5G/NR - VoNR  

 

 

 

VoNR  (Voice Over NR)

VoNR is very similar to VoLTE. They are all based on Voice call over IMS. The main difference is that the IMS is established by and go through 5G Core network in VoNR whereas it is established by and go through 4G core network. Even in terms of 3GPP, the details of VoNR procedure is described in 23.228 which is mainly for IMS for LTE and 5G specific details are provided as an appendix (Annex Y). So if you are already familiar with VoLTE, you would catch up VoNR very quickly and most of the contents listed in my IMS notes would applies to VoNR as well. In this page, I would mostly focus on the differences in VoNR.

Overall Call Flow

Following is the overall call flow of NR. You would see a little bit of differences in terms of signaling message name comparing to VoLTE setup, but those differences are due to signaling difference between LTE and NR, not specifically due to IMS side difference. I wouldn't put all the details of NR signaling procedure here. I would only put those steps related to VoNR.

PDU session establishment request (Log shared by Amarisoft)

This is the message from UE that initiate setting up the configuration which are required to do IMS registration. I would like you to note that this message is requesting a PDU setup with DNN="ims" and requesting the IP address for P-CSCF.  If you are familiar with VoLTE process, you would notice that the role of this message is similar to PDN Connectivity Request in VoLTE.

Once network recieves the PDU session establishment request message from UE, Network informs the UE of the requested information (P-CSCF) and creates a QoS pipe that is necessary for the traffic. This is similar to Activate default EPS bearer context request in VoLTE.

PDU session modification command (Log shared by Amarisoft)

Once IMS registration is done and the user trigger IMS call, it would reach a certain point where another data pipe for IMS data traffic (i.e, Voice traffic). For setting up the data only traffic (not IMS signaling), usually NW sets up another data pipe (QoS flow) dedicated for the data traffic. This process is initiated by NW via PDU session modification command (NOTE : Even though this step is done in most of the real network implementation for IMS service, it is not mandatory in protocol point of view. In other words, you may implement the service in such a way that both IMS signaling and voice data go through the single data pipe). This is similar to Activate dedicated EPS bearer context request in VoLTE.

QoS Flow

In VoNR, two different data flows get involved and in most case these two flows are mapped to two different types of QoS pipe. Following is a typical example of the two QoS pipe being used in VoNR based on the log shared by Amarisoft. If you are not familiar with 5G QoS Structure, it would be worth reading my notes on 5G QoS first.

The first QoS Pipe is involved mostly in setting up the data flow for IMS signaling message as shown in the following example. Usually, this QoS setup is triggered by UE via PDU Session Establishment Request and Network creates a core network side of the QoS flow via PDU Session Establishment Accept message. This core network side of QoS pipe (QoS Flow) is mapped to RAN(Radio Access Network) pipe through SDAP configuration in Rrc Message as shown below.

The second QoS Pipe is involved mostly in setting up the data flow for IMS traffic (Voice data) as shown in the following example. This QoS setup is triggered by Network via PDU Session Modification Command and Network creates another QoS pipe on core network side. This core network side of QoS pipe (QoS Flow) is mapped to RAN(Radio Access Network) pipe through SDAP configuration in Rrc Message as shown below.

S1 mode vs N1 mode

  •   S1 mode :  indicates successful EPS Attach
  •   N1 mode : indicates successful 5GC(5G Core) Attach

Key Informations in Signaling Message

There are many different types of message with various information elements related to VoNR service and I am trying to list up those messages and information elements in this section. But I wouldn't say all of these information elements are mandatory. Depending on Network implementation or UE protocol stack implementation it may work without some of these informations.
