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, each terminal within the system is assigned a system-unique address, such as a terminal number, and the caller specifies the address assigned to the desired terminal to the system when making a call. searches for the called terminal using this designated address, and realizes communication between the calling terminal and the desired called terminal.

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 needed to input it. Therefore, the operator of the calling terminal should
The address of the desired terminal must be memorized or found from a number book, which is cumbersome.

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, if the name is specified, communication will be made with a terminal located at the closest organizational distance to the calling terminal (for example, within the same department), and communication will be made to a terminal located at a distance farther than this. If you communicate with someone with the same name by specifying the name of the department, the terminal operator will be able to use the address of each terminal to communicate with the person who uses the address on a daily basis and the name of the organization, such as the name of the department, etc. This greatly reduces the complexity when making a call, and reduces the number of operational errors when making a call.

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. do the
Furthermore, when communicating frequently between terminals within the same organization (for example, within a department), the receiving terminal is specified by adding only an easy-to-remember personal name or, in some cases, a simple organization name. We have developed a method for specifying the receiving terminal in a data exchange system that simplifies the operation when making a call, improves operability, and reduces the burden on the operator by making it possible to specify the receiving terminal using a simple method such as The purpose is to provide.

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 ₁ ,
N ₂ and N ₃ constitute one switching network NW with switching equipment,
In addition, T ₁ , T ₂ to _{T 14} are data terminals, and for example, as shown in the figure, terminals T ₁ to _{T 4} are connected to exchange N ₁ ,
T ₅ and T ₆ are connected to exchange N ₂ , terminals T ₇ to _{T 14} are connected to exchange N ₃
It is assumed that the exchanges N ₁ to _{N 3} and each terminal and the exchange are connected by communication lines to constitute one data exchange system, and that this system is installed in one workplace, for example.

FIG. 2 shows an example of how to specify the terminals T ₁ to _{T 14} shown in FIG. 1 by group. The terminals T ₁ to _{T 14} of this data exchange system each belong to a group, in this case, one of the groups G ₁ , G ₂ , and G ₃ . For example, terminals T ₁ to _{T 4} are in group G ₁ , T ₅ and T ₆ are in group G ₂ ,
_T7 to _T14 belong to _G3 . This group (group G ₁ ,
G ₂ , G ₃ ) are further divided into lower-order groups. That is, group G ₁ has two subgroups SG ₁₁ ,
Grouped into SG ₁₂ , terminals T ₁ and T ₂ are subgroups
In SG ₁₁ , terminals T ₃ and T ₄ belong to subgroup SG ₁₂ . Group G ₂ has no subgroups, and terminals T ₅ and T ₆ directly belong to this group G ₂ . Group G ₃ has subgroups SG ₃₁ and SG ₃₂ ;
Furthermore, subgroup SG ₃₁ has lower-order groups, that is, small subgroups SG ₃₁₁ and SG ₃₁₂ , terminals T ₇ and T ₈ are in small subgroup SG ₃₁₁ , and terminals T ₉ to T 8 are in small subgroup SG 311.
T ₁₁ is separated into a small subgroup SG ₃₁₂ and belongs to subgroup SG ₃₁ , terminal T ₁₂ directly belongs to subgroup SG ₃₁ , and terminals T ₁₃ and T ₁₄ belong to subgroup SG ₃₂ . , these terminals T ₇ ~ _{T 14}
is the lower-order small subgroup SG ₃₁₁ , SG ₃₁₂ and subgroup SG ₃₁ and subgroup
Belongs to group _G3 via _SG32 . A group here,
In other words, groups G ₁ , G ₂ , and G ₃ represent business divisions, and lower-order groups, that is, subgroups SG ₁₁ ,
SG ₁₂ , SG ₃₁ , SG ₃₂ , etc. refer to the divisions that are subordinate to each division, and the lower-order groups, i.e., the small subgroups SG ₃₁₁ , SG ₃₁₂ , refer to the divisions that are subordinate to them in each division, and the smaller subgroups SG 311, SG ₃₁₂ , etc. It can be thought of as representing a division, which is a subordinate organization.

Now, the terminals are N(T ₁ ), N(T ₂ )~N(T _i )~
It represents the individual name of the person designated as the operator of T ₁ , T ₂ -T _i -. This name must be unique within the lowest level group (group, subgroup, or minor subgroup), but even if it is the same name in different lowest level groups (groups, subgroups, or minor subgroups). For example, specifying the name N(T ₁ ) and the lowest order group to which the terminal T ₁ belongs, the lowest order group different from the subgroup SG ₁₁ , that is, for example, the terminal T ₉ belonging to the small subgroup SG ₃₁₂ . There is no problem even if the person's name N (T ₉ ) is the same.

If you wish to designate one terminal, for example terminal T ₉ , as the incoming terminal, you can do so from any terminal by using its full name as the address as follows. That is, N(T ₉ )/N(SG ₃₁₂ )/N(SG ₃₁ )/N(G ₃ ) However, N( ) represents the name of the group, subgroup, or small subgroup in parentheses, and / indicates boundaries between named items.

In this way, the terminal is assigned the name of the designated operator [N(T ₉ )], the small subgroup to which it belongs, all names of subgroups and groups [N(SG ₃₁₂ ),
N(SG ₃₁ ), N(G ₃ )], the receiving terminal is uniquely determined within the system, so any calling terminal can specify the receiving terminal without any problem, and the communication between the two parties is Can communicate. 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(T ₉ )/N(SG ₃₁₂ )/N(SG ₃₁ ) (2) N(T ₉ )/N(SG ₃₁₂ ) (3) N(T ₉ ) The above shortened address (1) ), (2), or (3) to specify the desired terminal, the originating terminal T _i
Let the address distance d _ij to the receiving terminal T _j be the terminal T _i ,
It is defined as follows in relation to the group to which T _j belongs.

(a) When terminals T _i and T _j belong to different highest-order groups (corresponding to groups G ₁ , G ₂ , and G ₃ in Figure 2): How to belong terminal T _i to the group There are the following three types within the higher-order group (groups G ₁ , G ₂ , G ₃ ).

(i) When it does not belong to the next group (subgroup).

(ii) When it belongs to the following lower order group (subgroup).

(iii) Belongs to both the next lower group and the next lower group (subgroup and minor subgroup).

In other words, the number S _i (i = the above-mentioned number of stages) indicating how many low-order groups (subgroups, small subgroups) the terminal T _i belongs to within the group.
Define. Here, in the above cases (i), (ii), and (iii), S _i is 0, 1, and 2, respectively. In this case, the address distance d _ij from the originating terminal T _i to the terminating terminal T _j is as follows.

d _ij = S _i +1 ...(1) (b) Terminals T _i and T _j are in the same group (G ₁ in Fig. 2,
G ₂ , G _{3 ,} etc.), and the terminals T _i , T _j
are both lower-order groups (subgroups SG ₁₁ ,
SG ₁₂ , SG ₃₁ , SG ₃₂ , etc., or small subgroups SG ₃₁₁ , SG ₃₁₂ , etc.), the terminal
The address distance between T _i and T _j is: d _ij = S _i − C _ij ……(2) Here, S _i is the number of groups to which terminal T i defined in (a) belongs, and C _ij is the number of groups to which terminal T _i belongs, defined in (a). Indicates the number of low-order groups (subgroups and small subgroups) that commonly include T _i and T _j .

(c) Terminals T _i and T _j are in the same group (the group in Figure 2)
G ₁ , G ₂ , G ₃ ), and all the low-order groups to which terminal T _i belongs are included in the low-order groups to which terminal T _j belongs, then terminal T _i and
The address distance between T _j is: d _ij =S _j −C _ij (3) S _j and C _ij follow the definitions in case (2) above.

In accordance with the above definition, an example of calculating the address distance between two terminals T _i and T _j is shown with respect to FIG.

Example 1: Address distance d _1.5 from terminal T ₁ to terminal T ₅
Since terminals T ₁ and T ₅ belong to groups G ₁ and G ₂ , respectively, that is, they belong to different groups, the definition in (a) above applies, and S ₁ =
1, so from equation (1), d _1.5 = 2.

This means, for example, from terminal T ₁ to terminals other than terminals T ₂ , T ₃ , and T ₄ that belong to the same group G ₁ as terminal T ₁ ,
That is, it is applied to terminals _T5 to _T14 .

Example 2: The address distance d _1.3 from terminal T ₁ to T ₃ is
Since terminals T ₁ and T ₃ belong to the same group G ₁ and both belong to subgroups,
Definition (b) above applies, in which case S ₁ = 1, and terminals T ₁ and T ₃ belong to different subgroups SG ₁₁ and SG ₁₂ , respectively, which commonly contain T ₁ and T ₃ Since the number of subgroups is 0, C _ij =
0, and therefore, from equation (2), d _1.3 =1.

The above example 2 is similarly applied to calculating the address distance from terminal T ₁ to T ₄ , and the address distance d _1.4 from terminal T ₁ to T ₄ is also 1.

Example 3: The address distance d _1.2 from terminal T ₁ to T ₂ is
Since terminals T ₁ and T ₂ belong to the same group G ₁ and also commonly belong to one subgroup SG ₁₁ , S ₁ is 1 and C _1.2 is 1, so the address distance d _1.2 is From equation (2) or equation (3), d _1.2 = 0.

Example 4: Address distance d _12.7 from terminal T ₁₂ to terminal T ₇
The definition (c) above applies, in which case S ₇ =2,
Since C _12.7 = 1 (corresponding to one subgroup SG ₃₁ ), from equation (3), d _12.7 = 1.

FIG. 3 is a diagram showing the basic configuration of exchanges N ₁ , N ₂ , N ₃ , etc. of the data exchange system shown in FIG. 1. In FIG. 3, 101 and 102 are a terminal data reception control unit and a terminal data transmission control unit for terminals T ₁ to _{T o} , respectively, 200 is a call control unit, and 3
01 is an interoffice data transmission control unit to other exchanges, 3
02 is an interoffice data reception control unit from other exchanges. Note that 400 is an address control unit, which has a configuration as described below in order to realize the present invention.

FIG. 4 shows the address control section 4 of the exchange shown in FIG.
An example of the terminal information table provided in 00 is shown.

The table includes, in correspondence with the terminal number, the individual name of the person designated as the operator of the terminal [i.e., N (T _i ) as the terminal name], and the small subgroup name [for example, N (SG ₃₁₁ ) as the section name]. ], subgroup name [for example, N (SG ₁₁ ) as the division name], group name [for example, N (G ₁ ) as the division name], the number of the station where the terminal is accommodated (station number or exchange number), and storage position are recorded, and it is possible to search for each of the above items corresponding to one terminal using any one of the above items.

For example, when requesting communication from terminal T ₁ to terminal T ₃ , the call setup request signal from terminal T ₁ is sent to exchange N ₁
The data is received by the call control unit 200 via the terminal data reception control unit 101 (see FIGS. 1 and 3). Assume that terminal T ₁ specifies terminal T ₃ using an abbreviated address, for example, as shown below. That is, N(T ₃ ) where N(T ₃ ) is the name of the designated operator of terminal T ₃ . A terminal with the same name as N(T ₃ ) also exists in another group G ₃ , that is, in another business division,
For example, suppose that N(T ₃ )=N(T ₇ ).

The call control unit 200 provides the address control unit 400 with accommodation location information LN ₁ of the calling terminal T ₁ and the receiving terminal.
Give the above information of T ₃ and ask to determine which terminal should be connected.

The address control unit 400 searches the table shown in FIG. 4 to find a terminal whose name matches the name of the terminal requested to receive a call. For example, in this case N
Since (T ₃ )=N(T ₇ ), terminal T ₇ is also searched. With this information, the full addresses, host exchanges and host locations of both terminals T ₃ and T ₇ are known.

Here, the address control unit 400 is the originating terminal T ₁
The address distances d _1,3 and d _1,7 between the terminating terminal T ₃ and the originating terminal T ₁ and the terminating terminal T ₇ are calculated. terminal
The address distances d _1,3 and d _1,7 between T ₁ and T ₃ and between T ₁ and T ₇ are determined by the algorithm described in definitions (a), (b), and (c) above [Equation (1), (2), (3)]
We obtain d _1,3 =1 and d _1,7 =2. The terminal with the minimum address distance calculated based on the address N (T ₃ ) of the person's name from the originating terminal T ₁ is determined to be T ₃ , and this determination result and the accommodating exchange information of terminal T ₃ (1, that is, the exchange of N ₁ station) and the accommodation location information LN ₃ are retrieved and passed to the call control unit 200.

Based on this information, the call control unit 200 transfers the calling terminal T 1 to the receiving terminal T ₃ based on the information on the accommodation location LN ₃ of the receiving terminal T ₃ , since the calling terminal and the receiving terminal are accommodated in the same exchange N ₁ in this case. An incoming call signal is transmitted to _T3 via the terminal data transmission control section 102. When the terminal data reception control unit 101 receives an incoming call acceptance signal from the incoming terminal _T4 , the call control unit 2
00, further preparations are made to start communication, and a communicable signal is returned to the originating terminal _T1 . Through the above process, communication between terminals T ₁ and T ₃ 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 20.
0, inter-office data transmission control unit 301 to other exchanges and inter-office data reception control unit 3 of the other station via the line
02 and passed to the call control unit 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 102 receives the incoming call acceptance signal from the called terminal, call control is performed. Part 2
Upon receiving this, 00 prepares to start communication, and transmits the data to the inter-office data transmission control section 301 to the exchange accommodating the originating terminal, and then to the inter-office data reception control section 302 of the exchange accommodating the originating terminal via the line. is transferred to the call control unit 200, where preparations are made to start communication, and then 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, and is independent of the exchange method. Therefore, the present invention can be applied to any of circuit switching, bucket switching, and message switching. It is not necessary to limit the number of addresses for specifying a receiving terminal to one, and the present invention can also be applied when multiple receiving terminals are simultaneously specified using one address to perform broadcast communication.

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 the other party, and this has the effect of making it easier to call the other party's terminal in this type of data exchange system.
