s202, interaction is carried out between the original session management network element and the unified data management network element so as to obtain first subscription management subscription information associated with a first data network name.
The session management network element (Session Management Function, SMF) is configured to implement session management functions in the 5G network, and is responsible for establishing, maintaining, and terminating session connection of a User Equipment (UE), and processing User data distribution and forwarding requests. The unified data management network element (Unified Data Management, UDM) is used for implementing a unified data management function in the 5G network, and is responsible for storing and managing user data and policy information about subscribers. The data network name (Data Network Name, DNN) is an identifier in the 5G network identifying different service types and applications, which defines the network and services to which the user equipment needs to be connected, such as the internet or the internet of things. The user equipment refers to a device connected to the 5G network. Subscription management (Subscription Management, SM) subscription information refers to subscription data related to user equipment, including authentication, network access rights, service subscription, security policies, etc. This information is critical to establishing the session channel. For example, the authentication and access rights information provided by the SM subscription information is used to verify the validity of the user equipment and to confirm whether it has the right to establish the session channel. The configuration of related security policies in SM subscription information, such as encryption algorithm, security parameters, etc., is used to ensure the security of session channels and to protect the confidentiality of user data.

Different preset parameter values in the first subscription management subscription information may correspond to different second data network names. For example, the second data network name may include any one of DNN2 and DNN3, with DNN1 being redirected to DNN2 when the parameter value in the subscription management subscription information is 100 and to DNN3 when the parameter value is 110.
In some embodiments, the original session management network element may determine, based on the first subscription management subscription information, whether the user device is entitled to establish a session channel associated with the first data network name; when the user equipment has the right to establish a session channel associated with the first data network name, judging whether the first subscription management subscription information comprises a preset parameter value or not.

It will be appreciated that the established session channel is associated with both the first data network name and the second data network name.
In some embodiments, the original session management network element may request the anchor session management network element to establish a session channel associated with the second data network name. The anchor session management network element may interact with the unified data management network element to obtain second subscription management subscription information associated with the second data name, and the anchor session management network element may establish a session channel based on the second subscription management subscription information.
S208, the session information carried by the session channel is acquired through the original session management network element, and the session information is mapped to the first data network name or the second data network name.
The original session management network element receives data sent by the user equipment by acquiring a session message carried by the session channel. It will be appreciated that when the user equipment sends a session message via the session channel, the session message described above will be transmitted to the original session management network element. When the session message of the user equipment is acquired, the mapped target data network name is determined according to the content of the session message. The target data network name may include any one of a first data network name and a second data network name. And transmitting the session message to the target data network corresponding to the target data network name through the original session management network element. It will be appreciated that different DNN values may direct session messages to different target data networks, such as the internet, the internet of things, or an enterprise VPN.

The access mobility management network element may then send a notification of the registration completion to the user equipment. The unified data management network element may store the first subscription management subscription information and the second subscription management subscription information.
In some embodiments, the access mobility management element may request that the unified data management element make a subscription for the user device for the first data network name and the second data network name. The unified data management network element can respond to the request of accessing the mobile management network element, sign up a plurality of data network names for the user equipment at the same time, and feed back sign up information of the first data network name and the second data network name to the access mobile management network element. The access mobility management element may determine that registration is complete upon obtaining subscription information for the first data network name and the second data network name. It is understood that the subscription information for the first data network name and the second data network name may include first subscription management subscription information and second subscription management subscription information.

The first session establishment request is for requesting establishment of a session channel associated with the first data network name. The access mobility management network element may forward the first session establishment request to the original session management network element. The original session management network element may obtain, from the unified data management network element, first subscription management subscription information associated with the first data network name in response to the first session establishment request.
In this embodiment, a first session establishment request for a first data network name is sent to an original session management network element by accessing the mobility management network element; the original session management network element interacts with the unified data management network element according to the first session establishment request to acquire first subscription management subscription information associated with the first data network name, and session establishment of a plurality of data network names can be completed based on preset parameter values in the first subscription management subscription information, URSP is not required to be supported by user equipment, and adaptability is improved.
In some embodiments, the first subscription management subscription information includes parameter values under at least two parameter items; in the case that the first subscription management subscription information includes a preset parameter value, redirecting, by the original session management network element, to the second data network name, including: determining a target parameter value under a target parameter item in the first subscription management subscription information through an original session management network element; and under the condition that the target parameter value is a preset parameter value, redirecting to the second data network name through the original session management network element.
Wherein the target parameter item may be a charging characteristic item (Charging Characteristics, CC). In the subscription information, charging Characteristics refers to an attribute related to charging of the user equipment, and describes information such as a charging policy, rate calculation, and charging period. The unified data management network element has the capability to set Charging Characteristics, so that session establishment of the first data network name can be redirected to other different data network names by the unified data management network element setting different parameter values under the charging characteristic item.
For example, the original session management network element may obtain the target parameter value under the target parameter item in the first subscription management subscription information. And redirecting the original session management network element to the second data network name corresponding to the target parameter value under the condition that the target parameter value is the preset parameter value. It is understood that the preset parameter values may include at least one. For example, the preset parameter values may include 110 and 100, with the target parameter value being 110 redirected to DNN3 and the target parameter value being 100 redirected to DNN2.
In this embodiment, a target parameter value under a target parameter item in the first subscription management subscription information is determined by an original session management network element; under the condition that the target parameter value is a preset parameter value, the original session management network element redirects the target parameter value to the second data network name, so that a session channel which is simultaneously associated with the second data network name and the first data network name can be established subsequently, and the adaptability is improved.
In some embodiments, establishing the session channel by interacting the original session management network element with the anchor session management network element comprises: transmitting a second session establishment request for a second data network name to the anchor session management network element through the original session management network element; interacting with the unified data management network element through the anchor point session management network element to acquire second subscription management subscription information associated with a second data network name; and establishing a session channel based on the second subscription management subscription information.

After receiving the request of the anchor point session management network element, the unified data management network element verifies the identity and authority of the anchor point session management network element, and under the condition that verification is passed, second subscription management subscription information associated with the second data network name is searched and sent to the anchor point session management network element as a response.
In some embodiments, the anchor session management network element may determine whether the user device is entitled to establish a session channel associated with the second data network name based on the second subscription management subscription information. When the user device has the right to establish a session channel associated with the second data network name, the anchor session management network element may establish the session channel. It can be appreciated that in the session channel, by using the original session management network element as an intermediate session management network element, it is possible to implement that one session channel associates the first data network name and the second data network name at the same time.

In some embodiments, the user equipment may send a session message to the original session management network element over the session channel. The original session management network element may map the session message to a target data network name and transmit the session message to a target data network corresponding to the target data network name.
In this embodiment, after the session channel is established, a notification of success of session channel establishment associated with the first data network name is sent to the access mobility management network element through the original session management network element; the user equipment can timely sense the established session channel by accessing the mobile management network element to forward the notification to the user equipment, and then conveniently access the first target data network and the second target data network through one session channel.
In some embodiments, the first data network name refers to a data network name used by the user equipment to connect to the public network; the second data network name refers to a data network name used by the user device to connect to the private network.
The network session processing method provided by the embodiment of the application can be applied to a dual-domain private network scene. The user equipment typically initiates session establishment using a generic DNN, and to avoid retrofitting the user equipment, the generic data network name is taken as the first data network name and the private data network name is taken as the second data network name. Furthermore, when the user equipment initiates the session establishment by using the universal DNN, the original session management network element redirects the session establishment of the universal DNN to other different special DNNs by using different preset parameter values associated with the universal DNN. For example, cc=100 corresponds to the dedicated DNN2, cc=110 corresponds to the dedicated DNN3. The original session management network element selects an anchor session management network element according to the redirected dedicated DNN, and sends a session establishment request of the redirected dedicated DNN to the anchor session management network element as an intermediate session management network element, and completes the subsequent flow.
