Description
Technical Field
The invention relates to the field of communication, in particular to a method and a device for configuring and processing APN parameters.
Background
Currently, there are Multiple systems coexisting in a network of an operator, such as Global system for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (Long-Term Evolution, LTE), etc., and some application-specific data services require different proprietary Access Point Names (APN) to establish Multiple parallel data links. Different users select different data services according to their own needs, so network parameters such as APN of the operator are not fixed as before, but change with factors such as a Subscriber Identity Module (SIM) card used by the terminal device, a network where the terminal device is located, time, and the like.
For the problem of real-time change of network parameters such as APN, an operator remotely performs management operations such as parameter setting of APN and the like on a data terminal adopting a protocol such as Open Mobile Alliance (OMA) DM and the like in a way of over the Air Technology (OTA for short) under the condition that a user cannot perceive the management operations, so that parameters such as APN and the like of the data terminal can be dynamically changed in real time according to the requirements of the operator.
For a data terminal, in order to meet network requirements of an operator, multiple network standards need to be simultaneously supported, and multiple SIM cards can be compatible.
This presents a problem: when an operator sets the APN for the terminal in an OTA mode, the APN setting may only be applicable to the SIM card currently used in the current equipment, if the other SIM card is inserted into the subsequent equipment, another set of parameters is needed, otherwise, the problems that the network cannot be registered or the network cannot be connected and the like are caused due to the incompatibility of the parameters such as the APN and the like, so the operator needs to issue an instruction for setting the parameters such as the APN and the like again in a remote mode, if the original SIM is inserted back to the terminal equipment again for use, the parameters need to be set again, and the parameter state before the SIM card is pulled out is recovered, which is very inconvenient for the operator and the user.
The current data terminal configuration APN parameter mode includes two modes of manual configuration and automatic configuration. The manual mode is to let the user manually input and set corresponding parameters on the UI, and this mode can set specific APN parameters according to the network, which is more flexible, but requires the user to know specific professional parameter values, which is inconvenient for the ordinary user and not good for the user experience.
The automatic matching mode is that a data terminal is configured with a global main operator fixed APN information database when leaving a factory, operator information carried by an SIM card is read when initialization is started, the operator information is generally judged according to MCC & MNC (MCC & MNC is represented by 5-7 digits before IMSI) or SPN (file identifier in an SIM card), and then corresponding information such as APN is inquired from the database according to the operator information.
The two APN configuration modes are not suitable for the situation that an operator remotely configures parameters such as the APN of the SIM card used by the terminal through OMA DM during the use process of the user.
In the related art, an effective solution is not provided yet for the problem that the network cannot be registered or connected due to incompatibility of parameters such as APN in the process of replacing the SIM card by the terminal.

In view of the above problems in the related art, the following description is provided with reference to an alternative embodiment, which combines the above alternative embodiment and its alternative embodiments.
For a terminal where an operator uses an OMA DM protocol to remotely configure parameters such as an APN, a conventional method for configuring parameters such as an APN is no longer applicable, and this optional embodiment provides a method for configuring parameters of an APN of a terminal device according to a SIM card. That is, the method for configuring the APN of the terminal according to the SIM card may be used, where the terminal records parameters according to the SIM card, and one SIM card corresponds to a group of parameters such as the APN, and when the SIM card is replaced, the parameters such as the APN of the device may be updated.
The method comprises the steps that when an operator sets a terminal through an OMA DM protocol, a SIM card used in terminal equipment and equipment APN parameters are correspondingly recorded in a database. And in the process of starting up and initializing the data terminal, inquiring corresponding APN parameter information in a database according to the IMSI of the SIM card in the equipment, and setting the terminal.
If the SIM card is detected to be pulled out, restoring the APN parameter of the terminal to a default value when leaving a factory; and if the SIM card is detected to be replaced, setting the terminal according to the APN parameter corresponding to the IMSI of the SIM card in the database.
This optional embodiment provides a method for configuring a terminal APN according to a SIM card in a device, where a database is established on the terminal to record a specific SIM card and corresponding APN parameters, fig. 5 is a structural diagram of the database table according to the embodiment of the present invention, and as shown in fig. 5, 501 is an IMSI of the SIM card, uniquely identifies a SIM card user, each IMSI corresponds to a set of terminal APN parameters 502, and multiple different APNs are used to establish different PDN links. When the terminal leaves the factory, the database is empty, and when a SIM card is inserted into the device, a record 503 is added to the database, and when an SIM card that is not used in the terminal is replaced, a record 504 of a new SIM card is correspondingly added to the database, and so on.
Fig. 6 is a flowchart of configuring a terminal APN according to a SIM card in a device when a terminal starts initialization according to an embodiment of the present invention, as shown in fig. 6, the flowchart includes the following steps:
step S602, starting up the terminal for initialization;
step S604, reading IMSI of the SIM card in the equipment;
step S606, determining whether the IMSI of the SIM card is 0, if yes, executing step S608, and if no, executing step S610;
step S608, if the IMSI of the SIM card is 0, which indicates that no SIM card exists in the equipment or the SIM card is damaged, the APN parameter of the equipment is restored to a factory default value;
step S610, if the IMSI is not 0, indicating that the inserted SIM card is an effective card, acquiring APN parameter information of the terminal equipment from the database established on the SIM card according to the acquired IMSI;
step S612, the inquiry result judges whether the record can be acquired from the database, if the acquisition fails, the inserted SIM card is used on the terminal for the first time, and the step S608 is executed for the default APN parameter of the SIM card when the SIM card leaves the factory, and the APN parameter is recovered to the default;
step S614, if the record corresponding to the SIM is obtained, the obtained APN parameter is compared with the current APN parameter of the equipment;
step S616, judging whether the two groups of parameters are the same, if the two groups of parameters are the same, indicating that the SIM card is not replaced, executing step S620, and returning without repeated setting operation; if the two are different, it indicates that the SIM card in the terminal is different from the SIM card used before the last shutdown, step S618 is executed, and the APN parameter corresponding to the SIM card acquired from the database needs to be used to set the terminal;
step S618, setting corresponding APN parameters;
step S620, no operation, return.
Fig. 7 is a sequence diagram for setting a terminal APN by a carrier DM server according to an embodiment of the present invention, as shown in fig. 7, the sequence diagram includes the following steps:
step S702, in the using process of the user, if the operator detects that APN parameter setting needs to be carried out on the terminal, establishing session connection between the DM server at the operator side and the terminal through an OMA DM protocol;
step S704, after the session is established, the DM server issues a command for setting APN parameters, and the terminal performs corresponding setting operation after analyzing the command;
step S706, after the setting action is completed, updating the IMSI of the SIM in the current terminal equipment and the latest updated APN parameter information into a database as a record, and if the database already has the data record of the SIM card, updating the original record item; and if the record entry corresponding to the SIM card is not found in the database, inserting the record into the database table. In step S708, after completing the above actions, the terminal feeds back the result of the setting action to the DM server.
When the terminal is powered off, the database is updated once, so that the aim of preventing the user from manually setting parameters such as APN on the UI from not being synchronized into the database sometimes is achieved. Fig. 8 is a flowchart of updating an APN database when a terminal is powered off according to an embodiment of the present invention, as shown in fig. 8, the flowchart includes the following steps;
step S802, a shutdown command is received;
step S804, reading parameters such as APN used by the current equipment;
step S806, inquiring the corresponding record item in the database according to the IMSI of the SIM card in the equipment;
step S808, judging whether a record exists according to the query return result, executing step S810 if the judgment result is yes, and executing step S812 if the judgment result is no;
step S810, if the record of the SIM can be read, the record of the SIM already exists in the database, and the read APN parameter of the current device is updated to the record item corresponding to the SIM card;
step S812, if the database does not have the entry of the SIM card, indicating that the SIM card is used on the terminal for the first time, 405 forming a new record by the APN parameter of the current terminal device and the IMSI of the SIM card and inserting the new record into the database.
Alternative technical solution:
in addition to the above-mentioned solutions, an alternative solution may achieve similar effects, specifically, when the operator sets the APN parameters of the terminal device remotely through the OMA DM protocol, the terminal will keep the parameters set by the operator and use them as the only valid parameters of the terminal, and set the terminal with the set of APN parameters all the time no matter what operation is performed, unless the operator sets the terminal again. This is useful when the data terminal SIM card is not always replaced.
But this solution is less flexible than the one proposed by the present invention, since the alternative does not take into account the card change situation. Some data application services of the current operator are based on data links established by different APNs, and different users select different data application services, so that the APN parameter of one SIM card may not be suitable for another SIM card even though the SIM cards belong to the same operator. When a multimode data terminal is replaced by a new SIM card, the APN parameters before the data terminal may need to be reset, and when the original SIM card is reused, the APN parameters need to be reset once, which is very inconvenient.
The optional embodiment of the invention is also suitable for the smart phone or the tablet computer with the 3G/LTE communication function.
In summary, for a data terminal that uses the OMA DM protocol to allow an operator to remotely set parameters such as APN and frequently replace an SIM card, the optional embodiment of the present invention can make the parameter setting of the APN more convenient and flexible, and can make the terminal remember the used SIM card and the corresponding parameter information such as APN, and when the user replaces the originally used SIM card, the terminal will automatically configure the previous APN parameter without the operator having to issue a command for setting the APN parameter again.
It will be apparent to those skilled in the art that the modules or steps of the present invention described above may be implemented by a general purpose computing device, they may be centralized on a single computing device or distributed across a network of multiple computing devices, and alternatively, they may be implemented by program code executable by a computing device, such that they may be stored in a storage device and executed by a computing device, and in some cases, the steps shown or described may be performed in an order different than that described herein, or they may be separately fabricated into individual integrated circuit modules, or multiple ones of them may be fabricated into a single integrated circuit module. Thus, the present invention is not limited to any specific combination of hardware and software.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
