Patent number: 9277392Abstract: A method and apparatus for a micro Base Station (BS) to provide a terminal with communication service in a wireless communication system are provided. The method includes forwarding, in the micro BS, an attach request message received from the terminal to a local Mobility Management Entity (MME), determining, at the local MME, whether the terminal has performed at least one of authentication and registration processes, transmitting, at the MME, to a local registration processor a service provision check request message asking for whether the terminal is registered with the communication service to a local registration processor, and providing the terminal with the communication service in response to a service provision check acknowledge message accepting the attach request which is received from the local registration processor and no communication service in response to the service provision check acknowledge message rejecting the attach request which is received from the local registration processor.Type: GrantFiled: July 29, 2010Date of Patent: March 1, 2016Assignees: Samsung Electronics Co., Ltd., Kyung Hee University Industry Academic Cooperation FoundationInventors: Sung Won Lee, Han Na Lim, Beom Sik Bae

Patent number: 9179443Abstract: The present relates to a method for providing a terminal with a service in a mobile communication system which includes transmitting to mobility management entity an attach request message for initiating registration of the terminal having a virtual IP address with the mobile communication system; registering, at the mobility management entity, location of the terminal with a home subscriber server; and completing the registration by transmitting an attach accept message from the mobility management entity to the terminal. The present invention is capable of registering a terminal with a mobile communication system initially without bearer path and IP address allocation and, when a packet address to the terminal occurs, allocating the radio resource, bearer resource, and IP address through paging procedure, thereby proving the UE with the service.Type: GrantFiled: August 9, 2011Date of Patent: November 3, 2015Assignees: Samsung Electronics Co., Ltd., Kyung Hee University Industry Academic Cooperation FoundationInventors: Sung Won Lee, Han Na Lim, Beom Sik Bae
