[0080] In the embodiments of the present application, the term "and / or" describes a relationship between related objects and indicates that there are three possible relationships. For example, A and / or B may indicate three cases: only A is present, both A and B are present, and only B is present. The symbol " / " generally indicates an "or" relationship between the related objects before and after it.

[0081] In the present application, the term "plurality" means two or more, and similarly for other quantifiers.

[0082] Hereinafter, the technical aspects of the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, but it is obvious that the described embodiments are only some of the embodiments of the present application, and are not all of the embodiments. Based on the embodiments of the present application, other embodiments obtained by those skilled in the art without paying creative labor shall all be within the scope of protection of the present application.

[0083] Referring to Fig. 1, Fig. 1 is a flow chart of an information processing method according to an embodiment of the present application, which is applied to a first network function, where the first network function includes at least one of a NEF, an SMF, a UPF, a PCF, and a network address translation function, where the network address translation function may be a newly added network address translation function. As shown in Fig. 1, the method includes the following steps 101-102.

[0084] Step 101 is to obtain network address translation information from a first device or function.

[0085] Among them, the first device or function is: The network address translation function includes one or more of a network address translation device, a network address translation network element, an external function, a device or function or network element having network address translation information, and a device or function or network element having a network address translation function.

[0086] For example, in practical applications, the first device or function may be a NAT, and the NAT may be designed as a network function (Network Function, NF), i.e., NATF (NAT (Network Address Translation) NF).

[0087] The network address translation information includes: The information includes one or more of a correspondence relationship between a public network address and a private network address, a public network address, a private network address, a port number of the public network address, and a port number of the private network address.

[0088] In an embodiment of the present application, for example, the external address (outside the 5GC) of the NAT is a public network address, and inside the 5GC, a private network address is used.

[0089] In the embodiments of the present application, the network address translation information can be obtained in various ways.

[0090] For example, the first network function may determine 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 may store it for subsequent use. In this case, the first network function may be a NEF, etc.

[0091] Further, for example, the first network function can obtain a first request of an application function (AF), the first request including a public network address, and determine a target first device or function according to the first request. Then, the first network function obtains the correspondence between the public network address and a private network address, or a private network address corresponding to the target public network address, from the target first device or function. That is, in this case, network address translation information is obtained according to the first request of AF. In this case, when the correspondence between the public network address and the private network address is obtained from the target first device or function, the first network function can also determine a private network address corresponding to the public network address in a subsequent step according to the public network address and the correspondence between the public network address and the private network address. Among them, the first request can be, for example, a User Equipment (UE) Identifier Query Request or a Session Binding Request, etc. In this case, the first network function can be a NEF, etc.

[0092] Further, for example, the first network function may obtain a second request from the AF, which is a second request for requesting a mapping relationship between a public network address and a private network address. Then, the first network function may determine a target first device or function according to the second request, and obtain the mapping relationship between the public network address and the private network address from the target first device or function. That is, in this case, network address translation information is obtained according to the first request from the AF. At this time, the first network function may be an SMF, a UPF, a PCF, etc. The second request may be sent, for example, when the AF needs to request capability disclosure information.

[0093] According to the above several methods, the acquisition of network address translation information can be flexibly realized to adapt to the needs of various scenarios.

[0094] In practical application, a first device or function can be registered with the NRF, and other devices or functions can search for a target first device or function through the NRF and obtain network address translation information from the target first device or function, where the target first device or function is a first device or function that can be discovered by the NRF. After obtaining the network address translation information from the target first device or function, the other devices or functions can obtain it by invoking the service of the target first device or function.

[0095] Specifically, in some of the above cases, the first network function can determine the target first device or function via the NRF.

[0127] Referring to FIG. 5, FIG. 5 is a flow chart of an information processing method according to an embodiment of the present application. Wherein, a first network function (NEF) obtains address mapping information of a first device or function (NATF). The NEF invokes a service of the NATF to obtain network address translation information. The NEF and the NATF may interact through a service-based interface, and the NATF may register its information in the NRF to facilitate the NEF to find the corresponding NATF through a service discovery function.

[0136] Step 506 is for the NEF to obtain a private network address for the UE of the session according to the public network address information provided by the AF and the network address translation information provided by the NATF.
