Publication number: 20110141972Abstract: A Transport Network Layer (TNL) connection setup method for a base station includes monitoring Physical Cell Identity (PCI) values of neighboring cells. When it is monitored that the PCI values are changed, IP addresses of neighboring base stations corresponding to the changed PCI values are acquired. Thereafter, it is determined whether it is necessary to perform a new TNL connection setup with respect to other neighboring base stations, based on the changed PCI values and the acquired IP addresses. When it is determined that it is necessary to perform the new TNL connection setup, the TNL connection setup is performed with the acquired IP addresses.Type: ApplicationFiled: August 3, 2010Publication date: June 16, 2011Applicant: Electronics and Telecommunications Research InstituteInventors: Sang Chul OH, Seung-Que LEE, Hyung Deug BAE, Jun Sik KIM, Nam Hoon PARK

Patent number: 7821961Abstract: A terminal including a packet detecting unit, a user input/output unit, a CID managing unit, and a data storing unit is disclosed. The packet detecting unit determines whether a packet can be classified by a pre-established packet classification rule or a packet cannot be classified by the rules. For packets that cannot be classified, the user input/output unit receives QoS information from a user. The CID managing unit generates a new packet classification rule for the unclassified packet, checks a CID in a data storing unit, the CID having the same QoS class as that of the QoS parameter input through the user input/output unit, and determines whether to generate a new CID or to add the new packet classification rule to the pre-established CID. The data storing unit storing unit Stores the new packet classification rule generated by the CID managing unit and information on the CID.Type: GrantFiled: October 10, 2006Date of Patent: October 26, 2010Assignees: Samsung Electronics Co., Ltd., Electronics and Telecommunications Research Institute, KT Corporation, SK Telecom Co., Ltd, Hanaro Telecom, Inc.Inventors: Hyung-Deug Bae, Nam-Hoon Park, Jee-Hwan Ahn
