Patent ID: 8099082

Claim:
A method in a host service for controlling service sessions between the host service and a wireless mobile device which is operable in a wireless network, the method comprising the steps of: queuing, over a predetermined time interval, one or more electronic mail (e-mail) messages received at an e-mail server for delivery to the wireless mobile device; detecting, at the host service, a trigger in response to an expiration of the predetermined time interval; in response to the detecting of the trigger and when the one or more e-mail messages are queued: attempting to authenticate, at the host service, at least one previously received login credential of the wireless mobile device with respect to a predetermined authentication period, the at least one previously received login credential being previously received at the host service from a previous login of the wireless mobile device at the host service for activating a service session for e-mail message delivery; when the host service identifies that the predetermined authentication period associated with the at least one previously received login credential has not expired, the service session for e-mail message delivery being active; otherwise, when the host service identifies that the predetermined authentication period associated with the at least one previously received login credential has expired, which indicates that the service session for e-mail message delivery is inactive, then: requesting, via the wireless network, at least one new login credential of the wireless mobile device; receiving, via the wireless network, the at least one new login credential from the wireless mobile device; authenticating, at the host service, the at least one new login credential; activating the service session for e-mail message delivery based on the authenticating of the at least one new login credential; and when the service session for e-mail message delivery is active: causing the one or more e-mail messages to be sent in a batch mode, from the host service via the wireless network, to the wireless mobile device.
