Abstract

The invention discloses a domain switching method, a server and a control device. The domain switching method comprises that: a call session control device receives a call request initiated by the terminal which uses a session transfer identifier as a called address and routes the call request to a server, wherein the session transfer identifier is pre-allocated by the server and used for identifying the session and the domain switching of the session; and the server acquires the call request according to the session transfer identifier I the call request and uses the call request to perform the domain switching of the session correspondingly. In the embodiment of the invention, according to the dynamically allocated STID, the domain switching of the session is performed, the domain switching correctness and effectiveness can be ensured effectively, the diversified development of a network service is promoted, network resources are saved, and domain switching efficiency is improved.

Description

technical field

[0001] The invention relates to mobile communication technology, in particular to a domain switching method, server and control device. Background technique

[0002] The core network of the Universal Mobile Telecommunications System (hereinafter referred to as: UMTS) is a combination of the Global System for Mobile Communications (hereinafter referred to as: GSM) and the General Packet Radio Service (hereinafter referred to as: GPRS). ) developed on the basis of the Internet Protocol (Internet Protocol, hereinafter referred to as: IP) backbone network. It can be logically divided into a circuit-switched (Circuit-Switched, hereinafter referred to as: CS) domain and a packet-switched (Packet-Switched, hereinafter referred to as: PS) domain. The CS domain is the circuit switching core network of UMTS, which is used to support circuit data services; the PS domain is the packet service core network of UMTS, which is used to support packet data services and some m...
