IN-BUILDING MOBILE COMMUNICATION SYSTEM AND IN-BUILDING BASE STATION DEVICE

摘要

In an in-building base station device (102) of an in-building mobile communication system, in response to all the transmission requests to a public network received via a plurality of subscriber interfaces corresponding to different communication methods, relay means (111) relays the transmission requests by standing proxy for the transmission requests to the public network via a base station interface transmitting/receiving a cabled or radio signal to/from a base station of the public network operating according to a predetermined communication method. Communication path forming means (112) forms a communication path connecting the subscriber interface corresponding to the mobile communication terminal of the transmission source to the base station interface. Signal conversion means (113) mutually converts a signal transferred via the communication path according to a code method employed in a communication method corresponding to the subscriber interface corresponding to the mobile communication terminal of the transmission source and the base station interface. With this configuration, it is possible to flexibly cope with the change of traffic deviation accompanying the advance of the generation shift associated with the communication method and effectively use the resources such as a signal transmission path.
