Example URSP rules | Comments | |
---|---|---|
Rule Precedence =1 Traffic Descriptor: Application descriptor=App1 | Route Selection Descriptor Precedence=1 Network Slice Selection: S-NSSAI-a SSC Mode Selection: SSC Mode 3 DNN Selection: internet Access Type preference: 3GPP access | This URSP rule associates the traffic of application "App1" with S-NSSAI-a, SSC Mode 3, 3GPP access and the "internet" DNN. It enforces the following routing policy: The traffic of App1 should be transferred on a PDU Session supporting S-NSSAI-a, SSC Mode 3 and DNN=internet over 3GPP access. If this PDU Session is not established, the UE shall attempt to establish a PDU Session with S-NSSAI-a, SSC Mode 3 and the "internet" DNN over 3GPP access. |
Rule Precedence =2 Traffic Descriptor: Application descriptor=App2 | Route Selection Descriptor Precedence =1 Network Slice Selection: S-NSSAI-a Access Type preference: Non-3GPP access | This URSP rule associates the traffic of application "App2" with S-NSSAI-a and Non-3GPP access. It enforces the following routing policy: The traffic of application App2 should be transferred on. a PDU Session supporting S-NSSAI-a using a Non-3GPP access. If this PDU Session is not established, the UE shall attempt to establish a PDU Session with S-NSSAI-a over Access Type=non-3GPP access. If the PDU Session cannot be established, the traffic of App2 shall be directly offloaded to WLAN, if the UE is connected to a WLAN with SSID-a (based on the 2nd RSD) |
Route Selection Descriptor Precedence =2 Non-seamless Offload indication: Permitted (WLAN SSID-a) | ||
Rule Precedence =3 Traffic Descriptor: DNN=DNN_1 | Route Selection Descriptor Precedence =1 Network Slice Selection: S-NSSAI-a Access Type preference: Non-3GPP access | This URSP rule associates the traffic of applications that are configured to use DNN_1 with DNN_1, S-NSSAI-a over Non-3GPP access. It enforces the following routing policy: The traffic of application(s) that are configured to use DNN_1 should be transferred on a PDU Session supporting S-NSSAI-a over Non-3GPP access. If this PDU Session is not established, the UE shall attempt to establish the PDU Session with S-NSSAI-a over Non-3GPP access. |
Rule Precedence =4 Traffic Descriptor: Application descriptor=App1 Connection Capabilities="internet", "supl" | Route Selection Descriptor Precedence =1 Network Slice Selection: S-NSSAI-a DNN Selection: DNN_1 Access Type preference: Non-3GPP access | This URSP rule associates the application "App1" and the Connection Capabilities "internet" and "supl" with DNN_1, S-NSSAI-a over Non-3GPP access. It enforces the following routing policy: When the "App1" requests a network connection with Connection Capability "internet" or "supl", the UE establishes (if not already established) a PDU Session with DNN_1 and S-NSSAI-a over Non-3GPP access. After that, the UE routes the traffic of "App1" over this PDU Session. |
Rule Precedence =5 Traffic Descriptor: Application descriptor=App3 Connection Capabilities="ims" | Route Selection Descriptor Precedence =1 Network Slice Selection: S-NSSAI-c DNN Selection: DNN_1 Access Type preference: Multi-Access | This URSP rule associates the application "App3" and the Connection Capability "ims" with DNN_1, S-NSSAI-c and multi-access connectivity. It enforces the following routing policy: When the "App3" requests a network connection with Connection Capability "ims", the UE establishes (if not already established) a MA PDU Session with DNN_1 and S-NSSAI-c. After that, the UE routes the traffic of "App3" over this MA PDU Session by using the received ATSSS rules |
Rule Precedence =6 Traffic Descriptor: Application descriptor=App1 | Route Selection Descriptor Precedence =1 DNN Selection: DNN_1 Network Slice Selection: S-NSSAI-a Access Type preference: Multi Access | This URSP rule associates App 1 with DNN_1, S-NSSAI-a with Multi Access connectivity. It enforces the following routing policy: The traffic of Application 1 should be transferred on a PDU Session supporting S-NSSAI-a and DNN_1 according to the received ATSSS rules. After that the UE routes the traffic of any other application according to the ATSSS rule with match all packet filters if available. |
Rule Precedence =7 Traffic Descriptor: Connection Capabilities="Real time interactive" | Route Selection Descriptor Precedence =1 Network Slice Selection: S-NSSAI-d Access Type preference: 3GPP-Access | This URSP rule associates the Connection Capability "Real time interactive" with S-NSSAI-d and 3GPP-access connectivity. It enforces the following routing policy: When any application requests a network connection with Connection Capability "Real time interactive", the UE establishes (if not already established) a PDU Session with S-NSSAI-d over 3GPP access. After that, the UE routes the traffic from the requesting application over this PDU Session. |
Rule Precedence = lowest priority Traffic Descriptor: * | Route Selection Descriptor Precedence =1 Network Slice Selection: S-NSSAI-b SSC Mode Selection: SSC Mode 3 DNN Selection: internet | This URSP rule associates all traffic not matching any prior rule a PDU Session with S-NSSAI-b, SSC Mode 3 and the "internet" DNN. It enforces the following routing policy: All traffic not matching any prior rule should be transferred on a PDU Session supporting S-NSSAI-b, SSC Mode 3 and DNN=internet with no access network preference. |
