6 Consolidated requirements p. 19

6.1 Groups of interconnected SNPNs p. 19

The potential requirements for enabling groups of interconnected SNPNs correspond to the use cases in clauses 5.2 to 5.5 and are listed in Table 6.1-1.

A group of interconnected SNPNs consists of one or more pairs of interconnected SNPNs. The determination of whether a given SNPN can or should be able to participate within a given group of interconnected SNPNs is based on prior arrangement and out of band configuration. How these arrangements and configuration are made is outside the scope of 3GPP and the 5G network.

CPR #	Consolidated Potential Requirement	Original PR #
CPR 6.1-1	Based on SNPN configuration and subject to SNPN operator's policy, the 5G network shall be able to support mechanisms to enable interconnect between two or more SNPNs NOTE: The interconnect can be established on temporary basis forming a group of interconnected SNPNs with variable topologies.

CPR 6.1-2	Based on SNPN configuration and subject to SNPN operator's policy, the 5G network shall be able to support prioritization of resources for a service offered by a SNPN that is consumed by users attached to other interconnected SNPNs	[PR 5.5.6-001]
CPR 6.1-3	Based on SNPN configuration and subject to SNPN operator's policy, the 5G network shall be able to support service continuity for UEs that are moving between interconnected SNPNs NOTE: It is assumed the interconnected SNPNs have overlapping radio coverage	[PR 5.4.6-002] [PR 5.4.6-003] [PR 5.4.6-004]

6.2 Consolidated requirements for enabling of SNPN cellular hotspots p. 19

The potential requirements for enabling of SNPN cellular hotspots correspond to the use case in clause 5.1 (Scalable SNPN Interconnect with dynamic connections) and are listed in Table 6.2-1.

The requirements for SNPN cellular hotspots are intended to enable support of connectivity hotspots based on 3GPP 5G network that provide services in a similar way as provided by WLAN hotspots. Charging requirements are considered out of scope for this functionality.

CPR #	Consolidated Potential Requirement	Original PR #	Comment
CPR 6.2-1	Based on the Standalone Non-Public Network (SNPN) configuration, the 5G network shall support a mechanism for an SNPN to be able to interconnect with a large number of SNPN Credential Providers with which the SNPN might not have preconfigured information detailing the IP addresses used by these SNPN Credential Providers to interconnect with the SNPN.	[PR 5.1.6-001]	Scalability
CPR 6.2-2	Based on the Standalone Non-Public Network (SNPN) configuration, the 5G network shall support a mechanism for an SNPN Credential Provider to be able to interconnect with a large number of Standalone Non-Public Networks (SNPNs) with which the SNPN Credential Provider might not have preconfigured information detailing the IP addresses used by these SNPNs to interconnect with the SNPN Credential Provider.	[PR 5.1.6-002]	Scalability
CPR 6.2-3	Based on the Standalone Non-Public Network (SNPN) configuration, the 5G network shall support a mechanism for an SNPN to be able to determine how to connect to an SNPN Credential Provider capable of verifying the identity presented by a user attempting to connect to that SNPN.	[PR 5.1.6-003]
CPR 6.2-4	Based on the Standalone Non-Public Network (SNPN) configuration, the 5G network shall support a mechanism for an SNPN to be able to securely interconnect with an SNPN Credential Provider in deployments where the required security information is not preconfigured.	[PR 5.1.6-004]	Security
CPR 6.2-5	Based on the Standalone Non-Public Network (SNPN) configuration, the 5G network shall support a mechanism for an SNPN to enable an SNPN Credential Provider to securely notify events (e.g., a user's subscription ending) to the Standalone Non-Public Network (SNPN).	[PR 5.1.6-005]	Security

7 Conclusions and recommendations p. 20

This technical report identifies several use cases and potential new requirements related to the interconnect of SNPNs with two aspects:

Groups of interconnected SNPNs.
Enabling of SNPN cellular hotspots (Scalable SNPN Interconnect with dynamic connections).

The resulting service requirements have been consolidated in clause 6.

It is recommended to consider the consolidated requirements identified in this TR as the baseline for the subsequent normative work.
