Updating network functions in a telecommunications network utilizing atomic configuration snapshots

A method for managing network functions in a fifth-generation (5G) mobile packet core of a telecommunications network, the method comprising:

• receiving, across multiple requests, multiple network function changes to modify the network functions of the telecommunications network;
• adding the multiple network function changes incrementally to a pending changes set without applying the multiple network function changes to the telecommunications network;
• generating a configuration snapshot that includes the multiple network function changes in the pending changes set, wherein generating the configuration snapshot includes, prior to implementing the multiple network function changes represented within the configuration snapshot, cross-validating the multiple network function changes against each other in the pending changes set;
• and
• activating the configuration snapshot across the telecommunications network in a single operation, such that the multiple network functions transition as a batch of network functions from a current state of a plurality of network functions to the desired state across all network functions of the plurality of network functions by implementing the multiple network function changes in the pending changes set atomically to ensure all of the multiple network function changes successfully implement.
