Value, specific calculating process is as shown in Fig. 2 the calculating process includes：
201, PGW call DPI (Deep Packet Inspection, deep-packet detection) to carry out business knowledge to packet
Not, target service corresponding to the packet is obtained to identify.
Wherein, target service mark can be title, icon, ID (IDentity, identity) number corresponding to the target service
Deng.
202, PGW obtain business IP precedence value IPP_S and business corresponding to target service mark in service priority table
Packet loss priority value DP_S.
It should be noted that the service priority table of this step can be as shown in table 1.
| Service identification | Business IP precedence value IPP_S | Business packet loss priority value DP_S |
| 5 | 0 | |
| Mobile phone QQ | 4 | 1 |
| A sudden peal of thunder is downloaded | 3 | 2 |
| Baidu map | 2 | 3 |
Table 1
Wherein, the service identification in table 1 is to be illustrated by taking Business Name as an example.
In service priority table, the business IP precedence value IPP_S of acquisition is designated as IPP_S, business packet loss priority
Value DP_S is designated as DP_S.
It should be noted that the service priority table is stored in advance in PGW.According to the different demands of Operator Specific Service,
To carry out different settings to the priority of business in advance, table 1 can be directed to business IP precedence corresponding to the setting of specific business
With packet loss priority.The differentiation of priority, such as instant messaging service can not only be carried out to business by service priority table,
As wechat business, mobile phone QQ business can carry out the setting of different priorities by service priority table, reach to refine to and be directed to
Specific business carries out the purpose of different transmission；The business that concern can also be compared operator ensures, such as certain
Individual specific transactions：Wechat, according to the business consideration to factors such as time delay, shake, packet losses in use one can be selected to be adapted to
The business IP precedence and packet loss priority of the business.
What deserves to be explained is table 1 illustrate only the priority of 4 business, service priority Biao Kegen in practical situations both
Additions and deletions and modification are carried out to the business in service priority table according to actual conditions.It should be noted that table 1 illustrate only business mark
Knowledge, business IP precedence value IPP_S, business packet loss priority value tri- parameters of DP_S, in practical situations both service priority table
Additions and deletions and modification can be carried out to the parameter in service priority table according to actual conditions.
For example, operator can increase the affiliated bearing parameter of business in service priority table, table 2 specifically can refer to.
Table 2
Operator refers to business affiliated bearing parameter and IPP_S and DP_S is preset.It is assumed that in dedicated bearing
Significance level be higher than in the case of default bearing, the IPP_S of business corresponding to dedicated bearing can be set higher than default bearing correspondence
Business IPP_S, the DP_S of business corresponding to dedicated bearing be less than business corresponding to default bearing DP_S.Such as in table 2
Dedicated bearing is carried as belonging to the business of wechat business, default bearing is carried as belonging to the business of sudden peal of thunder downloading service, then to be micro-
The IPP_S of communication service setting is higher than sudden peal of thunder downloading service, and the DP_S of wechat business is less than the DP_S of sudden peal of thunder downloading service.
How advance setting is done to IPP_S and DP_S according to the affiliated bearing parameter of business in the present invention not limit,
Specifically different situations can specifically it treat.
Further, operator can also increase business generic parameter in service priority table, specifically can refer to
Table 3.
Table 3
Operator refers to business generic parameter and IPP_S and DP_S is preset.It is assumed that in Streaming Media class
In the case that the significance level of not corresponding business is higher than business corresponding to other classs of service, it is corresponding that streaming class can be set
Business IPP_S be higher than business corresponding to other classs of service IPP_S, the DP_S of business is less than corresponding to streaming class
The DP_S of business corresponding to other classs of service.Such as due to RTSP (Real Time Streaming in table 3
Protocol, real time streaming transport protocol) the affiliated class of service of video traffic is streaming class, therefore presets RTSP videos
The IPP_S of business is higher than the IPP_S of wechat, and the DP_S of RTSP video traffics is less than the DP_S of wechat.
It should be noted that operator can according to corresponding to actual conditions division business business generic.For example, operation
Wechat delineation of activities can be background classification according to actual conditions by business, by wechat delineation of activities can also be it according to actual conditions
Its business generic, is not limited herein.Wherein, other business generics include interactive class, session classification
Etc..
In addition, it is necessary to explanation, how excellent to business IP according to the business generic parameter of business in the present invention
First level value IPP_S and business packet loss priority value DP_S do advance setting and not limited.
Further, the service identification parameter in table 1 can also be changed by the title of business in service priority table
Into the ID number of business, as shown in table 4.
| Service identification | Business IP precedence value IPP_S | Business packet loss priority value DP_S |
| 1001 | 5 | 0 |
| 1002 | 4 | 1 |
| 1003 | 3 | 2 |
| 1004 | 2 | 3 |
Table 4
It should be noted that the ID number that the business of the entitled wechat in table 1 corresponds in table 4 is 1001, it is entitled
ID number corresponding to mobile phone QQ business is 1002, and ID number corresponding to the business that an entitled sudden peal of thunder is downloaded is 1003, entitled Baidu
ID number corresponding to the business of map is 1004, what deserves to be explained is ID number corresponding to wechat business must be not necessarily 1001,
Can be numeral 1, or by other numerals, as long as business different in the present invention has different ID numbers, not to industry
ID number in business mark is limited using which numeral.
In step 201, it is acquiescence class by the data packet recording when DPI is unidentified goes out service identification corresponding to packet
Type.
Wherein, DPI not can recognize that business corresponding to packet includes two kinds of different situations.
A kind of situation is that DPI can only recognize class of service corresponding to packet and can not identify tool corresponding to the packet
Body business, such as DPI can identify that class of service corresponding to packet is streaming media service classification, and can not identify the data
Specific business is any in streaming media service classification corresponding to bag.Another situation is that the equal None- identifieds of DPI go out packet
Affiliated class of service and specific business.Also give in the present invention for the acquiescence industry corresponding to the packet of default type
Business priority list.As shown in table 5.
| Business generic | Class of service IP precedence value IPP_S | Class of service packet loss priority value DP_S |
| None- identified | 0 | 0 |
| Interaction | 4 | 1 |
| Streaming Media | 3 | 2 |
| Background | 2 | 3 |
Table 5
When DPI not can recognize that business corresponding to packet, after step 201, in addition to PGW obtains acquiescence business
IPP_S corresponding to class of service and DP_S in priority list.It is understood that now IPP_S represents that class of service IP is preferential
Level value, DP_S represent class of service packet loss priority value.
Wherein, in table 5, interaction, Streaming Media, background are all business generic.Such as wechat business, mobile phone QQ business
Belong to background classification, and RTSP video traffics belong to streaming class.
It should be noted that the different demands of class of service are come in advance to the priority of class of service according to operator
Carry out different settings.Table 5 can only be directed to different classs of service and carry out different priority level initializings.
203, PGW obtain the QCI of packet carrying.
Carrying IP precedence value IPP_B and carrying packet loss corresponding to QCI are preferential in 204, PGW acquisition QCI mapping tables
Level value DP_B.
It should be noted that the QCI mapping tables of this step can be as shown in table 6.
| Service quality rating identifies QCI | Carry IP precedence value IPP_B | Carry packet loss priority value DP_B |
| 1 | 5 | 0 |
| 2 | 4 | 1 |
| 3 | 3 | 2 |
| 4 | 2 | 3 |
Table 6
It should be noted that table 6, which can be directed to different QCI, sets different carrying IP precedence value IPP_B and carrying
Packet loss priority value DP_B.
Wherein, it is excellent that QCI, carrying IP precedence value IPP_B, carrying packet loss are illustrate only in the QCI mapping tables in table 6
First tri- parameters of level value DP_B, but these parameters are not limited to, such as can also increase in QCI mapping tables resources-type
The parameters such as type, business citing.Specific parameter is not limited in the present invention.
The carrying IP precedence value IPP_B of acquisition is designated as IPP_B in QCI mapping tables, carries packet loss priority
Value DP_B is designated as DP_B.
205, PGW by IPP_S, IPP_B and DP_S, DP_B, and IP precedence value IPP and the packet loss for calculating packet are preferential
Level value DP.
Specifically include：
First, the final IP precedence value IPP of packet is obtained by IPP_S and IPP_B.Computational methods are as follows,
1. as IPP_S and IPP_B equal, IPP IPP_B；
2. when IPP_S is more than IPP_B, IPP is that IPP_B adds 1；
3. when IPP_S is less than IPP_B, IPP is that IPP_B subtracts 1.
Secondly, the final packet loss priority value DP of packet is obtained by DP_S and DP_B.Computational methods are as follows,
1. as DP_S and DP_B equal, DP DP_B；
2. when DP_S is more than DP_B, DP is that DP_B adds 1；
3. when DP_S is less than DP_B, DP is that DP_B subtracts 1.
206, PGW the IP precedence value IPP of obtained packet and packet loss priority value DP be calculated it is specific
