Claim:
1. A method in a positioning server for positioning of a communication device, said positioning server being configured to communicate with a plurality of positioning nodes, said method comprising: receiving radio channel characteristics information of said communication device comprising frequency information, sending said received radio channel characteristics information of said communication device to said plurality of positioning nodes, receiving from one or more of said plurality of positioning nodes, signal strength information indicating strength of a signal received by said plurality of positioning nodes from said communication device by using said radio channel characteristics information being sent by said positioning server, receiving positioning information about one or more positions, at which said signal was received, of said one or more of said plurality of positioning nodes along with said signal strength information from said one or more of said plurality of positioning nodes, wherein at least one of the one or more of said plurality of positioning nodes is a mobile positioning node; and determining a position of said communication device based on said received signal strength information and said received positioning information of said one or more of said plurality of positioning nodes, wherein any number of positioning nodes and any proportion of mobile positioning nodes to static positioning nodes may be used to determine the position of said communication device.
