generating a slice profile for each pre-defined slice type by measuring performance of slices of each type in carrying data aggregated from a plurality of applications executing on a respective plurality of user equipment (UE);

receiving a request to access the 5G network from an application that is executing on the UE;

responsive to the access request, providing access to the application to a temporary slice of the 5G network;

a generating an application profile for the application by measuring performance of the temporary slice in carrying data from the application over the 5G network;

comparing the application profile to each of the slice typo profiles to identify a closest match; and

switching the application access to the 5G network from the temporary slice to a slice with a slice profile having the identified closest match to the application profile.

provide a monitoring functionality to each of a plurality of slices in a 5G (fifth generation) network, each slice being of a different pre-defined type, each monitoring functionality providing observations of behaviors of a respective slice in carrying data over the 5G network;

use the observed slice behaviors to generate a unique slice profile for each slice type respectively associated with the plurality of slices;

receive a request from an application executing on user equipment (UE) to access the 5G network, in which the request does not identify a slice type;

permit the application to access a temporary slice from the plurality of slices to carry data from the application over the 5G network in response to the request;

observe behavior of the application as the slice carries data from the application over the 5G network;

use the observed application behavior to generate an application profile; and

identify a slice profile of a slice type that most closely matches the application profile relative to slice profiles of other slice types.

10. The one or more hardware-based non-transitory computer-readable memory devices of claim 9 in which the computer-executable instructions, when executed, further cause the computing device to switch the application from the temporary slice to utilizing a slice of the type with the identified profile to carry application data over the 5G network.

11. The one or more hardware-based non-transitory computer-readable memory devices of claim 9 in which each slice type is associated with a pre-defined service provided on the 5G network.

12. The one or more hardware-based non-transitory computer-readable memory devices of claim 9 in which the request does not identify a slice type because the application is unaware of the slice type.

13. The one or more hardware-based non-transitory computer-readable memory devices of claim 9 in which the slice type profiles are defined by one or more of throughput, latency, or reliability over some predetermined time interval.

14. A computing device operable in a radio access network (RAN), comprising:

at least one processor; and

at least one hardware-based non-transitory computer-readable storage device having computer-executable instructions stored thereon which, when executed by the at least one processor, cause the computing device to:

observe one or more of throughput, latency, or reliability of data traffic on each of a plurality of slices in a 5G (fifth generation) network in which each slice has a different slice type;

generate a slice profile for each slice of the plurality of slices of the different slice types using the observations of data traffic on each slice of the plurality of slices;

observe one or more of throughput, latency, or reliability of data traffic from an application accessing a temporary slice among the plurality of slices in the 5G network;

a generate an application profile for the application using the observations of the data from the application carried on the selected temporary slice; and

switch application data traffic from the temporary slice to a slice having the slice profile that most closely matches the application profile relative to other slice profiles.

15. The computing device of claim 14 in which the computer-executable instructions, when executed by the least one processor, further cause the computing device to store the slice profiles in a data store.

18. The computing device of claim 14 in which the computer-executable instructions, when executed by the least one processor, further cause the computing device to determine data traffic demand by the application and in which the created application profile is based, at least in part, on the determined data traffic demand.
