[0290] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0291] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0292] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0293] See Figure 1 , Figure 1 This is a flowchart of an information processing method provided in an embodiment of this application, applied to a first network function. The first network function includes at least one of the following: NEF; SMF; UPF; PCF; and network address translation (NAT). The NAT function may be a newly added NAT function. Figure 1 As shown, the method includes the following steps:

[0294] Step 101: Obtain network address translation information from the first device or function.

[0295] The first device or function includes one or more of the following:

[0296] Network address translation function; network address translation device; network address translation network element; external function; device or function or network element with network address translation information; device or function or network element with network address translation function.

[0297] For example, in practical applications, the first device or function may be NAT, where NAT can be designed as an NF (Network Function), namely NATF (Network Address Translation NF).

[0298] The network address translation information includes one or more of the following:

[0299] The mapping between public and private network addresses; public network address; private network address; port number of public network address; port number of private network address.

[0300] In this embodiment of the application, for example, the external address of NAT (outside of 5GC) is a public network address, while the internal address of 5GC is a private network address.

[0301] In the embodiments of this application, network address translation information can be obtained through various methods.

[0302] For example, a first network function can identify a target first device or function and obtain the network address translation information from the target first device or function. After obtaining the network address translation information, the first network function can store it for later use. In this case, the first network function can be NEF, etc.

[0303] For example, a first network function may obtain a first request from application function AF, the first request including a public network address, and determine a target first device or function based on the first request. Then, the first network function obtains the mapping relationship between the public network address and the private network address, or the private network address corresponding to the target public network address, from the target first device or function. That is, this situation involves obtaining network address translation information in response to the first request from AF. In this case, when obtaining the mapping relationship between the public network address and the private network address from the target first device or function, the first network function can further determine the private network address corresponding to the public network address in subsequent steps based on the public network address and the mapping relationship between the public network address and the private network address. The first request may be, for example, a UE (User Equipment) identifier query request or a session binding request. In this case, the first network function may be NEF, etc.

[0304] For example, the first network function can also receive a second request from the AF, which requests the mapping relationship between public and private network addresses. Then, based on the second request, the first network function can determine a target first device or function and obtain the mapping relationship between the public and private network addresses from the target first device or function. That is, this situation involves obtaining network address translation information in response to a first request from the AF. In this case, the first network function can be an SMF, UPF, PCF, etc. The second request can be, for example, sent by the AF when it needs to request capability openness information.

[0305] The above methods can be used to flexibly obtain network address translation information to meet the needs of different scenarios.

[0306] In practical applications, a first device or function can be registered with the NRF. Other devices or functions can then locate the target first device or function through the NRF and obtain network address translation information from it. The target first device or function refers to any device or function that can be discovered by the NRF. When obtaining network address translation information from the target first device or function, other devices or functions can obtain it by calling the services of the target first device or function.

[0307] Specifically, in the above scenarios, the first network function can determine the target first device or function through the NRF. Specifically, the first network function can send a third request to the NRF and receive information about the target first device or function sent by the NRF based on the third request. The third request includes information about a private network address and / or a public network address; the private network address information includes one or more of the following: an IPv4 address, an IPv6 prefix, and an IP domain; the public network address information includes one or more of the following: an IPv4 address and an IPv6 prefix. The information about the target first device or function may, for example, be the name of the first network or function, an instance ID, etc.

[0308] In the above scenarios, when it is necessary to obtain the mapping relationship between the public network address and the private network address from the target first device or function, the first network function can invoke the service of the target first device or function to obtain the mapping relationship between the public network address and the private network address from the target first device or function. Specifically, the first network function sends a fourth request to the target first device or function and receives the mapping relationship between the public network address and the private network address sent by the target first device or function according to the fourth request. The fourth request includes the ID and / or type of the first network function.

[0309] In the above scenarios, the first network function can invoke the service of the first device or function to obtain the private network address corresponding to the public network address from the target first device or function. Specifically, the first network function sends a fifth request to the target first device or function and receives the private network address corresponding to the public network address sent by the target first device or function according to the fifth request. The fifth request includes the ID and / or type of the first network function and the private network address.

[0310] Step 102: Process the network address translation information.

[0311] In this step, the first network function mainly performs one or more of the following: mapping a public network address to a private network address according to the request of the AF; and mapping a private network address to a public network address according to the request of the second device or function. The second device or function can be any device or function in the network that needs to map a private network address to a public network address.

[0312] In this embodiment, the first network function can obtain network address translation information from the first device or function, and process the information accordingly. Using the solution of this embodiment, since the first network function can obtain network address translation information, it can implement the corresponding network address translation function, thereby enabling end-to-end control.

[0313] See Figure 2 , Figure 2 This is a flowchart of an information processing method provided in an embodiment of this application, applied to a first device or function. The first device or function includes one or more of the following: a network address translation (NAT) function; a network address translation (NAT) device; a network address translation (NAT) element; an external function; a device, function, or network element having network address translation information; or a device, function, or network element having a network address translation function. For example, in practical applications, the first device or function may be NATF. Figure 2 As shown, the method includes the following steps:

[0314] Step 201: Send network address translation information to the first network function, wherein the network address translation information includes one or more of the following:

[0315] The mapping between public and private network addresses; public network address; private network address; port number of public network address; port number of private network address.

[0316] In this step, the first device or function may receive a request from the first network function, including the ID and / or type of the network device of the first network function, and send the network address translation information to the first network function according to the request.

[0317] The meaning of the first network function can be referred to the description in the foregoing embodiments. The request may also include one or more of the following: information on candidate public network addresses and information on candidate private network addresses. The information on candidate public network addresses or candidate private network addresses can be understood, for example, as the public network address or private network address that the first network function expects to obtain.

[0318] In addition, the first function or device may also send a sixth request to the NRF, the sixth request being used to register with the NRF, wherein the sixth request includes: information of a private network address and / or information of a public network address; wherein the information of the private network address includes one or more of the following: IPv4 address range, IPv46 prefix range, IP domain information, and port number; the information of the public network address includes one or more of the following: IPv4 address range, IPv46 prefix range, and port number.

[0319] In this embodiment of the application, taking NATF as an example, one or more NATF services can be defined. The information of these services is as follows:

[0320] Service 1: Nnatf_event exposure service

[0321] Service Name: This service allows for service call operations such as subscribe / notify and request / response.

[0322] Service Description: Allows other NFs to make service calls to NATF and obtain the mapping relationship between private network addresses and public network addresses; or, based on the provided private network address / public network address, maps it to the corresponding public network address / private network address; or, provides the port number of the public network address; or, provides the port number of the private network address, etc.

[0323] Input parameters: NF ID (NF identifier) ​​or NF type to access, optional private network address / public network address.

[0324] Output parameters: optional public IP address / private IP address, mapping relationship between private IP address and public IP address; port number of public IP address; port number of private IP address.

[0325] Table 1 shows the network information stored by NATF, which can also be information sent by NATF to NEF.

[0326] Table 1

[0327]

[0328] NATF can register by calling NRF's services. Specifically, NATF calls NRF's Nnrf_NFManagement_NFRegister service to register its NF profile (NF attributes) with NRF. The NF profile includes, but is not limited to: NF type, NF instance ID, NF FQDN (Fully Qualified Domain Name) or IP address, NF service name, network slice information, DNN (Data Network Name) information, private network address information, and public network address information. The private network address information includes: IPv4 address range, IPv6 prefix range, IP domain information (IP domain list), and port number; the public network address information includes the IPv4 address range, IPv6 prefix range, and port number.

[0329] Other network elements (NFs), such as NEFs, can call the NRF's Nnrf_NFDiscovery_Request service to discover target NATFs. The input parameters for Nnrf_NFDiscovery_Request include, but are not limited to: one or more target NF service name(s), the NF type of the target NF, the NF type of the NF service consumer, network slice information, DNN information, public IP address information, and private IP address information. Public IP address information includes IPv4 address or IPv6 prefix, and private IP address information includes IPv4 address, IPv6 prefix, and IP domain. The NRF output query result is the NATF instance ID, etc.

[0330] In addition, the first function or device may also send a seventh request to the NRF for deregistration with the NRF; and / or send an eighth request to the NRF for registration update with the NRF.

[0331] For example, NATF can call NRF's Nnrf_NFManagement_NFderegister to deregister, or it can call NRF's Nnrf_NFManagement_NFUpdate to register and update.

[0332] In this embodiment, the first network function can obtain network address translation information from the first device or function, and process the information accordingly. Using the solution of this embodiment, since the first network function can obtain network address translation information, it can implement the corresponding network address translation function, thereby enabling end-to-end control.

[0333] See Figure 3 , Figure 3 This is a flowchart of an information processing method provided in an embodiment of this application, applied to NRF. For example... Figure 3 As shown, the method may include:

[0334] Step 301: Obtain the request for the first network function.

[0335] Step 302: According to the request, send information about a first device or function to the first network function, wherein the first device or function is used to provide network address translation information or perform network address translation based on the network address translation information.

[0336] The network address translation information includes one or more of the following:

[0337] The mapping between public and private network addresses;

[0338] Public IP address;

[0339] Private network address;

[0340] The port number of the public IP address;

[0341] The port number of the private network address.

[0342] The information of the first function or device may be, for example, the name of the first function or device, instance ID, etc.

[0343] In addition, the NRF can also receive a sixth request from the first device or function, and register the first device or function according to the sixth request; wherein the sixth request includes: information of a private network address and / or information of a public network address; the information of the private network address includes one or more of the following: IPv4 address range, IPv46 prefix range, IP domain information, and port number; the information of the public network address includes one or more of the following: IPv4 address range, IPv46 prefix range, and port number.

[0344] In addition, NRF can perform one or more of the following:

[0345] Receive a seventh request from the first device or function, and register the first device or function according to the seventh request;

[0346] Receive the eighth request from the first device or function, and update the registration of the first device or function according to the eighth request.

[0347] In this embodiment, the first network function can obtain network address translation information from the first device or function, and process the information accordingly. Using the solution of this embodiment, since the first network function can obtain network address translation information, it can implement the corresponding network address translation function, thereby enabling end-to-end control.

[0348] See Figure 4 , Figure 4 This is a flowchart of an information processing method provided in an embodiment of this application, applied to a first network function. For example... Figure 4 As shown, the method may include:

[0349] Step 401: Discover a first device or function through NRF, wherein the first device or function is used to provide network address translation information or perform network address translation based on network address translation information;

[0350] The network address translation information includes one or more of the following:

[0351] The mapping between public and private network addresses;

[0352] Public IP address;

[0353] Private network address;

[0354] The port number of the public IP address;

[0355] The port number of the private network address.

[0356] Specifically, in this step, the first network function sends a request to the NRF and receives information about the first device or function sent by the NRF according to the request. The request includes information about a private network address and / or a public network address; the private network address information includes one or more of the following: an IPv4 address, an IPv6 prefix, and an IP domain; the public network address information includes one or more of the following: an IPv4 address and an IPv6 prefix.

[0357] In this embodiment, the first network function can obtain network address translation information from the first device or function, and process the information accordingly. Using the solution of this embodiment, since the first network function can obtain network address translation information, it can implement the corresponding network address translation function, thereby enabling end-to-end control.

[0358] In the above embodiments, the specific implementation method of various requests is not limited, as long as it can be implemented using the communication mechanism between the two parties.

[0359] See Figure 5 , Figure 5 This is a flowchart of an information processing method according to an embodiment of this application. In this method, a first network function (NEF) obtains address mapping information from a first device or function (NATF). The NEF calls the NATF's service to obtain network address translation information. The NEF and NATF can interact through a service-based interface; the NATF can register its own information with the NRF, facilitating the NEF to find the corresponding NATF through service discovery. The process of this embodiment can be applied to processes such as the AF performing session binding information querying and the AF requesting UE identifiers. Figure 5 As shown, the process may include:

[0360] Step 500: NATF registers with NRF.

[0361] The registration process can be referred to the relevant content described in the above embodiments.

[0362] Step 501: Before any session establishment or specific AF request, the NEF calls the NRF service to find the target NATF. When calling the NRF service, the NEF can input parameters including network slice information, DNN information, and location information (UE location or NEF location).

[0363] Step 502: NEF calls the target NATF's service to obtain network address translation information and stores it in NEF to prepare for subsequent AF requests.

[0364] Steps 502 and 503 can be performed as separate processes.

[0365] Step 503: AF requests NEF to perform session binding or UE identifier query.

[0366] Step 504: NEF calls NRF's service to find the target NATF.

[0367] Step 505: NEF calls the target NATF's service to obtain network address translation information.

[0368] In this embodiment of the application, the network address translation information may include the correspondence between public network addresses and private network addresses, public network address, private network address, port number of public network address, and port number of private network address.

[0369] The NEF provides the target NATF with the UE IP address (i.e., the UE's public IP address corresponding to the session) and obtains the NATF's network address translation information (including the private IP address of the session).

[0370] Step 506: The NEF obtains the private network address of the UE for this session based on the public network address information provided by the AF and the network address translation information provided by the NATF.

[0371] Step 507: NEF uses the aforementioned private network address to initiate a session binding process or a UE identifier query process.

[0372] Following step 503, if the NEF itself stores network address translation information, the NEF can obtain the private network address of the UE for this session based on the public network address information provided by the AF and the network address translation information. Then, step 507 is executed. That is, steps 504-506 can be omitted at this point.

[0373] In step 505 above, NEF can also directly obtain the UE private address corresponding to the session from NATF, in which case step 506 can be omitted.

[0374] Through the above process, network address translation and session binding can be implemented in 5GC.

[0375] See Figure 6 , Figure 6 This is a flowchart of an information processing method according to an embodiment of this application. It is a schematic diagram illustrating the process by which a first network function (SMF / UPF / PCF) obtains network address translation information from a first device or function (NATF) according to an embodiment of this application. Figure 6 As shown, the process may include:

[0376] Step 600: NATF registers with NRF.

[0377] The registration process can be referred to the relevant content described in the above embodiments.

[0378] Step 601: The AF requests information from the NEF regarding capability access, including requesting network address translation (NAT) information. Here, the NAT information may include, for example, the mapping between public and private network addresses.

[0379] Step 602: NEF finds the corresponding SMF / UPF through PCF, etc., and makes an open request for the relevant information.

[0380] Step 603: SMF / UPF finds the corresponding target NATF by calling NRF services.

[0381] Step 604: SMF / UPF requests network address translation information from the target NATF by calling the target NATF's service.

[0382] Step 605: The target NATF sends network address translation information back to the SMF / UPF.

[0383] Step 606: SMF / UPF feeds back network address translation information to NEF.

[0384] Step 607: NEF sends network address translation information back to AF.

[0385] Through the above process, network address translation can be implemented in 5GC, and capability opening can also be achieved.
