The present invention relates to a method for reducing a resource element group (REG) size, which is used at a control channel element (CCE) for a relay physical downlink control channel (R-PDCCH), for the purpose of easy interleaving by a physical resource block (PRB) unit for the R-PDCCH, and a mobile telecommunication system for the same. The mobile telecommunication system of the present invention includes reducing the CCE size to 8 REGs or less of the R-PDCCH to be included in a single PRB.

Embodiments for providing a method of controlling timing of a downlink backhaul sub-frame and a relay system for the same are disclosed. According to the present invention, a control signal is transmitted to user equipment during a control symbol period of a sub-frame and a data starting point of the sub-frame is set after a time (SG1) for switching from a transmission mode to a reception mode to receive backhaul data of a base station during a backhaul symbol period. Timing of a transmission sub-frame and a reception sub-frame is delayed by the SG1. A sum of a length of the SG1 and a time (SG2) for switching from the reception mode to the transmission mode is shorter than a length of a symbol having a normal CP. At this time, the lengths of the SG1 and the SG2 are identical to each other or the length of the SG2 is shorter than the length of the SG1. In such a case, the backhaul data are received up to a last symbol period of backhaul symbols of the reception sub-frame.

The present invention provides an admission control method in an Internet differentiated service network, for dividing an admission control function executed at an ingress edge node into a path level and a link level, performing a path level admission control function at an ingress edge node without communication with a bandwidth broker by enabling the path level to use a specific bandwidth being initially allocated to a corresponding path by a bandwidth broker, and performing a link level admission control function through the use of a measurement based admission control method by enabling the link level to be allocated a bandwidth of an unused other service using a movable boundary method when the initially allocated path level bandwidth is completely used.

A bumper beam reinforcement structure has plurality of pairs or plate insertion holes formed side by side in a longitudinal direction of a bumper beam. These insertion holes are formed on the upper surface and the lower surface of the bumper stay mounting part. Inverted U-shaped steel plates are inserted into the plurality of plate insertion holes. When an impact occurs, the deformation and the rotation of the bumper stay mounting part of the bumper beam is effectively prevented. In addition, parts such as a headlight, a corresponding panel and the like are preferably hardly damaged. Further, the cost for manufacturing the bumper beam reinforcement structure can be significantly reduced.

The present invention features a thermal management system for a hybrid electric vehicle. Such a system includes a heater core supplies heat for heating the vehicle's interior by heat exchange between a coolant and air of the vehicle's interior, a coolant line fluidly coupling an engine and heater core so the coolant being circulated by a coolant pump passes there through. A bypass valve is located in the coolant line in proximity to the engine and is selectively opened and closed according to the on/off state of the engine and so that the coolant does not pass through the engine but passes through only the heater core in the engine off state. Such a system includes a heat exchanger fluidly coupled to another heat source so the coolant is heated by the heat exchanger and supplied to the heater core when in the off state.

In the adaptive connection admission control method of the present invention, a corresponding ingress edge node performs connection admission control for a new connection within the amount of bandwidth initially allocated to each of paths between the ingress and egress edge nodes. The amount of remaining bandwidth allocated to a specific path Pr is compared with an amount of bandwidth required for a call requesting new connection setup input to the corresponding ingress edge node. The amount of additional bandwidth to be requested from the bandwidth broker is predicted when the amount of the remaining bandwidth does not satisfy the amount of bandwidth required for the connection setup requesting call. The ingress edge node requests additional bandwidth from the bandwidth broker on the basis of the predicted amount of the additional bandwidth, changing bandwidth information of the corresponding path Pr, and performing connection admission control.

A method and system for reducing transmission route of packet in Internet based nested mobile network are provided. In the method, a plurality of routers in an Internet based nested mobile network register location information using a top-level mobile router. Then, each of the mobile routers creates NEMO routing information. A packet is received through own home agent using the location information registered at the top-level router in the nested mobile network when a terminal in the outside of the mobile network transmits a packet. The receive packet is processed through the created NEMO routing information at the top-level router.

In the method for expanding an address for an Internet protocol in an Internet edge router and the record medium capable of being read through a computer having a record of a program to realize the inventive method, an address expanding system of IPv4 used by incorporating public network connection information in an IPv4 address is utilized, thereby, all services of the existing IPv4 can be accepted and an enlargement to a new service can be valid. That is, in such Internet edge router, the inventive method comprises the steps of defining public network connection information in an option class of an Internet protocol message; b) constructing a security & authentication (SA) module and an SA hierarchical protocol in a service terminal protocol in order to provide IP address information and a user authentication from a server having information of the existing public network subscribers by using the public network connection information, and constructing a connection information processing part to process the public network connection information; and c) receiving a message from a network interface and processing it, in the connection information processing part, whereby being applied to an Internet service system.
