Embodiment Construction

[0036] The present invention will now be fully described with reference to Figures 1-23, in which like parts are designated by like reference numerals.

[0037] Figure 1a illustrates a block diagram of a telephone system 10 with PHS capability. A series of devices 14 such as telephones, PBX (Private Branch Exchange), modems and digital devices are connected to PSTN (Public Switched Telephone Network) 12 . In addition, a series of PHS base stations 16 are also connected to the PSTN 12 . A PHS mobile phone (or other device such as a digital modem) 18 communicates with other devices connected to the PSTN 12 through a base station 16 using wireless communication.

[0038] AIN (Advanced Intelligent Network) system 22 includes one or more STP (Signal Transfer Point) 24 connected to PSTN 12 . These STPs are connected to each other and to a plurality of SCP (Service Control Point) pairs 26 . Each SCP pair 26 includes two fully redundant SCPs 26a and 26b, as will be described in mor...

Abstract

AIN services include multiple SCP pairs, which can be expanded to meet increased demand. The expansion can occur without cessation in services by migrating records between SCP pairs while maintaining redundancy between the pairs. A centralized GTT maintains the GTTs distributed between multiple subsystems in the AIN system. Synchronization between mate SCPs within a pair occurs at high speed as the subscriber database is split into multiple files, each file having a separate synchronization process.

Description

technical field [0001] The invention belongs to the technical field of telecommunications. In particular, the present invention relates to methods and apparatus for providing a scalable redundant database. Background technique [0002] In recent years, wireless telecommunications have developed rapidly. One of the most common forms of wireless telecommunications is cellular telephony, however, other technologies such as the PHS (Personal Handyphone System), which is widely adopted in Japan, are expected to have a significant impact on other parts of the world in the coming years . [0003] PHS differs from cellular technology in that mobile devices such as telephones and modems communicate through "base stations" that typically have a cell distance range (radius) of around 100-500 meters, compared to 1500- About 5000 meters. Therefore, the distribution of base stations is much denser than in the case of cells. However, the output of PHS handsets can be much lower than t...
