Embodiment Construction

[0034] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0035] The basic idea of ​​the present invention is to provide a free call switching service between two parties. User A maintains user B during the call with user B. By dialing the service code or the service code plus a specified number, the service switches the call of user A to user B. After C logs out user A, BC and BC both talk. Afterwards, the current call can be maintained in B or C, and the call can be switched to other users by dialing the service code or the service code plus the specified number. Switch back to user A and user C logs out, and AB and AB talk. Of course, user C can also switch the call to other users, such as user D. In this way, random switching of...

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....
