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 (such as mobile phones) support dual SIM dual active (DSDA). Under DSDA, terminal devices support dual SIM card services concurrently, meaning that the terminal device can send or receive services simultaneously through both SIM cards. For example, the terminal device can use one SIM card to perform a call service while using the other SIM card to perform a data service (such as surfing the Internet).

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

[0004] In DSDA transmission sharing mode, when a terminal device card has uplink data to transmit, it sends a scheduling request (SR) to the network device to which the card belongs via the uplink control channel to request uplink transmission resources. The time at which a low-priority service card sends an SR through the terminal device may conflict with the time at which a high-priority service card sends uplink data through the terminal device, resulting in a failure to send the SR through the terminal device. If the number of failed SR transmissions reaches the maximum number of SR transmissions, the terminal device of the low-priority service card will enter the random access channel (RACH) to request uplink resources, potentially causing communication interruption for the terminal device of the low-priority service card. Summary of the Invention

[0080] 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.

[0081] In order to better understand the technical solution provided by this application, the communication system architecture of this application is first described below.

[0082] 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.

[0083] Terminal device 1 can perform uplink 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.

[0084] like Figure 1 As shown, terminal device 1 can be provided with two subscriber identity modules (SIMs), namely SIM card 1 and SIM card 2. SIM card 1 and SIM card 2 can be connected to the same operator network or different operator networks, which is not limited in this application. SIM card 1 and SIM card 2 can be connected to the same network device or different network devices, which is not limited in this application.

[0085] The following example illustrates the solution by taking SIM card 1 and SIM card 2 as examples of connecting to different network devices. For example, Figure 1 The terminal device 1 shown communicates with the network device 2 via the SIM card 1 , and the terminal device 1 communicates with the network device 3 via the SIM card 2 .

[0086] 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.

[0087] 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.

[0088] The following combination Figure 2 The uplink scheduling process provided in the embodiment of the present application is described in detail.

[0089] refer to Figure 2 , Figure 2 The following is a schematic diagram of an uplink scheduling process provided by an embodiment of the present application. Figure 2 As shown, the uplink scheduling process involves the interaction between terminal device 1 and network device 2, and may include:

[0090] S201. Terminal device 1 sends an uplink scheduling request to network device 2. The uplink scheduling request is used to request resources for uplink data transmission.

[0091] After a radio resource control (RRC) connection is established between the terminal device 1 and the network device 2, when the terminal device 1 has uplink data to send, the terminal device 1 can send an SR to the network device 2.

[0092] In some embodiments, the terminal device 1 may send an SR to the network device 2 via the SIM card 1 .

[0093] In some embodiments, the terminal device 1 may send an SR to the network device 2 via a physical uplink control channel (PUCCH).

[0094] S202 . The network device 2 sends uplink grant (UL grant) information to the terminal device 1 . The UL grant information is used to indicate the uplink resources configured by the network device 2 for the terminal device 1 .

[0095] After receiving the SR, network device 2 can configure uplink resources for terminal device 1 and send UL grant information to terminal device 1. The UL grant information includes the uplink resources configured by network device 2 for terminal device 1. Uplink resources include uplink time-frequency domain resources. In the embodiment of the present application, uplink resources mainly refer to uplink time domain resources.

[0096] In some embodiments, the SR includes information about SIM card 1 of terminal device 1, for example, the information about SIM card 1 includes an international mobile subscriber identity (IMSI). After receiving the SR, network device 2 may configure uplink resources for SIM card 1 of terminal device 1 and send UL grant information to terminal device 1. The UL grant information includes the uplink resources configured by network device 2 for SIM card 1 of terminal device 1, which is recorded as uplink resource 1.

[0097] S203. Terminal device 1 sends uplink data and / or buffer status report (BSR).

[0098] After receiving the UL grant information, terminal device 1, in one example, sends uplink data or a BSR on uplink resource 1 through SIM card 1, where the BSR is used to indicate the amount of uplink data to be sent in the medium access control (MAC) layer buffer of terminal device 1. In another example, terminal device 1 sends uplink data and a BSR on uplink resource 1 through SIM card 1.

[0099] S204. Network device 2 sends an ACK / NACK message to terminal device 1.

[0100] In some embodiments, after the network device 2 successfully receives the uplink data sent by the terminal device 1 , the network device 2 may send an acknowledgement (ACK) message to the terminal device 1 .

[0101] In some embodiments, if network device 2 does not receive uplink data sent by terminal device 1 within a preset time period, or if network device 2 fails to receive uplink data sent by UE (data loss or decoding failure, etc.), network device 2 may send a negative acknowledgement (NACK) message to terminal device 1.

[0102] In some embodiments, after S203, the following steps may be further performed:

[0103] S205 . The network device 2 sends UL grant information to the terminal device 1 again. The UL grant information is used to indicate the uplink resources configured by the network device 2 for the terminal device 1 .

[0104] After receiving the BSR, network device 2 learns that the amount of uplink data sent by terminal device 1 is greater than the preset data amount. Network device 2 may reconfigure an uplink resource for terminal device 1, record it as uplink resource 3, and resend UL grant information to terminal device 1. The UL grant information includes indication information of uplink resource 3. Exemplarily, the indication information of uplink resource 3 is used to indicate the start time and duration of uplink resource 3, or to indicate the start time and end time of uplink resource 3. Terminal device 1 may send uplink data on uplink resource 3.

[0105] It should be understood that the uplink scheduling process between the terminal device 1 and the network device 3 is similar to the uplink scheduling process between the terminal device 1 and the network device 2, which can be referred to Figure 2 The embodiment shown.

[0106] Based on the above uplink scheduling process, network device 2 can configure uplink resource 1 for SIM card 1 of terminal device 1. Similarly, network device 3 can configure uplink resource 2 for SIM card 2 of terminal device 1.

[0107] In some embodiments, terminal device 1 includes a first timer and a first counter. When terminal device 1 sends an SR to network device 2, the first timer starts. During this period, the terminal device cannot send an SR to network device 2 again until the first timer reaches a first threshold. When the first timer reaches the first threshold, it is turned off. Terminal device 1 can send an SR to network device 2 when the next uplink timeslot arrives. The first threshold is used to indicate the minimum time interval between two consecutive SRs sent by the terminal device.

[0108] The first counter is used to indicate the number of times the terminal device 1 sends an SR. Each time the terminal device 1 sends an SR to the network device 2, the value of the first counter increases by 1. Optionally, the initial value of the first counter can be 0. Whenever the terminal device 1 sends an SR, when the terminal device 1 receives the ULgrant sent by the network device 2 within the preset time, it is determined that the SR sending is successful. When the terminal device 1 does not receive the ULgrant sent by the network device 2 within the preset time, the SR sending fails. The reason for the failure may be insufficient radio frequency channel resources of the terminal device 1, or large transmission path loss, which makes it impossible to complete the data sending.

[0109] If the SR fails to be sent, terminal device 1 will send the SR again to network device 2, and the value of the first counter will be incremented by one until the specified data is successfully sent, or when the value of the first counter is equal to the second threshold, terminal device 1 triggers the random access procedure (RACH). The second threshold is used to indicate the maximum number of times the SIM1 card in terminal device 1 can send an SR to the network device. The second threshold can be configured by network device 2 or set by terminal device 1, and this application does not impose any restrictions on this.

[0110] It can be understood that the first timer and the first counter are associated with the SIM card. When the terminal device 1 is a dual-card terminal including SIM card 1 and SIM card 2, the terminal device 1 also includes a second timer and a second counter. The first timer and the first counter serve SIM card 1, and record the time and number of times SR is sent for SIM card 1; the second timer and the second counter serve SIM card 2, and record the time and number of times SR is sent for SIM card 2. Alternatively, the first timer and the first counter serve SIM card 2, and record the time and number of times SR is sent for SIM card 2; the second timer and the second counter serve SIM card 1, and record the time and number of times SR is sent for SIM card 1. The embodiments of the present application are not limited to this.

[0111] In order to better understand the solution, the time domain resource structure of the uplink resources provided in the embodiment of the present application is introduced below.

[0112] 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.

[0113] refer to Figure 3A , Figure 3A The schematic diagram of the structure of time domain resources is exemplarily shown.

[0114] like Figure 3A 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;

[0115] 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.

[0116] 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.

[0117] Among them, such as Figure 3B 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 3B 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 3B 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 3B 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.

[0118] like Figure 3C 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:

[0119] like Figure 3C 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;

[0120] like Figure 3C As 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;

[0121] like Figure 3C 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;

[0122] like Figure 3C 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;

[0123] 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.

[0124] 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.

[0125] Continue to refer to Figure 1 , Figure 1 The terminal device 1 shown can communicate using a dual SIM and dual access (DSDA) method. In this communication method, two SIM cards can perform communication services simultaneously. That is, when one of the two SIM cards performs a high-priority service with a high real-time requirement (for example, a voice call service), the other SIM card can perform a low-priority service with a low real-time requirement (for example, a web browsing service).

[0126] 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.

[0127] In the following embodiments, description will be made by taking an example in which SIM card 1 executes a high-priority service through terminal device 1 and SIM card 2 executes a low-priority service through terminal device 1 .

[0128] When terminal device 1 is configured with only one RF transmission channel (i.e., terminal device 1 is in DSDA 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 called RF transmission path, uplink channel, uplink path, etc.

[0129] Reference Figure 4 , Figure 4 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.

[0130] like Figure 4As shown, in the same 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. Figure 4 It can be seen that the uplink time slots of the time domain resources of SIM card 1 and SIM card 2 overlap (for example, time slot 9 or time slot 19).

[0131] In some embodiments, in the DSDA transmission sharing mode, when the network device 2 schedules the SIM card 1 to Figure 4 When a certain time slot (e.g., time slot 9) within the 10ms shown transmits uplink 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 cannot transmit uplink data in the uplink time slot (e.g., time slot 9 or time slot 19) configured for it by network device 3.

[0132] like Figure 4 As shown, when the network device 2 schedules the SIM card 1 to send uplink data of a high-priority service in time slot 9 or time slot 19, within this time period, if the SIM card 2 of the terminal device 1 needs to send uplink data of a low-priority service, it can send an SR to the network device 3. Since the RF transmission path is preempted by the SIM card 1, the SR sent by the terminal device 1 to the network device 3 will fail. If the number of consecutive failures of the SR sent by the terminal device 1 to the network device 3 reaches a preset threshold, the terminal device 1 will trigger the RACH process to apply for uplink resources.

[0133] At this time, the connection between terminal device 1 and network device 3 is stable and the signal quality is good, which can meet the data transmission and reception between terminal device 1 and network device 3. However, since SIM card 2 of terminal device 1 is a low-priority service card, the time of sending SR conflicts with the time of sending uplink service data of SIM card 1 (high-priority service card), and the RF transmission path cannot be seized, resulting in SR sending failure. At this time, the RACH process is triggered, which not only takes a long time, but also may cause the risk of network connection disconnection during the process of reselecting the network, resulting in a poor user experience.

[0134] In view of this, an embodiment of the present application provides a communication method and related equipment. When the network device identifies that a SIM card of a terminal device of a dual-card terminal is currently a low-priority service card (also known as a low-priority service priority), the network device sends a first indication message to the terminal device to instruct the low-priority service card to update its SR sending parameters (number of times of sending and / or time interval for sending SR), and the updated SR sending parameter value is greater than the value before the update. By updating the SR sending parameter to increase the number of times the low-priority service card sends SR, or increasing the SR sending time of the low-priority service card, the probability of the low-priority service card sending SR successfully is increased, thereby reducing the probability of the terminal device triggering the RACH process, thereby improving the user experience.

[0135] 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.

[0136] 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.

[0137] Reference Figure 5 , Figure 5 The flowchart of a communication method provided by an embodiment of the present application is exemplarily shown. Figure 5 As shown, the communication method of this embodiment includes:

[0138] S501: When determining that the service priority of the second identity recognition module card of the terminal device is lower than the service priority of the first identity recognition module card, the network device sends first indication information to the terminal device.

[0139] In the embodiment of the present application, the first identity recognition module card may be SIM card 1, the second identity recognition module card may be SIM card 2, and the terminal device may be a dual-card terminal device including SIM card 1 and SIM card 2 (for example, Figure 1 The terminal device 1 in the network device may be a network device corresponding to the cell where the terminal device resides via the SIM card 2 (for example, Figure 1 Network devices in 3).

[0140] The first indication information is used to instruct the terminal device to update the value of the sending parameter of the scheduling request of the SIM card 2. The updated value of the sending parameter is greater than the value before the update, that is, the updated value tolerance of the sending parameter is higher.

[0141] In some embodiments, the sending parameters of the scheduling request include a maximum number of times the scheduling request is sent (sr-TransMax) and / or a minimum time interval for sending the scheduling request (sr-ProhibitTimer).

[0142] In some embodiments, when the terminal device accesses the cell of the network device through the SIM card, the network device may configure the value (default value) of the sending parameter of the scheduling request to the terminal device.

[0143] For example, when terminal device 1 accesses network device 2 through SIM card 1, the values ​​of the sending parameters of the configured scheduling request can be as follows:

[0144] sr-TransMax: Maximum number of SR transmissions, the default value is 8;

[0145] sr-ProhibitTimer: Minimum interval for sending SRs. The default value is 4 milliseconds.

[0146] When the terminal device 1 accesses the network device 3 through the SIM card 2, the configured sending parameters of the scheduling request may be as follows:

[0147] sr-TransMax: Maximum number of SR transmissions, the default value is 8;

[0148] sr-ProhibitTimer: Minimum interval for sending SRs. The default value is 4 milliseconds.

[0149] Optionally, the sending parameters of the above-mentioned scheduling request can also be customized by the terminal device or agreed in the protocol. It should be understood that the values ​​of the above-mentioned sending parameters can be set according to actual needs, and the embodiments of the present application are not limited to this. In the embodiments of the present application, the values ​​of the sending parameters and the sending parameters can represent the same meaning.

[0150] In some embodiments, the network device may determine that the service priority of the second identity recognition module card of the terminal device is lower than the service priority of the first identity recognition module card based on the following method.

[0151] A first possible implementation manner: the network device determines based on indication information of the terminal device.

[0152] Correspondingly, in this implementation, the following steps may be further included before S501:

[0153] S500: The network device receives second indication information from the terminal device. The second indication information is used to indicate that the service priority of SIM card 2 is lower than the service priority of SIM card 1.

[0154] The second indication information may include a first identifier, and the first identifier is used to indicate that the service priority of SIM card 2 is lower than that of SIM card 1. For example, the first identifier may be 0, 1, or low.

[0155] In some embodiments, when the terminal device identifies that a high-priority service (e.g., a call service) is scheduled to be executed through SIM card 1, it can determine that the service priority of SIM card 2 is lower than that of SIM card 1. In this case, SIM card 1 can be referred to as the high-priority service card, and SIM card 2 can be referred to as the low-priority service card. When the terminal device determines that SIM card 2 is the low-priority service card, it can send a second indication message to the network device.

[0156] It should be understood that when SIM card 1 and SIM card 2 are not executing high-priority services, they can be called ordinary service cards or non-priority service cards.

[0157] In some embodiments, the second indication information may be carried in an RRC message or uplink control information (UCI).

[0158] It should be understood that the terminal device can pre-set the priority of each service, for example, setting services with higher real-time requirements (such as voice calls) as high-priority services, and setting services with lower real-time requirements (such as video browsing, web browsing, etc.) as low-priority services. Alternatively, no pre-setting is performed, but the real-time requirements of each service are determined in real time, and this application does not impose any restrictions on this.

[0159] A second possible implementation manner: the network device determines based on the signal quality between the network device and the terminal device.

[0160] Exemplarily, when the terminal device has a first identity identification module card and a second identity identification module card, within a preset time, if the bit error rate of the service data sent by the terminal device through the second identity identification module card is greater than the preset bit error rate, and the signal quality of the uplink signal of the service data is greater than the preset threshold, it is determined that the service priority of the second identity identification module card is lower than the low service priority of the first identity identification module card.

[0161] The signal quality of the uplink signal may be the Reference Signal Receiving Power (RSRP), Signal Reception Strength (SRS), Channel Quality Indication (CQI), etc. The bit error rate is an indicator that measures the accuracy of data transmission within a specified time. The bit error rate = bit errors in transmission / total number of transmitted codes * 100%.

[0162] When the network device determines that the signal quality of the uplink signal between the terminal device and the network device is greater than a preset threshold (for example, RSRP>-100 decibel milliwatts (the dbm scale, dBm)), it can be determined that the connection between the current terminal device and the network device is stable and the signal quality is good. If the bit error rate of the service data sent by the terminal device in the last T time (for example, within 5 seconds) is greater than a preset bit error rate (for example, 20%), the network device can determine that SIM2 is a low-priority service card and there is a dual-card service conflict. The preset time can be customized by the network device or agreed upon by the protocol.

[0163] In some embodiments, in a second possible implementation manner, the network device may determine, based on the indication information sent by the terminal device, that the terminal device has the first identity recognition module card and the second identity recognition module card.

[0164] For example, the network device receives third indication information from the terminal device, where the third indication information is used to indicate that the terminal device has the first identity identification module card and the second identity identification module card.

[0165] The third indication information may include a second identifier, and the second identifier is used to indicate that the terminal device has the first identity recognition module card and the second identity recognition module card. For example, the second identifier may be 0 or 1, or dual, etc.

[0166] In some embodiments, the third indication information may be carried in an RRC message or in uplink control information (UCI).

[0167] When the network device determines based on any of the above methods that the service priority of the second identity recognition module card of the terminal device is lower than the service priority of the first identity recognition module card, the network device sends the first indication information to the terminal device.

[0168] In some embodiments, the first indication information includes a value of a sending parameter, or the first indication information includes an identifier of a value of a sending parameter.

[0169] Exemplarily, the network device may be provided with two sets of parameters for sending scheduling requests, for example, the first set is used to configure the terminal device when the terminal device first accesses (ie, for a service card with no priority), and the second set is used to configure a service card with a low priority.

[0170] For example, the first set of sending parameters is as follows:

[0171] sr-TransMax: Maximum number of SR transmissions, the default value is 8;

[0172] sr-ProhibitTimer: Minimum interval for sending SRs. The default value is 4 milliseconds.

[0173] The second set of send parameters is as follows:

[0174] sr-TransMax: Maximum number of SR transmissions, the default value is 32;

[0175] sr-ProhibitTimer: Minimum interval for sending SRs. The default value is 32 milliseconds.

[0176] In some embodiments, when a network device sends the sending parameters of a scheduling request to a terminal device through a first indication message, at least one of the sending parameters of the scheduling request may be sent. For example, the first indication message may only include the maximum number of SR sending times, or the first indication message may only include the minimum SR sending time interval, or the first indication message includes the maximum number of SR sending times and the minimum SR sending time interval.

[0177] In some embodiments, different sets of sending parameters may correspond to different identifiers. For example, the identifier of the first set of sending parameters is 1, and the identifier of the second set of sending parameters is 0. When the first indication information indicates to update the sending parameters, the first indication information may include the identifier of the sending parameters. For example, the first indication information includes: 0.

[0178] It should be understood that when the network device instructs the terminal device to update the transmission parameter by sending the parameter identifier, the terminal device is set with the value of the transmission parameter corresponding to the transmission parameter identifier, for example, as agreed in the protocol.

[0179] Optionally, when the network device indicates to send parameters, it may only indicate one parameter in the sending parameters. Therefore, when indicating through the identifier of the sending parameters, each parameter in the sending parameters also requires a corresponding identifier. For example, the identifier of the maximum number of SR sending times is 00, and the minimum SR sending time interval is 01. When the network device indicates to update all sending parameters, the first indication information may include: 0; when the network device indicates to update the maximum number of SR sending times, the first indication information may include: 00; when the network device indicates to update the minimum SR sending time interval, the first indication information may include: 01.

[0180] It should be understood that the identifier of the sending parameters can be set according to actual needs. For example, the identifier of the second set of sending parameters is 1, the identifier of the maximum number of SR sending times is 01, and the identifier of the minimum SR sending time interval is 00. The embodiment of the present application does not limit this.

[0181] In some embodiments, the first indication information may be carried in an RRC message or in downlink control information (DCI).

[0182] S502: The terminal device uses the updated value of the sending parameter to send a scheduling request to the network device.

[0183] In an embodiment of the present application, the terminal device receives the first indication information sent by the network device, and can obtain the sending parameters of the scheduling request sent by SIM2 according to the first indication information, and update the default sending parameters of the scheduling request sent by SIM2 based on the obtained sending parameters.

[0184] When the terminal device sends a scheduling request to the network device via the SIM card 2, the updated sending parameters may be used for sending.

[0185] The communication method provided in the embodiment of the present application is that when the network device determines that a high-priority business card occupies the uplink channel (a low-priority business card appears), the network device sends a first indication message to the terminal device corresponding to the low-priority business card, which is used to update the sending parameters of the scheduling request of the low-priority business card. The low-priority business card uses the updated sending parameters to send a scheduling request to the network device. Since the values ​​of the sending parameters of the updated scheduling request are more tolerant than those before the update, the probability of the low-priority business card successfully sending the SR can be improved, thereby reducing the probability of the terminal device triggering the RACH process, thereby improving the user experience.

[0186] exist Figure 5Based on the embodiment shown, when the network device instructs the low-priority service card to update the transmission parameters through the first instruction information, the transmission parameters of the low-priority service card set in the network device may include multiple sets, and the network device may select one set of parameters from the multiple sets of transmission parameters and send it to the terminal device. That is, Figure 5 S501 in the illustrated embodiment may include the following steps:

[0187] S5011. The network device determines the value of the sending parameter according to the bit error rate of the service data sent by the low-priority service card and / or the signal quality of the uplink signal transmitting the service data.

[0188] In the embodiment of the present application, a plurality of sets of values ​​of sending parameters corresponding to low-priority service cards are set in the network device.

[0189] For example, the values ​​of the sending parameters corresponding to three sets (A, B, C) of low-priority service cards are set in the network device as an example, as shown below:

[0190] A:

[0191] sr-TransMax: Maximum number of SR transmissions, the default value is 16;

[0192] sr-ProhibitTimer: Minimum interval for sending SRs. The default value is 16 milliseconds.

[0193] B:

[0194] sr-TransMax: Maximum number of SR transmissions, the default value is 32;

[0195] sr-ProhibitTimer: Minimum interval for sending SRs. The default value is 16 milliseconds.

[0196] C:

[0197] sr-TransMax: Maximum number of SR transmissions, the default value is 32;

[0198] sr-ProhibitTimer: Minimum interval for sending SRs. The default value is 32 milliseconds.

[0199] When the network device determines that the SIM card 2 of the terminal device is a low-priority service card, it can determine the values ​​of the transmission parameters that need to be sent from the above three sets of transmission parameter values.

[0200] In a possible implementation, the network device may determine the value of the sending parameter based on the signal quality of the uplink signal transmitted by the low-priority service card.

[0201] For example, the network device may determine a priority level based on the signal quality of an uplink signal transmitting service data, with different priority levels corresponding to different values ​​of the transmission parameter. The value of the transmission parameter is determined based on the priority level and a mapping relationship between the value of the transmission parameter and the priority level.

[0202] For example, priority level 1 corresponds to sending parameter A, priority level 2 corresponds to sending parameter B, and priority level 3 corresponds to sending parameter C.

[0203] Taking RSRP as an example, the signal quality of the uplink signal is RSRP. RSRP>-100dBm corresponds to priority level 1, RSRP>-120dBm corresponds to priority level 2, and RSRP>-140dBm corresponds to priority level 3.

[0204] The network device can measure the RSRP between itself and the terminal device and determine the value of the transmission parameter based on the measured RSRP and the above correspondence. For example, if the measured RSRP is -115dBm and the corresponding priority level is priority level 2, the network device can determine the value of the transmission parameter to be the value of transmission parameter B.

[0205] In a possible implementation, the network device may determine the value of the sending parameter based on a bit error rate of service data transmitted by a low-priority service card.

[0206] Network devices can determine the priority level based on the bit error rate of the transmitted service data. Different priority levels correspond to different values ​​of the transmission parameters. The values ​​of the transmission parameters are determined based on the priority level and the mapping relationship between the values ​​of the transmission parameters and the priority level.

[0207] For example, priority level 1 corresponds to sending parameter A, priority level 2 corresponds to sending parameter B, and priority level 3 corresponds to sending parameter C. Bit error rate > 20% corresponds to priority level 1, bit error rate > 30% corresponds to priority level 2, and bit error rate > 40% corresponds to priority level 3.

[0208] The network device can calculate the bit error rate (BER) of service data transmitted by the low-priority service card within a preset time period and determine the value of the transmission parameter based on the calculated BER and the aforementioned correspondence. For example, if the calculated BER is greater than 35% and the corresponding priority level is priority level 2, the network device can determine the value of the transmission parameter to be the value of transmission parameter B.

[0209] In a possible implementation, the network device may determine the value of the sending parameter based on the signal quality of the uplink signal transmitted by the low-priority service card and the bit error rate of the service data.

[0210] Network equipment can determine the priority level based on the signal quality of the uplink signal and the bit error rate of the transmitted service data. Different priority levels correspond to different transmission parameter values. The transmission parameter values ​​are determined based on the priority level and the mapping relationship between the transmission parameter values ​​and the priority level.

[0211] For example, priority level 1 corresponds to sending parameter A, priority level 2 corresponds to sending parameter B, and priority level 3 corresponds to sending parameter C. The signal quality and bit error rate of the uplink signal each correspond to a different weight value. The network device can determine the corresponding priority level based on the measured signal quality, calculated bit error rate, and their corresponding weight values, and determine the value of the sending parameter based on the priority level. For example, the network device normalizes the measured signal quality and calculated bit error rate, calculates the target value based on their respective weights, and determines the priority level based on the value range of each priority level, thereby determining the value of the sending parameter.

[0212] It should be understood that the correspondence between the bit error rate of the above-mentioned service data and / or the signal quality of the uplink signal transmitting the service data and the priority level, as well as the mapping relationship between the value of the transmission parameter and the priority level can be set based on actual needs, and the embodiments of the present application are not limited to this. The mapping relationship between the value of the above-mentioned transmission parameter and the priority level can be agreed upon in the protocol.

[0213] S5012. The network device sends first indication information to the terminal device.

[0214] In the embodiment of the present application, the specific implementation method of S5012 is the same as Figure 5 The specific implementation of S501 in the illustrated embodiment is similar and will not be repeated here.

[0215] In the above method, the network device can configure the corresponding sending parameters of the scheduling request to the low-priority service card of the terminal device based on the signal quality of the uplink signal of the transmitted service data and / or the bit error rate of the transmitted service data, which can improve the accuracy of the sending parameter configuration of the scheduling request.

[0216] Based on the above embodiment, when the low-priority service card of the terminal device uses the updated value of the sending parameter to send an SR to the network device, if the low-priority service card is restored to a normal service card, the value of the sending parameter also needs to be restored to the sending parameter before the update.

[0217] Reference Figure 6 , Figure 6 The flowchart of another communication method provided by the embodiment of the present application is exemplarily shown. Figure 6 Based on the embodiment shown, Figure 6As shown, the communication method of this embodiment includes:

[0218] S601: If the service priority of the second identity module card of the terminal device is not lower than the low service priority of the first identity module card, send fourth indication information to the terminal device. The fourth indication information is used to instruct the terminal device to restore the value of the sending parameter to the value before the update.

[0219] In some embodiments, when the terminal device recognizes that the high-priority service scheduled to be executed through SIM card 1 has ended, it can determine that the service priority of SIM card 2 is not lower than that of SIM card 1. At this time, after determining that SIM card 2 has been restored from a low-priority service card to a normal card, the terminal device can send fourth indication information to the network device.

[0220] In some embodiments, the fourth indication information may be carried in an RRC message or uplink control information (UCI).

[0221] In some embodiments, the network device may determine that the service priority of the second identity recognition module card of the terminal device is not lower than the low service priority of the first identity recognition module card based on the following method.

[0222] A first possible implementation manner: the network device determines based on indication information of the terminal device.

[0223] Correspondingly, in this implementation, the following steps may be further included before S601:

[0224] S600: The network device receives fifth indication information from the terminal device. The fifth indication information is used to indicate that the service priority of SIM card 2 is not lower than the low service priority of SIM card 1.

[0225] The fifth indication information may include a third identifier, and the third identifier is used to indicate that the service priority of SIM card 2 is not lower than that of SIM card 1. For example, the third identifier may be 0, 1, or equal.

[0226] A second possible implementation manner: the network device determines based on the signal quality between the network device and the terminal device.

[0227] Exemplarily, within a preset time, if the network device determines that the bit error rate of the service data sent by the terminal device through the second identity identification module card is less than or equal to the preset bit error rate, or the signal quality of the uplink signal sending the service data is less than or equal to the preset threshold, then it is determined that the service priority of the second identity identification module card is not lower than the low service priority of the first identity identification module card.

[0228] When the network device determines based on any of the above methods that the service priority of the second identity recognition module card of the terminal device is not lower than the low service priority of the first identity recognition module card, the network device sends fourth indication information to the terminal device.

[0229] In some embodiments, the fourth indication information includes a value of a transmission parameter, or the fourth indication information includes an identifier of a value of a transmission parameter. The specific implementation of the fourth indication information is similar to that of the first indication information and will not be repeated here.

[0230] In some embodiments, the terminal device records the value of the transmission parameter before the update, and the fourth indication information also includes only the fourth identifier, which is used to instruct the terminal device to restore the value of the transmission parameter to the value before the update. For example, the fourth identifier can be 0, 1, or recover, etc.

[0231] S602: Send a scheduling request to the network device using the restored value of the sending parameter.

[0232] In the embodiment of the present application, the terminal device receives the fourth indication information sent by the network device and can restore the sending parameters of the scheduling request sent by SIM2 to the state before the update according to the fourth indication information.

[0233] When the terminal device sends a scheduling request to the network device via the SIM card 2, the restored sending parameters may be used for sending.

[0234] The communication method of the embodiment of the present application has been described above. The following describes the apparatus for executing the above communication method provided in the embodiment of the present application. Those skilled in the art will understand that the method and apparatus can be combined and referenced with each other, and the relevant apparatus provided in the embodiment of the present application can execute the steps in the above communication method.

[0235] Figure 7 A schematic diagram of the structure of the communication device 70 provided in an embodiment of the present application is shown in FIG. Figure 7 Shown, including:

[0236] The sending module 701 is configured to send first indication information to the terminal device when it is determined that the service priority of the second identity recognition module card of the terminal device is lower than the service priority of the first identity recognition module card.

[0237] The first instruction information is used to instruct the terminal device to update the value of the sending parameter of the scheduling request of the second identity recognition module card, wherein the value of the updated sending parameter is greater than the value before the update.
