BASE STATION, CORE SERVER AND UPLINK TRANSMISSION METHOD FOR USE IN A WIRELESS NETWORK COMMUNICATION SYSTEM

PURPOSE: A base station, a core server and an uplink transmission method for using in a wireless network communication system are provided to assign machine to machine (M2M) wireless apparatuses belonging to the same group for transmitting uplink transmission requests within a specific time interval. CONSTITUTION: A wireless network communication system comprises a first (M2M) wireless apparatus group (17), a core server (13) and a base station (11). The core server is configured to create a time assignment instruction (22) according to a first uplink transmission status of the first M2M wireless apparatus group. The base station comprises a transceiver and a timing controller. The transceiver is configured to receive the time assignment instruction from the core server. The timing controller is configured to control the transceiver to transmit a first time assignment signal (24) to the first M2M wireless apparatus group according to the time assignment instruction. At least one M2M wireless apparatus of the first M2M wireless apparatus group transmits at least one first uplink transmission request (R1) to the base station within a first time interval according to the first time assignment signal.
