[0002] Voice over New Radio (VoNR) is a voice service based on the fifth generation (5G) mobile communication technology, that is, New Radio (NR) users can perform voice services based on the NR network. VoNR+ technology is equipped with a new data transmission channel based on VoNR to provide users with richer real-time interactive services. With the development of 5G VONR multimedia real-time communication technology, VONR technology has gradually evolved to functions such as ultra-high-definition video calls and remote assistance, and the demand for network resources is increasing.

[0003] Related VONR+ services and VONR services are deployed on the same user plane function (UPF). However, when VONR+ services are deployed on ordinary UPF, the large demand for network resources by VONR+ has an impact on the current UPF network, resulting in low resource utilization and high network deployment costs. Summary of the invention

On the second hand, in the subsequent UPF transformation, only the first UPF can be transformed as appropriate to avoid increasing the cost of subsequent UPF deployment or transformation.

[0021] Figure 2 1 is a flow chart of a method for processing voice carried by a new air interface provided by an embodiment of the present application. As shown in the figure, the method includes the following steps:

[0022] S21: When the first user plane function UPF detects a service request of the second new air interface to carry voice VoNR, the second UPF responds to the service request of the second VoNR.

[0023] The first UPF is used to provide a service of a first VoNR, and the network resources required for the service of the first VoNR are less than the network resources required for the service of the second VoNR.

[0024] For example, the first VoNR service may include VoNR service, and the second VoNR service may include VoNR+ service, and the network resources required for VoNR service are less than those required for VoNR+ service. In other words, VoNR service can be provided through the first UPF, and VoNR+ service can be provided through the second UPF. The UPF providing VoNR service and the UPF providing VoNR+ service can be separated, and only a separate UPF is used to deploy VONR+ service. A VONR+ private network can be built, and the private network is dedicated. Therefore, on the one hand, the high demand for network resources of VONR+ can be avoided from impacting the first UPF. On the second hand, in the subsequent UPF transformation, only the first UPF can be transformed according to the situation to avoid the subsequent UPF transformation cost being raised. On the third hand, it is avoided to deploy unnecessary VONR+ services on the first UPF, resulting in waste of resources on the first UPF.

[0025] In one implementation, before S21, a first detection rule for the service request of the second VoNR can also be set on the first UPF, and the first detection rule includes: the service application identifier and start event of the second VoNR; a packet detection rule (Packet Detection Rule, PDR) that generates the first detection rule; when the first UPF detects a request data stream matching the PDR, it is determined that the first UPF detects a service request for the second new air interface to carry voice VoNR. Therefore, when the user is performing a VONR service, the VONR+ function service is turned on due to need, and the first UPF can detect the request data matching the PDR.

[0026] Figure 3 1 is a flow chart of a method for processing voice carried by a new air interface provided by an embodiment of the present application. As shown in the figure, the method includes the following steps:

[0027] S301: A user of a second VoNR service establishes a session.

[0028] A UE that has signed up for the VONR+ service establishes a session under 5G.

[0029] S302: When a user of the second VoNR service makes a voice call, a dedicated bearer for the voice call is established.

[0030] The UE needs to make a voice call and starts to establish dedicated bearer resources.

[0031] S303: Send voice dedicated bearer rules through PCF.

[0032] Through PCF, a first detection rule for issuing VONR+ service can be constructed while establishing a dedicated bearer. The first detection rule includes: a service application ID and a start event of the second VoNR. A first detection rule for the service request of the second VoNR is set on the first UPF, and a data packet detection rule PDR of the first detection rule is generated. When the first UPF detects a request data flow matching the PDR, it is determined that the first UPF detects a service request of the second new air interface to carry voice VoNR, for example, the user's VONR+ service request data flow matches the detection rule PDR of the VONR+ service, such as Figure 1 The PSA1 pathway is shown in Figure 2.

[0033] S304. Establish dedicated bearer resources on PSA1 and send detection rules to the first UPF to detect VONR+ service data flow.

[0034] If the user needs to report the use of VONR+ services, the detection rules and dedicated carrier rules will be sent to the same UPF of PSA1 through SMF.

[0035] S305: UE voice dedicated bearer is established.

[0036] S306. The UE needs to use the VONR+ function based on VONR according to its own needs and turn on the VONR+ function.

[0037] S307. VONR+ data flow is detected on PSA1.

[0038] S308. Report to SMF.

[0039] PSA1 detects VONR+ data flow and reports it to SMF.

[0040] In S306-S308, when the first UPF detects the service request of the second VoNR for starting the service of the second VoNR, the service request of the second VoNR is reported to the SMF through the first UPF. This embodiment of the application requires that PSA1 detects the request data stream that matches the detection PDR, that is, reports to the SMF after identifying the VONR+request data stream, and establishes the service resources of the second VoNR on the second UPF through the SMF, and the service resources of the second VoNR are used to respond to the service request of the second VoNR.

[0041] S309. SMF reports to PCF based on the detection information reported by PSA1.

[0042] S310. PCF decides to issue VONR+ business rules.

[0043] S311. SMF completes UPF selection based on the diverted DNAI information.

[0044] S312. Establish VONR+ service resources on PSA2.

[0045] In S309-S312, the service request of the second VoNR is sent to the packet control function PCF through the SMF; the diversion service rules of the service request of the second VoNR are allocated through the PCF, such as VONR+ service rules, and the diversion service rules carry a stop event and a data network access identifier (DN Access Identifier, DNAI).

[0046] In one implementation, the DNAI carried by the first service rule and the diversion service rule is the same, ensuring that both are loaded on the same UPF. Loading the second UPF requires finding the forwarding action rules (FAR) corresponding to the diversion service rule DNAI and monitoring the PDR associated with the found FAR. The SMF selects the second UPF according to the diversion service rule; and establishes the service resources of the second VoNR on the second UPF through the SMF.

[0047] Through the above steps, on the one hand, the impact of VONR+'s high demand for network resources on the first UPF can be avoided. On the other hand, in the subsequent UPF transformation, only the first UPF can be transformed according to the situation to avoid the subsequent UPF transformation cost being raised. On the third hand, it is avoided to deploy non-essential VONR+ services on the first UPF, which causes waste of resources on the first UPF. Fourthly, the three major network elements of PCF, SMF and UPF cooperate to allocate VONR+ service resources according to the actual needs of users, allowing users to flexibly switch between VONR services and VONR+ services, reducing UPF resource waste and improving UPF utilization. Fifthly, the creation time of VONR+ service resources is optimized.

[0048] S313: Uninstall the first detection rule.

[0049] The VONR+ service will not be matched to PSA1. That is, the PCF allocates the diversion service rules of the service request of the second VoNR and notifies to uninstall the first detection rule. After the service resources of the second VoNR are established on the second UPF through the SMF, the first detection rule on the first UPF is uninstalled.

[0050] S314. The user uses the VONR+ service through PSA2.

[0051] S315. Due to personal needs, the user turns off the VONR+ service during this call and only uses the VONR voice call.

[0052] S316. PSA2 detects that the VONR+ service data flow does not appear within a certain period of time and determines that the VONR+ service data flow has stopped.

[0053] That is, when the second UPF detects that the stop time of the PDR data flow exceeds the time threshold, it is determined that the second UPF detects that the service flow of the second VoNR has stopped.

[0054] S317. PSA2 reports the detection information to SMF.

[0055] S318. Report to PCF.

[0056] SMF reports the detection information reported by PSA2 to PCF.

[0057] S319. PCF decides to unload VONR+ business rules.

[0058] In S315-S319, when the service flow of the second VoNR is detected to be stopped by the second UPF, the service stop request is sent to the SMF by the second UPF. The service resources of the second VoNR are unloaded on the second UPF by the SMF, and the service resources of the second VoNR are used to respond to the service request of the second VoNR.

[0059] Among them, unloading the service resources of the second VoNR on the second UPF through the SMF includes: sending the service stop request to the PCF through the SMF; allocating the unloading service rules of the service request of the second VoNR through the PCF, and the unloading service rules carry DNAI and stop events; unloading the service resources of the second VoNR on the second UPF through the SMF according to the unloading service rules.

[0060] Allocating the unloading service rule of the service request of the second VoNR through the PCF includes: allocating the unloading service rule of the service request of the second VoNR and the second detection rule of the service request of the second VoNR through the PCF, and notifying the unloading of the diversion service rule, the second detection rule includes: the service application identifier (application ID) of the second VoNR and the start event. The second detection rule is loaded on the main anchor point PSA1.

[0061] S320. SMF deletes resources on PSA2.

[0062] Through the above steps S315-S320, on the one hand, when the service flow of the second VoNR stops, network resources are released in time to avoid waste of network resources. On the other hand, the three major network elements PCF, SMF and UPF cooperate to allocate VONR+ service resources according to the actual needs of users, so that users can flexibly switch between VONR services and VONR+ services, reduce UPF resource waste, and improve UPF utilization rate. Thirdly, the release timing of VONR+ service resources is optimized.

[0063] S321. Establish VONR+ business detection rule resources.

[0064] The second detection rule is established on the first UPF through the SMF, and the service request of the second VoNR is detected through the first UPF; the diversion service rule on the second UPF is unloaded through the SMF.

[0065] The embodiment of the present application requires that when a user stops using the VONR+ service, relevant VONR+ service detection rules be established on the main anchor point PSA1, so that the next time the user terminal requests the VONR+ service, it can be detected, triggering the reconstruction of VONR+ service resources.

[0066] S322. The user conducts VONR dedicated voice communication on PSA1.

[0067] Figure 4 The structure diagram of the device for processing voice carried by a new air interface according to an embodiment of the present application is provided. As shown in the figure, the device 400 includes: a processing module 410.

[0068] The processing module 410 is used to respond to the service request of the second new air interface carrying voice VoNR through the second UPF when the first user plane function UPF detects the service request of the second VoNR; the first UPF is used to provide the service of the first VoNR, and the network resources required for the service of the first VoNR are less than the network resources required for the service of the second VoNR.

[0069] In one implementation, the apparatus 400 further includes a determination module for determining a second UPF.

[0070] In one implementation, the processing module 410 is used to set a first detection rule for the service request of the second VoNR on the first UPF before responding to the service request of the second VoNR through the second UPF when the first user plane function UPF detects a service request of the second VoNR carrying voice. The first detection rule includes: a service application identifier and a start event of the second VoNR; generating a data packet detection rule PDR of the first detection rule; and determining that the first UPF has detected a service request of the second new air interface carrying voice VoNR when the first UPF detects a request data flow matching the PDR.

[0071] In one implementation, the processing module 410 is used to report the service request of the second VoNR to the session management function SMF through the first UPF when the first UPF detects a service request of the second VoNR for starting the service of the second VoNR; establish the service resources of the second VoNR on the second UPF through the SMF, and the service resources of the second VoNR are used to respond to the service request of the second VoNR.

[0073] In one implementation, the processing module 410 allocates the diversion service rules of the service request of the second VoNR through the PCF, including: allocating the diversion service rules of the service request of the second VoNR through the PCF, and notifying the unloading of the first detection rule; after the processing module 410 establishes the service resources of the second VoNR on the second UPF through the SMF, the first detection rule on the first UPF is unloaded.

[0074] In one implementation, when the processing module 410 detects that the service flow of the second VoNR has stopped through the second UPF, the processing module 410 sends the service stop request to the SMF through the second UPF; the service resources of the second VoNR are unloaded on the second UPF through the SMF, and the service resources of the second VoNR are used to respond to the service request of the second VoNR.
