Base station handover is a concept proposed to solve the problem of link connection when a user passes at a multi-cell boundary during movement. The base station handover technology is an indispensable part in the design of a mobile communication system, when the signal strength is low due to the degradation of the signal quality of a communication link or the fact that a user crosses the edge of a cell in the calling process, in order to ensure the continuity of a call, a handover procedure needs to be triggered at this time, and the handover plays a crucial role in maintaining the link connection so as to avoid the reduction of user experience. The handover must be accurate and efficient, i.e. with as few handovers as possible and as high a success rate of the handover as possible, otherwise it will cause a burden on the network or affect the user's speech quality.
In view of this, an embodiment of the present application provides a method for switching a base station based on user services under high-speed mobility, as shown in fig. 1, including:
s101, the current base station acquires the position information and the service information of a plurality of mobile terminals on a train moving at a high speed. The location information is collected by a GPS module on the mobile terminal.
And S102, the current base station determines a target base station according to the position information. When the method is implemented specifically, each base station stores the position information of the train route and other base stations, and the current base station can determine the target base station to which the mobile terminal is about to access by combining the train route according to the real-time position of the mobile terminal.
S103, the current base station sets position priority for each mobile terminal according to the position information and sets service priority for each mobile terminal according to the service information.
S104, the current base station combines the position priority and the service priority to calculate the comprehensive priority of the mobile terminal.
And S105, the current base station initiates base station switching requests of the mobile terminal to the target base station in sequence according to the sequence of the comprehensive priority from high to low.
S106, responding to the base station switching request confirmed by the target base station, and executing switching by the current base station.
In the method provided by this embodiment, the current base station acquires the location information and the service information of a plurality of mobile terminals located on a train moving at a high speed, and sets a comprehensive priority for the plurality of mobile terminals according to the location information and the service information, so that the plurality of mobile terminals are sequentially switched to the target base station according to the comprehensive priority, and the mobile terminals can be ensured to switch the base station successfully in time before the communication quality is reduced, thereby solving the problems of dropped call interruption caused by frequent switching, insufficient communication resources caused by group switching, and network congestion.
In the related art, the current base station usually initiates handover to the target base station only according to the location information, that is, it is determined that when the mobile terminal is located at the coverage boundary of the current base station cell, the handover to the target base station is initiated, and in this handover manner, the service quality of all the mobile terminals when the handover is initiated by the current base station is the same, but the services being performed by each mobile terminal are different, which inevitably causes a problem that some mobile terminals with high service quality requirements face a problem that the service quality cannot meet the requirements each time the base station is handed over, and this problem is particularly obvious when the application location is transferred to a high-speed mobile carrier. In view of this, in the method provided in the embodiment of the present application, since the service information (i.e., the qos requirement) is also added to the criterion factor of the base station handover, the mobile terminal with a high qos requirement can complete the handover to the target base station in one step, and meanwhile, the location information in the criterion factor of the base station handover is retained, and the mobile terminal with a low qos requirement is not affected to complete the handover before leaving the coverage area of the current base station, so that the mobile terminal under high-speed movement can be guaranteed to switch the base station in time and successfully before the communication quality is reduced, and the problem of dropped call interruption caused by frequent handover is solved. The current base station initiates the switching request of the mobile terminal in turn according to the comprehensive priority, and solves the problems of insufficient communication resources and network congestion caused by group switching.

S202, the current base station divides the mobile terminals into a plurality of groups according to the position information, the head position information and the tail position information of the mobile terminals.
S203, the current base station sets the group position priority from high to low for each group in sequence according to the distance from near to far between each group in all the groups and the train head.
And S204, the current base station sets the same position priority for all the mobile terminals in the same group according to the group position priority.
In specific implementation, the mobile terminals are divided into a plurality of groups according to the position information of the mobile terminals, the head position information and the tail position information, and the groups may be grouped according to carriages. The specific implementation mode is as follows: and storing information such as carriage length and the like in the current base station in advance, wherein the current base station groups the mobile terminals according to carriages according to the position information and the carriage length information of the mobile terminals.

s301, the current base station sets the service priority from high to low for each mobile terminal in sequence according to the QoS requirement (i.e. the QoS requirement). QoS (Quality of Service) refers to a network that can provide better Service capability for specified network communication by using various basic technologies, and is a security mechanism of the network, which is a technology for solving the problems of network delay and congestion, etc., and the higher the QoS requirement of a user terminal is, the stricter the requirements on delay and throughput are.
In specific implementation, the current base station in S104 calculates the comprehensive priority of the mobile terminal by combining the location priority and the service priority, and may be implemented in the following manner: and giving different weights to the position priority and the service priority, and adding the weights to obtain a result, namely the comprehensive priority.
In some embodiments, the initiating, by the current base station to the target base station, a base station handover request of the mobile terminal in S105 includes:

In some embodiments, the channel quality data comprises RSRP (i.e., reference signal received power) data and RSRQ (i.e., reference signal received quality) data. RSRP (Reference Signal Receiving Power) is one of the key parameters that can represent the wireless Signal strength in LTE networks and the physical layer measurement requirements, and is the average of the received Signal Power over all REs (resource elements) that carry Reference signals within a certain symbol.
