A data transmission method and device provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Based on the communication system shown in fig. 1, the network element group shown in fig. 2, and the terminal device of the android operating system shown in fig. 3, a data transmission method provided in an embodiment of the present invention, and fig. 4 shows a flowchart of a data transmission method provided in an embodiment of the present invention. As shown in fig. 4, the data transmission method provided in the embodiment of the present invention may include steps 201 to 205 described below.

Step 201, the terminal device sends target VOWIFI data to the target network element group.

In this embodiment of the present invention, the target network element group includes at least two first network elements, and each first network element is configured to process VOWIFI data.

In the embodiment of the invention, under the condition that the terminal equipment is connected with the WIFI network, the terminal equipment can send target VOWIFI data to the target network element group.

Optionally, in this embodiment of the present invention, the target network element group may be an N3IWF network element group, where the N3IWF network element group includes at least two N3IWF network elements.

Optionally, in the embodiment of the present invention, an N3IWF network element group may be constructed on a network side (for example, a core network side) in advance, and each N3IWF network element in the N3IWF network element group has a synergistic effect, and data transmission may be performed between each N3IWF network element.

It should be noted that, the target network element group may be a device having a processing function, and the number of the first network elements included in the target network element group is determined by the operator network.

Optionally, in the embodiment of the present invention, when the user triggers the terminal device to start the VOWIFI function, the terminal device may send target VOWIFI data to the target network element group to perform VOWIFI registration or service interaction, so as to implement functions such as making a call, receiving a call, or making a video call.

It should be noted that the target VOWIFI data may be understood as signaling (e.g., registration signaling) or data (e.g., service data) sent by the terminal device to a network element in the VOWIFI network architecture.

Step 202, the target network element group receives the target VOWIFI data sent by the terminal equipment.

Optionally, in this embodiment of the present invention, the first target network element in the target network element group is configured to process target VOWIFI data. The first target network element is a first network element in the target network element group, which meets a preset condition, where the preset condition includes at least one of: the load ratio is smaller than a first preset threshold, the throughput is larger than a second preset threshold, and the number of connected terminal devices is smaller than a third preset threshold.

It is to be understood that the first target network element may include at least one first network element satisfying a preset condition.

Optionally, in this embodiment of the present invention, the first target network element may be a first network element with a smallest load ratio in the target network element group; or, the first target network element may be a first network element with the largest throughput in the target network element group; or, the first target network element may be a first network element with the smallest number of terminal devices connected in the target network element group.

And 203, processing the target VOWIFI data by the target network element group.

Optionally, in the embodiment of the present invention, as shown in fig. 5 in combination with fig. 4, the step 203 may be specifically implemented by a step 203a and a step 203b described below.

Step 203a, the target network element group determines a first target network element in the target network element group.

In this embodiment of the present invention, the first target network element is a first network element in a target network element group, where the first target network element meets a preset condition, where the preset condition includes at least one of: the load ratio is smaller than a first preset threshold, the throughput is larger than a second preset threshold, and the number of connected terminal devices is smaller than a third preset threshold.

It is to be understood that, after receiving the target VOWIFI data, the target network element group may determine, according to a usage (for example, a load ratio, a throughput, a number of connected terminal devices, and the like) of each of the at least two first network elements, a first target network element from the at least two first network elements.

The load ratio may be understood as: a ratio of a total number of signaling and data currently being processed by the network element to a total number of signaling and data that can be concurrently processed in total.

And 203b, the target network element group distributes target VOWIFI data to the second target network element, and the second target network element processes the target VOWIFI data.

In this embodiment of the present invention, the second target network element is one of the first target network elements.

It should be noted that, in a case that the first target network element includes multiple first network elements, the target network element group may randomly select one first network element (i.e., the second target network element) from the first target network elements, and allocate the target VOWIFI data to the one first network element.

Optionally, in this embodiment of the present invention, the target network element group may also randomly select one first network element from the at least two first network elements, and allocate the target VOWIFI data to the one first network element.

Optionally, in the embodiment of the present invention, the second target network element may perform decapsulation, encapsulation, service splitting, and other processing on the target VOWIFI data.

In the embodiment of the invention, the target network element group can preferentially allocate the target VOWIFI data to the first network element meeting the preset condition for processing, so as to improve the possibility and the success rate of processing the target VOWIFI data.

Optionally, in the embodiment of the present invention, after the step 203b, the data transmission method provided in the embodiment of the present invention may further include the following step 301.

Step 301, if the second target network element is abnormal in processing the target VOWIFI data, processing the target VOWIFI data by the target network element group through the other first network elements.

In this embodiment of the present invention, the other first network elements are first network elements in the target network element group except for the first target network element.

Optionally, in this embodiment of the present invention, when the second target network element fails to process the target VOWIFI data or does not process the target VOWIFI data, the second target network element may send the target VOWIFI data to another first network element, so that the other first network element processes the target VOWIFI data.

Optionally, in this embodiment of the present invention, the second target network element may preferentially send the target VOWIFI data to the first network element that meets the preset condition in the other first network elements; or, the second target network element may randomly select one first network element from other first network elements, and send the target VOWIFI data to the one first network element.

It can be understood that data interaction can be performed between at least two first network elements in the target network element group, when one first network element in the at least two first network elements has an abnormality in processing the target VOWIFI data, the one first network element can send the target VOWIFI data to one first network element in another first network element for processing, and if one first network element in the another first network element has an abnormality in processing the target VOWIFI data, the one first network element continues to send the target VOWIFI data to a different first network element until the processing of the target VOWIFI data is completed.

For example, it is assumed that the target network element group is an N3IWF network element group, and the N3IWF network element group includes three N3IWF network elements, i.e., an N3IWF network element 1 with a duty ratio of 10%, an N3IWF network element 2 with a duty ratio of 50%, and an N3IWF network element 3 with a duty ratio of 50%; when the N3IWF network element group receives the target VOWIFI data, the N3IWF network element group may preferentially allocate the target VOWIFI data to the N3IWF network element 1 for processing, if the N3IWF network element 1 is abnormal in processing the target VOWIFI data, the target network element group may randomly allocate the target VOWIFI data to one N3IWF network element (for example, the N3IWF network element 2), and if the N3IWF network element 2 is also abnormal in processing the target VOWIFI data, the target network element group may continue to allocate the target VOWIFI data to the N3IWF network element 3 for processing.

In the embodiment of the invention, when the target VOWIFI data processed by the second target network element is abnormal, the target VOWIFI data can be processed by other first network elements, so that the possibility and the success rate of processing the target VOWIFI data can be improved.

And step 204, the target network element group sends the first data to the terminal equipment.

In the embodiment of the present invention, the first data is used to indicate a processing result of the target VOWIFI data.

Optionally, in this embodiment of the present invention, the first data is used to indicate a processing result of the target VOWIFI data by the second target network element, where the second target network element is one of the first target network elements.

Optionally, in this embodiment of the present invention, the first data is used to indicate a processing result of the second network element on the second data, the second data is used to indicate a processing result of the second target network element on the target VOWIFI data, and the second network element is a network element other than the target network element group.

Optionally, in this embodiment of the present invention, the first data may be used to indicate that an exception occurs in processing the target VOWIFI data.

Optionally, in an embodiment of the present invention, in the case of executing the step 301, the step 204 may be specifically implemented by a step 204a described below.

And step 204a, if the VOWIFI data processed by the other first network elements are abnormal, the target network element group sends first data to the terminal equipment.

In this embodiment of the present invention, the first data in step 204a may be used to indicate that the processing of the target VOWIFI data by other first network elements is abnormal.

It can be understood that, under the condition that all the first network elements in the target network element group are abnormal in processing the target VOWIFI data, the target network element group may send the first data to the terminal device, so as to indicate to the terminal device that all the first network elements in the target network element group are abnormal in processing the target VOWIFI data.

Step 205, the terminal device receives the first data sent by the target tuple.

Optionally, in this embodiment of the present invention, if the first data received by the terminal device is used to indicate that all first network elements in the target network element group process the target VOWIFI data and an abnormality occurs, the terminal device may send the target VOWIFI data to other first network element groups (for example, other N3IWF network elements) again, so as to retry the VOWIFI service.

The embodiment of the invention provides a data transmission method, wherein terminal equipment can send target VOWIFI data to a target network element group (the target network element group comprises at least two first network elements), so that the network elements in the target network element group process the target VOWIFI data. After the terminal device sends the target VOWIFI data to the target network element group, any first network element in the target network element group can process the target VOWIFI data, namely when one first network element processes the target VOWIFI data abnormally, the target VOWIFI data can be processed by other first network elements, so that the possibility and success rate of processing the target VOWIFI data can be improved, and the performance of data transmission can be improved.

Optionally, in the embodiment of the present invention, with reference to fig. 5, as shown in fig. 6, after the step 203b, the data transmission method provided in the embodiment of the present invention may further include the following steps 401 to 404.

Step 401, the target network element group sends the second data to the second network element.

And step 402, the second network element receives second data sent by the target network element group and processes the second data.

In this embodiment of the present invention, the second data is used to indicate a processing result of the second target network element on the target VOWIFI data, and the second network element is a network element other than the target network element group.

Optionally, in this embodiment of the present invention, the second network element may be a network element in a core network (e.g., a 5G core network) except for the target network element group.

Optionally, in this embodiment of the present invention, the second network element may perform decapsulation, encapsulation, service offloading, and other processing on the second data.

Step 403, the second network element sends the first data to the target network element group.

Step 404, the target network element group receives the first data sent by the second network element.

In this embodiment of the present invention, the first data in step 403 and step 404 is used to indicate a processing result of the second network element on the second data. That is, the first data is obtained after the second network element processes the second data.

It can be understood that, after the second target network element processes the target VOWIFI data, the target network element group may send a processing result of the second target network element on the target VOWIFI data to the second network element, so that the second network element further processes the processing result.

It should be noted that, in the embodiment of the present invention, the terminal device performs data interaction (for example, target VOWIFI data, first data, and the like) with the target network element group through the base station.
