Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all 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.

Referring to fig. 1, fig. 1 is a framework diagram of a networking architecture provided in an embodiment of the present application, where networking may include: base station controller, base station 1, base station 2, terminal 1, terminal 2, terminal 3 and terminal 4. Wherein, base station 1 and base station 2 access base station controller, terminal 1 and terminal 2 access base station 1, terminal 3 and terminal 4 access base station 2. Each base station in fig. 1 may be an RFID base station, and each terminal may be an RFID terminal.

In the related art, when the base station controller needs to issue a message (i.e., a to-be-processed message) to the terminal 1, the base station controller may broadcast the to-be-processed message to the base stations 1 and 2. The base station 1 can send the message to be processed to the terminal 1 and the terminal 2 in a broadcast manner, and the base station 2 can send the message to be processed to the terminal 3 and the terminal 4 in a broadcast manner, so that the terminal 1 can receive the message to be processed.

In the above processing process, the base station controller and each base station all send messages in a broadcast manner, and the base station controller only needs to send messages to the terminal 1, that is, more useless messages exist in networking, which further affects the performance of the network.

In order to solve the above problem, an embodiment of the present application provides a message processing method, where a base station controller may obtain a to-be-processed message that needs to be sent to a terminal 1, and determine a base station (that is, a base station 1) to which the terminal 1 is currently accessed according to a received heartbeat message sent by the terminal 1, and then the base station controller may send the to-be-processed message to the base station 1. After the base station 1 receives the message to be processed, the base station 1 may send the message to be processed to the terminal 1.

Based on the above processing, the base station controller only sends the message to be processed to the base station 1 currently accessed by the terminal 1, but not sends the message to be processed to all the base stations, and then only the base station 1 sends the message to be processed to the accessed terminal, so that in sum, useless messages in the networking can be reduced, and the influence on the network performance is reduced.

Referring to fig. 2, fig. 2 is a flowchart of a message processing method provided in an embodiment of the present application, where the method may be applied to a base station controller in an RFID network, and the method may include the following steps:

s201: and acquiring a message to be processed which needs to be issued to the terminal.

The terminal (which may be referred to as a target terminal) may be an electronic device supporting RFID, for example, an RFID-supported sports bracelet, an RFID-supported electronic watch, or the like, and the target terminal may access a base station managed by a base station controller.

In the embodiment of the application, when a user needs to issue a message (i.e., a to-be-processed message) to a target terminal, the user may input the to-be-processed message to a base station controller through an input device of the base station controller, and accordingly, the base station controller may obtain the to-be-processed message that needs to be issued to the target terminal.

In addition, when the user inputs the message to be processed to the base station controller, the user can also input the identification of the target terminal to the base station controller. The base station controller can obtain the identification of the target terminal and determine the target terminal for receiving the message to be processed according to the identification of the target terminal. The identifier of the target terminal may be a Media Access Control (MAC) address of the target terminal or other identifiers used for distinguishing the target terminal.

S202: and determining a first base station currently accessed by the terminal according to the received heartbeat message sent by the terminal.

In the RFID network, a target terminal may periodically send a heartbeat packet to a base station controller, where the heartbeat packet may carry physical location information of the target terminal. Correspondingly, the base station controller can determine the current physical position of the target terminal according to the heartbeat message sent by the target terminal.

In the embodiment of the present application, the base station controller may determine, according to the heartbeat message sent by the target terminal, a base station (denoted as a first base station in this embodiment) to which the target terminal is currently accessed, where the first base station is a base station that currently forwards the heartbeat message of the target terminal.

In one implementation, if the base station controller has received the heartbeat message sent by the target terminal before the base station controller obtains the message to be processed, the base station controller may determine the first base station according to the received heartbeat message.

In another mode, after the base station controller obtains the message to be processed, if the base station controller receives a heartbeat message sent by the target terminal, the base station controller may determine the first base station according to the currently received heartbeat message.

S203: and sending the message to be processed to the first base station so that the first base station sends the message to be processed to the terminal.

In the embodiment of the present application, after determining the first base station to which the target terminal is currently accessed, the base station controller may send a message to be processed to the first base station. After the first base station receives the message to be processed, the first base station may send the message to be processed to the target terminal. The first base station may broadcast and send the pending message, and since the target terminal is currently accessed to the first base station, the target terminal may receive the pending message broadcast and sent by the first base station.

According to the mechanism of receiving and sending messages by the RFID chip, the target terminal configured with the RFID chip sends and receives messages alternately, and cannot receive and send messages simultaneously, that is, the target terminal can receive messages sent by the base station controller only within a preset time after the target terminal sends heartbeat messages to the base station controller, wherein the preset time is usually microsecond level. After the target terminal sends the heartbeat message to the base station controller, when the preset time length is exceeded, the target terminal enters a message sending state at the moment, only the message can be sent outwards at the moment, so that the message sent by the base station controller cannot be received, and the target terminal can not receive the message sent by the base station controller until the preset time length after the target terminal sends the heartbeat message to the base station controller again.

Therefore, the base station controller can send the message to be processed to the target terminal when receiving the heartbeat message sent by the target terminal, so as to improve the success rate of receiving the message to be processed by the target terminal.

In one implementation, when the base station controller obtains the message to be processed, the base station controller may temporarily not send the message to be processed. After the base station controller obtains the message to be processed, when the base station controller receives the heartbeat message sent by the target terminal, the base station controller may use the base station that forwards the heartbeat message this time as a first base station to which the target terminal is currently accessed, and then the base station controller may send the message to be processed to the first base station. The first base station can send the message to be processed to the target terminal, so that the target terminal can receive the message to be processed within a preset time length after the heartbeat message is sent to the base station controller.

Therefore, the base station controller can trigger to send the message to be processed to the target terminal when receiving the heartbeat message sent by the target terminal, so that the situation that the target terminal cannot obtain the message to be processed can be avoided to a certain extent, and the success rate of obtaining the message to be processed by the target terminal is improved.

Optionally, a message forwarding table may also be maintained in the base station controller, and the base station controller may determine whether to issue the message to be processed according to the message forwarding table, referring to fig. 3, after S201, the method may further include the following steps:

s204: and judging whether a message forwarding table entry of the terminal exists in the message forwarding table, and if so, executing S202.

The base station controller may generate a message forwarding table entry of each terminal according to the heartbeat message sent by each terminal, where the message forwarding table entry may include: the identifier of the terminal and the identifier of the base station to which the terminal accesses, for example, the message forwarding table entry generated by the base station controller may be referred to in table (1).

Watch (1)

Identification of terminal	Identification of base station
		Terminal 1	Base station 1
Terminal 3	Base station 2

The identifier of the base station may be a MAC address of the base station or other identifiers used for distinguishing different base stations. When the base station controller receives the heartbeat message sent by the terminal 1 through the base station 1, the base station controller can determine that the terminal 1 is currently accessed to the base station 1; when the base station controller receives the heartbeat message sent by the terminal 3 through the base station 2, the base station controller may determine that the terminal 3 is currently accessed to the base station 2, and may further obtain the message forwarding table entry shown in the table (1).

In addition, as the terminal moves, the physical location of the terminal may change, and the base station to which the terminal accesses may also change, so that the base station controller may update the message forwarding table entry of the terminal according to the latest heartbeat message sent by the terminal.

In order to reduce the useless message forwarding table entry in the base station controller, the message forwarding table can also record a time stamp and an aging duration, and the base station controller can update the message forwarding table according to the time stamp and the aging duration.

For a message forwarding table entry of a certain terminal, a timestamp in the message forwarding table entry is used to indicate a time when the base station controller receives a latest heartbeat message sent by the terminal, and the base station controller may update the timestamp in the message forwarding table entry each time the base station controller receives the heartbeat message sent by the terminal.

With the movement of the terminal, the terminal may not be in the network service range managed by the base station controller, and the terminal may not be able to send the heartbeat message to the base station controller, so that when the time length from the last time when the heartbeat message received by the terminal reaches the aging time length, if the base station controller does not receive the heartbeat message sent by the terminal again, the base station controller may delete the message forwarding table entry of the terminal.

In an implementation manner, on the basis of the embodiment corresponding to the table (1), the message forwarding table entry may further include: the time stamp and the aging duration, for example, can be seen in table (2).

Watch (2)

Identification of terminal	Identification of base station	Time stamp	At the time of agingIs long and long
				Terminal 1	Base station 1	T1	S1
Terminal 3	Base station 2	T2	S2

For table (2), the time that the base station controller last receives the heartbeat message sent by the terminal 1 is T1, timing is started from T1, and when the timing duration reaches the aging duration S1, if the base station controller does not receive the heartbeat message sent by the terminal 1 again, that is, the terminal 1 may not be currently in the network service range managed by the base station controller, the base station controller may delete the message forwarding table entry of the terminal 1.

Therefore, after the base station controller obtains the message to be processed which needs to be issued to the target terminal, the base station controller can judge whether the message forwarding table item of the target terminal exists in the message forwarding table, and carry out subsequent processing according to the judgment result.

In the embodiment of the application, if the base station controller determines that the message forwarding table entry of the target terminal exists in the message forwarding table, the base station controller may determine a first base station to which the target terminal is currently accessed when receiving a heartbeat message sent by the target terminal, and send the message to be processed to the first base station, and correspondingly, the first base station may send the message to be processed to the target terminal.

In this step, the base station controller determines that the message forwarding table entry of the target terminal exists in the message forwarding table, that is, the target terminal is still in the network service range managed by the base station controller currently, so that the base station controller can directly send the message to be processed to the first base station.

In addition, if the base station controller determines that the message forwarding table entry of the target terminal does not exist in the message forwarding table, that is, the target terminal is not currently within the network service range managed by the base station controller, at this time, the base station controller cannot issue the message to be processed to the target terminal.

Correspondingly, referring to fig. 3, if it is determined in step S204 that the message forwarding table entry of the terminal does not exist in the message forwarding table, the method may further include the following steps:

s205: and confirming that the message to be processed cannot be issued to the terminal currently.

In one implementation, when the base station controller determines that the message forwarding table entry of the target terminal does not exist in the message forwarding table, the base station controller may determine that the message to be processed cannot be currently issued to the target terminal. For example, the base station controller may display a message "pending message cannot be issued to the target terminal at present" in the display section.

Optionally, in order to improve the success rate of the target terminal receiving the message to be processed, the message forwarding table entry of the target terminal may further include an identifier of the message to be processed and a delivery state of the message to be processed, where the delivery state of the message to be processed is not delivered or has been delivered. After S203, the method may further include the steps of:

step one, setting the issuing state of the message to be processed as issued.

In an implementation manner, on the basis of the embodiments corresponding to the table (1) and/or the table (2), the message forwarding table entry may further include: for example, see table (3), the identifier of the message to be processed and the delivery status of the message to be processed.

Watch (3)

Identification of terminal	Identification of base station	Time stamp	Length of aging	Pending messages	Issuing status
						Terminal 1	Base station 1	T1	S1	Message to be processed 1	Is not sent down
Terminal 3	Base station 2	T2	S2	Pending message 2	Has already sent down

For the table (3), when the base station controller obtains the message 1 to be processed that needs to be sent to the terminal 1, the base station controller may record the identifier of the message 1 to be processed in the message forwarding table entry of the terminal 1.

When the base station controller obtains the message 2 to be processed that needs to be sent to the terminal 3, the base station controller may record the identifier of the message 2 to be processed in the message forwarding table entry of the terminal 3.

In addition, when the base station controller obtains the message 1 to be processed that needs to be delivered to the terminal 1, the base station controller may determine that the delivery status corresponding to both the terminal 1 and the message 1 to be processed is "not delivered". When the base station controller sends the message 1 to be processed to the base station 1, the base station controller may modify the delivery status corresponding to both the terminal 1 and the message 1 to be processed into "delivered".

Therefore, after the base station controller sends the message to be processed to the first base station, the base station controller may set the down status in the message forwarding table entry of the target terminal to "down".

And step two, starting a timer corresponding to the message to be processed.

The timer may have a preset timing length. After the timer is started, when the timing length is exceeded, the timer is timed out, and the timing length can be set by a technician according to experience. The base station controller can time the waiting process of the issuing result of the message to be processed by the timer.

In the embodiment of the present application, after the base station controller sends the pending message to the first base station, the base station controller may further start a timer corresponding to the pending message.

And step three, if the heartbeat message sent by the terminal is received again before the timer is overtime, judging whether the second base station and the first base station which are accessed by the terminal currently are the same base station or not.

In the embodiment of the application, when a first base station broadcasts and sends a message to be processed, the physical location of a target terminal may change along with the movement of the target terminal, and the target terminal may access another base station. Correspondingly, the target terminal can also send the heartbeat message to the base station controller through another base station.

Based on this, after the base station controller starts the timer corresponding to the message to be processed, if the base station controller receives the heartbeat message sent by the target terminal again before the timer expires, the base station controller may determine whether the base station (denoted as the second base station in this embodiment) currently accessed by the target terminal and the first base station are the same base station.

And step four, if the second base station is not the same as the first base station, deleting the timer and sending the message to be processed to the second base station so that the second base station sends the message to be processed to the terminal.

In the embodiment of the present application, when the base station controller determines that the second base station is not the same as the first base station, the base station controller may delete the current timer and send the message to be processed to the second base station. Accordingly, the second base station may send the pending message to the target terminal. After the base station controller sends the message to be processed to the second base station, the base station controller may also reset the timer corresponding to the message to be processed, so as to retime the waiting process of the result of the transmission of the message to be processed.

In this step, when the base station controller determines that the second base station is not the same as the first base station, the base station controller may determine that the target terminal moves into a network service range of another base station, that is, the target terminal may not receive the message to be processed sent by the first base station, and therefore, the base station controller may send the message to be processed to the base station (i.e., the second base station) to which the target terminal is currently accessed again. The second base station may forward the message to be processed to the target terminal, so as to improve the success rate of receiving the message to be processed by the target terminal.

In addition, when the first base station broadcasts and sends the message to be processed, the target terminal may not receive the message to be processed sent by the first base station along with the movement of the target terminal, and meanwhile, the target terminal may not send the heartbeat message to the base station controller.

Therefore, after the base station controller starts the timer, the base station controller may further determine whether the heartbeat packet sent by the target terminal is received again, and perform corresponding processing, where the method may further include the following steps:

if the timer is overtime, the heartbeat message sent by the terminal is not received again, and the identifier of the message to be processed is deleted from the message forwarding table entry of the terminal.

In the embodiment of the present application, after the base station controller sends the to-be-processed message to the base station to which the target terminal is currently accessed, and starts the timer, if the timer has timed out, the base station controller still does not receive the heartbeat message sent by the target terminal again, that is, the base station controller does not receive the heartbeat message sent by the target terminal again from the start of the timer corresponding to the to-be-processed message to the time period when the timer is timed out, and then the base station controller may delete the identifier of the to-be-processed message from the message forwarding table entry of the target terminal.

In this step, when the base station sends the message to be processed to the target terminal, since the target terminal moves, the target terminal may not receive the message to be processed, and may not send the heartbeat message to the base station controller, therefore, if the timer has timed out, the base station controller still does not receive the heartbeat message sent by the target terminal again, the base station controller may determine that the message to be processed fails to be issued, and delete the identifier of the message to be processed from the message forwarding table entry of the target terminal.

Optionally, the base station controller may further determine, according to the confirmation message sent by the target terminal, whether the target terminal successfully receives the message to be processed, and after the base station controller starts the timer, the method may further include the following steps:

step one, judging whether a confirmation message sent by a terminal is received before a timer is overtime.

In the embodiment of the present application, after the base station sends the message to be processed to the target terminal, if the target terminal receives the message to be processed, the target terminal may send an ACK (acknowledgement) message to the base station controller through the base station. Therefore, the base station controller can judge whether the confirmation message sent by the target terminal is received before the timer is overtime, so as to carry out subsequent processing according to the judgment result.

Step two: and if the timer is overtime and the confirmation message is not received, deleting the identifier of the message to be processed from the message forwarding table entry of the terminal.

In the embodiment of the present application, if the timer has timed out and the base station controller has not received the acknowledgement message sent by the target terminal, the base station controller may delete the identifier of the message to be processed from the message forwarding table entry of the target terminal.

In one implementation, if the timer has timed out and the base station controller does not receive the acknowledgement message, the base station controller may determine that the target terminal does not receive the message to be processed, that is, the base station controller determines that the transmission of the message to be processed to the target terminal fails, and further, the base station controller may delete the identifier of the message to be processed from the message forwarding table entry of the target terminal.

In addition, when the base station controller confirms that the message to be processed is failed to be sent to the target terminal, the base station controller can also record the failure of sending the message to be processed to the target terminal in a message forwarding table entry corresponding to the target terminal and the message to be processed.

Alternatively, when the base station controller confirms that the delivery of the pending message to the target terminal has failed, the base station controller may display a message of "failure to deliver the pending message to the target terminal" in the display section.

Step three: if an acknowledgement message is received before the timer times out, the timer is deleted.

In the embodiment of the present application, if the base station controller receives the confirmation message sent by the target terminal before the timer expires, the base station controller may delete the timer corresponding to the message to be processed.

In one implementation, if the base station controller receives the acknowledgment message before the timer expires, the base station controller may determine that the target terminal receives the message to be processed, that is, the base station controller acknowledges that the message to be processed is successfully delivered to the target terminal, and further, the base station controller may delete the timer corresponding to the message to be processed.

In addition, when the base station controller confirms that the message to be processed is successfully sent to the target terminal, the base station controller can also record that the message to be processed is successfully sent to the target terminal in a message forwarding table entry corresponding to the target terminal and the message to be processed.

Alternatively, when the base station controller confirms that the transmission of the message to be processed to the target terminal is successful, the base station controller may display a message of "successful transmission of the message to be processed to the target terminal" in the display unit.

Referring to fig. 4, fig. 4 is a flowchart of a message processing method provided in an embodiment of the present application, where the method may be applied to a terminal (i.e., a target terminal) in an RFID network, and the method may include the following steps:

s401: and receiving a message to be processed sent by a base station which is accessed by the terminal currently.

The message to be processed is a message sent to the base station by the base station controller accessed by the base station under the condition that the base station is determined to be the base station currently accessed by the target terminal according to the heartbeat message sent by the target terminal.

The target terminal may be an RFID-enabled electronic device, such as an RFID-enabled sports bracelet, an RFID-enabled electronic watch, or the like.

In the embodiment of the application, the base station controller may obtain a message to be processed, which needs to be issued to the target terminal, and determine a base station to which the target terminal is currently accessed according to the heartbeat message sent by the target terminal, and then the base station controller may send the message to be processed to the base station. After the base station receives the message to be processed, the base station may send the message to be processed to the target terminal, and correspondingly, the target terminal may receive the message to be processed sent by the base station.

The processing steps of the base station controller can be referred to the detailed description of the above embodiments.

S402: an acknowledgement message is sent to the base station to cause the base station to forward the acknowledgement message to the base station controller.

The acknowledgement message is used to notify the target terminal of the base station controller that the message to be processed is received, and the acknowledgement message may be an ACK message.

In the embodiment of the present application, after the target terminal receives the message to be processed sent by the base station, the target terminal may send an acknowledgement message to the base station, and correspondingly, the base station may forward the acknowledgement message to the base station controller. After receiving the confirmation message, the base station controller can confirm that the target terminal receives the message to be processed.

Therefore, based on the method of the embodiment of the application, the base station controller only sends the message to be processed to the base station to which the target terminal is currently accessed, and compared with the prior art that the base station controller sends the message to be processed in a broadcasting mode, the method can reduce useless messages in the networking and reduce the influence on the network performance.

Referring to fig. 5, fig. 5 is a flowchart of an example of a message processing method provided in this embodiment, where the method may be applied to the base station controller in fig. 1, and the method may include the following steps:

s501: when a message to be processed which needs to be sent to the terminal 1 is acquired, whether a message forwarding table entry of the terminal 1 exists in a message forwarding table is judged, if not, S502 is executed, and if so, S503 is executed.

The message forwarding table comprises an identifier of the terminal, an identifier of a base station accessed by the terminal, an identifier of a message to be processed, a sending state of the message to be processed, a timestamp and an aging time length.

S502: and confirming that the pending message cannot be issued to the terminal 1 currently.

S503: when receiving a heartbeat message sent by the terminal 1, determining a first base station currently accessed by the terminal 1.

S504: and sending the message to be processed to the first base station, so that the first base station sends the message to be processed to the terminal 1.

S505: setting the issuing state of the message to be processed as issued, and starting a timer corresponding to the message to be processed.

S506: and judging whether the heartbeat message sent by the terminal 1 is received again before the timer is overtime, if not, executing S507, and if so, executing S508.

S507: confirming that the message to be processed is failed to be sent to the terminal 1, and deleting the identifier of the message to be processed from the message forwarding table entry of the terminal 1.

S508: whether the second base station currently accessed by the terminal 1 is the same base station as the first base station is judged, if not, S509 is executed, and if so, S5010 is executed.

S509: deleting the timer, sending the message to be processed to the second base station so that the second base station sends the message to be processed to the terminal 1, resetting the timer corresponding to the message to be processed, and updating the timestamp in the message forwarding table entry of the terminal 1.

S5010: and confirming that the message to be processed is successfully sent to the terminal 1, and updating the timestamp in the message forwarding table entry of the terminal 1.

Referring to fig. 6, fig. 6 is a flowchart of an example of a message processing method provided in an embodiment of the present application, where the method may be applied to the base station controller in fig. 1, and the method may include the following steps:

s601: when a message to be processed, which needs to be sent to the terminal 1, is acquired, it is determined whether a message forwarding table entry of the terminal 1 exists in the message forwarding table, if not, S602 is executed, and if so, S603 is executed.

The message forwarding table comprises an identifier of the terminal, an identifier of a base station accessed by the terminal, an identifier of a message to be processed, a sending state of the message to be processed, a timestamp and aging duration.

S602: it is confirmed that the message to be processed cannot be currently issued to the terminal 1.

S603: when receiving a heartbeat message sent by the terminal 1, determining a first base station currently accessed by the terminal 1.

S604: and sending the message to be processed to the first base station, so that the first base station sends the message to be processed to the terminal 1.

S605: setting the issuing state of the message to be processed as issued, and starting a timer corresponding to the message to be processed.

S606: it is determined whether an acknowledgement message sent by the terminal 1 is received before the timer expires, if yes, S607 is executed, and if no, S608 is executed.

S607: confirming the successful sending of the message to be processed to the terminal 1 and deleting the timer.

S608: confirming that the message to be processed is failed to be sent to the terminal 1, and deleting the identifier of the message to be processed from the message forwarding table entry of the terminal 1.

It can be seen that the base station controller may obtain a message to be processed that needs to be issued to the terminal 1, determine a base station to which the terminal 1 is currently accessed according to the heartbeat message sent by the terminal 1, and send the message to be processed to the base station, where the base station may send the message to be processed to the terminal 1. Based on the above processing, the base station controller only sends the message to be processed to the base station to which the terminal 1 is currently accessed, and compared with the prior art in which the base station controller sends the message to be processed by broadcasting, the method can reduce useless messages in the networking and reduce the influence on the network performance.
