For a specific implementation of the operation of determining whether a current network traffic demand can be met by a first network, embodiments of the present invention provide the following three examples:
first, the step of determining whether the current network traffic demand can be met by the first network comprises: and if the duration of the terminal in the idle state reaches a first preset duration, determining that the current network flow demand can be met through the first network.

Second, the step of determining whether the current network traffic demand can be met by the first network comprises: and if the average value of the data traffic of the terminal in the second preset time is smaller than the first threshold, determining that the current network traffic demand can be met through the first network.
Under the condition, before the control terminal is disconnected from the second network, the terminal capability is updated, the tracking area is started to update the TAU, and the updated terminal capability is reported to the network side; and informing the network side that the terminal does not transmit data on the air interface NR module any more, so that the network side does not schedule data on the air interface NR module any more, and when the data flow on the NR module is zero, closing the NR module (controlling the terminal to be disconnected from the second network).
Third, the step of determining whether the current network traffic demand can be met by the first network comprises: and if the average value of the data traffic of the terminal in a third preset time is smaller than a second threshold value and the number of times of converting the air interface inactive state into the connection state is smaller than a third threshold value, determining that the current network traffic demand can be met through the first network.
In this case, after the control terminal disconnects from the second network (turns off the NR module), the terminal capability is updated, and the tracking area update TAU is initiated, and the updated terminal capability is reported to the network side.
In the embodiment of the present invention, the first network may be a long term evolution LTE network, and the second network may be an air interface NR network.
Specifically, the step of disconnecting the connection between the control terminal and the second network includes: when the data flow on the NR module is zero, the NR module is turned off.
In order to synchronize with the network side in time, in this embodiment of the present invention, before or after the control terminal disconnects from the second network, the network connection method further includes: updating the terminal capability, initiating a tracking area to update TAU, and reporting the updated terminal capability to a network side; wherein the updated terminal capabilities indicate that the terminal will no longer transmit data on the second network.
In order to provide a high-rate data channel and meet service requirements, in an embodiment of the present invention, the network connection method further includes: and when the terminal is only in a connection state with the first network, if the terminal is determined that the current network flow demand cannot be met through the first network, the terminal is controlled to open the connection with the second network and maintain the connection with the first network.

Specifically, the NR module may be turned on, the terminal capability is updated, the tracking area is started to update the TAU, and the updated terminal capability is reported to the network side; wherein the updated terminal capabilities indicate that the terminal will begin transmitting data on the second network.
Further, the network connection method further includes: and when the terminal is only in a connection state with the first network and the mean value of the data traffic of the terminal in a fourth preset time period is determined to be greater than or equal to a fourth threshold, determining that the current network traffic demand can not be met through the first network.
In the following, the network connection method provided by the embodiment of the present invention is further described, where the first network takes LTE as an example, and the second network takes NR as an example.
In view of the above technical problems, an embodiment of the present invention provides a network connection method, which mainly reports, when LTE is used for terminal service traffic and service requirements can be met, terminal capabilities (LTE: available, 5G: disable) to a network side, and if the network side finds that the terminal 5G is disabled, data is not scheduled on a 5G NR module, so that the NR module is turned off when NR traffic is zero, and a single LTE state is entered to achieve the purpose of reducing terminal power consumption. When the terminal traffic reaches a preset threshold, an NR module of the terminal is opened, the terminal enters an LTE and NR dual-connection state, and simultaneously, the terminal state (LTE: enable 5G: enable) is reported to a network side, a high-speed data channel is provided, and the service requirement is met.
That is, for the NSA networking mode of the 5G network, the terminal adopts a dual connection mode, when the LTE and NR radio frequency modules of the terminal are in a state of working simultaneously, the terminal may be in a state of high power consumption, and when the terminal service has a low demand for data traffic and the LTE single mode can meet the demand, the terminal update capability (LTE: enable 5G: disable) is reported to the network, the network side finds that the 5G is in a disable state and is not scheduling air interface resources, and when the data traffic on the 5G NR module is zero, the terminal closes the terminal NR module. And when the terminal service is in the requirement of high rate, the terminal opens the NR module, reports the updated UE module capability (LTE: enable 5G: enable) to the network side, and enters a double-connection state.
The network side can store the module state (LTE: enable or disable, 5G: enable or disable) of the multimode terminal (the terminal supporting the first network and the second network), and the terminal is synchronized with the network side in time according to the opening and closing state of the NR module.
The network connection method provided by the embodiment of the present invention is illustrated below.
In an example, a terminal in a NR and LTE dual-connection state turns off an NR module, and enters an LTE single-mode state:
the method includes that a terminal is in an idle state, a Timer _ idle is started, when the Timer _ idle is overtime, the terminal is still in the idle state, an NR module is closed, and the terminal reports an updated UE capability (LTE: enable, 5G: disable) to a network side, as shown in fig. 2 specifically, the method includes:

step 25: judging whether the Timer _ idle is overtime or not, if yes, entering the step 26, and if not, returning to the step 24;
step 26: the terminal does not transmit data during the Timer _ idle period, the terminal closes the NR module and reports the updated terminal capability (LTE: enable, 5G: disable) to the network side; then step 29 is entered;
step 27: judging whether the terminal is in a connection state, if so, entering a step 28; if not, go to step 29;

Example two: the terminal in the NR and LTE double-connection state closes the NR module and enters the LTE single-mode state:
the terminal is in a connected state, when the data flow is smaller than a threshold value Thresh _ low, a Timer _ connection _ low is started, if the average data flow (the average data flow in the time length of the Timer) is smaller than Thresh _ low after timeout, the terminal reports the UE capability (LTE: early, 5G: disable) to the network side, the network side finds that the terminal NR module is in a disable state, the network does not schedule data on the NR module, and when the NR flow is zero, the terminal closes the NR module. As shown in fig. 3, the method includes:
step 31: starting;
step 32: judging whether the terminal is in a double-connection state, if so, entering a step 33, and if not, entering a step 310;
step 33: the terminal starts a Timer _ connection _ low;
step 34: the terminal starts to count the average data flow;
step 35: judging whether the Timer _ connection _ low is overtime or not, if yes, entering step 36, and if not, continuing to execute step 35;
step 36: judging whether the average data flow during the Timer _ connection _ low timing period of the Timer is smaller than Thresh _ low (can be a preset value) or not, if so, entering a step 37, and if not, entering a step 310;
step 37: the terminal reports the updated UE capability (LTE: enable, 5G: disable) to the network side;
step 38: the network side discovers that the terminal 5G NR module is in a disable state, and then data are not scheduled on the 5G NR module;
step 39: when the data flow of the terminal on the 5G NR module is zero, the terminal closes the 5G NR module;
step 310: and (6) ending.
In the third embodiment, when the data traffic exceeds the threshold, the NR terminal in the LTE single mode transitions to the NR and LTE dual-connection functional state:
when the terminal is in a connected state, when the data flow exceeds a threshold value Thresh _ up, a Timer _ connection _ up is started, and when the Timer _ connection _ up is overtime, the average data flow (the average data flow in the time length of the Timer) exceeds Thresh _ up, the terminal opens an NR module, and the terminal reports the updated UE capability (LTE: enable, 5G: enable). As shown in fig. 4, the method includes:
step 41: starting;
step 42: judging whether the terminal is in a single connection state, if so, entering a step 43, and if not, entering a step 49;
step 43: the terminal starts a Timer _ connection _ up;
step 44: the terminal starts to count the average data flow;
step 45: judging whether the Timer _ connection _ up is overtime or not, if yes, entering the step 46, and if not, continuing to execute the step 45;
step 46: judging whether the average data flow (the average data flow in the Timer _ connection _ up timing period) is greater than or equal to Thresh _ up (can be a preset value), if so, entering step 47, and if not, entering step 49;
step 47: the terminal opens the 5G NR module;
and 48: the terminal initiates reporting of UE capability updating (LTE: enable, 5G: enable) to the network side;
step 49: and (6) ending.
In a fourth example, when the terminal is in the NR inactive state, the terminal closes the NR module and enters the LTE single standby state:
when the terminal is in an Inactive state (5G newly introduced state, Inactive state, air interface release, but context of the air interface is reserved), starting a timer Inactive _ timer, counting the number of times that the terminal is switched to a connection state and the average value of data flow during a non-overtime period, and when the Inactive _ timer is overtime, judging whether the counted average data flow is lower than a preset data flow threshold or not and whether the number of times that the terminal is activated to the connection state is lower than an activation number threshold or not. If the number of the terminal nodes is less than the threshold, the terminal closes the NR module and initiates TAU to update and report the terminal capability (LTE: early 5G: disable) to the network side. As shown in fig. 5, the method includes:
step 51: starting;
step 52: when the terminal is in an Inactive state, starting a timer Inactive _ timer;
step 53: judging whether the timer inactive _ timer is overtime, if not, entering step 54, and if so, entering step 55;
step 54: during the period that the inactive _ timer of the timer is not overtime, counting the number of times Time _ active of terminal activation and calculating the Average data flow Average _ DataRate _ active in the whole data transmission duration; returning to step 53;
the whole data transmission duration may refer to a duration from a time point when data starts to be transmitted to a statistical time point, may also be a duration of a timer, and may also be a duration from when the terminal enters an inactive state to when the timer ends, and the like, which is not specifically limited herein.
Step 55: judging whether the Time _ active is smaller than the threshold of the activation times and the Average _ DataRate _ active is smaller than the preset data flow threshold; if not, returning to the step 52, if yes, entering a step 56;
step 56: the terminal closes the 5G NR module, simultaneously initiates TAU update to report the terminal capability (LTE: eanble, 5G: disable) to the network side, and puts all services in the LTE module;
and 57: and (6) ending.
As can be seen from the above, the solution provided in the embodiment of the present invention supports NR and LTE dual connectivity terminals, and can determine whether to turn off the NR module, enter the LTE module, and enter the power saving state according to the traffic transmission data flow; the problem of terminal waste power consumption of supporting NR and LTE double connection in the prior art is well solved.

The implementation embodiments of the network connection method are all applicable to the embodiment of the computer-readable storage medium, and the same technical effect can be achieved.
It should be noted that many of the functional components described in this specification are referred to as modules/sub-modules in order to more particularly emphasize their implementation independence.
In embodiments of the invention, the modules/sub-modules may be implemented in software for execution by various types of processors. An identified module of executable code may, for instance, comprise one or more physical or logical blocks of computer instructions which may, for instance, be constructed as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together, but may comprise disparate instructions stored in different bits which, when joined logically together, comprise the module and achieve the stated purpose for the module.
Indeed, a module of executable code may be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Likewise, operational data may be identified within the modules and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations including over different storage devices, and may exist, at least partially, merely as electronic signals on a system or network.
When a module can be implemented by software, considering the level of existing hardware technology, a module implemented by software may build a corresponding hardware circuit to implement a corresponding function, without considering cost, and the hardware circuit may include a conventional Very Large Scale Integration (VLSI) circuit or a gate array and an existing semiconductor such as a logic chip, a transistor, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices or the like.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
