         3 . An apparatus according to  claim 2 , wherein the time period increases after expiry of each time period. 
     
     
         4 . An apparatus according to  claim 1 , wherein the at least one memory and computer program code are configured to, with the at least one processor, cause the apparatus to, upon meeting the condition, provide a single notification for at least one occurrence of the at least one event or a combined notification for a plurality of occurrences of the at least one event. 
     
     
         5 . An apparatus according to  claim 1 , wherein the second network function is a network data analytics function or a consumer network function. 
     
     
         6 . An apparatus according to  claim 1 , wherein the first network function comprises a proxy function. 
     
     
         7 . An apparatus according to  claim 6 , wherein the at least one memory and computer program code are configured to, with the at least one processor, cause the apparatus to receive the request from the second network function at the proxy function via a third network function. 
     
     
         8 . An apparatus according to  claim 6 , wherein the at least one memory and computer program code are configured to, with the at least one processor, cause the apparatus to receive an indication of the at least one occurrence from at least one data source at the proxy function. 
     
     
         9 . An apparatus according to  claim 1 , wherein the first network function comprises at least one of an access and mobility management function, a session management function, a policy control function, unified data management, an application function or an operations, administration and management entity. 
     
     
         10 . An apparatus according to  claim 9 , wherein the at least one memory and computer program code are configured to, with the at least one processor, cause the apparatus to provide an indication from the first network function to a network resource function that the first network function supports conditional notification. 
     
     
         11 . An apparatus comprising: at least one processor and at least one memory including a computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus at least to:
 provide, to a first network function from a second network function, a request for notification of at least one event, wherein the request comprises at least one condition to trigger notification of the at least one event; and   receive a notification of the at least one event from the first network function at the second network function according to the at least one condition.   
     
     
         12 . An apparatus according to  claim 11 , wherein the at least one condition comprises one or more of a time window, a number of occurrences of the at least one event, an occurrence of an event other than the at least one event, a request from the second network function for notification of the at least one event or expiry of a time period. 
     
     
         13 . An apparatus according to  claim 12 , wherein the time period increases after expiry of each time period. 
     
     
         14 . An apparatus according to  claim 11 , wherein the second network function is a network data analytics function or a consumer network function. 
     
     
         15 . An apparatus according to  claim 11 , wherein the first network function comprises a proxy function. 
     
     
         16 . An apparatus according to  claim 15 , wherein the at least one memory and computer program code are configured to, with the at least one processor, cause the apparatus to provide the request from the second network function to the proxy function via a third network function. 
     
     
         17 . An apparatus according to  claim 11 , wherein the first network function comprises at least one of an access and mobility management function, a session management function, a policy control function, unified data management, an application function or an operations, administration and management entity. 
     
     
         18 . An apparatus according to  claim 17 , wherein the at least one memory and computer program code are configured to, with the at least one processor, cause the apparatus to receive an indication at the second network function from a network resource function that the first network function supports conditional notification. 
     
     
         19 . A method comprising:
 receiving, at a first network function from a second network function, a request for notification of at least one event, wherein the request comprises at least one condition to trigger notification of the at least one event; and   providing a notification of at least one occurrence of the at least one event to the second network function according to the at least one condition.
