Patent Application
20080123836
This application relates generally to hosting telephony services. More specifically, the application relates to a party independent of a telephone network operator providing telephony services.
Traditionally, telephony operators provide telephony services by placing components within their networks. Some functionality can be owned by a subscriber of a fixed line network (e.g., Integrated Services Digital Network, Plain Old Telephone System, or another packet switched network). For example, a business can purchase a private branch exchange (PBX). The PBX interfaces with the fixed line network and also to each of the dedicated fixed lines within the business.
Some companies do not have the resources to purchase their own PBX equipment. As such, a PBX hosting service charges a fee for interfacing the companies fixed lines to a PBX that is owned by the hosting service. One example of a company providing such services is VIRTUAL PBX of San Jose, Calif.
To provide a mobile phone an extension using a traditional PBX, “tromboning” of a call through the PBX is required. Tromboning refers to transferring a call to a mobile phone via a PBX where the resulting call occupies one inbound phone line and one outbound phone line for the duration of the call. Tromboning adds extra cost for the enterprises using it.
In one aspect, the application features a method of providing telephony services as a hosted online service for a subscription fee.
In another aspect, the application features systems and methods for hosting telephony services.
In still another aspect, the application features systems and methods for routing a call within an enterprise.
In one aspect, the invention features a method of providing telephony services to an enterprise. The method includes executing an application on a computing device external a mobile telephone network and interfacing the computing device to the mobile telephone network. The application provides PBX services to the enterprise. The method also includes generating, by the computing device external to the mobile network, a signal to provide at least a portion of a the PBX service on the mobile telephone network and transmitting the signal to a telephonic device connected to the mobile telephone network.
In one embodiment, the computing deice interfaces to a fixed line network. In another embodiment, the computing device interfaces to an IP network.
In one embodiment, generating a signal includes generating a signal to instruct a telephonic device to connect to the computing device via the mobile network.
Further features and advantages of the present invention will be apparent from the following description of preferred embodiments and from the claims.

With reference to
The enterprise operator 104 can have a computing device 105 executing software that provides at least some of the below-described functionality. A human operator 107 interacts with the computing device 105 to, for example, issue commands from the computing device 105 to the data center 102, which in turn issues commands to the mobile network 108, to transfer an incoming fixed line call to a mobile telephone associated with the enterprise subscribing for telephony services. As used herein, telephony services include, but are not limited to, auto attendant (IVR), switchboard, hunting groups, ring groups, personal assistant, short number dialing, PBX services, barring, ACD, conferencing, and others.
The network 114 that connects the enterprise operator 104 with the data center 102 can be a local-area network (LAN), a metropolitan-area network (MAN), or a wide area network (WAN) such as the Internet or the World Wide Web. The enterprise operator 104 connects to the network 140 via communications link using any one of a variety of connections including, but not limited to, standard telephone lines, LAN or WAN links (e.g., T1, T3, 56 kb, X.25), broadband connections (ISDN, Frame Relay, ATM), and wireless connections. The connections can be established using a variety of communication protocols (e.g., TCP/IP, IPX, SPX, NetBIOS, and direct asynchronous connections).
In other embodiments, the enterprise operator 104 connects to the data center 102 through a second network (not shown) using another communication link that connects network 114 to the second network. The protocols used to communicate through the communications link can include any variety of protocols used for long haul or short transmission. For example, TCP/IP, IPX, SPX, NetBIOS, NetBEUI, SONET and SDH protocols or any type and form of transport control protocol may also be used, such as a modified transport control protocol, for example a Transaction TCP (T/TCP), TCP with selection acknowledgements (TCPSACK), TCP with large windows (TCP-LW), a congestion prediction protocol such as the TCP-Vegas protocol, and a TCP spoofing protocol. In other embodiments, any type and form of user datagram protocol (UDP), such as UDP over IP, may be used. The combination of the networks can be conceptually thought of as the Internet. As used herein, Internet refers to the electronic communications network that connects computer networks and organizational computer facilities around the world.
The packet switched network 110 communicates with the data center 102. As used herein a packet switched network refers to a data communications network where information (e.g., voice and data) is divided into packets and delivered to their destination separately and possibly via different paths. Some packet switched networks provide voice-over-IP (VOIP) functionality. The data center 102 can provide telephone services to enterprise subscribers having telephone devices terminated on the packet switched network 110. As used herein, telephone devices refers telephones, fax machines, computers, IP phones, soft phones, video phones, mobile phones, wlan phones, or other devices capable of transmitting and receiving audible information.
The circuit switched network 112 also communicates with the data center 102. As used herein circuit switched refers to routing traffic between an originator and a destination through switching centers, from local users or from other switching centers, whereby a continuous electrical circuit is established and maintained between the calling and called stations until it is released by one of those stations. For example, the switched circuit network 112 can be the public switched telephone network (PSTN). The data center 102 can provide telephone services to enterprise subscribers having telephone devices terminated on the circuit switched network 112.
The mobile network 108 communicates with the data center 102. As used herein, mobile network refers to facilities operated by a telephony carrier for the purposes of providing public mobile telecommunications services. Various embodiments, of the mobile network 108 are described in more detail below with reference to
The data center 102, in one embodiment, includes, a web server 116, a control device 118, and a network operation center (NOC) 120. Although shown as separate components, the web server 116, the control device 118, and the NOC 120 can be combined in many ways and supported by a one or more computing devices. The data center 102 is located external to at least one of the mobile network 108, the packet switched network 110, and the circuit switched network 112. That is, the data center 102 is not under control of an operator of either of the mobile network 108, the packet switched network 110, and the circuit switched network 112. The data center 102 provides an ingress point to one or more of the mobile network 108, the packet switched network 110, and the circuit switched network 112. Also, the data center 103 can serve as a termination point for a fixed line telephone number associated with an enterprise subscribing with the operator of the data center 102 for telephony services. A single data center 102 can support one or more subscribing enterprises. In some embodiments, multiple data centers 102 are present.
As an operational summary, the data center 102 interfaces to one or more of the mobile network 108, the packet switched network 110, and the circuit switched network 112 to provide fixed line call pricing to customers of the enterprise even though the enterprise uses mobile phones. The data center 102 can provide telephone services to enterprise subscribers having telephone devices terminated on a packet switched network or a mobile network 108. In one embodiment, an enterprise subscriber contracts for telephone services. In turn, a fixed line telephone number associated with enterprise subscriber is terminated at the data center 102.
This fixed line main number can be the initial entry point for an enterprise. In some instances, the fixed line main number is well known by customers and potential customers of the enterprise. For example, 1-800-FLOWERS is a well known fixed line main number. In some regions of the world, it is less expensive to call a fixed line number than a mobile telephone number. It may also be less expensive for the enterprise to receive calls at a fixed line number instead of mobile telephone numbers associated with respective principals of the enterprise. Continuing with the 1-800-FLOWERS example, if that enterprise decided to replace their existing PBX services with telephony services described herein the enterprise would likely want to keep their 1-800-FLOWERS fixed line number. By porting the known fixed line number to the data center 102, the enterprise can provide PBX and other telephony services to mobile telephones associated with the enterprise without relinquishing their known fixed line numbers. Another benefit is that customers calling 1-800-FLOWERS are not be charged at a fixed-line-to-mobile rate, instead they are charged at fixed lined-to-fixed-line rate. Further details of these benefits are described below in more detail.

The commands and data include, but are not limited to, instructions to transfer an incoming call to enterprise employee, place a call on hold, data related to the call status (e.g., elapsed time, caller id, call control commands, messaging commands, configuration commands, status about calls, handset status, queues, conferences, and others
The data center 102 terminates a fixed line main number of the enterprise subscribing for PBX services. In one embodiment, the fixed line main number is a toll free number. In other embodiments, the fixed line main number is a local number.
As an operational overview, a customer calls the enterprises main number. It is a fixed line number and customer only incurs a fixed line charge (which could be zero depending on their operators price plans). The customer is connected to the data center 102 where an IVR system welcomes the customer and for calls directed to the enterprise operator 104 places the customers call on hold playing music.
Next, the data center 102 locates an available enterprise operator 104 and initiates a call setup between the phone of the enterprise operator 104 and the data center 102 center. In response, the mobile network 108 sets up a call leg to the enterprise operator 104. As a result, the enterprise operator 104, and therefore the enterprise, incur a fixed line charge. Once the enterprise operator 104 answers the incoming call, the enterprise operator 104 audio stream is connected to the waiting customer's audio stream and the enterprise operator 104 begins servicing the waiting customer.
The data center 102, also sends information about the call (e.g., caller ID) to a display screen of the enterprise operator 104. If the enterprise operator 104 chooses to transfer the customer call to an employee 302 of the enterprise, the transfer is accomplished within the mobile network 308. If the employee 302 is using a mobile phone 303 within the same network of the enterprise's price plan there is typically no extra charge for transferring the call.
