    Abstract: PROBLEM TO BE SOLVED: To provide a method for automatically monitoring the trunk a communication system without needing any operator and without interrupting service to the user of the trunk by installing a means for deciding the next trunk to be tested in accordance with a trunk selection algorithm. SOLUTION: The trunk to be tested is selected by a processor 124 or an exchange 118. The processor 124 uses a selection algorithm for selecting the trunk to be tested. The exchange 118 selects the trunk which is directly connected to all the trunks of all user communication links and is decided from a list or from a prescribed trunk order. The trunk of a communication system can periodically or non-periodically and automatically be monitored without using an operator and without interrupting service to the user of the trunk.

    Abstract: PROBLEM TO BE SOLVED: To improve the capability of hybrid inner/outer sectoring cell, without increasing cost and antennas by allocating existing sector antennas to a base station-side used for the sectors of outer communication cover areas for generating a nondirectional inner communication cover area. SOLUTION: A hybrid inner/outer sectoring cell 100 is constituted of inner/ outer communication cover areas 112/114 which are obtained by dividing it into an omnisector structure 112 and sectors 116, 118 and 120. Moving auxiliary hand-off is used without digital movement for hand-off between the sectors of the sectoring cell 100 and between the sectoring cells 100. The base station of the sectoring cell 100 communicates the signal of the cover area 112 with three existing nondirectional sector antennas at the same time which the base station uses for the cover areas 114. Thus, the increase in cost and space are eliminated by the use of the existing antennas.

    Abstract: Sharing the existing sector antennas at the base station each of which corre sponds to one sector of the outer communication coverage area to create an omnidirectional inner communication coverage area. When transmitting or receiving data from a mobi le in one sector of the outer communication coverage area only one antenna is used, and when transmitting or receiving data from a mobile in the inner communication coverage area all th e antennas are used. This allows an increase in capacity of the hybrid inner/outer sectored cell without the additional cost of adding further antennas.

    Abstract: Sharing the existing sector antennas at the base station each of which corresponds to one sector of the outer communication coverage area to create an omnidirectional inner communication coverage area. When transmitting or receiving data from a mobile in one sector of the outer communication coverage area only one antenna is used, and when transmitting or receiving data from a mobile in the inner communication coverage area all the antennas are used. This allows an increase in capacity of the hybrid inner/outer sectored cell without the additional cost of adding further antennas.
