A method for load balancing in a base station is provided. The base station updates a traffic amount of a current time by reflecting a predicted traffic amount of a future time in the traffic amount of the current time, and determines parameters necessary for load balancing of the base station by comparing the updated traffic amount of the current time with a predetermined threshold.

Base station load balancing method and apparatus

A method for transmitting downlink by a network node. The network node creates downlink data for a terminal which is in a radio resource control (RRC) idle state. The network node inserts the downlink data into a first paging message for transitioning the terminal to an RRC connected state, when a size of the downlink data is smaller than a reference value. In addition, the network node transmits the first paging message to the terminal through a base station.

Method and apparatus for transmitting downlink data and uplink data in NB-IoT system

A method and an apparatus for controlling an MBMS service provided at a specific location in an LTE system. In an MBMS service system of the present invention, it is possible to efficiently control and manage a valid MBMS service only at a specific location. For example, it is possible to more efficiently manage the effective MBMS content only in the specific cell or the specific cluster (set of the specific cells).

Method and apparatus for controlling location based MBMS service

A method of providing a multicast service is provided by a terminal in a terminal-to-terminal direct communication. The terminal transmits a service start request message requesting a start of a multicast service to a multicast server, and receives a service start response message including a result of permitting a start request from the multicast server. The terminal receives, via a base station, resource information of a resource which a multicast coordinator allocates to the multicast service in accordance with a request of the multicast server, and transmits multicast service data based on the resource information.

A method for controlling, by a base station, uplink transmission power of a mobile terminal. The base station receives an available transmission power amount of the mobile terminal from the mobile terminal. The base station determines a target channel quality value corresponding to a current location of the mobile terminal, on the basis of the available transmission power amount. The base station determines a received channel quality value using an uplink data channel received from the mobile terminal. Further, the base station determines a transmit power control (TPC) using a difference between the target channel quality value and the received channel quality value.
