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. |
