Mobility optimization method, user device and access network device

Abstract

The invention discloses a mobility optimization method. The mobility optimization method comprises the steps that when UE having small data features confirms that cells supporting optimization of the small data processing capacity exist in candidate cells in the cell reselection executing process and performs cell reselection according to small data optimization cell reselection principle information. The invention further discloses another mobility optimization method. The mobility optimization method comprises the steps that a network-side provides cell reselection information for the UE normally residing in the cells and having the small data features, wherein the cell reselection information include reselection principle information including small data processing capacity factors and / or capacity information of a network supporting the optimization of the small data processing or not; target base stations having the small data processing optimization capacity and meeting the switching conditions are preferentially selected for the UE having the small data features during switching execution, and switching request messages are sent to the selected target base stations. The mobility optimization method can reduce whole-network signaling expenditure caused by small data transmission, achieve network performance optimization and improve the system efficiency.

Problems solved by technology

According to the cell reselection principle of the existing protocol, the UE with small data transmission characteristics cannot be preferentially reselected to the network that supports the optimized small data transmission mode. Therefore, in order to reduce the signaling overhead caused by small data transmission in the entire network, it is necessary to Optimizing the principle of cell reselection

Similarly, when the UE is handed over in the existing protocol, the source network cannot preferentially select the UE with small data transmission characteristics to the network that supports the optimized small data transmission mode when selecting the target network. The signaling overhead caused by this also needs to optimize the cell handover principle
