Title:
Solution for skipping an attestation procedure between line switching fall back (CSFB), and shortening call setup time
Document Type and Number:
Japanese Patent JP6278326
Kind Code:
B2
Abstract:
A User Equipment (UE) device or network system facilitates a Circuit Switched Fallback (CSFB) procedure to enable fallback from a Long Term Evolution (LTE) network to a circuit switched domain network. A network device or a UE can operate to skill skip an authentication procedure during CSFB procedures and shorten a call setup time. A key access security management entity (KASME) is acquired. An extended service request message is communicated, or received, to originate the CSFB process from a first network of a first network device to a second network of a second network device in response to a mobile originating call or a mobile terminating call. A plurality of circuit switched (CS) key parameters is derived from the KASME, and the CSFB procedure is generated based on the plurality of CS key parameters.
