Application 08/537,408
no teaching of requesting the first access point to relay a
request and there is no relaying of any request from the first
access point to the second access point (Br8).
With respect to the relevant limitations, the Examiner
repeats the findings of the final rejection (EA6):
The mobile station (node) selects a second base station
([second] access point) based on signal strength and
communicates a request (instruction) to a first base
station ([first] access point) to handoff between base
stations (col. 1, line 45-col. 2, line 43; Figures 1, 2,
8A-8D). The first base station ([first] access point)
relays the request to the second base station ([second]
access point) through a system controller 11 (col. 3,
lines 3-35).
Kojima discloses (col. 6, lines 3-17):
If the cordless station is leaving the cell of base
station 20 and entering the cell of base station 201 2
. . . the controller of cordless station 40 . . . selects
a second, idle timeslot to establish a radio channel with
base station 20 and transmits a channel switching request
2
signal. This request signal is received by base stations
20 and 20 and passed to CLIC's 14 and 14 of PBX 10 and1 2 1 2
thence to main controller 11. When this occurs, the
speech signal from cordless station 40 is also carried on
the second timeslot and it reaches a terminal of the
time-division switch 12 through path 40', while it is
being transported on path 40a through base station 20 .

Figure 8A shows the request going from the cordless station 40
to both base stations 20 and 20 . It is clear that Kojima1 2
transmits a channel switching request signal to both the
current base station 20 (first access point) and the
