[0027] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. For the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] Before introducing the technical solution of this application, the following will explain the relevant knowledge involved in the technical solution of this application:

[0029] Radio Resource Control (RRC) status in New Radio (NR):

[0030] It should be understood that in the embodiment of the present application, NR can also be deployed independently. In order to reduce air interface signaling and quickly restore wireless connections and data services in the 5G network environment, a new RRC state is defined, namely, the RRC inactive (RRC_INACTIVE) state. This state is different from the RRC idle (RRC_IDLE) state and the RRC connected (RRC_CONNECTED) state.

[0031] In the RRC_IDLE state: mobility is based on the cell selection reselection of the terminal device, paging is initiated by the core network (CN), and the paging area is configured by the CN. There is no terminal device access stratum (AS) context on the base station side, and there is no RRC connection.

[0032] In the RRC_CONNECTED state: an RRC connection exists, and a terminal device AS context exists between the base station and the terminal device. The base station knows the location of the terminal device at the specific cell level. The mobility is the mobility controlled by the base station. Unicast data can be transmitted between the terminal device and the base station.

[0033] In the RRC_INACTIVE state: mobility is based on the cell selection reselection of the terminal device, there is a connection between CN-NR, the AS context of the terminal device exists on a base station, paging is triggered by the Radio Access Network (RAN), and the RAN-based paging area is managed by the RAN. The base station knows the location of the terminal device based on the RAN paging area level.

[0034] It should be noted that in the embodiments of the present application, the RRC non-activated state may also be referred to as the RRC deactivated state, and the present application does not limit this.

[0035] The base station can control the state transition of the terminal device, for example Figure 1 As shown, a terminal device in an RRC connected state can enter an RRC idle state by releasing the RRC connection; a terminal device in an RRC idle state can enter an RRC connected state by establishing an RRC connection; a terminal device in an RRC connected state can enter an RRC inactive state by suspending (Release with Suspend) the RRC connection; a terminal device in an RRC inactive state can enter an RRC connected state by resuming (Resume) the RRC connection, and can also enter an RRC idle state by releasing the RRC connection.

[0036] It should be noted that the terminal device is in the RRC inactive state. The terminal device automatically returns to the RRC idle state in the following situations:

[0037] 1. When receiving the initial paging message from CN;

[0038] 2. When initiating an RRC recovery request, start timer T319. If the timer times out;

[0039] 3. When the integrity protection verification of contention-based random access message 4 (Message 4, MSG4) fails;

[0040] 4. When the cell reselects to another radio access technology (Radio Access Technology, RAT);

[0041] 5. Enter the camp on any cell state.

[0042] Characteristics of RRC inactive state:

[0043] 1. The connection between RAN and CN is maintained;

[0044] 2. The terminal device and at least one base station save the AS context;

[0045] 3. The terminal device is reachable to the RAN side, and the relevant parameters are configured by the RAN;

[0046] 4. When the terminal device moves within the RAN Notification area (RNA) configured by the RAN, it does not need to notify the network side (core network equipment), but when it moves out of the RNA, it needs to notify the network side (core network equipment);

[0047] 5. The terminal device moves within the RNA according to the cell selection and reselection method.

[0048] It should be noted that RNA can be specifically Figure 2 As shown, in Figure 2 In the RNA shown, the terminal device does not need to notify the network side when it moves between base station 1 and base station 5, but needs to notify the network side when the terminal device moves to base station 6 or base station 7.

[0049] The terminal device performs cell reselection in the RRC idle state and the RRC inactive state. In the process of cell selection and reselection performed by the terminal device in the RRC idle state, in order to meet the load balancing in idle state, a cell reselection strategy based on frequency priority is defined. In the reselection of cells with the same frequency or different frequencies with the same frequency priority, the R criterion is used to reselect cells, that is, the cells are sorted according to their signal quality, and the cell with the best signal quality is selected as the candidate reselection target cell. For cells with high frequency priority, as long as the cell signal quality meets a certain threshold, they will be reselected to cells with high frequency priority. For cells with low frequency priority, they will be reselected only when the signal quality of the serving cell is lower than a certain threshold.

[0050] Optionally, the technical solution of the present application can be applied to dual-card business scenarios, for example: Figure 3 As shown, the terminal device is in an RRC inactive state in the network corresponding to the first SIM card, and is in an RRC connected state in the network corresponding to the second SIM card.

[0051] It is worth mentioning that dual-card business scenarios are not limited to Figure 3 The scenario shown, for example: the terminal device can also be in the RRC idle state in the network corresponding to the first SIM card, and in the RRC connected state in the network corresponding to the second SIM card.

[0052] Optionally, the first SIM card and the second SIM card may be two SIM cards of the same network standard, for example, they are both SIM cards of the Global System of Mobile communication (GSM) network, or they are both SIM cards of the Code Division Multiple Access (CDMA) network, or they are both SIM cards of the NR network, etc. Of course, the first SIM card and the second SIM card may also be two SIM cards of different network standards, for example, one of the two SIM cards resides in a Long Term Evolution (LTE) cell, and the other SIM card resides in a NR cell.

[0053] It should be noted that the first SIM card and the second SIM card can be SIM cards provided by the same operator or provided by different operators, and this application does not impose any restriction on this.

[0054] In summary, for any SIM card in the first SIM card and the second SIM card, they can correspond to various communication systems, such as: GSM system, CDMA system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), LTE system, Advanced long term evolution (LTE-A) system, NR system, NR system evolution system, LTE on unlicensed spectrum (LTE-based access to unlicensed spectrum, LTE-U) system, non-terrestrial communication network (NTN) system, NR on unlicensed spectrum (NR-based access to unlicensed spectrum, NR-U) system, Universal Mobile Telecommunication System (UMTS), next generation communication system or other communication systems, etc.

[0055] Optionally, the communication system in the embodiment of the present application can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, or a standalone (SA) networking scenario.

[0056] The embodiments of the present application do not limit the spectrum to which they are applied. For example, the embodiments of the present application can be applied to licensed spectrum or unlicensed spectrum.

[0057] It should be understood that a device having a communication function in a network / system in the embodiments of the present application may be referred to as a communication device.

[0058] In the embodiment of the present application, the terminal device may also be referred to as user equipment, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device, etc. The terminal device may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, and a next generation communication system, for example, a terminal device in an NR network or a terminal device in a future evolved Public Land Mobile Network (PLMN) network, etc.

[0059] As an example but not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-sized, and fully or partially independent of smartphones, such as smart watches or smart glasses, as well as devices that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets and smart jewelry for vital sign monitoring.

[0060] The present application relates to a network device corresponding to a first SIM card (i.e., a first network device). The first network device may be a base station (Base Transceiver Station, BTS) in GSM or CDMA, or a base station (NodeB, NB) in WCDMA, or an evolved base station (Evolutional NodeB, eNB or eNodeB) in LTE, or a relay station or access point, or a vehicle-mounted device, a wearable device, and a network device (gNB) in an NR network, or a network device in a future evolved PLMN network, or a network device in an NTN network, etc.

[0061] In an embodiment of the present application, the first network device provides services for a cell, and the terminal device communicates with the first network device through the transmission resources used by the cell (for example, frequency domain resources, or spectrum resources). The cell may be a cell corresponding to the first network device (for example, a base station), and the cell may belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0062] The present application also relates to a second network device, which is responsible for the mobility management function in the core network. For example, the second network device may be an access and mobility management function (AMF) entity.

[0063] As described above, for a dual-SIM dual-standby terminal, if the terminal is performing services through one SIM card, and the network device corresponding to the other SIM card sends a paging message, that is, the terminal device is in an RRC inactive state or an RRC idle state under the network corresponding to the first SIM card, and is in an RRC connected state under the network corresponding to the second SIM card. In this case, how to securely obtain the paging cause is a technical problem to be solved in this application.

[0064] In order to solve the above technical problems, in the present application, the paging message carries the index of the paging reason. The terminal device determines the paging reason through the correspondence between the index of at least one paging reason and the at least one paging reason, as well as the index carried in the paging message, so as to safely obtain the paging reason.

[0065] The technical solution of this application will be described in detail below:

[0066] Figure 4 An interactive flow chart of a wireless communication method provided in an embodiment of the present application, such as Figure 4 As shown, the method comprises the following steps:

[0067] S410: The first network device sends a paging message to the terminal device, where the paging message includes: an index of a first paging reason.

[0068] S420: The terminal device determines the first paging reason according to the correspondence between the index of at least one paging reason and the at least one paging reason, and the index of the first paging reason.

[0069] It should be understood that the first network device is a network device corresponding to the first SIM card.

[0070] It should be understood that any paging reason is used to indicate the service type of the paging message that triggers the paging reason, for example, the service type may be voice type, video type or game type.

[0071] It should be understood that the correspondence between the index of at least one paging reason and the at least one paging reason is a one-to-one correspondence. The index of at least one paging reason includes: the index of the first paging reason. The at least one paging reason includes: the first paging reason.

[0072] Exemplarily, Table 1 shows the correspondence between the index of at least one paging reason and at least one paging reason:

[0073] Table 1

[0074]

[0075] Optionally, the correspondence between the index of at least one paging reason and at least one paging reason may be predefined or preconfigured, and this application does not impose any limitation on this.

[0076] It should be understood that in the dual-SIM dual-standby scenario, the terminal device is registered with both the network corresponding to the first SIM card and the network corresponding to the second SIM card. The network corresponding to the first SIM card and the network corresponding to the second SIM card can be the same or different, for example: Figure 3 What is shown is the situation that the network corresponding to the first SIM card and the network corresponding to the second SIM card are different.

[0077] Optionally, the second network device may obtain a correspondence between an index of at least one paging reason and at least one paging reason according to the capability information of the terminal device, and send the correspondence to the terminal device, specifically to a non-access stratum (NAS) of the terminal device.

[0078] Optionally, when the network corresponding to the first SIM card and the network corresponding to the second SIM card are the same, the second network device may be an AMF entity in the network. When the network corresponding to the first SIM card and the network corresponding to the second SIM card are different, the second network device may be an AMF entity in the network corresponding to the first SIM card, or an AMF entity in the network corresponding to the second SIM card.

[0079] Optionally, the capability information of the terminal device is used to indicate that the terminal device supports dual-card services and / or that the terminal device supports a paging reason function.

[0080] It should be understood that the dual-card service is also described as a dual-card dual-standby service, a multi-card service, a dual-card or a multi-card, etc., and this application does not impose any limitation on this.

[0081] It should be understood that the terminal device supporting the paging reason function means that the terminal device can determine the paging reason according to the index of the paging reason and the correspondence between the index of at least one paging reason and at least one paging reason.

[0082] In summary, in the present application, the paging message carries the index of the paging reason. The terminal device determines the paging reason through the correspondence between the index of at least one paging reason and the at least one paging reason, as well as the index carried in the paging message. Therefore, there is no need to transmit the paging reason, thus avoiding the transmission risk of the paging reason, and thus ensuring that the terminal device can safely obtain the paging reason.

[0083] It should be understood that the terminal device obtains the index of the first paging reason in the access layer, and as described above, the non-access layer obtains the corresponding relationship between the index of at least one paging reason and at least one paging reason. In this case, the terminal device can determine the first paging reason in any of the following ways:

[0084] Implementation method 1: The terminal device sends the index of the first paging reason to the non-access layer through the access layer; the terminal device determines the first paging reason at the non-access layer based on the correspondence between the index of at least one paging reason and at least one paging reason, as well as the index of the first paging reason.

[0085] Possible implementation method 2: The terminal device receives the correspondence between the index of at least one paging cause and at least one paging cause from the non-access layer at the access layer. Based on this, the terminal device can determine the first paging cause at the access layer according to the correspondence between the index of at least one paging cause and at least one paging cause, as well as the index of the first paging cause.

[0086] Optionally, in the case of the above-mentioned implementation method 1, if the first paging cause is used to indicate that the service type that triggers the paging message meets the preset condition, the terminal device sends a notification message to the access layer through the non-access layer. The notification message is used to notify the access layer to initiate an RRC connection establishment process or an RRC connection recovery process to the first network device corresponding to the first SIM card. The terminal device initiates an RRC connection establishment process or an RRC connection recovery process to the first network device corresponding to the first SIM card at the access layer according to the notification message.

[0087] Optionally, in the case of the above-mentioned implementation method 2, if the first paging reason is used to indicate that the service type triggering the paging message meets a preset condition, the terminal device initiates an RRC connection establishment process or an RRC connection recovery process to the first network device corresponding to the first SIM card.

[0088] It should be understood that if the terminal device is in an RRC idle state under the network corresponding to the first SIM card, the terminal device initiates an RRC connection establishment process to the first network device corresponding to the first SIM card, so that the terminal device can send and receive service data under the network corresponding to the first SIM card. If the terminal device is in an RRC inactive state under the network corresponding to the first SIM card, the terminal device initiates an RRC connection recovery process to the first network device corresponding to the first SIM card, so that the terminal device can send and receive service data under the network corresponding to the first SIM card.

[0089] Optionally, the preset condition includes any of the following, but is not limited to:

[0090] The service type that triggers the paging message is voice type.

[0091] The service type that triggers the paging message is a video type.

[0092] The service type that triggers the paging message is the game type.

[0093] The service type that triggers the paging message is a high priority service type.

[0094] Optionally, the high priority service type may be predefined, which is not limited in the present application.

[0095] In summary, in the present application, the terminal device can determine the first paging reason at the access layer or non-access layer based on the obtained index of the first paging reason and the above-mentioned correspondence, thereby eliminating the need to transmit the paging reason, avoiding the transmission risk of the paging reason, and thereby ensuring that the terminal device can safely obtain the paging reason.
