[0021] FIG. 1 shows a block diagram of a wireless communication system to which the embodiments of the present application can be applied. The wireless communication system includes a terminal 11 and a network side device 12. The terminal 11 may be called a terminal device or a user equipment (UE), and may be a terminal side device such as a mobile phone, a tablet personal computer (Tablet Personal Computer), a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (Mobile Internet Device (MID)), a wearable device, a vehicle user equipment (VUE), a pedestrian terminal (PUE), etc., and wearable devices include a bracelet, an earphone, glasses, etc. Note that the embodiments of the present application are not limited to a specific type of the terminal 11.

[0022] In an embodiment of the present application, if the first network may not be able to provide normal service in the event of some disaster event (e.g., fire, earthquake, tsunami, etc.), the terminal attempts to access another network that supports that access, and this function is called the Minimization of Service Interruption (MINT) function, and this disaster event is called the Disaster event corresponding to MINT.

[0023] When an event corresponding to the MINT function occurs, if the UE attempts to access a second network to obtain a service, the terminal executing the MINT function determines the access identity and / or access category corresponding to this access, and / or the MINT access control information sent from the network, and performs access control.

[0024] Terminal action: In the terminal, the first parameter indicates an access identity corresponding to the MINT function, and is stored, for example, in a Universal Subscriber Identity Module (USIM) or a non-volatile memory of the terminal. The terminal checks whether it can access the second network based on one or more of the setting of the MINT function by the terminal, the access identity corresponding to the MINT function, the access category, and the MINT access control information of the second network.

[0025] Actions of network side equipment: The network side equipment can send access control information corresponding to the MINT function to the terminal, such as the access category defined by the operator that corresponds to the access attempt when executing the MINT function, the access probability to be executed for this access category, and the waiting time of the UE before retrying if access is prohibited by the MINT function.

[0026] Hereinafter, with reference to the drawings, the method, device, equipment and readable storage medium for a terminal to access a network provided in the embodiments of the present application will be described in detail through specific embodiments and application scenarios.

[0027] Referring to FIG. 2, an embodiment of the present application provides a method for a terminal to access a network, which can be performed by a terminal, and specifically includes step 201.

[0028] Step 201: When an event corresponding to a MINT function (for example, a disaster event such as a fire, earthquake, tsunami, etc.) occurs in a first network, access control is performed on an access request to a second network triggered by the MINT function.

[0029] In an embodiment of the present application, after step 201, the method further includes a step of sending the access request to the second network if the second network allows the terminal to access, or a step of retrying access to the second network if the second network currently does not allow the terminal to access.

[0030] Optionally, the step of retrying access to the second network includes the steps of determining access restriction conditions based on access control information of the second network, starting a timer according to the access restriction conditions, and retrying access to the second network after the timer times out.

[0031] In an embodiment of the present application, when an event corresponding to the MINT function occurs in the first network, the terminal determines whether the second network should allow access, thus avoiding congestion in the second network caused by a large number of terminals simultaneously attempting to access the second network.

[0032] Referring to FIG. 3, an embodiment of the present application provides a method for a terminal to access a network, which can be performed by a terminal, and specifically includes step 301.

[0033] Step 301: When an event corresponding to a MINT function occurs in a first network, based on first information, determine whether the second network will allow an access request to the second network triggered by the MINT function of the terminal.

[0034] The first information is (1) Settings related to the MINT functions of the terminal, such as access identifiers, access categories, etc.; (2) Access control information regarding the MINT function of the second network.

[0035] In some embodiments of the present application, in step 301, based on an access identifier corresponding to the MINT function selected by the terminal and an access identifier corresponding to the received MINT function of the second network, the second network determines whether to allow an access request to the second network triggered by the MINT function of the terminal.

[0036] Optionally, before step 301, the method further includes the steps of determining whether the second network supports MINT functionality, and if the second network supports MINT functionality, selecting an access identifier corresponding to the MINT functionality indicated by the second network (indicated in a broadcast manner) when attempting to access the second network.

[0037] Optionally, the step of determining whether the second network supports MINT functionality includes the steps of: obtaining a list of capabilities supported by the second network; and determining whether the second network supports MINT functionality based on the list of capabilities supported by the second network.

[0038] Optionally, a Universal Subscriber Identity Module (USIM) or non-volatile memory of the terminal stores a first parameter indicating an access identifier corresponding to the MINT function.

[0039] In some other embodiments of the present application, in step 301, the second network determines whether to allow an access request to the second network triggered by the MINT function of the terminal based on an access category corresponding to the MINT function selected by the terminal and an access category corresponding to the MINT function of the second network.

[0040] Optionally, before step 301, the method may further include the step of obtaining an access category corresponding to a MINT function defined by an operator via the first network or the second network.

[0041] Optionally, before step 301, the method further comprises: The method further includes receiving access control information related to MINT functionality of the second network.

[0042] Optionally, said access control information comprises one or more of the following:

[0043] (1) An access identity corresponding to a MINT function of the second network.

[0044] (2) an access category corresponding to the MINT function of the second network;

[0045] (3) An access probability corresponding to the access category and / or access identifier.

[0046] Illustratively, the network broadcasts an access probability corresponding to the access category of MINT, e.g., 0.9, and the terminal locally generates a random number ranging from 0 to 1; if the random number is smaller than 0.9, the terminal is allowed to initiate access; otherwise, the terminal is temporarily not allowed to initiate access.

[0047] It can be understood that the embodiment of the present application does not limit the specific value of the access probability.

[0048] (4) A first type of access request that is not prohibited and is triggered by a MINT function.

[0049] It may be further limited as being triggered when a MINT function triggers access to any particular network.

[0050] (5) A second type of access request that is not prohibited and is triggered by a user of some specific network (e.g., the first network) through a MINT function. For example, the second network can indicate by broadcast information that a terminal of some network (e.g., the first network) can access the second network.

[0051] (6) A delayed third type access request, which is triggered by a MINT function or by a user of a particular network (e.g., the first network) by a MINT function.

[0052] (7) Access delay time.

[0053] In an embodiment of the present application, after step 301, the method further includes a step of sending the access request to the second network if the second network allows the terminal to access, or a step of retrying access to the second network if the second network currently does not allow the terminal to access.

[0054] Optionally, the step of retrying access to the second network includes the steps of determining access restriction conditions based on access control information of the second network, starting a timer according to the access restriction conditions, and retrying access to the second network after the timer times out.

[0055] In an embodiment of the present application, when the first network may be unable to provide normal services in the event of some disaster event (e.g., fire, earthquake, tsunami, etc.), when the terminal attempts to access the second network that supports such access, the second network determines whether to allow the terminal to access based on the terminal's settings related to the MINT function and / or the access control information related to the MINT function of the second network, thereby increasing the probability of the terminal accessing the second network via the MINT function and improving the utilization efficiency of network access resources in the event of a MINT-related event.

[0056] Referring to FIG. 4, an embodiment of the present application provides a method for a terminal to access a network, which is performed by a network-side device and specifically includes step 401.

[0057] Step 401: Send access control information related to the MINT function of the second network to the terminal.

[0058] The access control information regarding the MINT function of the second network and / or the settings regarding the MINT function of the terminal are intended to assist the terminal in access control of access requests to the second network triggered by the MINT function when an event corresponding to the MINT function occurs in the first network.

[0059] Optionally, said access control information comprises: (1) an access identifier corresponding to a MINT function of the second network; and (2) an access category corresponding to the MINT function of the second network; (3) an access probability corresponding to the access category and / or access identifier; and (4) a first type of access request that is not prohibited and is triggered by a MINT function; and (5) a second type of access request that is not prohibited and is triggered by a user of a specific network (e.g., the first network) through a MINT function; (6) a delayed third-type access request, the third-type access request being triggered by a MINT function or by a user of a particular network (e.g., the first network) by a MINT function; (7) Access delay time.

[0060] In an embodiment of the present application, the network side device transmits access control information related to the MINT function of the second network to the terminal, and when the first network is likely to be unable to provide normal service when some disaster event occurs, when the terminal attempts to access the second network that supports its access, the second network determines whether to allow the terminal to access based on the setting related to the MINT function of the terminal and / or the access control information related to the MINT function of the second network, thereby increasing the probability of the terminal accessing the second network via the MINT function and improving the utilization efficiency of network access resources when an event related to MINT occurs.

[0061] Examples 1 to 5 of the present invention will be described below.

[0062] Example 1 - Access identity configuration information corresponding to the MINT function is added to the USIM.

[0063] 5a and 5b, the file EFUAC_AIC of the USIM may be added with access identity configuration information for the MINT function by the terminal. In the UAC access identities configuration, the access identity information (e.g., whether it is valid and / or its value) corresponding to the MINT function is indicated by the value of one or more bits.

[0064] Example 2 - Access identity corresponding to MINT functionality.

[0065] When an event corresponding to the MINT function occurs, the terminal expects that when attempting to access the second network to obtain a service, the UE executing the MINT function will select the access identity to be used during the access attempt.

[0066] It can be understood that the process of selecting the access identity to be used during this access attempt may also be related to whether the second network supports MINT functionality, for example, an access identity corresponding to the MINT functionality may be selected only if the second network supports MINT functionality, and this access identity may further be notified to the access stratum.

[0067] [Table 1]

[0068] The UE may determine whether to select an access identity corresponding to the MINT function when attempting to access the second network based on whether the second network supports the MINT function, for example, by reading a list of features supported by the second network (e.g., a 5GS network feature support IE) from the signaling of the second network.

[0069] If the second network does not support the MINT function, the access identity corresponding to the MINT function is not selected when attempting to access the second network.

[0070] If the second network supports the MINT function, an access identity corresponding to the MINT function is selected when attempting to access the second network.

[0071] The access control check process for access identity can be seen in the following example:

[0072] (1) After the UE running the MINT function selects an access identity, it attempts to initiate a registration request which triggers an access request.

[0073] (2) The terminal checks the access identity corresponding to the terminal executing the MINT function of the second network broadcast, and if it determines that access is permitted, it starts the access. If it determines that the access of this access identity is restricted by a certain condition (e.g., probability), it calculates the access condition (e.g., probability). If the condition calculation results in a need to delay access, it starts a timer and attempts access after the timeout. If the condition calculation results in access being permitted, it starts the access.

[0074] The signaling of the second network carries information indicating that the second network supports the MINT feature, such as a 5GS network feature support IE (see "MINT" in Figure 6). For example, whether the second network supports the MINT feature is indicated by one bit (see Figure 7).

[0075] Example 3 - Standard access categories corresponding to MINT functions.

[0076] The access categories corresponding to the MINT functions may include standard access categories, ie, access categories standardized in each network, and access categories defined by the operator.

[0077] The terminal specifies an access category corresponding to MINT based on the standard access category and the access category defined by the operator, and performs an access barring check using this access category.

[0078] If there are other access reasons other than the access attempt triggered by the MINT function, such as an emergency call, the terminal considers various access reasons, selects the access category with the highest probability of allowing the terminal access, and performs an access barring check.

[0079] The network can transmit parameter information such as access category, access identity, access probability indication information, calculated delay time, etc. (see Table 2) corresponding to the access request for the MINT function to the terminal via air interface signaling.

[0080] [Table 2]

[0081] The following is an example of the access control check process for the access category:

[0082] (1) A UE performing MINT functionality selects an access category and then attempts to initiate a registration request, which triggers an access request. (2) The terminal checks the access category corresponding to the UE executing the MINT function of the second network broadcast, and if it confirms that access is permitted, it starts the access. If it confirms that access of this access category is restricted by certain conditions (e.g., probability), it calculates the access conditions (e.g., probability). If it is necessary to delay the access as a result of the condition calculation, it starts a timer and attempts access after the timeout. If it is permitted as a result of the condition calculation, it starts the access.

[0083] Example 4 - The network advertises MINT access categories defined by the operator.

[0084] The network may transmit an access category corresponding to an access request for MINT functionality defined by the operator to the terminal via air interface signaling. For example, The first network transmits the access category of the first network itself and / or another network (e.g., the second network) to the terminal by signaling, or The second network transmits the access category of the second network itself and / or another network (for example, the first network) to the terminal by signaling.

[0085] When a terminal attempts to access a network using MINT functions, if the operator of the network has defined an access category that the terminal should adopt when attempting access using MINT functions, then the terminal will attempt to access the network using that access category.

[0086] For example, the network can indicate the operator-defined access category of the MINT in an operator-defined access category definitions information element (see Figure 8).

[0087] Referring to Figures 9 and 10, this operator-defined access category definitions IE can be sent to the terminal in the NAS air interface message CONFIGURATION UPDATE COMMAND and the registration result (success, failure) message.

[0088] Example 5 - Process of access barring check corresponding to MINT function.

[0089] Referring to FIG. 11, specifically, the process includes steps 1101 to 1107.

[0090] Step 1101: When an event corresponding to a MINT function occurs in a first network, a UE decides to attempt to access a second network.

[0091] Step 1102: The second network, based on information such as load, subscription, etc., indicates in its air interface information access control information related to the MINT function, such as not prohibiting access requests triggered by the MINT function, or not prohibiting access requests triggered by the MINT function by users of some specific network (e.g., some dedicated network, Public Land Mobile Network (PLMN) in a specific country code), or determines whether and how to delay the access request triggered by the UE by the MINT function, for example, calculating the delay time, based on the current load, etc.

[0092] Step 1103: The UE receives access control information for the MINT of the second network, for example, UAC information for the MINT of the second network broadcast.

[0093] Step 1104: When the UE performing the MINT function attempts to access the second network, it selects a corresponding access identity and / or access category.

[0094] Step 1105: The UE checks whether access is possible based on the access identity, and / or access category, and / or access control information for the MINT sent from the network air interface, and if possible, executes step 1106; if not, executes step 1107.

[0095] Step 1106: Send an access request.

[0096] Step 1107: A timer is started, and access is retried after a timeout.
