[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The embodiment of the present invention provides an embodiment of a quality of service communication method. It should be noted that although a logical sequence is shown in the flow chart, under certain data, the steps shown or described may be completed in an order different from that shown here.

[0038] Reference Figure 1 , Figure 1 : is a flow chart of the quality service communication method provided by the present invention. The quality service communication method provided by the embodiment of the present invention includes:

[0039] Step 101, establishing a communication connection between the wireless push-to-talk cluster service system and the policy control module;

[0040] Step 102, establishing a quality of service flow based on the policy control module and the communication connection;

[0041] Step 103: Perform call communication based on the quality of service flow.

[0042] It should be noted that the embodiment of the present invention takes a quality service communication system as an example of an execution subject, and the quality service communication system is one type of cluster scheduling system.

[0043] Specifically, the quality service communication system controls the newly added interface of the wireless one-touch cluster service system (POC, PTT OverCellular) to establish a communication connection with the interface of the 5G policy control module (PCF, Policy Control Function).

[0044] Furthermore, the quality service communication system controls the 5G policy control module PCF to send a message to the 5G session management module (SMF, Session Management Function) to establish a quality service flow QoS Flow through the communication connection between the wireless one-button cluster service system POC Server and the 5G policy control module PCF.

[0045] Furthermore, the quality service communication system performs call communication through the quality service flow QoS Flow, that is, establishes a 5G session through the quality service flow QoS Flow.

[0046] The quality service communication method provided by the present invention establishes a communication connection between a wireless push-to-talk cluster service system and a policy control module; establishes a quality service flow based on the policy control module and the communication connection; and performs call communication based on the quality service flow. In the process of quality service communication, an end-to-end call communication with a quality service flow is established through the communication connection between the wireless push-to-talk cluster service system and the policy control module, thereby improving the communication quality of the wireless push-to-talk cluster service system.

[0047] Furthermore, the establishment of a communication connection between the push-to-talk over wireless cluster service system and the policy control module as recorded in step 101 includes:

[0048] Controlling the wireless push-to-talk cluster service system to send a policy authorization creation request to the policy control module;

[0049] The policy control module is controlled to return a policy authorization creation response to the wireless push-to-talk cluster service system according to a message body carried in the policy authorization creation request, so as to establish a communication connection between the wireless push-to-talk cluster service system and the policy control module.

[0050] Specifically, the wireless push-to-talk cluster service system POC Server sends a policy authorization creation request to the 5G policy control module PCF, where the policy authorization creation request can be expressed as Npcf_PolicyAuthorization_CreateRequest. After the 5G policy control module PCF receives the policy authorization creation request Npcf_PolicyAuthorization_Create Request sent by the wireless push-to-talk cluster service system POC Server, it parses the policy authorization creation request Npcf_PolicyAuthorization_Create Request to obtain the message body carried in the policy authorization creation request Npcf_PolicyAuthorization_Create Request, where the message body can be AppSessionContextReqData.

[0051] The 5G policy control module PCF returns a policy authorization creation response to the wireless one-key cluster service system POC Server according to the AppSessionContextReqData message body, where the policy authorization creation response can be Npcf_PolicyAuthorization_Create Response.

[0052] After the wireless push-to-talk cluster service system POC Server receives the policy authorization creation response Npcf_PolicyAuthorization_Create Response returned by the 5G policy control module PCF, a communication connection is established between the interface of the wireless push-to-talk cluster service system POC Server and the interface of the 5G policy control module PCF.

[0053] The embodiment of the present invention establishes a communication connection through the interface of the wireless one-push talk cluster service system and the interface of the 5G policy control module PCF. Therefore, the 5G network does not need to be modified end to end, thereby improving feasibility.

[0054] Further, the establishment of a quality of service flow based on the policy control module and the communication connection as recorded in step 102 includes:

[0055] The policy control module is controlled based on the communication connection to send a policy control update request to a session management module to establish the quality of service flow.

[0056] Specifically, the quality service communication system controls the 5G policy control module PCF to send a policy control update request to the 5G session management module SMF through the communication connection between the wireless one-push-to-talk cluster service system POC Server and the 5G policy control module PCF, wherein the policy control update request may be Npcf_SMPolicyControl_UpdateNotify. Further, after the 5G session management module SMF receives the policy control update request Npcf_SMPolicyControl_UpdateNotify sent by the 5G policy control module PCF, it triggers the bearer establishment to establish a quality service flow QoS Flow with the user terminal (UE, User Equipment).

[0057] Furthermore, the quality service flow includes a voice quality service flow and a video quality service flow.

[0058] A voice quality service flow and a video quality service flow are established based on the policy control module and the communication connection.

[0059] Therefore, it can be understood that the quality service communication system controls the 5G policy control module PCF to send a policy control update request Npcf_SMPolicyControl_UpdateNotify to the 5G session management module SMF through the communication connection between the wireless one-button cluster service system POC Server and the 5G policy control module PCF.

[0060] Furthermore, after the 5G session management module SMF receives the policy control update request Npcf_SMPolicyControl_UpdateNotify sent by the 5G policy control module PCF, it triggers the bearer to establish a voice quality service flow QoS Flow and a video quality service flow QoS Flow with the user terminal UE, wherein the voice quality service flow QoS Flow can be defined as 5QI=1, and the video quality service flow QoS Flow can be defined as 5QI=2.

[0061] The embodiment of the present invention establishes a voice quality service flow and a video quality service flow, thereby improving the voice quality service and video quality service of the wireless push to talk cluster service system.

[0062] The call communication based on the quality service flow recorded in step 103 includes: active call communication based on the voice quality service flow and the video quality service flow.

[0063] Specifically, refer to Figure 2 , Figure 2 This is a flow chart of active communication of quality service flow provided by the present invention. Before initiating a call, the user terminal UE needs to be in the connection management-connected state (CM-CONNECTED). The user terminal UE initiates a call and sends a SIP INVITE message to the POC Server of the push-to-talk over cellular cluster service system.

[0064] Furthermore, after receiving the SIP INVITE message sent by the user terminal UE, the Push to Talk over Cellular cluster service system POC Server returns SIP 100 Trying.

[0065] Furthermore, the wireless push-to-talk cluster service system POC Server sends a policy authorization creation request Npcf_PolicyAuthorization_Create Request message to the 5G policy control module PCF.

[0066] The 5G policy control module PCF receives the policy authorization creation request Npcf_PolicyAuthorization_Create Request message sent by the wireless one-button cluster service system POC Server, parses the policy authorization creation request Npcf_PolicyAuthorization_Create Request message, and obtains the AppSessionContextReqData message body carried in the policy authorization creation request Npcf_PolicyAuthorization_Create Request message.

[0067] Furthermore, the 5G policy control module PCF returns a policy authorization creation response Npcf_PolicyAuthorization_Create Response message to the wireless one-push to talk cluster service system POC Server.

[0068] Furthermore, the 5G policy control module PCF sends a policy control update request Npcf_SMPolicyControl_UpdateNotify message to the 5G session management module SMF, triggering the establishment of voice quality service flow QoS Flow and video quality service flow QoS Flow, with 5QI=1 for the voice quality service flow QoS Flow and 5QI=2 for the video quality service flow QoS Flow.

[0069] Furthermore, after the SIP signaling 183, 180, 200, and ACK messages are exchanged, the call channel is established, and the calling party and the called party can communicate through the voice quality service flow QoS Flow and the video quality service flow QoS Flow.

[0070] The call communication based on the quality service flow recorded in step 103 includes: performing passive call communication based on the voice quality service flow and the video quality service flow.

[0071] Specifically, refer to Figure 3 , Figure 3 It is a flowchart of passive communication of quality service flow provided by the present invention. The push-to-talk over cellular cluster service system POC Server sends a SIP INVITE message to the user terminal UE, and the SIP INVITE message first reaches the user function module (UPF, User Plane Function).

[0072] If the user terminal UE is in the connection management-connected state (CM-CONNECTED), the user function module UPF directly forwards the SIP INVITE message to the user terminal UE.

[0073] If the user terminal UE is in the connection management-idle state CM-IDLE state, the 5G core network (5GC) initiates the Paging process, and the user terminal UE initiates the Service Request process and enters the CM-CONNECTED state.

[0074] Furthermore, after receiving the SIP INVITE message, the user terminal UE returns 100Trying to the Push to Talk over Cellular cluster service system POCServer.

[0075] Furthermore, the wireless push-to-talk cluster service system POC Server sends a policy authorization creation request Npcf_PolicyAuthorization_Create Request message to the 5G policy control module PCF.

[0076] The 5G policy control module PCF receives the policy authorization creation request Npcf_PolicyAuthorization_Create Request message sent by the wireless one-button cluster service system POC Server, parses the policy authorization creation request Npcf_PolicyAuthorization_Create Request message, and obtains the AppSessionContextReqData message body carried in the policy authorization creation request Npcf_PolicyAuthorization_Create Request message.

[0077] Furthermore, the 5G policy control module PCF returns a policy authorization creation response Npcf_PolicyAuthorization_Create Response message to the wireless one-push to talk cluster service system POC Server.

[0078] Furthermore, the 5G policy control module PCF sends a policy control update request Npcf_SMPolicyControl_UpdateNotify message to the 5G session management module SMF, triggering the establishment of voice quality service flow QoS Flow and video quality service flow QoS Flow, with 5QI=1 for the voice quality service flow QoS Flow and 5QI=2 for the video quality service flow QoS Flow.

[0079] Furthermore, after the SIP signaling 183, 180, 200, and ACK messages are exchanged, the call channel is established, and the calling party and the called party can communicate through the voice quality service flow QoS Flow and the video quality service flow QoS Flow.

[0080] It should be noted that, in addition to voice quality service flow QoS Flow and video quality service flow QoS Flow, the embodiment of the present invention is applicable to other IP applications that require quality service QoS guarantee according to actual conditions, such as data services in POC and other business systems.

[0081] The present invention enables the calling and called parties to simultaneously establish a voice quality service flow QoS Flow and a video quality service flow QoS Flow, thereby reducing the call establishment delay.

[0082] Furthermore, the quality service communication system provided by the present invention and the quality service communication method provided by the present invention correspond to each other.
