LONG-TERM EVOLUTION CIRCUIT SWITCHED FALL BACK ENHANCEMENTS

摘要

An architecture is described that can provide enhancement with respect to circuit switched fall back. In particular, the architecture can reduce the signaling and delay of conventional systems that are necessitated by establishing a radio resource control connection prior to establishing the circuit switched fall back connection. For example, when user equipment is not in a radio resource control connected state at the time of a circuit switched fall back call, the radio resource control connection can be at least partially avoided by responding to a radio resource control connection request message with a radio resource control connection reject message that includes target cell reselection information.

1. A network device, comprising:
a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
determining that communication for a user equipment is to be switched from a packet-based network device to a circuit switched-based device, wherein the network device supports long term evolution protocols;receiving a radio resource control connection request message from the user equipment, wherein the radio resource control connection request message comprises an indication that the user equipment is not in a radio resource control connected state;in response to the radio resource control connection request message with the indication, generating a rejection message comprising first data representing another indication that the radio resource control connection request message is refused and second data representing an identity associated with the circuit switched-based network device; andtransmitting the rejection message to the user equipment.
