In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, various implementations of the present application will be described in detail below in conjunction with the accompanying drawings. Those skilled in the art can understand that in various embodiments of the present application, many technical details are provided for readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in this application can also be realized.

The embodiment of the present application relates to a method for establishing a data connection, which is applied to a first network side device. The specific process is shown in FIG. 1 , including steps 101 to 103. The first network side device may be a connection management module, and may be deployed in an operator's core network. In this embodiment, the terminal needs to use a certain application, and establishes a data connection with the application server. At this time, the first network side device assigns data connection identifiers to the terminal and the application server respectively, sends the data connection identifiers of the application server to the terminal, and further synchronizes the data connection identifiers of the terminal and the application server to the second network side equipment. The process in Fig. 1 will be described in detail below.

Step 101, the first network-side device assigns data connection identifiers to the terminal and the application server respectively, and associates the assigned data connection identifiers with their respective Internet Protocol Addresses ("IP addresses").

In this embodiment, the terminal establishes a data connection with an application server, and before the data connection is established between the terminal and the application server, step 101 is performed, that is, assigning a data connection identifier to the terminal, and combining the assigned data connection identifier with the and associating with the IP address of the terminal; and assigning a data connection identifier to the application server, and associating the assigned data connection identifier with the IP address of the application server.

In some implementations, before the data connection is established between the terminal and the application server, the above step 101 includes: the terminal and the application server respectively apply for a data connection identifier, and the first network side device receives the terminal and the application server to register the data connection identifier identifier; and assigning data connection identifiers to the terminal and the application server respectively, and associating the assigned data connection identifiers with their respective IP addresses.

Step 102, the first network side device sends the data connection identifier of the application server to the terminal to enable the two parties to establish a data connection, and transmits data carrying the data connection identifiers of the terminal and the application server.

In this embodiment, since the terminal needs to establish a data connection with an application server, the first network side device needs to send the data connection identifier of the application server to the terminal, so that the terminal can send a data connection request to the application server, and then communicate with the application server. The application server establishes a data connection. In step 102, when the terminal needs to access an application, the first network side device sends the data connection identifier of the application server to the terminal. After the data connection is established between the terminal and the application server, the data transmitted by the terminal and the application server carries the data connection identifiers of the terminal and the application server.

Step 103, the first network-side device synchronizes the data connection identifiers of the terminal and the application server to the second network-side device, so that the second network-side device can identify the transmitted data according to the data connection identifiers of the terminal and the application server and process the data. Quality of Service (Quality of Service, referred to as "QoS") detection and/or QoS adjustment.

After the data connection is established between the terminal and the application server, if the second network side device wants to perform QoS detection and/or QoS adjustment on the data transmitted by the terminal and the application server, it needs to identify the transmission according to the data connection identifier of the terminal and the application server The data. In some implementations, the above step 103 includes: after detecting that the terminal establishes a data connection with the application server, the first network-side device synchronizes the data connection identifiers of the terminal and the application server to the second network-side device , for the second network side device to perform QoS detection and/or QoS adjustment on the data according to the data connection identifiers of both parties.

The first network-side device in this embodiment assigns data connection identifiers to the terminal and the application server respectively, and associates the assigned data connection identifiers with their respective IP addresses, so that the terminal and the application server can identify each other through the data connection. It does not need to re-query the IP address in order to establish a connection when the IP address changes, which shields the impact of frequent changes in the IP address on the establishment of the data connection. The first network-side device synchronizes the data connection identifiers of the terminal and the application server to the second network-side device. Even if the IP addresses of the terminal and the application server change frequently, the second network-side device can directly identify the transmission through the data connection identifier. and perform QoS detection and/or QoS adjustment on the data.

The embodiment of the present application also relates to a method for establishing a data connection, which is applied to a second network side device. The specific process is shown in FIG. 2 , including steps 201 to 203. The second network side device may be a packet detection and policy execution module, which may be used in the session management function (Session Management Function, referred to as "SMF"), user plane function (User Plane Function, referred to as "UPF") network in the operator's core network Upgrading and transformation on a meta-basic basis. In this embodiment, the terminal and the application server have established a data connection, and transmit data carrying the data connection identifiers of both parties. The second network-side device receives the data connection identifiers of the terminal and the application server sent by the first network-side device, identifies the data transmitted by both parties according to the data connection identifiers, and further performs QoS detection and/or QoS adjustment on the data. The process in Fig. 2 will be described in detail below.

In step 201, the second network side device receives the data connection identifiers of the terminal and the application server sent by the first network side device.

After the terminal establishes a data connection with the application server, the first network-side device sends the data connection identifier of the terminal and the application server to the second network-side device, and in step 201, the second network-side device receives the data connection identifier, and uses To identify the transmitted data and perform subsequent QoS detection and/or QoS adjustment on the data.

Step 202, the second network side device identifies the data transmitted by the terminal and the application server.

After the data connection is established between the terminal and the application server, the terminal and the application server transmit data carrying the data connection identifiers of both parties. In step 202, the second network side device identifies the data transmitted by the terminal and the application server through the data connection identifier.

Step 203, the second network side device performs QoS detection and/or QoS adjustment on the data.

In some implementations, after the second network side device identifies the data transmitted by the terminal and the application server through the data connection identifier, it performs QoS detection on the data. If the notification of the adjustment is notified, the QoS adjustment is performed on the data.

In a specific example, a mobile terminal accesses a video application, and after the mobile terminal establishes a data connection with the video application server, the first network-side device sends the data connection identifier between the mobile terminal and the video application server to the second network-side device symbol. The second network side device identifies the mobile terminal and the data transmitted by the video application server through the data connection identifier, and executes a corresponding QoS policy. When the video application server monitors that the QoS does not meet the video viewing requirements, the video application server carries the data connection identifiers of the mobile terminal and the video application server to request QoS adjustment to the third network side device, and the third network side device confirms the adjustment After the QoS adjustment, the QoS policy is updated to the second network side device to complete the QoS adjustment. The third network side device can be a policy management and open module, which can be upgraded and modified on the basis of a policy control function (Policy Control Function, "PCF") network element in the operator's core network.

A connection proxy module can also be set at the terminal and the application server, and the connection proxy module can be made into a protocol stack plug-in and installed on the terminal and the application server. When the terminal and the application are registered in the network, the respective connection agent modules apply for a data connection identifier from the first network side device.

Even if the IP address changes, the second network side device can directly identify the transmitted data through the data connection identifier and perform QoS detection and/or QoS adjustment on the data. In the case that the IP addresses of the terminal and the application server change frequently, the pressure of identifying data and performing QoS detection and/or QoS adjustment is greatly reduced.

The specific process is shown in FIG. 4 , including steps 401 to 403 . In this embodiment, the terminal needs to use a certain application, and establishes a data connection with the application server.

The specific process is shown in FIG. 5 , including steps 501 to 503. In this embodiment, the data connection has not been established between the terminal and the application server. Before the terminal establishes a data connection with the application server, the application server first applies for a data connection identifier from the first network-side device, and then establishes a data connection with the terminal for data transmission. After the application server and the terminal perform data transmission, apply to the third network side device for adjusting the QoS of the data. The flow in Fig. 5 will be described in detail below.

Here, the data should carry the data connection identifiers of the terminal and the application server, so that the network side device can subsequently identify the data and perform QoS detection and/or QoS adjustment on the data.

In step 503, the application server carries the data connection identifiers of both parties to apply to the third network side device for QoS adjustment.

After the terminal establishes a data connection with the application server for data transmission, if there is a need for QoS adjustment, the application server carries the data connection identifier between the terminal and the application server to apply to the third network side device for QoS adjustment.

In a specific example, when a mobile terminal accesses a mobile game application, after the mobile terminal establishes a data connection with the mobile game application server, when the mobile game application server detects that the QoS cannot meet the mobile game experience requirements, the mobile game application service The terminal carries the data connection identifiers of the mobile terminal and the mobile game application server to request the third network side device to perform QoS adjustment, such as increasing bandwidth.
