by the AC server is received within the next said time period, if not, step S204 is executed.

[0076] Step S204, detecting whether the heartb...

Embodiment 3

[0088] This embodiment provides a method for link keeping alive between AC and AP, and the flowchart is as follows image 3 As shown, detailed as follows:

[0089] The method provided in this embodiment is applied to an AC server.

[0090] Step S301: After the AC server receives the message sent by the AP device, it detects whether the message sent by the AP device is received again.

[0091] Start timing with the AC server receiving the packet sent by the AP device as the starting point, and detect whether the packet sent by the AP device is received again.

[0092] Wherein, the message includes a business message and a heartbeat message.

[0093] Step S302: When the AC server does not receive the message sent by the AP device within the preset time period, it is considered that the AP device is offline; otherwise, it is considered that the AP device is online.

[0094] The link keep-alive method between the AC and the AP provided in this embodiment corresponds to the link keep-alive me...

Abstract

The invention provides a method and system for keeping alive links between AP and AC and between AC and AP. The method for keeping the alive link between the AP and the AC comprises the following steps: S11, within a preset time period after an AP device receives a message sent by an AC server, detecting whether the AP device receives the message sent by the AC server again; if not, continuing toexecute step S12; S12, sending a heartbeat message to the AC server, and adding 1 to a heartbeat keep-alive failure count; S13, detecting whether the message sent by the AC server is received within the next time period, and if not, executing step S14; S14, detecting whether the heartbeat keep-alive failure count exceeds a count threshold; when the heartbeat keep-alive failure count does not exceed the count threshold, returning to step S12; and when the heartbeat keep-alive failure count exceeds the count threshold, deeming that the AC server is offline. The keep-alive method can effectivelyreduce the pressure of the AC server and the network broadband pressure when the AC server is busy.

Description

Technical field [0001] The present invention relates to the technical field of network communication, in particular to a method and system for link keeping alive between AP and AC, and AC and AP. Background technique [0002] In urban wireless communication solutions, thin APs and AC devices are used as the infrastructure of the wireless network. When the number of APs increases, the number of wireless access users increases, and the packets that need to be processed by the AC increase exponentially, and the AC server load problem becomes increasingly severe. [0003] For the communication between the wireless access point AP and the wireless access controller AC, the TR069 standard should be complied with; when the AC receives a service message from the AP, it should reply with a response message to indicate that it has received the service message Up. [0004] Heartbeat messages are mainly used between the wireless access point AP and the wireless access controller AC to detect a...
