DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0006] Embodiments are directed to systems and methods for device connectivity management.

[0007] Referring to Figure 1, a block diagram of a system for device connectivity management is disclosed according to one embodiment. System 100 may include a plurality of clients (110 1 , 110 2 , ... 110 n ), a plurality of agents (115 1 , 115 2 , ... 115 n ), cloud 120, broker 122 hosted in cloud 122, and central monitoring service 124 also hosted in cloud 120. Clients 110 1 , 110 2 , ... 110 n may support one or more communication channels, including Ethernet, WiFi, GSM radio, Bluetooth, etc., for communicating with broker 122.

[0008] In one embodiment, broker 122 and / or central monitoring service 124 may be hosted one or more datacenter (not shown).

[0009] In one embodiment, each client 110 1 , 110 2 , ... 110 n may include an agent 115 1 , 115 2 , ... 115 n that may execute a service that may check in with broker 122 over each supported communication channel. In one embodiment, clients 110 1 , 110 2 , ... 110 n may check in at regular intervals, at irregular intervals, on demand, or as otherwise necessary and / or desired.

[0010] In one embodiment, browser 122 may implement the MQTT messaging protocol, and clients 110 1 , 110 2 , ... 110 n may subscribe to receiving messages from broker 122. In one embodiment, each client 110 1 , 110 2 , ... 110 n may subscribe to broker 122 over each of its supported communication channels. For example, if client 115 supports Ethernet, WiFi, and GSM, client 115 may send a separate subscription message to broker 122.

[0011] Although the MQTT protocol is discussed herein, it should be recognized that other protocols may be used as is necessary and / or desired.

[0012] In one embodiment, each client 110 1 , 110 2 , ... 110 n may send a "last will and testament," or LWT, message to broker 122. The LWT message is distributed to all other subscribed clients if the sending client does not respond to a "keep alive" message from broker 122.

[0013] In one embodiment, broker 122 may communicate the keep alive message to each client 110 1 , 110 2 , ... 110 n over each of the client's subscribed communication channels. For example, if client 115 supports Ethernet, WiFi, and GSM, broker 122 sends a keep alive message to client 115 over each of these communication channels.

[0014] (0033) Each client 110 1 , 110 2 , ... 110 n may respond to the keep alive message within a certain period. If one of the clients 110 1 , 110 2 , ... 110 n does not respond over one of its subscribed communication channels, broker 122 may determine that the client or the communication channel is offline.

[0015] In one embodiment, central monitoring service 124 may also subscribe to broker 122 and may monitor any messages published by broker 122. In one embodiment,

[0016] In one embodiment, central monitoring service 124 may receive maintenance update information (e.g., WiFi maintenance), service outage information (e.g., GSM outage information for a certain region), etc. Based on this information and / or messages published by broker 122, central monitoring service 124 may provide status updates, instructions, commands, etc. to clients 110 1 , 110 2 , ... 110 n and / or agents 115 1 , 115 2 , ... 115 n through any suitable communication network, including email, SMS, etc.

[0017] In one embodiment, agents 115 1 , 115 2 , ... 115 n may take an appropriate action in response to not receiving a keep alive message from broker 122, such as changing the active communication channel. Agents 115 1 , 115 2 , ... 115 n . may also execute commands or instructions provided by central monitoring service 124.

[0018] Referring to Figure 2, a schematic diagram of an agent is provided according to one embodiment. Agent 115 may support a plurality of connections (e.g., Wi-Fi, GSM, Ethernet, etc.). Agent 115 may include local monitoring service (LMS) 210 that subscribes to, and receives event information, from broker 122 in cloud 120.

[0019] Although LMS 210 is illustrated as being part of agent 115, it should be recognized that LMS 210 may be part of a separate entity (not shown) that is executed by client 110. Other configurations may be used as is necessary and / or desired.

[0020] Agent 115 may manage client 110's connections to broker 122 and may run LMS 210 to act on events that are of interest in managing connectivity. For example, the events received from broker 122 may relay information about connection interfaces, or about configuration, for example, "connective 1 down", or "switch connection 2 to primary / preferred path".

[0021] Referring to Figure 3, a method for device connectivity management is disclosed according to one embodiment. In step 305, a client, such as a point of sale device, may come online. For example, the client may be powered up.

[0022] In step 310, the client may subscribe to a broker over each supported communication channel. For example, the client may subscribe to broker over ethernet, WiFi, GSM, Bluetooth, or any other suitable communication channel.

[0023] In one embodiment, the client may communicate a LWT message using the MQTT protocol. Other messaging protocols may be used as is necessary and / or desired.

[0024] In step 315, the broker may send a keep alive message to each client over each subscribed communication channel. In one embodiment, the keep alive message may be sent periodically, aperiodically, on demand, or as otherwise necessary and / or desired.

[0025] Each client may respond to each keep alive message that it receives over each subscribed communication channel.

[0026] In step 320, the broker may determine whether it received responses to the keep alive messages on the subscribed communication channels from each client. If a response is not received on a communication channel, in step 325, the broker may publish a status of the non-responding client(s) and / or communication channel(s) to the responding clients.

[0027] In step 330, an agent on the client with a non-responsive communication channel may take an action in response to publication. For example, the client may select a communication channel to use other than the non-responsive communication channel.

[0028] In another embodiment, a client may not receive a keep alive message on its GSM communication channel, but may receive a keep alive message on its WiFi communication channel. This may trigger the client to switch or reprioritize the communication channels.

[0029] (0048) In step 335, agents on other clients may evaluate the publication and may take a suitable action, such as changing communication channels, reprioritizing communication channels, etc. For example, if the agent determines that, in view of the publication, the ethernet communication channel may be compromised, it may switch to the WiFi communication channel.

[0030] In step 340, the broker may wait for the non-responding client to subscribe again over the non-responsive communication channel, indicating that the communication channel in question has been restored. If, in step 345, it has, the process may repeat.

[0031] Referring to Figure 4, a method for device connectivity management is disclosed according to one embodiment. In step 405, a client, such as a point of sale device, may come online. For example, the client may be powered up.

[0032] In step 410, the client may subscribe to a broker over each supported communication channel. For example, the client may communicate over ethernet, WiFi, GSM, Bluetooth, or any other suitable communication channel.

[0033] In one embodiment, the client may communicate a LWT message using the MQTT protocol. Other messaging protocols may be used as is necessary and / or desired.

[0034] In step 415, the broker may send a keep alive message to each client over each subscribed communication channel. In one embodiment, the keep alive message may be sent periodically, aperiodically, on demand, or as otherwise necessary and / or desired.

[0035] Each client may respond to each keep alive message that it receives over each subscribed communication channel.

[0036] In step 420, the broker may determine whether it received responses to the keep alive messages on the subscribed communication channels. For example, a client may not receive a keep alive message on its GSM communication channel, but may receive a keep alive message on its WiFi communication channel.

[0037] If a response is not received on a communication channel, in step 425, the broker may publish a status of the non-responding client(s) and / or communication channel(s) to the responding clients.

[0038] In step 430, a central monitoring service, which may also be a subscriber to the broker, may receive the publication and may determine what action, if any to take. For example, the central monitoring service may instruct the non-responsive client to use a communication channel other than the one that is nonresponsive. As another example, the central monitoring service may instruct other clients to use other communication channels. Other actions may be identified as is necessary and / or desired.

[0039] In one embodiment, the central monitoring service may receive other information, such as maintenance information, service outage information, and may use this information and / or the status messages to determine an action to instruct the clients to take. In one embodiment, the information may come from a network provider, from a maintenance provider, etc.

[0040] In another embodiment, the central monitoring service may receive updated channel priority policies, and may communicate those policies to the clients.

[0041] In step 435, the central monitoring service may communicate the action to the client(s). In one embodiment, the communication may occur over any suitable communication channel, including a separate communication channel, such as SMS, email, etc.

[0042] In step 440, the client(s) may take action in response to the communication from the central monitoring service.

[0043] In step 445, the broker may wait for the non-responding client to subscribe again over the non-responsive communication channel. If, in step 450, it has, the process may repeat.

[0044] Referring to Figure 5, a method for device connectivity management is disclosed according to one embodiment.

[0045] In step 505, a client, such as a point of sale device, may come online. For example, the client may be powered up.

[0046] In step 510, the client may subscribe to a broker over each supported communication channel. For example, the client may communicate over ethernet, WiFi, GSM, Bluetooth, or any other suitable communication channel.

[0047] In one embodiment, the LMS on the client may subscribe to the broker.

[0048] In one embodiment, the client may communicate a LWT message using the MQTT protocol. Other messaging protocols may be used as is necessary and / or desired.

[0049] In step 515, the broker may detect an event from the broker. In one embodiment, the event may be an event that affects communications, such as a GSM jam or cellular outage event, etc. In another embodiment, the event may be a maintenance event (e.g., WiFi maintenance), a security event (e.g., security keys compromised, etc.). Any other suitable events may be included as is necessary and / or desired.

[0050] In step 520, the broker and / or the central management service may communicate the event and / or instructions to the LMS of affected subscribed clients. For example, the central management service may communicate the event type, one or more action to take (e.g., change connection type, such as change from GSM to WiFi), execute maintenance (e.g. switch traffic to different connection type and publish complete message when maintenance is completed), etc.

[0051] In step 525, the LMS for the clients may take the appropriate action. For example, an agent executed by the client may interpret the event and may take an appropriate action. In another embodiment, the client may execute the action provided by the central management service.

[0052] In one embodiment, machine learning may be used to improve connectivity. For example, data, such as connection times and other telemetry, may be harvested and events may be detected based on past events. In one embodiment, machine learning may be used for the client and / or central management system may use statistical techniques to develop thresholds, rules, etc.
