Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and a system for upgrading terminal software.
Background
The Over The Air (OTA) technology is a technology for remotely managing Subscriber Identity Module (SIM) data and applications through an Air interface of Mobile Communication (Global System for Mobile Communication, GSM) or Code Division Multiple Access (CDMA). The air interface may employ Wireless Application Protocol (WAP), General Packet Radio Service (GPRS), CDMA1X, and short message technology. The application provider or the terminal manufacturer can continuously update the product software to form an upgraded version according to the problems encountered in the using process of the user and the feedback opinions. In order to facilitate the user to operate, the upgraded product software is usually compressed into an OTA upgrade package to be stored in the server, and the OTA upgrade package is downloaded and upgraded by the user. A common upgrade process includes the following steps: firstly, a user sends a version query request to a server through terminal equipment used by the user, wherein the version query request carries version information of the current version of the terminal equipment, such as a version number and the like. After receiving the version inquiry request, the OTA server traverses all locally stored versions, compares the versions with version information carried in the version inquiry request, if a software version with a higher version number exists, the server returns to an upgradable state, and a user determines whether to upgrade, if the user determines to upgrade, the server pushes an address of a current upgradable version to the terminal equipment, and the terminal equipment downloads an updated version from the server according to the received address and automatically upgrades the updated version.
Under GSM or CDMA networks, limited by network bandwidth, a conventional OTA upgrade scheme is used, on the one hand, when downloading upgrade packages of around 100 MB. If the network quality is not good, more than half an hour is needed, and even the situation of upgrading failure occurs, which seriously affects the actual experience of the user. On the other hand, in the same base station, if the number of terminals upgraded at the same time is large, the actual download rate of each terminal is also reduced, the download time is prolonged, and the user experience is poor.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and examples.
The terms "first," "second," "third," and the like in the description and in the claims, and in the drawings, are used for distinguishing between different objects and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference throughout this specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. One skilled in the art will appreciate that the embodiments described herein can be combined with other embodiments.
A flow chart of the steps of a terminal software upgrading method is shown in fig. 1, which is based on OTA technology. The OTA remotely manages the SIM card data and applications through the air interface of the mobile communication (GSM or CDMA), which may use WAP, GPRS, CDMA1X, short message technology, etc. When the network quality is poor or the number of terminals to be upgraded is large, the user experience of terminal software upgrading based on the OTA technology is poor, and in order to improve the situation, the control flow shown in fig. 1 is specifically designed.
Step S101, the terminal accesses at least one data network and generates a software upgrading request.
It will be understood by those skilled in the art that the terminal may be a mobile phone, a notebook computer, a tablet computer or other mobile terminal having a SIM card module, and the form of the terminal is not further limited herein. The terminal is provided with application software, and a provider of the application software provides upgrading service of the application software based on OTA technology. When the terminal performs OTA software upgrade, at least one data network, namely GSM or CDMA, needs to be accessed based on a corresponding communication protocol and a software upgrade request is generated. The software upgrade request may be automatically generated or may be generated autonomously by the end user.
Step S102, the terminal obtains the real-time communication parameters of the current data network, and compares the real-time communication parameters with the set communication parameters.
Unlike the prior art, the terminal is configured with the set communication parameters immediately before shipment. The set communication parameters are obtained through a large number of experiments and are enough to match the normal downloading of about 100M compressed packets. After accessing a data network and generating a software upgrading request, the terminal acquires the real-time communication parameters of the current data network, and automatically compares the real-time communication parameters of the current data network with the set communication parameters to judge whether the network conditions of the current data network are enough to match the normal downloading of about 100M compression packets.
And step S103, if the real-time communication parameters are better than the set communication parameters, the terminal further calls the data network identification of the data network.
The data network identification may be a mobile network number, a physical cell identification, a cell number of a wireless network base station, a reference signal received power, a base station number, etc. And the terminal attaches the data network identification of the called network to the software upgrading request.
And step S104, the terminal sends a software upgrading request and a data network identifier to the server.
Step S105, after receiving the software upgrading request and the data network identification, the server reads the current upgrading state of the area corresponding to the data network identification according to the data network identification.
For example, if the data network identifier is a physical cell identifier, after receiving the software upgrade request and the data network identifier, the server reads the current upgrade status of all mobile terminals in the physical cell corresponding to the physical cell identifier according to the physical cell identifier, that is, knows the network status in the current area.
Step S106, the server stores the one-to-one corresponding relation between the data network identification and the standard area upgrading state of the corresponding area. After receiving the software upgrading request and the data network identifier sent by the terminal, the server can read the standard area upgrading state corresponding to the data network identifier. The server compares the current area upgrade status read in step S105 with the standard area upgrade status read according to the data network identification. If the current area upgrading state does not exceed the standard area upgrading state, the network condition in the current area can meet the user requirement, and the condition that the user upgrading use experience is reduced cannot occur. Under the condition, the server responds to the software upgrading request and feeds back response information to the terminal
Different from the prior art, the terminal software upgrading method further configures the terminal and the server, configures the set communication parameters in the terminal, configures the standard area upgrading state in the server, and performs double evaluation on the network conditions on the terminal and the server by using the set communication parameters and the standard area upgrading state when the terminal generates the software upgrading request, so that the user software upgrading service is provided only under better network conditions, and the use experience of a user is improved.
The following describes the interaction process of the whole software upgrading method in detail with reference to the control flow diagram at the terminal side in fig. 2 and the control flow diagram at the server side in fig. 3.
As shown in fig. 2, the terminal accesses at least one data network and generates a software upgrade request.
The terminal firstly obtains the packet loss rate and the time delay of the ping data packet between the terminal and the server through the ping instruction, namely obtains the real-time communication parameters of the current data network.
The terminal is pre-configured with standard network packet loss rate and time delay before leaving the factory, that is, communication parameters are set. After the packet loss rate and the time delay of the current data packet are obtained, the terminal compares the packet loss rate and the time delay of the current data packet with the standard network packet loss rate and the standard network time delay. I.e. to determine whether the current network conditions are better than a pre-configured threshold of network conditions.
If the real-time communication parameters are better than the set communication parameters, the current network quality meets the downloading requirement. The terminal further invokes the data network identification of the data network, i.e. the base station number and the physical cell number of the currently connected data network.
The terminal sends a software upgrading request carrying the base station number and the physical cell number of the currently connected data network to one end of the server.
The terminal further enters a waiting state to judge whether response information fed back by the server is received in a set period.
If the real-time communication parameters are inferior to the set communication parameters or the response information fed back by the server is not received in the set period, the upgrading process is finished, and the problem of reduced user experience caused by poor network quality is avoided.
At one end of the server, after receiving the software upgrading request and the data network identifier, the server inquires whether an updated version exists at present.
If the server end stores the update version, the server inquires and calls the current area upgrading state of the area corresponding to the data network identification according to the data network identification, namely the base station number and the physical cell number, namely the number of the terminals which are upgrading under the same base station and the same physical cell.
The server further judges whether the current area upgrading state exceeds the standard area upgrading state, namely judges whether the number of the terminals which are upgrading under the same base station and the same physical cell is larger than or equal to the maximum number of the terminals which are in the software upgrading state in the same base station and the same cell.
And if the number of the terminals under upgrading in the same physical cell of the same base station is smaller than the maximum number of the terminals in the software upgrading state in the same cell of the same base station, the server responds to the software upgrading request and feeds back response information to the terminals.
And at the terminal end, after response information fed back by the server is received in a set period, whether an upgrade permission instruction set by a user is received is further judged. If the upgrade allowing instruction is received, the download of the upgraded version of the compressed package is started.
And the server updates the number of the terminals in the software upgrading state in the same cell of the current same base station in the downloading process. Specifically, when the terminal starts to download the compression package of the upgrade version, the server updates the current upgrade state, and the number of terminals in the software upgrade state in the same cell as the current base station is increased by one. And after the downloading is successful, the server updates the current upgrading state again, and the number of the terminals in the software upgrading state in the same cell of the current base station is reduced by one, so that the accuracy of the current region upgrading state which can be called is ensured, and the requirement of simultaneously updating a plurality of terminals is met.
And at one end of the terminal, after the downloading is finished, the terminal feeds back a downloading success signal to the server. Of course, at one end of the server, the number of software upgrade states in the same cell as the current base station may be updated again after receiving the download success signal fed back by the server.
In another aspect, as shown in fig. 4, the invention also discloses a terminal software upgrading system. The terminal software upgrading system is composed of a plurality of modules.
A generating module, configured to generate a software upgrade request when the terminal accesses at least one data network.
And the acquisition module is used for acquiring the real-time communication parameters of the current data network, comparing the real-time communication parameters with the set communication parameters.
The set communication parameters are configured in the terminal before the terminal leaves a factory and can be called at any time. The set communication parameters are obtained through a large number of experiments and are enough to match the normal downloading of about 100M compressed packets. The acquisition module acquires the real-time communication parameters of the current data network, and automatically compares the real-time communication parameters of the current data network with the set communication parameters to judge whether the network conditions of the current data network are enough to match the normal downloading of about 100M compression packets.
A calling module for calling a data network identifier of the data network.
And when the real-time communication parameters are better than the set communication parameters, the calling module calls the data network identification of the data network. The data network identification may be a mobile network number, a physical cell identification, a cell number of a wireless network base station, a reference signal received power, a base station number, etc.
And the sending module is used for sending the software upgrading request and the data network identification to the server when the real-time communication parameters are better than the set communication parameters.
And when the real-time communication parameters are better than the set communication parameters, the sending module sends a software upgrading request attached with the data network identification to the server.
And the reading module is used for reading the current area upgrading state of the area corresponding to the data network identifier according to the data network identifier.
After receiving the software upgrading request and the data network identification, the reading module reads the current upgrading state of the area corresponding to the data network identification according to the data network identification. For example, if the data network identifier is a physical cell identifier, the reading module reads the current upgrade status of all mobile terminals in the physical cell corresponding to the physical cell identifier according to the physical cell identifier, that is, knows the network status in the current area.
And the feedback module is used for responding to the software upgrading request and feeding back response information to the terminal when the current area upgrading state does not exceed the standard area upgrading state.
If the current area upgrading state does not exceed the standard area upgrading state, the network condition in the current area can meet the user requirement, and the condition that the actual upgrading use experience of the user is reduced cannot occur.
In a preferred embodiment, the setting of the communication parameter includes setting a network packet loss rate and setting a network delay, or setting one of the network packet loss rate and the network delay.
The data network identity is preferably the base station number or cell number to which the terminal is attached.
The current area upgrading state is the number of terminals in the software upgrading state in the same cell of the same base station, and the standard area upgrading state is the maximum number of terminals in the software upgrading state in the same cell of the same base station.
In a preferred embodiment, the terminal software upgrading system further includes:
and the judging module is used for judging whether an upgrade permission instruction is received or not after the terminal receives the response information. Namely, whether the user allows upgrading is judged, and downloading is carried out only under the condition that the user allows upgrading.
And the updating module is used for updating the number of the terminals in the software upgrading state in the same cell of the current same base station in the process of downloading the upgrading version from the server by the terminals so as to ensure that the current region upgrading state which can be called is accurate and meet the requirement of simultaneously updating a plurality of terminals.
