Problems solved by technology

[0004] In the process of implementing the present invention, the inventor found that the prior art does not provide a method for how to transfer the session of the UE when the UE includes a video session and a voice session at the same time, so that when the UE includes both a voice session and a video session , the session of the UE cannot be transferred

Embodiment 1

[0056] Embodiment 1: The UE transfers from the PS domain to the CS domain. The UE includes an active video session and an inactive voice session. Both the UE and the network side support the SCUDIF feature.

[0057] Such as image 3 As shown, the session transfer method provided by the embodiment of the present invention includes:

[0058] In step 301, the UE determines that the video session is in an active state.

[0059] In this embodiment, the UE has stored session state information, and may determine that the video session is in an active state according to the session state information.

[0060] In step 302, the UE initiates a transfer of the video session to the network side, so that the network side transfers the video session to the CS domain.

[0061] Such as Figure 4 As shown, the step 302 may include:

[0062] Steps 401-403, the UE sends the first CS domain call establishment request to the SCC AS through the MSC Server and the Serving-Call Session Control Fun...

Embodiment 2

[0088] Embodiment 2: The UE transfers from the PS domain to the CS domain. The UE includes an active video session and an inactive voice session. The UE and / or the network side do not support the SCUDIF feature.

[0089] This embodiment is as image 3The steps shown in Implementation 1 are basically the same, the differences are:

[0090] When the UE initiates the transfer of the video session to the network side, so that the network side transfers the video session to the CS domain, since the UE and / or the network side do not support the SCUDIF feature, the application for the transmission bearer of the circuit switched domain is related The information is the information for applying for multimedia bearer;

[0091] In the CS domain, when the session state is switched between the video session and the voice session, the UE uses the multimedia bearer to transmit the media stream of the voice session; optionally, the UE and the MSC Server can interact through H.245 signaling, ...

Embodiment 3

[0092] Embodiment 3: The UE is transferred from the PS domain to the CS domain. The UE includes an inactive video session and an active voice session. Both the UE and the network side support the SCUDIF feature.

[0093] Such as Image 6 As shown, the session transfer method provided by the embodiment of the present invention includes:

[0094] In step 601, the UE determines that the voice session is in an active state.

[0095] In this embodiment, the UE pre-stores session state information, and may determine that the voice session is in an active state according to the session state information.

[0096] In step 602, the UE initiates a transfer of the voice session to the network side, so that the network side transfers the voice session to the CS domain.

[0097] Such as Figure 7 As shown, the step 602 may include:

[0098] In steps 701-703, the UE sends the first CS domain call establishment request to the SCC AS through the MSC Server and the Serving-Call Session Con...

Abstract

The invention discloses a conversation transfer method and user equipment and relates to the field of communication, and the method and user equipment provided by the invention are used for solving the problem that the conversation transfer can not be conducted when the UE (user equipment) comprises voice conversation and video conversation simultaneously. According to the technical scheme provided by the invention, the conversation transfer method comprises the following steps of: determining a conversation in an activated state from the video conversation and the voice conversation; and lunching transfer of the conversation in the activated state so as to transfer the conversation in the activated state from a network side to a circuit switching domain, and transferring conversations in an unactivated state in the video conversation and the voice conversation. The embodiment of the invention can be applied in wireless communication networks.

Description

[0001] This application is a divisional application of an invention patent application with the patent number 200910139157.1 and the invention title "Session Transfer Method and User Equipment" submitted to the Patent Office on May 5, 2009. The entire content of this application is incorporated by reference in this application. technical field [0002] The present invention relates to the communication field, in particular to a session transfer method and user equipment. Background technique [0003] In the prior art, when a user equipment (User Equipment, UE) transfers from a packet switched (Packet Switched) domain to a circuit switched (Circuit Switched, CS) domain, if the UE includes multiple voice sessions, the UE may Determine a target voice session in a voice session, initiate a transfer request to the target voice session to the service centralization and session continuity server (Service Centralization and Continuity Application Server, SCC AS) on the network side, ...
