Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of communication technology, and in particular, to a control method for switching connection and an apparatus thereof. BACKGROUND

[0002] With the development of wireless communication technology, more and more terminal devices can support multi-card mode. For a terminal device supporting multi-card mode, it can have multiple different processing modes, such as dual-card single standby, dual-card dual standby dual access, and the like, and these processing modes are usually based on manufacturer implementation.

[0003] Generally, when the multi-card terminal device communicates with a first system, it may need to frequently listen to a second system for paging, measurement, reading of system messages, and the like. Thus, it can affect the performance of the first system. If the second system is not listened to for paging, measurement, reading of system messages, and the like, the terminal device can not be able to establish a service connection with the second system. In addition, when the multi-card terminal device receives a paging message of the second system, it also needs to determine whether to respond to the paging. If the multi-card terminal device does not respond to the paging message of the second system all the time, the second system will keep paging the terminal device until the maximum number of times is reached. This not only wastes signaling resources, but also can trigger a false operation of the second system.

[0004] Therefore, how to ensure the reliable use of the multi-card terminal device is very important. SUMMARY

[0095] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art can know that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0096] The control method of the switched connection and the device thereof provided by the present disclosure will be described in detail below in combination with the drawings.

[0097] Please refer to Figure 2 , Figure 2 is a flowchart of a control method of a switched connection provided by the embodiments of the present disclosure, and the method is executed by an access network device. As Figure 2 indicated, the method can include but is not limited to the following steps:

[0098] Step 21, sending first indication information to a terminal device, wherein the first indication information is used to indicate a switched connection configuration to the terminal device, and the terminal device includes at least two subscriber identity modules.

[0099] The switched connection configuration can be configuration information used to instruct the terminal device to disconnect the connection with the access network device.

[0100] In addition, the subscriber identity module (SIM) is also called a SIM card, or can also be a universal subscriber identity module (USIM), which can represent the identity information of the terminal device when communicating with different access network devices.

[0101] Generally, even if there are multiple SIM cards in the terminal device, the terminal device can only communicate with the access network device corresponding to one SIM card at a certain moment, and cannot simultaneously communicate with other access network devices corresponding to other SIM cards.

[0102] Correspondingly, when the terminal device communicates with the access network device corresponding to a certain SIM card, it may need to frequently listen to paging, measure, read system messages, etc. of other access network devices corresponding to other SIM cards. Thus, it may affect the performance of the currently communicating access network device. If no listening to paging, measuring, reading system messages, etc. of other access network devices are performed, the terminal device may not be able to establish a service connection with other access network devices, thereby not only causing waste of communication resources, but also possibly affecting the normal communication transmission.

[0103] In the embodiments of the present disclosure, for a terminal device with multiple SIM cards, the access network device can send first indication information indicating a switching connection configuration to the terminal device, so that the terminal device can learn the switching connection configuration according to the first indication information, and perform switching connection based on the switching connection configuration. Thus, it is ensured that the communication transmission of the current connection of the access network device is not affected, and the failure of other access network services is avoided, and the reliability of the multi-card terminal device is improved.

[0104] Optionally, the first indication information can indicate a time length during which the terminal device disconnects from the access network device.

[0105] For example, the first indication information sent by the access network device to the terminal device indicates that the terminal device can disconnect from the access network device for 3 milliseconds (ms). Thus, the terminal device can disconnect from the current access network device when there is a service demand, and the time length of disconnection is controlled within 3 ms.

[0106] Optionally, the first indication information can indicate a time pattern of disconnection of the terminal device from the access network device.

[0107] The time pattern can reflect the situation of disconnection of the terminal device from the access network device at different time periods or different time instants, which is not limited in the present disclosure.

[0108] For example, the protocol stipulates or the access network device configures that the terminal device can disconnect from the access network device according to the time pattern according to the demand at the time instant of receiving the first indication information, and the like, which is not limited in the present disclosure.

[0109] Optionally, the time pattern can include multiple time pairs.

[0110] Each time pair can include two time instants, and the two time instants can represent a disconnection time instant and a connection time instant of one disconnection and connection, respectively. For example, the disconnection time instant is t1, and the connection time instant is t2, and the time pair can be represented as (t1, t2), and the like, which is not limited in the present disclosure.

[0111] Optionally, the time interval between the disconnection time instant and the connection time instant in each time pair can be the same.

[0112] For example, the three time pairs in the time pattern can be represented as (t1, t1+T), (t2, t2+T), and (t3, t3+T) respectively, where the time interval between the disconnection time and the connection time in each time pair is T. Thus, when the terminal device has a service demand, the terminal device can disconnect the connection with the access network device at time t1, and reconnect with the access network device at time t1+T; or the terminal device can disconnect the connection with the access network device at time t2, and reconnect with the access network device at time t2+T; or the terminal device can disconnect the connection with the access network device at time t3, and reconnect with the access network device at time t3+T, and so on. The present disclosure does not limit this.

[0113] Optionally, the time interval between the disconnection time and the connection time in each time pair can also be different.

[0114] For example, the three time pairs in the time pattern can be represented as (t1, t1+2ms), (t2, t2+5ms), and (t3, t3+7ms) respectively. Thus, when the terminal device has a service demand, the terminal device can disconnect the connection with the access network device at time t1, and reconnect with the access network device at time t1+2ms; or the terminal device can disconnect the connection with the access network device at time t2, and reconnect with the access network device at time t2+5ms; or the terminal device can disconnect the connection with the access network device at time t3, and reconnect with the access network device at time t3+7ms, and so on. The present disclosure does not limit this.

[0115] Optionally, the time pattern can include multiple time pairs, and the time interval between the disconnection time and the connection time in each adjacent two time pairs can be the same.

[0116] For example, the time pair 1, the time pair 2, the time pair 3, and the time pair 4 are arranged in sequence, the disconnection time in the time pair 1 is time t1, the disconnection time in the time pair 2 is time t1+2T, the disconnection time in the time pair 3 is time t1+4T, and the disconnection time in the time pair 4 is time t1+6T. Thus, when the terminal device has a service demand, the terminal device can disconnect the connection with the access network device at time t1; or the terminal device can disconnect the connection with the access network device at time t1+2T; or the terminal device can disconnect the connection with the access network device at time t1+4T; or the terminal device can disconnect the connection with the access network device at time t1+6T, and so on. The present disclosure does not limit this.

[0117] Optionally, the time pattern can include multiple time pairs, and the time interval between the disconnection time and the connection time in each adjacent two time pairs can also be different.

[0118] For example, the time pair 1, the time pair 2, the time pair 3 and the time pair 4 are sequentially arranged, the disconnection moment in the time pair 1 is t1 moment, the disconnection moment in the time pair 2 is t1+T moment, the disconnection moment in the time pair 3 is t1+6T moment, and the disconnection moment in the time pair 4 is t1+8T moment. Therefore, when the terminal device has a service demand, the terminal device can disconnect the connection with the access network device at the t1 moment; or the terminal device can disconnect the connection with the access network device at the t1+T moment; or the terminal device can disconnect the connection with the access network device at the t1+6T moment; or the terminal device can disconnect the connection with the access network device at the t1+8T moment, and the like. The present disclosure does not limit this.

[0119] Optionally, the time pattern can include multiple time pairs, and the time interval between the connection moments in each two adjacent time pairs can be the same.

[0120] For example, the time pair 1, the time pair 2 and the time pair 3 are sequentially arranged, the connection moment in the time pair 1 is t2 moment, the connection moment in the time pair 2 is t2+T moment, and the connection moment in the time pair 3 is t2+2T moment. Therefore, when the terminal device has a service demand, the terminal device can restore the connection with the access network device at the t2 moment; or the terminal device can restore the connection with the access network device at the t2+T moment; or the terminal device can restore the connection with the access network device at the t2+2T moment, and the like. The present disclosure does not limit this.

[0121] Optionally, the time pattern can include multiple time pairs, and the time interval between the connection moments in each two adjacent time pairs can also be different.

[0122] For example, the time pair 1, the time pair 2, the time pair 3 and the time pair 4 are sequentially arranged, the connection moment in the time pair 1 is t3 moment, the connection moment in the time pair 2 is t3+3T moment, the connection moment in the time pair 3 is t3+5T moment, and the connection moment in the time pair 4 is t3+9T moment. Therefore, when the terminal device has a service demand, the terminal device can restore the connection with the access network device at the t3 moment; or the terminal device can restore the connection with the access network device at the t3+3T moment; or the terminal device can restore the connection with the access network device at the t3+5T moment; or the terminal device can restore the connection with the access network device at the t3+9T moment, and the like. The present disclosure does not limit this.

[0123] Optionally, the first indication information can indicate a trigger event of the terminal device disconnecting the connection with the access network device.

[0124] The trigger event can be various, such as paging listening, measurement, reading system message, and the like, and the present disclosure does not limit this.

[0125] For example, the first indication information indicates that the triggering event for the terminal device to disconnect from the access network device is paging monitoring. After receiving the first indication information, the terminal device can disconnect from the access network device when there is a paging monitoring requirement, and the present disclosure does not limit this.

[0126] Optionally, the first indication information can indicate the triggering event for the terminal device to disconnect from the access network device and the disconnection duration corresponding to each triggering event.

[0127] For example, the first indication information indicates that the triggering event for the terminal device to disconnect from the access network device is paging monitoring and measurement, the disconnection duration corresponding to paging monitoring is 1 second (s), and the disconnection duration corresponding to measurement is 20 ms. After receiving the first indication information, the terminal device can disconnect from the current access network device when there is a paging monitoring requirement, and control the disconnection duration within 1 s, or the terminal device can disconnect from the current access network device when there is a measurement requirement, and control the disconnection duration within 20 ms.

[0128] Optionally, the first indication information can indicate the triggering event for the terminal device to disconnect from the access network device and the disconnection time pattern corresponding to each triggering event.

[0129] For example, the first indication information indicates that the triggering event for the terminal device to disconnect from the access network device is paging monitoring and measurement, and the disconnection time pattern corresponding to paging monitoring is 5 ms, 10 ms, and 12 ms, and the disconnection time pattern corresponding to measurement is 3 ms, 7 ms, and 15 ms. If the terminal device receives the first indication information at time t, the terminal device can disconnect from the access network device at time (t+5) ms, or at time (t+10) ms, or at time (t+12) ms when there is a paging monitoring requirement. Alternatively, the terminal device can disconnect from the access network device at time (t+3) ms, or at time (t+7) ms, or at time (t+15) ms when there is a measurement requirement.

[0130] Optionally, the first indication information can indicate the triggering event for the terminal device to disconnect from the access network device and the disconnection time interval corresponding to each triggering event.

[0131] For example, the first indication information indicates that the trigger events for the terminal device to disconnect the connection with the access network device are paging monitoring and reading system messages, and the time interval corresponding to the paging monitoring is 5 ms and the time interval corresponding to the reading system messages is 7 ms. That is, when the terminal device performs the paging monitoring, the time interval between the time points of disconnecting the connection with the access network device for each two times is 5 ms. Or, when the terminal device performs the reading system messages, the time interval between the time points of disconnecting the connection with the access network device for each two times is 7 ms. Therefore, after receiving the first indication information, the terminal device can disconnect the connection with the access network device according to the time interval corresponding to the paging monitoring when there is a paging monitoring demand. Or, the terminal device can disconnect the connection with the access network device according to the time interval corresponding to the reading system messages when there is a reading system messages demand.

[0132] It should be noted that the above examples are only illustrative and cannot be regarded as a limitation on the first indication information in the embodiments of the present disclosure.

[0133] It can be understood that the first indication information can include one of the above or can include multiple, which is not limited by the present disclosure.

[0134] Optionally, the access network device can also send the first indication information to the terminal device through an RRC message, which will not be described herein.

[0135] Optionally, the RRC message can be an RRC reconfiguration (RRC reconfiguration) message, or can be an RRC connection reconfiguration (RRC connection reconfiguration) message, and the like, which is not limited by the present disclosure.

[0136] By implementing the embodiments of the present disclosure, the access network device can send the first indication information to the terminal device to indicate the terminal device to switch the connection configuration. Therefore, the terminal device can disconnect the connection with the access network device according to the indication of the network device, thereby ensuring that the communication transmission of the current connected access network device is not affected, avoiding the failure of other access network services, and improving the reliability of the multi-card terminal device.

[0137] Please refer to Figure 3 , Figure 3 is a flowchart of a control method for switching connection provided by the embodiments of the present disclosure, and the method is executed by an access network device. As shown in Figure 3 , the method can include but is not limited to the following steps:

[0138] In step 31, the first indication information is sent to the terminal device through an RRC message, wherein the first indication information is used to indicate N switching connection configurations to the terminal device, and the terminal device includes at least two user identity modules, wherein N can be a positive integer greater than 1.

[0139] For example, the protocol stipulates that a specific bit can be added in the RRC message to represent the switching connection configuration. Thus, the access network device can send the first indication information to the terminal device through the RRC message, so that the terminal device can learn the switching connection configuration according to the value of the specific bit after receiving the first indication information sent by the access network device, and the like, which is not limited in the present disclosure.

[0140] Optionally, the RRC message can be an RRC reconfiguration message or an RRC connection reconfiguration message, and the like, which is not limited in the present disclosure.

[0141] It should be noted that the content included in the first indication information and the specific implementation manner can refer to the description of other embodiments of the present disclosure, which will not be described here.

[0142] In step 32, the second indication information is sent to the terminal device, wherein the second indication information is used to activate at least one switching connection configuration.

[0143] For example, the switching connection configuration indicated by the first indication information is that the disconnection time of the terminal device from the access network device is 5 ms, and the trigger event of the disconnection of the terminal device from the access network device is paging monitoring. And the second indication information indicates that the terminal device activates the disconnection time from the access network device. Thus, the terminal device can control the disconnection time from the access network device within 5 ms after receiving the second indication information.

[0144] It should be noted that the above examples are only illustrative and cannot be regarded as a limitation on the first indication information and the second indication information in the embodiments of the present disclosure.

[0145] By implementing the embodiments of the present disclosure, the access network device can send the first indication information to the terminal device through the RRC message to indicate N switching connection configurations to the terminal device, and can also send the second indication information to the terminal device to indicate the activation of at least one switching connection configuration to the terminal device. Thus, the terminal device can disconnect the connection with the access network device according to the indication of the network device, so as to ensure that the communication transmission of the current connected access network device is not affected, avoid the failure of other access network services, and improve the reliability of the multi-card terminal device.

[0146] Please refer toFigure 4 , Figure 4 is a flowchart of a control method for switching connection provided by an embodiment of the present disclosure, which is performed by an access network device. As shown in Figure 4 , the method can include but is not limited to the following steps:

[0147] Step 41, receiving third indication information sent by a terminal device, wherein the third indication information contains a trigger event for the terminal device to disconnect from the access network device.

[0148] It can be understood that the trigger event contained in the third indication information can be one or multiple, etc., which is not limited by the present disclosure.

[0149] It should be noted that the specific content of the trigger event can refer to the description of other embodiments of the present disclosure, which will not be described here.

[0150] In the embodiment of the present disclosure, in order to ensure the normal communication transmission, the terminal device can send the third indication information to the access network device. Therefore, after receiving the third indication information sent by the terminal device, the access network device can determine the trigger event for the terminal device to disconnect from the access network device, thereby providing a guarantee for the normal communication transmission.

[0151] Step 42, in response to receiving the switching connection configuration acquisition request sent by the terminal device, sending first indication information to the terminal device, wherein the first indication information is used to indicate the switching connection configuration to the terminal device, and the terminal device includes at least two subscriber identity modules.

[0152] For example, the trigger event indicated by the third indication information is paging listening and measurement, and the first indication information indicates that the duration of the terminal device disconnecting from the access network device is 3ms. Then, when the terminal device has paging listening demand or measurement demand, it can disconnect from the current access network device, and control the duration of disconnecting within 3ms.

[0153] Or, the trigger event indicated by the third indication information is paging listening and measurement, and the first indication information indicates that the disconnecting duration corresponding to the paging listening is 5ms and the disconnecting duration corresponding to the measurement is 8ms. Then, after receiving the first indication information, the terminal device can disconnect from the current access network device when it has paging listening demand, and control the duration of disconnecting within 5ms, or it can also disconnect from the current access network device when it has measurement demand, and control the duration of disconnecting within 8ms.

[0154] Or, the third indication information indicates that the triggering event is paging monitoring and measurement, and the first indication information indicates that the time pattern of the terminal device disconnecting the connection with the access network device is 5 ms, 10 ms, or 12 ms. If the terminal device receives the first indication information at time t, the terminal device can disconnect the connection with the access network device at time (t+5) ms, or at time (t+10) ms, or at time (t+12) ms when there is a paging monitoring demand or a measurement demand.

[0155] Or, the third indication information indicates that the triggering event is paging monitoring and reading system messages, and the first indication information indicates that the time interval corresponding to the paging monitoring is 5 ms and the time interval corresponding to the reading system messages is 7 ms. That is, the terminal device disconnects the connection with the access network device every 5 ms when performing paging monitoring. Or, the terminal device disconnects the connection with the access network device every 7 ms when performing reading system messages. Therefore, after receiving the first indication information, the terminal device can disconnect the connection with the access network device according to the time interval corresponding to the paging monitoring when there is a paging monitoring demand. Or, the terminal device can disconnect the connection with the access network device according to the time interval corresponding to the reading system messages when there is a reading system messages demand.

[0156] Or, the third indication information indicates that the triggering event is paging monitoring and measurement, and the first indication information indicates that the disconnecting time pattern corresponding to the paging monitoring is 5 ms, 10 ms, or 12 ms, and the disconnecting time pattern corresponding to the measurement is 3 ms, 7 ms, or 15 ms. If the terminal device receives the first indication information at time t, the terminal device can disconnect the connection with the access network device at time (t+5) ms, or at time (t+10) ms, or at time (t+12) ms when there is a paging monitoring demand. Or, the terminal device can disconnect the connection with the access network device at time (t+3) ms, or at time (t+7) ms, or at time (t+15) ms when there is a measurement demand.

[0157] It should be noted that the above examples are only illustrative and cannot be used as a limitation on the third indication information, the first indication information, and the like in the embodiments of the present disclosure.

[0158] It should be noted that the content and specific implementation of the first indication information can refer to the description of other embodiments of the present disclosure, and will not be repeated here.

[0159] By implementing the embodiments of the present disclosure, the access network device can first receive the third indication information sent by the terminal device, and in the case of receiving the conversion connection configuration acquisition request sent by the terminal device, send the first indication information to the terminal device to indicate the conversion connection configuration to the terminal device. Therefore, the terminal device can disconnect the connection with the access network device according to the indication of the network device, thereby ensuring that the communication transmission of the currently connected access network device is not affected, avoiding the failure of other access network services, and improving the reliability of the multi-card terminal device.

[0160] Please refer to Figure 5 , Figure 5 is a flowchart of a control method of a conversion connection provided by the embodiments of the present disclosure, and the method is executed by an access network device. As shown in Figure 5 , the method can include but is not limited to the following steps:

[0161] Step 51, in response to establishing a connection with a terminal device, sending first indication information to the terminal device, wherein the first indication information is used to indicate a conversion connection configuration to the terminal device, and the terminal device includes at least two subscriber identity modules.

[0162] Wherein, the access network device can send the first indication information to the terminal device in the case of establishing a connection with the terminal device, so that the terminal device can know the conversion connection configuration according to the first indication information, and perform conversion connection based on the conversion connection configuration. Therefore, it is ensured that the communication transmission of the currently connected access network device is not affected, and the failure of other access network services is avoided, and the reliability of the multi-card terminal device is improved.

[0163] It should be noted that the content and specific implementation manner of the first indication information can refer to the description of other embodiments of the present disclosure, which will not be repeated here.

[0164] Step 52, determining the conversion connection configuration to be activated.

[0165] It can be understood that the number of conversion connection configurations to be activated can be one or multiple, which is not limited by the present disclosure.

[0166] In the embodiments of the present disclosure, the access network device can determine the conversion connection configuration to be activated according to the protocol agreement or the current network state, etc., which is not limited by the present disclosure.

[0167] Step 53, determining the value of each bit in the medium access control layer control unit used to send the second indication information according to the conversion connection configuration to be activated.

[0168] The media access control (MAC) is mainly responsible for controlling the physical medium connected to the physical layer.

[0169] It can be understood that the correspondence between the conversion connection configuration and the bits of the MAC control element (CE) used to send the second indication information can be agreed by a protocol. Then, the values of the bits in the MAC CE used to send the second indication information are determined according to the conversion connection configuration to be activated.

[0170] For example, the protocol agrees that the correspondence between the conversion connection configuration and the bits of the MAC CE used to send the second indication information is a one-to-one correspondence. For example, the first conversion connection configuration corresponds to the first bit of the MAC CE, the second conversion connection configuration corresponds to the second bit of the MAC CE, and so on. The present disclosure does not limit this.

[0171] Optionally, the value of the bit corresponding to the conversion connection configuration to be activated can be taken as 1, and the value of the bit corresponding to the remaining conversion connection configuration not to be activated can be taken as 0. Alternatively, the value of the bit corresponding to the conversion connection configuration to be activated can be taken as a specific numerical value, and so on.

[0172] For example, the conversion connection configurations to be activated are the first and third, respectively, and the values of the first and third bits of the MAC CE can be taken as 1.

[0173] Alternatively, the protocol can agree that a plurality of bits of the MAC CE represent one conversion connection configuration. For example, the MAC CE includes 4 bits, and when the values of the 4 bits are 0001, the first conversion connection configuration is represented; when the values of the 4 bits are 0010, the second conversion connection configuration is represented; when the values of the 4 bits are 0011, the third conversion connection configuration is represented; when the values of the 4 bits are 0100, the fourth conversion connection configuration is represented, and so on.

[0174] It should be noted that the above examples are only illustrative and cannot be regarded as a limitation on the number of bits included in the MAC CE, the values of the bits, and the correspondence between the bits of the MAC CE and the conversion connection configuration, and so on in the embodiments of the present disclosure.

[0175] Optionally, in the embodiments of the present disclosure, the number of bits included in the MAC CE can have two determination methods, and any one of the methods can be agreed by a protocol.

[0176] Optionally, the number of bits included in the MAC CE can be determined based on the following formula (1):

[0177]

[0178] wherein N is the number of conversion connection configurations included in the first indication information, denotes rounding up log2N, denotes rounding up .

[0179] It should be noted that if the formula (1) is used to determine the number of bits contained in the MAC CE, only one conversion connection configuration can be activated at a time through the MAC CE.

[0180] Alternatively, the number of bits contained in the MAC CE can also be determined based on the following formula (2):

[0181]

[0182] wherein N is the number of conversion connection configurations included in the first indication information, denotes rounding up .

[0183] It should be noted that if the formula (2) is used to determine the number of bits contained in the MAC CE, one conversion connection configuration can be activated at a time through the MAC CE, or multiple conversion connection configurations can be activated at a time.

[0184] For example, N is 9, and the number of bits contained in the MAC CE is determined using the formula (1), and the structure of the MAC CE can be as shown in Figure 5A , wherein R is a placeholder, and c1 to c7 are respectively each bit contained in the MAC CE.

[0185] Alternatively, the number of bits contained in the MAC CE is determined using the formula (2), and the structure of the MAC CE can be as shown in Figure 5B , wherein R is a placeholder, and c1 to c15 are respectively each bit contained in the MAC CE.

[0186] It should be noted that the above examples are only illustrative and cannot be used as a limitation on the value of N, the number of bits contained in the MAC CE, etc. in the embodiments of the present disclosure.

[0187] Step 54, sending second indication information to the terminal device through the MAC CE, wherein the second indication information is used to activate at least one conversion connection configuration.

[0188] In the embodiments of the present disclosure, the access network device can send the second indication information to the terminal device through the MAC CE after determining the value of each bit in the MAC CE used to send the second indication information, so as to indicate the terminal device to activate at least one conversion connection configuration. Therefore, the terminal device can activate at least one conversion connection configuration when there is a service demand after receiving the MAC CE.

[0189] By implementing the embodiments of the present disclosure, the access network device can send the first indication information to the terminal device to indicate the terminal device to activate the conversion connection configuration in the case of establishing a connection with the terminal device. The access network device can also determine the conversion connection configuration to be activated, and then determine the value of each bit in the medium access control layer control unit used to send the second indication information according to the conversion connection configuration to be activated, and then send the second indication information to the terminal device through the MAC CE. Therefore, the terminal device can disconnect the connection with the access network device according to the indication of the network device, so as to ensure that the communication transmission of the current connection of the access network device is not affected, avoid the failure of other access network services, and improve the reliability of the multi-card terminal device.
