Abstract

A plurality of elements of a system, such as a telecommunications network are controlled by generating a generic instruction, in a generator, selecting the element for which the instruction is directed, in a matcher and interface module and transmitting the instruction to the respective elements. By transmitting a generic instruction applicable to all relevant elements, the operator of the system can control all the elements with a single instruction. A generic instruction can be translated in translators into separate instructions applicable to each individual element or defined groups of elements.

Description

The control assembly of communication network

The present invention relates to the control assembly of communication network, particularly but not exclusively be used for traffic administration.

Though modern communication network is supermatic, they still require some supervision and centralized control, so that handle the recurrent situation such as overload condition.A kind of typical example is that a given telephone number is sent increasing suddenly suddenly of a plurality of callings, perhaps be because the result of the telephone number that in the advertisement of television broadcasting, is providing, situation about during crying into, being shown, or under the situation of the emergent contact telephone number that on press Communique, provides when important accident of report or natural calamity.

This result who increases is suddenly transshipped not only comprises direct circuit, but also the Local Exchange of promising its service (being also referred to as switch).Owing to attempt to call out a telephone number all trunk lines of serving this switch are all hurried, cause all being in obstructed state, thereby make this switch in paralyzed state from exhalation and incoming call by each user of this switch service.

The destination volume controlled notion of having developed such as call congestion and duration of a call overcomes this problem.Call congestion is by the exchange arrangement of starting a certain proportion of calling of a destination number to be excluded.Duration of a call is arranged to, to the calling of an order label make repay examination after, until predetermined time interval in the past after, no longer this number is made and further repays examination.These two kinds of calling systems reduce because the unnecessary use of examination to junction network repaid in the calling of losing efficacy.

Communication network being carried out problem that centralized control occurs is inequality the causing of each switch in common network.This is because in developing network, in any given time, and will be at the switch that uses more than a type.Have again, can cause the dissimilar of the switch that is fit to diverse location by each regional different characteristics of different switch services.Therefore, some function may only can be used in some switch, even perhaps under this function is general situation, may require different instructions to go to operate them.Some service in addition may require only to be used for the substation through selecting of each switch such as duration of a call and call congestion, is broadcasted at service area such as some telephone numbers like that.

As everyone knows, for example from number of patent application WO93/18598 (Nokia), can learn that produce an order for network components with puppy parc, this order is translated into the agreement that is fit to for the network components that is connected.Yet system user hereto sends order to will controlled each parts being necessary with puppy parc.It can be time-consuming and problematic doing like this, for example, if require in several switch collaborative works and they some not have necessary function.

According to first aspect of the present invention, a kind of method of controlling a plurality of parts of communication network is provided, comprise producing universal command, sending to alternative pack and sending instructions to the step of each parts accordingly for instruction.

According to second aspect of the present invention, a kind of controller that is used to have the communication network of a plurality of functional parts is provided, comprise the device that produces universal command and be used to send instructions to the device of corresponding each parts, it is characterized in that having the device of selecting each parts that this instruction sent to.

Utilize the transmission universal command can be delivered to all associated components, the operator of system can utilize a kind of all parts of single commands for controlling.A universal command can be translated into other each instruction of branch of the parts group that can be delivered to each independent parts or regulation.

Some parts may not have the ability of some function, and this method can provide, if the parts of one or more selections can not be carried out desired instruction, does not then send instructions to these parts or this some parts.Yet the ability that network is carried out desired function as a whole may depend on that each parts carries out the ability of predetermined function.Therefore this method can provide, if any parts can not be carried out desired instruction, does not then send instructions to any parts.In other words, unless require all parts of cooperation can carry out their instruction separately, otherwise do not send instructions to any parts.Under another situation, some network function is independent of other parts by the some parts of this network to be operated and can carry out, this method can provide so, if any parts can not be carried out this instruction, then this instruction only is sent to those each parts that can carry out this instruction.

Different compatibility rules may be applied to different network functions.

In a kind of preferred arrangement, instruction can be produced and store, so that send in response to predetermined condition.This makes network automatically and quickly respond to certain condition, such as the part overload that takes place in the system of being positioned at.

Predetermined condition can be preset time expiration at interval, allows to carry out in advance the layout of network control.For incident clocklike, such as the plan of " crying into " weekly or every day, this time interval can be repeated to be provided with after each instruction sends.But for the situation such as the isolated appearance of special event, then the time interval no longer repeats to be provided with.

Each instruction to network components can be arranged to forbidding of a signaling capability of generation.For example, if calling system overload to an independent number, and this number must be handled (for example the free dialing numbers of conversion is the switch number) through number translation, then by being sent to the call set-up signal of forbidding of number translation parts, the calling of this number can be spaced apart or block.This prevents the signaling network attempting blocking, but call setup is failed midway, and makes the traffic network itself alleviate load.

In a preferred embodiment, this method comprise with high-level language produce instruction, preference pattern output, interface type message, conversion high level instructions for with each corresponding component type instruction of the form of compatibility and the mode data and the canned data of relatively selection mutually, to select the step of the parts that this instruction will be sent out.

Each embodiment of the present invention is described with reference to the mode of each accompanying drawing with example, wherein:

Fig. 1 a represents to be illustrated according to a kind of arrangement of the present invention by a kind of simple communication network of network manager control;

Fig. 1 b is a kind of communication network with other signaling network of branch, arranges according to another kind of the present invention with explanation;

Fig. 2 represents to implement the correlation of each functional part of network manager of the present invention and they and some switching centers;

The simplification of the memory unit 17 of Fig. 3 and 4 presentation graphs 2 details;

Fig. 5 represents the explanation according to the planning chart of the single of the present invention's operation;

Fig. 6 represents the explanation according to the planning chart repeatedly of the present invention's operation;

It is how to realize such plan control that Fig. 7 represents according to the present invention.

Fig. 1 a represents to have the simple communication network of 6 switches (exchange) A1, A2, B1, B2, B3, C1, and these switches are all operated under the control of network manager M.Respective switch interconnects by each traffic carrier link (1,2,3,4,5,6,7,8,9,10, solid line) and each switch is connected to network manager M by control corresponding link (40,41,42,43,44,45, dotted line).

The distortion of Fig. 1 b presentation graphs 1a.For simplicity, only as shown in Figure 1a pass through 3 switch As 1, B2, B3 that traffic network 4,9,10 is connected are expressed out and also are connected to the signaling parts T that comprises some translater TX by signaling network 31,32,33.Switch A 1, B2, B3 and signaling parts T pass through link 40,42,45,46 respectively under the control of network manager M.Each switch A 1, B2, B3 are connected to a plurality of user terminals (only expressing respectively under 21,22,23 every kind of situations).

The relation of implementing each functional part of network manager M of the present invention and they and network is indicated on Fig. 2.Network manager M comprises memory 17, and this memory stores is about the sign of each switch and the link between them.These signs are included in each exchange installed device type, for example can be A type, Type B and the C type and the geographical position of often using in system X, AXE10 and the 5ESS type of British Telecom, be labeled as X district (A1, B1, B2 are the center) in this example, Y district (A2, C1 are the center) and Z district (B3 is the center).These districts can be determined by any suitable standard or the combination of this standard.For example, when number is in one of broadcasting, the TV area of coverage can be suitable for being identified for each switch that is controlled of duration of a call purpose, and for such as utility companies such as transportation, power supply, running water, according to the area structure of this utility company, may require an inquiry circuit.Can determine a plurality of such geographical.Be stored in data in the memory 17 and can also comprise the data of the current state of each parts, the data that the input by each network components is updated.

The structure of network manager is known for the professional and technical personnel.Typical network manager be by one computer implemented, its software provides each necessary function parts.

Network manager M has three types input, promptly, come the time indication of self-clock 11, man-machine interface 12 and monitor 13, monitor receive from each input signal of network N and by man-machine interface 12 send message to operator or generation to network manager from dynamic response.Man-machine interface 12 links to each other with network traffic control program storehouse 20, the pattern of the input that this program library can storage standards.

The input signal that universal command generator 14 receives from man-machine interface 12 and monitor 13.Universal command generator 14 is by three outputs: an instruction that is sent to the high-level language of one group of translater 15a, 15b, 15c, a preference pattern output that is sent to Data Matching device 16, and an interface type message that sends to interface module 19.Translater 15a, 15b, 15c are consisted of, and the high level instructions that conversion receives from universal command generator 14 is on form and the instruction of corresponding switch type A, B or C compatibility.Data Matching device 16 receives from the preference pattern data of universal command generator 14 and compares these data and the data that are stored in the memory 17, so that the switch of selecting this instruction to send to.The data that are stored in the memory 17 can be in response to upgrading by the input signal of monitor 13 from network N.

Fig. 3 and 4 is illustrated in the layout of data in the memory 17.

Fig. 3 represents that type by geographic area and switching equipment is for the storage data of switch A 1, A2, B1, B2, B3 and C.As everyone knows, these are intrinsic characteristics, and memory 17 can also be preserved the data when precondition with respect to respective switch.

Fig. 4 is expressed as the similar inherent data of every link (1 to 10) maintenance of system.These data comprise the capacity of each tip node and every link.

For every type switch A, B, C are provided with command generator 18a, 18b, 18c.Command generator 18a, 18b, 18c receive data via interface module 19, corresponding translater 15a, 15b, 15c from adaptation 16, clock 11, produce instruction from this command generator, are used to send to the suitable parts of network N.

Each instruction can send immediately by command generator 18a, 18b, 18c, or is sending on some preset times under the control of clock 11.For example, each instruction can be sent to network N regularly, such as with cry into what day of a corresponding to preset time of the airtime of TV or radio broadcasting and a week.

Interface module 19 guarantees to require the universal command and all switch compatibilities that comprised of two or more switch cooperations.Interface module 19 control command generator 18a, 18b, the 18c operation in the compatible incompatible incident of desired instruction and switch A, B or one or more types of C.Such incompatibility will be discerned by corresponding translater 15a, 15b, 15c, and this translater sends an error message to interface module 19, points out that this instruction is inexecutable.Universal command generator 14 sends an interface type message to interface module 19, the operation of control command generator 18a, 18b, 18c.Interface type message can be one of three types:

1) AND: the instruction that is addressed to all switches must be the instruction that can carry out; If any switch can not be carried out, then this instruction can not be sent to all switches.

2) OR: instruction and these switches of being addressed to any switch can be carried out this instruction really, even other switch can not be carried out this instruction.

3) COND IT IO NAL: an instruction of controlling route between each switch is executable with respect to more such routes only, and the route of controlling for more such all switches of routes is and this instruction compatibility.

A message is sent to man-machine interface 12, indicates whether that to a certain degree, this instruction can be performed.

The operation of network manager M is described now with reference to Fig. 1 a and 2.In this illustrative example, be duration of a call with controlled function, this function is the time is set or is activated in response to an overload condition that is detected by monitor 13 at weekly one.For the cause that illustrates, will suppose, and the equipment of type A can not provide the duration of a call function only for the switch request duration of a call in geographic area X and Y.

People's operator provides one to be input to universal command generator 14 by man-machine interface 12.This input identification desired function (duration of a call), by the ratio of duration of a call, the geographic area that is capped (being regional X and Y in this example), (for example come into force with the time that is operated of this function until manual deletion, or from 1900 to 2030 each Tuesday, or in response to the detection of monitor 13 such as an once external excitation of overload).

The universal command that produces at generator 14 is sent to the storehouse of translater 15a, 15b, 15c, and it is a kind of by corresponding switch system type A, the manageable form of B, C that its each translater is translated this instruction.In this case, type A can not carry out duration of a call, thereby produces an error message by translater 15a.

Universal command generator 14 also will have two outputs.At first, it sends choice criteria to adaptation 16.In this case, the switch that will carry out duration of a call is selected by the geographic area.The selection of the setting of selecteed each switch can be carried out according to the internal structure of network, and for example, a kind of setting can comprise a DMSU (digital main crosspoint) and its sub-DLE (digital local switch).Another scheme, being provided with can be by manual selection, so that satisfy the standard of non-inside, such as the area of coverage of TV station, the perhaps given directorial area of utility company.These standards compare with the detailed data that is stored in the storage in the memory 17 in adaptation 16, and the identifier that satisfies each switch of this standard sends to command generator 18a, 18b, 18c from adaptation 16.In the present example, the identifier of switch A 1 and A2 is sent to command generator 18a, and the identifier of switch b 1 and B2 is sent to command generator 18b, and the identifier of switch C is sent to command generator 18c.The identifier of switch b 3 is sent to command generator 18c, because it is in the Z district, does not therefore satisfy geographic requirement.

Relate to the type of instruction and be sent to interface module 19 from other output of universal command generator 14.Whether this output recognition interface module 19 is performed to this operation part, even some switch lacks necessary function.Under the situation of duration of a call or call congestion, operation can in this way partly be carried out, interface module 19 sends the instruction that produced by translater 15b and 15c to corresponding instruction generator 18b and 18c like this, but instruction is not sent to command generator 18a, because only error message receives from translater 18a.

Unless universal command can not be transmitted if all associated switch can be cooperated, from reaching of translater 15a, 15b, any one error message of 15c, prevent that interface module 19 from sending any any command generator 18a, 18b, 18c of instructing.

If universal command requires to fail to set up in first switch with desired function and the route in the middle of second switch with identical function, but this does not influence first switch and is established to the route of other switch according to this universal command, provides these other switches to have desired function.

The instruction that produces at command generator 18b is sent to switch b 1 and B2 and the instruction that produces at command generator 18c is sent to switch C1.Under the control of clock 11, on the time by 14 layouts of universal command generator, each instruction is carried out transmission.

Therefore, by by people's operator's single instrction or by the automatically defeated people of monitor 13, desired function can be carried out by the replacement part that in the geographic region of defined all have a suitable function, and the operator who does not need the people is every kind of independent operational order of switch type on demand, or controlled switch is wanted in special identification.

In the arrangement shown in Fig. 1 b, system is formed like this, the overload that unsuccessful call attempt from forming even signaling network 31,32,33 prevents.Call set-up signal transmits on signaling network 31,32,33, so that setting up necessary connection between switch A 1, B2, the B3 in traffic network 4,9,10.The number translation device TX of user 23 in signaling parts T is carried out the number translation service.In other words, user 21,22 can utilize a special number (for example toll free number) calling party 23, and this particular phone number is the calling that is established to user 23 by the control signaling parts T of translater TX translation.

If utilize the overload of the calling of special number to be shown or predicted come out, network manager M can control switch A 1, B2, B3 no thoroughfare that signaling network 31,32,33 sends a call request to this number.So not only alleviate traffic network 4,9,10, and alleviated signaling network 31,32,33.If one of respective switch (for example A1) does not have the ability of the request of forbidding sending to this number, then this request still can utilize network manager M to be under an embargo in signaling parts T.Do successfully to prevent like this, but such doing can prevent that them from propagating by the remainder of network in the call request between switch A 1 and signaling parts T on the signaling link 31.

Present normal sequence with the descriptive system operation.The normal sequence of this operation can be regarded as being made up of three different disposal: control definition, control are arranged and control is implemented.At first, the user utilizes control (PPC) and the operation Control Parameter and the controlled target of control types (for example, definition duration of a call) the definition planning in advance of regulation.

In case after the definition, this PPC can be stored in the traffic that is saved in this network and control database 20, so that use later on maybe can be arranged.

The major function of database 20 provides the command list REPER TO IRE of PPC, and relating to this command list of each network problem can be retrieved rapidly.

PPC can define to control and arrange to be retrieved in database 20.The user provides from database 20 and one of to select to arrange the details of a PPC and regulation arrangement and also can add controlled target and Control Parameter (if they are not to be defined) if desired, perhaps changes (if they are defined).PPC is unaffected in database 20.In case arrange, control can enter the table of present arrangement control.

Each control of having arranged can be authorized for certain during any in enforcement N minute (N is predefined parameter here) of their expections, can not implement otherwise control.Do not provide if authorize in the predefined time, then produce a report by the N regulation.

According to the arrangement that appends on the PPC, (insert and remove) automatically implemented in the control of mandate.The user can monitor the process that control is implemented in real time.

Network traffic is controlled database, and 20 permission users set up and the command list of maintenance PPC.This makes the user save time by the control (for example relating to overload) of visiting public use, only is the controlled target difference in this case.It also allows the accurate enforcement of the complicated control sequence for preparing.Require to improve with the network problem that accurately disposes some controls rapidly.Database 20 can also be used as a kind ofly sets up the source of new control from it.

There are three kinds of database entries:

1. basic PPC (utilizing a single switch/route controlled target)

2. basic PPC (utilizing a switch that controlled target is set)

3. Lian Jie PPC

Each controlled target can be prescribed, and perhaps can be saved for the user to select.The PPC of a link comprises a series of PPC.Each PPC whole or only some of Control Parameter and controlled target space can be stored.Because when arranging PPC selected, network manager will be checked a PPC who is stipulated comprehensively.

The basic PPC with single switch/route as a controlled target is the simplest type of control.The basic PPC with a switch setting as controlled target also is called broadcasting control.These two kinds basic PPC types only are differentiable when controlled target is prescribed.

Broadcasting control is a kind of control that is applied to a plurality of switches (exchange apparatus).Be provided for defining and keeping the data of database of each exchange apparatus.

The PPC of link is a kind of compound control and is to link the PPC that some basic PPC form link together with sequence form.When the PPC of link was implemented, each PPC in chain implemented in proper order from first.

Respective switch can be organized as group of switches.The definition of the group of switches of public use can be stored in memory 17 neutralizations and use when limiting broadcasting control.

Public branch exchange can also utilize switch type to be organized as the dynamic exchange unit.Following default dynamic exchange unit is provided at here:

● all DMSU (digital main crosspoint; Main convertor)

● all DCCE (digital call center switch; Tandem/repeater exchanger-intergrade other)

● all DLE (digital local switch)

● all DDSC (numeral derives and serves switching center)

● all DJSU (digital tandem crosspoint-intergrade other)

● other switch of subordinate level of all DMSU (one group of every DMSU)

● other switch of subordinate level of all DCCE (one group of every DCCE)

Other switch of subordinate level that comprises DLE, DJSU and DCCE.

A traffic is controlled a specific problem that is arranged to handle on network.When arranging, the user has two sources for PPC, promptly is stored in the PPC of network traffic in controlling database; Or, allow the user promptly to arrange new control by defining the control of this purpose, need not follow normal sequence and any retrieval of the control qualification that is stored in the database.Network manager will be carried out the same sequence that exists, but this is transparent for the user.

Network traffic control is used in the switch in the mode of two-stage.The data equipment that it utilizes network traffic to control database defines, and this is arranged in official hour and will be employed.Control can use immediately or be stored for later application.

Single and repeatedly (repetition) two kinds of arrangements are provided:

The situation of single only comprises an insertion (and removal)

Situation repeatedly comprises a plurality of insertions (and removal).

Each arranges control to name by this way, and as special event, for example the Christmas Day links them.

Arrangement can be stipulated in the mode of not removing the time.

Single mechanism regularly provides the chance during defining, and traffic control will be employed during this period.This utilizes control insertion time and control removal time to realize.

Fig. 5 provides the explanation of the scheduling-type that may utilize the single arrangement.The dashed region representative is the time that applies control during this period of time.On behalf of application time and ' R ', ' A ' represent the removal time.Control can be arranged under the situation of not removing the time, and a kind of like this control is that indefinite duration is effective.The removal time of this arrangement that some data are attached to the back is provided, and it also is possible removing immediately.

The control insertion time is the time according to the rules, and for example, 10:30 14 NOV 94 stipulate.

The control removal time, for example 13:15 14NOV 94 or it can be used as Delta Time (that is, the control duration) with the format specification identical with the insertion time, and for example, 00202.45 form is stipulated.

Delta Time in this example means removed control after 2 days 2 hours 45 minutes.

Repeatedly (repetition) arrangement is a kind of single arrangement, but has additional arrangement start and end time and some repetition standard (for example, weekly).

Repeatedly the data of An Paiing provide and have limited a kind of chance that traffic control applies pattern that repeats.The pattern that applies is by following project definition:

Arrange the beginning data;

Arrange end data;

The control insertion time (within during the arrangement start and end time regulation);

The control removal time (within during the arrangement start and end time regulation); With

The repetition standard.

Fig. 6 provides and can utilize the explanation of repeatedly arranging a scheduling-type of realization.The dashed region representative covers the time that applies control.Might make apply control during cross over midnight border (that is, control is removed and appeared at the different sky that inserts control).When relevant arrangement expired, control was removed.

Note, until arranging time started SST control just to begin and arranging concluding time SET control to be removed, though these times must not insert with control and the removal time is consistent.

Arrange time started SST, control insertion time A and control removal time R are with the same format regulation of above-mentioned single control.

Arrange the concluding time to determine after this time, no longer to apply control.

Arranging the concluding time is to remove in the time format in the control of afore mentioned rules to stipulate.

The repetition standard is according to following every definite:

What day of one week, or each day in January (but can not both simultaneously) and

Each calendar month in 1 year, these months are used above.

Under the simplest situation, repeatedly arrange one of regulation arrange the week that start and end time and control inserts each day or month each day and in arrangement start and end time of regulation, remove control.

Can stipulate more complicated repeat pattern according to top, promptly arrange each month in start and end time by further being identified in regulation, wherein control is inserted and control is removed in these times.Have to be arranged to automatic expiration, or just operate by the operator and to force expiration.

Under the situation that single is arranged, be arranged in automatic expiration when removing.For repeatedly arranging, arranging the concluding time that automatic expiration takes place.

After the control from network traffic database 20 was arranged, network manager kept the details of being arranged and will implement control according to the rules in arrangement.

Provide data to allow usertracking and monitor the current table of the arrangement control in network manager and monitor which arranges control to implement (operation).Fig. 7 represents to arrange control how by arranging control and operation control table to be followed the tracks of by network manager.

Arranging control to apply in the incident of failure, this applies by the periodicity retry, until success, or the concluding time in the cycle of arrangement reach.The number of times of retry and retry interval can constitute each parameter.

After having reached in maximum times that retry is attempted or during arranging,, then send to 12 1 message of man-machine interface if network manager still can not be realized arranging control.

Arrange the realization of control to lose efficacy owing to some reasons.At first, may be to arrange inconsistent or other reason (fault in the network manager) of request.Secondly, may be communication failure.

Might be various communication failures also, safeguard fault (for example, handling the fault of a work request), or exchange fault (for example, switch can not receive the control request of automatic network).

Under preceding two kinds of situations, network manager will continue to apply retry logic according to the rules, so that successfully realize control.But under the situation of exchange fault, as long as switch has fault can not receive control request, network manager will stop retry logic.

Overload arranges can be allowed to accept any traffic control code fo practice that defines in network manager, as following described.

Before control request was implemented, if whether the network manager inspection exists and an existing control is arranged on the controlled target and have, then the working control request of being sent by network manager was modified.Following predetermined rule is the general rule that will be applied in when implementing control.

Before applying control, network manager can send real-time " state of a control an is read " request.

In order to insert basic PPC (single switch/route and group of switches), network manager is checked the control (member that may comprise a group of switches) of same type on this target.If, then arrange control not to be implemented, otherwise arrange control to be implemented if the control of same type has applied and arrange the arrangement of control to produce the date early than the control date that is applying.

The arrangement that the user can stop being authorized to before enforcement is controlled.The control that is terminated can continue to recover at any time, if but the insertion time that should arrange over and done with, then can't implement this control.Repeatedly be controlled at and recover to be implemented until the next one time of inserting later on.

Basic PPC (single/switch/route and group of switches) is preceding inserting, and real-time state of a control is read in the request of can sending of Control Network manager.

If control is implemented on switch or the switch resource that existed, but utilize different parameters to implement control, then send the switch-specific command of " variation ", otherwise send the switch-specific command of " insertion ".

Network manager can be arranged like this, to such an extent as to if its finds the control of same type and detect the control that it does not insert this discovery that then network manager is alarmed each user, upgrades to control database and send the mailbox of a message to centring system.If consistent that Access Privileges (Control A uthorisa tion access privilege) provide authorized in customer-furnished then and control, then arrange control to implement, otherwise will be removed.

When removing a basic PPC (single/switch/route and group of switches), the arrangement control of network manager inspection (each member that can comprise a group of switches) same type on target.If the control of (but owing to apply above-mentioned first rule, referring to Fig. 7, not being implemented) that the control of same type is arranged and will implements utilizes the second above-mentioned rule to apply.

If do not have the control of same type to be arranged and owing to will implement, implement one remove control request before, network manager sends a real-time state of a control and reads request.

If control implements on switch or this resource exists, then send one and recover switch-specific command.

Each control for the pre-planning through linking if the enforcement of former PPC is successful, then will be implemented in each PPC in the chain.The enforcement of the PPC that forms in chain will be carried out according to top each rule to the PPC regulation.The removal of PPC in chain is the reversed sequence that they are inserted into.

If one of PPC that forms lost efficacy between implementation period, then in chain before all the effectiveness of the composition PPC of enforcement will be retained.

The arrangement control that has been authorized to is implemented on each time of regulation by network manager.On the point of implementing, the network manager conversion general is controlled to be the special-purpose control of a switch, if general controls is the control of a link, when each independent control was implemented, each independent control was transformed to the switch professional format in the control of this link.Network manager arrives suitable command generator 18a, 18b or 18c and preserves corresponding one or more control responses of being returned by command generator 18 for each switch sends one or more control request then.At last, the new state of a control of network manager utilization is upgraded the internal control database.

In general, a control can be inserted into, removes or delete.In addition, can send state of a control and read request, before network inserts or removes a control, can obtain each state of Internet resources.Removal request is not the result to any control request of network communications manager.

Each control response and each control request are complementary, and form one and control the internal affairs processing completely.Each internal affairs is handled corresponding to an insertion of the control of an arrangement or is removed.

The network traffic manager sends instructions to a switch (through network communications manager) and goes to revise respective switch resource (for example, by producing the traffic that will reselect route) to overcome the purpose that just is present in the variety of issue in this network.

The resource group that each device type (for example X of system phase place 3) management is different is carried out its swap operation.But network manager attempts to utilize the intention of revising traffic pattern in a similar fashion to be modified in switch resource on the different switch device types.

In order to make network manager carry out co-operation and to allow the supplementary equipment therefore type to be increased with some switch device types as the composition of system, but being become, system do not become increasingly complex, defined the switch type of one group of independence general controls.

The control of some switch-special use only appears in the specific equipment or in this common group of not packing into.Data, arrangement and the control of the generation of these non-general controls can be provided, make the special feature that only proposes, or can not lose for making the uncurrent spirit of as a whole system for a kind of special designs of specific (special) requirements of arrangement specially by a system.

Each general controls that is stored among the network manager M has the parameter group of a definition.When arranging control to be implemented for one, this controller sends the special-purpose control request of switch to network components.Translater 15 is via one group of transformation rule, and conversion is stored in the switch private variable of general controls for working as in this enforcement in the network manager.

When the user produced a purpose telephone traffic control (Destina tion Volum e Control) such as call congestion, the network manager storage was for each value that is used for general parameter of controlling definition and be not the value that is used for this switch special parameters.The switch special parameters was calculated according to one group of transformation rule on the enforcement time.Require an independent rule group for each target device type.

Can not distribute each default value by network manager from the switch special parameters that general parameter calculates or derives.But, if known target or each target that comprises the control of each switch with additional function of universal command that the user produces then for the switch special parameters, such as traffic category and call arrangement, can be stipulated at the control generation time.

Transformation rule is that the special control for each switch defines on each target device type of being supported by control M.

In the conversion general parameter group is in this switch special parameters group, if evaluation cannot obtain, conversion process will be utilized the nearest usable levels for the special parameters of a switch.

Non-general controls can be stored and manage in network manager with its switch dedicated form such as the loop feedback of the X of system.In the enforcement time, carry out non-conversion process by network manager and be sent straight to the respective switch that is used to implement in exchange with each control details.
