Example one

FIG. 9 is a schematic diagram showing an interaction flow of an information processing method according to an embodiment of the present invention; as shown in fig. 9, the method includes:

Step 901: the AF sends first configuration information to the UDM via the NEF, wherein the first configuration information may include 5G VN group information including general public user identity (GPSI, generic Public Subscription Identifier) of UEs within the 5G VN group, DNN, single network slice selection assistance information (S-nsai, single Network Slice Selection Assistance Information) and service area (denoted as first service area).

Here, the first configuration information corresponds to the first information in the foregoing embodiment.

Step 902: the OAM device configures the AMF with second configuration information, which may include a 5G VN group service range (denoted as a second service range), the 5G VN group service range being a service range of the LADN.

Here, the second configuration information corresponds to tenth information in the foregoing embodiment.

Step 903: the UE initiates a registration request for requesting device registration.

Step 904: after receiving the registration request, the AMF interacts with the UDM, and obtains first subscription data (corresponding to the first data) of the UE from the UDM, where the obtained data includes 5G VN group DNN (i.e. 5G LADN DNN), and a service range (first service range) of the 5G LADN DNN.

Step 905: the AMF sends the first subscription data to the UE, including the 5G VN group DNN (i.e. 5G LADN DNN) and the service range (third service range).

Here, the AMF obtains a first service range configured by the AF and a second service range configured by the OAM equipment, compares the first service range and the second service range, and determines a third service range. For example, if the first service range and the second service range are the same, the determined third service range may be the same as the first service range and the second service range. If the first service range and the second service range are different, the third service range may be equal to the smaller service range of the first service range and the second service range.

Step 906: when the UE is in a 5G VN group (i.e. 5G LADN) service range (third service range), the UE sends a session establishment request for requesting establishment of a 5G VN group session.

Optionally, the session establishment request may include DNN and/or S-NSSAI requested by the UE.

In this example, the UE determines whether to initiate a session establishment request based on the obtained third service scope. The UE acquires location information of the UE and determines whether the location information of the UE is within a third service range; when the position information of the UE is determined to be in the third service range, the UE sends a session establishment request; accordingly, when it is determined that the location information of the UE is not within the third service range, the UE does not transmit a session establishment request.

Here, the session establishment request corresponds to the twelfth information in the foregoing embodiment.

Step 907: the AMF sends a session establishment request to the SMF, wherein the session establishment request can comprise DNN and/or S-NSSAI requested by the UE; optionally, the session establishment request further includes indication information that the UE is in a 5G LADN service range (i.e., a service range of the 5G VN group, i.e., a third service range).

Here, the session establishment request corresponds to the sixth information in the foregoing embodiment.

Step 908: the SMF interacts with the UDM to obtain second subscription data (corresponding to the second data) of the UE from the UDM, where the obtained data includes 5G VN DNN, slice information (e.g. S-nsai), 5G VN group information (including the first service range).

Step 909: the SMF establishes a 5G VN group session.

Step 910: the SMF initiates an N4session setup (N4 session establishment) or an N4session update (N4 session update) to the UPF for configuring or updating the user plane communication of the related 5G VN group or 5G lan service.

Here, the above-described N4session establishment (N4 session establishment) or N4session update (N4 session update) corresponds to the eighth information in the above-described embodiment.

Example two

FIG. 10 is a second schematic diagram of an interaction flow of an information processing method according to an embodiment of the present invention; as shown in fig. 10, the method includes:

Step 1001: the AF sends first configuration information to the UDM via the NEF, wherein the first configuration information may include 5G VN group information including general public user identity (GPSI, generic Public Subscription Identifier) of UEs within the 5G VN group, DNN, single network slice selection assistance information (S-nsai, single Network Slice Selection Assistance Information) and service area (denoted as first service area).

Step 1002: the UE sends a session establishment request for requesting establishment of a 5G VN group session.

Here, the UE-initiated session establishment request corresponds to the twelfth information in the above-described embodiment.

Step 1003: the AMF sends a session establishment request to the SMF, where the session establishment request may include DNN and/or S-nsai requested by the UE, and the session establishment request further carries location information (denoted as first location information) of the UE.

Step 1004: the SMF interacts with the UDM to obtain second subscription data (corresponding to the second data) of the UE from the UDM, where the obtained data includes 5G VN DNN, slice information (e.g. S-nsai), 5G VN group information (including the first service range).

Step 1005: the SMF subscribes to the AMF for the UE location.

Step 1006: the SMF determines whether the location information (first location information) of the UE is in a 5G VN group service range (first service range), and establishes a 5G VN group session if the first location information is in the first service range.

Step 1007: the SMF initiates an N4session setup (N4 session establishment) or an N4session update (N4 session update) to the UPF for configuring or updating the user plane communication of the related 5G VN group or 5G lan service.

Step 1008: when the UE moves out of the first service range, the AMF transmits location information (second location information) of the UE to the SMF.

Step 1009: the SMF determines whether or not the location information (second location information) of the UE is within the 5G VN group service range (first service range), and updates or deletes the 5G VN group session if the second location information is not within the 5G VN group service range (first service range).

Step 1010: the SMF initiates an N4session release (N4 session release) or an N4session update (update) to the UPF to delete or update the user plane traffic of the associated 5G VN group or 5G lan service.

Here, deleting or updating the user plane traffic of the associated 5G VN group or 5G local area network service may include deleting or updating local forwarding information on the UPF and/or deleting or updating the N19 tunnel on the UPF.

According to the technical scheme provided by the embodiment of the invention, the first service range is configured into the second network equipment through the second network equipment, so that the establishment of the 5G virtual network group session based on the first service range is realized, and the dynamic joining of the terminal into the 5G virtual network group and the intra-group communication are realized.

In the real demand, the terminal dynamically joins the 5G VN group and realizes direct communication in the group under the condition of a specific location, which is a real demand. As in a plant, terminals are required to dynamically register terminals within the plant for access to the plant-specific 5G VN group and to enable features of the 5G VN group such as supporting direct communication between terminals. When the terminal moves out of the factory, the corresponding protocol data unit (PDU, protocol Data Unit) session is released, or the session is updated. Therefore, the embodiment of the invention realizes that the terminals in the scene such as the like dynamically join the 5G virtual network group and realize the intra-group communication.
