Based on the hardware structure of the mobile terminal and the structure of the communication device, the invention provides various embodiments of the terminal network registration method.

Referring to fig. 3, the present invention provides a terminal network registration method, where in a first embodiment of the terminal network registration method, the terminal network registration method includes:

step S10, when the terminal identification card is detected to be replaced, detecting whether the modem of the terminal completes the data network registration of the new identification card after replacement;

the terminal can be selected as a mobile intelligent mobile phone or a panel, and the terminal comprises an upper processor AP and a modem, the invention is mainly used for optimizing the process of accessing the terminal into a data network, and avoiding the phenomenon that the terminal is disconnected after being accessed into the data network due to the fact that the terminal reconfigures a network access parameter list, namely an APN parameter list after being accessed into the data network, wherein the processor in figure 1 comprises the upper processor AP, the terminal upper processor AP stores various network access parameters required for accessing the data network of different operators, the network access parameter APN parameter list comprises a first initial network access parameter, a second initial network access parameter and the like, the different operators not only comprise domestic operators such as China Mobile, China Unicom and China telecom, but also comprise foreign operators, namely initial network access parameters of the foreign operators are stored in the upper processor AP, as shown in fig. 5, when receiving the configuration instruction, the upper layer processor AP110 of the terminal 100 sends a corresponding initial network access parameter APN to the terminal modem 104, and the modem 104 sends a data network registration request to a base station where the terminal is located according to the received initial network access parameter, so as to implement registration of a data network.

The data network registration is suitable for a mobile phone terminal of an Android platform or an IOS platform, when the terminal identification card is detected to be replaced by a new identification card, wherein the replacement of the terminal identification card by the new identification card comprises the replacement of the identification information of an original terminal identification card, the identification information of the identification card comprises a card number IcID and international mobile subscriber identification code IMSI information, when the original terminal identification card is replaced by the new identification card, the card number IcID and the international mobile subscriber identification code IMSI information corresponding to the terminal are both replaced, network access parameters required by the terminal registration data network can be changed for describing specific embodiments, for example, the original identification card in the terminal is an identification card of China Mobile, and then can be changed into a new identification card of China Mobile, or can be changed into other new identification cards of China Mobile with different IcID and IMSI, when the new identification card is changed into an identification card of China Mobile, the network access parameters required by the terminal to register the data network are changed completely, and when the new identification card of the terminal is changed into the identification card of the Chinese mobile, the network access parameters required by the terminal to register the data network are the same as the network access parameters corresponding to the original identification card.

Before the terminal accesses the data network, because the access of the telephone network does not need to configure parameters, the modem of the terminal sends the telephone network access request information to the base station corresponding to the current location of the terminal after the new identification card is activated, and the terminal is successfully accessed to the telephone network of the location of the terminal, and after the terminal is successfully accessed to the telephone network of the location of the terminal, the terminal locally stores the accessed telephone network information, namely the terminal stores the accessed telephone network before the data network is accessed.

The terminal detects the identification card of the terminal through the card detection module UiccCard, and when detecting that the terminal inserts a new identification card, detects whether the modem successfully performs data network registration on the new identification card according to the pre-stored network access parameters, wherein after detecting that the terminal accesses a telephone network, the terminal modem acquires the network access parameter information pre-stored in the modem, the network access parameter information pre-stored in the modem is generally the network access parameter stored in the original identification card, for a specific embodiment, before card changing, if the original identification card of the terminal is a China Mobile card, the network access parameter corresponding to the China Mobile network is stored in the modem, when detecting that the terminal changes the card, no matter the new identification card, the China Mobile identification card or other types of identification cards, the data network registration is performed according to the China Mobile network access parameter stored in the modem, that is, in this process, the modem cannot recognize the card class corresponding to the identification card.

And detecting whether the modem successfully carries out data network registration on the new identification card according to the prestored network access parameters, wherein the terminal modem sends data network registration request information to the base station according to the prestored network access parameters as long as the terminal identification card is inserted into the terminal for replacement, if the network access parameters of the terminal modem are not matched with the data network of the operator of the identification card, the data network cannot be successfully registered, and if the network access parameters of the terminal modem are matched with the data network of the operator of the identification card, the data network can be successfully registered correspondingly.

Step S20, when the modem is detected to complete the data network registration of the new identification card, acquiring the first cell information distributed in the telephone network by the terminal based on the new identification card and the second cell information distributed in the telephone network by the terminal based on the original identification card before replacement;

the area covered by the radio signal of the base station in mobile communication is called a cell. The cell information includes base station information, attached telephone network information, the terminal network state module ServiceState stores telephone network registration state information of the terminal before card replacement, and if it is detected that the new terminal identification card has successfully registered with the data network, first cell information of the terminal of the registered telephone network is obtained, as shown in fig. 6, where the first cell information includes first base station 2023 information of the current telephone network connection of the terminal, which has been stored in the network state module ServiceState by the new terminal identification card 11, the first attached telephone network information, and the second cell information is second base station 2024 information and second attached telephone network information, which are recorded and stored last by the original terminal identification card 22 in the network state module ServiceState.

The embodiment is described as an example, if the original identification card is connected to the a-zone telephone network before the identification card is replaced, and the telephone network information attached to the terminal in the a-zone is acquired, if the terminal is currently connected to the a-zone telephone network and the terminal currently corresponds to the base station information of the telephone network, the attached telephone network information is the same as the base station information connected to the original identification card before the identification card is replaced, and the attached network information is the same, so that the identification cards before and after the terminal is replaced belong to the same operator, and can be configured to access the data network according to the same APN parameter. If the terminal is currently connected to the B-zone telephone network, it is obvious that the terminal cannot be configured to access the data network according to the same APN parameter because the a-zone telephone network connected to the terminal is different from the B-zone telephone network, and in addition, although the terminal is currently connected to the a-zone telephone network, if the information of the currently registered telephone network base stations of the terminal is different, such as one is china mobile and one is china unicom, when the registered telephone networks are different, the APN parameter of the access data network is different.

Step S30, comparing the first cell information with the second cell information, and if it is detected that the first cell information is the same as the second cell information, keeping the registration state of the new identification card in the data network.

And comparing the first cell information with the second cell information, namely comparing the attached network information in the first cell information with the attached network information in the second cell information, comparing the base station information in the first cell information with the base station information in the second cell information, and if the first cell information and the second cell information are detected to be unchanged, wherein the change not only comprises that the base station information and the attached network information in the first cell information and the second cell information are all changed, but also comprises that part of the first cell information and the second cell information is changed, and if only the base station information is changed, the change can be considered.

And if the first cell information and the second cell information are completely the same, judging that the data network registration state of the new identification card is a true registration state, and not re-registering the data network. And the current data network registration information is stored, and the APN parameters are not required to be reconfigured, so that the situation of unnecessary network drop is prevented, and the user experience is improved.

Fig. 4 shows a general flow diagram of a terminal network registration process, after the modem reports the card-picking information to the AP side in step S11, step S12 is executed, that is, the terminal AP side loads the card information reported by the modem, step S13 is executed, that is, the terminal AP side establishes an alternative APN parameter list based on the loaded card information, step S14 is executed after the alternative APN parameter list is established, that is, the terminal AP side detects whether the terminal has been registered in the data network, if yes, steps S15, S16, and S17 are executed, that is, the AP side obtains the first cell information and the second cell information, compares the cell information obtained twice, and executes step S18, that is, determines whether the cell information has changed, if yes, executes step S19, determines that the terminal data registration state is a true registration state, and if not, executes step S20, S21, that is, determines that the terminal data registration state is a false registration state, when the terminal S11 is not registered with the data network, the terminal performs a network re-search in step S21.

When the terminal identification card is detected to be replaced, whether a modem of the terminal completes data network registration of the replaced new identification card is detected; when the detection modem finishes the data network registration of a new identification card, acquiring first cell information distributed in a telephone network by the terminal based on the new identification card and second cell information distributed in the telephone network by the terminal based on an original identification card before replacement; and comparing the first cell information with the second cell information, and if the first cell information is detected to be the same as the second cell information, keeping the registration state of the new identification card in the data network. The access of the telephone network does not need to configure parameters, so that the terminal has access to the telephone network at the current location before the access of the data network, and the cell information of the terminal is obtained, if it is detected that a new identification card replaced by the terminal and an original identification card not replaced by the terminal are of the same operator based on the cell information, the original network access parameters of the modem are called to perform data network registration, and the parameters do not need to be reconfigured, thereby avoiding the technical problems that the new identification card replaced by the terminal and the original identification card not replaced by the terminal are of the same operator, or the modem parameters of the modem need to be reconfigured for the accessed data network provided by the same operator, so that unnecessary network drop is caused, the power consumption in the network registration process is high, and the user experience is poor.

Further, on the basis of the first embodiment of the terminal network registration method of the present invention, a second embodiment of the terminal network registration method is provided, wherein in the second embodiment, the step of detecting whether the modem has performed data network registration on the identification card according to pre-stored network access parameters includes:

The APN parameters of different operators are stored in a database corresponding to a terminal, and the stored APN parameters are distinguished according to operator marks, after the AP side acquires and loads information of a new identification card reported by a modem, such as a card number IcID of the new identification card and international mobile subscriber identity IMSI information, all APN parameters of a target operator can be inquired from all APN parameter databases of the operator through first six MCCMNC in the IMSI information of the new identification card, wherein MCC is an operator international code, namely, each country or region has a fixed number, MNC is an operator network code and is used for identifying each operator in the country or region, an APN parameter list is established based on all APN parameters of the target operator, and particularly, the APN parameters can be a first initial network access parameter list. And the terminal is prevented from performing data network registration according to all acquired APN parameters of the target operator when the data network registration is not successfully performed according to the pre-stored network access parameters.

In the embodiment, the identification information of the new identification card reported by the modem is obtained and loaded; and acquiring a network access parameter list corresponding to the new identification card based on the identification information.
