SS7 Signalling Protocol – Alcatel Unleashed

Systems and method for transporting multiple protocol formats in a lightwave communication network. Methods, systems, and computer program alcateel for organizing, managing, and selectively distributing routing information in a signaling message routing node. Organizing, managing, and selectively distributing routing information in a signaling message routing node.

SS7 user parts accesses message transfer part layer 3 via a service access point SAP It may be seen that certain SS7 link sets may become points of congestion in the SS7 network New services, such as local number portability, require a per-call query and response with a network database. Within the virtual path the facility is allocated into multiple virtual channels. The high speed signaling network, as set forth in claim 1, wherein the plurality of advanced intelligent network nodes comprise a service control point.

Message transfer alcateel 62 contains the necessary alcateel to s7s reliable transmission of functional signaling messages with maximum network availability. This is different from network topologies contemplated by other entities, such as Bellcore. Message transfer part 62 of SS7 includes three levels: One of the primary characteristics of broadband SS7 messages is the longer message size bytes versus bytes.

What is claimed is: SS7 platform manager configures the system from configuration fileswhich are read upon start-up of broadband SS7 platform 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 the physical location aalcatel the termination point of the signaling path.

A message transfer part layer 3 API library may be provided for applications who wish to directly access the message transfer part service primitives. Connection identification in transmission system of wireless telecommunication network over ATM protocol stack.

The method, as set forth in claim 10, further comprising the step of converting electrical circuit-based SS7 signaling data to optical packet-based asynchronous transfer ss77 signaling data. A plurality of customer premises equipment 38 are coupled to service switching points Methods and systems for providing database node access control functionality in a communications network routing node.

Overload protection for on-demand access to the internet that redirects calls from overloaded internet service provider ISP to alternate internet access provider. Data structure embodied in a computer readable medium for communicating signaling system seven SS7 user part messages between SS7 nodes.

The preferred embodiments of the present invention are illustrated in FIGS. User parts 64 provide criteria for application and alcatrl management. Distributed processing architechture for control of broadband and narrowband communications networks.

Further, any link within a link set may be dynamically loaded alctel 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.

More particularly, the invention is related to a system and method for transporting SS7 signaling over broadband asynchronous transfer mode links. 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. The SS7 platform manager provides layer management to all the components within the architecture via a layer management messaging protocol. Method and apparatus for integrated services digital network user part ISUP signaling loopback.

The high speed signaling network, as set forth in claim 1, wherein the plurality of high speed links comprise asynchronous transfer mode multi-channel transmission facilities.

Message transfer part layer 3 relies on the services of data link and physical layer for delivery of all messages. As telecommunication networks approach the next century, the ever increasing demand for new services and applications require a rapid expansion of the intelligent signaling and switching networks. Message transfer part layer 1 80 includes an interface to V. This invention is related in general to the field of telecommunications systems.

Message processing begins in message alcatsl part layer 3 Arrangements for switching multiple packet types combined in a single packet stream. In this manner, signal transfer point supports signaling for both circuit-based and packet-based connectivities.

Message transfer part layer 3 also uses primitives to communicate with SS7 user partsi. These new services are likely to drive current data links to full capacity and introduce additional call set-up delays using the lower speed data links used in today’s network. The ISDN user part is a protocol for circuit related messages and is used to set up and tear down all circuits used for data or voice calls in the public switched telephone network.

The qlcatel, as set forth in claim 14, wherein the circuit based SS7 signaling data is in electrical signals and the packet based asynchronous transfer mode packets are in electrical signals. Methods, systems, and computer readable media for inter-message processor status sharing. Method and system for mapping virtual connections to asymmetric digital subscriber line latency paths.

Method for managing signal network including a mixed message transfer part signal point.
