In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following description describes related technologies of the embodiments of the present application, and the following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as alternatives, which all belong to the protection scope of the embodiments of the present application.

In some scenarios, multiple terminals may combine to handle a task. In the following, a federal learning task is described as an example, and a plurality of terminals are combined to process one learning task for the federal learning task.

Fig. 2-1 is a diagram of a federal learning architecture, as shown in fig. 2-1, the application server 210 interacts with a plurality of terminals (240-1 to 240-n) through a mobile network (core network 220+base station 230), for example, the application server 210 issues data to the plurality of terminals (240-1 to 240-n) through the mobile network, and the plurality of terminals (240-1 to 240-n) report data to the application server 210 through the mobile network. Due to the application layer scheduling requirement, the application server can select different terminals to participate in federal learning in each iteration (or each time period). As an example, there are 100 terminals under the coverage area of the base station, the application server interacts with 10 terminals therein as needed in each iteration (or each time period), so that the 10 terminals can report the trained results (simply referred to as the trained results, e.g. the trained model) to the application server through the local data, and the application server further processes (e.g. merges) the trained results of the 10 terminals. The application server may then start the next iteration (next time period) and reselect 10 terminals to start a new round of training and reporting results. Fig. 2-2 shows a schematic diagram of each iteration process of federal learning, here illustrated by an nth iteration process and an n+1st iteration process, including three processes of terminal selection, model allocation and training configuration, and reporting training results for each iteration process. It should be noted that, for a round of iterative process, a round of training process may also be described.

For federal learning, there are at least the following benefits: on one hand, local data of each terminal cannot be exposed, so that the data privacy is effectively protected; on the other hand, the calculation force is shared to a plurality of terminals, so that the training process of the model is accelerated; in yet another aspect, training of the model is based on local data of multiple terminals, breaking the data island problem.

Although the above description is described by taking federal learning as an example, any task that is jointly processed by a plurality of terminals or a task that is processed by a group may involve scheduling a plurality of terminals to process the task. When multiple terminals combine to process a task, the multiple terminals consume communication resources. If communication resources of a plurality of terminals are called without limit, normal operation of other terminals or other services is affected, and therefore an effective control mode is needed to limit the communication resources, so that the communication resources can be limited as required, and dynamic scheduling of the plurality of terminals is supported. For this reason, the following technical solutions of the embodiments of the present application are provided. The technical scheme of the embodiment of the application at least can be realized: 1. under the condition that the multi-terminal and the application server jointly perform a certain task, the communication resources (such as bandwidth) of the multi-terminal are limited; 2. under the condition that the multi-terminal and the application server jointly perform a certain task, the number of the multi-terminal is dynamically adjusted.

In order to facilitate understanding of the technical solution of the embodiments of the present application, the technical solution of the present application is described in detail below through specific embodiments. The above related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application. Embodiments of the present application include at least some of the following.

It should be noted that the technical solution of the embodiment of the present application may be applied to any communication system, including but not limited to a 5G system (5 GS), a 6G system (6 GS), etc.

It should be noted that, the technical solution of the embodiment of the present application may be applied to, but not limited to, federal learning scenarios, and may be applied to scenarios based on group management.

Fig. 3 is a flow chart of a communication method according to an embodiment of the present application, as shown in fig. 3, the communication method includes the following steps:

step 301: the mobile network control node triggers the mobile network execution node to establish connection between a plurality of terminals and the application server; the value of the first aggregation parameter of at least some of the plurality of terminals is smaller than or equal to a first total upper limit value and/or the value of the second aggregation parameter is smaller than or equal to a second total upper limit value, and the at least some of the plurality of terminals comprise at least one terminal for data transmission through respective connection.

In some alternative embodiments, the mobile network control node may be, but is not limited to being, a control plane network element, and the mobile network performing node may be, but is not limited to being, a user plane network element. As an example, taking a 5G network as an example, the mobile network control node may be a session management function network element (Session Management Function, SMF) and the mobile network performing node may be a user plane function network element (User Plane Function, UPF).

Here, the mobile network control node and the mobile network execution node may be set independently in the mobile network, or may be set in combination.

It should be noted that, in the embodiment of the present application, performing data transmission means: and data transmission is carried out between the terminal and the application server.

In some optional embodiments, before the mobile network control node triggers the mobile network execution node to establish connection between the plurality of terminals and the application server, the mobile network control node receives a first request message sent by the terminal and/or the application server; the first request message sent by the terminal is used for requesting to join the terminal into the group, and the first request message sent by the application server is used for requesting to join a plurality of terminals into the group.

The mobile network control node triggers the mobile network execution node to establish connection between a plurality of terminals and the application server, and the connection can be realized by the following modes: the mobile network control node sends a connection establishment or update message to a mobile network execution node, and receives a connection establishment or update reply message sent by the mobile network execution node, wherein the mobile network execution node is used for establishing connection with the application server for the plurality of terminals. Here, the first request message may alternatively be referred to as a join request message, which is used to request joining of a group.

In some alternative embodiments, the first request message carries request information including at least one of:

The first indication information is used for indicating the terminal to apply for joining the group;

The group identifier is used for indicating a group to which the terminal applies to join or a group to which the terminal belongs;

the terminal identification is used for identifying the terminals joining the group;

And the second indication information is used for indicating relevant service quality (Quality of Service, qoS) parameters when the terminal joins the group for data transmission.

Here, the first indication information may be alternatively referred to as joining group indication information.

Here, optionally, the QoS parameter indicated by the second indication information may indicate a highest or lowest QoS requirement of the terminal for transmitting data in the connection, for example, a maximum or minimum bandwidth requirement (such as a guaranteed bit rate and/or a maximum bit rate), a maximum or minimum delay requirement, a maximum or minimum reliability requirement, and so on. When the mobile network executing node establishes connection of the terminal, the mobile network executing node can establish connection meeting the corresponding QoS requirement according to the QoS parameter indicated by the terminal in the first request message. Here, the connection may be a QoS flow (QoS flow) or other connection with an execution QoS parameter.

As an example: the terminal 1 (which may be any one of a plurality of terminals) sends a first request message to the mobile network control node, the first request message carrying request information, the request information including at least one of:

the first indication information is used for indicating the terminal 1 to apply for joining the group;

The group identifier is used for identifying a group to which the terminal 1 applies to join;

A terminal identifier, where the terminal identifier is used to identify a terminal 1 joining a group;

and second indication information, where the second indication information is used to indicate QoS parameters related to the case that the terminal 1 joins the group to perform data transmission.

As an example: the application server sends a first request message to the mobile network control node, wherein the first request message carries request information, and the request information comprises at least one of the following components:

The first indication information is used for indicating the terminals 1 to N to apply for joining the group, wherein N is a positive integer;

The group identifier is used for identifying a group which is applied to be added by the terminals 1 to N;

a terminal identification list (i.e., a plurality of terminal identifications) for identifying the terminals 1 to N joining the group;

And the second indication information is used for indicating the terminal 1 to the terminal N to join in the group to perform data transmission and respectively related QoS parameters.

In some optional embodiments, the mobile network control node selects the same mobile network execution node for the plurality of terminals based on the request information, so, because the plurality of terminals correspond to the same mobile network execution node, when the plurality of terminals communicate with the mobile network execution node, group-level control of the plurality of terminals, that is, overall control of the plurality of terminals, and in particular, the mobile network execution node may control data transmission of the plurality of terminals based on a total upper limit value.

In some alternative embodiments, before the mobile network control node receives the first request message sent by the terminal and/or the application server, the mobile network control node receives a second request message sent by the first node, where the second request message carries a group policy. Further optionally, the mobile network control node establishes a group level context based on the group policy and sends the group level context to the mobile network enforcement node. Here, optionally, the first node is a unified data management node or a policy control node or an application server. Taking a 5G network as an example, the Unified data management node may be a Unified data management network element (Unified DATA MANAGEMENT, UDM), and the policy control node may be a policy control function network element (Policy Control Function, PCF).

Here, the second request message may alternatively be referred to as a configuration request message.

In some alternative embodiments, the group policy includes at least one of: the first total upper limit value refers to an upper limit of a value of a first aggregation parameter of at least one terminal performing data transmission; the second total upper limit value refers to an upper limit of a value of a second polymerization parameter of at least one terminal performing data transmission; the maximum number of terminals of a group, which is an upper limit of the total number of terminals contained in one group; address information of the application server, such as IP address, port number, etc. of the application server.

In some alternative embodiments, the group level context includes at least one of the following information: group identification, group QoS, group member information.

Here, alternatively, the group QoS in the group level context may be determined by the mobile network control node based on a total upper limit value in the group policy, e.g. the total upper limit value is the total bandwidth, for which the group QoS is.

Here, optionally, the group identification and the group member information in the group level context may be selectively allocated by the mobile network control node, wherein the number of terminals included by the group member needs to be smaller than the maximum number of terminals of the group in the group policy.

In some optional embodiments, after receiving the first request message, the mobile network control node updates a group level context based on request information carried in the first request message; the mobile network control node sends the updated group level context to the mobile network execution node.

In some optional embodiments, the first total upper limit value is a total bandwidth, where the total bandwidth refers to an upper limit of a sum of bandwidths of data flows of at least one terminal performing data transmission; the value of the first aggregation parameter of at least some of the plurality of terminals is less than or equal to a first total upper limit value, which means that: and the sum of bandwidths of the data streams of at least part of the terminals is smaller than or equal to the total bandwidth.

In some optional embodiments, the second total upper limit value is a total number of terminals, where the total number of terminals refers to an upper limit of a total number of at least one terminal performing data transmission; the value of the second polymerization parameter of at least some of the plurality of terminals is equal to or less than a second total upper limit value, which means that: and the terminal number of at least part of terminals is smaller than or equal to the total terminal number.

In an embodiment of the present application, the mobile network executing node controls data transmission between at least some of the plurality of terminals and the application server based on the first total upper limit value and the second total upper limit value, which is described below with reference to fig. 4.

Fig. 4 is a second flow chart of a communication method according to an embodiment of the present application, as shown in fig. 4, where the communication method includes the following steps:

Step 401: the mobile network execution node controls data transmission between at least some of the plurality of terminals and the application server based on a first total upper limit value and/or a second total upper limit value, wherein the first total upper limit value refers to an upper limit of a value of a first aggregation parameter of at least one of the plurality of terminals performing data transmission, and the first total upper limit value refers to an upper limit of a value of a first aggregation parameter of at least one of the plurality of terminals performing data transmission.

It should be noted that "data transmission is required" described in the following embodiments means "data transmission is required when data transmission is not yet performed".

Case one

In some alternative embodiments, the first total upper limit value is a total bandwidth, where the total bandwidth refers to an upper limit of a sum of bandwidths of data flows of at least one terminal performing data transmission.

Scheme 1-1) the mobile network execution node determines that the sum of bandwidths of data streams of at least one terminal performing data transmission with an application server is less than or equal to a total bandwidth, and allows the data streams of the at least one terminal to be transmitted to the application server through the mobile network execution node; if the sum of the bandwidth of the data stream of the first terminal needing to perform data transmission with the application server and the bandwidth of the data stream of the at least one terminal is larger than the total bandwidth, the mobile network execution node prohibits the data stream of the first terminal from being transmitted to the application server through the mobile network execution node; or if the sum of the bandwidth of the data stream of the first terminal needing to perform data transmission with the application server and the bandwidth of the data stream of the at least one terminal is less than or equal to the total bandwidth, the mobile network execution node allows the data stream of the first terminal to be transmitted to the application server through the mobile network execution node; wherein the first terminal is one of the plurality of terminals.

Scheme 1-2) if the mobile network executing node determines that the sum of bandwidths of data streams of at least one terminal performing data transmission with an application server is greater than or equal to the total bandwidth, the mobile network executing node prohibits the data stream of the first terminal that needs to perform transmission with the application server from being transmitted to the application server through the mobile network executing node.

Here, the first terminal that needs to perform data transmission may be understood as a new terminal that needs to perform data transmission (distinguishing from the at least one terminal that has performed data transmission).

Further, in some optional embodiments, if the second terminal in the at least one terminal stops transmitting, and the bandwidth of the data stream of the second terminal is greater than or equal to the bandwidth of the data stream of the first terminal, the mobile network execution node allows the data stream of the first terminal to be transmitted to the application server through the mobile network execution node; or if the second terminal in the at least one terminal stops transmitting, and the sum of the bandwidth of the data stream of the first terminal and the bandwidth of the data stream of the terminals except the second terminal in the at least one terminal is smaller than or equal to the total bandwidth, the mobile network execution node allows the data stream of the first terminal to be transmitted to the application server through the mobile network execution node.

Here, the second terminal may be understood as a terminal that has already performed data transmission.

As an example: and the terminal 1, the terminal 2, the terminal 3 and the terminal 4 perform data transmission, the sum of bandwidths of the data streams of the 4 terminals is less than or equal to the total bandwidth, and the mobile network execution node allows the data streams of the 4 terminals to pass through. Subsequently, the terminal 5 needs to perform data transmission, and if the sum of the bandwidth of the data stream of the terminal 5 and the bandwidths of the previous 4 terminals is greater than the total bandwidth, the mobile network executing node prohibits the data stream of the terminal 5 from passing through; further, if the terminal 1 of the previous 4 terminals stops transmitting and the bandwidth of the data stream of the terminal 1 is equal to or greater than the bandwidth of the data stream of the terminal 5, the mobile network execution node allows the data stream of the terminal 5 to pass.

Case two

In some alternative embodiments, the second total upper limit value is a total number of terminals, where the total number of terminals refers to an upper limit of a total number of at least one terminal performing data transmission.

Scheme 2-1) the mobile network execution node determines that the number of terminals of at least one terminal performing data transmission with an application server is less than or equal to the total number of terminals, and allows the data stream of the at least one terminal to be transmitted to the application server through the mobile network execution node; if the number of terminals of the first terminal which needs to perform data transmission with the application server plus the number of terminals of the at least one terminal is greater than the total number of terminals, the mobile network execution node prohibits the data flow of the first terminal from being transmitted to the application server through the mobile network execution node; or if the number of terminals of the first terminal which needs to perform data transmission with the application server plus the number of terminals of the at least one terminal is smaller than or equal to the total number of terminals, the mobile network execution node allows the data stream of the first terminal to be transmitted to the application server through the mobile network execution node; wherein the first terminal is one of the plurality of terminals.

Scheme 2-2) if the mobile network executing node determines that the number of terminals of at least one terminal performing data transmission with the application server is greater than or equal to the total number of terminals, the mobile network executing node prohibits the data stream of the first terminal that needs to perform transmission with the application server from being transmitted to the application server through the mobile network executing node.

Further, in some alternative embodiments, the mobile network execution node allows the data flow of the first terminal to be transmitted to the application server through the mobile network execution node if a second terminal of the at least one terminal stops transmitting.

As an example: and the terminals 1,2, 3 and 4 perform data transmission, the number of the terminals of the 4 terminals is less than or equal to the total number of the terminals, and the mobile network execution node allows the data flow of the 4 terminals to pass through. Subsequently, the terminal 5 needs to perform data transmission, if the number of terminals 5 plus the previous 4 terminals is greater than the total number of terminals, the mobile network executing node prohibits the data flow of the terminal 5 from passing through; further, if the terminal 1 of the first 4 terminals stops transmitting, the mobile network executing node allows the data flow of the terminal 5 to pass through.

Case three

In some optional embodiments, the first total upper limit value is a total number of terminals, where the total number of terminals refers to an upper limit of a total number of at least one terminal performing data transmission; the second total upper limit value is a total number of terminals, and the total number of terminals refers to an upper limit of the total number of at least one terminal performing data transmission.

The mobile network executing node determines that the sum of bandwidths of data streams of at least one terminal for data transmission with an application server is smaller than or equal to the total bandwidth, and the number of the terminals of the at least one terminal is smaller than or equal to the total number of the terminals, so that the data streams of the at least one terminal are allowed to be transmitted to the application server through the mobile network executing node;

If the sum of the bandwidth of the data stream of the first terminal needing to perform data transmission with the application server plus the bandwidth of the data stream of the at least one terminal is greater than the total bandwidth, and/or the number of terminals of the first terminal plus the number of terminals of the at least one terminal is greater than the total number of terminals, the mobile network executing node prohibits the data stream of the first terminal from being transmitted to the application server through the mobile network executing node; or alternatively

And if the sum of the bandwidth of the data stream of the first terminal which needs to perform data transmission with the application server and the bandwidth of the data stream of the at least one terminal is smaller than or equal to the total bandwidth, and the number of the terminals of the first terminal and the number of the terminals of the at least one terminal are smaller than or equal to the total number of the terminals, the mobile network execution node allows the data stream of the first terminal to be transmitted to the application server through the mobile network execution node.

As an example: and the terminal 1, the terminal 2, the terminal 3 and the terminal 4 perform data transmission, the sum of bandwidths of data streams of the 4 terminals is smaller than or equal to the total bandwidth, the number of the 4 terminals is smaller than or equal to the total number of the terminals, and the mobile network execution node allows the data streams of the 4 terminals to pass through. Subsequently, the terminal 5 needs to perform data transmission, if the sum of the bandwidth of the data stream of the terminal 5 plus the bandwidth of the previous 4 terminals is greater than the total bandwidth and/or the number of terminals 5 plus the previous 4 terminals is greater than the total number of terminals, the mobile network executing node prohibits the data stream of the terminal 5 from passing through; further, if the terminal 1 of the previous 4 terminals stops transmitting and the bandwidth of the data stream of the terminal 1 is equal to or greater than the bandwidth of the data stream of the terminal 5, the mobile network execution node allows the data stream of the terminal 5 to pass.

In the above solution, the mobile network may control data transmission based on the total upper limit value in the following manner:

In one mode, the mobile network execution node continuously controls data transmission between at least some of the plurality of terminals and the application server based on the first total upper limit value and/or the second total upper limit value.

Here, the processing tasks between the plurality of terminals and the application server may be implemented by a persistence procedure, i.e. without an iterative procedure, in which case the mobile network performing node may continuously control the data transmission according to the scheme described above.

Mode two) the mobile network execution node controls data transmission between at least part of the plurality of terminals and the application server based on the first total upper limit value and/or the second total upper limit value in each iteration or each time period.

Here, the processing tasks between the plurality of terminals and the application server may be implemented by a multi-round iterative process, in which case the mobile network executing node may perform control of data transmission for each round of iteration (or a time period corresponding to each round of iteration) according to the above scheme, for example, re-statistics the bandwidth sum of the terminals for each round of iteration and comparing the bandwidth sum with the total bandwidth, and/or re-statistics the number of terminals and comparing the number of terminals with the total number of terminals, and control whether the data stream is allowed to pass based on the comparison result.

In some alternative embodiments, the mobile network performing node determines whether to start a new round of iteration based on at least one of the following information: user plane information associated with the iteration, time information associated with the iteration, control plane information associated with the iteration.

In particular, the mobile network performing node may determine whether to start a new round of iteration based on at least one of the following information: user plane information associated with the iteration, time information associated with the iteration, control plane information associated with the iteration. The user plane information associated with the iteration may be, for example, a tag (such as a Differential Service Code Point (DSCP) tag or a Type of Service (ToS) field on an IP packet header) on a packet, where the packet is sent by the application server for downstream and the packet is sent by the terminal for upstream. The control plane information associated with the iteration may be, for example, indication information sent by the mobile network control node to the mobile network execution node, the indication information being used to indicate to update the group members, or to establish or update a connection between a terminal in the group and an application server.

It should be noted that, in the technical solution of the embodiment of the present application, "connection" may refer to a QoS flow (QoS flow) or other connection with an execution QoS parameter, and the present application does not limit the type of "connection".

It should be noted that, the "bandwidth" in the technical solution of the embodiment of the present application may refer to a guaranteed Bit Rate (Guaranteed Bit Rate, GBR) or a Maximum Bit Rate (MBR). The technical solution of the embodiment of the present application may be applied to uplink or downlink, where for uplink, the bandwidth refers to uplink bandwidth (e.g., UL GBR and/or UL MBR), and for downlink, the bandwidth refers to downlink bandwidth (e.g., DL GBR and/or DL MBR).

It should be noted that, the technical solution of the embodiment of the present application may be applied to an uplink scenario, and accordingly, at least some of the plurality of terminals may send data to an application server. Or the technical scheme of the embodiment of the application can be applied to a downlink scene, and correspondingly, the application server can send data to at least part of the terminals.

The following describes the technical scheme of the embodiment of the present application with reference to specific application examples.

Application example 1

Fig. 5 is a schematic diagram of group communication with an application server according to an embodiment of the present application, and as shown in fig. 5, a certain number of terminals 530 may complete connection establishment (e.g. PDU session establishment and/or corresponding QoS flow) with the application server 510 through a mobile network (core network 520+base station 540). In each iteration process, a part of terminals in the group transmit data with the application server through the connection respectively established, and the value of the aggregation parameter of the part of terminals is smaller than or equal to the total upper limit value, for example: the sum of bandwidths of the data streams of the part of terminals is smaller than or equal to the total bandwidth, and/or the number of terminals of the part of terminals is smaller than or equal to the total number of terminals. Fig. 5 illustrates an nth round of iterative process and an n+1th round of iterative process, each round of iterative process may reselect a participating terminal, and terminals corresponding to different iterative processes may be identical or partially identical.

Application instance two

Fig. 6 is a schematic flow chart of group establishment and joining provided by the embodiment of the present application, as shown in fig. 6, including the following steps:

Step 601: the application server or the unified data management node or the policy control node sends a configuration request message to the mobile network control node, the configuration request message carrying the group policy.

Taking a 5G network as an example, the unified data management node may be a UDM and the policy control node may be a PCF.

In some alternative embodiments, the group policy includes at least one of: a total upper limit value; the maximum number of terminals of a group, which is an upper limit of the total number of terminals contained in one group; address information of the application server, such as IP address, port number, etc. of the application server.

In some alternative embodiments, the total upper limit value includes at least one of: a total bandwidth, which refers to an upper limit of a sum of bandwidths of data streams of at least one terminal performing data transmission; total number of terminals, which refers to an upper limit of the total number of at least one terminal performing data transmission.

Here, after the mobile network control node acquires the group policy, a group-level context may be established according to the group policy, where optionally, the group-level context includes at least one of the following: group identification, group QoS, group member information, etc. Further, the mobile network control node may interact with the mobile network performing node to also establish the relevant context on the mobile network performing node (or this step may be done in a subsequent step 603 as well).

Step 602a/b: the plurality of terminals and/or the application server send a join request message to the mobile network control node, the join request message carrying the request information.

Taking a 5G network as an example, the mobile network control node may be an SMF and the mobile network performing node may be a UPF.

Here, the request message is used to request to join the group, and the terminals in the group may be called by the application server at any time to perform task processing (that is, a part of the terminals that request to join the group may be selected to perform task processing). For task processing implemented by an iterative process, a portion of the terminals from the group may be reselected for each iteration process to perform task processing.

In some alternative embodiments, the request information includes at least one of: the first indication information is used for indicating the terminal to apply for joining the group; the group identifier is used for indicating a group to which the terminal applies to join or a group to which the terminal belongs; the terminal identification is used for identifying the terminals joining the group; and the second indication information is used for indicating the related QoS parameters when the terminal joins the group to perform data transmission.

Here, the join request message may be sent multiple times from the terminal and/or the application server, i.e. each time it may be implemented to join one or more terminals into the group.

Here, alternatively, the mobile network control node may select the same core network execution node for the terminal according to the request information, so as to facilitate group level control.

Here, the mobile network control node updates the local group level context each time it receives a join request message. Further, the mobile network control node may send the updated group level context to the mobile network performing node in a subsequent step 503.

Step 603: the mobile network control node sends a connection setup or update message to the mobile network performing node.

Here, optionally, the connection establishment or update message carries indication information, where the indication information is used to indicate a terminal requesting to join the group, so that the mobile network execution node establishes a connection between the terminal and the application server for the terminal requesting to join the group.

Here, the mobile network performing node may create corresponding connections (e.g., PDU sessions and/or QoS flows) for terminals requesting to join the group, respectively. For example: the mobile network performing node may create a corresponding connection for the terminal based on the address information of the application server in the group policy, the connection being used for transmitting data between the terminal and the application server.

Step 604: the mobile network executing node sends a connection setup or update reply message to the mobile network control node.

Further, after step 604, the mobile network control node performs user plane data flow control.

Application example three

In this application example, the group includes 10 terminals, and the numbers of the 10 terminals are respectively terminal 1, terminal 2, terminal 3, terminal 4, terminal 5, terminal 6, terminal 7, terminal 8, terminal 9, and terminal 10, and the 10 terminals establish connection with the application server. In each iteration, the sum of the bandwidths of the data streams of the terminals actually transmitting data cannot be greater than 5mbps of the total bandwidth.

The mobile network performing node may determine the bandwidth occupied by the data flow of each terminal by, but is not limited to, the following:

Mode one) the bandwidth established by the data stream of the terminal is the bandwidth occupied by the connection of the terminal, namely: how much bandwidth the connection of the terminal is established, how much bandwidth the data stream of the terminal occupies. Based on the above, the mobile network executing node may determine the bandwidth occupied by the data stream of the terminal according to the bandwidth corresponding to the connection of the terminal.

Mode two), the mobile network executing node receives the user plane information or the control plane information, and determines the bandwidth occupied by the data flow of the terminal according to the indication information carried in the user plane information or the control plane information. Taking the user plane information as an example, the user plane information may be sent to the mobile network executing node by an application server or a terminal, for example, the application server sends a downlink data packet carrying the indication information to the mobile network executing node, for example, the terminal sends an uplink data packet carrying the indication information to the mobile network executing node. Here, the application server or the terminal may send a data packet carrying the indication information to the mobile network performing node (for example, the indication information may be sent to the mobile network performing node at the beginning of each iteration or during each iteration), where the indication information indicates the bandwidth occupied by the data flow of the terminal. Here, optionally, the indication information may be carried in a header of the data packet.

As shown in fig. 7, in the first iteration, the terminals 1, 2, 3 and 4 perform data transmission with the application server through respective connections, bandwidths of data streams of the 4 terminals are 1mbps,1.5mbps,1.2mbps and 1.2mbps, and a sum of bandwidths of the data streams of the 4 terminals is 4.9mbps, and since the sum of bandwidths 4.9mbps is less than 5mbps of the total bandwidth, the mobile network executing node allows the data streams of the 4 terminals to pass through. When the terminal 5 needs to perform data transmission, the mobile network executing node prohibits the data stream of the terminal 5 from passing through since the sum of the bandwidth of the data stream of the terminal 5 of 0.5mbps plus the bandwidth of the previous 4 terminals of 4.9mbps is greater than the total bandwidth of 5 mbps. Further, if the terminal 1 stops data transmission, the mobile network execution node allows the data stream of the terminal 5 to pass through since the bandwidth 1mbps of the data stream of the terminal 1 is greater than the bandwidth 0.5mbps of the data stream of the terminal 5. Similarly, in the second iteration process, the terminal 2, the terminal 7 and the terminal 9 perform data transmission with the application server through respective connections, bandwidths of data streams of the 3 terminals are respectively 1.8mbps,1.2mbps and 2mbps, the sum of bandwidths of the data streams of the 3 terminals is 5mbps, and the mobile network executing node allows the data streams of the 3 terminals to pass through because the sum of bandwidths is 5mbps and is equal to the total bandwidth of 5 mbps. When the terminal 3 needs to perform data transmission, the mobile network execution node prohibits the data stream of the terminal 3 from passing through since the sum of the bandwidth of the data stream of the terminal 3 of 0.9mbps plus the bandwidths of the previous 3 terminals of 5mbps is greater than the total bandwidth of 5 mbps. Further, if the terminal 7 stops data transmission, the mobile network execution node allows the data stream of the terminal 3 to pass through since the bandwidth 1.2mbps of the data stream of the terminal 7 is greater than the bandwidth 0.9mbps of the data stream of the terminal 3. In this way, each iteration can ensure that the sum of bandwidths used by the group members does not exceed the total bandwidth.

Application example four

In this application example, the group includes 10 terminals, and the numbers of the 10 terminals are respectively terminal 1, terminal 2, terminal 3, terminal 4, terminal 5, terminal 6, terminal 7, terminal 8, terminal 9, and terminal 10, and the 10 terminals establish connection with the application server. In each iteration, the number of terminals actually performing data transmission cannot be greater than the total number of terminals 3.

As shown in fig. 8, in the first iteration, terminals 1,2 and 3 perform data transmission with the application server through respective connections, and the number of terminals of these 3 terminals is equal to the total number of terminals 3, so that the mobile network executing node allows the data streams of these 3 terminals to pass through. When the terminal 5 needs to perform data transmission, the mobile network execution node prohibits the data stream of the terminal 5 from passing through due to the limitation of the total number of terminals 3, regardless of the bandwidth of the data stream of the terminal 5. Further, if the terminal 1 stops data transmission, the mobile network executing node allows the data flow of the terminal 5 to pass. In the second iteration, terminals 3, 5 and 6 are in data transmission with the application server via their respective connections, the number of terminals of these 3 terminals being equal to the total number of terminals 3, so that the mobile network executing node allows the data streams of these 3 terminals to pass. When the terminal 4 needs to perform data transmission, the mobile network execution node prohibits the data stream of the terminal 4 from passing through due to the limitation of the total number of terminals 3, regardless of the bandwidth of the data stream of the terminal 4. Further, if the terminal 3 stops data transmission, the mobile network executing node allows the data flow of the terminal 4 to pass. In this way, each iteration can ensure that the sum of the terminal numbers of the group members does not exceed the total terminal number.

Although the third and fourth embodiments are described with reference to the control of the downlink data transmission, the technical solution of the embodiment of the present application is also applicable to the control of the uplink data transmission.

It should be noted that, although the third embodiment and the fourth embodiment are described with respect to the data transmission control performed in each iteration process as an example, the technical solution of the embodiment of the present application is also applicable to a scenario in which the iteration process is not considered, that is, the mobile network control node may continuously perform the data transmission control.

It should be noted that, the solutions of the third embodiment and the fourth embodiment may be implemented separately or in combination, that is, the data transmission is limited according to the total bandwidth and the total number of terminals, and the mobile network executing node allows the data streams of the terminals to pass only when the sum of the bandwidths of the data streams of the terminals actually performing the data transmission is equal to or less than the total bandwidth and the number of terminals is equal to or less than the total number of terminals.
