Abstract

The handling of emergency calls, e.g., 911 calls, should be performed on an expedited basis.
Various techniques are described herein to expedite system access to radiocommunication systems when processing an emergency call. For example, control channel locking, origination message content, and retransmission rules are modified to reduce access time.
