Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden for the embodiments herein, are intended to be within the scope of the present application.

Before introducing the technical scheme of the application, the following will explain related knowledge related to the technical scheme of the application:

radio resource control (Radio Resource Control, RRC) state in New air interface (New Radio, NR):

it should be understood that in the embodiment of the present application, NR may be deployed independently, and a new RRC state, namely an RRC INACTIVE (rrc_inactive) state, is defined in the 5G network environment for the purposes of reducing air interface signaling and quickly recovering wireless connection, and quickly recovering data traffic. This state is different from the RRC IDLE (rrc_idle) state and the RRC CONNECTED (rrc_connected) state.

In rrc_idle state: mobility is cell selection reselection based on terminal equipment, paging is initiated by a Core Network (CN), and paging areas are configured by the CN. The base station side does not have an Access Stratum (AS) context of the terminal equipment, and does not have RRC connection.

In the rrc_connected state: there is an RRC connection and the base station and the terminal device have a terminal device AS context. The base station knows that the location of the terminal device is cell specific. Mobility is base station controlled mobility. Unicast data may be transmitted between the terminal device and the base station.

Rrc_inactive state: mobility is cell selection reselection based on terminal equipment, there is a connection between CN-NRs, the terminal equipment AS context is present on a certain base station, paging is triggered by the radio access network (Radio Access Network, RAN), the RAN-based paging area is managed by the RAN, the base station knows that the location of the terminal equipment is based on the RAN paging area level.

In the embodiment of the present application, the RRC inactive state may also be referred to as an RRC inactive state, which is not limited in this application.

The base station may control state transition of the terminal device, for example, as shown in fig. 1, the terminal device in the RRC connected state may enter the RRC idle state by releasing the RRC connection; the terminal equipment in the RRC idle state can enter an RRC connection state by establishing an RRC connection; a terminal device in an RRC connected state may enter an RRC inactive state by suspending release (Release with Suspend) of the RRC connection; the terminal device in the RRC inactive state may enter the RRC connected state by restoring (Resume) the RRC connection, and may also enter the RRC idle state by releasing the RRC connection.

It should be noted that, the terminal device is in an RRC inactive state, and the terminal device autonomously returns to an RRC idle state in the following case:

1. when receiving the paging message initiated by the CN;

2. when an RRC recovery request is initiated, a timer T319 is started, and if the timer times out;

3. when the integrity protection verification of the competition-based random access Message4 (Message 4, MSG 4) fails;

4. upon cell reselection to other radio access technologies (Radio Access Technology, RAT);

5. entering a camp on any cell state.

Characteristics of the RRC inactive state:

1. the connection between RAN and CN is maintained;

2. the terminal equipment and at least one base station store AS context;

3. the terminal equipment is reachable to the RAN side, and related parameters are configured by the RAN;

4. the network side (core network device) need not be notified when the terminal device moves within the RAN notification area (RAN Notification area, RNA) configured by the RAN, but when the RNA is moved out;

5. the terminal device moves within the RNA in accordance with the cell selection reselection mode.

In particular, as shown in fig. 2, in the RNA shown in fig. 2, the terminal device does not need to notify the network side when moving between the base stations 1 to 5, but needs to notify the network side when moving to the base station 6 or the base station 7.

The terminal device performs cell reselection behavior in an RRC idle state and an RRC inactive state. In the process of executing cell selection and reselection in an RRC idle state, the terminal equipment defines a cell reselection strategy based on frequency priority in order to meet the requirement of idle load balancing. And in the cell reselection of the same frequency or different frequency with the same priority, the R criterion is adopted to reselect the cells, namely the cells are ordered according to the signal quality of the cells, and the cell with the best signal quality is selected as a candidate reselection target cell. For cells with high frequency priority, the cell with high frequency priority is reselected as long as the signal quality of the cell meets a certain threshold, and for cells with low frequency priority, the cell with low frequency priority is reselected as long as the signal quality of the serving cell is lower than the certain threshold.

Optionally, the technical solution of the present application may be applied to a dual card service scenario, for example: as shown in fig. 3, the terminal device is in an RRC inactive 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.

It should be noted that the dual card service scenario is not limited to the scenario shown in fig. 3, for example: the terminal device may also be in an RRC idle state in a network corresponding to the first SIM card, and in an RRC connected state in a network corresponding to the second SIM card.

Alternatively, the first SIM card and the second SIM card may be two SIM cards of the same network system, for example: they are all SIM cards of a global system for mobile communications (Global System of Mobile communication, GSM) network, or are all SIM cards of a code division multiple access (Code Division Multiple Access, CDMA) network, or are all SIM cards of an NR network, etc. Of course, the first SIM card and the second SIM card may also be two SIM cards with different network systems, for example: one of the two SIM cards resides in a long term evolution (Long Term Evolution, LTE) cell and the other resides in an NR cell.

It should be noted that, the first SIM card and the second SIM card may be SIM cards provided by the same operator, or may be SIM cards provided by different operators, which is not limited in this application.

By way of example, and not limitation, in embodiments of the present application, the terminal device may also be a wearable device. The wearable device can also be called as a wearable intelligent device, and is a generic name for intelligently designing daily wear by applying wearable technology and developing wearable devices, such as glasses, gloves, watches, clothes, shoes and the like. The wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also can realize a powerful function through software support, data interaction and cloud interaction. The generalized wearable intelligent device includes full functionality, large size, and may not rely on the smart phone to implement complete or partial functionality, such as: smart watches or smart glasses, etc., and focus on only certain types of application functions, and need to be used in combination with other devices, such as smart phones, for example, various smart bracelets, smart jewelry, etc. for physical sign monitoring.

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

The application also relates to a second network device responsible for mobility management functions in the core network, such as: the second network device may be an access and mobility management function (Access and Mobility Management Function, AMF) entity.

As described above, for a dual-card dual-standby terminal, if the terminal is performing a service 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 in an RRC connected state under the network corresponding to the second SIM card. In this case, how to safely acquire the paging cause (paging cause) is a technical problem to be solved urgently by the present application.

In order to solve the above technical problems, in the present application, the paging message carries an index of a paging cause, and the terminal device determines the paging cause by using a correspondence between the index of at least one paging cause and the at least one paging cause, and the index carried in the paging message, so as to safely obtain the paging cause.

The technical scheme of the application will be described in detail as follows:

fig. 4 is an interaction flow chart of a wireless communication method according to an embodiment of the present application, as shown in fig. 4, the method includes the following steps:

s410: the first network device sends a paging message to the terminal device, the paging message comprising: index of the first paging cause.

S420: the terminal equipment determines a first paging cause according to the corresponding relation between the index of at least one paging cause and the index of the first paging cause.

It should be understood that the first network device is the network device to which the first SIM card corresponds.

It should be understood that for any paging cause, it is used to indicate the service type of the paging message that triggered the paging cause corresponds to. For example: the service type may be a voice (voice) type, a video (video) type, or a game (game) type, etc.

It should be understood that the index of at least one paging cause is in a one-to-one correspondence with at least one paging cause. Wherein the index of the at least one paging cause comprises: index of the first paging cause. The at least one paging cause includes: a first paging cause.

Illustratively, table 1 shows the correspondence between the index of at least one paging cause and at least one paging cause:

TABLE 1

Optionally, the correspondence between the index of the at least one paging cause and the at least one paging cause may be predefined or preconfigured, which is not limited in this application.

It should be understood that in the dual-card dual-standby scenario, the terminal device registers in 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 may be the same or different, for example: fig. 3 shows a case where the network corresponding to the first SIM card is different from the network corresponding to the second SIM card.

Optionally, the second network device may obtain a correspondence between the index of the at least one paging cause and the at least one paging cause according to 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.

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 is different from the network corresponding to the second SIM card, 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.

Optionally, the capability information of the terminal device is used to indicate that the terminal device supports the dual card service, and/or the terminal device supports the paging cause function.

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 multi-card service, etc., as the present application is not limited in this regard.

It should be understood that the terminal device supporting the paging cause function means that the terminal device may determine the paging cause according to the index of the paging cause and the correspondence between the index of the at least one paging cause and the at least one paging cause.

In summary, in the present application, the paging message carries an index of a paging cause, and the terminal device determines the paging cause through a corresponding relationship between the index of at least one paging cause and the index carried in the paging message, so that the paging cause does not need to be transmitted, the transmission risk of the paging cause is avoided, and further, the terminal device can safely acquire the paging cause.

It should be understood that the terminal device obtains the index of the first paging cause at the access layer, and as described above, the non-access layer obtains the correspondence between the index of the at least one paging cause and the at least one paging cause. In this case, the terminal device may determine the first paging cause by any one of the following means:

the method can be realized in a first mode: the terminal equipment sends an index of a first paging reason to a non-access layer through an access layer; and the terminal equipment determines a first paging cause according to the corresponding relation between the index of at least one paging cause and the index of the first paging cause in the non-access layer.

The second implementation mode is: the terminal equipment receives the corresponding relation between the index of at least one paging reason and at least one paging reason from the non-access layer at the access layer. Based on this, the terminal device may determine, at the access layer, a first paging cause according to the correspondence between the index of the at least one paging cause and the at least one paging cause, and the index of the first paging cause.

Optionally, in the case of the first implementation manner, if the first paging cause is used to indicate that the service type triggering the paging message meets the preset condition, the terminal device sends the notification message to the access layer through the non-access layer. The notification message is used for notifying 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. And the terminal equipment initiates an RRC connection establishment process or an RRC connection recovery process to the first network equipment corresponding to the first SIM card at the access layer according to the notification message.

Optionally, in the second implementation manner, if the first paging cause is used to indicate that the service type triggering the paging message meets the preset condition, the terminal device initiates an RRC connection establishment procedure or an RRC connection recovery procedure to the first network device corresponding to the first SIM card.

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 procedure to the first network device corresponding to the first SIM card, so that the terminal device receives and transmits service data under the network corresponding to the first SIM card. If the terminal equipment is in an RRC inactive state under the network corresponding to the first SIM card, the terminal equipment initiates an RRC connection recovery process to the first network equipment corresponding to the first SIM card, so that the terminal equipment receives and transmits service data under the network corresponding to the first SIM card.

Optionally, the preset condition includes any one of the following, but is not limited thereto:

the traffic type triggering the paging message is a voice type.

The traffic type triggering the paging message is a video type.

The service type triggering the paging message is a game type.

The traffic type triggering the paging message is a high priority traffic type.

Alternatively, the high priority traffic type may be predefined, which is not limited by the present application.

In summary, in the present application, the terminal device may determine, at the access layer or the non-access layer, the first paging cause according to the obtained index of the first paging cause and the corresponding relationship, so that the paging cause does not need to be transmitted, a transmission risk of the paging cause is avoided, and further it is ensured that the terminal device may safely obtain the paging cause.
