Abstract: A method and apparatus are provided for extracting and reporting communication associated information of communications between a subject and an associate. This is achieved by populating an application identifier in the Network Layer 3, which the access networks examine in order to route the packets appropriately, and, thereby, allowing the access networks to isolate and extract the communication associated information. The access networks extract the call associated information and report the same to the Law Enforcement Agencies. Delivery to the LEAs of communication associated information may also be optimized.

Abstract: A low-cost data communication system and method using modems to provide high speed multi-class services to subscribers is disclosed. In the present invention, an n-bit orthogonal modulating code is uniquely partitioned into several subsets whereas each subset is assigned to a particular class of services. When data streams from different classes of services go through an encoding modem equipped with the partitioned orthogonal codes, they can be split based on their classes, encoded, modulated through a multilevel phase modulation simultaneously. Thereafter, since the encoded streams are orthogonal to each other, they can be combined as a composite modulated outgoing data stream and transmitted through a wired communication channel such as a cable or optical fiber channel. At a receiving end, a decoding modem can receive the encoding scheme from the encoding modem, and appropriately decode the transmitted information.

Abstract: A system and method is disclosed for providing multiple classes of communication services on a high-speed, high capacity communication platform over Wave Division Multiplexing (WDM) networks. A predetermined set of light channels of a WDM network is partitioned into one or more sub groups based on their wavelengths, each sub group is assigned for providing exclusively one communication service such as video, audio or data communication services. Each light channel is modulated by a predetermined set of orthogonal codes so that neighboring channel interferences can be minimized. Further, the predetermined set of orthogonal codes can be further divided into an even group and an odd group. These two groups of codes are assigned to two immediate neighboring light channels.

Abstract: A system and method is disclosed for providing high-speed, high capacity data communication over a Wave Division Multiplexing (WDM) network with an efficient re-routing capability. When all light channels between two nodes in the network are loaded with transmission jobs, a transmission traffic congestion is created. In order to avoid or alleviate the congestion, a new alternative route is needed. An alternative route is selected to direct the traffic away from the congested route, and further expand the channel capacity of the alternative route by encoding the light channels in the alternative route with orthogonal codes.

Abstract: A number of user IDs are assigned to each wireless device. The number of user IDs required is based on the type of information transmitted (e.g., video, voice, or data). The user ID's generate the orthogonal Walsh codes used to cover a data signal to be transmitted. Each Walsh code is 2n-bits in length and the memory size is 2n×2n where n is the number of bits in the Walsh code. Each unique user ID addresses a memory to generate a unique Walsh code corresponding only to that user ID. The orthogonal codes output from the memory cover the information to be transmitted. This results in the transmitted signal being orthogonal to other users and also orthogonal within the transmitting user's own signal bursts.

Abstract: A method and apparatus for obtaining real-time call by call feedback from customers is to the perceived quality of network services may be accomplished after communication via network connection between a calling party and at least one called party is completed. Upon completion, the network retains for a predetermined period of time at least a portion of the network connection to one of the parties involved in the communication. During this predetermined period of time the party provides feedback as to his or her perception of the quality of various aspects of the call. The feedback is received within the predetermined period of time, the network compiles the data which can be then used to interpret the network service quality, diagnostic information as to catastrophic failures as well as mild failures, overall service, perceived quality of new services and features, and quality of internetworking.

Abstract: A method and apparatus for obtaining real-time, call by call, feedback from customers as to their perceived quality of network services may be accomplished after a communication, via a network connection between a calling party and at least one called party, is completed. Upon completion, the network retains, for a predetermined period of time, at least a portion of the network connection to one of the parties involved in the communication. During this predetermined period of time, the party provides feedback in the form of a sequence of numbers entered which identify his or her perception of the quality of various aspects of the call. If the feedback is received within the predetermined period of time, the network compiles the data which can then be used to interpret the opinion of many individuals as to network service quality, information as to catastrophic failures as well as mild failures, overall service, the perceived quality of new services and features, and quality of inter-networking.
