Detailed Description
The embodiment of the application discloses a network access verification method, a network access verification device and a computer readable storage medium, which are used for improving network access experience of users. The following is a detailed description.
In order to facilitate understanding of the network access verification method, the network access verification device and the computer readable storage medium disclosed in the embodiments of the present application, a network architecture used in the embodiments of the present application is described below. Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture according to an embodiment of the present application. As shown in fig. 1 (a), the network architecture may include a terminal device 110 and a network device 120, and communication may be performed between the terminal device 110 and the network device 120. As shown in (b) of fig. 1, the terminal device 110 may include a first application 111, the first application 111 may acquire information of the terminal device 110, and the terminal device 110 may also execute an instruction or command of the first application 111.
A terminal device, which may also be referred to as a User Equipment (UE), is a device that provides voice and/or data connectivity to a user, such as an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, etc. The terminal device may be a cellular telephone, a cordless telephone, a session initiation protocol (session initiation protocol, SIP) phone, a wireless local loop (wireless local loop, WLL) station, a personal digital assistant (personal digital assistant, PDA) device, a personal computer, a desktop computer, a server, a tablet, a handheld device with wireless communication capabilities, a smart furniture, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, or a device of a next generation communication system, e.g. a terminal device in a 5G network or a terminal device in a future evolved PLMN network, or a terminal device in an NR communication system, etc.
The network device is an entity on the network side for transmitting and receiving signals, and may be a device for communicating with the terminal device, and is mainly responsible for radio resource management, quality of service (quality of service, qoS) flow management, data compression, encryption, and other functions on the air interface side. The network devices may include various forms of base stations, such as: macro base stations, micro base stations (also referred to as small stations), relay stations, access points, and the like. The network device may also include a wireless internet (wireless fidelity, wiFi) access node (AP). The network device may also include a worldwide interoperability for microwave access (worldwide interoperability for microwave access, wiMax) Base Station (BS).
The first application is a collection of programs designed to solve a specific problem with the terminal device. The first application may be available to a user.
In order to better understand the embodiments of the present application, the related art of the embodiments of the present application will be described first.
The access point name (access point name, APN) is a parameter that the terminal device must configure to access the network device, which determines the access mode by which the terminal device can access the network. In general, the APN parameter of the terminal device is already configured according to a specific carrier, the configuration file of the APN is already stored in the application processor of the terminal in advance, and the terminal device can be directly used.
A PLMN is a network that can provide land mobile services to the public. The user identification card binds with the APN of the operator, namely, a corresponding relation between PLMN and the APN of the operator is established and stored in the terminal, so that after the user inserts the user identification card into the terminal, the terminal can identify the PLMN, then determine the APN corresponding to the PLMN from the stored corresponding relation between the PLMN and the APN of the operator, and complete the access of the corresponding operator network through the APN. PLMNs of multiple operators may be distinguished by mobile country code (mobile country code, MCC) and mobile network code (mobile network code, MNC). Wherein the resources of the MCC are uniformly distributed and managed by the International Union of electric Union (international telecommunication union, ITU), and the resources uniquely identify the country to which the mobile user belongs, for example, china is 460. Each PLMN is assigned a unique MNC, 2 or 3 digits in total, for example, chinese mobile TD system using 00, chinese mobile GSM system using 01, chinese mobile GSM system using 02, chinese telecommunications CDMA system using 03.
A virtual carrier refers to a new type of telecommunications carrier that relies on leasing the communication resources of a traditional telecommunications carrier to conduct telecommunications traffic.
After the APN configuration is completed, the terminal device needs to register the network so as to access the network. The flow of access to the network is not the same for each operator. The network of a part of operators has compatibility, and network access operation of the terminal equipment can be better supported by optimizing parameters and network access flows. Another part of operators (such as operators in japan and europe) needs to check APN information before registering the network, however, there are some systems (for example, a you ban map system (Ubuntu operating system, ubuntu OS) and the like) that need to configure the checking process of the network through a user Attention (AT) instruction or an mbim instruction and the like, and this configuration process is complex. Therefore, how to adaptively check before registering a network is a problem to be solved.
Referring to fig. 2, fig. 2 is a schematic flow chart of a network access verification method according to an embodiment of the application. Wherein the method may be applied to a first application. The first application may be installed on a terminal device, which may be any terminal device having communication capabilities, processing functions and storage capabilities, and the network entry verification method may comprise the steps of:
201. information of a first PLMN is obtained from a first subscriber identity card.
The first application may obtain information of the first PLMN from a first user equipment card installed by the terminal equipment. The information of the first PLMN may include a mobile country code and a mobile network code, and the information of the first PLMN may distinguish different operators in different countries.
The terminal device may detect whether a valid network access event is received from the network device, and when a valid network access event occurs, the first application may obtain information from the first PLMN of the first user equipment card. For example, the first application may send a CIMI AT command to a communication module of the terminal device through a modem (modem), and when the communication module of the terminal device receives the CIMI AT command from the modem, the first application may send information about a PLMN corresponding to a subscriber identity card currently used, that is, information about the first PLMN. The first subscriber identity card may be a subscriber identity card used by the current terminal device.
202. And determining the first information according to the information of the first PLMN and the APN verification information.
After the first application obtains the information of the first PLMN and the APN verification information, it may determine, according to the information of the first PLMN and the information of PLMNs corresponding to the N subscriber identity cards, whether PLMNs corresponding to the N subscriber identity cards exist in the same PLMN as the first PLMN. After the first application obtains the information of the first PLMN and the APN verification information of the N subscriber identity cards, it may be determined whether information identical to the information of the first PLMN exists in the information of PLMNs corresponding to the N subscriber identity cards. The APN verification information of the subscriber identity card may include information of a PLMN corresponding to the subscriber identity card, a user name and a key, and the APN verification information of the subscriber identity card may further include an authentication type. The authentication type refers to an authentication type in which the network device verifies the identity of the user during the network access verification process. Further, N is an integer greater than or equal to 1. The subscriber identity card may be a subscriber identity module (subscriber identification module, SIM) card. Of course, the APN check information of the subscriber identity card may further include information such as a network protocol type (IPType), a source address (source), an access string (APN), and the like.
The first application may obtain APN check information for N subscriber identity cards. The APN check information may be information of N subscriber identity cards preset or stored in advance. For example, when N is 2, the first application is already preset with information of 2 PLMNs, 2 usernames and 2 passwords, where the information of one PLMN, 1 username and 1 password correspond to APN verification information of one subscriber identity card. The first application can preset or store APN verification information of N user identification cards in the form of a file, and the stored file can be in an XML format, a txt format or a format which can be read and written by other terminal equipment.
When the PLMNs corresponding to the N subscriber identity cards are the same as the first PLMN, the first application may determine the first information according to APN check information of the target subscriber identity card. The first information may include a first user name and a first password. The target subscriber identity card may be one of the N subscriber identity cards, the corresponding PLMN being identical to the first PLMN. When there is information of the same PLMN, the first application may further determine whether the number of PLMNs in the N subscriber identity cards that are identical to the number of information of the first PLMN is greater than 1. When the number is 1, the user identification card corresponding to the information of the PLMN can be selected as the target user identification card, and the first information can be acquired according to the APN verification information of the target user identification card. In this case, the first application may use the user name and password of the APN verification information of the target user identification card as the first information, that is, it may be understood that the user name of the APN verification information of the target user identification card is determined as the first user name, and the password of the APN verification information of the target user identification card is determined as the first password. In another case, the APN check information of the target user identification card may include a user name, a key, and an authentication type, and the first application may determine the user name, the key, and the authentication type of the APN check information of the target user identification card as the first information. Wherein the first information may include a first user name, a first key, and a first authentication type. When the number is greater than 1, the first application may further determine the priority levels of the plurality of subscriber identity cards corresponding to the plurality of same PLMNs, and select the subscriber identity card with the highest priority as the target subscriber identity card. Where the priority is indicated by a number, it may be indicated by other means as well. For example, a larger value may indicate a higher priority, or a smaller value may indicate a higher priority. Further, the first application may determine the first information, and the detailed description may refer to the above description, which is not repeated herein.
When the PLMNs corresponding to the N subscriber identity cards do not exist, the first application may output first prompting information for prompting the user to input information. The first prompt information may be used to prompt the user to input a user name and a password, and may also be used to prompt the user to input a user name, a password, and an authentication type. The user can input information correspondingly according to the first prompt information. For example, when the user sees that a user name and password are currently required to be input, the SIM card being used (i.e., the first subscriber identification card) can be found and the user name and password on the SIM are input to the corresponding location. When the first application detects information input for the first hint information, the input information may be determined as the second information. The first application may determine the input user name and password as the second information, i.e., may determine the input user name as the second key and the input password as the second password; the first application may also determine the input user name, password, and authentication type as the second information, i.e., the input user name as the second key, the input password as the second password, and the input authentication type as the second authentication type. After the first application determines the second information, the second information may be sent to the network device. Specifically, the first application may send the second information to the communication module of the terminal device through the AT port, and then the communication module of the terminal device may send the second information to the network device. The first application may then receive a second check result from the network device. The second check result is a check result for the second information. After the first application receives the second check result, it may be able to parse whether the second check result passes. When the second check result indicates that the check is passed, the terminal device may further start the flow of registering the network. For example, the terminal device may dial-up networking. When the second checking result indicates that the checking is not passed, the first application can output third prompting information, and the third prompting information can prompt the user that the checking is not passed.
When the first application receives the second information, the second information may be stored in the APN check information of the user identification card. The first prompt output by the first application may also include, as possible, information of the operator type (or information indicative of the operator type) for prompting the user identification card, from which the user may input the operator type (or information indicative of the operator type), for example, chinese mobile (or 46000). The first application may determine information of the PLMN in the APN check information of the subscriber identity card based on the information entered for the hint information. The first application may then store information identifying the PLMN in the APN check information of the subscriber identity card, and second information entered by the user, in the APN check information of the subscriber identity card. Under the condition, when a user uses a new user identification card, the stored APN verification information of the user identification card can be updated only by inputting the APN verification information of the user identification card once, repeated input is not needed, and an information input channel can be provided for the user, so that the network access experience of the user can be improved.
203. The first information is sent to the network device.
After the first application obtains the first information, the first information may be sent to the terminal device through the AT port. After receiving the first information, the terminal device may send the first information to the network device.
204. A first check result is received from the network device.
The first application may receive first verification information from the network device. The first check result may be a check result of the network device for the first information. Specifically, after the network device receives the first information from the terminal device, the network device may perform, according to the first information, a verification result for the first information, that is, a first verification result. The network device may then send the first verification result to the terminal device. The terminal device may receive the first check result from the network device, and after the terminal device obtains the first check result, may send the first check result to the first application. The first application may receive first verification information from the terminal device.
After the first application receives the first check result, it can analyze whether the first check result is passing or not. And when the first verification result is that the verification is passed, establishing communication connection with the network equipment, namely, the terminal equipment can start an internet injection flow, for example, the terminal equipment can dial up and internet surfing.
When the first verification result is that the verification is not passed, the first application can output second prompt information for prompting the user to input information. The second prompt information may be used to prompt the user to enter a user name and a password, or may be used to prompt the user to enter a user name, a password, and an authentication type. The user can input information correspondingly according to the second prompt information. For example, when the user sees that a user name and password are currently required to be input, the SIM card in use can be found and the user name and password on the SIM are input to the corresponding location. The first application may then receive third information entered by the user for the second prompt. The third information may be different from the first information, and may include a third user name and a third password, and the third information may also include a third user name, a third password, and a third authentication type. The detailed description of determining the third information may refer to the description of determining the second information in step 202, which is not described herein.
After the first application determines the third information, the third information may be sent to the network device. The third verification result from the network device may then be further received. The third verification result may be a result of the network device verifying the third information. For the detailed description, reference may be made to the above description of transmitting the second information and receiving the second check result. It should be understood that, after the verification of the first verification result fails, an input channel may be reserved for the user, so that the user may input the APN verification information of the currently used user identification card. At this time, there may be a case where the information of PLMNs corresponding to the plurality of subscriber identity cards is the same as the information of the first PLMN, but there may still be a case where the user name and the password of the first information are not legal subscribers to which the network device belongs. For example, when the information of the PLMN of the virtual operator existing with the operator of the currently accessed network device (the virtual operator and the operator of the currently accessed network device are not the same operator) may be the same information, the network device may determine that the verification is not passed if the user needs to access the network of the virtual operator, but the first information is sent to the operator of the currently accessed network device. In order to avoid the above situation, the first application may be a channel for providing information input by a user, where the information of the PLMN of the subscriber identity card corresponding to the third information is not the same as the information of the first PLMN, and may be sent to the network device, so as to obtain the verification result. Therefore, the probability of success of verification before network access can be improved, and network access experience of users can be improved.
When the first application receives the third check result, whether the third check result passes or not can be analyzed, and when the third check result passes, the terminal equipment can start the network injection flow. When the third verification result is that the user fails to pass, the first application can output fourth prompt information, and the fourth prompt information can prompt the user to verify that the user fails to pass.
Referring to fig. 3, fig. 3 is a flow chart of another network access verification method according to an embodiment of the application. Wherein the method may be applied to a first application. The first application may be installed on the terminal device. As shown in fig. 3, the network entry verification method may include the following steps.

the detailed description of step 301 may refer to the related description of step 201, which is not described herein.
302. Judging whether PLMNs corresponding to the N user identification cards exist the same as the first PLMN or not according to the information of the first PLMN and the information of PLMNs corresponding to the N user identification cards.
303. When PLMNs corresponding to the N subscriber identity cards are the same as the first PLMN, the first application determines first information according to APN check information of the first subscriber identity card.
304. When PLMNs which are corresponding to the N user identification cards and are the same as the first PLMN do not exist in the PLMNs, the first application outputs first prompt information for prompting the user to input information and receives second information which is input by the user aiming at the first prompt information.
The first application may further send the second information to the network device, after which the second check result from the network device may be received.
The descriptions of steps 302-304 may refer to the descriptions of step 202, and are not described herein.
305. The first application sends first information to the network device.

307. The first application judges whether the first check result is passing check.
308. And when the first verification result is that the verification is passed, the first application establishes communication connection with the network equipment.
309. When the first verification result is that verification fails, the first application outputs second prompt information for prompting the user to input information, and receives third information input by the user aiming at the second prompt information.
The first application may further send third information to the network device, after which a third check result from the network device may be received.
