Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to an information transmission method, apparatus, user equipment, access network equipment, core network, and storage medium. Background Technology

[0002] With the rapid development of wireless communication technology and mobile terminals, multi-SIM terminal technology has been widely applied. A multi-SIM terminal can be configured with multiple SIM (Subscriber Identity Module) cards, each corresponding to a different communication system, allowing the terminal to simultaneously enjoy services provided by multiple communication systems. Furthermore, each SIM card in a multi-SIM terminal typically receives paging messages from the network side to perform corresponding services based on the received paging messages. This inevitably leads to paging conflicts, i.e., situations where two SIM cards receive paging messages at conflicting times.

[0003] In related technologies, when paging conflicts occur in multi-SIM terminals, the terminals determine paging priority based on user-configured rules. However, these user-configured rules are subjective and lack data support, which may cause the multi-SIM terminals to miss important paging messages, resulting in irreparable losses. Summary of the Invention

[0004] The information transmission method, apparatus, user equipment, access network equipment, core network, and storage medium disclosed herein are intended to address the technical problem in related technologies where multi-card terminals are prone to missing important paging messages when paging conflicts occur.

[0005] The information transmission method proposed in one embodiment of this disclosure is applied to an access network device and includes:

[0006] Send first indication information and / or core network information to the user equipment (UE), wherein the first indication information is used to indicate whether the core network to which the access network device is connected supports sending paging reasons, and the core network information includes information of the core network that supports sending paging reasons.

[0007] The information transmission method proposed in another embodiment of this disclosure, applied to a core network, includes:

[0008] A second indication message is sent to the UE via non-access stratum (NAS) signaling. The second indication message is used to indicate whether the core network supports sending a paging reason.

[0009] Another embodiment of this disclosure proposes an information transmission method, applied to a UE, including:

[0015] Another embodiment of this disclosure provides an information transmission apparatus, including:

[0016] A receiving module is configured to receive information, the information including at least one of the following: first indication information sent by the access network device, core network information sent by the access network device, and second indication information sent by the core network; wherein, the first indication information is used to indicate whether the core network to which the access network device is connected supports sending a paging reason, and the core network information includes information of the core network that supports sending a paging reason; the second indication information is used to indicate whether the core network sending the second indication information supports sending a paging reason.

[0017] Another aspect of this disclosure provides a user equipment comprising: a transceiver; a memory; and a processor, respectively connected to the transceiver and the memory, configured to control the transmission and reception of wireless signals of the transceiver by executing computer-executable instructions on the memory, and capable of implementing the method proposed in the other aspect of the above embodiment.

[0018] Another aspect of this disclosure provides an access network device, comprising: a transceiver; a memory; and a processor, respectively connected to the transceiver and the memory, configured to control the wireless signal transmission and reception of the transceiver by executing computer-executable instructions on the memory, and capable of implementing the method proposed in the preceding aspect of the embodiment.

[0019] Another aspect of this disclosure provides a core network, comprising: a transceiver; a memory; and a processor, respectively connected to the transceiver and the memory, configured to control the wireless signal transmission and reception of the transceiver by executing computer-executable instructions on the memory, and capable of implementing the method proposed in the other aspect of the above disclosure.

[0020] In another aspect of this disclosure, a computer storage medium is provided, wherein the computer storage medium stores computer-executable instructions; the computer-executable instructions, when executed by a processor, can implement the method described above.

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of this disclosure as detailed in the appended claims.

[0047] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. The singular forms “a” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0048] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, and similarly, second information may also be referred to as first information. Depending on the context, the words “if” and “suppose” as used herein may be interpreted as “when”, “when”, or “in response to a determination”.

[0049] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. 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.

[0050] In the information transmission method provided in this embodiment, the access network device can send first indication information and / or core network information to the UE. The first indication information indicates whether the core network connected to the access network device supports sending paging reasons, and the core network information includes information about the core network that supports sending paging reasons. Therefore, in this embodiment, the UE can obtain information about the core network that supports sending paging reasons. Based on this, when a core network that supports sending paging reasons sends a paging message to a multi-SIM UE, it can simultaneously send the paging reason corresponding to the paging message to the multi-SIM UE. Then, when a paging conflict occurs, the multi-SIM UE can determine the priority of the paging message based on the paging reason, thereby avoiding missing important paging messages and reducing losses.

[0051] The information transmission method, apparatus, user equipment, access network equipment, core network and storage medium provided in this disclosure are described in detail below with reference to the accompanying drawings.

[0052] Figure 1 This is a flowchart illustrating an information transmission method provided in an embodiment of the present disclosure, applied to an access network device, such as... Figure 1 As shown, the information transmission method may include the following steps:

[0053] Step 101: Send the first instruction information and / or core network information to the UE (User Equipment).

[0054] It should be noted that the information transmission method of this disclosure can be applied to any UE. The UE can be a device that provides voice and / or data connectivity to a user. The UE can communicate with one or more core networks via a RAN (Radio Access Network). The UE can be an IoT terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, or user agent. Alternatively, the UE can also be a device in an unmanned aerial vehicle. Alternatively, the UE can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless terminal connected to an external vehicle computer. Alternatively, the UE can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0055] Furthermore, in one embodiment of this disclosure, the first indication information can be used to indicate whether the core network to which the access network device is connected supports sending a paging reason. In one embodiment of this disclosure, the access network device can be an access network device that communicates with the UE. In one embodiment of this disclosure, the access network device can be a base station.

[0056] Furthermore, in one embodiment of this disclosure, the access network device can be connected to one core network. In another embodiment of this disclosure, the access network device can be connected to multiple core networks. In one embodiment of this disclosure, when the access network device is connected to multiple core networks, the first indication information can be used to indicate whether any one of the multiple core networks supports sending a paging reason; in another embodiment of this disclosure, when the access network device is connected to multiple core networks, the first indication information can be used to indicate whether any multiple core networks support sending a paging reason.

[0057] Furthermore, in one embodiment of this disclosure, the core network information may include information about the core network that supports sending paging reasons. In one embodiment of this disclosure, the core network information may include information about at least one core network. In one embodiment of this disclosure, the core network may be a core network connected to the access network device. In one embodiment of this disclosure, the core network information may be the core network's ID (identification number).

[0058] Therefore, in one embodiment of this disclosure, the access network device can directly send first indication information and / or core network information to the UE to notify the UE which core networks in the core network to which the access network device is connected specifically support sending paging reasons.

[0059] It should be noted that, in one embodiment of this disclosure, the UE can be a multi-SIM UE. Furthermore, in one embodiment of this disclosure, when the UE is a multi-SIM UE and at least two SIM cards are active, the access network device can use the information transmission method provided in this embodiment to send first indication information and / or core network information to the UE. This is so that when the first indication information and / or core network information indicate that the core network to which the access network device is connected supports sending a paging reason, the core network can simultaneously send a paging reason when subsequently sending a paging message to the UE. Therefore, when a paging conflict occurs again, the UE can determine the paging priority based on the paging reason.

[0060] Furthermore, in another embodiment of this disclosure, when the UE is a single-card UE, or when the UE is a multi-card UE but only one card is activated, since no paging conflict will occur, the access network device does not need to send the first indication information and / or core network information to the UE.

[0061] In summary, in the information transmission method provided in this embodiment, the access network device can send first indication information and / or core network information to the UE. The first indication information indicates whether the core network connected to the access network device supports sending paging reasons, and the core network information includes information about the core network that supports sending paging reasons. Therefore, in this embodiment, the UE can obtain information about the core network that supports sending paging reasons. Based on this, when a core network that supports sending paging reasons sends a paging message to a multi-SIM UE, it can simultaneously send the paging reason corresponding to the paging message to the multi-SIM UE. Then, when a paging conflict occurs, the multi-SIM UE can determine the priority of the paging message based on the paging reason, thereby avoiding missing important paging messages and reducing losses.

[0062] Figure 2 This is a flowchart illustrating an information transmission method provided in another embodiment of the present disclosure, applied to an access network device, such as... Figure 2 As shown, the information transmission method may include the following steps:

[0063] Step 201: Send the first indication information and / or core network information to the UE via system messages.

[0064] In one embodiment of this disclosure, detailed information about the UE, the first indication information, and the core network information can be found in the first embodiment described above, and will not be repeated here.

[0065] Furthermore, in one embodiment of this disclosure, system messages may include: MSI (Minimum SI) and OSI (Other SI).

[0066] In one embodiment of this disclosure, when the system message is MSI, the access network device can directly send first indication information and / or core network information to the UE via MSI. Furthermore, in another embodiment of this disclosure, the access network device can broadcast first indication information and / or core network information via MSI.

[0067] In one embodiment of this disclosure, when the system message is OSI, the access network device can directly send first indication information and / or core network information to the UE via OSI. Further, in one embodiment of this disclosure, the access network device can broadcast the first indication information and / or core network information via OSI. In another embodiment of this disclosure, the access network device can receive a first request message sent by the UE, and then send the first indication information and / or the core network information to the UE via OSI according to the first request message sent by the UE.

[0068] In summary, in the information transmission method provided in this embodiment, the access network device can send first indication information and / or core network information to the UE. The first indication information indicates whether the core network connected to the access network device supports sending paging reasons, and the core network information includes information about the core network that supports sending paging reasons. Therefore, in this embodiment, the UE can obtain information about the core network that supports sending paging reasons. Based on this, when a core network that supports sending paging reasons sends a paging message to a multi-SIM UE, it can simultaneously send the paging reason corresponding to the paging message to the multi-SIM UE. Then, when a paging conflict occurs, the multi-SIM UE can determine the priority of the paging message based on the paging reason, thereby avoiding missing important paging messages and reducing losses.

[0069] Figure 3 This is a flowchart illustrating an information transmission method provided in another embodiment of the present disclosure, applied to an access network device, such as... Figure 3 As shown, the information transmission method may include the following steps:

[0070] Step 301: Send the first indication information to the UE via RRC (Radio Resource Control) signaling.

[0071] In one embodiment of this disclosure, detailed descriptions of the UE, the first indication information, and the core network information are provided in the first embodiment described above, and will not be repeated here.

[0072] Furthermore, in one embodiment of this disclosure, the access network speed device can send first indication information to the UE via unicast RRC signaling.

[0073] It should be noted that, in one embodiment of this disclosure, in an NR (New Radio) system, the access network device can send first indication information to the UE via RRC Setup signaling and / or RRC Resume signaling and / or RRC Reestablishment signaling and / or RRC Reconfiguration signaling.

[0074] Furthermore, in another embodiment of this disclosure, in an LTE (Long Term Evolution) system, the access network device may send first indication information to the UE via RRC Connection Setup signaling and / or RRC Connection Reestablishment signaling and / or RRC Connection Reconfiguration signaling.

[0075] Furthermore, it should be noted that in one embodiment of this disclosure, the access network device can also send core network information to the UE via RRC signaling. Also, in one embodiment of this disclosure, the access network device can use the same sending method as described above for sending the first indication information to send core network information.

[0076] In summary, in the information transmission method provided in this embodiment, the access network device can send first indication information and / or core network information to the UE. The first indication information indicates whether the core network connected to the access network device supports sending paging reasons, and the core network information includes information about the core network that supports sending paging reasons. Therefore, in this embodiment, the UE can obtain information about the core network that supports sending paging reasons. Based on this, when a core network that supports sending paging reasons sends a paging message to a multi-SIM UE, it can simultaneously send the paging reason corresponding to the paging message to the multi-SIM UE. Then, when a paging conflict occurs, the multi-SIM UE can determine the priority of the paging message based on the paging reason, thereby avoiding missing important paging messages and reducing losses.

[0077] Figure 4 This is a flowchart illustrating an information transmission method provided in yet another embodiment of the present disclosure, applied to an access network device, such as... Figure 4 As shown, the information transmission method may include the following steps:

[0078] Step 401: Obtain the second request message sent by the UE via RRC signaling.

[0079] In one embodiment of this disclosure, a detailed description of the UE can be found in the first embodiment described above, and will not be repeated here.

[0080] Furthermore, in one embodiment of this disclosure, the second request message may include information about the core network queried by the UE (e.g., the ID of the queried core network). In one embodiment of this disclosure, the core network queried by the UE may be included in the core network connected to the access network device. In one embodiment of this disclosure, the second request message may include information about at least one core network.

[0081] Step 402: Send the first indication information to the UE via RRC signaling according to the second request message.

[0082] In one embodiment of this disclosure, the first indication information can be used to indicate whether the core network queried by the UE supports sending a paging reason.

[0083] Furthermore, it should be noted that in one embodiment of this disclosure, the access network device can also notify the UE whether the core network it is inquiring about supports sending paging reasons by sending core network information to the UE.

[0084] Specifically, in one embodiment of this disclosure, after receiving the second request message, the access network device can determine whether the core network queried by the UE in the second request message supports sending paging reasons. When the core network queried by the UE supports sending paging reasons, the access network device can also send core network information to the UE via RRC signaling. The core network information may include information about the core network queried by the UE that supports sending paging reasons (e.g., the core network ID), to notify the UE which core networks support sending paging reasons. Furthermore, when the core network queried by the UE does not support sending paging reasons, the access network device may not send information about the core network that does not support sending paging reasons to the UE. Therefore, after sending the second request message, the UE can first determine whether it has received core network information. If it receives core network information within a preset time period, it indicates that the core network included in the core network information supports sending paging reasons; if it does not receive core network information within the preset time period, it indicates that the core network queried does not support sending paging reasons.

[0085] In summary, in the information transmission method provided in this embodiment, the access network device can send first indication information and / or core network information to the UE. The first indication information indicates whether the core network connected to the access network device supports sending paging reasons, and the core network information includes information about the core network that supports sending paging reasons. Therefore, in this embodiment, the UE can obtain information about the core network that supports sending paging reasons. Based on this, when a core network that supports sending paging reasons sends a paging message to a multi-SIM UE, it can simultaneously send the paging reason corresponding to the paging message to the multi-SIM UE. Then, when a paging conflict occurs, the multi-SIM UE can determine the priority of the paging message based on the paging reason, thereby avoiding missing important paging messages and reducing losses.

[0086] Figure 5 This is a flowchart illustrating an information transmission method provided in yet another embodiment of the present disclosure, applied to a core network, such as... Figure 5 As shown, the information transmission method may include the following steps:

[0087] Step 501: Send the second indication information to the UE via NAS (Non-Access Stratum) signaling.

[0088] In one embodiment of this disclosure, a detailed description of the UE is provided in the first embodiment described above, and will not be repeated here.

[0089] Furthermore, in one embodiment of this disclosure, the second indication information can be used to indicate whether the core network supports sending a paging reason. Specifically, in one embodiment of this disclosure, the core network can directly send the second indication information to the UE via NAS signaling through access network equipment or other equipment to notify the UE whether the core network supports sending a paging reason. For ease of description, in the embodiments of this disclosure, sending information from the core network to the UE through access network equipment or other equipment is referred to as core network sending to UE. Similarly, sending information from the UE to the core network through access network equipment or other equipment is also referred to as UE sending to core network.

[0090] In one embodiment of this disclosure, in an NR system, the core network can send a second indication message to the UE via RegistrationAccept signaling.

[0091] Furthermore, in another embodiment of this disclosure, in an LTE system, the core network can send a second indication message to the UE via AttachAccept signaling.

[0092] Furthermore, it should be noted that in one embodiment of this disclosure, the core network can also send core network information to the UE via NAS signaling. The core network information may include information about the core network (such as the core network ID) to notify the UE whether the core network supports sending paging reasons.

[0093] In summary, in the information transmission method provided in this embodiment, the core network can send second indication information to the UE, wherein the second indication information is used to indicate whether the core network supports sending paging reasons. Therefore, in this embodiment, the UE can know whether the core network supports sending paging reasons. Based on this, when a core network supporting paging reasons sends a paging message to a multi-SIM UE, it can simultaneously send the paging reason corresponding to the paging message to the multi-SIM UE. Then, when a paging conflict occurs, the multi-SIM UE can determine the priority of the paging message based on the paging reason, thereby avoiding missing important paging messages and reducing losses.

[0094] Figure 6 This is a flowchart illustrating an information transmission method provided in yet another embodiment of the present disclosure, applied to a core network, such as... Figure 6 As shown, the information transmission method may include the following steps:

[0095] Step 601: Determine the type of UE based on the UE's registration information.

[0096] In one embodiment of this disclosure, the core network can obtain the UE's registration information and determine the UE's type based on the UE's registration information, so that it can subsequently determine whether to send a second instruction message to the UE based on the UE's type. In one embodiment of this disclosure, the UE type may include, for example, single-SIM single-standby, multi-SIM single-standby, multi-SIM multi-standby, multi-SIM single-standby single-pass, multi-SIM multi-band single-pass, multi-SIM multi-band multi-pass, multi-SIM single-standby single-SIM activation, multi-SIM multi-standby multi-SIM activation, etc.

[0097] Step 602: Determine whether to send a second indication message to the UE via NAS signaling based on the UE type.

[0098] In one embodiment of this disclosure, paging conflicts do not occur for UEs with single-SIM single-standby or multi-SIM multi-standby single-SIM activation. Therefore, when the UE type is single-SIM single-standby or multi-SIM multi-standby single-SIM activation, the core network does not need to send second indication information to the UE; when the UE type is multi-SIM multi-standby multi-SIM activation, the core network can send second indication information to the UE.

[0099] The description of the core network sending the second indication information to the UE via NAS signaling can be found in the fifth embodiment above, and will not be repeated here.

[0100] In summary, in the information transmission method provided in this embodiment, the core network can send second indication information to the UE, wherein the second indication information is used to indicate whether the core network supports sending paging reasons. Therefore, in this embodiment, the UE can know whether the core network supports sending paging reasons. Based on this, when a core network supporting paging reasons sends a paging message to a multi-SIM UE, it can simultaneously send the paging reason corresponding to the paging message to the multi-SIM UE. Then, when a paging conflict occurs, the multi-SIM UE can determine the priority of the paging message based on the paging reason, thereby avoiding missing important paging messages and reducing losses.

[0101] Figure 7 This is a flowchart illustrating an information transmission method provided in yet another embodiment of the present disclosure, applied to a core network, such as... Figure 7 As shown, the information transmission method may include the following steps:

[0102] Step 701: Obtain the third request message sent by the UE.

[0103] In one embodiment of this disclosure, a detailed description of the UE is provided in the first embodiment described above, and will not be repeated here.

[0104] Step 702: Send the second instruction information to the UE via NAS signaling according to the third request message.

[0105] For a detailed description of how the core network sends the second indication information to the UE via NAS signaling, please refer to the fifth embodiment above. This embodiment will not be repeated here.

[0106] In summary, in the information transmission method provided in this embodiment, the core network can send second indication information to the UE, wherein the second indication information is used to indicate whether the core network supports sending paging reasons. Therefore, in this embodiment, the UE can know whether the core network supports sending paging reasons. Based on this, when a core network supporting paging reasons sends a paging message to a multi-SIM UE, it can simultaneously send the paging reason corresponding to the paging message to the multi-SIM UE. Then, when a paging conflict occurs, the multi-SIM UE can determine the priority of the paging message based on the paging reason, thereby avoiding missing important paging messages and reducing losses.

[0107] Figure 8 This is a flowchart illustrating an information transmission method provided in yet another embodiment of the present disclosure, applied to a UE, such as... Figure 8 As shown, the information transmission method may include the following steps:

[0108] Step 801: Receive information, which may include at least one of the following: first indication information sent by the access network device, core network information sent by the access network device, and second indication information sent by the core network.

[0109] In one embodiment of this disclosure, detailed descriptions of the first instruction information, core network information, and second instruction information can be found in any of the above embodiments, and will not be repeated here.

[0110] Furthermore, in one embodiment of this disclosure, the information received in step 801 may only include the first instruction information.

[0111] Furthermore, in one embodiment of this disclosure, when the information only includes the first indication information, the method can be as follows: Figure 9 The following are included:

[0112] Step 901: Receive the first indication information sent by the access network device through system messages.

[0113] That is, in one embodiment of this disclosure, the UE can directly receive the first indication information sent by the access network device through system messages.

[0114] Furthermore, in one embodiment of this disclosure, system messages may include MSI and OSI.

[0115] In one embodiment of this disclosure, when the system message is MSI, the UE can directly receive the first indication information sent by the access network device through the MSI.

[0116] In one embodiment of this disclosure, when the system message is OSI, the UE can directly receive the first indication information sent by the access network device through OSI. In another embodiment of this disclosure, when the system message is OSI, the UE can receive the first indication information sent by the access network device through OSI based on the first request message by sending a first request message to the access network device.
