Big thanks for Deidara , he solved this problem :

Code:
#include < amxmodx >
public plugin_init()
{
register_plugin("PausePlugin","1.0","Deidara");
register_logevent("round_end", 2, "1=Round_End");
register_logevent("round_start", 2, "1=Round_Start")
}
public round_end()
{
pause("ac","csdm_spawn_preset.amxx");
}
public round_start(id)
{

}
public start()
{
unpause("ac","csdm_spawn_preset.amxx");
}
