Description

Technical Field

[0001] The embodiments of the present application relate to the field of mobile communication technology, and in particular to a method for implementing device online and offline, an electronic device, and a computer-readable medium. Background Art

[0002] As a basic telecommunications service, traditional short messages are widely used, and all walks of life pay attention to the use of short messages, such as identity code verification SMS, notification SMS, and marketing SMS, etc. SMS still "permanently exists" in various forms and is an indispensable communication tool for us, so there are higher requirements for the availability of the Short Message Service Center (SMSC) system.

[0003] However, the current disaster recovery method of the SMSC system is to manually trigger disaster recovery by manually blocking the link or stopping the service process after receiving user complaints or maintenance personnel discovering system failures. This method prolongs the time that SMS services are affected. From the perspective of operator customers, this period will cause a certain loss of revenue; from the perspective of end users, the inability to send and receive SMS, especially verification code SMS, will have a certain impact on users' daily travel and life.

[0078] In some exemplary embodiments, when no heartbeat detection response message is received from the second device within a preset time, it is determined that the second device has not been restored online, and the process returns to the step of sending a heartbeat detection request message to the second device.

[0085] In some exemplary embodiments, based on the heartbeat management mechanism, the external or internal equipment is automatically sensed to be online, and the online operation is automatically realized to prepare for the subsequent automatic triggering of disaster recovery rollback, thereby shortening the time when the SMS service is affected, reducing the impact on operators and end users, and improving the availability of the system.

[0086] In order to illustrate the device online and offline method based on linked heartbeat detection in the embodiment of the present application, two examples are listed below for illustration. The examples listed are only for convenience of explanation and cannot be used to limit the protection scope of the embodiment of the present application.

[0087] Example 1

[0088] This example describes a method for internal devices in an SMSC system to automatically go online and offline due to an abnormal triggering of an external network element.

[0089] like Figure 2 As shown, the execution process of SMSC system 1 and SMSC system 2 is the same, and this example takes SMSC system 1 as an example for description.

[0090] like Figure 2 As shown, the SMSC system 1 includes: N external interface devices A deployed in N+1 load sharing mode, N external interface devices B deployed in N+1 load sharing mode, N message processing devices deployed in N+1 load sharing mode, and N business logic processing devices and operation and maintenance devices deployed in N+1 load sharing mode.

[0091] The operation and maintenance equipment establishes links with N external interface devices A, N external interface devices B, N message processing devices, and N business logic processing devices respectively. Each external interface device A establishes a link with external network element A and N message processing devices. Each external interface device B establishes a link with external network element B and N message processing devices. Each message processing device establishes a link with N external interface devices A, N external interface devices B, and N business logic processing devices. Each business logic processing device establishes a link with N message processing devices.

[0092] As shown in Figure 3(a), when external network element A is abnormal, after external interface device A is powered on, when the first detection cycle arrives, a heartbeat detection request message is sent to external network element A through all links with external network element A. At this time, external network element A is abnormal and cannot reply to the heartbeat detection response message.

[0093] If the external interface device A does not receive a heartbeat detection response message of a certain link of the external network element A within a preset time, the number of heartbeat detection failures of the certain link of the external network element A is increased by 1.

[0094] When the second detection cycle arrives, a heartbeat detection request message is sent to the external network element A through all links with the external network element A. If the external network element A recovers to normal at this time, the external network element A sends a heartbeat detection response message to the external interface device A through all links, and the external interface device A clears the number of heartbeat detection failures;

[0095] At this time, if the external network element A is still abnormal, the external network element A still cannot reply to the heartbeat detection response message.

[0096] If the external interface device A does not receive a heartbeat detection response message of a certain link of the external network element A within a preset time, the number of heartbeat detection failures of the certain link of the external network element A is increased by 1.

[0097] The subsequent detection cycles are similar.

[0098] When the number of heartbeat detection failures of a certain link of the external network element A is greater than or equal to the preset number of failures, it is determined that a certain link between the external interface device A and the external network element A is abnormal.

[0099] When the number of abnormal links in the links between the external network element A and the external interface device A is greater than or equal to the second preset threshold, it is determined that the external network element A is in the offline mode, and the external interface device A automatically enters the offline mode.

[0100] Since the external network element A and the N external interface devices A are all linked, the N external interface devices A automatically enter the offline mode.

[0101] After the external interface device A enters the offline mode, it no longer responds to the heartbeat detection request messages sent by the N message processing devices, but continues to send heartbeat detection request messages to the external network element A and the N message processing devices.

[0102] If the message processing module does not receive the heartbeat detection response message of the external interface device A within the preset time, the number of heartbeat detection failures of the external interface device A is increased by 1. If the number of heartbeat detection failures of the external interface device A is greater than or equal to the preset number of failures, it is determined that the link with the external interface device A is abnormal, and further determined that the external interface device A is in offline mode.

[0103] When the number of the external interface devices A in the offline mode among the N external interface devices A is greater than or equal to a third preset threshold, it is determined that the message processing module enters the offline mode.

[0104] Since the external interface device A establishes links with the N message processing devices, the N message processing devices automatically enter the offline mode.

[0105] After the message processing device enters the offline mode, it no longer responds to the heartbeat detection request messages sent by the N business logic processing devices and the N external interface devices B, but continues to send heartbeat detection request messages to the N external interface devices A, the N external interface devices B and the N business logic processing devices.

[0106] After the message processing device enters the offline mode, the N business logic processing devices and the N external interface devices B also automatically enter the offline mode.

[0107] After the N external interface devices A, the N external interface devices B, the N message processing devices and the N service logic processing devices all enter the offline mode, the SMSC system enters the offline mode.

[0108] As shown in Figure 3(b), after the SMSC system enters offline mode, if external network element A returns to normal, when external network element A receives the heartbeat detection request message sent by external interface device A through all links, it will reply with a heartbeat detection response message to external interface device A through all links.

[0109] When the number of links of the heartbeat detection response message received by the external interface device A from the external network element A is greater than or equal to the fourth preset threshold, it is determined that the external network element A is back online, and the external interface device A is also automatically back online.

[0110] Since the external network element A and the N external interface devices A are all linked, the N external interface devices A are automatically restored online.

[0111] After the external interface device A is restored online, the external interface device A resumes responding to the heartbeat detection request message of the message processing device, and the message processing device is also restored online.

[0112] After the message processing device is restored online, the business logic processing device and the external interface device B are also restored online.

[0113] Example 2

[0114] This example describes a method for internal devices in an SMSC system to automatically go online and offline due to a service logic processing device exception trigger.

[0115] like Figure 2 As shown, the execution process of SMSC system 1 and SMSC system 2 is the same, and this example takes SMSC system 1 as an example for description.

[0116] like Figure 2As shown, the SMSC system 1 includes: N external interface devices A deployed in N+1 load sharing mode, N external interface devices B deployed in N+1 load sharing mode, N message processing devices deployed in N+1 load sharing mode, and N business logic processing devices and operation and maintenance devices deployed in N+1 load sharing mode.

[0117] The operation and maintenance equipment establishes links with N external interface devices A, N external interface devices B, N message processing devices, and N business logic processing devices respectively. Each external interface device A establishes a link with external network element A and N message processing devices. Each external interface device B establishes a link with external network element B and N message processing devices. Each message processing device establishes a link with N external interface devices A, N external interface devices B, and N business logic processing devices. Each business logic processing device establishes a link with N message processing devices.

[0118] As shown in Figure 4(a), when the business logic processing device is abnormal, after the message processing device is powered on, when the first detection cycle arrives, it sends a heartbeat detection request message to the business logic processing device. At this time, the business logic processing device is abnormal and cannot reply with a heartbeat detection response message.

[0119] If the message processing device does not receive a heartbeat detection response message from the business logic processing device within a preset time, the number of heartbeat detection failures of the business logic processing device is increased by 1.

[0120] When the second detection cycle arrives, a heartbeat detection request message is sent to the business logic processing device. If the business logic processing device returns to normal at this time, the message processing device sends a heartbeat detection response message to the business logic processing device, and the message processing device clears the number of heartbeat detection failures;

[0121] At this time, if the business logic processing device is still abnormal, the business logic processing device still cannot reply to the heartbeat detection response message.

[0122] If the message processing device does not receive a heartbeat detection response message from the business logic processing device within a preset time, the number of heartbeat detection failures of the business logic processing device is increased by 1.

[0123] The subsequent detection cycles are similar.

[0124] When the number of heartbeat detection failures of the business logic processing device is greater than or equal to the preset number of failures, it is determined that the link between the business logic processing device and the message processing device is abnormal, and further determined that the business logic processing device is in offline mode.

[0125] When the number of the service logic processing devices in the offline mode among the N service logic processing devices is greater than or equal to a third preset threshold, the message processing module automatically enters the offline mode.

[0126] Since the business logic processing device and the N message processing devices are linked, the N message processing devices automatically enter the offline mode.

[0127] After the message processing device enters the offline mode, it no longer responds to the heartbeat detection request messages sent by N external interface devices A and N external interface devices B, but continues to send heartbeat detection request messages to N external interface devices A, N external interface devices B and N business logic processing devices.

[0128] After the message processing device enters the offline mode, the N external interface devices and the N external interface devices B also automatically enter the offline mode.

[0129] After the N external interface devices A, the N external interface devices B, the N message processing devices and the N service logic processing devices all enter the offline mode, the SMSC system enters the offline mode.

[0130] As shown in Figure 4(b), after the SMSC system enters offline mode, if the business logic processing device returns to normal, when the business logic processing device receives the heartbeat detection request message sent by the message processing device, it will reply with a heartbeat detection response message to the message processing device.

[0131] The message processing device receives the heartbeat detection response message sent by the business logic processing device and determines that the business logic processing device is back online.

[0132] When the number of the service logic processing devices that have resumed online among the N service logic processing devices is greater than or equal to a fifth preset threshold, the message processing device also automatically resumes online.

[0133] Since the business logic processing device and the N message processing devices are linked, the N message processing devices are automatically restored online.

[0134] After the message processing device is restored online, the message processing device resumes responding to the heartbeat detection request messages of the external interface device A and the external interface device B, and the external interface device A and the external interface device B are also restored online.
