Title:
METHODS, DEVICES AND COMPUTER READABLE MEDIA FOR SIMULTANEOUS CONNECTIVITY BASED HANDOVER
Document Type and Number:
WIPO Patent Application WO/2021/022426
Kind Code:
A1
Abstract:
A method for simultaneous connectivity based handover is performed at a network device as a target network device (130) of handover. In the method, a handover request message (101) is received from a source network device (120), the handover request message containing transmission capability of a terminal device (110) to be handed over. Based on information contained in the handover request message, transmission capability coordination is performed to determine transmission parameter configuration for the target network device and a transmission capability coordination result. A handover response message (102) is then transmitted to the source network device, to inform the source network device of the determined transmission parameter configuration for the target network device and the transmission capability coordination result.
