Abstract:
The present invention relates to a method of transmitting data by a transmission terminal included in a direction communication network between terminals, in which the method includes: determining a data frame transmitting data; requesting reservation of a data transmission interval included in a data frame at a transmission request interval included in the data frame; receiving a response signal transmitted at a transmission response interval included in the data frame; and transmitting the data through the data transmission interval by analyzing a response signal. The present invention relates to a method of receiving data by a reception terminal included in a direction communication network between terminals includes: receiving a request signal requesting reservation of a data transmission interval included in a data frame at a transmission request interval included in the data frame; broadcasting a response signal at a transmission response interval included in the data frame; receiving a signal field of a plurality of data slots included at the data transmission interval to identify a first data slot used by a terminal having a corresponding link identification among the data slots; and receiving the data from the first data slot. [Reference numerals] (300,310) 1 data resource; (303,315) Data transmission interval

Abstract:
PURPOSE: A uplink data transmission method in a mobile communication system, base station, and terminal are provided to transmit uplink data without connecting to a network an M2M(Machine to Machine) terminal of an idle mode. CONSTITUTION: When uplink transmission target data is generated in an idle mode, a terminal transmit a ranging request message including a group identifier, or a non-connection transmission indicator, or uplink data(S202,S210). The group identifier is allocated according to each terminal group. The non-connection transmission indicator indicates the transmission of the uplink data in a network non-connection state. The terminal receives a raging response message from the base station(S222).

PURPOSE: A random access control method, a base station supporting the same, and a terminal are provided to reduce load of a base station based on ranging configuration information allocated to an M2M terminal. CONSTITUTION: A terminal receives a broadcasting message including random access related parameters from a base station(S100). The terminal receives information for indicating the random access related parameters from the base station in an idle mode(S120). The terminal attempts to access the base station by using information for indicating the random access related parameters(S130).
