1. Field of the Invention
The present invention is directed to a wireless Internet service provider, mobile network operator or any such wireless operators for private or public use. Specifically, the invention is adapted to facilitate the recovering of a data communication or data call across different wireless technology platforms or across different private and public wireless networks, provided the user is an authorised user of such different wireless technology platforms or such different wireless-service providers or -network operators such that loss of data on one wireless-platform or -provider and a data reconnection on a same or different wireless-platform or -provider allows recovery of the original data call and thus a continuation of the same original data call.
2. Technical Background
Current wireless systems and methods do not provide for a way to recover and continue a wireless data communication or wireless data call across different radio technologies. The prior art solutions only apply when a wireless data communication or wireless data call remains within the same radio technology. The most commonly known definitions (mostly defined as standards) of these partial solutions in the prior art are known as different names, such as seamless hand-over, non-seamless hand-over, mid-call hand-over and so forth, however none of these standards and non-standard partial solutions in the prior art resolves the main issue for wireless end-user devices; which is to recover and continue a data call when changing throughout different radio technology platforms available and authorised for data use on such end-users wireless devices.
As a matter of illustration to understand the main issue this invention resolves and which has not been fixed by any of the prior arts; say a wireless device is capable of handling data communications or data calls through the following radio data technologies: WiFi (wireless fidelity) through a private- or public-WLAN (wireless local area network), GSM/UMTS (Global System for Mobile Communications/Universal Mobile Telecommunications Service) and that same user's wireless device is an authorised user of such previously mentioned wireless systems that provide radio coverage for such systems (i.e. WiFi and GSM/UMTS) then in the prior art if a wireless device user initiated a data call through WiFi and whilst it's on-going on that 1rd radio technology platform WiFi to a 3rd party and that data call is lost and the wireless device reconnects to a 2nd radio technology platform GSM/UMTS, then such wireless device original data call is terminated permanently in the prior art.
The same would happen, namely a data call from a wireless device as described previously would be terminated after the initial data call on a 1st radio technology platform looses data connection or radio coverage and such same data call would not recover and continue when the same wireless device reconnects to a 2nd different to the 1st radio technology platform in any combination; when from WiFi to GSM/UMTS or from GSM/UMTS to WiFi or between any such other wireless technology platforms or also referred herein as radio technology platforms.
Recently, fixed line and mobile network operators and service providers in particular have begun to offer on-line (internet) services allowing individuals to make wireless text-, voice- and video-data calls over a variety of standards or proprietary protocols competing head-on with the traditional analogue and digital data calls from traditional network operators, yet none provide a solution that would allow a wireless device end-user to restore an original data call on one radio technology to continue that same data call when the wireless device reconnects on another radio technology, provided the time between loosing data connection from the 1st radio technology and re-connecting to the same or to a 2nd radio technology is within a reasonable timeframe acceptable to end-users (i.e. in the region of seconds or tenths of seconds not minutes).
Attempts have been made to ease the way to wireless end-users always focused on some form of hand-over defined in standards and some non standard; however none of the prior art allows any reliable solution across different radio technologies available in end-users wireless devices to which they are authorised users to, other then the partial solution described above, which in itself does not provide a solution to the issue described herein before.
