Abstract: The present invention is to provide a stator for external rotor type motor, enabling to manufacture a motor with a high viscosity rate by allowing a unit tooth of a stator to be partially separated from an adjacent tooth. In order to accomplish the object of the present invention, there is provided a stator for external rotor type motor, comprising: a unit yoke; and a plurality of unit modules including a unit tooth extensively formed on the unit yoke, wherein the plurality of unit modules is continuously formed in a ring shape, and the unit yoke includes a connection part connected to an adjacent unit yoke, and a dividing part separated from the adjacent unit yoke, and one unit module in the plurality of unit modules is mutually separated from the adjacent unit module by a cutting part.

Abstract: Provided is a method of resource management and call admission control in an access network in a hierarchical manner.

Abstract: A method of allowing a network communication service user (subscriber) to receive a desired network communication service with a constant (the same) quality regardless of being in a wired or wireless communication environment based on a single service level agreement (SLA) of the subscriber is provided.
