Abstract:
1. A method in a data connectivity management component for use in establishing, via a wireless communication network, a data session for packet data communications for a data application of a mobile communication device, the mobile device including the data connectivity management component and a radio component separate from the data connectivity management component, the method comprising the acts of: sending, from the data connectivity management component to the radio component, a data connection request for transmission from the radio component to the wireless network in attempt to establish the data session for the mobile device, the transmission of the data connection request being retried a plurality of times by the radio component independently if the data session has not been established in response to the data connection request; setting, by the data connectivity management component, a delay timer to an initial value and running the delay timer; if, prior to expiration of the delay timer set to the initial value, the data session is established in response to transmitting the data connection request or the corresponding retries, then communicating packet data via the wireless network for the packet data communications of the data session; if, upon expiration of the delay timer set to the initial value, the data session has not been established in response to transmitting the data connection request and corresponding retries, then: if, prior to expiration of the delay timer set to the subsequent initial value, the data session is established in response to transmitting the subsequent data connection request or corresponding retries, then communicating packet data via the wireless network for the packet data communications of the data session; and if, upon expiration of the delay timer set to the subsequent initial value, the data session has not been established in response to transmitting the subsequent data connection request and corresponding retries, then:
