Description

OTA APN upgrading method, device, equipment and medium
Technical Field
The invention relates to the technical field of computers, in particular to a method, a device, equipment and a medium for upgrading APN by OTA.
Background
OTA upgrade refers to a standard software upgrade mode provided by an Android system, and can upgrade the system without loss, and the main means is to automatically download an OTA upgrade package and automatically upgrade through a network (including WIFI and 3G/4G); and also supports the upgrade of the SD card by downloading an OTA upgrade package.
The apn (access Point name) is a network access technology, and is a parameter that must be configured when a device terminal accesses the internet, and determines which access mode the mobile phone accesses the network.
The APN code and loading process specifically includes:
(1) APN code
From the APN code, the APN surfing parameters of each operator are stored in an xml file, such as: apns-conf.xml; the system is compiled when it is compiled into the mirror image of the system. The format of APN parameters in Xml is as follows:
Figure BDA0002256045080000011
(2) APN loading process
1. The Android system is designed in such a way that the initialization of the APN is performed only after the system is started for the first time, and the system reads the APN file from the system mirror image file system and analyzes data after the system is started for the first time. If the equipment does not have a telephony.db database, the telephony.db database is established first, and then APN parameters of each operator, which are analyzed from the read APN file, are stored in the telephony.db database, such as parameters of mnc, mcc, APN, type and the like; if the device has a telephony.db database, no updating of the APN is performed.
2. And setting an APN list displayed on an interface, displaying only the APN of the value combination (46000) of the MCC and the MNC of the currently inserted SIM card, searching a telephony.db database through the MCC and the MNC, searching which APNs are MCC of 460 and MNC of 00, namely 46000, and then displaying the APNs on a UI interface. If there is no APN or APN parameter error corresponding to mcc/mnc in the database of telephony.db, it will not be possible to establish data connection and to surf the internet when the device terminal registers to the 46000 operator.
It can be seen that the above upgrade method has the following disadvantages:
1. some manufacturers only modify an APN-conf.xml file, and push the compiled OTA packet to a terminal user, so that the user updates the OTA packet without effect of APN update, and the update is effective after reset (or factory setting recovery); this is because the OTA upgrade updates three fields, boot, recovery, system, and APN belongs to the DATA field, and the OTA upgrade is not involved, so the update must be valid after reset (or factory reset).
Such as: the terminal does not initially add the APN parameters of the operators in the country A, namely the database telephony.db also does not have the APN parameters of the operators in the country A, once the equipment is sold in the country or a user holds the terminal to use in the country A, the user cannot surf the internet because of no APN parameters, and the user can surf the internet only by manually setting the APN to be added.
Then if only by the above technique, the xml file is compiled into system images, also OTA to those terminal devices, although with the addition, in order to integrate the national APN into the terminals that have been shipped. Db will not be upgraded APN to the database because the boot process detects that the APN is invalid.
2. The existing OTA package upgrading script adds a step of automatically deleting a telephony.db database, APNs manually added by a user are deleted and lost, for example, the user adds a special network APN or a foreign APN through a setting interface, the APN is stored in the telephony.db database, and the added APN is lost after the OTA package upgrading is finished because the telephony.db is deleted.
Disclosure of Invention

One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:
1. the APN update is valid without reset or factory reset.
The invention judges whether to upgrade by comparing the value of the version parameter of the APN _ version.xml file of the file system with the compiling version number of the terminal, but not by detecting whether to have a telephony.db database, so that the APN cannot be upgraded to the database because the telephony.db database is detected in the starting-up processing process, and the invention can read the APN parameters of each group of APN-conf.xml file in the system and update the APN parameters to the telephony.db database.
2. The APN originally added by the user of the equipment terminal cannot be deleted and lost due to OTA upgrading.
In the starting process of the invention, whether the APN parameters of each group of APNs-conf.xml in the system are updated to the telephony.db database is determined without judging the existence of the telephony.db database, so the telephony.db database is not deleted in the OTA upgrading process, and APNs manually added by ordinary users are not deleted after being stored in the telephony.db database and can still be used.
The upgraded APN can only upgrade the APN of an individual operator, and the APN of all operators is not upgraded together.
The invention reads each APN parameter in the APN-conf.xml file one by one, and then searches whether the APN parameters in the telephony.db database contain the APN parameters and whether the APN parameters are the same. If the databases already have the APN which is the same, the APN is not upgraded, and if the databases do not have the APN which is the same or different, the APN is updated to a telephony.
