JPS5842672B2 - Selection signal method - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION In a communication network, when a subscriber selects a partner, the communication purpose is achieved by sending information corresponding to the communication purpose to the network, regardless of the number corresponding to the partner terminal. This relates to selection signaling.

The traditional telecommunications selective signaling system is the communication terminal (telephone,
Using numbers that correspond one-to-one to data communication terminals, etc.
The method used was to specify a specific terminal.

In this case, a subscriber who wishes to receive a call for a specific purpose of communication posts the number in a telephone directory, advertisement, flyer, business card, etc., and the subscriber making the call searches for the number corresponding to the purpose of communication from those publications. This required a procedure.

Conventional communication networks that use such selective signaling systems have the following drawbacks.

(1) Subscribers who wish to receive calls are bothered by the fact that they continue to receive calls even after the purpose of communication has been achieved or even after the purpose of communication has disappeared due to certain circumstances.

For example, if you place an advertisement for ``Private Tutor Wanted,'' even after the caller has achieved his or her goal, you will continue to receive calls from callers who are unaware of the situation.

(1i) Even a calling subscriber with a specific purpose may repeatedly make invalid calls if the other party is no longer able to meet that purpose.

(iii) In order to eliminate the inconvenience for recipients and callers as in (iXii), there is a method to achieve the communication purpose through an intermediary, but in that case, communication costs are high.

B. Can only be disseminated in a limited and narrow range.

C. It takes a long time to achieve the communication objective.

It is difficult to prevent unnecessary calls because the caller discloses his/her number.

There are drawbacks such as.

In order to eliminate these drawbacks, the present invention enables subscribers who wish to receive a call to register their intention to receive a call in a communication network using information corresponding to the purpose when the purpose of receiving a call occurs, and cancels the registration when the purpose disappears. The subscriber inputs information representing the purpose of communication into the communication network, and the network searches for and connects a subscriber that matches the purpose of communication.The drawing will be explained in detail below. .

When the present invention is applied to a general telephone network, it can be used to buy and sell various products (automobiles, real estate, etc.), recruitment, job seeking, exchange of goods, etc. As an example, the structure and operation will be specifically described for buying and selling automobiles. etc. will be explained.

FIG. 1 shows an example of a network configuration, in which the telephone network area is divided into several areas, for example, Area 1 and Area 2, each of which is equipped with a center according to the present invention.

In FIG. 1, A and B. C, D, E, F represent Butschhon, LSl, LS2゜LS3, etc. are local exchanges, TS is a toll exchange, SC1゜SC2 is a centralized service center of this system, and the central service center is a local exchange, a toll exchange. In order to improve the efficiency and speed of information transfer between central service centers and central service centers, signal lines using a common line signaling system are set up between central service centers.

The centralized service center has the function of converting the selection signal according to the invention sent over the common signal line into a conventional telephone number of one communication party suitable for the purpose and transmitting it back to the local exchange.

For communication requests across areas 1 and 2, similar functions are realized by transmitting and receiving selection signals and other signal information from the local exchange between the centralized service centers 5C1 and SC2.

FIG. 2 shows the local exchange LS1. of FIG. It shows the configuration of LS2 and centralized service center SC1.

Local exchange LS1. LS2 consists of an electronic exchange and C
C is a central processing unit that controls the entire exchange.

The MM is a main storage device that stores programs and data, and also serves as a buffer memory.

NW is a switch frame composed of a crossbar switch, etc., TRK is a trunk for telephone calls, and PBORT is a transmission register trunk that receives a selection signal by a push button signal from a telephone set.

5PCE is a communication path control device that controls switch frame NW and communication trunk TR according to instructions from central processing unit CC.
K, controls the operation of the outgoing register trunk PBORT, etc.

DR is a magnetic drum device that is used as an auxiliary storage device.
C8E is a common line signaling device that sends and receives signals to and from other exchanges via the common line signal line.

DCH is a data channel device and magnetic drum device DR1.
Controls data transfer between input/output devices such as the common line signal device C8E and the central processing unit CC and main memory device MM.

In this embodiment, the configuration of the centralized service center is shown for the case where no communication path system equipment is required, and the same equipment as the electronic switching center is used.

Next, the connection operation according to the present invention will be explained.

The subscriber's operation basically consists of three stages.

The first is the operation (registration) of registering with the central service center the use of the selected signaling method according to the present invention, and the second is the operation for communicating with an unspecified party who actually intends to receive a call using this selected signaling method. (communication request), and the third is an operation (cancellation) to cancel registration at the central service center after the purpose of communication is achieved.

Registration is possible at any time.

Once registered, communication requests can be made as many times as desired unless the subscriber requests cancellation due to achievement of the purpose.

At this time, the central service center automatically selects a communication partner at random, so that once communication is performed, there is no need to connect twice to a communication partner whose purpose could not be achieved.

Hereinafter, the registration operation when subscriber B in FIG. 2 wants to sell a car, for example, will be explained.

FIG. 3 is a diagram showing a cathode for a telephone, which corresponds to a telephone directory in this selection signal system.

In FIG. 3, 11 is a page number, for example 3 is shown.

Reference numeral 12 is an item number, for example, the characters ``car'' and the number 199 are shown.

Further, 13 indicates push buttons and functions corresponding to each button.

For example, pushbutton 1 is used to set the vehicle type, pushbutton 2 is used to set the displacement, pushbutton 3 is used to set the model year, pushbutton 4 is used to set the number of kilometers traveled, and pushbutton 7 is used to set the price.

Further, 14 is a column for explaining the selected signal format, etc.

FIG. 4 shows an example of a selection signal format, and FIG. 4 illustrates selection signal formats for each of registration, communication request, and cancellation.

In this example, 199 indicates a car, and nl is 1 for a registration request, 1 for an O1 communication request, and 2 for a cancellation request.

n2 is 0 if you want to sell, 1 if you want to buy, n3
is O when there is a desire to receive a call, and 1 when there is no desire to receive a call.

n4 is 0 when registering an ID, which will be described later, and is 1 when requesting communication by ID.

Further, N is a telephone number of a registered subscriber, and ID means a number (for example, OO to 19) temporarily assigned to a communication partner.

Note that "desiring to receive a call" means an indication that the user wishes to receive a call from an unspecified party after registration.

In addition, the required conditions for answers are displayed as follows.

As mentioned above, #1 indicates the car model, and the next xxx indicates a specific car model name using three digits, for example, 111.

#2 indicates the displacement, and the next △△ indicates the displacement, eg, 1200eC, with two digits, for example o8.

Similarly, #3 indicates the model year, and the next ○○ indicates the specific model year using two digits.

Thereafter, requirements can be registered in the same manner by dialing in accordance with what is defined by the code table attached to the canard of FIG.

Next, a registration operation for registering the above-mentioned requirements will be described.

Subscriber B first dials 199*000*.

Local exchange LS2 uses this as the originating register trunk RBO.
It is received at RT and buffered in the main memory MM.

Local exchange LS2 then sends back an audible signal to subscriber B, prompting subscriber B to send his own telephone number.

In response to this, subscriber B *3□452599*(345
2599 is the telephone number of subscriber B), and the local exchange LS2 sends this again to the calling register trunk RBO.
It is received at RT and buffered in the main memory MM.

After this, the local exchange LS2 analyzes the number 199, learns that it is a connection to the central service center SC1, and transfers 199*OOO* 345259'l to the central service center SC1 via the common signal line. .

As shown in FIG. 5, the centralized service center SC1 reserves one empty selling side subscriber table corresponding to 199 prepared in advance on the main memory device MM for subscriber B, and Write subscriber B's telephone number in the location.

Figure 5 shows an example of the subscriber table on the central service center's memory. Select a group.

22 is a sale/purchase display, in this case n2 in FIG.
Since o('sale) is specified by , the empty block display table 23 is selected by that address.

In the vacancy display table 23, vacancy is 1 and blockage is O.
1 is found, the selling side subscriber table 24 of the address corresponding to it is selected and the telephone number of subscriber B who applied is written in a predetermined position.

If 1 (purchase) is specified by n2 in FIG. is written.

At the same time, a "registration possible" signal is sent back to the local exchange LS2.

Upon receiving this, local exchange LS2 tells subscriber B that it is "registrable".
sends an audible signal.

Subscriber B continues to submit the data representing the desired conditions as shown in FIG.
......Enter in ## format (partial skipping of condition data is also possible).

At this time as well, since there is a limit to the number of digits that can be received by the originating register trunk PBORT, it is necessary to divide the digits into appropriate lengths and repeat the dialing, similar to the above-mentioned dialing.

The local exchange LS2 sends these data again to the centralized service center SC1, and the centralized service center SC1 sets these data in the selling side subscriber table and also sends the telephone number of subscriber B to Chiful, which registers subscribers who wish to sell. Record.

FIG. 6 shows an example of a registration table in the memory of the central service center, where 31 is a special number table B, which is indexed with the number 199, and the sale/purchase display 32 is selected according to the address, and the sale display (0) or purchase display is selected. Select the vehicle type table 33 or 33' according to (1).

The vehicle model table 33 or 33' is indexed by the vehicle model name using, for example, 111, and the displacement table 34 or 34' is selected based on the address.

In the displacement table 34 or 34', the address of the next item is found by indexing, for example, 08, depending on the displacement.

Below, indexing is performed sequentially based on the requirements, and finally, the table 35 for registering subscribers who wish to sell or the registering table 3 for members who wish to purchase
The subscriber's telephone number is recorded in 5/.

Note that N1°N2. N3. ...
......or N1' in Chiful 35',
N2', N3/, . . . each represent a subscriber who wishes to sell or purchase a car that meets the above conditions.

When a series of these registration processes is completed, a "registration complete" signal is transferred from the central service center SC1 to the local exchange LS2 to subscriber B, and the registration process is terminated when subscriber B is disconnected.

If subscriber A wants to purchase an automatic subscriber under the same conditions, use the same operation to enter 199*610*509 etc. 256* and #IX
XX ＃2△△ ＃300 ＃・・・・・・・・・＃
Register using # (5095256 is subscriber A's phone number).

After the above registration is completed, a connection operation will be described when subscriber A actually selects B from among unspecified call recipients and communicates with him.

Subscriber A dials 199*1 according to the dialing format shown in Figure 4.
1*5095256*000* (here, 000 means that when subscriber B is selected in the next step, it is desired to register subscriber B as ID=00.

Note that the ID corresponds to a telephone number temporarily assigned between communicating parties instead of a subscriber number.

), the local exchange LS2 transfers it to the central service center SC□.

The centralized service center SC1 indexes the purchase side subscriber table and finds the table that matches the subscriber number.

The table in Figure 6 is indexed using the purchase conditions in this table, the phone number of one subscriber is randomly picked up from the registration table of subscribers who wish to sell, and the existing communications are listed in the purchase side subscriber table for subscriber A in Figure 5. If the subscriber selected at random this time is included in the subscriber list, the phone number of another subscriber is retrieved from the subscriber registration table for sale and the matching process is performed again. .

Note that the term "already communicated subscriber" here refers to a subscriber with whom communication has already been made, and whose number is recorded in the already communicated subscriber area of the subscriber table.

When subscriber B is selected, if it turns out that B is an uncommunicated subscriber, B's number is written in the ID=00 position of the subscriber number area of the subscriber table, and at the same time,
The telephone number of subscriber B is transmitted from the centralized service center SC1 to the local exchange LS□.

The local exchange LS1 performs a normal exchange connection operation using the transferred number of subscriber B, and establishes a communication path from subscriber A to local exchange L81 to local exchange LS2 to subscriber B.

If subscriber B is busy, the local exchange LS1 notifies the central service center SC1 of this fact, and deletes B from the existing subscribers.

If subscriber A wants to communicate again with a subscriber with whom he has already communicated (for example, if B is that subscriber), please call 19
By dialing 9*11* 5095256*100*,
The existing subscriber number area is searched for ID=OO, the number of B is extracted and transferred to the local exchange LS1, and normal connection operation begins.

Finally, the release operation will be explained.

After subscribers A and B achieve their objectives, subscriber A
Subscriber B dials 99*21* and subscriber B dials 199*20*.

As a result, the centralized service center SC1 erases the contents of the purchasing side and selling side subscriber tables, and displays the vacant status display table as empty.

Also, the corresponding number in the registration table of subscribers who wish to purchase or sell is also deleted.

After these cancellation processes are completed, a "cancellation completion" signal is sent to subscribers A and B, and all records regarding the communication requests of subscribers A and B are erased from the communication network.

An example of the signal transmission/reception sequence for the above registration/communication request/cancellation process is shown in FIGS. 7a to 7d.

FIG. 1a shows an example of a registration processing number transmission/reception sequence, in which NB indicates subscriber B's telephone number.

FIG. 1 shows an example of a communication request processing signal sequence, in which NA indicates the telephone number of subscriber A, and tl indicates the connection delay time.

FIG. 7C is an example of a communication request processing signal sequence, and shows a case where subscriber B is busy.

FIG. 1d is an example of a release processing signal sequence.

Note that the connection delay time t1 when making a communication request is on average 1 second to 2 seconds.
It is possible to suppress it within about seconds.

The selection signaling system according to the invention can also be applied to data switching networks.

In this case, the result is that the switching network side selects one of a large number of unspecified communication partners that meet certain requirements.

Data exchange networks allow the use of high-speed and highly functional terminals, so similar to the telephone network mentioned above, it is possible to buy and sell products, recruit and apply for jobs, etc. in a more comprehensive manner. It is also possible to automatically search for and connect to a game partner of Go, Shogi, etc., through a communication network.

The present invention will be described in detail by taking up a Go service accommodated in a packet switching network as another embodiment of the present invention.

FIG. 8 shows the equipment connection configuration in a packet switching network, where Ps is a packet switching center, and PMX is a packet multiplexing device, which performs terminal line concentration functions and converts character signals received from terminals into packet format, or a switching center. It has the function of inversely converting the packets received from the server into character format.

41 and 41' are four terminals A and B, respectively, which are accommodated in the packet network as start-stop general terminals, and the keyboard 42 is a device used for dialing when making a call and inputting during a game. The display 43 is a display device that corresponds to a base.

The attack 44 is a conversion device that converts the received signal and the input signal from the keyboard 42 (indicating the coordinate position) into figures, and displays the converted signals on the base of the display 43.

Reference numeral 45 denotes a center, which is an information processing device for realizing this selection signaling system not only for the surrounding base but also for other communication requests, and is accommodated in the packet network as a packet-type terminal.

Assume that the subscriber number of the center 45 is 135, and the numbers of the open base terminals A and B are seven-digit numbers NA and NB, respectively.

In a packet-switched network, the operations required by a subscriber basically consist of the three steps of registration, communication request, and cancellation, as in the telephone network, but in this embodiment, registration and communication request can be performed at the same time. method.

At the time of registration/communication request, terminal A is terminal B as shown in Figure 8.
The operation when connected to is explained below.

FIG. 9 is a diagram showing the transmission and reception sequence of packets at the time of registration/communication request. In the figure, CR is a call request, CN is an incoming call, TL is a translation, CA is an incoming call reception, and CC is a Communication is possible, CQ represents a recovery request, CI represents a disconnection instruction, and CF represents a disconnection confirmation.

Further, FIG. 10 is a diagram showing an example of a dial format.

・Fig. 11 shows an example of the memory configuration of the center, where 51 is a service table A, 52 is a gradation table, and 53 is a service table A.
is open base subscriber table 2.54 is open base subscriber table 3
It is.

Further, in the figure, X represents an empty table, Y represents a subscriber busy indication, Z represents a game request, NA represents the subscriber number of the terminal person, and NB represents the subscriber number of terminal B, respectively.

When terminal A makes a call, 135,
IGOlREG, HDAN-2, MDAN-3, REQ
Dial + continuously.

□Receiving this, the packet multiplexer PMX on the terminal A side in FIG. In other words, the registration is related to surrounding groups; 6
The player's rank, the rank of the opponent he or she wishes to play, the fact that he or she wishes to play the game immediately, etc. are set as user information and sent to the packet switching station (PS station).

The PS station that received the CR packet calls the called subscriber number 13.
5 is analyzed, an incoming call bucket) (CN packet) destined for the center is created, and the user information of the CR packet is set and sent.

In accordance with the contents of the CN, the center sequentially indexes from the service file shown in FIG. 11, finds the first address of the open subscriber table, searches using the table empty indication as a key, secures one empty table, and Set various data and finish the registration process.

At this time, since there is a communication request display (REQ) in the user information, the busy display in the subscriber table is set to busy in order to move on to the next communication partner selection process.

In the communication partner selection process, as shown in FIG. 11, the stage head suble is indexed using the desired phase number 3 (MDAN-3), the head address of the four subscriber tables 3 is found, and the subscriber busy display is displayed. Based on the game requesting display, subscriber B is searched and matched.

After setting the busy display of the selected subscriber B to busy, create a translation bucket (TL packet) in which the numbers NA and NB of both subscribers A and B are set as data, and send it to the PS station. do.

The switching connection operation after receiving the TL packet at the PS station is as follows:
The operation is the same as normal connection operation until disconnection.

In other words, at the PS station, an incoming packet (CN packet) from the subscriber number NB of terminal B to terminal B is sent from the TL packet.
is created and sent to the B-side PMX.

Upon receiving this, the PMX sends a paging signal to terminal B, and upon receiving the response signal, creates an incoming call acceptance bucket (CA packet) and sends it to the PS station.

The PS station creates a communicable bucket (CC packet) from the CA packet and sends it to the A-side PMX.

Upon receiving the C/C packet, the A-side PMX sends a communicable signal to terminal A, and thereafter data transmission and reception between terminals A and B, that is, the game begins.

After the game ends, a disconnection request signal from subscriber A is sent to A side PMX.
When the PS station arrives, a recovery request packet (CQ packet) is sent from the PMX to the PS station.

The PS station that received the CQ packet sends a disconnection instruction packet)
(CI packet) is sent to the B-side PMX, and upon receiving this, the PMX sends a disconnection instruction signal to terminal B.

The B-side PMX that has received the disconnection signal from terminal B sends a disconnection confirmation packet (CF packet) to the PS station.

The PS station that received the CF packet sends the same disconnection confirmation bucket (CF packet) to the A-side PMX, and the release of the call is completed.

At this time, the PS station is Ag1. At the same time as the CF packet to IJPMX, the subscriber number N of both terminals A and B is sent to the center.
Communication end bucket with A and NB set as data) (
CE packet).

At the center that received the CE packet, terminal A. The busy display in the subscriber table of B is set to an empty display, and a processing end bucket (PE packet) is sent to the 18 stations, and all disconnection processing is completed.

The above is the connection process when there is a communication request at the same time as registration, but when there is a communication request again, 135 in Figure 10, IG
By dialing in the format of O, REQ+, one communication partner is selected and connected, similar to the communication request processing after the registration processing described above.

When a cancellation request is made by dialing 135, IGO, CCL+ in the format shown in FIG. 10, the cancellation process is executed in almost the same manner as at the time of registration, except that the user information is changed.

In addition to the above example, it is also possible to include the functions of a centralized service center in the exchange program of a local exchange and not provide a centralized service center.

In this case, there is no need for signal transmission and reception between the local exchange and the central service center, so the signal sequence is simplified, but
It is necessary to increase the storage capacity of the external storage device of the local exchange.

This may include, for example, adding more magnetic drums or using magnetic disks.

As explained above, since the selection signal corresponding to the communication purpose is used instead of the conventional selection signal corresponding to the terminal, there is an advantage that communication requests to unspecified parties can be realized quickly, economically and efficiently, and When the purpose disappears, it is possible to immediately notify the communication network that there is no intention to receive a call, so there is an advantage that the subscriber does not have to worry about receiving calls that he or she does not want.
