Abstract
Proposed are a mission-critical user priority-based random access method and apparatus for a collision resolution in a coexisting PS-LTE and LTE-M network. The MCHP-RA method includes broadcasting information as part of a system information block (SIB) 2 in order for an eNB to allocate a random access channel (RACH) slot in a network environment in which an LTE-based public safety (PS-LTE) network and an LTE-based marine (LTE-M) network coexist, selecting an emergency slot as a next RACH slot when the number of mission-critical high priority-based user equipments (MCHP UEs) is greater than a predefined threshold and processing the MCHP UEs during a random access procedure, and selecting a normal slot as a next RACH slot when the number of MCHP UEs is smaller than a predefined threshold and processing the MCHP UEs, wherein the eNB may allocate the RACH slot based on configurations in order to prevent a preamble collision.
