Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The schematic flow sheet of the base station identification approach that Fig. 1 provides for the embodiment of the invention one, this method can be carried out by deep-packet detection DPI (the Deep packet Inspection) equipment of disposing in the 3G network, and as shown in Figure 1, this method comprises:
Step 100, receiving remote subscriber dialing authentication request RADIUS message;
In the practical application, authentication request RADIUS message that can be when monitoring mode that packet data serving node PDSN (Packet Data ServiceNode) sends to the RADIUS message of authentication and authorization charging AAA (Authentication Authorization Accounting) server and obtain the user and insert.Can also receive the authentication request RADIUS message of the RADIUS message of making a copy for behind the RADIUS message that PDSN sends to DPI equipment when obtaining the user and inserting by aaa server.Usually carry the attribute (Attribute) of the radius protocol regulation of some in the RADIUS message, for example information such as user name, password, IP address.Because radius protocol has favorable expansibility, the increase of therefore new attribute can not have influence on the realization of existing protocol.
Step 105 obtains the cell information that described user inserts the sub-district by first radius attribute of resolving in the described RADIUS message, comprises sub-district ID in the described cell information;
Need to prove that 3GPP that first radius attribute in the embodiment of the invention is meant or 3GPP2 be to the attribute that is used for the identifying user positional information of radius protocol expansion, customer position information is meant sub-district and the base station information in the network that the user inserts usually.For example, in the WCDMA network, 3GPP is customer position information (3GPP-User-Location-Info) attribute to the attribute that is used for the identifying user positional information of radius protocol expansion, in the 3GPP-User-Location-Info attribute, has comprised sub-district and base station information that the user inserts; In the CDMA2000 network, 3GPP2 is sub-district id information (3GPP2-BSID) attribute or subnet information (3GPP2-Subnet) attribute to the attribute that is used for the identifying user position of radius protocol expansion, wherein, the 3GPP2-BSID attribute is used for identifying the sub-district and the base station information of CDMA20001x network, and the 3GPP2-Subnet attribute is generally used for identifying sub-district and the base station information in the CDMA20001xEV-DO network.
Because distinct device is used for the coded system of identifying cells and base station information in first radius attribute may be different, be not sub-district and base station information to be identified at first radius attribute in strict accordance with the coded system of 3GPP or 3GPP2 regulation, therefore, in the embodiment of the invention by the first radius attribute identifying cells in the RADIUS message, the field of base station information are resolved, handle as sub-district ID resolving the property value unification that obtains, processing mode is more easy.
Step 110 obtains the base station IDs of described user's access base station according to the corresponding relation of described sub-district ID and default sub-district ID and base station IDs.
Concrete, the corresponding relation of sub-district ID and base station IDs can use the management information of base station equipment to set in advance in the network according to this user's access, wherein set the property value of field in first radius attribute (comprising 3GPP-User-Location-Info, 3GPP2-BSID or 3GPP2-Subnet attribute) that sub-district ID reports for each base station equipment, base station IDs can have nothing in common with each other according to the configuration of each office point, as long as guarantee in the whole network unique.
Be understandable that in the process of networking, the base station equipment of using in the network of each office point to its operation is predicted, therefore the corresponding relation of sub-district ID and base station IDs can be set according to the management information of the base station equipment of using.Therefore, after the described user of acquisition inserts the sub-district ID of sub-district, can directly obtain the base station IDs of this user's access base station, identify the base station that the user inserts according to the corresponding relation of sub-district ID default in this network and base station IDs.
The embodiment of the invention is by when user access network, the sub-district that is used for the network that identifying user inserts in the remote customer dialing authentication request RADIUS message that receives and the attribute of base station information are resolved, the property value that obtains is inserted the sub-district ID of sub-district as the user, and obtain the base station IDs of user's access base station with the corresponding relation of base station IDs, thereby identify network traffics affiliated sub-district and base station information according to default sub-district ID.Since in the present embodiment by resolving after first radius attribute in the RADIUS message obtains the user and insert the sub-district ID of sub-district, it is the base station IDs that obtains user's access base station according to the corresponding relation of default sub-district ID and base station IDs, and the corresponding relation of sub-district ID and base station IDs can be provided with in advance according to the management information of the base station equipment in the network of user's access, even therefore each equipment in first radius attribute to each sub-district, the coded system difference of base station information, do not need to obtain sub-district ID and base station IDs by adopting different analysis modes according to different coded systems yet, processing mode is simply effective, and system is easy to safeguard.
The schematic flow sheet of the base station identification approach that Fig. 2 provides for the embodiment of the invention two, as shown in Figure 2, this method comprises:
As described in above-mentioned embodiment, in the practical application, authentication request RADIUS message that can be when monitoring mode that packet data serving node PDSN (Packet Data Service Node) sends to the RADIUS message of authentication and authorization charging AAA (AuthenticationAuthorization Accounting) server and obtain the user and insert.Can also receive the authentication request RADIUS message of the RADIUS message of making a copy for behind the RADIUS message that PDSN sends to DPI equipment when obtaining the user and inserting by aaa server.
Wherein, second radius attribute is the radius attribute that is used for the marked network type in the RADIUS message.For example, the 3GPP-RAT-TYPE attribute that second radius attribute can carry for the RADIUS message, the 3GPP-RAT-TYPE attribute is the wireless access network RAN type that is used for identifying subscriber terminal of 3GPP expansion, can be used to discern the 3G network type.Concrete, can determine the network type of user access network by the 3GPP-RAT-TYPE property value, for example, set the 3GPP-RAT-TYPE property value and be 0 and represent that network type is WLAN; The 3GPP-RAT-TYPE property value is that 2000 marked network types are CDMA2000_1X or the like, narrate no longer one by one at this, when the 3GPP-RAT-TYPE property value in the RADIUS message that receives is 2000, can determine that the network that this user inserts is the CDMA2000_1X network according to the corresponding relation of 3GPP-RAT-TYPE property value that is provided with and network type.
In addition, second radius attribute can also specifically be set according to the office point demand, for example, also can directly sign there be the recognition property of the radius attribute of cell information as network type, for example, 3GPP-User-Location-Info attribute in the RADIUS message that can directly base station equipment be sent is as the recognition property of WCDMA network, with the recognition property of the 3GPP2-BSID in the RADIUS message as the CDMA2000_1X network, the types of network equipment of discerning the user with the 3GPP2-Subnet attribute is C net CDMA2000 1x EV-DO equipment or the like, certainly, if there is other RADIUS extended attribute of new network using to carry out network identity, also the network identity attribute that this new network can be introduced is as second radius attribute, limit no longer one by one at this, can identify network type in the present networks by second radius attribute as long as guarantee.
Need to prove, the TD-SCDMA network is the same with the WCDMA network also to be based on the 3G network that the G net grows up, in the identification of base stations of this network, also can discern sub-district and the base station information that the user inserts by the 3GPP-User-Location-Info attribute in the RADIUS message of base station equipment transmission.
Concrete, in actual applications, second radius attribute that can be directly may relate to according to the network equipment situation of using in the network writes in the DPI equipment with corresponding network type, when DPI equipment receives the RADIUS message, judge that according to second radius attribute in the RADIUS message that is received its corresponding network type gets final product.Yet when adopting this mode, if newly-increased in the network that the office point is administered have a new network type, when this new network type adopts the second new radius attribute to discern, need carry out upgrading processing to whole DPI equipment, system maintenance is not too convenient.
Further, for better system maintenance easy, the corresponding relation of the second radius attribute information and network type can be handled by the form of configuration file, concrete, when DPI equipment receives the RADIUS message of base station equipment transmission, need can obtain which the second radius attribute information of identification by the form that reads configuration file, thereby judge the corresponding network type of second radius attribute that from the RADIUS message, recognizes according to the second radius attribute information in the configuration file and the corresponding relation of network type.For example, configuration file can include as the second radius attribute information in the following table one and the corresponding relation of network type:
| The 2nd RAIUS attribute | Network type |
| 3GPP-User-Location-Info | WCDMA |
| 3GPP2-BSID | CDMA20001x |
| 3GPP2-Subnet | CDMA20001x?EV-DO |
| 3GPP-RAT-TYPE(2000) | CDMA20001x |
| 3GPP-RAT-TYPE(0) | WLAN |
| .... | .... |
(table)
Concrete, include the corresponding relation of the network type and the first radius attribute information in described first configuration information.As described in above-mentioned embodiment, 3GPP that first radius attribute in the embodiment of the invention is meant and 3GPP2 comprise 3GPP-User-Location-Info, 3GPP2-BSID or 3GPP2-Subnet attribute etc. to the sub-district of the network that is used for the identifying user access of radius protocol expansion and the attribute of base station information.
Wherein, the corresponding relation of the network type and the first radius attribute information can preestablish according to the management information of the base station equipment of using in the Home Network, and this corresponding relation can be represented by the form of tabulation.For example, can be shown in following table two:
(table two)
For example, when the network of the described user's access of identification is the WCDMA network, can determine that from the corresponding relation of the above-mentioned network type and the first radius attribute information 3GPP-User-Location-Info attribute in this RADIUS message is first radius attribute, promptly need to obtain the sub-district id information that this user inserts the sub-district by the 3GPP-User-Location-Info attribute in this RADIUS message is resolved.
Further, as shown in Table 2, in the corresponding relation of the described network type and the first radius attribute information, can also comprise the more specific location information of cell information in first radius attribute, just, the value of this field is inserted the sub-district ID of sub-district as the user in order to obtain the concrete field in first radius attribute that sub-district ID that this user inserts the sub-district need resolve.For example, when the network of the described user's access of identification is the WCDMA network, determine that according to the corresponding relation of the described network type and the first radius attribute information needs obtain the sub-district id information by the 3GPP-User-Location-Info attribute in this RADIUS message is resolved, the particular location of this sub-district id information in the 3GPP-User-Location-Info attribute is that the 5th byte begins, length is 7 bytes, the coded system that this id information adopts is the coding form of decimal system DEC, that is to say, obtain the sub-district ID that this user inserts the sub-district by the value of resolving 5-12 byte field in the 3GPP-User-Location-Info attribute in this RADIUS message.
Handle similar with the corresponding relation of above-mentioned steps 205 described second radius attribute information and network type by the form of configuration file, in concrete the application, for system maintenance easy, the corresponding relation of the network type in this step and the first radius attribute information also can be handled by the form of configuration file.When the network type of the described user access network of DPI recognition of devices, can obtain first radius attribute that needs are resolved according to the mode that reads configuration file.
Step 215 is resolved described first radius attribute, obtains the sub-district ID that described user inserts the sub-district;
Concrete, can resolve according to the field of setting first radius attribute that the needs that get access to are resolved, will resolve the property value of acquisition as sub-district ID.For example, when the network of user's access is the WCDMA network, will resolve the property value that obtains inserts the sub-district as this user sub-district ID to the field of 5-12 byte in the 3GPP-User-Location-Info attribute in the RADIUS message; When the network of user's access is the CDMA20001x network, will resolve the property value that obtains inserts the sub-district as the user sub-district ID to the field of 0-12 byte in the 3GPP2-BSID attribute in the RADIUS message.
Need to prove, in the 3GPP-User-Location-Info attribute, according to the expansion of 3GPP to radius protocol, the field of 5-12 byte is cell information identification CGI (Cell Globe Identity) field in the 3GPP-User-Location-Info attribute, this field is used for identifying cells and base station IDs information, the international code form of this field is: MCC+MNC+LAC+CI, and wherein MCC+MNC+LAC is used to identify base station IDs, and MCC+MNC+LAC+CI is used for identifying cells ID.Because distinct device may be different to the coded system of CGI field, therefore in the present embodiment, unified property value with the CGI field in the 3GPP-User-Location-Info attribute is as sub-district ID, and the coded system that need not distinguish distinct device adopts different analysis modes to resolve, and processing mode is more easy.
Same, according to the expansion of 3GPP2 to radius protocol, the 3GPP2-BSID attribute is totally 12 bytes, all are the fields that are used to deposit sub-district and base station information, yet, because distinct device may be different to the coding of this section byte, therefore, according to the prior art scheme, need adopt different analysis modes from this field, to parse sub-district ID and base station IDs at the coded system of distinct device, in the embodiment of the invention, with this 3GPP2-BSID attribute the property value unification of totally 12 bytes insert the sub-district ID of sub-district as this user, processing mode is more easy.
Step 220 obtains the base station IDs of described user's access base station according to the corresponding relation of the sub-district ID that obtains and default sub-district ID and base station IDs.
Concrete, the mapping relations of sub-district ID and base station IDs can use the management information of equipment to set in advance in the network according to this user's access, wherein set the property value of field in sub-district ID 3GPP-User-Location-Info, 3GPP2-BSID that can report for each base station equipment or the 3GPP2-Subnet attribute, base station IDs can have nothing in common with each other according to the configuration of each office point, as long as guarantee in the whole network unique.
Be understandable that in the process of networking, the base station equipment of using in the network of each office point to its operation is predicted, therefore the corresponding relation of sub-district ID and base station IDs can be set according to the management information of the base station equipment of using.Therefore, after the described user of acquisition inserts the sub-district ID of sub-district, can directly obtain the base station IDs of this user's access base station, identify the base station that the user inserts according to the corresponding relation of sub-district ID default in this network and base station IDs.
Further, when base station equipment in the network is upgraded the new equipment that the new base coded mode of employing is arranged, can upgrade the corresponding relation of corresponding relation, network type and the first radius attribute information of above-mentioned second radius attribute information and network type and the corresponding relation of sub-district ID and base station IDs according to the management information of new base station equipment, set the sub-district ID that the property value of field is administered as this equipment in first radius attribute that new equipment is reported, for it base station IDs that has uniqueness accordingly is set simultaneously.This shows, when increasing the base station equipment that the different coded system of employing is arranged in the network newly, need not to develop again new analysis mode, only need to upgrade corresponding corresponding relation and can obtain described sub-district of network traffics and base station information, system maintenance is simple, and maintenance cost is low.
The embodiment of the invention is by the corresponding relation according to default second radius attribute information of the management information of the base station equipment of using in the network and network type, the corresponding relation of the corresponding relation of the network type and the first radius attribute information and sub-district ID and base station IDs, when receiving the RADIUS message, judge the network type of this user access network according to the corresponding relation of second radius attribute information that disposes and network type, and determine first radius attribute that needs are resolved according to the corresponding relation of the network type that identifies and the default network type and the first radius attribute information, and obtain the sub-district id information that the user inserts the sub-district by resolving first radius attribute, again according to the base station IDs of the sub-district ID that is provided with the corresponding relation acquisition user access base station of the corresponding relation of base station IDs.Therefore, this method need not to develop different analysis modes in advance according to the sub-district of concrete vendor equipment in first radius attribute, the coded system of base station information, can obtain sub-district ID and base station IDs information, processing mode is simple, and goes in the multiple network system.Simultaneously because present embodiment preserves above-mentioned corresponding relation in the mode of configuration file, when network type change or network system in equipment when changing, upgrading corresponding configuration information gets final product, and need not carry out system upgrade comprehensively, be easy to safeguard that maintenance cost is lower.
On the basis of the foregoing description, the embodiment of the invention provides a kind of method for controlling network flow again, and this method can be used in the device that is used for the Control Network flow in the network, for example DPI equipment.As shown in Figure 3, the schematic flow sheet of the method for controlling network flow that Fig. 3 provides for the embodiment of the invention three, this method comprises:
Step 300 receives the RADIUS message;
Step 305 obtains the cell information that described user inserts the sub-district by first radius attribute of resolving in the described RADIUS message, comprises sub-district ID in the described cell information;
Step 310 obtains the base station IDs of described user's access base station according to the corresponding relation of described sub-district ID and default sub-district ID and base station IDs;
Step 315 is controlled described user's flow according to the described sub-district ID that obtains and/or base station IDs and default network traffics control strategy.
Concrete, above-mentioned steps 300-step 310 can not repeat them here referring to above-mentioned embodiment about base station identification approach.After identifying the sub-district ID and base station IDs information that the user inserts the sub-district, after the user inserted Internet, DPI equipment can be controlled described user's flow according to default network traffics control strategy.Concrete, DPI equipment can issue control command to this user according to the flow control strategy to this sub-district and/or base station user preset, and this user's flow is controlled.For example, user's flow can not surpass 1M/s in setting the A sub-district, if user B inserts this A sub-district, and party B-subscriber's present flow rate surpassed 1M/s, then can carry out current limliting or packet loss processing to the flow of user B according to default control strategy.Certainly, be understandable that, can only control this user's flow according to the flow control strategy of concrete sub-district, also can control this user's flow, thereby reach the purpose that the flow of this sub-district and/or base station is controlled according to the flow control strategy of base station under this sub-district and this sub-district.
For the method for controlling network flow in the clearer description embodiment of the invention, Fig. 4 provides the described method for controlling network flow application scenarios of an embodiment of the invention figure, and as shown in Figure 4, this method comprises:
Step 400, network manager issue the control strategy of sub-district in the present networks, base station flow in advance to DPI equipment;
Step 405, the user initiates the access request of accesses network Internet to PDSN;
Step 410, PDSN sends authentication request packet to aaa server, and the request aaa server authenticates this user;
Step 415, aaa server is to the DPI equipment authentication request packet that PDSN sends of making a copy for;
Step 420, DPI device parses RADIUS message obtains the sub-district ID that the user inserts the sub-district, and obtains the base station IDs of described user's access base station according to the corresponding relation of default sub-district ID and base station IDs;
Concrete, this step can not repeat them here referring to above-mentioned embodiment about base station identification approach.
Step 425 when AAA passes through described authentification of user, is passed through message to the PDSN return authentication;
Step 430, when authentification of user when inserting the Internet network, user's the network traffics DPI equipment of flowing through;
Step 435, DPI equipment is controlled this user's flow according to default sub-district, base station flow control strategy to this user's access;
Be understandable that, owing to also carry user's identity information in the RADIUS message, therefore after utilizing above-mentioned base station identification approach to identify the base station IDs that this user inserts the sub-district ID of sub-district and user's access base station, when this authentification of user passes through the back access network, sub-district ID, the base station IDs that user's identity information and this user can be inserted the sub-district are bound, the user is issued control command, to reach the purpose that this user's flow is controlled.
Step 440, the flow after the DPI Equipment Control enters the Internet network, thereby reaches flow control to whole network by the purpose to customer flow control.
