Abstract
The embodiment of the invention provides a method, equipment and a system for configuring an IP address, wherein the method for configuring the IP address is applied to a Unified Data Management (UDM) device, and comprises the following steps: and acquiring an IP address configured for a 5G virtual network group by a third-party function AF through a network open function NEF, wherein the 5G virtual network group comprises at least one terminal, and one terminal corresponds to one IP address. The scheme of the invention realizes that the appointed IP address can be distributed to the UE according to the AF requirement, and a third party is not required to build a DHCP server.
Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, a device, and a system for configuring an IP address.
Background
In the prior art, when a terminal establishes a PDU (Protocol Data Unit) Session, there are two ways to allocate IP addresses, one is that SMF (Session Management Function) is dynamically allocated to the terminal, and SMF maintains a UE address pool; the second is DHCP (Dynamic Host configuration Protocol) allocation, that is, after the PDU session is established, the UE initiates a DHCP allocation address request, and forwards the DHCP allocation address request to the SMF via the UPF (User Port Function), and the SMF forwards the DHCP allocation address request to the DHCP server (Dynamic Host configuration Protocol server) to obtain an externally allocated IP address.
Currently, there are some scenarios in 5G that require a third party to specify a fixed IP address segment for its access terminal. The address field may be a private network address field, such as 192.168. xx.xx. Then the first allocation is not supported because the SMF maintains address fields that are planned by the operator. The second way of distributing DHCP requires a third party DN (Data Network) to establish a DHCP server, and the SMF needs to communicate with the DHCP server. In the current network of the operator, the SMF is not supported to interwork with the third party DHCP.

Optionally, the configuration information may further carry at least one of a GPSI (general Public Subscription Identifier), a data network name, slice auxiliary selection information, and an external group ID of the terminal in the 5G virtual network.
In an optional embodiment of the present invention, the method may further include:
and step 12, when receiving a protocol data unit PDU session initiated by a terminal through a mobile management function AMF and a session management function SMF, sending the IP address to the terminal through the SMF and the AMF.

step 122, sending a response message of the request for obtaining subscription information to the SMF, where the response message carries the IP address, and sending the response message to the terminal through the AMF and the RAN.
Optionally, the IP address is a private network IP address configured by the third party function AF, and may also be a public network IP address. The IP address in the embodiment of the present invention may be an IPv4 address or an IPv6 prefix address.
In an optional embodiment of the present invention, the method may further include:
and step 13, the terminal transmits data with the third-party Data Network (DN) through a tunnel established between the UPF (user port function) and the DN. The tunnel may be a VXLAN (virtual extensible local area network) tunnel or an N6 tunnel.
The implementation of the above embodiment is further described below with reference to fig. 2:
step 1, the AF calls an interface of the NEF, and configures GPSI (generic public subscription identifier), 5GVN DNN (Data Network Name), slice auxiliary selection information, external group ID, and one segment or a designated IP address of a UE member in a group of 5G VNs to the UDM.
Step 2, NEF maps the external group ID to the internal group ID, and writes the information provided by other AF into UDM;
step 3, the UDM replies response information to the NEF;
step 4, the NEF replies response information to the AF;
step 5, UE initiates PDU conversation to AMF to establish the request;
step 6, the AMF calls PDU session establishment service of the SMF;
step 7, SMF removes UDM to obtain signing information; the SMF acquires subscription information of the UE and subscription information of the 5G VN group according to the SUPI (subscription permanent identifier) number of the UE, wherein the subscription information comprises one of an IP address or a segment of IP address assigned to the UE.
Step 8, the UDM replies a response message to the SMF, including the IP address configured to the UE.

The 5G VN group data includes one of an IP address or a segment of an IP address assigned to the UE (identified in GPSI) within the 5GVN group. These IP addresses may be private network IP addresses specified by the AF.
When a UE initiates a PDU session setup with a 5G VN DNN, the UDM will detect that the UE is one UE in the 5G VN group and assign the UE a specified IP address.
Furthermore, when the IP address specified by the third-party AF for the UE is a private IP address, a tunnel needs to be established between the UPF and the DN of the third party to ensure data routing, so as to ensure that the data packet can be correctly transmitted to the specified DN of the third party. The tunnel establishment may be independent of the PDU session establishment for the UE, and may be a 5G VN group-granular tunnel. Therefore, the appointed IP address (public network or private network address) can be distributed to the UE according to the AF requirement, and a third party is not required to construct a DHCP server.
