Latest Patents

Karthik's latest patents include groundbreaking work on establishing SIP sessions during Home Subscriber Server (HSS) outages. His invention allows systems to establish a SIP session even when the HSS is unavailable. This is achieved through Network Functions (NF) that perform specific steps to bypass the HSS outage. For instance, an Interrogating (I)-Call Session Control Function (CSCF) can modify a terminating message from a User Equipment (UE) to generate a modified message, which is then sent to candidate Serving (S)-CSCFs.

Another significant patent addresses the handling of SIP messages with malformed header fields. This invention outlines techniques for communication devices to identify and process SIP messages effectively. If a communication device detects that certain header fields are malformed, it can reject the SIP message, ensuring better communication reliability.
