Network entities for supporting analytics generation

A method for analytics generation, within a system for mobile operator network, the system comprising an Access Network (AN), a Core Network (CN), and a Data Network (DN), method carried out by a core network entity operating within a control plane of the CN of the mobile operator network, the method comprising:

• obtaining network slice association (NSA) information from one or more other network entities, the NSA information indicating a relation between an access network property and a mobile operator core network property;
• and
• providing analytics information, the analytics information being based on the obtained NSA information,
• wherein the NSA information comprises at least one information combination taken from the group consisting of:
• a first combination comprising a cell related to a tracking area (TA), an access type, and at least one of the group consisting of:
• one or more allowed single network slice selection assistance information (S-NSSAIs) or allowed network slice instances (NSIs),
• one or more restricted S-NSSAIs or restricted NSI(s), and
• one or more network functions (NFs), wherein for each NF, the NF is further related to at least one of the group consisting of:
• one or more allowed S-NSSAI(s) per public land mobile network (PLMN),
• one or more allowed NSI(s) per PLMN,
• one or more restricted S-NSSAI(s) per PLMN, and
• one or more restricted NSI(s) per PLMN;
• a second combination comprising a TA related to a list of cells, a supported access type, and at least one of the group consisting of:
• one or more allowed S-NSSAI(s),
• one or more allowed NSI(s), and
• one or more NFs, wherein for each NF, the NF is further related to at least one of the group consisting of:
• one or more allowed S-NSSAI(s) for each related NF, and
• one or more allowed NSI(s) for each related NF;
• a third combination comprising a TA related to a list of cells, a supported access type, and at least one of the group consisting of:
• one or more restricted S-NSSAI(s) or restricted NSI(s) per PLMN,
• one or more NFs, wherein for each NF, the NF is further related to at least one of the group consisting of:
• one or more restricted S-NSSAI(s) per PLMN, and
• one or more restricted NSI(s) per PLMN;
• a fourth combination comprising a NF related to a TA, wherein the TA is further related to:
• one or more cells,
• one or more access types, and
• one or more allowed S-NSSAI(s) per PLMN or allowed NSI(s) per PLMN;
• and
• a fifth combination comprising a NF related to a TA, wherein the TA is further related to:
• one or more cells,
• one or more access types, and
• one or more related restricted S-NSSAI(s) per PLMN or restricted NSI(s) per PLMN;
• wherein the obtaining NSA information comprises:
• sending a plurality of requests or subscribing to a plurality of NFs;
• and
• obtaining the NSA information from the plurality of NFs in response to the plurality of requests or subscribing to the plurality of NFs;
• wherein the method further comprises aggregating the NSA information obtained from the plurality of NFs;
• and
• wherein the providing analytics information comprises providing the analytics information based on the aggregated NSA information.
