Definitions
- the present invention relates to telecommunications terminals.
- the invention relates to a structure for a telecommunications terminal which allows the same structure to be used for terminals having different functionalities .
- a typical fixed radio telecommunications terminal may have a radio transceiver, a radio system interface, a user interface, including a keypad, a microphone and a loudspeaker, and connecting logic units.
- the present invention seeks to provide a structure which can be used to offer telecommunications terminals having a range of functionality. More specifically, the invention provides a modular structure for a telecommunications device.
- Embodiments of the invention may provide a telecommunications device having a bus, to which different modules may be connected as desired.
- a telecommunications terminal comprising a communications bus, a radio module which is connected to the communications bus and which is operable to receive and transmit radio telecommunications signals and transmit radio telecommunications signals, and a plurality of connection modules which are connected to the communications bus in parallel to one another and to the radio module and which are operable to connect the terminal to respective telecommunications networks, the radio module also being operable to communicate with at least one of the connection modules via the communications bus.
- FIG. 1 is a schematic diagram illustrating the structure of a telecommunications terminal in accordance with an embodiment of the present invention. DETAILED DESCRIPTION OF THE DRAWINGS
- FIG. 1 shows the architecture of a telecommunications terminal 2 embodying the present invention.
- the terminal 2 includes a communications bus 21, a radio module 22, a line connection module 23, and a control module 24. Also connected to the bus 21 is a man-machine interface 25.
- the radio module 22, the line module 23, and the control module 24 are connected in parallel to, and communicate with one another via, the communications bus 21.
- the communications bus is a standard open communications bus.
- the bus could be the universal standard bus (USB) and can provide a highly flexible base for carrying both data and telephony information between the modules in the terminals.
- USB universal standard bus
- the radio module 22 contains the air interface function for interfacing with the desired radio telecommunications network. Specifically, the radio module 22 has a connection to an antenna 221, transceiver circuits 222, associated control logic 223 in the form of hardware and/or software, and an interface 224 to the communications bus.
- the radio system could for example relate to a digital enhanced cordless telephony system such as DECT, CT2 , or CT3.
- the transceiver circuits 222 under the control of the logic circuits 223, converts signals received from the bus 21 into a form suitable for transmission over the air interface, and vice versa.
- the line module 23 includes the relevant functionality required to connect to fixed telecommunication systems, namely an interface circuit 231, together with a bus interface device 232 and connecting logic 233 in hardware and/or software.
- the telecommunication system supported by the module could for example be an integrated services digital network.
- the interface circuit 23 under the control of the logic circuits 233, converts signals received from the bus 21 into a format suitable for transmission over the fixed network, and vice versa.
- Control terminal of the terminal resides in the control module 24, which includes a bus interface 241 and a processor 242 with appropriate associated memory devices .
- the man-machine interface 25 also includes a bus interface 251, but is otherwise generally conventional, in that it includes a keypad 252 for receiving data input by a user, a microphone 253 for receiving speech from a user, and a loudspeaker 254 for providing audio outputs to a user, all under the control of a control circuit 255.
- the radio module 22, and line connection module 23 are removable and replaceable.
- the bus has connections 26, 27, etc. for other radio modules and line connection modules providing different functionality.
- line connection modules might provide a connection to a plain old telephony system (POTS) , or an ethernet connection to a LAN.
- POTS plain old telephony system
- radio modules might provide a connection to a personal handyphone system (PHS) a digital advanced mobile phone system (D-AMPS) , a wide band CDMA system (W-CDMA) or the Qualcomm CDMA system (IS-95) .
- PHS personal handyphone system
- D-AMPS digital advanced mobile phone system
- W-CDMA wide band CDMA system
- IS-95 Qualcomm CDMA system
- modules can easily be devised for connection to the connections 26, 27 of the terminal 2, such as an uplink module for cable TV, a CCTV surveillance system or other such devices.
- an embodiment of the present invention splits the functionality of the terminal into stand alone modules which are interconnected by the standard bus .
- the user is able to obtain a telecommunications terminal which provides the functionality which he requires.
- the terminal can be provided with the necessary modules to allow these options.
- the architecture of the present invention can provide a low cost hardware solution to the problem of supplying devices with such a wide range of functionality because it can make use of high volume standard components which are able to be used with many different functional devices.
- the structure of the present invention has several clear benefits over the prior art devices.
- Terminals in accordance with the invention can provide clear interfaces between different services and functions, which can allow short lead times when developing new functionality, and can support parallel development projects, because it is only necessary to consider the new functionality in isolation, rather than having to consider its impact on other features of the device, as would be necessary in an integrated device.
- such a terminal can reuse old functionality and integrate many different systems into a single terminal.
- the user can add new modules and features as required, making it easy to expand the functionality of such a system.
