Problems solved by technology

[0006] When a terminal with two voice processing capabilities switches between networks that support the above two voice processing methods, the terminal may adopt either of the two supported voice processing capabilities, so the evolved base station (eNodeB) in the network ) cannot know which voice processing method the terminal adopts before switching, so it is impossible to know the switching process of which voice processing method to use, resulting in the failure of voice service switching and affecting the continuity of voice services
That is, the current network can only support one voice processing method, and cannot handle voice services when two or more voice processing methods coexist, so as to maintain continuity
For example, if the terminal adopts CSoPS voice processing mode, but the network side performs the bearer switching process of SRVCC voice processing mode, it will inevitably lead to the failure of voice bearer switching

Embodiment 1

[0048] Embodiment one, see image 3 Detailed description, image 3 It is a schematic flow chart of the method in this embodiment.

[0049] Step 101: In the source network, when the terminal needs to initiate a voice service, determine the voice processing mode of the terminal in the source network. The voice processing mode adopted by the terminal may be determined by the MME, the terminal, or an initiating device in the network.

[0050] In this step, the MME may further know the voice processing mode of the source network of the terminal, and may further save or notify the eNodeB of the voice processing mode of the terminal in the source network.

[0051] a. When the terminal initiates a voice service or performs a voice service on the source network, the MME supports the voice processing capability provided by the terminal itself (supports one or more types), and the voice processing capability supported by the source network side (supports one or more At least one of th...

Embodiment 2

[0073] Embodiment 2 explains in detail the flow of the MME determining the voice processing mode adopted by the terminal according to the voice processing capability supported by the terminal, the voice processing capability supported by the source network side, and the operator's policy.

[0074] Embodiment two, see Figure 4 Detailed description, Figure 4 It is a schematic flow chart of the method in this embodiment.

[0075] Step 201: UE provides its own voice processing capability to the MME, and learns that the source network supports the voice processing capability.

[0076] The UE may provide the MME with its own voice processing capability through the attach request message, or the UE may provide its own preferred voice processing mode while providing the capability. The MME can send the supported voice processing capability to the UE through an Attach Accept message. Alternatively, according to step 203, after it is determined to adopt a voice processing mode, the...

Embodiment 3

[0086] Embodiment 3 On the basis of Embodiment 2, a new step is added in which the MME sends the voice processing mode adopted by the network side to the eNodeB, and then switches the voice bearer according to the switching instruction of the eNodeB.

[0087] Embodiment three, refer to Figure 5 Detailed description, Figure 5 It is a schematic flow chart of the method in this embodiment.

[0088] Step 301: UE provides its own voice processing capability to the MME and learns that the source network supports the voice processing capability.

[0089] Step 302: The MME learns the voice processing mode adopted by the terminal in the source network.

[0090] A specific manner may adopt the processing manner described in step 203 .

[0091] Step 303: Inform the eNodeB of the learned voice processing manner.

[0092] The MME may inform the eNodeB of the acquired voice processing mode, or the UE may notify the eNodeB of the adopted voice processing mode in a radio resource contro...

Abstract

The embodiment of the invention discloses a method and a device for maintaining voice business continuance and a communication system. The method comprises the steps of: obtaining a terminal requirement for voice switching by an MME (Mobile Management Entity); acquiring a voice treatment mode adopted by a terminal needing switching in a source network; and initiating voice bearing switching to a target network by adopting a voice treatment mode adopted by the terminal. The invention ensures that a network side can acquire the voice treatment mode adopted by the terminal, thereby initiating the voice bearing switching process to the target network by the voice treatment mode adopted by the terminal, maintaining the continuance of the voice business, and improving the user experience.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method, device and communication system for maintaining continuity of voice services. Background technique [0002] Both the user terminal (UE) and the network side can support CS domain services over evolved PS access (CSoPS) and single access system voice continuity (Single Radio Voice Call Continuity, SRVCC). A voice processing method. Therefore, when a terminal with two voice processing capabilities moves to a network supporting two voice processing modes, the voice service of the terminal can be implemented by using the CSoPS or SRVCC voice processing mode. For example, the terminal is switched from a Long Term Evolution (Long Term Evolution, LTE) network to a Terrestrial Radio Access Network (UMTS Territorial Radio Access Network, UTRAN) or a GSM (GPRS) / EDGE Radio Access Network (GSM (GPRS) / EDGE Radio Access Network, GERAN circuit domain (Circuit switch, CS), the v...
