US 7684369 B2Abstract
Antenna 71-1 Antenna duplexer 72-1 that is connected to the feeding point of the antenna 71-1. Receiving part 73-1 that is connected to the reception output of the antenna duplexer 72-1. Router 74-1 that is connected to the one end of an inter-office link provided between the radio base station 70-1 and an exchange (not shown), and to whose incoming route the output of the receiving part 73-1 is connected. Transmitting part 75-1 that is connected in series to the outgoing route of the router 74-1 and whose output is connected to the transmission input of the antenna duplexer 72-1. Controlling part 76-1 having input/output ports that are connected to the control terminals of the receiving part 73-1, the router 74-1, and the transmitting part 75-1, respectively, and a communication port that is connected to the one end of the above-mentioned communication link 83-1. The radio base station 70-2 has the same configuration as the radio base station 70-1. Therefore, the components of the radio base station 70-2 will be given the same reference symbols as those of the radio base station 70-1 except that the former will have a suffix “2” instead of a suffix “1,” and will not be described or shown in the drawings.
Secures an IP address (for the sake of simplicity, it is assumed here to be “192.168.1.2”) as a second IP address by itself or in cooperation with the radio base station 70-2. The IP address is in such a value range that the radio base station 70-2 is allottable and is not assigned to any terminal or call (indicated by symbol (i) in FIG. 7). In the following description, for the sake of simplicity, it is assumed that the host address portions of the first IP address and the second IP address are defined under different subnet masks corresponding to the respective radio base stations 70-1 and 70-2 (wireless zones 81-1 and 81-2) so as to secure compatibility with the known mobile-IP that does not conform to the mobile communication and the radio transmission sufficiently. Allows a relationship between the terminal 82 (or the transition destination channel assigned to the terminal 82) and the second IP address to be reflected in routing information held in the router 74-2 (indicated by symbol (i) in FIG. 7). Sends a message “binding update confirmation” containing the second IP address to the terminal 82 via the communication link 83-2 and the radio base station 70-2 (indicated by symbol (k) in FIG. 7). The terminal 82 completes the handover by using, as one of the following, the second IP address contained in the binding update confirmation as an IP address that has been assigned in place of the first IP address (indicated by symbol (m) in FIG. 7):
JP-A-2001-45534 (claims 4,6, 8, and 9, paragraphs 0013, 0015, 0018, 0023, 0034, 0035, 0040-0042, 0044-0046, 0050, 0056-0058, 0060, 0063-0065, and 0067) JP-A-2001-189954 (abstract, paragraph 0031) JP-A-10-117167 (abstract, claim 1) JP-A-11-122672 (claims 1-16) JP-A-10-190633 (claim 1, paragraph 0001) JP-T-10-509287 (abstract; the term “JP-T” as used herein means a published Japanese translation of a PCT patent application) JP-A-2000-286898 (abstract, claim 1, paragraphs 0003 and 0016) Incidentally, in the above prior art examples, a handover is attained by executing the second processing (indicated by symbols (g)-(m) in FIG. 7) for assignment of a second IP address that is to replace a first IP address after completion of the first processing (indicated by symbols (a)-(f) in FIG. 7) for realizing update of a physical radio channel.
