Monitoring mobile device

An apparatus, comprising at least one processor;

• and at least one memory including computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus to perform:
• determine, by an online server functionality, a mobile device to be monitored based on at least partially an Internet Protocol, IP, address of the mobile device;
• execute, by the online server functionality, an IP-based two-way communications protocol with the mobile device by transmitting one or more request messages;
• determine, by the online server functionality, one or more lost responses from the mobile device to the one or more request messages;
• and
• cause, by the online server functionality, to generate a request to another entity for triggering the another entity to select one or more recovery methods for the mobile device.

An apparatus comprising at least one processor;

• and at least one memory including computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus to:
• receive, by a management function, a request to select one or more recovery methods for a mobile device addressable in a communications network by an Internet Protocol, IP, address;
• apply, by the management function, at least one recovery method to the mobile device;
• and
• after the recovery method has been applied, in response to determining a recovery of the mobile device, transmit, by the management function, information indicating the recovery of the mobile device to the online server functionality.

An apparatus comprising at least one processor;

• and at least one memory including computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus to perform:
• receive by a mobile device, from a network a release or detach indication triggered based at least in part on a trigger message caused by at least one lost response by a server;
• cause by the mobile device, a release or detach operation with the mobile communications network;
• establish a connection with the network;
• cause to receive, by the mobile device, a request from the server through the connection with the network;
• cause a reply to the request by the mobile device in the connection with the network to the server.
