A communication system, mobile device therefor and methods of storing pages on a mobile device

Abstract

A mobile telephone (1) is provided with an additional plug-in on its SIM card (2a), in the form of a domestic browser (12) with a domestic site (14). When a mobile user wants to access a page, such as an internet page on his telephone, the domestic browser searches a first file in a domestic site (14a) for the page identifier to see if the page is immediately accessible. If it is, then it retrieves the data from a second file in the domestic site another memory (14b) and' executes it for display. On the other hand, if the page identifier cannot be located in the domestic site (14a), the domestic browser (12) simply returns a negative result, at which point the SIM browser (10) on the SIM card (2a) has the page request transmitted to have the page retrieved from the Internet. The user of the mobile telephone (1) does not determine whether any page is to be saved in the domestic site (14), instead it is determined by the mobile operator or the page writer, by use of codes written into the WML page contents. The operator can also transmit push pages onto the mobile telephone (1) and have them saved, updated or deleted in the domestic site (14) without any user intervention.

Description

technical field [0001] The invention relates to a communication system and its mobile equipment, and a method for storing pages on the mobile equipment. In particular it relates to aspects that can be considered within the scope of a browser and download information into mobile devices such as mobile phones, personal digital assistants (PDAs), portable computers, and the like. Background technique [0002] Mobile phones can use existing technologies for data communication. Currently known technologies include short message (SM) and GPRS, and 3G technology is expected to be fully utilized in the next few years. The actual data communication can be done using the Wireless Application Protocol (WAP), which is usually embedded in the mobile phone device, or via a browser, which is usually embedded in the Subscriber Identity Module (SIM) . [0003] exist figure 1 A typical browsing operation on a mobile device is schematically represented in . The phone 1 includes a SIM card...

AI Technical Summary

Problems solved by technology

First, it is slow; each page, group of pages, or application must be downloaded individually from an Internet server 5

Each such request then also has to compete with other requests made by other people retrieving new pages etc. at the same time, and the more such requests there are at any one time, the slower the system becomes

Additionally, there is the issue of having to use the SIM Application Tool (SAT) when developing all services for use on a SIM card or equivalent on a mobile device
