Embodiment 1

[0021] User 1 and User 2 access wireless terminal access point A through WiFi, and user 3 and user 4 access wireless terminal access point B through WiFi, and the two wireless terminal access points respectively access eNodB through LTE technology, thereby ensuring that users Can access the network. The access point controller AC controls the wireless terminal access point A and the wireless terminal access point B, and the two wireless terminal access points work on a non-orthogonal channel at the WiFi access side.

[0022] Then, if figure 1 As shown, follow the steps below to power control the wireless access point:

[0023] S110 acquires the communication quality information and communication time of the access user of the wireless terminal access point and the backhaul side channel capacity of the wireless terminal access point;

[0024] S120 Calculate the access-side port traffic of the wireless terminal access point according to the communication quality information an...

Embodiment 2

[0049] The networking mode of this embodiment is the same as that of Embodiment 1. Similarly, user 1 and user 2 access wireless terminal access point A through WiFi, user 3 and user 4 access wireless terminal access point B through WiFi, and the two wireless terminal access points respectively access eNodB through LTE technology, This ensures that users can access the network. The access point controller AC controls the wireless terminal access point A and the wireless terminal access point B, and the two wireless terminal access points work on a non-orthogonal channel at the WiFi access side.

[0050] The AC periodically collects the communication quality information of the access users of the wireless terminal access point A and the wireless terminal access point B, and the backhaul side received signal strength indicators of the two wireless terminal access points. Wherein, the communication quality information of the access user includes information such as communication ...

Abstract

The present invention provides a method and system for power control of a wireless terminal access point, the method comprising: acquiring communication quality information and communication time of an access user of the wireless terminal access point and a backhaul side channel of the wireless terminal access point capacity; calculate the access side port traffic of the wireless terminal access point according to the communication quality information and communication time of the access user, and calculate the bearable backhaul side of the wireless terminal access point according to the backhaul side channel capacity flow rate; judging the flow rate of the port on the access side and the amount of flow that can be tolerated by the backhaul side; when the flow rate of the port on the access side is greater than or equal to the flow rate that can be tolerated by the backhaul side, reduce the transmission power of the access side. The present invention considers the communication capacity of the access side and the return side at the same time, and can adjust the power of each wireless terminal access point working on the non-orthogonal channel to a proper power.

Description

【Technical field】 [0001] The present invention relates to the technical field of wireless communication, in particular to a power control method and system for a wireless terminal access point. 【Background technique】 [0002] LTE (Long Term Evolution, long-term evolution) technology is developing very rapidly. With the maturity of LTE technology, domestic LTE industrialization has started, and many LTE products have been produced. At present, the networking mode using WLAN as the access technology and LTE technology as the transmission technology on the backhaul side is an important networking mode for LTE products. In order to reduce the mutual interference between devices on the access side and the radiation to the environment, it is necessary to control the power of the access point. The traditional power control method is based on the throughput and delay of the AP (Access Point, wireless access point) port. When the channel state changes, the power can be dynamically a...
