The disclosure is related to increasing power savings through intelligent synchronizing of data.
The Internet is a global system of interconnected computers and computer networks that use a standard Internet protocol suite (e.g., the Transmission Control Protocol (TCP) and Internet Protocol (IP)) to communicate with each other. The Internet of Things (IoT) is based on the idea that everyday objects, not just computers and computer networks, can be readable, recognizable, locatable, addressable, and controllable via an IoT communications network (e.g., an ad-hoc system or the Internet).
A number of market trends are driving development of IoT devices. For example, increasing energy costs are driving governments' strategic investments in smart grids and support for future consumption, such as for electric vehicles and public charging stations. Increasing health care costs and aging populations are driving development for remote/connected health care and fitness services. A technological revolution in the home is driving development for new “smart” services, including consolidation by service providers marketing ‘N’ play (e.g., data, voice, video, security, energy management, etc.) and expanding home networks. Buildings are getting smarter and more convenient as a means to reduce operational costs for enterprise facilities.
There are a number of key applications for the IoT. For example, in the area of smart grids and energy management, utility companies can optimize delivery of energy to homes and businesses while customers can better manage energy usage. In the area of home and building automation, smart homes and buildings can have centralized control over virtually any device or system in the home or office, from appliances to plug-in electric vehicle (PEV) security systems. In the field of asset tracking, enterprises, hospitals, factories, and other large organizations can accurately track the locations of high-value equipment, patients, vehicles, and so on. In the area of health and wellness, doctors can remotely monitor patients' health while people can track the progress of fitness routines.

The access point 125 may communicate with IoT devices 110-120 and the Internet 175 using the standard Internet protocols (e.g., TCP/IP).
Referring to
In a peer-to-peer network, service discovery schemes can multicast the presence of nodes, their capabilities, and group membership. The peer-to-peer devices can establish associations and subsequent interactions based on this information.
In accordance with an aspect of the disclosure,
Referring to
In one embodiment, the supervisor device 130 may generally observe, monitor, control, or otherwise manage the various other components in the wireless communications system 100B. For example, the supervisor device 130 can communicate with an access network (e.g., access point 125) over air interface 108 and/or a direct wired connection 109 to monitor or manage attributes, activities, or other states associated with the various IoT devices 110-120 in the wireless communications system 100B. The supervisor device 130 may have a wired or wireless connection to the Internet 175 and optionally to the IoT server 170 (shown as a dotted line). The supervisor device 130 may obtain information from the Internet 175 and/or the IoT server 170 that can be used to further monitor or manage attributes, activities, or other states associated with the various IoT devices 110-120. The supervisor device 130 may be a standalone device or one of IoT devices 110-120, such as computer 120. The supervisor device 130 may be a physical device or a software application running on a physical device. The supervisor device 130 may include a user interface that can output information relating to the monitored attributes, activities, or other states associated with the IoT devices 110-120 and receive input information to control or otherwise manage the attributes, activities, or other states associated therewith. Accordingly, the supervisor device 130 may generally include various components and support various wired and wireless communication interfaces to observe, monitor, control, or otherwise manage the various components in the wireless communications system 100B.
The wireless communications system 100B shown in
For example, passive IoT devices 105 may include a coffee cup and a container of orange juice that each have an RFID tag or barcode. A cabinet IoT device and the refrigerator IoT device 116 may each have an appropriate scanner or reader that can read the RFID tag or barcode to detect when the coffee cup and/or the container of orange juice passive IoT devices 105 have been added or removed. In response to the cabinet IoT device detecting the removal of the coffee cup passive IoT device 105 and the refrigerator IoT device 116 detecting the removal of the container of orange juice passive IoT device, the supervisor device 130 may receive one or more signals that relate to the activities detected at the cabinet IoT device and the refrigerator IoT device 116. The supervisor device 130 may then infer that a user is drinking orange juice from the coffee cup and/or likes to drink orange juice from a coffee cup.
Although the foregoing describes the passive IoT devices 105 as having some form of RFID tag or barcode communication interface, the passive IoT devices 105 may include one or more devices or other physical objects that do not have such communication capabilities. For example, certain IoT devices may have appropriate scanner or reader mechanisms that can detect shapes, sizes, colors, and/or other observable features associated with the passive IoT devices 105 to identify the passive IoT devices 105. In this manner, any suitable physical object may communicate its identity and attributes and become part of the wireless communication system 100B and be observed, monitored, controlled, or otherwise managed with the supervisor device 130. Further, passive IoT devices 105 may be coupled to or otherwise made part of the wireless communications system 100A in
In accordance with another aspect of the disclosure,
The communications system 100C shown in
The IoT devices 110-118 make up an IoT group 160. An IoT device group 160 is a group of locally connected IoT devices, such as the IoT devices connected to a user's home network. Although not shown, multiple IoT device groups may be connected to and/or communicate with each other via an IoT SuperAgent 140 connected to the Internet 175. At a high level, the supervisor device 130 manages intra-group communications, while the IoT SuperAgent 140 can manage inter-group communications. Although shown as separate devices, the supervisor device 130 and the IoT SuperAgent 140 may be, or reside on, the same device (e.g., a standalone device or an IoT device, such as computer 120 in
Each IoT device 110-118 can treat the supervisor device 130 as a peer and transmit attribute/schema updates to the supervisor device 130. When an IoT device needs to communicate with another IoT device, it can request the pointer to that IoT device from the supervisor device 130 and then communicate with the target IoT device as a peer. The IoT devices 110-118 communicate with each other over a peer-to-peer communication network using a common messaging protocol (CMP). As long as two IoT devices are CMP-enabled and connected over a common communication transport, they can communicate with each other. In the protocol stack, the CMP layer 154 is below the application layer 152 and above the transport layer 156 and the physical layer 158.
In accordance with another aspect of the disclosure,
The Internet 175 is a “resource” that can be regulated using the concept of the IoT. However, the Internet 175 is just one example of a resource that is regulated, and any resource could be regulated using the concept of the IoT. Other resources that can be regulated include, but are not limited to, electricity, gas, storage, security, and the like. An IoT device may be connected to the resource and thereby regulate it, or the resource could be regulated over the Internet 175.
IoT devices can communicate with each other to regulate their use of a resource 180. For example, IoT devices such as a toaster, a computer, and a hairdryer may communicate with each other over a Bluetooth communication interface to regulate their use of electricity (the resource 180). As another example, IoT devices such as a desktop computer, a telephone, and a tablet computer may communicate over a Wi-Fi communication interface to regulate their access to the Internet 175 (the resource 180). As yet another example, IoT devices such as a stove, a clothes dryer, and a water heater may communicate over a Wi-Fi communication interface to regulate their use of gas. Alternatively, or additionally, each IoT device may be connected to an IoT server, such as IoT server 170, which has logic to regulate their use of the resource 180 based on information received from the IoT devices.
In accordance with another aspect of the disclosure,
The communications system 100E includes two IoT device groups 160A and 160B. Multiple IoT device groups may be connected to and/or communicate with each other via an IoT SuperAgent connected to the Internet 175. At a high level, an IoT SuperAgent may manage inter-group communications among IoT device groups. For example, in
As shown in
While internal components of IoT devices, such as IoT device 200A, can be embodied with different hardware configurations, a basic high-level configuration for internal hardware components is shown as platform 202 in
Accordingly, an aspect of the disclosure can include an IoT device (e.g., IoT device 200A) including the ability to perform the functions described herein. As will be appreciated by those skilled in the art, the various logic elements can be embodied in discrete elements, software modules executed on a processor (e.g., processor 208) or any combination of software and hardware to achieve the functionality disclosed herein. For example, transceiver 206, processor 208, memory 212, and I/O interface 214 may all be used cooperatively to load, store and execute the various functions disclosed herein and thus the logic to perform these functions may be distributed over various elements. Alternatively, the functionality could be incorporated into one discrete component. Therefore, the features of the IoT device 200A in
For example, the transceiver 206 may establish a wireless P2P network with one or more user devices. The processor 208 may determine whether or not the IoT device 200A is an active user device, as described below. In response to determining that the IoT device 200A is the active user device, the transceiver 206 may transmit a notification to the one or more user devices indicating that the IoT device 200A is the active user device. Alternatively, in response to determining that the IoT device 200A is not the active user device, the transceiver 206 may transmit a notification to the one or more user devices indicating that the IoT device 200A is not the active user device. If the IoT device 200A is the active user device, the transceiver 206 may receive, from a remote server, such as IoT server 170, updated application data for one or more applications installed on both the IoT device 200A and the one or more user devices, where the same user is logged in to the one or more applications on both the IoT device 200A and the one or more user devices. The transceiver 206 may then transmit the updated application data to the one or more user devices. Alternatively, if the IoT device 200A is not the active user device, the transceiver 206 may receive, from the active user device, the updated application data for the one or more applications installed on both the IoT device 200A and the active user device.
The passive IoT device 200B shown in
Although the foregoing describes the passive IoT device 200B as having some form of RF, barcode, or other I/O interface 214, the passive IoT device 200B may comprise a device or other physical object that does not have such an I/O interface 214. For example, certain IoT devices may have appropriate scanner or reader mechanisms that can detect shapes, sizes, colors, and/or other observable features associated with the passive IoT device 200B to identify the passive IoT device 200B. In this manner, any suitable physical object may communicate its identity and attributes and be observed, monitored, controlled, or otherwise managed within a controlled IoT network.

Generally, unless stated otherwise explicitly, the phrase “logic configured to” as used throughout this disclosure is intended to invoke an aspect that is at least partially implemented with hardware, and is not intended to map to software-only implementations that are independent of hardware. Also, it will be appreciated that the configured logic or “logic configured to” in the various blocks are not limited to specific logic gates or elements, but generally refer to the ability to perform the functionality described herein (either via hardware or a combination of hardware and software). Thus, the configured logics or “logic configured to” as illustrated in the various blocks are not necessarily implemented as logic gates or logic elements despite sharing the word “logic.” Other interactions or cooperation between the logic in the various blocks will become clear to one of ordinary skill in the art from a review of the aspects described below in more detail.
The various embodiments may be implemented on any of a variety of commercially available server devices, such as server 400 illustrated in
In general, user equipment (UE) such as telephones, tablet computers, laptop and desktop computers, certain vehicles, etc., can be configured to connect with each other either locally (e.g., Bluetooth, local Wi-Fi, etc.) or remotely (e.g., via cellular networks, through the Internet, etc.). Furthermore, certain UEs may also support proximity-based peer-to-peer (P2P) communication using certain wireless networking technologies (e.g., Wi-Fi, Bluetooth, Wi-Fi Direct, etc.) that enable devices to make a one-to-one connection or simultaneously connect to a group that includes several devices in order to directly communicate with one another. To that end,
A base station 510 may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or other cell types. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by devices 520 with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by devices 520 with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by devices 520 having association with the femto cell (e.g., devices 520 in a Closed Subscriber Group (CSG)). In the example shown in
Network controller 530 may couple to a set of base stations 510 and may provide coordination and control for these base stations 510. Network controller 530 may be a single network entity or a collection of network entities that can communicate with the base stations via a backhaul. The base stations may also communicate with one another, e.g., directly or indirectly via wireless or wireline backhaul. DHCP server 540 may support P2P communication, as described below. DHCP server 540 may be part of wireless network 500, external to wireless network 500, run via Internet Connection Sharing (ICS), or any suitable combination thereof. DHCP server 540 may be a separate entity (e.g., as shown in
Devices 520 may be dispersed throughout wireless network 500, and each device 520 may be stationary or mobile. A device 520 may also be referred to as a node, user equipment (UE), a station, a mobile station, a terminal, an access terminal, a subscriber unit, etc. A device 520 may be a cellular phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a smart phone, a netbook, a smartbook, a tablet, etc. A device 520 may communicate with base stations 510 in the wireless network 500 and may further communicate peer-to-peer with other devices 520. For example, as shown in
In the description herein, WAN communication may refer to communication between a device 520 and a base station 510 in wireless network 500, e.g., for a call with a remote entity such as another device 520. A WAN device is a device 520 that is interested or engaged in WAN communication. P2P communication refers to direct communication between two or more devices 520, without going through any base station 510. A P2P device is a device 520 that is interested or engaged in P2P communication, e.g., a device 520 that has traffic data for another device 520 within proximity of the P2P device. Two devices may be considered to be within proximity of one another, for example, if each device 520 can detect the other device 520. In general, a device 520 may communicate with another device 520 either directly for P2P communication or via at least one base station 510 for WAN communication.
In one embodiment, direct communication between P2P devices 520 may be organized into P2P groups. More particularly, a P2P group generally refers to a group of two or more devices 520 interested or engaged in P2P communication and a P2P link refers to a communication link for a P2P group. Furthermore, in one embodiment, a P2P group may include one device 520 designated a P2P group owner (or a P2P server) and one or more devices 520 designated P2P clients that are served by the P2P group owner. The P2P group owner may perform certain management functions such as exchanging signaling with a WAN, coordinating data transmission between the P2P group owner and P2P clients, etc. For example, as shown in
In one embodiment, P2P communication may occur only within a P2P group and may further occur only between the P2P group owner and the P2P clients associated therewith. For example, if two P2P clients within the same P2P group (e.g., devices 520g and 520i) desire to exchange information, one of the P2P clients may send the information to the P2P group owner (e.g., device 520h) and the P2P group owner may then relay transmissions to the other P2P client. In one embodiment, a particular device 520 may belong to multiple P2P groups and may behave as either a P2P group owner or a P2P client in each P2P group. Furthermore, in one embodiment, a particular P2P client may belong to only one P2P group or belong to multiple P2P group and communicate with P2P devices 520 in any of the multiple P2P groups at any particular moment. In general, communication may be facilitated via transmissions on the downlink and uplink. For WAN communication, the downlink (or forward link) refers to the communication link from base stations 510 to devices 520, and the uplink (or reverse link) refers to the communication link from devices 520 to base stations 510. For P2P communication, the P2P downlink refers to the communication link from P2P group owners to P2P clients and the P2P uplink refers to the communication link from P2P clients to P2P group owners. In certain embodiments, rather than using WAN technologies to communicate P2P, two or more devices may form smaller P2P groups and communicate P2P on a wireless local area network (WLAN) using technologies such as Wi-Fi, Bluetooth, or Wi-Fi Direct. For example, P2P communication using Wi-Fi, Bluetooth, Wi-Fi Direct, or other WLAN technologies may enable P2P communication between two or more mobile phones, game consoles, laptop computers, or other suitable communication entities.
According to one aspect of the disclosure,
In one embodiment, the distributed bus 625 may be supported by a variety of transport protocols (e.g., Bluetooth, TCP/IP, Wi-Fi, CDMA, GPRS, UMTS, etc.). For example, according to one aspect, a first device 610 may include a distributed bus node 612 and one or more local endpoints 614, wherein the distributed bus node 612 may facilitate communications between local endpoints 614 associated with the first device 610 and local endpoints 634 and 644 associated with a second device 630 and a third device 640 through the distributed bus 625 (e.g., via distributed bus nodes 632 and 642 on the second device 630 and the third device 640). As will be described in further detail below with reference to
According to one aspect of the disclosure,
In one embodiment, the bus nodes 712 and 732 may perform a suitable discovery mechanism at message sequence step 754. For example, mechanisms for discovering connections supported by Bluetooth, TCP/IP, UNIX, or the like may be used. At message sequence step 756, the local endpoint 714 on Device A 710 may request to connect to an entity, service, endpoint etc., available through bus node 712. In one embodiment, the request may include a request-and-response process between local endpoint 714 and bus node 712. At message sequence step 758, a distributed message bus may be formed to connect bus node 712 to bus node 732 and thereby establish a P2P connection between Device A 710 and Device B 730. In one embodiment, communications to form the distributed bus between the bus nodes 712 and 732 may be facilitated using a suitable proximity-based P2P protocol (e.g., the AllJoyn™ software framework designed to enable interoperability among connected products and software applications from different manufacturers to dynamically create proximal networks and facilitate proximal P2P communication). Alternatively, in one embodiment, a server (not shown) may facilitate the connection between the bus nodes 712 and 732. Furthermore, in one embodiment, a suitable authentication mechanism may be used prior to forming the connection between bus nodes 712 and 732 (e.g., SASL authentication in which a client may send an authentication command to initiate an authentication conversation). Still further, during message sequence step 758, bus nodes 712 and 732 may exchange information about other available endpoints (e.g., local endpoints 644 on Device C 640 in
In one embodiment, at message sequence step 760, bus node 712 and bus node 732 may use obtained information associated with the local endpoints 734 and 714, respectively, to create virtual endpoints that may represent the real obtained endpoints available through various bus nodes. In one embodiment, message routing on the bus node 712 may use real and virtual endpoints to deliver messages. Further, there may one local virtual endpoint for every endpoint that exists on remote devices (e.g., Device A 710). Still further, such virtual endpoints may multiplex and/or de-multiplex messages sent over the distributed bus (e.g., a connection between bus node 712 and bus node 732). In one aspect, virtual endpoints may receive messages from the local bus node 712 or 732, just like real endpoints, and may forward messages over the distributed bus. As such, the virtual endpoints may forward messages to the local bus nodes 712 and 732 from the endpoint multiplexed distributed bus connection. Furthermore, in one embodiment, virtual endpoints that correspond to virtual endpoints on a remote device may be reconnected at any time to accommodate desired topologies of specific transport types. In such an aspect, UNIX based virtual endpoints may be considered local and as such may not be considered candidates for reconnection. Further, TCP-based virtual endpoints may be optimized for one hop routing (e.g., each bus node 712 and 732 may be directly connected to each other). Still further, Bluetooth-based virtual endpoints may be optimized for a single pico-net (e.g., one master and n slaves) in which the Bluetooth-based master may be the same bus node as a local master node.
At message sequence step 762, the bus node 712 and the bus node 732 may exchange bus state information to merge bus instances and enable communication over the distributed bus. For example, in one embodiment, the bus state information may include a well-known to unique endpoint name mapping, matching rules, routing group, or other suitable information. In one embodiment, the state information may be communicated between the bus node 712 and the bus node 732 instances using an interface with local endpoints 714 and 734 communicating with using a distributed bus based local name. In another aspect, bus node 712 and bus node 732 may each may maintain a local bus controller responsible for providing feedback to the distributed bus, wherein the bus controller may translate global methods, arguments, signals, and other information into the standards associated with the distributed bus. At message sequence step 764, the bus node 712 and the bus node 732 may communicate (e.g., broadcast) signals to inform the respective local endpoints 714 and 734 about any changes introduced during bus node connections, such as described above. In one embodiment, new and/or removed global and/or translated names may be indicated with name owner changed signals. Furthermore, global names that may be lost locally (e.g., due to name collisions) may be indicated with name lost signals. Still further, global names that are transferred due to name collisions may be indicated with name owner changed signals and unique names that disappear if and/or when the bus node 712 and the bus node 732 become disconnected may be indicated with name owner changed signals.
As used above, well-known names may be used to uniquely describe local endpoints 714 and 734. In one embodiment, when communications occur between Device A 710 and Device B 730, different well-known name types may be used. For example, a device local name may exist only on the bus node 712 associated with Device A 710 to which the bus node 712 directly attaches. In another example, a global name may exist on all known bus nodes 712 and 732, where only one owner of the name may exist on all bus segments. In other words, when the bus node 712 and bus node 732 are joined and any collisions occur, one of the owners may lose the global name. In still another example, a translated name may be used when a client is connected to other bus nodes associated with a virtual bus. In such an aspect, the translated name may include an appended end (e.g., a local endpoint 714 with well-known name “org.foo” connected to the distributed bus with Globally Unique Identifier “1234” may be seen as “G1234.org.foo”).
At message sequence step 766, the bus node 712 and the bus node 732 may communicate (e.g., broadcast) signals to inform other bus nodes of changes to endpoint bus topologies. Thereafter, traffic from local endpoint 714 may move through virtual endpoints to reach intended local endpoint 734 on Device B 730. Further, in operation, communications between local endpoint 714 and local endpoint 734 may use routing groups. In one aspect, routing groups may enable endpoints to receive signals, method calls, or other suitable information from a subset of endpoints. As such, a routing name may be determined by an application connected to a bus node 712 or 732. For example, a P2P application may use a unique, well-known routing group name built into the application. Further, bus nodes 712 and 732 may support registering and/or de-registering of local endpoints 714 and 734 with routing groups. In one embodiment, routing groups may have no persistence beyond a current bus instance. In another aspect, applications may register for their preferred routing groups each time they connect to the distributed bus. Still further, groups may be open (e.g., any endpoint can join) or closed (e.g., only the creator of the group can modify the group). Yet further, a bus node 712 or 732 may send signals to notify other remote bus nodes or additions, removals, or other changes to routing group endpoints. In such embodiments, the bus node 712 or 732 may send a routing group change signal to other group members whenever a member is added and/or removed from the group. Further, the bus node 712 or 732 may send a routing group change signal to endpoints that disconnect from the distributed bus without first removing themselves from the routing group.
Many users have multiple mobile devices and may have the same application(s) installed on each of them. For example, a user may have a smartphone, a laptop computer, and a tablet computer, and may install the same social networking, micro-blogging, and/or email applications on each device. Typically, an application on a device synchronizes data for that application independently of any synchronization for that application occurring at the other devices. For example, when new data is available for the social networking application, the user's smartphone, laptop computer, and tablet computer will each download the same data.
This duplication of synchronizations presents several issues. For example, every time a device needs to download new data or poll for new data, it may have to exit the idle mode, set up a common control channel, request a dedicated channel, and then enter a dedicated state. This wastes power, which is an important consideration for battery-powered devices. It is also a waste of bandwidth to download the same data on each device.
Accordingly, the various aspects of the disclosure enable collaboration between a user's various devices to intelligently synchronize data and minimize the bandwidth and power usage of the devices.
An exemplary aspect of the disclosure will be discussed with reference to
The user devices 810-840 may each be running one or more of the same applications, such as the same social networking application and/or the same micro-blogging application. The user may be logged in to each of these applications with the same user credentials, for example, the same username and password. Such applications are referred to herein as “common” applications. The user device 810-840 can determine which applications they have in common by communicating with each other over the P2P interface.
After establishing the P2P network 800, the user devices 810-840 communicate with each other to choose one device to be an “active device” based on certain criteria. For example, a device that detects current user activity, that is not in sleep mode, that has at least one application running, or whose display is on may be chosen as the “active device.” Note that in sleep mode, a device may not be running any applications, or they may be running in a background mode, and the display may be off. As such, determining that a device is in sleep mode may include determining that it does not have any applications running and/or that the display is off.
If there are no active devices, or if there is more than one active device, the device with the highest battery charge available or that is connected to a power supply may be chosen as the active device. If the active device later fails to meet the active device criteria, this status change is communicated to the other devices in the P2P network 800 and a new active device is chosen using the active device criteria. For purposes of illustration only, in the example of
At 950, if there is current user activity, or if the device is not in sleep mode, or if the device is currently charging, the device determines whether or not its battery level is greater than a threshold. If it is, then at 960, the device determines that it is the “active device” and broadcasts this status to the other devices in the P2P network 800. If, at 950, the device determines that its battery is not charging, then the flow proceeds to 970. Where a device is not battery operated, the decisions at 940 and 950 can be skipped and the flow can proceed to 960.
At 970, if there is no current user activity, and if the device is in sleep mode, and if the device is not currently charging, the device determines whether or not it is the current “active device.” If it is not, then the flow returns to 910, and the device waits for the next periodic polling. If it is, however, then at 980, the device sets its status to “inactive device” and broadcasts this status to the other devices in the P2P network 800.
Referring back to
When there is new data available for any of the common applications, the active device (e.g., smartphone 810) downloads the new data and “pushes” it to the remaining devices (e.g., devices 820-840) through the P2P interface. The other user devices 820-840 synchronize the new data directly from the active device 810, rather than the corresponding remote server. The active device 810 can use standard multicast protocols over the P2P interface to synchronize the new data with the other user devices 820-840.
In this way, the user devices 820-840 can reduce their power consumption in at least two ways. First, the devices 820-840 wake up only when there is new data for a common application. They do not have to wake up periodically according to the synchronization settings of each of the common applications. Second, the user devices 810-840 can use a multicast protocol to synchronize the new data. This is more power efficient than each device 810-840 synchronizing with the network and downloading the new data independently. Additionally, the various aspects of the disclosure reduce unnecessary usage of network bandwidth, since only one device, the active device 810, synchronizes the data for the common applications.
At 1010, the user device establishes a wireless P2P network with one or more other user devices.
At 1020, the user device determines that it and the one or more other user devices each have one or more applications in common. That is, the user device and the one or more other user devices each have the same one or more applications installed and the same user is logged in to each application using the same logon credentials for those applications.
At 1030, the user device determines that it is not an active device. The determining may include determining that there is no current user activity on the user device, that there is not at least one application running on the user device, that the user device is in a sleep mode, and that a display of the user device is powered off. Alternatively, determining that the user device is not the active user device may include determining that there is no current user activity on the user device, that the user device is in a sleep mode, and that the user device is not currently charging, as in 920-940 of
At 1040, in response to determining that the user device is not the active device, the user device transmits a notification to the one or more other user devices indicating that the user device is not the active user device, as at 980 of
At 1050, the user device receives a notification that another user device is the active device. As discussed above with reference to
At 1060, the user device is barred from polling a remote server for updated application data for the one or more common applications. Likewise, the user device is barred from polling the active device for updated application data for the one or more common applications.
At 1070, the user device receives, from the active user device, updated application data for the one or more common applications. The user device may receive the updated application data from the active device over the wireless P2P network. The active user device may receive the updated application data by synchronizing with the remote server.
At 1110, the user device establishes a wireless P2P network with one or more other user devices.
At 1120, the user device determines that it and the one or more other user devices each have one or more applications in common. That is, the user device and the one or more other user devices each have the same one or more applications installed and the same user is logged in to each application using the same logon credentials for the same applications.
At 1130, the user device determines that it is an active device. The determining may include determining that there is current user activity on the user device, that there is at least one application running on the user device, that the user device is not in sleep mode, or that a display of the user device is powered on. The determining may also include determining that the user device has a higher battery level than another user device that detects current user activity, that has at least one application running, that is not in sleep mode, or that has a display that is powered on. The determining may also include determining that the user device is connected to a power supply.
In another aspect, determining that the user device is the active device may include determining that there is current user activity on the user device, that the user device is not in a sleep mode, or that the user device is currently charging, as at 920-940 of
At 1140, the user device notifies the one or more other user devices that it is the active device. The one or more inactive devices will then be barred from polling a remote server for updated application data for the one or more common applications.
At 1150, the user device receives, from a remote server, updated application data for the one or more common applications.
At 1160, in response to receiving the updated application data, the user device transmits (pushes) the updated application data to the one or more other devices. The transmitting may be performed over the P2P network. The transmitting may include transmitting the updated application data to the one or more other devices via a multicast interface.
