[0126] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0127] FIG1 is a schematic diagram of an application scenario of a network access method provided by an embodiment of the present application. As shown in FIG1 , the scenario includes a terminal side and a network side, the terminal side includes a terminal 100, and the network side includes an access network device 200, and the access network device 200 may be an access and mobility management function network element, a base station, etc. Among them, data is transmitted between the terminal 100 and the access network device 200 through the network.

[0128] The terminal 100 may be a wireless terminal, which may be a device that provides voice and / or other service data connectivity to a user, or a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. The wireless terminal may communicate with one or more core networks via a radio access network (Radio Access Network, referred to as RAN). The wireless terminal may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which exchanges language and / or data with a radio access network. The wireless terminal may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, an access terminal, a user terminal, a user agent, a user device or user equipment, which is not limited here.

[0129] The access network device 200 can be a base station (Base Transceiver Station, BTS) in Global System of Mobilecommunication (GSM) or Code Division Multiple Access (CDMA), or a base station (NodeB, NB) in Wideband Code Division Multiple Access (WCDMA), or an evolved base station (Evolutional Node B, eNB or eNodeB) in LTE, or a relay station or access point, or a base station in a 5G network, etc., and is not limited here.

[0130] It should be noted that the application scenarios of the embodiments of the present application are based on the terminal side and the network side, and are not limited to the network side environment. They can be NB-IoT, as well as massive IoT connection network scenarios under 2G / 3G / 4G / 5G / 6G.

[0131] In the field of communications, a Subscriber Identity Module (SIM) is inserted into mobile phones, wearable devices, and various terminal devices to enable communication between the terminal and the wireless network. In the communication scenario, the terminal device initiates a network access request to the network end, and the network end can choose to accept or reject the access of the terminal device based on the SIM tariff status.

[0132] In the related art, when the network denies access to the terminal device due to the SIM card fee status, such as the SIM card fee is in arrears, suspended, or cancelled, the terminal will still frequently and repeatedly initiate access requests to the mobile network of the same standard that can be found according to the current communication protocol. In the process of the terminal initiating the access request, since the network does not receive the access request of the terminal, a large amount of communication capacity, especially the channel with limited wireless ports, is consumed.

[0133] Based on this, an embodiment of the present application provides a network access method, in which the terminal determines the tariff status of the SIM card carried in the indication message according to the received indication message, and further determines or stops initiating an access request to the network, thereby avoiding the situation where the terminal frequently initiates network access requests when the SIM card tariff status does not support initiating access requests, thereby avoiding occupying a large amount of air interface resources, improving the effectiveness of the terminal initiating access requests, and improving the network air interface quality.

[0134] It should be noted that the beneficial effects brought about by the embodiments of the present application or the technical problems solved are not limited to this one, but may also include other implicit or related problems. For details, please refer to the description of the following embodiments.

[0135] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0136] In one embodiment, as shown in FIG. 2 , a network access method is provided, which is described by taking the method applied to a terminal as an example, and includes the following steps:

[0137] S201, receiving an indication message; the indication message carries the tariff status of the terminal SIM card.

[0138] Among them, the tariff status of the SIM card is used to characterize the actual tariff of the SIM card at the current moment. In the embodiment of the present application, according to the actual tariff situation of the SIM card, the tariff status is divided into two states: normal tariff and arrears. Furthermore, considering that in actual scenarios, the SIM card is allowed to maintain communication with the network side in the case of arrears, such as the arrears time is less than the preset time period, the arrears amount is less than the preset threshold, etc., the arrears status can be further subdivided into: the state where the network can be used due to arrears, the state where the network cannot be used but the network can be accessed due to arrears, the state where the network cannot be accessed due to arrears, the shutdown state, the account cancellation state and other states. Then in one embodiment, the arrears include at least one of the following: the network service can be used due to arrears; the network service cannot be used due to arrears but the network can be accessed; the network cannot be accessed due to arrears; the service is shut down; and the account is cancelled.

[0139] In this embodiment, when the terminal SIM card is in a state of arrears and can use the network, the terminal can communicate with the network normally; when the terminal SIM card is in a state of arrears and cannot use the network but can access the network, the terminal cannot communicate through the network, but can access the network, for example, it can only receive messages sent by the network and cannot send messages through the network; when the terminal SIM card is in any of the states of arrears and cannot access the network, shutdown, or cancellation, the terminal cannot access the network and cannot receive messages sent by the network at all.

[0140] In another scenario, in addition to classifying the tariff status according to the actual tariff of the SIM card, the tariff status can also be divided into a first tariff status that allows access requests to be initiated and a second tariff status that stops access requests from being initiated, according to whether the terminal initiates an access request. Further, the first tariff status includes a normal tariff status, a state where the network can be used due to arrears, a state where the network cannot be used due to arrears but the network can be accessed, and the second tariff status includes a state where the network cannot be accessed due to arrears, a shutdown state, a cancellation state, and the like.

[0141] In the embodiment of the present application, the tariff status of the SIM card is carried in the indication message. When the terminal receives the indication message, it can naturally receive the tariff status of the SIM card carried in the indication message. The embodiment of the present application does not limit the way in which the terminal receives the indication message, that is, the sender of the indication message, including but not limited to Bluetooth mode, base station broadcast mode, SMS mode, etc.

[0142] In a feasible scenario, the indication message may carry the tariff status of the SIM card and may also include an instruction on whether the terminal initiates an access request under the current tariff status of the SIM card, so that the terminal can directly determine whether to initiate an access request to the network according to the instruction in the indication message.

[0143] It should be known that there is only one type of SIM card tariff status, and correspondingly, the content in the indication message is also one of the instructions for initiating access request and the instructions for stopping initiating access request. On this basis, the embodiment of the present application does not limit the content format of the indication message.

[0144] For example, the indication message is text content, and the indication message may include an initiation instruction text for instructing the terminal to initiate an access request to the network; the indication message may include a stop instruction text for instructing the terminal to stop initiating an access request to the network.

[0145] For example, the indication message is in a numerical format, and the indication message may include an initiation instruction value for instructing the terminal to initiate an access request to the network; the indication message may include a stop instruction value for instructing the terminal to stop initiating an access request to the network.

[0146] In actual scenarios, the format of the indication message may be a format corresponding to the actual purpose of the indication message in addition to plain text content and pure numerical content. For example, if the indication message is used to instruct the terminal to initiate an access request, the indication message is the text content; if the indication message is used to instruct the terminal to stop initiating an access request, the indication message is in numerical format.

[0147] In one embodiment, the content of the indication message includes:

[0148] An access indication message corresponding to the tariff status of the SIM card; or an access rejection indication reason value corresponding to the tariff status of the SIM card.

[0149] Among them, the access indication message is in text form, and the tariff status corresponding to the access indication message includes: normal tariff status, network can be used for arrears status, and network cannot be used but access can be obtained for arrears status; the access rejection indication reason value is in numerical format, and the tariff status corresponding to the access rejection indication reason value includes: network cannot be used for arrears status, network cannot be accessed for arrears status, shutdown status, and account cancellation status.

[0150] Of course, in a scenario where the indication message format varies, the indication message can be set to a numerical format when the indication message is used to instruct the terminal to initiate an access request, and can be set to a text format when the indication message is used to instruct the terminal to stop initiating an access request.

[0151] In the embodiment of the present application, considering the terminal behavior, the indication messages corresponding to different terminal behaviors are encapsulated into different formats and sent to the terminal, so that the terminal can quickly distinguish whether to initiate an access request to the network according to the form of the indication message, thereby improving the effectiveness of the terminal initiating an access request to the network. In addition, due to the correspondence between the format of the indication message and the tariff status of the terminal SIM card, the terminal can further clarify the reasons for its own behavior while making the terminal behavior, making the communication between the terminal and the network more transparent and more reliable.

[0152] S202: Determine or stop initiating an access request to the network according to the tariff status of the SIM card in the indication message.

[0153] After reading the tariff status of the SIM card in the indication message, the terminal can determine the target terminal behavior corresponding to the tariff status of the SIM card according to the preset logical relationship between the tariff status and the terminal behavior, and execute the target terminal behavior. Among them, the terminal behavior includes initiating an access request to the network and stopping initiating an access request to the network, and the terminal behavior corresponds to the tariff status one by one.

[0154] Optionally, the terminal can match the tariff status of the SIM card with the tariff status initiation list corresponding to the access request. If the tariff status of the SIM card is in the initiation list, it is determined to initiate an access request to the network; if the tariff status of the SIM card is not in the initiation list, the access request to the network is stopped.

[0155] Optionally, the terminal may also match the tariff status of the SIM card with the tariff status rejection of stopping the access request. If the tariff status of the SIM card is in the rejection list, the access request to the network is stopped; if the tariff status of the SIM card is not in the rejection list, it is determined to initiate an access request to the network.

[0156] Optionally, if the terminal receives an access indication message corresponding to the tariff status of the SIM card, it determines to initiate an access request to the network; if it receives an access rejection indication reason value corresponding to the tariff status of the SIM card, it stops initiating an access request to the network.

[0157] In an embodiment of the present application, the terminal receives an indication message; the indication message carries the tariff status of the terminal SIM card; and according to the tariff status of the SIM card in the indication message, determines or stops initiating an access request to the network. In this method, the terminal obtains the tariff status of the terminal SIM card according to the indication information, and then evaluates whether the terminal can initiate an access request to the network, which is equivalent to comparing the tariff status of the SIM card with the initiation condition of the network access request, and initiating an access request to the network when the tariff status of the SIM card meets the request initiation condition, and stops initiating an access request to the network when the tariff status of the SIM card does not meet the request initiation condition. Such a network access method enables the terminal to perceive the SIM card tariff status in a timely manner, avoiding the situation where the terminal frequently initiates network access requests when the SIM card tariff status does not support the initiation of access requests, thereby avoiding occupying a large amount of air interface resources, improving the effectiveness of the terminal initiating access requests, and improving the network air interface quality.

[0158] The above embodiment does not limit the way in which the terminal receives the indication message, and the indication message may be sent by any sender that has a communication relationship with the terminal.

[0164] In the communication scenario, the terminal can communicate with the access network elements, base stations, SIM card operators, Bluetooth, wireless networks, etc. of the core network, which means that the terminal can receive messages sent by the access network elements, base stations, SIM card operators, Bluetooth, and wireless networks of the core network.

[0165] Taking the communication connection between the terminal and the core network as an example, in this scenario, the indication message is encapsulated in the first signaling interaction information, and the terminal receives the first signaling interaction message sent from the core network to obtain the indication message.

[0179] Take the case where the terminal turns on the Bluetooth function as an example. In this scenario, the indication message is encapsulated in the Bluetooth information. The terminal receives the Bluetooth information sent from the Bluetooth sender and obtains the indication message.

[0180] Taking the terminal turning on the network function as an example, in this scenario, the terminal receives the wireless network push information sent from the wireless network sender and obtains the indication message.

[0181] In an embodiment of the present application, the terminal can receive indication messages sent by different senders in a variety of ways, so as to flexibly determine or stop the terminal action of initiating an access request to the network according to the tariff status of the SIM card carried in the indication message, thereby improving network access efficiency.

[0182] In the 5G communication scenario, the terminal interacts with the AMF network element of the core network, and determines or stops initiating an access request to the AMF network element according to the first signaling interaction information sent by the AMF network element. The following is an example of the terminal behavior in the scenario of interaction between the terminal and the AMF network element.

[0183] In one embodiment, the indication message is the first signaling interaction information sent by the AMF network element; the access request includes a registration request and a service request; and according to the tariff status of the SIM card in the indication message, determining or stopping initiating an access request to the network includes any of the following actions:

[0184] If the SIM card's tariff status is in normal tariff status, a registration request and a service request are sent to the AMF network element;

[0185] If the SIM card's tariff status is in arrears and network services can be used, a registration request and service request are sent to the AMF network element;

[0186] If the SIM card is in arrears and cannot use network services but can access the network, stop sending service requests to the AMF network element;

[0187] If the SIM card is in arrears and cannot access the network, stop sending registration requests to the AMF network element;

[0188] If the SIM card's tariff status is in shutdown state, stop sending registration requests to the AMF network element;

[0189] If the SIM card's tariff status is in the cancelled state, stop sending registration requests to the AMF network element.

[0190] In the interaction scenario between the terminal and the AMF network element, the access request initiated by the terminal to the AMF network element includes a registration request and a service request. Among them, the registration request is sent when the terminal requests to access the core network, and the service request is sent when the terminal requests the core network to provide communication services after accessing the core network.

[0191] After obtaining the tariff status of the SIM card, the terminal performs corresponding terminal actions according to the corresponding relationship between the tariff status and the registration request and service request.

[0192] When the tariff status of the SIM card is in a normal tariff state or a state where network services are available due to arrears, the terminal sends registration requests and service requests to the AMF network element in sequence, requests access to the core network, and establishes a communication connection with the core network; when the tariff status of the SIM card is in a state where network services cannot be used due to arrears but network access is available, the terminal stops sending service requests to the AMF network element, and the terminal can send registration requests to the AMF network element at this time; when the tariff status of the SIM card is in a state where network access is not available due to arrears, or is in a shutdown state, or is in a cancelled account state, the terminal stops sending registration requests to the AMF network element, and will not initiate service requests.

[0193] In the embodiment of the present application, according to the tariff status of the SIM card, the case where the terminal stops initiating access requests is further subdivided into two types: stopping initiating registration requests and stopping initiating service requests but being able to initiate registration requests, so as to more finely adjust the frequency of the terminal initiating access requests and make full use of the network's air interface resources.

[0194] In addition to interacting with the AMF network element, the terminal can also interact with the base station on the network side, and determine or stop initiating an access request to the base station according to the second signaling interaction information sent by the base station. The following describes the terminal behavior in the scenario of terminal-base station interaction through an embodiment.

[0195] In one embodiment, the indication message is second signaling interaction information sent by the base station; the access request includes RCC process information; the RCC process information is any one of an RRC connection establishment request, an RRC reconfiguration request, and an RRC recovery request; and determining or stopping initiating an access request to the network according to the indication message includes any of the following actions:

[0196] If the SIM card's tariff status is in a normal tariff status, an access request is initiated to the base station;

[0197] If the SIM card is in arrears and can use network services, an access request is initiated to the base station;

[0198] If the SIM card is in a state of arrears and cannot use network services but can access the network, then stop initiating access requests to the base station;

[0199] If the SIM card is in arrears and cannot access the network, the access request to the base station is stopped;

[0200] If the SIM card's tariff status is in shutdown state, then stop initiating access requests to the base station;

[0201] If the SIM card's tariff status is in the cancelled state, the access request to the base station will be stopped.

[0202] In the interaction scenario between the terminal and the base station, the access request initiated by the terminal to the base station includes the RRC connection establishment request, the RRC reconfiguration request, and the RRC recovery request. Among them, the RRC connection establishment request is sent by the terminal when the terminal and the base station interact with each other for the first time, the RRC reconfiguration request is sent by the terminal in the scenario where the terminal has an RCC change, and the RRC recovery request is sent by the terminal based on the connection demand after the terminal is disconnected from the RCC.

[0203] After obtaining the tariff status of the SIM card, the terminal determines the terminal behavior corresponding to the RCC process information currently in the terminal according to the tariff status.

[0204] When the tariff status of the SIM card is in a normal tariff state or a state where network services can be used due to arrears, the terminal initiates an access request to the base station, for example, when the RCC process is first established, an RRC connection establishment request is initiated; when the RRC process is changed, an RRC reconfiguration request is initiated; when the RRC is disconnected, an RRC recovery request is initiated; when the tariff status of the SIM card is in a state where network services cannot be used due to arrears but the network can be accessed, or a state where network access cannot be obtained due to arrears, or a shutdown state, or an account cancellation state, the terminal stops sending access requests to the base station.

[0205] In the embodiment of the present application, the terminal behavior is determined according to the tariff status of the SIM card and combined with the RCC process. The entire determination process has clear logic and is suitable for deployment in various communication scenarios between the terminal and the base station to improve the effectiveness of the terminal behavior.

[0206] When a SIM card is inserted into a terminal, the charge status of the SIM card may also change dynamically, for example, the charge for the SIM card is replenished, or the charge of the SIM card decreases during use, etc. Therefore, the terminal needs to adjust its own terminal behavior according to the latest charge status of the SIM card on a regular or real-time basis. The following is an implementation method for dynamically adjusting its own behavior according to the charge status of the SIM card again when the terminal stops initiating an access request to the network, by means of an embodiment.

[0207] In one embodiment, as shown in FIG3 , the method further includes:

[0208] S301, receiving the updated tariff status of the SIM card.

[0209] The updated tariff status of the SIM card is the latest information received by the terminal after receiving the indication message in the above embodiment. The updated tariff status received by the terminal may be sent by the core network, base station, Bluetooth, operator, or wireless network sending end.

[0210] It should be noted that the difference between the updated tariff status and the tariff status carried in the indication message lies in the difference in the terminal receiving time, that is, the terminal receives the updated tariff status later than the indication message, and the updated tariff status information is more effective. Therefore, the sending method and information type of the updated tariff status in the embodiment of the present application can refer to the description in the aforementioned embodiment, and will not be repeated here.

[0211] S302: If the updated tariff status indicates that the SIM card is in an available state, an access request is initiated to the network.

[0212] After determining the update tariff status, it is determined whether the current status of the SIM card is in one of the above available states, and if the current tariff status of the SIM card meets any of the above available states, a corresponding access request is initiated to the network.

[0213] Taking the interaction between the terminal and the AMF network element as an example, in this interaction scenario, the available states include normal tariff state, the state where the network service can be used due to arrears, and the state where the network service cannot be used but the network can be accessed.

[0214] If the updated tariff status is that the SIM card is in a normal tariff state or in arrears and can use network services, a registration request and service request are initiated to the network. If the updated tariff status is that the SIM card is in arrears and cannot use network services but can access the network, a registration request is initiated to the network.

[0215] Taking the interaction between the terminal and the base station as an example, in this interaction scenario, the available status includes the normal tariff status and the network service status that can be used for arrears. If the updated tariff status is that the SIM card is in the normal tariff status or the network service status that can be used for arrears, the RCC process information is initiated to the base station.

[0216] In the embodiment of the present application, taking into account the tariff change factor of the SIM card, the updated tariff status of the SIM card is received, and the behavior of the terminal accessing the network is adjusted in time, and when the updated tariff status of the SIM card is in an available state, an access request is initiated to the network to restore the connection between the terminal and the network and make full use of the network's air interface resources.

[0217] In the following, a possible implementation method of receiving the updated tariff status of the terminal is described. In one embodiment, receiving the updated tariff status of the SIM card includes:

[0218] Receive paging messages based on SIM card charges sent by AMF network elements; the paging messages carry the updated charge status of the SIM card.

[0219] The AMF network element carries the updated tariff status of the SIM card in a paging message and sends it to the terminal. At this time, after receiving the paging message, the terminal parses the paging message and obtains the updated tariff status of the SIM card.

[0220] In an embodiment of the present application, the updated tariff status of the SIM card is carried in the paging message based on the SIM card tariff. In this way, when the terminal receives the paging message from the AMF network element based on the SIM card resources, it can also promptly learn about the updated tariff status of the SIM card, so as to make full use of the interactive signaling between the AMF network element and the terminal and improve the communication efficiency between the two.

[0221] In one embodiment, the method further comprises:

[0222] When the terminal is powered on or off or restarted or the SIM card is reinserted, the tariff status of the SIM card is saved.

[0223] The terminal continuously monitors its own power status and SIM card status to sense in real time whether the terminal is powered on or off, and whether the SIM card is plugged in or out. Furthermore, when it is detected that the terminal is powered off or the SIM card is plugged in and out again, the latest tariff status of the SIM card is saved, so that when the terminal is restarted or the SIM card is inserted into the terminal again, the terminal can make corresponding terminal actions according to the saved tariff status of the SIM card.

[0224] In an embodiment of the present application, when the terminal is monitored to be turned on or off or restarted, or the SIM card is reinserted, the tariff status of the SIM card is saved, thereby avoiding the need to re-receive the tariff status of the SIM card each time the terminal is turned on or the SIM card is inserted. This facilitates the rapid acquisition of the tariff status and the rapid determination of the terminal behavior after the terminal is started or the SIM card is inserted, thereby avoiding waste of air interface resources.

[0225] The above is a description of the relevant embodiments with the terminal as the execution subject. On this basis, the embodiments of the present application also provide embodiments corresponding to the above process with the AMF network element, base station, and data storage network element on the network side as the execution subject. Since all the implementation principles and detailed processes of the following embodiments with the network side as the execution subject, as well as the technical effects that can be achieved are the same as those of the above embodiments with the terminal as the execution subject, therefore, for the sake of brevity and clarity, the following embodiments will no longer be described one by one, and the implementation process and implementation effect of each embodiment can refer to the description of the aforementioned embodiments.

[0226] In one embodiment, as shown in FIG4 , a network access method is provided, which is applied to a network, and the method includes:

[0227] S401, sending an indication message to a terminal; the indication message carries the tariff status of the terminal SIM card; the indication message is used to instruct the terminal to determine or stop initiating an access request to the network according to the tariff status of the SIM card.

[0228] It should be noted that the network in the embodiment of the present application refers to the network element in the network environment where the terminal is located and can communicate with the terminal, such as the SMF network element in the 4G network, the AMF network element and the base station in the 5G network.

[0229] The network element on the network side encapsulates the SIM card tariff status in an indication message and sends it to the terminal to instruct the terminal to determine the next terminal behavior according to the indication message, that is, to initiate an access request to the network, or to stop initiating an access request to the network.

[0230] Among them, according to the actual tariff of the SIM card, the tariff status of the SIM card includes normal tariff or arrears. Furthermore, considering that in actual scenarios, the SIM card is allowed to maintain communication with the network side in the case of arrears, such as the arrears time is less than the preset time period, the arrears amount is less than the preset threshold, etc., the arrears status can be further subdivided into: arrears can use the network state, arrears can not use the network but can access the network state, arrears can not access the network state, shutdown state, account cancellation state and other states. Then in one embodiment, arrears include at least one of the following: arrears can use network services; arrears can not use network services but can access the network; arrears can not access the network; shutdown; account cancellation.

[0231] Optionally, in addition to carrying the tariff status of the SIM card, the network side may also generate corresponding terminal behavior instructions according to the tariff status of the SIM card, so that the terminal may directly determine whether to initiate an access request to the network according to the terminal behavior instructions in the indication message.

[0232] In one embodiment, the content of the indication message includes: an access indication message corresponding to the tariff status of the SIM card; or an access rejection indication reason value corresponding to the tariff status of the SIM card.

[0233] Among them, the access indication message is in text form, and the tariff status corresponding to the access indication message includes: normal tariff status, network can be used for arrears status, and network cannot be used but access can be obtained for arrears status; the access rejection indication reason value is in numerical format, and the tariff status corresponding to the access rejection indication reason value includes: network cannot be used for arrears status, network cannot be accessed for arrears status, shutdown status, and account cancellation status.

[0234] The content of the indication message provided in the embodiment of the present application takes into account the terminal behavior, encapsulates the indication messages corresponding to different terminal behaviors into different formats, and sends them to the terminal, so that the terminal can quickly distinguish whether to initiate an access request to the network according to the form of the indication message, thereby improving the effectiveness of the terminal initiating an access request to the network. In addition, due to the correspondence between the format of the indication message and the tariff status of the terminal SIM card, the terminal can further clarify the reasons for its own behavior while making the terminal behavior, making the communication between the terminal and the network more transparent and more reliable.

[0235] In the embodiment of the present application, an indication message is sent to the terminal; the indication message carries the tariff status of the terminal SIM card; the indication message is used to instruct the terminal to determine or stop initiating an access request to the network according to the tariff status of the SIM card. In this method, the network carries the tariff status of the terminal SIM card in the indication message and sends it to the terminal, so that the terminal can perceive the tariff status of the SIM card in time, avoiding the situation where the terminal frequently initiates network access requests when the SIM card tariff status does not support initiating access requests, thereby avoiding occupying a large amount of air interface resources, improving the effectiveness of the terminal initiating access requests, and improving the network air interface quality.

[0236] Below, taking the terminal in a 5G communication scenario and the interaction between the AMF network element on the network side and the terminal as an example, the method of sending the indication message is explained.

[0237] In one embodiment, the network is an AMF network element, and sends an indication message to the terminal, including:

[0238] Sending first signaling interaction information to the terminal; the first signaling interaction information carries an indication message.

[0239] The information type of the first signaling interaction information includes at least one of the following:

[0240] Response information of the attach or register message, the response information includes a rejection response message or an acceptance response message;

[0241] Response information of a mobile attach or mobile registration message, the response information including a rejection response message or an acceptance response message;

[0242] Tracking area update message response information;

[0243] Configuration update information, the configuration update information includes a dedicated configuration update or a general configuration update process;

[0244] Paging information;

[0245] A response message to a service request, where the response message includes rejecting the service request or accepting the service request.

[0246] The AMF network element encapsulates the indication message in the first signaling interaction information and sends it to the terminal. The terminal receives the first signaling interaction message sent by the core network and obtains the indication message.

[0247] In an embodiment of the present application, the AMF network element encapsulates the indication message in different types of signaling interaction information and sends it to the terminal. Correspondingly, the terminal can receive the indication message sent by the AMF network element in a variety of ways to make full use of the interactive signaling between the AMF network element and the terminal, enrich the diversity of the terminal receiving the indication message, and improve network access efficiency.

[0248] The following describes the method of sending the indication message by taking the interaction between the base station and the terminal on the network side as an example.

[0249] In one embodiment, the network is a base station, and sending an indication message to the terminal includes:

[0250] Sending second signaling interaction information to the terminal; the second signaling interaction information carries an indication message.

[0251] The information type of the second signaling interaction information includes at least one of the following:

[0252] RRC establishment process;

[0253] RRC reconfiguration process;

[0254] RRC recovery procedure.

[0255] The base station encapsulates the indication message in the second signaling interaction information, such as the RRC establishment process, the RRC reconfiguration process, the RRC recovery process and other information, and sends it to the terminal. The terminal receives the first signaling interaction message sent by the base station and obtains the indication message.

[0256] In an embodiment of the present application, the base station encapsulates the indication message in different types of signaling interaction information and sends it to the terminal. Correspondingly, the terminal can receive the indication message sent by the base station in a variety of ways to make full use of the interactive signaling between the base station and the terminal, enrich the diversity of the terminal receiving the indication message, and improve network access efficiency.

[0257] Next, a possible way for the network side to obtain the tariff status of the SIM card is described.

[0258] In one embodiment, as shown in FIG5 , the network is an AMF network element, and before sending the indication message to the terminal, the method further includes:

[0259] S501, obtaining the tariff status of the SIM card in the data storage network element.

[0260] The data storage network element refers to a network element used to store and manage user data including the tariff status of the SIM card.

[0261] In the embodiment of the present application, the data storage network element may be any one of a unified data management (UDM) network element, a home subscriber server (HSS) network element, and a unified data repository (UDR) network element.

[0262] According to the interaction mode between the AMF network element and the data storage network element, the AMF network element obtains the tariff status in two ways: active reading and passive reception.

[0263] Exemplarily, the tariff status of the SIM card is read from the data storage network element.

[0264] The AMF network element sends a tariff status acquisition request to the data storage network element, and the data storage network element encapsulates the tariff status of the SIM card in a tariff status acquisition response and sends it to the AMF network element.

[0265] Exemplarily, the received data stores the tariff status of the SIM card sent by the network element.

[0266] The AMF network element subscribes to the data storage network element's tariff status acquisition request to instruct the data storage network element to send the SIM card's tariff status to the AMF network element at regular intervals, or the data storage network element sends the SIM card's tariff status to the AMF network element in real time after receiving it.

[0267] In an embodiment of the present application, the AMF network element can obtain the tariff status of the SIM card from the data storage network element in a variety of ways to ensure the accuracy and validity of the tariff status of the SIM card.

[0268] S502: Encapsulate the tariff status of the SIM card to obtain first signaling interaction information.

[0269] After obtaining the tariff status of the SIM card, encapsulate it in any type of message including response information of attachment or registration message, response information of mobile attachment or mobile registration message, response information of tracking area update message, configuration update information, paging information, and response message of service request information to obtain the first signaling interaction information.

[0270] In an embodiment of the present application, the AMF network element encapsulates the tariff status of the SIM card in the data storage network element in the first signaling interaction information, thereby improving the information security of the tariff status of the SIM card and providing a reliable and accurate basis for the terminal to determine or stop initiating an access request.

[0271] The above is a description of the embodiments related to the AMF network elements and base stations on the network side as the execution entities. On this basis, the embodiments of the present application also provide embodiments corresponding to the above process with the data storage network element on the network side as the execution entity. Since all the implementation principles and detailed processes of the following embodiments with the data storage network element as the execution entity, as well as the technical effects that can be achieved are the same as the above-mentioned embodiments with the AMF network elements and base stations on the network side as the execution entity, therefore, for the sake of brevity and clarity, the following embodiments will no longer be described one by one, and the implementation process and implementation effects of each embodiment can refer to the description of the aforementioned embodiments.

[0272] In one embodiment, as shown in FIG6 , a network access method is provided, which is described by taking the method applied to a data storage network element as an example, and includes the following steps:

[0273] S601, sending the tariff status of the SIM card in the terminal to the AMF network element to instruct the AMF network element to send the tariff status of the SIM card to the terminal; the tariff status of the SIM card is used to instruct the terminal to determine or stop initiating an access request to the network.

[0274] The data storage network element includes any one of a UDM network element, an HSS network element and a UDR network element.

[0275] Optionally, the data storage network element responds to the tariff status acquisition request sent by the AMF network element, encapsulates the tariff status of the SIM card in a tariff status acquisition response, and sends the tariff status acquisition response to the AMF network element.

[0276] In another communication scenario, the data storage network element can send the latest saved SIM card tariff status to the AMF network element at a preset time interval, or it can monitor the SIM card tariff status. If the SIM card tariff status is updated, the latest SIM card tariff status will be sent to the AMF network element.

[0277] Next, in combination with the application background of the embodiment of the present application, the flow method and function of the SIM card's tariff status are explained: the data storage network element saves the SIM card's tariff status, and then sends the saved tariff status to the AMF network element. The AMF network element encapsulates the SIM card's tariff status in an indication message and sends the indication message to the terminal. The terminal then obtains the SIM card's tariff status based on the received indication message, and determines or stops initiating an access request according to the logical relationship between the tariff status and the terminal behavior.

[0278] In the embodiment of the present application, the data storage network element sends the tariff status of the SIM card in the terminal to the AMF network element to instruct the AMF network element to send the tariff status of the SIM card to the terminal; the tariff status of the SIM card is used to instruct the terminal to determine or stop initiating an access request to the network. In this method, the data storage network element sends the tariff status of the SIM card to the terminal through the AMF network element, so that the terminal can perceive the tariff status of the SIM card in a timely manner, avoiding the situation where the terminal frequently initiates network access requests when the SIM card tariff status does not support initiating access requests, thereby avoiding occupying a large amount of air interface resources, improving the effectiveness of the terminal initiating access requests, and improving the network air interface quality.

[0279] In one embodiment, taking the interaction scenario between the terminal and the AMF network element as an example, FIG7 provides a signaling interaction flow chart of a network access method. In FIG7, the data storage network element includes any one of the UDM network element, the HSS network element and the UDR network element. As shown in FIG7, the method includes the following steps:

[0280] S701, the data storage network element adds and stores the tariff status of the SIM card.

[0281] Among them, the tariff status of the SIM card is sent by the Internet Technology (IT) system to the data storage network element.

[0282] S702, adding a message service and interface to obtain the tariff status of the terminal SIM card.

[0283] The network elements in the core network add a message service and interface for obtaining the terminal's SIM card tariff status, including: reading, subscribing, notifying and other messages to obtain the terminal's SIM card tariff status.

[0284] Among them, the network elements in the core network include but are not limited to the access and mobility management function network element (Access and Mobility Management Function, AMF), session management function network element (SessionManagement Function, SMF), user plane function network element (User Plane Function, UPF), and policy control function network element (Policy Control Function, PCF) shown in Figure 7.

[0285] S703: The network sends an indication message to the terminal.

The interaction information may include one or more of the following: attach / registration message, TAU, periodic / mobile registration, configuration update, paging message, etc.

[0287] S704, adding a rejection reason value based on the tariff status of the SIM card.

[0288] The network elements in the core network add rejection reason values ​​based on the above-mentioned SIM card tariff status in the 5GMM cause code and 5GSM cause code, including: rejection of service due to arrears, rejection of service due to shutdown, prohibition of access due to arrears, prohibition of access due to shutdown, etc.

[0289] S705, adding paging information based on SIM card charges.

[0290] The network element in the core network adds an MT message based on the SIM card charges, or adds a paging message based on the SIM card charges.

[0291] S706, receiving updated tariff status.

[0292] The terminal supports receiving the SIM card tariff status sent by network signaling, supports receiving the SIM card tariff status through OTA, SMS, Bluetooth, WiFi, etc., and supports saving and updating the SIM card tariff status.

[0293] S707, receiving, saving and updating the SIM card tariff status information sent by the network, and retaining the SIM card tariff status information after restarting and powering on the device.

[0294] The terminal receives, saves and updates the SIM card tariff status information sent by the network, and retains the SIM card tariff status information after restarting and powering on, so as to avoid frequent initiation of network connection after restarting and powering on, resulting in waste of air interface resources.

[0295] S708, optimizing terminal behavior based on the tariff status of the SIM card.

[0296] The optimization strategies are as follows:

[0297] If the SIM card's tariff status is normal, a registration request and a service request are sent to the AMF network element. A recharge page can also be pushed to prompt the user to recharge.

[0298] If the SIM card's tariff status is in arrears and network services can be used, a registration request and service request are sent to the AMF network element;

[0299] If the SIM card is in arrears and cannot use network services but can access the network, stop sending service requests to the AMF network element;

[0300] If the SIM card is in arrears and cannot access the network, stop sending registration requests to the AMF network element;

[0301] If the SIM card's tariff status is in shutdown state, stop sending registration requests to the AMF network element;

[0302] If the SIM card's tariff status is in the cancelled state, stop sending registration requests to the AMF network element.

[0303] The network access method provided in the embodiment of the present application allows the IoT terminal to access the network or initiate a service request on demand according to the SIM card tariff status, so as to avoid the terminal still frequently and repeatedly initiating connection requests according to the inherent protocol after the core network rejects it; it also avoids the consumption of communication capacity, especially the limited wireless port channels, in the process of the terminal initiating the connection request, thereby improving the network air interface quality. In addition, the present application does not require hardware modification, but only software upgrades to achieve, thus avoiding the cost of hardware modification.

[0304] In one embodiment, FIG8 provides a signaling interaction flow chart of a network access method. As shown in FIG8, the method includes the following steps:

[0305] S801, the network adds and saves the tariff status of the SIM card.

[0306] S802, the network adds a new message service and interface to obtain the tariff status of the terminal SIM card.

[0307] S803: The network sends an indication message to the terminal.

[0308] S804: If the network denies the terminal access, the network sends a denial reason value based on the tariff status of the SIM card.

[0309] S805, the terminal receives, saves and updates the SIM card tariff status information sent by the network, and retains the SIM card tariff status information after restarting and powering on.

[0310] S806, when the SIM card's fee status is in arrears and the network is unavailable, the terminal stops initiating access requests to the network and no longer performs operations such as cell search, cell selection, and network search.

[0311] S807, the terminal receives the updated tariff status of the SIM card, and initiates an access request when the SIM card is in a network available state.

[0312] In one embodiment, Figure 9 provides a signaling interaction flow chart of a network access method. As shown in Figure 9, the method includes the following steps:

[0313] S901, the terminal receives, saves and updates the tariff status of the SIM card.

[0314] Among them, the tariff status of the SIM card can be encapsulated in the first signaling interaction information sent by the core network, or the second signaling interaction information sent by the base station, or the short message service message sent by the operator, or the Bluetooth information sent by the Bluetooth sender, or the wireless network push information sent by the wireless network sender.

[0315] S902: If the SIM card is in arrears, the terminal initiates a service request to access the network.

[0316] S903: If the network denies the terminal access, the network sends a denial reason value based on the tariff status of the SIM card.

[0317] S904, the terminal saves the SIM card tariff status issued by the network, and when the terminal is turned on and off again, the SIM card tariff status information is still retained.
