Illustratively, when the server receives a service data request of a target service T sent by a target terminal for the first time, the server will count the number N of the counter T To determine the counter N by adding 1 to the value of (2) T Including a target terminal, i.e. the first number having a value of 1, sending a service data request for the target service T. If the server receives the service data request of the target service T sent by the target terminal again, the server again sends the counter N T To determine the counter N by adding 1 to the value of (2) T Including two target terminals sending service data requests for the target service T, and so on.
In addition, timer C T Starting from zero, e.g. when the server first receives a service data request for a target service T sent by the target terminal, timer C T The corresponding time is the first second, and the terminal that first sends the service data request of the target service T is the first terminal (marked as UE T1 (v),) first terminal UE T1 The corresponding timer may be C T1 . Correspondingly, when the server receives the service data request of the target service T sent by the target terminal for the second time, the timer C T The corresponding time is the fourth second, and the terminal that sends the service data request of the target service T for the second time may be, for example, the second terminal (marked as UE T2 (ii) second terminal UE T2 The corresponding timer is C T2 And so on.
In one possible design, the target terminals that send the service data requests of the target service T may be determined as a setHe { UE ] T Aggregation { UE }, set T The timer corresponding to each target terminal in the set { C } is determined as a set { C } T }. It should be appreciated that the set { UE ] T The target terminals included in the set { C } are terminals that send service data requests (e.g., target service T) of the same target service T The timers included in the method are all timers corresponding to the terminals sending the service data requests (such as the target service T) of the same target service. Exemplary, set { UE ] T }＝{UE T1 、UE T2 、UE T3 、…UE Tn Set { C }, set T }＝{C T1 、C T2 、C T3 、…C Tn }。

Specifically, as shown in fig. 6, S203 includes:
s2031, when the first time length is less than or equal to the time threshold, the server determines, according to the first number and the terminal number threshold, a communication mode between the network device and the target terminal.
For example, assume a time threshold C 0 =5s, and at this time the first time length C T1 =4s, thus C T1 ≤C 0 And the server determines the communication mode of the network equipment and the target terminal according to the first quantity and the terminal quantity threshold value.
Also for example, assume a time threshold C 0 =5s, and at this time the first time length C T1 =6s, thus C T1 ＞C 0 The server updates the first quantity according to the first quantity and the terminal quantity threshold value, and determines that the network equipment and the target terminal communicate in a unicast mode; alternatively, the server redefines the first number.
It should be appreciated that the first number is counter N T The number of target terminals included in the list, and thus the server may also be based on the counter N T The number of target terminals included in the network and the terminal number threshold (denoted as N 0 ) And determining the communication mode of the network equipment and the target terminal.
Specifically, S2031 includes:
s20311, in the case where the first number is smaller than the terminal number threshold, the server determines that the network device communicates with the target terminal in a unicast manner.
As shown in fig. 7, at N T ＜N 0 The server determines that the network device and the target terminal communicate in a unicast mode, and at the moment, the server transmits the data of the target service to the network device and simultaneously transmits the communication mode to the network device, namely, the server informs the network device to transmit the data of the target service to the target terminal in the unicast mode; after receiving the communication mode sent by the server, the network device sends the data of the target service to the target terminal in a unicast mode.
Exemplary, suppose C 0 ＝5s，C T1 =4s, and N T ＝4，N 0 =5; then within 4s, set { UE ] T }＝{UE T1 、UE T2 、UE T3 、UE T4 }. For example, terminal UE T1 Service data request of target service is sent at 1s, and terminal UE T2 Service data request of target service is sent at the 2 nd s, and terminal UE T3 Service of transmitting target service at 3sData request, terminal UE T4 At 4s a service data request for the target service is sent. Due to N T ＜N 0 That is, the number of terminals transmitting the service data request of the target service does not reach the terminal number threshold within the time threshold, so that the server notifies the network device to the set { UE ] T The target terminal included in the data transmission method transmits the data of the target service in a unicast mode; after the network equipment receives the communication mode sent by the server, the network equipment sends the communication mode to the set { UE } in a unicast mode T The target terminal included in the } transmits the data of the target service.
It should be noted that the server may notify the first network device to the set { UE } T The target terminal included in the set transmits the data of the target service in a unicast manner, and also can inform the second network device to the set { UE } T The target terminal included in the procedure transmits the data of the target service in a unicast manner, and the embodiment of the present application is not particularly limited.
S20312, the server determines that the network device communicates with the target terminal in unicast and broadcast modes, in a case where the first number is greater than or equal to the terminal number threshold.
As shown in fig. 6, at N T ≥N 0 The server determines that the network device and the target terminal communicate in a unicast and broadcast mode, and at the moment, the server transmits the data of the target service to the network device while transmitting the data of the target service to the network device, namely, informs the network device to transmit the data of the target service to the target terminal in a unicast and broadcast mode; after receiving the communication mode sent by the server, the network device sends the data of the target service to the target terminal in a unicast and broadcast mode.
Exemplary, suppose C 0 ＝5s，C T1 =4s, and N T ＝5，N 0 =5; then within 4s, set { UE ] T }＝{UE T1 、UE T2 、UE T3 、UE T4 、UE T5 }. For example, terminal UE T1 Service data request of target service is sent at 1s, and terminal UE T2 Service data request of target service is sent at 2.5s, and terminal UE T3 Service data request of target service is sent at 3s, terminal UE T4 Service data request of target service is sent at 3.5s, and terminal UE T5 At 4s a service data request for the target service is sent. Due to N T ＝N 0 I.e. the number of terminals sending service data requests of the target service reaches the threshold of the number of terminals within the time threshold, whereby the server informs the network device to the set { UE ] T The target terminal included in the data transmission method transmits the data of the target service in a unicast and broadcast mode, and the network equipment receives the communication mode sent by the server and transmits the data to the aggregation { UE in the unicast and broadcast mode T The target terminal included in the } transmits the data of the target service.
Specifically, as shown in fig. 8 and 9, S20312 includes:
s20312a, determining, by the server, data of a traffic target that has been received by the first terminal, to obtain a first byte, if the first number is equal to the terminal number threshold; and determining data of the target service which has been transmitted by the target terminal except the first terminal in the first quantity to obtain a second byte.
Based on the above embodiment, exemplary, assume C 0 ＝5s，C T1 =4s, and N T ＝5，N 0 =5. At this point, the server determines that the first terminal (e.g., UE T1 ) The data of the traffic targets that have been received are a first byte (marked Px), and the server determines the target terminals (e.g., UE) other than the first terminal in the first number T2 、UE T3 、UE T4 、UE T5 ) The data of the target service that has been received is the second byte (labeled Py).
The timer C corresponding to the first terminal T1 And therefore the first terminal has received the most data of the traffic object within the time threshold. Similarly, the data of the traffic targets that have been received by the target terminals other than the first terminal within the time threshold are sequentially reduced.
For example UE T2 The data of the received business object is Py1,UE T3 The received data of the business target is Py2 and UE T4 The received data of the business target is Py3 and UE T5 The data of the business object that has been received is Py4. Wherein Py1 > Py2 > Py3 > Py4.
S20312b, updating the first byte by the server to be the first byte plus 1, and determining, by the server, that the network device and the target terminal in the first number start transmitting data of the target service from the updated first byte in a broadcast manner; and determining the difference value between the second byte and the first byte in the data of the target service transmitted by the target terminal except the first terminal in a unicast mode in the network equipment and the first quantity.
Specifically, the server transmits the data of the target service to the network device while transmitting the data of the target service to the network device, that is, notifies the network device to transmit the data of the target service to all target terminals in the first number from the updated first byte in a broadcast manner; and notifying the network device to send the difference value between the second byte and the first byte in the data of the target service except the first terminal to the target terminal in the first quantity in a unicast mode; after receiving the communication mode sent by the server, the network equipment sends the data of the target service to all target terminals in the first quantity from the updated first byte in a broadcasting mode; and transmitting the difference value between the second byte and the first byte in the data of the target service to the target terminals except the first terminal in the first quantity in a unicast mode.
It should be noted that, in the embodiment of the present application, the first network device may send, in a broadcast manner, the data of the target service to all the target terminals in the first number from the updated first byte; meanwhile, the second network equipment transmits the difference value between the second byte and the first byte in the data of the target service except the first terminal in the first quantity in a unicast mode, so that the time for the network equipment to transmit the target service data to the target terminal can be saved.
Illustratively, the first network device transmits data of the target service to all target terminals in the first number in a broadcast manner starting from the px+1th byte; meanwhile, the second network device supplements missing data to the target terminals except the first terminal in the first quantity in a unicast mode, namely bytes of Px-Py in the data of the target service are sent.
For example, the first network device broadcasts to the set { UE }, in a broadcast manner T }＝{UE T1 、UE T2 、UE T3 、UE T4 、UE T5 The target terminal in the (P) sends the data of the target service from the Px+1th byte; meanwhile, the second network equipment unicasts to the target terminal UE T2 Bytes of Px-Py1 in data of sending target service to target terminal UE T3 Bytes of Px-Py2 in data of sending target service to target terminal UE T4 Bytes of Px-Py3 in data of sending target service and data of sending target service to target terminal UE T5 And sending bytes of Px-Py4 in the data of the target service.
S20312c, when the first number is greater than the threshold number of terminals, the server determines that the network device and the target terminal at the current time start transmitting data of the target service in a broadcast manner, and determines that the network device and the target terminal at the current time transmit data of the missing target service in a unicast manner.
Illustratively, at the current time, the target terminal UE T6 A service request for acquiring the data of the target service is sent, and the server sends N T The value of (2) is increased by 1, i.e. N T =6, and will target terminal UE T6 Joining to set { UE ] T In { UE }, so that the set { UE } T }＝{UE T1 、UE T2 、UE T3 、UE T4 、UE T5 、UE T6 }. Due to the current time N T ＞N 0 The server thus determines the first network device and the target terminal UE at the current moment T6 Starting to transmit data of target service in a broadcast mode, and determining second network equipment and target terminal UE at current moment T6 Data of the missing target service is transmitted in a unicast manner.
For example, the server sends the network device a communication means, i.e. the server informs the first network device of the broadcasting partyTo target terminal UE T6 Transmitting data of the target service and notifying the second network equipment to the target terminal UE in a unicast mode T6 And sending the data of the missing target service. After the first network device and the second network device receive the communication mode sent by the server, the first network device sends the communication mode to the target terminal UE in a broadcasting mode T6 Transmitting data of the target service, and the second network equipment unicasts the data to the target terminal UE T6 And sending the data of the missing target service.
In the embodiment of the application, the server can determine the communication mode between the network equipment and the target terminal according to the first quantity and the terminal quantity threshold within the time threshold, and the server determines that the network equipment and the target terminal transmit the target service data in a unicast mode under the condition that the first quantity is smaller than the terminal quantity threshold, so that the same times of data retransmission and transmission are reduced, and the resource waste is avoided; under the condition that the first quantity is equal to the threshold value of the quantity of the terminals, the server determines that the first network equipment and all target terminals in the first quantity transmit target service data in a broadcasting mode, and determines that the second network equipment and all target terminals except the first terminal transmit the missing target service data in a unicast mode in the first quantity, so that on one hand, all target terminals included in the first quantity can receive the target service data from the updated first byte at the same time, the total flow of network data is reduced, the utilization rate of network resources is improved, and the transmission load and the occupation of air interface resources are saved; on the other hand, the problem that part of target terminals cannot completely receive the data of all target services is solved; under the condition that the first number is larger than the threshold value of the number of the terminals, the server determines that the target service is a hot spot service, so that the first network equipment and the target terminal sending the request of the target service are notified to transmit service data in a broadcast mode, and the second network equipment is used for transmitting the data of the target service which is missing from the target terminal at the current moment in a unicast mode, namely, the server can dynamically determine whether the service data are required to be transmitted between the network equipment and the target terminal in a broadcast mode according to the change of the service request sent by the terminal in a certain area, and meanwhile, for the target terminal added later, the target terminal added later can also receive all the service data in a cooperative mode of the first network equipment and the second network equipment.

Exemplary, suppose C 0 ＝4s，C T1 =5s, and N T ＝4，N 0 =5; then within 5s, set { UE ] T }＝{UE T1 、UE T2 、UE T3 、UE T4 }. For example, terminal UE T1 Service data request of target service is sent at 1s, and terminal UE T2 Service data request of target service is sent at 3s, terminal UE T3 Service data request of target service is sent at 4s, and terminal UE T4 And sending a service data request of the target service at the 5 th s. Due to the terminal UE T4 Is that the service data request of the target service is sent at the 5 th s and exceeds the time threshold C 0 And N T ＜N 0 The server will therefore send the first terminal, i.e. the terminal UE T1 Deleting, updating the first number to a value of 3, i.e. the set { UE ] T }＝{UE T2 、UE T3 、UE T4 }. On the basis, the server determines the network device and the updated set { UE ] T All target terminals included in the list transmit the target traffic data in a unicast manner.
S20322, if the first number is greater than the terminal number threshold, re-determining the first number.
Exemplary, suppose C 0 ＝4s，C T1 =5s, and N T ＝6，N 0 =5; then within 5s, set { UE ] T }＝{UE T1 、UE T2 、UE T3 、UE T4 、UE T5 、UE T6 }. For example, terminal UE T1 Service data request of target service is sent at 1s, and terminal UE T2 Service data request of target service is sent at the 2 nd s, and terminal UE T3 Service data request of target service is sent at the 2 nd s, and terminal UE T4 Service data request of target service is sent at 4s, and terminal UE T5 Service data request of target service is sent at 4.5s, and terminal UE T6 And sending a service data request of the target service at the 5 th s. Due to the terminal UE T6 Is that the service data request of the target service is sent at the 5 th s and exceeds the time threshold C 0 And N T ＞N 0 The server thus re-determines the first number, i.e. from the terminal UE T6 Starting to recime, terminal UE T6 I.e. the first terminal in the next first number.
In the embodiment of the application, under the condition that the first time length is larger than the time threshold, the first number is firstly determined to be smaller than or equal to the terminal number threshold, namely, the number of terminals requesting to acquire the data of the target service at the current time is smaller, so that the server determines that the network equipment and the target terminal communicate in a unicast mode, the operation of repeatedly determining the first number is avoided, and the reduction of power consumption is facilitated; and when the first quantity is determined to be larger than the terminal quantity threshold value, the first quantity is redetermined, so that the reliability of the communication system is improved.
S204, the server sends a communication mode to the network equipment so that the network equipment and the target terminal can communicate by adopting the communication mode.
In summary, after the server determines the communication mode between the network device and the target terminal, the server sends the communication mode to the network device, so that the network device sends the data of the target service to the target terminal in the communication mode.
