The following describes in detail the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems by embodiments and with reference to the drawings. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a first flowchart illustrating a network connection method according to an embodiment of the present disclosure, where as shown in fig. 2, the network connection method includes the following steps:
step 201: a terminal determines that a target area supports a CA mode in a first communication network, wherein the target area is covered by the first communication network and a second communication network; the terminal supports a dual connectivity mode.
In the embodiment of the present application, the terminal is in a dual connectivity mode, and in the dual connectivity mode, the terminal can communicate with both a first base station (a base station in a first communication network) and a second base station (a base station in a second communication network). In an optional implementation manner, the first base station is a primary base station, and the second base station is a secondary base station, where the secondary base station is mainly responsible for transmitting data, the primary base station is mainly responsible for transmitting signaling, and the terminal, the first base station and the second base station form a dual connectivity architecture, referring to fig. 1.
Fig. 3 is a structural diagram of a communication module of a terminal in a dual connectivity mode, and as shown in fig. 3, in order to implement simultaneous communication with two base stations (corresponding to two communication networks), the terminal needs to have two sets of communication modules, where the two sets of communication modules correspond to the two base stations respectively. The first modem module (modem) and the first radio frequency path (including the first radio frequency circuit and the first radio frequency antenna) form a first set of communication modules, and the first set of communication modules corresponds to the first base station. A second modem module (modem) and a second radio frequency path (including a second radio frequency circuit and a second radio frequency antenna) form a second set of communication modules, which correspond to a second base station. In one example, the second modem is a 5G modem, the first modem is a 4G modem, the second radio frequency circuitry is 5G RF, and the first radio frequency circuitry is 4G RF. In the dual connection mode, the first communication module and the second communication module operate simultaneously.
In this embodiment, the first communication network and the second communication network may be different types of networks or the same type of network. In an optional embodiment of the present application, the first communication network is an LTE network (i.e., a 4G network), and the second communication network is an NR network (i.e., a 5G network).
In the embodiment of the present application, the CA mode refers to: by jointly scheduling and using resources on multiple Component Carriers (CCs), a communication network can support a larger bandwidth, thereby enabling a higher system peak rate. Taking the first communication network as an LTE network as an example, the CA mode in the first communication network may also be referred to as a 4G + mode.
In an optional embodiment of the present application, if the terminal detects, in the target area, that a duration in which the first communication network is in the CA mode is greater than or equal to a target duration, it is determined that the target area supports the CA mode in the first communication network.
Here, the target time period may be, but is not limited to, determined by any one of the following:
the method I comprises the following steps: and the terminal obtains the setting operation of the user, wherein the setting operation is used for setting the target duration.
The second method comprises the following steps: and the terminal manufacturer sets the target duration in the terminal system.
In one example, referring to fig. 4,1, a terminal monitors that LTE is continuously camped on 4G +; 2. the terminal judges whether the duration time on the 4G + is greater than or equal to the target duration time, if so, the following step 3 is executed; 3. and after the terminal enters the area covered by the 4G +, the terminal is not connected with the NR network or disconnected with the NR network. Here, it should be noted that the area covered by 4G + is also the area covered by the NR network.
Step 202: and if the terminal is positioned in the target area, the terminal is disconnected from the second communication network or the second communication network.
In this embodiment of the application, the terminal may determine one or more target areas supporting the CA mode in the first communication network through step 201. For example, the terminal may determine that area 1, area 2, and area 3 support the CA mode in the first communication network. After that, the terminal determines how to connect to the network according to the location where the terminal is located, which is described in detail below.
Situation one
And under the condition that the terminal is connected with the first communication network and the second communication network, if the terminal is in the target area, the terminal is disconnected with the second communication network. Under the condition, the terminal uses the CA mode (such as 4G +) under the first communication network to realize surfing the internet and disconnects the second communication network (such as NR network), thereby achieving the purpose of saving the energy consumption of the terminal.
Case two
And under the condition that the terminal is connected with the first communication network, if the terminal is in the target area, the terminal is not connected with the second communication network. Under the condition, the terminal uses the CA mode (such as 4G +) under the first communication network to realize internet surfing and can not be connected with the second communication network (such as NR network), thereby achieving the purpose of saving the energy consumption of the terminal.
In an optional embodiment of the present application, if the terminal turns on a switch, the terminal determines whether the target area supports a CA mode in the first communication network. When the method is specifically implemented, 1) the terminal judges whether to start a change-over switch or not; 2) And if the switch is turned on, determining whether the target area supports the CA mode in the first communication network.
In another optional implementation manner of the present application, if the terminal turns on the switch and the terminal is in the screen-off state, the terminal determines whether the target area supports the CA mode in the first communication network. When the method is specifically implemented, 1) the terminal judges whether to start a change-over switch or not; 2) If the switch is turned on, further judging whether the screen is in a screen-off state; 3) And if the target area is in the screen-off state, determining whether the target area supports the CA mode in the first communication network.
In the above solution, the switch is configured to control switching between a first communication network and the second communication network. In one example, the switch is a 4G/5G switch.
In the embodiment of the application, if the terminal determines that the target area supports the CA mode in the first communication network, the terminal stops measuring the second communication network in the target area, so as to achieve the purpose of saving terminal energy consumption.
In the embodiment of the present application, taking the second communication network as an NR network as an example, the scheme involved in the above embodiments may be referred to as a scheme of "optimizing a 5G function" or a scheme of "suppressing a 5G function". In an optional embodiment, the above scheme of "optimizing 5G functions" may be implemented by turning on the intelligent 5G.
Referring to fig. 5, fig. 5 is a schematic diagram of the terminal turning on the smart 5G, where turning on the smart 5G means optimizing or suppressing the 5G function. As shown in fig. 5, the terminal opening intelligence 5G includes the following processes:
1. the terminal judges whether the operation of opening the intelligent 5G is received or not.
Here, the terminal displays a user interface including an option to start the smart 5G, and the user may trigger an operation to select the option corresponding to the smart 5G, thereby starting the smart 5G. Here, the operation by the user may be a touch operation, a key operation, a voice operation, a gesture operation, or the like.
2. And if the operation of opening the intelligent 5G is received, optimizing the 5G function.
Here, the optimization of the 5G function includes at least: the 5G transmission rate of the terminal is limited to save power consumption of the terminal.
3. If the control instruction for opening the 5G function is not received, the 5G function is not optimized.
In an application scene, the terminal detects the temperature of the terminal; and under the condition that the temperature of the terminal is more than or equal to a target threshold, the terminal starts intelligent 5G, so that the 5G function is inhibited.
Illustratively, the temperature of the terminal may be embodied by the temperature of some hardware of the terminal or the average temperature of some several hardware, such as the temperature of a processor, the temperature of a memory, etc.
In an optional embodiment, the terminal turns off the smart 5G when the temperature of the terminal is less than the target threshold.
