Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a paging processing method, a paging processing device, a communication device, and a storage medium. Background Technology

[0002] With the development of wireless communication technology, multi-SIM terminal devices are becoming increasingly common in the market. Currently, the processing methods for multi-SIM terminal devices are mainly based on the implementations of various terminal manufacturers. This leads to many different terminal behaviors and processing methods (such as dual-SIM single standby, dual-SIM dual standby single pass, dual-SIM dual standby dual pass, etc.), which may cause some problems. For example, when a multi-SIM terminal device communicates with the first system, it needs to intermittently monitor the second system, such as listening for paging, performing measurements, and reading system messages. This may affect the performance of the first system. If these operations are not performed with the second system, such as not listening for paging, the service on the second system may not be established. When a multi-SIM terminal device receives a paging message on the second system, if the multi-SIM terminal device does not respond to the paging message from the second system, the second system will continue to paging the multi-SIM terminal device until the maximum number of times is reached. This wastes signaling resources and may also trigger error statistics or operations in the second system. Summary of the Invention

[0003] This disclosure provides a paging processing method, paging processing apparatus, communication device, and storage medium, which can be applied to long term evolution (LTE) systems and 5G / NR (New Radio) systems. It can avoid the waste of signaling resources and also avoid erroneous statistics or operations of second network devices.

[0004] In a first aspect, embodiments of this disclosure provide a paging processing method applied to a multi-card terminal device, the method comprising:

[0005] In response to the second user identification card in the multi-card terminal device being in an idle state receiving a paging message sent by the second network device, the first user identification card in the multi-card terminal device being in a connected state sends a first busy indication message to the first core network device;

[0006] The first busy indication information is used to indicate that the multi-card terminal device has received a paging message from the second network device and has decided not to respond for the time being.

[0007] In this technical solution, when the second user identification card in the idle state receives a paging message from the second network device, the first user identification card in the connected state sends a first busy indication message to the first core network device. This first busy indication message indicates that the multi-SIM terminal device has received the paging message from the second network device and has decided not to respond for the time being. This allows the multi-SIM terminal device to inform the second network device of the busy indication message of the idle second user identification card without affecting the communication connection of the first user identification card in the connected state. While maintaining the communication connection of the first user identification card, this avoids the second network device from continuously paging the terminal due to not receiving a response from the multi-SIM terminal device, thus avoiding the waste of signaling resources and preventing erroneous statistics or operations by the second network device.

[0008] In one implementation, when the first user identification card sends a first busy indication message to the first core network device, the method further includes:

[0009] The first user identification card sends the information of the second user identification card to the first core network device; and / or,

[0010] The first user identification card sends information about the second network device to the first core network device; and / or,

[0011] The first user identification card sends information about the second core network device to the first core network device; and / or,

[0012] The first user identification card sends a message to the first core network device explaining why the second user identification card is not responding to the paging of the second network device; and / or,

[0013] The first user identification card sends the duration of the second user identification card's busy status to the first core network device.

[0014] In this technical solution, while the first user identification card sends a first busy indication message to the first core network device, it can also send at least one of the following to the first core network device: information about the second user identification card, information about the second network device, information about the second core network device, the reason for not responding to the paging of the second network device, and the duration of the busy status. This is so that the first core network device can inform the second core network device of the current status of the second user identification card, and the second core network device can decide to suspend paging operations such as paging the second user identification card.

[0015] In one implementation, the step of sending a first busy indication message from the first user identification card in the connected state in the multi-card terminal device to the first core network device includes:

[0016] Determine whether a response is needed to the paging message from the second network device based on preset criteria;

[0017] In response to the multi-card terminal device deciding not to respond to the paging message from the second network device, the second user identification card sends a second busy indication message to the first user identification card; wherein, the second busy indication message is used to indicate that the second user identification card has received the paging message from the second network device and has decided not to respond for the time being;

[0018] After receiving the second busy indication information, the first user identification card sends the first busy indication information to the first core network device.

[0019] In this technical solution, upon receiving a paging message from a second network device, a decision can be made based on certain criteria to determine whether a response to the paging message is necessary. If a response is required, the first user identification card (UIC) does not need to send a first busy indication message to the first core network device. Instead, the first UIC enters an idle state, and the second UIC enters a connected state, enabling the second UIC to communicate with the second network device and thus enabling the services provided by the second network device. If it is determined that a response is not necessary, the first UIC informs the second network device of the busy indication message of the second UIC.

[0020] In one optional implementation, determining whether to respond to the paging message of the second network device based on preset criteria includes:

[0021] Determine whether to respond to the paging message from the second network device based on different service priorities; or...

[0022] Based on the quality of service configuration of the network system corresponding to the first user identification card, determine whether it is necessary to respond to the paging message of the second network device.

[0023] In this technical solution, the need to respond to the paging message of the second network device can be determined based on different service priorities, or based on the quality of service configuration of the network system corresponding to the first user identification card. This allows the terminal device to decide whether to respond to the paging message of the second network device based on the actual situation.

[0024] In one optional implementation, the preset criteria are configured by the network device via Non-Access Stratum (NAS) signaling or Radio Resource Control (RRC) signaling; or, the preset criteria are configured by the multi-card terminal device.

[0025] In one optional implementation, when the second user identification card sends a second busy indication message to the first user identification card, the method further includes:

[0026] The second user identification card sends information about the second user identification card to the first user identification card; and / or,

[0027] The second user identification card sends information about the second network device to the first user identification card; and / or,

[0028] The second user identification card sends information about the second core network device to the first user identification card; and / or,

[0029] The second user identification card sends a reason to the first user identification card for the second user identification card not responding to the paging of the second network device; and / or,

[0030] The second user identification card sends the duration of the second user identification card's busy status to the first user identification card.

[0031] In one implementation, the first core network device and the second core network device are the same core network device.

[0032] In another implementation, the first core network device and the second core network device are different core network devices; wherein, the first core network device sends the first busy indication information sent by the first user identification card to the second core network device.

[0033] In one alternative implementation, the first user identification card sends the first busy indication information via NAS signaling.

[0034] Secondly, embodiments of this disclosure provide a paging processing method applied to a first core network device, the method comprising:

[0035] Receive a first busy indication message from the first user identification card in the connected state in the multi-card terminal device;

[0037] In this technical solution, a multi-SIM terminal device can inform a second network device of the busy indication information of a second user identification card in an idle state without affecting the communication connection of the first user identification card in a connected state. While maintaining the uninterrupted communication connection of the first user identification card, this avoids the second network device from continuously paging the terminal due to not receiving a response from the multi-SIM terminal device, thereby avoiding the waste of signaling resources and also avoiding erroneous statistics or operations by the second network device.

[0038] In one implementation, upon receiving first busy indication information from the first user identification card, the method further includes:

[0041] Receive information from the second core network device sent by the first user identification card; and / or,

[0042] Receive a reason from the first user identification card for not responding to a paging request from the second network device; and / or,

[0043] Receive the duration of the second user identification card being busy, sent from the first user identification card.

[0044] In one implementation, the first core network device and the second core network device are the same core network device.

[0045] In one possible implementation, after receiving the first busy indication information sent from the first user identification card, the method further includes:

[0046] Through the interface between the core network equipment and the network equipment, the second network equipment is instructed to suspend paging of the second user identification card; or...

[0047] Suspend paging of the second user identification card; or,

[0048] Based on the first busy indication information, paging of the second user identification card is suspended.

[0049] In another implementation, the first core network device and the second core network device are different core network devices.

[0050] In one possible implementation, the method further includes:

[0051] The first busy indication information sent by the first user identification card is sent to the second core network device.

[0052] Thirdly, embodiments of this disclosure provide a paging processing method applied to a second core network device, the method comprising:

[0053] Receive busy indication information from the first core network device; wherein, the busy indication information is the first busy indication information received by the first core network device from the first user identification card in the connected state of the multi-card terminal device.

[0055] In one implementation, after receiving busy indication information from the first core network device, the method further includes:

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0096] To better understand the information acquisition method disclosed in this embodiment, the communication system used in this embodiment will be described first.

[0097] Please see Figure 1 , Figure 1This is a schematic diagram of the architecture of a communication system provided in an embodiment of this disclosure. The communication system may include, but is not limited to, a first network device, a second network device, a first core network device, a second core network device, and a terminal device.

[0105] It is understood that the communication system described in the embodiments of this disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and does not constitute a limitation on the technical solutions provided in the embodiments of this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this disclosure are also applicable to similar technical problems.

[0106] The paging processing method, paging processing apparatus, communication device, and storage medium provided in this disclosure will now be described in detail with reference to the accompanying drawings.

[0107] Please see Figure 2 , Figure 2 This is a flowchart of a paging processing method provided in an embodiment of this disclosure. It should be noted that the paging processing method of this embodiment can be applied to multi-SIM terminal devices. As an example, the multi-SIM terminal device may include a first user identification card and a second user identification card. Figure 2 As shown, the paging processing method may include, but is not limited to, the following steps.

[0108] Step 201: In response to the second user identification card in the multi-card terminal device being in an idle state receiving a paging message sent by the second network device, the first user identification card in the multi-card terminal device being in a connected state sends a first busy indication message to the first core network device.

[0109] In this embodiment of the disclosure, the first busy indication information is used to indicate that the multi-card terminal device has received a paging message from the second network device and has decided not to respond for the time being.

[0110] It should be noted that in this embodiment, the first user identification card of the multi-SIM terminal device communicates with the first network device, making the first user identification card a connected state; the second user identification card of the multi-SIM terminal device is in an idle state. When the multi-SIM terminal device is communicating with the first system, it needs to intermittently detect the second system, such as by listening for paging. When the second user identification card in the idle state receives a paging message from the second network device, the first user identification card in the connected state sends a first busy indication message to the first core network device. This first busy indication message indicates that the multi-SIM terminal device has received the paging message from the second network device and has decided not to respond for the time being. This allows the multi-SIM terminal device to inform the second network device of the busy indication message of the second user identification card in the idle state without affecting the communication connection of the first user identification card in the connected state. While maintaining the communication connection of the first user identification card, this avoids the second network device from continuously paging the terminal due to not receiving a response from the multi-SIM terminal device, thus avoiding the waste of signaling resources and preventing erroneous statistics or operations by the second network device.

[0111] Optionally, in other embodiments of this disclosure, the second user identification card of the multi-SIM terminal device can communicate with the second network device, enabling the second user identification card to be in a connected state; the first user identification card of the multi-SIM terminal device is in an idle state. In this embodiment, when the first user identification card in the idle state receives a paging message sent by the first network device, the second user identification card in the connected state sends a busy indication message to the second core network device. This busy indication message indicates that the multi-SIM terminal device has received the paging message from the first network device and has decided not to respond for the time being. This allows the multi-SIM terminal device to inform the first network device of the busy indication message of the first user identification card in the idle state without affecting the communication connection of the second user identification card in the connected state. While maintaining the uninterrupted communication connection of the second user identification card, this avoids the first network device from continuously paging the terminal due to not receiving a response from the multi-SIM terminal device, thereby avoiding the waste of signaling resources and preventing erroneous statistics or operations by the first network device.

[0112] In other words, when a user identification card in an idle state in a multi-SIM terminal device in this embodiment receives a paging message from a corresponding network device, the user identification card in a connected state in the multi-SIM terminal device can send a busy indication message to the corresponding network device to indicate that the multi-SIM terminal device has received the paging message from the network device corresponding to the user identification card in the idle state and has decided not to respond for the time being. This allows the multi-SIM terminal device to inform the corresponding network device of the busy indication message of the user identification card in the idle state without affecting the communication connection of the user identification card in the connected state. This avoids the network device from continuously paging the terminal due to not receiving a response from the multi-SIM terminal device, thereby avoiding the waste of signaling resources and also avoiding incorrect statistics or operations by the network device.

[0113] To facilitate the description and understanding of the embodiments of this disclosure, the following embodiments will take the case where the first user identification card of a multi-card terminal device communicates with the first network device and the second user identification card is in an idle state as an example to introduce the paging processing method provided by the embodiments of this disclosure.

[0114] It should be noted that after receiving a paging message from the second network device, the second SIM card in a multi-SIM terminal device needs to determine whether to respond to the paging message based on certain criteria. Optionally, please refer to [link to relevant documentation]. Figure 3 , Figure 3 This is a flowchart of another paging processing method provided in this disclosure. It should be noted that the paging processing method of this disclosure can be applied to multi-SIM terminal devices. As an example, the multi-SIM terminal device may include a first user identification card and a second user identification card. Figure 3 As shown, the paging processing method may include, but is not limited to, the following steps.

[0115] In some embodiments of the present disclosure, the paging processing method may include step 301, in response to a second user identification card in an idle state in a multi-card terminal device receiving a paging message sent by a second network device, determining whether it is necessary to respond to the paging message of the second network device according to a preset criterion.

[0116] In some embodiments of this disclosure, when a second user identification card in an idle state receives a paging message from a second network device in a multi-SIM terminal device, the second user identification card can determine whether it needs to respond to the paging message from the second network device according to preset criteria, and send the determination result to the multi-SIM terminal device so that the multi-SIM terminal device knows whether the second user identification card needs to respond to the paging message from the second network device or not. Alternatively, in other embodiments of this disclosure, when a second user identification card in an idle state receives a paging message from a second network device in a multi-SIM terminal device, the second user identification card sends relevant information to the multi-SIM terminal device, and the multi-SIM terminal device determines whether it needs to respond to the paging message from the second network device according to preset criteria and the relevant information sent by the second user identification card.

[0117] It should be noted that there are multiple ways to implement the determination of whether to respond to the paging message of the second network device based on preset criteria in this embodiment. The difference between these implementations mainly lies in the content of the preset criteria. Two different examples will be given below to illustrate how to determine whether to respond to the paging message of the second network device:

[0118] Example 1

[0119] Determine whether to respond to the paging message from the second network device based on different service priorities.

[0120] In this example, the preset criteria can be different service priorities. For instance, when a second user identification card in an idle state receives a paging message from a second network device in a multi-SIM terminal device, it can determine whether the second user identification card needs to respond to the paging message based on different service priorities. Here, the service can be understood as a game service or an incoming call service. Assuming the game service has a higher priority than the incoming call service, when the idle second user identification card receives a paging message from the second network device, since the game service has a higher priority than the incoming call service, it can be determined that the second user identification card will not respond to the paging message.

[0121] Example 2

[0122] Based on the quality of service configuration of the network system corresponding to the first user identification card, determine whether it is necessary to respond to the paging message of the second network device.

[0123] In this example, the preset criterion can be the QoS (Quality of Service) configuration of the network system corresponding to the first user identification card. For example, when the second user identification card, which is in an idle state in a multi-card terminal device, receives a paging message sent by the second network device, it can determine whether the second user identification card needs to respond to the paging message of the second network device based on the QoS configuration of the network system corresponding to the first user identification card.

[0124] For example, assuming a throughput threshold is configured in the QoS settings, if the throughput of the network system corresponding to the first user identification card (SIM card) exceeds the throughput threshold in the QoS settings, it can be determined that the second SIM card needs to respond to the paging message of the second network device. Similarly, assuming a latency threshold is configured in the QoS settings, if the latency of the network system corresponding to the first SIM card is greater than the latency threshold in the QoS settings, it can be determined that the second SIM card needs to respond to the paging message of the second network device. Furthermore, assuming both throughput and latency thresholds are configured in the QoS settings, if the throughput of the network system corresponding to the first SIM card exceeds the throughput threshold in the QoS settings, and / or the latency of the network system corresponding to the first SIM card exceeds the latency threshold in the QoS settings, it can be determined that the second SIM card needs to respond to the paging message of the second network device; if the throughput of the network system corresponding to the first SIM card does not exceed the throughput threshold in the QoS settings, and the latency of the network system corresponding to the first SIM card does not exceed the latency threshold in the QoS settings, it can be determined that the second SIM card does not need to respond to the paging message of the second network device.

[0125] In some embodiments of this disclosure, the preset criteria can be configured by the network device via NAS (Non-access stratum) signaling or RRC (Radio Resource Control) signaling. For example, the preset criteria can be configured by the first network device via NAS or RRC signaling, and then the configured preset criteria can be sent to the second system for use. Alternatively, the preset criteria can be directly configured by the second network device via NAS or RRC signaling, so that the second user identification card can determine whether to respond to the paging message of the second network device based on the preset criteria.

[0126] In other embodiments of this disclosure, the preset criteria can be configured by a multi-SIM terminal device. For example, it can be configured directly by the multi-SIM terminal device to determine whether to respond to the paging message of the second network device based on different service priorities; or it can be configured directly by the multi-SIM terminal device to determine whether to respond to the paging message of the second network device based on the QoS configuration of the network system corresponding to the first user identification card.

[0127] Optionally, when the second user identification card in the idle state receives a paging signaling sent by the second network device, and determines that it needs to respond to the paging message of the second network device according to a preset criterion, the second user identification card communicates with the second network device, while the first user identification card remains in the idle state.

[0128] In some embodiments according to this disclosure, the paging processing method may include step 302, in response to the multi-SIM terminal device deciding not to respond to the paging message from the second network device, the second user identification card sends a second busy indication message to the first user identification card. The second busy indication message indicates that the second user identification card has received the paging message from the second network device and has decided not to respond for the time being.

[0129] Optionally, when deciding that the second user identification card will not respond to the paging message of the second network device, the second user identification card sends a second busy indication message to the first user identification card. The second busy indication message indicates that the second user identification card has received the paging message of the second network device or the second core network device, but has decided not to respond for the time being.

[0130] It should be noted that the first user identification card in this embodiment can receive the second busy indication information through different means; that is, the transmission path of the second busy indication information can be multiple. As one example, the second busy indication information can be sent by the second user identification card to the processor of the multi-card terminal device, and then sent by the processor to the first user identification card. As another example, the second busy indication information can be sent directly from the second user identification card to the first user identification card.

[0131] It should be noted that, in this embodiment of the disclosure, when the second user identification card sends the second busy indication information to the first user identification card, it may also send other information simultaneously. In one implementation, when the second user identification card sends the second busy indication information to the first user identification card, the second user identification card may also send information about itself to the first user identification card, and / or send information about the second network device to the first user identification card, and / or send information about the second core network device to the first user identification card, and / or send the reason why the second user identification card does not respond to the paging of the second network device to the first user identification card, and / or send the duration of the second user identification card's busy status to the first user identification card.

[0132] In other words, when the second user identification card sends the second busy indication information to the first user identification card, it can also simultaneously send information about the second user identification card, and / or information about the second network device, and / or information about the second core network device, and / or the reason for not responding to the paging of the second network device, and / or the duration of the busy period, etc.

[0133] In some embodiments according to this disclosure, the paging processing method may include step 303, in which the first user identification card sends a first busy indication message to the first core network device after receiving the second busy indication message.

[0134] The first busy indication message indicates that the multi-card terminal device has received a paging message from the second network device and has decided not to respond for the time being.

[0135] In other words, after receiving the second busy indication information from the second user identification card, the first user identification card sends the first busy indication information to the first core network device, indicating that the multi-card terminal device has received the paging message from the second network device or the second core network device, but decides not to respond for the time being.

[0136] It should be noted that, in this embodiment of the disclosure, when the first user identification card sends the first busy indication information to the first core network device, it may also send other information simultaneously. In one implementation, when the first user identification card sends the first busy indication information to the first core network device, it may also send information about the second user identification card to the first core network device, and / or send information about the second network device to the first core network device, and / or send information about the second core network device to the first core network device, and / or send the reason why the second user identification card does not respond to the paging of the second network device to the first core network device, and / or send the duration of the second user identification card being busy to the first core network device.

[0137] In other words, when the first user identification card sends the first busy indication information to the first core network device, it can also simultaneously send information about the second user identification card, and / or information about the second network device, and / or information about the second core network device, and / or the reason for not responding to the paging of the second network device, and / or the duration of the busy period, etc.

[0138] In one implementation, the first user identification card can send the first busy indication information to the first network device via NAS signaling. As an example, the first busy indication information can be sent to the first network device by modifying the Mobility Registration Update signaling.

[0139] It should be noted that in some embodiments of this disclosure, the first core network device and the second core network device can be the same core network device. That is, when the second user identification card receives a paging message from the second network device, the first user identification card sends a busy indication to the first core network device to indicate that the multi-SIM terminal device has received the paging message from the second network device and has decided not to respond. Since the first and second core network devices are the same core network device, when the first core network device receives the busy indication from the first user identification card, the second core network device also knows that the second user identification card has received the paging message from the second network device but has decided not to respond. This allows the multi-SIM terminal device to inform the second network of the busy indication information of the second user identification card without affecting the communication connection of the first user identification card. While maintaining the uninterrupted communication connection of the first user identification card, this avoids the second network device continuously paging the terminal due to not receiving a response from the multi-SIM terminal device, thus avoiding waste of signaling resources and preventing erroneous statistics or operations by the second network device.

[0140] In other embodiments of this disclosure, the first core network device and the second core network device can be different core network devices. To ensure the second core network device knows that the second user identification card has received a paging message from the second network device but has decided not to respond, the first core network device can send a first busy indication message sent by the first user identification card to the second core network device. That is, when the first core network device and the second core network device are different core network devices, after the first user identification card receives the second busy indication message sent by the second user identification card, it sends the first busy indication message to the first network device. Upon receiving the first busy indication message from the first user identification card, the first core network device sends it to the second core network device, allowing the second core network device to know that the second user identification card has received a paging message from the second network device but has decided not to respond.

[0141] It should be understood that Figure 3 The illustration shows a case where steps 301 to 303 are combined and performed sequentially. However, those skilled in the art will understand that the above steps can be performed individually as needed. For example, the implementation of step 302 is not contingent upon step 301.

[0142] It is understood that the above embodiments describe the implementation of the paging processing method of this disclosure from the perspective of a multi-card terminal device. This disclosure also proposes another paging processing method, the implementation of which will be described below from the perspective of a first core network device. Please refer to... Figure 4 , Figure 4This is a flowchart of another paging processing method provided in this disclosure. It should be noted that the paging processing method of this disclosure can be applied to a first core network device. For example... Figure 4 As shown, the paging processing method may include, but is not limited to, the following steps.

[0143] Step 401: Receive first busy indication information from the first user identification card in the connected state of the multi-card terminal device; wherein, the first busy indication information is used to indicate that the multi-card terminal device has received the paging message from the second network device and has decided not to respond for the time being; the second network device is the network device corresponding to the second user identification card in the idle state of the multi-card terminal device.

[0144] For example, a multi-SIM terminal device's first SIM card communicates with a first network device, placing the first SIM card in a connected state; the second SIM card in the multi-SIM terminal device is in an idle state. While communicating with the first system, the multi-SIM terminal device needs to intermittently monitor the second system, such as by listening for paging messages. When the idle second SIM card receives a paging message from the second network device, the connected first SIM card sends a first busy indication message to the first core network device. The first core network device receives this first busy indication message, indicating that the multi-SIM terminal device has received the paging message from the second network device and has decided not to respond. This allows the multi-SIM terminal device to inform the second network device of the busy indication message of the idle second SIM card without affecting the communication connection of the connected first SIM card. While maintaining the uninterrupted communication connection of the first SIM card, this avoids the second network device continuously paging the terminal due to a lack of response, thus preventing waste of signaling resources and errors in the second network device's statistics or operations.

[0145] It should be noted that when the first user identification card sends the first busy indication information to the first core network device, it can also send other information simultaneously. In one implementation, when the first user identification card sends the first busy indication information to the first core network device, it can also send information about the second user identification card, and / or, information about the second network device, and / or, information about the second core network device, and / or, the reason why the second user identification card is not responding to the paging of the second network device, and / or, the duration of the second user identification card's busy status. The aforementioned other information can be sent from the second user identification card to the first user identification card simultaneously with the second busy indication information sent from the second user identification card to the first user identification card; this will be further explained below.

[0146] It should be noted that in some embodiments of this disclosure, the first core network device and the second core network device can be the same core network device. That is, when the first core network device receives a first busy indication message from the first user identification card, since the first core network device and the second core network device are the same core network device, the second core network device also knows that the second user identification card has received a paging message from the second network device, but decides not to respond temporarily. After receiving the first busy indication message from the first user identification card, the first core network device can instruct the second network device to suspend paging of the second user identification card through the interface between the core network device and the network device. Alternatively, the first core network device can directly suspend paging of the second user identification card after receiving the first busy indication message from the first user identification card. Alternatively, after receiving a first busy indication message from the first user identification card, the first core network device can suspend paging the second user identification card based on the busy duration in the first busy indication message. For example, if the busy duration in the first busy indication message is 5 minutes, it means that the second user identification card will not respond to paging within these 5 minutes, and the first core network device will suspend paging the second user identification card within these 5 minutes.

[0147] In other embodiments of this disclosure, the first core network device and the second core network device can be different core network devices. To ensure the second core network device knows that the second user identification card has received a paging message from the second network device but has decided not to respond, the first core network device can send a first busy indication message sent by the first user identification card to the second core network device. That is, when the first core network device and the second core network device are different core network devices, after the first user identification card receives the second busy indication message sent by the second user identification card, it sends the first busy indication message to the first core network device. Upon receiving the first busy indication message from the first user identification card, the first core network device sends it to the second core network device, allowing the second core network device to know that the second user identification card has received a paging message from the second core network device but has decided not to respond.

[0148] By implementing the embodiments of this disclosure, a multi-SIM terminal device can inform the second network of the busy indication information of the second user identification card in the idle state without affecting the communication connection of the first user identification card in the connected state. While maintaining the communication connection of the first user identification card, the second network can avoid continuously paging the terminal due to not receiving a response from the multi-SIM terminal device, thereby avoiding the waste of signaling resources and also avoiding erroneous statistics or operations by the second network.

[0149] It is understood that the above embodiments describe the implementation of the paging processing method of this disclosure from the perspective of the first core network device. This disclosure also proposes another paging processing method, the implementation of which will be described below from the perspective of the second core network device. Please refer to... Figure 5 , Figure 5 This is a flowchart of another paging processing method provided in this disclosure embodiment. It should be noted that the paging processing method of this disclosure embodiment can be applied to a second core network device.

[0150] It should also be noted that the first core network device and the second core network device in this embodiment are not the same core network device. For example... Figure 5 As shown, the paging processing method may include, but is not limited to, the following steps.

[0151] Step 501: Receive busy indication information from the first core network device; wherein, the busy indication information is the first busy indication information received by the first core network device from the first user identification card in the connected state of the multi-card terminal device.

[0152] The first busy indication information is used to indicate that the multi-card terminal device has received the paging message from the second network device and has decided not to respond for the time being; the second network device is the network device corresponding to the second user identification card in the multi-card terminal device that is in an idle state.

[0153] For example, when a second user identification card in an idle state receives a paging message from a second network device in a multi-SIM terminal device, the second user identification card can determine whether it needs to respond to the paging message from the second network device according to preset criteria, and send the determination result to the multi-SIM terminal device so that the multi-SIM terminal device knows whether the second user identification card needs to respond to the paging message from the second network device or not. Alternatively, in other embodiments of this disclosure, when a second user identification card in an idle state receives a paging message from a second network device in a multi-SIM terminal device, the second user identification card sends relevant information to the multi-SIM terminal device, and the multi-SIM terminal device determines whether it needs to respond to the paging message from the second network device according to preset criteria and the relevant information sent by the second user identification card.

[0154] Optionally, when the second user identification card decides not to respond to the paging message from the second network device, the second user identification card sends a second busy indication message to the first user identification card to indicate that the second user identification card has received the paging message from the second network device or the second core network device, but has decided not to respond for the time being. After receiving the second busy indication message from the second user identification card, the first user identification card sends a first busy indication message to the first core network device to indicate that the multi-card terminal device has received the paging message from the second network device or the second core network device, but has decided not to respond for the time being.

[0155] In this embodiment, since the first core network device and the second core network device are not the same core network device, in order for the second core network device to know that the second user identification card has received a paging message from the second network device but has decided not to respond temporarily, the first core network device can send a first busy indication message sent by the first user identification card to the second core network device. That is, when the first core network device and the second core network device are different core network devices, after the first user identification card receives the second busy indication message sent by the second user identification card, it sends the first busy indication message to the first core network device. After receiving the first busy indication message sent by the first user identification card, the first core network device sends the first busy indication message to the second core network device, thereby enabling the second core network device to receive the busy indication message sent by the first core network device and to know that the second user identification card has received a paging message from the second network device but has decided not to respond temporarily.

[0156] Optionally, while receiving the busy indication information sent by the first core network device, the second core network device may also receive information about the second user identification card sent by the first core network device; and / or, receive information about the second network device sent by the first core network device; and / or, receive information about the second core network device sent by the first core network device; and / or, receive the reason for not responding to the paging of the second network device sent by the first core network device; and / or, receive the duration of the second user identification card being busy sent by the first core network device.

[0157] It should be noted that, in some embodiments of this disclosure, after receiving a busy indication message from the first core network device, the second core network device can, through the interface between the core network device and the network device, instruct the second network device to suspend paging of the second user identification card. Alternatively, after receiving a busy indication message from the first core network device, the second core network device can suspend paging of the second user identification card. Or, after receiving a busy indication message from the first core network device, the second core network device can suspend paging of the second user identification card based on the first busy indication message. For example, if the busy duration in the first busy indication message is 5 minutes, it indicates that the second user identification card will not respond to paging during these 5 minutes, and the second core network device will suspend paging of the second user identification card during these 5 minutes.

[0158] By implementing the embodiments of this disclosure, a multi-SIM terminal device can inform the second network of the busy indication information of the second user identification card in the idle state without affecting the communication connection of the first user identification card in the connected state. While maintaining the communication connection of the first user identification card, the second network can avoid continuously paging the terminal due to not receiving a response from the multi-SIM terminal device, thereby avoiding the waste of signaling resources and also avoiding erroneous statistics or operations by the second network.

[0159] In the embodiments provided above, the methods provided by the present disclosure have been described from the perspectives of a multi-SIM terminal device, a first core network device, and a second core network device. To implement the functions of the methods provided in the embodiments of the present disclosure, the multi-SIM terminal device, the first core network device, and the second core network device may include hardware structures and software modules, and may implement the above functions in the form of hardware structures, software modules, or a combination of hardware structures and software modules. One of the above functions may be executed in the form of hardware structures, software modules, or a combination of hardware structures and software modules.

[0160] Please see Figure 6 , Figure 6 This is a schematic diagram of the structure of a paging processing device 60 provided in an embodiment of the present disclosure. Figure 6 The paging processing device 60 shown may include a transceiver module 601. The transceiver module 601 may include a sending module and / or a receiving module. The sending module is used to implement the sending function, and the receiving module is used to implement the receiving function. The transceiver module 601 can implement both sending and / or receiving functions.

[0161] The paging processing device 60 can be a multi-SIM terminal device, a device within a multi-SIM terminal device, or a device compatible with a multi-SIM terminal device. Alternatively, the paging processing device 60 can be a first core network device, a device within a first core network device, or a device compatible with a first core network device.

[0164] In one optional implementation, the transceiver module 601 is specifically used to: determine whether it is necessary to respond to the paging message of the second network device according to a preset criterion; in response to the multi-card terminal device deciding not to respond to the paging message of the second network device, the second user identification card sends a second busy indication message to the first user identification card; wherein, the second busy indication message is used to indicate that the second user identification card has received the paging message of the second network device and has decided not to respond for the time being; after receiving the second busy indication message, the first user identification card sends a first busy indication message to the first core network device.

[0165] Optionally, the transceiver module 601 is specifically used to: determine whether it is necessary to respond to the paging message of the second network device based on different service priorities; or, determine whether it is necessary to respond to the paging message of the second network device based on the quality of service configuration of the network system corresponding to the first user identification card.

[0167] As an example, the transceiver module 601 is also configured to: send information about the second user identification card to the first user identification card when the second user identification card sends a second busy indication information to the first user identification card; and / or, send information about the second network device to the first user identification card; and / or, send information about the second core network device to the first user identification card; and / or, send the reason why the second user identification card does not respond to the paging of the second network device to the first user identification card; and / or, send the duration of the second user identification card being busy to the first user identification card.

[0168] In one implementation, the first core network device and the second core network device are the same core network device.

[0169] In another implementation, the first core network device and the second core network device are different core network devices; wherein, the first core network device sends the first busy indication information sent by the first user identification card to the second core network device.

[0170] In this embodiment of the disclosure, the first user identification card sends a first busy indication message via NAS signaling.

[0171] The paging processing device 60 is a first core network device: In this embodiment of the present disclosure, the transceiver module 601 is used to receive a first busy indication information sent from the first user identification card in the connected state of the multi-card terminal device; wherein, the first busy indication information is used to indicate that the multi-card terminal device has received the paging message of the second network device and has decided not to respond for the time being; the second network device is the network device corresponding to the second user identification card in the idle state of the multi-card terminal device.

[0172] In one implementation, the transceiver module 601 is further configured to: receive information about a second user identification card from the first user identification card when receiving a first busy indication information from the first user identification card; and / or receive information about a second network device from the first user identification card; and / or receive information about a second core network device from the first user identification card; and / or receive a reason for not responding to a paging request from the second network device from the first user identification card; and / or receive the duration of the second user identification card being busy from the first user identification card.
