HOME GATEWAY SYSTEM AND METHOD

Field of the Invention

The present invention relates to the field of communication systems and more particularly to a home gateway system and method .

Background of the Invention

Home owners often have a variety of machines for receiving information services, such as a cable receiver box, several telephones, an answering machine, a caller ID box, a home Local

Area Network (LAN), and a dial up connection to the internet. Each information carrier feels compelled to have their own software and hardware. Presently all these different machines operate separately and often redundantly. These information carriers are now offering each other's products. Cable television operators want to provide the home owner with telephone service, while telephone companies want to provide cable television services. Satellite television services want to offer high speed connections to the internet. The user is often overwhelmed by the multitude of choices and is not interested in learning the different- - 2 -

hardware and software requirements for each of these different carriers of information.

Thus there exists a need for a home gateway system that can integrate the functions of these various devices, so that a user need not concern himself with the particular carrier providing the service.

Detailed Description of the Drawings

A home gateway system provides a way of integrating all the information carrying needs of a home owner. One embodiment of a home gateway system includes a transceiver connected to a switch. A processor is connected to the switch and provides intelligent functions for the switch. A router is connected to the switch. The router upon receiving a data packet from an internal port with an external address, routes the data packet through the switch to the processor. The processor directs the transceiver to establish a telephony connection with an internet service provider and sends the data packet to the internet service provider. The transceiver can also be used to establish a communication channel over a wireless local loop. A voice processing and caller ID system can be connected to the processor to provide telephony answering and screening services. The home gateway system can integrate many of the functions of telephone systems, local area networks, internet dial up services, cable television services, and satellite television service. FIG. 1 is a schematic diagram of a home gateway system 20 connected to a variety of information carriers in accordance with one embodiment of the invention. The home gateway system 20 is located inside a house 22. The home gateway system 20 has an input to receive a cable television 24 input signal. The home gateway system 20 is also connected by a wireless local loop 26 and a base station 28 to the public switch telephone network (PSTN) 30. The antenna 32 for the wireless local loop 26 is shown in the attic of the house. The PSTN 30 provides access to an - 7 -

internet service provider (ISP) 34, which provides access to the internet 36. A telephone 38, television 40, computer 42 and printer 44 can all be connected to the home gateway system 20. The home gateway system 20 allows the computer 42 to talk to the printer 44 or to the ISP 34. The telephone 38 can place a standard telephone call over the PSTN 30 or place a data telephone call over the internet 36.

FIG. 2 is a block diagram of a home gateway system 20 in accordance with one embodiment of the invention. The home gateway system has a transceiver 50 capable of establishing a telephony connection 52 with an internet service provider 34. The transceiver is connected to a switch 52. The switch 52 is connected to a processor 54 and a router 56. The switch 52 in one embodiment is connected to a plurality of telephones and can provide switched connections between the plurality of telephones in the house. The router 56 can be connected to a variety of data devices such as computers, printers, scanners and facsimile machines. A data telephony connection can also be established through the router 56. In order to establish a data telephony connection, the router receives a request for internet telephone connection from an internal port. The request is routed by the . router through the switch 52 to the processor 54. The processor 54 determines that the request requires establishing a session with an internet service provider 34. The processor 54 directs the transceiver 50 to establish a telephony connection with the internet service provider 34, by sending a command including the internet service providers telephone number to the transceiver 50. The processor 54 then establishes a communication session with the internet service provider. Once the telephony connection and session are established the telephone phone proceeds normally. The voice signal is encoded into data packets for transmission over the internet. The ISP 34 upon receiving a request for a data telephony connection can route the information to an internet phone service provider. The internet phone service provider routes the call over the internet to a PSTN switch (POP point of presence) closest to the destination number. The PSTN switch routes the last part of the call in a standard manner. The router upon receiving a data packet from an internal port with an external address, sends a request to the processor to establish communication session. The processor directs the transceiver to establish a telephony connection with an internet service provider (ISP). Once the communication session is established data packets are routed to the ISP.

FIG. 3 is a block diagram a home gateway system 20 in accordance with another embodiment of the invention. In this embodiment the transceiver 50 establishes a wireless local loop connection 60 with a base station 62. The base station 62 can route a call to an internet service provider 64. The transceiver 50 is again connected to a switch 52. The switch 52 is connected to. a processor 54 and a router 56. The switch 52 also has a plurality of input lines 66. Telephones, facsimile machines and modems are among the devices that can be connected to the switch 52. The router 56 is shown with several inputs 68. The router 56 allows a user to establish a local area network within his home. The router 56 in this embodiment is connected to a television processing system 70. The television processing system 70 is able to receive electronic messages through the router 56 and to transmit this information through a cable 72 to a channel of a television. The television processing system is also connected to an emergency broadcast system (EBS) receiver 74. The EBS receiver 74 receives emergency information and passes this information to the television processing system 70. The television processing system 70 then displays this information on a channel of a television. In one embodiment the television processing system receives an email request from a user. The user provides the request by using the remote control of the television. The television processing system then passes the request through the router and switch to the processor. The processor then directs the transceiver to setup a connection with an ISP and download the user's email. The email is then displayed on the user's television. In one embodiment of the home gateway system 20 the switch 52 has a data telephony input as one of the plurality of inputs 66. When a user picks up a phone connected to the data telephony input and dials a destination address, the switch 52 sends a query to the processor 54. The switch 52 in one embodiment triggers based on receiving an off hook signal from the data telephony input. In another embodiment the switch 52 . triggers based on receiving a destination address (e.g., telephone number or IP address). The response of the switch 52 to a trigger event is to send a query to the processor 54 asking for further processing instruction. In this case the query would include the destination address. The processor 54 then sends a response to the switch that includes an internet phone provider number. The switch then passes the internet phone provider number and the - 10 -

destination address to the transceiver 50. The transceiver establishes a telephony connection with the internet phone provider 64. The processor then establishes a communication session with the internet phone provider. The interment phone provider 64 then establishes a data telephony connection over the interment to the destination address.

FIG. 4 is a block diagram a home gateway system 20 in accordance with another embodiment of the invention. A wireless transceiver 50 has an antenna 80 and is capable of establishing a wireless local loop 60 connection with a base station 62. A wireless local loop is a telephony connection between the PSTN and a subscriber's home. The wireless local loop is an alternative to a standard wired local loop connection. A single base station 62 will generally cover an entire neighborhood. In one embodiment the base station 62 to subscriber link is a point to multi-point

(broadcast) link. The link from the subscriber's house to the base station 62 is a point to point link. These links are not mobile links, but geographically stable. This simplifies the processing of a wireless local loop compared to a mobile (cellular, PCS) telephone link and allows for lower cost, higher quality telephone links.

The wireless transceiver 50 is connected to a switch 52 as . in the previous embodiments. The switch 52 in this case is connected to a voice bridge 80, as well as the processor 54 and the router 56. The processor 54 is connected to a smart card interface 82, a voice processing system 84 and a caller identification system

86. The router is connected to the television processing system 70 and to a home automation and security system 88. - 11 -

The smart card interface 82 is used to store and download various user preferences or setups. The voice processing system 84 includes a complete voice mail system and a voice recognition and speech synthesis system. The voice processing system 84 in combination with the switch acts as an electronic receptionist for an incoming phone call. In addition, the voice processing system is used for voice activated dialing. The caller identification system logs incoming calls and is used for call screening. In one embodiment all calls not on a preferred list are routed to the voice mail of the voice processing system 84. This requires the switch

52 to query the processor 54 how to route incoming calls. The voice bridge 80 is used to setup three way calls (conference calls).

The home automation and security system 88 can send messages through the router to a computer, television processing system or have the wireless transceiver 50 place a call to emergency personnel. The smart card interface is used to setup various appliances and to turn on or off lights. A user can call in commands to the home automation and security system 88 by using the speech recognition technology of the voice processing system 84. The voiced command is recognized and converted into a data command that the home automation and security system . 88 understands. In one embodiment the user's voice is authenticated by a speaker recognition system in the voice processing system 84, before a voiced command will be obeyed. FIG. 5 is a block diagram of a voice processing system 84 used in a home gateway system in accordance with one embodiment of the invention. The voice processing system contains a speech recognition system 100, a speaker verification - 12 -

system 102, a speech synthesis system 104 and a voice mail memory system 106. The control of the systems of the voice processing system 84 is performed in one embodiment by the processor 54. The processor 54 coordinates the voice system 100- 106 to provide machine reception and voice mail capabilities for instance.

FIG. 6 is a block diagram of a transceiver 50 used in a home gateway system in accordance with the one embodiment of the invention. The transceiver has a duplexer 120 that isolates the incoming signals from the outgoing signals based on their frequencies. Outgoing analog voice signals are first encoded by a vocoder 122. The vocoder 122 converts the analog voice signal to a digital voice signal. Some outgoing signals will be digital signals, if for instance the user is using a digital cordless telephone in the house. Digital voice signals will generally be passed on to the multiplexer 124, however in some circumstances the digital voice signal is compressed by a data compression circuit 126. When the signal is a data signal it may also be compressed. All the outgoing signals are then multiplexed together by the multiplexer 124. The multiplexer 124 in one embodiment time division multiplexes the outgoing signals. In another embodiment the multiplexer 124 wavelength division multiplexes the outgoing signals. In another embodiment the multiplexer 124 code division multiplexes the signals. The multiplexing scheme chosen depends on the requirements of the wireless local loop. The outgoing signals are then modulated by the modulator 127. Then the outgoing signals are up converted by a carrier signal 128 at a mixer 130. A - 13 -

processor 132 controls the multiplexer 124 and receives certain control information.

The incoming signals are first down converted by a local oscillator signal 134 at the mixer 136. The incoming signals are then demodulated by a demodulator 138. A demultiplexer 140 then demultiplexes the incoming signals. When the incoming signals are compressed, they are expanded by the data compression circuit 126. When a digitized voice signal needs to be converted to an analog voice signal, the vocoders 122 perform this function. The incoming signals are then passed to the switch.

FIG. 7 is a schematic diagram of a wavelength division multiplexing scheme 150 used in a home gateway system in accordance with one embodiment of the invention. The diagram shows a plurality of wavelength division multiplexed channels 152 and a control channel 154 carried by separate wavelengths

(frequencies) WO through W24 156.

FIG. 8 is a schematic diagram of a time division multiplexing scheme 160 used in a home gateway system in accordance with one embodiment of the invention. The diagram shows a plurality of time division multiplexed channels (chO, chl, . . .ch24) 162 carried at different time slots (T₀, T, , . . . T₂₄) .

FIG. 9 is a schematic diagram of a code division multiplexing scheme 170 used in a home gateway system in accordance with one embodiment of the invention. The diagram shows a plurality of channels 172 carried on different codes (CD0, CD1 . . . CD24)

174. The codes are used to modulate the channels and the channels can be recovered by demodulating with the appropriate - 14 -

codes. Commonly the wireless local loop would have two to four voice channels and a control channel.

FIG. 10 is a schematic diagram of a derive lines scheme 180 used in a home gateway system in accordance with one embodiment of the invention. In one embodiment, the wireless local loop supports two telephone lines. When both telephone lines are in use, the derive lines technique can divide one of the lines in two and create three lines or the total bandwidth can be reallocated among the three lines. In the embodiment shown in figure 10, an up-link line 182 transmits for a time slot. The down link channel 184 also transmits for one time slot. The derive lines scheme compresses the existing signal by a factor of 1/2 and also compress the new signal by 1/2. Then the up-link time slot is divided in half, so that there is a first uplink time slot 186 and a second uplink time slot 188. The down-link time slot is also divided in half, so that there is a first down-link time slot 190 and a second down-link time slot 192. While the derived lines scheme is described in conjunction with a time division multiplexing scheme, it can also be implemented with a wavelength division multiplexing scheme or a code division multiplexing scheme.

FIG. 11 is a flow chart of a method of operating a home gateway system to provide a data telephony connection in accordance with one embodiment of the invention. The process starts, step 200, by connecting a telephone to a data telephony interface of the home gateway system at step 202. Next, a destination telephone number is dialed at step 204. A switch of the home gateway system triggers on a call request and sends a query to a processor of the home gateway system at step 206. A - 15 -

reply is received from the processor that includes a telephone number of an internet service provider at step 208. At step 210 a telephony connection is established with the internet service provider. A message is sent to the internet service provider that includes the destination telephone number at step 212, which end the process at step 214.

In one embodiment the step 210 of establishing a telephony connection includes establishing a wireless local loop connection to a base station. The base station connects the call to the internet service provider.

FIG. 12 is a flow chart of a method of operating a home gateway system to provide a data telephony connection in accordance with another embodiment of the invention. The process starts, step 220, by receiving a request at step 222. When the request is received at a router and requires an external connection, the request is passed to a processor at step 224. A command is sent to a transceiver to establish an external connection at step 226. At step 228 a wireless local loop connection to a base station is established. A telephony connection to a service provider is established at step 230, ending the process at step 232.

In one embodiment the step 226 includes an asymmetrical data service indicator. In this case the transceiver establishes an asymmetrical data link (ASDL) with the base station. ASDL can be particularly advantageous when the user is surfing the World

Wide Web. ASDL divides the bandwidth of a telephone line(s) into a low bandwidth channel from the home to the ISP and a high - 16 -

bandwidth channel from the ISP to the home. This allows large amounts of graphical data to be downloaded to the user quickly. In another embodiment after the telephony connection to the service provider is established, a plurality of data packets are received for transmission over the external connection. The priority of the plurality of data packets is determined. Those data packets having a high priority (high priority data packets) are sent before any low priority data packet are transmitted. In another embodiment the low priority data packets are compressed to form a plurality of compressed data packets. The compressed data packets are then multiplexed with the high priority data packet over the external connection.

In another embodiment the request is an information service provider request. The request can be for traffic, weather, travel or other information stored on a web site. The information may come from the internet or a telephone information system. The user can request this information through his television and in this case the received information is displayed on a channel of his television. The user can also request this information from his computer or his telephone and in that case the information is sent back to the device originating the request. Using the voice processing system it is possible to convert data to voice or voice to data so that any information source can be translating into the appropriate form for the requesting device. FIG. 13 is a flow chart of a method of operating a home gateway system to provide a data telephony connection in accordance with another embodiment of the invention. The process starts, step 240, by receiving a destination number from a - 17 -

data telephony interface. A telephony connection with an ISP is established at step 244. A message is then sent to the ISP that includes the destination number (DN) at step 246. An audio signal is received and digitized by the home gateway system at step 248. In one embodiment the signal is also compressed. The digitized signal is then packetized to form a plurality of outgoing packets and transmitted to the ISP at step 250. In one embodiment the packets have an associated priority and high priority packets are transmitted first. The home gateway receives incoming packets (plurality of incoming packets) at step 252. The incoming packets are converted into an incoming audio signal (digital or analog) at step 254. The incoming audio signal is sent to the telephone at step 256 which ends the process at step 258.

FIG. 14 is a flow chart of a method of operating a home gateway system in accordance with one embodiment of the invention. The operation starts, step 270, when a request is received at step 272. At step 274, it is determined if the request is for a switch 276 or a router 278. When the request is for a switch 276, it is determined if the request is for a data telephony connection at step 280. When the request is not for data telephony connection, other standard switch processing is performed at step 282. Standard switch processing can include internal routing of phone calls or routing to the voice messaging system for instance. When the request is for a data telephony connection it is established at step 284.

When a request was for a router 278, it is determined if the request requires an external connection at step 290. When the request does not require an external connection, standard routing ^" - 18 -

functions are performed at step 292. Standard routing functions include passing data between computers, computers and printers or fax machines for instance. When the request requires an external connection, it is determined if the request is for an asymmetrical data link 294, or a standard link 296 or an ISP information service 298. When the request is for an asymmetrical data link (ASDL), the transceiver establishes an ASDL link with an ISP. When the request is for a standard link, determining a priority of the data to be sent at step 300. When the priority is high, the data is sent immediately at step 302. When the priority is not high, the data is compressed at step 304. The low priority data is multiplexed with the high priority data at step 306. In another embodiment, the low priority data is stored until all the high priority data has been sent and then sending the low priority data at step 308.

FIG. 15 is a block diagram of a home gateway system 20 with telephony functions in accordance with one embodiment of the invention. In this embodiment a switch 320 is connected to an external telephony channel 322 and an internal telephony channel (plurality of internal telephone lines) 324. In one embodiment the external telephony channel 322 is an xDSL (Digital Subscriber Line) link with a central office, such as an ADSL (Asymmetrical digital Subscriber Line) Link. The xDSL link provides one or more derived digital voice channels as described in the copending application, U.S. serial

No. 08/742,164, entitled "Method and Apparatus for Providing a derived Digital Telephone Voice Channel", filed on November 1, 1996, assigned to the same assignee as the present - 19 -

invention and the subject matter which is incorporated herein by reference thereto. The external telephony channel 322 using the invention described in the above referenced application provides a plurality of digital derived telephone channels and a data channel of such an ADSL link. A processor

326 is connected to the switch 320. The processor (controller) 326 sends and receiving messages from the switch 320. A caller identification system 328 is connected to the processor 326. The caller identification system 328 receives an identify query from the processor 320. Once the incoming telephone call number has been identified the switch can route the call based on some predetermined criteria. For instance, calls not on a preferred list could be routed to a voice mail box. In this embodiment the home gateway system 20 can be connected to a standard telephone line.

In one embodiment, the switch 320 allows the owners to make "intercom" type calls. When an intercom call command (e.g., dialing an internal extension) is received, the calling line is connected with another internal phone line. In another embodiment the switch acts as an electronic receptionist. The caller is given a plurality of options (e.g., users' extensions) and the switch routes the incoming call to one of the plurality of internal telephone lines based on the caller response.

FIG. 3 is a block diagram of a home gateway system 20 with telephony functions in accordance with one embodiment of the invention. In this embodiment the home gateway system 20 has a transceiver 340 capable of establishing a wireless local loop connection 342. A voice processing system - 20 -

344 is coupled to the transceiver 340. The voice processing system 344 is capable of storing a message from an incoming call. A caller identification processing system 346 coupled to the transceiver 340. The caller identification processing system 346 determines a telephone number of the incoming call. If the telephone number belongs to a screened group of telephone numbers, routing the incoming call to the voice processing system 344. The voice processing system 344, in one embodiment, provides a list of voice synthesized options to the caller. For instance, the voice processing system might announce the voice mail boxes for each member of the family. In one embodiment, the user may be asked to speak the name of the family member they wish to leave a message. A speech recognition unit in the voice processing system 344 then recognizes the spoken name and connects the caller with the family member's voice mail box.

In one embodiment, the home gateway system has a processor coupled to the transceiver 340. The processor determines if an incoming call is received during an existing call. When the incoming call is received during an existing call, an indicia is posted of the incoming call to a user. The indicia can be a light, or a beep over a speaker separate from the telephone line. This provides the user the functionality of call waiting without the obnoxious beep during the telephone conversation.

FIG. 17 is a flow chart of a process of voice dialing used in a home gateway system in accordance with one embodiment of the invention. The process starts, step 350, by receiving an - 21 -

off-hook signal at step 352. Next, a voice command is received by the home gateway system at step 354. When the voice command of step 354 is a call request, a voiced name is received at step 356. A speech recognition process is performed on the voiced name and the recognized name is matched with an associated telephone number at step 358. At step 360 the home gateway system initiates a telephone call over a wireless local loop to the associated telephone number, which ends the process at step 362. In another embodiment the voiced command is a voice mail request. In this case the home gateway system will play a plurality of voice mail options to the user. The user can then voice a desired choice. In this way the voice mail can be operated by voice commands entirely instead of requiring keypad entries.

In another embodiment the voiced command is an email request. In this case the voice processing system converts the titles of each of the emails in a user's mail box from text to an audio signal. Then the titles are announced to the user. The user then announces his voiced selection. The voice processing system then converts the body of the email to an audio signal and plays the email to the user. This allows the user to interact with his email in at a purely vocal level. In another embodiment the home gateway system first initiates a communication session over the wireless local loop to an email provider. The user's emails (plurality of emails) are then downloaded to the home gateway system. - 22 -

In yet another embodiment the voice command is a request to forward a user's calls to a predetermined telephone number (predetermined forwarded telephone number). In this case the home gateway system requests a user voice a code. The home gateway system then performs a speaker verification on the code to verify the user's identity. When the user's identity is verified, the user is allowed to state a voiced command that forwards his call to a predetermined number. This embodiment allows a user to forward his calls using only voiced commands and verifies the user's identity for security.

In another embodiment, the home gateway system is used for conference calls. A first telephone call is established, then a conference call command is given. The command can be a flash hook, a voice command or a touch pad code on the telephone for instance. Next, a second telephone call is connected through a voice bridge. Then the first telephone call is connected through the voice bridge.

FIG. 18 is a flow chart of a method of operating a home gateway system in accordance with one embodiment of the invention. The method starts, step 380, by receiving a voiced command at step 382. Next it is determined if the voiced command is a call request at step 384. When the voiced command is the call request, a voiced name is received at step386. The voiced name is recognized by a speech recognition system and converted to an associated telephone number at step 388. A call is then placed to the associated telephone number over the wireless local loop (WLL) connection at step 390. - 23 -

When the voiced command is not a call request, a speaker verification routine is performed at step 392. When the user is not verified, the user is denied access to the home gateway system's features and the process ends, step 394. In another embodiment, the user is asked to input a PIN (Personal

Identification Number) when the system cannot verify their voice. When the user is verified, the user selects between the voice mail system, the email system and a forwarding request. When the user selects a forwarding request at step 396, the system receives a voiced command directing that the user's call be directed to a particular number at step 398.
