Fig. 1 is a schematic diagram of a communication system architecture provided in the present application.
Referring to fig. 1, a communication system 01 includes a network device 101 and a terminal 102; wherein the network device 101 is deployed using NSA mode. When the communication system 01 includes a core network, the network device 101 may also be connected to the core network. The network device 101 may also communicate with an Internet Protocol (IP) network 200, such as the Internet (Internet), a private IP network, or other data network. The network device provides services for terminals within the coverage area. For example, referring to fig. 1, network device 101 provides wireless access to one or more terminals within the coverage area of network device 101. In addition, the network devices can also communicate with each other.
The network device 101 may be a device for communicating with a terminal. The network device may be a relay station, an access point, a vehicle-mounted device, etc. In an end-to-end (D2D) communication system, the network Device may also be a terminal that functions as a base station. A terminal may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem with wireless communication capabilities, as well as various forms of User Equipment (UE), Mobile Station (MS), and the like.
In the related art, the coverage area of a base station of a 5G communication system is small, so that a terminal supporting the 5G communication system preferentially selects a 5G cell as a serving cell when the 5G cell exists around the terminal, and then the radius of the 5G cell is small, and the terminal frequently performs a cell switching process during the high-speed movement of the terminal, thereby increasing the power consumption of the terminal.
In order to solve the above problem, a communication method provided by an embodiment of the present application will be described in detail below with reference to fig. 2 to 3.
Referring to fig. 2, a flow chart of a communication method is provided in the embodiment of the present application. The present embodiment is exemplified by a communication method applied to a terminal. The communication method may include the steps of:
s201, monitoring the moving speed of the terminal.
Generally, the moving speed represents the distance that the terminal moves within a preset time period, and the terminal may monitor the moving speed through a motion sensor, for example: the terminal detects the moving speed through a built-in satellite positioning module. The terminal can periodically monitor the moving speed of the terminal, and the period can be determined according to actual requirements. For example: the terminal detects the moving speed of the terminal at intervals of 1 second.
And S202, controlling the 5G channel to be in a closed state and controlling the non-5G channel to be in an open state when the moving speed is smaller than the speed threshold.
The speed threshold may be pre-stored or pre-configured by the terminal, and the speed threshold may be determined according to actual requirements, which is not limited in the embodiment of the present application. And when the moving speed is less than the speed threshold value, the terminal controls the 5G channel to be in a closed state and controls the non-5G channel to be in an open state. The 5G channel is used for transmitting a channel of voice data and service data through the 5G cell, the terminal can be provided with a 5G switch, the 5G switch is used for controlling the opening or closing of the 5G channel, when the 5G channel is closed, the terminal can only transmit the voice data and the service data (calling and surfing the Internet) through the non-5G channel, the non-5G channel is used for transmitting the channel of the voice data and the service data through the non-5G cell, and the non-5G cell comprises a 4G cell, a 3G cell and a 2G cell. Wherein the channel is not a 5G channel. When the 5G channel is in an open state, the terminal preferentially transmits voice data and service data through the 5G cell. Due to the limitation of the deployment of the target 5G communication system, the terminal can always keep the non-5G channel in the open state, and only when the moving speed is greater than the speed threshold value, the 5G channel is controlled to be in the closed state; and when the moving speed is less than or equal to the speed threshold value, controlling the 5G channel to be in an opening state.
According to the above, when the moving speed of the terminal is greater than the speed threshold, it indicates that the moving speed of the terminal is too high, the terminal can control the 5G channel to be in the closed state and control the non-5G channel to be in the open state, and since the coverage of the non-5G cell is greater than that of the 5G cell, the number of times of cell switching can be reduced in the moving process of the terminal, so that the power consumption of the terminal caused by cell switching is reduced, and the endurance time of the terminal is prolonged.

The terminal can periodically measure the moving speed, the preset time length is the measurement period of the terminal, the size of the preset time length can be determined according to actual requirements, and the embodiment of the application is not limited. For example: the preset time is 5s, and the terminal measures the moving distance of the terminal within 5s through a GPS.
And S302, obtaining the moving speed of the terminal according to the preset time length and the distance.
