Method and system for optionally switching conversation on both sides in calling service

Abstract

The invention discloses a method and system for optionally switching a conversation on both sides in calling service, wherein the method comprises the following steps: in the process that a first user terminal and a second user terminal communicate with each other through an AS (application server), when the AS knows that the first user terminal keeps the present conversation and the AS receives a request message for the first user terminal to carry an optional switching service code, the AS enables the first user terminal and a third user terminal related to the request message to have media negotiation with each other and enables the second user terminal and the third user terminal to have media negotiation with each other so as to establish a conversation between the second user terminal and the third user terminal; and then, the conversation between the first and second user terminals is cut off. In the invention, the method and the system are unrelated to terminals without needing a terminal to support the function of sending a refer message, and various types of terminals on the present network can be operated; and the conversion can be switched to a bound user, or, the conversation can be switched to an appointed user.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a system for realizing random switching between two parties in a calling service. Background technique [0002] Traditional post-call switching services are implemented through call transfer, including blind transfer and inquiry transfer. This type of switching requires the terminal to support sending refer (indication) messages. [0003] Such as figure 1 As shown, it is a schematic diagram of using the refer message in the prior art to realize the random switching between the two parties, wherein, during the conversation between users A and B (through user terminals UE-A and UE-B), B adopts a call hold mode to maintain the communication with A Then, use the refer message to switch the call from AB to AC. [0004] However, it is generally a relatively high-end terminal that has the ability to send refer messages, and ordinary terminals usually do not have this capability....

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and propose a method and system for realizing the random switching between two parties in the call service, so as to solve the problem of how to make the ordinary terminal have the function of switching after the call during the call. question
