Description
Technical field
The present invention relates to network element device, more specifically, relate to a kind of authentication method and system that is used for passive optical network Optical Network Terminal (ONT)/optical network unit (ONU).
Background technology
Because at EPON (PON, Passive Optical Networks) a common optical line terminal (OLT) passes through optical distribution network (ODN in the system, Optical DistributionNetwork) connects a plurality of ONT/ONU, generally there is 1: 32,1: 64 or 1: 128 etc., and each ONT/ONU represents by its certain unique identifier, for example, can pass through its Media Access Controlled in the EPON system) MAC, Medium Access Control) unique identification is come in the address, the GPON system can pass through sequence number (SN, Serial Number) come unique identification, no matter be connected to equal energy operate as normal under which branch of ODN at all ONT/ONU under the OLT PON, not limited its original branch optical fiber that distributes, and distributed bandwidth originally, type of service etc. are normally used too.
Thereby the ONT/ONU under same OLT PON mouth will not be subjected to the restriction in place, can arbitrarily move on other branch optical fibers, and its all business and bandwidth also follow mobilely, and operator does not wish so usually.If two ONT/ONU are arranged under certain PON mouth, one may be enterprise customer's (high bandwidth, professional abundant, be designated ONTx, place one), one is personal user's (low bandwidth, simple professional, but it may be used for some commercial objects, such as being used to out the Internet bar, be designated ONTy, place two), if the enterprise customer is charge methods such as monthly payment or Bao Nian, like this, the time that is on duty is placed on place one with ONTx, ONTy is placed on place two, coming off duty and the time at weekend, two ONT is exchanged, ONTx is placed on place two, and ONTy is placed on place one.
Thereby benefits of operators can suffer damage, and also seems unfair.In the industry cycle, also do not have a kind of unified processing method, may different manufacturers different treating methods be arranged with different operators for this kind situation.For so a kind of situation, for the authentication mode of common employing, for example, the mode of employing SN/MAC etc. or SN/MAC etc.+password can not authenticate this feelings, for such " illegally " user, also will think a kind of legal users.Thereby, need a solution to come ONT/ONU is authenticated.
Publication number is the method that has disclosed a kind of ONT/ONU of authentication in CN1855813 number the application for a patent for invention.In the method, come to compare by the positional information of obtaining user terminal (ONT/ONU) with this user self preposition information.If both differences are mated in certain predetermined difference value scope, think that then user terminal is a validated user, authentication success, otherwise think that user terminal is the disabled user, authentification failure.But this method has following shortcoming:
At first, its precalculated position information need be set, this value needs more accurate setting, and in engineering or in actual applications this value is not easy accurately to obtain.In addition,, in actual use, need constantly revise the consumer premise positional information, and be difficult to guarantee the correctness of the modification of this precalculated position information,, and be easy to cause erroneous judgement so operability is relatively poor in order the user not to be judged by accident;
Secondly, for the normally mobile user of actual needs, for example, after user's removal of home, still need to use its original terminal equipment (ONT/ONU), this moment, bigger variation took place in its actual range certainly, if according to this method, still original with it self precalculated position compares, and then is certain to cause erroneous judgement;
The 3rd, if certain user's branch optical fiber breaks down (for example, fibercuts etc.), need to change optical fiber; Perhaps, adopt this method, compare, erroneous judgement also can occur with its preposition information owing to aging the grade causes the actual distance of measuring that bigger variation etc. takes place.
Based on the shortcoming of above reason and existing method, need to propose a kind of new authentication method and solve the problems referred to above.

Whether the present invention mainly is in the PON system ONT/ONU being authenticated, adopting it legal apart from authenticating it.A table is set, comprises following field unique identifier (MAC/SN etc.) at least, distance, the corresponding record information of each ONT/ONU.After certain ONT/ONU reaches the standard grade, in this table, find the record of its correspondence according to its unique identifier (MAC/SN etc.), measure its distance then, compare with the distance of other records in this table, whether with other records in distance value equate, wherein the implication of Xiang Denging also comprise its error one more among a small circle in.If equated would judge this ONT/ONU be illegal and the distance of other History Logs all unequal then think legal.In addition, for the authentication of ONT/ONU, above distance authentication can combine together with other ONT/ONU information and authenticates, and all authentication items are by just success of back ONT/ONU authentication, if having one illegally, then thinks the ONT/ONU authentification failure.
Describe method of the present invention below with reference to the accompanying drawings in detail.
Fig. 1 is that as shown in Figure 1, this method may further comprise the steps according to the flow chart of the ONT/ONU authentication method in the PON of the present invention system:
Step S102 is provided with a table, and the sign of the one or more ONT/ONU under the PON and the current distance of one or more ONT/ONU are existed in the table with the form of record correspondingly;
Step S104 when each ONT/ONU reaches the standard grade, measures its actual range, and according to the record of searching in the table corresponding to ONT/ONU that is identified at of ONT/ONU;
Step S106, with the actual range that measures respectively with table in the current distance that is different from other records of record of ONT/ONU compare; And
Step S108, according to comparative result, whether ONT/ONU is legal in authentication.
Wherein, in step S108, when actual range is identical with the current distance of arbitrary record in other records, judge that then this ONT/ONU is illegal, determine authentification failure.Otherwise, when the current distance of the arbitrary record in actual range and other records is all inequality, judge that the distance of this ONT/ONU is legal.
After the distance of judging ONT/ONU is legal, can also may further comprise the steps: carry out other authentication; And behind other authentication success, judge that ONT/ONU is legal, and the current distance in will show is updated to actual range, otherwise under the situation of other authentification failure, ONT/ONU is illegal in judgement.
At this, identical can be understood as of current distance of arbitrary record in actual range and other records: the current distance of the arbitrary record during actual range writes down with other is identical, or identical in the predictive error scope.
In addition, the method according to this invention can also comprise the step of initial table: initial table is initialized as zero with the current distance of one or more ONT/ONU; And when each ONT/ONU reaches the standard grade, will be updated to the actual range that measures corresponding to the current distance of the sign of each ONT/ONU.
Fig. 2 is that as shown in Figure 2, detailed process is as follows according to the flow chart of the ONT/ONU authentication method in the PON system of the embodiment of the invention:
Under each PON, preserve a table, as shown in table 1.
| ONU?ID | Unique identifier | Distance | Other |
Table 1 ONT/ONU distance table
In the table shown in the table 1, the current distance of storing this ONU correspondingly with the unique identifier of each ONU.When initialization, current distance is initialized as zero.When each ONU reaches the standard grade, will be updated to the actual range that measures corresponding to the current distance of the sign of each ONU.In this table, unique identifier is MAC (Media Access Controlled) or SN (sequence number) etc.
As shown in Figure 2, when ONT/ONU reaches the standard grade, can get access to its unique identifier (MAC/SN etc.), find its corresponding record in the ONT/ONU table, the distance in writing down with other then compares, if the distance that is compared in the record is 0, then need not compare, represent unequal.If with one relatively the distance in the record equate then the ONT/ONU that represents just to have reached the standard grade is illegal, if it is unequal with the distance in the current relatively record, then continue relatively other records, up to the record of all other ONT/ONU in distance all unequal, think that then its distance is for legal.Continue to verify other then,, think that then this ONT/ONU is legal, authentication success if other items that need verify are all legal; Use the more former distance value in the new record of current distance value then.There is one if desired in Ren Zheng the project illegally, thinks that then ONT/ONU is illegal, authentification failure.
When if distance is illegal, can also report an alarm notification to webmaster, so that webmaster can in time be found moving of ONT/ONU.
The distance of all ONT/ONU can guarantee in engineering construction that each branch optical fiber does not wait, and has certain difference with each branch optical fiber consciously.In addition, equal implication in the method also comprise its error one more among a small circle in, and this small range can be carried out small adjustment by webmaster.
Fig. 3 is the block diagram according to the ONT/ONU Verification System 300 in the PON of the present invention system.As shown in Figure 3, this device comprises: unit 302 is set, is used to be provided with a table, and the sign of the one or more ONT/ONU under the PON and the current distance of one or more ONT/ONU are recorded in the table with the form of record correspondingly; Unit 304 is searched in range finding, is used for when each ONT/ONU reaches the standard grade, measuring its actual range, and according to the record of searching in the table corresponding to ONT/ONU that is identified at of ONT/ONU; Comparing unit 306 is used for the actual range that will measure and compares with the current distance that table is different from other records of record of ONT/ONU respectively; And authentication ' unit 308, being used for according to comparative result, whether ONT/ONU is legal in authentication.
In this system 300, authentication ' unit 308 when to be actual range identical with the current distance of arbitrary record in other records, judges that ONT/ONU is illegal at the comparative result of comparing unit 306, determines authentification failure; And be the current distance of the arbitrary record in actual range and other records when all inequality at the comparative result of comparing unit 306, judge that the distance of ONT/ONU is legal.
In sum, if according to publication number be the method disclosed in CN1855813 number the application for a patent for invention, the distance that employing ONT/ONU measures compares with the last time distance of oneself, and then this method does not support the normal of ONT/ONU to move, and promptly similar present phone is not supported the reel number telephone-moving.And adopt this method can support the normal of ONT/ONU to move, promptly support " the reel number telephone-moving among the GPON ".If certain ONT/ONU needs normal moving really, need be connected under the other branch optical fiber, the distance of measuring the first time after then moving was very big apart from difference last time sure and this ONT/ONU, if adopt distance that ONT/ONU measures and own last time apart from the method that compares, then will think illegal distance certainly, think that ONT/ONU is illegal ONT/ONU, will cause erroneous judgement like this.Adopt this method and system can overcome the problems referred to above, do not have erroneous judgement, because the distance of this branch optical fiber and other branch optical fibers is unequal.Therefore, adopt the present invention, can authenticate ONT/ONU in real time effectively, be notified to webmaster, can further handle, confirm whether exist the user to damage benefits of operators etc. mala fide.
Be the preferred embodiments of the present invention only below, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
