Description:
The present application claims priority from U.S. Provisional Patent Application No. 60/629,300, filed on Nov. 19, 2004, the content of which is hereby incorporated by reference into this application. 
    
    
     BACKGROUND OF THE INVENTION 
     Wireless network operators typically compete for customers based upon cost of services. Customers can obtain discounts by signing multi-year contracts with a wireless network operator. Once a multi-year contract expires, a customer typically signs a new agreement with the same wireless network operator in order to maintain the same wireless telephone number. 
     The FCC has recently mandated local number portability. Local number portability allows customers to sign up for service with a new wireless network operator while maintaining the same wireless telephone number. However, there are still impediments for customers when switching wireless network operators. For example, after using a wireless telephone for a period of time, a customer has typically programmed a large number of contact information into their existing wireless telephone. In order to maintain customer loyalty, wireless network operators may provide services which allow the customer to transfer this contact information into a new wireless telephone provided by the same network operator. Due to the number of different wireless network standards, it is more difficult for a competing wireless network operator to offer the same service. 
     SUMMARY OF THE INVENTION 
     Systems and methods for subscriber identity module (SIM) card data transfer are provided. In accordance with exemplary embodiments of the present invention, a wireless telephone downloads software which can convert data from a format of a first SIM card to a format of a second SIM card. 
     Other objects, advantages and novel features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Although there are a number of different wireless network standards, some standards are more compatible with each other than others. For example, an iDEN network, such as that owned and operated by Nextel Communications, Inc. of Reston, Va., operates using a protocol based on those used in GSM networks. However, there are a number of differences between the protocols and other operational features employed in iDEN and GSM networks. For example, while both iDEN and GSM wireless telephones employ a subscriber identity module (SIM) card, the formatting of the data between the two networks is different. Accordingly, while a SIM card from a GSM wireless mobile unit, such as a wireless phone, can be physically inserted into an iDEN wireless mobile unit, the data stored on the GSM SIM card cannot be used by the iDEN wireless mobile unit. 
     One technique for transferring data from a GSM SIM card to an iDEN SIM card requires the iDEN wireless network operator to transfer the data. Specifically, a customer brings a GSM SIM card to an iDEN network operator&#39;s retail store or service center and a representative of the iDEN network operator transfers the data from the GSM SIM card to an iDEN SIM card. However, this requires the customer to take the time to travel to the iDEN network operator&#39;s retail store or service center, which a customer may consider to be inconvenient. Additionally, this procedure increases the operating expense of the wireless network operator because this procedure requires the wireless network operator&#39;s personnel to perform this manual transfer of data. 
     In accordance with exemplary embodiments of the present invention, a customer can transfer data from a GSM SIM card to an iDEN SIM card without requiring a visit to a wireless network operator&#39;s retail store or service center. According to exemplary embodiments of the present invention, wireless mobile unit client software for transferring data from a GSM SIM card to an iDEN SIM card is stored in a wireless network operator&#39;s network, for example, in an over-the-air provisioning (OAP) server. The software can be downloaded to a customer&#39;s wireless mobile unit, thereby allowing the customer to transfer data from a GSM SIM card to an iDEN SIM card. 
     The sole FIGURE illustrates an exemplary method for transferring data from a GSM SIM card to an iDEN SIM card. A customer, who is a former GSM user, buys an iDEN phone and wants his data transferred from the GSM SIM card to the iDEN SIM card in his new phone, which is now otherwise ready for normal operation in the iDEN mode (step  105 ). The user downloads wireless telephone client software over-the-air from the carrier&#39;s network server (step  110 ). The user then activates the downloaded client software (step  115 ). The client software then queries, via the user interface (UI), whether the user wants to now transfer the GSM data to the iDEN SIM card (step  120 ). If an acknowledgement of transfer request is not made, then the phone reverts back to normal operation. If the confirmation is made, then the client software asks the user to turn off the phone and subsequently replace the current SIM card (provisioned iDEN SIM) with the old GSM SIM card and subsequently turn the phone back on (step  125 ). When the GSM SIM card is inserted in the phone, the client software copies all the GSM data onto the phones internal memory (step  130 ). In the next phase, the user is asked to turn off the phone after the GSM data has been copied into the phone&#39;s internal memory then and to replace the GSM SIM card with the iDEN SIM card (step  135 ). The downloaded telephone client software then copies the data stored in the phone&#39;s memory onto the iDEN SIM card (step  140 ). 
     Upon completion of the copying process, the user is now equipped with all personal data from the old GSM SIM card and, because the client software is configured for a one time use, it will then delete itself from the phone&#39;s memory in order to free up memory space ( 145 ). The phone then reverts back to its normal operation ( 105 ). 
     Although the present invention has been described above in connection with transferring data from a GSM SIM card to an iDEN SIM card, the present invention is equally applicable to the transfer of data from an iDEN SIM card to a GSM SIM card. Moreover, the present invention is also applicable to the transfer of data between any two types of memory cards for different wireless mobile units and networks. And, although the present invention has been described above in connection with wireless telephones, the present invention can be used for any type of wireless device, including wireless personal digital assistants (PDAs), wireless pagers, wireless e-mail stations, and the like. 
     Moreover, while the invention has been described in connection with various embodiments, it will be understood that the invention is capable of further modifications. This application is intended to cover any variations, uses or adaptations of the invention following, in general, the principles of the invention, and including such departures from the present disclosure as known, within the known and customary practice within the art to which the invention pertains. 
     The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
