Abstract: Disclosed are a polyethylene microporous film and a method of preparing the same. The polyethylene microporous film, which has a laminated structure comprising B layer/A layer/B layer, prepared by melt-mixing a polyethylene and an aliphatic hydrocarbon solvent together at controlled mixing ratios to separately form an A layer and a B layer having different porosities, and then coextruding the A and B layers, thus exhibiting excellent mechanical properties, such as strength and elongation, and high-temperature stability. Therefore, the polyethylene microporous film is suitable for use in a rechargeable battery separator.

Abstract: A method for generating multimedia events such as images and/or sound in a mobile station uses a Short Message Service (SMS) or the like. According to a preferred embodiment of the present invention, a short message service center sends the data corresponding to the multimedia event selected by an originating mobile station only after the SMC makes sure that there is no data corresponding to the selected event in a receiving mobile station. A new teleservice, Multimedia Teleservice, is added to the SMS transport layer, and the User Data in the teleservice layer located under the transport layer now includes CHARi field or the like. The CHARi field performs control of the data transmission by supplying control fields including a multimedia event index and data fields in the user data.
