International Classification:

H04L 29/00

US Classification:

726 15, 726 14, 713150, 713153, 379900, 379901, 370351

Abstract:

The presently disclosed architecture enables a service provider to support public voice VPN services over an IP VPN network. The architecture utilizes a customer VPN, a designated gateway for the customer VPN, an IP VPN transport network, and a Call Control Element/router Complex which uses IP technology to map between the IP VPN and the voice VPN. With such an arrangement, the customer VPN is extended to the gatekeeper of the Call Control Element/router Complex, thereby enabling the provision of voice VPN services over an IP network.

International Classification:

G06F 11/00

US Classification:

714 37

Abstract:

A method, computer readable medium and apparatus for performing session establishment management. For example, the method detects an evolved packet system establishment success rate that is measured over a predefined period of time falling below a predefined threshold, and performs, via a rule management server, an analysis on a bearer portion. The method then associates, via the rule management server, a root cause that contributed to the evolved packet system establishment success rate falling below the predefined threshold.

International Classification:

H04W 28/16

US Classification:

370252

Abstract:

A method, computer readable medium and apparatus for performing mapping management are disclosed. For example, the method monitors network performance measurements of long term evolution mobility elements, monitors a class type and a bandwidth type of long term evolution interfaces, determines if an impairment state is detected based upon the monitoring network performance measurements and the monitoring the class type and the bandwidth type, determines if the impairment state is due to a class of service and a quality of service mismatch and reconfigures the quality of service if the impairment state is due to the class of service and the quality of service mismatch.

International Classification:

H04W 24/00

US Classification:

455424

Abstract:

A method and apparatus for enabling a wireless communication service provider to remotely provide wireless network service outage and/or degradation detection, isolation, and restoration relating to a base station are disclosed. For example, the method detects a wireless service problem, and isolates the wireless service problem to a base station of a plurality of base stations of the wireless communication network, wherein the wireless service problem comprises a wireless service degradation. The method then performs a recovery task remotely on the base station to address the wireless service degradation.

Assignee:

AT&T Corp - Middletown NJ

International Classification:

H04J 316
H04L 1228

US Classification:

370468

Abstract:

A communications system is provided which supports asynchronous transfer mode (ATM) communications. An ATM multiplexer is located at a customer's premises and connected to customer premises voice and data equipment. A central office ATM multiplexer is connected to various different networks in the existing network infrastructure. The central office ATM multiplexer is preferably connected to networks such as a low-speed packet-switched network, a public circuit-switched network, a private line network, and a high-speed packet-switched network. The ATM multiplexer located at the customer premises preferably supports dynamic bandwidth allocation. Additional features provided by the communications system include the ability to provide different voice encoding schemes for different users based on calling party or called party information.

International Classification:

H04M 1500

US Classification:

379114

Abstract:

Prior to completing a telephone call, a database is accessed within a telecommunications network to determine whether the call should be completed. The billing number to which the call is to be charged is compared to a customer record assigned to the billing number and stored in the database. The customer record is checked against a treatment category code which combines geographic call restrictions and thresholding. A call may be identified as potentially fraudulent and blocked if the customer record associated with the billing number indicates that the account is in arrears. In addition, at predetermined intervals during the progress of the call and at the end of each allowed call to be charged to that billing number, the time and/or cost of each call is estimated and added to the total stored in a user-defined threshold counter in the database. When the total stored in the counter exceeds a predetermined threshold limit, a potentially fraudulent call is identified. In this manner, call authorization is performed on a per call basis to prevent fraudulent telephone calls.
