Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method, device, storage medium, and program product. Background Art

[0002] With the development of communications, most current terminal devices support dual SIM dual active (DSDA) functionality. DSDA allows two subscriber identity modules (SIMs) to be installed in a single terminal device. This allows the devices to simultaneously send and receive services on both SIMs. For example, while a terminal device is using one SIM card for voice calls, it can also use the other SIM card for data services (such as surfing the Internet).

[0003] In related technologies, DSDA includes DSDA transmission sharing mode and DSDA transmission exclusive mode. In DSDA transmission sharing mode, the terminal device usually needs to use the same transmission channel through time division multiplexing (TDM) to send service data corresponding to two SIM cards.

[0004] In DSDA transmission sharing mode, when the uplink transmission services corresponding to the two SIM cards conflict in time, the terminal device will give priority to sending the service data corresponding to the SIM card running the higher-priority service. However, if the SIM card running the higher-priority service continues to have uplink scheduling, it will continue to occupy the transmission channel, resulting in the terminal device being unable to send service data to the SIM card running the lower-priority service for a long time. Summary of the Invention

[0005] Embodiments of the present application provide a communication method, device, storage medium, and program product that can reduce the probability that a terminal device cannot send service data of a SIM card running a low-priority service.

[0009] In this solution, the first network device corresponding to the first card sends the time domain resources used by the first card to transmit service data to the second network device corresponding to the second card performing a low-priority service. Based on the received time domain resource information, the second network device corresponding to the second card schedules the second card only on time domain resources not used by the first card to transmit service data. This method effectively increases the probability of successful uplink service data transmission for the second card, thereby improving the user experience.

In some network structures, network devices may include centralized unit (CU) nodes and distributed unit (DU) nodes.

[0093] Optionally, the network device and terminal device in the embodiments of the present application may also be referred to as a communication device or communication device, which may be a general device or a dedicated device, and the embodiments of the present application do not specifically limit this.

[0094] In order to better understand the technical solution provided by this application, the communication system architecture of this application is first described below.

[0095] Figure 1 A schematic diagram of the structure of a communication system provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the communication system includes a terminal device 1, a network device 2 and a network device 3.

[0096] Terminal device 1 performs uplink transmission and downlink transmission with network device 2 and network device 3. The link used for uplink transmission between terminal device 1 and network device 2 and network device 3 can be called uplink (UL), and the link used for downlink transmission between terminal device 1 and network device 2 and network device 3 can be called downlink (DL). It can be understood that the communication system can also include more terminal devices and network devices. Figure 1 This is only a schematic diagram and does not limit the applicable scenarios of the technical solution provided in this application.

[0097] SIM card 1 and SIM card 2 can be set in terminal device 1. SIM card 1 and SIM card 2 can be connected to the same operator network or different operator networks respectively, and this application does not limit this. SIM card 1 and SIM card 2 can be connected to the same access network device or different access network devices respectively, and this application does not limit this.

[0098] The following describes the solution by taking SIM card 1 and SIM card 2 as an example in which SIM card 1 and SIM card 2 are connected to different network devices.

[0099] When one of the two SIM cards (referred to as card) executes a high-priority service with high real-time requirements (for example, voice call service, etc.) through terminal device 1, the other SIM card can execute a low-priority service with low real-time requirements (for example, web browsing service, etc.) through terminal device 1.

[0100] For example, during time period 1, SIM card 1 executes a high-priority service with a high real-time requirement through terminal device 1, while SIM card 2 executes a low-priority service with a low real-time requirement through terminal device 1. During time period 2, SIM card 2 executes a high-priority service with a high real-time requirement through terminal device 1, while SIM card 1 executes a low-priority service with a low real-time requirement through terminal device 1. In other words, the SIM card that executes the high-priority service through terminal device 1 and the SIM card that executes the low-priority service through terminal device 1 can vary, and this application does not limit this.

[0101] In the following embodiments, description will be made by taking an example in which the terminal device 1 executes a high-priority service through the SIM card 1 and the terminal device executes a low-priority service through the SIM card 21 .

[0102] Terminal device 1 can use SIM card 1 to communicate with network device 2, and terminal device 1 can use SIM card 2 to communicate with network device 3. Terminal devices 1 using SIM card 1 and SIM card 2 can communicate using DSDA. In this communication mode, both SIM cards can perform communication services simultaneously.

[0103] When terminal device 1 is configured with only one RF transmission channel (i.e., terminal device 1 is in DSDA transmission sharing mode, referred to as transmission sharing mode), the two SIM cards can use time division multiplexing to transmit signals to the network device using the same RF transmission channel at different times. In this case, the mode in which the two SIM cards are located can be called time division duplexing (TDD) mode. The RF transmission channel can also be referred to as the RF transmission path, uplink channel, uplink path, etc.

[0104] In some embodiments, terminal device 1 can transmit uplink data based on the uplink scheduling of network device 2. For example, terminal device 1 sends uplink data to network device 2 via SIM card 1 on the uplink resources configured by network device 2 for SIM card 1. Uplink data can also be referred to as uplink traffic, uplink traffic data, etc.

[0105] In some embodiments, terminal device 1 may transmit uplink data based on uplink scheduling of network device 3. For example, terminal device 1 sends uplink data to network device 3 via SIM card 2 on the uplink resources configured by network device 3 for SIM card 2.

[0106] The following first introduces the time domain resources of the uplink resources used by the SIM card to send uplink service data.

[0107] In the embodiment of the present application, time domain resources may refer to: frames, time slots, and symbols used for uplink and downlink (UL & DL) transmissions, wherein the symbols may refer to orthogonal frequency division multiplexing (OFDM) symbols.

[0108] refer to Figure 2A , Figure 2A The schematic diagram of the structure of time domain resources is exemplarily shown.

[0109] like Figure 2A As shown, the duration of a frame is generally 10 milliseconds (ms); a frame may generally include 10 subframes, which may be marked as subframe 0 to subframe 9 respectively;

[0110] A subframe can include one or more time slots, and the number of time slots is related to the subcarrier spacing. For example, when the subcarrier spacing is 15 kilohertz (KHz), a subframe can include one time slot, which can be marked as Slot0; when the subcarrier spacing is 30 KHz, a subframe can include two time slots, marked as Slot0 and Slot1; when the subcarrier spacing is 60 KHz, a subframe can include four time slots, marked as Slot0, Slot1, Slot2, and Slot3. The following embodiments are described based on a subcarrier spacing of 30 KHz and a subframe consisting of two time slots.

[0111] A timeslot typically includes 14 symbols, which can be denoted as s0 to s13. A symbol is the smallest unit of the time domain resource structure. A symbol can be an uplink symbol used for uplink transmission, which is marked as "U," or a downlink symbol used for downlink transmission, which is marked as "D." Based on the ratio of uplink and downlink symbols in a timeslot, timeslots can be divided into three types: uplink timeslots, downlink timeslots, and flexible timeslots.

[0112] Among them, such as Figure 2B As shown in (a) in FIG, the uplink time slot can be marked as "U", and all 14 symbols in the uplink time slot are uplink symbols; Figure 2B As shown in (b) in FIG, the downlink time slot can be marked as "D", and all 14 symbols in the downlink time slot are downlink symbols; Figure 2B The flexible time slots shown in (c) of Figure 1 are marked "S" and are divided into fully flexible time slots and hybrid time slots. The 14 symbols in a fully flexible time slot can be used for uplink or downlink transmission, or as guard intervals or reserved resources based on specific traffic scenarios. A hybrid time slot includes at least one uplink symbol and / or downlink symbol. Figure 2B In the mixed time slot shown, s0 to s7 are downlink symbols, s8 and s9 are guard intervals, and s10 to s13 are uplink symbols.

[0113] like Figure 2C As shown, within a period of a specified duration (e.g., 2.5ms, 5ms, etc.), different time slot ratios can be used in the time domain based on the ratio between uplink time slots, downlink time slots, and flexible time slots. The following examples introduce several time slot ratio structures:

[0114] like Figure 2C As shown in (a), with a period of 2.5 ms, the time slot ratio can be downlink time slot: flexible time slot: uplink time slot = 3:1:1;

[0115] like Figure 2CAs shown in (b), with a period of 5 ms, the time slot ratio can be downlink time slot: flexible time slot: uplink time slot = 5:2:3;

[0116] like Figure 2C As shown in (c), with a period of 5 ms, the time slot ratio can be downlink time slot: flexible time slot: uplink time slot = 8:1:1;

[0117] like Figure 2C As shown in (d), with a period of 5 ms, the time slot ratio can be downlink time slot: flexible time slot: uplink time slot = 7:1:2;

[0118] It should be noted that the time domain resource structure introduced above is only used to exemplify the present application and does not constitute a specific limitation to the present application.

[0119] Generally speaking, the time domain resource structure of a network device is fixed. The network device can broadcast its own time domain resource structure. When a terminal device accesses a cell under the network device, it can obtain the time domain resource structure of the network device and determine the time domain resources for uplink and downlink transmission based on the time domain resource structure. For example, when terminal device 1 uses SIM card 1 to access the cell corresponding to network device 2, it can obtain the time domain resource structure of network device 2. Terminal device 1 can determine the time domain resources for uplink and downlink transmission between SIM card 1 and network device 2 based on the time domain resource structure of network device 2. When terminal device 1 uses SIM card 2 to access the cell corresponding to network device 3, it can obtain the time domain resource structure of network device 3. Terminal device 1 can determine the time domain resources for uplink and downlink transmission between SIM card 2 and network device 3 based on the time domain resource structure of network device 3.

[0120] Optionally, the network device may also allocate time domain resources to the terminal device through signaling when the terminal device accesses a cell under the network device. For example, when terminal device 1 uses SIM card 1 to access the cell corresponding to network device 2, network device 2 may send time domain resources to terminal device 1 through cell-specific radio resource control signaling, UE-specific radio resource control signaling, etc.

[0121] Reference Figure 3 , Figure 3 A schematic diagram of time domain resources configured by the network device 2 for the SIM card 1 and a schematic diagram of time domain resources configured by the network device 3 for the SIM card 2 are exemplarily shown.

[0122] like Figure 3As shown, in the same time period (10ms), the time slot ratio of the time domain resources configured by network device 2 for SIM card 1 is D:S:U=8:1:1, and the time slot ratio of the time domain resources configured by network device 3 for SIM card 2 is D:S:U=7:1:2.

[0123] In some embodiments, when the terminal device is in the transmission sharing mode, when the network device 2 schedules the SIM card 1 to Figure 3 When a certain time slot (e.g., time slot 9) within the 10ms shown transmits uplink service data for a high-priority service, the RF transmission path of terminal device 1 is preempted by SIM card 1 for the entire 10ms. Because the RF transmission path is preempted by SIM card 1, SIM card 2 is unable to transmit uplink data in the uplink time slot (e.g., time slot 9 or time slot 19) configured for it by network device 3. In other words, when the time slots used by SIM cards 1 and 2 for the RF transmission path conflict, the terminal device prioritizes transmitting the uplink service data of SIM card 1, which is performing the high-priority service, and discards the uplink service data of SIM card 2, which is performing the low-priority service, resulting in a poor user experience.

[0124] In view of this, an embodiment of the present application provides a communication method and related apparatus. When a first card (e.g., SIM card 1) performing a high-priority service uses an uplink channel to send service data in a certain time slot, the first network device corresponding to the first card sends the time domain resources used by the first card to send service data to the second network device corresponding to the second card (e.g., SIM card 2) performing a low-priority service. The second network device corresponding to the second card, based on the received time domain resource information, only schedules the second card on the time domain resources not used by the first card to send service data. Through the above method, the probability of the second card's uplink service data being discarded can be effectively reduced, thereby improving the user experience.

[0125] In the embodiment of the present application, the RF transmission path of the terminal device may be occupied by not only the first card or the second card, but also other modules or components of the terminal device, such as a satellite communication module, etc., which is not limited in the present application.

[0126] The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other. For the same or similar content, such as the explanation of terms or nouns, and the explanation of steps, etc., different embodiments can refer to each other and will not be repeated.

[0127] Figure 4 A flow chart of a communication method provided in an embodiment of the present application is shown as follows: Figure 4 As shown, the communication method provided in the embodiment of the present application includes:

[0128] S401: A terminal device sends first indication information to a first network device. The first indication information is used to indicate that the terminal device includes a first card and a second card.

[0129] In the embodiment of the present application, the terminal device includes a first card and a second card, and the first card and the second card can compete for the same radio frequency transmission path of the terminal device through TDM to transmit uplink data. The first network device is the network device to which the cell where the terminal device resides through the first card belongs.

[0130] For example, the terminal device is Figure 1 The terminal device 1, the first card of the terminal device is the SIM card 1 of the terminal device 1, the second card of the terminal device is the SIM card 2 of the terminal device 1, and the first network device is Figure 1 Network device 2 in.

[0131] In some embodiments, the first indication information may include an identifier of the terminal device, an identifier of the first card, and an identifier of the second card.

[0132] Exemplarily, the identifier of the terminal device may be the international mobile equipment identity (IMEI) of the terminal device, the identifier of the first card may be the international mobile subscriber identity (IMSI) of the first card, and the identifier of the second card may be the international mobile subscriber identity (IMSI) of the second card.

[0133] Optionally, the identifier of the terminal device may also be an electronic serial number (ESN), a mobile equipment identity document (MEID), or the identifier of the first card or the second card may also be an integrated circuit card identification code (ICCID) of the first card or the second card. The embodiment of the present application does not limit the identifier of the terminal device, the first identifier, and the identifier of the second card.

[0134] Optionally, the first card is a contracted card of the first network device. When the terminal device sends the first indication information to the first network device through the first card, the first network device can identify the identifier of the first card. The first indication information can also include the identifier of the terminal device and the identifier of the second card.

[0135] In some embodiments, the first indication information may be carried in uplink control information (UCI) or in a radio resource control (RRC) message.

[0136] In a possible implementation, the terminal device may send the first indication information to the first network device through a non-access stratum (NAS).

[0137] In some embodiments, when a terminal device operates in a transmission sharing mode and is scheduled to execute a target service via a first card, the terminal device transmits first indication information to a first network device via the first card. The target service is a service with a priority higher than a preset priority, i.e., the target service is a high-priority service. For example, the target service may be a voice call service, a video call service, or the like.

[0138] Optionally, the terminal device being scheduled to execute the target service through the first card may include the terminal device being executing the target service through the first card, or the terminal device determining that the first card has been assigned the target service.

[0139] S402: The first network device sends second indication information to the second network device. The second indication information is used to indicate the first time domain resource.

[0140] In the embodiment of the present application, the second network device is a network device to which the cell where the terminal device resides through the second card belongs. Figure 1 The terminal device 1 in the second network device is Figure 1 The first time domain resource is a time domain resource used by the terminal device when executing the target service through the first card.

[0141] When the first network device receives the first indication information sent by the terminal device, if the first network device can determine that the terminal device is a dual-card terminal including a first card and a second card based on the first indication information, the first network device can send a second indication information to the second network device to indicate the first time domain resource to be used by the terminal device when executing the target service through the first card.

[0142] In some embodiments, when the first network device sends the second indication information to the second network device, it is necessary to determine the second network device.

[0143] In a possible implementation, the first network device may determine the second network device according to the identifier of the second card. For example, the first network device may determine the second network device from the core network device based on the identifier of the second card and the location information of the terminal device.

[0144] In a possible implementation, the first indication information may also carry an identifier of the second network device, and the first network device determines the second network device according to the identifier of the second network device.

[0145] In some embodiments, the second indication information includes: scheduling information of the first time domain resources.

[0146] In some embodiments, the scheduling information of the first time domain resource may be periodic scheduling information, for example, the scheduling information may include information about the scheduling period and the position of the scheduled time unit in the scheduling period; the scheduling period information includes: the duration of the scheduling period and / or the start time of the scheduling period. Figure 3 As shown, the scheduling information of the first card is to schedule slot9 and slot19 every 10ms as a cycle starting from cycle n, or, the scheduling information of the first card is to schedule slot9 and slot19 every 10ms as a cycle for m cycles, or, the scheduling information of the first card is to schedule slot9 and slot19 every 10ms as a cycle starting from cycle n, and schedule slot9 and slot19 every 10ms as a cycle for m cycles.

[0147] In some embodiments, the scheduling information of the first time domain resource may be non-periodic scheduling information, for example, the scheduling information may include: scheduling duration, location of the scheduled time unit. Figure 3 As shown, the scheduling information of the first card is that within a time period of T, slots 9 and 19 in the mth frame and the nth frame are all scheduled.

[0148] In some embodiments, the second indication information may be carried in an RRC message.

[0149] In some embodiments, in order for the second network device to determine the second card to be scheduled, the second indication information may further include: an identifier of the second card.

[0150] In some embodiments, the first network device may send the second indication information via a communication interface between the first network device and the second network device, such as an X2 interface or an Xn interface.

[0151] In some embodiments, the first network device may also send the second indication information to the second network device via its own core network device. For example, the first network device sends the second indication information to its own core network device, the core network device to which the first network device belongs forwards the second indication information to the core network device to which the second network device belongs, and the core network device to which the second network device belongs sends the second indication information to the second network device. Alternatively, the first core network device forwards the second indication information to the core network device to which the first network device belongs, and the core network device to which the first network device belongs sends the second indication information to the second network device.

[0152] In some embodiments, network devices belonging to the same communication network system, or network devices belonging to a co-built and shared communication network system have communication capabilities, and co-built and shared communication network systems have communication capabilities. Figure 1 The network device 2 and the network device 3 in the communication belong to the communication network system A, and the network device 2 and the network device 3 have the communication capability. Alternatively, the network device 2 belongs to the communication network system A, and the network device 3 belongs to the communication network system B, and the communication network system A and the communication network system B are co-built and shared communication network systems, and the communication network system A and the communication network system B have the communication capability with the network device 2 and the network device 3. Therefore, when the first network device receives the first indication information, it can determine based on the first indication information that the second network device and itself are network devices belonging to the same communication network system, or that the second network device belongs to a network device in a co-built and shared communication network system, and then send the second indication information to the second network device. If it is determined that the second network device and itself are network devices that do not belong to the same communication network system, and the communication network systems to which they belong are not co-built and shared communication network systems, the first network device will not perform the action of sending the second indication information.

[0153] Exemplarily, when the identifier of the first card and the identifier of the second card belong to the same communication network system, the second indication information is sent to the second network device; or, when the identifier of the first card belongs to the first communication network system and the identifier of the second card belongs to the second communication network system, the frequency resources are shared between the first communication network system and the second communication network system, and the second indication information is sent to the second network device.

[0154] In some embodiments, there may be a system frame offset between the time domain resources of the first network device and the time domain resources of the second network device, that is, the system frames between the time domain resources of the first network device and the time domain resources of the second network device may be misaligned. Before the first network device sends the second indication information to the second network device, the first network device needs to determine whether the system frames between the first network device and the second network device are aligned.

[0155] In a possible implementation, the first network device obtains a system frame offset value (also called a system frame time domain offset value) between the time domain resources of the first network device and the time domain resources of the second network device through the core network device to which it belongs.

[0156] In one possible implementation, the system frame offset value between the time domain resources of the first network device and the time domain resources of the second network device can be sent by the terminal device to the first network device, for example, carried in the first indication information, or in new indication information.

[0157] When the first network device determines that the offset value of the system frame between the time domain resources of the first network device and the time domain resources of the second network device is not a preset value (for example, the preset value is 0), the first network device sends the offset of the system frame between the time domain resources of the first network device and the time domain resources of the second network device to the second network device. For example, it is carried in the second indication information. If the first network device determines that the offset value of the system frame between the time domain resources of the first network device and the time domain resources of the second network device is a preset value, the offset value is not sent to the second network device. It should be understood that the preset value can be a value agreed upon in the protocol, or it can be a value sent to the first network device by the terminal device.

[0158] S403: The second network device schedules the terminal device that executes the service through the second card on the second time domain resource.

[0159] In the embodiment of the present application, the second time domain resource is a time domain resource other than the first time domain resource.

[0160] When the second network device receives the second indication information, it can determine the scheduling information of the time domain resources used by the terminal device when executing the target service through the first card, as well as the second card in the same terminal device as the first card based on the second indication information.

[0161] When the second network device determines the scheduling information of the time domain resources used by the terminal device to execute the target service through the first card, it can perform uplink scheduling on the time domain resources not occupied by the first card to execute the target service. Figure 3 As shown, the first card occupies slot 9 and slot 19 when executing the target service. When the second network device performs uplink scheduling on the terminal device through the second card, slot 9 and slot 19 can be avoided, and the terminal device can be uplink scheduled on slot 8 and slot 18 through the second card.

[0162] In some embodiments, the second network device schedules the terminal device that performs services through the second card on the second time domain resources, which may also be considered as low-priority scheduling of the terminal device that performs services through the second card.

[0163] In some embodiments, the information for instructing the second network device to schedule the terminal device that performs services through the second card on the second time domain resource when receiving the second indication information may be information agreed in the protocol or carried in the second indication information.

[0164] In the embodiment of the present application, the terminal device executing the service through the first card can also be called the first card executing the service, and the terminal device executing the service through the second card can also be called the first card executing the service.

[0165] In the communication method provided by an embodiment of the present application, a terminal device sends a first indication message to a first network device when being scheduled to execute a target service. The first indication message indicates that the terminal device is a dual-card terminal. Upon receiving the first indication message, the first network device sends a second indication message to a second network device. The second indication message indicates the time domain resources used by the terminal device to execute the target service through the first card. The second network device can avoid the time domain resources occupied by the first card when performing uplink scheduling on the second card of the terminal device. In this way, the probability of conflict between the time slots of the RF transmission path used by the first and second cards when the terminal device operates in a transmission sharing mode can be effectively reduced, thereby reducing the probability of service data executed by the second card being discarded, thereby improving the user experience.

[0166] Reference Figure 5 , Figure 5 The flowchart of another communication method provided by the embodiment of the present application is exemplarily shown. Figure 4 Based on the embodiment shown, Figure 5 As shown, the process of the communication method of this embodiment includes:

[0167] S501. A first network device sends third indication information to a second network device; the third indication information is used to indicate the end of execution of a target service.

[0168] In an embodiment of the present application, the target service is a high-priority service executed by the terminal device through the first card, and the third indication information includes a first identifier, which is used to indicate the end of execution of the target service. For example, the first identifier is 0 or 1, or end.

[0169] The terminal device executes the target service through the first card based on the scheduling of the first network device. The first network device can determine in real time whether the terminal device executes the target service through the first card. When the terminal device executes the target service through the first card, the first network device sends third indication information to the second network device.

[0170] In some embodiments, the third indication information includes an identifier of the second card.

[0171] The implementation manner in which the first network device sends the third indication information to the second network device can refer to the implementation manner in which the first network device sends the second indication information to the second network device, which is not elaborated in this embodiment of the present application.

[0172] S502: The second network device restores the time domain resources that the second network device schedules for the terminal device that executes the service through the second card from the second time domain resources to the default time domain resources.

[0173] In this embodiment of the present application, when the second network device receives the third indication information from the first network device, if it is determined based on the third indication information that the terminal device has finished executing the target service through the first card, the second network device may restore the scheduling of the terminal device executing the service through the second card on the second time domain resource to the scheduling of the terminal device executing the service through the second card on the default time domain resource. That is, uplink scheduling is performed on all time domain resources for the terminal device executing the service through the second card.

[0174] In some embodiments, the second network device resumes scheduling the terminal device that performs services through the second card on the default time domain resources, which can also be considered as releasing the low-priority scheduling of the terminal device that performs services through the second card. Through the above method, the efficiency of scheduling the terminal device that performs services through the second card can be improved.
