Embodiment Construction

[0028] Hereinafter, the implementation method and system of the call pickup service in the communication mode in the communication system of the present invention will be described in detail with reference to the accompanying drawings 1-5.

[0029] The core idea of ​​the present invention is: when calling user A and user B are in the communication state, user C dials user B, at this time, user D of the same group as user B dials the phone number of service access code + B, by judging user D After having the permission to pick up user B, user C and user D enter the conversation state.

[0030] Hereinafter, the present invention uses the call control signaling SIP as an example to describe the implementation method and system of the call pickup service in the communication system of the present invention, but it is not limited to this protocol, and also includes H323 and H248 protocols.

[0031] As shown in Figure 1, it is a flow chart of the call pickup service in the communica...

Abstract

The invention provides a method and a system for realizing a connected status pickup service in the communication system, wherein, when a first calling party and a called party is in the connected status and a second calling party dials the number of the called party, a pickup party which is provided with a called party pickup permission processes to answer in stead to enter into the connected status with the second calling party. According to the method and the system for realizing the connected status pickup service in the communication system of the invention can guarantee that in the connected status, user still can be called, so as to guarantee timeliness of message and improve call completion rate.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and system for realizing call pickup service in communication mode in a communication system. Background technique [0002] At present, the IP network is developing at an incomparable speed. Different from the traditional circuit switching network, the IP network transmits voice on the basis of transmitting data, and mainly deals with the intercommunication between different call control signaling. Telecom services based on IP networks have become a part of people's lives, a part of telecom operators' continuous expansion of business capabilities to meet the needs of people's lives, and a new growth point for telecom operators to generate revenue. Among them, the call pick-up (Call Pick Up) service is an important telecommunication service, and the current domestic and foreign patents are all about the call pick-up in the ringing state. For example, a pate...
