ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a system for providing transparent access to different types of communication networks that may be incompatible with each other and some of which may be incompatible with the equipment used by the calling party or the called party, least cost routing in such a system, maintaining quality of communication in such a system, prioritizing the routing of such communications, evaluating different communication access locations to determine where to send a communication, synchronizing communications, blocking incoming communications while waiting for the synchronizing to be completed, and minimizing the cost of communications using such a system. This system also monitors and records the services used on each of the unrelated service providers. This information is then utilized for billing purposes and for paying the service providers.
BACKGROUND OF THE INVENTION
Presently when communication services are offered on a global basis, communications are established through the equipment of a plurality of service providers located in various countries. This communication is dominated by large carriers which have formed the global network through reciprocal agreements. Smaller competing carriers, who may offer the same service at lower prices, currently do not have reciprocal agreements between them.
The invention provides these smaller competing carriers with access to each other without the use of the large carriers. Such access provides the calling party (e.g., a subscriber of the smaller competing carrier) with the option of obtaining optimum service at lower prices while ensuring that the appropriate service providers get paid. The calling party can now have cheaper access to different types of telecommunication networks that the party may not have access to under the current large carrier system. It may be cheaper or preferred for the calling party to use smaller carriers to communicate with another location by routing the communication over a digital data network rather than an analog voice network, or by routing the communication over a paging network rather than a cellular network or a combination of networks.
SUMMARY OF THE INVENTION
One objective of the invention is to provide communication between otherwise incompatible communication networks in a manner that is transparent to the calling party (that is, the subscriber of the service initiating the communication), while assuring that each service provider that renders service in routing that communication gets paid. Preferably, the communication is routed based on the results from an evaluation of all available communication networks even though the calling party may have direct access to only one type of communication network.
In accordance with the invention, control information in the form of an inquiry of the availability status of the party to be called may be sent through different networks by routing it through a control location of the inventive system that converts it into a compatible form. For instance, the called party may be using one type of network, such as a data network having E-mail, while the calling party is using another, such as a cellular network.
With a conventional data network, sending an E-mail message to an address on the data network does not indicate the availability of a party on a cellular network to communicate. In accordance with one embodiment of the invention, however, the control location of the inventive system is connected with both the data network and the cellular network to convert the control information associated with E-mail into a form compatible on the cellular network for making an inquiry and then transmits the inquiry over the cellular network.
The inventive system may have external or internal software and hardware that intercepts the normal transmission to route it appropriately. The system effects further routing, which may include converting between different forms of communication networks, compressing voice into data packets or decompressing data packets into voice, coding and decoding transmissions for security reasons, and multiplexing communications over the same lines. The system records the various routing transactions involved in the communication and calculates the billing of the transactions in a manner that is transparent to the calling party.
Another objective of the invention is to interrogate the called party number's communication availability prior to conferencing the calling party and called party. The inventive system may have a control location that receives both a calling party and a called party access number or identification. After receiving these access numbers, the system initiates an inquiry to the called party from the control location and waits for a status signal as to the called party location's availability to take incoming calls. If the status signal indicates an available status, a first communication is initiated to the called party access number from the control location and a second communication is initiated to the calling party access number from the control location. Thereafter, the first and second communications are bridged using the same or different networks.
In addition to interrogating the called party's availability status, the control location determines where to route the call by examining factors such as transmission cost, the appropriate network for the desired transmission, the service provider that provides this kind of network and the plurality of available called party locations that service the called party access number. The control location also considers communication networks that are available to the called party locations and the identity of service providers who provide those communication networks across the various called party locations. After receiving the calling party and called party access numbers, the control location performs an inquiry as to which service provider and which network can route the transmission.
In addition to technological considerations, the control location also studies the various cost to perform the desired transmission and records such information for both monitoring and billing purposes. An authorizer uses such information to monitor all incoming and outgoing transactions between the network service providers and provide clearance insuring payment and settlement of all transaction for each of these operators.
In routing communications, the control location takes into consideration customer defined preference criteria relating to preferences for particular types of communication network, transmission quality, cost, security, and priority of transmission. For example, if the quality of a transmission is not acceptable, the transmissions may be rerouted to any other available network that can transmit with better quality, thereby ensuring that the quality of the transmission satisfies the customer's preference criteria for transmission quality. The calling party access number itself may include a message or protocol containing preference criteria selections.
Another objective of the invention involves synchronizing the completion of callback from the control location to the calling party and called party legs of communication. The synchronization involves the calculation of the waiting time that is necessary before the control location commences each callback. The waiting time may be fixed or read from memory off a data base located at the control location. This synchronization may result in completion of both communications simultaneously or with minimal delay, i.e., a significantly shorter delay than without the synchronization. Such synchronization results in more efficient use of the network at a lower cost.
While the control location is waiting to initiate completion of one of the callback legs of communication, an incoming communication may block the completion of that one leg and thereby interrupt the synchronization from taking place. The blocking period may be for a fixed time period or may be based o
