Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method and apparatus of content type identification.
Background technology
In the communications field, the mode that operator charges mainly contains charged according to time and the dual mode of charging by flow.For example charge at the duration that uses by speech business to the general employing of speech business.The data bit flow of actual generation when carrying out a certain communication service by the user of charging by flow charges.In non-voice service, the employed flow of different communication services is widely different.For example, the professional flow of short message service and video TV is just in an one magnitude, and the shared Internet resources of two business are also different.Operation cost to unique user is discrepant owing to the difference of customer service in operator; Charged according to timely can better not carry out the differentiation of this respect: charging by flow then can address this problem, but charge by flow certain limitation is arranged also: if for example non-real time service such as real-time service such as visual telephone business and music download business is all chargeed by flow and just seemed unreasonable.Because the shared Internet resources of different service are different, just operator is inequality for the cost that the user who uses different business drops into, if but the identical economic law of just obviously running counter to of charging way.Therefore, charge by flow merely, all can not embody the value of content in the communication service well with charged according to time the same.
Along with the development of data service, the kind that various data services are used becomes increasingly abundant, and based on the charging way of flow or duration because its shortcoming can't satisfy the charging demand of operator, introduced mode thus by content charging.Be meant that by content charging operator through packet is filtered and analyzes, discerns and distinguish the content type and the attribute of packet then, and be sent to charge system to relevant information and charge.With charge different according to duration or flow is that content charging can be chargeed according to the content type of value-added service, can the user be made flexibly, reasonably charge according to the content information of communication service like this.
