BENACHBARTE ZELLENFUNKTELEFONSYSTEME |
摘要 |
<p>An existing cellular system (X-system 102) is interconnected with another cellular system (M-system 101) via inter-office trunks (150) to add additional switching capacity for providing telephone coverage to mobiles located throughout their common coverage area. X-system (102) includes a control terminal (120) coupled by data and voice lines to base sites (121-124) and by out trunks to a telephone central office (110). M-system (101) includes a control terminal (420) coupled by data and voice lines to base sites (411-415) and by in trunks and out trunks to the telephone central office (110). M-system base sites (411-414) are colocated with corresponding existing X-system base sites (121-124). Paging/access channels are assigned to M-system base sites (411-414) for processing all incoming originations from mobiles and paging mobiles for all outgoing originations. Access-only channels are assigned to X-system base sites (121-124) for processing mobile originations transferred to X-system (102) by a directed retry message from M-system (101). M-system (101) shares the mobile origination traffic with X-system (102) by sending a directed retry message to a percentage of the originating mobiles.</p> |
