[0050] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0051] The service providing method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the SEPP network element 102 communicates with the NRF (Network Repository Function) network element 104 through the network. The data storage system can store data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. By receiving the initial service request carrying the target FQDN sent by the service demander, the address of the target FQDN is reversed to obtain the service network address; and the service network address is used to replace the target FQDN in the initial service request to obtain the target service request; then, the target service request is sent to the service producer, so that the service producer provides services to the service demander according to the functional network element corresponding to the service network address.

[0052] In one embodiment, Figure 2 As shown, a service providing method is provided, which is applied to Figure 1 The SEPP network element in the example is used to illustrate, including the following steps:

[0053] S201, receiving an initial service request sent by a service demander.

[0054] The initial service request carries a target fully qualified domain name FQDN; the target FQDN is generated by the SEPP network element according to the service network address carried in the service discovery response after receiving the service discovery response sent by the network repository function NRF network element to the service demander;

[0055] In one embodiment of the present application, the service demander sends an initial service request to the Serving SEPP network element of the Serving PLMN (Serving Public Land Mobile Network); the Serving SEPP network element forwards the initial service request to the Home SEPP network element of the Home PLMN (Home Public Land Mobile Network), which is the executor of the service provision method, thereby implementing the operation of receiving the initial service request sent by the service demander.

[0056] The service discovery response is a response sent by the NRF network element to the SEPP network element after receiving the service discovery request sent by the service demander.

[0057] S202, performing an inverse address transformation on the target FQDN to obtain a service network address.

[0058] It should be noted that since the target FQDN is generated by the SEPP network element after receiving the service discovery response sent by the network repository function NRF network element to the service demander, based on the service network address carried in the service discovery response, the service network address can be obtained by performing an inverse transformation on the target FQDN.

[0059] In one embodiment of the present application, if the target FQDN is a service network address obtained through encryption, when the service network address needs to be obtained, the target FQDN can be decrypted to obtain the service network address.

[0060] In another embodiment of the present application, when it is necessary to perform an address inverse transformation on the target FQDN, a mapping relationship between the target FQDN and the service network address can be obtained in advance, wherein the mapping relationship records at least one candidate FQDN and different candidate network addresses corresponding to each candidate FQDN; then, based on the mapping relationship, the target FQDN is subjected to an address inverse transformation to obtain the service network address.

[0061] Specifically, after determining the target FQDN, the target FQDN is compared with at least one candidate FQDN recorded in the mapping relationship for similarity, and the candidate FQDN among the candidate FQDNs that is the same as the target FQDN is used as the reference FQDN; further, the candidate network address corresponding to the reference FQDN in the mapping relationship is used as the service network address.

[0062] S203, replacing the target FQDN in the initial service request with the service network address to obtain a target service request.

[0063] In one embodiment of the present application, the data location of the target FQDN in the initial service request is determined, and then, after the service network address is determined, the service network address is replaced with the target FQDN at the data location to obtain the target service request.

[0064] S204: Send the target service request to the service producer, so that the service producer provides services to the service demander according to the functional network element corresponding to the service network address.

[0065] The above-mentioned service provision method receives the initial service request sent by the service demander and carries the target FQDN, so as to perform an address inverse transformation on the target FQDN and obtain the service network address; and replaces the target FQDN in the initial service request with the service network address to obtain the target service request; and then sends the target service request to the service producer, so that the service producer provides services to the service demander according to the functional network element corresponding to the service network address. According to the above content, the present application receives the initial service request sent by the service demander to replace the service network address for the target FQDN in the initial service request, and realizes that the service network address can be sent when the address of the target FQDN is only reversely transformed by the SEPP network element to obtain the service network address, without the need for functional adjustment of other network elements, so that the communication organization does not need to build a DNS or database, which reduces the management and maintenance cost of maintaining the mapping relationship between the entire network FQDN and the service network address in the domain, and also reduces the risk of interruption of business transmission, and eliminates the potential hidden danger of service interruption caused by untimely update of the mapping relationship data between FQDN and service network address.

[0066] In one embodiment, if Figure 3 As shown, when it is necessary to generate a target FQDN based on the service network address carried in the service discovery response, the following contents may be included:

[0067] S301, extracting the service network address of the service producer carried in the service discovery response.

[0068] Specifically, the network address of the service discovery response is identified to locate the data location corresponding to the service network address in the service discovery response, and then, based on the data location corresponding to the service network address, the service network address of the service producer carried in the service discovery response is extracted.

[0069] The service discovery response is a response sent by the NRF network element to the SEPP network element after receiving the service discovery request sent by the service demander.

[0070] In one embodiment of the present application, after the Serving SEPP network element forwards the initial service request to the Home SEPP network element of the Home PLMN, the execution subject of the service provision method, the Home SEPP network element forwards the initial service request to the Home NRF network element, and the Home NRF network element forwards the initial service request to the Home PLMN.

[0071] S302, encrypt the service network address to determine the target FQDN.

[0072] It should be noted that when it is necessary to encrypt the service network address, the following contents may be included: encrypting the service network address to obtain an encrypted string; adding the communication organization domain name information to the suffix of the encrypted string, and using the encrypted string with the communication organization domain name information added to the suffix as the target FQDN.

[0073] As an example, if the service network address is 10.1.1.1, the local algorithm is used to encrypt and generate an encrypted string djg640jfdsk; the communication agency domain name information 5gc.mnc012.mcc345.3gppnetwork.org is added to the suffix of the encrypted string, and the target FQDN is: djg640jfdsk.5gc.mnc012.mcc345.3gppnetwork.org.

[0074] To further explain, since the target FQDN is an encrypted string with the communication organization domain name information added to the suffix, when performing address inverse transformation on the target FQDN to obtain the service network address, the following method can be used: decrypt the target FQDN to obtain the service network address.

[0075] Specifically, since the target FQDN contains not only the encrypted string but also the domain name information of the communication organization, only the encrypted string contained in the target FQDN is decrypted to obtain the service network address.

[0076] As an example, if the target FQDN information is djg640jfdsk.5gc.mnc012.mcc345.3gppnetwork.org, the SEPP network element decrypts the encrypted string contained in the target FQDN to obtain the service network address 10.1.1.1. The SEPP network element then uses the service network address to replace the target FQDN in the initial service request to obtain the target service request.

[0077] The above-mentioned service providing method encrypts the service network address to add the communication organization domain name information to the suffix of the encrypted string to obtain the target FQDN, thereby achieving the purpose of obtaining the service network address by decrypting the encrypted string contained in the target FQDN, and achieving the sending of the service network address when the target FQDN is only reversely transformed by the SEPP network element to obtain the service network address, without the need for functional adjustment of other network elements, so that the communication organization does not need to build a DNS or database, thereby reducing the management and maintenance costs of maintaining the mapping relationship between the entire network FQDN and the service network address in the domain, and also reducing the risk of service transmission interruption.

[0078] In one embodiment, if Figure 4 As shown, when the target service request needs to be sent to the service producer, the following contents may be included:

[0079] S401: receiving an initial service request sent by a service demander.

[0080] S402, decrypt the encrypted string contained in the target FQDN to obtain a service network address.

[0081] S403, replacing the target FQDN in the initial service request with the service network address to obtain a target service request.

[0082] S404: Send the target service request to the service producer, so that the service producer provides services to the service demander according to the functional network element corresponding to the service network address.

[0083] In one embodiment of the present application, the process of the SEPP network element generating the target FQDN is as follows: Figure 5As shown, the service demander sends a service discovery request to the Serving NRF network element of the Serving PLMN (Serving Public Land Mobile Network); the Serving NRF network element forwards the service discovery request to the Serving SEPP network element; the Serving SEPP network element forwards the service discovery request to the Home SEPP network element of the Home PLMN (Home Public Land Mobile Network), which is the executor of the service provision method, and the Home SEPP network element forwards the service discovery request to the Home NRF network element; after the Home NRF network element generates a service discovery response for the service discovery request, it sends the service discovery response to the Home SEPP network element; after receiving the service discovery response sent by the Home NRF network element to the service demander, the Home SEPP network element generates a target FQDN according to the service network address carried in the service discovery response, and sends the service discovery response carrying the target FQDN to the Serving SEPP network element; the Serving SEPP network element sends the service discovery response to the Serving NRF network element; the Serving NRF network element sends the service discovery response to the service demander.

[0084] Furthermore, the service discovery request may include, but is not limited to: a service discovery request and a network element status subscription request, etc., and the request type of the service discovery request is not limited herein.

[0085] In one embodiment of the present application, the process of sending the target service request to the service producer is as follows: Figure 6 As shown, the service demander sends the initial service request to the Serving SEPP network element; the Serving SEPP network element sends the initial service request to the Home SEPP network element, the Home SEPP network element performs an address inverse transformation on the target FQDN, obtains the service network address, and sends the target service request to the service producer.

[0086] The above-mentioned service providing method receives an initial service request carrying a target FQDN sent by a service demander to perform an address inverse transformation on the target FQDN to obtain a service network address; and uses the service network address to replace the target FQDN in the initial service request to obtain a target service request; and then, sends the target service request to a service producer so that the service producer provides services to the service demander according to the functional network element corresponding to the service network address.

[0087] According to the above content, the present application receives the initial service request sent by the service demander to realize the replacement of the service network address for the target FQDN in the initial service request, and realizes the sending of the service network address when the service network address is obtained by performing an address inverse transformation on the target FQDN only through the SEPP network element, without the need for functional adjustment of other network elements, so that the communication organization does not need to build a DNS or database, thereby reducing the management and maintenance cost of maintaining the mapping relationship between the FQDN and the service network address of the entire network in the domain, and also reducing the risk of interruption in business transmission, eliminating the potential hidden dangers of service interruption caused by untimely update of the mapping relationship data between the FQDN and the service network address.
