A private network service providing method and system for breaking dependency on a terminal and providing a private network service is provided. The private network service system according to the present exemplary embodiments include: a service linkage server for, when access to a private network is requested by a mobile communication terminal connected to a public network or access of the mobile communication terminal to the private network is requested by a third server, identifying identification information of the mobile communication terminal and requesting an access point name-operator identifier (APN-OI) change to a home subscriber server; the home subscriber server for authenticating whether the mobile communication terminal is subscribed to a private network service when the APN-OI change is requested by the service linkage server, and identifying an access point name (APN) included in a subscriber profile of the mobile communication terminal and changing a public APN-OI recorded in the APN to a private APN-OI when the authenticating is successful; and a mobility management entity for receiving the subscriber profile of the mobile communication terminal from the home subscriber server when there is an attempt of access from the mobile communication terminal, and inducing the mobile communication terminal to connect to a public gateway or a private gateway, using an IP address of the public gateway or IP address of the private gateway corresponding to the APN included in the subscriber profile.

Private network service providing method and system

The disclosure is related to a method for distributing data traffic of a wireless local area network (WLAN) in a WLAN access network while providing service continuity and internet protocol (IP) mobility in a heterogeneous network environment. The method may include receiving data traffic generated by user equipment and from a wireless local area network, selecting one of a first data path and a second data path for the received data traffic based on path decision information associated with the received data traffic, and transmitting the data traffic to Internet through the selected data path. The first data path may transmit the data traffic to Internet through a packet data network (PDN) gateway and the second data path may transmit the data traffic to Internet without passing through the PDN gateway.

Traffic distribution in heterogenous network environment

A first base station may perform a method for controlling handover of a terminal. The method may include setting a handover parameter that is determined based on a handover policy and transmitting a message including the handover parameter to the terminal. The handover parameter includes a service parameter. The service parameter is used when determining a handover condition of the terminal in order to induce handover from the first base station to the second base station according to the handover policy.
