METHOD OF CHANGING UE MOBILITY STATE IN RRC CONNECTED MODE

摘要

In a wireless communication system, a user equipment is configured to establish an RRC link with a cell when operating in a first mobility state or a second mobility state of an RRC connected mode. When all currently running application programs only cause background traffic or do not require short data latency, the user equipment is configured to maintain in or switch to the first mobility state having a lower monitoring frequency. When any of the currently running applications involves user interaction or requires short data latency, the user equipment is configured to maintain in or switch to the second mobility state having a higher monitoring frequency.

1. A method of changing a user equipment mobility state based on background traffic, comprising:
a user equipment establishing a first radio resource control (RRC) link with a cell when operating in a first mobility state of an RRC connected mode; the user equipment sending a first message to the cell when the user equipment remains operating in a background mode longer than a predetermined period of time after having established the first RRC link; and the user equipment switching from the first mobility state to a second mobility state of the RRC connected mode when the user equipment is able to receive a second message from the cell before a first timer expires, wherein:
the first message is associated with changing the user equipment mobility state;the second message is associated with approving a change of the user equipment mobility state;a first monitor frequency of the user equipment when operating in the first mobility state is higher than a second monitor frequency of the user equipment when operating in the second mobility state; andall application programs run on the user equipment are non-user interactive when the user equipment operates in the background mode.
