Patent number: 7813490Abstract: A ring-back tone generator system receives an inbound call connection request forwarded from a phone switch (such as an MSC) that receives the inbound call connection request from a caller phone attempting to connect to a target phone (e.g., a subscriber). The ring-back tone generator system initiates generation of a first call connection on which to provide the customized ring-back tone (and/or custom video image data) to the caller phone. The ring-back tone generator system also transmits, based on receiving the inbound call connection request, an outbound call connection request to the phone switch (such as the MSC) to establish a second call connection through the phone switch to the target phone. Consequently, an MSC that normally handles such call processing now relies on the ring-back tone generator system to handle call processing and provide a custom ring-back tone service.Type: GrantFiled: November 5, 2004Date of Patent: October 12, 2010Assignee: NMS Communications Corp.Inventors: Jeffrey M. DeMent, Christophe Gerard

Patent number: 7558861Abstract: Users of network based software applications typically interact with an application via a command line interface or a menu interface. Conventional voice-driven communication threads rely on a dedicated communication line (connection) to maintain a session context, or state, between a user and an application for the duration of a session. Such state information enables the application to reference a session context for the session duration, and employ the session context to maintain a state from previous atomic messages sent and received between the device and the application. By maintaining and referencing a session context indicative of previous messages, an application identifies an atomic message as corresponding to a particular session context, and employs the session context to process the message within the context, or environment, defined by the previous messages in the session.Type: GrantFiled: October 23, 2003Date of Patent: July 7, 2009Assignee: NMS Communications Corp.Inventors: Imran H. Qidwai, John J. Ciarlante, James B. Holt, II

Patent number: 7072296Abstract: Wireless network demands continually increase as wireless service providers pursue additional service capabilities. In a cellular communication system, leased lines between remote cell sites and the corresponding Mobile Switching Offices (MSOs) remain a major operating cost. Bandwidth reduction by identification and elimination of payload data and control information which need not be fully replicated because it can be deduced from information accessible or previously transmitted allows fewer lines to support the same bandwidth. A wireless access gateway is operable to aggregate such redundant and regenerable data on a backhaul link between a wireless cell site and the corresponding mobile switching office (MSO) to provide low-latency, type specific lossless bandwidth reduction. The wireless access gateway identifies regenerable information and eliminates portions of the data which the device need not transmit because the data is redundant, or accessible or recreatable, at the receiving side.Type: GrantFiled: August 1, 2003Date of Patent: July 4, 2006Assignee: NMS Communications CorporationInventors: R.

Patent number: 7043538Abstract: Via a thin client, a first user communicates with a presence server and establishes a communication channel with a second user through the presence server. The communication channel supports instant messaging in which the first user communicates via use of a first communication protocol and the second user communicates via use of a second communication protocol. When the thin client temporarily disconnects from the presence server, the presence server maintains an active “open” session for the thin client even though the thin client is disconnected from the presence server. The thin client can reconnect to the presence server and re-establish communications over the open session, enabling the first user to again instant message the second user.Type: GrantFiled: July 2, 2001Date of Patent: May 9, 2006Assignee: NMS Communication CorporationInventors: David Guedalia, Gavriel Raanan, Lawrence Reisler

Patent number: 6925175Abstract: Apparatus and accompanying methods for use in a long-haul echo control device to automatically measure sufficient changes in path length and compensate a long-haul echo canceller for resulting variations in echo occurring over a path. The apparatus measures a round-trip path delay interval of, e.g., a predefined signaling tone(s) sent between international switching centers while establishing an outbound call connection over the path. Once the delay is measured, the apparatus sets echo delay of a corresponding long-haul echo canceller to accommodate that delay. For a multi-channel facility (e.g., T1 or E1), path delay is separately measured for each channel on that facility, and then the apparatus changes the echo delay to the same amount for the corresponding echo canceller associated with each and every channel on that facility.Type: GrantFiled: September 27, 2002Date of Patent: August 2, 2005Assignee: NMS Communications CorporationInventor: Ronald H.

Publication number: 20030190040Abstract: Apparatus and accompanying methods for use in a long-haul echo control device to automatically measure sufficient changes in path length and compensate a long-haul echo canceller for resulting variations in echo occurring over those paths. Specifically, the inventive apparatus measures a round-trip path delay interval of, e.g., a predefined signalling tone(s) sent between international switching centers during the course of establishing an outbound call connection over that path. Once this delay interval is measured, the apparatus commensurately sets echo delay of a corresponding long-haul echo canceller to accommodate this path delay. For a multi-channel facility (e.g., T1 or E1), path delay is separately measured for each channel on that facility. Should the measured path delay sufficiently change for any one such channel, then the apparatus changes the echo delay to the same amount for the corresponding echo canceller associated with each and every channel on that facility.Type: ApplicationFiled: September 27, 2002Publication date: October 9, 2003Applicant: NMS Communications CorporationInventor: Ronald H.

Publication number: 20030185160Abstract: Apparatus for an echo canceller, and an accompanying method for use therein, for improving voice performance in handling mobile-to-mobile calls in a GSM environment, specifically with a base station controller (BSC) at each end of a call path where one BSC supports tandem free operation (TFO) and the other does not. Here, each canceller has a capability, through unique in-band messaging carried by robbed-bit signaling, to communicate information with its peer (distant) echo canceller across the call path so as to permit each canceller to coordinate its operation with the other, and particularly to enable a specific voice enhancement feature set optimal to a particular type of call, e.g., mobile-to-mobile, and without adversely affecting the TFO protocol.Type: ApplicationFiled: March 27, 2003Publication date: October 2, 2003Applicant: NMS Communications CorporationInventor: Ronald H.
