Problems solved by technology

However, if the user equipment selected by the SCC server to access the call is not with the user, or the user equipment selected to access the call has already conducted a session in a joint session and does not have the control right, the previous session cannot be maintained, which will cause The call cannot be connected, making the user experience poor

Embodiment 1

[0045] A method for establishing a session. The applicable scenario of the method in the embodiment of the present invention is: User A is in a joint session, that is, at least two user equipments of the user A are in the session. In this embodiment, two are used as an example. Assume that it is UE-1 and UE-2; and the user A has a session of user equipment UE-2: with user B's user equipment Remote UE-1 in the CS domain, the real-time media stream Media-B is transmitted, then When another user C uses the user equipment Remote UE-2 to initiate a call request to user A for real-time media stream transmission, the session establishment process of the embodiment of the present invention will be initiated. The signaling flow chart is as follows figure 2 shown, including:

[0046] Step 101, user equipment Remote UE-2 initiates a call request message to user A, and includes the identification information of called user A in the call request message;

[0047] It can be understood that...

Embodiment 2

[0063] A method for establishing a session. The method of the embodiment of the present invention is a specific implementation of the embodiment. The applicable scenario is the same as that of the first embodiment, and will not be described again. The signaling flow chart is as follows image 3 shown, including:

[0064] Step 201, user equipment Remote UE-2 initiates a call request message to user A, and includes the identification information of called user A in the call request message;

[0065] Step 202, the call request message will arrive at the SCC server through the CSCF of the network where the called user A is located, and the SCC server determines whether the called user A has a joint session according to the identification information in the call request message, if so, perform step 203; if not, then Perform follow-up operations according to existing techniques, refer to figure 1 Steps 3-6 of ;

[0066] The method for the SCC server to determine whether a joint se...

Embodiment 3

[0081] A method for establishing a session. The method in the embodiment of the present invention is a specific implementation of the embodiment. The applicable scenario is the same as that in the first embodiment, and will not be described again. The flow chart is as follows Figure 4 shown, including:

[0082] Step 301, user equipment Remote UE-2 initiates a call request message to user A, and includes the identification information of called user A in the call request message;

[0083] Step 302, the call request message will reach the SCC server through the CSCF of the network where the called user A is located, and the SCC server selects the user equipment for accessing the call from among the user equipment of the called user A according to the identification information in the call request message, And select the access network for the user equipment to access the call, that is, perform the T-ADS function. In this embodiment, the selection of the user equipment UE-2 to acc...

Abstract

The embodiment of the invention discloses a called processing method, a system and a network node, applied to the technical field of communication. In the called processing method adopted by the embodiment of the invention, an SCC (Supervisory Control Computer) server receives a call request message, and if a called user is confirmed to be in a collaborative session, the call request message is sent to control user equipment in the collaborative session. Therefore, when the user is in the collaborative session and other users initiate a new call to the user by using user equipment, the SCC server selects the control user equipment in the collaborative session, thus, the SCC server has no control right and cannot maintain a previous session because the selected user equipment accessing thecall is not around the user or the selected user equipment accessing the call is already in the collaborative session for session, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a called processing method, system and network node. Background technique [0002] In the multimedia service communication network of communication technology, the network protocol multimedia stream system (IPMultimedia Subsystem, IMS) is a next-generation communication network that can realize the integration of various networks (such as mobile and fixed networks, packet switching networks, circuit switching networks, etc.) The core technology can support voice, video, data and other media streams and their combined services. In the IMS network, the IMS core network subsystem is used for service control, the packet switched network (PS) or the circuit switched network (Circuit Switched, CS) is used as the access network, and the call session control function entity (Call Session Control Function, CSCF) provides The core IMS session control function. Among them, CSCF can ...
