[0002] Dual-SIM mobile phones have gradually become the mainstream in the mobile phone market.

[0028] To enable those of ordinary skill in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that such used data may be interchanged under appropriate circumstances so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0030] Figure 1 Flow schematic diagram of a method for eliminating bandwidth interference of dual SIM cards provided by an embodiment of the present disclosure.

[0031] As Figure 1 shown, this method for eliminating bandwidth interference of dual SIM cards, which is executed by a terminal device or a chip, includes the following steps:

[0032] S101, if the terminal device is in a target scenario, determine at least one radio resource control (RRC) element from the first RRC element of the first user SIM card and the second RRC element of the second user SIM card as the target RRC, where the target scenario is that the terminal device switches from dual SIM dual standby (DSDS) to dual SIM dual active (DSDA) scenario, or the terminal device enters the DSDA scenario.

[0033] It should be noted that the terminal device (User Equipment, hereinafter referred to as UE) can be in multiple scenarios. For example, the terminal device is in the Dual Sim Dual Active (DSDA) scenario. Another example is that the terminal device is in the process of switching from Dual Sim Dual Standby (DSDS) to the DSDA scenario. The present disclosure can pre-determine the target scenario in which the terminal device is located.

[0034] Among them, for the DSDA scenario, the services of the two SIM cards often cannot be carried out concurrently. For the DSDS scenario, the services of the two SIM cards can often be carried out concurrently, but there may be a problem of mutual interference between the uplink and downlink bandwidths during the concurrent service process.

[0035] Among them, the first user card and the second user card are Subscriber Identity Module (SIM) cards, which are integrated circuit cards held by mobile users of the global mobile communication system.

[0036] It should be noted that the present disclosure does not limit the types of the first user card and the second user card, and they can be selected according to actual situations.

[0037] Optionally, the first user card and the second user card can be e-SIM cards, Micro-SIM cards, Nano-SIM cards, etc.

[0038] Among them, the Radio Resource Control (RRC) network element can perform radio resource management, control, and scheduling.

[0039] It should be noted that the terminal device can use the first user card and communicate based on the first network, and the terminal device can use the second user card and communicate based on the second network. Among them, the first network and the second network can be the same or different.

[0040] Among them, the first network and the second network can be the 5th-Generation Mobile Communication Technology (5G) network, the 4th-Generation Mobile Communication Technology (4G) network.

[0041] For example: the first user card communicates based on the 5G network, and the second user card communicates based on the 4G network; Another example is that the first user card communicates based on the 5G network, and the second user card communicates based on the 5G network.

[0042] In an embodiment of the present disclosure, if the terminal device is in a target scenario, at least one RRC network element can be determined from the first RRC network element of the first user card and the second RRC network element of the second user card as the target RRC.

[0043] For example, if the terminal device is in a scenario of switching from DSDS to DSDA, the target RRC is the first RRC network element.

[0044] For example, if the terminal device is in the DSDA scenario, the target RRC network elements include the first RRC network element and the second RRC network element.

[0045] S102, send indication information to the target RRC, where the indication information is used to instruct the target RRC to report the interference bandwidth of the target user card to the base station, and the target user card is determined based on the target RRC.

[0046] It should be noted that if the first user card is the primary card and the second user card is the secondary card, when the primary card and the secondary card perform concurrent services, there may be a problem of interference in the bandwidth between the serving cell of the primary card and the serving cell of the secondary card. For example: there is interference between the primary cell of the primary card and the primary cell of the secondary card, there is interference between the primary cell of the primary card and the secondary cell of the secondary card, there is interference between the secondary cell of the primary card and the secondary cell of the secondary card, there is interference between the secondary cell of the primary card and the primary cell of the secondary card. That is to say, there may be an overlap problem in the bandwidth between the serving cell (primary cell and / or secondary cell) of the primary card and the serving cell (primary cell and / or secondary cell) of the secondary card, resulting in the inability to perform concurrent services for the primary card and the secondary card.

[0047] In an embodiment of the present disclosure, through the provided method for eliminating bandwidth interference of dual cards, when the terminal device is in a target scenario, the bandwidth interference of the dual cards can be eliminated through the indication information, and concurrent processing of dual-card services can be achieved.

[0048] In an embodiment of the present disclosure, the target user card can be determined based on the target RRC.

[0049] Optionally, if the target RRC is the first RRC network element, the target user card is the second user card corresponding to the second RRC network element; if the target RRC network elements include the first RRC network element and the second RRC network element, the target user card corresponding to the first RRC network element is the second user card, and the target user card corresponding to the second RRC network element is the first user card.

[0050] For example, if the terminal device is in a scenario of switching from DSDS to DSDA, the target RRC is the first RRC network element, and the target user card is the second user card. The terminal device sends indication information to the first RRC network element, and the indication information is used to instruct the first RRC network element to report the interference bandwidth of the second user card to the base station. Correspondingly, after receiving the interference bandwidth of the second user card, the first RRC network element can switch from the current cell to a target cell outside the interference bandwidth for avoidance, and then the second RRC network element can perform services, achieving concurrent service execution of the dual cards.

[0051] In the embodiments of the present disclosure, if the target RRC network element includes a first RRC network element and a second RRC network element, the target user card corresponding to the first RRC network element is the second user card, and the target user card corresponding to the second RRC network element is the first user card.

[0052] For example, if the target RRC network element includes a first RRC network element and a second RRC network element, the target user card corresponding to the first RRC network element is the second user card, and the target user card corresponding to the second RRC network element is the first user card. The terminal device sends indication information (including the interference bandwidth of the second user card) to the first RRC network element and sends indication information (including the interference bandwidth of the first user card) to the second RRC network element. Correspondingly, after the first RRC network element receives the interference bandwidth of the second user card and the second RRC network element receives the interference bandwidth of the first user card, the first RRC network element can switch from the current cell to a target cell outside the interference bandwidth of the second user card, and the second RRC network element can switch from the current cell to a target cell outside the interference bandwidth of the first user card. Then, the first RRC network element and the second RRC network element can continue to perform services, achieving concurrent service execution of the dual cards.

[0053] A method for eliminating bandwidth interference of dual cards according to an embodiment of the present disclosure. If the terminal device is in a target scenario, at least one RRC network element is determined from the first RRC network element of the first user card and the second RRC network element of the second user card as the target RRC. The target scenario is that the terminal device switches from dual standby DSDS to dual communication DSDA, or the terminal device enters the DSDA scenario. Indication information is sent to the target RRC, and the indication information is used to instruct the target RRC to report the interference bandwidth of the target user card to the base station, where the target user card is determined based on the target RRC. Thus, when the terminal device processes the target scenario, the present disclosure can eliminate the bandwidth interference of the dual cards through the indication information, achieve concurrent processing of dual-card services, ensure the stability and reliability during the service processing, and improve the user experience.

[0054] Figure 2FIG. 0 is a schematic flowchart of a method for eliminating bandwidth interference of a dual SIM card according to an embodiment of the present disclosure. On the basis of the above embodiment, further combined with Figure 2 , the specific process of the method for eliminating bandwidth interference of the dual SIM card is explained, including the following steps:

[0055] S201. Receive a first resource application request sent by a first RRC network element. If there is no bandwidth interference on the first user SIM card, send a first resource application success message to the first RRC network element.

[0056] In an embodiment of the present disclosure, an Access Stratum Control (ASC) module in a terminal device UE can receive a first resource application request sent by the first RRC network element. Correspondingly, the ASC module can perform bandwidth interference determination. When there is no bandwidth interference on the first user SIM card, send a first resource application success message to the first RRC network element.

[0057] It should be noted that after sending the first resource application success message to the first RRC network element, the first user SIM card can continue to perform services, such as data services, voice services, etc.

[0058] S202. Receive a second resource application request sent by a second RRC network element. If there is bandwidth interference on the second user SIM card, determine that the terminal device is in a target scenario of switching from DSDS to DSDA.

[0059] In an embodiment of the present disclosure, the ASC module can receive a second resource application request sent by the second RRC network element. Correspondingly, the ASC module can perform bandwidth interference determination. When there is bandwidth interference on the second user SIM card, determine that the terminal device is in a target scenario of switching from DSDS to DSDA.

[0060] S203. If the terminal device is in the target scenario, determine at least one RRC network element from the first RRC network element of the first user SIM card and the second RRC network element of the second user SIM card as the target RRC.

[0061] In an embodiment of the present disclosure, when it is determined that the terminal device is in a target scenario of switching from DSDS to DSDA, the first RRC network element of the first user SIM card is used as the target RRC.

[0062] S204. Send an indication message to the target RRC. The indication message is used to instruct the target RRC to report the interference bandwidth of the target user SIM card to the base station, where the target user SIM card is determined based on the target RRC.

[0063] It should be noted that the target RRC is the first RRC network element, the target user card is the second user card, and the ASC module sends indication information to the first RRC network element, that is, sends an interference fallback request message to the first RRC network element. The interference fallback request message includes the interference bandwidth of the second user card. Accordingly, the first RRC network element can switch from the current cell to a target cell outside the interference bandwidth. The ASC module receives the interference fallback success message sent by the first RRC network element and sends a second resource application success message to the second RRC network element, so that the second RRC network element can execute services, realizing the concurrent execution of services for the dual cards.

[0064] It should be noted that the second RRC network element can execute various types of services, such as voice services, data services, etc., realizing the concurrent execution of services for the first user card and the second user card.

[0065] Figure 3 It is a schematic flowchart of a method for eliminating bandwidth interference of dual cards according to an embodiment of the present disclosure. On the basis of the above embodiment, further combined with Figure 3 , the specific process of the method for eliminating bandwidth interference of dual cards is explained, including the following steps:

[0066] S301, receive the first resource application request sent by the first RRC network element. If there is no bandwidth interference for the first user card, send a first resource application success message to the first RRC network element.

[0067] In the embodiment of the present disclosure, the ASC module can receive the first resource application request sent by the first RRC network element. Accordingly, the ASC module can perform bandwidth interference determination. When there is no bandwidth interference for the first user card, send a first resource application success message to the first RRC network element.

[0068] It should be noted that after sending the first resource application success message to the first RRC network element, the first RRC network element can execute services, such as data services, voice services, etc.

[0069] S302, receive the second resource application request sent by the second RRC network element. If there is no bandwidth interference for the second user card, send a second resource application success message to the second RRC network element.

[0070] In the embodiment of the present disclosure, the ASC module can receive the second resource application request sent by the second RRC network element. Accordingly, the ASC module can perform bandwidth interference determination. When there is no bandwidth interference for the second user card, send a second resource application success message to the second RRC network element.

[0071] S303, determine that the terminal device is in the target scenario where the terminal device enters DSDA.

[0072] It should be noted that when it is determined that the terminal device is in the target scenario for entering DSDA, that is, the dual-SIM dual-standby scenario, the services of the first user SIM card and the second user SIM card of the terminal device can be carried out concurrently. To prevent bandwidth interference between the two SIM cards during subsequent concurrent services, bandwidth interference cancellation for the two SIM cards can be performed in advance.

[0073] S304, if the terminal device is in the target scenario, determine at least one RRC network element from the first radio resource control (RRC) network element of the first user SIM card and the second RRC network element of the second user SIM card as the target RRC.

[0074] In the embodiments of the present disclosure, if the terminal device is in the target scenario for entering DSDA, the target RRC network element includes the first RRC network element and the second RRC network element.

[0075] S305, send indication information to the target RRC, where the indication information is used to instruct the target RRC to report the interference bandwidth of the target user SIM card to the base station, and the target user SIM card is determined based on the target RRC.

[0076] Wherein, the target user SIM card corresponding to the first RRC network element is the second user SIM card, and the target user SIM card corresponding to the second RRC network element is the first user SIM card.

[0077] It should be noted that the target RRC includes the first RRC network element and the second RRC network element. The target user SIM card corresponding to the first RRC network element is the second user SIM card, and the target user SIM card corresponding to the second RRC network element is the first user SIM card. The ASC module sends indication information to the first RRC network element, that is, sends the first notification message for entering the dual-SIM dual-standby (DSDA) mode to the first RRC network element, where the first notification message includes the interference bandwidth of the second user SIM card. The ASC module sends indication information to the second RRC network element, that is, sends the second notification message for entering the DSDA mode to the second RRC network element, where the second notification message includes the interference bandwidth of the first user SIM card. Correspondingly, the first RRC network element can switch from the current cell to a target cell outside the interference bandwidth of the second user SIM card, and the second RRC network element can switch from the current cell to a target cell outside the interference bandwidth of the first user SIM card, so that the first RRC network element and the second RRC network element can perform services in parallel.

[0078] Figure 4 It is a schematic flow diagram of a method for eliminating bandwidth interference between two SIM cards provided by the embodiments of the present disclosure.

[0079] As Figure 4 shown, the method for eliminating bandwidth interference between two SIM cards, which is executed by the target RRC, includes the following steps:

[0080] S401, receive the indication information sent by the terminal device.

[0081] In an embodiment of the present disclosure, the ASC module in the terminal device UE may send indication information to the target RRC. Correspondingly, the target RRC may receive the indication information sent by the ASC module.

[0082] S402. Report the interference bandwidth of the target user card to the base station according to the indication information, where the target user card is determined based on the target RRC.

[0083] For example, if the terminal device is in a target scenario of switching from DSDS to DSDA, the target RRC is the first RRC network element of the first user card, the first RRC corresponds to the first user card, the target user card is the second user card, the ASC module sends indication information to the first RRC network element, and according to the indication information, reports the interference bandwidth of the target user card to the base station, that is, reports the interference bandwidth of the second user card to the base station. After receiving the interference bandwidth of the second user card, the first RRC network element may switch from the current cell to a target cell outside the interference bandwidth.

[0084] For example, if the terminal device is in a target scenario of entering DSDA, and if the target RRC network elements include the first RRC network element and the second RRC network element, then the target user card corresponding to the first RRC network element is the second user card, and the target user card corresponding to the second RRC network element is the first user card. According to the indication information, report the interference bandwidth of the target user card (including the interference bandwidth of the second user card and the interference bandwidth of the first user card) to the base station. After receiving the interference bandwidth of the second user card, the first RRC network element, and after receiving the interference bandwidth of the first user card, the second RRC network element, the first RRC network element switches from the current cell to a target cell outside the interference bandwidth of the second user card, and the second RRC network element switches from the current cell to a target cell outside the interference bandwidth of the first user card. Then, the first RRC network element and the second RRC network element can continue to execute services, realizing the concurrent execution of services for dual cards.

[0085] According to a method for eliminating bandwidth interference of dual cards in an embodiment of the present disclosure, by receiving the indication information sent by the terminal device and reporting the interference bandwidth of the target user card to the base station according to the indication information, where the target user card is determined based on the target RRC, the target RRC network element may, based on the interference bandwidth of the target user card, switch the current cell of the target user card to a target cell outside the interference bandwidth. Thus, in the present disclosure, through the indication information, the current cell of the target user card can be switched to a target cell outside the interference bandwidth, eliminating the bandwidth interference of dual cards, realizing the concurrent processing of dual-card services, ensuring the stability and reliability in the service processing process, and improving the user experience.

[0086] Figure 5It is a schematic flowchart of a bandwidth interference cancellation method for a dual SIM card according to an embodiment of the present disclosure. Based on the above embodiment, further combined with Figure 5 , the specific process of the bandwidth interference cancellation method for the dual SIM card is explained as follows:

[0087] S501, send a first resource application request to the terminal device.

[0088] In the embodiment of the present disclosure, the target RRC is the first RRC of the first user SIM card, the first RRC corresponds to the first user SIM card, the target user SIM card is the second user SIM card, and a first resource application request is sent to the ASC module in the terminal device based on the first RRC.

[0089] S502, receive the first resource application success message sent by the terminal device when it determines that there is no bandwidth interference on the first user SIM card, and execute the service of the first user SIM card.

[0090] It should be noted that for the first resource application request sent by the first RRC network element to the ASC module, the ASC module can perform bandwidth interference determination. When there is no bandwidth interference on the first user SIM card, it receives the first resource application success message sent by the ASC module and executes the service of the first user SIM card.

[0091] S503, receive the indication information sent by the terminal device.

[0092] In the embodiment of the present disclosure, the first RRC receives the indication information sent by the ASC module, that is, the interference fallback request message, and the interference fallback request message includes the interference bandwidth of the second user SIM card.

[0093] S504, report the interference bandwidth of the target user SIM card to the base station according to the indication information, where the target user SIM card is determined based on the target RRC.

[0094] In the embodiment of the present disclosure, after receiving the indication information, it can report the interference bandwidth of the target user SIM card to the base station, that is, the interference bandwidth of the second user SIM card.

[0095] S505, receive the RRC reconfiguration message sent by the base station, and based on the RRC reconfiguration message, switch the first user SIM card from the current cell to the target cell outside the interference bandwidth.

[0096] S506, send a reconfiguration completion message corresponding to the RRC reconfiguration message to the base station.

[0097] It should be noted that after sending the reconfiguration completion message corresponding to the RRC reconfiguration message to the base station, the second user SIM card can execute the service, realizing the parallel execution of services by the first user SIM card and the second user SIM card.

[0098] Figure 6It is a schematic flowchart of a method for eliminating bandwidth interference of a dual SIM card according to an embodiment of the present disclosure. On the basis of the above embodiment, further combined with Figure 6 , the specific process of the method for eliminating bandwidth interference of a dual SIM card is explained, including the following steps:

[0099] S601, the target RRC network element is the first RRC network element, sends a first resource application request to the terminal device, receives the first resource application success message sent by the terminal device when it determines that there is no bandwidth interference on the first user card, and executes the service of the first user card.

[0100] S602, the target RRC network element is the second RRC network element, sends a second resource application request to the terminal device, receives the second resource application success message sent by the terminal device when it determines that there is no bandwidth interference on the second user card, and executes the service of the second user card.

[0101] S603, receive the indication information sent by the terminal device.

[0102] In the embodiment of the present disclosure, the target RRC network element includes the first RRC network element and the second RRC network element. The first RRC network element receives the first notification message for entering the DSDA mode sent by the terminal device, and the interference bandwidth of the second user card is included in the first notification message. The second RRC network element receives the second notification message for entering the DSDA mode sent by the terminal device, and the interference bandwidth of the first user card is included in the second notification message.

[0103] S604, according to the indication information, report the interference bandwidth of the target user card to the base station, where the target user card is determined based on the target RRC.

[0104] S605, the target RRC network element is the first RRC network element, receives the RRC reconfiguration message sent by the base station, and based on the RRC reconfiguration message, switches the first user card from the current cell to the target cell outside the interference bandwidth of the second user card.

[0105] It should be noted that after switching the first user card from the current cell to the target cell outside the interference bandwidth of the second user card, the target cell within the interference bandwidth of the second user card is actively avoided.

[0106] S606, the target RRC network element is the second RRC network element, receives the RRC reconfiguration message sent by the base station, and based on the RRC reconfiguration message, switches the second user card from the current cell to the target cell outside the interference bandwidth of the first user card.

[0107] It should be noted that after switching the second user card from the current cell to the target cell outside the interference bandwidth of the first user card, the target cell within the interference bandwidth of the first user card is actively avoided.

[0108] The specific process of the bandwidth interference cancellation method for dual cards proposed in the present disclosure will be explained below.

[0109] For example, as Figure 7 shown, the first RRC network element (NRRC) of the first user card sends a first resource application request "NRRC_ASC_TASK_APPLY_REQ" to the ASC module in the terminal device. The ASC module performs interference determination. If it is determined that there is no bandwidth interference for the first user card, the ASC module sends a first resource application success message "AS C_NRRC_TASK_APPLY_CNF" to the NRRC. The NRRC1 network element starts to execute services. The second RRC network element (XRRC) of the second user card sends a second resource application request "XRRC_ASC_TASK_APPLY_REQ" to the ASC module. The ASC module performs interference determination. If there is bandwidth interference for the second user card, the ASC module sends an interference fallback request message "ASC_NRRC_BAND_INTERFERENCE_FALLBACK_REQ" to the NRRC network element. Among them, the interference bandwidth (interference bandwidth list) of the second user card is carried in the interference fallback request message. After the NRRC network element receives the interference fallback request message sent by the ASC module, it determines the configuration assistance information (new interference list) of the terminal device UE and reports the configuration assistance information to the base station "UE AssistanceInformation", that is, reports the interference bandwidth of the second user card to the base station. The base station sends an RRC reconfiguration message "RRC Reconfiguration" to the NRRC network element. The NRRC network element receives the reconfiguration message sent by the base station and switches the first user card from the current cell to a target cell outside the interference bandwidth based on the RRC reconfiguration message. The reconfiguration message carries withsync. After switching the first user card from the current cell to a target cell outside the interference bandwidth, the NRRC network element sends a reconfiguration completion message "RRC Re configuration Complete" corresponding to the RRC reconfiguration message to the base station, and sends an interference fallback success message "NRRC_ASC_BAND_INTERFERENCE_FALLBACK_CNF" to the ASC module. The ASC module sends a second resource application success message "ASC_XRRC_TASK_APPLY_CNF" to the second network element XRR C, and then the second network element XRRC starts to execute services, realizing the concurrent execution of dual-card services.

[0110] For example, as Figure 8As shown in the figure, if the terminal device is in the target scenario of entering DSDA, the first RRC network element (NRRC) of the first user card sends a first resource application request "NRRC_ASC_TASK_APPLY_REQ" to the ASC module in the terminal device. The ASC module performs interference judgment. If it is judged that there is no bandwidth interference for the first user card, the ASC module sends a first resource application success message "ASC_NRRC_TASK_APPLY_CNF" to the NRRC, and the NRRC network element starts to execute services. The second RRC network element (XRRC) of the second user card sends a second resource application request "XRRC_ASC_TASK_APPLY_REQ" to the ASC module, and the ASC module performs interference judgment. If there is no bandwidth interference for the second user card, the ASC module sends a second resource application success message "ASC_XRRC_TASK_APPLY_CNF" to the XRRC network element, and the XRRC network element starts to execute services. When dual-card services are concurrent, the mode is switched from DSDS to DSDA. The ASC module sends a first notification message "ASC_NRRC_ENTRY_DSDA_IND" indicating entry into the dual-standby DSDA mode to the NRRC network element, where the first notification message includes the interference bandwidth of the second user card, and sends a second notification message "ASC_XRRC_ENTRY_DSDA_IND" indicating entry into the dual-standby DSDA mode to the XRRC network element, where the second notification message includes the interference bandwidth of the first user card. The NRRC network element reports the interference bandwidth of the second user card, i.e., the configuration assistance information "UE Assistance Information", to the base station, and the XRRC network element reports the interference bandwidth of the first user card, i.e., the configuration assistance information "UE Assistance Information", to the base station. Furthermore, based on information such as the location movement of the terminal device, the first user card can be preferentially switched from the current cell to a target cell outside the interference bandwidth of the second user card, and the second user card can be preferentially switched from the current cell to a target cell outside the interference bandwidth of the first user card. The base station sends an RRC reconfiguration message "RRC Reconfiguration" to the NRRC network element. The NRRC network element receives the reconfiguration message and switches the first user card from the current cell to a target cell outside the interference bandwidth of the second user card based on the RRC reconfiguration message. The base station sends an RRC reconfiguration message "RRC Reconfiguration" to the XRRC network element. The XRRC network element receives the reconfiguration message and switches the second user card from the current cell to a target cell outside the interference bandwidth of the first user card, realizing the concurrent execution of dual-card services.

[0111] In summary, according to a method for eliminating bandwidth interference of dual SIM cards according to an embodiment of the present disclosure, when services are concurrently processed by a first user SIM card and a second user SIM card, the bandwidth of the serving cell (primary cell or secondary cell) of the first user SIM card interferes with the bandwidth of the serving cell (primary cell or secondary cell) of the second user SIM card, resulting in the inability to concurrently process services of the first user SIM card and the second user SIM card. According to the present disclosure, based on the target scenario in which the terminal device is located and the interference bandwidth in the indication information, the first user SIM card can be switched from the current cell to a target cell outside the interference bandwidth or from the current cell to a target cell outside the interference bandwidth of the second user SIM card, and the second user SIM card can be switched from the current cell to a target cell outside the interference bandwidth of the first user SIM card, thereby eliminating the bandwidth interference of the dual SIM cards, realizing concurrent processing of dual SIM card services, ensuring the stability and reliability during the service processing, and improving the user experience.
