Abstract: A system for controlling an MBMS(Multimedia Broadcast and Multicast Service) for load distribution and a control method thereof are provided to separate functions, which has to be performed in a BM-SC(Broadcast Multicast Service Center), into one group of functions, which can be processed with a distribution scheme and the other group of functions, which can be processed with a center control scheme by considering properties and mutual relations of the functions, to make system extension easy by properly arranging the separated function at multiple nodes and to enhance reliability by properly distributing the load while the system is being operated. A method for controlling an MBMS(Multimedia Broadcast and Multicast Service) for load distribution comprises the following several steps. A service distribution policy manager requests a load manager of each service control node to estimate a load according to a request for registering a new service(602). The load manager estimates according to the request for estimating the load, and transmits the estimated load to the service distribution policy manager(603). The service distribution policy manager compares the estimated load of each service control node with that of other node, allocates a service control node for the service to be newly registered, and notifies the allocated service control node of the registration of the new service(604,605). A process load distribution policy manager receives a control message like a session initiation request or a session termination request, and compares a measured load value of each service control node with that of other node(606). If the measured load value of each service control node is not over a reference, the process load distribution policy manager allocates one service control node by a round robin scheme. Otherwise, the process load distribution policy manager allocates one service control node which has the smallest measured load value. The process load distribution policy manager transmits the received control message to the allocated service control node, and manages a transaction for processing a response to the control message. If a message received from a mobile communication network is a response to the control message, the process load distribution policy manager transmits the received message to the service control node which is waiting for the corresponding response message by using a transaction identifier.

Abstract: PURPOSE: A method for controlling a new call in a hierarchical cell structure is provided to make a distance between a terminal and a micro base station close for minimizing a forward link signal interference between terminals by operating variably a new assigned area of micro cell according to an amount of traffic. CONSTITUTION: When a terminal tries a new call, an intensity(TPWR) of signal of micro cell is measured(S201) and transmitted to the terminal(S202). On the other hand, a micro base station calculates a value of power parameter(TNEW) and send it to the terminal(S206). Then, the intensity(TPWR) and the value of power parameter(TNEW) are compared with each other(S203). If the intensity(TPWR) exceeds the value of power parameter(TNEW), the terminal performs a new call setup in the micro cell because the terminal is within the area of micro cell(S204). If the intensity(TPWR) is smaller than the value of power parameter(TNEW), the terminal performs the new call setup in a macro cell(S205)

Abstract: PURPOSE: A call connection method considering a hand-off decrement and a traffic distribution of cells in a hierarchy structure is provided to divide usable frequencies into frequency sets for a macro cell and a micro cell, and to endow the macro cell with a highest priority than the micro cell, then to make a mobile terminal connect to the macro cell. CONSTITUTION: A base station has a hierarchy structure which a micro cell(102) and a macro cell(101) are overlapped. Frequency sets for a call connection endowed with various priorities are assigned to mobile terminals. When the call connection is requested, frequencies are evenly distributed to the mobile terminals in order not to generate load. A traffic distribution of cells is controlled. The call connection is firstly requested to the macro cell(101). When a mobile terminal number moving at a high speed or a busy mobile terminal number is less, the mobile terminals use frequencies of the macro cell(101). When a frequency channel for a new call of the macro cell(101) is unusable, when the mobile terminals moves at a low speed, the call connection is attempted to the micro cell(102), and the mobile terminals use the frequencies of the macro cell(101) having a wider service area than that of the micro cell(102).
