Description

Technical Field

[0001] The present application relates to the field of intelligent terminal technology, and in particular to a multi-card joint scheduling method, device and readable storage medium. Background Art

[0002] With the rapid development of science and technology, the emergence of multi-card terminals (User Equipment, UE) has been sought after by most people. Multi-card terminals can support the simultaneous insertion of multiple Subscriber Identity Module (SIM) cards, allowing the terminal to transmit data through the data links provided by multiple SIM cards, making it convenient for users to access the Internet. Dual-card UE is currently the most common type of multi-card UE. While it brings great convenience to users, it also has some problems.

[0003] At present, when a dual-card UE establishes a connection with the base station corresponding to each of the dual cards, the base station will send parameters to the UE for the corresponding card, such as discontinuous reception (DRX) parameters, measurement parameters, and pre-synchronization parameters. The parameters sent by different base stations are often different. For scenarios that the UE cannot control autonomously, such as DRX paging scenarios and connected discontinuous reception duration (CDRX Onduration) scenarios, the UE can only perform periodic fixed position scheduling according to different parameters (such as DRX parameters) sent by the base stations corresponding to the dual cards.

[0004] For scenarios that the UE can control autonomously, such as measurement scheduling, pre-synchronization scheduling scenarios, etc., the UE can autonomously select the scheduling position. At present, the UE performs independent scheduling according to different parameters (such as measurement parameters and pre-synchronization parameters) sent by the base station corresponding to the dual cards, that is, the measurement scheduling and pre-synchronization scheduling positions of the UE for the dual cards (such as card 0 and card 1) are independently selected. For example, the measurement and pre-synchronization operation position of card 0 is the periodic position closest to the paging position or Onduration position of card 0, and the measurement and pre-synchronization operation position of card 1 is the periodic position closest to the paging position or Onduration position of card 1. These schedulings that can be autonomously controlled by the UE are all independently scheduled by the UE based on the parameters corresponding to each of the dual cards, and no joint scheduling will be performed. If the dual cards of the UE reside in different cells, the paging positions or Onduration positions of the dual cards are likely to be different. The independent selection of measurement and pre-synchronization of the dual cards is likely to cause the UE to be in a long-term awake state, which consumes high power.

[0005] Therefore, the present application provides a multi-card joint scheduling method, which can reduce the power consumption of UE. Summary of the invention

[0006] The embodiments of the present application provide a multi-card joint scheduling method, device and readable storage medium, which can reduce the wake-up time of UE and reduce the power consumption of UE.

[0007] The present application is introduced below from different aspects. It should be understood that the implementation methods and beneficial effects of the following different aspects can be referenced to each other.

[0008] In a first aspect, the present application provides a multi-card joint scheduling method, which is applied to a terminal device, wherein N user identification module SIM cards are arranged in the terminal device, and the method comprises: determining a time window of each SIM card in the M SIM cards; the start and end times of the time window are respectively a first moment and a second moment, the first moment is the stop moment of the discontinuous reception DRX activation period of each SIM card, and the second moment is one of one or more pre-synchronization moments corresponding to the DRX activation period; the M SIM cards are SIM cards in the N SIM cards; based on the time windows of the M SIM cards, determining the moment for pre-synchronization of K SIM cards in the N SIM cards; the K SIM cards include the M SIM cards, M is a positive integer less than or equal to N, and N and K are both integers greater than or equal to 2.

[0009] For the current multi-card terminal, for the autonomously controlled measurement and pre-synchronization scheduling scenarios, the measurement and pre-synchronization scheduling positions of each card are independently selected, resulting in a long UE wake-up time and high power consumption. In the embodiment of the present application, the UE can determine the time window of each SIM card in one or more SIM cards based on the wake-up parameters of the multiple SIM cards (such as paging parameters, OnDuration parameters, measurement parameters and pre-synchronization parameters, etc.), and then determine the time for the corresponding SIM card and other SIM cards to perform pre-synchronization based on these time windows, so as to realize the joint scheduling of pre-synchronization between multiple cards, minimize the wake-up time of the UE, and reduce power consumption.

[0010] In a possible implementation manner, the second moment is a pre-synchronization moment that is closest to the DRX activation period.

[0011] In the embodiment of the present application, the width of the time window determined by the UE is the smallest, so that when the subsequent UE determines the time for pre-synchronization of the SIM card corresponding to the time window and other SIM cards based on these time windows, the UE wake-up time can be reduced to a greater extent, saving power consumption.

[0012] In a possible implementation manner, the M SIM cards include a first SIM card, and determining, based on the time windows of the M SIM cards, the times at which K SIM cards among the N SIM cards are pre-synchronized includes:

[0013] The first pre-synchronization moment is determined as the moment when the target SIM card performs pre-synchronization; the first pre-synchronization moment is a pre-synchronization moment among one or more pre-synchronization moments associated with the target SIM card that overlaps with the time window of the first SIM card, and the target SIM card is any one of the K SIM cards.

[0014] In the embodiment of the present application, the UE can determine the time for pre-synchronization of multiple SIM cards only through the time window of a single SIM card. If one or more pre-synchronization times corresponding to the target SIM card overlap with the time window, the pre-synchronization time overlapping with the time window can be determined as the time for pre-synchronization of the target SIM card, which realizes simple logic and high efficiency.

[0015] In a possible implementation manner, the M SIM cards include a first SIM card, and determining, based on the time windows of the M SIM cards, the times at which K SIM cards among the N SIM cards are pre-synchronized includes:

[0016] The second pre-synchronization moment is determined as the moment when the target SIM card performs pre-synchronization; the one or more pre-synchronization moments associated with the target SIM card do not overlap with the time window of the first SIM card, the second pre-synchronization moment is the pre-synchronization moment closest to the third moment among the one or more pre-synchronization moments associated with the target SIM card before the third moment, the third moment is the stop moment of the DRX activation period of the target SIM card, and the target SIM card is any one of the K SIM cards.

[0017] In the embodiment of the present application, the UE can determine the time for pre-synchronization of multiple SIM cards only through the time window of a single SIM card. If one or more pre-synchronization times corresponding to the target SIM card do not overlap with the time window, the pre-synchronization time closest to the DRX activation period can be found before the DRX activation period of the target SIM card, and it can be used as the time for pre-synchronization of the target SIM card, which realizes simple logic and high efficiency.

[0018] In a possible implementation manner, determining the time window of each SIM card in the M SIM cards includes:

[0019] Acquire DRX parameters and reference signal parameters corresponding to the M SIM cards; the DRX parameters are used to indicate the stop time of the DRX activation period of each SIM card in the M SIM cards, and the reference signal parameters are used to indicate one or more pre-synchronization moments of each SIM card in the M SIM cards;

[0020] A time window for each SIM card in the M SIM cards is determined based on the DRX parameter and the reference signal parameter.

[0021] In an embodiment of the present application, the UE may first obtain some parameters related to the wake-up of each SIM card, such as DRX parameters (including paging parameters and Onduration parameters, etc.) and reference signal parameters (including measurement parameters and pre-synchronization parameters, etc.), and determine the time windows of some or all SIM cards in the UE based on these parameters, so as to ensure that the time for pre-synchronization of the SIM card can be accurately determined later.

[0022] In a possible implementation manner, the M SIM cards include a first SIM card and a second SIM card, and determining the time window of each SIM card in the M SIM cards includes:

[0023] Determine a first time window of the first SIM card and a second time window of the second SIM card;

[0024] The determining, based on the time windows of the M SIM cards, the time at which K SIM cards among the N SIM cards are pre-synchronized comprises:

[0025] Determine the time for pre-synchronization of the K SIM cards based on the first time window and the second time window.

[0026] In the embodiment of the present application, the UE can determine the time for pre-synchronization of multiple SIM cards through the time windows of two SIM cards. Introducing a larger number of time windows can increase the possibility of overlapping between one or more pre-synchronization moments corresponding to other SIM cards and the time windows, and is more likely to achieve the purpose of reducing the UE wake-up time and reducing power consumption.

[0027] In a possible implementation manner, the K SIM cards include the first SIM card and the second SIM card, and determining the time for pre-synchronization of the K SIM cards based on the first time window and the second time window includes:

[0028] Determine whether one or more pre-synchronization moments associated with the second SIM card overlap with the first time window, and whether one or more pre-synchronization moments associated with the first SIM card overlap with the second time window, and obtain a determination result;

[0029] A time for pre-synchronization of the first SIM card and the second SIM card is determined based on the determination result.

[0030] In the embodiment of the present application, when the UE determines the time for pre-synchronization of the two SIM cards through the time windows of the two SIM cards, it can first determine whether one or more pre-synchronization times corresponding to each of the two SIM cards overlap with the time window of the other party, and then determine the time for pre-synchronization of the two SIM cards according to the judgment situation, so as to ensure the accuracy of the joint scheduling.

[0031] In a possible implementation manner, determining, based on the determination result, a time for pre-synchronizing the first SIM card and the second SIM card includes:

[0032] If one or more pre-synchronization moments associated with the second SIM card overlap with the first time window, and one or more pre-synchronization moments associated with the first SIM card overlap with the second time window, a moment for pre-synchronization of the first SIM card and the second SIM card is determined based on a size of the first time window and a size of the second time window.

[0033] In the embodiment of the present application, when the UE determines the time when the two SIM cards are pre-synchronized through the time windows of the two SIM cards, if one or more pre-synchronization times corresponding to each of the two SIM cards overlap with the time windows of the other party, the UE can determine the time when they are pre-synchronized according to the time window sizes of the two SIM cards.

[0034] In a possible implementation manner, determining the time for pre-synchronizing the first SIM card and the second SIM card based on the size of the first time window and the size of the second time window includes:

[0035] If the first time window is smaller than the second time window, determining the pre-synchronization time associated with the first SIM card in the first time window as the time when the first SIM card performs pre-synchronization, and determining the pre-synchronization time associated with the second SIM card in the first time window as the time when the second SIM card performs pre-synchronization; or,

[0036] If the first time window is larger than the second time window, the pre-synchronization time associated with the second SIM card in the second time window is determined as the time when the second SIM card performs pre-synchronization, and the pre-synchronization time associated with the first SIM card in the second time window is determined as the time when the first SIM card performs pre-synchronization.

[0037] In the embodiment of the present application, when the UE determines the time when the two SIM cards are pre-synchronized through the time windows of the two SIM cards, if one or more pre-synchronization times corresponding to each of the two SIM cards overlap with the time window of the other party, the UE can determine the time when the two SIM cards are pre-synchronized according to the smaller time window of the two time windows corresponding to the two SIM cards, thereby further reducing the wake-up time of the UE and reducing the power consumption of the UE to a greater extent.

[0038] In a possible implementation manner, determining, based on the determination result, a time for pre-synchronizing the first SIM card and the second SIM card includes:

[0039] If one or more pre-synchronization moments associated with the second SIM card overlap with the first time window, and one or more pre-synchronization moments associated with the first SIM card do not overlap with the second time window, the pre-synchronization moment associated with the first SIM card in the first time window is determined as the moment when the first SIM card performs pre-synchronization, and the pre-synchronization moment associated with the second SIM card in the first time window is determined as the moment when the second SIM card performs pre-synchronization; or,

[0040] If one or more pre-synchronization moments associated with the second SIM card do not overlap with the first time window, and one or more pre-synchronization moments associated with the first SIM card overlap with the second time window, the pre-synchronization moment associated with the first SIM card in the second time window is determined as the moment when the first SIM card performs pre-synchronization, and the pre-synchronization moment associated with the second SIM card in the second time window is determined as the moment when the second SIM card performs pre-synchronization.

[0041] In the embodiment of the present application, when the UE determines the time when the two SIM cards are pre-synchronized through the time windows of the two SIM cards, if one or more pre-synchronization times corresponding to each of the two SIM cards overlap with only one of the time windows of the other party, the UE can determine the time when the two SIM cards are pre-synchronized according to the overlapping time windows, thereby reducing the wake-up time of the UE and reducing the power consumption of the UE.

[0042] In a possible implementation manner, determining, based on the determination result, a time for pre-synchronizing the first SIM card and the second SIM card includes:

[0043] If one or more pre-synchronization moments associated with the second SIM card do not overlap with the first time window, and one or more pre-synchronization moments associated with the first SIM card do not overlap with the second time window, the pre-synchronization moment associated with the first SIM card in the first time window is determined as the moment when the first SIM card performs pre-synchronization, and the pre-synchronization moment associated with the second SIM card in the second time window is determined as the moment when the second SIM card performs pre-synchronization.

[0044] In the embodiment of the present application, when the UE determines the time when the two SIM cards are pre-synchronized through the time windows of the two SIM cards, if one or more pre-synchronization times corresponding to each of the two SIM cards do not overlap with the time windows of the other party, the UE can determine the time when they are pre-synchronized according to their respective time windows, thereby ensuring the feasibility of the overall solution.

[0045] In a possible implementation, the start and end times of the first time window are a fourth moment and a fifth moment, the fourth moment is the stop time of the DRX activation period of the first SIM card, and the fifth moment is the moment closest to the fourth moment among one or more pre-synchronization moments corresponding to the DRX activation period of the first SIM card; the start and end times of the second time window are a sixth moment and a seventh moment, the sixth moment is the stop time of the DRX activation period of the second SIM card, and the seventh moment is the moment closest to the sixth moment among one or more pre-synchronization moments corresponding to the DRX activation period of the second SIM card.

[0046] In the embodiment of the present application, the widths of the two time windows determined by the UE are both minimal, so that when the subsequent UE determines the time for pre-synchronization of the corresponding SIM card and other SIM cards based on these time windows, the UE wake-up time can be reduced to a greater extent, saving power consumption.

[0108] It can be understood that in the embodiment of the present application, "used for indication" may include direct indication and indirect indication, and may also include explicit indication and implicit indication. When describing "a certain indication information is used to indicate A" or "indication information of A", it may include that the indication information directly indicates A or indirectly indicates A, but it does not mean that the indication information must carry A. The information indicated by a certain information (such as the indication information of the coefficient described below) is called information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association relationship between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be realized by means of the arrangement order of each information agreed in advance (such as specified by the protocol), thereby reducing the indication overhead to a certain extent. At the same time, the common parts of each information can also be identified and uniformly indicated to reduce the indication overhead caused by indicating the same information separately. In addition, the specific indication method can also be various existing indication methods, such as but not limited to the above indication methods and various combinations thereof. The specific details of various indication methods can refer to the prior art, and will not be repeated herein. As described above, for example, when it is necessary to indicate multiple information of the same type, different indication methods may occur. In the specific implementation process, the required indication method can be selected according to specific needs. The embodiment of the present application does not limit the selected indication method. In this way, the indication method involved in the embodiment of the present application should be understood as covering various methods that can enable the party to be indicated to know the information to be indicated. The information to be indicated can be sent as a whole, or it can be divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different. The specific sending method is not limited in this application. Among them, the sending period and / or sending time of these sub-information can be pre-defined, for example, pre-defined according to the protocol, or can be configured by the transmitting end device by sending configuration information to the receiving end device. Among them, the configuration information can, for example, but not limited to, include one or a combination of at least two of radio resource control signaling, MAC layer signaling and physical layer signaling.

[0135] The above content explains the communication system architecture that can be applied to the embodiments of the present application. In order to better understand the technical solutions of the embodiments of the present application, several terms or nouns related to the present application are briefly introduced below to facilitate understanding by technical personnel in this field.

[0136] 1. Discontinuous Reception (DRX)

[0137] Since data packets are bursty, when there is no data transmission, the UE can reduce power consumption by stopping receiving PDCCH, which is DRX (discontinuous reception). DRX is a function introduced to save power for UE and is configured by the radio resource control (RRC) layer. By controlling the DRX function, the UE can be controlled to monitor the cell radio network temporary identifier (C-RNTI), transmission power control-physical uplink control channel-RNTI (TPC-PUCCH-RNTI), transmission power control-physical uplink shared channel-RNTI (TPC-PUSCH-RNTI) and the like on the physical downlink control channel (PDCCH). In the RRC connected state, if the RRC layer configures the DRX function for the media access control (MAC) layer, that is, the UE has the DRX function in the connected state (CDRX), then the UE can monitor the PDCCH intermittently at the physical layer; otherwise, the UE must monitor the PDCCH continuously. The DRX function in the RRC idle state is the well-known paging function, that is, the network side sends a paging message to wake up the UE and put the UE into an active period.

[0138] 2. CDRX

[0139] By configuring CDRX, a UE in a connected state can periodically enter a sleep mode at certain times and not monitor PDCCH subframes. It can wake up from the sleep mode only when it needs to monitor, thus saving power. The basic mechanism of CDRX is to configure a DRX cycle for a UE in an RRC connected state (RRC_CONNECTED state). A DRX cycle can include two parts, one is Onduration, where the UE monitors and receives PDCCH (i.e., activation period), and the other is Opportunity for DRX, where the UE does not monitor PDCCH to reduce power consumption (i.e., sleep period).

[0140] 3. Measurement and Pre-synchronization

[0141] Before the UE is paged or enters the Onduration, that is, before the UE enters the activation period, it is generally necessary to perform measurement and pre-synchronization first.

[0142] For measurement, the UE can obtain the channel status of the cell through measurement, such as Radio Resource Management (RRM) measurement, to ensure the communication quality of the UE during the DRX activation period.

[0143] For pre-synchronization, due to the time and frequency deviation caused by the crystal oscillator frequency deviation and the mobile Doppler of the mobile terminal, a pre-synchronization process is usually required, that is, the time and frequency deviation is adjusted through the synchronization signal. For example, in the paging process, a pre-synchronization process is required in advance to achieve the adjustment of the time and frequency deviation.

[0144] In an embodiment of the present application, measurement and pre-synchronization can be performed together, that is, the pre-synchronization moment mentioned later is the moment when pre-synchronization can be performed, and it is also the moment when measurement can be performed. It is understandable that measurement and pre-synchronization can also be performed separately. For how the UE determines the moment when its SIM card performs measurement, please refer to the relevant description of the moment when the UE determines the moment when its SIM card performs pre-synchronization in the following text. Exemplarily, for a 4G network, the reference signal used for measurement and pre-synchronization may be a cell-specific reference signal (Cell-specific Reference Signal, CRS); for a 5G network, the reference signal used for measurement and pre-synchronization may be a periodic synchronization signal block (Synchronization Signal and PBCH block, SSB) signal. It is understandable that in addition to the above-mentioned CRS and SSB signals, the reference signal used for measurement and pre-synchronization may also be a tracking reference signal (Tracking Reference Signal, TRS) or other physical downlink reference signals. The reference signal used for measurement and pre-synchronization is generally sent periodically by the base station, and the UE can independently choose at which periodic position (or time) to receive the reference signal for measurement and pre-synchronization.

[0145] First, the technical problems to be solved by this application are analyzed and proposed. At present, for the measurement scheduling and pre-synchronization scheduling scenarios that can be controlled autonomously by multi-card terminals, the measurement scheduling and pre-synchronization scheduling positions of each card are independently selected. For example, the measurement and pre-synchronization positions of each card are directly bound to their respective paging or Onduration positions. Assuming that the multi-card terminal is a dual-card terminal, the following takes the case where both cards are in IDLE standby as an example. Please refer to Figure 3 , Figure 3 The figure is a schematic diagram of a scheduling cycle of dual-card standby, wherein, if the modem is in NR mode, the reference signal used for measurement and pre-synchronization is SSB, and if the modem is in LTE mode, the reference signal used for measurement and pre-synchronization is CRS.

[0146] Modem0 and Modem1 are both in IDLE standby mode, with a paging cycle of 1.28s. Each card starts measurement and pre-synchronization every two paging cycles. The measurement and pre-synchronization of the dual cards both look for the cycle position closest to each paging cycle as the operation position for measurement and pre-synchronization. The current waveform of the dual card wake-up is shown in the figure below. Figure 3 As shown in the figure, S1 is the wake-up time from measurement and pre-synchronization to paging of modem1, S0 is the wake-up time from measurement and pre-synchronization to paging of Modem0, P0 is the wake-up time for paging of Modem0 alone, and P1 is the wake-up time for paging of Modem1 alone. When UE wakes up, as long as one modem wakes up, all the components related to the UE need to wake up. The longer the wake-up time, the higher the power consumption of the UE. Figure 3 The scheduling method shown has the problem of long UE wake-up time and high power consumption.

[0147] Let's take the example of one card in IDLE standby and one card in CDRX standby. Figure 4 , Figure 4 This is another scheduling cycle diagram for dual-SIM standby. The measurement and pre-synchronization of Modem0 and Modem1 are also scheduled independently. Modem0 is in IDLE standby, with a paging cycle of 0.64s. Measurement and pre-synchronization are required for each paging cycle. Modem1 is in CDRX standby, with an Onduration cycle of 0.16s. Pre-synchronization and measurement are performed once every two Onduration cycles. The power consumption current waveform of the UE is as follows: Figure 4 As shown, the UE wake-up time is long and the power consumption is high.

[0148] Let's take the case where both cards are in CDRX standby mode as an example. Figure 5 , Figure 5 This is another schematic diagram of the scheduling cycle of dual-card standby. The measurement and pre-synchronization of Modem0 and Modem1 are also scheduled independently. Modem0 is in CDRX standby, and the Onduration cycle is 0.32s. Measurement and pre-synchronization are required in each Onduration cycle. Modem1 is in CDRX standby, and the Onduration cycle is 0.16s. Pre-synchronization and measurement are performed once in two Onduration cycles. The power consumption current waveform of the UE is as follows Figure 5 As shown, the UE wake-up time is long and the power consumption is high.

[0149] To this end, the present application proposes a multi-card joint scheduling method, device and readable storage medium, which can reduce the wake-up time of UE and reduce power consumption. Specifically, the UE can determine the time window of each SIM card in one or more SIM cards based on the wake-up parameters of each of the multiple SIM cards (such as paging parameters, Onduration parameters, measurement parameters and pre-synchronization parameters, etc.), and then determine the time for the corresponding SIM card and other SIM cards to perform measurement and pre-synchronization based on these time windows, so as to realize the joint scheduling of measurement and pre-synchronization between multiple cards, minimize the wake-up time of UE and reduce power consumption.

[0150] For ease of understanding, the technical solution provided by this application will be described below in conjunction with more drawings.

[0151] In this application, unless otherwise specified, the same or similar parts between various embodiments or implementations can refer to each other. In each embodiment of this application, and each implementation method / implementation method / implementation method in each embodiment, if there is no special explanation and logical conflict, the terms and / or descriptions between different embodiments and each implementation method / implementation method / implementation method in each embodiment are consistent and can be referenced to each other. The technical features in different embodiments and each implementation method / implementation method / implementation method in each embodiment can be combined to form new embodiments, implementation methods, implementation methods, or implementation methods according to their inherent logical relationships. The implementation methods of this application described below do not constitute a limitation on the scope of protection of this application.

[0152] See also Figure 6 , Figure 6 is a flow chart of a multi-card joint scheduling method provided in an embodiment of the present application, which can be applied to the above Figure 1 UE in the above Figure 1 The UE in can be used to support and execute Figure 6 The method flow steps are shown in FIG. Figure 6 As shown, the method includes but is not limited to the following steps:

[0153] S601: Determine a time window for each SIM card among M SIM cards.

[0154] Among them, N SIM cards can be set in the UE, N is an integer greater than or equal to 2, that is to say, the UE can be a UE supporting dual cards, or a UE supporting more SIM cards. The UE can determine the time windows corresponding to some or all of the N SIM cards (such as M SIM cards), that is, M is a positive integer less than or equal to N. The start and end time of the time window of each SIM card are the first moment and the second moment respectively. The first moment is the stop time of the discontinuous reception DRX activation period of each SIM card, and the second moment is one of the one or more pre-synchronization moments corresponding to the DRX activation period. See Figure 7a , Figure 7a This is a schematic diagram of the relationship between a DRX activation period and a pre-synchronization moment provided in an embodiment of the present application, wherein the stop moment of DRX activation period 1 is T1, the stop moment of DRX activation period 2 is T2, and the stop moment of DRX activation period 3 is T3. The one or more pre-synchronization moments corresponding to the DRX activation period refer to all pre-synchronization moments before the activation period and after the previous activation period. For example, the one or more pre-synchronization moments corresponding to DRX activation period 2 are the measurement and pre-synchronization moment 2 between DRX activation period 1 and DRX activation period 2 (at this time, the measurement and pre-synchronization can be performed together), and the one or more pre-synchronization moments corresponding to DRX activation period 3 are the measurement and pre-synchronization moment 3 between DRX activation period 2 and DRX activation period 3. Taking DRX activation period 2 as an example, the start and end time of the time window can be T2 and tn, or T2 and t1, or T2 and t2, which are not listed here one by one. It should be noted that, Figure 7a Only the relationship between the DRX activation period and the pre-synchronization time of a certain SIM card in the UE is shown, and other SIM cards have their own corresponding DRX activation periods and pre-synchronization times.

[0155] S602: Determine, based on the time windows of the M SIM cards, the times at which K SIM cards among the N SIM cards are to be pre-synchronized.

[0156] Among them, the above-mentioned K SIM cards include the above-mentioned M SIM cards, M is a positive integer less than or equal to N, and K is an integer greater than or equal to 2, that is, the UE can determine the time when the M SIM cards perform pre-synchronization based on the time window of the M SIM cards, and can also determine the time when other SIM cards perform pre-synchronization, so as to achieve joint scheduling of measurement and pre-synchronization between multiple cards, minimize the wake-up time of the UE, and reduce power consumption.

[0157] Optionally, the start and end time of the time window may be the stop time of the DRX activation period and the pre-synchronization time closest to the DRX activation period among one or more pre-synchronization times corresponding to the DRX activation period. That is, the first time is the stop time of the DRX activation period, and the second time is the pre-synchronization time closest to the DRX activation period (or the first time). Figure 7a The width of the time window determined in this way is the smallest, which can reduce the UE wake-up time to a greater extent and save power consumption.

[0158] For ease of understanding, the method provided in the present application is briefly described by taking a multi-card UE as a dual-card UE as an example. The dual-card UE is provided with two SIM cards, that is, N is equal to 2.

[0159] In a possible implementation, the UE may determine only the time window of one of the dual SIM cards, and determine the time for the dual SIM cards to perform pre-synchronization based on the time window, that is, the UE may determine the time for multiple SIM cards to perform pre-synchronization only through the time window of a single SIM card. Figure 6 In the method shown, M may be equal to 1, and K may be equal to 2. Exemplarily, two SIM cards (such as card 0 and card 1) are provided in the UE, and the UE may determine the time window 1 of card 1 (corresponding to the first SIM card), and then determine the moment when card 0 and card 1 perform measurement and pre-synchronization based on the time window 1. Optionally, when determining the moment when card 0 and card 1 perform measurement and pre-synchronization, the UE may refer to the following method, and the UE may determine the first pre-synchronization moment as the moment when the target SIM card performs pre-synchronization; the first pre-synchronization moment is a pre-synchronization moment among one or more pre-synchronization moments associated with the target SIM card that overlaps with the time window of the first SIM card, and the target SIM card is any one of the K SIM cards.

[0160] like Figure 7b As shown, because paging and pre-synchronization are periodic, for ease of understanding, only one cycle (such as Figure 7bThe paging and pre-synchronization of dual cards (the part within the dotted box in the figure) are illustrated, where the width of time window 1 of card 1 (i.e. Modem1) is S1ms, and the start and end times of time window 1 are the stop time of paging (corresponding to the DRX activation period) and the pre-synchronization time closest to the paging (i.e. pre-synchronization time 3n), respectively. For card 0, among the multiple pre-synchronization times associated with card 0 (i.e. Modem0), pre-synchronization time 1 overlaps with time window 1, so the UE can determine pre-synchronization time 1 as the time for card 0 to perform measurement and pre-synchronization, instead of selecting the pre-synchronization time n closest to the paging position as the time for card 0 to perform measurement and pre-synchronization; for card 1, among the multiple pre-synchronization times associated with card 1, pre-synchronization time 3n overlaps with time window 1 (because pre-synchronization time 3n itself is one end of the start and end times of time window 1), so the UE can determine pre-synchronization time 3n as the time for card 1 to perform measurement and pre-synchronization. Compared to Figure 3 In the prior art shown in FIG. 1 , the wake-up time of the UE is reduced from (S1+S0) ms to (S1+S0-C) ms, and the time during which the UE operating current is at a higher value is changed from (S1+S0) ms to (S1+S0-C) ms, that is, the wake-up time of the UE can be reduced by Cms, where Cms is the time interval from the pre-synchronization moment n of the card 0 to the paging start moment.

[0161] It should be noted that, because the measurement and pre-synchronization moments are close to the DRX activation period (such as paging), and the UE needs a certain time (for example, 20ms or 30ms, not specifically limited here) to fall asleep again after being awakened for pre-synchronization, a wake-up window will be formed between the pre-synchronization moment n of card 0 and the paging, and the distance between the paging of card 0 and card 1 is sufficient (because the paging cycle is often in the second level), and the UE can fall asleep again after paging card 1, and then wake up when paging card 0. Optionally, the start and end time of the time window 1 of the above card 1 can also be the stop time of paging (corresponding to the DRX activation period) and other pre-synchronization moments (i.e., before the pre-synchronization moment 3n, other pre-synchronization moments after the last paging, not shown in the figure).

[0162] Above Figure 7bIt is shown that there is an overlap between the multiple pre-synchronization moments associated with card 0 and time window 1. If the multiple pre-synchronization moments associated with card 0 do not overlap with time window 1, the UE can regard the pre-synchronization moment n as the moment for card 0 to measure and pre-synchronize, and determine the pre-synchronization moment 3n as the moment for card 1 to measure and pre-synchronize. In other words, if one or more pre-synchronization moments associated with the target SIM card do not overlap with the time window of the first SIM card, the UE can determine the second pre-synchronization moment as the moment for the target SIM card to pre-synchronize; the second pre-synchronization moment is the pre-synchronization moment closest to the third moment among the one or more pre-synchronization moments associated with the target SIM card before the third moment, the third moment is the starting moment of the DRX activation period of the target SIM card, and the target SIM card is any one of the K SIM cards.

[0163] Exemplarily, the UE may also determine the time window 0 of card 0 (corresponding to the first SIM card), and then determine the time for card 0 and card 1 to perform measurement and pre-synchronization based on the time window 0. Figure 7c As shown, reference Figure 7c In the dotted box, the width of time window 0 of card 0 (i.e., Modem0) is S0ms. The start and end times of time window 0 are respectively the stop time of paging (corresponding to the DRX activation period) and the pre-synchronization time closest to paging (i.e., pre-synchronization time n). For card 1, among the multiple pre-synchronization times associated with card 1, the pre-synchronization time a overlaps with time window 0. Therefore, the UE can determine the pre-synchronization time a as the time for card 1 to perform measurement and pre-synchronization. In this example, card 1 is configured to perform measurement and pre-synchronization once every 2 paging cycles. At this time, changing the pre-synchronization position from pre-synchronization time 3n to pre-synchronization time a is equivalent to moving the pre-synchronization position from the previous paging cycle to the next paging cycle. For card 0, among the multiple pre-synchronization times associated with card 0, the pre-synchronization time n overlaps with time window 0. Therefore, the UE can determine the pre-synchronization time n as the time for card 0 to perform measurement and pre-synchronization. Compared to Figure 3 In the prior art shown in FIG. 1 , the wake-up time of the UE is reduced from (S1+S0) ms to (S1+S0-D) ms, and the time during which the UE operating current is at a higher value is changed from (S1+S0) ms to (S1+S0-D) ms, that is, the wake-up time of the UE can be reduced by Dms, where Dms is the time interval from the pre-synchronization moment 3n of the card 1 to the paging start moment.

[0164] It should be noted that when the UE has the DRX function in the idle state, the DRX activation period refers to paging (corresponding to IDLE standby), and when the UE has the DRX function in the connected state, the DRX activation period refers to Onduration (corresponding to CDRX standby). For dual-card UEs, both cards can be configured with DRX in the idle state, or one card can be configured with DRX in the idle state and the other card can be configured with DRX in the connected state, or both cards can be configured with DRX in the connected state. Figure 7b and Figure 7c What is shown is an example of DRX configuration in which both dual cards are in idle state. For ease of understanding, the measurement and pre-synchronization scheduling methods for dual cards in the other two configurations are briefly described below.

[0165] like Figure 7d As shown, card 0 is configured for DRX in idle state, and card 1 is configured for DRX in connected state. For example, the paging cycle of card 0 is 0.64s, and the Onduration cycle (i.e., CDRX interval) of card 1 is 0.16s. Figure 7d In the dotted box, the width of time window 1 of card 1 (i.e. Modem1) is S1ms, and the start and end times of time window 1 are respectively the stop time of Onduration (corresponding to the DRX activation period) and the pre-synchronization time closest to the paging (i.e. pre-synchronization time 3n). For card 0, among the multiple pre-synchronization times associated with card 0 (i.e. Modem0), pre-synchronization time 1 overlaps with time window 1, so the UE can determine pre-synchronization time 1 as the time for card 0 to perform measurement and pre-synchronization, instead of selecting the pre-synchronization time n closest to the paging position as the time for card 0 to perform measurement and pre-synchronization; for card 1, among the multiple pre-synchronization times associated with card 1, pre-synchronization time 3n overlaps with time window 1, so the UE can determine pre-synchronization time 3n as the time for card 1 to perform measurement and pre-synchronization. Compared to Figure 4 In the prior art shown in FIG. 1 , the wake-up time of the UE is reduced from (S1+S0) ms to (S1+S0-C) ms, and the time during which the UE operating current is at a higher value is changed from (S1+S0) ms to (S1+S0-C) ms, that is, the wake-up time of the UE can be reduced by Cms, where Cms is the time interval from the pre-synchronization moment n of the card 0 to the paging start moment.

[0166] For example Figure 7e As shown, both card 0 and card 1 are configured with DRX in the connected state. For example, the Onduration period (i.e., CDRX interval) of card 0 and card 1 is 0.16s. Figure 7dIn the dotted box, the width of time window 1 of card 1 (i.e. Modem1) is S1ms, and the start and end times of time window 1 are respectively the stop time of Onduration (corresponding to the DRX activation period) and the pre-synchronization time closest to the paging (i.e. pre-synchronization time 3n). For card 0, among the multiple pre-synchronization times associated with card 0 (i.e. Modem0), pre-synchronization time 1 overlaps with time window 1, so the UE can determine pre-synchronization time 1 as the time for card 0 to perform measurement and pre-synchronization, instead of selecting the pre-synchronization time n closest to the paging position as the time for card 0 to perform measurement and pre-synchronization; for card 1, among the multiple pre-synchronization times associated with card 1, pre-synchronization time 3n overlaps with time window 1, so the UE can determine pre-synchronization time 3n as the time for card 1 to perform measurement and pre-synchronization. Compared to Figure 5 In the prior art shown in FIG. 1 , the wake-up time of the UE is reduced from (S1+S0) ms to (S1+S0-C) ms, and the time during which the UE operating current is at a higher value is changed from (S1+S0) ms to (S1+S0-C) ms, that is, the wake-up time of the UE can be reduced by Cms, where Cms is the time interval from the pre-synchronization moment n of the card 0 to the paging start moment.

[0167] In a possible implementation, the UE may determine the time windows corresponding to the dual SIM cards respectively, and then determine the time for the dual SIM cards to perform pre-synchronization based on the two time windows. Figure 6 In the method shown, M may be equal to 2, and K may be equal to 2. Exemplarily, two SIM cards (such as card 0 and card 1) are provided in the UE, and the UE may determine the time window 1 (corresponding to the first time window) of card 1 (corresponding to the first SIM card) and the time window 0 (corresponding to the second time window) of card 0 (corresponding to the second SIM card), and then determine the time for card 0 and card 1 to perform measurement and pre-synchronization based on time window 0 and time window 1, respectively. Optionally, when determining the time for card 0 and card 1 to perform measurement and pre-synchronization, the UE may first determine whether one or more pre-synchronization moments associated with card 0 overlap with time window 1, and whether one or more pre-synchronization moments associated with card 1 overlap with time window 0, and then determine the time for card 0 and card 1 to perform measurement and pre-synchronization based on the judgment result. That is, the UE may first determine whether one or more pre-synchronization moments associated with the second SIM card overlap with the first time window, and whether one or more pre-synchronization moments associated with the first SIM card overlap with the second time window, to obtain a judgment result; and then determine the time for the first SIM card and the second SIM card to perform pre-synchronization based on the judgment result.

[0168] Exemplarily, the above judgment results may include the following three situations: situation 1 is that one or more pre-synchronization moments associated with each of the dual cards overlap with the time window corresponding to the other card; situation 2 is that one or more pre-synchronization moments associated with only one of the dual cards overlap with the time window corresponding to the other card; situation 3 is that one or more pre-synchronization moments associated with each of the dual cards do not overlap with the time window corresponding to the other card. In different situations, the selection of dual-card pre-synchronization moments of the UE will be different, and you can refer to the following for Figure 8 A description of the process schematic is shown.

[0169] For example, when one or more pre-synchronization moments associated with each of the dual cards overlap with the time window corresponding to the other party (i.e., situation 1), the UE can determine the time for the dual cards to perform pre-synchronization according to the size of the time window corresponding to the dual cards, that is, if one or more pre-synchronization moments associated with the second SIM card overlap with the first time window, and one or more pre-synchronization moments associated with the first SIM card overlap with the second time window, the UE can determine the time for the first SIM card and the second SIM card to perform pre-synchronization based on the size of the first time window and the size of the second time window. Optionally, the UE can select a pre-synchronization moment within a smaller time window as the time for the dual cards to perform pre-synchronization. For example, if the first time window is smaller than the second time window, the UE can determine the pre-synchronization moment associated with the first SIM card in the first time window (i.e., the moment overlapping with the first time window) as the time for the first SIM card to perform pre-synchronization, and determine the pre-synchronization moment associated with the second SIM card in the first time window (i.e., the moment overlapping with the first time window) as the time for the second SIM card to perform pre-synchronization. It should be noted that when a SIM card has multiple associated pre-synchronization moments that overlap with the time window of another SIM card, the UE can select the pre-synchronization moment that is closer to the DRX activation period of the SIM card as the moment for pre-synchronization of the SIM card to ensure the accuracy of synchronization during the DRX activation period of the SIM card. Understandably, if the first time window is larger than the second time window, the UE can select the pre-synchronization moment within the second time window as the moment for pre-synchronization of the first SIM card and the second SIM card, which will not be repeated here.

[0170] like Fig. 9As shown, see the part in the dotted box, the width of the time window 0 of card 0 (i.e. Modem0) is S0ms, the start and end time of the time window 0 are the stop time of the card 0 paging (corresponding to the DRX activation period) and the pre-synchronization time closest to the paging (i.e. pre-synchronization time n), the width of the time window 1 of card 1 (i.e. Modem1) is S1ms, the start and end time of the time window 1 are the stop time of the card 1 paging (corresponding to the DRX activation period) and the pre-synchronization time closest to the paging (i.e. pre-synchronization time 3n), wherein the pre-synchronization time 1 of card 0 overlaps with the time window 1 of card 1, and the pre-synchronization time a of card 1 overlaps with the time window 0 of card 0. The UE can determine the time for card 0 and card 1 to perform pre-synchronization based on the size of the time window 0 and the size of the time window 1. For example, S1 is greater than S0, that is, the time window 1 of card 1 is greater than the time window 0 of card 0. The UE can determine the time for the dual cards to perform pre-synchronization in a smaller time window, and then the UE uses the pre-synchronization time n as the time for card 0 to perform pre-synchronization, and uses the pre-synchronization time a as the time for card 1 to perform pre-synchronization. Different from the prior art, in which card 0 performs pre-synchronization at pre-synchronization time n, card 1 performs pre-synchronization at pre-synchronization time 3n, and the wake-up time of the UE is (S0+S1) ms, the embodiment of the present application can reduce the wake-up time of the UE to (S0+S1-D) ms, that is, the time when the UE working current is at a higher value is changed from (S1+S0) ms to (S1+S0-D) ms, and Dms is the time interval from the pre-synchronization time 3n of card 1 to the paging start time.

[0171] When one or more pre-synchronization moments associated with only one of the dual SIM cards overlap with the time window corresponding to the other SIM card (i.e., situation 2), the UE may determine the time for the dual SIM cards to perform pre-synchronization from the time window corresponding to the other SIM card. That is, if one or more pre-synchronization moments associated with the second SIM card overlap with the first time window, and one or more pre-synchronization moments associated with the first SIM card do not overlap with the second time window, the pre-synchronization moment associated with the first SIM card in the first time window is determined as the time for the first SIM card to perform pre-synchronization, and the pre-synchronization moment associated with the second SIM card in the first time window is determined as the time for the second SIM card to perform pre-synchronization; or, if one or more pre-synchronization moments associated with the second SIM card do not overlap with the first time window, and one or more pre-synchronization moments associated with the first SIM card overlap with the second time window, the pre-synchronization moment associated with the first SIM card in the second time window is determined as the time for the first SIM card to perform pre-synchronization, and the pre-synchronization moment associated with the second SIM card in the second time window is determined as the time for the second SIM card to perform pre-synchronization. Exemplarily, if the pre-synchronization time of card 0 is within time window 1 and the pre-synchronization time of card 1 is not within time window 0, both cards perform measurement and pre-synchronization at the pre-synchronization time within time window 1.

[0172] If one or more pre-synchronization moments associated with each of the two cards do not overlap with the time window corresponding to the other party (i.e., case three), the UE can determine the time for the two cards to perform pre-synchronization from the time windows corresponding to the two cards, that is, if one or more pre-synchronization moments associated with the second SIM card do not overlap with the first time window, and one or more pre-synchronization moments associated with the first SIM card do not overlap with the second time window, the pre-synchronization moment associated with the first SIM card in the first time window is determined as the time for the first SIM card to perform pre-synchronization, and the pre-synchronization moment associated with the second SIM card in the second time window is determined as the time for the second SIM card to perform pre-synchronization. Similar to the prior art, the UE selects the pre-synchronization moment closest to the DRX activation period of the two cards as the time for the two cards to perform pre-synchronization. Exemplarily, if the pre-synchronization moment of card 0 is not within time window 1, and the pre-synchronization moment of card 1 is not within time window 0, the two cards perform measurement and pre-synchronization in their respective windows, that is, the two cards respectively search for the pre-synchronization moment closest to their respective paging (or Onduration) for measurement and pre-synchronization.

[0173] Optionally, the start and end time of the time window of any of the above-mentioned SIM cards may be any one of the stop time of the DRX activation period of the SIM card and one or more pre-synchronization moments corresponding to the DRX activation period. Further, the start and end time of the time window may be the stop time of the DRX activation period and the pre-synchronization moment closest to the DRX activation period among the one or more pre-synchronization moments corresponding to the DRX activation period. Exemplarily, the start and end time of the first time window is the fourth moment and the fifth moment, the fourth moment is the start time of the DRX activation period of the first SIM card, and the fifth moment is the moment closest to the fourth moment among the one or more pre-synchronization moments corresponding to the DRX activation period of the first SIM card; the start and end time of the second time window is the sixth moment and the seventh moment, the sixth moment is the start time of the DRX activation period of the second SIM card, and the seventh moment is the moment closest to the sixth moment among the one or more pre-synchronization moments corresponding to the DRX activation period of the second SIM card.

[0174] It should be noted that the above is only explained by taking the multi-card UE as a dual-card UE as an example. The dual cards can both be NR standards, or both cards can be LTE standards, or one of the dual cards can be NR and the other can be LTE, or other standards other than LTE and NR. At the same time, the standby corresponding to the dual cards can both be IDLE standby, or both can be CDRX standby, or one card can be IDLE standby and the other can be CDRX standby, or it can be further extended to other sleep wake-up scenarios. It should also be noted that the multi-card UE in the embodiment of the present application can also be a three-card UE, a four-card UE or even a UE that supports more SIM cards, which is not specifically limited here. Taking a three-card UE (including card 0, card 1 and card 2) as an example for a simple explanation, the UE can only determine the time window of one of the three SIM cards, and then determine the time for the three cards to pre-synchronize based on the time window. The specific determination method can refer to the above Figure 7b-7e The relevant description will not be repeated here.

[0175] In addition, the UE may also choose to determine the time windows corresponding to multiple SIM cards among the three cards (it may be the time windows for determining two of the SIM cards or the time windows for determining three SIM cards), and then determine the time for pre-synchronization of the three cards based on these time windows. The specific determination method may refer to the following methods.

[0176] For example, if the UE only determines the time window of two SIM cards, the UE can first refer to the above Figure 8 In the method in, determine the overlap between the pre-synchronization time and the time window of the two SIM cards. If they overlap, a smaller time window can be selected to determine the pre-synchronization time of the two cards (refer to Figure 8Corresponding to case 1); then check whether there is a moment overlapping with the smaller time window in one or more pre-synchronization moments of the third SIM card. If yes, the UE can select the overlapping moment as the moment for pre-synchronization of the third SIM card. If no, the UE can select the moment closest to its DRX activation period in the pre-synchronization moment of the third SIM card as the moment for pre-synchronization of the third SIM card. Alternatively, in the case where the pre-synchronization moments of the two SIM cards overlap with the time windows, the UE can first check whether the pre-synchronization moment of the third SIM card overlaps with the two time windows respectively. If both overlap, the UE can determine the moment for pre-synchronization of the three SIM cards based on the smaller one of the two time windows; if only one of the time windows overlaps, the UE can determine the moment for pre-synchronization of the three SIM cards based on this time window; if none overlap, the UE autonomously selects the moment for pre-synchronization of the third SIM card, and determines the moment for pre-synchronization of the corresponding two SIM cards based on the two time windows. Alternatively, the UE can also autonomously select the moment for pre-synchronization of card 2 without jointly considering the judgment of the other two SIM cards to make a decision.

[0177] For the case where only one of the pre-synchronization time and time window of two SIM cards overlaps (such as Figure 8 Corresponding to situation 2), for example, the pre-synchronization moment of card 0 overlaps with the time window 1 of card 1, and the pre-synchronization moment of card 1 does not overlap with the time window 0 of card 0. The UE can determine the time for pre-synchronization of the two SIM cards (card 0 and card 1) based on time window 1, and then determine whether one or more pre-synchronization moments of the third SIM card (card 2) overlap with time window 1. If so, the UE can select the overlapping moment as the time for pre-synchronization of card 2. If not, the UE can select the moment closest to its DRX activation period among the pre-synchronization moments of card 2 as the time for pre-synchronization of card 2. Alternatively, the UE can also independently select the time for pre-synchronization of card 2 without jointly considering the judgment of the other two SIM cards to make a decision.

[0178] For the case where there is no overlap between the pre-synchronization time and the time window of the two SIM cards (such as Figure 8 Corresponding to situation three), for example, the pre-synchronization time of card 0 does not overlap with the time window 1 of card 1, and the pre-synchronization time of card 1 does not overlap with the time window 0 of card 0. The UE can refer to the above Figure 8The UE determines the time when Card 0 and Card 1 are pre-synchronized according to the relevant description of the third situation. As for the time when the third SIM card (Card 2) is pre-synchronized, it can be determined whether one or more pre-synchronization moments of Card 2 overlap with time window 0 and time window 1 respectively. If so, the UE can select the overlapping moment as the time when the third SIM card is pre-synchronized. If not, the UE can select the moment of the pre-synchronization moment of the third SIM card that is closest to its DRX activation period as the time when the third SIM card is pre-synchronized. No further details are given here.

[0179] In addition, the UE can also determine the time windows of the three SIM cards, and then determine the time for the three SIM cards to be pre-synchronized based on the three time windows. For how the UE determines the time for the three SIM cards to be pre-synchronized based on the three time windows, refer to the above Figure 8 The related ideas and descriptions about the UE determining the time for two SIM cards to perform pre-synchronization based on two time windows are not further expanded here. In addition, for how multiple cards in a four-card UE jointly determine the time for multiple SIM cards to perform pre-synchronization, reference can be made to the related descriptions in the determination process of the dual-card UE and the three-card UE, which are not further expanded here.

[0180] It should be noted that before the UE determines the time window of each SIM card among the M SIM cards in the above step S601, it can first obtain various wake-up parameters (such as paging parameters, Onduration parameters, measurement parameters and pre-synchronization parameters, etc.) from the base station side corresponding to each SIM card, and then know the period, offset and duration and other information corresponding to the paging or Onduration of each SIM card, as well as the period, offset and duration and other information corresponding to the measurement and pre-synchronization of each SIM card. The UE can determine the time window and pre-synchronization moment corresponding to each SIM card based on this information, and finally determine the moment for pre-synchronization of each SIM card based on the overlap of each time window and the pre-synchronization moment, so as to realize the joint scheduling of measurement and pre-synchronization between multiple SIM cards, minimize the wake-up time of the UE, and achieve the purpose of reducing power consumption. It should also be noted that the above Figure 6 The method shown can be run when the UE is turned on, or when the UE undergoes cell switching (various parameters may change), or can be run by the UE according to a certain period, and no specific limitation is made here.

[0181] The above content describes the method provided by the present application. In order to facilitate the implementation of the above scheme of the embodiment of the present application, the embodiment of the present application also provides corresponding devices or equipment.

[0182] The present application divides the functional modules of the device according to the above method embodiment. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated modules can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the present application is schematic and is only a logical function division. There may be other division methods in actual implementation. The device of the embodiment of the present application will be described below in conjunction with the accompanying drawings.

[0183] See also Fig.10 , Fig.10 is a schematic diagram of a communication device provided in an embodiment of the present application. The communication device 10 can be used to implement the above Figure 6 The method embodiments involved can therefore also achieve the beneficial effects possessed by the above-mentioned method embodiments.

[0184] like Fig.10 As shown, the communication device 10 may include a first determining unit 100 and a second determining unit 101. Exemplarily, when the communication device 10 is used to implement the above Figure 6 When the functions involved in the communication device 10 are as follows Figure 1 The terminal shown may also be a module (such as a chip) applied to the terminal. The functions of each unit are as follows:

[0185] The first determining unit 100 is configured to determine a time window of each SIM card in the M SIM cards; the start and end times of the time window are respectively a first moment and a second moment, the first moment is a stop moment of a discontinuous reception DRX activation period of each SIM card, and the second moment is one of one or more pre-synchronization moments corresponding to the DRX activation period; the M SIM cards are SIM cards in the N SIM cards;

[0186] The second determining unit 101 is used to determine, based on the time windows of the M SIM cards, a time at which K SIM cards among the N SIM cards perform pre-synchronization; the K SIM cards include the M SIM cards, M is a positive integer less than or equal to N, and N and K are both integers greater than or equal to 2.

[0187] In a possible implementation manner, the second moment is a pre-synchronization moment that is closest to the DRX activation period.

[0188] In a possible implementation manner, the M SIM cards include a first SIM card, and the second determining unit 101 is specifically configured to:

[0189] The first pre-synchronization moment is determined as the moment when the target SIM card performs pre-synchronization; the first pre-synchronization moment is a pre-synchronization moment among one or more pre-synchronization moments associated with the target SIM card that overlaps with the time window of the first SIM card, and the target SIM card is any one of the K SIM cards.
