Latest Patents
One of Groen's latest patents is a roaming gateway enabling location-based services (LBS) roaming for user planes in CDMA networks without requiring the use of a mobile positioning center (MPC). This innovation allows LBS support to CDMA mobiles while roaming on another network. The invention routes IS-801 session data by a routing gateway to the correct visited network PDE, which contains the necessary BSA data to return assistance data to an interrogating mobile device. Additionally, Groen has developed a standalone exemplary roaming LBS routing gateway (XRG) that provides network connectivity between PDE equipment in multiple carrier networks. This invention implements a roaming LBS gateway to facilitate roaming between CDMA carriers that utilize a PDE for this purpose, as an MPC is typically an optional network node according to LBS specifications.
Another significant patent involves a wireless network location-based reference information service. This invention provides a '411xx' value-added service to wireless users, allowing them to obtain quick and accurate information about their current geographic location. Users can access information about nearby services, such as stores, libraries, and gas stations, through a mobile-terminated short message system (SMS) message. Upon receiving a 411xx call, the MSC generates an ORREQ/TCAP trigger based on the requested service, ensuring that users receive timely assistance.
