Background

A 5G New-generation New Radio (5G NR) is a next-generation mobile communication technology following Long Term Evolution (LTE), and supports higher rate, lower delay, and larger connection number, and network performance is greatly improved compared with LTE. Deployment of 5G networks requires consideration of coexistence and convergence with existing LTE wireless communication systems. According to the deployment relationship between the 5G and the LTE network, the third generation partnership project standard proposes two networking architectures, namely Non-dependent (NSA) and independent (SA).

With the continuous development of the access mode, the content actually included in each of the high-level access mode and the low-level access mode can also be set by a technician according to an actual situation, and the higher the theoretical data transmission rate is, the higher the access mode is. The optimal high-level access mode may be an access mode with the highest theoretical data transmission rate, or may be an access mode selected by a user in advance.

The exemplary embodiment of the present disclosure provides a communication control method, which is mainly used for a terminal with a 5G secondary card. The terminal with the 5G secondary card means that the terminal supports the secondary card to implement the 5G function, for example, the terminal supports the secondary card to perform 5G network connection, or the terminal supports the secondary card to perform 5G voice call. Therefore, the terminal is greatly improved in both data transmission speed and voice call quality. In addition, the 5G voice communication not only has shorter calling time delay, but also can enjoy high-speed 5G internet surfing while realizing high-definition communication.

In an exemplary embodiment of the present disclosure, the secondary card may be an electronic Module, such as a SIM (subscriber Identity Module) card, a USIM (universal subscriber Identity Module) card, and a UIM (User Identity Module) card, which can function to Identify a User. The secondary card is generally referred to as a primary card, which is a SIM card preset to operate in a high-level access mode among SIM cards of the mobile terminal, and the secondary card is a SIM card preset to operate in a low-level access mode among the SIM cards of the mobile terminal. In general, the number of the main card in the mobile terminal is only one, and the number of the sub-cards can be multiple. The types of the main card and the auxiliary card can be the same or different, and the operators of the main card and the auxiliary card can be the same or different. For convenience of description, the exemplary embodiments of the present disclosure are described by taking only the case where both the primary card and the secondary card are SIM cards as an example.

For a terminal with a 5G secondary card, the secondary card is also set as a SIM card operating in a high-level access mode. Only the sub-card is usually in a standby state, and in this state, the terminal still performs 5G network search or connection through the sub-card, which results in an increase in power consumption of the terminal and a corresponding increase in power consumption. The exemplary embodiment of the disclosure provides a communication control method aiming at the problem that the power consumption of the existing terminal with a 5G auxiliary card is large.

A communication control method according to an exemplary embodiment of the present disclosure is specifically described below with reference to fig. 2. As shown in fig. 2, the communication control method may include:

step S210, obtaining a secondary card working mode supported by the terminal; the auxiliary card working modes comprise a first working mode and a second working mode;

step S220, when the terminal supports the first working mode, if the current environment supports the 5G voice function, controlling the terminal to be connected to a 4G core network or a 5G core network;

when the terminal supports the first working mode, if the current environment does not support the 5G voice function, under the condition that an auxiliary card data network is required to be used, controlling the terminal to be connected to a 4G core network through a 5G base station and a 4G base station by utilizing the auxiliary card;

and when the terminal supports the second working mode, controlling the terminal to be connected to a 4G core network through a 4G base station and a 5G base station by using the secondary card under the condition that a secondary card data network is required to be used.

The communication control method achieves the following technical effects: according to the auxiliary card working mode supported by the terminal, whether the terminal has the requirement for 5G network connection or not can be preliminarily judged through the auxiliary card working mode. When the terminal supports the second working mode, the control terminal is connected to the 4G core network by using the auxiliary card only under the condition that the terminal needs to use the auxiliary card data network, and the 5G network connection is not needed under other conditions, so that the purpose of saving power consumption is achieved under the condition that data transmission is not influenced. In addition, when the terminal supports the first working mode, whether the current environment supports the 5G voice function or not can be judged, when the current environment supports the 5G voice function, it is indicated that the terminal can perform a 5G call through the secondary card, and at this time, the terminal can be controlled to be connected to a 4G core network or a 5G core network, so as to implement the 5G call function; and when the current environment does not support the 5G voice function, the terminal cannot carry out 5G conversation through the auxiliary card, at the moment, only under the condition that the auxiliary card data network is needed to be used, the control terminal is connected to the 4G core network through the 5G base station and the 4G base station by utilizing the auxiliary card, and under other conditions, the 5G network connection is not needed, so that the purpose of saving power consumption is achieved under the condition that data transmission is not influenced.

According to the communication control method provided by the exemplary embodiment of the disclosure, the communication mode of the terminal can be specifically determined according to the working mode of the auxiliary card and the current environment, and network connection is performed only under the condition that a 5G call needs to be performed or an auxiliary card data network needs to be used, so that the purpose of saving energy consumption is achieved, and the electric quantity consumption of the double-card double-5G terminal is reduced.

The following describes the implementation process of each step:

in step S210, obtaining a secondary card operating mode supported by the terminal; the auxiliary card working mode comprises a first working mode and a second working mode.

Firstly, after the terminal is started, the secondary card working mode supported by the terminal can be acquired and identified through the baseband chip. And then the baseband chip performs corresponding control operation on the terminal according to a pre-stored program based on the acquired auxiliary card working mode.

For a terminal such as a mobile phone, a baseband chip is a communication module in the mobile phone, and the most important function is to communicate with a base station of a mobile communication network to perform modulation, demodulation, coding and decoding on uplink and downlink wireless signals. In practical application, the starting mode of the sub-card working mode supported by the terminal is obtained, and the sub-card working mode supported by the terminal can be automatically obtained after the terminal is started; or the user starts the operation of obtaining the auxiliary card working mode supported by the terminal through an application program installed on the terminal. The manner of starting the acquisition is not particularly limited in the exemplary embodiments of the present disclosure.

In an alternative embodiment, the secondary card operating mode refers to a mode in which the terminal can access the network through the SIM card. The secondary card operating mode is related to the networking mode supported by the secondary card. Referring to fig. 3, two networking modes are currently used for the network: non-Stand alone mode (NSA) and Stand alone mode (SA). Wherein, under the non-independent networking mode, the 4G base station and the 5G base station of the current network are both accessed to the 4G core network; in the independent networking mode, the 5G base station is only accessed into the 5G core network.

In an alternative embodiment, as shown in fig. 4, only one of the second operation modes is an NSA mode, i.e. a non-independent networking mode. In the NSA mode, the terminal can access to the 4G core network through the 4G base station and the 5G base station by using the secondary card. The first operation mode may be other than the NSA-only mode, for example, a dual-mode operation mode including the independent networking mode SA and the dependent networking mode NSA, and an operation mode including only the independent networking mode SA. In the first working mode, the terminal can access to the 4G core network through the 4G base station and the 5G base station by using the secondary card, and can also access to the 5G core network through the 5G base station by using the secondary card. The independent networking mode SA and the dependent networking mode NSA both belong to a high-level access mode.

In practical application, the baseband chip may obtain all access modes supported by the secondary card in a full-band scanning manner, and then determine the working mode of the secondary card according to the access modes supported by the secondary card. Since each access mode that the secondary card can support corresponds to a frequency band supported by the network provided by the operator of the secondary card, the terminal may determine the frequency band supported by the network provided by the operator of the secondary card first, and then determine the high-level access mode supported by the secondary card, that is, the 5G access mode such as SA, NSA, and the like, according to the frequency band supported by the network.

In the present exemplary embodiment, step S220 performs different settings on the terminal based on different operation modes of the secondary card, i.e. the first operation mode and the second operation mode, and as shown in fig. 5, five cases of the settings are now described as follows:

in the first case: and after the terminal is started and the auxiliary card working mode supported by the terminal is obtained, matching judgment is carried out with the auxiliary card working mode stored in advance. And if the terminal supports the first working mode, namely the terminal supports a dual-mode working mode or the working mode of only an independent networking mode, judging whether the current environment supports the 5G voice function. If the current environment supports the 5G voice function, the terminal can be controlled to be connected to the 4G core network or the 5G core network at the moment when the current environment supports the 5G voice function and the terminal can carry out 5G voice call through the auxiliary card. When the terminal needs to perform 5G voice communication through the auxiliary card or receives paging information of the auxiliary card, the terminal can directly establish network connection with the 4G core network or the 5G core network through the 4G base station or the 5G base station by using the auxiliary card, and further realize the 5G voice communication function.

In an optional implementation manner, the determining whether the current environment supports the 5G voice function mainly refers to determining whether both the terminal and the network at the location of the terminal support the 5G voice function, and it may be determined that the current environment supports the 5G voice function only when the terminal and the network at the location of the terminal support the 5G voice function at the same time, and if one of the terminal and the network at the location of the terminal does not support the 5G voice function, the current environment does not support the 5G voice function.

The terminal supporting the 5G voice function means that the terminal can be connected with a 5G network, and a system capable of carrying out 5G conversation is arranged on the terminal. The location of the terminal may refer to an actual geographic location such as a latitude and longitude coordinate of the terminal, or may refer to a logical location such as a cell where the terminal is located. The terminal may determine its actual geographic location via a wireless positioning system or may determine its logical location via a base station. Whether the network at the location of the terminal supports the 5G voice function means that the location of the terminal can establish network connection with the 4G core network or the 5G core network through the 4G base station or the 5G base station.

In an optional implementation manner, after the first situation, that is, after the step of controlling the terminal to connect to the 4G core network or the 5G core network if the current environment supports the 5G voice function when the terminal supports the first operation mode, the communication control method further includes: and controlling the terminal to monitor a Physical Downlink Control Channel (PDCCH) or controlling the terminal to monitor the paging information of the auxiliary card of the network, so that the terminal can respond in time according to the allocation and scheduling of network resources in the standby state of the auxiliary card.

If the terminal receives the physical downlink control channel belonging to the terminal, the terminal may receive downlink data or send uplink data on the time-frequency resource indicated by the physical downlink control channel. If the terminal does not receive the physical downlink control channel belonging to the terminal, the terminal continues to perform the blind detection of the physical downlink control channel on the next subframe or on the subframe which accords with the monitoring period and the offset of the physical downlink control channel configured by the base station, so that the physical downlink control channel belonging to the terminal is received next time for data transmission.

The paging information of the auxiliary card is a calling request of the network to the auxiliary card, and after the terminal receives the paging information of the auxiliary card, the terminal can use the auxiliary card to answer the corresponding calling request, so that the 5G voice communication function can be entered.

In practical applications, there may be multiple monitoring manners for the terminal to wake up the secondary card function for scheduling information and paging information of network resources under a standby condition of the secondary card.

The communication control method provided by the exemplary embodiment of the present disclosure may control the terminal to connect to the 4G core network or the 5G core network through the secondary card when the terminal supports the first operating mode and the current environment supports the 5G voice function. When the terminal needs to perform a 5G voice call through the secondary card, or the terminal receives a physical downlink control channel belonging to the terminal, or the terminal receives paging information of the secondary card, the terminal may directly establish network connection with the 4G core network or the 5G core network through the 4G base station or the 5G base station by using the secondary card. And further, the 5G voice communication function is realized, the 5G auxiliary card function of the terminal is fully exerted, and the condition of power consumption waste is avoided.

In the second case: when the terminal supports the first working mode, namely the terminal supports the dual-mode working mode or the working mode of only the independent networking mode, if the current environment does not support the 5G voice function, the terminal cannot carry out the 5G voice call through the auxiliary card. Then, at this time, it is also necessary to determine whether the secondary card data network needs to be used, and only in the case that the secondary card data network needs to be used, the control terminal is connected to the 4G core network through the 5G base station and the 4G base station by using the secondary card. So that the terminal establishes network connection by using the auxiliary card, and the terminal can conveniently transmit data by using the auxiliary card. At this time, the working mode of the auxiliary card is a non-independent networking mode.

The above situation often occurs when a user is playing a game or surfing the internet using a terminal and the like requires data traffic. In this case, the terminal is by default carrying the traffic by the main card. If the auxiliary card receives the call information at the moment, when the user answers the call through the auxiliary card, the terminal stays in a mode of the auxiliary card bearing the service, and then the data transmission of the main card is interrupted; therefore, the situation that the user is stuck in the game or the network is disconnected can be caused when playing the game or surfing the internet.

In the exemplary embodiment, it is determined that the user needs to use the sub-card data network, for example, when the user needs to continue playing a game or surfing the internet using the terminal. At this time, the control terminal is connected with the network by using the auxiliary card, so that the situation that the game card is on or the network is disconnected can be avoided, and the control terminal is connected with the 4G core network through the 5G base station and the 4G base station simultaneously, so that the data transmission rate can be improved, and the user experience can be improved.

It should be noted here that, in a mobile terminal, only one SIM card can operate in the high-level access mode at the same time under normal conditions. Therefore, when the mobile terminal is switched to the auxiliary card working mode, the working mode of the main card can be switched to the preset access mode, wherein the preset access mode can be a low-level access mode such as 2G under the normal condition, and the main card is prevented from being disconnected while the power consumption is saved.

In the third case: when the terminal supports the first working mode, namely the terminal supports the dual-mode working mode or the working mode of only the independent networking mode, if the current environment does not support the 5G voice function, the terminal cannot carry out 5G voice call through the auxiliary card, and under the condition that the auxiliary card data network is not needed, the terminal is controlled to stop establishing auxiliary cell group connection by using the auxiliary card.

The cell is a basic unit serving the terminal user, and is a logical area emitted by an antenna on a base station. For a 5G network, cells include a 4G anchor Cell serving as a Master Cell Group (MCG) and a 5G Cell serving as a Secondary Cell Group (SCG), and the 5G Cell needs to establish a 5G network connection for a terminal through the 4G anchor Cell. The terminal is controlled to stop utilizing the auxiliary card to establish the auxiliary cell group connection, namely the terminal is prevented from utilizing the auxiliary card to establish the 5G network connection, so that the terminal is prevented from generating meaningless power consumption waste when the auxiliary card data network is not needed, and the purpose of saving energy is achieved.

Referring to fig. 6, when the 4G anchor cell receives the received power including the reference signal of the 5G cell from the terminal and determines that the received power meets the threshold value of the service availability, the 4G anchor cell will access the 5G cell together to provide the service for the terminal, that is, the dual connectivity in the NSA mode. At the moment, the 4G anchor point cell is responsible for receiving the control signaling of the 4G core network and forwarding the control signaling to the terminal and the 5G cell; and the 5G cell is responsible for shunting the data received from the 4G core network to the 4G cell, and the 4G anchor point cell and the 5G cell simultaneously transmit the data for the terminal.

It should be noted that, in addition to preventing the terminal from establishing the 5G network connection by using the secondary card by controlling the terminal to stop establishing the secondary cell group connection by using the secondary card, the terminal may also be prevented from establishing the 5G network connection by using the secondary card by closing a data network connection module of the secondary card, and the like. The mode for preventing the terminal from establishing the 5G network connection by using the secondary card in the exemplary embodiment of the disclosure may not be specifically limited, and any mode that can prevent the terminal from establishing the 5G network connection by using the secondary card falls within the protection scope of the present application.

In a fourth case: and when the terminal supports the second working mode, under the condition that a secondary card data network is required to be used, controlling the terminal to utilize the secondary card to connect to a 4G core network through a 4G base station and a 5G base station so that the terminal establishes network connection by utilizing the secondary card, and facilitating data transmission by utilizing the secondary card. At this time, the working mode of the auxiliary card is a non-independent networking mode.

The above situation is similar to that described in the second case, and when the user is playing a game or surfing the internet with the terminal and needs data traffic, the service is carried by the main card by default in the terminal. If the auxiliary card receives the call information at this time, when the user answers the call through the auxiliary card, the terminal stays in the auxiliary card service bearing mode, and at this time, the data transmission of the main card is interrupted, so that the user can have the situation of game card pause or network disconnection when playing games or surfing the internet.

In the exemplary embodiment, it is determined that the user needs to use the sub-card data network, for example, when the user needs to continue playing a game or surfing the internet using the terminal. At the moment, the control terminal is connected with the network by using the auxiliary card, so that the situation that the game is jammed or the network is disconnected can be avoided; and the 5G base station and the 4G base station are connected to the 4G core network at the same time, so that the data transmission rate can be improved, and the user experience is improved.

It should be noted here that, in a mobile terminal, only one SIM card can operate in the high-level access mode at the same time under normal conditions. Therefore, the mobile terminal can switch the working mode of the main card to the preset access mode while switching to the working mode of the auxiliary card. The preset access mode can be a low-level access mode such as 2G under the normal condition, so that the power consumption is saved, and the main card is prevented from being disconnected.

In the fifth case: and when the terminal supports the second working mode, under the condition that a secondary card data network is not needed, controlling the terminal to stop establishing secondary cell group connection by using the secondary card.

In the exemplary embodiment, the terminal is controlled to stop using the secondary card to establish the secondary cell group connection, so that the terminal can be prevented from establishing the 5G network connection using the secondary card, and therefore, when the secondary card data network is not needed, the terminal is prevented from generating meaningless power consumption waste, and the purpose of saving energy is achieved.

In an alternative embodiment, the step of controlling the terminal to stop establishing the secondary cell group connection by using the secondary card may include: and setting the double-connection link of the secondary card to be in a deactivation or pause state. The dual connection link is dual connection of LTE and NR, and dual connection of two wireless communication technologies can be realized. The double-connection link of the secondary card is set to be in a deactivation or pause state, so that the secondary card can be prevented from establishing secondary cell group connection, 5G network connection can be further prevented from being established by the secondary card, and under the condition that a secondary card data network is not needed, the power consumption of the terminal can be reduced, and the power consumption is reduced.

It should be noted that, in addition to controlling the terminal to stop establishing the secondary cell group connection by using the secondary card by setting the dual-connection link of the secondary card to be in the deactivated or suspended state, the secondary card may also be prevented from establishing the secondary cell group connection by directly setting the secondary cell group to be in the deactivated or suspended state, and the like, so as to prevent the terminal from establishing the 5G network connection by using the secondary card. The exemplary embodiment of the present disclosure may not specifically limit the manner for preventing the secondary card from establishing the secondary cell group connection, and any manner that can achieve the purpose of preventing the terminal secondary card from establishing the secondary cell group connection falls within the protection scope of the present application.
