Abstract: A catalyst which can catalyze ring-addition reaction of CO2 and an alkylene oxide at 0˜180° C. under 0.1˜8.0 MPa to produce a corresponding cyclic carbonate, and the preparation thereof. The catalyst is a conjugated microporous macromolecule polymer complexed with cobalt, chromium, zinc, copper or aluminium, and by using the macromolecule catalyst complexed with different metals to catalyze the reaction of CO2 and alkylene oxide at normal temperature and normal pressure, a yield of the corresponding cyclic carbonate of 35%˜90% can be obtained. The catalyst is easy to recover and the re-use of the catalyst has no influence on the yield; additionally, the yield can reach over 90% by controlling the reaction conditions.

Abstract: A location movement method for a self-mobile node, and a related device are provided. A self-mobile node can move to a corresponding initial to-be-assisted location range according to initial to-be-assisted location information determined by the self-mobile node or determined by a control device; and after moving to the initial to-be-assisted location range, can move to a final finely adjusted to-be-assisted location range according to finely adjusted to-be-assisted location information determined by the self-mobile node or determined by the control device, and provide an assistance service for another to-be-assisted node within the final to-be-assisted location range. Therefore, a currently existing problem is resolved: Because a precise indoor map cannot be obtained, a self-mobile node cannot move to an accurate to-be-assisted area based on an indoor map. As a result, accuracy and applicability of on-demand movement of the self-mobile node are improved.

Abstract: A method and apparatus for reducing call drop rate by validating reconfiguration messages based on service data unit (SDU) lifetime are described. A receiving device, such as a user equipment, may determine a receiving delay between receiving a first protocol data unit (PDU) and receiving a last PDU of a reconfiguration message SDU. The receiving delay may be compared with an SDU lifetime. The reconfiguration message SDU may be validated based on the comparison of the receiving delay with the SDU lifetime. A receiving delay that is greater than the SDU lifetime may indicate that the SDU is stale and, therefore, invalid. A receiving delay that is less than the SDU lifetime may indicate that the timing of the SDU is valid and the reconfiguration message SDU is to be processed. An activation time of the reconfiguration message SDU may also be honored or disregarded based on the receiving delay.
