Abstract
The method includes following steps: (1) customer premises equipment (CPE) informs automatic configuration server (ACS) that parameter attribute is lost; (2) ACS reinstalls parameter attribute of the CPE. Overcoming disadvantages of current technique, the invention deals with loss of parameter attribute (restarting device without saving parameter attribute or restoring value set by factory for device) reasonably as above. Thus, ACS does not need to reset parameter attribute for CPE blindly whenever discovering CPE is restarted each time.
Description
Technical field
The present invention relates to DSL (DSL Digital Subscriber Loop Digital Subscriber Line) technology, specifically, relate to CPE among the DSL (Customer Premises Equipment customer premises equipment, CPE) technical field.
Background technology
Insert the broadband access technology of family at present based on DSL, what prior art mainly adopted the proposition of DSL forum is the technical scheme of the technical report family recommendation of core with TR069 (Technical Report technical report), this scheme disposes CPE automatically by ACS (Auto-Configuration Server Automatic Configuration Server), and by ACS CPE is suitably managed.
TR069 adopts based on HTTP (Hypertext Transfer Protocol, the agreement that the WWW service routine is used) soap protocol (Simple Object Access Protocol is based on the Simple Object Access Protocol of XML grammer) is used for the visit of ACS to CPE, and the function of calling by ACS that defines that a lot of CPE realize, be referred to as method (Method).ACS sends the process that a message of calling certain method finishes appointed function by CPE then to CPE and feed back execution result and is called far call, is called for short RPC.Therefore CPE offers the method that ACS calls and is called the RPC method again.
TR069 has defined the CPE data model, and the CPE parameter hierarchically is organized into tree structure, and the leaf of tree is concrete parameter (Parameter), and the above node of leaf is called object (Object), so object also is the set of one group of parameter or object.Parameter have whether can rewrite, readable build-in attribute whether, whether also have in addition when value changes to ACS to send notice (Notification) and who can visit the attribute of this parameter (AccessList).
The value of the Notification attribute of parameter can be 0,1,2, is illustrated respectively in and does not send notice when the value of parameter changes under the specified conditions, waits for sending when the next cycle session is set up and notify and set up immediately session transmission notice (being described below about session).TR069 has defined the initial Notification attribute value of parameter, but ACS can call this property value that the method SetParameterAttributes that parameter attribute is set of CPE revises one or more parameters.
The AccessList attribute initial value of parameter is empty, and meaning promptly can only be visited by ACS, and ACS can call the SetParameterAttributes method other visitor is set, for example the user of LAN (local area network (LAN)) side (ACS is in the WAN of CPE (metropolitan area network) side).
The method GetParameterAttributes that gets parameter attribute that ACS can call CPE inquires about the attribute of one or more parameters of specifying CPE.
Session in the prior art between ACS and the CPE is based on http protocol, therefore any mutual requirement between ACS and the CPE connects (ACS also can ask CPE to initiate to connect, but ACS can't be to the CPE request of sending in some cases) by the HTTP that CPE is initiated to ACS.ACS provides the Inform method to call to create a connection for CPE.In this Inform message, carry CPE device flag information (Deviceld), cause creating the incident (Event of this connection, among Inform of TR069V1 definition 16 Event can be arranged at most), produce parameter (ParameterList comprises parameter name and value) and the message negotiation parameter and the CPE current time information etc. of incident.
Wherein incident (Event) is the event type of describing with a character string, and as the event type code, space of heel is the description of the type incident to this character string then with a leading character.Need ask configuration file when for example device first is established to the connection of ACS, its incident is " 0BOOTSTRAP "; Power on and resetting at of any reason that equipment disposition is later excessively start the back and send the incident of value for " 1BOOT ".Except numeral, leading character also can be a letter, and the leading character that CPE carries out the incident that sends after certain method is " M ", and the incident that sends before equipment really resets when for example carrying out Reboot (promptly restarting) order is " M Reboot ".The self-defining incident of producer with " X " as leading character, for example " X 00D09E MyEvent ".
The incident leading character that TR069V1 has defined has ' 0 ', ' 1 ' ..., ' 8 ', ' M ', ' X '.
The change of parameter value also is a kind of incident, and event type is " 4VALUE CHANGE ".TR069 regulation if the change of the value of certain parameter is not that for example the leading subscriber operation of LAN side is that produce and Notification attribute this parameter is non-0 from other external factor because ACS initiatively is provided with, then should be reported this incident to ACS.If the value of Notification is 1, wait until then to create when the next cycle session cycle arrives to connect this incident of transmission that this is a kind of Passive Mode.If the value of Notification is 2, then initiatively creates connection immediately and send this incident.
TR069 has defined the method SetParameterAttributes that parameter attribute is set that CPE should realize, ACS calls Notification and the AccessList attribute that the method is revised the parameter of CPE, and ACS can call the current attribute of the GetParameterAttributes method query argument of CPE.
In the prior art after ACS has revised the CPE parameter attribute CPE may not preserve new property value, therefore if the CPE property value of not preserving new property value or preservation is lost (for example equipment to restore delivery setting), CPE can not regain parameter attribute, and the parameter value that ACS may therefore can not obtain to be paid close attention to changes incident and to the control of parameter access authority.Though whether ACS can periodically call the parameter attribute of GetParameterAttributes inquiry CPE correct, can not in time obtain notice under the situation that parameter attribute is lost, and relies on periodic queries to increase load and the offered load of ACS undoubtedly.
Summary of the invention
The method that the object of the present invention is to provide a kind of CPE parameter attribute to handle, with solve that CPE does not preserve parameter attribute or the parameter attribute of being preserved lose after how with the ACS problem to obtain again alternately.
For achieving the above object, technical scheme provided by the invention is as follows: the method that a kind of customer premises equipment, CPE CPE parameter attribute is handled, described method comprises the steps:
A, when CPE has lost the parameter attribute that Automatic Configuration Server ACS is provided with, CPE sends parameter attribute to ACS and loses incident, notice ACS parameter attribute is lost;
B, ACS reset the parameter attribute of described CPE.
Wherein the described CPE notice of step a Automatic Configuration Server ACS parameter attribute is lost by " parameter attribute is lost incident " and is realized.
Wherein said " parameter attribute is lost incident " " 9ATTRIBUTES LOST " for carrying in the Inform message.
Wherein step a specifically comprises:
If CPE does not preserve parameter attribute, then CPE notifies Automatic Configuration Server ACS parameter attribute to lose when restarting at every turn, and perhaps CPE detects parameter attribute and loses in normal course of operation, then notifies the ACS parameter attribute to lose.
Wherein step b specifically comprises:
B1, ACS receive that described CPE parameter attribute loses the parameter attribute setting operation record that the CPE that is preserved is checked in notice back;
B2, ACS are provided with parameter attribute to described CPE again according to the parameter attribute setting operation record of described CPE.
Wherein step b specifically comprises:
B1, ACS are configured the back by automatic configuration mechanism to described CPE and check whether preserve described CPE parameter attribute setting operation record;
If b2 has described CPE parameter attribute setting operation record, ACS resets its parameter attribute.
The present invention overcomes the deficiencies in the prior art, by device losses at any time lose by CPE notice ACS parameter attribute during the CPE parameter attribute that is provided with of ACS (do not preserve parameter attribute is just restarted or artificially with the equipment to restore delivery value) and realize reasonable processing the CPE parameter attribute by the technical scheme of ACS Reparametrization attribute, thereby make ACS needn't find all to reset blindly when CPE is restarted CPE parameter attribute or CPE at every turn and can not preserve parameter attribute to save the space reduction equipment cost of permanent memory, simultaneously whether ACS no longer to need periodically to inquire about the parameter attribute setting of CPE correct, effectively alleviated offered load and ACS load.
Description of drawings
Fig. 1 is for ACS of the present invention and preserve the mutual flow chart of CPE of parameter attribute;
Fig. 2 is for ACS of the present invention and do not preserve the mutual flow chart of CPE of parameter attribute;
When Fig. 3 sends BOOTSTRAP message for CPE of the present invention and the mutual flow chart of ACS.
Embodiment
The present invention is described in detail below in conjunction with specific embodiments and the drawings.
The present invention adopts following technical scheme basic ideas as follows: increase a parameter attribute and lose incident on the basis of the existing incident of the definition of TR069, CPE sends the message carry this incident to ACS where necessary, and ACS obtains the parameter attribute of resetting CPE after this message as the case may be.
1, parameter attribute of definition is lost incident;
At first, on the basis of existing incident, increase a new incident leading character and lose incident for the parameter attribute of ' 9 ' (or other special character), complete description can be " 9ATTRIBUTES LOST " or other similar description, is used for representing the situation that parameter is lost.
2, CPE loses incident to ACS transmission parameter attribute;
CPE is when starting, if CPE is saved in permanent memory with the parameter attribute that ACS is provided with, take out these property values from memory and needn't require ACS to reset in start-up course, CPE only needs to send the BOOT incident after startup in such cases.But needn't limit CPE transmission parameter attribute and lose incident.
CPE is when starting, if CPE does not preserve the parameter attribute that ACS is provided with, then increase parameter attribute after the BOOT incident that when starting, sends and lose incident (" 9 ATTRIBUTES LOST "), partly add the BOOT incident simultaneously and parameter attribute is lost incident at the Event of message structure when promptly CPE calls the Inform method and is created to the connection of ACS.
CPE is after startup, and no matter whether CPE preserves parameter attribute, just can send parameter attribute to ACS and loses incident if CPE has lost parameter attribute.
3, the parameter attribute of ACS response CPE is lost incident;
ACS preserves the attribute setting operation to CPE in the technical solutions according to the invention, if ACS receives that at any time the parameter attribute of CPE has the operation note of this CPE parameter attribute setting just can to this CPE parameter attribute be set again when losing incident like this.
ACS receives and loses after the incident (use Inform method) parameter attribute of CPE at first the dialogue mechanism according to TR069 gives a response to this incident, ACS will call the Inform of CPE to response message of CPE feedback, if CPE receives response message, mean that then ACS receives this message really.ACS needn't inform in parameter attribute is lost the response message of incident that CPE whether can the Reparametrization attribute, so this response message printenv.
Check the parameter attribute setting operation record whether this CPE is arranged really after the ACS,, just call the SetParameterAttributes method of CPE, the parameter attribute of being preserved is provided with once more to CPE if having.If the parameter attribute setting operation record of this CPE then need not send any message to CPE.
Describe below in conjunction with flow chart:
The mutual concrete flow chart of CPE and ACS was as shown in Figure 1 when CPE preserved parameter attribute:
Step 101, CPE start.
Step 102, CPE start the back and send a BOOT incident to ACS, do not have parameter attribute to lose incident.
Step 103, ACS are at response message of BOOT incident loopback.
Step 104, ACS and CPE carry out that some is mutual.
Step 105, ACS initiatively are provided with parameter attribute to CPE, generally are that manual operations or ACS realize automatically according to certain script.
Step 106, CPE preserve parameter attribute to permanent memory.
Step 107, CPE finish the attribute setting and preserve back response ACS.
Step 108, ACS receive and know after the response success this time is set, and the parameter attribute setting operation that is carried out is preserved, and how to preserve by ACS to determine.(if be provided with fail then ACS should not preserve operation this time)
Step 109, restart at CPE sometime.
Step 110, with step 102.
Step 111, with step 103.
Do not lose incident because CPE sends out parameter attribute, therefore do not have ACS to reset the subsequent step of parameter attribute to CPE.
The mutual concrete flow chart of ACS and CPE was not as shown in Figure 2 when CPE preserved parameter attribute:
Step 201, CPE start.
When ACS sends the BOOT incident, in message, increase parameter attribute simultaneously after step 202, CPE start and lose incident, i.e. " 9 ATTIBUTES LOST ".
Step 203, ACS lose response message of incident loopback at BOOT and parameter attribute.
Step 204, ACS and CPE carry out that some is mutual.Because ACS did not make the parameter attribute setting operation to CPE before, ACS does not have the operation from trend CPE Reparametrization attribute now.
Step 205, ACS initiatively are provided with parameter attribute to CPE, generally are that manual operations or ACS realize automatically according to certain script.
Step 206, CPE finish attribute response ACS in back are set.
Step 207, ACS receive and know after the response success this time is set, the parameter attribute setting operation that is carried out is preserved.If (be provided with and fail then ACS should not preserve operation this time.)
Step 208, restart at CPE sometime, because CPE does not preserve parameter attribute, so the parameter attribute that ACS is provided with is lost.
Step 209, with step 202.
Step 210, with step 203.
Step 211, ACS find this CPE was carried out the parameter attribute setting operation, to this CPE parameter attribute are set again automatically.Subsequent process and step 5,6,7 similar, just ACS needn't repeat to preserve the parameter attribute setting operation.
In addition, processing when ACS receives the BOOTSTRAP incident of CPE is different from that above-mentioned CPE restarts or CPE parameter attribute in normal course of operation is lost the handling process of incident, CPE sent to and did not need to carry parameter attribute in the message of ACS and lose incident this moment, specified as follows:
CPE does not pass through configuration or has recovered Default Value by send this equipment of BOOTSTRAP representations of events to ACS, this moment, ACS can dispose this CPE (notice CPE download configuration file by automatic configuration mechanism, the value that comprises parameter in the configuration file, but do not comprise the Notification and the AccessList attribute of parameter).This moment, ACS should check whether once this CPE was provided with parameter attribute, if having then should reset the parameter attribute of this CPE after finishing automatic configuration.Idiographic flow is as shown in Figure 3:
Step 301, CPE start.
Step 302, because CPE did not also dispose, send the BOOTSTRAP incident to ACS.
Step 303, a message response BOOTSTRAP of ACS loopback incident.
Step 304, because CPE has sent the BOOTSTRAP incident, so ACS initiates automatic layoutprocedure (process detailed step slightly).
Step 305, finish automatic configuration after, ACS judges whether that the parameter attribute of this CPE is provided with record.
If there is the parameter attribute of this CPE that record is set on step 306 ACS, then ACS resets parameter attribute from this CPE of trend.
On step 307, the ACS not the parameter attribute of this CPE record is set, skip the step of reseting parameter attribute, enter normal reciprocal process.
