CIRCUIT SWITCHED FALLBACK HANDOVER METHOD AND APPARATUS, AND BASE STATION

摘要

The present invention discloses a CSFB handover method and apparatus, and a base station, and belongs to the communications field. The method includes: receiving, by an base station, a CSFB indication; sending, by the base station after receiving the CSFB indication, a measurement control message to user equipment, where the measurement control message is used to instruct the user equipment to measure cell signal quality and send a corresponding event measurement report; and according to a receiving status of the event measurement report sent by the user equipment, selecting, by the base station, to complete CSFB handover by using blind handover, or selecting to complete CSFB handover by using measurement-based handover. In the present invention, according to a receiving status of an event measurement report sent by user equipment, blind handover is selected or measurement-based handover is selected to complete CSFB handover, thereby increasing a CSFB handover success probability.

主权项

1. A circuit switched fallback (CSFB) handover method, comprising:
receiving, by a base station, a CSFB indication indicating that user equipment is handed over from an Long Term Evolution (LTE) cell to a 2G/3G cell to perform a circuit switched (CS) service, wherein a site of a base station serving the LTE cell is the same as a site of a base station serving the 2G/3G cell; sending, by the base station after receiving the CSFB indication, a measurement control message to the user equipment, wherein the measurement control message is used to instruct the user equipment to measure cell signal quality and send a corresponding event measurement report; and according to a receiving status of the event measurement report sent by the user equipment, selecting, by the base station, to complete CSFB handover by using blind handover, or to complete CSFB handover by using measurement-based handover.
