It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a schematic flowchart of a method for allocating a connection path according to an embodiment of the present invention. In the embodiment of the present invention, the method includes:

S101. Obtain data transmission/reception time information and busy/idle time information in a currently used connection path.

Specifically, the connection path allocation method is configured to allocate a communication channel of the wireless router to the mobile terminal, where the mobile terminal may be, but not limited to, a smart phone, a tablet computer, or a smart wearable electronic device, etc., the wireless router It is preferably a different type of wireless router such as a wifi wireless router. After starting, the wireless router forms a plurality of communication channels for different mobile terminals to connect. In fact, the communication channel acts as a connection path between the mobile terminal and the wireless router to implement data transmission. Each communication channel is provided with an authentication procedure such as password authentication or token identification, thereby ensuring the security of data transmission in each communication channel; and each communication channel is independent of data transmission between each other, thereby preventing different communication Crosstalk occurs in data transmission between channels.

After the mobile terminal and the wireless router are connected through the communication channel, corresponding uplink data and downlink data are formed in the communication channel, and the uplink data and the downlink data substantially respectively include the wireless router transmitting to the mobile terminal. Data information and data information transmitted by the mobile terminal to the wireless router. During the working process, the wireless router performs uplink data and downlink data interaction with the mobile terminal; during the interaction, the data transmission clock unit acquires data transmission time information and data reception time information, wherein the data transmission time information Refers to the time TS consumed by the mobile terminal to transmit a data code to the wireless router through the communication channel, and the data receiving time information The time TR consumed by the wireless router to transmit the data code to the mobile terminal over the communication channel is implemented. After the mobile terminal establishes a corresponding communication channel with the wireless router, the control unit sends a trigger instruction to the data transmission clock unit, where the trigger instruction is used to indicate to the data transmission clock unit that timing detection of data transmission/reception time information is performed. . The data transmission clock unit can separately detect uplink data and downlink data in the communication channel during the timing detection process. In fact, the communication channel is further divided into an uplink data subchannel and a downlink data subchannel, and the uplink data is used. The subchannel and the downlink data subchannel can only transmit the uplink data and the downlink data respectively. Accordingly, the data transmission clock unit can include a transmit data timing subunit and a receive data timing subunit, the transmit data timing subunit and the receive data. The timing subunit is capable of acquiring corresponding data transmission time information and data reception time information in the uplink data subchannel and the downlink data subchannel, respectively. The data transmission clock sub-unit may store the acquired data transmission time information and data reception time information in a storage unit in the form of a statistical list.

After the wireless router is turned on, the channel state identifying unit determines whether the communication channel is in a busy state or an idle state by identifying wireless signal energy in the communication channel. Since when a certain communication channel is occupied, the mobile terminal and the wireless router transmit data in the form of a wireless signal in the communication channel; based on the data transmission process, the channel state identification unit detects and detects a certain communication channel. The wireless signal energy, that is, the electromagnetic wave corresponding to the spectrum segment, can determine whether the communication channel is in a busy state or an idle state. The specific working process of the channel energy identification unit is: first, the channel state identification unit acquires the current wireless signal energy value E within a certain communication channel, and the wireless signal energy value E and the energy threshold stored in the storage unit The ET compares, if the wireless signal energy value E is less than the energy threshold ET, the channel state identifying unit feeds back to the control unit the signal that the communication channel is idle, and detects the duration of the communication channel in the idle state; The wireless signal energy value E is greater than or equal to the energy threshold ET, and the channel state identifying unit feeds back to the control unit the signal that the communication channel is busy, and will detect the duration of the communication channel in the busy state. Subsequently, the channel state identifying unit transmits the idle state duration and the busy state duration to the storage unit for saving.

Then, the control unit acquires four time information of the data transmission time, the data reception time, the idle state duration, and the busy state duration from the storage unit, and respectively the four time information and the communication channel The duration can be used to calculate the four time information and the The ratio of the four times corresponding to the duration is used.

S102. Acquire, according to the data sending/receiving time information and the busy/idle time information, a data transmission quality parameter of the currently used connection path.

Specifically, the control unit calculates the four time ratio values obtained in the previous step and the error rate of data transmission between the mobile terminal and the wireless router to obtain data transmission for the current communication channel. A quality parameter, the data transmission quality parameter is used to evaluate the data transmission quality of the current communication channel. The error rate RATE of the data transmission between the mobile terminal and the wireless router is obtained by the data packet detecting unit; the data error obtaining unit acquires the data packet sent between the mobile terminal and the wireless router. The total number of times N and the number of erroneous data message transmissions M, and the error data transmission number M is divided by the total number of times the data message is sent to calculate the error of data transmission between the mobile terminal and the wireless router. Rate RATE, ie RATE=M/N. In essence, the data packet detecting unit obtains the total number of times of the data packet N and the number of times the erroneous data packet is sent by counting. The data packet detecting unit includes a data packet counting subunit for detecting the total number N of the data packets, and an erroneous data packet counting subunit for detecting the erroneous data packet number M; When the data packet is transmitted between the mobile terminal and the wireless router, the data packet counting sub-unit realizes counting the data packet by counting the pulse signal; meanwhile, the error data packet counting sub-unit is only in the When the mobile terminal or the wireless router feeds back a data message error, the counting operation of the pulse signal is performed.

The data message detecting unit saves the error rate RATE to the storage unit and transmits it to the control unit. The control unit calculates the data transmission quality parameter based on the four time ratio values and the error rate RATE. The data transmission quality parameter is used to measure the usage efficiency of the communication channel and the data transmission accuracy rate. The larger the data transmission quality parameter, the better the data transmission quality of the communication channel.

S103. Determine, according to the data transmission quality parameter, whether to perform reallocation of the connection path to the mobile terminal.

Specifically, after the control unit calculates the data transmission quality parameter, the data transmission quality parameter is compared with a communication channel quality threshold. When the data transmission quality parameter is less than the communication channel quality threshold, the control unit suspends a communication channel between the current mobile terminal and the wireless router, and connects the mobile terminal to the wireless router through another communication channel; The When the data transmission quality parameter is greater than or equal to the communication channel quality threshold, the control unit maintains the current communication channel working state between the mobile terminal and the wireless router. Wherein the selection of the other communication channel is performed based on data transmission quality parameters of all communication channels in the wireless router. Generally, the control unit uses the communication channel having the highest data transmission quality parameter as the new communication channel. The first choice object.

As can be seen from the foregoing embodiment, the connection path allocation method calculates data transmission quality parameters of the currently used connection path by acquiring data transmission/reception time information and busy/idle time information in the currently used connection path, and the data transmission quality is The parameter is used to measure the connection path, that is, the use efficiency of the communication channel and the data transmission correct rate; in addition, the method further determines whether to perform reallocation of the connection path to the mobile terminal based on the data transmission quality parameter, the method The method can perform communication channel allocation for data transmission characteristics of different mobile terminals, thereby improving the use efficiency of the connection path such as the communication channel and the data transmission correct rate.
