Description

A kind of xDSL terminal unit management system

Technical field

The present invention relates to the communications field, relate in particular to xDSL terminal unit management system in the broadband access field.

Technical background

Along with the development of communication network, there has been increasing user enjoying the facility that work, life and amusement brought that them are given in the broadband.In numerous broadband access technologys, the xDSL technology utilizes existing twisted-pair feeder resource as transmission medium, adapt to different customer demands, development has formed asymmetric digital subscriber loop (ADSL), single line to high-speed digital subscriber line (SHDSL), very high bit rate digital subscriber loop multiple access technologies such as (VDSL), obtained in the world to use widely, obtained good economic benefit and social benefit.

With the ADSL access technology is example, and its network application model as shown in Figure 1.At local side (CO end), Digital Subscriber Loop inserts multiplexer (DSLAM) equipment the twisted-pair feeder interface is provided, and places terminal equipment ADSL Transceiver Unit-Remote end (ATU_R) at user side, and both cooperate realization broadband access function.ATU_R provides telephone terminal interface and data terminal interface for the user simultaneously, hold at CO, DSLAM equipment is by business network interface (SNI) accessing to wide band network, and the analogue voice signal of substation is then by frequency band isolation technics accessing public switched telephone network (PSTN) network.Because the difference of modulation technique, frequency band division etc., different xDSL connecting systems is slightly different with the ADSL system in network application, for example when VDSL inserts between the VTU_R of the DSLAM of CO side and user side transmission range nearer, and SHDSL is owing to adopt baseband transmission, can not share circuit with the arrowband simulated voice, but the broadband access application mode is similar substantially.

Network management system (nms) manages maintenance to the DSLAM equipment in the network.The xDSL terminal equipment of user side is realized specific function as a link of broadband access solution, needs the network operator that their operating state is managed maintenance equally.XDSL terminal equipment One's name is legion, widely distributed for reaching effective operation broadband network, reduces network operator's management maintenance cost, better for the broadband user provides service, need provide perfect solution for the management maintenance of xDSL terminal equipment.

The management maintenance mode of present topmost xDSL connecting system as shown in Figure 2.In network model shown in Figure 2, the DSLAM equipment of CO end manages maintenance by network management system NMS, and network management system is built according to the network planning is unified by the network operator, and each DSLAM equipment in the network is carried out centralized and unified management.General operation snmp management agreement between NMS and the DSLAM system.

The position of xDSL terminal equipment is at user side, generally can only realize the collection of the general physical circuit parameter information of XTU_R side and report at CO end, and can not realize management maintenance function to xDSL terminal whole system, uni interface, the management maintenance of this respect need carry out at subscriber's local, the xDSL terminal equipment provides this management maintenance interface for the user, for example, realize management by character agreements such as xModem by the RS232 asynchronous serial port; Or, realize management maintenance etc. by modes such as HTTP, Telnet by the 10Base-T Ethernet interface.

But there is following shortcoming in such scheme:

(1) centralized management that can not realize the xDSL terminal equipment is safeguarded.In such scheme, network management system can only realize the management maintenance of local side DSLAM equipment, carries out at user side for the managerial demand of terminal, can't realize effectively administering and maintaining broadband network.

(2) network operation maintenance cost height.The management maintenance of xDSL terminal equipment can only carry out at user side, when maybe needing upgrading, end product generation problem must safeguard to the doorstep when dealing with problems like this, such problem comprises the fault of terminal equipment itself or the user misoperation to terminal equipment, and maintenance cost is very high.

(3) be unfavorable for network equipment compatibility.Must there be default configuration in the xDSL end product when the payment user uses, for example the ADSL terminal must dispose asynchronous translative mode permanent virtual connection (ATMPVC) when offering the user, and connection identifier VCI/VPI (VPI/VCI) of PVC must be identical with the configuration of the last corresponding port of DSLAM.And the DSLAM product produced of different manufacturers in fact, the VPI/VCI of its port PVC default configuration is also inequality, and this could adapt to different DSLAM equipment requirements with regard to requiring the configuration parameter of terminal made amendment.

(4) can not realize terminal exempt from the configuration.Terminal equipment is when dispatching from the factory, perhaps when providing to the user, must connect by the professional needed ATM PVC of configured in advance, if the configuration of dispatching from the factory of equipment can not be fit to service needed, must change one by one, need a large amount of attendant of operator when causing the broadband user to open an account, this extensive operation to the broadband is very unfavorable.The misoperation that the user carries out terminal equipment also will directly influence the user and use.

Can't realize the problem of xDSL terminal unified management in order to solve such scheme, produce terminal management technology shown in Figure 3.In numerous xDSL access technologies, current application is the ADSL access technology the most widely, is to be born and to grow up in the basis with the atm technology.Between ADSL Transceiver Unit-Central Office end (ATU_C) and ADSL Transceiver Unit-Remote end (ATU_R), pass through ATM PVC carrying user data, professional PVC as shown in Figure 3.Therefore, be easy to expect realize ADSL Termination Unit management, the basis of this technical scheme that Here it is by setting up a PVC again.Equally, the SHDSL that such way to manage also is suitable for the ATM mode inserts.

As shown in Figure 3, on DSLAM or its atm device, adopt the translation-protocol termination management PVC of ATM/IP such as 1483B or IPoA, operation is based on the terminal supervisory entity of transmission control protocol/Internet protocol (TCP/IP) protocol stack, it is communicated by letter with terminal equipment by management PVC, constitute the passage of management information, under the control of terminal management system, realize every management function of terminal equipment, as data configuration, software upgrading, statistics maintenance, diagnostic test etc., these management functions all are based upon on the ICP/IP protocol stack fully.Terminal equipment needs to realize at least that two ATM PVC of configuration connect, article one, be used to carry the user's data business, another is used for bearer management information, simultaneously, also must move a management entity, the management entity protocol communication by appointment on realization and DSLAM or other equipment is to realize management function.Generally speaking, the communication protocol of agreement is based on TCP/IP, and management entity need dispose the identification that corresponding IP address is used for management entity.

Compare with technology one, the improvement of technology two maximums is can realize the centralized and unified management of terminal, and the network operator needn't hurry back and forth between the user of each dispersion for maintenance terminal equipment again.But still there are some significant disadvantages in this technology.

(1) compatibility issue is more serious.Compare with technology one, need the xDSL terminal equipment to hold on the DSLAM device port in the technical program and all exist 2 ATM PVC to be connected with CO.Terminal equipment dispatches from the factory or pays the user when using, and these two PVC must be configured and finish and in full accord with the configuration parameter of CO end DSLAM equipment corresponding port.Corresponding different operators, the configuration of its management PVC and professional PVC may be fully different, therefore will guarantee that the configuration consistency of PVC is difficult to accomplish.

(2) cause the complicated and cost rising of equipment.Set up management PVC and connect the interface channel of just having realized between DSLAM and the XTU_C, realize the management maintenance function, also need to be structured in the upper-layer protocol on the PVC passage.The most feasible mode is by TCP/IP, and this just requires the management entity of terminal equipment to support TCP/IP.Its protocol stack as shown in Figure 4.

Like this, on the management entity of terminal equipment, must realize complicated IP stack, be necessary for terminal supervisory entity distributing IP address.According to the practice situation, terminal equipment generally adopts the transparent bridging mode, and inside does not need the IP address.Like this, support the terminal equipment complexity of management to improve, and need to consider the planning and the assignment problem of IP address of terminal that cause management difficulty to strengthen, correspondingly cost also rises.

At local side,, need relevant hardware equipment to realize for the management PVC of each terminal that terminates.When management PVC that needs terminate all simultaneously, being equivalent to each terminal has increased an online user, needs to increase very big equipment cost.

(3) can't realize a plurality of terminal equipments are managed simultaneously.The front is mentioned, when adopting the technical program, terminal supervisory entity need be distributed an IP address, how to dispose this IP address? for guarantee this address be the DSLAM side management entity as can be known, feasible way is the default IP address of unified configuration when terminal is produced, this problem of bringing is exactly, the management ip address of all xDSL terminal equipments all is identical, thereby, when needing access terminal equipment that they are managed, the network operator can only adopt the mode of carrying out one by one, has only the terminal that disconnects current connection could visit another terminal, and can not manage a plurality of terminal equipments simultaneously, this is very inconvenient.

(4) can't realize the VDSL terminal unit management.Be suitable for xDSL access technology based on the connection management passage of PVC based on ATM, as ADSL and SHDSL, when the ATM connection has not existed, for example for VDSL access technology based on Ethernet, this Managed Solution will be no longer suitable, must make up other management channels, the Managed Solution of various xDSL technology can't be unified.Thereby need on the DSLAM equipment of CO end to be the different different management entities of xDSL access way operation that this has also increased the complexity of CO end equipment.

(5) still can not realize terminal exempt from the configuration.See that from technical scheme terminal equipment still must be configured before use, comprise service channel and management channels, and corresponding IP protocol configuration, the difficulty of the operation of opening an account is strengthened.

Summary of the invention

When the objective of the invention is to be implemented in the xDSL line activation, do not have under any configuring condition in terminal, by centralized configuration, test and the monitoring of CO end realization to terminal, reach the purpose that terminal is powered on and disposes automatically and exempt to safeguard automatically to the doorstep, under the local side management system cooperates, realize the plug and play (plug andplay) of terminal.

For this reason, the present invention adopts following scheme:

Embodiment

Below in conjunction with Figure of description the specific embodiment of the present invention is described.

The present invention proposes to have solved following problem:

(1) makes up a perfect xDSL terminal unit management system, clear definition management information platform, DSLAM equipment, the required function that possesses of xDSL terminal;

(2) realize the real zero configuration of xDSL terminal equipment, do not need to do special configurations, solve terminal and DSLAM data compatibility problem for terminal management;

(3) realization is to the unification of various xDSL terminal management technology;

(4) definition administrative skill protocol stack is simplified DSLAM, terminal function, reduces the requirement to equipment greatly, realizes Managed Solution cheaply;

(5) solve the problem of managing a plurality of terminal equipments simultaneously.

As shown in Figure 5, be in the embodiment of the invention, xDSL terminal unit management reference model.Its terminal management system scheme is made up of terminal unit management unit, CO end DSLAM system and xDSL terminal equipment.This local side DSLAM equipment and user side xDSL terminal equipment have management entity respectively, and terminal unit management unit and each management entity have management information bank (MIB) respectively, realize every management function;

This system schema comprises following several interface:

(1) management interface between terminal unit management unit and the CO end DSLAM system.Between the management entity of this interface in terminal unit management unit and DSLAM equipment, can be by the indirect control of its realization to terminal equipment.

(2) interface between xDSL terminal equipment and the CO end DSLAM.Between the management entity and xDSL terminal unit management entity of this interface in DSLAM equipment, realize the transmission of terminal unit management information.

(3) interface between file server and the xDSL terminal equipment.This interface is finished transmission into file by this interface between the document upgrading entity of file server and xDSL terminal equipment, cooperate operations such as the file download of finishing ustomer premises access equipment, software upgrading with the terminal unit management system.

In terminal management system scheme shown in Figure 5, user interface and network components association process are realized in the terminal unit management unit, the DSLAM system realizes the conversion and the transparent transmission of administrative message between terminal unit management unit and the terminal equipment, and terminal then realizes management agreement and access control.The terminal unit management unit is by the dereference of DSLAM realization to terminal, final centralized management and the maintenance that realizes all terminals.Wherein the DSLAM system carries out the conversion of transparent processing and basic communication protocol to terminal management information, realize communication interface respectively with terminal unit management unit and terminal equipment, do not do the management agreement analyzing and processing, like this, after the expansion of terminal management information or upgrading, only need carry out the corresponding modification upgrading and just can support new management function, and needn't change DSLAM system itself, with the interface that adapts to terminal equipment and the needs of the continuous development and change of function the terminal unit management unit.

The terminal unit management unit can be used as independently, and management system exists, also can be integrated among the network management system NMS of DSLAM equipment, adopt the management of snmp protocol realization to the xDSL terminal equipment, this equipment operation management mode with general networking is consistent.Management entity mentioned in this article, it is the functional module that runs on the equipment, simply say, operate in SNMP Proxy module and the SNMP Agent module that operates on the terminal on the DSLAM equipment exactly, their effect is that the snmp message that " terminal unit management unit " issues is delivered on the terminal equipment, and the execution information concerning order, do corresponding management maintenance operation.And the effect of network management system (nms) itself is to be used for managing the DSLAM network, in other words conj.or perhaps manages DSLAM equipment, and his form generally is a high performance work station.Between it and the DSLAM equipment is by snmp protocol, therefore, adopt method of the present invention after because " terminal unit management unit " also is to come the office terminal by snmp protocol, so this " unit " just can be integrated in the NMS internal system of DSLAM equipment.

Below just realize that by snmp protocol the management to terminal equipment is an example with network management system, illustrate in the ADSL connecting system, how to realize the management of ADSL Termination Unit, by other upper-layer protocols or for other xDSL interfaces, its technical scheme is similar.

As shown in Figure 6, be the protocol model of realizing the ADSL system management in the embodiment of the invention by SNMP.When terminal management was carried out based on the SNMP mode, the SNMP message was carried on the EOC passage of ADSL, and the link layer control protocol adopts HDLC.Like this, as long as the xDSL line synchronization, just can realize that the management information between CO end and the terminal is mutual, release reaches the purpose of exempting from configuring maintenance to the requirement of the default configuration data of terminal and IP address, agreement.

When the terminal unit management unit needs the information of office terminal, the SNMP message will send to DSLAM equipment, DSLAM is checked through the administrative message that this message is a terminal, the method of SNMP proxy will be adopted, HDLC passage by the xDSL circuit, the SNMP message is transmitted to terminal, and terminal receives the SNMP message on the HDLC of xDSL link, and makes corresponding processing according to the SNMP message.When the SNMP of terminal reports the terminal unit management unit, then adopt opposite flow process.Because SNMP as application layer, directly is based upon on the HDLC, therefore there is not the ICP/IP protocol layer, do not need configurations such as IP address.

Terminal management also can be carried out based on other upper-layer protocols (for example IP agreement), perhaps uses for other xDSL, also can realize managing and use by embedded passage (EOC) carrying of other xDSL.Its Protocol REference Model as shown in Figure 7.This moment, the DSLAM system realized corresponding protocol adaptive (for example IP agreement), by embedded passage (EOC) carrying of xDSL.As shown in Figure 7.But in this manner, require to have the IP default configuration in the xDSL terminal equipment, this default configuration must meet the agreement with network management system.

Among the MIB in network management system, the MIB of xDSL terminal is the part as the management information bank of DSLAM system (MIB), sets up the index to terminal MIB under the xDSL of DSLAM port MIB.Carrying out business configuration, when for example carrying out the configuration of ADSL terminal PVC, network management system realizes the integrated configuration of PVC, after determining the PVC configuration of CO end, automatically realize the PVC configuration of terminal under the coordination of network management system, like this, the PVC of ADSL terminal no longer needs independent configuration.The process of issuing of other configuration datas is similar.All configuration informations of terminal all need be preserved in network management system, and can be handed down to terminal in needs.Network management system needs transmitting order to lower levels after the configuration of finishing terminal, require terminal configuration data to be kept among the nonvolatile memory of inside, the configuration data during as terminal equipment startup next time.

CO end DSLAM system realizes SNMP Proxy, and itself does not analyze the content of terminal management information, does not preserve the configuration information of terminal yet, but realizes the transparent transmission forwarding of management information between network management system and the terminal.When receiving network management system to the visit of the terminal MIB under the xDSL port, the DSLAM system realizes the forwarding of snmp message as Proxy, after receiving snmp message, the SNMP message is carried in the HDLC frame, is transmitted to the xDSL terminal by the EOC passage.

The interface definition of HDLC and EOC is with reference to the ITU-TG.997.1 standard, and the xDSL nest plate of main flow is all supported this interface, is realized the encapsulation process of preparation, acceptance/transmission and the HDLC frame of HDLC frame data message by the nest plate driver.As shown in Figure 8, be the interface of SNMP message and HDLC.

When not adopting other top management (as TCP/IP) agreement, also can carry out according to similar adaptive mode by SNMP.

Terminal operating SNMP Agent realizes every management function that terminal management MIB defines.Communicate by letter with terminal unit management unit (network management system) and to realize every management function.Under the order control of network management system, all configuration informations are preserved on terminal, write non-volatile memory, and when start next time, enable the configuration data of preservation.

The beneficial effect that technical solution of the present invention is brought:

(1) realization xDSL terminal is exempted from configuration.As long as the xDSL line synchronization just can realize terminal management, do not need terminal equipment is carried out any default configuration, comprise PVC, protocol configuration etc.Terminal transparency, adaptability are strong;

(2) realize the centralized management of xDSL terminal.Can remove to the work of terminal local maintenance at the management maintenance of unified administrative center's realization, greatly reduce the network operation maintenance cost the whole network xDSL terminal equipment;

(3) realize the whole network xDSL terminal equipment while management maintenance.For basic maintenance management function, do not need the built-in IP of terminal address, the address resource that has brought when having avoided IP address assignment and default configuration is wasted, and can't visit the problem of a plurality of terminal equipments simultaneously.

(4) management function is easily expanded.DSLAM equipment is realized the Proxy function, carrying out transparent transmission for concrete top management message transmits, like this, development along with technology, when terminal equipment provides new user interface or new business function, only need make amendment to upgrade and promptly can support, needing avoid upgrading the whole network DSLAM equipment unified network management system.

(5) terminal management scheme cheaply.Management channels supported by xDSL chip itself fully, and local side apparatus does not need to be the extra hardware device of the terminal management configuration management channels that terminates that cost will reduce greatly.

The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
