[0037] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

The communication system 100 may include a network device 110, which may be a device that communicates with a terminal 120 (or referred to as a communication terminal, terminal).

[0040] The communication system 100 also includes at least one terminal 120 located within the coverage area of ​​the network device 110. As used herein, "terminal" includes, but is not limited to, a connection via a wired line, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection; and / or another data connection / network; and / or via a wireless interface, such as for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter; and / or another terminal configured to receive / send communication signals; and / or an Internet of Things (IoT) device. A terminal configured to communicate via a wireless interface may be referred to as a "wireless communication terminal," "wireless terminal," or "mobile terminal." Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; Personal Communications System (PCS) terminals that may combine cellular radiotelephones with data processing, fax, and data communications capabilities; PDAs that may include radiotelephones, pagers, Internet / Intranet access, web browsers, organizers, calendars, and / or Global Positioning System (GPS) receivers; and conventional laptop and / or palmtop receivers or other electronic devices that include radiotelephone transceivers. A terminal may be referred to as an access terminal, user equipment (UE), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device.

[0041] Optionally, the terminals 120 may perform device-to-device (D2D) communication with each other.

[0042] Optionally, the 5G communication system or 5G network may also be referred to as a New Radio (NR) system or NR network.

[0043] Figure 1 One network device and two terminals are shown as an example. Optionally, the communication system 100 may include multiple network devices and each network device may include another number of terminals within its coverage area. This embodiment of the present application does not limit this.

[0044] Optionally, the communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present application.

[0045] It should be understood that the device with communication function in the network / system in the embodiment of the present application can be called a communication device. Figure 1 Taking the communication system 100 shown as an example, the communication equipment may include a network device 110 and a terminal 120 with communication functions. The network device 110 and the terminal 120 may be the specific devices described above and will not be repeated here; the communication equipment may also include other devices in the communication system 100, such as a network controller, a mobile management entity and other network entities, which is not limited in the embodiments of the present application.

[0046] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0047] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

[0048] As networks become increasingly artificially intelligent, Artificial Intelligence (AI) and Machine Learning (ML) will be incorporated into mobile networks. Therefore, a mechanism is needed to enable negotiation between terminals and the network regarding big data analysis models (also called network models, or simply models for short) to ensure that communication networks can support big data analysis.

[0049] Big data analysis models include Deep Neural Network (DNN), Recurrent Neural Network (RNN), Convolutional Neural Network (CNN), and Multilayer Perception (MPL). The most widely used model is the DNN. DNN models are classified by their layers, and the neural network layers within a DNN model can be divided into three categories: input layer, hidden layer, and output layer. Generally speaking, the first layer of a DNN model is the input layer, the last layer is the output layer, and all layers in between are hidden layers.

[0050] In order to improve the effectiveness of big data analysis and user experience, it is possible to consider adopting a multi-level AI / ML approach, that is, dividing the work of big data analysis between the network side and the terminal.

[0051] A typical division of labor is Figure 2-1 As shown, the terminal partially processes the data to form intermediate data, and then sends the intermediate data to the service server via the mobile network for further processing. This helps share the workload and protect the terminal's privacy.

[0052] For scenarios with multiple terminals, there are many options for big data analysis, such as Figure 2-2 As shown in the figure, (a) is a centralized scenario, where all terminals report the required data, and all big data analysis is performed on the network side. (b) is a fully distributed scenario, where different terminals analyze the collected data locally. (c) is a hybrid scenario, where terminals perform a portion of the analysis locally and then send the results to the network side for further computation and analysis. Furthermore, in (b) and (c), data interaction between terminals can be introduced to complete big data analysis or result sharing.

[0053] For example, if Figure 2-3 As shown in Figure 1, big data analysis can be distributed across the terminal, edge server, and cloud server, or it can be performed on only one or two of these three. Therefore, the terminal may allocate different network models and computing workloads as needed, and complete the calculation within the required time and successfully send it to the network side.

[0054] As can be seen from the above description, communication is required between the terminal and the network to ensure data exchange. Here, communication quality is very important. If the terminal cannot send processed data to the business server in a timely manner, the network side will need to wait, causing the business server's computing resources to be idle and unable to achieve optimal big data analysis efficiency.

[0055] For a multi-layer network model, if the workload is assigned to the terminal in different splitting methods, the computing time and the amount of data generated by the terminal in each splitting method will be different. Figure 2-4 As shown in Figure 1, it reflects the computing time and data volume generated by the terminal at each layer for a network model. Figure 2-4 You can see the time it takes for the terminal to process data (called computation time) and the amount of output data generated after the terminal processes the data. If the first-layer workload is performed by the terminal, the time it takes to process the data is the computation time represented by the light-colored bar to the left of split point 1, and the amount of output data generated is the amount of data indicated by the arrow at split point 1. The subsequent output data can then be transmitted to the business server on the network side for further processing. The same applies to other split points.

[0056] from Figure 2-4 It can be seen that different splitting methods of the network model have different requirements for the processing power and transmission capacity of the terminal. In order to ensure the transmission of data, mobile networks generally use the QoS mechanism. In the QoS mechanism, a set of QoS parameters is used for the data transmission of one or more QoS flows (QoS flow) or bearers. Here, the bearer specifically refers to the data radio bearer (Data Resource Bearer, DRB), and one or more QoS flows can be mapped to a DRB for transmission. For a QoS flow, corresponding to a set of QoS parameters, the base station on the air interface will establish a DRB based on the QoS parameters and bind the QoS flow to a specific DRB. A set of QoS parameters can specifically include the following parameters:

[0057] -5QI: used to retrieve the QoS parameters of a specific service.

[0058] -Rate: GBR and MBR, where GBR is the guaranteed rate and MBR is the maximum achievable rate.

[0059] -Packet Loss Rate: also known as PER.

[0060] - Transmission delay: Transmission delay = AN-PDB + CN-PDB, where AN-PDB represents the transmission delay between the terminal and the base station on the air interface, and CN-PDB represents the transmission delay between the base station and the user plane network element of the core network.

[0061] Averaging window: This window is used to examine whether key QoS parameters such as rate and packet loss rate are guaranteed. Specifically, the average values ​​of QoS parameters (such as rate and packet loss rate) within the window are examined to see if they meet the specified values.

[0062] - Allocation Retension Priority (ARP): represents the preemption priority or forced priority of the QoS flow or bearer corresponding to the QoS parameter, which can be used when network resources are tight (such as air interface resource congestion).

[0063] -Priority: represents the priority of the QoS flow or bearer.

[0064] Current QoS mechanisms only consider data transmission guarantees. As the above analysis demonstrates, big data analysis requires not only data transmission guarantees but also data processing guarantees, such as the time required for data processing. Furthermore, some distributed or hybrid big data analysis scenarios require a certain number of terminals to complete the analysis. Because the channel quality of different terminals often varies over time, the network can guarantee that only a certain percentage or number of terminals can perform big data analysis, without specifying which terminals must perform the analysis.

[0065] To this end, the following technical solutions of the embodiments of the present application are proposed. It should be noted that the "data" in the embodiments of the present application can be network model data or ordinary data. The "computation time" in the embodiments of the present application can also be referred to as "processing time". The solutions of the embodiments of the present application can be applied not only to AI computing, but also to scenarios such as ordinary data computing or edge computing.

[0066] Figure 3 A flow chart of a data transmission method provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the data transmission method includes the following steps:

[0067] Step 301: Each of at least one node allocates corresponding computing resources and / or transmission resources according to QoS parameters, wherein the at least one node includes at least one of the following: a terminal, an access network element, a core network user plane element, and a service server.

[0068] In the embodiments of the present application, the computing nodes and / or transmission nodes involved in data analysis include at least one of the following: a terminal, an access network element, a core network user plane element, and a service server. The terminal is a computing node and a transmission node; the access network element is a transmission node; the core network user plane element is a transmission node; and the service server is a computing node and a transmission node.

[0069] Further, optionally, the access network element may be a base station.

[0070] Furthermore, optionally, the service server may be a network model server (i.e., an AI server). However, the service server may also be a common service server, an edge server, or a network data analytics function (NWDAF) in 3GPP.

[0071] The technical solutions of the embodiments of the present application can be applied to, but are not limited to, 5G networks and 4G networks. Depending on the network type, the implementation of the core network user plane network element and the access network network element may vary. Taking a 5G network as an example, the core network user plane network element may be a user plane function (UPF) network element, and the access network network element may be a gNB.

[0072] In the embodiments of the present application, the current QoS parameters are expanded. Specifically, in addition to existing data transmission-related parameters, the QoS parameters also include parameters related to data calculation. The existing data transmission-related parameters can refer to the aforementioned description of QoS parameters, for example, including the following parameters: 5QI, packet loss rate, averaging window, ARP, Priority, etc.

[0073] For scenarios with high data computing and data transmission performance requirements, QoS parameters need to consider both data transmission and data computing. To this end, the QoS parameters of the embodiment of the present application also need to include at least one of the following parameters related to data computing:

[0074] A first parameter, wherein the first parameter is used to determine the total delay of the data;

[0075] a second parameter, the second parameter being used to determine a total rate of the data;

[0076] A third parameter is used to determine at least one of a time, a time period, and a cycle when data arrives at each node of the at least one node.

[0077] The implementation of the first parameter, the second parameter, and the third parameter is described below.

[0078] ● A first parameter, which is used to determine the total delay of the data.

[0079] Here, the total delay includes the additional delay and at least one of the following:

[0080] A first transmission delay, where the first transmission delay refers to the transmission delay between the user module of the terminal and the access network element;

[0081] The second transmission delay refers to the transmission delay between the access network element and the core network user plane element.

[0082] For example: total delay = AN_PDB + CN_PDB + additional_PDB, where AN_PDB represents the first transmission delay (i.e., the transmission delay between the user module of the terminal and the access network network element), CN_PDB represents the second transmission delay (i.e., the transmission delay between the access network network element and the core network user plane network element), and additional_PDB represents the additional delay.

[0083] For example: total delay = AN_PDB + additional_PDB, where AN_PDB represents the first transmission delay (ie, the transmission delay between the user module of the terminal and the access network element), and additional_PDB represents the additional delay.

[0084] For example: total delay = CN_PDB + additional_PDB, where CN_PDB represents the second transmission delay (i.e., the transmission delay between the access network element and the core network user plane element), and additional_PDB represents the additional delay.

[0085] In the above solution, optionally, at least one of AN-PDB and CN-PDB may be defined according to a value.

[0086] In an optional manner, the additional delay in the above solution includes at least one of the following:

[0087] a first calculation time, where the first calculation time refers to the calculation time of a service processing module of the terminal;

[0088] A first transmission time, where the first transmission time refers to the transmission time between the service processing module and the user module of the terminal;

[0089] A second calculation time, wherein the second calculation time refers to the calculation time of the service server;

[0090] The second transmission time refers to the transmission time between the service server and the user plane network element of the core network.

[0091] In an optional embodiment, the first calculation time and / or the first transmission time is the terminal-side service processing time; the second calculation time and / or the second transmission time is the network-side service processing time. For example: terminal-side service processing time = first calculation time + first transmission time. Network-side service processing time = second calculation time + second transmission time.

[0092] Reference Figure 4 , total delay = terminal side service processing time + AN_PDB + CN_PDB + network side service processing time.

[0093] It should be noted that the various parameters in the above scheme can be parameters for the uplink or for the downlink. For example, for the uplink, the first transmission delay is specifically the first uplink transmission delay, the second transmission delay is specifically the second uplink transmission delay, the first transmission time is specifically the first uplink transmission time, and the second transmission time is specifically the second uplink transmission time. For another example, for the downlink, the first transmission delay is specifically the first downlink transmission delay, the second transmission delay is specifically the second downlink transmission delay, the first transmission time is specifically the first downlink transmission time, and the second transmission time is specifically the second downlink transmission time.

[0094] • A second parameter, which is used to determine the overall rate of the data.

[0095] Here, the total rate is the minimum value of the total calculation rate and the total transmission rate.

[0096] For example: total rate = min(total computing rate, total transmission rate).

[0097] In an optional manner, the total computation rate in the above scheme is the minimum of the following computation rates:

[0098] a first calculation rate, where the first calculation rate refers to a calculation rate of a service processing module of the terminal;

[0099] The second calculation rate refers to the calculation rate of the service server on the network side.

[0100] For example: total calculation rate = min(first calculation rate, second calculation rate).

[0101] In an optional manner, the total transmission rate in the above scheme is the minimum of the following transmission rates:

[0102] A first transmission rate, where the first transmission rate refers to a transmission rate between a service processing module and a user module of a terminal;

[0103] A second transmission rate, where the second transmission rate refers to a transmission rate between a user module of the terminal and a network element of the access network;

[0104] A third transmission rate, wherein the third transmission rate refers to the transmission rate between the access network element and the core network user plane network element;

[0105] The fourth transmission rate refers to the transmission rate between the core network user plane network element and the service server.

[0106] For example: total transmission rate = min(first transmission rate, second transmission rate, third transmission rate, fourth transmission rate).

[0107] Here, optionally, the second transmission rate may be a DRB transmission rate between a user module of the terminal and an access network element.

[0108] Here, optionally, the third transmission rate may be a transmission rate of a CN tunnel between an access network element and a core network user plane element.

[0109] Through the above description, it can be equivalently concluded that: total rate = min(first calculation rate, second calculation rate, first transmission rate, second transmission rate, third transmission rate, fourth transmission rate).

[0110] Reference Figure 5 As an example of the total delay, for a specific network model, part of the network model is allocated to the terminal for calculation, and the other part is allocated to the service server for calculation. The total time from the leftmost input to the rightmost output of the entire network model can be guaranteed by the QoS parameter (i.e., total delay). Regarding the total rate, the total rate is the minimum of the terminal calculation rate (i.e., the first calculation rate), the service server calculation rate (i.e., the second calculation rate), and the total transmission rate.

[0111] It should be noted that the various parameters in the above scheme can be parameters for uplink or parameters for downlink. For example: for uplink, the first transmission rate is specifically the first uplink transmission rate, the second transmission rate is specifically the second uplink transmission rate, the third transmission rate is specifically the third uplink transmission rate, the fourth transmission rate is specifically the fourth uplink transmission rate, the terminal calculation rate (i.e., the first calculation rate) is the rate of intermediate state data output by the terminal, and the service server calculation rate (i.e., the second calculation rate) is the data rate that the service server can receive and process. For another example: for downlink, the first transmission rate is specifically the first downlink transmission rate, the second transmission rate is specifically the second downlink transmission rate, the third transmission rate is specifically the third downlink transmission rate, the fourth transmission rate is specifically the fourth downlink transmission rate, the service server calculation rate (i.e., the second calculation rate) is the rate of intermediate state data output by the service server, and the terminal calculation rate (i.e., the first calculation rate) is the data rate that the terminal can receive and process.

[0112] A third parameter is used to determine at least one of a time, a time period, and a cycle at which data arrives at each of the at least one node.

[0113] Optionally, the third parameter may be referred to as a burst arrival time (BRT), which is used to inform each node of the time and / or time period and / or cycle of data arrival, so that each node can reserve sufficient transmission resources for data transmission and / or sufficient computing resources for data computation. Furthermore, in an optional embodiment, to better utilize the burst arrival time, one or more of the above nodes may synchronize their own clocks.

[0114] Reference Figure 4 The core network control plane network element sends the burst arrival time to the terminal, the access network network element, the core network user plane network element and the service server respectively. Optionally, the core network control plane network element may be a session management function network element (SMF).

[0115] It should be noted that the various parameters in the above solution can be parameters for uplink or downlink. For example, for uplink, the burst arrival time is specifically the uplink burst arrival time. For another example, for downlink, the burst arrival time is specifically the downlink burst arrival time.

[0116] On the basis of the above technical solution, the technical solution of the embodiment of the present application further introduces a group QoS mechanism. To this end, the following new parameters are introduced on the basis of the above QoS parameters:

[0117] a fourth parameter, the fourth parameter being used to determine an identifier of the group;

[0118] a fifth parameter, the fifth parameter being used to determine the number of terminals included in the group;

[0119] a sixth parameter, the sixth parameter being used to determine the number of valid terminals in the group or the proportion of valid terminals in the group;

[0120] a seventh parameter, wherein the seventh parameter is used to determine an area range of the group;

[0121] The group refers to a group of terminals that are applicable to the QoS parameters.

[0122] In an optional manner, the seventh parameter includes at least one of the following: geographic coordinates, a cell identifier, a base station identifier, a tracking area (TA) identifier, and a public land mobile network (PLMN) identifier.

[0123] It should be noted that the above parameters may be part of the QoS parameters or may not be part of the QoS parameters. In other words, the QoS parameters of the embodiment of the present application may include the above parameters or be associated with the above parameters.

[0124] In an optional manner, the above parameters may also have other names, for example: the fourth parameter is called the group identifier, where multiple terminals that apply a set of QoS parameters correspond to the same group identifier. The fifth parameter is called the number of groups. The sixth parameter is called the number of valid terminals or the valid percentage, which is used to determine the number of valid terminals or the proportion of valid terminals that must be guaranteed in the group at a specific time point, time period, or cycle. The seventh parameter is called the location range. It should be noted that a valid terminal refers to a terminal in the group that can perform data calculations or a terminal that has established a connection with the network side.

[0125] It should be noted that the above-mentioned group QoS mechanism solution can also be implemented individually. Specifically, a group includes multiple first nodes. The connection between some or all of the first nodes in the group and the second node meets the QoS requirement specified by at least one of the following parameters: GBR, MBR, PER, PDB, total delay between the first node and the second node, and total transmission rate between the first node and the second node.

[0126] Here, the total delay can refer to the description related to the total delay in the aforementioned embodiments of the present application.

[0127] Here, the total transmission rate can refer to the description related to the total transmission rate in the previous embodiments of the present application.

[0128] Here, the group includes terminals and / or network side nodes; the second node is a terminal or a network side node. Further, optionally, the network side node includes at least one of the following: an access network element, a core network user plane element, and a service server.

[0129] For example, the group includes multiple terminals, and the second node is an access network element. The above parameters can ensure QoS between the multiple terminals and the access network element.

[0130] For example, the group includes multiple first terminals, and the second node is a second terminal. The above parameters can ensure the QoS of direct communication between a group of terminals and another terminal.

[0131] For example, the group includes multiple edge servers, and the second node is a central server. The above parameters can ensure QoS between a group of edge servers and another central server.

[0132] In order to ensure that connections between some or all first nodes and second nodes in a group meet QoS requirements specified by the above parameters, some or all first nodes in the group receive QoS parameters, where the QoS parameters include or are associated with at least one of the following:

[0133] a fourth parameter, the fourth parameter being used to determine an identifier of the group;

[0134] a fifth parameter, the fifth parameter being used to determine the number of terminals included in the group;

[0135] a sixth parameter, the sixth parameter being used to determine the number of valid terminals in the group or the proportion of valid terminals in the group;

[0136] a seventh parameter, wherein the seventh parameter is used to determine an area range of the group;

[0137] The group refers to a group of terminals that are applicable to the QoS parameters.

[0138] In an optional manner, some or all of the first nodes in the group are determined by at least one of the following parameters: the area range of the group, the number of valid terminals in the group, the proportion of valid terminals in the group, and the duration of maintaining a certain number of valid terminals in the group.

[0139] For example, all or some of the terminals in the group receive QoS parameters, which include or are associated with at least one of the following parameters: a fourth parameter, a fifth parameter, a sixth parameter, and a seventh parameter. All or some of the terminals in the group ensure that their connections with the network meet the requirements specified by the parameters.

[0140] It should be noted that the above parameters may be part of the QoS parameters or may not be part of the QoS parameters. In other words, the QoS parameters of the embodiment of the present application may include the above parameters or be associated with the above parameters.

[0141] In an optional manner, the QoS parameters received by different nodes in the part or all of the first nodes may be the same or different. For example, different nodes in the part or all of the first nodes may receive QoS parameter content related to themselves. Alternatively, all nodes in the part or all of the first nodes receive the same QoS parameter content (which includes QoS parameter content related to all nodes).

[0142] In the above solution, the QoS parameters are sent by a core network control plane network element. Further, optionally, the core network control plane network element may be an SMF.

[0143] For example: refer to Figure 6 The coverage area of ​​multiple base stations is the group area. Within this area, a group of 16 terminals is defined (all 16 terminals correspond to the same group identifier). 50% or more of the terminals in this group must meet QoS requirements. Within each period of T, 8 terminals (or 50% of the terminals) must meet the specified set of QoS parameters. The number of active terminals cannot change during this period. When the period expires, QoS can be guaranteed for other terminals in the next period, but the number of active terminals must still be 50% or more of the total number of terminals in the group. Here, the duration for maintaining a certain number of active terminals in the group is T.

[0144] It should be noted that the valid terminal can be changed at a specified time point or time period, otherwise the QoS of the currently determined valid terminal must be guaranteed.

[0145] The group QoS mechanism can be used in federated computing scenarios, where a service server needs to obtain computation results from a certain number of terminals at a specific time or time period, without being limited to specific terminals. Furthermore, the group QoS mechanism helps protect terminal privacy, as the service server is unaware of which terminals have guaranteed QoS parameters.

[0146] On the basis of the above technical solutions, the technical solutions of the embodiments of the present application further include a solution for configuring QoS parameters, which is described below.

[0147] The at least one node receives the QoS parameter and / or the parameter associated with the QoS parameter sent by the network-side network element.

[0148] Further, optionally, all or part of the at least one node sends capability information to a network side network element, and the capability information is used by the network side network element to determine the QoS parameter and / or parameters associated with the QoS parameter.

[0149] Here, the network side network element is a core network control plane network element. Further, optionally, the core network control plane network element may be an SMF.

[0150] In the above solution, the capability information includes at least one of the following: capability information of the terminal and capability information of the service server.

[0151] In an optional manner, the terminal capability information is reported by the terminal to the network side network element via a non-access stratum (NAS) message. Optionally, the NAS message may be a registration request message, a service request message, a session establishment request message, or a session modification request message.

[0152] Here, the capability information of the terminal includes at least one of the following:

[0153] The computing time supported by the service processing module of the terminal (for example, the maximum computing time supported or the maximum computing time allowed);

[0154] A computing rate supported by the service processing module of the terminal (for example, a maximum supported computing rate or a maximum allowed computing rate);

[0155] The transmission time between the service processing module and the user module supported by the terminal (eg, the maximum transmission time supported, or the maximum transmission time allowed).

[0156] In an optional manner, the capability information of the service server is reported by the service server or the terminal to the network-side network element.

[0157] Here, the capability information of the service server includes at least one of the following:

[0158] The computing time supported by the service server (e.g., the maximum supported computing time or the maximum allowed computing time);

[0159] The computing rate supported by the service server (e.g., the maximum computing rate supported, or the maximum computing rate allowed);

[0160] The transmission time between the service server and the user plane network element of the core network supported by the service server (for example, the maximum transmission time supported, or the maximum transmission time allowed)

[0161] The network side network elements uniformly collect the above capability information, and determine and issue QoS parameters based on the above capability information.

[0162] Reference Figure 7 ,The process of capability reporting and QoS parameter delivery includes the following steps:

[0163] 1: The terminal reports its capability information to the core network control plane network element. Optionally, the terminal may also report the capability information of the service server to the core network control plane network element.

[0164] 2: The core network control plane network element sends QoS parameters to the core network user plane network element.

[0165] 3: The core network control plane network element sends QoS parameters to the service server.

[0166] 4: The core network control plane NE sends QoS parameters to the access network NE.

[0167] 5: The core network control plane network element sends QoS parameters to the terminal.

[0168] It should be noted that the execution order of the above steps 2 to 5 is not limited. One or more of the terminal, access network element, core network user plane element, and service server allocates corresponding resources (such as computing resources, transmission resources, etc.) according to the QoS parameters to ensure the QoS parameters.

[0169] It should be noted that, in an optional method, the above steps 4 and 5 can be combined into one message, that is, the message sent by the core network control plane network element to the access network network element includes a NAS message, and the NAS message is transparently transmitted to the terminal through the access network network element, wherein the NAS message carries a container carrying the QoS parameters.

[0170] The technical solutions of the embodiments of this application expand the current QoS mechanism to incorporate computing power to meet the needs of mobile networks that support big data analysis. Furthermore, a group QoS mechanism is introduced, which is suitable for specific application scenarios or for achieving privacy protection. Furthermore, the technical solutions of the embodiments of this application fully utilize existing processes and mechanisms for capability reporting and QoS parameter distribution, with minimal impact on the system.
