Inactive state UE context handling in service-based (r)adio access network

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least:
• send, to a radio access network data storage function via a service-based interface, at least one context information for at least one user equipment in a radio resource control inactive state;
• send, to the radio access network data storage function via the service-based interface, a first retrieve request to retrieve the at least one context information for the at least one user equipment in a radio resource control inactive state, wherein the first retrieve request comprises a context key, wherein the context key comprises,
• an inactive-radio network temporary identifier,
• a base station identifier, and
• a distributed unit identifier;
• and
• receive, via the service-based interface, the at least one context information from the radio access network data storage function.
