Problems solved by technology

[0003] During the research and practice of the prior art, the inventor of the present invention found that: the prior art only provides the terminal default MSC Server supports the MAM feature, and can successfully transfer the second session of the normal processing flow; For abnormal situations such as MSC Server does not support the MAM feature or MSC Server cannot successfully transfer the second PS session, no processing procedure is provided

Embodiment 2

[0051] Example 2 has substantially the same results as Example 1. In addition, the single-radio terminal can also consider various situations and set to perform radio frequency switching after receiving the reference information of transferring another session within a set time, so the application is more flexible.

[0052] The embodiments of the present invention will be described in more detail below in combination with Embodiment 3 to Embodiment 5.

[0053] In the prior art, since the UE cannot know the MAM feature of the MSC Server, it defaults that the MSC Server supports the MAM feature. When the UE performs the session handling process, the following situations will occur:

[0054] 1. When the Gm reference point is not reserved, the UE cannot know whether the transfer of the second PS session is successful from the network side, and at this time, the UE will transfer successfully by default. If the MSC Server does not support the MAM feature, the UE will display 2 CS ...

Embodiment 3

[0058] In the third embodiment, the UE subscribes to the SCC AS for the transition state of the second session, or information about whether the MSC Server supports or does not support the MAM feature.

[0059] image 3 It is a flow chart of the session processing method in Embodiment 3 of the present invention, which mainly includes steps:

[0060] Step 301, UE-1 initiates a subscribe request message to the SCC AS, requesting to subscribe to the transition status of the second session associated with the UE in the network, or the MAM feature (supported or not) of the MSC Server.

[0061] The event Event contained in the subscribe request message is: second_session (indicates the transfer status of the second session) or mam (indicates the MAM feature of MSC Server).

[0062] The subscribe message also includes the Instance ID or MSISDN for associating the UE. The Instance ID can be included in the connection (contact) message header, and the MSISDN can be included in the pr...

Embodiment 4

[0109] The main difference between the fourth embodiment and the third embodiment is that the SCC AS actively informs the UE of the transfer status of the second session, whether the MSC Server supports the MAM feature or indicates whether the terminal uses the MAM feature.

[0110] In Embodiment 4, it is assumed that the MSC Server does not support the MAM feature, the UE currently establishes two PS voice sessions in the PS access network, the session (the first session) between UE-1 and UE-2 is in the active state, and UE-1 The session (second session) with UE-3 is in hold state. Moreover, each UE is currently in the LTE network, and will be handed over to the UMTS network later.

[0111] Figure 4 It is a flow chart of the conversation processing method in Embodiment 4 of the present invention, which mainly includes steps:

[0112] Steps 401-405 are the same as steps 303-307 in the second embodiment, please refer to the description in the embodiment for details.

Abstract

The embodiment of the present invention discloses a session processing method and a communication device. The session processing method includes that an application server receives a session transferring request message; the application server transfers an activated session of a single radio frequency terminal according to the session transferring request message and provides a reference information for transferring another session to the single radio frequency terminal to make the single radio frequency terminal process the another session according to the reference information. The embodiment of the present invention also provides a corresponding application server and a corresponding single radio frequency terminal, and the technical scheme provided by the embodiment can perform session processing according to different conditions.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a session processing method and a communication device. Background technique [0002] In the IP Multimedia Subsystem (IMS, IP Multimedia Subsystem) network, it includes a call session control function entity (CSCF, Call Session Control Function) and an application server (AS, Application Server), wherein the CSCF can be divided into a proxy call session control function entity ( P-CSCF), serving call session control function entity (S-CSCF) and interrogating call session control function entity (I-CSCF). AS performs service control through interaction with S-CSCF. The core of the service continuity (SC, Service Continuity) technology is the service centralization and session continuity application server (SCC AS, Service Centralization&Continuity Application Server). The SCC AS completes the transfer function between access legs (Access Legs) between different...
