Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Fig. 2 has described mobile data processing function provided by the invention.Wherein 100 be the original processing capacity of Home eNodeB, it carries out layering for mobile data handles, the protocol data of each layer, and all in protocol layer resume module independently, the collaborative Home eNodeB function of finishing of each layer.200 are mobile Data Detection function, the data that Home eNodeB is handled, comprise the up mobile data of mobile terminal device transmission and the descending mobile data that mobile network appliance sends, these data will be via household base station device, being sent to the destinations traffic end handles, perhaps end at household base station device, its destinations traffic place is Home eNodeB.These data detect by 200, and being defined as target data also is non-target data.300 are data processing function, by selecting the suitable data process points, obtain target data and carry out the data processing.
The present invention finishes Data Detection and the processing of Home eNodeB by data processing function 300 and Data Detection function 200, and Fig. 3 has described the basic process of Data Detection and processing.Namely
Step 200 is carried out data measuring ability 200, and this step determines whether current mobile data are target data, carries out which kind of data and handles.By analyzing the service attribute of family's base station data, as concrete class of service, mobile terminal identification etc., and by the data processing policy analysis based on these service attributes, as the data processing configuration is arrived destination mobile terminal, non-target terminal does not need to carry out target data to be handled; Or with the data processing configuration to concrete professional, non-target service does not need to carry out target data and handles.By Data Detection as above, whether need data handle, and carry out various data processing methods if both can judge current mobile data.
Handle because Home eNodeB carries out layering for mobile data, the protocol data of each layer is all in protocol layer resume module independently.The protocol layer of Home eNodeB is handled, and attribute data and the load data of equivalent layer agreement can be provided, and the protocol attribute data may comprise simple service attribute, and the agreement load data then needs to carry out pre decoding, obtains more service attribute content.The present invention can provide a kind of data detecting method, and namely the method for protocal analysis is obtained the protocol attribute data, searches the service attribute data in the protocol attribute data, can also pass through the method to the pre decoding of agreement load data, obtains the more business attribute.The invention provides a kind of method, i.e. pre decoding successively, agreement load itself also is the protocol data of a multilayer, parsing to these agreements, from outside to inside, successively resolve as required, the degree of depth of agreement load pre decoding can change according to the actual requirements, the degree of depth of preanalysis is more dark, and the service attribute content of obtaining is also abundant.For example as in the IUH of TDSCDMA Home eNodeB agreement, parsing to RANAP, current mobile data be can get access to and packet domain or circuit domain belonged to, can also judge simultaneously the current circuit domain business existence that whether has, the NAS load of carrying in can also be to RANAP under the situation that circuit domain business exists is carried out degree of depth pre decoding, can get access to the short message service of circuit domain, and other circuit domain business.
The present invention also provides a kind of method, can initiatively initiate extra agreement flow process, the protocol data that gets access in the extra flow process is detected, obtain attribute data and the load data of equivalent layer agreement, the protocol attribute data may comprise simple service attribute, the agreement load data then needs to carry out pre decoding, obtains more service attribute content.These extra agreement flow processs do not belong to original handling process of Home eNodeB, but contain abundant service attribute content, therefore can with these portable terminals or mobile network's agreement flow process be placed on Home eNodeB inside, be used for initiatively initiating operation flow, analyze data to obtain extra detection.For example as in the TDSCDMA Home eNodeB, sometimes only can't get access to the sign of UE by the agreement of UU mouth and IUH mouth, as IMSI/IMEI, and these signs are very crucial for Data Detection, therefore can introduce extra NAS TD mobile phone logo obtains flow process, to obtain the TD mobile phone logo
Handle because Home eNodeB carries out layering for mobile data, the protocol data of each layer is all in protocol layer resume module independently.The invention provides a kind of method of obtaining data, can choose suitable protocol layer as the Data Detection point.Choose the suitable data test point, can obtain the more service attribute data of horn of plenty, and choose inappropriate Data Detection point, then can not obtain effective service attribute data.The present invention also provides a kind of method, can obtain the protocol data of a plurality of protocol layers, is used for Data Detection, and the protocol data of a plurality of protocol layers is carried out Data Detection, can obtain more information.The present invention also provides a kind of Data Detection point, can initiatively initiate extra agreement flow process.By these extra agreement flow processs, can obtain more mobile data.For example as in the TDSCDMA Home eNodeB, can choose RANAP module among the IUH as the protocol data test point, by the detection to the RANAP data, get access to the current business in Home eNodeB of TD mobile phone, as video call.
The method of the present invention by providing data processing policy to select makes that obtaining of target data is more flexible.Data processing policy is used for judging whether current mobile data need to do data and handle.The present invention determines that by policy module whether which kind of data being current mobile data carried out handles by with the input of service attribute as policy module.The invention provides a kind of method of data processing policy flexibly, policy configurations is arrived different mobile data.Make different mobile data obtain different data processing methods.The difference here can be the difference of the concrete type of service that comprises in the mobile data, also can be the difference of the portable terminal under the mobile data.Therefore can be with policy configurations to destination mobile terminal, non-target terminal does not need to carry out data to be handled; Also can be with policy configurations to the objectives business, non-target service does not need to carry out data and handles; Also various strategy combinations can be carried out specific data and are handled.Total data can certainly be carried out data as target data handles.For example as in the TDSCDMA Home eNodeB, can the configuration data processing policy, as the sign to specific TD mobile phone, as IMSI/IMEI, carry out the note bypass and handle, when the specific IMSI/IMEI mobile phone that detects configuration when the family base station carries out short message service, then note is carried out bypass and handled.
Step 300, carry out target data processing capacity 300, this step will be chosen the suitable data process points, on the data process points, can get access to target data, change target data simultaneously in original processing of Home eNodeB, add new data and handle, concrete data processing is different because of different data processing methods.
Handle because Home eNodeB carries out layering for mobile data, the protocol data of each layer is all in protocol layer resume module independently.The invention provides a kind of method of obtaining data, choose suitable protocol layer as the data process points.Choose the suitable data process points, can effectively obtain target data and carry out specific target data processing.In the TDSCDMA Home eNodeB, can choose RANAP as the data process points of note, choose the IUUP agreement as the data process points of voice and video.Choose the GTP agreement as the data process points of block domain data.And for simulation process, then need to select with a plurality of protocol layers as the data process points, as when the analog network side apparatus, select institute's protocols having of entire I UH protocol suite, as the data process points.
The invention provides the data processing method of simulation, this mode has stopped the original processing of target data at Home eNodeB, simultaneously target data is simulated, after the simulation process, may export new mobile data, can open new processing to these data at data process points Home eNodeB; Home eNodeB is handled in the data of data process points and has been terminated, and after data were finished dealing with, simulation process can produce new mobile data, opened new processing at Home eNodeB.Analog form has changed the direction of data flow, has shielded the destinations traffic side of mobile data fully.In the TDSCDMA Home eNodeB, the data redirection of eating dishes without rice or wine that the TD mobile phone can be sent is to the network equipment of simulating, and the network equipment reception data from simulating, and gives TD mobile phone by eating dishes without rice or wine, and for the data that are redirected, destination network device then can't obtain.Wired mouthful of data redirection network equipment can also being sent is to the cell phone apparatus of simulation, and the cell phone apparatus reception data from simulating, and gives network equipment by wired mouth, and for the data that are redirected, target TD mobile phone then can't obtain.
The invention provides the data processing method of monitor bypass, this monitor bypass mode is at the copy of data process points increase to target data, increase is handled the bypass of copies data, and target data keeps original processing constant, unaffected in the data process points simultaneously.Monitor bypass mode provided by the invention can not change the direction of data flow, handles branch but increased a bypass, therefore can not influence mobile data at data flow and the data content of sources traffic end and destinations traffic end.In the TDSCDMA Home eNodeB, monitor for note, then be to choose RANAP as the data process points, for the short message content that captures, after copying, send to note monitoring service processing module and carry out Business Processing.
The invention provides the data processing method of modification, this data process points that is modified in has been suspended the original processing of target data at Home eNodeB, and to the target data processing of making amendment, after target data is modified and finishes, can recover the processing in the target data of data process points; Home eNodeB has been suspended in original processing of data process points, and after data were finished dealing with, original processing had been resumed, but change has taken place the content of target data at this moment.Alter mode provided by the invention can not change the direction of data flow, but has revised the content of target data, and the mobile data that the mobile data homology communication ends that makes the destinations traffic end receive sends are compared, and change has taken place content.In the TDSCDMA Home eNodeB, revise for note, be to choose RANAP as the data process points equally, when capturing short message service, suspend the short message service flow process, after short message content is copied, send to note modification Service Processing Module and carry out Business Processing, amended short message content sends back to the data process points again, then recovers the short message service flow process, and amended short message content is sent to the target place.
Therefore by step 200 and step 300, can finish Data Detection and processing based on Home eNodeB.
Below step 200 and 300 is done specific descriptions.
As Fig. 4, be the flow chart that target data is selected.
Wherein step 201 is and obtains protocol data, and analyzes the acquisition service attribute.Service attribute is used for the input of data processing policy, therefore when obtaining enough service attributes, can correctly find data processing method according to the data processing policy that disposes in advance.If can't obtain enough service attributes, then can't correctly carry out data processing policy, also just can't obtain concrete data processing method.These service attributes can be customized.In the TDSCDMA Home eNodeB, these service attributes can be TD mobile phone logo IMSI/IMEI, type of service identification packet territory note/circuit domain note/video call/audio call/packet switch domain service etc.
Step 202 judges namely whether service attribute is enough, if satisfy the input demand of data processing policy, then direct execution in step 204 if service attribute is not enough, can not satisfy the input demand of policy module, then also needs to continue to obtain service attribute.In the TDSCDMA Home eNodeB, the type of service sign will can get access to target data by continue protocol data is detected, as to short message service, then need the NAS PDU to RANAP that continues to carry out pre decoding, filter non-target NAS PDU, up to the NAS PDU that takes out note.
Step 203, namely obtain service attribute by extra agreement flow process, these extra agreement flow processs do not belong to original handling process of Home eNodeB, but contain abundant service attribute content, therefore these portable terminals or mobile network's agreement flow process can be placed on Home eNodeB inside, initiatively initiate operation flow, to obtain extra analysis data, obtain service attribute then.In the TDSCDMA Home eNodeB, the sign of TD mobile phone is TMSI/PTMSI sometimes, and need go to obtain the IMSI/IMEI sign of TD mobile phone this moment by extra NAS flow process.
Step 204, be that data processing policy is selected module, its input is service attribute, output is concrete data processing method, as pass through preceding step, obtaining the service attribute of mobile data---target terminal sign according to this target terminal sign, can find the concrete data processing method that is configured on this target terminal sign.To concrete service attribute, the mobile data of non-service attribute then do not need data to handle with the data processing configuration.The data processing policy module can dispose in advance or on-the-fly modify.
Fig. 5 is the particular flow sheet of analog form.
Step 301 is namely selected the data process points, handles because Home eNodeB carries out layering for mobile data, and the protocol data of each layer is all in protocol layer resume module independently.The invention provides a kind of method of obtaining data, choose suitable protocol layer as the data process points.Choose the suitable data process points, can effectively obtain the target data that needs and carry out specific target data processing.In the TDSCDMA Home eNodeB, as when the analog network side apparatus, select institute's protocols having of entire I UH protocol suite, as the data process points.
Step 302 namely stops mobile data in original processing of Home eNodeB, and simulation has stopped the original processing of target data at Home eNodeB, and fully shielded the destinations traffic side of mobile data because mobile data no longer are sent to destinations traffic side this moment.In the TDSCDMA Home eNodeB, can be terminated from the data of network equipment, no longer be dealt into the TD mobile phone, but these data are carried out re-orientation processes, be sent to the analog service resume module.
Step 303 is namely carried out the business data processing of simulation, and what carry out here is the simulation behavior of mobile data, and it can simulate mobile network appliance or mobile terminal device.When the simulation mobile network, actual then conductively-closed of mobile network appliance; And when pseudo-terminal, then then conductively-closed of Shi Ji terminal equipment.The shielding here can also can be shadow shield for shielding fully.Shadow shield namely when mobile data are target service, need shield the destinations traffic side of reality, and other situations then do not need shielding.Full-shield then is that the whole business datums to destinations traffic side shield.In TDSCDMA Home eNodeB system, analog network side apparatus and simulation TD mobile phone are carried out specific analog service and are handled, the simulation behavior that certain analog network equipment and simulation TD mobile phone also can make up.
Step 304 judges namely whether simulation process has mobile data to produce, and namely simulation process also can produce mobile data, arrives sources traffic side via Home eNodeB, to reach the function that replaces destinations traffic side and sources traffic side communication.In TDSCDMA Home eNodeB system, after analog network side apparatus and simulation TD mobile phone are carried out specific analog service processing, may produce analogue data, send it back source side via Home eNodeB, to finish specific simulation process.
The particular flow sheet of Fig. 6 for revising
Step 321 is namely selected the data process points, handles because Home eNodeB carries out layering for mobile data, and the protocol data of each layer is all in protocol layer resume module independently.The invention provides a kind of method of obtaining data, choose suitable protocol layer as the data process points.Choose the suitable data process points, can effectively obtain the target data that needs and carry out specific target data processing.As in the TDSCDMA Home eNodeB, revise for note, be to choose RANAP as the data process points equally, need the NASPDU to RANAP that continues to carry out pre decoding, filter non-target NAS PDU, up to the NAS PDU that takes out note.
Step 322 has namely been suspended mobile data in original processing of Home eNodeB, finishes dealing with in data, receives amended target data, then has been resumed.As in the TDSCDMA Home eNodeB, when capturing short message service, suspend the short message service flow process, after short message content copied, send to note modification Service Processing Module and carry out Business Processing, amended short message content sends back to the data process points again, then recovers the short message service flow process, and amended short message content is sent to the target place.
Step 323 is namely carried out the Business Processing of revising, and what carry out here is the modification of mobile data, and change has taken place the content that makes data handle.Alter mode provided by the invention can not change the direction of data flow, but has revised the content of target data, and the mobile data that the mobile data homology communication ends that makes the destinations traffic end receive sends are compared, and change has taken place content.Concrete note is revised logic, can revise business demand by the note at scene and decide.
Step 324 has been recovered the original processing of target data at Home eNodeB
