- 1 . Operator Services System (OSS)
- In the early telephone systems, almost all services were provided by a single operator. Today, operator services are gradually being automated. The operator services system (OSS) described by Bell Operating Company includes both automated and non-automated operator services. These services are divided into two categories: the first category is called "help", which helps users complete the absorption and processing of special requests; the second category is called information, which is used to provide users with phone numbers, address information, and so on. OSS includes a tandem exchange system that can provide special operator services; OSS can receive calls from other LEC and IC attendant systems, end offices, and LEC tandem offices; the OSS database contains services for calling and information services Required information.
- 2 800 business
- The 800 business started in 1976 and was mainly used to provide free services to telephone users. During an 800 call, all calls must first be processed by the SSP (Service Switching Point); the SSP recognizes the 800 number, suspends normal call processing, forms an SS7 message, and finally sends the message via the STP (Signaling Transfer Point) Passed to the Service Control Point (SCP). SCP sends a query message to the SCP800 database. This message contains a backup of the user's record, and the content of the record defines how to handle the call. Based on this information, the SCP determines the carrier / POTS based on factors such as date and time. The SSP instructs the SCP to send the call to a specific POTS or IC, and the SCP is also required to generate a call record. Business Management System / 800 (SMS / 800) is used to provide services.
- 3 Intelligent Network and Advanced Intelligent Network
- The so-called Intelligent Network (IN) appeared in the mid-1980s, which moved services such as the 800 Directory from a network switch to a Service Control Point (SCP). This method represents a huge improvement. However, in the early stages of its development, the interface (or message) between the switch and the SCP had to be customized to meet the requirements of various services; the switch and the SCP had to be customized for each Business generates customized messages. Nevertheless, the platform provided by IN still allows different vendors to access common resources. With the publication of No. 7, IN provides a standard interface for the software / hardware of different vendors.
- The further development of IN is Advanced Intelligent Network (AIN). AIN does not generate customized messages for specific services like IN, but defines a common, standardized message set for various services. The call processing of the switch and the database processing of the SSP both support a common interface.
- 4 . Summary of Advanced Intelligent Network Technology
- AIN is being used in public telephone networks. It uses standardized procedures and a structured call model to quickly provide customized services. AIN is located on No.7 architecture. It uses TCAP (Transaction Capability Application Part) of No.7 as the message structure and protocol dialogue between AIN nodes.
