Embodiment 1

[0055] figure 1 A schematic diagram of a data transmission process provided by an embodiment of the present invention, the process includes the following steps:

[0056] S101: If the state of the gateway device is a backup device, when it is recognized that the host connected to the gateway device as a backup device fails, set the pre-saved state of the host link of the host to a disconnected state .

[0057] The data transmission method provided by the embodiment of the present invention is applied to the gateway device. In different scenarios, the state of the gateway device may be the standby machine or the main machine, and when the state of the gateway device is the standby machine or the main machine, execute the corresponding standby or main machine. Host functionality.

[0058] If the state of the gateway device is a standby machine, there is at least one host connected to the gateway device as a standby (abbreviated as a standby in the embodiment of the present inve...

Embodiment 2

[0073] On the basis of the above-mentioned embodiments, in the embodiment of the present invention, a data transmission channel is connected between the gateway device serving as the standby machine and the host computer, and identifying a failure of the host computer connected to the gateway device serving as the standby machine includes :

[0074] When it is recognized that the data transmission channel is disconnected, it is determined that the host connected to the gateway device fails.

[0075] The gateway device (referred to as the backup device in the embodiment of the present invention) as the backup device is connected to the host through a data transmission channel. Fault.

[0076] When the standby machine recognizes that the data transmission channel connected to the main machine is disconnected, it determines that the main machine connected to itself has failed. The connected host is not faulty, and since the standby machine can identify whether the data transmis...

Embodiment 3

[0081] On the basis of the above-mentioned embodiments, in the embodiment of the present invention, if the state of the gateway device is a backup device, and the host connected to the gateway device as a backup device does not fail, the method further includes:

[0082] If the first downlink signaling of the service sent by the core network is received, the first downlink signaling is sent to the host connected to the gateway device serving as a standby machine through the data transmission channel.

[0083] When the host does not fail, the status of the master and backup devices of the gateway device remains unchanged, so the gateway device as the backup device (referred to as the backup device in the embodiment of the present invention) may receive the first downlink signaling of the service sent by the core network , the standby machine can send the first downlink signaling to the host computer connected to it through the data transmission channel, so in this scenario, the ...

Abstract

The invention discloses a data transmission method and apparatus, a gateway device, and a readable storage medium. The method comprises the following steps: if the state of the gateway device is standby, when a fault of a host connected with the gateway device serving as a standby computer is identified, setting the state of a pre-stored host link of the host as an off state; keeping the state ofa pre-stored standby computer link of the gateway device serving as the standby computer as an active state, wherein at least one standby computer link in the gateway device serving as the standby computer is the same as a destination signaling point DPC reachable by the host link; and switching the state of the gateway device from the standby computer to the host, and switching the standby computer link to the host link to bear signaling service. By adoption of the data transmission method and apparatus disclosed by the invention, the situation that coupling cannot be established due to the inconsistency of the backup data is avoided, it is ensured that the DPC is always reachable during the switching process of the host and the standby computer, so a core network does not perceive interruption, and the high availability of the gateway device is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data transmission method, device, gateway device and readable storage medium. Background technique [0002] To achieve high availability of gateway devices, the usual method is to deploy active and standby machines or active and standby boards. When the host is overloaded or suddenly power-off and crashes, the standby machine can replace the host as soon as possible to undertake the signaling business, and try to ensure Business is not interrupted. The speed of active / standby switching is the key factor for the normal realization of HA (High Available, high availability), and the factor that affects the switching speed is the M3UA (MTP3User Adaptation, MTP third-level user adaptation layer protocol) signaling link Can it be established as quickly as possible on the standby machine. [0003] A commonly used method in the prior art is to quickly back up the signal...
