Description

Telecommunication switching system particularly telephone switching system circuit structure and produce the method that telecommunications connects
The present invention relates to the circuit structure of telecommunication switching system,, and connect according to the telecommunications of the preamble of claim 13 particularly according to the telephone switching system of the preamble of claim 1.
From Deutsche Bundespatent P39 21 637.3 a kind of circuit structure of switching system as can be known, can randomly connect mobile subscriber station in the switching system, this circuit structure by subscribers feeder or by with several exchanges in a people of a user (subcriber-individual) wireless connections be fixed on a certain position with respect to related exchange office.Herein, not in all terminal stations, all to store the item of information of specifying home location registers, each situation of existing each subscriber station of this register pair is responsible for.For each terminal station, memory is equipped with, only store in the memory and specify in which subscriber station item of information continuous under each situation with relevant terminal station.In addition, dispose corresponding memory in middle exchange, item of information is stored in these memories, indicates which subscriber station and just is being connected to which unique terminal station that is under the jurisdiction of this hierarchical structure at present.Known exchange makes and can reduce to be provided with the exchange complexity that telecommunications connects.The complexity that reduces to exchange realizes by the following fact basically, promptly, during setting up the telecommunications connection, needn't transmit the searching message that is used for desired B side by entire switching network, but searching message is handled by the intermediate office of next layer structure higher level only from origination terminal office and only when needed subsequently.
In above-mentioned German patent application P 39 21 637.1, suppose that not only traditional subscriber station but also mobile subscriber station that is lead connects all for good and all is assigned to terminal station.
Can learn a kind of circuit structure, particularly individual layer net of communication switch system or the telephone switching system in the multilayer net from German utility model G 94 04 477.5.In the network, dispose first switching system on the first low layer of structure, if necessary, second switching system, the subscribers feeder that at least also dispose on the second higher layer of structure can link to each other with first switching system.Under each situation, in the multilayer net, the switching system on the higher layer of structure links to each other with two switching systems on being arranged in following layer of structure at least.Each switching system to network distributes a memory, item of information that can all subscriber's line addresses of storage networking in the memory.Circuit structure of a configuration under each situation in first switching system, this circuit structure shows as a processor that contains control program.This control program designs in such a way, promptly, be subjected to place, designated user station that the triggering of the message of no user is arranged, and this message is imported at the subscriber station place, and this subscriber station is any one subscriber station in the network, so just produce and indicate the address information item of this subscriber station circuit address, and be input to delegation's relational storage of distributing to this user.In containing the network of at least one further layer of structure, start the generation of the information that indicates the switching system on the low layer of structure and item of information is input to the line storage of the related exchange system assignment of further layer of structure to this user.Although this circuit structure of learning from German utility model G 94 04 477.5 can be assembled into the existing switching system, perhaps realize by the personal computer that can be connected to switching system from the outside, but the process of carrying out is complicated, and relates to the single or multiple lift network.
According to this prior art, the present invention is based on such technical purpose, promptly, provide the circuit structure and the method for the sort of type that this specification provides at the beginning, even make when linking to each other, also the method for salary distribution that subscriber station can be dispensed to the terminal switch system changed arbitrarily with other network.
According to the present invention, this purpose is to realize by the feature that provides in claims.
Feature of the present invention has many advantages.
Can be so that all there be global availability in employing the user in the working range of foreign country's (" second ") network N 2 (Fig. 1) according to circuit structure of the present invention and method.
These advantages are to realize according to the circuit structure of German utility model G 94 04 477.5 fully.Therefore, can realize complete ambulant purpose, promptly each subscriber station can link to each other with each terminal switch system, and comparatively speaking, only takies a spot of memory capacity in switching system.For example, suppose to have in the network 3,000 2 hundred general-purpose families, in this network, adopt according to circuit structure of the present invention, the memory that in each terminal switch system, only needs about 1.2 Mbytes so, even the terminal switch system provides about 65,000 users' access (subscriber access) (resident family/office unit).Each user for network provides 1, and for example needs 2 bytes in the actual user's who occurs the position memory in this terminal switch system.On the higher network layer of the next one, having length is the location register satisfied user's who occurs here the requirement of 1 byte, and the terminal switch system number that needs only to the switching system service on next higher level is not more than 255.On higher network layer, if be no more than 15 switching systems for the switching system of next lower level, then each switching system has the address register of nybble can satisfy the demand.
Further advantage is, compares with the circuit structure among the German utility model G 94 04 477.5, can not increase to set up the exchange complexity that telecommunications connects.Also reduced the process that is in respectively in the circuit or in the computer and be used to manage the required memory of corresponding data according to circuit structure of the present invention and method.Owing to separate according to two discrete memory blocks provided by the invention, presence bit bar (presence bit bar) (AWL) and so-called position field (Location field) or location register (LR), containing 100,000, in 000 user's the network, need the memory space of 12.5 Mbytes for the presence bit bar, so as management add up to this customer volume all have data.Comparatively speaking, because for example average only all users of 1/2000 must obtain management in having the network that is higher than 2000 exchanges usually, the position field number is less relatively.Experience shows that in local network, what mainly carry out is local call, is subjected to the user's of local position territory management mobility also to be confined to this local zone.Therefore, as rule, can be in position field (LR) data of local management relatively complicated (comparing) with presence bit bar data.Have only an exception, that is, when a certain user's position when Mo Nihei changes to the sweat fort, just need to change in the position field data interval censored data (inter-area data).
Unusual advantage is in another practice, is to the switching system of next higher level or the interior judgement in zone that remains on himself has a program to make with call-delivery.Therefore, adopting low-down dynamical system to load according to method of the present invention manages.The switching system number is many more in the network, and this advantage is obvious more.

Therefore, only must with relevant network of relation partly in (message IT1) user's of current existence place on line information stores in memory S1, S21, S31.
As describe with shown in Fig. 1, under each situation, be respectively processor C1 CPU, C31 CPU and C21 CPU according to circuit structure C1 of the present invention, C31 and C21.
Processor C1 CPU is relevant with control program, the design of this control program is as follows: be subjected to the triggering of message IT1, this message indicates subscriber station (for example T1) and locates having or not of user, and message IT1 is in this subscriber station place input, and it is relevant with any user of network, so produce the address information item of the place on line that indicates this subscriber station T1, and this item of information be imported into this subscriber-related relational storage S1 of delegation in.
In network with at least one back one architecture level, the generation of log-on message item IE1, this information is to the switching system E1 that indicates lower layer of structure, and relevant, and this item of information IE1 is input to the line storage S31 of the Z31 of related exchange system of a back layer of structure of distributing to this user (being second layer of structure in this example) from the bottom with subscriber station T1.With reference to Fig. 4 and Fig. 5 this process is described in more detail below.
The invention still further relates to circuit structure SML1, SML2, under each situation, they are concentrated and are arranged in the network, and link to each other with all switching system Z11, Z12 of network top structure layer.This circuit structure is a kind of controller SML 1 CPU, it is relevant with the control program of design in such a way, promptly, trigger by message IT1, this message indicates having or not of the subscriber station T1 user of place, at this subscriber station T1 place input message IT1, and check this user to adopt the report user's of visit T1 checking.If the result of this check is positive, then the circuit structure C1 among the circuit structure SML1 order switching system E1 produces the address information item of the place on line of this subscriber station of expression T1, and be entered into and the memory S1 of the line correlation that this is subscriber-related in.In network, produce the item of information IE1 of the switching system E1 of the lower layer of structure of expression with at least one back one layer of structure, and with this item of information be input to should be user-dependent after among the line storage S31 and later each memory of the Z31 of related exchange system of a layer of structure.
According to circuit structure C1 of the present invention, C31, C21; SML1, SML2 can form with an outer computer (preferably people's computer) one by one, and this computer links to each other with each switching system.
What Fig. 4 and Fig. 5 described is according to the structure of circuit of the present invention and the functional structure of circuit.This structure is described below.
As shown in Figure 4, can have computer to form according to circuit structure C1 of the present invention, this computer links to each other with a switching system from the outside, and switching system has for example at least one signaling interface module I NI, INI ' formation.By this signaling interface module I NI, exchange signalling information between computer and switching system.Computer relevant with memory S1 (Fig. 1).In described embodiment, computer is one first memory block AWL, the second memory block LR, the 3rd memory block CLR/LST and the 4th memory block (main storage area) AS.
In the first memory block AWL, can storage representation there be user's first information item at present.In the second memory block LR, second item of information of place on line that can the current subscriber station T1 that can arrive of storage representation predesignated subscriber.In the 3rd memory block CLR/LST, the 3rd item of information of switching parameter that can the storage representation predesignated subscriber.These parameters comprise: authorization information, interface agreement, equipment disposition (fax, phone) etc.
Fig. 4 also shows circuit structure C1, and this circuit structure is a processor C1 CPU, and it in an illustrated embodiment, with directory number (directory number) register RR1 ..., RRn is relevant, register RR1 ..., can store the directory number that the calling subscriber dials among the RRn.
Except directory number register RR1 ... beyond the RRn, give among the memory CPU and have list notation ALM, decoder DC and label information register MR1 ... MRn.
Particularly, the control program of C1 CPU processor is design by this way also, that is, (first and second items of information of storing among the first and second memory block AWL, the LR are updated for IT1, triggering IE1) to be subjected to message.So, the new address information item of input in the S1 memory, and delete old address information item.
According to dynamic loading and memory requirement, processor (CPU-CPU) is made up of one or more processor chips.The memory block in " startup " and " reinstalling (reload) " stage when hard disk HD, HD ' break down as the backup of memory of program with in system.But, other back-up storage mechanism also can be provided.
In order to ensure the highest possible availability (availability), all facilities are with double (C1 CPU, C1 CPU '; S1, S1 ') provide.Under normal working condition, equipment packing into-work under the shared model, that is, each CPU (C1 CPU, C1 CPU ') handles 50% the call request that occurs.
Interface circuit INI can connect as standard module by 64-kilobits/second digital signal line, and adopts the standard CC S7 signaling protocol of private branch exchange or adapting system.Their number is to select according to the total service request in the busiest time.
(C1, C31 C21) depend on the size in action (action) zone especially according to the quantity of user/personal phonebook's number of circuit organization management of the present invention or path/circuit search module.If operating space is Germany for example, need 100,000,000 directory numbers to satisfy the requirement of user, function and service access so.
In the system that contains according to circuit structure of the present invention, what personal phonebook's number referred to is not place on line (normally used position (shelter/office)) or user's current location, thereby the path of using in the prior art/circuit method for searching is to not be used in to comprise according in the system of circuit structure of the present invention.
Because address (place on line) no longer is the part of calling the book number, the address is stored-can change-pass through destination and subscribers feeder in the path selection system by the user.In according to circuit structure of the present invention, as shown in Figure 4 and Figure 5, this finishes in the first and second memory block level so-called presence bit bar AWL and so-called location storage district LR.
In having the switched telecommunication network of 100,000,000 directory numbers for example, each directory number is to represent that with 1 in first memory block (the presence bit bar AWL among Fig. 4 and Fig. 5) promptly, memory requirement is 12.5 Mbytes.Second memory block (location register LR) has in different network layer (Fig. 1 and Fig. 2) with the different and different length of situation one by one.This heap(ed) capacity by user/port of different Route Selection branch (branch) numbers and for example user capture exchange (subscriber access exchange) OVSt determines.
(see figure 5) in the example of selecting, the field length (LR-ZVSt) on the ZVSt level (level) is 1 byte, 3 are used to identify adjacent ZVSt, and 5 31 extension sets that are used for mark main exchange (HVSt).
If 15 extension sets or Local Exchange (OVSt) in each situation lower area exchange (KVSt) are enough to be used in sign, then the field length (LR-HVSt/KVSt) on the HVSt/KVSt level for example is 4 (nybbles).
Being used for current each user that can arrive by means of its personal phonebook's number can addressing, and then field length (LR-OVSt) just no longer is on the OVSt level.In field length is under the situation of 16 (2 bytes), and each OVSt has 65,000 users approximately.
Path/circuit search is made up of two routines basically.In first routine, that caller (A) side dials and be stored in directory number register RR1 ... directory number among the RRn is used for reading position relevant with this number among the first memory block AWL.
Under the situation of " zero input ", by flag register MR1 ... MRn wherein, is delivered to telecommunication system with the corresponding relay group number, starts the direct switched connection with next higher network layer.
If in the corresponding positions of first memory block (presence bit bar) AWL, import 1, promptly, in the current exchange area that is in private branch exchange or switch in called (B) side, then adopt directory number register RR1 ... the number of storing among the RRn, adopt second routine to come mark to be somebody's turn to do (B) side by means of decoder DC, and the label information that will be stored in this second memory block is read (Fig. 4) among the working storage AS.
This label information is converted into a numeral, and this numeral is used for selecting port or relaying group by switch usually, and is forwarded to flag register MR1 ... MRn.This label information is from here by being used for being forwarded to private branch exchange or switch by the signaling interface module of the exchange that continues.
Just as will be descr, just finished according to the setting/deletion that has input item (presence entry) of user/personal phonebook's number of circuit structure of the present invention.
Employing makes that according to circuit structure CIGE of the present invention the interior user in work (action) district of (" second ") network N 2 has global availability (Fig. 1) abroad.As described in, for example relevant with equipment I GE (international tandem exchange) circuit structure is a processor CIGE CPU, it is relevant with the control program of design in such a way, promptly, be subjected to message IT2 to trigger (Fig. 1), this message indicates in second network N 2 subscriber station (T22) and has located no user, at this place's input message IT2, and the user-personal phonebook's number that comprises user in first network N 1, then produce the address information item of the place on line that indicates this subscriber station T22, and be input to memory SIGE.
The length of location register has the length of 6 bytes among the memory SIGE, thereby can store the nearly overseas call book number of 12 numerals.In addition, adopt the maximum number of user of global call transmission for example to be limited to 10% simultaneously, remain in the limit range so that will be used for the requirement of the storage space of expanding location register by circuit structure CIGE.In this example, suppose not have in second network and be higher than 10% user and adopt this feature simultaneously.Yet the present invention is not limited.
When 100,000,000 users have the duplicate numbers (PR) of user-phone book number, then provide memory span 100 * 0.1 * 6 bytes=60 Mbytes.In order to be independent of each dialing and the method for numbering serial of foreign country (" second ") network N 2, " locking (lock-on) " in second network N 2 and circuit method for searching can be designed to national (" first ") network N 1 in different.Describe in this example below:
During " locking ", the user is for example in Spain, from the hotel, holiday villa or its shelter, the subscriber station T22 from foreign country dials:
07 49 013X IGE=international exchange bureau fetcher codes
The CC=country code
The service indicator of IGE CC SI=locking
By dialing above-mentioned directory number at subscriber station T22 place, the user oneself provides the path (country code of Germany is 49) of path/circuit search module CIGE of the IGE equipment of his country of visit to it, and this module switches to transparent mode (transparent mode) with second (foreign country) network N 2, so that irrelevant with specific country's restriction.
In the step afterwards, the user dials from the visit (T22) of second network N 2, and in selected example, so-called " calling line sign " composition (CLI) is:
34?66470351
CC CLI=calling line sign
=country code
Opposite with the situation of country's " locking ", can be made up of and the calling line sign mostly is 9-10 digital whole directory number most and is stored in location register (SIGE memory) the numeral that 2-3 is used for country code, this register is expanded to 6 bytes in the path/circuit search module of international exchange bureau.
Then, the user visits T22 (second network N 2) input his the personal phonebook's number PR from first network N 1 from foreign country, and for example 89573214, and his PIN code if possible.The latter is used for checking authenticity, has therefore started his location register that contains complete foreign access number.
Finished in (" first ") network N 1 after his the previous place on line deletion,, arrived his visit exchange (OVSt) by the 3rd exchange level (ZVSt) from the international networks level.After this process, can find zero input item (zero entries) among the path of any one in first network/circuit search module C1, C31, the C21 (Fig. 1) under his number.
From at this moment, each telecommunications of this user who enters in the SIGE memory continues and finishes by the ZVSt level in the international office being independent of its starting point, and then, can number set up according to storage in the location register and the world of distributing to this number and foreign networking telephone book number and continue.
The user can also switch to the directory number that adds innings phone number and facsimile machine second network (for example holiday point place), on his dedicated phone number of being added to.Thereby have such advantage, when the user appeared in the service area of second network, the user also can occur in several modes.
Because as the call charging benchmark, the more shortcoming of high call cost will can not appear in the calling subscriber with the calling party.Like this, callee's responsibility is whether he carries out or how long carry out such calling, that is, this calling under normal circumstances is to carry out under local rate, and under the rate he is chargeed abroad suddenly.Therefore, can introduce the stand-by period, he can make decision in waiting time.
As described below, as Fig. 1,2 and 3 shown in respectively like that, in network N 1, N2, set up telecommunications and continue.
Programmatic telecommunication switching system E1, Z31, Z21, Z11 is relevant with control program, this control program designs by this way, that is, (A is T1) to the second subscriber station (B from first subscriber station setting up, during the continuing T6), from (relational storage (S1) of this switching system is checked in A, T1) relevant switching system (E1) beginning with first subscriber station, see and whether have relevant second subscriber station (B, the information of place on line T6).If check result is sure, then set up directly and second subscriber station (B, continuing T6) according to the content of memory (S1).If the result who checks is negative (zero input), then carry out and the continuing of switching system (Z31) of next higher layer of structure.In this switching system (Z31), check relational storage (S31), see whether have relevant second subscriber station (B, the information of place on line T6).If check result is sure, then carry out with this memory (S31) in the continuing of switching system (E1 ') of sign.If check result negates, then set up and the continuing of switching system (Z21) of next higher layer of structure.Like this, by several switching system (E1, Z31, Z21, Z21, Z11, Z23, E4) (B, the first circuit structure CIGE (Fig. 3) that imports of place on line T6) carry out and second subscriber station (B, continuing T6) relevant with arrive this layer of structure or arrival and the international equipment I GE of tandem exchange with incremental order relevant second subscriber station that finds.According to this input, continue further with the order of successively decreasing from relevant layer of structure to another layer of structure, arrive the switching system (E4) of minimum layer of structure downwards, at this minimum layer of structure place, (B is T6) in current actual being connected " first " or " second " network (Fig. 1) for second subscriber station.
The invention still further relates to a kind of by subscribers feeder or can be with subscriber station T1 by radio link ... be connected to the method for each related exchange system (for example E1) of minimum layer of structure.In addition, can also be created in the access path that exchange that each layer of structure place replaces the network of himself produces foreign network (preferably mobile radio telephone) exchange, the result is that to become user in the all-network be useful for one and identical personal phonebook's number (PR).
In addition, can be used in public network or private network according to method of the present invention and be used in similar system and the private branch exchange.
For simple as far as possible in the user in the switched telecommunication network of the above-mentioned type operation and utilize advantage with the access to netwoks of location independent attractively, circuit exploitation by means of terminal shown in Figure 6 (subscriber station), utilize SIM (subscriber identity module) chip at the Any user line place of network N 1, N2, can produce respectively and deletion exist input item (presence entry) (IT1, IT2).
As mentioned above, the subscribers feeder of the reality of numbering in the switched telecommunication network no longer disposes according to circuit structure of the present invention, but the user of each registration for example receives his personal phonebook's number (PR) of going up input at chip card (SIM).Because this fact, number of users, and in principle is that any amount of user can appear at a subscribers feeder place (for example, 4 people's shelters, and several visitors can be arranged) now.
By chip card, the user can notify the position at its place to network.For example, this can finish by Terminal Design shown in Figure 6.
The dial of user terminal (phone) also has 6 special keys (2-7) except 10 numerical keys (1-0) as shown in Figure 6, and two keys (3 and 4) wherein are used for the special function of device, as attempt redialing to last call.On the contrary, according to the present invention, in ISDN terminal with adopt under the situation of analog access of multifrequency code (MFC) dialing, key 2,5,6 and 7 is taken by character combination, and this makes that the user can access switch (OVSt), thereby differentiates between several functions inputs.If user's operation keys 2 (locking), then he can set up his new place on line by produce message (IT1) at the network place with this key, and deletes previous place on line message.For this reason, he only needs his chip card is inserted in chip card 9 readers 8, and necessary words operation keys 2.
On the chip card, except other specific user data, mainly store personal phonebook's number (PR).When operational lock key 2, personal phonebook's number (PR) is forwarded to exchange (OVSt), offers the directory number decoder and estimates.
Under the situation of outgoing connection, the assignment key among Fig. 6 is used for setting up when access customer is visited in foreign country that to extract call charging from CLR/LST before continuing be important he's user data, and with these data forwarding to call data block.This also finishes by personal phonebook's number PR.Personal phonebook's number PR is stored on the chip card and by the directory number decoder and is used for analyzing, thereby its input also is marked among the CLR/LST.Said method can be set up the user from the random access point of telecommunications network of exchange and is continued, thereby the corresponding input of the call data block by exchange will be called out cost sharing to his account.
User capture exchange OVSt can estimate different character combinations, therefore, receive locking signal 2 and when changing the position the user, start the process that there be input item (presence entries) in foundation/deletion, and when receiving call signal 5, start the process that call data distribute, receiving the memory that dialing information is provided when entering dialing signal 7.
Said method and circuit structure can also be combined in the switching processor of exchange with the system program of respective design.
