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.
