Description
Technical Field
The present disclosure relates to the field of electronic technologies, and in particular, to a method and an apparatus for network residence after authentication failure.
Background
Generally, a bidirectional authentication scheme is adopted for authentication operations performed in a UMTS (Universal Mobile Telecommunications System) network and an LTE (Long Term Evolution) network, that is, a network-side device needs to authenticate a terminal and the terminal also needs to authenticate a network-side device. However, in the process of bidirectional authentication, the terminal may fail to authenticate the network-side device. More common authentication failures include MAC (Media Address Control) failure and synchronization failure (sync failure).
For synchronization failures, some authentication failures are only temporary failures. However, according to the UMTS and LTE protocols, the network side device may refuse to perform authentication again in a short time if synchronization failure occurs twice in succession. Further, the terminal sets a Subscriber Identity Module (SIM) card to an invalid state. The terminal is in a offline state if the SIM card attempting to access the LTE network is in an invalid state.
In the related art, in order to automatically restore the terminal to the normal networking state from the offline state, the terminal automatically starts a timer when encountering an invalid state of the SIM card due to a continuously generated synchronization failure. And then, after the time set by the timer is over, the networking is retried and the SIM card is authenticated. The timer is set because the network side device will refuse the terminal to authenticate again in a short time.
In the above-mentioned technology, although this way may make the SIM card network successfully, since the network side device is specified in the communication protocol not to repeatedly process the authentication request of the terminal within a short time after the terminal fails to authenticate, the time set by the timer cannot be too short, which may result in too long network access waiting time.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The embodiment of the invention provides a network residence method after authentication failure, which can be realized by a terminal. The terminal can be a mobile phone, a tablet computer, a desktop computer, a notebook computer and the like. The terminal may include a processor, memory, transceiver, etc. The processor may be a CPU (Central Processing Unit), and the like, and may be configured to detect whether the user identification card enters an invalid state due to authentication failure, determine a second network system supported by the terminal, which is different from the first network system, switch the first network system to the second network system, perform network access Processing based on the second network system, and the like. The Memory may be a Random Access Memory (RAM), a Flash Memory (Flash Memory), or the like, and may be configured to store received data, data required by the processing procedure, data generated in the processing procedure, or the like, such as authentication information returned by the network side device. Further, the transceiver may include an antenna, a matching circuit, a modem, and the like. The transceiver can be used for data transmission with network side equipment such as a base station, so as to perform SIM card-based authentication operation, voice call and other operations.
The terminal may also include input components, display components, audio output components, and the like. The input component may be a touch screen, a keyboard, a mouse, etc. The audio output component may be a speaker, headphones, or the like.
An exemplary embodiment of the present disclosure provides a network residence method after authentication failure, as shown in fig. 1, a processing flow of the method may include the following steps:
step S110, in the process of carrying out network access processing based on the first network type, when the SIM card authentication is detected to fail and the SIM card enters an invalid state, determining a second network type supported by the terminal except the first network type.
Optionally, the first network system is any one of the following network systems: 5G, 4G, 3G; the second network standard is any one of the following network standards: 5G, 4G, 3G and 2G.
Because the terminal can communicate more safely in the high-level network system and the data transmission is faster, the terminal can preferentially select to access the network in the high-level network system. It should be noted that, networks in high-level network systems such as 4G and 3G generally adopt a bidirectional authentication scheme for authentication. In the process of bidirectional authentication, a phenomenon that the terminal fails in authentication with the network-side device may occur, and the authentication failure includes MAC failure and synchronization failure, which are relatively common. According to the UMTS and LTE protocols, if synchronization failure occurs twice continuously, the network side equipment can refuse the terminal to authenticate again in a short time. Further, the terminal sets the SIM card to an invalid state.
For synchronization failure, the authentication parameters sent by the terminal in the receiving network side device include SQN (sequence number), and the terminal can authenticate the network side device based on the sequence number: the terminal can verify whether the SQN is in an effective range or not based on a preset verification rule, and if the SQN is not in the effective range, a synchronization failure can occur. The SQN is set to prevent other people from impersonating network side equipment to intercept the authentication parameters of the legal user terminal, and the intercepted old authentication parameters are used for linking the terminal of the legal user.
In implementation, when it is detected that the SIM card authentication fails and enters an invalid state, a second network type supported by the terminal may be determined, except for the first network type. For example, a mobile phone supporting 4G and 3G networks performs authentication after being powered on, and first, the mobile phone automatically selects the 4G network. Next, the network access process is performed based on the 4G network, but synchronization failure may occur twice in succession, and the SIM card is set to the invalid state. Therefore, the mobile phone can detect that the SIM card enters an invalid state. Based on the method provided by this embodiment, the mobile phone will continue to determine other network types supported by the mobile phone, such as 3G network, besides 4G network.
Optionally, in a case that the terminal cannot successfully access the network of the first network standard, the highest-level network standard supported by the terminal except the first network standard may be preferentially selected to try network access again. The network standards are 5G, 4G, 3G and 2G from high level to low level. Accordingly, as shown in fig. 2, step S110 may include: step S210, determining the highest level network standard supported by the terminal except the first network standard; step S220, determining the highest-level network type as the second network type.
It should be noted that, because the terminal performs communication in a high-level network system more safely and data transmission is faster, when a network accessing the first network system fails, network access can be attempted again based on the highest-level network system among other network systems except the first network system, so as to ensure that the mobile phone operates in a high-quality network environment in a possible situation.
For example, a mobile phone supporting 4G, 3G, and 2G, GPRS networks performs authentication operation after being powered on, and determines that the selectable network standard is a 3G or 2G, GPRS network when it is detected that the network access based on the first network standard, for example, 4G, fails. Then, the mobile phone can query and compare in a preset network system level list, and determine that the network system level corresponding to the 3G network is the highest, so that it is determined that the highest level network system supported by the terminal except the first network system is the 3G network. And finally, determining the 3G network as a second network system.
Of course, if the terminal fails to perform network access under the 3G network first, the 4G network may be preferentially selected to attempt network access again.
And step S120, switching to a second network type, and performing network access processing based on the second network type.
Optionally, the specific processing procedure of performing the network access processing based on the second network type may be as follows: sending a network access request to network side equipment corresponding to the second network type; receiving authentication information returned by the network side equipment based on the network access request; and under the second network mode, performing authentication operation based on the authentication information.
In implementation, when the terminal fails to access the network of the first network type, the terminal may not send a failure report to the first network-side device corresponding to the network of the first network type, and may directly and actively send an authentication request to the second network-side device corresponding to the network of the second network type, so as to quickly attempt to access the network of the second network type. And when the second network side equipment receives the authentication request, the encrypted data is returned to the terminal, the terminal analyzes the encrypted data based on the authentication information in the local SIM card after receiving the encrypted data, and returns the analysis result to the second network side equipment. And after the second network side equipment receives the analysis result, matching the analysis result with the local authentication data of the second network side equipment, and if the matching is successful, the second network side equipment successfully authenticates the terminal.
In a communication system, taking a 2G network as an example, during a network access process, a terminal first generates an authentication request and sends the authentication request to an MSC (Mobile Switching Center). Then, the MSC requests Authentication parameters from an AUC (Authentication Center). Then, AUC calculates sres (i) by a3 one-way algorithm (an algorithm for encrypting the process of transmitting 2G communication transmission information) according to a random number generated by the random number generator and KI (Key Identifier), and sends an authentication parameter including the random number and sres (i) to MSC. Then, MSC stores SRES (i) in received authentication parameters in local, generates user side authentication request based on random number and sends the request to terminal through base station. The terminal calculates RES (i) according to the received random number and KI pre-stored locally through the still A3 algorithm. Subsequently, the terminal generates a user authentication response based on res (i) and sends it to the MSC. Finally, MSC compares RES (i) with SRES (i), if RES (i) is equal to SRES (i), the authentication is successful, if not, the authentication is failed.
Optionally, when the network access processing based on the second network type still fails, a network type easy to be successfully authenticated may be selected for network access. Correspondingly, the second network standard is a network standard needing authentication, wherein the second network standard needing authentication is a network standard except for 2G; the method provided by the embodiment further comprises the following steps: and when the authentication failure of the network access processing based on the second network standard is detected, switching to a preset third network standard without authentication, and performing the network access processing based on the third network standard, wherein the third network standard is 2G.
The 2G network adopts a one-way authentication scheme, the terminal does not need to authenticate the network side equipment, and because the terminal only authenticates the terminal by the network side equipment, the synchronization failure which can be caused by the authentication of the terminal to the network side equipment can not occur, and furthermore, the one-way authentication scheme of the 2G network is easier to ensure the successful authentication compared with the two-way authentication scheme of the 4G and 3G networks.
Based on the method provided by the embodiment, after the authentication is successful, the network signal of the cell base station can be searched, and the network selection operation can be performed after the available network signal is searched, so that the network signal which is stable and has high signal strength can be selected for network camping. After the network is successfully established, the terminal can normally communicate.
By the method provided by the embodiment of the disclosure, when the user identity identification card is detected to fail in authentication and enter an invalid state, the operation of switching the first network system to the second network system can be automatically initiated, and the network access processing is performed based on the second network system, so that the network access is retried after the network system is switched.

the determining module 310 is configured to, in a process of performing network access processing based on a first network type, determine, when it is detected that authentication of a user identity card fails and enters an invalid state, a second network type supported by a terminal, which is different from the first network type.

and the second switching module is used for switching to a preset third network standard without authentication when the authentication failure of the network access processing based on the second network standard is detected, and performing the network access processing based on the third network standard, wherein the third network standard is 2G.
