Mobile device 100 may send and receive communication signals over network 200 after required network registration or activation procedures have been completed. Network access is associated with a subscriber or user of a mobile device 100. To identify a subscriber, mobile device 100 requires a Subscriber Identity Module or “SIM” card 126 to be inserted in a SIM interface 128 in order to communicate with a network. SIM 126 is one type of a conventional “smart card” used to identify a subscriber of mobile device 100 and to personalize the mobile device 100, among other things. Without SIM 126, mobile device 100 is not fully operational for communication with network 200.
The particular design of communication subsystem 104 is dependent upon the network 200 in which mobile device 100 is intended to operate, thus it should be understood that the design illustrated in FIG. 2 serves only as one example. Signals received by antenna 154 through network 200 are input to receiver 150, which may perform such common receiver functions as signal amplification, frequency down conversion, filtering, channel selection, and analog-to-digital (A/D) conversion. ND conversion of a received signal allows more complex communication functions such as demodulation and decoding to be performed in DSP 160. In a similar manner, signals to be transmitted are processed, including modulation and encoding, by DSP 160. These DSP-processed signals are input to transmitter 152 for digital-to-analog (D/A) conversion, frequency up conversion, filtering, amplification and transmission over network 200 via antenna 156. DSP 160 not only processes communication signals, but also provides for receiver and transmitter control. For example, the gains applied to communication signals in receiver 150 and transmitter 152 may be adaptively controlled through automatic gain control algorithms implemented in DSP 160.
For embodiments of mobile device 100 described hereinafter, the mobile device 100 is equipped and configured for communication over a cellular connection via communication subsystem 104 and with a wireless local area network (WLAN) using a communication form commonly termed “Wi-Fi”. Such Wi-Fi connections may employ a suitable WLAN-compatible communication technology, of which unlicensed mobile access (UMA) technology is one example. UMA technology provides access to GSM and GPRS mobile services over unlicensed spectrum technologies, including Bluetooth™ and 802.11 wireless connections. UMA enables cellular network subscribers to roam and hand over between cellular networks and public and private wireless networks using dual-mode mobile handsets.
Optionally, mobile device 100 may also be configured for communication with local wireless devices, such as Bluetooth™ enabled devices and may be configured for communication in a global positioning system (GPS) context.
User interface module 420 also facilitates the receipt of user input in relation to the images displayed on display 110. For example, selection of an icon, such as a “manage connections” icon, may be performed by using user interface module 420 to highlight an icon or drop-down menu item and then actuating an auxiliary I/O device 112 to “click” on the icon. However, display of a particular icon combinations in a banner area of display 110, as described below, is performed by user interface module 420 without requiring any specific input from the user.
Referring now to FIG. 5, there is shown a method 500 of displaying icon combinations representative of available wireless transmission modes, including cellular and WLAN connections. Method 500 begins at step 510, in which user interface module 420 (or a manage connections application interfacing with user interface module 420) determines the connection status of the cellular and WLAN connections enabled by mobile device 100. This may be done by querying the underlying communication framework of mobile device 100. Alternatively, the underlying communication framework may notify the user interface module 420 of the relevant connection statuses upon initialization and upon a change of connection status, without a query having to be made. The result of such connection status queries or notifications yields one of two connection states: “active”; and “inactive”. These connection states are applicable to both the WLAN and cellular network connections although they may be graphically expressed in different ways.
Field 622 is used for displaying a “Wi-Fi” icon in one of two possible states: dimmed and emphasized, corresponding to inactive and active WLAN connections, respectively. Field 622 is thus a WLAN field indicative of the WLAN network connection status. Field 624 is a network technology field and field 626 is a signal strength field for indicating the relative signal strength of either the WLAN connection or the cellular connection.
In a first scenario, the user of mobile device 100 may be traveling with the mobile device 100 outside of the range of communication of any WLAN. Thus, the Wi-Fi icon in field 622 is shown to be dimmed to indicate that Wi-Fi is enabled but is not connected to a network. Thus, the Wi-Fi connection is, in effect “inactive”. In this scenario, it is assumed that the mobile device 100 is within range of a cellular base station and is therefore in connection with the cellular network. Accordingly, field 624 displays an icon indicative or descriptive of the network technology through which the cellular network connection is established. In this scenario, carrier voice, carrier data, internet services and email services are all supported through the cellular network connection.
In the example illustrated in FIG. 6, field 624 contains the descriptive icon “EDGE”. Depending on the network technology of the telecommunications carrier providing the cellular connection, field 624 may alternatively display a descriptive icon such as “GPRS” or another such descriptive indication of the network technology. Alternatively, instead of a descriptive indication in field 624, a symbolic indication, such as may be recognized as being associated with a particular network technology, may be used.
In the example shown in FIG. 7, network technology field 624 displays the descriptive icon “UMA” to indicate that the network technology employed by the WLAN connection is the UMA. Because there is a WLAN connection employing UMA, the signal strength icon displayed in field 626 is a different signal strength icon to that illustrated in FIG. 6 for a normal cellular network connection. The signal strength icon shown in field 626 in FIG. 7 is only shown where the network technology is UMA. In this scenario, all services (i.e. carrier voice, carrier data, internet services and email services) can be accessed through the WLAN using UMA and therefore there is no need to access any of these services through a cellular connection.
A fourth scenario may be illustrated with reference to FIG. 8, which shows a further icon combination in fields 622, 624 and 626. In this fourth scenario, the user may be carrying mobile device 100 at work, where for security reasons, the corporate environment has a firewall established against UMA connections. In such a case, the carrier voice, carrier data and internet services may be accessed through the cellular connection, while the corporate email services can be accessed through the local WLAN connection. Accordingly, it is necessary to show that the Wi-Fi connection is active by showing an emphasized Wi-Fi icon in the WLAN field 622 and also to show that the cellular connection is active by providing a descriptive icon such as “EDGE” in network technology field 624. As the dominant wireless services connection is cellular, the signal strength icon displayed in field 626 is specific to a cellular connection, rather than a WLAN connection.
In a fifth scenario illustrated with reference to FIG. 9, the mobile device 100 may be out of range of a cellular basestation, but within range of a WLAN connection. This may occur, for example, where the user has a local wireless router at home that is connected through a cable or a landline to a public network, although the home may be outside of cellular range. In this scenario, carrier voice, carrier data and internet services may be unavailable to mobile device 100, although email services may be available via the Wi-Fi connection to the local wireless router.
