Method and Arrangement for Installing an Application in Wireless Environment
Field of the Invention This invention relates to the installing of an application in a mobile terminal. Particularly the inventions relates to downloading a service to the terminal. Further, the invention relates to the telecommunications of the mobile terminal for making the downloaded application possible to use properly.
Background of the Invention
It is known to install an application through the Internet to a distant terminal. Particularly, this is the situation in fixed terminals, which have been connected to the Internet via subscriber lines. The fixed terminals have usually good resources for telecommunications. Practically every terminal in a fixed network is capable just to download and install a desired application.
The situation is not so good in mobile networks. The resources of the mobile networks are limited to handle telecommunication, as are the resources of mobile terminals as well. The bandwidth of the wireless path is narrow, and the memory size and processing power is limited in a mobile terminal. If the user of a mobile terminal desires to download and install an application, he must study detailed instructions, which is very tedious and error prone.
In other words, the downloading and the installing of an application requires special knowledge, so that these can be done properly. A normal user of a mobile terminal becomes confused when reading the downloading installing instructions. The complexity rises from the fact that a number of different wireless telecommunication solutions require their own type of connections. The solutions in the fixed network side are not possible, since the resources of the communications paths and the mobile terminals are limited. The object of the invention is to eliminate these drawbacks and to achieve a solution, which is capable to download and install an application in a mobile terminal and which is user-friendly. The object is achieved in a way described in the claims.
Summary of the Invention
In an inventive solution a special component, called an installer, which can be pre-installed or installable from a service provider's server, is in a mobile terminal. When a user desires to download an application for his use, he writes an SMS message that is sent to the service provider's server via SMSC. As a response the provider's server sends to the installer in the user's mobile terminal an SMS message that contains setup information for the telecommunication connections of the installer so that the installer is capable to download the desired application. The SMS message may also con- tain setup information for the desired application.
So, the underlying principle of the invention is that the installer is a small application that does not consume much memory in the mobile terminal, and for setting the installer up for a required use the setup data comes from outside the terminal. The same applies to the desired application as well. In other words, the installer is adaptable to any download and installation situation with minimum memory consumption. Furthermore, the required operations are made automatically without any actions by the user.

FIG. 3 illustrates an example of a flow chart describing an embodiment of the inventive method.
Description of the Invention
FIG. 1 shows an example of an inventive arrangement. When the user of a mobile terminal 1 desires to use a certain application or service, he writes an SMS (Short Message Service) message, containing the information of the desired application or service, which message the mobile terminal sends 11 to a server 7 of a provider, who offers installation services for pro-
viders of different applications. The SMS message is transferred via a SMSC (Short Message Service Center) 2.
The server 7 sends 12, as a response to the received message, an SMS message back to the mobile terminal 1 via the SMSC. More.particu- larly, this message is sent to an installer 3 in the mobile terminal. The response SMS contains setup data for the installer's telecommunication settings. The setup data is not pre-installed in the installer, since the memory resources of the terminal are limited, and service providers and application providers have usually their own requirements for telecommunication set- tings. The installer would become large and tedious to update, if the installer contained telecommunication settings for all possible providers. However, it is possible to have some initial telecommunication settings in the installer according to the invention. The response SMS contains an address information of the desired application or application, which is needed for the desired ser- vice.
The installer 3 sets up its telecommunication settings and requests 13 the application from a network element 4, where the application is according to the address information. The request may, for example, be according to the HTTP protocol using its GET command: GET http://www.serviceprovider.com/video/news/band34.html. As a response the application is sent 14 to the installer - in other words the installer downloads the application utilizing the telecommunication connection just set up. After the download, the installer may preferably delete the telecommunication settings. The installer is now capable to install 15 the required application 5.
It should be noted that there are actually two possible ways to deliver the needed application information to the installer. The preferable way is that the SMS message from the SMS server 7 to the installer also contains setup information, such as different parameters, for the telecommunication settings and other possible settings of the application. In other words, the application may be a simple platform, which is configured to run in the installer according to the setup information received from another source than the application itself. The benefit of this solution is that application providers may manufacture a generic application that is suitable for different solutions. Customer specific settings can be in the installer as described, or using pre-installed settings information, but this alternative is not the preferable one. The other
way is that the application itself contains setup information, or the setup data is sent to the installer with the application. It may also be possible that the message from the source of the application to the mobile terminal contains the basic application and separately the setup information of the application. After the installation 15 the application in the mobile terminal is ready to run. Let's think of an example in which the user has ordered in the SMS message a pay-TV service for viewing news in his terminal. The application that is required for seeing the news has been downloaded to the terminal in the above-described way. The application requests 16 the news from a certain news service 6, such as a server of an international media house. As a response, the service element 6 sends 17 the news to the terminal. After the news the application is preferably deleted, or it may alternatively be stored for later use.
The telecommunication settings for the connection between the installer 3 and the source 4 of an application can be any suitable type of connection. It can be, for example a GSM-data connection that means data transmission in a GSM network. Other alternatives are, for example, HSCSD (High Speed Circuit-Switched Data) and GPRS (General Packet Radio System). The HSCSD utilizes 2 - 8 timeslots for data transmission instead of one timeslot as the basic transmission in the GSM network. The GPRS is a third generation technique and a packet switched transmission system. It makes possible direct transmission between the mobile network and the Internet or another packet switched network, such as X.25. TCP/IP based and WAP based protocols are possible to use for the communication between the in- staller and the source of the application. As can be noted, a variety of different techniques and protocols exist. Furthermore, operators and providers may have specific settings for their applications and/or services.
For example, in the case of the GPRS/TCP/IP connection the telecommunication settings are: Name of the connection <name>
Access Point Name <operator defined name> Transport <GPRS> User Identification <Uid> Password prompting <yes/no> Password to be used <******>
Authentication <Stong/weak>
Gateway IP address <123.122.5.0> .
The telecommunication settings of the application 5 are usually different than the communication settings of the installer 3. The application's settings may, for example, configure a connection for an MSS (Multimedia Messaging Service).
FIG. 2 illustrates an installer according to the invention. It comprises a first means 21 for receiving a message, which contains setting information for the installer, a second means 22 for setting up communication settings of the installer according to the received setting information; a third means 23 for downloading the application from a source of the application to the mobile terminal by utilizing the communications settings, and a fourth means 24 for installing the downloaded application.
FIG. 3 illustrates an example of an embodiment of the inventive method. At first, a first message is sent 31 from a terminal to a first server for requesting the application. The terminal may be the mobile terminal whereto the application will be downloaded or any other terminal. The inventive installer comprises the steps of receiving 32 the second message from the first server to an installer in the mobile terminal, the second message containing setting information for the installer, setting up 33 communication settings of the installer according to the setting information, downloading 34 the application from a source of the application to the mobile terminal by utilizing the communications settings, and installing 35 the downloaded application.
Since the installer may be a software application, the invention also concerns a computer program product, which has been stored on a computer readable storage media. The storage media may be a hard disk in a network server, a memory in a mobile terminal, CD-disk, etc. The product has been adapted to perform the steps of the installer, mentioned in claim 1 , when run on a computer. The computer may be a computer of a mobile terminal. As mentioned the invention makes it possible to download the same application for different utilization environments. The local installation conditions are taken into account in a setup information message from another server than the source of the application. Network, operator and service specific requirements are handled in a simple and efficient way. The setup message may contain only data for the communication settings of the installer, or it may also contain other setting information for the installer. Fur-
ther the setup message may contain data for the communication settings of the application and/or other setting information for it. The important matter is that the setup message may furthermore contain an address information wherefrom the application is downloaded and/or an address information wherefrom the application may request the desired service or other matters needed. The setup message may also be compressed, for example an entropy encoded WINZIP-file.
The invention is a sophisticated solution for operators and service providers. The providers who make applications may manufacture a single product that is useable in different situations. The service providers may utilize the product of the application providers when offering their services to customers. A possibly different provider, who handles the server wherefrom the setup messages are delivered to mobile terminals, in turn offers the inventive concept to the other providers. The installer may be pre-installed in a mobile terminal, but it can be delivered to the mobile terminal preferably in the same message that contains setup information. In this case, the installer is preferably installed before the setup information is used, since the setup information has been addressed to the installer. In the pre-installation the installer can be a separate application or a part of an operating system, such as SYMBIAN. The application to be downloaded may be a video player, and the service that the customer uses a video service. As can be noted, the invention can be formed and used for many different applications and services.
In reference to the abovementioned matters it is evident the inven- tion can be modified to a number of different solutions. For example, the setup messages can be other messages than SMS messages. Thus the invention is not restricted to the examples mentioned in this text, but it can be used in other possible realizations, in the scope of the inventive idea.
