Abstract
A method of operating a closed-mode base station, includes broadcasting an interference preamble for providing a notification of an interference situation via a broadcast of system information; checking current service status of the closed-mode base station when the interference situation is reported from a non-subscriber terminal entered a service area of the closed-mode base station; and avoiding the interference situation based on the checked current service status.
Claims17
A method of operating a closed-mode base station, comprising:
- broadcasting system information that indicates an interference preamble for providing a notification of an interference situation;
- receiving the interference preamble from a non-subscriber terminal in a service area of the closed-mode base station;
- checking current service status of the closed-mode base station in response to the interference situation being reported from the non-subscriber terminal;
- and
- avoiding the interference situation based on the checked current service status.
A method of operating a non-subscriber terminal requesting a service within a service area of a closed-type base station, comprising:
- searching a surrounding wireless environment;
- if the closed-mode base station is detected, measuring intensity of signals received from the closed-mode base station;
- comparing the intensity of the signals received from the closed-mode base station with the intensity of signals received from a currently accessed base station;
- and
- if the intensity of the signals received from the closed-mode base station is higher, reporting an interference situation to the closed-mode base station.
A method of operating a non-subscriber terminal, comprising:
- receiving, from a closed-mode base station, system information that indicates an interference preamble for providing a notification of an interference situation;
- and
- transmitting the interference preamble from the non-subscriber terminal to the closed-mode base station if the non-subscriber terminal is in a service area of the closed-mode base station, the non-subscriber terminal being a non-subscriber to the closed-mode base station.
