Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the existing private network communication system, communication connection needs to be established between a dispatching desk and a relay station, the ability of the dispatching desk for monitoring the air interface activity of the relay station is realized, and communication between the dispatching desk and each terminal in the system is realized. In order to solve the problems existing in the prior art, the present application provides the following embodiments:

referring to fig. 1 to 3, the adaptive scheduling system of the present application includes a scheduling platform 11, a first relay station 12, and a vehicle platform 13. The first relay station 12 is in communication connection with the dispatching station 11 through a first connection mode, and is configured to acquire air interface data, upload the air interface data to the dispatching station 11, and relay an air interface service sent by the dispatching station 11. The vehicle platform 13 is in communication connection with the first relay station 12, and the vehicle platform 13 is in communication connection with the dispatching desk 11 through a second connection mode.

The first relay station 12 is further configured to detect whether the first connection mode is abnormal, if it is detected that the first connection mode is abnormal, the first relay station 12 generates first scheduling information, the first scheduling information is used to notify the vehicle platform 13 to enable the second connection mode to be in communication connection with the scheduling station 11, so that air interface data acquired by the first relay station 12 is uploaded to the scheduling station 11 through the vehicle platform 13, and air interface services sent by the scheduling station 11 are sent to the first relay station 12 through the vehicle platform 13. As shown in fig. 1, when the first relay station 12 detects an abnormality in the first connection method, the second connection method is activated by the vehicle mount 13.

The system further includes a user terminal 14, where the user terminal 14 is in communication connection with the first relay station 12 through an air interface (air interface, abbreviated as air interface), and the user terminal 14 is configured to send air interface data to the first relay station 12 and receive air interface services relayed by the first relay station 12. When the first connection mode is normal, the air interface data sent by the user terminal 14 is relayed to the dispatching desk 11 via the first relay desk 12, and the air interface service sent by the dispatching desk 11 is relayed to the user terminal 14 via the first relay desk 12. Air interface data sent among a plurality of user terminals 14 will also be uploaded to the dispatching desk 11 through the first relay desk 12, that is, the dispatching desk 11 has a monitoring function. When the first connection mode is abnormal, the air interface data sent by the user terminal 14 is transferred to the vehicle platform 13 via the first relay station 12 and then uploaded to the dispatching platform 11, and the air interface service sent by the dispatching platform 11 is transferred to the user terminal 14 via the vehicle platform 13 and the first relay station 12, so that communication between the user terminal 14 and the dispatching platform 11 is realized.

In this embodiment, the detection of whether the first relay station 12 is abnormal or not may be a continuous process, such as detection at regular intervals during the operation of the first relay station 12, for example, detection every 30 seconds.

In this embodiment, the air interface data may refer to data that is uplink to the scheduling station 11, for example, data sent by the relay station 12 or data (such as short message, multimedia message, voice, GPS, registration information, and the like) sent by the user terminal 14, and is uploaded to the scheduling station 11 through the first relay station 12, or data sent by other methods, such as data stored in a usb disk, a mobile hard disk, a cloud disk, and the like, is uploaded to the scheduling station 11 through the first relay station 12. Of course, the air interface data may also be sent between the user terminals 14, for example, the air interface data sent by one user terminal 14 is sent to another user terminal 14 after passing through the first relay station 12.

The air interface service may refer to data transmitted by the dispatching station 11 in a downlink manner, for example, the dispatching station 11 transmits data, and the data is transmitted to the user terminal 14 or the vehicle station 13 in a downlink manner through the first relay station 12. In this embodiment, relaying, by the first relay station 12, the air interface service sent by the dispatching station 11 means that the air interface service sent by the dispatching station 11 is relayed to the vehicle station 13 and/or the user terminal 14 through the first relay station 12.

In this embodiment, when the communication connection between the scheduling station 11 and the first relay station 12 is normal, the scheduling station 11 may monitor or sense the air interface activity of the first relay station 12, which includes air interface data between the user terminal 14 and the user terminal 14, air interface data that the user terminal 14 uplink to the scheduling station 11, air interface services downlink by the scheduling station 11 itself, and the like.

Generally, the first relay station 12 may correspond to multiple user terminals 14 at the same time, and when air interface data is transmitted between the user terminals 14, the relay is performed through the first relay station 12. In this embodiment, the user terminal 14 may be a mobile phone, a tablet, an intercom, or other smart devices, voice devices, etc. In one case, the user terminal 14 may uplink the null data to the scheduler 11 separately. In another case, the user terminal 14 uplink the air interface data to the dispatching station 11 through the first relay station 12, and the first relay station 12 may relay the air interface data to other user terminals 14, that is, other user terminals may also receive the air interface data.

As shown in fig. 2, in one scenario, in the default state, the first connection mode is normal, and the vehicle mount 13 disables the second connection mode. In another scenario, in a default state, the first connection mode is normal, and the second connection mode is also normal, but the dispatcher station 11 and the first relay station 12 preferentially perform communication connection through the first connection mode to transmit data. In this embodiment, the default state may be an initial state of the system, in which the first connection mode is normal, the vehicle platform 13 disables the second connection mode, and at this time, the entire system realizes the communication connection between the dispatching desk 11 and the first relay desk 12 through the first connection mode, so as to realize the data communication. Or, in the default state/initial state, the entire communication system operates with the first connection mode as the main communication line, and the second connection mode is the standby communication line, and is enabled in case of abnormality of the first connection mode. In other embodiments, the default state may be an initial state of the system, in which the first connection mode is normal and the second connection mode is normal (the vehicle station 13 does not disable the second connection mode), but the entire system preferentially implements communication connection between the dispatching station 11 and the first relay station 12 through the first connection mode to implement data communication, that is, the priority of the first connection mode is higher than the priority of the second connection mode.

In this embodiment, the first connection abnormality is, for example, disconnection, unstable connection, failure to normally transmit data, abnormal transmission rate, or other types of failures.

In this embodiment, in order to prevent that normal communication cannot be performed between the dispatching desk 11 and the first relay station 12 when the first connection mode is abnormal, whether the first connection mode is abnormal is detected through the first relay station 12, when the first connection mode is abnormal, the first relay station 12 generates first scheduling information and sends the first scheduling information to the vehicle platform 13, the vehicle platform 13 starts a second connection mode to be in communication connection with the dispatching desk 11 after receiving the first scheduling information, at this time, the dispatching desk 11 and the first relay station 12 are in communication connection through the vehicle platform 13, so that stable communication connection can be performed between the dispatching desk 11 and the first relay station 12 under the condition that the first connection mode is abnormal, so that air interface data acquired by the first relay station 12 can be uploaded to the dispatching desk 11 through the vehicle platform 13, and air interface services sent by the dispatching desk 11 can be sent to the first relay station 12 through the vehicle platform 13, the function of the dispatching desk 11 for monitoring the air interface activity of the first relay station 12 is ensured, and the data transmission and the work of the whole communication system are ensured.

With reference to fig. 2, optionally, when the first relay station 12 is further configured to recover to normal after detecting that the first connection mode is abnormal, the first relay station 12 generates second scheduling information and sends the second scheduling information to at least the vehicle mount 13, where the second scheduling information is used to notify the vehicle mount 13 to disable the second connection mode.

In this embodiment, after the first connection mode is abnormal, the first relay station 12 continues to perform detection or monitoring, and if it is detected that the first connection mode is recovered to normal, the first relay station 12 generates second scheduling information and sends the second scheduling information to the vehicle station 13 and the user terminal 14. The vehicle station 13 is notified that the second connection mode is disabled, and at this time, the first relay station 12 and the dispatching station 11 communicate with each other through the first connection mode. Through the above manner, the embodiment can realize automatic switching of the communication connection manner between the first relay station 12 and the dispatching station 11 under different conditions, and can ensure the effectiveness of communication between systems to a greater extent.

Optionally, the first scheduling information includes a first relay station ID, a vehicle station ID, and a first connection mode exception identifier. The second scheduling information includes a first relay station ID, a vehicle station ID, and a first connection mode normal identification.

In this embodiment, the first relay station ID is used to identify the relay station, and may be, for example, identity information unique to the relay station after manufacture and shipment, or identity information manually set in the relay station by software or the like. The same applies to the carriage ID. The first connection mode exception indicator is used to indicate that the first connection mode is abnormal, for example, if the first connection mode exception indicator is 1, the first connection mode exception indicator indicates that the first connection mode is abnormal. The first connection mode normal flag is used to indicate that the first connection mode is normal, for example, if the first connection mode normal flag is 0, it indicates that the first connection mode is abnormal.

Optionally, when the first relay station 12 returns to normal after detecting that the first connection mode is abnormal or abnormal, the first relay station 12 sends the first scheduling information or the second scheduling information to the vehicle station 13 and the user terminal 14 in a broadcast mode.

In this embodiment, the first scheduling information is correspondingly sent when the first connection mode is abnormal, the second scheduling information is correspondingly sent when the first connection mode is recovered to be normal, the second connection mode is enabled after the vehicle platform 13 receives the first scheduling information, and the second connection mode is disabled after the second scheduling information is received, so that the automatic switching of the connection modes is realized. In this embodiment, the transmission by broadcast enables the vehicle station 13 and other devices in the scheduling system, such as each user terminal 14, to receive synchronously, and ensures the effectiveness and synchronicity of scheduling switching.

Further, when the first relay station 12 detects that the first connection method is abnormal or returns to normal after the abnormality, the first relay station transmits the first scheduling information or the second scheduling information to the vehicle mount 13 and the user terminal 14 in a broadcast manner, the user terminal 14 switches to a first scheduling mode adapted to the first scheduling information when receiving the first scheduling information, and the user terminal 14 switches to a second scheduling mode adapted to the second scheduling information when receiving the second scheduling information. I.e. the first scheduling information is further used to inform the user terminal 14 to switch to a first scheduling mode adapted to the first scheduling information, and the second scheduling information is further used to inform the user terminal 14 to switch to a second scheduling mode adapted to the second scheduling information.

In this embodiment, when the vehicle platform 13 receives the first scheduling information or the second scheduling information, the first connection mode abnormal identifier or the first connection mode normal identifier is used to notify the vehicle platform 13 to enable or disable the second connection mode. Optionally, when the vehicle platform 13 receives the first scheduling information or the second scheduling information, the second connection mode may be enabled or disabled as long as the first connection mode abnormal identifier or the first connection mode normal identifier is identified. Of course, the vehicle station 13 may recognize the entire content of the first scheduling information or the second scheduling information and then enable or disable the second connection mode.

For the user terminal 14, due to different communication connection manners, there may be a difference in communication between the scheduling station 11 and the user terminal 14, for example, information fed back mutually between hardware is different, for example, different communication paths may have an influence on format, size, description information, and the like of data uploaded or received by the user terminal 14, or different feedback information between air interface activities of the first relay station 12 monitored by the scheduling station 11 under different communication paths, or different formats of data uploaded to the scheduling station 11. In order to avoid the problems that data transmission in the system is not matched with the communication path due to the communication path switching, the user terminal 14 needs to switch the corresponding scheduling mode to adapt to different communication paths when switching different communication connection modes. In the embodiment, after receiving the first scheduling information, the first relay station ID, the vehicle station ID, and the first connection abnormality identifier, the user terminal 14 can be used to notify the user terminal 14 that the first connection abnormality is present, and the user terminal 14 has switched to the second connection, and the dispatcher station 11 communicates with the first relay station 12 through the vehicle station 13 and the second connection, so as to notify the user terminal 14 to switch to the first scheduling mode, in which the user terminal 14 is adapted to the communication path of the "first relay station-vehicle station-dispatcher station". When the user terminal 14 receives the second scheduling information, the first relay station ID, the vehicle station ID and the first connection mode normal identifier can be used to notify the user terminal 14 that the first connection mode has recovered to normal and has been switched to the first connection mode, and the dispatcher station 11 and the first relay station 12 are in communication connection through the first connection mode, so as to notify the user terminal 14 to switch to the second dispatching mode, and in the second dispatching mode, the user terminal 14 is automatically adapted to the communication path of the "first relay station-dispatcher station". The user terminal 14 automatically switches different scheduling modes under different scheduling information, so that the communication between the user terminal 14 and the scheduling station 11 is more stable, and the effectiveness and matching degree of data transmission between the user terminal 14 and the scheduling station are ensured.

Optionally, when the first relay station 12 is in the dormant state, if the first relay station 12 detects that the first connection mode is abnormal or returns to normal after the first connection mode is abnormal, the first relay station 12 sends the first scheduling information or the second scheduling information to the vehicle station 13 and the user terminal 14 respectively in the first broadcast mode.

In this embodiment, the first relay station 12 detects the abnormality of the first connection mode or returns to normal after the abnormality, and is not necessarily detected in the sleep state, since it is also described above, the detection performed by the first relay station 12 may be a continuous process, for example, there is a time interval between two detections, and the sleep state occurs in the time interval, and is not detected in the sleep state. Therefore, the first connection mode is detected to be abnormal or to return to normal after the abnormality occurs, and the first connection mode can be in the idle state or in the idle state. When the first relay station 12 is in the sleep state, the first relay station 12 sends the first scheduling information or the second scheduling information to the vehicle station and the user terminal 14, respectively, in a first broadcast manner.

Optionally, when the first relay station 12 is in a non-sleep state and relays the voice information to the user terminal 14, if the first relay station 12 detects that the first connection mode is abnormal, the first relay station 12 sends the first scheduling information to the mobile station 13 and the user terminal 14 in the second broadcast mode.

Similarly, as described above, the first relay station 12 detects that the first connection mode is abnormal or returns to normal after the first connection mode is abnormal, and is not necessarily detected in the non-sleep state, and in the non-sleep state, the first relay station 12 sends the first scheduling information to the mobile station 13 and the user terminal 14 through the second broadcast mode.

In this embodiment, the dormant state means that the first relay station 12 does not relay data such as air interface data and air interface service, and whether the air interface data is uplink to the scheduling station 11 or the air interface service is downlink to the user terminal 14. The non-sleep state refers to that the first relay station 12 is relaying data such as air interface data or air interface service.

When the first relay station 12 is in different states, the requirements for broadcasting the first scheduling information or the second scheduling information may be different, and in the sleep state, the first relay station 12 sends the first scheduling information or the second scheduling information through the first broadcasting method, and then notifies the vehicle station 13 to enable or disable the second connection method, so as to ensure the effectiveness of subsequent communication.

If the first relay station 12 is in a non-sleep state, for example, the amount of data such as short messages being transmitted and GPS is generally small, the first scheduling information or the second scheduling information may not be transmitted immediately even if the first connection manner is detected to be abnormal or is restored to normal after the abnormality, because the transmitted data amount is small and the transmission can be completed quickly, the first scheduling information or the second scheduling information may be sent after the data transmission is completed, for example, the user terminal 14 is transmitting air interface data with a small data amount to the first relay station 12, even if the first connection mode is abnormal, the first relay station 12 can receive the air interface data soon, and quickly downlink to other user terminals 14, after transmission, the first relay station can be considered to be in a "dormant state", the first scheduling information may be transmitted to the user terminal 14 in the first broadcast manner and the dolly 13 may be notified to enable the second connection manner. For example, when the first relay station 12 relays the air interface service with smaller data sent by the dispatching station 11 to the user terminal 14, even if the first connection mode is detected to be abnormal, the first relay station 12 first transmits the air interface service to the user terminal 14, and then notifies the user terminal 14 and the vehicle platform 13 of sending the first dispatching information. Of course, when the first relay station 12 is in the non-sleep state, if the first connection mode is detected to be abnormal or returns to normal after being abnormal, the first scheduling information may also be sent immediately.

When the first relay station 12 is in the non-sleep state and relays the voice information to the user terminal 14, since the data volume of the voice information is large, the time required for transmission is relatively long, and if the first scheduling information is sent after transmission is completed, transmission of the following data is greatly affected, so that if the first relay station 12 detects that the first connection mode is abnormal, the first relay station 12 sends the first scheduling information to the mobile station 13 and the user terminal 14 in the second broadcast mode. In the process of transferring the voice to the user terminal 14, the first scheduling information is immediately sent to inform the user terminal 14 and the vehicle platform 13, so that the subsequent data transmission is facilitated, and information jam or communication interruption is avoided. If the first relay station 12 is in the non-sleep state and relays the voice information to the user terminal 14, it is detected that the first connection mode is recovered to normal, and the second scheduling information may be sent after the voice information transmission is finished.

In this embodiment, the voice information may come from the dispatching desk 11 or from other user terminals 14, that is, the voice information may be uploaded to the dispatching desk 11 by the other user terminals 14 and relayed to the user terminal 14 by the first relay desk 12, or the voice information may be relayed to the user terminal 14 by the other user terminals 14 directly through the first relay desk 12.

Optionally, the first broadcast mode is beacon (beacon). Specifically, for example, a beacon circuit (not shown) is provided on the first relay station 12, so that the first schedule information or the second schedule information generated by the first relay station 12 can be transmitted through the beacon circuit and can be received by the user terminal 14 and the vehicle station 13. The first scheduling information or the second scheduling information is sent in a beacon mode, and the transmission rate and the transmission stability can be guaranteed under the condition of low power consumption. Of course, the first broadcast mode may also be bluetooth, for example, bluetooth 5.0, bluetooth 4.2, etc., and may also be ZigBee, Z-wave, wifi, etc.

Further, the first relay station 12 includes a first timer, the first timer is preset with a non-broadcast time period, the first timer is started when the first relay station 12 is in a sleep state, the first timer times the non-broadcast time period, and the first relay station 12 does not send or relay the first scheduling information or the second scheduling information.

If the first relay station 12 needs to relay data (air interface data or air interface service, etc.) during the timing process of the first timer, the first timer will stop timing, and restart and count again when the first relay station 12 is in the sleep state again.

Further, the first relay station 12 further includes a second timer, the second timer is preset with a broadcast time period, when the first timer times out of the non-broadcast time period, the first relay station 12 starts the second timer, and when the second timer times out of the broadcast time period, the first relay station 12 sends the first scheduling information or the second scheduling information to the vehicle platform 13 and the user terminal 14 respectively in a beacon manner.

Specifically, when the first relay station 12 is in the sleep state, the first timer and the second timer are alternately timed, that is, the first relay station 12 starts the second timer when the first timer times out of the non-broadcast time period, and the first relay station 12 starts the first timer when the second timer times out of the broadcast time period.

As already mentioned above, for example, there is a time interval between two adjacent detections, so the first scheduling information or the second scheduling information may be generated when the first relay station 12 detects the first connection mode abnormality or returns to normal before the sleep state, or may be generated when the first relay station 12 detects the first connection mode abnormality or returns to normal when in the sleep state. The first timer counts the time in the non-broadcast period, and the first relay station 12 does not transmit the first scheduling information or the second scheduling information. The second timer counts the time within the broadcast time period, and the first relay station 12 transmits the first scheduling information or the second scheduling information to the vehicle station 13 and the user terminal 14 in a beacon manner, respectively. Therefore, the first scheduling information or the second scheduling information is sent by adopting the timing method with interval setting, the system power consumption can be saved, and the service life of equipment can be prolonged.

Optionally, the second broadcast mode is a common broadcast channel (CACH). The common broadcast channel can effectively inform the vehicle platform 13 to start the second connection mode to be in communication connection with the dispatching platform 11 when the first relay platform 12 transfers voice to occupy larger transmission bandwidth, so that the transmission of subsequent data is ensured.

Further, when the first relay station 12 is in the non-sleep state and relays the voice information to the user terminal 14, if the first relay station 12 detects that the first connection mode is abnormal, the first relay station 12 sends the first connection mode abnormal identifier of the first scheduling information to the mobile station 13 through the public broadcast channel to notify the mobile station 13 to enable the second connection mode to be in communication connection with the scheduling station 11.

Specifically, the first relay station 12 can quickly send the first connection mode exception identifier of the first scheduling information through the public broadcast channel, and the vehicle station 13 starts the first connection mode to be in communication connection with the scheduling station 11 after receiving the first connection mode exception identifier, at this time, the communication path of the "first relay station-vehicle station-scheduling station" is already started. Optionally, when the first relay station 12 is in a non-sleep state and relays voice information to the user terminal 14, the first relay station 12 may only send the first connection mode exception identifier through the public broadcast channel, and only send the first connection mode exception identifier to effectively reduce the data volume.

Further, referring to fig. 4, when the first relay station 12 is in the non-sleep state and relays the voice information to the user terminal 14, if the first relay station 12 detects that the first connection mode is abnormal, the first relay station 12 simultaneously sends the first connection mode abnormal identifier of the first scheduling information to the user terminal 14 through the common broadcast channel. That is, the first relay station 12 sends the first connection mode exception identifier of the first scheduling information to the mobile station 13 and the user terminal 14 through the common broadcast channel, and the mobile station 13 starts the second connection mode after receiving the first connection mode exception identifier. For the user terminal 14, the first relay station 12 further embeds the vehicle station ID and the first relay station ID in the first scheduling information into the voice information. And when the user terminal 14 receives the first connection mode abnormal identifier and the embedded voice information, the first scheduling mode is switched, and the user terminal 14 automatically adapts to a communication path of 'scheduling table-vehicle table-transfer table'. Air interface data sent by the user terminal 14 is uploaded to the dispatching desk 11 through the first relay desk 12 via the trolley 13, and air interface services sent by the dispatching desk 11 are received by the user terminal 14 through the trolley 13 via the first relay desk 12.

For example, when transferring the voice information to the user terminal 14, the first relay station 12 encodes and frames the voice information, and embeds the station ID and the first relay station ID data into a partial frame of the voice information, for example, referring to fig. 4, the voice information transmission takes a super frame as a unit, one voice super frame includes 6 voice bursts, the bursts in the super frame are identified by letters a-F, burst a represents the start of the super frame, burst B-F can bear signaling embedded (EMB field + embedded signaling) the user terminal 14 decodes or de-encodes after receiving the voice information, reads the station ID and the first relay station ID, and thus can completely receive the complete first scheduling information.

Certainly, in other embodiments, when the first relay station 12 is in a non-sleep state and relays the voice information to the user terminal 14, if the first relay station 12 detects that the first connection mode is abnormal, the first relay station 12 sends the first connection mode abnormal identifier of the first scheduling information to the mobile station 13 through the public broadcast channel, and the first relay station 12 may embed the first connection mode abnormal identifier, the first relay station ID, and the second relay station ID into the voice information at the same time, and the first scheduling information is sent to the user terminal 14 along with the voice information, and the user terminal 14 reads all the first scheduling information at one time after receiving the voice information, so as to switch to the first scheduling mode.

Optionally, when the first relay station 12 is in the non-sleep state and relays the voice information to the user terminal 14, if the first relay station 12 returns to normal after detecting that the first connection mode is abnormal, similar to the above processing, the first connection mode normal identifier may be broadcast through a common channel and sent to the user terminal 14 and the train station 13, and the first relay station ID and the train station ID are embedded into the voice information and sent to the user terminal 14, or the first connection mode abnormal identifier, the first relay station ID and the second relay station ID are simultaneously embedded into the voice information and sent to the user terminal 14, and the train station 13 is notified to disable the second connection mode and the user terminal 14 is notified to switch to the second scheduling mode. In other embodiments, of course, after the voice message is relayed, when the first relay station 12 is in the dormant state, the second scheduling information may be sent in the beacon mode, so as to notify the mobile station 13 to disable the second connection mode, and notify the user terminal 14 to switch to the second scheduling mode.

Through the above manner, the first relay station 12 is relaying voice to the user terminal, even if the first connection mode is detected to be abnormal, the second connection mode can be quickly started by the mobile station 13, and the user terminal 14 is quickly adapted to the first scheduling mode, so that the whole system can be quickly adjusted to normally and effectively send data, and the problems of data blocking and the like caused by system adjustment delay are avoided.

Referring to fig. 1 and fig. 2, the first connection mode may be a network connection, and specifically may be an IP network connection, such as a wireless network connection or a wired network connection. The dispatching desk 11 is further configured to send a heartbeat packet to the first relay desk 12, and the first relay desk 12 detects whether the first connection mode is abnormal by detecting whether the heartbeat packet can be received. Of course, the heartbeat packets are sent between the first relay station 12 and the dispatching station 11, for example, at intervals, for example, many times per minute. When the first connection mode is normal, the network connection mode has stronger transmission capability and wider coverage range, and is favorable for flexibly arranging the position of the first middle station. In this embodiment, if the first relay station 12 does not detect the heartbeat packet, it is determined that the first connection method is abnormal. If the first relay station 12 detects the heartbeat packet again, it is determined that the first connection mode is recovered to be normal.

Referring to fig. 1 and 2, the second connection mode may be a wired connection. In the present embodiment, the vehicle mount 13 and the dispatch station 11 are wired via a USB or universal serial data bus (uarr).

Referring to fig. 1 to 3, the first relay station 12 is optionally communicatively connected to the vehicle base 13 through an air interface (air interface) or a general purpose I/O interface (e.g., GPIO pin). And informing the trolley 13 to enable or disable the second connection mode through the level change of the GPIO pin. The first relay station 12 shown in fig. 1-2 is communicatively connected to the vehicle base 13 through an air interface (air interface), and the first relay station 12 shown in fig. 3 is communicatively connected to the vehicle base 13 through a general purpose I/O interface (e.g., GPIO pin).

Referring to fig. 1 to 3, further, the scheduling system further includes a plurality of second relay stations 15, the plurality of second relay stations 15 are respectively in communication connection with the first relay station 12, the air interface data acquired by the plurality of second relay stations 15 is uploaded to the scheduling station 11 through the first relay station 12, and the air interface service sent by the scheduling station 11 is relayed to the plurality of second relay stations 15 through the first relay station 12. That is, in the present embodiment, the second relay station 15 is not directly connected to the dispatching station 11 and the vehicle station 13 in communication, but is connected to the dispatching station 11 and the vehicle station 13 in communication through the first relay station 12. Of course, in another embodiment, the second relay station 15 is disposed in parallel with the first relay station 12, and is connected in parallel to the dispatching desk 11 and the vehicle platform 13 in communication.

Specifically, the first relay station 12 and the second relay station 15 may be connected through an IP network, wherein the first relay station 12 is communicatively connected with the dispatching station 11. In this embodiment, the first relay station 12 may correspond to a plurality of user terminals 14, and each of the second relay stations 15 may correspond to a plurality of user terminals 14.

In summary, in order to ensure the stability of the entire communication system and avoid that the entire communication system is paralyzed due to a failure of a single connection mode and effective communication between each device and a node cannot be performed, in the scheduling system provided in this embodiment, whether the first connection mode is abnormal is detected by the first relay station 12, and in case of the abnormality, first scheduling information is generated and at least sent to the vehicle station 13, and the vehicle station 13 is notified to start the second connection mode to perform communication connection with the scheduling station 11, so that data is transmitted through a communication path of "first relay station-vehicle station-scheduling station", thereby solving the problem that communication cannot be ensured due to the single connection mode in the prior art, and ensuring the stability of data transmission and work of the entire communication system.

S102: the first relay station detects whether the first connection mode is abnormal.

Specifically, there are various detection manners, for example, when the first connection manner is a network connection, whether the first connection manner is normal or not may be detected by receiving and sending a heartbeat packet. For example, the first relay station detects whether the first connection method is abnormal by detecting whether the heartbeat packet transmitted from the dispatch station to the first relay station can be received. Of course, the first relay station and the dispatching station may send heartbeat packets to each other, for example, at a certain time interval, so as to receive the heartbeat packet of the other party.

S103: the first relay station detects that the first connection mode is abnormal.

If the first relay station cannot detect the heartbeat packet, it can be determined that the first connection mode is abnormal. And if the first relay station detects the heartbeat packet again, the first connection mode can be judged to be recovered to be normal.

And the air interface data sent to the dispatching desk by the user terminal is finally uploaded to the dispatching desk through the first transfer desk and the vehicle platform.

S108: and the first transfer platform returns to normal after detecting that the first connection mode is abnormal.

The recovery from the abnormality means that after the first connection mode is abnormal, the first relay station continues to detect whether the first connection mode is abnormal, so that the first connection mode is detected to be recovered from the normal state.

S109: the first relay station generates second scheduling information.

In this embodiment, the second scheduling information includes a first relay station ID, a vehicle station ID, and a first connection mode normal flag.

In this embodiment, S111 and S112 may also be regarded as the same step.

S113: the user terminal responds to the second scheduling information.

And the user terminal is switched to a second scheduling mode to adapt to a communication path of 'first relay station-scheduling station'. The format, size, description information, etc. of the information sent by the user terminal may need to be changed to adapt to the communication path, so as to ensure the matching and stability of the transmission.

The air interface data sent by the user terminal to the dispatching desk is directly uploaded to the dispatching desk through the first relay desk, and the air interface service sent by the dispatching desk is directly sent to the first relay desk through the first connection mode.

This embodiment is a further extension of the second embodiment of the adaptive scheduling method of the present application, and therefore, the same steps as those in the second embodiment of the adaptive scheduling method of the present application are not described herein again. The embodiment comprises the following steps:

s301: and in a default state, the first relay station is in communication connection with the dispatching desk in a first connection mode, so that data transmission of air interface data, air interface services and the like is realized.

S302: the first relay station detects whether the first connection mode is abnormal.

In this embodiment, the step of detecting whether the first connection mode is abnormal or not by the first relay station may be regarded as a continuous detection process, for example, detection is continuously performed at certain time intervals, for example, how many times per minute or once every 30 seconds, etc., and the abnormality may not be detected in the sleep state, but may be detected in the non-sleep state.

S303: the first relay station is in a sleep state.

For the third embodiment of the adaptive scheduling method, reference may be made to the description in the embodiment of the adaptive scheduling system and the description in the second embodiment of the adaptive scheduling method, which are not described herein too much.

Referring to fig. 8-9, a fourth embodiment of the adaptive scheduling method of the present application is based on the third embodiment of the adaptive scheduling method of the present application, where the first intermediate station starts the first timer and the second timer in the sleep state to send the first scheduling information and the second scheduling information to the mobile station and the user terminal through the beacon. This embodiment is a further extension of the third embodiment of the adaptive scheduling method of the present application, and therefore, the same steps as those in the third embodiment of the adaptive scheduling method of the present application are not described herein again. The embodiment comprises the following steps:

referring to fig. 8, in the sleep state of the first relay station of the present embodiment, the content of the relevant flow when the first connection mode is detected to be abnormal:

s401: and in a default state, the first relay station is in communication connection with the dispatching desk in a first connection mode, so that data transmission of air interface data, air interface services and the like is realized.

S402: the first relay station detects whether the first connection mode is abnormal.

In this embodiment, the step of detecting whether the first connection mode is abnormal or not by the first relay station may be a continuous detection process, for example, the detection is continuously performed at certain time intervals, for example, multiple times per minute, so that the detection is not necessarily performed in the broadcast time period, that is, the detection step may be a process that goes through the sleep state and the non-sleep state.

S403: the first relay station is in a sleep state.

S404: the first relay station starts a first timer.

S404 a: the first timer times a non-broadcast period.

S405: the first relay station detects that the first connection mode is abnormal.

S406: the first relay station generates first scheduling information.

The first relay station detects whether the first connection mode is abnormal or not, that is, it is not necessarily within the non-broadcast time period to detect that the first connection mode is abnormal, and thus the first relay station does not necessarily generate the first scheduling information within the non-broadcast time period.

S407: the first relay station does not transmit the first scheduling information.

That is, the first timer counts the non-broadcast period, and the first relay station does not transmit the first scheduling information even if the first connection scheme abnormality is detected.

s401': and in a default state, the first relay station is in communication connection with the dispatching desk in a first connection mode, so that data transmission of air interface data, air interface services and the like is realized.

S402': the first relay station detects whether the first connection mode is abnormal.

S411': the vehicle station responds to the second scheduling information.

S411 a': and the vehicle platform forbids the second connection mode to be in communication connection with the dispatching desk.

S412': the user terminal responds to the second scheduling information.

The first relay station does not send the first scheduling information or the second scheduling information when the first timer times in a non-broadcast time period, and the first relay station only sends the first scheduling information or the second scheduling information when the second timer times in a broadcast time period. The first scheduling information may be generated in a non-broadcast period or may be generated in a broadcast period, but the transmission is transmitted in the broadcast period.

In this embodiment, if the first relay station needs to relay data (air interface data or air interface service, etc.) during the timing process of the first timer, the first timer stops timing, and restarts and times again when waiting for the first relay station to be in the sleep state again.

Specifically, when the first relay station is in the sleep state, the first timer and the second timer are alternately timed, that is, when the first timer times out of the broadcasting time period, the first relay station starts the second timer, and when the second timer times out of the non-broadcasting time period, the first relay station starts the first timer. The broadcast periods alternate with the non-broadcast periods. Therefore, the first scheduling information or the second scheduling information is sent by adopting the timing method with interval setting, the system power consumption can be saved, and the service life of equipment can be prolonged.

Of course, when the first relay station is in the sleep state, the second timer is started first, and the first scheduling information or the second scheduling information may be sent within the broadcast time period. And starting the first timer when the second timer times out of the broadcasting time period, and not sending the first scheduling information and the second scheduling information when the second timer times out of the broadcasting time period.

For the fourth embodiment of the adaptive scheduling method, reference may be made to the description in the embodiment of the adaptive scheduling system and the description in the first to third embodiments of the adaptive scheduling method, which will not be described herein too much.

Referring to fig. 10, a fifth embodiment of the adaptive scheduling method of the present application is based on the second embodiment of the adaptive scheduling method of the present application, and the first intermediate station sends the first scheduling information or the second scheduling information to the mobile station and the ue in the non-sleep state through the second broadcast method.

S502: the first relay station detects whether the first connection mode is abnormal.

S503: the first relay station is in a non-dormant state and relays voice information to the user terminal.

Because the amount of data with much voice information is large, the time required for transmission is relatively long, and if the first scheduling information is sent after transmission is finished, the transmission of the following data is greatly influenced.

S504: the first relay station detects that the first connection mode is abnormal.

S505: the first relay station generates first scheduling information.

S506: and the first relay station sends the first scheduling information to the vehicle station and the user terminal in a second broadcasting mode.

In the process of transferring the voice to the user terminal by the first relay station, if the first relay station detects that the first connection mode is abnormal, the first relay station sends first scheduling information to the vehicle station and the user terminal in a second broadcast mode. In the process of transferring the voice to the user, the first scheduling information is immediately sent to inform the user terminal and the vehicle platform, so that the transmission of subsequent data is facilitated, and information blockage or communication interruption is avoided. In this embodiment, the second broadcast mode is, for example, a common broadcast channel, a common assignment channel, a broadcast control channel, etc.

S513 a: and the vehicle platform forbids the second connection mode to be in communication connection with the dispatching desk.

S514: the user terminal responds to the first scheduling information.

S514 a: the user terminal switches to the second scheduling mode.

In this embodiment, if the first relay station detects that the first connection mode is abnormal and then returns to normal when transferring the voice information to the user terminal, the second relay station may also send the second scheduling information when waiting for the first relay station to be in a dormant state after transferring the voice information. At this time, the vehicle platform responds to the second scheduling information and disables the second connection mode. And the user terminal responds to the second scheduling information and switches to the second scheduling mode.

For the fifth embodiment of the adaptive scheduling method, reference may be made to the description in the embodiment of the adaptive scheduling system and the description in the first to fourth embodiments of the adaptive scheduling method, which will not be described herein too much.

Referring to fig. 11, a sixth embodiment of the adaptive scheduling method of the present application is based on the fifth embodiment of the adaptive scheduling method of the present application, where the first intermediate station transmits the voice information in the non-sleep state, transmits the first scheduling information or the second scheduling information to the mobile station in the second broadcast mode, and embeds the scheduling information into the voice information to transmit the voice information to the user terminal. This embodiment is a further extension of the fifth embodiment of the adaptive scheduling method of the present application, and therefore, the steps that are the same as those in the fifth embodiment of the adaptive scheduling method of the present application are not described herein again. The embodiment comprises the following steps:
