The method, apparatus and system can improve efficiency and operability of deploying IP phone numbers for a large quantity of IP phone terminals.

A first data center includes a first virtual network that provides a communication service in cooperation with at least a part of a communication facility of a first communication operator and a first communication unit that is operable to communicate with a second data center. The second data center includes a second virtual network that provides a communication service in cooperation with at least a part of a communication facility of a second communication operator and a second communication unit that is operable to communicate with the first data center. The first communication unit is operable to transmit to the second communication unit, communication data to be transmitted from a first terminal connecting to the first virtual network via a communication facility of the first communication operator to a second terminal connecting via a communication facility of the second communication operator to the second virtual network.

A relay server 31 includes: a detection unit 31A that detects a failure of a subscriber server 21; and a relay unit 31B that relays call connection requests 51, 52, and 53 to another network in which corresponding subscribers may possibly be accommodated according to connection attempt network information indicating networks to attempt a call connection, when a failure of the subscriber server 21 is detected by the detection unit 31A.

A telecommunication network 30 for telecommunications between telecommunication end point devices 36,37,38, such as telephones or video phones, the telecommunication network 30 comprising a plurality of telecommunication device control systems 40 implemented by a computer system. Each telecommunication device control system 40 is shared by telecommunication end point devices 36,37,38 allocated to it and is configured to control communication connections involving telecommunications originating from telecommunication end point devices 36,37,38 allocated to it and other telecommunication end point devices. At least some functionality of the plurality of telecommunication device control systems 40 is shared by at least some parts of the computer system.

A method, system, apparatus, and/or device for rerouting a location-based phone call. The method, system, apparatus, and/or device may include a home cellular network and a location-based routing platform. The home cellular network may be configured to receive registration data indicating a cellular tower communicatively coupled with a cellular device, receive a location-based telephone call from the cellular device, and send the registration data to a location-based routing platform. The location-based routing platform may be configured to receive the registration data from the home cellular network, determine a location of the cellular device, and send a redirection request to the home cellular network for the home cellular network to redirect the location-based telephone call to a local phone system associated with the location of the cellular device, where the home cellular network is configured to redirect the location-based telephone call to the local phone system.

The present invention relates to a method for routing communications in a telecommunications network comprising a first telephony user device and a server system. The method includes at the first telephony user device: receiving instructions to initiate communications with a contact associated with an address; initiating communications via a channel within the telecommunications network to a local address for the server system; and transmitting information associated with the contact address to the server system via the telecommunications network. A communications action is performed in relation to the contact at the server system. Other methods, devices, systems and networks for routing communications are disclosed.

A system for exchanging GPS or other position data between wireless devices for purposes of group activities, child location monitoring, work group coordination, dispatching of employees etc. Cell phones and other wireless devices with GPS receivers have loaded therein a Buddy Watch application and a TalkControl application. The Buddy Watch application communicates with the GPS receiver and other wireless devices operated by buddies registered in the users phone as part of buddy groups or individually. GPS position data and historical GPS position data can be exchanged between cell phones of buddies and instant buddies such as tow truck drivers via a buddy watch server. Emergency monitoring services can be set up with notifications to programmable individuals in case an individual does not respond. Positions and tracks can be displayed. TalkControl simplifies and automates the process of joining talk groups for walkie talkie services such as that provided by Nextel.

Concepts and technologies provided herein can provide high-definition voice for fixed mobile convergence on mobile and wireline networks. A processor executing instructions can detect a call request associated with a called telephone number to setup a call session, where the call request is initiated from a calling device associated with an originating network. The processor can determine a call path for the call session from the originating network to a receiving network. The processor can create a fixed mobile convergence request to alert an electronic number mapping system of the call path for the call session from the originating network to the receiving network. The electronic number mapping system can provide a network presence map identifying a plurality of call receiving devices associated with the called telephone number that are available to participate in the call session via the receiving network.
