Abstract:
1. A communication node which is a base station node, comprising: a first interface unit connected to a first network which is a radio network; a second interface unit connected to a second network which is a non-radio network; a processing unit configured to voluntarily recognize one communication node on the first network as one of constituent elements that constitute said communication node, and to disclose an own configuration information regarding what its constituent elements are to another communication node on the second network through the second interface unit such that said one communication node is recognized as a part of the communication node on the second network by said another communication node on the second network while said one communication node is actually existing only on the first network; wherein the processing unit also detects a first message identifier on the second network which is described in a packet received through the second interface unit, attaches a second message identifier on the first network to the packet at a time of transferring the packet to the first network, stores a correspondence between the first message identifier and the second message identifier into a correspondence table, and identifies a message identifier on the second network corresponding to one message identifier on the first network which is described in a packet sent from the first network, by referring to the correspondence stored by the correspondence table according to said one message identifier.
