Title
(EN) Cross-system call setup method, terminal and core network element
(ZH) 一种跨系统呼叫建立方法、终端及核心网网元
Abstract
(EN)
The invention discloses a cross-system call setup method, a terminal and a core network element. The method comprises the following steps: sending a call setup request carrying a call type and identification of a called system to a base station, and thus enabling a core network of a system to receive the call setup request sent by the base station; extracting a corresponding called number from the call setup request; finding the number of the called system according to the mapping relation between a preset system identification and system numbers, sending the number of the called system and the called number to a system gateway, and thus enabling the system gateway to send the called number to a called system gateway according to the number of the called system; enabling the called system gateway to send the called number to the called system, and thus enabling the called system to set up a cross-system call according to the called number; receiving broadcast signaling carrying service channel information sent by the base station, and switching to a corresponding service channel according to the service channel information. The scheme can flexibly realize the cross-system call service.
