[0020] The technical solutions 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 only part of the embodiments of the present application, rather than all of the embodiments.

[0021] Communication system architecture

[0022] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: global system of mobile communication (GSM) system, code division multiple access (CDMA) system, wideband code division multiple access (WCDMA) system, general packet radio service (GPRS), long term evolution (LTE) system, advanced long term evolution (LTE-A) system, new radio (NR) system, evolution system of NR system, LTE-based access to unlicensed spectrum (LTE-U) system, NR-based access to unlicensed spectrum (NR-U) system, non terrestrial network (NTN) system, universal mobile telecommunication system (UMTS), wireless local area networks (WLAN), wireless fidelity (WLAN-based access to unlicensed spectrum, NR-U) system, non terrestrial network (NTN) system, universal mobile telecommunication system (UMTS), wireless local area networks (WLAN), wireless Fidelity (WLAN-based access to unlicensed spectrum, NR-U) system, etc. fidelity, WiFi), fifth-generation communication (5G) systems or other communication systems, such as future communication systems, such as sixth-generation mobile communication systems, and satellite communication systems.

[0023] The communication system in the embodiment of the present application can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, or a standalone (SA) networking scenario.

[0024] The communication system in the embodiment of the present application can be applied to an unlicensed spectrum, where the unlicensed spectrum can also be considered as a shared spectrum; or, the communication system in the embodiment of the present application can also be applied to an authorized spectrum, where the authorized spectrum can also be considered as a dedicated spectrum.

[0025] The embodiments of the present application can be applied to NTN systems and terrestrial networks (TN) systems. As an example but not a limitation, NTN systems include NR-based NTN systems and IoT-based NTN systems.

[0026] For example, Figure 1 The following is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. Figure 1 As shown, the communication system 100 may include a terminal device 110 and a network device 120 .

[0027] The terminal device 110 may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device, etc.

[0028] In the embodiment of the present application, the terminal device 110 may include multiple SIM cards for communication, and therefore, the terminal device 110 may also be referred to as a multi-card terminal device or a multi-card multi-standby terminal device.

[0029] The embodiment of the present application does not specifically limit the type of the terminal device 110. For example, the terminal device 110 may be a station (STATION, ST) in a WLAN, a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a next-generation communication system such as an NR network, or a terminal device in a future-evolved public land mobile network (PLMN) network, etc.

[0030] The network device 120 may refer to a radio access network (RAN) node (or device) that accesses the terminal device 110 to a wireless network, and may provide a network for the terminal device 120. For example, the network device 120 may be a base station. The base station can broadly cover various names as follows, or be replaced with the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmission point (TRP), transmission point (TP), master station MeNB, secondary station SeNB, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, base band unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. The base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof. A base station may also refer to a communication module, modem or chip used to be set in the aforementioned device or apparatus. A base station may also be a mobile switching center, a device that performs base station functions in device-to-device D2D, vehicle-to-everything (V2X), machine-to-machine (M2M) communications, a network-side device in a 6G network, or a device that performs base station functions in future communication systems. A base station may support networks with the same or different access technologies.

[0031] In the embodiment of the present application, the network device 120 can provide services for the cell, and the terminal device 110 communicates with the network device 120 by accessing the cell using transmission resources (e.g., frequency domain resources, or spectrum resources). The cell can be a cell corresponding to the network device 120 (e.g., a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cell here can include: a metro cell, a micro cell, a pico cell, a femto cell, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0032] Figure 1 A network device 120 and two terminal devices 110 are shown by way of example. In some embodiments of the present application, the communication system 100 may include multiple network devices 120 and each network device 120 may include another number of terminal devices 110 within its coverage area, which is not limited in the embodiments of the present application.

[0033] As mentioned above, the multi-card multi-standby terminal device may include a first user identification card and a second user identification card. The first user identification card and the second user identification card may access the same or different service cells, so that the first user identification card and the second user identification card are in standby mode at the same time. In this way, the user can make or receive calls or send and receive text messages at will without switching networks.

[0034] SIM card is a user identification card used to uniquely identify mobile users in wireless communication systems. SIM card stores user data, authentication methods and keys, which can be used by the communication network to identify the user's identity. At the same time, users use SIM card to complete the connection with the communication system and exchange information. Terminal devices need to be equipped with SIM card to be recognized by the network, and then complete network registration and realize wireless communication.

[0035] It should be noted that in Figure 2-Figure 6 In order to simplify the diagram, the first user identification card is marked as SIM card 1 and the second user identification card is marked as SIM card 2.

[0036] For multi-SIM multi-standby terminal devices, due to the limited radio frequency resources of the terminal devices, they generally can only support single-transmission and single-reception or single-transmission and multiple-reception, but not pure multiple-transmission and multiple-reception. In other words, multi-SIM multi-standby terminal devices cannot use multiple SIM cards to simultaneously perform uplink and downlink data services on multiple networks that correspond to multiple SIM cards one by one. Therefore, multi-SIM multi-standby terminal devices can only execute services on one SIM card at a time.

[0037] In some scenarios, the first user identification card needs to seize the radio frequency resources of the terminal device used by the second user identification card to execute the related services of the first user identification card. After the related services of the first user identification card are executed, the radio frequency resources will be released so that the second user identification card can continue to access the wireless network, thereby realizing the recovery of the wireless communication of the second user identification card.

[0038] For example, Figure 2 As shown, the scenario may be that the second user identification card responds to the request of the second service and uses radio frequency resources to communicate with the network device so that the second user identification card enters the connection state, and the second user identification card starts to execute the second service after entering the connection state. In the process of executing the second service, the terminal device receives the first service request of the first user identification card. If the priority of the first service is higher than that of the second service, the terminal device will cause the first user identification card to seize the radio frequency resources so that the first user identification card enters the connection state, so that the first service (for example, the first service is a call service and the second service is a game service) can be processed preferentially. After the first service of the first user identification card is completed, the radio frequency resources will be released so that the second user identification card can resume network connection.

[0039] Or, this scene can also be, the second subscriber identification card is main card, and the first subscriber identification card is secondary card.Main card can be understood as tacit network connection card.When the second subscriber identification card is in non-business state (for example, non-business state can be idle state (IDLE) or inactive state (inactive)), the second subscriber identification card also needs to use radio frequency resources, so as to resident on the best community and ensure the high efficiency of the second subscriber identification card accessing the wireless network.If the first subscriber identification card needs to process the business of the first subscriber identification card at this moment, the first subscriber identification card still can seize the radio frequency resources used by the second subscriber identification card, to process the business of the first subscriber identification card.After the business execution of the first subscriber identification card ends, radio frequency resources will be released so that the second subscriber identification card can recover network connection.

[0040] It should be noted that, when the second user identification card is executing the second service or is in a non-service state, it can also perform cell measurement based on the measurement configuration message sent by the network device to ensure the quality of the accessed network. Among them, the measurement configuration message includes a measurement cell set (or measurement target list) of the second user identification card. The measurement cell set of the second user identification card may include the identifier of the serving cell of the second user identification card and the identifier of the neighboring cell of the serving cell. In some embodiments, the neighboring cell of the serving cell can be referred to as a neighboring cell. It should be noted that when the first user identification card seizes the radio frequency resources, the second user identification card cannot implement the above-mentioned cell measurement.

[0041] Combine the following Figure 3 The following is an exemplary description of possible implementations of restoring the network connection by the second subscriber identification card.

[0042] like Figure 3 As shown, the process of restoring the network connection of the second user identification card is as follows:

[0043] In step S310, a first service termination indication message of a first subscriber identity card is received.

[0044] In step S320, the second subscriber identity card determines a next service recovery action.

[0045] like Figure 3 As shown, the next service recovery action may include any of the following actions: Action 1, attempt to directly restore the original wireless transmission link on the original service cell; Action 2, attempt to search and reside in the cell, and perform connection reconstruction; Action 3, attempt to return to the idle state (IDLE) and search and reside in the cell. The original wireless transmission link can be understood as the uplink and downlink transmission link established by the second user identification card using radio frequency resources for wireless communication with the network device before the first service is executed.

[0046] The present application embodiment does not specifically limit the judgment criteria of the second user identification card, and can be set as needed. For example, the second user identification card can judge the next service recovery action according to the execution time of the first service.

[0047] In step S330, according to the determination result of step S320, action 1, action 2 or action 3 is executed.

[0048] However, through Figure 3 The method shown is that the second user identification card takes a long time to search the current service cell or establish a wireless transmission link. Figure 3 The method shown causes the second user identification card to take a long time to access the wireless network, resulting in a poor user experience.

[0049] The reason is that in step S330, no matter which of the above-mentioned actions 1, 2 and 3 is performed by the second user identification card, the second user identification card is performed based on the measurement cell set of the second user identification card. Specifically, action 1 is to try to restore the original wireless transmission link before being seized on the service cell in the measurement cell set of the second user identification card. The cell search and residence in actions 2 and 3 are to perform network search and residence reconstruction within the range of the measurement cell set including the second user identification card.

[0050] However, the measurement cell set of the second user identification card is obtained before the first user identification card performs the first business. As the first user identification card seizes the radio frequency resources to perform the first business to the end of the first business, the terminal equipment is likely to move. Therefore, the wireless environment around the terminal equipment also changes accordingly. At this time, the signal of the serving cell and / or the adjacent cell in the measurement cell set of the second user identification card may deteriorate. Therefore, when the second user identification card does not perceive this change, still performing the above-mentioned action 1, action 2 or action 3 based on the measurement cell set of the second user identification card may increase the time consuming of the second user identification card accessing the wireless network, resulting in poor user experience.

[0051] It should be noted that, for the sake of distinction and understanding, the serving cell and the neighboring cell in the measurement cell set of the second SIM card before the radio frequency resources are preempted are referred to as the original serving cell and the neighboring cell of the original serving cell respectively.

[0052] For example, when the second user identification card performs action 1, the signal of the original service cell may deteriorate, and the signal may be so poor that the original uplink and downlink transmission links cannot be restored normally. Then, since the terminal device does not perceive this, it will execute according to the normal process of restoring the original uplink and downlink transmission links. When the execution is unsuccessful, the indication of Radio Link Failure (RLF) will be triggered. Specifically, the operation of the terminal device is as follows: N310 out of sync->start T310->T310 timeout->trigger RLF. Further, after triggering RLF, the terminal device attempts to perform a cell search for the second user identification card to find a suitable cell to reside in. As a result, the second user identification card spends a long time to connect to the network, which leads to a longer interval for the subsequent recovery of the service.

[0053] For another example, when the second user identification card performs action 2 or action 3, the signal of the original service cell or the neighboring cell of the original service cell deteriorates, so the second user identification card does not need to search for the network and reside in the measurement cell set of the second user identification card. However, since the terminal device does not perceive this, it will first search for the network in the measurement cell set of the second user identification card according to normal steps, which also causes the second user identification card to spend a long time to connect to the network, thereby increasing the interval for subsequent service recovery.

[0054] In summary, in the related art, the network connection method for the second user identification card after the first service of the first user identification card is completed takes a long time, resulting in a poor user experience.

[0055] In view of this, an embodiment of the present application proposes a communication method, which can use the first user identification card to continue to perform cell measurement (i.e., the first measurement) for the second user identification card and generate a measurement report when the first user identification card seizes the radio frequency resources used by the second user identification card. In addition, after the first service of the first user identification card is executed, the current service cell of the second user identification card can be determined according to the first measurement report. This method can sense the changes in the signals of each cell in the measurement cell set of the second user identification card before establishing the second user identification card to access the network, can avoid the time consumption increased by the invalid network search action, effectively improve the network connection efficiency of the second user identification card after the first service of the first user identification card is executed, thereby effectively ensuring the user experience.

[0056] Combine the following Figure 4 The communication method in the embodiment of the present application is described in detail. The method is applied to the terminal device mentioned above, and the terminal device includes a first user identification card and a second user identification card.

[0057] See Figure 4 , the method includes steps S410 to S450.

[0058] In step S410, a request for a first service from a first subscriber identification card is received.

[0059] The request for the first service may include specific content of the first service and the priority of the first service. The terminal device may determine whether the first service of the first subscriber identity card needs to occupy the radio frequency resources of the terminal device according to the request for the first service.

[0060] In the embodiment of the present application, the first service occupying the radio frequency resources of the terminal device can be understood as that before the first service of the first user identification card occupies the radio frequency resources, the second user identification card is using the radio frequency resources. After the first service occupying the radio frequency resources of the terminal device, the second user identification card will be unable to communicate with the network device.

[0061] As described above, when the second SIM card uses radio frequency resources, it can perform cell measurement on its measurement cell set and generate a measurement report. However, after the first service seizes the radio frequency resources, the second SIM card cannot continue to perform cell measurement.

[0062] The present embodiment does not specifically limit the criteria for determining whether to seize radio frequency resources. For example, it can be determined whether the first service of the first SIM card needs to seize radio frequency resources of the terminal device according to the priority of the first service and / or the status of the second SIM card.

[0063] As a way to achieve this, Figure 2As shown, when the state of the RRC connection of the second user identification card is the connected state, it can be determined whether the first service of the first user identification card needs to seize the radio frequency resources of the terminal device according to whether the priority of the first service is higher than the priority of the second service. Specifically, if the priority of the first service is higher than the priority of the second service, it is necessary to seize the radio frequency resources. If the priority of the first service is lower than the priority of the second service, it is not necessary to seize the radio frequency resources, that is, the first service is not processed temporarily.

[0064] When the RRC connection state of the second user identification card is connected, the second user identification card keeps occupying the radio frequency resources of the terminal device to establish the original wireless transmission link of the second user identification card for executing the second service. The original wireless transmission link is used to connect the second user identification card and the original serving cell.

[0065] In some embodiments, the original wireless transmission link of the second user identification card is also used for the second user identification card to receive a measurement configuration message or a system information block (SIB) from the network device.

[0066] As another implementation manner, if the state of the RRC connection of the second subscriber identity card is an idle state or an inactive state, it is determined that the first service of the first subscriber identity card needs to occupy radio frequency resources.

[0067] In step S420, in response to the first subscriber identification card needing to seize the radio frequency resources of the terminal device used by the second subscriber identification card, the measurement cell set of the second subscriber identification card is sent to the first subscriber identification card.

[0068] The measurement cell set of the second user identification card includes the original service cell of the second user identification card and the neighboring area of ​​the original service cell. Wherein, the neighboring area of ​​the original service cell may include multiple ones. The embodiment of the present application does not specifically limit the source of the measurement cell set of the second user identification card. As an implementation method, the measurement cell set of the second user identification card may be included in the measurement configuration message or system message received by the second user identification card.

[0069] In step S430, a first measurement is performed using a first subscriber identification card, and a first measurement report is generated.

[0070] The first measurement includes measurement performed by the first subscriber identity card based on the measurement cell set of the second subscriber identity card. The first measurement can be understood as the cell measurement of the second subscriber identity card performed by the first subscriber identity card.

[0071] The first measurement report may refer to a measurement report generated after performing measurement evaluation on each cell in the measurement cell set of the second subscriber identity card. The first measurement report is used to indicate the network environment of the second subscriber identity card.

[0072] In some embodiments, the first measurement report may include the signal quality of the original serving cell in the measurement cell set of the second subscriber identity card. Optionally, the first measurement report may also include the signal quality of the neighboring cell of the original serving cell in the measurement cell set of the second subscriber identity card.

[0073] Signal quality includes but is not limited to at least one of the following: Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Noise ratio (SNR), and S parameters used for cell selection.

[0074] In step S440, in response to the end of the first service, a first measurement report is sent to the second subscriber identity card.

[0075] In the embodiment of the present application, the sending of the first measurement report and the measurement cell set of the second user identification card may be performed through a software interface inside the terminal device.

[0076] In step S450, the current serving cell of the second subscriber identity card is determined according to the first measurement report.

[0077] The current serving cell of the second SIM card can be understood as the cell where the second SIM card resides after reclaiming the radio frequency resources. In the embodiment of the present application, the first measurement report can be used to auxiliary determine the current serving cell of the second SIM card, so as to improve the speed of searching and residing in the network.

[0078] As an example, the first measurement report includes the signal quality of the original service cell of the second user identification card. According to the first measurement report, determining the current service cell of the second user identification card includes: according to the first measurement report, determining whether the signal quality of the original service cell of the second user identification card meets the preset condition (for example, whether RSRP is greater than a set threshold value, or whether the S parameter is greater than 0); in response to the signal quality of the original service cell of the second user identification card meeting the preset condition, determining the original service cell as the current service cell of the second user identification card; in response to the signal quality of the original service cell of the second user identification card not meeting the preset condition, determining the current service cell of the second user identification card in other cells except the original service cell.

[0079] By preferentially confirming whether the original service cell can be used as the current service cell, in the scenario where the second user identification card can try to restore the original wireless transmission link, it can avoid the invalid restoration of the original wireless transmission link due to the poor quality of the original service cell and can choose to enter the network search and stay. At the same time, it can also avoid searching for the original service cell again in the network search and stay scenario. Therefore, it can effectively reduce the networking time of the second user identification card.

[0080] The embodiment of the present application does not specifically limit the method of determining the current serving cell of the second SIM card in cells other than the original serving cell. As an implementation method, the second SIM card can search multiple cells other than the original serving cell to find the cell with the best network quality as the current serving cell.

[0081] However, since there are many cells other than the original serving cell, the time consumption of the second subscriber identity card to connect to the network may be increased when searching for a network and residing thereon.

[0082] In order to reduce the networking time of the second user identification card, the first measurement report also includes the signal quality of the neighboring area of ​​the original service cell of the second user identification card. Based on this, determining the current service cell of the second user identification card in other cells except the original service cell may include: determining whether the signal quality of the neighboring area of ​​the original service cell meets the preset conditions; in response to the signal quality of the neighboring area of ​​the original service cell meeting the preset conditions, determining the current service cell of the second user identification card in the neighboring area of ​​the original service cell; in response to the signal quality of the neighboring area of ​​the original service cell not meeting the preset conditions, searching other cells except the original service cell and the neighboring area of ​​the original service cell, and determining the current service cell of the second user identification card in other cells except the original service cell and the neighboring area of ​​the original service cell.

[0083] Before searching for network and residing, the current service cell of the second user identification card can be determined by the signal quality of the neighboring cells of the original service cell of the second user identification card in the measurement report to avoid network searching or avoid searching for network in cells with poor signals. Specifically, if the measurement report indicates that there are cells whose signal quality meets the preset conditions in the neighboring cells of the original service cell, the cells that meet the preset conditions are sorted, and the cells that are ranked first or ranked first can be randomly selected for residing, so that re-searching for network and residing can be avoided, effectively reducing the networking time of the second user identification card. If the measurement report indicates that the signal quality of no cell in the neighboring cells of the original service cell meets the preset conditions, these cells can be avoided for network searching and residing, effectively reducing the number of network searches, thereby effectively reducing the networking time of the second user identification card.

[0084] The communication method in the embodiment of the present application can utilize the first user identification card to continue to perform cell measurement (i.e., the first measurement) and generate a measurement report for the second user identification card when the first user identification card seizes the radio frequency resources used by the second user identification card. And, after the first service execution of the first user identification card ends, the current serving cell of the second user identification card can be determined according to the first measurement report. This mode can sense the change of the signal of each cell in the measurement cell set of the second user identification card before the second user identification card accesses the network, can avoid the time consuming of invalid network search or reconstruction action increase, effectively improve the network connection efficiency of the second user identification card after the first service execution of the first user identification card ends, thereby effectively ensuring the user experience.

[0085] In some embodiments, Figure 5 As shown, the communication method in the embodiment of the present application may further include step S460.

[0086] In step S460, a wireless transmission link of the second subscriber identity card is established or restored according to the current serving cell of the second subscriber identity card.

[0087] The wireless transmission link of the second user identification card is used to connect the second user identification card and the network device corresponding to the current serving cell of the second user identification card. By establishing the wireless transmission link of the second user identification card, the second user identification card can access the network, thereby realizing the transmission of uplink and downlink data.

[0088] The wireless transmission link may include, for example, but is not limited to: Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), Physical Downlink Control Channel (PDCCH), and Physical Downlink Shared Channel (PDSCH).

[0089] As an example, establishing or restoring the wireless transmission link of the second user identification card based on the current service cell of the second user identification card includes: in response to the current service cell of the second user identification card being the original service cell and the execution duration of the first service being less than the target duration, restoring the original wireless transmission link established based on the original service cell to the wireless transmission link of the second user identification card.

[0090] As another implementation method, establishing or restoring the wireless transmission link of the second user identification card according to the current service cell of the second user identification card includes: in response to the current service cell of the second user identification card being the original service cell and the execution duration of the first service being greater than the target duration, initiating a connection request to the original service cell to re-establish the wireless transmission link of the second user identification card, and restoring the original wireless transmission link to the wireless transmission link of the second user identification card.

[0091] As another implementation, according to the current serving cell of the second user identification card, establishing or restoring the wireless transmission link of the second user identification card includes: in response to the current serving cell of the second user identification card not being the original serving cell, initiating a connection request to the current serving cell to reestablish the wireless transmission link of the second user identification card. In some embodiments, the second user identification card may also initiate a connection request to the current serving cell after returning to an idle state.

[0092] In the embodiment of the present application, the first SIM card seizes the radio frequency resources in order to execute the first service described above. Therefore, the first SIM card performing the first measurement using the first SIM card described above can be implemented in the process of the first SIM card executing the first service.

[0093] In view of this, the communication method in the embodiment of the present application may further include the step of executing the first service. The step of executing the first service may specifically include:

[0094] 1. Access the service cell using the radio frequency resources of the terminal device. After the terminal device accesses the service cell, a wireless transmission link can be established with the terminal device to execute the first service. After accessing the wireless network, the terminal device can also use the radio frequency resources to receive the measurement cell set of the first user identification card sent by the network device to which it is connected. The measurement cell set of the first user identification card can be included in the measurement configuration message sent by the network device.

[0095] 2. Perform a second measurement using the first subscriber identity card and generate a second measurement report. The second measurement includes measurements performed based on a measurement cell set of the first subscriber identity card, and the second measurement report is used to switch a serving cell of the first subscriber identity card.

[0096] The embodiment of the present application does not specifically limit the algorithm of the first measurement. As an implementation method, the measurement period of the first measurement can be greater than the measurement period of the second measurement, that is, compared with the second measurement, the first measurement is a low-density measurement. Low-density measurement can be understood as in the first measurement, the first user identification card can use low-density scheduling for scheduling the measurement target configured by the second user identification card (i.e., the measurement cell set of the second user identification card).

[0097] As another implementation, the measurement period of the first measurement may be less than or equal to the measurement period of the second measurement. When the measurement period of the first measurement is less than the measurement period of the second measurement, the first measurement is also referred to as a high-density measurement. By performing the first measurement in a high-density measurement manner, the accuracy of the first measurement can be ensured.

[0098] In some embodiments, the priority of the first measurement may be lower than the priority of the second measurement to prioritize the execution of the first service.

[0099] In some embodiments, the priority of the first measurement may be greater than or equal to the priority of the second measurement to ensure execution of the first measurement.

[0100] The embodiment of the present application does not specifically limit the Radio Access Technology (RAT) of the serving cells accessed by the first user identification card and the second user identification card.

[0101] For example, the wireless access standards of the service cells accessed by the first user identification card and the second user identification card may be the same. Exemplarily, the wireless access standards of the service cells accessed by the first user identification card and the second user identification card are both NR or LTE.

[0102] For another example, the wireless access standards in which the first user identification card and the second user identification card reside may be different. Exemplarily, the wireless access standard of the first user identification card and the accessed service cell is NR, and the wireless access standard of the service cell accessed by the second user identification card is LTE. Alternatively, the wireless access standard of the first user identification card and the accessed service cell is LTE, and the wireless access standard of the service cell accessed by the second user identification card is NR.

[0103] In view of this, in some embodiments, in response to the wireless access standard of the service cell accessed by the first user identification card being different from the wireless access standard of the original service cell accessed by the second user identification card, the first measurement is performed by using the first user identification card to perform inter-RAT measurement.

[0104] In order to facilitate the understanding of the embodiments of the present application, Figure 6 The communication method in the embodiment of the present application is used to exemplarily explain how to restore the network after the second service of the second user identification card in the dual-SIM dual-standby terminal device is interrupted.

[0105] See Figure 6 , the communication method includes steps S610-S660.

[0106] In step S610, the second subscriber identity card enters a connection state.

[0107] Specifically, the second subscriber identity card may communicate with the network device using radio frequency resources in response to the request of the second service, so that the second subscriber identity card enters a connected state.

[0108] In step S620, the second subscriber identification card executes the second service.

[0109] Wherein, step S620 may further include step S621: the second user identification card: receiving a measurement configuration message sent by the network device. The measurement configuration message is used to perform cell measurement, and the measurement configuration message includes a measurement cell set of the second user identification card.

[0110] In step S630, in response to the first subscriber identification card successfully seizing the radio frequency resources, the measurement cell set of the second subscriber identification card is sent to the first subscriber identification card.

[0111] The measurement cell set of the second subscriber identity card includes an original serving cell of the second subscriber identity card and a neighboring cell of the original serving cell.

[0112] Among them, step S630 may occur in the process of executing the second service. Specifically, the terminal device receives the first service request of the first user identification card, and if the priority of the first service is higher than the priority of the second service, the terminal device will make the first user identification card seize the radio frequency resources, interrupt the second service and make the first user identification card enter the connection state.

[0113] In step S640, the first subscriber identification card executes the first service.

[0114] The process of the first subscriber identification card executing the first service may further include the first measurement and the second measurement mentioned above, and generate a first measurement report and a second measurement report.

[0115] In step S650, in response to the first service being terminated, a first measurement report is sent to the second subscriber identity card.

[0116] In step S660, an attempt is made to restore the network connection for the second subscriber identity card according to the first measurement report.

[0117] Specific recovery strategies can be:

[0118] 1. If the original serving cell of the second SIM card is poor (for example, RSRP is less than the set threshold or S<0, etc.), then no attempt is made to restore the connection of the original serving cell in subsequent actions. For example, no attempt is made to restore the original wireless transmission link for uplink and downlink transmission on the original serving cell. Or the original serving cell is not attempted when searching for a network and staying.

[0119] 2. When trying to reside in other cells except the original serving cell, the first measurement report returned by the first user identification card can be referred to. If there are better cells in the first measurement report (RSRP is greater than the set threshold value or S>0), the cells are sorted and selected for residence. If there are no cells that can be resided in the first measurement report, the second user identification card avoids these frequency points / cells and searches for other cells.

[0120] The method in the embodiment of the present application can directly do the resident operation without spending a long time on the uplink and downlink recovery when the second user identification card recovers the network connection and finds that the signal quality of the original service cell has deteriorated; at the same time, the method can also use the first measurement report as a basis to select the best cell to reside in during the resident search phase of the second user identification card, avoiding the frequency point / cell with poor signal. Therefore, the time consumed by the second user identification card in recovering the network can be reduced, and the user experience is effectively improved.
