[0080] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings. The method, device and communication equipment for determining the leaving mode provided in the embodiments of the present application are not limited to the Long Term Evolution (LTE) / LTE evolution (LTE-Advanced, LTE-A) system, and can also be used for other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA) and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used for the above-mentioned systems and radio technologies as well as for other systems and radio technologies. However, the following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following description, although these techniques may also be applied to applications other than NR system applications, such as a 6th Generation (6G) communication system.

[0081] In order to facilitate a better understanding of the embodiments of the present application, the following technical points are first introduced below.

[0082] A multi-card terminal (also called a multi-card UE) is a device with two or more user identity modules (SIM) cards. The SIM card is an electronic SIM card or a physical SIM card. From the perspective of the network, the same terminal device and different SIM cards constitute different UEs. In addition, a multi-card terminal can also be called a multiple universal subscriber identity module (MUSIM) terminal.

[0083] Optionally, the SIM cards in the multi-card terminal may belong to the same operator or different operators. The wireless communication networks accessed by different SIM cards may be the same or different.

[0084] Optionally, the SIM card may include one of the following: a SIM card, a Universal Subscriber Identity Module (USIM) card, or an Embedded-SIM (eSIM) card. The SIM card may also be named in other ways, such as directly being called a "card", which is not limited in this application.

[0085] In the MUSIM scenario, when the terminal is in a connected state in the second network, the terminal may need to go to the first network to receive paging; or when the terminal needs to send data to the first network, such as IP Multimedia Subsystem (IMS) periodic report, Tracking Area Update (TAU), or other data, the terminal needs to leave the second network and go to the first network; or the paging reason is indicated in the paging, and the terminal goes to the first network according to the paging reason.

[0086] Scenario 1: For a multi-card UE, when the UE is in a connected state in the second network, the UE may request to leave the first network because it wants to go to the first network for business or to send and receive data. The reason why the UE goes to the first network may be: 1) receiving a possible paging from the first network; 2) or the UE needs to send data to the first network, such as IMS periodic report, location update request, or sending data; 3) or the UE receives a paging message from the first network. The message indicates the paging reason, and the UE decides to leave the second network and go to the first network based on the paging reason.

[0087] When the UE leaves the second network by disconnecting from the second network and entering an idle state, if the UE is in the first network for a short time and then quickly returns to the second network, it is necessary to re-establish the connection between the UE and the second network. Frequent release and establishment of connections will cause more signaling overhead.

[0088] For a short-term leaving mode of the second network, the UE and the second network may remain in a connected state but suspend data transmission, which can greatly reduce the signaling overhead caused by connection release and establishment.

[0089] Problem 1: The UE currently does not know how long the service or data of the UE in the first network will take, and how the UE decides when to leave the second network. The second network also does not know whether to set the UE to a short-term or long-term absence when the UE requests to leave.

[0090] Question 2: Generally speaking, when the second network supports the UE to request to leave, long-term leave can be the default supported leave mode, but the UE is unclear whether the second network supports short-term leave. For the second network that does not support short-term leave, the UE may not provide auxiliary information of the leave time.

[0091] Scenario 2: When the UE requests to leave, it can request to leave the RAN network element of the second network through RRC signaling, or it can request to leave the CN network element of the second network through NAS signaling. However, the UE does not know the leaving method supported by the second network.

[0092] Question 3: When the UE requests to leave, it is not clear whether it uses the RRC method or the NAS method to request to leave.

[0093] One solution is that the terminal determines the leaving mode according to the type of the currently accessed radio access technology (Radio Access Type, RAT) and the leaving mode supported by the second network.

[0094] In one implementation, a RAT can only support at most one leaving method. For example, Evolved-UMTS Terrestrial Radio Access (EUTRA) supports NAS leaving method, and NR supports RRC leaving method: 1) If the currently accessed RAT is EUTRA, the UE can use NAS leaving method to request leaving; 2) If the currently accessed RAT is NR, the UE can use RRC leaving method to request leaving.

[0095] In one implementation, a RAT can support at most two leaving modes. For example, if NR supports both RRC and NAS modes for leaving, the RRC mode is regarded as a short-term leaving mode, and the NAS mode is regarded as a long-term leaving mode. The solution is similar to Problem 1 in Scenario 1.

[0096] In the embodiment of the present application, the terminal may leave the second network by requesting a short-term departure or a long-term departure. For a short-term departure, the departure time may be negotiated, and during the departure, the terminal is in a connected state; for a long-term departure of the terminal, the terminal may be put into a non-connected state (such as a non-connected state in an RRC state), such as releasing the terminal to enter an idle state (such as an RRC idle state or a CM idle state) or setting the terminal to an RRC inactive state (RRC_Inactive). In the RRC inactive state, the CM is in a connected state.

[0097] In an optional embodiment of the present application, the leave request initiated through RRC signaling can be used for at least one of the following: requesting a short-term leave mode, requesting a long-term leave mode, being configured to enter a short-term leave mode after initiating a leave request, requesting a long-term leave mode, and being configured to enter a long-term leave mode after initiating a leave request.

[0098] In an optional embodiment of the present application, the leave request initiated through NAS signaling can be used for at least one of the following: requesting a long-term leave mode, and being configured to enter the long-term leave mode after initiating the leave request.

[0099] Data volume In the embodiments of the present application, service type information and service type information can be used interchangeably to represent the same meaning.

[0100] In an optional embodiment of the present application, the data volume includes the cache data volume. For example:

[0101] The data volume of the first network uplink service includes the cached data volume of the first network service in the terminal;

[0102] The data volume of the first network uplink data includes the cache data volume of the first network data in the terminal;

[0103] The data volume of the first network downlink service includes the cached data volume of the first network service in the first network;

[0104] The data volume of the first network downlink data includes the buffered data volume of the first network data in the first network.

[0105] In an optional embodiment of the present application, the type information may be reflected as a paging reason.

[0106] In an optional embodiment of the present application, the type information includes but is not limited to at least one of the following: IMS voice service, location service (LCS), text message, control plane signaling (such as CN location update), IMS signaling (such as IMS periodic report), paging reception, RAN notification, rejection response to paging (such as busy indication), IPv6 broadcast, etc.

[0107] In an optional embodiment of the present application, the data type information includes but is not limited to at least one of the following: control plane signaling (such as NAS signaling), user plane data, and the service type to which the data belongs. The control plane signaling may include but is not limited to at least one of the following: CN location update.

[0108] In an optional embodiment of the present application, the time may include: duration. The departure time may include: departure duration. The required time includes required duration.

[0109] In an optional embodiment of the present application, the leaving mode (such as a leaving mode for leaving the second network, a requested leaving mode, a configured leaving mode, etc.) includes at least one of the following:

[0110] A Leave Request initiated by RRC signaling or a Leave Request initiated by NAS signaling;

[0111] Short-term departure method or long-term departure method;

[0112] in,

[0113] The short-term leaving mode includes a leaving mode of maintaining a connection state and / or suspending data transmission;

[0114] The long-term leaving mode includes a leaving mode of entering a non-connected state.

[0115] In an optional embodiment of the present application, the time required for the first network data and / or the first network service includes the time required for the first network data and the first network service. 1) In one embodiment, the first network data and the first network service are executed concurrently, and the time required for the first network data and the first network service may be less than the sum of the time required for the first network data and the time required for the first network service; or, it may be the maximum time required for the first network data and the time required for the first network service. When there are multiple first network services and / or multiple types of first network data, the time required for the first network service may be the maximum value of the required time for the multiple first network services and the required time for the multiple types of first network data. 2) In another embodiment, when the first network data and the first network service are not executed concurrently but in relay, the time required for the first network data and the first network service may be equal to the sum of the required time for the first network data and the required time for the first network service.

Similarly, the first network uplink service, the first network downlink service, the first network uplink data, and / or the first network downlink data may be executed concurrently.

[0226] In one implementation manner, the above acquisition from the terminal may be generated by the terminal, or acquired from an AS or NAS upper layer of the terminal, or may be pre-configured by the terminal, etc.

[0227] Optionally, the leaving method (including the leaving method of leaving the second network) includes at least one of the following:

[0228] A Leave Request initiated by RRC signaling or a Leave Request initiated by NAS signaling;

[0229] Short-term departure method or long-term departure method;

[0230] in,

[0231] The short-term leaving mode includes a leaving mode of maintaining a connection state and / or suspending data transmission;

[0232] The long-term leaving mode includes a leaving mode of entering a non-connected state;

[0233] In one implementation, the leave request initiated through RRC signaling may include a leave request initiated to a RAN network element; and the leave request initiated through NAS signaling may include a leave request initiated to a CN network element.

[0234] In one implementation, the non-connected state may include at least one of the following: an idle state and an inactive state.

[0235] In one implementation, leaving the second network in a short-term leaving manner may be that the terminal continues to maintain a protection connection state with the second network and maintains a data transmission suspension state with the second network.

[0236] In one implementation, leaving the second network in a long-term leaving manner may be that the terminal enters a non-connected state in the second network.

[0237] In an implementation manner, the above-mentioned leaving manner may include a manner of leaving the second network, and may also include a determined leaving manner, etc.

[0238] Optionally, in the case where the leaving mode includes the short-term leaving mode, the leaving auxiliary information includes the requested leaving time;

[0239] and / or

[0240] In a case where the departure mode includes the long-term departure mode, the departure assistance information does not include the requested departure time.

[0241] In one implementation, if it is determined that the departure is a short-term departure mode, the departure time is carried in the departure auxiliary information to determine the specific short-term departure time. The short-term departure time can also be understood as the time to keep the terminal in a connected state. When the time is exceeded, the network can set the terminal to a non-connected state, such as an idle state.

[0242] In one implementation, if it is determined that the user is away for a long time, the time of leaving may not be carried. It is not difficult to understand that, since the user needs to enter a disconnected state after leaving for a long time, a signaling for establishing a connection is required when the user returns; therefore, the requested time of leaving may not be required. It is not difficult to understand that, therefore, the time of leaving for a long time may not be fixed.

[0243] Optionally, when the first condition is met, determining to initiate a leave request through RRC signaling;

[0244] The first condition includes at least one of the following: the RAT type of the second network currently accessed by the terminal is the new air interface NR, the second network is the fifth-generation mobile communication network system 5GS or a network version evolved than 5GS, the second network supports a leave request initiated by RRC signaling or the second network supports the terminal to request to leave;

[0245] and / or

[0246] When the second condition is met, it is determined to initiate a leave request through NAS signaling; the second condition includes at least one of the following: the RAT type of the second network currently accessed by the terminal is the Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network EUTRA, the second network is the Evolved Packet System EPS, the second network supports the leave request initiated through NAS signaling or the second network supports the terminal request to leave.

[0247] In one implementation, EUTRA may include eLTE, where the eLTE may be an LTE whose radio access network type is LTE but whose connected core network is 5GC.

[0248] Optionally, when the third condition is met, determining a short-term leaving mode and / or initiating a leaving request through RRC signaling; the third condition includes at least one of the following:

[0249] The second network supports short-term departure mode;

[0250] The time required for the service and / or data that triggers the leave request does not exceed the short-term leave time limit;

[0251] The short-term leave time limit can satisfy the sending and / or receiving of the data volume of the service and / or data that triggers the leave request;

[0252] The short-term leave time limit can satisfy the time required for the service and / or data that triggers the leave request;

[0253] and / or

[0254] When the fourth condition is met, determining the long-term leaving mode and / or initiating a leaving request through NAS signaling; the fourth condition includes at least one of the following:

[0255] The second network supports the long-term departure method;

[0256] The inability to determine the time required for the service and / or data that triggers the departure request;

[0257] The departure time from the second network cannot be determined;

[0258] If the third condition is not met,

[0259] The time required for the service and / or data that triggers the leave request exceeds the short-term leave time limit;

[0260] The short-term leave time limit cannot meet the sending and / or receiving of the data volume of the service and / or data that triggers the leave request;

[0261] The short-term leave time cap cannot satisfy the time required for the service and / or data that triggers the leave request.

[0262] In one implementation, some services or data cannot determine or estimate the specific required time, such as telephone calls. In this case, a long-term absence mode can be requested.

[0263] In one implementation, the leave request initiated through NAS signaling may only be used in a long-term leave mode, that is, the terminal initiates a leave request through NAS signaling, and the network sets the terminal in a long-term leave mode.

[0264] In one implementation, initiating a leave request through RRC signaling may be used in a long-term leave mode or a short-term leave mode. That is, the terminal initiates a leave request through RRC signaling, and the network may set the terminal to a short-term leave mode or a long-term leave mode. It is not difficult to understand that when the terminal meets the conditions of the short-term leave mode, the leave request may be initiated through RRC signaling.

[0265] In one implementation mode, a short-term leave time limit may be configured on the first communication device, or the second network may send a short-term leave time limit supported by the second network to the terminal, or the short-term leave time limit may be predefined by the protocol. Thus, when the time required for the first network service or the time required for sending and / or receiving data on the first network exceeds the short-term leave time limit, a long-term leave mode is initiated, otherwise a short-term leave mode may be initiated.

[0266] In one implementation, the first communication device may determine departure auxiliary information, such as a requested departure time, based on the first information, and send the information to the second network, so that the second network determines whether the departure is short-term or long-term.

[0267] As an optional implementation manner, when the NAS of the first communication device determines the leaving mode of leaving the second network, the first operation further includes at least one of the following:

[0268] The AS of the first communication device sends the first information acquired from the first network to the NAS of the first communication device or the NAS of the first communication device acquires the first information from the first network;

[0269] The NAS of the first communication device determines a leaving mode and / or leaving auxiliary information for leaving the second network according to the first information obtained from the AS, the NAS upper layer and / or the first network;

[0274] The AS of the first communication device determines a leaving method and / or leaving auxiliary information for leaving the second network according to the first information acquired from the NAS and / or the first network.

[0275] In one implementation, the first information obtained from the first network and the first information obtained from the terminal are different. Of course, it is not excluded that they may be the same.

[0276] In one implementation, the first communication device NAS may confirm the leaving method. For example, when the AS receives a paging and the paging (belonging to an RRC message) contains the first information, the AS sends the first information to the NAS; or when the first network notification message carries the first information (belonging to a NAS message), the NAS of the first communication device receives the first information; in addition, the NAS may also obtain the first information from the upper layer of the terminal at the same time. It is not difficult to understand that the NAS may determine the leaving method and / or the leaving auxiliary information for leaving the second network based on the first information obtained from the terminal and / or the first network.

[0277] In another implementation, the AS layer of the first communication device may confirm the leaving method. For example, when the NAS obtains the first information from the upper layer of the terminal, and / or the NAS obtains the first information sent by the first network from the notification message; the NAS sends the first information to the AS of the terminal. It is not difficult to understand that the AS can determine the leaving method and / or the leaving auxiliary information of leaving the second network based on the first information obtained from the terminal and / or the first network.

[0278] Optionally, when it is determined that a leave request is initiated through RRC signaling, the first operation further includes at least one of the following:

[0281] The AS of the first communication device initiates a leave request and / or leaves the auxiliary information through RRC signaling;

[0282] or

[0283] When it is determined that the leave request is initiated through NAS signaling, the first operation further includes at least one of the following:

[0284] The AS of the first communication device sends the first information and / or the departure auxiliary information to the NAS of the first communication device;

[0285] The NAS of the first communication device receives the departure assistance information from the AS of the first communication device, or the NAS of the first communication device determines the departure assistance information according to the first information obtained from the NAS and / or the first network;

[0286] The NAS of the first communication device initiates a leave request and / or leaves the auxiliary information through NAS signaling.

[0287] In one implementation, the first communication device AS may determine the leaving auxiliary information, and the AS may initiate a leaving request and / or the leaving auxiliary information through RRC signaling.

[0288] In another implementation, the first communication device NAS may determine the leaving assistance information, and the AS may initiate a leaving request and / or leaving assistance information through RRC signaling.

[0289] Optionally, the sending the leaving assistance information to the second network includes:

[0290] A leave request is sent to the second network, where the leave request includes the leave assistance information.

[0291] In one implementation manner, the leaving auxiliary information may be sent through a leaving request, so that the communication device of the second network determines the leaving mode and / or leaving time of the terminal leaving the second network according to the leaving auxiliary information.

[0292] Optionally, the obtaining of the first information includes at least one of the following:

[0293] receiving the first information from a first network;

[0294] Acquire the first information from the terminal (such as from a NAS of the terminal or from a UI interface between the terminal and the user);

[0296] The first communication device AS receives the first information from the NAS of the first communication device;

[0297] The first communication device NAS receives the first information from the AS of the first communication device.

[0298] In one implementation, when the first information is obtained from a terminal, the first network service in the first information is a first network uplink service; and the first network data in the first information is a first network uplink data.

[0458] The following example illustrates the method for determining the leaving mode provided in the embodiment of the present application:

[0459] See also Figure 6-1 ,like Figure 6-2 As shown, the following steps are included:

[0460] Step 01: A RAN network element receives data about a terminal (such as NAS signaling of a control plane and / or user plane data). Optionally, based on the information about a first network service and / or data of the terminal, first information is confirmed, specifically, Figure 3 As described in the embodiments.

[0461] The first network RAN ​​sends a paging message to the terminal, where the paging message carries first information.

[0462] According to the first information obtained in step 01, the terminal itself also generates services and / or data that need to be sent to the first network. The terminal determines the leaving method and / or the leaving time of the second network according to the first information of the first network and its own first information, as shown in the following example. Figure 2 As described in the embodiments,

[0463] Step 02: The terminal sends a message related to a request to leave to the second network RAN ​​or CN. The message may include auxiliary information for requesting to leave, such as Figure 2 described.

[0469] Step 01b: AMF receives a service request about the terminal and / or generates data about the first network of the terminal (such as control plane data)

[0470] The AMF may determine the first information according to information about the first network service and / or data of the terminal, such as Figure 3 As described in the embodiments.

[0471] The AMF may trigger a paging message or a notification message, as described in steps 02a and 02b.

[0472] Step 02a. AMF sends a paging message to the RAN network element, where the paging message includes the first information.

[0473] The first network RAN ​​sends a paging message to the terminal, where the paging message carries first information.

[0474] Step 02b: AMF sends a notification message to the terminal, where the notification message includes the first information. AMF may send the notification message to the terminal via non-3GPP.

[0475] According to the first information obtained in step 02, the terminal itself also generates services and / or data that need to be sent to the first network. The terminal determines the leaving method and / or the leaving time of the second network according to the first information of the first network and its own first information, as shown in the following example.
