Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
At present, in the requirement of the production cost of the mobile terminal device or the anti-interference capability of the device, the mobile terminal device is usually provided with only one antenna, for example, a dual-card dual-standby terminal device, so that two communication cards (card 1 and card 2) on the terminal device share one antenna to transmit and receive information, and therefore, the two communication cards are required to be closely coordinated.
However, as shown in fig. 1, the terminal device 101 communicates with the base station 102, and when the card 1 is a master card (data card) and Packet Service (PS) is in progress, for example, uploading a file and browsing a web page, the card 1 uses an antenna to perform information interaction with the base station 102. At this time, the user performs supplementary services on the card 2, such as call forwarding, number display, and when the call is limited, the card 2 is switched to a data card, and at this time, the card 2 uses an antenna to perform information interaction with the base station 102. However, since some services on the card 1 are not completely finished, the card 1 may reuse the antenna, that is, the connection with the base station 102 is re-initiated through the antenna, so that the card 2 cannot use the antenna, and the services on the card 2 are interrupted and cannot be normally performed.
Therefore, to solve the problems existing in the prior art, the present application proposes: in the prior art, after data card switching, the data card before switching still seizes an antenna to perform information interaction with the network side, so that service interruption on the switched data card is caused.
Fig. 2 is a flowchart of a communication card switching processing method according to an embodiment of the present application, and as shown in fig. 2, the method according to the embodiment may include:
s201, a communication card switching instruction is obtained.
The communication card switching instruction is used for indicating that a main communication card of the terminal equipment is switched from a first communication card to a second communication card.
In this embodiment, a terminal device is provided with two communication cards, namely, a first communication card (namely, card 1) and a second communication card (namely, card 2), where the card 1 is a data card and the card 2 is a non-data card, a user inputs a communication card switching instruction to the terminal device, for example, by operating a control for switching the data card on the terminal device, and the terminal device obtains the communication card switching instruction to switch the data card from the card 1 to the card 2, or when the user uses the card 2 on the terminal device to perform supplementary services, such as call forwarding, number display, and call restriction, that is, when the service performed by the user using the card 2 requires the card 2 to be the data card, the terminal device obtains the communication card switching instruction to switch the data card from the card 1 to the card 2, or when the user sets a data card switching condition of the terminal device in advance, for example, when the switching time arrives, the terminal device actively generates the communication card switching instruction to switch the data card from the card 1 to the card 2.
S202, responding to the communication card switching instruction, the terminal equipment disconnects the service of the first communication card communicating with the network side through the antenna of the terminal equipment, and establishes the communication connection of the second communication card with the network side through the antenna, so that the main communication card is switched from the first communication card to the second communication card.
In this embodiment, an Application Processor (AP) on the terminal device manages an application on the terminal device, so that the AP can acquire the application on the first communication card (card 1) that performs information interaction with the network side using an antenna. Therefore, after the terminal device obtains the communication card switching instruction, the AP on the terminal device can obtain the service of the current card 1 communicating with the network side through the antenna, and actively interrupt the service. Therefore, in the process of switching the card 2 into the data card, that is, performing the supplementary service on the card 2, no service on the card 1 performs information interaction with the network side through the antenna, thereby avoiding the problem that the service of the card 1 performs information interaction with the network side through the antenna in the process of performing the supplementary service on the card 2. After the interrupt card 1 interrupts the service of the communication between the card 1 and the network side through the antenna of the terminal device, the interrupt device establishes the communication connection between the card 2 and the network side through the antenna, that is, the service on the card 2 can perform information interaction with the network side through the antenna, thereby completing the switching of the main communication card (i.e., data card) from the card 1 to the card 2.
In this embodiment, the terminal device obtains the communication card switching instruction, responds to the communication card switching instruction before the second communication card is switched to the data card, disconnects the service of the first communication card communicating with the network side through the antenna of the terminal device, and then establishes the communication connection between the second communication card and the network side through the antenna, so as to complete the switching of the main communication card from the first communication card to the second communication card. The communication card switching instruction is used for indicating that a main communication card of the terminal equipment is switched from a first communication card to a second communication card. Therefore, before the second communication card is switched to the main communication card, the service communicated with the network side through the antenna on the first communication card is disconnected, so that the condition that the first communication card still occupies the antenna and the service on the second communication card is interrupted due to the fact that the link is re-established between the antenna and the network side after the switching of the main communication card is completed is avoided, the service on the second communication card can be smoothly completed, and user experience is improved.
Fig. 3 is a signaling flowchart of a communication card switching processing method according to an embodiment of the present application, and as shown in fig. 3, the method according to the embodiment may include:
s301, a communication card switching instruction is obtained.
In this embodiment, S201 may be referred to as a specific implementation manner of S301, which is not described herein again.
S302, the AP determines one or more first applications from a plurality of applications installed in the terminal device.
The first application program is an application program which uses the first communication card to communicate with the network side currently.
In this embodiment, the AP on the terminal device manages the application program on the terminal device, and therefore, the AP may acquire the application program on the first communication card (card 1) that performs information interaction with the network side using the antenna. Therefore, after the terminal device acquires the communication card switching instruction, the AP determines an application program, called a first application program, on a first communication card (card 1) of the terminal device, which is currently performing information interaction with the network side using an antenna.
S303, the Communication Processor (CP) obtains the second information of each first application.
The second information is used for indicating the network side to stop sending the information related to the first application program to the first communication card.
In this embodiment, after the AP determines that the application program currently using the antenna to perform information interaction with the network side on the first communication card (card 1) of the terminal device and disconnects the first application program, since the first application program is currently performing information interaction with the network side before, the network side has information related to the first application program to be sent to the first application program through the antenna of the card 1, and therefore, even if the first application program is disconnected, the network side still sends the information related to the first application program through the antenna of the card 1. Therefore, for each first application, the AP sends to the CP second information for instructing the network side to stop sending information related to the first application to the card 1. The second information includes, for example, a first application program and a flag bit RST, where the flag bit RST is used to indicate whether to end the first application program, and for example, when the RST is 1, the flag bit RST indicates to end the first application program; and when the RST is 0, indicating that the first application program is started.
S304, the CP sends the first information to the network side.
Wherein the first information is used for instructing the network side to stop sending information related to one or more first application programs to the first communication card
In this embodiment, after receiving the at least one piece of second information sent by the AP, the CP obtains the first information according to the at least one piece of second information, and sends the first information to the network side through the antenna. The first information is, for example, a TCP packet, where the TCP packet includes an identifier of at least one first application, and the flag bit RST of each first application is set to 1, which indicates that the first application has ended, so that the network side may be instructed by the first information to stop sending information related to one or more first applications to the card 1.
S305, the CP receives information which is sent by the network side to the first communication card and is related to the first application program through the antenna.
In this embodiment, in an actual use of the terminal device, after the CP sends the first information to the network side, if the network side has information related to the first application and needs to send the information to the terminal device, the network side still sends the information related to the first application to the terminal device, so that the CP receives the information related to the first application sent by the network side to the card 1.
S306, the CP discards the information related to the first application.
In this embodiment, after receiving the information related to the first application program sent to the card 1 by the network side through the antenna, the CP does not send the information related to the first application program to the corresponding first application program, but directly discards the information related to the first application program, so that the connection between the first application program and the network side through the antenna of the card 1 can be cut off.
S307, the CP sends the first information to the network side.
In this embodiment, after receiving the information related to the first application program, which is sent to the card 1 by the network side through the antenna, in order to avoid that the first information is not received by the network side or the first information is tampered during the sending process, the CP sends the first information to the network side again.
And S308, establishing communication connection between the second communication card and the network side through the antenna, and switching the main communication card from the first communication card to the second communication card.
In this embodiment, the AP switches the main communication card having card 1 to card 2, and thereafter, the card 2 is in communication connection with the network side through the antenna.
S309, the CP receives information related to the first application program, which is sent to the first communication card by the network side through the antenna.
In this embodiment, after the data card is switched from the card 1 to the card 2, if the network side has the information related to the first application and needs to send the information to the terminal device, the network side still sends the information related to the first application to the terminal device, and thus the CP still receives the information related to the first application sent by the network side to the card 1.
S310, information related to the first application program is discarded.
In this embodiment, after receiving the information related to the first application program sent to the card 1 by the network side through the antenna, the CP does not send the information related to the first application program to the corresponding first application program, but directly discards the information related to the first application program, so that the connection between the first application program and the network side through the antenna of the card 1 can be cut off.
S311, the AP sends information related to the second application program to the CP, wherein the information is required to be sent to the network side through the first communication card.
In this embodiment, before the main communication card is switched from the card 1 to the card 2, the first application program that uses the antenna to perform information interaction with the network side on the card 1 is completely ended, so as to avoid that the first application program still needs to use the antenna of the card 1 to perform information interaction with the network side. However, in the process of executing S303-S310, a new application (referred to as a second application) may exchange information with the network side using the antenna of the card 1, and at this time, the AP cannot actively end the second application, and therefore, the second application exchanges information with the network side using the antenna of the card 1, and therefore, the AP may transmit information related to the second application to the network side through the antenna of the card 1 to the CP, so that the CP transmits information related to the second application to the network side.
Resulting in the antenna being occupied by the card 1. Thus, the second application is received at the CP
S312, the CP discards the information related to the second application.
In this embodiment, the CP sends the information related to the second application to the network side, and sends the information related to the second application to the network side through the antenna of the card 1, so that the CP occupies the antenna of the terminal device, and the application on the card 2 cannot use the antenna. Therefore, after the CP receives the information related to the second application, which is transmitted by the AP and needs to be transmitted to the network side through the antenna of the card 1, the information related to the second application is discarded, so that the information related to the second application is not transmitted to the network side through the antenna of the card 1.
And S313, the terminal equipment uses the antenna of the second communication card to normally communicate with the network side.
In this embodiment, after the card 2 is switched to the main communication card, the application program on the terminal device cannot use the antenna of the card 1 to perform information interaction with the network side through the above operations, so that the ongoing supplementary service on the card 2 is normally communicated with the network side through the antenna of the card 2.
In this embodiment, the terminal device obtains a communication card switching instruction, the AP determines one or more first applications from a plurality of applications installed in the terminal device and sends second information of each first application to the CP, and the CP obtains the second information of each first application and sends the first information to the network side to end the first application, and switches the communication connection between the first communication card and the network side through the antenna. And after the switching of the main communication card is completed, after the CP receives the information which is sent by the network side to the first communication card and is related to the first application program, the information which is sent by the network side to the first communication card and is related to the first application program is discarded, so that the influence of the first application program on the service on the switched main communication card can be reduced. And after the AP sends the information related to the second application program to the network side through the first communication card, the CP discards the information related to the second application program and avoids the new application program from sending the information to the network side through the antenna of the first communication card, so that the occupation of the antenna by the service on the first communication card is reduced, the service on the second communication card can be smoothly carried out, and the user experience is improved.
