Abstract: PURPOSE: A TNL(Transport Network Layer) connection method of A base station and apparatus thereof which uses a downlink receiver are provided to reduce the complexity of dynamic TNL connection by using additional downlink receiver. CONSTITUTION: A peripheral cell downlink reception control unit(312) monitors the PCI(Physical Cell Identity) value of a monitoring cell. An SON(Self Organizing Network) agent(320) obtains the IP address of a subbase station corresponding to the changed PCI value. A base station controller(330) decides whether to setup the connection of a new TNL based on the obtained IP address.

Abstract: 본 발명은 무선 통신 시스템의 정적 사용자 검출 시스템, 방법 및 그를 이용한 호 수락 제어 방법에 관한 것이다.
무선 인터넷 시스템에 위치하는 다수의 기지국은, 특정 시간 간격으로 정적 사용자를 검출하고 이를 일정 경우의 수 만큼 단말별로 유지한다. 이렇게 유지되는 정적 사용자에 대한 정보는 기지국 단위의 정적 확률로 재 계산되어 호 수락 제어에 이용할 수 있다.
따라서 무선 인터넷 시스템에서 검출된 정적 사용자의 단말을 정적 확률이라는 확률 값으로 계산하고, 이를 호 수락 제어에 이용함으로써 불필요한 자원의 예약을 최소화할 수 있다.

Abstract: A method for managing an active set in an OFDMA(Orthogonal Frequency Division Multiple Access)-TDMA(Time Division Multiple Access) based mobile Internet system is provided to prevent a waste of resources and thus enhance performance of the overall system by constructing an active set with base stations of high mobility, managing base stations of low mobility as a semi-active set, and omitting information about the reservation of resources among pre-handover contents. An active set and a semi-active set are discriminately operated by using statistical data about movement habit of a terminal in addition to signal conditions. The terminal is operated based on the past experience values with respect to probability of movement from the current location to neighbor base stations, and if the probability of movement of the terminal to a base station among target base stations within the active set is smaller than any threshold value operated by a system, the terminal is admitted to a semi-active set.

Abstract: Disclosed is a protocol embodying system and method in the GGSN. An IP layer is provided between the GPRS network and the PDN and performs routing between the two networks, and performs routing between the protocols of the first and second network layers and the transfer layer protocol on the GPRS network. A virtual driver is provided on the lower part of the IP layer, is connected to the protocol of the GPRS tunneling provided to the upper part of the IP layer on the GPRS network, and is operable as the lower interface of the IP layer. Since the upper part and the lower part of the IP are appropriately connected by the virtual driver, a single IP is needed in the system, and the embodied configuration becomes simpler.

Abstract: PURPOSE: A method for synchronizing a control message with a user packet in a wireless communication network is provided to reduce losses of transmitted user packets and improve the reliability of the wireless communication network by using a null IP packet. CONSTITUTION: A receiving process is performed to receive an user packet(601). A setup state of a flag of WFN is checked inside of a session table by a gateway GPRS support node(602). A routine process of the received packet is performed to an external network if the flag of WFN is not set up inside of the session table(603). A setup state of an address field of the header is checked if the flag of WFN is set up inside of the session table(604). Buffered packets are transmitted to a terminal if the address field of the header is set up as 0 inside of the session table and a null IP packet is received(606). The setup state of WFN is released(607). An error state is indicated if the address field of the header is not set up as 0 inside of the session table(605).

In addition, the IP layer is used for performing a routing operation between protocols of a first and a second network layer and a protocol of a transmission layer in the GPRS network. The virtual driver is located below the IP layer in order to be connected to a protocol of GPRS tunneling. The virtual driver is operated as a sub-interface of the IP layer.
