The present invention relates to a method of changing a frequency assignment (FA) status in an improved broadband wireless access system where terminals and base stations communicate with each other by using a plurality of FAs. The base station changes the status of one of secondary FA into the status of the pFA in order to adjust a load of the primary FA, and communicates with the terminal through the pFA of which status is changed. When a response is received from the terminal, the base station changes the status of the pFA and communicates with the pFA of the terminal through a new pFA. The status of a previous pFA between the base station and the terminal is changed into the status of the sFA, and a previous sFA is changed into the pFA, so that communication is performed through new FAs.

The present invention relates to a method of broadcasting and receiving a neighboring base station advertisement message in a wideband wireless access system and a handover method using the same. In the present invention, a base station broadcasts a neighboring base station advertisement message including information that indicates that frequency overlay is supported in neighboring base stations to terminals. The terminal confirms whether frequency overlay is supported in the neighboring base stations included in the neighboring base station advertisement message, and can perform handover to a frequency overlay supporting base station as a destination base station. According to the present invention, when a non-frequency overlay communication system and a frequency overlay communication system are mixed with each other, it is possible to ensure that a frequency overlay supporting terminal performs handover from a base station of a frequency overlay communication system to a base station of another frequency overlay communication system.

Disclosed herein are a new indole carboxylic acid bispyridyl carboxamide derivative, a preparation method thereof, and a composition for prevention or treatment of obesity, urinary disorders, and CNS disorders, containing the same as an active ingredient. Because the indole carboxylic acid bispyridyl carboxamide derivatives according to the present invention have high affinity for 5-HTreceptors, act selectively on the 5-HTreceptors, the derivatives rarely have adverse effects caused by other receptors. Because the derivatives effectively inhibit serotonin activity, they may be useful for treatment or prevention of obesity; urinary disorders such as urinary incontinence, premature ejaculation, erectile dysfunction, and prostatic hyperplasia; CNS disorders such as depression, anxiety, concern, panic disorder, epilepsy, obsessive-compulsive disorder, migraine, sleep disorder, withdrawal from drug abuse, Alzheimer's disease, and schizophrenia, associated with 5-HTreceptors.
