Signal routing from origination nodes (210) to destination nodes (250) in a spread spectrum communication system (100) is provided using spread spectrum routing codes. Origination nodes (210) and destination nodes (250) are identified using specific codes. Signal routes from origination nodes (210) to destination nodes (250) are determined in terms of multi-level paths. Different codes are used to identify the different path levels. Data that is to be sent to a particular user located at a destination node is first spread using the destination code for that destination node. This spread spectrum signal is spread a second time using a first-level path code. In addition, the data can be spread a third time using a second-level path code. During the transmission of the spread data decoding processes are performed and the decoded data is routed based on the results of these decoding processes.

[ What is claimed is:] [1.] In a communication system comprising a plurality of origination nodes and a plurality of destination nodes, a method for routing message information between said plurality of origination nodes and said plurality of destination nodes, said method comprising the steps of:identifying a destination node with a first destination code, said first destination code spreading said message information in an origination node and despreading said message information in said destination node;establishing a first route from said origination node to said destination node, wherein said first route comprises a plurality of intermediary nodes;determining a first set of routing codes for said first route, wherein an intermediary node is identified by a routing code, said routing code spreading said message information in said origination node and despreading said message information in said intermediary node;spreading a first block of said message information into a spread spectrum signal using said first destination code and said first set of routing codes; andsending said spread spectrum signal from said origination node.
