FIG. 1 is a conceptual diagram illustrating an example of a hardware implementation for an apparatus 100 employing a processing system 114. In accordance with various aspects of the present disclosure, an element, or any portion of an element, or any combination of elements may be implemented with a processing system 114 that includes one or more processors 104. For example, in various aspects, the apparatus 100 may represent any one or more of a wireless dockee, a wireless docking host, and/or a peripheral device. Examples of processors 104 that may be utilized in an apparatus 100 include microprocessors, microcontrollers, digital signal processors (DSPs), field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionality described throughout this disclosure.
In this example, the processing system 114 may be implemented with a bus architecture, represented generally by the bus 102. The bus 102 may include any number of interconnecting buses and bridges depending on the specific application of the processing system 114 and the overall design constraints. The bus 102 links together various circuits including one or more processors (represented generally by the processor 104), a memory 105, and computer-readable media (represented generally by the computer-readable medium 106). The bus 102 may also link various other circuits such as timing sources, peripherals, voltage regulators, and power management circuits, which are well known in the art, and therefore, will not be described any further. A bus interface 108 provides an interface between the bus 102 and a transceiver 110. The transceiver 110 provides a means for communicating with various other apparatus over a transmission medium. Depending upon the nature of the apparatus, a user interface 112 (e.g., keypad, display, speaker, microphone, joystick) may also be provided.
The processor 104 is responsible for managing the bus 102 and general processing, including the execution of software stored on the computer-readable medium 106. The software, when executed by the processor 104, causes the processing system 114 to perform the various functions described infra for any particular apparatus. The computer-readable medium 106 may also be used for storing data that is manipulated by the processor 104 when executing software.

The dockee 230 may be any suitable device capable of wirelessly connecting to the wireless docking environment 306 utilizing any suitable communication protocol, which may include but is not limited to IEEE 802.11 “Wi-Fi.” By connecting to the wireless docking environment 306, the dockee 230 may be capable of connecting directly or indirectly to each of the peripherals 210 that are part of the wireless docking environment 306.
The wireless docking environment 306 is a group of one or more physical devices, including one or more wireless docking hosts 220 and one or more peripherals 210. A wireless docking environment 306 can take any suitable configuration or topology, for example, including nothing more than a wireless docking host 220, or additionally including one or more peripherals 210.
The peripherals 210 may represent logical peripheral functions. In general, a peripheral function may be any I/O function implemented in a wireless docking host 220 that can be made available to a wireless dockee 230 through any of various suitable wireless interfaces, or any I/O function in an external peripheral device 210 that can be made available to the wireless dockee 230 through the wireless docking host 220, where the external peripheral device may be directly connected to the wireless docking host 220.

The wireless docking host 220 may be any suitable device capable of connecting to the wireless dockee 230 and one or more peripherals 210. For example, a wireless docking host 220 may make available to a wireless dockee 230 peripheral functions on external peripherals 210 that are connected to the docking host 220 directly, as well as peripheral functions the wireless docking host 220 itself may implement (e.g., a display).
The docking host 220 may provide different docking experiences or docking environments 306 to different dockees 230. For example, at a given time a dockee 230 may have a particular need for certain peripheral functions, and upon learning of this need, the docking host 220 may therefore provide a corresponding docking environment 306 for that dockee.
One example of a way for a docking host 220 to provide these capabilities to different dockees 230 is for the docking host 220 to preconfigure multiple docking environments 306. That is, multiple groups of peripherals 210 can be preconfigured at the docking host 220, e.g., by randomly selecting groups of available peripherals 210 or by selecting certain peripherals to be grouped together. Here, each group may be a logical group including suitable peripherals 210, which may be manually or automatically configured with the docking host 220.
In this example, the docking host 220 may group its attached and/or wirelessly paired peripherals 210 into multiple hierarchical groups and enable each dockee to use one group. For example, assume that a particular docking host 220 has peripherals A-G available. Here, peripherals A, B, and C may be grouped together into a first group, and peripherals D, E, F, and G may be grouped together into a second group. This way, the groups may be disjoint groups of peripherals. In another example, peripherals A, B, and C may be grouped together into a first group, and peripherals C, D, and E may be grouped together into a second group. This way, the groups may have some intersection or overlap of peripherals.
With a hierarchical grouping, separate groups of peripherals might be disjoint groups, and separate groups might have a common parent. For the common parent, peripherals A, B, C, D, E, and F might be a parent group in the hierarchy, and at the next level of the hierarchy, groups might include, for example, peripherals A, B, and C as a first group; and peripherals D, E, and F as a second group. By utilizing such groups of peripherals, each such group can be considered a separate wireless docking environment 306 as discussed above. That is, a particular wireless docking host 220 may be capable of providing any from a plurality of wireless docking environments 306 to a particular wireless dockee 230, each wireless docking environment 306 including a different group of peripherals that may be one of a plurality of preconfigured hierarchical groups.
As introduced above, wireless chargers have been known in the art, and provide the capability to charge battery-powered devices without any physical attachment or plug between the battery-powered device and the wireless charger. For example, inductive charging may be utilized, wherein energy is transferred from a primary coil in a wireless charger to a secondary coil in a battery-powered device by way of inductive coupling between the respective coils at each device. In the literature, such devices might additionally be referred to as inductive charging or contactless energy transfer.
One or more aspects of the present disclosure relate to the use and performance of a wireless docking environment 306 that includes a wireless charger. For illustrative but nonlimiting purposes, the functionality of a wireless docking environment including a wireless charger is described herein below in two specific examples. In the first example, illustrated in FIGS. 4-6, the wireless charger itself is integrated as a unit with the wireless docking host. In the second example, illustrated in FIGS. 7-10, the wireless charger is a peripheral, communicatively coupled with a separate docking host.
Wireless Docking Host-Charger
FIG. 4 is a simplified schematic diagram illustrating an aspect of the disclosure that includes a host-charger 402. Here, the host-charger 402 may include a wireless docking host 220, as described above in relation to FIG. 2, wherein the host function circuitry 224 may include, at least in part, wireless charging circuitry such as an inductive charging coil configured to enable wireless charging of a proximate dockee.
As seen at FIG. 4, an exemplary docking environment may be configured wherein the host-charger 402 is connected to a monitor/display 404 by way of a physical cable, and a keyboard 406 and mouse 408 are wirelessly connected to the docking host 402. With this exemplary configuration, the display 404, keyboard 406, and mouse 408 may be peripherals 210 in a docking environment 306 managed by the host-charger 402. As will be discussed in further detail below, a handset/dockee 410 may land upon the host-charger 402 for charging its battery, as well as for entering into a docking session with the illustrated docking environment. Here, the dockee 410 may be the same as the dockee 230 described above in relation to FIG. 2.
FIG. 5 is a block diagram illustrating additional detail of one example of a host-charger 402. Here, the host-charger 402 includes wireless charging circuitry 502, a memory 504, a processor 506, a display interface 508 for providing image information to the display 404, a wireless peripheral interface 510 for communicating with one or more wireless peripherals such as the keyboard 406 and/or the mouse 408, and a wireless dockee interface 512 for communicating with one or more wireless dockees 410, 230. In one example, the processor 506 and the memory 504 may be the same as the corresponding processor 221 and memory 223 illustrated in the docking host 220 in FIG. 2. Moreover, the wireless charging circuitry 502 may be included in the host function circuitry 224; and the display interface 508, the wireless peripheral interface 510, and the wireless dockee interface 512 may be the same as the communication interface 222.
FIG. 6 is a call flow diagram illustrating an example of a sequence of events that may occur utilizing the above-described host-charger 402 in the docking environment illustrated in FIG. 4 in accordance with an aspect of the disclosure.
First, a user with a handset, which may be configured as a wireless dockee 410, may enter the vicinity of the host-charger 402. Here, at a time prior to a placement of the dockee 410 onto the host-charger 402, the dockee 410 may detect the existence of the wireless docking environment hosted by the host-charger 402, and/or conduct various discovery operations for discovering or identifying services, peripherals, or other characteristics of the docking environment, e.g., by utilizing the communication interface 232. This is illustrated with pre-association discovery signal 602 between the dockee 410 and wireless docking host function of the host-charger 402.
When the dockee 410 lands on the host-charger 402, a wireless charger coupling 604 may be established between the wireless charging circuitry 502 at the host-charger 402 and the wireless charging circuitry 235 at the dockee 410. In an aspect of the disclosure, the establishment of this wireless charger coupling 604 may be utilized as a trigger, to establish a docking session between the dockee 410 and the host-charger 402. Here, if it is the first time that a docking session is to be established between this dockee 410 and host-charger 402, an initial pairing operation may be undertaken, for establishing an authentication of credentials between the dockee 410 and the host-charger 402 and an association between the devices.
To establish the pairing, in one aspect of the disclosure, at 606 the dockee 410 may automatically acquire credential information upon landing on the host-charger 402. For example, the credential information may be transmitted from the host-charger 402 to the dockee 410 utilizing a suitable communication interface. Here, the credential information may be transferred from the host-charger 402 to the dockee 410 utilizing the wireless dockee interface 512 (e.g., utilizing BTLE communication). In another example, the credential information may be transferred from the host-charger 402 to the dockee 410 utilizing the wireless charging circuitry 502, which may be configured for near-field communication (NFC). Once the credentials are obtained at the dockee 410, at 608, a dockee-initiated authentication/association operation may be undertaken between the dockee 410 and the host-charger 402, wherein the dockee 410 utilizes the credential information received at 606.
In another aspect of the disclosure, to establish the pairing, the dockee 410 may perform a Wi-Fi Simple Configuration (WSC) procedure. Here, at 610 the wireless charging function within the host-charger 402 may communicate, internally, with the integrated wireless docking host function within the host-charger 402, to signal the docking intent of the dockee 410. At this point, at 612 a docking host-initiated authentication/association operation may be undertaken between the dockee 410 and the host-charger 402.
Once the pairing is completed, at 614, a wireless connection may be established between the communication interface 232 at the dockee 410 and the wireless dockee interface 512 at the host-charger 402, corresponding to the initiation of a docking session. Here, the user of the dockee 410 may begin utilizing the peripherals (e.g., the keyboard 406, the mouse 408, and the display 404) corresponding to the docking environment.
During the duration of the docking session, at any time the user of the dockee 410 may pick up the dockee 410, e.g., for a phone call, without implementing an undocking procedure. That is, even though the dockee 410 is not landed on the host-charger 402, in an aspect of the disclosure, the wireless connection between the communication interface 232 at the dockee 410 and the wireless dockee interface 512 at the host-charger 402 may be maintained. During this time, while the dockee 410 is removed from the host-charger 402, it is possible that another user may land their own handset onto the host-charger 402. In one example, the wireless charging circuitry 502 at the host-charger 402 may continue to function, enabling this second handset to be charged; however, in this example, no docking session need be established between the host-charger 402 and the second handset. Rather, the docking session may be maintained between the dockee 410 and the host-charger 402. Thus, if and when the dockee 410 re-lands on the host-charger 402, a wireless charger coupling may be re-established, re-enabling charging of the dockee 410 while the docking session is maintained.
To un-dock the first handset 310 from the docking session, in one aspect of the disclosure, shown at 616, the user of the dockee 410 may implement explicit instructions to un-dock from the host-charger 402, e.g., utilizing the user interface 234 at the dockee 410. Of course, in another example, such an explicit instruction to terminate the docking session may be implemented utilizing one or more peripherals of the docking environment, such as the keyboard 406, the mouse 408, and/or the display 404.
In another aspect of the disclosure, the user may pick up their handset (i.e., the dockee 410) and leave the vicinity of the host-charger 402, causing a ceasing of communication between the communication interface 232 at the dockee 410 and the wireless dockee interface 512 at the host-charger 402. According to an aspect of the disclosure, this traffic inactivity may eventually result in the expiration of a traffic inactivity timer at the host-charger 402. As a result, the host-charger 402 may determine that there is no traffic activity for a certain length of time (e.g., a predetermined length of time), and accordingly, at 618 a docking host-initiated undocking procedure may commence, terminating the docking session between the dockee 410 and the host-charger 402.
Wireless Charger as a Peripheral
FIG. 7 is a simplified schematic diagram illustrating another aspect of the disclosure that includes a wireless charger 702 that functions as a peripheral device in a docking environment. For example, the wireless charger 702 may be the same as the peripheral 210 illustrated in FIG. 2, wherein the peripheral function circuitry 214 includes, at least in part, wireless charging circuitry as described above.
In a further aspect of the disclosure, a docking host may be embedded in, or otherwise attached or coupled to a monitor/display 704. That is, referring now to FIG. 8, a wireless docking host-display 704 according to an aspect of the disclosure may include not only a display device 802, but additionally, a memory 804 and processor 806 for implementing the functionality of the docking host; a wireless dockee interface 808 for communication with one or more dockees such as a dockee 710 during a docking session; and a wireless peripheral interface 810 for communicating with one or more peripherals, such as the wireless charger 702, a keyboard 706, and a mouse 708. In one example, the processor 806 and the memory 804 may be the same as the corresponding processor 221 and memory 223 illustrated in the docking host 220 in FIG. 2. Moreover, the wireless dockee interface 808 and the wireless peripheral interface 810 may be the same as the communication interface 222. Of course, this is merely one example described in detail for illustrative purposes, and in various examples within the scope of the disclosure, the docking host may be communicatively coupled with the display in any suitable fashion known to those of ordinary skill in the art.
Referring once again to FIG. 7, an exemplary docking environment may be configured wherein the host-display 704 may host a docking environment that includes, as peripherals, the wireless charger 702, a keyboard 706, and a mouse 708. As will be discussed in further detail below, the handset/dockee 710 may land upon the peripheral wireless charger 702 for charging its battery, as well as for entering into a docking session with the illustrated docking environment.
In accordance with some aspects of the disclosure, at least two different use cases may exist for the establishment of a docking environment by landing the dockee 710 on the wireless charger 702. In a first example, as illustrated in FIG. 9, the wireless charger 702 may be used to help the dockee 710 to dock with the docking host-display 704. In a second example, the use of the wireless charger 702 by the dockee 710 may need to be authorized by the docking host.
FIG. 9 is a call flow diagram illustrating a first example of a sequence of events that may occur utilizing the above-described wireless charger 702 in the docking environment illustrated in FIG. 7 in accordance with an aspect of the disclosure. In this example, an initial docking session is utilized to establish the wireless charger 702 as a peripheral in a wireless docking environment offered by this wireless docking host (i.e., the host-display 704), and as an illustrative example, the wireless charger 704 is utilized by the dockee 710 for charging in a subsequent docking session.
As a peripheral device 210, the wireless charger 702 may include a communication interface (e.g., the communication interface 212) for communicating with the wireless docking host-display 704. Further, the host-display 704 may be capable of informing the dockee 710 that the wireless charger 702 is one of its peripherals, e.g., by way of its wireless dockee interface 808. Still further, the dockee 710 may be enabled to identify a coupled wireless charger 702 with its detected wireless docking environment, e.g., as communicated to the dockee 710 by way of the host-display 704. Further, the dockee 710 may include functionality to couple with the wireless charger 702, as described below, as a trigger to establish the docking session.
Referring now to the call flow diagram of FIG. 9, the wireless charger 702 is shown being paired with the docking host 704 as a peripheral in a docking environment, as illustrated at 902. At this time, an initial docking session may be established. That is, the user in possession of the dockee 710 may enter the vicinity of the wireless charger 702. Here, the dockee 710 may detect the existence of the wireless docking environment hosted by the host-display 704, wherein, as described above, the wireless docking environment includes the wireless charger 702 as a peripheral. Thus, at 904, a pre-association discovery phase may occur between the docking host 704 and the handset 710. As described above, the pre-association discovery phase may include the dockee 710 detecting the existence of the wireless docking environment hosted by the host-display 704, and/or conducting various discovery operations for discovering or identifying services, peripherals, or other characteristics of the docking environment, e.g., by utilizing the communication interface 232.
Here, since this initial docking session establishment is the first time that a docking session is to be established between this dockee 710 and this host-display 704, an initial pairing operation may be undertaken. To this end, an authentication and association operation 906 may be undertaken between the dockee 710 and the host-display 704 for establishing an authentication of credentials between the dockee 710 and the host-display 704 and an association between the devices.
Once the docking session 908 is established, the dockee 710 may record the wireless charger 702 as a peripheral in the wireless docking environment offered by the host-display 704, and thereby the dockee 710 may begin using the peripherals connected to the docking host (e.g., the keyboard, the mouse, the display, and the wireless charger 702).
At 910, the dockee 710 may undock from the host-display 704 as described above, e.g., either by the user picking up the dockee 710 and leaving the vicinity of the docking host 704 for a predetermined length of time, or by an explicit undocking procedure undertaken by the user of the dockee 710.
In an aspect of the disclosure, with this docking environment information stored at the dockee 710, the docking environment including the wireless charger 702 may be a persistent docking environment, the subsequent establishment of which may be triggered by the landing of the dockee 710 on the wireless charger 702, as described below.
In this example, the user may subsequently approach the vicinity of the wireless charger 702 with the dockee 710, at which time a pre-association discovery operation 912 may again take place between the dockee 710 and the host-display 704, as described above. Here, because the dockee 710 and the host-display 704 have previously established a docking session, as described above, the wireless charger 702 is recorded at the dockee 710 as a peripheral in the wireless docking environment. Thus, once the dockee 710 lands on the wireless charger 702, such that the wireless charger coupling 914 occurs between the dockee 710 and the wireless charger 702, the dockee 710 may initiate a dockee-triggered authentication and association operation 916, utilizing credential information stored at the dockee 710 during the initial docking session, described above. At this time, the docking session 918 may commence between the dockee 710 and the docking host 704.
Those of ordinary skill in the art will recognize that the above-described example, including the utilization of a persistent docking environment, is merely illustrative in nature and is not intended to be limiting on the paradigm of utilizing the landing of the dockee 710 upon the wireless charger 702 as a trigger to initiate the establishment of a docking session. That is, the landing of the dockee 710 on the wireless charger 702 may trigger the establishment of any suitable docking session, including but not limited to an initial docking session, a subsequent docking session, a persistent docking session, etc.
FIG. 10 is a call flow diagram illustrating a second example of a sequence of events that may occur in use of the wireless charger 702 in the docking environment illustrated in FIG. 7 in accordance with another aspect of the disclosure.
In this example, the wireless charger 702 may be configured to perform an authentication procedure with the dockee 710 before enabling a wireless charging operation. To this end, as described below, the dockee 710 may enter into a docking session utilizing a docking environment that includes the wireless charger 702 as a peripheral, prior to enabling the wireless charger 702 to charge the dockee 710. That is, in accordance with an aspect of the disclosure, a charging function corresponding to the wireless charger 702 may be disabled until such time as the wireless dockee 710 enters into a docking session with the wireless docking host-display 704. In this way, the wireless docking host-display 704 may be enabled to act as a credential registrar for the wireless charger 702, in order to authenticate and authorize the dockee 710 to use the wireless charger 702.
Finally, in some examples, the wireless charger 702 may be required to check with the wireless docking host 704 to determine the handset's docking status, to determine whether to continue charging the handset 710.
Referring now to the call flow diagram of FIG. 10, the wireless charger 702 is shown being paired with the docking host 704 as a peripheral in a docking environment, as illustrated at 1002. At this time, a docking session may be established. That is, the user in possession of the dockee 710 may detect the existence of the wireless docking environment hosted by the host/monitor 704, wherein, as described above, the wireless docking environment includes the wireless charger 702 as a peripheral. Thus, at 1004, a pre-association discovery phase may occur between the docking host 704 and the handset 710. As described above, the pre-association discovery phase may include the dockee 710 detecting the existence of the wireless docking environment hosted by the host-display 704, and/or conducting various discovery operations for discovering or identifying services, peripherals, or other characteristics of the docking environment, e.g., by utilizing the communication interface 232.
At 1006, an authentication and association operation may be undertaken between the dockee 710 and the host-display 704 for establishing an authentication of credentials between the dockee 710 and the host-display 704 and an association between the devices.
Once the docking session 1008 is established, the user of the dockee 710 may begin utilizing the peripherals connected to the docking host 704, such as the keyboard, mouse, and display, as well as the wireless charger. In an aspect of the disclosure, to provide functionality at the wireless charger 702, at 1010, after the user lands the dockee 710 on the wireless charger 702, a wireless charger link authentication operation may be undertaken between the wireless charger 702 and the dockee 710. For example, communication between the dockee 710 and the wireless charger 702 may take place upon landing on the wireless charger 702, wherein the communication may include NFC or other suitable communication. This communication may include, for example a request from the dockee 710 for authentication to utilize the wireless charging function.
Here, at 1012, authentication utilizing the host-display 704 as a credential registrar may be undertaken, wherein, for example, the wireless charger 702 may request credential information corresponding to the dockee 710 from the host-display 704. Here, the host-display 704 may provide credential information corresponding to the dockee 710 to the wireless charger 702, indicating that the wireless charging function at the wireless charger 702 is authorized for the dockee 710.
Once the dockee 710 has been authenticated to the wireless charger 702, a wireless charger coupling 1014 between the wireless charger 702 and the dockee 710 may be established, such that, at 1016, the dockee 710 may charge its battery.
FIGS. 11-14 are flow charts illustrating certain exemplary processes for establishing a docking session with a docking environment that includes a wireless charger, in accordance with various aspects of the present disclosure.
For example, FIG. 11 describes a process that may be operable by a dockee 410 and a docking host-charger 402 as illustrated in FIG. 4. In the illustrated process 1100, at step 1102, as the dockee 410 approaches the wireless docking host-charger 402, by virtue of their respective communication interfaces (e.g., Wi-Fi, BTLE, or any other suitable wireless communication technology), a pre-association discovery process may take place, wherein the dockee 410 may detect the existence of the wireless docking environment hosted by the host-charger 402, and/or conduct various discovery operations for discovering or identifying services, peripherals, or other characteristics of the docking environment. Either during this discovery procedure, or after its completion, at step 1104 the dockee 410 may land on the wireless charger portion of the host-charger 402. For example, after entering the room in which the host-charger 402 is located, the user may place the dockee in their possession onto the wireless charger portion of the host-charger 402, e.g., with an intent to charge the battery of the dockee, and/or to utilize one or more peripherals in the associated docking environment.
In response to the landing of the dockee 410 on the host-charger 402, at step 1106 the wireless docking host-charger 402 may transmit credential information to the dockee 410. In one example, the wireless docking host-charger 402 may utilize its wireless dockee interface 512 to transmit the credential information to the dockee 410. For example, the pre-association discovery phase described above at step 1102 may establish a channel on which the credential information may be carried. In another example, the wireless docking host-charger 402 may utilize its wireless charging circuitry 502, which may be configured for NFC, to transmit the credential information to the dockee 410.
At step 1108, the dockee 410 may transmit the credential information (or information corresponding thereto) back to the wireless docking host-charger 402, and at step 1110, the wireless docking host-charger may dock the dockee 410 with a suitable docking environment in accordance with the received credential information. That is, by utilizing the credential information received at step 1106, the dockee 410 may initiate an authentication/association operation to establish a secure docking session with the wireless docking host-charger 402.
FIG. 12 describes another process that may be operable by a dockee 410 and a docking host-charger 402 as illustrated in FIG. 4. In the illustrated process 1200, at step 1202, the as the dockee 410 approaches the wireless docking host-charger 402, by virtue of their respective communication interfaces (e.g., Wi-Fi, BTLE, or any other suitable wireless communication technology), a pre-association discovery process may take place, wherein the dockee 410 may detect the existence of the wireless docking environment hosted by the host-charger 402, and/or conduct various discovery operations for discovering or identifying services, peripherals, or other characteristics of the docking environment. Either during this discovery procedure, or after its completion, at step 1204 the dockee 410 may land on the wireless charger portion of the host-charger 402. For example, after entering the room in which the host-charger 402 is located, the user may place the dockee in their possession onto the wireless charger portion of the host-charger 402, e.g., with an intent to charge the battery of the dockee, and/or to utilize one or more peripherals in the associated docking environment.
In response to the landing of the dockee 410 on the host-charger 402, at step 1206, wireless charging circuitry 502 at the host-charger 402 may couple with a wireless charging interface at the dockee 410. Further, at step 1208, wireless charging circuitry 502 at the wireless docking host-charger 402 may transmit information indicating a docking intent of the dockee 410 to docking circuitry (e.g., the processor 506) at the wireless docking host-charger 402. For example, any suitable information may indicate the docking intent of the dockee 410, such as an information element configured to indicate the docking intent and/or other information corresponding to the dockee 410, or any suitable symbol that the host-charger 402 may take as indicating the docking intent. Thus, at step 1210, the dockee 410 may dock with a docking environment in accordance with the docking intent of the dockee 410.
FIG. 13 describes a process that may be operable by a dockee 710 and a wireless docking host (e.g., the host-display 704) as illustrated in FIG. 7. In the illustrated process 1300, at step 1302, a pairing may be established between a wireless charger 702 and the wireless docking host-display 704. Accordingly, the docking host may have the wireless charger 702 available for use as a peripheral in a suitable docking environment.
At step 1304, the wireless dockee 710 may establish a first (initial) docking session with the wireless docking host-display 704. As described above in relation to FIG. 9, the establishment of the initial docking session may include pre-association discovery, authentication and association between the dockee 710 and the docking host 704, and docking. Accordingly, at step 1306, the dockee 710 may store credential information in accordance with the docking session. Later, at step 1308, based on the user leaving with the dockee 710, causing the expiration of an inactivity timer, or the user explicitly terminating the docking session by way of an instruction, the initial docking session may terminate.
At step 1310, the user may return with dockee 710, and may land the dockee 710 on the wireless charger, thereby establishing a coupling with the wireless charger utilizing the wireless charging interface at the dockee. At step 1312, the dockee 710 may transmit the stored credential information to the docking host 702 in response to the landing on the wireless charger. For example, the dockee 710 may utilize its wireless docking host interface for the transmission of the stored credential information. Thereby, the dockee 710 may dock with the docking environment that includes the wireless charger as a peripheral, in accordance with the transmitted credential information.
FIG. 14 describes another process that may be operable by a dockee 710 and a wireless docking host (e.g., the host-display 704) as illustrated in FIG. 7. In the illustrated process 1400, at step 1402, a pairing may be established between a wireless charger 702 and the wireless docking host-display 704. Accordingly, the docking host may have the wireless charger 702 available for use as a peripheral in a suitable docking environment.
At step 1404, the wireless dockee 710 may establish a docking session with the wireless docking host-display 704. As described above in relation to FIG. 10, the establishment of the docking session may include pre-association discovery, authentication and association between the dockee 710 and the docking host 704, and docking.
Once the docking session is established, at step 1406, the dockee 710 may land on the wireless charger 702. Accordingly, at step 1408, the wireless charger 702 may transmit information to the docking host-display 704 indicating that the dockee 710 landed on the wireless charger 702. In various examples, the information transmitted from the wireless charger 702 to the docking host-display 704 may be carried over the air utilizing any suitable communication interface, including but not limited to a wireless dockee interface 808 configured for NFC, or a wireless peripheral interface 810 configured for Wi-Fi or BTLE communication.
