Problems solved by technology

[0019] 1. Call transfer can only be realized within the same SCP, and call transfer across SCPs cannot be realized;
[0020] 2. All business logic instances must be installed on the same machine. The degree of business coupling is high. The upgrade of one business logic instance may lead to the linkage upgrade of other business logic instances. The cost of system development and maintenance is high.

Embodiment Construction

[0048] The invention provides a cross-service control point call transfer method. The core of the present invention is: the present invention is based on the TCAP specification in the standard No. 7 signaling network, so it is not limited to any proprietary protocol that may exist in the existing communication network.

[0049] SS7 (Signaling No. 7 network) is one of the three major supporting networks of the telecommunication network and an important part of the telecommunication network. It is widely used, PSTN (public switched telephone network), GSM, WCDMA (wideband code division multiple access) And so on are using SS7 as the signaling network. TCAP is a high-level protocol of SS7 used to support transaction-based applications.

[0050]The TCAP specification in the No. 7 signaling network stipulates that when two TC (transaction processing)-users (A, B) communicate through TCAP, it is assumed that user A is the side that initiates the transaction, and user B is the side ...

Abstract

The invention relates to a cross business control point calling transfer method which mainly comprises: the business control point receives the calling trigger message of the business exchange point; the business control point transfers the calling trigger message to other business control points; other business control point receives the calling trigger message and directly dose business exchange points communication to process the calling.

Description

technical field [0001] The invention relates to the field of communication, in particular to a call transfer method across service control points (SCP). Background technique [0002] With the development of networks and services, intelligent network technology has been more and more widely used in many fields, and the integrated intelligent network can provide services for various service networks. It can not only serve fixed networks, mobile GSM (Global System for Mobile Communications) networks, CDMA (Code Division Multiple Access) networks, and IP (Internet Protocol) networks, but also provide users with various services conveniently, such as one-card services, comprehensive VPN (Virtual Private Network) service, prepaid service, Internet service, etc. [0003] The intelligent network is composed of SSP (service switching point), SCP (service control point), SDP (service data point), and SMS (service management system). [0004] The main functions of SSP include: respon...
