In the differentiated charging method in the embodiment, the AVP is described by the extended media component, the media state is increased to identify the early media or the common media, and the differentiated charging of the early media is realized by the cooperation of the P-CSCF, the PCRF and the P-GW.
The media status information in the AAR includes: Media-Status attribute value pair AVP, the Media component description in AAR is represented by AVP. The AVP is implemented in the form of Attribute-Length-Value triplets, and the Media-Status AVP is used to indicate the Media type.
The media states include: early media, normal media. Early media refers to media sent by the call service prior to session establishment, including: color ring back tone, etc. The common media include audio, video, etc. after the call service is established. For example, when the value of the attribute Media-Status in the Media-Status AVP is 1, the Media is identified as a color ring, when the value of the attribute Media-Status in the Media-Status AVP is 2, the Media is identified as audio, and when the value of the attribute Media-Status in the Media-Status AVP is 3, the Media is identified as video. The value of the attribute Media-Status may be set according to a specific system or scene for identifying a Media type. PCRF distributes charging charge group for different early media and common media, and sends information such as charging charge group to P-GW.
When the processed call service comprises the early media and the common media, the P-CSCF respectively sends a first AAR message and a second AAR message to the PCRF aiming at the early media and the common media.

When only normal media is included in the processed call traffic, the P-CSCF22 sends an AAR message to the PCRF for the normal media. The Media-Status AVP in the AAR message indicates normal Media.
The PCRF21 obtains the Media-Status AVP from the AAR message, and determines that the Media is early Media or ordinary Media according to the Media-Status AVP. The PCRF21 is pre-configured with different charging tariff groups for early media and normal media. The PCRF21 obtains the Media Component Number Media-Component-Number attribute value pair AVP, the Media Type Media-Type attribute value pair AVP, and the Media-Status AVP from the AAR message, and allocates a charging tariff group corresponding to the early Media and the normal Media based on the Media-Component-Number AVP, the Media-Type AVP, and the Media-Status AVP, and the PCRF21 sends the charging tariff group information to the packet data network gateway P-GW23 through the Gx interface.
