Abstract:
A communication system, comprising:a wireless unit having a first transmitter and a first receiver; a first intelligent base station comprising a second transmitter, a second receiver, an over-the-air processor, a line processor, and an internal signaling protocol layer, wherein said over-the-air processor manages communication between said intelligent base station and said wireless unit over a wireless communication channel, wherein said line processor comprises a base station subsystem management application part (BSSMAP), a signaling connection control part (SCCP), and a message transfer part (MTP), and wherein said internal signaling protocol layer allows communication of signaling information between said over-the-air processor and said line processor; a non-wireless unit connected to said wireless unit, said non-wireless unit exchanging information with said intelligent base station using said wireless unit; a mobile switching center coupled to said intelligent base station over an interface; a second intelligent base station, said second intelligent base station connected to said mobile switching center over a second interface; and at least one mobile user station which communicates with the first intelligent base station or the second intelligent base station over a second wireless communication channel, wherein: the first intelligent base station and the second intelligent base station are connected across a physical link, said interface connecting the first intelligent base station and the mobile switching center comprises a first signaling channel and a first bearer channel for supporting a call from said at least one mobile station, and the first intelligent base station establishes, over said physical link connecting the first intelligent base station and the second intelligent base station, a second signaling channel and a second bearer channel between the first intelligent base station and the second intelligent base station to support a third wireless communication channel established between said at least one mobile user station and the second intelligent base station upon handover of said call from the first intelligent base station to the second intelligent base station.
