Abstract:
A method of performing automatic callback notifier on reversed missed calls through network based enabler helps a caller to reach a callee by making reference to the presence status and subscribed to the callback service (115) provided by the network service providers. This method extends the functionality of existing device with a feature that prompts users to auto callback the callee who cannot be reached previously but is currently becoming available. This feature works by determining the presence status of the callee (215). Whenever the callee turns his status presence from "Not available" to "Available", the caller device will be acknowledged. This allows the caller device to automatically prompt the caller to proceed calling back the same callee (225).
Abstract:
A method (100) for real time seamless Internet Protocol (IP) multicast handoff from a network interface of a current network to a network interface of a new network that is independent of a mobility protocol implemented on the current network and the new network. The method (100) comprises activating the network interface of the new network (102), determining a delay duration for seamless Internet Protocol (IP) multicast handoff (104), receiving a plurality of Internet Protocol (IP) packets on the network interface of the new network (106) and de-activating the network interface of the current network upon expiration of the delay duration (108).
Abstract:
A centralized VoIP network system (10) comprises a plurality of endpoints (12a-12f) and a SIP server (11) coupled to said endpoints (12a-12f) in said network (10), said server (11) operable to determine the codec bitrate from the network bandwidth availability based on the predetermined threshold values.
Abstract:
A resource reservation method in a network, where the allocation of network bandwidth to each application connected to the network is determined by the end user is provided herewith.
