Problems solved by technology

However, when people enjoy the high-speed traffic service of the train, the problem of high call drop rate during mobile communication also occurs
This is mainly because the mobile terminal sends a measurement report to its RNC, and the RNC makes a handover decision based on the measurement report. The following situation may occur: that is, the RNC has not yet analyzed the measurement report for the target base station, and has not notified the target base station to establish a connection with the terminal, but the RNC has already The analysis shows that the signal quality between the terminal and the original base station has deteriorated and no longer meets the connection conditions, and the RNC instructs the terminal to disconnect from the original base station. At this time, the terminal is disconnected from the original base station but has not yet connected to the target base station. , which causes the mobile terminal to drop the call

Embodiment 1

[0028] figure 1 It is a schematic flow diagram of an embodiment of the high-speed train communication management method of the present invention, as figure 1 As shown, the method of this embodiment may include:

[0029] 101. The high-speed train communication management device acquires the seat information of the high-speed train passengers, the terminal identification information of the mobile terminals of the high-speed train passengers, and the route information of the high-speed train;

[0030] Wherein, the high-speed train communication management device can be arranged at the front of each carriage of the high-speed train. The high-speed train communication management device can acquire passenger seat information and terminal identification information of passenger mobile terminals in various ways.

[0031] For example, before the high-speed train starts, when the passengers on the high-speed train get on the train, if the passenger wants to enjoy the communication ser...

Embodiment 2

[0055] figure 2 It is a schematic structural diagram of an embodiment of a communication management device for a high-speed train of the present invention. The device can be installed at the head of each car of the high-speed train, and the device can execute the method described in any embodiment of the present invention.

[0056] like figure 2 As shown, the device may include: a measurement reporting module 21, a connection processing module 22, and a vehicle speed reporting module 23; wherein,

[0057] The measurement reporting module 21 is configured to send a measurement report to the RNC, the measurement report includes the wireless signal parameters of the base station measured by the high-speed train communication management device, so that the RNC determines that the signal quality meets the requirements according to the wireless signal parameters. The base station of the connection condition is the target base station;

[0058] The connection processing module 22 i...

Embodiment 3

[0064] image 3 It is a schematic structural diagram of a base station embodiment of the present invention, and the base station executes the method described in any embodiment of the present invention. like image 3 As shown, the base station may include: a connection establishment processing module 31 and a switching time prediction module 32 .

[0065] Wherein, the connection establishment processing module 31 is used for sending a wireless link connection request for establishing a connection to the high-speed train communication management device according to the instructions of the RNC, and the sending time of the wireless link connection request is the first time, so that The high-speed train communication management device establishes a connection with the target base station according to the wireless link connection request; the indication is the wireless signal parameter determination signal of the RNC in the measurement report sent by the high-speed train communica...

Abstract

The invention provides a high speed train communication management method, an apparatus thereof and a system thereof. The method comprises the following steps: a high speed train communication management device arranged at a high speed train compartment head sends a measurement report to an RNC; the high speed train communication management device receives a wireless link connection request sent by a target base station at a first time; the high speed train communication management device reports a train speed of the high speed train at a first time to a target base station such that the target base station calculates a time difference between a wireless link connection time of a wireless terminal corresponding to each passenger and the first time according to seat information and the train speed of each passenger in a high speed train compartment, and establishes connection with each mobile terminal respectively at the wireless link connection time. According to the method, the device and the system, communication cutting off rate in high speed train running can be reduced, and the communication quality of a user is raised.

Description

technical field [0001] The present invention relates to communication technology, in particular to a high-speed train communication management method, device and system. Background technique [0002] During the running of the train, the mobile terminals corresponding to the passengers in the train compartment will all involve the handover of the base station. The usual handover process is that the mobile terminal corresponding to the passenger connects with the original base station, periodically detects the signal quality of its surrounding base stations, and periodically sends a measurement report to the radio network controller (Radio Network Controller, RNC for short) to which it belongs. , the measurement report includes wireless signal parameters (for example, signal strength) of the corresponding base station. The terminal keeps moving. When the RNC judges that the signal quality of a surrounding base station meets the connection standard according to the reported wi...
