Abstract

A technique for the end terminal provided with services to handle QoS process is disclosed. According to this technique, a terminal based QoS management scheme is implemented to achieve end-to-end QoS wherein the end terminal 21 is responsible for handling of the QoS related functions. In order for QoS management to be handled at terminal, the terminal needs to know the network conditions and external state of entities in order to know what action to be taken. For example, the terminal performs monitoring and usage collection. These performance data are then reported to a central server (SLA manager 28). The central server collects these data from all terminals within its administration domain. The central server also has access to information on the QoS to be given to individual terminals, such as service level. Based on the information, the central server decides what action to be taken by individual terminal and enforces these actions into the affected terminals.

Dependent claims

A communication system for achieving end-to-end Quality of Service in a mobile network using terminal centric control comprising:

a terminal with QoS control module that is capable of performing QoS monitoring, reporting and enforcement;
a central controller that accepts QoS reports from the terminal and gives QoS enforcement instructions to the QoS control module in the terminal;
and
a central database that stores subscription information of a user who uses the terminal and service level agreement information.

A communication method in a communication system, wherein the communication system for achieving end-to-end Quality of Service in a mobile network using terminal centric control comprises a terminal with QoS control module that is capable of performing QoS monitoring, reporting and enforcement, a central controller that accepts QoS reports from the terminal and gives QoS enforcement instructions to the QoS control module in the terminal, and a central database that stores subscription information of a user who uses the terminal and service level agreement information, comprising:

a step where the QoS control module collects service and QoS statistics, and feedbacks them to the central controller;
a step where the central controller receives QoS records from the QoS control modules;
a step where the central controller performs QoS management based on the QoS records from the terminal and its subscription information;
a step where the central controller sends QoS enforcement rules to the QoS control module for QoS adjustment;
and
a step where the QoS control module performs QoS enforcement rules sent from the central controller, and also performs local enforcement decisions within itself.
