Common to Android and iOS
Only CT policies can be applied to smart devices (agents).
Data is transferred periodically between smart devices (agents) and the Management Server. Therefore, it is advisable to subscribe to a fixed price packet communication plan. Refer to "Timing of communication between a smart device (agent) and the Management Server" for details on communication timing and transferred data.
Smart devices (agents) do not support DTKCTEntry.csv (automatic distribution file during CT registration) for automatic distribution during CT registration. All smart devices (agents) are placed directly under the root during registration.
The table below lists the timing of communication between a smart device (agent) and the Management Server. Even if you update the policy for a smart device (agent) and click Update Immediately on Management Console, the updated policy will not be applied to the smart device (agent) until the time indicated below.
Timing | Description of communication | |
|---|---|---|
Smart device (agent) to Management Server | Management Server to smart device (agent) | |
Android | ||
When the smart device (agent) is started (*3) | Device information Accumulated operation logs Accumulated prohibition logs | Policy information |
Every 8 hours (*1) | Accumulated operation logs (*2) | - |
Every hour (*1) | Accumulated prohibition logs (*2) Remote control request confirmation (*4) | - |
Once per day at a set time (12:00 to 13:00) | Device information (*2) | Policy information |
When Sync now is clicked on the smart device (agent) | Device information Accumulated operation logs Accumulated prohibition logs Remote control request confirmation (*4) | Policy information |
iOS | ||
When the relay server is started | Device information | - |
Every 24 hours after the relay server is started | Device information | - |
*1: The smart device (agent) startup time is used as the reference point.
*2: If the communication status or other reason prevents data transfer, retry is performed when communication is enabled. In addition, communication is attempted as soon as Wi-Fi is enabled. If both the retry and the attempt fail, data will be transferred at the timing described below.
*3: This timing applies if Synchronize when starting up is selected in the smart device (agent) settings window (the smart device (agent) starts when the smart device starts up)
*4: A remote control request confirmation is a communication that periodically asks if a remote control request has been made to smart device (agent).
If a remote control request has been made, the smart device (agent) sends the device information and also sends a communication to obtain policy information.
Android
The user can use a standard application (for example, settings) that changes the smart device environment to uninstall a smart device (agent), as follows:
Set a client management password and ensure that Select device administrators > Desktop Keeper Client cannot be cleared.
Under the following condition, the user can forcibly stop the smart device (agent) or delete data:
Select device administrators > Desktop Keeper Client is cleared on the smart device
Follow the procedure below:
Configure operation to prevent smart device (agent) data from being deleted and the smart device (agent) from being forcibly stopped.
Set a client management password and ensure that Select device administrators > Desktop Keeper Client cannot be cleared (supported in Android 4.0 and later).
Operation in the multi-user environment of Android 4.2 or later is not supported.
Note
The Smart Device Relay Server and the smart device (agent) communicate periodically.
Therefore, follow the procedure below so that connection is not closed during sleep when communication happens via Wi-Fi:
Tap Settings > Wireless & networks > Wi-Fi settings > Advanced > Wi-Fi sleep policy, and select Never.
The setting may be found in a different location depending on the model. Refer to the manual for your model for details.
This setting may affect battery time.
If you do not configure this setting, the smart device (agent) may not be able to receive any remote control requests.
You do not need to configure this setting for communication with Smart Device Relay Server via a 3G line.
iOS
The wipe information following a failure of the prescribed number of retries to clear the screen lock on a smart device (agent) (iOS) is not sent to Smart Device Relay Server. Therefore, you cannot confirm a wipe on Management Console.
If Content Ratings is set for an iOS device, region settings different from Ratings region in the iOS device may not take effect.
Configure the setting to suit the Ratings region setting in the iOS device.
