[0066] Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, which include various details of the embodiments of the present disclosure to help in understanding, which should be considered in their context only. Thus, those of ordinary skill in the art will recognize various changes and modifications of the embodiments described herein, without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and structures are omitted in the following description for clarity and conciseness.

[0067] 5G mobile communication technology has been widely used in commercial applications, and has been widely deployed. The deployment of 5G technology can provide eMBB, mMTC, URLLC and other three major features for terminal devices. When a conventional 5G base station searches for a called terminal device in an idle state, i.e., a target terminal device, it will broadcast the paging according to the registration information of the terminal device, so all terminal devices in the cell will receive the paging. In the conventional paging reception scheme, only the target terminal device will respond to the paging, while other non-target terminal devices in the same cell will ignore the paging and consider it as a garbage paging for non-target terminal devices. The mechanism of only the target terminal device responding and the complex wireless transmission environment greatly increase the possibility that the paging is not responded by the target terminal device.

[0068] With the rapid development of intelligent terminal devices, terminal devices supporting dual SIM cards have become a trend. In the dual card mode, due to the limitation of the antenna, when one card is in the connected state, the other card in the idle state may not be able to receive the paging sent by the base station in time, resulting in the phenomenon of missed paging, so that the card in the idle state cannot respond to the base station in time, causing problems such as the inability to successfully establish a call and other services. In addition, when the primary card is performing data services, the secondary card continuously receives garbage paging, which will also affect the performance of the primary card data service to some extent. In order to solve this problem, the existing paging scheme based on discontinuous reception (DRX) is used, in which the secondary card is periodically woken up to receive paging. However, this still has problems. If the DRX period is set too short, it will cause the battery to be consumed too quickly; if the DRX period is set too long, it will cause the phenomenon of missed paging.

[0069] Currently, existing commercial networks already support eMBB scenarios, thereby providing users with greater bandwidth and faster speeds. With the freezing of 3GPP Release 16 and Release 17, support for mMTC and URLLC scenarios will gradually be increased, providing large-scale device access capabilities and ultra-low latency connections as low as 5ms. It is precisely the large-scale device access and ultra-low latency characteristics that provide the capability support for the present scheme.

[0070] Figure 7 is a related paging reception scheme diagram provided according to an embodiment of the present disclosure. As shown in Figure 7 In the related art, the two SIM cards in one dual card terminal device belong to the same operator and are camped in the same cell. When one card listens to paging, it receives the paging of the other card, and directly wakes up the called SIM card in the idle state through the paging sharing page sharing scheme, so that the called SIM card starts to change from the idle state to the connected state to perform services.

[0071] However, the above method is only applicable to the scenario where the two SIM cards in the same terminal device belong to the same base station and the SIM cards belong to the same operator. The conditions are relatively harsh, and the universality is poor.

[0072] Figure 1 is a method flow diagram of paging reception provided according to an embodiment of the present disclosure. As shown in Figure 1 The paging reception method includes:

[0073] Step 101, determine the card state of the SIM card in the target terminal device, and determine the paging reception strategy according to the card state.

[0074] In this embodiment, the SIM card list is dynamically changing, and changes in the card status of the SIM cards in the target terminal device affect the registration status in the SIM card list. TelephonyManager is a service class that manages mobile phone call status and telephone network information. This class provides numerous getXxx() methods to obtain relevant information about the terminal device. After determining the card status of the SIM cards using the getSimState() method, the target terminal device determines the paging reception strategy based on the SIM card status. It is understood that if the SIM card status is different, the target terminal device's paging information reception strategy will also be different. The SIM card status includes at least a connected state and an idle state.

[0075] Step 102: Receive paging information according to the paging reception strategy.

[0076] Once the paging reception strategy is determined, it can be executed to receive the paging information.

[0077] This embodiment of the disclosure determines the paging reception strategy by the card status of the SIM card in the target terminal device. Based on the reception strategy and the search paging information, the probability of the target SIM card in the target terminal device missing paging information is reduced, the paging information reception rate of the target terminal device is improved, and the power consumption of the target terminal device is reduced.

[0078] Optionally, the target terminal device includes at least a first SIM card and a second SIM card, and the step of determining the paging reception strategy based on the card status of the SIM cards in the target terminal device includes:

[0079] If both the first SIM card and the second SIM card are in an idle state, a discontinuous reception strategy is adopted.

[0080] In this embodiment of the disclosure, if both the first SIM card and the second SIM card are in an idle state, then the card information of the first SIM card and the second SIM card will not exist in the SIM card list in the server terminal, and the target terminal device will use the discontinuous reception DRX strategy to receive paging information.

[0081] In the embodiment of the present disclosure, the first SIM card and the second SIM card are in an idle state, and the card information does not exist in the SIM card list of the server, so that the auxiliary terminal device and the server cannot be used to assist the target terminal device to receive the paging information, and only the DRX strategy can be used to periodically wake up the first SIM card and the second SIM card to enter a connected state, and listen to a broadcast channel to receive the paging information sent by the base station. For example, the wake-up period of the periodically waking up the first SIM card and the second SIM card is T, and the first SIM card is woken up every T to enter the connected state and listen to the broadcast channel, and then enters the idle state; after T, the second SIM card is woken up to enter the connected state, and the cycle is repeated. It should be noted that the first SIM card and the second SIM card cannot enter the connected state at the same time, and the time points of waking up the first SIM card and the second SIM card cannot be at the same time.

[0082] If any one of the first SIM card and the second SIM card is in an idle state, and the other is in a connected state, or the first SIM card and the second SIM card are both in an idle state, and one of the SIM cards is converted from an idle state to a connected state, a multi-terminal device assisted receiving strategy is used.

[0083] In the embodiment of the present disclosure, the multi-terminal device assisted receiving strategy is a strategy for using terminal devices and a server in the same SIM card list to assist the target terminal device to receive the paging information, and the terminal devices other than the target terminal device in the SIM card list are used as auxiliary terminal devices. The auxiliary terminal device listens to the broadcast channel, and if the paging information sent by the base station is received, the paging information is forwarded to the server.

[0084] The server compares the paging information with the card information in the SIM card list, for example, compares the C-RNTI in the paging information and the terminal identification code of the terminal device to which the SIM card belongs with the card information in the SIM card list, to find the target SIM card and the target terminal device of the paging information. The server forwards the paging information to the target SIM card in the target terminal device.

[0085] Optionally, the discontinuous reception paging strategy comprises:

[0086] Periodically wake up the first SIM card and the second SIM card to enter a connected state, and make the first SIM card and the second SIM card listen to a broadcast channel to receive the paging information.

[0087] In the embodiments of the present disclosure, the discontinuous reception paging strategy is a strategy of periodically waking up an idle state SIM card to listen to a broadcast channel. The target terminal device periodically wakes up the first SIM card and the second SIM card to listen to the broadcast channel to receive a paging sent by a base station. The period of waking up the SIM card can be adjusted by an implementer according to actual conditions, and the present disclosure does not limit the specific value of the period.

[0088] Optionally, in the multi-terminal device auxiliary receiving strategy, the paging information is paging information forwarded by the server according to paging information sent by an auxiliary terminal device, or the paging information is paging information sent by a base station.

[0089] In the embodiments of the present disclosure, the multi-terminal device auxiliary receiving strategy is a strategy of using terminal devices in a same SIM card list to assist the target terminal device in receiving paging information. The terminal devices in the SIM card list except the target terminal device are auxiliary terminal devices. The auxiliary terminal devices listen to a broadcast channel. If the paging information is received, the auxiliary terminal devices forward the paging information to the server.

[0090] The server compares the paging information with card information in the SIM card list to determine a target SIM card and a target terminal device corresponding to the paging information. The server further forwards the paging information to the target SIM card in the target terminal device.

[0091] In a possible embodiment, in the multi-terminal device auxiliary receiving strategy, a SIM card in a connected state in the target terminal device listens to a broadcast channel to receive paging information sent by a base station. The SIM card in the connected state analyzes a SIM card identifier in the paging information. If the SIM card identifier matches the first SIM card or the second SIM card in the target terminal device, the target terminal device is paged according to the paging information. If the SIM card identifier does not match the first SIM card or the second SIM card in the target terminal device, the target terminal device sends the paging information to the server. The server finds a terminal device corresponding to the paging information according to a SIM card list and forwards the paging information. Optionally, the target terminal device includes at least the first SIM card and the second SIM card. The paging receiving strategy is determined according to a card state of the SIM card in the target terminal device, and includes:

[0092] If the first SIM card and the second SIM card are both in the idle state, the first registration indication information is sent to the server to delete the card information of the first SIM card and the second SIM card on the SIM card list, wherein the card information at least includes one of a cell radio network temporary identifier (C-RNTI) corresponding to the SIM card and a terminal identification code of a terminal device to which the SIM card belongs. The C-RNTI is used to identify a target SIM card in the terminal device, and each terminal device has a unique terminal identification code, and different terminal devices can be distinguished by the terminal identification code.

[0093] In the embodiments of the present disclosure, the registration indication information needs to be sent to the server to update the card information of the SIM card of the target terminal device in the SIM card list.

[0094] If the SIM card in the target terminal device is registered in the SIM card list, the paging receiving strategy of the target terminal device assisted by the auxiliary terminal device can be used to receive the paging information. If the SIM card in the target terminal device is not registered in the SIM card list, or the SIM card in the target terminal device is unregistered in the SIM card list, the strategy of the target terminal device assisted by the auxiliary terminal device cannot be used to receive the paging.

[0095] In the present disclosure, if the first SIM card and the second SIM card are both in the idle state, the auxiliary terminal device cannot be used to assist the target terminal device to receive the paging information, and the first registration indication information needs to be sent to the server to make the SIM card list not have the card information of the first SIM card and the second SIM card.

[0096] In a possible embodiment, after the server receives the first registration indication information and detects that the SIM card list contains the card information of the first SIM card and the second SIM card, the card information of the first SIM card and the second SIM card on the SIM card list is deleted.

[0097] In a possible embodiment, after the server receives the first registration indication information and the SIM card list does not contain the card information of the first SIM card and the second SIM card, the card information of the first SIM card and the second SIM card is not added to the SIM card list, and at this time, the deletion operation also does not need to be performed.

[0098] If any one of the first SIM card and the second SIM card is in the idle state and the other is in the connected state, or both the first SIM card and the second SIM card are in the idle state and one of the SIM cards is converted from the idle state to the connected state, the second registration indication information is sent to the server to make the SIM card list have the card information of the first SIM card and the second SIM card.

[0099] In the embodiments of the present disclosure, if any one of the first SIM card and the second SIM card is in an idle state, and the other is in a connected state, or both the first SIM card and the second SIM card are in an idle state, and one of the SIM cards is converted from an idle state to a connected state, it indicates that the auxiliary terminal device can be used to assist the target terminal device to receive the paging information. Therefore, the target terminal device sends second registration indication information to the server to add the card information of the first SIM card and the second SIM card in the target terminal device to the SIM card list.

[0100] In a possible embodiment, the server receives the second registration indication information, and the card information of the first SIM card and the second SIM card is not included in the SIM card list. The card information of the first SIM card and the second SIM card is added to the SIM card list.

[0101] In a possible embodiment, the server receives the second registration indication information, and the card information of the first SIM card and the second SIM card is already included in the SIM card list. No change is made to the SIM card list.

[0102] In a possible embodiment, the server receives the second registration indication information, and the card information of the first SIM card is already included in the SIM card list, and the card information of the second SIM card is not included in the SIM card list. The card information of the second SIM card is added to the SIM card list.

[0103] Figure 2 A method flow diagram for receiving paging is provided according to an embodiment of the present disclosure. As shown in Figure 2 The method for receiving paging includes the following steps.

[0104] Step 201, receiving paging information sent by a server according to a SIM card in a connected state;

[0105] In the embodiments of the present disclosure, one of the SIM cards in the target terminal device is in a connected state, and the other is in an idle state. Only the SIM card in the connected state can receive the paging information. In this embodiment, the paging information is received by the SIM card in the connected state.

[0106] Step 202, parsing the paging information according to the SIM card in the connected state to obtain a target SIM card identifier;

[0107] In the embodiments of the present disclosure, the SIM card in the connected state parses the paging information to obtain a target SIM card identifier. According to the target SIM card identifier, it can be determined whether the SIM card in the connected state that receives the paging information is the target SIM card.

[0108] Step 203a, determining a target SIM card according to the target SIM card identifier, and transmitting the paging information to the target SIM card.

[0109] In the embodiments of the present disclosure, if the target SIM card corresponding to the paging information is the connected-state SIM card in the target terminal device, the target terminal device transmits the paging information to the connected-state SIM card, and the connected-state SIM card performs related services according to the paging information.

[0110] In a possible embodiment, if the target SIM card corresponding to the paging information is the idle-state SIM card in the target terminal device, the target terminal device wakes up the target SIM card through the connected-state SIM card, and transmits the paging information to the idle-state SIM card, and the idle-state SIM card can perform related services according to the paging information after entering the connected state.

[0111] In a possible embodiment, the target SIM card is the idle-state SIM card, the idle-state SIM card enters the connected state according to the paging information, and another SIM card in the target terminal device enters the idle state from the connected state.

[0112] Step 203b, if the target SIM card is not the first SIM card or the second SIM card, transmitting the paging information to the server.

[0113] In the embodiments of the present disclosure, if the SIM card identifier does not match the first SIM card or the second SIM card in the target terminal device, the target terminal device transmits the paging information to the server. It can be understood that, at this time, the target terminal device can be used as an auxiliary device of other terminal devices. The server finds the terminal device corresponding to the paging information according to the SIM card list and forwards the paging information.

[0114] Figure 3 FIG. 1 is a flowchart of a method for receiving a page according to an embodiment of the present disclosure. As shown in FIG. 1, the method for receiving a page includes the following steps. Figure 3

[0115] Step 301, when receiving the paging information sent by the auxiliary terminal device, determining a target terminal device according to the paging information and card information in the SIM card list.

[0116] ​In the embodiments of the present disclosure, when the target terminal device adopts the multi-terminal device assisted receiving strategy, the server can serve as an intermediate medium for the transmission of the paging information. The paging information sent by the auxiliary terminal device is received, and the paging information is compared with the card information in the SIM card list to determine the target terminal device corresponding to the paging information, so as to forward the paging information to the target terminal device. Further, the paging information is compared with the card information in the SIM card list to determine the target SIM card of the target terminal device, and then the paging information is forwarded to the target SIM card in the target terminal device. It can be understood that the C-RNTI for determining the target SIM card and the terminal identification code for determining the target terminal device are carried in the paging information.

[0117] In step 302, the paging information is sent to the target terminal device, wherein the paging receiving strategy determined by the card state of the SIM card of the target terminal device is the multi-terminal device assisted receiving strategy.

[0118] In the embodiments of the present disclosure, the target terminal device is a device for receiving the paging message sent by the base station, the auxiliary terminal device is a device corresponding to the base station and not receiving the paging message, and the target terminal device and the auxiliary terminal device are located within the signal transmission range of the same base station. The auxiliary terminal device is used to listen to the broadcast channel, and if the auxiliary terminal device listens to the paging information sent by the base station from the broadcast channel, the paging information is sent to the server. The server finds the target terminal device from the SIM card list according to the information sent by the auxiliary terminal device, and sends the paging information to the target terminal device.

[0119] The embodiments of the present disclosure forward the paging information through the terminal device in the SIM card list to assist the target terminal device in receiving the paging information, reduce the probability of missing the paging information by the SIM card in the target terminal device, improve the receiving rate of the target terminal device in receiving the paging information, and reduce the energy consumption of the target terminal device.

[0120] Optionally, the method further comprises: receiving the registration indication information sent by the terminal device, and updating the SIM card list according to the card state of the SIM card in the registration indication information.

[0121] In the embodiments of the present disclosure, a Subscriber Identity Module (SIM) card is an Integrated Circuit Card (IC) card held by a mobile user of a Global System for Mobile Communications (GSM) system, and is referred to as a user identification card. The GSM system identifies a GSM user through the SIM card. The same SIM card can be used on different terminal devices. The terminal device can be used only after the SIM card is inserted.

[0122] The SIM card is a key for the terminal device to connect to the GSM network. Once the SIM card is removed from the mobile phone, the mobile phone cannot enjoy various services provided by the network operator except for emergency calls. In addition to serving as a key, the SIM card also provides many services for the user. The user can communicate only by inserting or embedding the SIM card into any terminal device. The SIM card also manages information of many services provided to the user, and can be used to store short messages.

[0123] In order to improve the probability that a target SIM card in a target terminal device in a cell corresponding to a base station receives a page, the present disclosure utilizes a plurality of terminal devices to assist each other in receiving paging information, utilizes the characteristic that one base station simultaneously connects a plurality of terminal devices, establishes a server including a plurality of SIM card lists, and one SIM card list corresponds to one base station. Card information of the SIM card in the plurality of terminal devices camping on the same base station is saved in the SIM card list. When the SIM card is registered for the first time, the card information corresponding to the SIM card is uploaded to the server, and the SIM card list is generated. The SIM card list is a dynamic table, and dynamically changes according to the card state change of the SIM card in the terminal device camping on the base station. Specifically, the SIM card list is dynamically updated according to the card state of the SIM card in the registration indication information sent by the terminal device. The card information includes a Cell-Radio Network Temporary Identifier (C-RNTI) corresponding to the SIM card and a device identification code of the terminal device to which the SIM card belongs.

[0124] Optionally, the terminal device includes at least a first SIM card and a second SIM card, and the updating of the SIM card list according to the registration indication information includes:

[0125] If the first registration indication information is received, and the card information of the first SIM card and the second SIM card is included in the SIM card list, the card information of the first SIM card and the second SIM card in the SIM card list is deleted.

[0126] In the embodiments of the present disclosure, if the server receives the first registration indication information sent by the terminal device, it is indicated that the first SIM card and the second SIM card on the terminal device are both in the idle state, and the target terminal device cannot receive the paging information with the assistance of the auxiliary terminal device. If the first SIM card and / or the second SIM card are already included in the SIM card list, the card information of the first SIM card and the second SIM card is deleted in the SIM card list.

[0127] If the first registration indication information is received, and the card information of the first SIM card and / or the second SIM card is not included in the SIM card list, the card information of the first SIM card and the second SIM card is not added in the SIM card list.

[0128] In the embodiments of the present disclosure, if the server receives the first registration indication information sent by the terminal device, it is indicated that the first SIM card and the second SIM card on the terminal device are both in the idle state, and the target terminal device cannot receive the paging information with the assistance of the auxiliary terminal device. If the first SIM card and the second SIM card are not included in the SIM card list, the card information of the first SIM card and the second SIM card is not added in the SIM card list.

[0129] If the second registration indication information is received, and the card information of the first SIM card and the second SIM card is not included in the SIM card list, the card information of the first SIM card and the second SIM card is added in the SIM card list, wherein the card information includes the C-RNTI corresponding to the SIM card and the terminal identification code of the terminal device to which the SIM card belongs.

[0130] In the embodiments of the present disclosure, if the server receives the second registration indication information sent by the terminal device, it is indicated that any one of the first SIM card and the second SIM card on the terminal device is in the idle state, and the other is in the connected state, or both the first SIM card and the second SIM card are in the idle state, and one of the SIM cards is converted from the idle state to the connected state. The target terminal device can receive the paging information with the assistance of the auxiliary terminal device. The card information of the first SIM card and the second SIM card needs to be added in the SIM card list. The card information includes the C-RNTI corresponding to the SIM card and the terminal identification code of the terminal device to which the SIM card belongs. The C-RNTI is used to distinguish the first SIM card and the second SIM card belonging to the same terminal device, and the terminal identification code is used to distinguish the terminal device to which the SIM card belongs.

[0131] Figure 8 is a schematic diagram of a paging receiving scheme according to the embodiments of the present disclosure. As shown in Figure 8As shown, for a mobile phone (terminal device) residing in a 5G base station, a list of SIM cards corresponding to the 5G base station is created in a server, and the server determines whether two SIM cards in the mobile phone meet the registration conditions, i.e., one is in an idle state and the other is in a connected state.

[0132] If the SIM cards in the mobile phone meet the registration conditions, the identity information (C-RNTI, mobile identification number) of the SIM cards in the mobile phone is registered in the list of SIM cards, the idle state SIM card stops listening to the paging information of the base station broadcast channel, and other mobile phones residing in the same base station simultaneously listen to the broadcast channel, and upload the paging information listened to to the server. The paging information is parsed by other mobile phones and transmitted to the server, and the server determines the SIM card and mobile phone corresponding to the paging according to the previously registered information, i.e., the card information in the list of SIM cards, and transmits the data (i.e., the paging information) to the mobile phone corresponding to the paging information.

[0133] If the SIM cards in the mobile phone do not meet the registration conditions, the SIM cards in the mobile phone do not need to be registered in the list of SIM cards in the server, if the SIM cards in the mobile phone have been registered in the list of SIM cards, the SIM cards in the mobile phone are unregistered, and if the SIM cards in the mobile phone have not been registered in the list of SIM cards, no registration is performed. The mobile phone uses a discontinuous reception (DRX) scheme to receive the paging sent by the base station.

[0134] Figure 9 According to an embodiment of the present disclosure, an auxiliary terminal device paging schematic diagram is provided. As shown in Figure 9 In this scenario, a server is established by utilizing the characteristic that one base station is connected to multiple UEs (terminal devices) at the same time. Multiple UEs residing in the same base station upload the C-RNTI allocated by the base station to the server during the first registration, and jointly maintain and update the dynamic table of the list of SIM cards. If the UE is a dual card, two C-RNTIs of two SIM cards will be registered at the same time, and they are marked as the same UE. When receiving the paging of other UEs, the paging and the list of SIM cards are matched. If the called user UE corresponding to the C-RNTI is matched, the paging is uploaded to the server. The server sends the paging to the SIM card in the connected state corresponding to the called user UE. The idle state SIM card is awakened via the SIM card in the connected state to perform business.

[0135] Registering the UE in the SIM card list in the server can make the other card in the idle state completely stop receiving the paging, thereby saving the precious battery energy. The UE registered in the server coordinates the state, and each time multiple registered other UEs simultaneously listen to the broadcast channel and transmit the listened information to the server. Then, the paging is transmitted back to the called user UE corresponding to the paging by the SIM card in the connected state using the C-RNTI in the server. After the called user UE receives the data, the parsed data is transmitted internally to the card in the idle state.

[0136] Through the scheme, the problem of missing paging in the main card connected state and the secondary card idle state can be solved. In addition, through repeated listening to the paging by multiple UEs, repeated reception can be realized, and the scheme of paging sharing can be realized, thereby greatly reducing the probability of missing paging. Moreover, the SIM card in the idle state completely stops listening to the broadcast channel, and the energy consumption can be greatly saved.

[0137] Figure 10 A dynamic registration diagram of a terminal device is provided according to an embodiment of the present disclosure. As shown in Figure 10 When the UE (terminal device) is inserted with double SIM cards, there are two common states: both SIM cards are in the idle state; one SIM card is in the connected state, and the other SIM card is in the idle state. When both SIM cards are in the idle state, the server is logged out, that is, registered, and the DRX is set to receive the paging according to the conventional protocol.

[0138] When one SIM card is in the connected state and the other SIM card is in the idle state, the two SIM cards are registered in the server using the C-RNTI allocated by the base station.

[0139] When one SIM card is in the connected state and the other SIM card is in the idle state, the two SIM cards are registered in the server using the C-RNTI allocated by the base station.

[0140] Therefore, the UE registered in the server needs at least one card in the connected state, and other states are logged out.

[0141] Since the server side always maintains a dynamic table SIM card list, the state of the user can be fed back in real time, and the user is registered or logged out in the server according to the state.

[0142] In a possible embodiment, when the state of the UE changes from camping on a base station to leaving the base station, the SIM card in the UE is logged out in the SIM card list. The reasons for the change of the camping state of the UE include that the UE leaves the communication range of the base station and the UE is powered off.
