摘要： The present invention relates to a wireless communication system and a method for managing a cache server in the wireless communication system, the invention includes a step for checking a regional cache server to transmit contents when a DNS (Domain Name System) request a message for receiving contents acquired from a terminal, and a step for transmitting the contents by the cache server according to a contents request message received from the terminal. These steps can prevent the same data from being transmitted several times through a wireless communication network. Therefore, network usage associated with the service is reduced, and the network can be used more efficiently.

摘要： A method and apparatus for providing a local IP access service to a User Equipment (UE) attached to a femtocell including a Packet Data Network (PDN) gateway function in a wireless communication system. A method includes receiving a service request from a User Equipment (UE), transmitting an initial UE message including information on a local gateway to a Mobility Management Entity (MME), storing bearer information carried in an initial context setup request transmitted by the MME, receiving a Packet Data Network (PDN) connectivity request from the UE, forwarding the PDN connectivity request to the MME, receiving a create session request from the MME, and establishing a radio bearer with the local gateway, the local gateway being co-located with the femtocell.

摘要： A method for controlling device triggering in a mobile communication system includes registering a default urgent level of a terminal when the terminal is connected, receiving a device trigger register including urgent level information transmitted from an application server, and setting the received urgent level in a packet filter, and comparing, upon reception of a downlink data packet from the application server, a default urgent level and an urgent level of the application server to determine whether to transmit a downlink data notification. The method further includes receiving a device trigger register including wait time information transmitted from an application server, and then setting the received wait time in the packet filter, and buffering during the wait time upon reception of the downlink data packet from the application server, and then determining a downlink data notification transmission upon expiration of the wait time.
