The above and the technical effects of the invention can be easily understood from the following detailed description of the embodiments and the accompanying drawings.

1 is a block diagram of an embodiment of a network device 100 of the present invention. In this embodiment, the network device 100 is connected between the user equipment 400 and the Internet 500 to provide network services to the user equipment 400. The network device 100 is any network device that can be connected to the Internet 500, such as a digital subscriber line/cable modem (XDSL/Cable Modem), a gateway (Gateway), a router (Router), etc. . The user device 400 is any electronic device that requires a network connection service, such as a personal computer (PC), a notebook computer (Notebook Computer), a personal digital assistant (PDA), and the like.

The network device 100 can record the networking information of the user equipment 400. In this embodiment, the networking information of the user equipment 400 includes the network connection time of the user equipment 400 or the network connection traffic of the user equipment 400.

In an embodiment of the present invention, the network device 100 includes a flash memory 200, a random access memory (300), a network access service module 110, a networked information recording module 120, and Network monitoring module 130. The network service module 110 is configured to provide a network service for the user equipment 400.

The network information recording module 120 can reliably record the network information of the user equipment 400 by using the flash memory 200. In an embodiment of the invention, the networked information recording module 120 includes a setting module 121, a copying module 122, a recording module 123, and a writing module 124.

The random access memory 300 is used to store data currently running. The flash memory 200 is used to store bits that characterize networking information. In the present embodiment, the flash memory 200 divides a fixed-size block, such as 64 Kbits, from its storage space for storing bits representing the networking information.

The setting module 121 is configured to initialize a bit characterization of the networking information in the flash memory 200 to a first value, and set a bit of the characterization of the network information in the flash memory 200 during the networking of the user equipment 400. interval. In the present embodiment, the first value is 1. When the networking information includes the connection time of the user equipment 400, the overwrite interval set by the setting module 121 is based on the networking time of the user equipment 400. When the networking information includes the network traffic of the user equipment 400, the overwrite interval set by the setting module 121 is based on the networked traffic of the user equipment 400.

The copy module 122 is configured to copy the bits representing the networking information in the flash memory 200 to the random access memory 300 when the network device 400 starts to connect to the network.

The recording module 123 is configured to find the first bit with the first value in the bit characterizing the network information in the random access memory 300 and record the index value in the variable n, where each time is set. When the overwrite interval arrives, the recording module 123 overwrites the bit corresponding to the variable n in the random access memory 300 to the second value, and increments the variable n by one. The bit that is written as the second value is used to represent the newly added networking information. In the present embodiment, the second value is zero.

The write module 124 is configured to determine whether the bit in the current random access memory 300 that represents the networked information exceeds the maximum network information that can be recorded by the flash memory 200, and is characterized in the current random access memory 300. When the bit of the networking information does not exceed the maximum networking information that can be recorded by the flash memory 200, the bit characterizing the newly added networking information in the random access memory 300 is written into the flash memory 200. In the present embodiment, the flash memory 200 divides a fixed size block from its storage space to store bits representing the networking information. The maximum networking information that can be recorded by the flash memory 200 is equal to the maximum value that can be recorded by the fixed size block.

The network monitoring module 130 is configured to set a network connection threshold of the user equipment 400, determine whether the network connection information in the current flash memory 200 reaches the network connection threshold of the user equipment 400, and connect in the current flash memory 200. The warning mechanism is activated when the network information reaches the network threshold of the user equipment 400. In this embodiment, when the networking information includes the networking time of the user equipment 400, the network connection threshold of the user equipment 400 includes the networking time threshold of the user equipment 400. For example, the network connection time of the user subscription is 12 hours, and the network connection time threshold of the user equipment 400 may be a preset value less than 12 hours, such as 11 hours, and the networking time in the current flash memory 200 reaches 11 When the hour is reached, the network monitoring module 130 starts the warning mechanism.

When the networking information includes the connected network traffic of the user equipment 400, the network connection threshold of the user equipment 400 includes the network traffic threshold value of the user equipment 400. For example, if the network traffic subscribed by the user is 120 MegaBytes, the threshold value of the network traffic of the user equipment 400 may be a preset value less than 120 MegaBytes, for example, 110 Megabytes, when the network traffic in the current flash memory 200 reaches 110 Megabytes. The network monitoring module 130 initiates an alert mechanism.

The warning mechanism in this embodiment may include a Light-Emitting Diode (LED).

In other embodiments, if the user is browsing a web page, the alert mechanism may also include dynamically replacing the existing web page and displaying a warning notification. The network monitoring module 130 can also directly interrupt the networking service when the networked information in the current flash memory 200 reaches the network connection threshold of the user equipment 400. For example, the network connection time of the user subscription is 12 hours, and the threshold time of the connection time of the user equipment 400 is also 12 hours. When the current connection time of the flash memory 200 reaches 12 hours, the network monitoring module is connected. 130 immediately interrupted the network service.

2 is a schematic diagram of an embodiment of the network device 100 of the present invention for recording networking information. In this embodiment, the network device 100 is configured to record the network connection time of the user equipment 400, and the network information of the user equipment 400 includes the network connection time of the user equipment 400. When the network device 100 starts to provide the network service for the user equipment 400, the setting module 121 can be used to initialize all the bits in the flash memory 200 that characterize the networking time to 1.

When the user equipment 400 is connected to the network for the first time, the copy module 122 copies the bits representing the networking time in the flash memory 200 to the random access memory 300, and the setting module 121 sets the user equipment 400 to overwrite the network during the network connection. The interval between the bits representing the networking information in the flash memory 200 is 1 minute, and the recording module 123 finds the first bit of 1 in the bit characterizing the networking time in the random access memory 300 and Its index value is recorded in the variable n. Since the user equipment 400 is connected for the first time, the initial values of the bits representing the networking time in the bits representing the networking time in the random access memory 300 are all 1, and the index of the first one is the index of the bit. That is 1, the variable n is equal to 1.

When the one-minute overwrite interval arrives (that is, after the user device 400 is connected for one minute), the recording module 123 overwrites the bit corresponding to the variable n in the random access memory 300 to 0, and The variable n is incremented by 1. In other words, the recording module 123 overwrites the first bit of the random access memory 300 with 1 as 0, and increments the variable n by 1. The bit that is overwritten with 0 is used to represent the new networking time.

At this time, the writing module 124 determines whether the bit characterizing the networking time in the current random access memory 300 exceeds the maximum networking time that the flash memory 200 can record. If the bit characterizing the networking time in the current random access memory 300 does not exceed the maximum networking time that the flash memory 200 can record, the write module 124 will only characterize the new random access memory 300. The bits of the extended network time are written to the flash memory 200. In other words, the write module 124 writes only the bits in the random access memory 300 that are written as 0 to the flash memory 200. As shown in FIG. 2, at this time, the first bit in the bit character representing the networking time in the flash memory 200 is 0, and the other bits are all 1.

When the 1 minute overwrite interval arrives again (ie, after the user device 400 is connected for 2 minutes), the recording module 123 overwrites the bit corresponding to the variable n of 2 in the random access memory 300 to 0, and This variable n is incremented by 1. In the present embodiment, the recording module 123 overwrites the second bit of the random access memory 300 with 1 as 0, and increments the variable n by 1. The bit that is written as 0 is also used to represent the new networking time.

At this time, the writing module 124 determines whether the bit characterizing the networking time in the current random access memory 300 exceeds the maximum networking time that the flash memory 200 can record. If the bit in the current random access memory 300 that represents the networking time does not exceed the maximum networking time that the flash memory 200 can record, the write module 124 only adds the representation in the random access memory 300. The bits of the networking time are written to the flash memory 200. In other words, the write module 124 writes only the bits in the random access memory 300 that are overwritten to zero into the flash memory. As shown in FIG. 2, at this time, the first and second bits in the bits representing the networking time in the flash memory 200 are 0, and all other bits are 1.

By analogy, when the user equipment 400 is connected for n minutes, the first to nth bits in the bits representing the networking time in the flash memory 200 are 0, and all other bits are 1.

Therefore, the bits characterization of the networking time in the flash memory 200 reliably record the networking time of the user equipment 400 in order to manage the network connection status of the user equipment 400.

FIG. 3 is a schematic diagram of another embodiment of the network device 100 of the present invention for recording network information. In this embodiment, the network device 100 is configured to record the connected network traffic of the user equipment 400, and the network connection information of the user equipment 400 includes the networked traffic of the user equipment 400. When the network device 100 starts to provide the network service for the user equipment 400, the setting module 121 can be used to initialize all the bits in the flash memory 200 that represent the networked traffic to 1.

When the user equipment 400 is connected to the network for the first time, the copy module 122 copies the bits representing the networked traffic in the flash memory 200 to the random access memory 300, and the setting module 121 sets the user equipment 400 to overwrite during the network connection. The interval in the flash memory 200 for characterizing the networking information is 1 KiloByte (KB) of network traffic, and the recording module 123 finds the first one in the random access memory 300 that characterizes the network traffic. A bit of 1 and its index value is recorded in the variable n. Since the user equipment 400 is connected for the first time, the initial values of the bits representing the network traffic in the bits representing the network traffic in the random access memory 300 are all 1, and the index of the first one is the index of the bit. That is 1, the variable n is equal to 1.

When the 1 KB overwrite interval arrives (ie, after the user device 400 uploads 1 KB of network traffic), the recording module 123 overwrites the bit corresponding to the variable n in the random access memory 300 to 0, and the The variable n is incremented by 1. In other words, the recording module 123 overwrites the first bit of the random access memory 300 with 1 as 0, and increments the variable n by 1. The bit that is overwritten with 0 is used to characterize the new network traffic.

At this time, the write module 124 determines whether the bit in the current random access memory 300 that represents the networked traffic exceeds the maximum network traffic that the flash memory 200 can record. If the bit characterizing the network traffic in the current random access memory 300 does not exceed the maximum network traffic that can be recorded by the flash memory 200, the write module 124 only adds the representation in the random access memory 300. The bits of the networked traffic are written to the flash memory 200. In other words, the write module 124 writes only the bits in the random access memory 300 that are written as 0 to the flash memory 200. As shown in FIG. 3, at this time, the first bit in the bit character representing the network traffic in the flash memory 200 is 0, and the other bits are all 1.

When the 1 KB overwrite interval arrives again (ie, after the user device 400 uploads 2 KB of network traffic), the recording module 123 overwrites the bit corresponding to the variable n of 2 in the random access memory 300 to 0, and This variable n is incremented by 1. In the present embodiment, the recording module 123 overwrites the second bit of the random access memory 300 with 1 as 0, and increments the variable n by 1. The bit that is written as 0 is also used to characterize the new network traffic.

At this time, the write module 124 determines whether the bit in the current random access memory 300 that represents the networked traffic exceeds the maximum network traffic that the flash memory 200 can record. If the bit characterizing the network traffic in the current random access memory 300 does not exceed the maximum network traffic that can be recorded by the flash memory 200, the write module 124 only adds the representation in the random access memory 300. The bits of the networked traffic are written to the flash memory 200. In other words, the write module 124 writes only the bits in the random access memory 300 that are overwritten to zero into the flash memory. As shown in FIG. 3, at this time, the first and second bits in the bits representing the network traffic in the flash memory 200 are 0, and all the other bits are 1.

By analogy, after the user device 400 uploads the nKB network traffic, the first to nth bits in the bits representing the network traffic in the flash memory 200 are 0, and all other bits are 1.

Therefore, the bits in the flash memory 200 that characterize the networked traffic reliably record the networked traffic of the user equipment 400 in order to manage the networked condition of the user equipment 400.

FIG. 4 is a flow chart of an embodiment of networking information of the network device 100 for controlling the user equipment 400 of the present invention.

In step S400, the network monitoring module 130 sets the network connection threshold of the user equipment 400. In this embodiment, when the networking information of the user equipment 400 includes the network connection time of the user equipment 400, the network connection threshold of the user equipment 400 includes the networking time threshold of the user equipment 400. When the networking information of the user equipment 400 includes the networked traffic of the user equipment 400, the network connection threshold of the user equipment 400 includes the network traffic threshold value of the user equipment 400.

In step S402, the networked service module 110 provides a network service for the user equipment 400.

In step S404, the networked information recording module 120 records the network information of the user equipment 400. This step will be explained in detail in FIG.

In step S406, the network monitoring module 130 determines whether the network information of the user equipment 400 reaches its networking threshold.

If the network information of the user equipment 400 does not reach the network threshold, the process returns to step S402, and the network service module 110 continues to provide the network service for the user equipment 400.

If the networking information of the user equipment 400 reaches its networking threshold, the network monitoring module 130 starts the warning mechanism in step S408. In this embodiment, the network connection threshold of the user equipment 400 is smaller than the networking information subscribed by the user. For example, the network connection time of the user subscription is 12 hours, and the network equipment time threshold of the user equipment 400 may be a preset value less than 12 hours, such as 11 hours, when the connection time of the user equipment 400 reaches 11 At the hour, the network monitoring module 130 immediately starts the warning mechanism.

In other embodiments, the network connection threshold of the user equipment 400 may also be equal to the network information subscribed by the user. Correspondingly, in step S408, the network monitoring module 130 interrupts the networking service. For example, the network connection time of the user subscription is 12 hours, and the network connection time threshold of the user equipment 400 is 12 hours. When the connection time of the user equipment 400 reaches 12 hours, the network monitoring module 130 immediately interrupts the connection. Web service.

FIG. 5 is a flow chart of an embodiment of a method for recording network information by the network device 100 of the present invention. In this embodiment, the method for the network device 100 to record the networking information is implemented by the function module in FIG. 1.

In step S500, the setting module 121 initializes the bit characterizing the networking information in the flash memory 200 to the first value. In the present embodiment, the first value is 1.

In step S502, the copy module 122 copies the bits representing the networking information in the flash memory 200 to the random access memory 300 when the user equipment 400 starts networking.

In step S504, the recording module 123 finds the first bit with the first value in the bit characterizing the networking information in the random access memory 300 and records its index value in the variable n.

In step S506, the setting module 121 sets an interval for overwriting the bits of the flash memory 200 that represent the networking information during the networking of the user equipment 400. In this embodiment, when the networking information of the user equipment 400 includes the networking time of the user equipment 400, the set overwrite interval is based on the networking time of the user equipment 400. When the networking information of the user equipment 400 includes the networked traffic of the user equipment 400, the set overwrite interval is based on the networked traffic of the user equipment 400.

In step S508, the recording module 123 overwrites the bit corresponding to the variable n in the random access memory 300 to the second value each time the set overwrite interval arrives, and increments the variable n by one. The bit that is written as the second value is used to represent the newly added networking information. In the present embodiment, the second value is zero.

In step S510, the writing module 124 determines whether the bit characterizing the networking information in the current random access memory 300 exceeds the maximum networking information that the flash memory 200 can record. In this embodiment, the flash memory 200 divides a fixed-size block from its storage space to store a bit characterizing the networking information, and the maximum network information that the flash memory 200 can record is equal to the fixed. The maximum value that can be recorded by a block of size.

If the bit characterizing the networking information in the current random access memory 300 does not exceed the maximum networking information that can be recorded by the flash memory 200, the writing module 124 will randomly access the memory 300 in step S512. The bits characterizing the newly added networking information are written to the flash memory 200.

The above steps S508-S512 are cyclically executed during the networking of the user equipment 400 until the user equipment 400 stops networking or the bits representing the networking information in the current random access memory 300 exceed the maximum number of records that can be recorded by the flash memory 200. Network information so far.

In the embodiment of the present invention, since the write module 124 only writes the bit in the random access memory 300 that represents the newly added networking information into the flash memory 200, that is, only the flash memory 200 is made. The write action is not erased, so that the network device 400 can be prevented from being powered off due to data loss during erasing. In addition, the copy module 122 and the write module 124 both copy and write the flash memory 200 in units of bits, thereby saving the use space of the flash memory 200.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
