Method and system for managing utilization of slices in a virtual network function environment

A device, comprising:

• a processing system including a processor;
• and
• a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
• identifying a first group of virtual network functions of a first network slice instantiated within a software defined network and adapted to perform a first activity that facilitates delivery of a service to wireless equipment of a first user;
• facilitating, responsive to an occurrence of a network condition, access to a second group of virtual network functions, wherein the second group of virtual network functions when instantiated within a second network slice of the software defined network are configured to deliver the service to the wireless equipment of the first user, wherein the second network slice is further adapted to perform another activity that facilitates delivery of another service to the wireless equipment of the first user;
• and
• detecting the occurrence of the network condition, wherein the facilitating of the access to the second group of virtual network functions by the equipment of the first user further comprises identifying, responsive to the detecting of the occurrence of the network condition, a reserved network slice comprising the second group of virtual network functions, wherein access to the reserved network slice is not dedicated to equipment of any user.
