Hereinafter, each step of the data service communication method in the exemplary embodiment of the present disclosure will be described in more detail with reference to the accompanying drawings and embodiments.

Fig. 2 shows a flow chart of a data service communication method in an embodiment of the present disclosure. For example, the method provided by the embodiment of the present disclosure may be executed by the terminal device 700 shown in FIG. 1.

Referring to FIG. 2, the data service communication method 10 includes:

In step S102, when the first SIM card and the second SIM card meet the preset conditions, periodically detect the received data volume and the sent data volume of the first SIM card currently in data service communication within each period.

When the terminal device 700 performs data services through the first SIM card, the signal condition of the first SIM card and the signal condition of the second SIM card can be monitored in real time.

In some embodiments, for example, the signal strength of the first SIM card and the second SIM card may be monitored separately. For example, the signal strength may be RSRP (Reference Signal Receiving Power) of the signals of the first SIM card and the second SIM card. RSRP refers to the measured received power on the reference signal. Taking the 4G mobile communication system LTE (Long Term Evolution) as an example, RSRP refers to all REs (Resource Elements) of the cell-specific reference signal (Reference Signal). ) Is the average value of the received signal power.

Alternatively, the signal strength may also be RSSI (Received Signal Strength Indicator) of the signals of the first SIM card and the second SIM card. RSSI refers to the received signal strength indicator, which includes reference signals, data signals, interference signals, and noise signals. Still taking the LTE system as an example, the RSSI usually refers to the average value of the total power on the OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) symbol containing the reference signal of the antenna port 0.

The foregoing preset condition may include, for example, that the absolute value of the difference between the signal strength of the first SIM card and the signal strength of the second SIM card is less than or equal to the preset signal strength threshold THs. Taking the signal strength as the RSSP as an example, the signal strength threshold THs may be set to 10 dB, for example.

In some embodiments, the signal quality of the signal of the first SIM card and the signal of the second SIM card can also be detected separately. The signal quality may be, for example, SINR (Signal to Interference plus Noise Ratio, signal to interference and noise ratio). SINR refers to the ratio of the received useful signal power to the received interference signal and noise power, which is used to measure the quality of the signal.

Alternatively, the signal quality can also be SNR (Signal Noise Ratio, SNR). SNR refers to the ratio of useful signal power to the sum of interference and noise power, which can directly reflect the quality of the received signal.

Alternatively, the signal quality may also be RSRQ (Reference Signal Received Quality, reference signal received quality), which can usually be calculated by RSRP and RSSI.

The foregoing preset condition may include, for example, that the absolute value of the difference between the signal quality of the first SIM card and the signal quality of the second SIM card is less than or equal to the preset signal quality threshold THq.

In some embodiments, for example, the signal strength and signal quality of the first SIM card and the second SIM card can also be monitored at the same time. The aforementioned preset conditions can include, for example: the signal strength of the first SIM card and the signal of the second SIM card. The absolute value of the difference between the intensities is less than or equal to the preset signal strength threshold THs, and the absolute value of the difference between the signal quality of the first SIM card and the signal quality of the second SIM card is less than or equal to the preset signal quality Threshold THq.

When the above-mentioned preset condition is satisfied between the signal of the first SIM card and the signal of the second SIM card, the received data amount Rx ^{Δ of the first SIM card currently undergoing data service communication in each period can be periodically determined.} And the amount of sent data Tx ^Δ for detection.

In some embodiments, the first SIM card may be, for example, a SIM card configured as a primary card, and the second SIM card may be, for example, a SIM card configured as a secondary card. Or, when the data service is switched to the secondary card for communication, the first SIM card may also be the secondary card, and the second SIM card may be the primary card.

The period may be configured as 5 seconds, for example, but the present disclosure is not limited to this, and in actual applications, the period may be set according to actual conditions. Or, in some embodiments, the period may also be set by the user through a user interface, for example. For example, several cycle time options can be provided to the user, which can be selected by the user in the interface.

In the nth cycle, the received data amount Rx ^{Δn of the} first SIM card in the cycle time can be calculated by the following formula (1), and the sent data amount Tx ^Δn can be calculated by the following formula (2).

Rx ^Δn ＝Rx _n -Rx _n-1 ……(1)

Tx ^Δn = Tx _n -Tx _n-1 ……(2)

Among them, Rx _n is the received data amount accumulated by the first SIM card in the first n cycles, and Rx _n-1 is the received data amount accumulated by the first SIM card in the first n-1 cycles. Tx _n is the amount of transmitted data accumulated by the first SIM card in the previous n cycles, and Tx _n-1 is the amount of transmitted data accumulated by the first SIM card in the previous n-1 cycles.

It should be noted that the amount of data sent and received in each cycle time of statistics can be the amount of data in the application layer, for example, the amount of data in the sending and receiving buffers in the application layer client software participating in data service communication. . Alternatively, the amount of sent data and the amount of received data may also be the amount of data in the receiving and sending data buffer in the mobile communication protocol adopted by the first SIM card, such as the buffer in the MAC (Medium Access Control) layer.

In step S104, a switching strategy between the first SIM card and the second SIM card is determined according to the amount of received data and the amount of sent data within the current cycle time.

After obtaining the received data volume and the sent data volume in each cycle time in turn, you can determine whether to switch the currently communicating data service ^{according to the Rx Δ} and the sent data volume Tx ^{Δ in the current cycle time in turn during each cycle.} Go to the second SIM card.

In some embodiments, when it is determined to switch the data service currently in communication to the second SIM card, the terminal device 700 also needs to send a data switch related message to the network device registered with it through the first SIM card to notify the network The device switches the transmission path of the current data service in the core network. For example, the network device connected to the second SIM card is notified through the network device connected to the first SIM card to establish a new data transmission path for it, and the routing device is notified to route the subsequent data of the data service to be associated with the second SIM card On the new data transmission path.

According to the data service communication method provided by the embodiment of the present disclosure, when it is ensured that the signal of the first SIM card that is currently in data service communication and the signal of the second SIM card that is not in data service communication meet a preset condition, Through real-time monitoring of the received data volume and the sent data volume of the first SIM card currently in data service communication, it is judged whether it is necessary to perform data service switching, and the SIM card can be processed in time before the data service is stuck. Switch to ensure smooth data service communication and improve user experience.

Fig. 3 shows a flowchart of another data service communication method in an embodiment of the present disclosure. Different from the data service communication method 10 shown in FIG. 2, the data service communication method shown in FIG. 3 further shows an exemplary implementation of the foregoing step S104.

As shown in FIG. 3, step S104 may include:

In step S1042A, when the amount of received data within the current cycle time is 0, it is determined whether the amount of transmitted data within the current cycle time is greater than the first threshold TH1.

If the amount of sent data in the current cycle time is greater than the first threshold TH1, then go to step S1044A; if the amount of sent data in the current cycle time is less than the first threshold TH1, go to step S1046A.

Assuming that the current period is n, if the amount of received data Rx ^Δn is 0, it is determined whether the amount of transmitted data Tx ^Δn within the current period is greater than the first threshold TH1.

If it is detected that the amount of received data in the current cycle is 0, it may cause the downlink data to be stuck, and it is necessary to determine whether to switch the data service to the second SIM card according to the amount of transmitted data in a timely manner.

In step S1044A, it is determined to switch the data service to the second SIM card.

When the amount of sent data Tx ^{Δn in the} current cycle time is greater than the first threshold TH1, it is determined to switch the data service to the second SIM card.

In step S1046A, continue to detect the received data volume and the sent data volume of the first SIM card in each cycle time in the subsequent cycle.

Still taking the current cycle as cycle n as an example, when the transmitted data amount Tx ^{Δn in the} current cycle time is less than the first threshold TH1, continue to detect the received data amount and the transmitted data amount of the first SIM card in each cycle time in the subsequent cycle. Such as detecting the amount of received data and the amount of sent data in the subsequent period n+1, period n+2, etc.

In step S1048A, it is determined whether the cumulative value of the amount of data sent by the first SIM card in the subsequent cycles is greater than the first threshold TH1, and whether the amount of data received by the first SIM card in each of the cycles is equal to 0.

That is, it is determined whether the received data amount of the first SIM card in the following several cycles are all 0, and whether the accumulated transmitted data amount of these several cycles is greater than the first TH1.

If the cumulative value of the amount of data sent by the first SIM card in the subsequent cycles is greater than the first threshold TH1, and the amount of data received by the first SIM card in each of the cycles is 0, then step S1044A is entered, Determine to switch the data service to the second SIM card.

Otherwise, if the amount of received data within a certain period of time in the subsequent period is not 0 before the accumulated value is not greater than the first threshold TH1, the card switching for the data service is not performed.

Fig. 4 shows a flowchart of yet another data service communication method in an embodiment of the present disclosure. Different from the data service communication method 10 shown in FIG. 2, the data service communication method shown in FIG. 4 further shows another exemplary implementation of the above step S104.

As shown in Fig. 4, step S104 may include:

In step S1042B, when the amount of received data within the current cycle time is not 0, it is determined whether the amount of received data within the current cycle time is greater than the amount of sent data.

If the amount of received data in the current cycle time is greater than the amount of sent data, the switching of the card used for the data service is not performed.

Otherwise, if the amount of received data in the current cycle time is less than the amount of sent data, step S1044B is entered.

Assuming that the current cycle is n, if the amount of received data Rx ^{Δn is} not 0, it is determined whether the amount of received data Rx ^Δn within the current cycle time is greater than the amount of transmitted data Tx ^Δn .

If the amount of received data Rx ^{Δn in the} current cycle time is greater than the amount of transmitted data Tx ^Δn , it indicates that the current downlink data can be received normally, and there is no need to switch the data service to the second SIM card. Since the amount of data on the downlink is usually greater than the amount of uplink data (except for services such as file uploads by users), if the amount of received data Rx ^{Δn in the} current cycle time is less than the amount of transmitted data Tx ^Δn , it is necessary to further determine whether The data service needs to be switched to the second SIM card.

In step S1044B, it is determined whether the ratio between the amount of received data and the amount of transmitted data in the current cycle time is less than the second threshold TH2.

If the ratio between the amount of received data and the amount of sent data in the current cycle time is less than the second threshold TH2, go to step S1046B; otherwise, if the ratio between the amount of received data and the amount of sent data in the current cycle time is greater than the second threshold TH2, go to step S1052B.

Still taking the current period as period n as an example, it is judged whether the ratio Rx ^Δn /Tx ^{Δn between the amount of received data Rx Δn} and the amount of transmitted data Tx ^Δn within the period of period n is smaller than the second threshold TH2.

In step S1046B, continue to detect the received data volume and the sent data volume of the first SIM card in the next cycle time.

When TH2 ratio ^Rx Δn between the amount of data received in the current time period and the amount of transmission data ^Rx Δn Tx ^Δn / Tx ^Δn less than the second threshold value, continues to be detected during the next cycle, cycle time period n + 1 the first SIM card The amount of received data Rx ^Δn+1 and the amount of transmitted data Tx ^Δn+1 .

In step S1048B, it is determined whether the ratio between the amount of received data and the amount of transmitted data of the first SIM card in the next cycle time is still less than the second threshold TH2.

If the ratio between the received data volume and the sent data volume of the first SIM card in the next cycle is still less than the second threshold TH2, go to step S1050B; otherwise, if the received data volume of the first SIM card in the next cycle If the ratio to the amount of sent data is greater than the second threshold TH2, the switching of the card used for the data service is not performed.

It is judged whether the ratio Rx ^Δn+1 /Tx ^Δn+1 between the received data amount Rx ^Δn+1 and the transmitted data amount Tx ^Δn+1 within the period of period n+1 is still smaller than the second threshold TH2.

In step S1050B, it is determined to switch the data service to the second SIM card.

When the ratio Rx ^Δn+1 /Tx ^Δn+1 between the received data amount Rx ^Δn+1 and the transmitted data amount Tx ^Δn+1 in the period n+1 period is still less than the second threshold TH2, it is determined to switch the data service To the second SIM card.

In step S1052B, continue to detect the amount of received data and the amount of sent data of the first SIM card in each cycle within a predetermined number of subsequent cycles.

When the ratio Rx ^Δn /Tx ^{Δn between the amount of received data Rx Δn} and the amount of transmitted data Tx ^Δn within the period of period n is greater than the second threshold TH2, continue to detect the subsequent preset number of cycles of the first SIM card in each cycle time The amount of received data and the amount of sent data within.

Taking the preset number of 2 as an example, continue to detect the amount of received data and the amount of transmitted data within the respective period of period n+1 and period n+2.

In step S1054B, it is determined whether the ratio between the amount of received data and the amount of transmitted data of the first SIM card in the preset number of subsequent cycles is less than the second threshold TH2.

If the ratio between the amount of received data and the amount of transmitted data of the first SIM card in the preset number of subsequent cycles is less than the second threshold TH2, go to step S1050B; otherwise, if the first SIM card The ratio between the amount of received data and the amount of transmitted data within the preset number of subsequent cycles is not all less than the second threshold TH2, and the switching of the card used for the data service is not performed.

Still taking the preset number of 2 as an example, when the ratio Rx ^Δn+1 /Tx ^{Δn+1 between the amount of received data Rx Δn+1} and the amount of transmitted data Tx ^{Δn +1 in the period of period n+1 is} less than the first When the second threshold TH2, and the ratio Rx ^Δn+2 /Tx ^{Δn+2 between the received data amount Rx Δn+2} and the transmitted data amount Tx ^Δn +2 in the period of period n+2 is also less than the second threshold TH2, Go to step S1050B to determine to switch the data service to the second SIM card.

If the ratio Rx ^Δn+1 /Tx ^Δn+1 and/or the ratio Rx ^Δn+2 /Tx ^{Δn+2 is} greater than the second threshold TH2, the switching of the card for the data service is not performed.

Usually the amount of data sent is 0, which may be caused by poor uplink quality, but it may also be because there is no uplink data to be sent currently. If there is downlink data transmission, the uplink usually needs to send a corresponding feedback signal, so that the amount of transmitted data cannot be zero. Therefore, when there is no uplink data to be sent, it may also be because there is no downlink data to be sent. In this case, you can also determine whether it needs to be sent by first judging whether the amount of sent data in each cycle time is 0. The data service is switched to the second SIM card, thereby providing a simpler and more efficient decision-making method.

In step S1046C, it is determined to switch the data service to the second SIM card.

When the amount of sent data Tx ^{Δn in the} current cycle time is greater than the first threshold TH1, it is determined to switch the data service to the second SIM card.

In step S1048C, continue to detect the received data volume and the sent data volume of the first SIM card in each cycle time in the subsequent cycle.

That is, it is determined whether the received data amount of the first SIM card in the following several cycles are all 0, and whether the accumulated transmitted data amount of these several cycles is greater than the first TH1.

If the cumulative value of the amount of data sent by the first SIM card in the subsequent cycles is greater than the first threshold TH1, and the amount of data received by the first SIM card in each of the cycles is 0, then step S1046C is entered, Determine to switch the data service to the second SIM card.

Otherwise, if the amount of received data within a certain period of time in the subsequent period is not 0 before the accumulated value is not greater than the first threshold TH1, the card switching for the data service is not performed.
