It should be noted that Figure 1This is merely one example of a particular embodiment and is intended to illustrate the types of components that may be present in the above-described computer device (or electronic device).

[0037] Under the above operating environment, this application provides the following Figure 2 It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0038] Figure 2 is a flow chart of an information transmission method according to an embodiment of the present application, which is applicable to any gateway instance in a gateway cluster, such as Figure 2 As shown, the method comprises the following steps:

[0039] Step S202, receiving target information;

[0040] Step S204, determining the information identifier of the target information, and associating the first device identification information, the second device identification information and the information identifier, wherein the first device identification information is the device identification information of the first information device that sends the target information, and the second device identification information is the device identification information of the second information device that receives the target information;

[0041] Step S206, when the associated information of the target information is received, determining the device identification information of the target information device receiving the associated information according to the information identifier, wherein the associated information carries the information identifier, and the target information device is the first information device or the second information device;

[0042] Step S208: sending the associated information to the target information device according to the device identification information of the target information device.

[0043] The information transmission method described in steps S202 to S208 can be applied to a 5G message system. When the message gateway in the 5G message system is deployed on a gateway cluster, message forwarding and transmission are achieved through the gateway cluster. The information transmission method can be used to provide an accurate routing selection method for delivering message receipts and message withdrawals.

[0044] In step S204 of the information transmission method, the first device identification information, the second device identification information and the information identifier are associated, such as Figure 3 The flowchart shown specifically includes the following steps:

[0045] Step S302, determining first device identification information of a first information device;

[0046] Step S304, determining the second information device according to a preset rule, and obtaining the second device identification information of the second information device;

[0047] Step S306: store the information identifier in the target database, and store the association relationship between the first device identification information, the second device identification information and the information identifier.

[0048] In step S302 to step S306, the first device identification information of the target information is determined, the target information carries an information identifier, the information identifier can be represented by Message ID, the first device identification information at least includes the device identification, device address, etc. of the first information device, the second device identification information at least includes the device identification, device address, etc. of the second information device, and the second information device receiving the target information is determined according to the preset rules, the preset rules can be the original business routing rules of the gateway instance, because there are multiple gateway instances in the gateway cluster, the multiple gateway instances share a set of northbound interface device configuration information, including the device identification, device address, etc. of the northbound interface device, and the multiple gateway instances share a set of southbound interface device configuration information, including the device identification, device address, etc. of the southbound interface device. Multiple gateway instances share a key-value-based memory database, which is the target database in the embodiment of the present application, and can quickly save and obtain related information according to the input key value.

[0049] For example, when the gateway instance receives target information forwarded from a northbound interface device, the southbound interface device is selected through routing rules, and the target information is sent to the southbound interface device. In this case, the first information device is a northbound interface device, and the first device identification information includes at least information such as the device identification and device address of the northbound interface device; the second information device is a southbound interface device, and the second device identification information includes at least information such as the device identification and device address of the southbound interface device; in another optional embodiment, for example, when the gateway receives target information forwarded from a southbound interface, the northbound interface device is selected through routing rules, and the target information is sent to the northbound interface device. In this case, the first information device is a southbound interface device, and the first device identification information includes at least information such as the device identification and device address of the southbound interface device; the second information device is a northbound interface device, and the second device identification information includes at least information such as the device identification and device address of the northbound interface device.

[0050] The second information device associated with the first information device is determined by preset rules, so that the first device identification information, the second device identification information and the information identifier carried in the target information are associated, and the association relationship is stored in the target database, so as to facilitate the determination of the device identification information of the receiving target information when forwarding the target information.

[0051] In step S206 of the information transmission method, the device identification information of the target information device receiving the associated information is determined according to the information identifier, such as Figure 4 The flowchart shown specifically includes the following steps:

[0052] Step S402, when the associated information is the receipt information of the target information, obtaining the information identifier of the target information carried in the receipt information;

[0053] Step S404: According to the information identifier, query the target database for the first device identification information associated with the information identifier, and determine that the first information device corresponding to the first device identification information is the target information device.

[0054] In step S402 to step S404, after the target information is sent to the second information device, the second information device needs to send a receipt information of the target information. When the gateway instance in the gateway cluster receives the receipt information from the second information device forwarded by the load balancing device, the gateway instance obtains the information identifier in the receipt information, that is, the Message ID. It should be noted that the information identifier carried in the target information and the information identifier carried in the receipt information of the target information are the same information identifier, both represented by Message ID. The source identifier of the target information associated with the Message ID is searched in the target database. The source identifier is the first device identification information of the first information device, that is, the device identification information corresponding to the device sending the target information. The first information device is determined as the target information device, and the receipt information of the target information is returned to the first information device, completing the information transmission once.

[0055] In step S206 of the information transmission method, the device identification information of the target information device receiving the associated information is determined according to the information identifier, such as Figure 5 The flowchart shown specifically includes the following steps:

[0056] Step S502, when the associated information is the withdrawal instruction information of the target information, obtaining the information identifier of the target information carried in the withdrawal instruction information;

[0057] Step S504: According to the information identifier, query the target database for the second device identification information associated with the information identifier, and determine that the second information device corresponding to the second device identification information is the target information device.

[0058] In step S502 to step S504, after the target information is sent to the second information device and before the second information device sends the receipt information of the target information, the first information device that sent the target information sends the withdrawal instruction information of the target information. When the gateway instance in the gateway cluster receives the withdrawal instruction information from the first information device forwarded by the load balancing device, the gateway instance obtains the information identifier in the withdrawal instruction information, that is, the Message ID. It should be noted that the information identifier carried in the target information is the same as the information identifier carried in the withdrawal instruction information of the target information, and both are represented by Message ID. The target database is searched for the destination identifier of the target information associated with the Message ID. The destination identifier is the second device identification information of the second information device, that is, the device identification information corresponding to the device that needs to receive the withdrawal instruction information of the target information. The second information device is determined as the target information device, thereby sending the withdrawal instruction information of the target information to the second information device.

[0059] In step S202 of the information transmission method, before receiving the target information, Figure 6 As shown in the flowchart, the information transmission method further includes the following steps:

[0060] Step S602, determining the load status of each gateway in the gateway cluster;

[0061] Step S604: determining a first target gateway instance for receiving target information from the gateway cluster according to the load status.

[0062] In steps S602 to S604, before receiving the target information, the load balancing device in the gateway cluster needs to first determine the load status of each gateway instance in the gateway cluster. When all gateway instances are not in an idle state, it is necessary to wait until there is a gateway instance in an idle state, and then randomly select a gateway instance from the idle gateway instances as the first target gateway instance to receive the target information; in another optional embodiment, if the load balancing device in the gateway cluster determines that there is an idle gateway instance in the cluster, there is no need to wait, and directly randomly select a gateway instance from the idle gateway instances as the first target gateway instance to receive the target information.

[0063] In step S206 of the information transmission method, before receiving the associated information of the target information, such as Figure 7 As shown in the flowchart, the information transmission method further includes the following steps:

[0064] Step S702, determining the load status of each gateway in the gateway cluster;

[0065] Step S704: determining, according to the load status, from the gateway cluster, a second target gateway instance for receiving associated information of the target information.

[0066] In steps S702 to S704, after the target information is sent to the target information device and before the associated information of the target information is received, the associated information includes the receipt information of the target information or the withdrawal instruction information of the target information. It is necessary to judge the load status of each gateway instance in the gateway cluster again. When the load balancing device in the gateway cluster determines that all gateway instances in the gateway cluster are not in an idle state, it is necessary to wait until there is a gateway instance in an idle state, and then randomly select a gateway instance from the idle gateway instances as the second target gateway instance for receiving the associated information of the target information; in another optional embodiment, if the load balancing device in the gateway cluster determines that there is an idle gateway instance in the cluster, there is no need to wait, and directly randomly select a gateway instance from the idle gateway instances as the second target gateway instance for receiving the associated information of the target information.

[0067] In the information transmission method, the target information is uplink information or downlink information, wherein: when the target information is downlink information, the first information device is a northbound interface device, and the second information device is a southbound interface device; when the target information is uplink information, the first information device is a southbound interface device, and the second information device is a northbound interface device.

[0068] Through the above steps, the first device identifier, the second device identifier and the information identifier are associated, and when the associated information of the target information is received, the device identifier information of the target information device receiving the associated information is determined based on the information identifier, thereby achieving the purpose of sending the associated information to the target information device, thereby realizing the technical effect of information transmission, and further solving the technical problem of the load balancing device not identifying the business content, resulting in routing selection of message receipts or message withdrawals.

[0069] The information transmission method provided in the embodiment of the present application can be closely integrated with the 5G message transmission scenario, and is suitable for the cluster deployment of 5G message gateways. At the same time, the load balancing distribution device and shared memory can be implemented using common open source technologies in the industry, reducing development costs.

[0073] A retrieval module 806 is used to determine the device identification information of the target information device receiving the associated information according to the information identifier when the associated information of the target information is received, wherein the associated information carries the information identifier, and the target information device is the first information device or the second information device;
