Abstract:
Wireless electronic devices such as cellular telephones may communicate with computing equipment such as servers over a network. Voice telephone calls may be routed over voice links in a voice network and data may be conveyed over data links in a data network. The voice network may be formed using the public switched telephone network. The data network may be formed using the Internet. Cellular base stations may form wireless links with the wireless devices. A server may store information on the current internet protocol address of a wireless device user. The user may place a voice telephone call to an organization. In response to receiving the voice telephone call, a server may automatically transmit information such as web pages or other data that includes interactive on-screen options to the wireless device using the current internet protocol address of the device.
Abstract:
An Advanced Intelligent Network architecture is used by a first telecommunications service provider having an operator services switch to provide enhanced call processing for operator services calls. The calls received at the operator services switch originate from a second telecommunications service provider, and the first telecommunications service provider provides custom services to the subscribers of the second telecommunication service provider. A call received at the operator services switch triggers the switch to query a control point for instructions, which in turn may query an external service parameter database. The control point instructs the switch to temporarily connect the caller to a peripheral resource providing a custom branding announcement to the caller and a menu of options from which the caller may select popular destinations. After provision of the custom branding announcement and menu, the call to the intelligent peripheral is released and the caller is routed to the appropriate service, which can be a directory assistance service.
Abstract:
A voice communication system, which is connected to a LAN to which communication terminals are connected and to a public network to which telephones are connected, is provided with a communication server between the LAN and public network having different protocols from each other. The communication server enables a voice communication between a telephone on the public network and a communication terminal connected to the LAN by performing processing similar to that for a voice communication between two communication terminals connected to the LAN. The communication server determines whether an address of the other party inputted by a user is a communication terminal address or a telephone number, and transmits a voice communication request to a communication terminal of the other party when the address is a communication terminal address. When the address is a telephone number, the user acquires the communication terminal address of the communication server, and transmits a voice communication request to the communication server. Thereafter, the voice communication processing is performed through the communication server.
Abstract:
A mechanism for providing a connection from an IP-based network to a circuit-switched network, such as a GSM network is disclosed. A temporary routing number for the circuit-switched network, such as an E.164 number, is delivered to a user terminal, and a circuit-switched call leg is established from the user terminal to the IP-based network using the routing number. Thereby, IMS-services are provided for end users which are located in the radio access network not having sufficient QoS required for voice over IP. In the example of a conference call service, a request for a conference call may forwarded via a data channel or data path to an application server which provides that conference call service. The application server then selects a conference routing number and returns the routing number to the conference host terminal via the data channel. Using the received conference routing number, the conference host terminal can then set up a circuit-switched connection as a call leg of the conference call.
Abstract:
A method is provided for detecting interactions between call-related and web-enabled features. In some embodiments, communication application components are configured to transmit an indication to a feature interaction detector every time a feature is invoked by the user. When the interaction detector receives an indication that a feature is being invoked, it compares the invoked feature against features that have previously been invoked (or executed) and determines whether the invoked feature interacts with any of the features that have been previously executed.
Abstract:
A network architecture in accordance with the present invention includes a communication network that supports one or more network-based Virtual Private Networks (VPNs). The communication network includes a plurality of boundary routers that are connected by access links to CPE edge routers belonging to the one or more VPNs. To prevent traffic from outside a customer's VPN (e.g., traffic from other VPNs or the Internet at large) from degrading the QoS provided to traffic from within the customer's VPN, the present invention gives precedence to intra-VPN traffic over extra-VPN traffic on each customer's access link through access link prioritization or access link capacity allocation, such that extra-VPN traffic cannot interfere with inter-VPN traffic. Granting precedence to intra-VPN traffic over extra-VPN traffic in this manner entails special configuration of network elements and protocols, including partitioning between intra-VPN and extra-VPN traffic on the physical access link using layer 2 multiplexing and the configuration of routing protocols to achieve logical traffic separation between intra-VPN traffic and extra-VPN traffic at the VPN boundary routers and CPE edge routers. By configuring the access networks, the VPN boundary routers and CPE edge routers, and the routing protocols of the edge and boundary routers in this manner, the high-level service of DoS attack prevention is achieved.
Abstract:
A VoIP gateway apparatus is used to provide an IP centrex service to accommodated devices. The VoIP gateway apparatus (1) assigns, to a call originated from an accommodated device (PBX 2), a telephone number for which the number of simultaneous call connections has not reached a simultaneous connection tolerance number, and sends the call to an IP centrex network (5) with the assigned telephone number used as a calling number. The VoIP gateway apparatus (1) includes a number-of-calls management part (105) and a SIP processing part (104). The number-of-calls management part (105) manages the number of the current simultaneous call connections for each of the telephone numbers as assigned to the apparatus. When a call is received from an accommodated device, a SIP processing part (104) selects, among the telephone numbers as assigned to the apparatus, a telephone number, for which the number of the current simultaneous call connections as managed by the number-of-calls management part (105) is smaller than the predetermined simultaneous connection tolerance number, and then transmits, to the IP centrex network (5), a SIP packet of a call control message to which the selected telephone number has been added as the calling number.

The fixed communications units may be public switched telephones (2, 3), PC phones (6, 7), PDA units, etc. The invention makes it possible to optimize the sound quality in dependence on which type of fixed communications unit coupled to the mobile unit, and which task is to be solved. In one embodiment, it is possible to lock the bandwidth, e.g. to the lowest bandwidth, irrespective of which fixed communications connection is used.
Abstract:
The invention relates to a method of routing a call made by a calling party to a fixed telephone number of a called party, said method comprising: —checking if the called party is a subscriber to a routing service; —if the called party is a first subscriber: checking if the first subscriber is located in a first area covered by one or more wireless access points; —checking if the calling party is a subscriber to said routing service; —if the calling party is a second subscriber: checking if the second subscriber is located in a second area covered by one or more further wireless access points; —routing said call to one or more mobile terminals associated with said fixed number via an IP network and one of said wireless access points in the case wherein said first subscriber is located in said first area or both said first subscriber and said second subscriber are located in their respective first and second areas, or otherwise routing said call to a predetermined alternative terminating point. A specific Service Control Point is arranged to store a list that comprises alternative terminating points for the calls to the fixed number.
Abstract:
In media communication by way of a packet-switching network and a circuit-switching network, a protocol conversion device for converting protocols between the packet-switching network and the circuit-switching network includes a call connection unit and a protocol converter. The call connection unit carries out call connection processes of media communication between terminals of the packet-switching network side and terminals of the circuit-switching network side. The protocol converter analyzes packets of speech received from the packet-switching network to specify the encoding bit rate of speech data in the speech packets. The protocol converter then specifies the multiplex table used in multiplexing frames on the circuit-switching network from the encoding bit rate. The protocol converter further generates frames by using the multiplex table that was specified to multiplex data in the payload of packets received from the packet-switching network and transmits to the circuit-switching network.
