Latest Patents

One of his latest patents is a "Preferred carrier selection method." This invention involves a method and apparatus for selecting a cellular carrier frequency for accessing cellular airtime services based on a list of preferred system identification codes (SIDs). The cellular telephone is programmed to store a list of preferred SIDs corresponding to preferred carriers. When any SID remains in the preferred list, the standard A/B system selection function is replaced by a substitute system selection function. This function includes three carrier selection modes: Home Only mode, SID Only mode, and Roam Saver mode. The Roam Saver mode prioritizes service through a home carrier and then through a carrier broadcasting a matching SID from the preferred list. Importantly, it never denies service to emergency or non-emergency destinations if any SID is detected. Status indicators are utilized to differentiate between various service availability scenarios. Additionally, the system supports multiple number assignment modules (NAMs) to accommodate subscriptions from various carriers, allowing users to manually select or automatically choose the appropriate NAM.
