METHOD AND APPARATUS FOR SERVICE PROCESSING IN A DUAL CARD TERMINAL DEVICE - Patent application

Abstract

An embodiment of the present application provides a method and apparatus for service processing in a dual card terminal device. The terminal device includes a first card and a second card, where the first card supports an SA network and the second card supports an LTE network. When the terminal device uses the second card to perform a voice service, if the terminal device receives a data service request that requires the first card for implementation, the terminal device can search for a cell corresponding to the first band. The cell corresponding to the first band is a cell accessed by the first card before the first card enters an idle state. Therefore, when the terminal device finds a cell corresponding to the first band and loads a radio frequency path for the first card into the cell corresponding to the first band, the terminal device does not implement a radio frequency path loading procedure for the second card, so that the voice service of the terminal device is not interrupted. In this way, the terminal device can implement both the data service of the first card and the voice service of the second card, enabling even more usage scenarios for the terminal device.

[0034] For the purpose of clearly describing the technical solutions in the embodiments of the present application, terms such as "first" and "second" in the embodiments of the present application are used to distinguish between the same or similar items having substantially the same function or purpose. For example, "first chip" and "second chip" are only intended to distinguish different chips, and are not intended to limit their order. Those skilled in the art can understand that terms such as "first" and "second" do not limit the number or execution order. In addition, terms such as "first" and "second" do not indicate clear distinctions.

[0035] It should be noted that in the embodiments of the present application, terms such as "example" or "for example" are used to indicate an example, illustration, or explanation. Any embodiment or design solution described in the present application as "example" or "for example" should not be construed as preferred or advantageous over other embodiments or design solutions. Rather, terms such as "example" or "for example" are intended to present related concepts in a concrete manner.

[0036] In the embodiments of the present application, "at least one" means one or more, and "multiple" means two or more. The term "and / or" describes the association relationship between the associated objects and indicates that three relationships can exist. For example, "A and / or B" can represent the cases of "A only", "both A and B", and "B only", where A and B can be singular or plural. The character " / " generally indicates an "or" relationship between the associated objects. "At least one of the following items (objects)" or similar expressions means any combination of these items, including any combination of a single item (object) or multiple items (objects). For example, at least one of a, b, or c can refer to a, b, c, "a and b", "a and c", "b and c", or "a, b, and c", where a, b, and c can be singular or plural.

[0037] With the development of terminal technology, dual card terminal devices have been developed and put into use, which allows users to meet various requirements with the terminal devices.

[0038] However, when one card is connected to a standalone (SA) network and the other card is connected to a long term evolution (LTE) network, it is possible that the terminal device can satisfy the user's calling needs with one card but cannot satisfy the user's Internet access needs with the other card during a call, which limits the usage scenarios of the terminal device and provides the user with a poor experience when using the terminal device.

[0039] One card may be called a main card or SIM1 card, and the SIM1 card may be called a data card. The other card may be called an auxiliary card or SIM2 card, and the SIM2 card may be called a calling card. The fact that the terminal device cannot satisfy the user's Internet access needs by using the other card may be interpreted as an Internet lag occurring when the terminal device accesses the Internet by using the other card, thereby making it impossible for the user's Internet access needs to be satisfied. The user's Internet access needs may be the user's needs to open a web page and search for information.

[0040] The terminal device uses the SIM2 card to perform voice services based on voice over long-term evolution (VOLTE). The SIM2 card can operate in an LTE mode and support radio access technologies such as LTE and 3rd-Generation (3G). The SIM1 card can operate in an SA mode and support radio access technologies such as 5th generation mobile communication technology (5G) and 4th generation mobile communication technology (4G). The SIM2 card operating in an LTE mode can be interpreted as the SIM2 card supporting an LTE network. Similarly, the SIM1 card operating in an SA mode can be interpreted as the SIM1 card supporting an SA network.

[0041] For example, Figure 1 is a schematic diagram of another application scenario according to an embodiment of the present application. As shown in Figure 1, when a user needs to access the Internet while making a call using SIM2 card, the terminal device can know that the user's Internet access needs cannot be met by using SIM1 card. As a result, the user can see a reminder message on the terminal device as shown in Figure 1. The reminder message indicates "Network is disconnected. Please try again after the network is connected".

[0042] 1, it can be understood that after the call of SIM2 card is ended, the Internet access procedure of SIM1 card activated by the terminal device returns to normal, so that the Internet access needs of the user can be met. Or, it can be understood that when the voice service of SIM2 card is ended, the data service of SIM2 card returns to normal.

[0043] For example, FIG. 2 is a schematic diagram of a dual card service according to an embodiment of the present application. As shown in FIG. 2, when a user does not make a call or access the Internet by using a terminal device, that is, when the user is not using the terminal device, neither the SIM1 card nor the SIM2 card has a service, in which case the SIM1 card has no data service and the SIM2 card has no voice service. When a user makes a call using the SIM2 card of the terminal device, the SIM2 card has a voice service and the SIM1 card has no data service. When a user makes a call using the SIM2 card, the SIM2 card has a voice service, and when the user needs to access the Internet during a call, the terminal device can trigger the SIM1 card. However, the terminal device cannot implement a data service after triggering the SIM1 card, and as a result, the user's Internet access needs cannot be met. After the user's call is ended, the SIM2 card has no voice service, and the SIM1 card activated by the terminal device has a data service, so that the user's Internet access needs can be met. The voice service may be interpreted as the user's calling service, and the data service may be interpreted as the user's Internet service.

[0044] It can be understood that the services of the SIM1 card and the SIM2 card of the terminal device during the call are analyzed in FIG. 2, and the status of the SIM1 card and the SIM2 card of the terminal device during the call can also be analyzed.

[0045] For example, Figure 3 is a schematic diagram of a dual card status according to an embodiment of the present application. As shown in Figure 3, when a user is not making a call or accessing the Internet by using a terminal device, both SIM1 card and SIM2 card are in an idle state. When a user is making a call using SIM2 card, if the user does not need to access the Internet, SIM2 card is in a connected state and SIM1 card is in an idle state. During a call using the user's SIM2 card, SIM2 card remains in a connected state, and when the user needs to access the Internet during a call, the terminal device can trigger SIM1 card. However, triggering SIM1 card by the terminal device cannot cause SIM1 card to switch from an idle state to a connected state, so SIM1 card fails to switch from an idle state to a connected state and remains in an idle state, which cannot meet the user's Internet access needs. After the user's call is ended, the SIM2 card enters an idle state, so that the SIM1 card triggered by the terminal device can switch from the idle state to a connected state to meet the user's Internet access needs.

[0046] When the SIM2 card of the terminal device is in a connected state, the terminal device has established a link to both the base station and the core network, and when data arrives in the network, the data can be sent directly to the terminal device. The terminal device can also send data to the base station and the core network, so that the SIM2 card of the terminal device can perform voice services. When the SIM2 card of the terminal device is in an idle state, there is no link between the terminal device and the base station and the core network, and if data needs to be sent, a new link needs to be established between the terminal device and the base station and the core network. The terminal device can receive data, but does not send data to the base station or the core network. In this case, the SIM2 card of the terminal device does not have a voice service. For the description of the case where the SIM1 card is in an idle or connected state, reference can be made to the corresponding description of the SIM2 card. Details will not be repeated here again.

[0047] Based on the above, the reason why the Internet access cannot be performed by using the SIM1 card when the SIM2 card of the terminal device is making a call is further analyzed in the embodiment of the present application as the SIM2 card switches from an idle state to a connected state when the user uses the SIM2 card of the terminal device to make a call. In this case, the terminal device needs to perform a network discovery procedure for the SIM2 card. The network discovery procedure is to find a connectable state for the SIM2 card. frequency The terminal device then uses the frequency It is possible to implement a radio frequency path loading procedure for the SIM2 card based on the above, whereby the terminal device can load the SIM2 card by using the loaded radio frequency path. frequencyIn this way, the terminal device can meet the calling needs of the user by using the SIM2 card.

[0048] When a user needs to access the Internet during a call, after triggering the SIM1 card, the terminal device needs to switch the SIM1 card from an idle state to a connected state. When the SIM1 card switches from an idle state to a connected state, the terminal device needs to perform a network discovery procedure for the SIM1 card, which makes the terminal device perform a radio frequency path loading procedure for the SIM1 card. The radio frequency path loading procedures for the SIM1 card and the SIM2 card of the terminal device are synchronous, or in other words, the SIM1 card and the SIM2 card of the terminal device use a group form in the radio frequency path loading procedure. Therefore, even if the radio frequency path loading procedures of the SIM1 card and the SIM2 card do not collide, the terminal device again performs the radio frequency path loading procedure for the SIM2 card, and then the call service of the SIM2 card is temporarily interrupted due to the radio frequency path loading procedure of the SIM2 card.

[0049] It can be understood that a network discovery procedure exists during the switching of SIM1 card from idle state to connected state. The network discovery procedure can be intra-frequency network discovery or inter-frequency network discovery. In the case of inter-frequency network discovery, the terminal device needs to reload the radio frequency path for SIM1 card, and at the same time reload the radio frequency path for the auxiliary card, and temporarily suspend the call of SIM2 card. The specific contents of intra-frequency network discovery and inter-frequency network discovery are described in the following embodiments. Details are not described here.

[0050] Some chips have limited functions, and a terminal device using such chips does not support Internet access using the SIM1 card during a call using the SIM2 card. In other words, if a user needs to access the Internet during a call, the terminal device does not perform a network discovery procedure for the SIM1 card, and therefore the terminal device does not perform a path loading procedure for the SIM1 card. In this case, the terminal device also does not perform a radio frequency path loading procedure for the SIM2 card, and therefore the call service of the SIM2 card of the terminal device is not interrupted. As a result, when a user is making a call using the SIM2 card of the terminal device, the user is not able to access the Internet using the SIM1 card of the terminal device.

[0051] For some platforms, due to limitations of their software architecture, they do not allow the network discovery procedure for SIM1 card to prevent interruption of the voice service of SIM2 card, making it impossible for SIM1 card to switch from the idle state to the connected state to implement data services. The connected state can also be called the service state.

[0052] If the terminal device is located in the same cell before performing the voice service and after completing the voice service by using the SIM2 card of the terminal device, the connection availability for the SIM2 card of the terminal device is frequencyIt can be seen that the SIM2 card remains unchanged. In this way, the terminal device does not need to perform a network discovery procedure or a radio frequency path loading procedure for the SIM2 card. If the terminal device is located in a different cell before performing a voice service and after completing the voice service by using the SIM2 card of the terminal device, the terminal device needs to perform a network discovery procedure and a radio frequency path loading procedure for the SIM2 card.

[0053] In relation to the above-mentioned reasons, for example, Figure 4 is a schematic diagram of path loading according to an embodiment of the present application. As shown in Figure 4, when the SIM1 card enters a connected state from an idle state at a first time point, the SIM2 card is in a connected state, so the terminal device does not perform a network discovery procedure for the SIM1 card, and therefore the terminal device does not perform a path loading procedure for the SIM1 card. As shown in Figure 4, the terminal device does not perform a receive (RX) path loading procedure for the SIM1 card, causing the SIM1 card to fail to switch from an idle state to a connected state. When the SIM1 card switches from an idle state to a connected state at a second time point, the SIM2 card is in an idle state, so the terminal device can perform a network discovery procedure for the SIM1 card, and therefore the terminal device performs a path loading procedure for the SIM1 card. As shown in Fig. 4, the terminal device executes a receiving path and a transmitting (TX) path loading procedure for the SIM1 card, so that the SIM1 card successfully switches from an idle state to a connected state, and the terminal device uses the SIM1 card to satisfy the user's Internet access needs. The terminal device also executes a radio frequency path loading procedure for the SIM2 card at a second time point, specifically, the terminal device executes a receiving path loading procedure for the SIM2 card, as shown in Fig. 4. However, the SIM2 card is in an idle state, in other words, the call of the SIM2 card has been completed, so the radio frequency path loading procedure executed by the terminal device for the SIM2 card does not affect the call quality.

[0054] In view of this, an embodiment of the present application provides a method for service processing in a dual card terminal device. The terminal device includes a first card and a second card, the first card supports an SA network, and the second card supports an LTE network. When the terminal device uses the second card to perform a voice service, if the terminal device receives a data service request that requires the first card for implementation, the terminal device uses the first card to perform the data service request. frequency It is possible to search for the cell that corresponds to the first frequency The cell corresponding to is the cell accessed by the first card before the first card enters the idle state. frequency Find the cell that corresponds to the first frequency When loading the radio frequency path for the first card into the cell corresponding to the first card, the terminal device does not perform the radio frequency path loading procedure for the second card, so that the voice service of the terminal device is not interrupted. In this way, the terminal device can implement both the data service of the first card and the voice service of the second card, enabling even more usage scenarios for the terminal device.

[0055] It can be understood that the method in this embodiment of the present application is a method that allows both data service and voice service to be performed simultaneously. With this method, the restriction of network discovery is broken through, so that a user can use one card to make a call and another card to access data, or in other words, a user can use one card to make a call and another card to access the Internet. In addition, with the method in this embodiment of the present application, the impact of network discovery on a call is also minimized.

[0056] For example, Figure 5 is a schematic flowchart of a method for service processing in a dual card terminal device according to an embodiment of the present application. In this embodiment of the present application, the first subscriber card is the aforementioned SIM1 card or the first card, and the second subscriber card is the aforementioned SIM2 card or the second card. As shown in Figure 5, the method may include the following steps:

[0057] S501: A terminal device triggers a data service request for a first subscriber card.

[0058] In this embodiment of the present application, the first subscriber card is in an idle state. When the terminal device detects the user's Internet access needs, for example, when the user opens an application (APP) of the terminal device, if the terminal device allows the APP to access the Internet, the terminal device can trigger a data service request for the first subscriber card by identifying the APP information, and further makes the terminal device use the first subscriber card to satisfy the user's Internet access needs. The APP information can include the name of the APP, etc., and the data service request can be interpreted as the user's Internet access request.

[0059] S502: The terminal device determines whether the second subscriber card runs a voice service.

[0060] In this embodiment of the present application, if the terminal device determines that the second subscriber card runs a voice service, the terminal device executes S504. If the terminal device determines that the second subscriber card does not run a voice service, the terminal device executes S503.

[0061] S503: The terminal device implements the data service of the first subscriber card.

[0062] In this embodiment of the present application, since the terminal device determines that the second subscriber card does not perform voice services, the terminal device can satisfy the user's Internet access needs by using the first subscriber card, so that after triggering a data service request for the first subscriber card, the terminal device can implement the data service of the first subscriber card.

[0063] When the terminal device determines that the second subscriber card is performing a voice service, if the terminal device needs to access the Internet by using the first subscriber card, the terminal device can perform an intra-frequency cell preferential discovery procedure for the first subscriber card, so that the terminal device does not need to reload the radio frequency path for the second subscriber card, and the voice service of the second subscriber card is not interrupted. The terminal device performs inter-frequency network discovery only in the case of intra-frequency cell disconnection. In addition, when performing inter-frequency network discovery, the terminal device can preferentially search for a dual-receive dual-card combination to reduce interruption to the call of the second subscriber card, in which case it takes about 1 ms to load the radio frequency path for the second subscriber card after the terminal device performs inter-frequency network discovery. For cases other than the dual-receive dual-card combination, it takes about 10 ms to load the radio frequency path for the second subscriber card after the terminal device performs inter-frequency network discovery. The specific contents are described in the steps below, and are not described in detail here.

[0064] S504: First frequency , and determines whether the terminal device has found a cell corresponding to .

[0065] In this embodiment of the present application, the first frequency The cell corresponding to is the cell accessed by the first subscriber card before the first subscriber card enters the idle state. Therefore, frequency If the terminal device is unable to find a cell corresponding to the first frequency If the terminal device finds a cell corresponding to the first frequency The failure of the terminal device to find a cell corresponding to may be interpreted as an intra-frequency disconnection.

[0066] 1. frequency The process of searching for a cell corresponding to the first subscriber card by the terminal device can be interpreted as an intra-frequency network discovery procedure of the terminal device. For example, FIG. 6 is a schematic diagram of intra-frequency network discovery according to an embodiment of the present application. As shown in FIG. 6, when the first subscriber card switches from an idle state to a connected state at a third time point, the terminal device searches for a cell corresponding to the first subscriber card by the terminal device. frequency After finding the cell corresponding to the first subscriber card, the terminal device performs an intra-frequency network discovery procedure for the first subscriber card. frequency The terminal device can load the radio frequency path for the first subscriber card into the cell corresponding to the first subscriber card. As shown in FIG. 6, the terminal device performs a receiving path and a transmitting path loading procedure for the first subscriber card. frequency The process of loading a radio frequency path for the first subscriber card by the terminal device into a cell corresponding to the first subscriber card does not affect the voice service of the second subscriber card, so that the terminal device does not need to reload the radio frequency path for the second subscriber card.

[0067] S505: The terminal device performs a first data service of the first subscriber card. frequency The radio frequency path for the first subscriber card is loaded into the cell corresponding to the first subscriber card.

[0068] In this embodiment of the present application, the first frequency The cells corresponding to the first frequency band may be interpreted as intra-frequency cells as described above. frequency The terminal device loads the radio frequency path for the first subscriber card into the cell corresponding to the first subscriber card, and loads the parameters of the components in the radio frequency path for the first subscriber card into the cell corresponding to the first subscriber card. frequency For example, the terminal device may adjust parameters of an amplifier, a filter, etc., so that the terminal device can obtain a first reception by using a radio frequency path whose parameters have been adjusted. frequency After being connected to the first subscriber card, the terminal device can implement the data service of the first subscriber card to meet the user's Internet access needs, and the voice service of the second subscriber card is not affected when the terminal device is implementing the data service of the first subscriber card.

[0069] S506: The terminal device connects to a second subscriber card to execute a voice service of the second subscriber card. frequency Determine.

[0070] In this embodiment of the present application, the phone module in the terminal device provides functions such as voice, messaging, SIM card management, etc. Therefore, when providing the voice service of the second subscriber card by using the phone module, the terminal device uses the phone module to connect to the second subscriber card to perform the voice service of the second subscriber card. frequency It is possible to determine

[0071] S507: The terminal device frequency The second in the combination frequency The third one that matches frequency Determine.

[0072] In this embodiment of the present application, the first frequency The combination is for dual receive-dual SIM dual standby (DR-DSDS). frequency It can be interpreted as a combination, the first frequency The combination is connected to execute the data service of the first subscriber card. frequency , and a second subscriber card connected to execute voice services. frequency For example, the first frequency If the combination contains [a,b], then the second frequency If b, the terminal device frequency Determine as a.

[0073] 1. frequency It can be understood that the specific content of the combination can be set based on the actual application scenario, which is not limited in this embodiment of the present application.

[0074] S508: Third frequency , and determines whether the terminal device has found a cell corresponding to .

[0075] In this embodiment of the present application, the third frequency If the terminal device finds a cell corresponding to the third cell, the terminal device executes S509. frequency If the terminal device is unable to find a cell corresponding to , the terminal device executes S510.

[0076] Third frequencyThe fact that the terminal device has found a cell corresponding to the first subscriber card and the second subscriber card can be interpreted as the first subscriber card and the second subscriber card being a dual-receive dual-card combination. frequency The terminal device's failure to find a cell corresponding to can be interpreted as the first subscriber card and the second subscriber card being not a dual receive dual card combination.

[0077] S509: The terminal device receives a third data service request from the first subscriber card to implement the data service of the first subscriber card. frequency The radio frequency path for the first subscriber card is loaded into the cell corresponding to the first subscriber card.

[0078] In this embodiment of the present application, the third frequency When the terminal device is loading the radio frequency path for the first subscriber card to the cell corresponding to the first subscriber card, the terminal device also reloads the radio frequency path for the second subscriber card. However, the time to reload the radio frequency path for the second subscriber card is relatively short, for example, it takes 1 ms to load the radio frequency path for the second subscriber card. Therefore, even if the user's ongoing call is interrupted, the user cannot perceive the interruption of the ongoing call, and the call of the second subscriber card can be resumed immediately. In addition, this also enables the user to access the Internet by using the first subscriber card.

[0079] The terminal device is a third frequency For specific content about loading the radio frequency path for the first subscriber card into the cell corresponding to the first subscriber card to implement the data service of the first subscriber card, reference can be made to the corresponding description of S505. Details will not be repeated here again.

[0080] Third frequency The process of searching for a cell corresponding to the first subscriber card by the terminal device can be interpreted as an inter-frequency network discovery procedure of the terminal device. For example, FIG. 7 is a schematic diagram of inter-frequency network discovery according to an embodiment of the present application. As shown in FIG. 7, when the first subscriber card switches from an idle state to a connected state at the fourth time point, the terminal device searches for a cell corresponding to the first subscriber card by the terminal device. frequency From the combination, the second frequency The third one that matches frequency Since the terminal device has determined the third frequency It is possible to search for the cell that corresponds to the third frequency After finding the cell corresponding to the third frequency In the embodiment, the terminal device performs a receiving path and a transmitting path loading procedure for the first subscriber card. As shown in FIG. 7, the terminal device performs a receiving path and a transmitting path loading procedure for the second subscriber card. In addition, the terminal device also needs to reload the radio frequency path for the second subscriber card. As shown in FIG. 7, the terminal device performs a receiving path and a transmitting path loading procedure for the second subscriber card. Even if the terminal device reloads the radio frequency path for the second subscriber card, it takes a relatively short time for the terminal device to perform such loading. In addition, since the terminal device does not need to perform a network discovery procedure for the second subscriber card, it may take less time to resume the voice service of the second subscriber card.

[0081] S510: The terminal device is connectable frequency Determine whether a cell corresponding to has been found.

[0082] In this embodiment of the present application, frequencyIf it is determined that the cell corresponding to the first subscriber card is not found, the terminal device executes S501 to S508, whereby the terminal device repeats the above process until the terminal device is able to implement the data service for the first subscriber card. frequency If the terminal device determines that a cell corresponding to has been found, the terminal device executes S511.

[0083] Connectable frequency Available when the terminal device searches N times for a cell corresponding to frequency If the terminal device finds a cell corresponding to within N times, the terminal device is able to connect. frequency It can be understood that the radio frequency path for the first subscriber card is loaded into the cell corresponding to the first subscriber card. frequency If the terminal device is unable to find a cell corresponding to the first card within N times, the terminal device will not implement data service using the first card, where N is a positive integer equal to or greater than 1.

[0084] S511: The terminal device can be connected to implement a data service of a first subscriber card. frequency The radio frequency path for the first subscriber card is loaded into the cell corresponding to the first subscriber card.

[0085] In this embodiment of the present application, the third frequency Since the terminal device is unable to find a cell corresponding to the cell number, the terminal device must continue with the network discovery procedure. frequency After finding the cell corresponding to frequency In addition, the terminal device also needs to perform a network discovery procedure for the second subscriber card. frequency After finding the cell corresponding to the found frequencyIt is possible to reload the radio frequency path for the second subscriber card to the cell corresponding to the first subscriber card. It takes a relatively short time, for example 10 ms, for the terminal device to perform a network discovery procedure to load the radio frequency path for the second subscriber card. Therefore, even if the user's ongoing call is interrupted, the user cannot perceive the interruption of the ongoing call, and the call of the second subscriber card can be resumed immediately. Therefore, the first subscriber card of the terminal device can meet the Internet access needs of the user, and the second subscriber card of the terminal device can also meet the call needs of the user.

[0086] Connectable frequency The process of searching for a cell corresponding to the frequency band by the terminal device can be interpreted as an inter-frequency network discovery procedure of the terminal device. For example, FIG. 8 is another schematic diagram of inter-frequency network discovery according to an embodiment of the present application. As shown in FIG. 8, when the first subscriber card switches from an idle state to a connected state at the fifth time point, the terminal device can connect to the frequency band. frequency Therefore, we have found the cell that corresponds to frequency In the case where the terminal device is connected to the cell corresponding to the first subscriber card, the terminal device can load the radio frequency path for the first subscriber card into the cell corresponding to the first subscriber card. As shown in FIG. 8, the terminal device performs a receiving path and a transmitting path loading procedure for the first subscriber card. In addition, the terminal device also needs to perform a network discovery procedure and a radio frequency path loading procedure for the second subscriber card. As shown in FIG. 8, the terminal device performs a receiving path and a transmitting path loading procedure for the second subscriber card.

[0087] The terminal device is available for connection. frequencyFor specific content about loading the radio frequency path for the first subscriber card into the cell corresponding to the first subscriber card to implement the data service of the first subscriber card, reference can be made to the corresponding description of S505. Details will not be repeated here again.

[0088] In relation to the above, it should be noted that generally, if the terminal device does not receive a real-time transport protocol (RTP) voice packet within 20s, the terminal device will release the call, so that the voice service is not performed for the second subscriber card of the terminal device. Since 1ms is <20s and 10ms is <20s, the voice packet of the second subscriber card of the terminal device is not released according to the method shown in FIG. 6. Therefore, the terminal device satisfies the user's Internet access needs by using the first subscriber card, and satisfies the user's call needs by using the second subscriber card. Although the medium access control (MAC) layer is responsible for scheduling and sending the voice packet to the terminal device every 20ms, the maximum number of retransmissions is not reached within 1ms, so the voice packet will not be lost, but instead the sending of the voice packet will be delayed, and in this case, the delay is too short to be perceived by the user. In addition, there is no dual card scenario in the MOS test, so the method in the embodiment of the present application does not affect the MOS test.

[0089] In relation to the above, it can be understood that for some platforms, due to the limitations of the software architecture of these platforms, these platforms do not allow the network discovery procedure for the SIM1 card to prevent the interruption of the voice service of the SIM2 card, making it impossible for the SIM1 card to enter the connected state from the idle state to implement the data service. With the method provided in the embodiments of the present application, some platforms can be optimized, so that on these platforms, the data service of the SIM1 card can be implemented while the voice service of the SIM2 card is implemented.
