Problems solved by technology

[0028] The inventors found that in the method for implementing single-standby service continuity in the related art above, after the handover command arrives at UE-1 and UE-1 is handed over to the target network (that is, the above-mentioned step 113), between UE-1 and UE-2 The call has been interrupted, and the call can only be resumed after the IMS session transfer process and the dedicated bearer establishment process are completed, which results in a longer call interruption time and reduces user experience

Embodiment 1

[0043] figure 2 It is a schematic structural diagram of a system for implementing reverse single-standby service continuity according to Embodiment 1 of the present invention. The system includes: a source network control entity 10 , a core network 20 and a target network control entity 30 . Wherein, the source network control entity 10 is configured to request the core network 20 to create a bearer when receiving the handover request, and notify the target network control entity 30 to execute the handover process after receiving the message that the bearer is created successfully; the core network 20 is used to Create a bearer; the target network control entity 30 is used to execute the switching process after receiving the notification from the source network control entity 10, switch the bearer created by the core network 20 to the target network, and establish the switched terminal and remote device through the bearer media connection between.

Embodiment 2

[0056] Figure 4 It is a schematic structural diagram of a system for implementing reverse single-standby service continuity according to Embodiment 2 of the present invention. This embodiment is a specific implementation manner of Embodiment 1. In this embodiment, the source network control entity 10 is a mobile switching Center (MSC).

[0057] Taking UE-1 to establish a call with UE-2 through CS domain access as an example to illustrate the reverse single-standby service continuity solution in this embodiment, since UE-1 realizes the call through the CS domain of the 2 / 3G network, therefore A section of CS media connection is connected to UE-1 in the call media path. Figure 5 In this embodiment, when UE-1 is handed over to the target network accessed by the PS domain, the signaling flowchart for realizing reverse single-standby connectivity mainly includes the following steps:

[0058] Steps 501-502, and figure 1 Steps 101 to 102 are the same;

[0059] Step 503, the MSC...

Embodiment 3

[0076] Figure 6 It is a schematic structural diagram of a system for implementing reverse single-standby service continuity according to Embodiment 3 of the present invention. The difference between this embodiment and Embodiment 2 is that the source network data domain control entity (such as SGSN) requests the core network to create a bearer. In this embodiment, no matter whether the UE is in data service or not, the source network base station system will send a handover request to the source network data domain control entity. After receiving the handover request, the source network data domain control entity requests the core network to create a bearer.

[0077] Figure 7 It is a signaling flow chart of the implementation method of reverse single-standby service continuity in this embodiment, in Figure 7 Among them, UE-1 establishes a conversation with UE-2 through the CS domain of the 2 / 3G network. In this embodiment, the implementation method of reverse single-standb...

Abstract

The invention discloses a method and system for realizing reverse single-standby service continuity. The method includes: the source network control entity receives the handover request; the source network control entity requests the core network to create a bearer; the source network control entity notifies the target network control entity to execute the handover process and switches the created bearer to the target network; the terminal switches to the target network Finally, the media connection with the remote device is established by switching to the bearer of the target network. Through the present invention, the call interruption time in reverse standby service continuity can be reduced and user experience can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and system for realizing reverse single-standby service continuity. Background technique [0002] IP Multimedia Subsystem (IPMultimediaCoreNetworkSubsystem, referred to as IMS) is an IP-based network architecture proposed by the 3rd Generation Partnership Project (3rdGeneration Partnership Project, referred to as 3GPP), which builds an open and flexible business environment and supports multimedia applications. It can provide users with rich multimedia services. [0003] In the IMS service system, the control layer and the service layer are separated, and the control layer does not provide specific services, but only provides necessary functions such as triggering, routing, and charging to the service layer. [0004] The service triggering and control functions in the control layer are implemented by a call session control function (CallSessionControlFunction, CSCF fo...
