Method and an arrangement for upgrading target devices

摘要

The invention relates to a method and an arrangement for upgrading a target device via a wireless connection. Upgrade is executed by exploiting a wireless personal communications device (101) as a gateway between the content provider server (104) and the target device (102). A DRM scheme may be applied to said method for limiting the usage of transmitted content. The content may be encapsulated in a SMS or MMS message. A wireless personal communications device (101) capable of executing the presented method can be used e.g. as a personalization tool for downloadable sounds to be reproduced by a target device (102) such as a toy.
