Problems solved by technology

thus limiting the usability of the Scell
Furthermore, it should be noted that in existing mobility schemes, when UE moves through an area with high density of small cells, a lot of signaling between eNB and UE and between eNB of Pcell and eNB of Scell ​​may be triggered
As mentioned above, this not only causes latency, but also increases the signaling load, which can be very expensive

Abstract

A mechanism is provided for controlling the autonomous movement process of user equipment. A list of candidate communication cells that can be used as target cells for an autonomous mobility procedure performed by the UE is sent to the UE through the network. In addition, when the list is sent to the communication unit, preparation information is sent to the candidate communication cells included in the list sent to the user equipment, the preparation information being used to prepare candidate communications for a possible autonomous communication process performed by the user equipment. community. When a cell is detected, the user equipment utilizes this list to determine whether the detected cell is a candidate cell for autonomous mobility procedures. When the cell receives an access request, it uses the preparation information to determine that the requesting UE is undergoing an autonomous mobility process, and obtains configuration data for immediately providing services to the user equipment.
