22.2633GPPRelease 17Service requirements for Video, Imaging and Audio for Professional Applications (VIAPA)TS
5.1 Non-public network requirements
The 5G system enables an NPN for video, imaging and audio for professional applications. The related requirements are described in 3GPP TS 22.261 [4]:
– Generic NPN requirements can be found in clause 6.25.
– Requirements on the subscription aspects can be found in clause 6.14.
– Authentication requirements can be found in clause 8.3.
5.2 Application specific requirements
The 5G system shall support media flows from open standard based broadcast workflows and be agnostic to the data carried.
5.3 Clock synchronization
The 5G network shall be able to provide a time reference information to a 3rd party application acting as a master clock with an accuracy of 1 microsecond.
5.4 Network exposure requirements
The 5G system shall support mechanisms to allow 3rd party application to update information associated to UE configuration (e.g. media compression, resolution, frame rate) for a UE or group of UEs using the application.
5.5 Service continuity
The 5G system shall be able securely reconnect within a short period of time (<1s) from UE starting first network reconnection attempt after the UE has detected a UE network connection loss.
The 5G system shall support uplink and downlink service continuity maintaining acceptable performance requirements while switching between co-located PLMN and NPN (e.g., due to mobility).
The 5G system shall support service continuity maintaining acceptable performance requirements: for an uplink stream while performing traffic steering, switching, and splitting among co-located PLMN(s) and NPN(s); for downlink while switching between co-located PLMN and NPN.
5.6 Multi-network connectivity and service delivery
The 3GPP system shall be able to enable a UE to receive low-latency downlink multicast traffic from one network (e.g. NPN), and paging as well as data services from another network (e.g. PLMN) simultaneously.
NOTE: Depending on the capabilities and configurations of the UE, limitations of data-rate and latency may be acceptable.
