Embodiment 1

[0042] Such as figure 1 As shown, this embodiment records a control plane and user plane adaptive power adjustment method, and the method includes the following steps:

[0043] S1: Determine the service area covered by the wireless network system, and the network center controller determines the service range and service capability required by the wireless network system according to different service nodes in the service area;

[0044] S2: The control plane of each service node adjusts the service range covered by the control plane of each service node by using power control according to the entire network environment;

[0045] S3: Each service node adjusts the service scope of the user plane of each service node according to the real-time distribution location of the user and the service quality requirement.

[0046] Specific steps are as follows:

[0047] Firstly, the service area covered by the wireless network system is determined, and the network center controller dete...

Embodiment 2

[0054] Such as figure 2 As shown, this embodiment records the control plane adaptive power adjustment method of Embodiment 1, including the following steps:

[0055] S21: The macro base station transmits with maximum power in the control channel, so that the control plane of the macro base station can cover the required service area and be larger than the service area covered by the user plane;

[0056] S22: The macro base station receives the service request sent by the user terminal, and allocates a base station within the control range of the macro base station to the user terminal in combination with the current resource usage and load conditions of the wireless network system;

[0057] S23: The macro base station obtains the path loss and the received power of the user terminal according to the distance from the base station to the user terminal and channel fading conditions;

[0058] S24: If the received power of the user terminal satisfies γ n ≥γ 0 , the base statio...

Embodiment 3

[0077] Such as image 3 As shown, this embodiment records the user plane adaptive power adjustment method of Embodiment 1, including the following steps:

[0078] S31: Through the data channel, the base station completes the data stream transmission process to the user terminal;

[0079] S32: According to the path loss from the base station to the user terminal and Shannon's theorem, obtain the data transmission rate of the base station based on the existing transmit power;

[0080] S33: If the transmission rate of the base station satisfies R≥R LE , enter step S35; otherwise adjust the transmit power of the base station, enter step S34;

[0081] S34: If the adjusted transmit power of the base station is greater than the maximum transmit power of the base station, deny the access of the base station; otherwise, return to step S32;

[0082] S35: According to the judgment criterion, select the base station with the best performance to access;

[0083] Among them, R is the tr...

Abstract

The invention discloses an adjusting method for self-adaptive power of a control plane and a user plane. The adjusting method comprises the following steps of: S1, confirming a service area covered by a wireless network system, and then confirming service scope and service capability required by the wireless network system by a network central controller according to different service nodes in the service area; S2, utilizing power control to adjust the service scope covered by the control plane of each service node by the control plane of each service node according to the whole network environment; and S3, adjusting the service scope of the user plane of each service node by each service node according to the distributing position and service quality requirement of a user in real time. According to the adjusting method for the self-adaptive power of the control plane and the user plane disclosed by the invention, the problem of serious interference in the prior art is solved and the use ratio of resources is high.

Description

technical field [0001] The invention relates to the technical field of wireless network communication, in particular to a control plane and user plane adaptive power adjustment method. Background technique [0002] With the further development of mobile communication technology and wireless network system, the reasonable allocation of wireless network resources and the continuous improvement of energy efficiency requirements, the traditional network networking methods have exposed more and more disadvantages. According to the survey, it is estimated that by 2020, the capacity demand of wireless networks will be 1000 times that of the current ones, and the capacity increase that can be obtained purely from wireless transmission technology is very limited. Therefore, the focus of research is on the composition of wireless networks. In terms of network mode and power allocation, the joint deployment and flexible cooperation of different types of service nodes are considered to ...
