Abstract: Disclosed is an advertising service method using D2D communication for efficiently using limited radio resources and control channel resources. The advertising service method includes setting a D2D common bearer with a network, receiving advertising terminal information from at least one other advertising terminal through the D2D common bearer, registering the advertising terminal in the network, transmitting advertising information to the at least one other advertising terminal and a user terminal through the D2D common bearer, and setting a user terminal and a D2D dedicated bearer on the basis of information received from the network. Accordingly, an advertisement can be easily transmitted to a plurality of user terminals which were not previously connected, and a collision between advertising terminals which are located in plurality in a specific area and transmit advertisements can be avoided.

Abstract: A method and apparatus for perceiving access between a terminal and a small base station is provided. A macro base station transmits a small cell addition/change request message to a small base station that a terminal enters and transmits a message for access to the terminal when receiving a response message from the small base station. Then the macro base station obtains results of access between the terminal and the small base station and determines whether the access between the terminal and the small base station is completed based on the result of access.
