REDUCED HANDOVER LATENCY FOR LICENSED SHARED ACCESS

摘要

A proposed 3GPP LTE protocol enhancement disclosed herein enables an Evolved Node B (eNB) to perform a mass handoff of User Equipment from Licensed Shared Access (LSA) band spectrum to LTE Primary band spectrum without creating an over-the-air signaling surge by preventing individual handover messaging exchanges between the eNB and UEs affected by loss of LSA frequency band. A User Equipment (UE) comprises a transceiver configured to receive a broadcast paging message in a Licensed Shared Access (LSA) frequency band instructing the UE to move to a primary Long Term Evolution (LTE) frequency band from the LSA frequency band, receive system information comprising primary LTE frequency band information, extract handover parameters from the received system information for moving to the primary LTE frequency band, stop communicating on the LSA frequency band and synchronize communications with an Evolved Node B (eNB) associated with the primary LTE frequency band.
