Base station handover is a concept proposed to solve the link connection problem when users pass through the border of multiple cells in the process of moving. Base station handover technology is an integral part of mobile communication system design. During a call, when the signal strength of the communication link is degraded or the user crosses the edge of the cell, the signal strength is low. In order to ensure the continuity of the call, it is necessary to Trigger the handover procedure, which plays a crucial role in maintaining the link connection to avoid degrading the user experience. Handover must be accurate and effective, that is, the number of handovers should be as small as possible and the success rate of handover should be as high as possible, otherwise it will cause network burden or affect the user's call quality.

In view of this, an embodiment of the present disclosure provides a method for switching base stations based on user services under high-speed mobility, as shown in FIG. 1 , including:

Step S101, the current base station acquires location information and service information of multiple mobile terminals located on a high-speed moving train, wherein the location information is collected by a GPS (Global Positioning System, Global Positioning System) module on the mobile terminal;

Step S102, the current base station determines the target base station according to the location information. During specific implementation, each base station stores the location information of the train route and other base stations, and the current base station can determine the target base station that the mobile terminal is about to access according to the real-time position of the mobile terminal and in combination with the train route;

Step S103, the current base station sets the location priority for each mobile terminal according to the location information, and sets the service priority for each mobile terminal according to the service information;

Step S104, the current base station calculates the comprehensive priority of the mobile terminal in combination with the location priority and the service priority;

Step S105, the current base station sequentially initiates a base station switching request of the mobile terminal to the target base station according to the order of comprehensive priority from high to low;

Step S106, in response to the target base station confirming the base station handover request, the current base station performs handover.

In the method provided in this embodiment, the current base station obtains the location information and service information of multiple mobile terminals on a high-speed moving train, and sets comprehensive priorities for multiple mobile terminals based on the location information and service information, so that multiple The mobile terminal switches to the target base station sequentially according to the comprehensive priority, which can ensure that the mobile terminal under high-speed movement can switch the base station in time and successfully before the communication quality drops, and solves the problem of call drop interruption caused by frequent switching and communication resources caused by group switching Insufficient and network congestion problems.

In related technologies, the current base station usually only initiates handover to the target base station based on location information, that is, it judges that when the mobile terminal is at the cell coverage boundary of the current base station, it initiates a handover to the target base station. In this handover mode, all mobile terminals The quality of service when the current base station initiates a handover is the same, but the ongoing services of each mobile terminal are different. This will inevitably lead to some mobile terminals with high quality of service requirements facing service failure every time the base station is handed over. The problem that the quality cannot meet the demand is especially obvious when the application site is transferred to a high-speed mobile vehicle. In view of this, the method provided by the embodiment of the present disclosure can make the mobile terminal with high quality of service requirements complete the handover to the target base station in advance, because the business information (that is, the quality of service requirement) is also added to the discrimination factor of the base station handover. At the same time, the location information in the discriminant factors of base station switching will not be affected, and mobile terminals with low quality of service requirements will not be affected to complete the switching before leaving the coverage of the current base station. Switching base stations solves the problem of call drop and interruption caused by frequent switching. At present, the base station initiates handover requests of mobile terminals in sequence according to the comprehensive priority, and at the same time solves the problems of insufficient communication resources and network congestion caused by group handover.

In a specific embodiment, the above-mentioned current base station realizes the handover of the mobile terminal to the target base station based on the Xn interface. The signaling of the Xn interface carries the following functions: provide reliable XnAP (Xn Application Protocol, Xn Application Protocol) message transmission through the Xn interface; provide network and routing functions; provide redundancy in the signaling network; support flow control and congestion control.

The mobile terminal in the embodiment of the present disclosure includes: a smart phone, a computer, and other devices controlled by a mobile user and capable of establishing a two-way communication connection with a base station.

In some embodiments, in step S103, the current base station sets the location priority for each mobile terminal according to the location information, including:

Step S201, the current base station acquires the position information of the head of the train and the position information of the rear of the train;

Step S202, the current base station divides the multiple mobile terminals into multiple groups according to the position information of the multiple mobile terminals, the position information of the front of the vehicle and the position information of the rear of the vehicle;

Step S203, the current base station sets group position priorities from high to low for each group in turn according to the distance between each group in all groups and the train head from near to far;

Step S204, the current base station sets the same location priority for all mobile terminals in the same group according to the location priority of the group.

During specific implementation, step S202 divides the multiple mobile terminals into multiple groups according to the position information of the multiple mobile terminals, the position information of the head of the vehicle and the position information of the rear of the vehicle, which may be grouped according to the compartments. The specific implementation method is as follows: the information such as the length of the carriage is stored in the current base station in advance, and the current base station groups multiple mobile terminals according to the carriage according to the position information of the mobile terminal and the information of the length of the carriage.

In another embodiment of the present disclosure, the base station handover method can also be applied to other high-speed mobile vehicles other than trains, including automobiles, ships, and aircraft. Correspondingly, in other application scenarios, the above-mentioned train head and train parking spaces are adjusted to other carrier parts known to those skilled in the art.

In some embodiments, the service information includes the service quality requirements of the mobile terminal. In step S103, the current base station sets service priority for each mobile terminal according to the service information, including:

Step S301, the current base station sets service priorities from high to low for each mobile terminal in turn according to QoS (Quality of Service) requirements. QoS means that a network can use various basic technologies to provide better service capabilities for designated network communications. It is a security mechanism of the network and a technology used to solve problems such as network delay and congestion. QoS of user terminals The higher the demand, the stricter the requirements on latency and throughput.

During specific implementation, in step S104, the current base station calculates the comprehensive priority of the mobile terminal in combination with the location priority and the service priority, which can be implemented in the following manner: assigning different weights to the location priority and the service priority, and then adding them together, The result is the composite priority.

In some embodiments, in step S105, the current base station initiates a base station switching request of the mobile terminal to the target base station, including:

Step S401, the current base station sets a handover threshold for each mobile terminal according to the quality of service requirement. Setting the switching threshold according to the quality of service requirements can further ensure that mobile terminals with high quality of service requirements can switch base stations in time and successfully before the communication quality drops;

Step S402, the current base station measures the channel quality data of the mobile terminal, and compares the channel quality data with the handover threshold of the mobile terminal;

Step S403, in response to the channel quality data of the mobile terminal being lower than the handover threshold of the mobile terminal, the current base station initiates a base station handover request of the mobile terminal to the target base station.

In a specific embodiment, step S403 further includes: in response to the channel quality data of the mobile terminal being lower than the handover threshold of the mobile terminal, the current base station initiates a base station handover request of the mobile terminal to the target base station, and notifies the target base station to reserve the Communication resources required by the mobile terminal, and sending handover information to the target base station and the mobile terminal for subsequent handover. Handover information includes: target cell ID (Identification), mobile terminal context information, SAE (System Architecture Evolution, system architecture evolution) bearer ID, SAE bearer QoS parameters, RRC (Radio Resource Control, radio resource control) context information.

In some embodiments, in step S105, the current base station initiates the base station handover request of the mobile terminal to the target base station, which also includes:

Step S404. In response to the fact that the channel quality data of the mobile terminal is not lower than the handover threshold of the mobile terminal, the current base station continues to measure the channel quality data of the mobile terminal until the channel quality of the mobile terminal is lower than the handover threshold of the mobile terminal. It further ensures that mobile terminals with high quality of service requirements switch base stations in a timely and successful manner before communication quality declines.

In some embodiments, the channel quality data includes RSRP (Reference Signal Receiving Power, reference signal receiving power) data and RSRQ (Reference Signal Receiving Quality, reference signal receiving quality) data. RSRP is one of the key parameters that can represent the strength of wireless signals in LTE networks and one of the physical layer measurement requirements. It is the average value of the received signal power on all REs (Resource Elements) that carry reference signals within a certain symbol. RSRQ stands for LTE (Long Term Evolution, Long Term Evolution) Reference Signal Received Quality, which is mainly used to sort different LTE candidate cells according to the signal quality.

In some embodiments, the current base station sets the first service priority and the first switching threshold for video calls and voice call services; the base station sets the second service priority and the second service priority for non-session video and TCP (Transmission Control Protocol) services. The second switching threshold: the first service priority is higher than the second service priority, and the first switching threshold is higher than the second switching threshold.

In some embodiments, step S106 includes: the target base station confirms the remaining resources, and returns confirmation information to the current base station through the Xn interface. In response to receiving the target base station confirming the base station switching request, the current base station forwards the unprocessed resources to the target base station through the Xn interface. Cache the data, and perform the switch.
