The Nokia Telecommunications arm of Nokia Oy yesterday announced a joint venture with Hewlett-Packard Co to develop Intelligent Network systems. The alliance is much less deep than the joint venture company for network management that Hewlett-Packard formed with L M Ericsson Telefon AB at the end of 1992, and does not involve a new company. The agreement calls for integration and further development of key elements of the Intelligent Network architecture, the Service Control Point contributed by Nokia and Hewlett-Packard, the Service Management System from Nokia and the Service Creation Environment from Hewlett. Nokia will convert the last, which currently runs on HP 9000 Unix computers, to run on its own DX200 digital switching system too. All products run under Unix.
