Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a communication method, device and storage medium. Background Art

[0002] In the existing immediate minimal drive test (MDT), the terminal needs to record the information of the handover failure and then report the handover failure information so that the network can analyze the cause of the handover failure.

[0003] Due to the emergence of multi-SIM terminals, for example, mobile phones that support dual-SIM calls at the same time, the functions of the two SIM cards may be limited when the two SIM cards are working at the same time. Although it is currently considered that the terminal can report information about temporary capacity limitations, the network side may not be able to obtain the limited capacity information in time, which may cause the terminal to switch to an inappropriate frequency. If such switching failure information is recorded, the network cannot accurately analyze the cause of the switching failure, that is, the accuracy of the network analysis is low. Summary of the invention

[0064] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0065] In this application, "at least one of the following items" or similar expressions refer to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can represent: a, b, c, a and b, a and c, b and c, or a, b and c, where each of a, b, and c can be an element itself or a set containing one or more elements.

[0066] In the present application, "at least one" means one or more, and "plurality" means two or more.

[0067] The first, second, etc. descriptions in this application are only used for illustration and distinction of the described objects, and have no order, nor do they represent a special limitation on the number of devices in the embodiments of this application, and cannot constitute any limitation on the embodiments of this application. For example, the first subscriber identity module (SIM) card and the second SIM card are only used to distinguish different SIM cards, and do not represent the difference in priority or importance of the two SIM cards.

[0068] In this application, "exemplary", "in some embodiments", "in other embodiments", etc. are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of the word "exemplary" is intended to present concepts in a concrete way.

[0069] Figure 1 A schematic diagram of the architecture of a communication system provided in an embodiment of the present application. Figure 1 As shown, the architecture includes a network device 101 and a terminal 102 .

[0070] The network equipment may include multiple cells. The terminal may switch from one cell to another (i.e., inter-cell switching), or switch from one channel in a cell to another channel (i.e., intra-cell switching). If a switching failure occurs during the cell switching process, the terminal needs to record the switching failure information and then report the switching failure information so that the network can analyze the cause of the switching failure. It should be noted that switching is sometimes also called synchronous reconfiguration.

[0071] If the terminal is equipped with multiple SIM cards, the functions of the multiple SIM cards may be limited when the multiple SIM cards work at the same time. Although it is currently considered that the terminal can report information about temporary limited capabilities, the network side may not be able to obtain the limited capability information in time, which may cause the terminal to switch to an inappropriate frequency. If such switching failure information is recorded, the network cannot accurately analyze the cause of the switching failure, that is, the accuracy of the network analysis is low.

[0072] Secondly, it is possible to introduce a priority or measurement sequence for measuring frequencies. This is an effective method for the network to guide connected terminals to measure frequencies. In a switching failure scenario, necessary information may need to be recorded so that the network can analyze the cause of the switching failure. If less information is recorded, the network may not be able to accurately analyze the cause of the switching failure, that is, the accuracy of the network analysis is low.

[0073] In order to solve the above technical problems, the present application provides a method for optimizing switching failure information, that is, the terminal generates switching failure information according to the specific situation, so that the content of the reported switching failure information is necessary and diverse, so that the network can accurately analyze the cause of the switching failure based on the switching failure information, thereby improving the accuracy of network analysis.

[0074] The technical solution shown in 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, and the same or displayed content will not be repeatedly described in different embodiments.

[0075] Figure 2 A communication method according to an embodiment of the present invention is provided. Figure 1 . See Figure 2 , the method comprising:

[0076] S201. The terminal generates switching failure information according to the capability status of the first SIM card.

[0077] In the embodiment of the present application, the terminal is provided with at least a first SIM card, and the first SIM card is in a connected state.

[0078] A capability status can be either restricted or unrestricted.

[0079] In a possible implementation manner, the restricted state means that the frequency band supported by the first SIM card is reduced, or the maximum number of multiple input multiple output (MIMO) layers on the supported frequency band is reduced.

[0080] The restricted state may also include other reduced capabilities, such as a reduction in the frequency band combinations supported by the first SIM card and a change in the measurement gap required by the first SIM card to detect inter-frequency.

[0081] More strictly speaking, the restricted state means that the software and hardware resources of the terminal that can be used when the terminal accesses the network with the first SIM card are restricted (compared to the capability information of the terminal reported to the network when the first SIM card initially accesses the network). This is caused by other SIM cards of the same terminal using the software and hardware resources of the terminal, or by the terminal being in an overheated state. For the sake of simplicity of description, the restricted state is expressed in this application as a reduction in the frequency band supported by the first SIM card, or a reduction in the maximum number of MIMO layers on the supported frequency band. In essence, it means that when the first SIM card accesses the network, the frequency band supported by the terminal is reduced, or the maximum number of MIMO layers on the supported frequency band is reduced, or it may be a reduction in the frequency band supported by the terminal and a reduction in the maximum number of MIMO layers on the supported frequency band.

[0082] The capability status of the first SIM card may be determined by the capabilities of at least two SIM cards that are in a connected state at the same time.

[0083] If the terminal is provided with three SIM cards, the SIM cards that are in the connected state at the same time may be at least two SIM cards; if there are two SIM cards that are in the connected state at the same time, the first SIM card is one of the two SIM cards that are in the connected state at the same time, and at this time, the capability state of the first SIM card is determined by the capabilities of the two SIM cards that are in the connected state at the same time; if there are three SIM cards that are in the connected state at the same time, the first SIM card is one of the three SIM cards that are in the connected state at the same time, and at this time, the capability state of the first SIM card is determined by the capabilities of the three SIM cards that are in the connected state at the same time.

[0084] Exemplarily, if the terminal is provided with two SIM cards, the frequency bands supported by SIM card A when working alone are new radio (NR) band and long term evolution (LTE) band, and the frequency bands supported by SIM card B when working alone are NR band, LTE band, 3G band and 2G band; if the two cards work at the same time, SIM card A can only work in the LTE band, and SIM card B can only work in the NR band. At this time, the capability status of SIM card A and SIM card B are both in a restricted state; if the two cards work at the same time, SIM card A can only work in the LTE band, the frequency band on which SIM card B can work is not reduced, and the maximum number of MIMO Layers supported on each band is not reduced. At this time, only the capability status of SIM card A is a restricted state.

[0085] In a possible implementation, the capability status of the first SIM card may be determined by the capability of at least one SIM card in a non-connected state that is receiving messages (eg, paging messages, system messages, multicast broadcast services, etc.).

[0086] Exemplarily, if the terminal is set with two SIM cards, the frequency bands supported by SIM card A when working alone are the NR band and the LTE band. If SIM card A is switching from the LTE band to the NR band, SIM card B is receiving a paging message through the NR band, resulting in a reduction in the NR band supported by SIM card A, it can be determined that the capability status of SIM card A is restricted.

[0087] In a possible implementation, the capability status of the first SIM card may be determined by the capability of at least one other SIM card that is in a connected state at the same time, and at least one SIM card that is in a non-connected state and is receiving a message.

[0088] In a possible implementation, when the terminal is only provided with the first SIM card, the capability status of the first SIM card may be determined by the software and hardware status of the terminal; for example, when the terminal is overheated, the capability status of the first SIM card may be a restricted state.

[0089] In a possible implementation, the terminal may determine the capability status of the first SIM card after the first SIM card fails to switch cells; or may determine the capability status of the first SIM card before or when receiving a switching instruction through the first SIM card.

[0090] In a possible implementation, when the capability state of the first SIM card is an unrestricted state, if a cell handover failure occurs in the first SIM card, the terminal may generate handover failure information; when the capability state of the first SIM card is a restricted state, if a cell handover failure occurs in the first SIM card, the terminal may not generate handover failure information (and thus not send handover failure information).

[0091] In a possible implementation, when the capability state of the first SIM card is a restricted state, if a cell handover failure occurs in the first SIM card, and the handover failure is not caused by capability limitation, handover failure information is generated; when the capability state of the first SIM card is a restricted state, if a cell handover failure occurs in the first SIM card, and the handover failure is caused by capability limitation, the handover failure information may not be generated (and thus the handover failure information is not sent), or the handover failure information is generated and the handover failure information indicates that the handover failure is caused by capability limitation.

[0092] In a possible implementation, the terminal may also be provided with a second SIM card, and the second SIM card is a SIM card that limits the capability of the first SIM card; when the capability state of the first SIM card is limited, if a switching instruction is received through the first SIM card, the connection of the second SIM card may be disconnected, and the first SIM card may be switched to a third cell (e.g., a target cell or a radio resource control (RRC) reconstructed cell), and if the first SIM card fails to switch during the switching process, switching failure information may be generated.

[0093] The second SIM card may be a SIM card that is in a connected state with the first SIM card, or the second SIM card may be a SIM card that is in a non-connected state and is receiving a paging message, a system message, or a multicast broadcast service.

[0094] The handover failure information may include relevant information of the cell where the handover failed, the source cell, etc.

[0095] In a possible implementation, the handover failure is caused by limited capability, specifically, the frequency band of the target cell to be handed over belongs to the frequency band of the terminal capability limited, that is, when the first SIM card accesses the network, it reports to the network that the terminal supports a certain frequency (Frequency) such as F1, so the network issues a handover command to the target cell on F1, but at this time, the first SIM card finds that the capability is limited, because the work of other SIM cards, such as the need to access the network or receive network messages, causes the first SIM card to be unable to use the frequency F1, so the first SIM card finds that the handover command cannot be executed, that is, the handover failure occurs, and the handover failure is caused by limited capability; or The maximum number of MIMO layers of the target cell included in the handover command cannot meet the requirement due to limited capabilities. For example, when the first SIM card accesses the network, it reports to the network that the maximum number of MIMO layers supported by the terminal on a certain frequency band is 8. Therefore, the network configures the terminal to switch to the maximum number of MIMO layers of 8 on the frequency band in the handover command. However, at this time, the first SIM card finds that the capability is limited because the work of other SIM cards, such as the need to access the network or receive network messages, causes the maximum number of MIMO layers of the first SIM card when working in the frequency band to be only 2. Therefore, the first SIM card finds that the handover command at this time cannot be applied, and the handover fails. The handover failure is caused by limited capabilities.

[0096] S202: The terminal sends a switching failure message to the network device.

[0097] In other words, the network device receives the switching failure information sent by the terminal.

[0098] The switching failure information sent by the terminal to the network device may be information composed of multiple switching failure information, each of which is generated by a switching failure; or may be single switching failure information.

[0099] After the handover fails, the terminal can send a handover failure message to the network device. For example, the terminal triggers RRC reconstruction after the handover fails. If the reconstruction is successful, the handover failure message can be sent to the cell that initiated the RRC reconstruction. If the terminal enters an idle state after the handover fails, it can wait until the next time it accesses the network to send the handover failure message to the network device.

[0100] The network device may analyze and determine the cause of the switching failure based on the received switching failure information.

[0101] exist Figure 2 In the illustrated embodiment, the terminal generates switching failure information according to the capability status of the first SIM card, the capability status is a restricted state or an unrestricted state, and sends the switching failure information to the network device. Since the switching failure information includes some necessary switching failure information, the network device can accurately analyze the cause of the switching failure according to the switching failure information, thereby improving the accuracy of network analysis.

[0102] exist Figure 2 Based on the embodiment shown below, combined with Figures 3 to 5 The communication method of the present application is described in detail.

[0103] Figure 3 A communication method according to an embodiment of the present invention is provided. Figure 2 . See Figure 3 , the method comprising:

[0104] S301. When a first SIM card fails to perform cell switching, the terminal determines a capability status of the first SIM card.

[0105] In the embodiment of the present application, the terminal is provided with at least a first SIM card, and the first SIM card is in a connected state.

[0106] If the capability state is not limited, execute S303.

[0107] If the capability status is limited, execute S302.

[0108] S302: Determine whether the switching failure is caused by limited capability.

[0109] If yes, the switching failure information is not sent, that is, the terminal does not record the switching failure information.

[0110] If not, execute S303.

[0111] S303: Generate switching failure information.

[0112] S304: The terminal sends a switching failure message to the network device.

[0113] Since the switching failure information caused by limited capacity is not reported to the network device, that is, the switching failure information received by the network device is caused by other reasons, the network device can correctly analyze the cause of the switching failure based on the switching failure information, thereby improving the accuracy of network analysis.

[0114] Figure 4 A communication method according to an embodiment of the present invention is provided. Figure 3 . See Figure 4 , the method comprising:

[0115] S401. When a first SIM card fails to perform cell switching, the terminal determines a capability status of the first SIM card.

[0116] In the embodiment of the present application, the terminal is provided with at least a first SIM card, and the first SIM card is in a connected state.

[0117] If the capability state is not limited, execute S404.

[0118] If the capability status is limited, execute S402.

[0119] S402: Determine whether the switching failure is caused by limited capability.

[0120] If yes, execute S403.

[0121] If not, execute S404.

[0122] S403: Generate second switching failure information.

[0123] The second handover failure information includes reason information, and the reason information indicates that the capability of the first SIM card is limited. That is, the handover failure information at this time indicates that the handover failure is caused by the limited capability of the first SIM card, and the limited capability of the first SIM card is caused by the need for other SIM cards of the terminal to work, such as being in a connected state to communicate with the network, or needing to receive system messages, paging messages, and multicast broadcast services of the network.

[0124] S404: Generate first switching failure information.

[0125] S404: The terminal sends first switching failure information or second switching failure information to the network device.

[0126] The network device receives the switching failure information. If the switching failure information indicates that the switching failure is caused by the limited capability of the first SIM card, the network device can analyze why the limited capability information was not obtained in time according to the switching failure information, or analyze whether the limited capability information of the terminal was not updated in time during the switching process, so as to avoid issuing inappropriate switching instructions later.

[0127] Figure 5 A communication method according to an embodiment of the present invention is provided. Figure 4 . See Figure 5 , the method comprising:

[0128] S501. A network device sends a switching instruction to a first SIM card of a terminal.

[0129] In an embodiment of the present application, the terminal is provided with multiple SIM cards, the first SIM card is any one of the multiple SIM cards in a connected state, the capability of the first SIM card (referring to the terminal capability applied by the first SIM card) may be reduced due to the influence of at least one second SIM card, the second SIM card may be a SIM card in a connected state among the multiple SIM cards or a SIM card in a non-connected state among the multiple SIM cards that is receiving a paging message, a system message, or a multicast broadcast service, and the first SIM card is different from the second SIM card.

[0130] In other words, the terminal receives the switching instruction sent by the network device through the first SIM card.

[0131] The switching instruction may instruct the first SIM card to switch to the first cell.

[0132] S502: The terminal determines the capability status of the first SIM card.

[0133] If the capability state is not limited, execute S504.

[0134] If the capability status is limited, execute S503.

[0135] Among them, S502 and S501 can be executed simultaneously.

[0136] S503: disconnect the second SIM card, and switch the first SIM card to the third cell. If the switching process fails, execute S504.

[0137] The second SIM card may be a SIM card among the multiple SIM cards that limits the capability of the first SIM card.

[0138] The third cell may be an RRC reconstruction cell or the first cell.

[0139] S504: Generate switching failure information.

[0140] Because the terminal first determines whether the switching failure will be caused by limited capability before performing cell switching, if so, the terminal can temporarily eliminate the limited capability so that the first SIM card can smoothly switch to the first cell, or even if the switching fails, the switching failure is avoided to be caused by limited capability. In this case, the switching failure information generated does not include the switching failure information caused by limited capability. Therefore, the network device can correctly analyze the cause of the switching failure based on the switching failure information, thereby improving the accuracy of network analysis.

[0141] The above embodiment illustrates the process of optimizing the handover failure information when the terminal has multiple SIM cards in a connected state at the same time. Figure 6 Describe in detail the optimization process of switching information for other scenarios.

[0142] Figure 6 A communication method according to an embodiment of the present invention is provided. Figure 5 . See Figure 6 , the method comprising:

[0143] S601. After a terminal fails in performing cell handover, the terminal generates handover failure information, where the handover failure information includes a measurement result at a first frequency point.

[0144] In the embodiment of the present application, the terminal may be provided with one SIM card or multiple SIM cards.

[0145] The first frequency point may be a frequency point whose measurement order is lower than a preset threshold or the first frequency point may be a frequency point whose priority is higher than a preset priority.

[0146] The measurement order can be 1, 2, 3, 4, etc. The smaller the value, the earlier the measurement order.

[0147] The number of the first frequency points may be one or more.

[0148] When the number of the first frequency point is one, the first frequency point refers to a frequency point with the highest measurement order or a frequency point with the highest priority.

[0149] In a possible implementation manner, the handover failure information may further include at least one of the following items:

[0150] a relationship between the frequency of the first cell and the first frequency, the first cell being a target cell for handover;

[0151] The relationship between the frequency of the second cell and the first frequency, the second cell is an RRC reconstruction cell.

[0152] When the number of first frequency points is one, the relationship between the frequency point of the first cell and the first frequency point may mean that the frequency point of the first cell is the same as or different from the first frequency point; when the number of first frequency points is multiple, the relationship between the frequency point of the first cell and the first frequency point may mean that the frequency point of the first cell is one of the first frequency points or the frequency point of the first cell does not belong to any of the first frequency points.

[0153] When the number of the first frequency points is one, if the frequency point of the first cell is the same as the first frequency point, it can be indicated that the first cell is a cell on the first frequency point.

[0154] When the number of first frequency points is one, the relationship between the frequency point of the second cell and the first frequency point may mean that the frequency point of the second cell is the same as or different from the first frequency point; when the number of first frequency points is multiple, the relationship between the frequency point of the second cell and the first frequency point may mean that the frequency point of the second cell is one of the first frequency points or the frequency point of the second cell does not belong to any of the first frequency points.

[0155] When the number of the first frequency points is one, if the frequency point of the second cell is the same as the first frequency point, it can be indicated that the second cell is a cell on the first frequency point.

[0156] In a possible implementation, before generating switching failure information, the terminal may also receive measurement frequency information sent by the network device, where the measurement frequency information includes information of multiple hetero-frequency points and the priority or measurement order of at least one hetero-frequency point among the multiple hetero-frequency points, where the first frequency point is a frequency point among the multiple hetero-frequency points.

[0157] That is, the network equipment can first be configured to measure multiple hetero-frequency points, as well as the priority or measurement order of at least one hetero-frequency point among the multiple hetero-frequency points. After receiving the measurement frequency point information, the terminal conducts measurement and reports a measurement report that meets the reporting conditions. The network equipment usually initiates a switching process based on the measurement report. If a switching failure occurs during the switching process, the terminal needs to preferentially record the measurement results of the first frequency point, and can also record whether the target cell for switching is a cell on the first frequency point. If RRC reconstruction occurs after the switching failure, it is also necessary to record whether the RRC reconstructed cell is a cell on the first frequency point.

[0158] Exemplarily, if the network device is configured with 5 heterofrequency frequency points, namely frequency 1, frequency 2, frequency 3, frequency 4 and frequency 5, and the measurement order of frequency 1, frequency 3 and frequency 4 is configured as 2, 1, and 3 respectively (that is, the measurement order is to measure frequency 3 first, then frequency 1, and then frequency 4); when a switching failure occurs, the terminal generates a switching failure message, and the switching failure message may include the measurement result of the first frequency point, the first frequency point is the frequency point with a measurement order lower than 3, that is, the first frequency point is frequency 3 and frequency 1, and the switching failure message may include the measurement results of frequency 3 and frequency 1; the switching failure information may also include whether the target cell of the switching is a cell on frequency 3 or frequency 1; if RRC reconstruction occurs after the switching failure, the switching failure information may also include whether the RRC reconstructed cell is a cell on frequency 3 or frequency 1.

[0159] When configuring the measurement order or priority of the frequency points, the network device may set the measurement order of the frequency point where the cell to which the terminal is most likely to switch is located to be the first, or set its priority to be the highest.

[0160] For frequencies with priority or measurement order, the terminal will measure them first.

[0161] In addition to the above information, the handover failure information may also include relevant information of the cell where the handover failed, the source cell, etc.

[0162] S602: The terminal sends a switching failure message to the network device.

[0163] In other words, the network device receives the switching failure information sent by the terminal.

[0164] The network device determines the cause of the switching failure based on the switching failure information.

[0165] For example, after receiving the switching failure information, the network device can analyze whether the measurement order or priority of the measurement frequency points are set reasonably. If the target cell to be switched is not on the first frequency point, the measurement order or priority of the frequency points may be set incorrectly (that is, the measurement order or priority of the frequency point where the target cell to be switched is located is later or has a lower priority, or the measurement order or priority of the frequency point where the target cell to be switched is located is not set), and the switching failure may be caused by measurement reporting delay.

Figure 7 The communication device 10 is applied to a terminal, the terminal is provided with at least a first SIM card, and the first SIM card is in a connected state, and the device 10 includes:

[0167] A generating module 11, configured to generate switching failure information according to a capability status of the first SIM card, wherein the capability status is a restricted state or an unrestricted state;

[0168] The sending module 12 is used to send the switching failure information.

[0169] In a possible implementation manner, the restricted state means that the frequency band supported by the first SIM card is reduced, or the maximum number of MIMO layers on the supported frequency band is reduced.

[0170] In a possible implementation, the generating module 12 is specifically configured to:

[0171] When the capability state is unrestricted, if the first SIM card fails to switch, a switching failure message is generated;

[0172] When the capability state is the limited state, if a handover failure occurs to the first SIM card, and the handover failure is not caused by the limited capability, handover failure information is generated.

[0173] In a possible implementation, the generating module 12 is specifically configured to:

[0174] When the capability state is in an unrestricted state, if the first SIM card fails to switch, first switching failure information is generated;

[0175] When the capability state is the limited state, if the first SIM card fails to switch, and the switching failure is caused by the limited capability, then second switching failure information is generated, the second switching failure information includes reason information, and the reason information indicates that the capability of the first SIM card is limited;

[0176] The switching failure information is the first switching failure information or the second switching failure information.

[0177] In a possible implementation, the generating module 12 is specifically configured to:

[0178] When the capability state is limited, the second SIM card is disconnected and the first SIM card is switched to the third cell. If the first SIM card fails to switch during the switching process, switching failure information is generated. The second SIM card is the SIM card among the multiple SIM cards that limits the capability of the first SIM card.
