Problems solved by technology

[0004] However, in the VoIMS APP solution, since the Policy Control and Charging (PCC) system is not introduced, the Packet Data Network Gateway (PGW) can only establish the quality of service for the signaling flow and media service flow by default. A default bearer with a Quality of Service Class Identifier (QCI) of 9
In this way, when the network is congested, the voice conversation quality of the service will be degraded, which will affect the user experience

Embodiment Construction

[0032] In the embodiments of the present invention, words such as "exemplary" or "optionally" are used as examples, illustrations or illustrations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present invention shall not be construed as being more preferred or more advantageous than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete manner.

[0033] The application scenario of this application can be in the IMS network architecture, based on the SBC trigger voice service quality assurance, such as figure 2 As shown, the networking architecture of the whole solution is mainly composed of the terminal part, 4G access side, EPC and IMS network.

[0034] The terminal part is mainly in the form of an APP client. Users can use the APP client to use VoIMS voice services by downloading and installing the APP client on the termin...

Abstract

The embodiment of the present application discloses a service quality assurance method and device, which relate to the communication field and can provide quality assurance for voice services when VoIMS voice services are accessed from a mobile network. The method is as follows: the SBC receives the voice service request message sent by the terminal, and determines whether the terminal accesses from the mobile network according to the voice service request message; if it is determined that the terminal accesses from the mobile network, the SBC sends a session message to the PCRF, and the session message is used to request A dedicated bearer is established for the service flow of the voice service. The quality of service level of the dedicated bearer is higher than that of the default bearer. The default bearer is a bearer established for the signaling flow of the voice service. The embodiment of the present application is used to establish a dedicated bearer for the voice service when the VoIMS voice service is accessed from a mobile network to ensure service quality.

Description

technical field [0001] The present application relates to the communication field, in particular to a service quality assurance method and device. Background technique [0002] During the development of operators' voice services, due to the small number of terminals supporting HD Voice (Voice over Long Term Evolution, VoLTE) and the high price, and the poor service quality of OTT VoIP (Over The Top Voice over Internet Protocol) , Operators are uncontrollable and other issues, making the OTT (Over The Top) solution based on the Internet Protocol (Internet Protocol, IP) Multimedia Subsystem (IP Multimedia Subsystem, IMS) network to provide voice services become the fourth generation mobile communication technology (4th- Generation mobile communication technology (4G) / 5th-Generation mobile communication technology (5G) stage, except for VoLTE and OTT VoIP, mainstream voice solutions. [0003] Among them, the OTT solution can also be called the VoIMS APP (Voice over IP Multimed...
