Patent number: 8369232Abstract: A terminal device includes a service type distinguishing module and a traffic measuring module. The service type distinguishing module is adapted to distinguish types of services accessed by the terminal device; the traffic measuring module is adapted to measure the traffic of each service type according to the service types distinguished by the service type distinguishing module. The present disclosure also discloses a system and method for measuring traffic based on user services. With the technical scheme of the disclosure, traffic of different service types can be measured respectively on a terminal device, so that the charging system is able to apply different charging policies to different service types.Type: GrantFiled: July 17, 2008Date of Patent: February 5, 2013Assignee: Huawei Technologies Co., Ltd.Inventors: Feng Wang, Tao Jiang, Wei Huang, Peilong Tan, Jun Zhao
