NETWORK SLICE SELECTION

Abstract:

Selecting a network slice (202a-n) to which a User Equipment, UE, (204a-b) can connect in the telecommunications network. A CIR (216) stores, based on content data received from a plurality of Cache NFs (210), cache associations indicating content cached at each of the Cache NFs and the network slice in which each Cache NF is located. An NSSF (218) transmits to the CIR a request for cache data indicating a particular content cached in one or more network slices. The CIR determines the requested cache data based on the stored cache associations and transmits the requested cache data to the NSSF. The cache data comprises at least one of: one or more Cache NFs and one or more network slices caching the particular content. The NSSF selects a network slice to which the UE can connect, based at least in part on the received cache data identifying the one or more network slices.
