Abstract
A method for determining a root sequence index by a network management server, according to an embodiment of the disclosure, comprises the steps of: determining whether to reassign a root sequence index of a cell managed by a base station; when reassigning the root sequence index of the cell, determining the root sequence index to be reassigned to the cell on the basis of the number of handovers between the cell and adjacent cells of the cell; and transmitting the determined root sequence index to the base station.
Claims15
A method for a network management server to determine a root sequence index, the method comprising:
- determining whether to reassign a root sequence index of a cell managed by a base station based on a random access channel (RACH)-related statistical information including a ratio between a number of random access (RA) preamble signals transmitted by at least one terminal to the base station and a number of scheduled transmission messages transmitted by the at least one terminal to the base station;
- determining a root sequence index to be reassigned to the cell based on a number of handovers between the cell and neighbor cells thereof, in case that the root sequence index is determined to be reassigned;
- and
- transmitting the determined root sequence index to the base station.
A network management server capable of determining a root sequence index, comprising:
- a controller configured to:
- determine whether to reassign a root sequence index of a cell managed by a base station based on a random access channel (RACH)-related statistical information including a ratio between a number of random access (RA) preamble signals transmitted by at least one terminal to the base station and a number of scheduled transmission messages transmitted by the at least one terminal to the base station, and
- determine a root sequence index to be reassigned to the cell based on a number of handovers between the cell and neighbor cells thereof, in case that the root sequence index is determined to be reassigned;
- and
- a communication circuit configured to transmit the determined root sequence index to the base station.
