1. Field of the Invention
The present invention relates to a mobile telecommunication terminal, and more particularly to a method for changing a performance controlling parameter for a mobile telecommunication terminal using a short message service (SMS).
2. Background of the Related Art
The short message service (SMS) was developed by taking advantage of the digital architecture of modern mobile telecommunication networks. Specifically, digital data can be transmitted throughout the mobile telecommunication network. The SMS allows for transmission of characters, such as numbers, letters, and other symbols, in the form of a short message. Thus, a user can send and receive a short sentence of 80-160 bytes using a mobile communication terminal, without requiring additional equipment.
Usage of SMS has increased dramatically in recent times, as greater numbers of people have begun using mobile communications. Unlike e-mail, an SMS message is transmitted to a recipient almost instantaneously upon its being sent. Hence, SMS has become firmly rooted as a means of telecommunication. Additionally, various information services employ SMS to transmit information such as weather forecasts, news reports, and stock market information. Moreover, the SMS message can include both an origination number and a message.
Usage of SMS has also expanded into the realm of electronic commercial transactions and/or electronic settlements. For example, SMS can be used with credit card companies to transmit transaction approval content to a mobile telecommunication terminal. Among other benefits, such a commercial use can prevent unauthorized credit card transactions.
An operation of the SMS system will next be described. First, a short message that has been transmitted by a user through the mobile telecommunication terminal 1 is transmitted to the exchanger 3 through the base station 2. The exchanger 3 certifies that the transmitted message is an SMS message and transmits it to the message center 4. The message center 4 determines to where the message has to be transmitted by using a destination telephone number of the short message and thereby performs a routing.
The SMS provided through the above system is typically transmitted using either a point-to-point service or a broadcasting service.
Point-to-point service is a service for sending a short message to a user of a specified mobile telecommunication terminal to which reliable transmission is possible. That is, the message center checks a state of the destination mobile telecommunication terminal and completes a transmission of the short message according to the determined state.
Broadcasting service is a service for sending a short message to each of a plurality of mobile telecommunication terminals in a group. The group can be established in any manner, such as based on region information or subscription information. In the broadcasting service, since the short message is simultaneously transmitted to the group of users, if a given user turns the power of the mobile telecommunication terminal off or if the user's line is busy, the corresponding short message will not be received.
The related art system and method have various problems, For example, the related art mobile telecommunication terminal has to be upgraded by off-line A/S in order to control special performance features or to change a parameter used to realize the performance.
That is, in order to change the parameter which controls the performance of the mobile telecommunication terminal, the entire software has to be upgraded. Also, when the performance is required to be changed by the mobile telecommunication provider or the mobile telecommunication terminal provider, the user has to visit an agent or a customer service center to receive the off-line A/S.
The above references are incorporated by reference herein where appropriate for appropriate teachings of additional or alternative details, features and/or technical background.
An object of the invention is to solve at least the above problems and/or disadvantages and to provide at least the advantages described hereinafter.
Another object of the present invention is to provide a system and method for changing a performance controlling parameter of a mobile telecommunication terminal on-line through a SMS.
In one preferred method for changing the performance controlling parameter of a mobile telecommunication terminal, the parameter of the mobile telecommunication terminal is changed by using an SMS message including a parameter relevant to the performance controlling of the mobile telecommunication terminal and a password for a certification with a destination mobile telecommunication terminal.
According to another preferred embodiment, a value for changing the performance controlling parameter is preferably included to a special field among short message formats of the mobile telecommunication terminal.
According to another preferred embodiment, a method for changing a performance controlling parameter of a mobile telecommunication terminal, including receiving a short message service (SMS) message, including a password of a mobile telecommunication terminal and a performance controlling parameter of the mobile telecommunication terminal to be changed, storing the performance controlling parameter in the mobile telecommunication terminal, and applying the performance controlling parameter to the mobile telecommunication terminal.
According to another preferred embodiment, a method for changing a performance controlling parameter of a mobile telecommunication terminal, including receiving a short message service (SMS) message by the mobile telecommunication terminal, wherein a value for changing the performance controlling parameter is included as a special field among SMS message formats of the mobile telecommunication terminal, and including the performance controlling parameter as a parameter of the mobile telecommunication terminal.
According to another preferred embodiment, A short message service (SMS) message including a CHARi field, configured to contain a performance controlling parameter value to be provided to a mobile communication terminal to modify an operation of the mobile telecommunication terminal, and a MSG-ENCODING field, to indicate a kind of code used in the CHARi field.
To achieve at least the above objects in whole or in parts, there is provided a method for changing a performance controlling parameter of a mobile telecommunication terminal including receiving a short message including a password of the mobile telecommunication terminal and a performance controlling parameter to be changed, storing the performance controlling parameter in the mobile telecommunication terminal, and applying the performance controlling parameter to the mobile telecommunication terminal.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objects and advantages of the invention may be realized and attained as particularly pointed out in the appended claims.
The invention will be described in detail with reference to the following drawings in which like reference numerals refer to like elements wherein:
Reference will now be made to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
The preferred embodiments provide a system and method to change parameters which control a performance of a mobile telecommunication terminal by an SMS message. Thus, when the performance of a mobile telecommunication terminal is required to be changed, for example, due to a change of the mobile telecommunication system or when the performance controlling parameter is required to be changed by the mobile telecommunication provider or the mobile telecommunication terminal manufacturer, a corresponding parameter of the mobile telecommunication terminal is preferably changed on line using an SMS message. At this time, a related art type SMS message is used as much as possible, and only necessary several types are defined newly.
As shown in
That is, when a user edits a prescribed message, an SMS tele-service layer transmits values having additional attributes with the message inputted by the user to the SMS transmission layer. The SMS transmission layer adds a destination address and information about whether a response is required or not to the SMS transmission layer, and provides the message to a SMS intermediate layer. A message transmitted from the SMS transmission layer to the SMS intermediate layer is called a transmission layer message. As above, the transmission layer message transmitted to the SMS intermediate layer is transmitted to the base station 15 through a link layer.
In this example, a wireless messaging tele-service corresponding to a related art tele-service and an SMS point-to-point service among transmission layer message types are used in the short message according to this preferred embodiment. It should be understood that other alternatives could be used.
SUBPARAMETER_ID is a sub-parameter identifier and this field is preferably set as ‘00000001’. SUBPARAM_LEN is a length of the sub-parameter, which is expressed as 8 bits, except the SUBPARAMETER_ID and the SUBPARAM_LEN. MSG_ENCODING denotes a kind of a message encoding. For example, ‘00000’ indicates an octet and ‘10000’ indicates Korean. NUM_FIELDS denotes a length of CHARi field, and the CHARi includes letters corresponding to a message.
In the user data format, if the MSG_ENCODING field is the octet (‘00000’) and the first octet of the CHARi is a special letter byte (e.g. 0×00), which preferably indicates a parameter change, contents corresponding to the parameter change of the mobile telecommunication terminal are included as formats of
The SUBPARAMETER_ID of
A password is preferably provided to prevent anyone except an authorized person from gaining access to the parameter change of the mobile telecommunication terminal. Accordingly, when the mobile telecommunication terminal receives a short message relevant to the parameter change of the mobile telecommunication terminal, a certification process is preferably performed using the password.
The SUBPARAMETER_ID of
First, a parameter to be changed is inputted to the short message format of the mobile telecommunication terminal, thereby setting the change parameter (step S1). Additionally, a password for certifying the corresponding mobile telecommunication terminal at the time of the parameter change may also be provided at this time. The password not only limits access to a prescribed user to perform to the parameter change, but also determines whether the mobile telecommunication terminal that transmitted the short message is a mobile telecommunication terminal of which a parameter has to be changed. That is, since each mobile telecommunication terminal is provided with its own password, when the performance controlling parameter of the special mobile telecommunication terminal is changed, a password corresponding to the mobile telecommunication terminal is preferably transmitted with the short message.
The SMS point-to-point message, including the changed parameters, is then transmitted to a prescribed mobile telecommunication terminal (step S2). Then, the corresponding object mobile telecommunication terminal extracts the password inputted to the performance controlling password field of the received SMS message and certifies the password (step S3).
Next, it is determined whether the password is correct (step S4). If the password inputted to the performance controlling password field is identical to that set in the receiving mobile telecommunication terminal, the SMS message including the performance controlling parameter is received by the object mobile telecommunication terminal. The performance controlling parameters transmitted through the SMS message are then stored in a corresponding memory address of the mobile telecommunication terminal (step S5).
A new parameter stored in the memory is then applied to the current mobile telecommunication terminal as is, or is applied after the mobile telecommunication terminal is rebooted (step S6).
If, however, the password is not identical to that of the mobile telecommunication terminal, it is determined that the mobile telecommunication terminal should not receive the short message. The short message is thereby abandoned (step S7).
The system and method for providing a performance controlling parameter as described herein has many advantages. For example, as a method for changing the performance controlling parameter of the mobile telecommunication terminal, both the SMS point-to-point service and the broadcasting service which controls a performance at a time by using a broadcasting message for the mobile telecommunication terminal having the same parameter change software therein are possible.
Also, when a recall is required after determining that a mobile telecommunication terminal has a problem in the performance controlling part, an entity such as the mobile telecommunication terminal manufacturing company can change the performance controlling parameter through the short message. The performance controlling error of the mobile telecommunication terminal can thus be easily removed without requiring off line service.
Accordingly, in the method for changing the performance controlling parameter of the mobile telecommunication terminal according to the preferred embodiment, the parameters relevant to controlling the performance of the mobile telecommunication terminal can be changed through the short message, thereby enabling on-line A/S and reducing a cost generated by off-line A/S.
Moreover, in the method for changing the performance controlling parameter of the mobile telecommunication terminal according to the preferred embodiment, the parameters relevant to controlling the performance of the mobile telecommunication terminal can be upgraded even when the user cannot recognize the need, or even without the user taking action, thereby improving the user's convenience and reducing a management cost for the mobile telecommunication terminal, for example by the manufacturing company.
The foregoing embodiments and advantages are merely exemplary and are not to be construed as limiting the present invention. The present teaching can be readily applied to other types of apparatuses. The description of the present invention is intended to be illustrative, and not to limit the scope of the claims. Many alternatives, modifications, and variations will be apparent to those skilled in the art. In the claims, means-plus-function clauses are intended to cover the structures described herein as performing the recited function and not only structural equivalents but also equivalent structures.
