Section: 4.26.3 NF/NF Service Context Transfer Pull procedure
Content: Figure 4.26.3-1: NF/NF Service Context Pull procedure 1. When triggered, the Target NF/NF Service as an NF Service Consumer requests a Context (e.g. UE context or SM context) from the Source NF as a NF Service Producer. This may trigger several other procedures that ensure all necessary NF/NF services are being updated and set up with necessary information about the new context location. NOTE 1: Which procedures need to be executed and what information needs to be updated is part of the specific context transfer procedures as specified in clause 4.26.5. 2. The NF Service Consumer receives the Context and the operation was successful. When all procedures have been executed successfully the Target NF/NF Service can continue to serve the original NF Service Consumers of the Source NF/NF Service, which e.g. can be shut down gracefully. NOTE 2: After resumption of a new service transaction, it may be necessary to contact the UE using existing procedures.
