Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a method, apparatus and communication equipment for quality of service assurance. Background Technology

[0002] With the emergence of time-sensitive services, such as XR terminals (i.e., VR / AR, Virtual Reality / Augmented Reality), the demand for end-to-end latency assurance has increased. However, traditional latency assurance is statically segmented, with each segment being guaranteed independently, and the communication network only guaranteeing one segment. But the computation latency within the server and within the terminal has a certain degree of scalability depending on different services, computational requirements, and terminal capabilities. Therefore, statically dividing the latency between the terminal and the gateway is not flexible enough. How to improve end-to-end service-level QoS assurance is a technical problem that urgently needs to be solved. Summary of the Invention

[0167] like Figure 2A and Figure 2B As shown, end-to-end service-level latency can be divided into first latency, second latency, third latency, and fourth latency.

[0168] like Figure 2A As shown, the first latency information includes: latency information between the terminal-side data terminal and the terminal. The terminal-side data terminal can be located inside or outside the terminal. The latency between the terminal-side data terminal and the terminal includes the time required for data to travel between the terminal-side data terminal and the terminal.

[0169] The third latency information includes: latency information between the gateway and the network-side data terminal, and latency information between the communication network and the network-side data terminal.

The latency between the communication network and the network-side data terminal includes the time required for data to travel between the communication network and the network-side data terminal. The gateway can be a gateway within the communication network. The gateway includes at least one of the following: UPF (such as PSA).

[0170] The fourth latency information includes: latency information within the network-side data terminal. This latency information includes the time required for data to travel within the network-side data terminal.

[0171] like Figure 2A and 2BThe second delay information shown includes one of the following: delay between the terminal and the gateway, and transmission delay within the communication network. The delay between the terminal and the gateway includes the time required for data to travel between the terminal and the gateway.

[0172] like Figure 2B As shown, the first latency information includes: intra-terminal latency information. The intra-terminal latency information includes the time required for data to travel through the terminal.

[0173] The third latency information includes one of the following: latency between the gateway and the server, and latency between the communication network and the server. The latency between the gateway and the server includes the time required for data to travel between the gateway and the server. The latency between the communication network and the server includes the time required for data to travel between the communication network and the server. The gateway can be a gateway within the communication network. The gateway includes at least one of the following: a UPF (such as a PSA).

[0174] The fourth latency information includes one of the following: server-internal latency information. The server-internal latency includes the time required for data to travel within the server.

[0175] Scenario 1: With the emergence of time-sensitive services, such as XR terminals (i.e., VR / AR, Virtual Reality / Augmented Reality), the demand for end-to-end latency assurance has increased. However, traditional latency assurance is statically segmented, with each segment being guaranteed independently. The communication network is generally responsible for guaranteeing the second latency. For example, the end-to-end service-level latency of an XR service is 50ms, while the latency in the communication network (such as the transmission latency between the terminal and the gateway) only accounts for 10ms. However, the computation latency within the server and the computation latency within the terminal have a certain degree of scalability depending on the service, computational requirements, and terminal capabilities. Therefore, even if the second latency is guaranteed, the overall end-to-end service-level latency may not meet the requirements (e.g., exceeding 50ms); or even if the second latency guarantee fails (e.g., exceeding 10ms), the overall end-to-end service-level latency may still meet the requirements (e.g., within 50ms).

[0176] Scenario 2: With the emergence of cloud computing, distributed computing may exist between the client and the server. That is, some computing is performed on the UE, while other computing is performed on the server, or all computing is offloaded to the server. In this case, there is a correlation between the first latency and the fourth latency. The division between the first latency and the fourth latency is not static but related to the business logic.

[0177] Therefore, the following problems need to be addressed:

[0178] Question 1:

[0179] Static latency segmentation guarantees lack flexibility and cannot meet the requirements for high-precision end-to-end latency guarantees. Improving end-to-end latency guarantees for services is a pressing technical problem. With the edge computing of servers, the network and server-based service cloud are becoming integrated, making it possible to manage and controllable the first latency (e.g., latency within the UE), the second latency (e.g., latency between the UE and the gateway), the third latency (latency between the gateway and the server), and the fourth latency (latency within the server).

[0180] One approach is that, assuming the first and third delays are relatively stable, the second and fourth delays can influence each other's values. For example, increasing the fourth delay can decrease the second delay. The second delay can also affect the budget for the fourth delay.

[0181] Question 2:

[0182] End-to-end service-level latency guarantees undoubtedly require more signaling control and resource scheduling; therefore, they should only be applicable to certain services and certain UEs.

[0183] One solution is to restrict services and user experience (UE) based on subscription information.

[0184] Another solution is to make the request through the UE or a third-party proxy (such as AF).

[0185] Question 3:

[0186] For some latency-sensitive services, if end-to-end service-level latency guarantees cannot be successfully implemented, it may be unnecessary to initiate the service.

[0187] One solution is to send the service only after the end-to-end service-level latency guarantee is successful.

[0188] In one embodiment of the present invention, the fourth latency (e.g., server-level latency) = service-level latency, the first latency (e.g., UE-level latency) - the second latency - the third latency.

[0189] In one embodiment of the present invention, the second delay = service-level delay - first delay (such as UE-internal delay) - third delay - fourth delay.

[0190] In one embodiment of the present invention, the second delay can be the intra-communication network delay, or the delay between the terminal and the gateway. The intra-communication network delay indicates the time required for data to be forwarded within the communication network.

[0191] In one embodiment of the present invention, the third latency may be the latency between the gateway and the server or the latency between the gateway and the network-side data terminal. The third latency can be obtained through QoS measurement or is a configured value, including a maximum value. The latency between the gateway and the server may include the maximum latency between the gateway and the server. The latency between the gateway and the network-side data terminal may include the maximum latency between the gateway and the network-side data terminal.

[0192] In optional embodiments of this application, the concepts of delay information and delay can be used interchangeably. Delay information can be used to represent delay. In optional embodiments of this application, delay or delay information may include at least one of the following: delay overhead, delay budget. The delay budget (delay buffer) refers to the delay that cannot exceed the delay budget requirement.

[0193] In optional embodiments of this application, the delay may be transmission delay and / or computation delay. Therefore, the delay or delay information may include at least one of the following: transmission delay overhead, transmission delay budget, computation delay overhead, and computation delay budget.

In another embodiment, the terminal-side data terminal can be a data source, and the network-side data terminal can be a data destination; alternatively, the terminal-side data terminal can be a data destination, and the network-side data terminal can be a data source. In services, data is often bidirectional, meaning the data terminal is simultaneously both a data source and a data destination.

[0195] In one optional embodiment of this application, the terminal-side data terminal includes a data terminal connected to the terminal. The terminal-side data terminal can be located inside or outside the terminal. The network-side data terminal includes a data terminal connected to a communication network.

[0235] Optionally, the service and / or data description information is the service and / or data description information related to the latency information. The UE-internal latency information is the UE-internal latency information related to the service and / or data description information. Different services and / or data may correspond to different UE-internal latencies.

[0236] The following describes the service quality assurance method according to the embodiments of this application.

[0237] Please refer to Figure 3 This application provides a method for ensuring quality of service, applied to a first communication device; the first communication device includes, but is not limited to, a UE, an AMF, and an AF; the method includes:

[0238] Step 31: Send the first message.

[0239] In this embodiment, the first information may include at least one of the following:

[0240] First request information; the first request information is used to request service-level QoS guarantee for the first object;

[0241] Description information of the first object;

[0242] Service-level QoS information;

[0243] The first latency information includes one of the following: intra-terminal latency information, and inter-terminal latency information between the terminal-side data terminal and the terminal.

[0244] The fourth latency information includes one of the following: latency information within the server, and latency information within the network-side data terminal.

[0245] The first object includes at least one of the following: a terminal, a first service, a first information, a first data, a first data channel, and a first computing task.

[0246] The description information of the first object includes at least one of the following: description information of the terminal, description information of the first service, description information of the first information, description information of the first data, description information of the first data channel, and description information of the first computing task.

[0247] In one implementation, computing power requirements can be converted into latency requirements within the server.

[0248] In one implementation, the terminal can send both first latency information and fourth latency information. For example, in a scenario where the terminal needs to perform split computation, i.e., some computation occurs on the terminal and the remaining computation occurs on the server, the terminal can simultaneously provide first latency information (such as the terminal's internal computation latency) and fourth latency information (the server's computation latency).

[0249] In another implementation, the terminal can send the fourth latency information. For example, in one scenario, the terminal offloads all computation to a server. In this case, the fourth latency information can be the computation latency within the server.

[0250] In another implementation, the first delay information and the fourth delay information can be sent by different first communication devices. For example, the first delay information can be sent by the terminal, and the fourth delay information can be sent by a proxy (such as AF) on the server side.

[0251] In another implementation, the first communication device provides first latency information. Given a fixed service-level latency, the second communication device can derive fourth latency information from the first latency information.

[0252] In another implementation, the first communication device provides fourth latency information. Given a fixed service-level latency, the second communication device can deduce the first latency information from the fourth latency information.

[0253] Optionally, the above service-level QoS information includes: service-level latency. This service-level latency is also referred to as service-level delay.

[0254] In one optional embodiment of this application, the aforementioned service-level QoS or service-level QoS information includes the end-to-end latency between the data source and the data destination.

[0255] Optionally, the terminal latency information includes at least one of the following: terminal computation latency information, and terminal transmission latency information.

[0256] 1) Further, the in-terminal computing latency may include the latency (such as the required duration) of data, services and / or computing tasks being computed within the terminal.

[0257] In one embodiment, the in-terminal computing latency information includes at least one of the following: in-terminal computing latency overhead, and in-terminal computing latency budget.

[0258] For example, in-terminal computing latency includes the latency of business or computing tasks within the terminal. In distributed computing, for instance, a terminal can handle some of the computation, while the rest occurs outside the terminal (e.g., on a server or another terminal). In this case, in-terminal computing latency is part of the end-to-end latency of the business. Alternatively, in-terminal computing latency can be zero. It's easy to understand that the terminal can offload all computation outside the terminal, as in cloud computing. Furthermore, the in-terminal computing latency can vary depending on the business, data, and / or computing task.

[0259] 2) Furthermore, the intra-terminal transmission delay information may include the time required for data to be forwarded within the terminal. For example, the intra-terminal transmission delay information includes the delay from the client on the terminal to the time before the data is sent from the terminal to the communication network.

[0260] Optionally, the server latency information includes at least one of the following: server computation latency, server transmission latency.

[0261] Optionally, the latency information between the terminal-side data terminal and the terminal includes at least one of the following: latency information calculated between the terminal-side data terminal and the terminal, latency information transmitted between the terminal-side data terminal and the terminal, latency information within the terminal, and latency information within the terminal-side data terminal.

[0262] Furthermore, the computational latency information between the terminal-side data terminal and the terminal may include the computational latency of data, services, and / or computational tasks between the terminal-side data terminal and the terminal.

[0263] Furthermore, the transmission delay information between the terminal-side data terminal and the terminal can include the time required for data to be forwarded between the terminal-side data terminal and the terminal.

[0264] Optionally, the latency information within the network-side data terminal includes at least one of the following: computation latency information within the network-side data terminal, and transmission latency information within the network-side data terminal;

[0265] Optionally, the latency information within the terminal-side data terminal includes at least one of the following: computation latency information within the terminal-side data terminal, and transmission latency information within the terminal-side data terminal.

[0266] It should be noted that the terminal-side data terminal can be located inside or outside the terminal. The data terminal can be the source or destination of the data.

[0267] In this embodiment of the application, the first communication device (such as a terminal) may also receive a first response and / or service level QoS guarantee activation information, and send information and / or data of the first object or target object according to the first response and / or service level QoS guarantee activation information.

[0268] The first response indicates that the first request was successfully responded to.

[0269] The service-level QoS guarantee activation information includes at least one of the following: indication information for activating service-level QoS guarantee, and description information of the target object for service-level QoS guarantee. The description information of the target object includes: description information of the target service.

[0270] It is easy to understand that, through this embodiment, when the latency budget at the service level is determined, if some latency overhead changes in the first, second, third, and / or fourth latency, the requirements of the service-level latency budget can be guaranteed by adjusting the remaining latency budget.

[0271] Please refer to Figure 4 This application also provides a quality of service assurance method, applied to a second communication device; the second communication device includes, but is not limited to, a CN network element (such as an SMF); the method includes:

[0304] Service-level QoS guarantees are not allowed and / or not required.

[0305] Description information of objects that allow and / or require service-level QoS guarantees.

[0306] Description information of objects that are not allowed and / or do not require service-level QoS guarantees.

[0307] In one implementation, the subscription information related to the service-level QoS guarantee is the subscription information of the terminal, the service provider, and / or a third party for the service-level QoS guarantee operation.

[0308] In one embodiment, the second communication device can obtain first information from the first communication device, and further, it can obtain different contents of the first information from different first communication devices.

[0309] In one implementation, the service-level QoS information includes the service-level QoS information of the second object.

[0310] In one implementation, the second object may be the same as or different from the first object.

[0311] In another implementation, the second object is the services in the first object that are permitted by the subscription information related to service-level QoS guarantees. For example, only some services in a portion of the first object are permitted by the subscription information related to service-level QoS guarantees. It is easy to understand that in this case, the second object is a subset of the first object.

[0312] In this embodiment of the application, step 42 may include: performing a first operation when a first condition is met. The first condition includes at least one of the following:

Further, the service-level latency change includes at least one of the following: service-level latency overhead is close to or exceeds the service-level latency budget, the service-level latency budget changes, and the service-level latency overhead increases.

[0324] The aforementioned service-level latency consists of a first latency, a second latency, a third latency, and a fourth latency. In one embodiment, when the first latency and / or the third latency changes, to avoid situations where service-level latency guarantees cannot be met, the service-level latency overhead can be made to meet the service-level latency budget by adjusting the second latency budget and / or the fourth latency budget. In another embodiment, when the fourth latency changes, the second latency budget can be adjusted. In yet another embodiment, when the second latency changes, the fourth latency budget can be adjusted.

[0337] Optionally, the second communication device may also send a first response and / or service-level QoS guarantee activation information to the first communication device.

[0377] The third latency information includes one of the following: latency between the gateway and the server, latency between the communication network and the server, latency between the gateway and the network-side data terminal, and latency between the communication network and the network-side data terminal.

[0378] Optionally, the QoS guarantee requirements in the server include: server-wide latency.

[0397] It is easy to understand that, through this embodiment, when the latency budget at the service level is determined, if some latency changes between the first latency, the second latency, the third latency, and / or the fourth latency, the requirements of the service-level latency budget can be guaranteed by adjusting the remaining latency.

[0398] Please refer to Figure 6 This application also provides a quality of service assurance method applied to a fourth communication device; the fourth communication device includes: a CN network element (such as a UDM); the method includes:

[0399] Step 61: Obtain a third request, wherein the third request is used to request subscription information related to service-level QoS assurance.

[0400] Optionally, this third request can be a registration / signing data acquisition / subscription request.

[0401] Optionally, the subscription information related to the service-level QoS guarantee includes at least one of the following:

[0402] Allow and / or require service-level QoS guarantees.

[0404] Description information of objects that allow and / or require service-level QoS guarantees.

[0405] Description information of objects that are not allowed and / or do not require service-level QoS guarantees.

[0406] In one implementation, the subscription information related to the service-level QoS guarantee is the subscription information of the terminal, the service provider, and / or a third party for the service-level QoS guarantee operation.

[0407] Step 62: Based on the third request, send the subscription information related to service-level QoS guarantees.

[0408] Optionally, the subscription information related to the service-level QoS guarantee may further include: descriptive information of the objects allowed to be guaranteed by the service-level QoS guarantee. The objects include at least one of the following: terminal, service, information, data, and data channel.

[0409] It is easy to understand that through this embodiment, one can request and obtain subscription information related to service-level QoS assurance, thereby meeting the service-level QoS assurance requirements.

[0410] The methods provided in the embodiments of this application are described below in conjunction with specific application scenarios.

[0411] In this application scenario one, such as Figure 7 As shown, the specific service quality assurance process may include:

[0412] Step 71: The UE sends an uplink NAS message to the AMF via the RAN. This uplink NAS message may include a PDU session establishment request. The PDU session request includes first information, such as... Figure 3 As described in the embodiments.

[0413] Step 72: The AMF sends the PDU session creation SM context information to the SMF, which includes the first information.

[0414] It should be noted that the content of the first information in steps 71 and 72 can be found in the above embodiments, and will not be repeated here.

[0415] Step 73: The SMF obtains relevant information for the first operation, which, for example, includes at least one of the following: first information, second latency information, and subscription information for the UE's service-level QoS guarantee. Based on this information, the SMF executes the first operation. Furthermore, the SMF sends a registration / subscription data acquisition / subscription request to the UDM to request subscription information for the service-level QoS guarantee from the UDM.

[0416] The second latency information, the UE's service-level QoS guarantee subscription information, and the first operation involved in step 73 can be found in the above embodiments and will not be repeated here.

[0417] Step 74: The SMF sends a policy establishment request to the PCF, the policy establishment request including the second information, and obtains a policy establishment response from the PCF. This policy establishment response may include service-level QoS guarantee-related policy information.

[0418] Among these, PCF can obtain subscription information for service-level QoS guarantees from UDM.

[0419] Specifically, the PCF can execute the second operation based on relevant information of the second operation, including second information and / or second delay information. This second operation can be found in the embodiments described above, and will not be repeated here.

[0420] Among them, SMF can perform a third operation based on the service-level QoS guarantee policy information.

[0421] The third operation includes at least one of the following:

[0422] Determine the second delay information, which includes one of the following: delay between the terminal and the gateway, and transmission delay within the communication network;

[0423] The fourth latency information is determined, which includes one of the following: latency information within the server, and latency information within the network-side data terminal;

[0424] Determine the QoS guarantee requirement information in the server, wherein the QoS guarantee requirement information in the server includes fourth latency information;

[0425] Determine the relevant policy information for service-level QoS guarantees used for user plane network elements.

[0426] In one implementation, the PCF first determines the first latency, and the SMF, based on the end-to-end service level latency, the first latency, and the second latency, can determine the latency budget within the server.

[0427] In another implementation, the SMF first determines the server latency and sends it to the PCF, which then determines the first latency. The SMF can determine the computing resources and server latency required for the first service based on the computing power sensing network element.

[0428] Step 75: The SMF sends service-level QoS guarantee policy information to the UPF through the N4 session establishment request and obtains the confirmation information returned by the UPF.

[0429] Steps 76, 77, and 78: The SMF sends a first response and / or service-level QoS assurance activation information to the UE via the AMF, RAN, etc. The first response indicates that the first request was successfully responded to.

[0430] Subsequently, the UE sends the target service data based on the first response and / or service-level QoS assurance activation information. After receiving the target service data sent by the UE, the UPF executes service-level QoS assurance related policies (such as QoS monitoring).

[0431] Understandable Figure 7 The other steps are all existing session establishment and modification processes, which will not be elaborated here.

[0432] In this second application scenario, such as Figure 8 As shown, the specific service quality assurance process may include:

[0433] Step 81: The AF sends an AF session establishment request to the PCF via the NEF. This AF session establishment request includes first information, such as... Figure 3 As described in the embodiments.

[0434] It should be noted that the content of the first information in this step 81 can be found in the above embodiments, and will not be repeated here.

[0435] Step 82: The PCF obtains relevant information for the second operation, which, for example, includes at least one of the following: first information, second latency information, and subscription information for the UE's service-level QoS guarantee. Based on this information, the PCF performs the second operation. Furthermore, the PCF sends a registration / subscription data acquisition / subscription request to the UDM to request subscription information for the service-level QoS guarantee from the UDM.

[0436] The second latency information, the UE's service-level QoS guarantee subscription information, and the second operation involved in step 82 can be found in the above embodiments and will not be repeated here.

[0437] Optionally, when it is determined that service-level QoS guarantee policy information is generated, proceed to step 83.

[0438] Step 83: The PCF sends service-level QoS guarantee policy information to the SMF through a policy update request and obtains the policy update response returned by the SMF.

[0439] Among them, SMF generates service-level QoS guarantee policy information for use on UPF based on service-level QoS guarantee policy information.

[0440] Step 84: The SMF sends service-level QoS guarantee policy information to the UPF through the N4 session establishment request and obtains the confirmation information returned by the UPF.

[0441] Steps 85, 86, and 87: The SMF sends a first response and / or service-level QoS assurance activation information to the UE via the AMF, RAN, etc. The first response indicates that the first request was successfully responded to.

[0442] Subsequently, the UE sends the target service data based on the first response and / or service-level QoS guarantee activation information. The UPF, upon receiving the target service data from the UE, performs privacy protection before forwarding it.

[0443] Understandable Figure 8 The other steps are all existing session establishment and modification processes, which will not be elaborated here.
