A method and an apparatus are provided in a wireless communication system. The method includes generating mobility history information upon entering an evolved universal mobile telecommunications system (UMTS) radio access network (E-UTRAN) from another radio access technology (RAT), the mobility history information including information on a time duration for which the terminal stayed outside of the E-UTRAN; receiving, from a base station, a request for the mobility history information; and transmitting the mobility history information to the base station, in response to the request.

Method and apparatus for managing user equipment history information in wireless communication network

The present invention relates to a wireless communication system and method for establishing connection between a User Equipment (UE) and a Mobility Management Entity (MME) in the wireless communication system in which the data-centric terminal requests the mobility management entity for attachment and checks, when the mobility management entity responds, data-centric features supported by the mobility management entity. According to the present invention, it is possible to connect the data-centric terminal to the mobility management entity supporting the data-centric features of the corresponding data-centric terminal efficiently in the wireless communication system.

Wireless communication system and method for establishing a connection between user equipment and a mobility management entity thereof

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.

Method and apparatus for supporting local IP access in a femto cell of a wireless communication system

A method and an apparatus are provided in a wireless communication system. Mobility history information is generated including information on a time duration corresponding to out-of-service. It is identified whether the terminal is in a radio resource control (RRC) connected mode. The mobility history information is transmitted to a base station if the terminal is in the RRC connected mode.

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 relates to a wireless communication system and a connection method between user equipment and a mobility management entity and comprises: selecting a mobility management entity and requesting identification information for user equipment by a base station when the user equipment is connected; determining whether to assign identification information by the mobility management entity; and if the identification information is not assigned, selecting another mobility management entity by the mobility management entity, assigning identification information to the user equipment by the other mobility management entity, and performing a connection with the other mobility management entity by the user equipment. According to the present invention, user equipment can be efficiently connected with a mobility management entity in a wireless communication system.

Wireless communication system and connection method between user equipment and a mobility management entity

An access admission control method and system for and SAE/LTE system is provided for determining whether to accept or reject an access of a User Equipment (UE) to a Home evolved Node B (HeNB) based on the subscriber information of the UE. In an access admission control method according to the present invention, a HeNB or HeNB Gateway (HGW) transmits, when an access request message is received from a UE, the access request message to a Mobility Management Entity (MME) together with a CSG ID of the HeNB, and the MME determines, whether to accept or reject the access of the UE to the HeNB based on whether the CSG ID is contained in a white list associated with the UE.

Access admission control method and system for mobile communication system

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 congestion control method for a Mobility Management Entity (MME) in a mobile communication system. The method includes: receiving a mobility management request signal from a user equipment (UE) having Packet Data Network (PDN) connections for at least one Access Point Name (APN); checking whether the APN is in a congested state; and rejecting, when a specific APN is in a congested state, the mobility management request.

Method for controlling congestion in mobile communication system

A method and an apparatus for controlling network access of a User Equipment (UE) based on the network's load and time tolerance (delay tolerance) are provided. A network access method for a terminal in a wireless communication system includes sending an access request message containing a time-tolerant indicator at a predefined time, determining, when a reject message is received, a cause value and a hold time contained in the reject message, and re-sending the access request message after the hold time elapses.

Method and apparatus for controlling network access of UE in wireless 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.

Wireless communication system and method for transmitting content in wireless communication system

According to an embodiment of the present invention, the invention discovers an address of a LGW, which can be sued in HeNB, determines whether session continuity is supported or not when a terminal using the LGW is moved to another HeNB in a network wherein a structure supporting Session Continuity and a structure not supporting Session Continuity are mixed, and processes active mode mobility and idle mode mobility based on the same.
