The network-based wireless telephone communication device according to the invention is disclosed in full details by way of preferred embodiments in the following with reference to the accompanying drawings.
FIG. 1 is a schematic diagram showing the application of the network-based wireless telephone communication device of the invention 100. In practical implementation, the network-based wireless telephone communication device of the invention 100 can be either an independent device or integrated to a portable information platform 10, such as a mobile phone, an electronic dictionary, a PDA (Personal Digital Assistant), or the like, for the purpose of allowing the user to carry out an interactive multi-person voice communication session within the hot spot (i.e., wireless coverage) of a wireless network access point 20 via a network system 30, such as the Internet, with one or more remotely-located persons having network-linked voice communication platforms, such as a mobile phone 41, a notebook computer 42, or a desktop computer 43. The interactive multi-person voice communication session allows the user to talk concurrently with these remotely-located persons in a two-way interactive manner.
As shown in FIG. 2, the object-oriented component model of the network-based wireless telephone communication device of the invention 100 comprises: (a) a user interface module 110; (b) a wireless network interface module 120; (c) a callee specifying module 130; (d) an instant interactive voice conferencing control module 140; (e) an input-voice processing module 150; and (f) an output-voice processing module 160.
The user interface module 110 is functionally related to the keypad 11 and the display screen 12 (or equivalent input/output devices) on the portable information platform 10, which allows the user to activate the network-based wireless telephone communication device of the invention 100 for an interactive multi-person voice communication session and specifying related settings.
The wireless network interface module 120 is, for example, a WLAN (Wireless Local Area Network) compliant module or a Bluetooth-compliant module, which is capable of linking via wireless channel to the wireless network access point 20 for the purpose of linking the network-based wireless telephone communication device of the invention 100 via the wireless network access point 20 to the Internet 30. Since WLAN and Bluetooth are both well-known wireless communication protocols in the information industry, detailed description thereof will not be given here in this specification.
The callee specifying module 130 is coupled to the user interface module 110 to allow the user to utilize the user interface module 110 to specify the network ID of each callee whom the user wants to talk with. The user can specify one or more callees at the same time. This task can be done by either selecting each desired network ID from a prestored list, or directly inputting each desired network ID via the keypad 11.
The instant interactive voice conferencing control module 140 is, for example, an ICQ program, an MSN Messenger program, a Yahoo Messenger program, or an equivalent program, which is capable of controlling the interactive multi-person voice communication session between the portable information platform 10 and the network-linked voice communication platforms 41, 42, 43 when the portable information platform 10 is linked through the wireless network interface module 120 and the wireless network access point 20 and via the Internet 30 to each of the network-linked voice communication platforms 41, 42, 43 whose respective network IDs are specified by the callee specifying module 130.
The input-voice processing module 150 is externally coupled to a microphone 151 used to pick up the user's natural voice, and which is capable of converting the user's natural voice into digital voice signals in a specific format.
The output-voice processing module 160 is externally coupled to a loudspeaker 161, and which is capable of receiving each callee's returned digital voice signals from the instant interactive voice conferencing control module 140 that are received through the wireless network interface module 120 and the wireless network access point 20 and via the network system 30 from each of the network-linked voice communication platforms 41, 42, 43, and then converting each callee's returned digital voice signals into analog signals that can be reproduced through the loudspeaker 161 into natural voice.
During practical application, when the user wants to talk with one or more persons via the portable information platform 10 (in the following example, assume the user wants to talk with 3 persons at the same time), the user needs first to utilize the user interface module 110 to activate the network-based wireless telephone communication device of the invention 100 for linking by way of the wireless network interface module 120 to the wireless network access point 20 for connection to the Internet 30. When the portable information platform 10 is successfully connected to the Internet 30, the user can then utilize the callee specifying module 130 to specify the respective network IDs of the callees whom the user wants to talk with, and this action will activate the instant interactive voice conferencing control module 140 (which is ICQ, MSN Messenger, Yahoo Messenger, or an equivalent program) to establish a link via the Internet 30 to each callee's network-linked voice communication platform 41, 42, 43.
As the portable information platform 10 is successfully linked to each of the network-linked voice communication platforms 41, 42, 43, the user can then speak against the microphone 151, which will activate the input-voice processing module 150 to convert the user's natural voice message into digital voice signals in a specific format for the instant interactive voice conferencing control module 140 to send the digital voice signals by way of the wireless network interface module 120 and the wireless network access point 20 and via the Internet 30 to all of the network-linked voice communication platforms 41, 42, 43, allowing the user's voice to be broadcast to all the callees through their network-linked voice communication platforms 41, 42, 43. Each callee can also talk back to the user via the mobile phone 41, the notebook computer 42, or the desktop computer 43.
Reversely, each callee's voice will be transferred back in digital form via the network-linked voice communication platforms 41, 42, 43 and by way of the Internet 30 and the wireless network access point 20 to the user's portable information platform 10, which is then received and demodulated by the wireless network interface module 120 into digital voice signals and then forwarded by the instant interactive voice conferencing control module 140 to the output-voice processing module 160 for reproduction through the loudspeaker 161 into natural voice for the user to hear the callee's returned voice message.
In conclusion, the invention provides a network-based wireless telephone communication device, which can be either an independent device or integrated to a portable information platform, for the purpose of providing an interactive multi-person voice communication session for the user to talk with one or more other persons via voice over the Internet. Since the invention utilizes the Internet for voice data transmission, it is significantly more economical to use than mobile phone. Moreover, since the invention can be either an independent device or integrated to a portable information platform, such as mobile phone, electronic dictionary, PDA, or the like, it has a higher level of portability than notebook computer with wireless linking capability. The invention is therefore more advantageous to use than prior art.
