On May 25, it was reported that Shanghai Huawei Technology Co.Ltd. published a patent for Communication energy-saving methods, devices, and related means in a high-speed railway case.
The method will work in the following ways, the first access network device received random access requests which will be sent by N terminals and sends an activation instruction to the second access network device for activating the second access network device in the dormant state.

Moreover, the N terminals remain in a high-speed train, the access network equipment is located along the train tracks, and the train passes through the coverage areas of the first and second access network equipment consecutively.
The current application reveals a communication energy-saving method in high-speed railways, which can be applied to the field of wireless communication as well.
The methods include, the first access network device receiving random access requests which are sent by the N terminals, and then sending an activation instruction to a second access network device, where the activation instruction is used to activate the second access network device in a dormant state.
The first access network device and the second access network device are located along the track on which the fast-moving train travels. Then the train passes through the coverage area of the first access network device and then passes through the compass area of the access network equipment.
Whenever there is no professional equipment on the fast-moving train, the second access network equipment can be activated normally to improve the user experience.
