According to one embodiment of the present disclosure, the method by means of which a mobility management entity (MME) determines the communication mode of a terminal in a communication system includes the steps of: receiving, from the terminal, an access request including information on the position of the terminal; transmitting a message to a home subscriber server (HSS) on the basis of the received access request; receiving, from the HSS, specific position information for setting a first mode; comparing the information on the position of the terminal with the specific position information; and determining the communication mode of the terminal according to the result of the comparison. According to the present disclosure, the frequent transmission of small amounts of data can be supported in an efficient manner.

Method and apparatus for efficiently transmitting small amounts of data in wireless communication systems

Provided are a method and apparatus for processing packets. A method for processing packets in a base station (ENB) may include: obtaining information on a rule for dealing with a packet according to supplementary information contained in the header of the packet; receiving a packet; extracting supplementary information from the header of the received packet; and processing the received packet on the basis of the obtained rule information and extracted supplementary information. Hence, the base station may adequately perform packet control operations in accordance with the state thereof.

Method and apparatus for applying different priorities to packets

The present invention relates to a system configuration and an apparatus for preventing the infringement of user privacy, and for collecting and analyzing information regardless of the service feature and type, while a system providing a context aware service collects and analyzes user information. The present invention discloses a method of configuring and using a context analyzer and a device profile database in order for the system providing the context aware service to collect and analyze information regardless of the service feature and type.

Method and apparatus for managing device context using an IP address in a communication system

The present invention has the aim of providing a method of an activity information notification service in which a server can receive activity information from a user of a target terminal, depending on his or her privacy setting, and then transmit the received activity information to a selected receiving user, and in which any receiving user can transmit a notification request to a target user in order to receive desired activity information. According to an embodiment of the present invention, a method of an activity information notification service at a server, the method includes steps of receiving activity information from a target terminal; determining a receiving terminal to which the received activity information will be transmitted, depending on a privacy setting of the target terminal stored in a storage unit; and transmitting the activity information to the determined receiving terminal.

The present invention relates to a method for processing information between mobile communication systems in order to prevent the degradation of user-experienced performance when different types of mobile communication networks are used. The method for processing information at user equipment (UE) to improve user-experienced performance of a mobile communication system includes performing a data communication through a first network and receiving, from a policy server, a routing policy including a validity condition which is information about a condition of designating a UE status for handover. The method further includes, in the handover, if a searched second network satisfies the validity condition, performing the data communication through the second network. Accordingly, a network for data transmission can be selected using a routing policy created in consideration of a UE status or a network status, thereby enhancing user-experienced performance.

Mobile communication system and method of information processing for improving user experience in the mobile communication system

The present invention relates to a method and apparatus for managing a Local IP Access (LIP A) connection in a local network system. The method of managing a LIP A connection of UE in a connected state according to an embodiment of the present invention includes the steps of a source home base station for UE determining a handover of the UE; when the handover of the UE is determined, determining whether a target home base station is a Long Term Evolution (LTE) release 10 or a Pre Rel-11 HeNB; and when the target home base station is a Pre Rel-11 HeNB, disconnecting the LIP A connection of the UE. According to an embodiment of the present invention, the mobility of UE having a LIPA PDN connection can be efficiently controlled in a local network where a Rel-11 H(e)NB and a Pre Rel-11 H(e)NB exist together.

Method and apparatus for supporting mobility of UE in local network

The present invention relates to a method and a device for effectively controlling a handover of a user equipment (UE) in a long connected mode. A method for controlling a handover by an eNB, according to one embodiment of the present invention, comprises the steps of: checking whether a UE is in a long connected mode; and transmitting, to the UE, channel measurement configuration information of which a channel measurement report trigger condition is alleviated compared with a normal connected mode.

The present invention relates to a method and an apparatus for transmitting contents in a mobile communication network. According to one embodiment of the present invention, the method for receiving the contents of user equipment (UE) in a mobile communication system equipped with a local server which is connected to a base station (eNB) and copies partial contents of an external content server and maintains the copied contents, can include: a content determination step of determining whether the selected contents are the contents provided from the local server when a content selection input is received; a request transmission step of transmitting a content transmission request message to the base station (eNB) when the contents are the contents provided from the local server; and a content reception step of receiving the contents from the base station. According to one embodiment of the present invention, the present invention provides the method and the apparatus for efficiently receiving the contents which reduce resources used for receiving the contents and shorten a delay time.

Method and apparatus for receiving contents in mobile communication system

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.
