<p>The invention relates to cellular packet switched telecommunication network. The basic network consists of subscriber specific network stations (NS1-NS9), which are mainly connected by radio. The address of a network station consists of its geographic coordinates and altitude coordinate. When the network station is taken into use, it determines its location by using e.g. GPS technique and registers itself to surrounding networks. The network station contains a small base station to enable the use of wireless terminals (MS11, MS12, MSnx). The network connection between the calling and called terminal, is realized via the network stations on the basis of the routing information in the network stations. The network operates in packet switched mode and beneficially in connection-oriented mode. Using upper layer network stations and long distance connections between them can interconnect separate basic networks. The wireless terminals can be equipped with routing feature to expand the coverage area of the basic network and to add capacity.</p> |
