Abstract: PURPOSE: To improve the mounting precision of a QFN (quad flat non-leaded package) having external connection terminals on the rear of a package. CONSTITUTION: In a sealed body 3 of the QFN 1, notches 8 are formed in two corners along the diagonal line direction of the surface side of the sealed body. A recognition mark 15 having a circular plate form is formed in a part of a suspension led 5b exposed from the notch 8. When the QFN 1 is mounted on a wiring board, the recognition mark 15 can be optically detected from above the sealed member 3. The recognition mark 15 is formed by removing a part of a metal plate constituting the suspension lead 5b by etching or by punching the part by a pressing machine.

Abstract: PURPOSE: A method for managing radio resources for MBMS(Multimedia Broadcast/Multicast Service) services in a mobile system is provided to prevent a waste of radio resources and a wrong operation as a system periodically informs a terminal of a state for a specific service so that the terminal can work according the service state information. CONSTITUTION: The MBMS state of a UTRAN(UMTS Terrestrial Radio Access Network) for a specific MBMS service in a null state is transferred to a PR(PReparation) state if the UTRAN receives a session start message from a CN(Core Network). In the PR state, the UTRAN notifies terminals of the associated service and executes a counting procedure to determine a radio bearer. In case that the determined radio bearer is a PTP(Point-To-Point) radio bearer, the MBMS state is transferred from the PR state to a PTP transmission state. If the determined radio bearer is a PTM(Point-To-Multipoint) radio bearer, the MBMS state is transferred to a PTM transmission state. In case that the UTRAN does not establish any radio bearer because there is no terminal to receive the service, the MBMS state is transferred to an NT(No Transmission) state.

Abstract: PURPOSE: A method is provided to simplify L2CAP(Logical Link Control and Adaptation Protocol) channel creation/configuration for a node. CONSTITUTION: To establish a connection for a node, a connect request is sent(300). A connect response is received(302). The connect response provides information to determine if the connection is successful(304), is pending(306), or is refused(308). If the connection is successful, a range of acceptable parameter values are received from the node(310). An L2CAP channel begins with the L2CAP layer sending the remote L2CAP layer a configuration request(312). The L2CAP layer receives a configuration response from the remote L2CAP layer(314). A remote configuration request is received from the remote L2CAP layer(316). The L2CAP layer sends the remote L2CAP layer a remote configuration response(318). Once the L2CAP channel has been configured, the L2CAP channel is open(320). Data is read and written. The L2CAP channel is disconnected(322) when a loss of the HCI link occurs, when the remote node disconnects the L2CAP channel, or when the node disconnects the L2CAP channel.
