Abstract:
The present invention relates to a method of acquiring an additional wireless resource for transmitting data to a user in a wireless communication system such as long term evolution (LTE) using a Non-3GPP access network such as WLAN, thereby improving network performance and quality of experience by the user. In the present invention, the provided method may collect information related to the dynamically changing WLAN using a UE and may provide quick and correct status information containing a congestion status of the WLAN to the UE, thereby enhancing the experience of service quality compared with existing technologies. In addition, the present invention proposes a method that may prevent a number of UEs from moving to access a network at once and adjust the frequency of the confirmation processes to check whether access to the networks are available for traffic transmission. Furthermore, the present invention proposes a method of using an indicator capable of presenting the congestion status of the WLAN more accurately.
Abstract:
PURPOSE: A communication system and a push service providing method in the communication system are provided to provide an effective push service in which various push service providers exist. CONSTITUTION: An application server requests server registration from a push server (230). The push server requests the server registration from a common certificate server (240). The push server receives server registration confirmation from the common certificate server. When a message for a push service is triggered, the application server requests push from the push server. The push server transmits push notification according to the push request to a terminal.

Abstract:
PURPOSE: An apparatus for performing authentication in a mobile communication system and a method thereof are provided to enable an authentication process in an EPS(Evolved Packet System) in case of HSS(Home Subscriber Server) overload, thereby stably providing the service to a UE(User Equipment). CONSTITUTION: A MME(Mobility Management Entity)(220) detects HSS(230) overload in step 211. The MME transmits a common default subscription data request message to an AC(Authentication Center)(240) in step 213. The AC transmits a common default subscription data response message as a response message to the common default subscription data request message in step 215. The MME switches from an operation mode to an overload mode in step 217. A UE(210) transmits an attach request message to the MME in order to connect to a network in step 219. The MME transmits an alternative authentication data request message to the AC in step 221. The AC derives an alt_k as a security key using IMSI(International Mobile Subscriber Identity) of the UE included in the alternative authentication data request message and an alternative key stored in advance, and derives an XRES(Expected Response)' value using the alt_k in step 223. The AC transmits an alternative authentication data response message as a response message to the alternative authentication data request message to the MME in step 225. After receiving the alternative authentication data response message from the AC, the MME transmits a user authentication request message for requesting a user authentication to the UE in step 227. The UE derives an alt_k and RES(Response)' value using the alternative key stored in advance in step 229. The UE transmits a user authentication response message as a response message to the user authentication request message to the MME in step 231. The MME checks whether the RES' value included in the user authentication response message is the same with the XRES' value included in the alternative authentication data response message in step 233. The MME transmits an attach reject message to the UE when the said values are not identical in step 235. The MME transmits an attach accept message to the UE when the said values are identical in step 237.

Abstract:
PURPOSE: A mobile communication system and an information processing method are provided to determine the transmission of traffic by considering a state of an access network or UE(User Equipment). CONSTITUTION: A UE executes IP(Internet Protocol) communication by using an access network 1(300). A policy server transmits a routing policy to the UE by generating a routing policy according to a service provider policy(302). The UE searches for an access target network in handover and confirms user state condition information including routing standards(304). If an access network 2 satisfies with the user condition information, the UE executes data communication by using the access network 2(306).

Abstract:
PURPOSE: A controlled interference mitigation maintenance method in a multiple layers network is provided to reduce real interference in a CSG(Closed Subscriber Group) by transmitting messages for controlling resources in one or more first mobile stations. CONSTITUTION: A femto cell base station(170) provides a response which confirms the occurrence of interference mitigation to a macro base station(160). Resources are controlled(250). A member MS(Mobile Station)(182) determines handover to the macro base station. The member MS requests the handover to the macro BS(260). A data route is constructed between the member MS and the macro base station(270).
Abstract:
PURPOSE: A resource management method of a P2P(Peer To Peer) communication in a wireless communication system and apparatus thereof are provided to enable a user to conveniently perform the P2P communication by including a P2P resource control unit. CONSTITUTION: A P2P terminal measures the channel information of a P2P amble signal which is transmitted by the monitoring of the P2P amble signal on P2P links(802). The P2P terminal reports a measured signal strength to a base station through a P2P amble measurement report message(804). The base station allocates the resource of the P2P link to the P2P terminal based on channel information within the P2P amble measurement report message(806).
