Embodiment 1

[0036] Intelligent database execution method of the present invention comprises the following steps:

[0037] S1: After the AP is associated with at least one STA, determine whether there is an STA whose distance to the AP is less than the critical distance;

[0038] S2: If there is an STA whose distance to the AP is less than the critical distance,

[0039] The data transmission mode between the STA and the AP is changed from the multicast transmission mode to the unicast transmission mode, and the data transmission mode between the remaining STAs and the AP remains in the multicast transmission mode;

[0040] Otherwise, execute step S3;

[0041] S3: The data transmission mode between all STAs and the AP remains in the multicast transmission mode.

[0042] In step S1 or step S2, the data transmission method is directly determined by the critical distance, and the critical distance is determined by comparing the multicast scoring value obtained by using the multicast scoring...

Embodiment 2

[0059] This embodiment is similar to Embodiment 1, the difference is that this embodiment is a system for switching data transmission modes using the method of switching data transmission modes. Although each method has its own advantages, it also has its own disadvantages, which are as follows:

[0060] Advantages of unicast:

[0061] 1. The server responds to the client's request in a timely manner;

[0062] 2. The server sends different data according to different requests of each customer, which is easy to realize personalized service.

[0063] Disadvantages of unicast:

[0064] 1. The server is overwhelmed in streaming media applications with a large number of clients and a large flow rate per client;

[0065] 2. The existing network bandwidth is a pyramid structure. If all unicast protocols are used, the network backbone will be overwhelmed;

[0066] Multicast: "one-to-one group" communication mode between hosts, that is, hosts that join the same group can receive al...

Embodiment 3

[0076] This embodiment is similar to Embodiment 1, except that the critical distance in this embodiment is determined by the network properties and data transmission rate between the STA and the AP. In an open space, as the distance increases, the same network In the environment, the transmission rate is more or less affected, and the greater the distance change, the more obvious the impact. This embodiment adopts this property of the network, and judges the critical distance by the change of the transmission rate. The specific performance is: for example, under the 5G network, In an open space, the transmission rate is usually configured as 6Mbps, and the ATP with a reception rate attenuation of 5Mbps has a fixed distance from the AP. Of course, there will be a slight error in the distance, but the error range will be within an acceptable range. Within, this embodiment has the same advantages as the embodiment, that is, the calculation process is simple, etc., but the distance...

Abstract

The invention relates to a method for switching a data transmission mode. The method comprises the following steps: S1, after an AP is associated with at least one STA, judging whether the STA of which the distance with the AP is less than a critical distance exists; S2, if the STA of which the distance with the AP is less than the critical distance exists, switching the data transmission mode between the STA and the AP from a multicast transmission mode to a unicast transmission mode, and maintaining the data transmission modes between other STAs and the AP as the multicast transmission mode; and otherwise, performing step S3; and S3, maintaining the data transmission mode between all STAs and the AP as the multicast transmission mode. The method disclosed by the invention has the advantages that the AP can automatically detect the transmission state with the STA to adjust the transmission mode.

Description

technical field [0001] The invention belongs to the wireless local area network processing technology, in particular to a method and system for switching data transmission modes. Background technique [0002] With the continuous popularization of electronic devices, network-based wireless communication technology is also on the road to maturity. In many scenarios, an AP will be associated with a large number of STA mobile terminals to receive multicast at the same time. For example, in the existing technology, in In a classroom, when all students use pads to receive video lessons, they will use multicast to receive AP data, but there are many problems in using multicast regardless of the distance between STA and AP and the transmission rate. STA devices that may have better transmission quality reduce transmission quality due to receiving data in a multicast manner with other STAs. [0003] In order to solve the above technical problems, Chinese Patent No. discloses a wirel...
