Mechanism for accessing subscription data

An apparatus, comprising:

• at least one processor, and
• at least one memory for storing instructions which, when executed by the at least one processor, cause the apparatus at least to:
• receive, with a request for data, query information as part of a data retrieving process to read subscription data from the apparatus, the query information being set for filtering sub-resources of subscription information within the subscription data and for requesting a return of the data according to the request in a single response,
• wherein the request for the data is obtained by a communication via an application programming interface to the apparatus,
• wherein the request for the data comprises a get message, the get message including:
• an indication that the subscription data are requested,
• an identification of a communication element or a communication function,
• an indication that context data are concerned,
• an indication regarding event exposure subscriptions, and
• the query information comprising:
• an indication of at least one of a specific communication network element type or a specific communication network function type, and
• an identification of at least one of a designated communication network element or a designated communication network function;
• and
• provide the single response including the data to a management network element or a management network function.

A method comprising:

• providing, with a request for data, query information as a part of a data retrieving process to read subscription data from a data repository element or a data repository function, the query information being set for filtering sub-resources of subscription information within the subscription data and for requesting a return of the data according to the request in a single response;
• conducting the data retrieving process by using a communication via an application programming interface to the data repository element or the data repository function;
• providing the request for the data by using a get message, the get message including:
• an indication that the subscription data are requested,
• an identification of a communication element or a communication function,
• an indication that context data are concerned,
• an indication regarding event exposure subscriptions, and
• the query information comprising at least one of:
• an indication of at least one of a specific communication network element type or a specific communication network function type, or
• an identification of at least one of a designated communication network element or a designated communication network function;
• and
• receiving the single response including the data.
