Abstract:
A method and apparatus for dynamic routing of wireless communications. More particularly, wireless communications are dynamically routed by marking, by a softswitch, every endpoint participating in a call and as the entry for a marked endpoint is updated a message is generated and sent to the softswitch. Upon receiving such a message, the softswitch re-computes the necessary new resources for maintaining the call and (i) instructs such new resources to negotiate media transfer, (ii) after receiving an acknowledgement from the new resources, transmits appropriate call initiation messages to such resources; and (iii) transmits call release messages to the prior, i.e., old, resources supporting the call. Advantageously, selection of the requisite resources to participate in a particular is driven by the knowledge of the communications network topology. As such, resources are selected which are topologically closer to the endpoint thereby increasing the efficiency of the network resources on a network-wide basis.
Abstract:
A method and apparatus for protecting against network damage in next generation communications networks. More particularly, network safety is achieved using semantic restriction of higher level call processing protocol primitives coupled with dynamically programming the various network routing elements to enforce both connection control and rate control.

Abstract:
An IP facsimile technique establishes a real-time IP connection for facsimile transmissions without the use of dedicated facsimile servers. A receiving facsimile device converts a given destination address, e.g., a electronic mail address and/or a telephone number, into a particular IP address associated with a sending facsimile device and utilizing the IP address establishes a direct IP connection between the sending and receiving locations for transmitting the facsimile message. Advantageously, the IP facsimile communication is made without requiring intermediate message conversions, i.e., hops, and does not require a dedicated facsimile server located in close proximity to the receiving destination.
