Problems solved by technology

[0005] However, the data transfer rate is determined based on the RSSI and throughput rate of the wireless device service between the server and the CPAD in the prior art, and in the process of determining the data transfer rate, the resolution of the video device is adjusted according to the communication environment. In the same existing data transmission system between the server and the home access device, the data transmission rate is determined based on the RSSI and the processing rate, and a part of the transmission data at the sending end is transmitted through the communication If the distance is lost, there is a problem in the existing sending end that the data that has not reached the determined transmission rate reaches the sending end; and, when the data transmission rate is determined, the definition of the video device is changed according to the wireless communication network, and the service of the wireless communication environment is improved. Difficulties with Quality of Service (QoS)

Embodiment Construction

[0018] Next, for the implementation of the method for controlling the data transmission rate between the server and the home access device of the present invention, refer to Figure 1-Figure 4 Describe in detail.

[0019] figure 1 It is illustrated that when the server 1 communicates with the home access device (CPAD) 2 through the wireless communication network, the RSSI is reduced in order to increase the communication distance. Here, reducing the large arrow symbol of the home access device 2 in the server 1 represents the magnitude of the RSSI value.

[0020] When the server 1 transmits data to the home access device 2 through the wireless communication network, the data transmission rate is determined solely based on the RSSI value fed back from the home access device 2 . According to the data loss in the transmission process, the home access device 2 will not be able to receive part of the original transmitted data volume.

[0021] figure 2 It is an explanatory diag...

Abstract

A method for controlling data transmission rate between server and home switched ¿C in device includes deciding data transmission rate according to RSSI when data transmission is carried out between said server and said device, obtaining D ¿C value of original data transmission rate to actual receiving rate when data from said server is received and then feeding D ¿C value back to server, deciding data transmission rate according to feedback value and applying decided value for next data transmission so as to compensate data loss through radio communication network.

Description

(1) Technical field [0001] The present invention relates to the technology of ensuring the quality of service (QoS) of the wireless communication environment according to the distance when transmitting data between the server and the home access device (hereinafter referred to as CPAD), especially regarding the strength of the received signal received through the wireless communication network as The basis is to analyze the data lost during the transmission process when adjusting the data transmission rate, so as to determine the transmission rate, a method for controlling the data transmission rate between the server and the home access device. (2) Background technology [0002] Recently, servers are installed in home appliances (such as refrigerators) used in places such as homes and offices to make it possible to attach and detach refrigerator doors, and transparent touch panels that complete data communication through servers and wirelessly have household interfaces Afte...
