Abstract

PURPOSE:To simplify the call of a remote terminal, by designating an incoming terminal by means of the name, post and name of organization used daily. CONSTITUTION:In requesting a call from a terminal T1 to a terminal T3, a call set request signal from the T1 is received at a call control section 200 via a terminal data reception control section 101. The section 200 gives allocated information of the T1 and the abbreviated address of the T3 to an address control section 400 for the request of the discrimination of the incoming terminal to be connected. The section 400 retrieves a table and searches the terminal named of personnal coincident with the name of personnal of the terminal requested for the incoming call. If the same names exist, the address interval between the outgoing terminal and the incoming terminal is calculated, the minimum interval is selected out, this information, the information of allocated exchange of the T3 and the allocated information are retrieved and given to the section 200. Based on the information, the section 200 transmits an incoming signal to the T3.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for specifying a receiving terminal in a data exchange system, and more specifically, a method for specifying a receiving terminal in a data exchange system. The present invention relates to a method for specifying a receiving terminal in a data exchange system in which the name of an organization such as a department or section can be added and specified.

In conventional data exchange systems, terminals within the system are given system-specific addresses, such as terminal numbers, and
The caller specifies the above address assigned to the desired terminal to the system when making a call, and the system searches for the called terminal using this specified address and connects the calling terminal and the desired called terminal. Communication is realized.

In this conventional method, communication between terminals can be achieved by inputting the address accurately, but the operator of the calling terminal must either memorize the address, usually a number, of the called terminal or look it up from a directory. I had to enter it. Therefore, the operator of the calling terminal has to memorize the address of the desired terminal or find it from a number book, which is complicated.

For example, when a data exchange system is installed exclusively in one company or office, the name of the individual designated as the operator of the terminal is used as the address, and the terminal is designated for communication. When a person is designated as the operator of another terminal, when specifying the name, the communication is made with the terminal that is closest to the calling terminal according to the organization (for example, within the same department). If you communicate with people with the same name at a distance by specifying the name of the department, the terminal operator will be able to use the address of each terminal with the personal name and organization name that they use on a daily basis, such as the name of the department. etc., the complexity of making a call is significantly reduced, and the number of operational errors when making a call is also reduced.

The present invention eliminates the above-mentioned shortcomings in the method of specifying a called terminal in the conventional data exchange system, and allows a calling terminal to specify a called terminal using a person's name and an organization name (for example, the name of a department, section, etc.) that are used on a daily basis. Furthermore, in communications between terminals within the same organization (for example, within a department) that communicate frequently, it is possible to specify the receiving terminal by adding only an easy-to-remember personal name or, in some cases, a simple organization name. By making it possible to specify the receiving terminal using such a simple method, it is possible to simplify the operation when making a call, improve operability, and reduce the burden on the operator when receiving a call in a data exchange system. The purpose is to provide a method for specifying terminals.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a connection configuration diagram of an example of a data exchange system implementing the present invention. In the figure, N, lN2.

N5 is an exchange and constitutes one switching network section, and also has TI
, T2 to T14 are data terminals. For example, as shown in the figure, the terminals T1 to T4 are connected to the exchange N1, and the terminal 'rst T6
are accommodated in the exchange N2, terminals T7 to Tj4 are accommodated in the exchange N, and the exchanges N1 to Ns and each terminal and the exchange are connected by communication lines, forming one data exchange system. Assume that it is installed at a workplace.

FIG. 2 shows an example of how to specify the terminals T1 to T14 shown in FIG. 1 by group. Terminal T of this data exchange system
Each of the 1 to T14 Taihan mothers belongs to one of the groups Gl, G2, and Gs.

For example, terminals T1 to T4 belong to group G1, T5. T4 belongs to G2, and T7 to T+4 belong to G3. This group (groups G1, G2, Gs) is further divided into lower-order groups. That is, group G1 has two subgroups SG1. .

,　　　.

The terminals 'r, , T2 are grouped into subgroup SGH, and the terminals T5 and T4 are grouped into subgroup gG12.
belongs to.

Group G2 has no subgroups and terminals 'rs,
T.

directly belongs to this group G2. Group G3 is
Subgroup SG5. and SG, 2, and the subgroup 5Gsl further has lower order groups, namely the small subgroups SG and SGB+z, and the terminals T7. T8 is separated into a small subgroup F3Gs1+, and terminals T9 to TN are separated into a small subgroup 5G312, forming a subgroup 5Gs1.
Terminal T12 directly belongs to subgroup Sa.
,.

Terminal T13 belonging to K. T14 is subgroup 5
These terminals T7 to T14 belong to group G5 via the low-order small subgroups 5G5N, 5G512, subgroup sas+, and subgroup 5Gs2. Here we have groups, namely groups at, Gz.

G3 subdivides the division into lower-order groups, namely subgroups SGB, 5G12. SGg+, 5Gs2, etc. are subgroups within each division, and lower-order groups, ie, small subgroups 5Gsnz, 5Gs1z, etc. are subgroups SG5. It can be thought of as representing a division, which is an organization further below the division shown in the following.

Now, terminal T1.N(Tl), N(T2)~N(Ti)~. It represents the individual name of the person designated as the operator of T2~Tl~. This name must be unique within the lowest level group (group, subgroup, or minor subgroup), but may be the same name in different lowest level groups (groups, subgroups, or minor subgroups). Without any problem, for example, the name N(Ts) and the name N( There is no problem even if Tj) are the same.

If you wish to designate one terminal, for example terminal T9, as the terminating terminal, you can do so from any terminal by using the full name as the address as follows. That is, N(Tj) / N(5G512) / N(SG
51) /N(Gs) However, N() represents the name of the group, subgroup, or small subgroup in parentheses, and / represents the boundary between the items of the name.

In this way, the terminal can be operated by its designated operator's name (N(T)
t)), all names of small subgroups, subgroups and groups to which they belong (N(SG112) # N(S
G51), N(G5)), then
Since the receiving terminal is uniquely determined within the system, any calling terminal can specify the receiving terminal without any problem, and communication between the two can be carried out. However, in the present invention, in order to simplify the calling operation, it is possible to use subaddresses that omit the designation of the names of groups and lower-order groups, that is, groups, subgroups, and small subgroups. The following subaddresses can be considered.

(1) N(Tt)/N(SGs+z)/N(SGs
+)(2) N(Tt)/N(SGg+2)(3)
N(Tj) The above shortened addresses (1), (2), (
In order to specify a desired terminal using either of 3), the address distance dij from terminal Ti to terminal Tj is set as terminal Ti,
It is defined as follows in relation to the group to which Tj belongs. −
(IL) The highest order group (second
If the terminal Ti belongs to the highest order group (corresponding to groups G1, G2, Gs in the figure) (corresponding to groups G1, G2, Gs):
, Gs), (i) when it does not belong to the next lower order group (subgroup), (i) when it belongs to the next lower order group (subgroup), (i) when it does not belong to the next lower order group (subgroup). When belonging to both a lower order group and a further lower order group (subgroup and small subgroup), there are 03 types. That is, a number 81 (i=the above-mentioned number of stages) indicating how many low-order groups (subgroups, small subgroups) K the terminal Ti belongs to within the group is defined. Here, in the above cases (i), (ii), and (i), Si is 0 and 1.2, respectively. In this case, from terminal Ti to Tj
The address distance dij to is as follows.

d1j=Si+1 ・・・・・・・・・
(1) (b) In the case where terminals Ti and Tj belong to the same group (G1, G2, G, etc. in Fig. 2), both terminals Ti1Tj belong to a lower-order group (

(C) Terminal 1 and Tj are in the same group (group G+ in Figure 2)

When all the low-order groups to which l belongs are included in the low-order groups to which terminal Tj belongs: d1j=Sj-C1j...
(3) Sj and Cij shall follow the definitions in case (2) above.

According to the above definition, for Fig. 2, two terminals Ti
, Tj.

Example 1: Address distance d from terminal T1 to terminal Ts1
1.5, since terminals T1 and Ts belong to groups G1 and G2, respectively, that is, to different group ICs, the above definition (a) is applied, and since S1=l, (1 ), s dl, s = 2.

This is applied, for example, from the terminal T1 to terminals other than the layer terminals T2 eTj and T4 belonging to the same group G1 as the terminal T1, that is, the terminals T5 to T and 4.

Example 2: Address distance d1 from terminal T1 to Ts t
．． 5, since the terminals T1 and T3 belong to the same group G1 and both belong to the subgroup, the above definition (6) is applied, and in this case, s, = l, and
Maku terminals T1 and T4 are in different subgroups 8G
Since the number of subgroups that belong to 11 and 5G12 and that include T1 and T5 in common is 0, C1j=0 and Toshi, therefore, according to equation (2), Sdl, l=1.

The above example 2 is similarly applied to calculating the address distance from terminal T1 to T4, and the address distance d1.4 from terminal T1 to T4 is also 1.

Example 3: Address distance d1.2 from terminal T1 to T2
Since terminals T1 and T2 belong to the same group G1 and also commonly belong to one subgroup 8G, 81 is 1, CI is 1, and 2 is 1. Therefore, the address distance d1.2 is (2) or (3), d1,2 =:
It becomes 0.

Example 4: Address distance d1 from terminal T12 to terminal T7
2.7, the above definition (C) is applied, in this case 87=
2 * C12,7= 1 (Subgroup SGH
1), so according to equation (3), dl2.7''1.

Figure 3 shows switch N of the data exchange system shown in Figure 1.
, , N2, N5, and the like.

In FIG. 3, 101 and 102 are terminals T1 and 102, respectively.
200 is a call control section, 301 is an interoffice data transmission control section to another exchange, and 302 is an interoffice data reception control section for other exchanges. Incidentally, reference numeral 400 denotes an address control section, which has a configuration as described later in order to realize the present invention.

FIG. 4 shows an example of a terminal information key provided in the address control section 400 of the exchange shown in FIG.

The table contains the personal name of the person designated as the operator of the terminal corresponding to the terminal number (i.e., N(T) as the terminal name).
i)), small subgroup name [for example, N( as a section name)
SG River)], subgroup name (for example, N as a department name)
(S011)], group name [for example, N as a division name
(G1)], the number of the station where the terminal is accommodated (station number or exchange number), and the accommodation location are recorded, and one of the above items corresponds to one terminal. It is now possible to search for each of the above items.

For example, when requesting communication from terminal T1 to terminal T5, a call setup request signal from terminal T1 is sent to call control unit 200 via terminal data reception control unit 101 of exchange N1 (see FIGS. 1 and 3). It was received on a semi-cloudy day.

Assume that the terminal T1 specifies the terminal T5 using an abbreviated address, for example, as shown below. That is, N(T3
)/N(SG12) Here, N(Ts) is the name of the designated operator of terminal T51
), N (SG12) is the name of the part where the terminal Ts is installed. Then, a terminal with the same name as N(Ts) is in another group G2. Assume that G3 also exists in another business division, and for example, N(Ts) = N(Ty).

The call control unit 200 passes the accommodating location information LN1 of the originating terminal T1 and the above-mentioned information of the terminating terminal T5 to the address control unit 400, and requests it to determine the terminating terminal to be connected.

The address control unit 400 searches the table shown in FIG.
Search for a terminal whose name matches the name of the terminal requested to receive a call. For example, in this case, since N(Tg) = N(T9), terminal T is also searched. This information determines the address, host exchange, and location of both terminals T5 and T9.

Here, the originating terminal T1, the receiving terminal T3, and the originating terminal T
1 and incoming terminal T3 are terminals T that have the same person's name.
The address distances d1,3 and dl,9 of 9 are calculated.

The address distances d1,5 and dl,9 between terminals T1 and T3 and between terminals T1 and T9 are defined by the above definitions (a), (
The algorithm explained in b) and (e) [formula (
1), (2), (3)), and d
,,s=1 d,,? =2 is obtained. The terminal with the minimum address distance calculated based on the address N (Ts) of the person's name from the calling terminal T1 is determined to be Ts, and this determination result, the accommodation location information of the terminal T3 (1, that is, the exchange of N1), and the accommodation location The information LN5 is retrieved and passed to the call control unit 200K.

Based on this information, the call control unit 200 determines that in this case, since the originating and terminating terminals are accommodated in the same exchange N1,
The transmitting terminal 3 terminal T1 is placed at the accommodation position LN of the receiving terminal T3.

Based on the information, an incoming call signal is transmitted to the terminal T5 via the terminal data transmission control section 10g. When the terminal data reception control section 101 receives an incoming call acceptance signal from the receiving terminal T4, it passes it on to the call control section 200, further prepares to start communication, and returns a communication enable signal to the calling terminal T1. Through the above process, communication between the terminals T1 and Ts becomes possible.

Note that when the originating terminal and the terminating terminal are accommodated in different exchanges, the above-mentioned accommodating location information of the terminating terminal is transmitted from the address control unit 400 to the call control unit 200 to the interoffice data transmission control unit to another exchange. 301 and the line, it is received by the interoffice data reception control section 302 of the other station, and is passed to the call control section 200. Based on this accommodation position information, an incoming call signal is transmitted to the called terminal via the terminal data transmission control unit 102 of the destination exchange, and when the terminal data reception control unit 101 receives the incoming call acceptance signal from the called terminal, call control is performed. In response to this, the unit 200 prepares to start communication, and transmits the data to the exchange that accommodates the originating terminal via the inter-office data transmission control unit 301° line and the inter-office data reception control unit 3 of the exchange that accommodates the originating terminal.
02 and passes it to the call control unit 200, where it also prepares to start communication, and then sends it to the terminal data transmission control unit 10.
1 and returns a communicable signal to the originating terminal. Communication between both terminals is now possible.

In the above, the name of the designated operator of the terminal, the name of the group (division), subgroup (department), and small subgroup (section) can be input from the keyboard of the data terminal device.

The present invention relates to the designation of a receiving terminal in a data exchange system (1) and is independent of the exchange method. Therefore, it can be applied to any switching method such as circuit switching, packet switching, or message switching. It is not necessary to limit the address for specifying the receiving terminal to one;
It can also be applied when performing broadcast communication by specifying a large number of receiving terminals at the same time using one address.

Since the present invention is configured as described above, it is possible to specify a receiving terminal in a data exchange system using the name of a person, affiliation, or organization that is commonly used on a daily basis. There is no need to memorize a dial number or prepare a number book for specifying a destination, and this has the effect that calling a destination terminal in this type of data exchange system is simple and easy.
