[0062] The accompanying drawings illustrate specific embodiments of the invention, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0063] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

[0064] Existing mobile terminals require two sets of chips to achieve dual SIM dual standby. Each set includes a radio frequency (RF) chip and a baseband chip, each used to transmit data from one SIM card. Alternatively, the RF chip can have two channels, each used to transmit data from a different SIM card. Both solutions require multiple sets of chips or multi-channel RF chips in the mobile terminal, resulting in high hardware costs. Furthermore, when using multi-channel RF chips, mutual interference between the channels can occur.

[0065] Figure 1 This is a schematic diagram of a conventional dual-SIM dual-standby data communication method provided in an embodiment of the present invention, as shown below. Figure 1 As shown, when a mobile terminal has two user identification cards, two channels need to be established with the network side device when transmitting data.

[0066] In addition, some technologies use dual-receiver, single-transmitter video combined with a baseband chip to achieve dual SIM dual standby, but this requires frequent and complex control switching and is limited in application scenarios, so it cannot fully realize dual SIM dual standby in practice.

[0067] To address the aforementioned issues, this application aims to achieve dual-SIM dual-standby or multi-SIM multi-standby functionality in a single mobile terminal without employing multiple chips or multi-channel RF chips. When transmitting data, the data corresponding to different user identification cards is aggregated, and then transmitted through a single channel. The network-side device receives the aggregated data, which only needs to be split and transmitted through different channels for each user identification card. By aggregating and splitting the data, correct data transmission is achieved while reducing the need for physical channels.

[0068] Figure 2 This is a flowchart illustrating a data communication method provided in an embodiment of the present invention. The method can be applied to a baseband chip, which is located in a mobile terminal. The method includes steps S201 and S202.

[0069] Step S201: When it is determined that at least two user identification cards in the mobile terminal need to send data, the user plane data corresponding to the at least two user identification cards are aggregated to obtain a first information packet.

[0070] A mobile terminal can be equipped with at least two Subscriber Identity Modules (SIMs). When at least two SIMs need to transmit data, the data processing module in the baseband chip can receive the user plane data from both SIMs and perform aggregation processing. The user plane data represents the service data that the SIMs need to transmit. Through aggregation processing, the user plane data corresponding to the at least two SIMs can be aggregated into a first information packet.

[0071] Figure 3 This is a schematic diagram of a baseband chip processing data according to an embodiment of the present invention. For example, a mobile terminal has n user identification cards. When the n user identification cards need to send data, such as user identification card 1 needing to perform SMS sending service, user identification card 2 needing to perform data sending service in a certain application, etc., the data processing module in the baseband chip can aggregate the user plane data corresponding to the n user identification cards 1 respectively.

[0072] Step S202: Send the first information packet to the network-side device through a physical channel, so that the network-side device can split the first information packet and send the split user plane data to the corresponding target mobile terminals respectively.

[0073] Upon receiving the first data packet, it can be transmitted through a single physical channel between the RF chip and the network-side device. Since the baseband chip aggregates data from multiple user identification cards before transmitting data, data transmission via a single physical channel is sufficient.

[0074] When the network-side device receives the first information packet, it can split the first information packet to obtain the split user plane data, and then send the split user plane data to different target mobile terminals through different channels.

[0075] Figure 4 This is a schematic diagram of a data communication method provided in an embodiment of the present invention, as shown below. Figure 4 As shown, when data is transmitted between the baseband chip and the network-side device, the data is aggregated and can be transmitted using a single physical channel, compared to... Figure 1 There is no need to establish multiple physical channels between the mobile terminal and the network-side equipment based on hardware.

[0076] This invention provides a data communication method applied to a baseband chip, which is installed in a mobile terminal. The method includes: when it is determined that at least two user identification cards (SIM cards) in the mobile terminal need to send data, aggregating the user plane data corresponding to the at least two SIM cards to obtain a first information packet; sending the first information packet to a network-side device through a single physical channel, so that the network-side device splits the first information packet and sends the split user plane data to the corresponding target mobile terminals respectively. This enables the mobile terminal to transmit data based on a single physical channel by aggregating the data of each SIM card, thereby achieving multi-SIM card services based on a single channel of a single chip, eliminating the need for multiple radio frequency chips and reducing hardware and manufacturing costs.

[0077] Optionally, the first information packet includes at least a portion of the user identification card's identification information; the method further includes:

[0078] Obtain card information and send the card information to the network side device, so that the network side device can determine the user identification card corresponding to the split user face data based on the card information and send the split user face data to the target mobile terminal corresponding to the user identification card respectively.

[0079] The card information refers to the identification information of at least a portion of the user identification card inserted into the mobile terminal.

[0080] When the baseband chip transmits the aggregated data to the network-side device through a physical channel, the network-side device needs to split the data and determine which user identification card (SIM card) in the mobile terminal corresponds to each split data segment. To accurately determine the SIM card corresponding to each split data segment, identification information can be set for different SIM cards, thus allowing for the mapping between the SIM card and the segmented data based on the corresponding identification information.

[0081] When a mobile terminal is powered on, the baseband chip can obtain card information, specifically the identification information of the user identification card inserted into the mobile terminal. Identification information can be set for some or all user identification cards. For example, identification information can be set for all user identification cards, such as user identification card 1 corresponding to identifier 01, user identification card 2 corresponding to identifier 02, etc.; alternatively, the user can designate one of multiple user identification cards as the primary card and set identification information for the other user identification cards. For example, user identification card 1 is the primary card and no identification information is set, user identification card 2 corresponds to identifier 02, user identification card 3 corresponds to identifier 03, etc. After obtaining the card information, the baseband chip can send the card information to the network-side device.

[0082] When the baseband chip aggregates user plane data from various user identification cards to generate the first information packet, it can add corresponding identification information to each user plane data. When the network-side device receives the first information packet, it can split the first information packet to obtain multiple user plane data and corresponding identification information. Based on the identification information, it can determine the user identification card corresponding to the user plane data, and then send the user plane data to the target mobile terminal. The target mobile terminal can determine the target based on the service information corresponding to different user identification cards.

[0083] By setting identification information for at least a portion of the user identification card in the mobile terminal and sending it to the network-side device, the network-side device can determine the user identification card corresponding to the split user plane data based on the card information, thereby achieving accurate transmission of user plane data.

[0084] Optionally, the method further includes:

[0085] The first control plane data is sent to the network-side device through the physical channel, so that the network-side device can reconfigure the physical channel based on the first control plane data; the first control plane data represents the user identification card with newly enabled services and the corresponding service information in the mobile terminal.

[0086] Accordingly, the first information packet is sent to the network-side device through a physical channel, including:

[0087] The first information packet is sent to the network-side device through the reconfigured physical channel.

[0088] Mobile terminals rely on physical transmission channels to send or receive data. These physical channel resources are configured by the network-side equipment. The network-side equipment determines the bandwidth of the physical channel based on the number of user identification cards (SIM cards) in the mobile terminal and the services provided by those SIM cards. For example, the required physical channel bandwidth differs depending on whether one SIM card is performing a service or two SIM cards are performing services. Therefore, when a SIM card in the mobile terminal activates a service, it can send first control plane data to the network-side equipment, allowing the network-side equipment to reconfigure the physical channel based on this first control plane data.

[0089] Specifically, the first control plane data may include newly activated user identification cards and corresponding service information. The bandwidth required varies depending on the type of service; for example, voice calls and SMS require different bandwidths.

[0090] Once the network-side device reconfigures the physical channel, the mobile terminal can send data based on the reconfigured physical channel.

[0091] For example, when SIM 1 is engaged in a service, if SIM 2 initiates a service, the data processing module in the baseband chip can send first control plane data to the network side. This allows the network side device to obtain this information and calculate the physical resources required for SIM 2 to execute the service. The first control plane data indicates that SIM 2 has initiated a service of type A, thus reconfiguring the physical channel of SIM 1, increasing the bandwidth of the reconfigured physical channel. After reconfiguration, data from both SIM cards and tag information can be transmitted to the network side device through the reconfigured physical channel.

[0092] When a new user identification card is added to enable services, the network-side equipment can reconfigure the physical channel through the transmission of data from the first control plane to meet the data transmission needs of multiple user identification cards in the mobile terminal.

[0093] Optionally, the first control plane data is generated by the user identification card in the mobile terminal when it actively initiates the service or responds to the received service activation message.

[0094] There are two scenarios for newly activated services: one is when the user identification card in the mobile terminal actively initiates the service, such as when user identification card 2 actively makes a phone call; the other is when the user identification card in the mobile terminal receives the service, such as when another mobile terminal calls user identification card 2 in this mobile terminal. First control plane data can be generated for both scenarios.

[0095] In the first scenario, first control plane data can be directly generated and transmitted to the network-side device via the physical channel. In the second scenario, the network-side device first receives the service information from SIM 2, adds corresponding identification information to this information, and sends it to the data processing module in the baseband chip via the physical transmission channel. Upon receiving this information, the data processing module parses it and sends it to SIM 2. When SIM 2 responds to the service, it generates first control plane data and transmits it to the network-side device via the physical channel.

[0096] When a user identification card in a mobile terminal initiates a service or responds to a received service, it can generate first control plane data, thereby enabling the reconfiguration of the physical channel in both cases to meet the needs of multiple user identification cards performing corresponding tasks.

[0097] Optionally, the method further includes:

[0098] The second control plane data is sent to the network-side device through the physical channel, so that the network-side device can reconfigure the physical channel based on the second control plane data; the second control plane data represents the user identification card and corresponding service information of the newly added terminated service in the mobile terminal; the second control plane data is generated when the newly added terminated service user identification card in the mobile terminal actively terminates the service or responds to the received termination service.

[0099] When the baseband chip generates second control plane data, it can send this data to the network-side device via the physical channel. Second control plane data can also be generated when one or more SIM cards in the mobile terminal have terminated services. Upon receiving the second control plane data, the network-side device can reconfigure the physical channel based on changes in the mobile terminal's SIM card services. Specifically, for second control plane data, the bandwidth of the reconfigured physical channel is reduced.

[0100] The newly added termination of services includes two situations: one is that the user identification card in the mobile terminal actively terminates the service, such as user identification card 2 actively hanging up the phone; the other is that the user identification card in the mobile terminal passively terminates the service, such as another mobile terminal hanging up the call with user identification card 2 in this mobile terminal. Second control plane data can be generated for both situations.

[0101] In the first scenario, second control plane data can be directly generated and transmitted to the network-side device via the physical channel. In the second scenario, the network-side device first receives the service termination information sent to the user identification card, adds corresponding identification information to this information, and sends it to the data processing module in the baseband chip via the physical transmission channel. Upon receiving this information, the data processing module parses it and sends it to the user identification card 2. When the user identification card 2 responds to the service, it generates second control plane data and transmits it to the network-side device via the physical channel.

[0102] When at least one user identification card in a multi-SIM service terminates its service, second control plane data can be sent to the network-side device, enabling the network-side device to reconfigure the physical channel and allocate appropriate air interface resources to the mobile terminal, thereby reducing the allocation of unnecessary resources to the mobile terminal.

[0103] Figure 5 This is a flowchart illustrating another data communication method provided in an embodiment of the present invention; as shown below. Figure 5 As shown, the method further includes:

[0104] Step S501: Receive the second information packet sent by the network-side device through the physical channel.

[0105] The second information packet is obtained by aggregating the user plane data corresponding to the at least two user identification cards when the network-side device determines that there is data to be sent to at least two user identification cards in the same mobile terminal; the second information packet includes the identification information of at least some user identification cards.

[0106] When a mobile terminal receives data, if other mobile terminals have sent data to at least two user identification cards (SIM cards) within that mobile terminal, the network-side device can aggregate the received data to obtain a second data packet. During aggregation, the network-side device can add identification information. This identification information can be added based on pre-received SIM card information sent by the mobile terminals.

[0107] Once the data is aggregated, it can be transmitted through a physical channel with the mobile terminal.

[0108] Step S502: The second information packet is split, and the split user face data is sent to the corresponding user identification card according to the identification information.

[0109] When the baseband chip in the mobile terminal receives the second information packet, it can split the second information packet to obtain different user plane data and corresponding identification information, thereby determining the user identification card corresponding to each user plane data, and then sending the corresponding user plane data to the user identification card.

[0110] For multiple data reception processes, the network-side equipment aggregates multiple data, transmits the aggregated data based on a single physical channel, and the baseband chip splits the aggregated data, thereby realizing the data reception process based on a single physical channel.

[0111] Figure 6 This is a flowchart illustrating another data communication method provided in an embodiment of the present invention, as shown below. Figure 6 As shown, the method is applied to a network-side device, and the method includes steps S601 and S602:

[0112] Step S601: Receive the first information packet sent by the baseband chip through one physical channel.

[0113] The first information packet is obtained by the baseband chip aggregating the user plane data corresponding to the at least two user identification cards in the mobile terminal when it determines that at least two user identification cards in the mobile terminal need to send data; the baseband chip is installed in the mobile terminal.

[0114] Step S602: The first information packet is split and the split user plane data is sent to the corresponding target mobile terminals respectively.

[0115] This invention provides a data communication method applied to a network-side device. The method includes: receiving a first information packet sent by a baseband chip through a single physical channel. The first information packet is obtained by the baseband chip aggregating user plane data corresponding to at least two user identification cards (SIM cards) in a mobile terminal when it determines that at least two SIM cards need to send data. The baseband chip is configured to split the first information packet in the mobile terminal and send the split user plane data to the corresponding target mobile terminals. This enables the mobile terminal to aggregate data from each SIM card through the baseband chip when sending data, thereby achieving transmission based on a single physical channel. The network-side device correctly sends the data through data splitting, thus enabling multi-SIM card services to be completed on a single channel of a single chip, eliminating the need for multiple radio frequency chips and reducing hardware and manufacturing costs.

[0116] Optionally, the first information packet includes at least a portion of the user identification card's identification information; the method further includes:

[0117] Receive card information sent by the baseband chip;

[0118] Accordingly, the split user plane data is sent to the corresponding target mobile terminals, including:

[0119] Based on the card information, determine the user identification card corresponding to each of the split user face data, and send the split user face data to the target mobile terminal corresponding to each user identification card.

[0120] The card information refers to the identification information of at least a portion of the user identification card inserted into the mobile terminal, obtained by the baseband chip.

[0123] The physical channel is reconfigured based on the first control plane data; the first control plane data represents the newly added user identification card with enabled services and the corresponding service information in the mobile terminal;

[0124] Correspondingly, the first information packet sent by the baseband chip is received through a physical channel, including:

[0125] The first information packet is received by the baseband chip through the reconfigured physical channel.

[0126] Optionally, the first control plane data is generated by the user identification card in the mobile terminal when it actively initiates the service or responds to the received service activation message.

[0127] Optionally, the method further includes:

[0129] The physical channel is reconfigured based on the second control plane data; the second control plane data represents the user identification card and corresponding service information of the newly added terminated service in the mobile terminal; the second control plane data is generated when the newly added terminated service user identification card in the mobile terminal actively terminates the service or responds to the received termination service.

[0130] Optionally, the method further includes:

[0132] The second information packet is sent to the baseband chip through the physical channel, so that the baseband chip can split the second information packet and send the split user plane data to the corresponding user identification card according to the identification information.

[0133] The execution process of the network-side device corresponds to the execution process of the baseband chip side, and the implementation principle is the same. For the specific implementation process, please refer to the implementation of the baseband chip side, which will not be repeated here.
