Detailed Description
The technical solutions of the present disclosure will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments of the present disclosure, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present disclosure without making any creative effort belong to the protection scope of the present disclosure. In addition, technical features involved in different embodiments of the present disclosure described below may be combined with each other as long as they do not conflict with each other.
In the related art, a DSDC (Dual-SIM-Dual-Call) terminal usually includes two independent radio frequency modules, so that one SIM (Subscriber Identity Module) card does not affect the other SIM card to browse the internet during a Call.
Meanwhile, thanks to the development of the VoLTE (Voice over LTE) technology and the 5G (fifth generation mobile communication technology), the same SIM card can realize simultaneous connection of data services for communication. For example, in a 4G network, the VoLTE function can implement that the same SIM card is connected to a data service while talking; for another example, when the current network where the 5G terminal resides is NSA (non-independent networking) and the core network allocates the 5G network, the same SIM card can connect data services while talking. Therefore, the DSDC terminal in the related art often determines the SIM card to which the data service is connected according to user selection.
However, the inventor of the present invention finds that a DSDC terminal in the related art is prone to call disconnection or disconnection of a data link during a call, which brings inconvenience to user experience. Through further research, it is found that, especially for a 5G terminal in an NSA networking mode, since a 4G and 5G public core network is required, when the same SIM card is used for communication and data service connection, the problem of data link interruption or call disconnection is very easy to occur, which causes great trouble to a user.
Based on the above-mentioned drawbacks in the related art, in a first aspect, the embodiments of the present disclosure provide a communication method for a dual-card terminal.
The dual card terminal may be the DSDC terminal, which may be any type of terminal device, such as a smart phone, a tablet computer, a wearable device, and the like, which is not limited by the present disclosure, and the communication method of the following embodiments of the present disclosure may be executed by a processor of the terminal. The dual card terminal includes a first radio frequency module and a second radio frequency module, where the first radio frequency module and the second radio frequency module are two independent radio frequency subsystems, and may include elements for providing radio frequency resources, such as a radio frequency transmitter, a radio frequency receiver, an antenna, and a power amplifier, which will be understood by those skilled in the art and will not be described in detail in this disclosure.
It should be noted that, the first radio frequency module and the second radio frequency module in the embodiments of the present disclosure may be the same radio frequency module, for example, both are 4G radio frequency modules; different rf modules may be used, for example, the first rf module is a 4G rf module, and the second rf module is a 5G rf module, which is not limited in this disclosure, and the "first rf module" and the "second rf module" are only used for the expressive distinction between the two rf modules, which is not limited in this respect. Meanwhile, hereinafter, for convenience of description, the two SIM cards of the dual card terminal are referred to as "SIM card 1" and "SIM card 2".
Fig. 1 illustrates some embodiments of the disclosed method, and as shown in fig. 1, in some embodiments, the disclosed communication method comprises:
s110, when the terminal is detected to be in the first communication connection, determining a user identity identification SIM card establishing the first communication connection as a first SIM card; the first communication connection is a call service related to the first SIM card and established through the first radio frequency module.
The dual-card terminal comprises two SIM card interfaces which are respectively used for communicating with the SIM card 1 and the SIM card 2, and the service state of the terminal can be obtained by monitoring the service state of the SIM card interfaces. In this step, the first communication connection means that the terminal is in a call service state, the radio frequency module for establishing the current call service is determined as the first radio frequency module, and the SIM card for establishing the current call service is determined as the first SIM card.
Specifically, when the terminal is detected to be in a call state, the SIM card in the current call state, that is, the first SIM card, can be determined by detecting the SIM card interface. In other words, the first SIM card refers to the SIM card in the current call state, which may be either SIM card 1 or SIM card 2.
In one example, when the SIM card 1 is in a call state, then the SIM card 1 is determined to be the first SIM card. In another example, when the SIM card 2 is in a call state, it is determined that the SIM card 2 is the first SIM card. It is understood that another SIM card other than the first SIM card is referred to as a second SIM card.
S120, establishing a second communication connection through a second radio frequency module; the second communication connection is data traffic associated with the second SIM card.
Specifically, when it is determined that the terminal is in the first communication connection, in order to avoid that the first SIM card is in the communication service and data service states at the same time, in this step, a complete data service link is established through the second radio frequency module and the second SIM card, so that when the first SIM card is in the communication service, the second SIM card is switched to implement the data service. In the following, details of how to implement the data service of the second SIM card are not described herein again.
In this way, according to the communication method in the embodiment of the present disclosure, when it is detected that the terminal is in the call state, it is determined that the SIM card in the current call state is the first SIM card, so that the data service is established by using the second radio frequency module through the second SIM card different from the first SIM card. The first SIM card is prevented from being in a call state and a data link state at the same time, the risk of call disconnection or data link interruption is reduced, and the internet surfing experience of a user in the call process is improved.
It is worth mentioning that at least one inventive concept of the communication method of the present disclosure lies in: and when the first SIM card is detected to be connected with the call service, switching the data service of the terminal to the second SIM card. Therefore, when switching the terminal data service, the following two scenarios are included: 1) and the terminal establishes a data service through the first SIM card before establishing a call service. 2) And the terminal establishes a data service through the second SIM card before establishing the call service.
In the foregoing step S120, in some embodiments, for both scenarios, an operation of establishing the second communication connection may be performed once, that is, when the terminal establishes the data service through the first SIM card before establishing the call service, and detects that the terminal is in the first communication connection, the data service of the first SIM card is switched to the second SIM card; and when the terminal establishes the data service through the second SIM card before establishing the call service and detects that the terminal is in the first communication connection, the operation of switching the data service of the second SIM card to the second SIM card is also performed once. The reliability of the system is ensured by redundant operations.
In other embodiments, the operation of establishing the second communication connection may be performed only for scenario 1), and the corresponding operation is not performed for scenario 2). Fig. 2 shows a flow of the communication method of the present embodiment, and as shown in fig. 2, the communication method of the present embodiment includes:
s210, when the terminal is detected to be in the first communication connection, determining that the SIM card for the user identity identification establishing the first communication connection is the first SIM card.
S220, judging whether the first SIM card establishes a data service with the second radio frequency module or not, if so, executing a step S230; if not, no action is executed.
And S230, establishing a second communication connection through the second radio frequency module.
Specifically, in step S210, the step S110 may be referred to, and will not be described herein again. After the first SIM card in the current call state is determined, whether the first SIM card establishes a data service with the second radio frequency module is judged. If yes, it indicates that the current first SIM card is in the call state and the data service connection state at the same time, step S230 is executed to switch the current data service to the second SIM card. If not, the first SIM card is not in the conversation state and the data service link state at the same time, and the action does not need to be executed.
For step S230, how to implement the data service of the second SIM card is described in detail below, which is not repeated herein.
As can be seen from the above, in the communication method of the present embodiment, before the second communication connection is established through the second radio frequency module, it is determined whether the current data service is established by the first SIM card, so that unnecessary redundant operations are reduced.
Some embodiments of establishing the second communication connection in the disclosed method are illustrated in fig. 3. As shown in fig. 3, in some embodiments, the disclosed methods comprise:
s310, deactivating the data service of the first SIM card.
And S320, activating the data service of the second SIM card so as to establish a second communication connection between the second radio frequency module and the second SIM card.
Specifically, when the second communication connection is established, the data service of the first SIM card is deactivated first, where the deactivation is to control the data link of the first SIM card to be disconnected. During the deactivation process, the following two scenarios are also included: 1) the terminal establishes a data service through the first SIM card before establishing a call service. 2) And the terminal establishes a data service through the second SIM card before establishing the call service.
In step S310, in an example, for the above two scenarios, an operation of deactivating the data service of the first SIM card may be performed once, that is, when the terminal establishes the data service through the first SIM card before establishing the call service, and detects that the terminal is in the first communication connection, the data service of the first SIM card is deactivated; and when the terminal establishes the data service through the second SIM card before establishing the call service and detects that the terminal is in the first communication connection, the data service of the first SIM card is also deactivated, and the reliability of the method is ensured through redundant operation. In another example, the operation of deactivating data traffic of the first SIM card may be performed only for scenario 1), and the corresponding operation is not performed for scenario 2). It will be understood by those skilled in the art that the details are not repeated herein.
In step S320, the data service of the second SIM card is specifically activated by controlling the second SIM card to establish a data link with the second radio frequency module, so as to establish the data service through the second SIM card and the second radio frequency module. The first SIM card is prevented from being in a call state and a data link state at the same time, the risk of call disconnection or data link interruption is reduced, and the internet surfing experience of a user in the call process is improved.
Fig. 4 shows a specific embodiment of the communication method of the present disclosure, which is further described below with reference to fig. 4.
In this embodiment, the dual-card terminal takes a 5G smart phone as an example, and the 5G smart phone is compatible with the 4G network at the same time, so the 5G smart phone often includes a 4G radio frequency module and a 5G radio frequency module. Meanwhile, the SIM card 1 and the SIM card 2 can switch and connect the 4G and 5G radio frequency modules to realize multiplexing of the 4G and 5G networks, that is, the SIM card 1 can switch and connect the 4G or 5G radio frequency module, and the SIM card 2 can also switch and connect the 4G or 5G radio frequency module. In this embodiment, the call service is a service established in a 4G network, and the data service is a service established in a 5G network, so that the first radio frequency module is a 4G radio frequency module, and the second radio frequency module is a 5G radio frequency module.
As shown in fig. 4, in this embodiment, the communication method of the present disclosure includes:
s410, when the terminal is detected to be in the first communication connection, determining that the SIM card for user identity identification establishing the first communication connection is the first SIM card.
Specifically, the dual-card mobile phone comprises two SIM card interfaces which are respectively used for communicating with the SIM card 1 and the SIM card 2, and can monitor the SIM card interfaces, obtain whether the current call service is the SIM card 1 or the SIM card 2 according to the monitored signals, and determine the SIM card establishing the current call service as the first SIM card.
In an example, if the mobile phone establishes a call service on the 4G network through the SIM card 1, the first communication connection is the call service established with the SIM card 1 through the 4G radio frequency module, so that the SIM card 1 is determined as the first SIM card.
S420, judging whether the first SIM card establishes a data service with the 5G radio frequency module, if so, executing the step S430. If not, no action is executed.
Specifically, it is determined whether the current data service state is the data service established by the first SIM card and the 5G radio frequency module, if yes, it indicates that the current first SIM card is in the call state and the data service connection state at the same time, and then step S430 is executed. If not, the first SIM card is not in the conversation state and the data service link state at the same time, and the action does not need to be executed.
S430, disconnecting the data link between the first SIM card and the 5G radio frequency module.
In one example, the activation and deactivation of data traffic includes: and controlling the SIM card to be in switching connection with the 4G or 5G radio frequency module, and establishing or disconnecting the data link of the connected radio frequency channel. In this step, the data link between the first SIM card and the 5G radio frequency module may be disconnected by switching the connection between the first SIM card and the 5G radio frequency module.
S440, establishing a data link between the second SIM card and the 5G radio frequency module so that the second SIM card establishes a data service through the 5G radio frequency module.
In an example, the process of activating the data service for the second SIM card is specifically to switch the connection between the first SIM card and the 5G radio frequency module to the connection between the second SIM card and the 5G radio frequency module, and establish a data link of a radio frequency path between the second SIM card and the 5G radio frequency module, so that the second SIM card establishes the data service through the 5G radio frequency module.
As can be seen from the above, in this embodiment, when the mobile phone is in a call service state, the data link of the first SIM card is disconnected, and the data link between the second SIM card and the 5G radio frequency module is activated, so that the 5G radio frequency module is used to establish a data service, thereby greatly improving the data traffic rate.
