SS7 Signalling Protocol – Alcatel Unleashed

Methods, systems, and computer readable media for managing the flow of signaling traffic entering a signaling system 7 SS7 based network. The narrowband signaling link configuration is provided through SS7 message transfer part layers 1 and 2. User parts 64 provide criteria for application and service management. Service switching points 22 are part of the public switched telephone network and are coupled to the customer premises equipment CPE 28 of telephone service subscribers.

Methods and systems for communicating SS7 messages over packet-based network using transport adapter layer interface TALI. Hu e lamo, J. Connection identification in transmission system of wireless telecommunication network over ATM protocol stack. Within the virtual path the facility is allocated into multiple virtual channels.

The high speed signaling network, as set forth in claim 8, wherein the plurality of high speed links comprise electrical-based asynchronous transfer mode transmission facilities carrying SS7 signaling data links. Overload protection for on-demand access to the internet that redirects calls s7 overloaded internet service provider ISP to alternate internet access provider.

In the intelligent network IN or advanced intelligent network AINSignaling System Number 7 SS7 is the signaling protocol for the telecommunications network which is transmitted over 56 or 64 Kbps data links. Public telephone network, intelligent network, and internet protocol network services interworking.

To support the SS7 signaling over an asynchronous transfer mode link the message transfer part layer 3 interfaces with a SAAL signaling asynchronous transfer mode adaptation layer A user interface may alcatrl be provided alcayel SS7 platform manager for interactive access to broadband SS7 platform Broadband SS7 platform provides narrowband signaling links xs7 integrating message transfer part layer 3 with an message transfer part layer 2 and 1 and ultimately a physical link supporting V.

The SS7 platform manager provides layer management to all the components within the architecture via a layer management messaging protocol.

Further, any link within a link set may be dynamically loaded with the total capacity of the facility bandwidth to any level of occupancy of the virtual channel so long as the total facility bandwidth has not been exceeded by the total usage of all available channels. Methods and systems for communicating SS7 messages over packet-based network using transport adapter layer interface.

It may be seen that certain SS7 link sets may become points of congestion in the SS7 network SS7 user parts accesses message transfer part layer 3 via a service access point SAP The virtual path connection is defined based on the interpretation of the higher layer SS7 message transfer protocol MTP-3 that includes a destination point code which identifies sx7 physical location of the termination point of the signaling path.

Methods and systems for providing database node access control functionality in a communications network routing wlcatel. A high speed signaling network includes a high speed transport virtual circuit network, and a plurality of advanced intelligent network nodes coupled to the high speed transport virtual circuit network via a plurality of high speed links transporting signaling data.

Arrangements for switching multiple packet types combined in alatel single packet alcatwl. Message transfer part layer 3 relies on the services of data link and physical layer for delivery of all messages. However, message transfer part layer alfatel accesses the asynchronous transfer mode layer 2 functionality with alcate same set of primitives as those used to interface with message transfer part layer 2.

The method, as set forth in alccatel 10, alcxtel comprising the step of converting electrical circuit-based SS7 signaling data to optical packet-based asynchronous transfer mode signaling data. Signal transfer points are coupled to network by optical link sets which may transport asynchronous transfer mode OC-3 or STM-1 format signals.
