Gateway for next-generation network, dynamic extending, and open interface technology

Abstract

Dynamic expandable Parlay / OSA gateway of open interface technique in use for next generation of network is composed of soft bus, configuration management unit, SCF unit, TCAP / non TCAP quasi protocol mapping unit, operation maintenance unit and network administer unit. Being as common communication channel for each unit / module, the soft bus can shield difference of isomerous application system and network system so as to make the gateway possible to be deployed in practical network environment. Executing register / cancel mechanism of modules, the control center-configuration management unit makes the gateway introduce new SCF module and protocol mapping module dynamically in plug and play mode or start up process instance of new module, also realize load balancing. When replacing protocol stack, the protocol-mapping unit is modified partially in protocol adaptation layer; and codes of SCF module does not need to be modified. Features are: good expansibility, and easy of application.

Description

technical field [0001] The present invention relates to a gateway for NGN (Next Generation Network), to be precise, relates to a dynamically expandable Parlay / OSA gateway with open interface technology, and belongs to the technical field of information processing devices in telecommunication networks Background technique [0002] In the first few decades of the birth of the telecommunication network, the main control hardware and software were concentrated in the switches. If a new service is to be provided, or even a slight modification to the service is required, all switches in the network must be changed. The price paid is very expensive. [0003] In the 1990s, the intelligent network standard of ITU-T proposed for the first time the idea of ​​separating service control and network control, defined four plane structures for top-down functional decomposition, and adopted the service independent building block SIB (Service Independent Building Block ) realizes software re...

AI Technical Summary

Problems solved by technology

At present, the existing Parlay / OSA gateways are provided by various network operators, because Parlay has not stipulated the resource interface with each underlying network, so the connection between Parlay / OSA gateways and each communication network can only be operated temporarily by network operators Set the internal communication protocol by yourself, such as using JAIN, INAP, SIP to map API to the low-level network
