Abstract: Methods are provided for effectively accessing and managing open applications on a mobile device. In response to an End key key-press event, an open application is terminated and another open application is promptly maximized. In an embodiment, another key may be pressed to access to an Applications Menu which indicates open applications. Open applications can be selected on the Applications Menu and selectively maximized or terminated. In an embodiment a key may be pressed to access an Open-Applications Menu which lists open applications. Open applications can be selected on the Open-Applications Menu and selectively maximized or terminated.

Abstract: A roaming gateway interfaces between a CDMA MSC and a GSM core infrastructure, so that a GSM-enabled CDMA mobile station having a subscription in the GSM system can roam into the CDMA system and be authenticated to use the CDMA system. The roaming gateway obtains necessary authentication information from the GSM system and transfers the information to the mobile station using a short message service.
