Abstract

A host service queues one or more data messages for delivery to a wireless mobile device, and attempts to authenticate whether a service session with the device is active. A session includes a saved login credential over a predetermined time period, where the credential was previously received and saved from a previous login. When the session is active, the host service sends the data message to the device via a wireless network. When the session is inactive, the host service sends a notification message to the router system over a previously-established connection. The notification message is subsequently forwarded by the router system to the device in the wireless network. After sending the notification message, the host service receives a new login credential from the device for activating a new service session, authenticates the new login credential, and activates the new service session for data message delivery.

A method in a host service for use in communicating data messages between the host service and a wireless mobile device configured to operate in a wireless network, the method comprising:

establishing a connection with a router system;
queuing one or more data messages for delivery to the wireless mobile device;
attempting to authenticate whether a service session with the wireless mobile device is active, the service session including a saved login credential of the wireless mobile device over a predetermined time period, the saved login credential being previously received and saved at the host service from a previous login of the wireless mobile device at the host service for activating the service session;
when the service session is active, sending the one or more data messages to the wireless mobile device via the wireless network;
when the service session is inactive:
sending a notification message to the router system over the connection, the notification message being subsequently forwarded by the router system to the wireless mobile device in the wireless network;
after sending the notification message, receiving a new login credential from the wireless mobile device for activating a new service session;
