`ABSTRACT
`
`A method and apparatus is provided for the time-based pro(cid:173)
`visioning of wireless devices. A network access point moni(cid:173)
`tors operation of wireless devices within a service region.
`When provisioning logic is activated at the network access
`point, the access point determines if the tracked parameter
`(such as power on or the onset of signal transmission) of the
`wireless device occurs within a designated time interval from
`the time of the provisioning activation. If the tracked device
`qualifies, the network access point proceeds with provision(cid:173)
`ing the device. In one system embodiment, the network
`access point tracks the power on time of wireless devices.
`When a wireless device to be authorized is powered on, the
`provisioning logic at the network access point notes the
`power on time. The user then activates the provisioning
`access at the network access point, and the network access
`point provisions the wireless device if it is recently powered
`on.

`
`FIELD OF THE INVENTION
`
`The invention relates to the field of wireless connections
`between a wireless device and a network. More particularly,
`the invention relates to access provisioning between one or
`more wireless devices and an intranet access point.
`
`BACKGROUND OF THE INVENTION
`
`In local area networks, such as wireless home networks,
`one or more wireless devices, e.g. such as IEEE 802.11 b
`devices, are linked to the network by a provisioning process
`through a network access point. When a user acquires a new
`wireless device, they need to securely tie it to their intranet,
`which comprises telling the intranet to accept wireless com(cid:173)
`munications from the device, as well as provisioning the
`device with key material, such as for creating an encrypted
`connection. In conventional networks having one or more
`devices to be provisioned to a network access point, device
`identification information, such as a MAC address, is
`required to be communicated from the wireless device to the
`access point.
`Several methods have been described for wireless access
`provisioning to integrate wireless devices into a network.
`M. Cudak, B. Mueller, J. Kelton, and B. Classon, Network
`Protocol Method, Access Point Device and Peripheral
`Devices for Providing for an Efficient Centrally Coordinated
`Peer-to-Peer Wireless Communications Network, U.S. Pat.
`No. 6,058,106, discloses a "peer-to-peer wireless communi(cid:173)
`cations network wherein the access point device: (1) broad(cid:173)
`casts a block assignnient that specifies a wireless source
`peripheral device and a wireless destination peripheral
`device; (2) receives, from the wireless destination peripheral
`device, sequence information; (3) determines whether the
`sequence information represents one of: a negative acknowl(cid:173)
`edgment and a positive acknowledgment with a sequence
`number; (4) forwards an acknowledgment to the wireless
`source peripheral based on the sequence information, and
`repeats steps (1)-( 4)until Nblocks of data, Na predetermined
`integer, have been transferred from the wireless source
`peripheral to the wireless destination peripheral."
`J. Lin, P. Alfano, and S. Upp, Method and Apparatus for
`Performing Bearer Independent Wireless Application Service
`Provisioning, U.S. Pat. No 6,275,693 disclose a provisioning
`system, in which a "mobile communication device contacts a
`provisioning proxy over the wireless bearer network, which
`in turns contacts a provisioning center over a public network.
`A provisioning tunnel is then established between the provi(cid:173)
`sioning center and the mobile communication device. Once
`the provisioning tunnel is set up, the user of the mobile
`communication device can subscribe to, or unsubscribe from
`wireless application services."

`within a designated time interval from the time of the provi(cid:173)
`sioning activation. If the tracked device qualifies, the network
`access point proceeds with provisioning the device. When a
`wireless device to be authorized is powered on, the provision-
`s ing logic at the network access point notes the power on time.
`The user then activates the provisioning access at the network
`access point, and the network access point provisions the

`The disclosed prior art systems and methodologies thus
`provide basic provisioning for wireless devices to a network
`through an access point. However, for many networks, such 15
`provisioning schemes are often impractical, either for wire(cid:173)
`less devices which lack a user interface which is configured
`for communicating provisioning information, or for simple
`home-based intranets. For example, device identification
`information, such as a MAC address, is often required to be 20
`manually transcribed from the wireless device to the access
`point, since wireless devices often lack a user interface con(cid:173)
`trol to reveal such identifying information. For example, a
`wireless picture frame device typically lacks a control inter(cid:173)
`face read or extract identification information, such as a MAC 25
`address.
`While some wireless devices include a user interface for
`dedicated device functionality, e.g. such as a user control for
`a game box or a digital video recorder, a dedicated user
`interface is often incapable or cumbersome to be used to 30
`communicate device identification and to exchange provi(cid:173)
`sioning information. In addition, while some wireless devices
`provide a user interface control which can reveal such iden(cid:173)
`tifying information, provisioning procedures still require a
`user to be technically proficient to properly initiate and com- 35
`plete a provisioning process.
`It would therefore be advantageous to provide a network
`provisioning system, which does not require a user interface
`for the initiation of a provisioning process. The development
`of such a wireless access provisioning system would consti- 40
`tute a major technological advance.
`Furthermore, it would be advantageous to provide a wire(cid:173)
`less access provisioning structure and process with minimal
`device requirements and/or user proficiency, whereby a wire(cid:173)
`less device is readily provisioned by the provisioning system, 45
`and whereby other devices within an access region are pre(cid:173)
`vented from being provisioned by the provisioning system.
`The development of such a provisioning system would con(cid:173)
`stitute a further technological advance.
`As well, it would be advantageous that such a wireless so
`access provisioning system be integrated with easily moni(cid:173)
`tored parameters of a wireless device, such as the time moni(cid:173)
`toring of power on and/or start of signal transmission. The
`development of such a provisioning system would constitute
`a further major technological advance. The development of 55
`such a time-based wireless access provisioning system for
`provisioning secure encrypted communication would consti(cid:173)
`tute a further technological advance.

`FIG.1 is a schematic plan view 10 ofa time based wireless
`access provisioning system 20. FIG. 2 is a functional block
`diagram of a time based wireless access provisioning system
`20, comprising a network access point 12 adapted to provide
`time-based provisioning with a wireless device 14.
`The network access point 12 shown in FIG. 2 comprises a
`transceiver 32 and antenna 34, which provides communica(cid:173)
`tion 16 to one or more wireless devices 14. The communica-

`link, signal 28 from a wireless device 14 to the access point,
`as well as an output, i.e. forward link, signal 30, from the
`access point 12 to the wireless device 14.
`As seen in FIG. 2, the network access point 12 typically
`comprises network logic & componentry 36, such as net(cid:173)
`working functions 40, thereby providing communications
`between one or more authorized wireless devices 14 and a

`in FIG. 1 also comprises a network connection 38 to one or
`more networks 39, such as to wired devices within a LAN,
`and/or to other networks, such as the Internet. The network
`access point 12 shown in FIG. 2 comprises an access control
`list 42, which identifies wireless devices 14 which have
`proper access to the local network 17 (FIG. 1), such as by
`storing accepted device identifications 50 as list elements

`ments to other wireless devices 14. The wireless device 14
`60 comprises communication logic and componentry 48, and
`comprises an associated device identifier 50, e.g. such as a
`unique MAC address, which is communicatable to the net(cid:173)
`work access point 12, whereby the wireless device 14 can be
`controllably provisioned into the network 17 by the network
`65 access point 12. The wireless device 14 also comprises power
`26, e.g. wired or battery, and power activation 26. In some

`SUMMARY OF THE INVENTION
`
`A method and apparatus is provided for the time-based
`provisioning of wireless devices. A network access point
`monitors operation of wireless devices within a service
`region. When provisioning logic is activated at the network
`access point, the access point determines if the tracked
`parameter, such as the power on, of the wireless device occurs

`system 20, the wireless device is an IEEE 802.11 WLAN
`and/or Bluetooth™ compliant device.
`The network access point 12 shown in FIG. 1 is located
`within a service area 18 for a network 17, such as a wireless
`local area network (WLAN) or a wireless personal area net-
`work (WPAN), and typically communicates 16 with a one or
`more wireless devices 14 which operate within the service
`area 18, as well as to other wired devices connected to the
`network, and to connected networks, such as the Internet.
`As seen in FIG. 1, the time based wireless access provi- 10
`sioning system 20 can be used for a wide variety of wireless
`devices 14a-14n which are adapted to communicate with the
`network access point 12, such as but not limited to a desktop
`computer 14a, a portable laptop computer 14b, a network
`printer 14c, a digital video recorder 14d, a game box 14e, a 15
`portable phone 14{, a personal digital assistant (PDA) 14g,
`and/or a wireless picture frame 14h.
`The network access point 12 provides time-based provi(cid:173)
`sioning to ensure that only authorized wireless devices 14 can
`operate within the local network 17, such as within a home 20
`HM, and to prevent unauthorized wireless devices 14, such as
`device 14n in FIG. 1, from gaining access to the network 17.
`In the time based wireless access provisioning system 20,
`the network access point 12 also comprises time based pro(cid:173)
`visioning 44, which is activatible 46, such as manually by a 25
`user U. The time based wireless access provisioning system
`20 securely integrates one or more wireless devices 14 into
`the local area network 17. A properly timed interaction 57
`(FIG. 3, FIG. 4) between a wireless device 14 to be provi(cid:173)
`sioned and the network access point 12 acts to qualify the 30
`wireless device 14 to the network access point.
`Time-Based Provisioning Process. FIG. 3 is a flow chart of
`a time based wireless access provisioning process 52a. The
`network access point 12 tracks 54 the power on time of
`wireless devices 14, whereby the powered wireless device 35
`begins transmission of a reverse link signal 28. When a wire(cid:173)
`less device 14 to be authorized is powered on 56, the provi(cid:173)
`sioning logic 44 at the network access point 12 notes the
`power on time 82 (FIG. 5). The user U then activates 58 the
`provisioning access 44 at the network access point 12, typi- 40
`cally by pressing an activation button or switch 46.
`In response to a properly timed interaction 57, the network
`access point 12 provisions the wireless device 14 automati(cid:173)
`cally. As seen in FIG. 3, the network access point 12 deter(cid:173)
`mines 60 if there is a recent power on of a wireless device 14, 45
`e.g. such as within 5 minutes. If the wireless device 14 was
`recently powered 56, such as within an acceptance time inter(cid:173)
`val 74 (FIG. 5), the positive determination logic 62 allows the
`network access point 12 to initiate provisioning 64.
`As seen in FIG. 3, the time based wireless access provi- 50
`sioning process 52a also prevents network access from
`devices 14whicharepoweredon 78 (FIG. 5) at an earlier time
`88 (FIG. 5). If a wireless device 14 is powered on at a time 88
`before the acceptance time interval 74 (FIG. 5), the negative
`determination logic 66 allows the network access point 12 to 55
`deny access 68 to the device, preventing provisioning 64 into
`the network 17.
`FIG. 5 shows a simplified timeline 70a for a time based
`wireless access provisioning process 52a. The enhanced net(cid:173)
`work access point 12 tracks power on 56 of wireless devices 60
`as a function of time 72. As seen in FIG. 5, the network access
`point 14 notes the start time 82 of the power on 56 of a
`wireless device 14 which is desired to be provisioned within
`the network 17. The user then activates provisioning logic 44
`at the network access point 12, at time 86. The provisioning
`logic 44 typically comprises an acceptance time interval 74,
`e.g. such as a 5 minute interval 7 4, having a start time 84 and
`
`6
`an end time 86, within which desired devices 14 are accepted
`62 (FIG. 3). As seen in FIG. 5, the time interval 76 for the
`desired device 14 properly falls within the acceptance interval
`7 4, such that the provisioning logic 44 accepts 62 the wireless
`device 14, and initiates provisioning 64.
`As further seen in FIG. 5, the network access point 14 also
`notes the start time 88 of the power on 78 of a second wireless
`device 14, which is not necessarily desired to be provisioned
`by the network access point 12. When the user activates the
`provisioning logic 44 at the network access point 12, at time
`86, the time interval 80 for the second device 14 falls outside
`the acceptance interval 74, i.e. failing 66, time-based deter(cid:173)
`mination 60 (FIG. 3) such that the provisioning logic 44
`denies 68 the second wireless device 14, and prevents provi(cid:173)
`sioning 64.
`Alternate Time-Based Provisioning Process. FIG. 4 is a
`flow chart of an alternate time based wireless access provi(cid:173)
`sioning process 52b, in which a desired wireless device 14 to
`be provisioned is powered on after the provisioning logic 44
`is activated. As above, the network access point 12 tracks 54
`the power on time of wireless devices 14, whereby the pow-
`ered wireless device begins transmission of a reverse link
`signal 28. The user U then activates 58 the provisioning
`access 44 at the network access point 12, typically by pressing
`an activation button or switch 46. When a wireless device 14
`to be authorized is powered on 56, the provisioning logic 44
`at the network access point 12 notes the power on time 82
`(FIG. 6).
`In response to a properly timed interaction 57, the network
`access point 12 provisions the wireless device 14 automati(cid:173)
`cally. As seen in FIG. 4, the network access point 12 deter(cid:173)
`mines 60 if there is a recent power on of a wireless device 14,
`after the provisioning logic 44 is activated 58. If the wireless
`device 14 was recently powered 56, such as within an accep-
`tance time interval 74 (FIG. 6), the positive determination
`logic 62 allows the network access point 12 to initiate provi-
`sioning 64.
`As seen in FIG. 4, the alternate time based wireless access
`provisioning process 52b also prevents network access from
`devices 14 which are powered on 78 (FIG. 6) at an earlier time
`88 (FIG. 6). If a wireless device 14 is powered on at a time 88
`before ( or after) the acceptance time interval 74 (FIG. 6), the
`negative determination logic 66 allows the network access
`point 12 to deny access 68 to the device 14, preventing pro(cid:173)
`visioning 64 into the network 17.
`FIG. 6 shows a simplified timeline 70b for the alternate
`time based wireless access provisioning process 52b. The
`enhanced network access point 12 tracks power on 56 of
`wireless devices as a function of time 72. As seen in FIG. 6,
`the user activates provisioning logic 44 at the network access
`point 12, at time 84. The network access point 14 notes the
`start time 82 of the power on 56 of a wireless device 14 which
`is desired to be provisioned within the network 17. If the
`power on 56 falls within the acceptance time interval 74, the
`desired device 14 is accepted 62 (FIG. 4). As seen in FIG. 6,
`the time interval 76 for the desired device 14 properly falls
`within the acceptance interval 74, such that the provisioning
`logic 44 accepts 62 the wireless device 14, and initiates pro(cid:173)
`visioning 64.
`As further seen in FIG. 6, the network access point 14 also
`notes the start time 88 of the power on 78 of a second wireless
`device 14, which is not necessarily desired to be provisioned
`by the network access point 12, such as from an unauthorized
`device 14, or from a desired device which is not powered on
`65 within the time interval 74. When the user then activates the
`provisioning logic 44 at the network access point 12, at time
`86, the time interval 80 for the second device 14 falls outside
`
