Abstract

The invention relates to a method and a device for establishing a call on busy. The method can include responding to a called party to be busy in calling, and requesting to perform calling queuing at a user terminal of a calling party; responding to an event, from an application server, of instruct and subscribe the called party to queue; receiving information of queuing state of instructing the called party to perform calling queuing at the user terminal of the calling party after the calling party hangs off, wherein the queuing state at least includes instructing record number of calling located at the position in a queue; and responding to a notice of position of state of to be currently processed of the calling in the queue, and generating a prompt tone at the user terminal of the calling party to prompt the calling party to off-hook.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a method and device for establishing a call when busy. Background technique [0002] With the rapid development of network technology, in recent years, mobile communications have shown a tendency to evolve to an all-IP network architecture, and network integration based on IMS (IP Multimedia Subsystem) has become a hot spot for applications. IMS is a new core network domain defined by 3GPP (Third Generation Partnership Project) in UMTS R5 and later versions, and supports IP-based networks that handle traditional audio telephony and multimedia services. 3GPP chooses SIP (Session Initiation Protocol) as the core session signaling protocol, which is developed by the Internet Engineering Task Force (IETF) for session establishment, modification and teardown, and is independent of media transmission.
