Definitions

• This invention generally relates to the field of gaming and multimedia devices.
• the present invention is directed to a system and method of associating a wireless device to a console device.
• Wireless controllers provide players with freedom of movement by wirelessly connecting the controller to the gaming console.
• the controllers provide features such as vibration feedback, mini-joysticks, D-pad, pressure-sensitive buttons, etc. that players would find on wired controllers.
• the systems that connect wireless controllers to gaming consoles often allow multiple players to play at once on the console.
• Conventional wireless controllers are not easily managed where there may be many wireless controllers and gaming consoles operating in a LAN-type environment. This is because conventional wireless controllers are added on an ad-hoc basis, rather than in a systematic fashion. As gaming consoles move toward wireless and on-line community environments, the convention ad-hoc nature of wireless gaming will encounter difficulties.
• Systems and methods for associating a wireless device to a host The wireless device is associated to the host via a binding and discovery process.
• the binding process establishes the association.
• a unique identifier and other binding information is provided to the wireless device, which is stored in the wireless device to establish the link to the console.
• the binding information is retained in the wireless device.

• the host sends broadcast packets that are compared to the stored information in the wireless device.
• the broadcast packets are validated and authenticated to complete the discovery process.
• a visual indicator on the host and/or controller may indicate the success or failure of either the binding or discovery process.
• Binding and discovery are two individual steps in associating the wireless device to the host. Binding is preferably one-to-one with regard to wireless devices to hosts, however, the there is a one-to-many relationship of hosts to device. Discovery is performed after the device is bound to the host. Discovery may be performed even if a session has already been initiated with other wireless or wired devices.
• the wireless device will attempt to retry to connect to the host during the discovery process for a predetermined period of time. This period of time is preferably long enough to allow a user to correct any errors. If wireless device fails to connect, the wireless device will indicate the failure.

• the CPU reservation is preferably constant such that if the reserved CPU usage is not used by the system applications, an idle thread will consume any unused cycles.
• lightweight messages generated by the system applications are displayed by using a GPU interrupt to schedule code to render popup into an overlay.

• FIG. 2 there is illustrated an exemplary wireless controller 154 having a four quadrant LED indicator 156 (and enlarged view) and console 100 having a four quadrant indicator 158.
• the controller 154 communicates with the wireless adapter 148 via, e.g., a Frequency Hopping Spread Spectrum (FHSS) wireless communication link.
• the link preferably is able to extend up to 10 meters.
• the controller 154 also includes vibration feedback, mini-joysticks, pressure-sensitive buttons, etc.
• a game is shown on the screen 160.
• the console indicator 158 is shown surrounding a power button, however, other configurations may be implemented.
• Each quadrant of the ring may be illuminated by an LED, which may be either a single color or bi-colored to illuminate in plural colors. As will be described below, the quadrants may be illuminated in patterns indicating the notifications, system status, binding and discovery.
• each controller is logically "bound" to a single console 100 so that a link is established with only that console 100.
• a controller 154 is not bound to more than one console 100 at a time. Binding is the process by which a console 100 transmits information to a controller 154 that will enable that controller to establish a link with the console 100. Once "bound" to a console 100, the controller 154 attempts to establish a link with the console 100 to which it is bound whenever the controller 154 is turned on.
• There are four virtual controller ports on the console 100 referred to herein as "Vports." The Vports represent the active game controllers connected to the console 100, either wired or wirelessly.
• the numbered Vports are automatically assigned to controllers in the order they are connected to the console 100. Each Vport is represented by a quadrant of the LED indicator 156 and the console indicator 158. Thus, “discovery” is the process during which a wired or wireless game device is recognized by the console 100, assigned a Vport, and made available for game play.
• the acts of "binding" and “discovery” are preferably two distinct, but related acts.
• the act of binding is initiated by pressing the BIND or CONNECT buttons on the controller and console. Once bound, the controller will begin the discovery process, and if successful, will be assigned the first available Vport, which in this case is Vport 1 as described. If one to three controllers had previously been bound and discovered, then the next controller discovered would be assigned Vport 2, 3, or 4 respectively. If, four controllers were already discovered, then the binding process could still be performed, however no Vport would be available to assign, so the controller would not be assigned a Vport, however it would still be bound to the console and available to be discovered if one of the other four controllers were either turned off or bound to a new console.
• Binding or connecting is an event that allows new controllers 154 to be added to the console (host) 100.
• each wireless controller 154 is preferably added to a single console at a time. It is further preferable that the single console is the only console to which the wireless controller 154 is connected at a particular time. For most users the binding process is performed only one time per console, unless the user wants to use the same controller with another console. Unbinding controllers from a console 100 is not necessary, as the number of controllers that may be bound to a console is unlimited.
• the binding or connecting process is initiated by pressing a CONNECT button on the console 100 (step 200) and the CONNECT button on wireless controller 154 (step 226).
• each CONNECT button When each CONNECT button is pressed, each device will stay in this mode until the binding is complete or times-out. Each device will flash an LED pattern to indicate the beginning of the binding process (steps 202, 228).
• the console 100 will send a broadcast packet with a binding bit and its FHSS hopping polynomial in the next available slot in the broadcast packet (steps 204, 206).
• the controller 154 selects a channel and listens for the broadcast packet from the console 100 (step 230).
• the controller 154 will have received the binding packet and can be connected to the console 100. During this period the controller 154 will check to see if the binding packet was received, and change channels and wait for the binding packet on another channel, if necessary (steps 232, 240, 242). Meanwhile, during this period, the console 100 will listen for a binding request packet from the controller 154 (steps 208, 210, 216) The console 100 and controller 154 preferably timeout and exit from the binding mode if no binding information is exchanged between them within 20 seconds (steps 218, 244). The LEDs may be flashed to indicate the failure (steps 220, 246).
• binding packets that contain binding information and verifications are exchanged (steps 212, 234).
• the controller 154 stores the ID of the console 100 and a FHSS hopping polynomial on an EEPROM provided within the controller 154 (step 236).
• the LEDs may be flashed to indicate the successful binding (steps 214, 238) and the binding process is complete (steps 222, 248).
• the controller 154 receives a unique console identification (ID) code and hopping polynomial and stores them in the wireless controller 154. This information is used to establish a link with the console 100 when it is turned on. In terms of the wireless controller, turning on the controller 154 is equivalent to "plugging in” a wired controller to the console.
• ID console identification
• the binding information once stored on the wireless controller 154 is preferably retained even if the batteries or rechargeable battery pack is removed and also throughout all the discharge/charge cycles. The user, therefore, will not need to re-bind between battery changes or charge cycles with play/charge cable.
• the controller 154 when the controller 154 is bound to a second console, the user will need to re-bind to the first console as the ID and FHSS hopping polynomial will be that of the second. Only one console ID and hopping polynomial can be stored to the controller at a time.
• the binding process above does not halt game play on the console 100.
• any controller can bind and join without interrupting the game or requiring the play to stop or impacting any voice or data communication of the other controllers.
• the binding process may also be initiated by connecting a wireless controller 154 to console 100 using play/charge cable. In this mode, the binding packets are exchanged via the USB cable.
• the console 100 host sends its wireless module device ID and hopping polynomial to the controller 154, as in the wireless scenario.
• controller 154 Upon receiving this information, controller 154 stores them into its EEPROM, establishes the RF link to console 100 automatically and turn on the controller LED indicator (see, Fig. 2) to indicate the connection status.
• binding process Some additional features with respect to the binding process are as follows.
• the dedicated CONNECT or BINDING button on the controller 154 or on the console 100 does not power up the controller or console when pressed.
• the CONNECT or BINDING button should be pressed and held for more than 0.75 sec. for binding process to be initiated. This is to prevent inadvertent actuation of the button on the controller and console.
• Binding is a one-to-one event. Pressing the binding button will bind one controller at a time. To bind the next controller, a subsequent user must push the bind button on the console 100 subsequent time before binding or connecting will take place.
• a status notification screen may display the binding and discovery process (binding...bound....discovered) to provide feedback to the user.
• the binding process may be terminated on the wireless controller 154 by pressing the CONNECT button a second time within the 20 sec allocated time.
• the wireless controller will retain all the information such as ID code of previous console if it is not successful.
• the entire process of binding is preferably completed within 6.5 sec.
• the discovery process enables the wireless controller 154 to join the game session. During the discovery process, device authentication is also performed. The discovery process can be done before or during the game session and it takes place after the device is bound to a console. While the console 100 is in the binding mode, the device discovery process is preferably not enabled.
• the host (console 100) performs the exemplary processes illustrated in Fig. 5.
• a host (console) broadcast packet is used for discovery process.
• the console 100 sends out the broadcast packets twice in every frame (steps 250, 252).
• the console 100 checks the data in the first available slot (step 254). If a valid data link control packet is detected, the console 100 marks that slot occupied and decodes the link control packet (steps 256, 258). If the console 100 does not detect the link control packet, it will send out a discovery complete packet and update its free slot information (step 270) and return to step 252.
• the console 100 If there is a valid link control packet, the console then exchanges the link control packets with controller 154 or other wireless device and acknowledges the link control packets (steps 260, 262). Next, the console 100 initiates an authentication process by sending the transport packets to the wireless controller 154 (step 264). The console 100 waits for the authentication response, validates the response, and sets the flag in its discovery complete packet to indicate the success/failure of the discovery (steps 266, 268). The console 100 completes the process by updating its free slot information in the broadcast packet (step 270) and returns to step 252.
• controller 154 When controller 154 (or any wireless device) joins the game session, it performs the exemplary sequence of Fig. 6. Initially, the controller 154 indicates, via the LEDs, that it is entering the discovery mode (steps 272, 274). Next, the controller 154 selects one channel from the total channel list and listens for the broadcast packet (steps 276, 277). The duration that the device stays on the same hop frequency is approximately 164 ms to provide enough time for host to go through all its possible channels. If no broadcast packet is detected or the packet can not be successfully decoded, the controller 154 moves to another channel and repeats steps 276 and 277.
• the controller 154 device After receiving the broadcast packet, the controller 154 device performs a host ID validation to join the correct network hosted by its bound host, i.e., console 100.
• the controller 154 adjusts its timing to match the host 8 ms frame timing and frame counter (steps 278-284).
• the controller 154 checks the broadcast packet and finds an available slot (step 286).
• the controller 154 updates its hop channels based on the FHSS/AFH information in broadcast packet and takes the first available slot (step 288). * If there is not a match of the host ID at step 284, then the LEDs are illuminated to indicate a failure at step 318 and the process ends (step 320).
• the controller sends its link control packet in the next frame (steps 290, 292). If it does not detect a broadcast packet, it will back off a random amount of frames at step 294 and start step 288 again.
• the controller 154 checks its slot in the host broadcast packet for the ACK bit for the link control packet it sent (step 296).
• the controller 154 waits for host transport packets and forwards them to a security mechanism (steps 298-304). If they are not received, then the controller LEDs are illuminated to indicate that a time out period for receipt has elapsed (step 302). The controller 154 polls the security mechanism and waits for the status of the authentication (step 306). Once complete, the controller 154 will forward the status to console 100 via transport packets (steps 308, 310). The controller 154 will not send any data until the authentication is complete (step 312). The controller 154 completes the discovery process and sets a flag LED based on the flag set by the host for the discovery success/failure (steps 314-320).
• the controller 154 will preferably try 20 times to connect to the console 100. If it fails to connect, the controller 154 will flash an error message of "no communication" using its LEDs. Each retry may last up to 15 s, and the time from retry fail to new retry start is delayed between 250 ms to 1520 ms. This advantageously provides a retry time for up to 330 s, which provides the user time to correct errors, etc.
• any input such as button press or trigger/thumbstick movement causes the controller 154 to initiate its discovery process automatically.
• FIGs. 7 and 8 there is a visualization of the binding and discovery processes and how the LED indicator 156 and the console indicator 158 visually convey the processes to players.
• the controller has been powered on and the BIND button on the console 100 and the controller have been pressed.
• the discovery process takes place. Because this is the first controller to be discovered by the console 100, it is associated with Vport 1 and the top left quadrant of the indicators 156 and 158 will illuminate to signal the connection.
• the other quadrants of indicator 158 are illuminated in succession.
• two quadrants of the indicator 158 will illuminate, and so on up to four controllers and four quadrants. It is noted that while additional quadrants are successively illuminated on the console, only a single quadrant is illuminated on any single controller at a time.
• the position of the quadrant preferably corresponds to the Vport as follows:
• the position of the players on the screen correspond to the quadrant assigned to their particular controller.
• Vports are preferably assigned in ascending order (1 through 4), according to the following rules: - If the system is powered up by a controller, that controller (wired or wireless) is assigned Vport 1.
• USB Port A directly plugged into USB Port A (e.g., controller 142(1)).
• USB Port B directly plugged into USB Port B (e.g., controller 142(2)).
• Vports are vacated as controllers are unplugged or powered off.
• a wireless controller that is powered off is treated the same as a wired controller that is unplugged from the console 100.
• the console 100 will assign additional wired and wireless controllers to available Vports in the order in which they are connected or powered up.
• the game will be notified when a controller is unplugged.
• the game will pause and display a disconnect message.
• the game also notifies the console 100 that the vacated Vport is the next to be repopulated should a controller be reconnected. Should subsequent disconnects occur, the console notifies the game and the game reports back with the next Vport to populate.
• the console maintains in a Last-In- First-Out stack for the next Vport assignment requested by the game.
