Latest Patents
Li Ll's latest patents include "Update of a trusted name list" and "Supporting SIM toolkit applications in embedded UICCs." The first patent describes methods, devices, and servers for the as-needed update of a trusted list. In this invention, an electronic subscriber identity module (eSIM) server receives a request for an eSIM of a particular type from a wireless device. The server evaluates the request and communicates with a second eSIM server, which is not initially trusted by the secure element (SE) of the wireless device. The eSIM server sends a policy update to the wireless device, allowing the SE to update its trusted list with the identity of the second eSIM server. This process ensures that when the wireless device downloads a bound profile package (BPP) from the second eSIM server, the UICC can validate the BPP based on the updated trusted list, leading to a seamless installation of the eSIM.
The second patent focuses on enabling Subscriber Identity Module (SIM) toolkit commands to be properly routed within mobile devices that include an embedded Universal Integrated Circuit Card (eUICC). This technique involves an exchange of information between the baseband component of the mobile device and the eUICC to identify active eSIMs. The eUICC generates a list of unique identifiers for the active eSIMs, which the baseband component uses to manage and route SIM toolkit commands effectively.
