This embodiment uses the dual USIM cards in the terminal device and the different network frequency bands corresponding to each USIM card to achieve the terminal device's ability to intelligently switch networks in multiple scenarios.

[0061] In one embodiment of the present invention, the method for performing network switching by a terminal device based on a network switching system includes:

[0063] Step 2: The big data platform determines whether the services and network residences performed within the coverage area of ​​the current positioning position meet the historical service types and traffic according to the service data information of the terminal device, and determines the target residence frequency according to the judgment result.

[0064] Specifically, the terminal device determines the target USIM card according to the data service request and the network status of each of the two USIM cards, including:

[0065] Step 101: When the terminal device makes a data service request, the second USIM card of the two USIM cards periodically sends a heartbeat packet to the first USIM card to confirm the network status of the first USIM card; wherein the terminal communication unit is provided with a data service by the first USIM card of the two USIM cards;

[0066] Step 102: If the second USIM card receives a heartbeat reply from the first USIM card within a preset time period, the collaborative processing unit collects reference signal received power RSRP values ​​of the first USIM card and the second USIM card respectively;

[0068] Step 104: compare the reference signal received power RSRP values ​​of the first USIM card and the second USIM card, and select the USIM card with a better current network status as the target USIM card according to the comparison result.

[0069] Specifically, if the second USIM card does not receive a heartbeat reply from the first USIM card within a preset time period, performing a USIM card switch includes:

[0070] Step 1031: If the second USIM card does not receive a heartbeat reply from the first USIM card within the preset time period, the collaborative processing unit sends a message carrying an instruction to switch USIM cards to the terminal communication unit;

[0071] Step 1032: In response to the message carrying the instruction to switch the USIM card, the terminal communication unit switches to providing data services for the second USIM card of the two USIM cards and enters a preparation phase for initiating the data service.

[0072] Specifically, the big data platform determines whether the services and network residences performed in the coverage area of ​​the current positioning position meet the historical service types and traffic according to the service data information of the terminal device, and determines the target residence frequency according to the judgment result, including:

[0073] Step 201: When the target USIM card enters the preparation stage for initiating a data service, the positioning function unit reports the current location of the located terminal device to the big data platform in real time;

[0074] Step 202: The big data platform determines whether the services and network residency performed in the coverage area of ​​the current positioning position meet the historical service type and traffic according to the service data information of the terminal device.

[0075] Step 203: If the services and network residences performed in the coverage area of ​​the current positioning location meet the historical service types and traffic, the big data platform determines the current residence frequency band of the target USIM card as the target residence frequency band of the target USIM card;

[0076] Step 204: If the services and network residency performed in the coverage area of ​​the current positioning position do not meet the historical service types and traffic, the big data platform initiates a change to the current residency frequency band of the target USIM card.

[0077] Specifically, if the services and network residency performed in the coverage area of ​​the current positioning position do not meet the historical service types and traffic, the big data platform initiates a change to the current residency frequency band of the target USIM card, including:

[0078] Step 2041: The big data platform sends a message carrying a change frequency indication to the collaborative processing unit;

[0079] Step 2042: The collaborative processing unit forwards the message carrying the frequency change indication to the terminal communication unit;

[0080] Step 2043: The terminal communication unit changes the current resident frequency band of the target USIM card in response to the message carrying the frequency change indication.

[0081] The working principle of the above technical solution is as follows: first, the terminal device (such as user equipment User Equipment) UE makes a data service request; the terminal communication module is written with a code by default that USIM card 1 provides data services first; USIM card 2 sends a heartbeat packet to USIM card 1 at regular intervals to confirm the current network status of USIM card 1; when USIM card 2 receives the heartbeat reply of USIM card 1 within a preset time period, the collaborative processing unit collects the RSRP values ​​of the dual USIM cards and compares them; after the collaborative processing unit compares, if USIM card 1 is superior to USIM card 2, USIM card 1 performs the preparation stage for initiating data services;

[0082] Then, when USIM card 1 enters the preparation stage, the positioning function unit reports the current positioning position of the terminal device to the big data platform in real time. The big data platform uses the big data model to judge the historical service type and traffic of the current positioning position A of the terminal device. If the historical service type and traffic of the current positioning position A are met, the data service is carried out by the current resident frequency band of USIM card 1.

[0083] If the big data platform determines that the services and network residence performed within the coverage area of ​​the terminal device's current location do not meet the historical service types and traffic, the big data platform will send a message carrying a frequency change indication to the collaborative processing unit, and the collaborative processing unit will send the message carrying the frequency change indication to the terminal communication module, and the terminal communication module will change the current resident frequency band of the target USIM card, and perform data services at the changed resident frequency band.

[0084] When USIM card 1 does not receive a heartbeat reply within a preset time period, the collaborative processing unit sends a message carrying an instruction to switch USIM card to the terminal communication module, so that the terminal communication module switches USIM card 2 to perform a data service preparation phase; and uses USIM card 2 to enter the preparation phase, and performs data services for all execution steps of the positioning function unit until the changed resident frequency band;

[0085] On the other hand, when the collaborative processing unit compares the RSRP of the dual USIM cards, if USIM card 2 is better than USIM card 1, it switches to using USIM card 2 to enter the preparation phase, and performs data services for all execution steps of the positioning function unit until the changed resident frequency band;

[0086] Finally, the data service ends and the above steps are performed according to the phenomenon before each data service starts.

[0087] The effect of the above technical solution is as follows: the above technical solution of this embodiment includes a terminal device and a big data platform, wherein the terminal device includes a collaborative processing unit, a positioning function unit and a terminal communication module; two USIM card slots are arranged in the terminal communication module, each of which holds a USIM card; the collaborative processing unit is used to obtain the current network status and service data information of the terminal device from the terminal communication module, and process the switching between the dual USIM card networks and the switching of the frequency band corresponding to the target USIM card after the switching; the terminal communication module has radio frequency and baseband functions for processing signal modulation, demodulation, encoding and decoding and power amplification, as well as routing forwarding and data service processing; the positioning function unit The element is used to perform real-time positioning of the terminal device to obtain the current positioning position of the terminal device; the big data platform is used to perform service and network residence analysis on the terminal device in the coverage area of ​​the current positioning position according to the current network status, service data information and current positioning position of the terminal device, and obtain the target USIM card and its target residence frequency band corresponding to the terminal device when the terminal device is in the optimal working mode; the collaborative processing unit is used to perform the data service requested by the terminal device through the target residence frequency band of the target USIM card. The present application realizes that the terminal device can intelligently switch networks in multiple scenarios through dual USIM cards in the terminal device and different network frequency bands corresponding to each USIM card.

[0088] In one embodiment of the present invention, the method for obtaining the preset time period is as follows:

[0089] The first step is to extract the first influencing parameter and the second influencing parameter of the preset time period, wherein the first influencing parameter includes the heartbeat packet sending frequency, the network delay duration and the network fluctuation tolerance duration; the second influencing parameter includes the network packet loss rate and the signal strength;

[0090] Step 2: Use the first influencing parameter to obtain a first time period parameter; wherein the first time period parameter is obtained by the following working hours:

[0091]

[0092] Among them, T 01 represents the first time period parameter; f represents the heartbeat packet sending frequency; Δf represents the change amplitude corresponding to the heartbeat packet sending frequency; n represents the total number of heartbeat packets sent by the two USIM cards included in the terminal device; T yi represents the network delay duration corresponding to the i-th data transmission; T max' represents the network fluctuation tolerance time; t represents the compensation coefficient, and the compensation coefficient is obtained by the following formula:

[0093]

[0094] Where, t represents the compensation coefficient; T yp represents the average network delay time corresponding to n heartbeat packets sent; T yz Indicates the median network delay corresponding to n heartbeat packets sent; T ymax Indicates the maximum value of the network delay corresponding to n heartbeat packets sent; T max' Indicates the tolerance time for network fluctuations;

[0095] Step 3: Use the second influencing parameter to obtain a second time period parameter; wherein the second time period parameter is obtained by the following working hours:

[0096]

[0097] Among them, T 02 represents the second time period parameter; f represents the heartbeat packet sending frequency; k represents the preset packet loss rate weight value; P represents the packet loss rate corresponding to the current terminal device; B d Indicates the signal strength of the current terminal device; B y Indicates the preset signal strength threshold; T max' Indicates the network fluctuation tolerance time; T yp Indicates the average network delay time corresponding to n heartbeat packets sent;

[0098] Step 4: Use the first time period parameter and the second time period parameter to obtain a preset time period, wherein the preset time period is obtained by the following formula:

[0099]

[0100] Wherein, T represents the preset time period; T 01Represents the first time period parameter; T 02 Represents the second time period parameter; W f and W b They respectively represent the weight value corresponding to the heartbeat packet sending frequency and the weight value corresponding to the signal strength of the terminal device.

[0101] The working principle of the above technical solution is as follows: the first influencing parameter includes the heartbeat packet sending frequency, network delay duration, network fluctuation tolerance duration and the corresponding change amplitude of the heartbeat packet sending frequency, and the above parameters reflect the basic performance and stability of the network. The second influencing parameter includes the network packet loss rate and signal strength, and the above parameters further consider the network quality and the ability of the terminal device to receive signals.

[0102] The heartbeat packet sending frequency and its changes, network delay duration, network fluctuation tolerance duration and compensation coefficient (t) are used to calculate the time period parameters based on network delay and fluctuation through complex formulas. The compensation coefficient (t) is adjusted according to the average, median and maximum values ​​of the network delay duration to cope with network fluctuations. The second time period parameters are calculated through a formula by comprehensively considering the packet loss rate, signal strength and the average value of the network delay duration. The packet loss rate weight (k) and signal strength threshold (By) are specially introduced here to reflect the impact of different network conditions on the time interval.

[0103] The first time period parameter and the second time period parameter are combined with their respective corresponding weights (Wf and Wb) to obtain the final preset time period through weighted summation. This method takes into account both network delay and fluctuation, as well as the impact of packet loss rate and signal strength.

[0104] The technical effect of the above technical solution is: by dynamically adjusting the time interval for sending heartbeat packets, it is possible to reduce unnecessary network communication overhead and improve overall communication efficiency while ensuring communication stability. The solution can automatically adjust the preset time period according to changes in the network environment and terminal device status, thereby enhancing the system's ability to adapt to network changes. Reduce communication interruptions or delays caused by network problems and improve the user experience during use. By comprehensively considering a variety of network parameters, the network status can be more accurately assessed, and the heartbeat packet sending strategy can be adjusted accordingly, which helps to improve the overall stability and reliability of the system. The solution provides flexible parameter configuration and calculation methods, which can be adjusted and optimized according to different application scenarios and requirements, and has high flexibility and scalability.
