Abstract: A method includes steps, performed by a wireless device for accessing a wireless network through network base stations. The steps include selecting a reverse link cost metric from a list of reverse link cost metrics. A reverse link cost is determined according to the selected reverse link cost metric. A plurality of base stations are partitioned into a plurality of candidate base stations and a plurality of excluded base stations. The plurality of base stations are substituted with the candidate base stations, thereby reducing the cardinality of the plurality of base stations by the cardinality of the plurality of excluded base stations. A candidate base station is selected from a plurality of the base stations. A probe signal is sent at the reverse link cost to the candidate base station. A response from the candidate base station is waited for within a timeout period.

Abstract: A system and method for establishing and maintaining an “always-on” data connection to a wireless network through the use of a back off timer and a service check timer is disclosed. The back off timer is initialized to a determined value when a connection is not established. When the timer expires, a connection attempt is made. As further connection attempts are made, the back off timer is set to ever-increasing values. When the data connection is established, the service check timer is initialized. The data connection status is determined at the expiry of the service check timer. When, at the expiry of the service check timer, the data connection is determined to be lost, the connection method is employed.

Abstract: According to the embodiments of the techniques of this application, a wireless data device or other data node sends solicitation messages periodically to a wireless gateway, such as a PDSN, when there is no data traffic between the wireless data device and a wireless data network. Each solicitation message resets the simple IP inactivity timer on the wireless gateway. When multiple wireless data devices send solicitation messages, the interval between subsequent transmissions of solicitation messages is randomised to reduce the probability of collision with the solicitations from other devices on the same wireless link. The solicitation timer, for instance, may be based on the simple IP inactivity timer setting on the wireless network, and the number of wireless data devices that the wireless data network serves. Expiration of the solicitation timer at the wireless data device or other data node causes the next solicitation message to be sent from or on behalf of the wireless data device.

The calibration value controls the power amplifier gain characteristics in real time.
