[0002] In communication technology, a terminal can obtain a multicast / broadcast service (MBS). For example, a terminal can obtain an MBS through a corresponding radio frequency circuit. However, a terminal may have multiple radio frequency circuits, but how the terminal selects which radio frequency circuit to obtain the MBS still needs further study. Summary of the invention

[0003] The embodiments of the present application provide a data transmission method and device, which can quickly select which radio frequency circuit among the radio frequency circuits of multiple card slots to obtain the MBS of an application.

[0005] Based on the method provided in the first aspect, when the terminal is provided with multiple card slots, the terminal can quickly select which RF circuit among the RF circuits of the multiple card slots to obtain the MBS of the application, thereby reducing the user's manual selection of which RF circuit to obtain the MBS, improving the user experience and increasing the convenience of use.

By implementing this possible implementation, it is detailed in which specific dual-card scenarios are used to select the radio frequency circuit in the first card slot in the turned-on state to obtain the MBS of the application, which is conducive to a clearer understanding of which dual-card scenarios the present application is applicable to.

[0040] It should be noted that the embodiments of the present application can be applied to various communication systems, as long as there is an entity in the communication system that needs to send information and another entity that needs to receive the information. Figure 1 The communication system architecture or scenario in the embodiment of the present application is only an exemplary implementation method. The communication system architecture or scenario in the embodiment of the present application includes but is not limited to the above communication system architecture or scenario.

[0041] To facilitate understanding of the embodiments of the present application, the relevant names or terms involved in the present application are explained below.

[0042] 1. User Card

[0043] The user card can be a subscriber identity module (SIM) card, or a universal subscriber identity module (USIM) card, an embedded SIM card (eSIM) card or other types of user cards.

[0044] 2. Card Slot

[0045] The card slot is used to connect the user card. The user card can be connected to and separated from the terminal by inserting the card slot or pulling it out of the card slot. The terminal can be provided with multiple card slots. The terminal interacts with the network through the user card to realize functions such as calls and data communications. Exemplarily, each card slot can correspond to a card tray for placing the user card. The user card can be inserted into the card slot to fix the user card on the terminal. In a possible embodiment, the card tray corresponding to the card slot can have a space for placing the user card.

[0046] In a possible embodiment, the card slot refers to a slot or space on the terminal that accommodates the card tray. Figure 2 As shown, the terminal has a first card slot 210 and a second card slot 220, and the card trays corresponding to the two are different. The first card slot 210 corresponds to the card tray A, which can be inserted into the first card slot 210, and the card tray A is configured with a space a for placing a user card. The second card slot 220 corresponds to the card tray B, which can be inserted into the second card slot 220, and the card tray B is configured with a space b for placing a user card. For example, Figure 3 As shown, the terminal has a first card slot 210 and a second card slot 220, and the card trays corresponding to the two are the same and both correspond to the card tray C. The card tray C can be inserted into the first card slot 210 and the second card slot 220. In addition, the card tray C is configured with a space c1 and a space c2 for placing a user card.

[0047] It should be pointed out that Figure 2 and Figure 3 The number of the middle card slots is merely exemplary and should not be considered as a specific limitation of the present application.

[0048] 3. Dual SIM dual standby (DSDS)

[0049] Dual SIM dual standby can also be called dual SIM dual standby single call. For example, when the user card is a SIM card, the two SIM cards inserted in the terminal supporting the DSDS mode can be in standby state at the same time, but when the terminal uses one SIM card to make a call, the other SIM card is in an unavailable state. If the terminal is the calling party, a call includes starting a call, calling, call establishment and call; if the terminal is the called party, a call includes receiving a call, call establishment and call.

[0050] 4. Dual SIM dual active (DSDA)

[0051] Dual SIM dual access can also be called dual SIM dual standby dual access. For example, when the user card is a SIM card, the terminal supporting the DSDA mode has concurrent capabilities for the two SIM cards, so when the terminal makes a call through one SIM card, the other SIM card is in an available state, so that the terminal in the DSDA mode has the ability to use the other SIM card to access the Internet during a call with one SIM card (referred to as DSDA capability).

[0052] 5. Data Card

[0053] A data card refers to a user card that currently uses data traffic to access the Internet.

[0054] The following is an introduction to the data transmission method provided in the embodiment of the present application.

[0055] See also Figure 4 , Figure 4 It is a flow chart of a data transmission method provided in an embodiment of the present application, and the data transmission method includes step S401. Figure 4 The method shown may be performed by a terminal, or the subject may be a chip in the terminal. Figure 4 The method shown may also be performed by other types of products, and those skilled in the art may further expand the method based on the contents disclosed in the specification. Figure 4 The method execution subject shown is a terminal.

[0056] S401: The radio frequency circuit in the first card slot is in an on state, and the MBS of the application is received through the radio frequency circuit in the first card slot.

[0057] The terminal may be provided with a plurality of card slots, and the plurality of card slots include the first card slot. An application is installed on the terminal.

[0058] Optionally, the plurality of card slots further includes a second card slot, that is, the terminal is provided with a first card slot and a second card slot. Among them, the plurality can be understood as two or more than two. The number of card slots in this application is not limited to two, but can be more than two. For the convenience of description, two card slots, such as the first card slot and the second card slot, are used as an example for introduction, which should not be regarded as a limitation of this application.

[0059] The following three solutions are divided into the following to explain the specific scenario of the terminal receiving the MBS of the application program through the radio frequency circuit in the first card slot.

[0060] 1. No card (or no user card is inserted) or card disabled (or all user cards inserted in the card slot are in disabled state) scenario.

[0061] Among them, there may be the following four situations in the card-free or card-banned scenario:

[0062] Case 1: No user card is inserted into the first card slot and the second card slot.

[0063] Case 2: The user cards inserted into the first card slot and the second card slot are both in a disabled state.

[0064] Case 3: No user card is inserted into the first card slot and the user card inserted into the second card slot is in a disabled state.

[0065] Case 4: The user card inserted in the first card slot is in a disabled state and no user card is inserted in the second card slot.

[0066] Generally speaking, when there is no card in the first card slot and the second card slot, or both the card slots are in a card-disabled state, the terminal receives the MBS of the application program through the radio frequency circuit in the first card slot.

[0067] Optionally, when the RF circuit in the second card slot is in an on state, the MBS of the application is received through the RF circuit in the first card slot based on a predefined order. The predefined order includes the priority order of the first card slot and the second card slot, and the priority of the first card slot is higher than the priority of the second card slot. By implementing this possible implementation, it is further introduced that the MBS of the application is received through the RF circuit in the first card slot based on the predefined order only when the RF circuit in the second card slot is also in an on state.

[0068] The predefined order may be the default priority order of the first card slot and the second card slot of the terminal, the order in which the RF circuit in the first card slot and the RF circuit in the second card slot are turned on, and the like.

[0069] For example, assuming that the predefined order is the order in which the RF circuit in the first card slot and the RF circuit in the second card slot are turned on, the RF circuit in the first card slot is turned on first, and then the RF circuit in the second card slot is turned on. Therefore, the terminal receives the MBS of the application through the RF circuit in the first card slot.

[0070] In a possible embodiment, the terminal can search for a first cell associated with the network identifier and frequency information corresponding to the application through the radio frequency circuit in the first card slot based on the network identifier and frequency information corresponding to the application. When the first cell associated with the network identifier and frequency information corresponding to the application is found, the terminal receives the MBS of the application through the radio frequency circuit in the first card slot that is in an on state based on the first cell.

[0071] The network identifier corresponding to the application may be an identifier of a public land mobile network (PLMN).

[0072] Exemplarily, the network identifier and frequency information corresponding to the application can be stored in the application as a configuration file. The terminal can update the configuration file by updating the application, that is, updating the network identifier and frequency information corresponding to the application.

[0073] As another example, the network identifier and frequency information corresponding to the application program may also be obtained and updated from the server corresponding to the application program.

[0074] Optionally, when the first cell associated with the network identifier and frequency information corresponding to the application is not found, the terminal searches for a second cell associated with the network identifier corresponding to the application, and the frequency information corresponding to the second cell is different from the frequency information corresponding to the application. When searching for the second cell associated with the network identifier corresponding to the application, the frequency information corresponding to the application is updated to the frequency information corresponding to the second cell.

[0075] In a possible embodiment, when the first cell associated with the network identifier and frequency information corresponding to the application is not found, the terminal may perform a network search through the radio frequency circuit in the first card slot that is turned on to receive the broadcast message.

[0076] Among them, the broadcast message may be system information block 1 (system information block type 1, SIB1). SIB1 may include system information block 20 (system information block type 20, SIB20), and SIB20 is used to carry control information related to MBS. SIB20 may also carry a network identification list and frequency information, and the network identification list includes at least one network identification. It can be understood that the cell corresponding to the network identification list and frequency information carried by SIB20 is a cell that supports MBS. The terminal may select the network identification list and frequency information carried by SIB20 in the searched SIB1 as the network identification and frequency information corresponding to the application, that is, update the network identification and frequency information corresponding to the application to the network identification list and frequency information carried by SIB20.

[0077] Optionally, when there are multiple network identifiers in the network identifier list carried by SIB20, the terminal can select any network identifier in the network identifier list carried by SIB20 to update the network identifier corresponding to the application, and use the frequency information corresponding to the selected network identifier to update the frequency information corresponding to the application.

[0078] 2. Single card (or only one card slot has a user card inserted and is enabled) scenario.

[0079] Among them, the single card scenario may have the following four situations:

[0080] Case 1: The user card inserted in the first card slot supports the MBS of the application and no user card is inserted in the second card slot.

[0081] Case 2: The user card inserted in the first card slot supports the MBS of the application and the user card inserted in the second card slot is in a disabled state.

[0082] Case 3: The terminal supports dual-SIM dual-standby, the user card inserted in the first card slot does not support the MBS of the application, and no SIM is inserted in the second card slot or the user card inserted in the second card slot is in disabled state.

[0083] Case 4: The terminal supports dual-SIM dual-pass, no user card is inserted into the first card slot or the user card inserted into the first card slot is in disabled state, and a user card is inserted into the second card slot.

[0084] Optionally, a broadcast message is received in the first cell by a user card inserted in the first card slot, and the broadcast message includes at least one network identifier. Among them, the at least one network identifier includes a network identifier corresponding to the application, and the user card inserted in the first card slot supports the MBS of the application. On the contrary, in the case where the at least one network identifier does not include the network identifier corresponding to the application, the user card inserted in the first card slot does not support the MBS of the application. By implementing this possible implementation, how to judge whether the user card supports the MBS of the application is described in detail, that is, judging whether the user card supports the MBS of the application according to whether the broadcast message received by the user card inserted in the first card slot in the cell where it resides includes the network identifier corresponding to the application.

[0085] The broadcast message may be SIB1. SIB1 may include a network identifier list, and the network identifier list includes at least one network identifier. When the network identifier list includes the network identifier corresponding to the application, the user card inserted in the first card slot supports the MBS of the application. When the network identifier list does not include the network identifier corresponding to the application, the user card inserted in the first card slot does not support the MBS of the application.

[0086] Optionally, before receiving the MBS of the application through the radio frequency circuit in the first card slot, the method further includes: when the terminal supports dual-SIM dual-standby, outputting first prompt information, the first prompt information is used to prompt the user to set the user card inserted in the first card slot to a disabled state. By implementing this possible implementation, the user can clearly understand which user card inserted in the card slot will be set to a disabled state, thereby improving the user experience.

[0087] The first prompt information may include but is not limited to text prompt information, image prompt information, animation prompt information, etc. For example, the first prompt information may be text prompt information: "Please set the user card inserted in the first card slot to a disabled state."

[0088] Exemplarily, the user may input first instruction information according to the first prompt information, and the first instruction information is used to instruct the terminal to set the user card inserted in the first card slot to a disabled state. The terminal sets the user card inserted in the first card slot to a disabled state only after acquiring the first instruction information.

[0089] As another example, the terminal may also set the user card inserted in the first card slot to a disabled state when outputting the first prompt information. The first prompt information may also be used to prompt the user that the user card inserted in the first card slot is set to a disabled state. For example, the first prompt information may be "the user card inserted in the first card slot is already in a disabled state".

[0090] Optionally, when the terminal supports dual-SIM dual-pass, the user card inserted in the first card slot does not support the MBS of the application, and the user card inserted in the second card slot is in a disabled state, or when the terminal supports dual-SIM dual-pass, the user card inserted in the first card slot does not support the MBS of the application, and no user card is inserted in the second card slot, the terminal receives the MBS of the application through the radio frequency circuit in the second card slot.

[0091] 3. Dual-card (or two card slots with user cards inserted and both in enabled state) scenario.

[0092] Among them, the dual-SIM scenario may have the following four situations:

[0093] Case 1: The user card inserted in the first card slot supports the MBS of the application and the user card inserted in the second card slot does not support the MBS of the application.

[0094] Case 2: Both the user card inserted in the first card slot and the user card inserted in the second card slot support the MBS of the application program, and the user card inserted in the first card slot is a data card.

[0095] Case 3: The terminal supports dual-SIM dual-standby, and the user card inserted in the first card slot and the user card inserted in the second card slot do not support the MBS of the application.

[0096] Case 4: The terminal supports dual-SIM dual-pass, the user card inserted in the first card slot and the user card inserted in the second card slot do not support the MBS of the application, and the user card inserted in the first card slot is a non-data card.

[0097] Optionally, before receiving the MBS of the application through the radio frequency circuit in the first card slot, the method further includes: when the terminal supports dual-SIM dual-standby, outputting second prompt information, the second prompt information is used to prompt the user to set both the user card inserted in the first card slot and the user card inserted in the second card slot to a disabled state. By implementing this possible implementation, the user can clearly understand which user cards inserted in which card slots will be set to a disabled state, thereby improving the user experience.

[0098] The second prompt information may include but is not limited to text prompt information, image prompt information, animation prompt information, etc. For example, the second prompt information may be text prompt information: "Please set both the user card inserted in the first card slot and the user card inserted in the second card slot to disabled status."

[0099] Exemplarily, the user can input second indication information according to the second prompt information, and the second indication information is used to instruct the terminal to set both the user card inserted in the first card slot and the user card inserted in the second card slot to a disabled state. The terminal sets the user card inserted in the second card slot to a disabled state only after acquiring the second indication information.

[0100] As another example, the terminal may also have set both the user card inserted in the first card slot and the user card inserted in the second card slot to a disabled state when outputting the second prompt information. The second prompt information may also be used to prompt the user that both the user card inserted in the first card slot and the user card inserted in the second card slot are set to a disabled state. For example, the second prompt information may be "the user card inserted in the first card slot and the user card inserted in the second card slot are both in a disabled state."

[0101] Optionally, before receiving the MBS of the application through the radio frequency circuit in the first card slot, the method further includes: when the terminal supports dual-card dual-pass and the user card inserted in the first card slot is a non-data card, outputting a first prompt message, the first prompt message being used to prompt the user to set the user card inserted in the first card slot to a disabled state. That is, when the terminal supports dual-card dual-pass and both card slots are inserted with user cards, the terminal sets the non-data card to a disabled state, and then selects the radio frequency circuit in the card slot corresponding to the non-data card to receive the MBS. By implementing this possible implementation, the user can clearly understand under what circumstances the user card inserted in the card slot will be set to a disabled state when it is a non-data card, thereby improving the user experience.

[0102] Optionally, when both the user card inserted in the first card slot and the user card inserted in the second card slot support the MBS of the application and the user card inserted in the second card slot is a data card, or when the terminal supports dual-card dual-pass, both the user card inserted in the first card slot and the user card inserted in the second card slot support the MBS of the application, and the user card inserted in the second card slot is a non-data card, the terminal receives the MBS of the application through the radio frequency circuit in the second card slot. Wherein, when the terminal supports dual-card dual-pass, both the user card inserted in the first card slot and the user card inserted in the second card slot support the MBS of the application, and the user card inserted in the second card slot is a non-data card, the terminal sets the user card inserted in the second card slot to a disabled state.

[0103] Optionally, when the terminal supports dual-SIM dual standby and both the user card inserted in the first card slot and the user card inserted in the second card slot do not support the MBS of the application, the MBS of the application is received through the radio frequency circuit in the first card slot based on a predefined order. The predefined order includes a priority order of the first card slot and the second card slot, and the priority of the first card slot is higher than the priority of the second card slot.

[0104] Optionally, when the user card inserted in the first card slot supports the MBS of the application and the user card inserted in the second card slot does not support the MBS of the application, the terminal selects the user card inserted in the first card slot as a data card. When the user card inserted in the first card slot does not support the MBS of the application and the user card inserted in the second card slot supports the MBS of the application, the terminal selects the user card inserted in the second card slot as a data card. That is, when user cards are inserted in both card slots and only one user card inserted in the card slot supports MBS, the user card supporting MBS is selected as the data card.

[0105] It can be seen that based on Figure 4 According to the described method, when a terminal is provided with multiple card slots, the terminal can quickly select which RF circuit among the RF circuits of the multiple card slots to obtain the MBS of the application, thereby reducing the user's manual selection of which RF circuit to obtain the MBS, improving the user experience and the convenience of use.
