摘要:
Provided is a subframe scheduling method in which a relay may transmit interval information of a service to a base station, and the base station may modify a location of a subframe based on the interval information, and thereby preventing a quality deterioration occurring due to a retransmission failure. The subframe scheduling method may include: setting and transmitting, by a base station, subframe information; setting and implementing, by a relay, a service based on the subframe information; transmitting, by the relay, interval information of the service to the base station; modifying, by the base station, the subframe information based on the interval information; and transmitting, by the base station, the modified subframe information to the relay.

A method of controlling femtocell interference considering a macrocell is provided. The method of controlling the interference includes a method of setting transmission power of the femtocell and methods of avoiding the interference of the femtocell. The methods of avoiding the interference include a PRB rotation method, a PRB transmission power restriction method, a hybrid method and a UB rotation method. The method of setting the transmission power and the methods of avoiding the interference may be implemented independently or implemented in combination with each other. Hence, according to the present invention, the femtocell itself can control the interference without affecting an interface of an existing macrocell base station and without signaling through the interface with the macrocell.

Provided is a method of managing mobility of a user equipment. The method includes: establishing by a first base station a communication with the user equipment; transmitting by the first base station a Coordinated Multiple Point (CoMP) addition request to a second base station; establishing by the first and second base stations a CoMP communication with the user equipment according to the CoMP addition request; transmitting by the first base station an anchor cell change request to the second base station; and operating the second base station as an anchor cell of the CoMP communication according to the anchor cell switch request.

The present invention relates to the method and data sharing system which establishes an access right for data to share in pure or hybrid P2P environment and thus decides to open and share the data in accordance with which whether a recipient peer has the access right or not, thereby protecting the data from the access of the unspecified public and preventing the data from spreading in an improper manner. Also, since the existence of the data is not open to recipients with no having access right, the method and data sharing system according to the present invention has an effect of protecting the copyright and privacy of a data provider.
摘要:
The present invention relates to a mobile communication system and a tunnel management method thereof. In the tunnel management method, tunnel information update request having a user equipment identifier of the user equipment is received at a serving gateway from a mobility managing device when the user equipment performs handoff. Then, tunnel information is updated by changing address information of data destination for all tunnels having the user equipment identifier.
