Description

Service quality gateway, service quality level mapping implementation system and method thereof

The present invention relates to the field of communications, and in particular, to a service quality gateway, a system for implementing a quality of service level mapping, and a method thereof. Background technique

QoS (Quality of Service) is a control mechanism that provides different levels of priority for different users or different data streams, or ensures that the performance of the data stream reaches a certain level according to the requirements of the application. .

QoS guarantees are important for networks with limited capacity, especially for streaming multimedia applications such as Voice over Internet Protocol (VoIP) and Internet Protocol Television (IPTV). Applications often require a fixed transmission rate and are sensitive to latency.

The user's direct perception of QoS is the quality of service obtained; the operator can formulate different operational strategies for different QoS levels to meet the needs of different applications of users. Therefore, in multiple network convergence based on the all-IP architecture, how to make the terminal maintain the same QoS level under each network becomes a concern of both operators and users.

For example, when the mobile terminal belonging to the network A roams to the network B, if the network B does not provide the appropriate QoS to the mobile terminal, the quality of some applications on the terminal may be degraded (for example, the QoS cannot be provided to the VoIP service, which may result in Voice quality is degraded). Therefore, network B must integrate its own network conditions and the contracted QoS of the terminal in the home network to provide the QoS to the roaming terminal to meet its service requirements.

At present, in the mobility schemes developed by various standards organizations, each mobile communication system has an independent access network QoS scheme, and users can enjoy the contracted QoS level under their home network. However, because the definitions of QoS parameters of each communication system are different, it is not conducive to users enjoying the same QoS level under multiple networks.
