Description
Customer premises equipment TECHNICAL FIELD
The present invention relates to a customer-premises equipment (CPE) operatively connectable to at least one computer unit and arranged for communicating data be- tween said at least one computer unit and a modem unit at a service provider part.
BACKGROUND
Even if it is common today to have broadband also for private end users, analogue modems (circuit switched) are still used e.g. to connect to a bank office. This works fine when there is a direct connection between the analogue modem and the Public Switch Telephone Network (PSTN), i.e. the analogue network. However, if a wireless CPE (Customer-Premises Equipment or Customer-Provided Equipment) with data router and voice gateway functionality is to be used, problems arise with jitter and delays mainly arising from the communication line between the personal computer of the end user and the CPE of the end user via the analogue modem. This in turn, results for example in dropped calls.
The present invention intends to solve or at least decrease the above mentioned problems with jitter and delays.
US 6 915 142 describes an example of a wireless modem arranged to communicate with a wireless network. An interface unit is arranged to interface a host device with the wireless network through the wireless modem and to interface a portable com- puting device with the wireless network through the wireless modem.
SUMMARY

BRIEF DESCRIPTION OF THE DRAWINGS
Fig 1 shows schematically an example of a system comprising a subscriber part, a communication channel part and a service provider part.
Fig 2 shows schematically an example of the subscriber part shown in fig 1.
DETAILED DESCRIPTION
In fig 1, a system 1 for communicating data between a subscriber and a provider comprises a subscriber part 2, a communication channel part 3 and a service provider part 4.
The subscriber part 2 comprises in the shown example a personal computer 5 connected to a customer-premises equipment 6 or customer-provided equipment (CPE). The personal computer 5 is connected to the customer-premises equipment 6 by means of a communication line 7. The communication line 7 will be described more in detail later.
The communication channel part 3 comprises antenna 8 arranged to transmit and/or receive radio waves. The antenna 8 is comprised in or connected to the customer- premises equipment 6. The antenna 8 is arranged to transmit a data call over a radio network 9 to a core network 10. The radio network 9 is for example GSM, EDGE5 GPRS, CDMA, WCDMA, HS(D)PA etc. The core network 10 is arranged to transmit the data call to a Public Switch Telephone Network (PSTN) gateway 11. The PSTN gateway 11 is arranged to convert the data call to an analogue call. The PSTN
gateway 1 1 is further arranged to feed the converted analogue call to a Public Switch Telephone Network (PSTN) 12. The Public Switch Telephone Network (PSTN) 12 is arranged to transmit the analogue call to a modem unit 13 having a telephone number associated thereto. The modem unit 13 is in the illustrated exam- pie comprised in the service provider part 4. In one example, the modem unit 13 comprises one single modem. In another example the modem unit comprises a modem pool. The service provider is for example a bank office.
In fig 2. the personal computer 5 comprises an application 21 which at request is to be in communication with the modem unit 13 at the service provider part 4. A virtual serial port 22 supported by a virtual serial port driver 15 provides a connection to a communication port 14 in the personal computer 5. Virtual serial port drivers are well known today and can for example be downloaded by Internet. The virtual serial port driver 15 is arranged such that the virtual serial port 22, from the applica- tion 21 point of view, appears to be a conventional serial port connected to a modem. In reality, the virtual serial port 22 is arranged to transport serial communication between the application 21 and the communication port 14 on the personal computer.
The customer-premises equipment 6 comprises a communication port 16 via which a virtual serial port server 17 in the customer-premises equipment 6 is in communication with the communication port 14 of the personal computer. The communication ports 14, 16 are in communication via a communication channel 7. The communication channel 7 between the personal computer 5 and the customer premises equipment 6 is in one example provided using the Transmission Control Protocol (TCP/IP). However, the communication channel 7 can be provided using any other wired or wireless data link protocol.
The customer-premises equipment 6 comprises further a call proxy unit 18 and a ra- dio unit 19. The call proxy unit 18 comprises a call signalling proxy part 18a ar-
ranged to set up and/or end a call. The call signalling proxy part 18a is arranged to interpret and, if necessary, rewrite call signalling messages and forward them to the radio unit 19. Accordingly, in order to dial up the modem unit 13 of the service provider part 4. the application 21 is arranged to send a call signalling message to the customer-premises equipment 6 via the communication ports 14 and 16. The call proxy unit 18 is arranged to detect reception of messages of said call signalling type. Upon detection of reception of a call signalling message, the call proxy unit 18 is arranged to activate the call signalling proxy part 18a. The call signalling message, interpreted and possibly rewritten, is then fed to the radio unit 19 via a port 20. The radio unit 19 is arranged to transmit the call signalling message to the modem unit 13 via the antenna 8. To be more specific, the port 20 sets up a data call by instructing the PSTN to call the telephone number extracted from the call signalling message. Thereby a direct connection is provided between the application 21 of the personal computer 5 and the modem unit 13. The data call is for example a circuit switched data call.
In reverse, in an example wherein the modem unit 13 of the service provider part 4 is arranged to dial up the application 21 of the personal computer 5. the modem unit 13 of the service provider part 4 is arranged to send a call signalling message through the communication channel part 3 to the customer-premises equipment 6. The radio unit 19 of the customer-premises equipment 6 is arranged to receive the call signalling message via the antenna 8. The call signalling message is then fed to the call proxy unit 18 via the port 20. The call proxy unit 18 is arranged to detect reception of messages of said call signalling type and to, upon detection, activate the call signalling proxy part 18a, as described above. The call signalling message, interpreted and possible rewritten by the call signalling proxy part 18a, is then fed to the communication port 16 over the virtual serial port server 17. The call signalling message is then transmitted via the communication ports 16, 14 to the personal computer 5. In the personal computer 5, the call signalling message is fed to the ap- plication 21 via the virtual serial port 22. Upon reception of the call signalling mes-
sage, the call to the application 21 has been set up. Thereby, a direct connection is provided between the modem unit 13 and the application 21 of the personal computer 5.
In one example, the communication channel 7 and the port 20 use different call signalling protocols. In accordance with this example, the signalling data proxy part 18a comprises a conversion module arranged to provide said conversion, The call signalling protocol used over the communication channel 7 is for example AT commands following the specification of the so called Hayes Command Set. The call signalling protocol expected by the port 20 is for example a proprietary call signalling protocol. In another example, the communication channel 7 and the port 20 use the same call signalling protocol. Then, a conversion module is excessive.
The call proxy unit 18 further comprises a call data proxy part 18b. When a direct connection has been provided between the application 21 and the service provider, the call proxy unit 18 is arranged to relay call data via the call data proxy part 18b between the application 21 of the personal computer 5 and the service provider. In one example, the call data proxy part 18b is arranged to relay call data transparently without any interpretation of the data. The direct connection is maintained until the subscriber (i.e. application 21) or provider ends the connection.
In one example, the communication channel 7 and the modem unit 13 use different call data protocols. In accordance with this example, the call data proxy part 18b comprises a conversion module arranged to provide said conversion. In another ex- ample, the communication channel 7 and the modem unit 13 use the same call data protocol. Then, a conversion module is excessive. The he call data protocol is for example a so called Point-to-Point Protocol (PPP).
hi an alternative example (not shown), the radio unit 19 is arranged to handle set up of calls and subsequent direct connections to a plurality of applications, hi one ex-
ample in accordance therewith, the applications are implemented in one common personal computer. Alternatively, the applications are implemented in different personal computers. In another example in accordance therewith, the plurality of applications are arranged to be connected to the same modem unit. Alternatively, the plu- rality of applications are arranged to be connected to different modem units.
