  • Paging optimization
    Patent number: 11889470
    Abstract: Methods and systems for providing paging optimization are described. In one embodiment, a method for processing a paging request in a wireless network system includes sending, by a User Equipment, a Physical Random Access Channel (PRACH) preamble; receiving, by the UE, a paging request; receiving, by the UE, a Random Access Response; sending, by the UE, a response with the response having a cause labeled as a paging response in place of an Radio Area Network (RAN)-based Notification Area (RNA) update response; receiving, by the UE, an RRCResume message; sending, by the UE, an RRCResume Complete message; and sending, by the UE, a paging response.
    Type: Grant

  • Mitigating drawbacks of ciphering failures in a wireless network
    Patent number: 10477394
    Abstract: A wireless communication device communicates with a GPRS wireless network where ciphering has gone out of sync between the wireless communication device and the wireless network. The wireless communication device triggers an authentication procedure that re-synchronizes the ciphering. Following the trigger, the wireless communication device and the wireless network continue the authentication procedure so that ciphering parameters can be negotiated again and data communication can resume.
