Abstract

The present application discloses a network function registration method and discovery method, an apparatus, a device and a medium belonging to the mobile communication field. The method introduces S-NSSAI, a DNN and a data processing method in the network function registration and discovery processes, so that the S-NSSAI, DNN and data processing method can be directly provided to a consumer network function in a network function discovery process for use.

What is claimed is: 
     
         1 . A network function registration method comprising:
 sending, by a first network function, a registration request to a second network function, wherein single-network slice selection assistance information (S-NSSAI) and a data network name (DNN) are carried in the registration request.   
     
     
         2 . The method according to  claim 1 , wherein a data processing method is also carried in the registration request. 
     
     
         3 . The method according to  claim 2 , wherein the data processing method comprises at least one of data anonymization, data aggregation and data normalization. 
     
     
         4 . The method according to  claim 1 , wherein at least one of a network function identity, an application identity, an event identity and a terminal identity of the first network function is also carried in the registration request. 
     
     
         5 . The method according to  claim 1 , wherein the second network function is a network function repository function (NRF). 
     
     
         6 . A network function discovery method comprising:
 sending, by a third network function, a discovery request to a second network function, the discovery request being used for requesting to discover a target network function (NF); and   receiving, by the third network function, a discovery response sent by the second network function, wherein an identity of the target NF and at least one of single-network slice selection assistance information (S-NSSAI) and a data network name (DNN) of the target NF are carried in the discovery response.   
     
     
         7 . The method according to  claim 6 , wherein a data processing method is also carried in the discovery response. 
     
     
         8 . The method according to  claim 7 , wherein the data processing method comprises at least one of data anonymization, data aggregation and data normalization. 
     
     
         9 . The method according to  claim 6 , wherein information carried in the discovery request also includes at least one of:
 an application identity;   an event identity;   a terminal identity; and   a requested data processing method.   
     
     
         10 . The method according to  claim 6 , further comprising:
 determining, by the third network function, a first Internet Protocol (IP) address of a terminal according to information carried in the discovery response; and   sending, by the third network function, the first IP address of the terminal to the target NF.   
     
     
         11 . A network function registration apparatus comprising:
 a transmitter configured to send a registration request to a second network function, wherein single-network slice selection assistance information (S-NSSAI) and a data network name (DNN) are carried in the registration request.   
     
     
         12 . The apparatus according to  claim 11 , wherein a data processing method is also carried in the registration request. 
     
     
         13 . The apparatus according to  claim 12 , wherein the data processing method comprises at least one of data anonymization, data aggregation and data normalization. 
     
     
         14 . The apparatus according to  claim 11 , wherein at least one of a network function identity, an application identity, an event identity and a terminal identity of the first network function is also carried in the registration request. 
     
     
         15 . The apparatus according to  claim 11 , wherein the second network function is a network function repository function (NRF). 
     
     
         16 . A network function discovery apparatus comprising:
 a transmitter configured to send a discovery request to a second network function, the discovery request being used for requesting to discover a target network function (NF); and   a receiver configured to receive a discovery response sent by the second network function, wherein an identity of the target NF and at least one of single-network slice selection assistance information (S-NSSAI) and a data network name (DNN) of the target NF are carried in the discovery response.   
     
     
         17 . The apparatus according to  claim 16 , wherein a data processing method is also carried in the discovery response. 
     
     
         18 . The apparatus according to  claim 17 , wherein the data processing method comprises at least one of data anonymization, data aggregation and data normalization. 
     
     
         19 . The apparatus according to  claim 16 , wherein information carried in the discovery request also includes at least one of:
 an application identity;   an event identity;   a user equipment (UE) identity; and   a requested data processing apparatus.   
     
     
         20 . The apparatus according to  claim 16 , further comprising:
 a processor configured to determine a first Internet Protocol (IP) address of a terminal according to information carried in the discovery response;   wherein the transmitter is further configured to send the first IP address of the terminal to the target NF.
