Abstract

The invention discloses a Platform of Information Switch that adapts for switching the integrated information between the different user terminals and the different services terminals. The Platform includes a Device Access gateway for connecting user terminals and switching the correspondent information, an Information Switch for implementing concentrated management and the integrated information switching, and a Service Gateway for interfacing with the service terminals. Wherein the Information Switch consists of a Management System, a Core Switching System and a Platform Routing System; wherein the Core Switching System includes an Information Bus, Switching Modules and a Switching Management Module. The Device Access Gateway and Service Gateway are both connected to the Information Switch via the Information Buses. The Information Switching Platform of present invention can transform the complex information switching process between the user terminals and service terminals to a simple platform operation.

Claims

1. An information switching platform, comprising:

a device access gateway for connecting a user terminal and converting information;

an information switch for managing and switching information; and

a service gateway interfaced with a service terminal;

wherein the information switch comprises a management system and a core switching system;

the core switching system comprises an information bus, a switching module and a switching management module; and

the device access gateway and the service gateway are both connected with the information switch via the information bus;

wherein a service request information sent by the user terminal is converted to a unique format information by the device access gateway, and the converted service request information is sent to the information switch via the information bus;

according to the service terminal providing the service defined in the service request information, the information switch switches the converted service request information to the service gateway connected with the service terminal; and

the service gateway converts the service request information with a unique format to a format, accessible to the service terminal, and sends to the service terminal, the service terminal receives the service request information; and

wherein the service terminal creates a service acknowledgement information after the service request has been processed and sends the service acknowledgement information to the service gateway, the service gateway converts the service acknowledgement information to a unique format information and sends the converted acknowledgement information to the information switch via the information bus;

according to the user terminal defined in the service acknowledgement information, the information switch sends the converted service acknowledgement information to the corresponding device access gateway; and

then the device access gateway converts the service acknowledgement information with a unique format to a format, accessible to the user terminal, the user terminal receives the service acknowledgement information.

2. The information switching platform according to claim 1, wherein the device access gateway comprises an access gateway, an access monitor, a security manager, a service Interactive Logic and an information format converter.

3. The information switching platform according to claim 2, wherein different services deploy different service interactive logic, and for a service, the same service interactive logic is used for all access gateways.

4. The information switching platform according to claim 2, wherein the access gateway comprises a user interface, which sends user interface to user terminal by different transmission mode;

and a user interface control, which decides which display mode to be used according to the service interactive logic and different user terminals.

5. The information switching platform according to claim 1, wherein the core switching system is an extendable system according to switching capacity requirements.

6. The information switching platform according to claim 1, wherein the information bus is an information interface between the information switch and peripherals, and comprises an information input/output interface and a data communication channel.

7. The information switching platform according to claim 1, wherein the information bus comprises a D-Bus that is an access bus connecting with the device access gateways;
