[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wireless terminal device in a wireless communication system that performs communication with a plurality of terminal devices by relaying a base station device.
[0002]
[Prior art]
In the conventional communication system, the identification number indicating the individual number or group number of the terminal device is a form having one identification number for one terminal device, and the numbering system of the identification number is fixed. In addition, the hierarchical structure of identification numbers indicating individual numbers or group numbers of terminal devices and command consoles is fixedly defined by the system and cannot be changed.
[0003]
[Problems to be solved by the invention]
The form having one identification number for one terminal apparatus is different from the form having a plurality of identification numbers such as a group number for one terminal apparatus from a management apparatus connected to the base station apparatus through a communication line. It is possible to change the group number of an arbitrary terminal device or to notify the base station device of the group number changed by the terminal device and update it.
[0004]
On the other hand, in a form having a plurality of identification numbers such as a group number for one terminal device, it is possible to change the group number of an arbitrary terminal device from a management device connected to the base station device through a communication line, Although it is possible to notify the base station device of the group number changed by the device and update it, there is a problem that a message for sending information such as the group number becomes large and connection delay occurs due to communication line congestion. It was difficult to realize.
[0005]
However, in the form of having one identification number for one terminal device, the degree of freedom of calling a plurality of terminal devices in various frames was insufficient. In addition, when a group has a hierarchical structure, it is necessary to change the hierarchical structure according to conditions such as the number of terminal devices and the group configuration in order to meet the demands of systems of various scales. It is necessary to ensure that the same thing is used throughout. In addition, it must be possible to make calls with simple operations.
[0006]
The present invention has been made in order to solve such a conventional problem, and forms an identification number having a high degree of freedom and selectivity in a form having one identification number for one terminal device, and further communication. It is an object of the present invention to provide a wireless terminal device of a wireless communication system in which an input operation of a previous identification number is simple.
[0007]
[Means for Solving the Problems]
A wireless terminal device of a wireless communication system according to the present invention is a wireless terminal device of a wireless communication system that relays a base station device to communicate with a plurality of other wireless terminal devices, and each wireless terminal device includes a plurality of wireless terminal devices. There is one individual identification number consisting of digits, and the identification number consists of a plurality of layers, and the wireless terminal device does not match the number of digits of the highest layer of the input number with the number of digits of the highest layer When the input number is “0” above the input number, 0 suppression is performed to match the number of digits in the highest layer , and then the input number input as the calling number is compared with the identification number of the local station. If the number of digits of the number is less than the number of digits of the identification number of the local station, the number of the upper layer obtained by removing the number of digits of the input number from the lowest digit of the identification number of the local station is Add a new number to the input number It generates a calling number, and performs outgoing call request to the base station apparatus based on the new calling number.
[0008]
With this configuration, it is possible to construct a group configuration with a high degree of freedom in a configuration in which one terminal device holds one identification number, and the operation is simplified even in a system with a large number of units.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0016]
FIG. 1 is a block diagram showing an embodiment of a wireless communication system according to the present invention. The communication system includes a wireless terminal device 1, a wired terminal device 2, and a base station device 3, and the wireless terminal device 1 and the wired terminal device 2 are configured to perform communication by relaying the base station device 3.
[0017]
The wireless terminal device 1 includes an operation device 11, and the operator can input one partner number and perform communication by selecting one or a plurality of communication partners by performing a call operation. The destination number input by the operation device 11 is sent to the transmission number generation means 13 by the input control means 12.
[0018]
The transmission number generation means 13 generates a transmission number from the other party number received from the input control means 12 and the local station identification number and the hierarchy definition information acquired from the storage device 14, and from the radio network controller 16 to the base station apparatus 3. send.
[0019]
When the wireless terminal device 1 receives an incoming call from the base station device 3, the wireless terminal control unit 16 notifies the incoming call determination unit 15 of the incoming call number. The incoming call judging means 15 performs incoming call judgment based on the incoming call number received from the base station apparatus 3 and the own station identification number and the hierarchy definition information acquired from the storage device 14. If the call cannot be received, communication is not entered.
[0020]
The wired terminal device 2 includes an operation device 21, and the operator can perform communication by selecting one or a plurality of communication partners by inputting an arbitrary partner number and performing a call operation. The other party number input by the operating device 21 is sent to the transmission number generation means 23 by the input control means 22 as a transmission number.
[0021]
The transmission number generation means 23 generates a transmission number from the other party number received from the input control means 22 and the local station identification number and hierarchy definition information acquired from the storage device 24, and from the wired line control unit 26 to the base station apparatus 3. send.
[0022]
Further, when the wired terminal device 2 coming from the base station device 3, and notifies the called number to the call judging means 25 from the wireline line control unit 26. Incoming determination unit 25 performs an incoming call determination in the own station identification number and the hierarchical definition information acquired from the called number and the storage device 24 received from the base station apparatus 3, when the own station is incoming friendly enters the communication, the own station If the call cannot be received, communication is not entered.
[0023]
The base station device 3 communicates with the wireless terminal device 1 by the wireless line control unit 31 to accept a call origination request from the wireless terminal device 1 or make an incoming call request to the wireless terminal device 1. Further, the base station device 3 communicates with the wired terminal device 2 by the wired line control unit 33 to accept a call origination request from the wired terminal device 2 or to make an incoming call request to the wired terminal device 2.
[0024]
Further, the base station apparatus 3 holds the call reception request received from the wireless terminal apparatus 1 or the wired terminal apparatus 2 by the call reception number determination means 32 and the identification numbers of all the terminal apparatuses in the system that are acquired from the storage device 35. It is determined from the terminal identification number table and the hierarchy definition information whether the terminal device corresponding to the incoming call number is included in the terminal identification number table. If it is determined that the incoming call number is valid, the incoming call request is summed to the wireless terminal device 1 or the wired terminal device 2 under the control of the communication control means 34, and communication is started.
[0025]
FIG. 2 is a diagram illustrating a number system example of identification numbers of the wireless terminal device 1 and the wired terminal device 2. The wireless terminal device 1 and the wired terminal device 2 hold one identification number as its own station identification number, and the base station device 3 holds the identification numbers of all the terminal devices in the system as a terminal identification number table.
[0026]
In the identification number system shown in FIG. 2, one identification number is expressed by 6-digit numbers, symbols, characters, and the like. The group hierarchy is divided into three hierarchies: two digits (large group hierarchy).
[0027]
The definition of this hierarchy is defined in the system by the hierarchy definition information, and is shared by the base station device 3, the wireless terminal device 1, and the wired terminal device 2 in the same system, thereby giving meaning to the numbers of each hierarchy.
[0028]
FIG. 3 is a diagram illustrating an example of hierarchy definition information that defines a hierarchy of identification numbers. Taking the identification number system shown in FIG. 2 as an example, the uppermost large group hierarchy is 2 digits, the range is 1 to 99, the next middle group hierarchy is 1 digit, and the range is 1 to 9, indicating that the individual number of the next individual layer is 3 digits, the range is 1 to 999, and since the next layer is 0, the numbering system of the identification number is to the higher individual number Indicates that it is a hierarchy. In addition, the total number of digits of each layer indicates that the total number of digits of the identification number is 6.
[0029]
This hierarchy definition information is defined in the system as a hierarchy definition file in which, for example, a numeric ASCII code of each hierarchy and a space code indicating a number are arranged in order, and the same hierarchy definition file is defined as a wireless file in the same system. Based on the hierarchy definition information held in the terminal device 1, the wired terminal device 2, and the base station device 3 and read from the hierarchy definition file, the hierarchy of the identification number can be recognized and the following group system can be established. .
[0030]
FIG. 4 is a diagram illustrating a group configuration example based on identification numbers. In the identification number system shown in FIG. 2, the four terminal devices have identification numbers “011001”, “011005”, “012001”, and “012003”, respectively, and the identification numbers “011001” and “011005” are 4 from the bottom. Since the digits after the same are “011”, they belong to the same middle group “1 ***”. Here, “*” is an unspecified symbol meaning omission.
[0031]
Also, since the identification numbers “012001” and “012003” are the same “0120” in the fourth and subsequent digits, they belong to the same middle group “2 ***”. The identification numbers “011001”, “011005”, “012001”, “012003” belong to the same large group “01 ***” because the fifth digit from the lower order is the same “01”.
[0032]
Although communication between different groups can be performed, terminal devices belonging to the same large group can be connected by inputting a four-digit number by omitting the fifth digit or higher from the lower level of the large group hierarchy. Also, terminal devices belonging to the same middle group can be connected by inputting a three-digit number by omitting the fourth digit or more of the middle group hierarchy.
[0033]
A plurality of terminal devices in the same group can be called together. For example, by inputting a large group number “01 ***” and making a call, all terminal devices having identification numbers “011001”, “011005”, “012001”, and “012003” can be called. By entering the number “011 ***” and making a call, the terminal devices having the identification numbers “011001” and “011005” can be called, and the middle group number “012 ***” is entered and sent. The terminal devices having the identification numbers “012001” and “012003” can be called.
[0034]
Next, the transmission number generation procedure of the wireless communication system in the present embodiment will be described with reference to the processing flowchart shown in FIG. This process is executed in the transmission number generation means 13 and 23 of the wireless terminal device 1 and the wired terminal device 2.
[0035]
First, a variable n indicating a counter of a hierarchy to be determined is initialized (step S1). Next, the number of digits of the input number is determined from the lowest level to the next level (step S2). If it is 3 digits, it is to an individual hierarchy (hierarchy 1), if it is 4 digits, it is to a middle group hierarchy (hierarchy 2), and if it is 6 digits, it is to a large group hierarchy (hierarchy 3).
[0036]
Next, the hierarchy lower than that hierarchy including the number of input digits is set as an input number, and the hierarchy higher than that is used as the transmission number by inputting the number of the same digit of the local station identification number. For example, if the input number is “005” and the local station identification number is “011001”, the transmission number is “011005”.
[0037]
In this case, if the number of input digits does not match the hierarchy, zero suppression is performed to put “0” at the top of the input number to match the number of digits in the hierarchy. For example, if the input number is “05”, this is the number of digits up to the individual level, but since the individual level is 3 digits, it is set to “005” (step S3).
[0038]
The transmission number set in this way is transmitted to the base station apparatus 3 and a transmission request is transmitted (step S4).
[0039]
Next, the incoming number determination procedure of the wireless communication system in the present embodiment will be described with reference to the processing flowchart shown in FIG. This process is executed by the transmission number generation means 13 of the wireless terminal device 1 and the incoming number determination means 15 and 25 of the wired terminal device 2.
[0040]
First, the variable n indicating the counter of the hierarchy to be determined and the variable i determining the number of digits of the unspecified symbol indicating omission in the incoming call number are initialized (step S11). Next, the number of digits of unspecified symbols in the incoming number is counted (step S12).
[0041]
If there is no unspecified symbol in the first digit of the incoming number (step S13), it is determined that there is no unspecified symbol in the incoming number. If there is an unspecified symbol in the incoming call number, it is determined up to which level of the identification number (step S14). For example, if the variable i is 3, it is determined that the individual hierarchy (hierarchy 1) is an unspecified symbol.
[0042]
Next, for the digits below the hierarchy with the unspecified symbol, the number of the same digit of the local station identification number is set instead of the unspecified symbol as the incoming number (step S15). For example, if the incoming number is “011 ***” and the local station identification number is “012001”, it is “011001”.
[0043]
Next, it is determined whether the edited incoming call number or the incoming call number without the unspecified symbol is the same as the local station identification number (step S16). If they are the same, an incoming call response is sent as an incoming call is accepted and a call is entered (step S17). If they are not the same, an incoming call is not accepted and the call is not entered (step S18).
[0044]
Next, the operation of the wireless communication system when a transmission number in which the upper layer of the identification number is omitted is described with reference to the sequence diagram shown in FIG. In the following description, the wireless terminal device 1 will be described as a transmitting station and the wired terminal device 2 will be described as a receiving station, but the reverse is also possible.
[0045]
First, when the wireless terminal device 1 with its own station identification number “011001” inputs the three-digit number “005” from the operation unit 11 (step T1), the wireless terminal device 1 that is the transmitting station terminal inputs the input number “005”. ”Is added with a higher layer number“ 011 ”of its own station identification number by the transmission number generation means 13 to generate a transmission number“ 011005 ”(step T2), and a transmission request is made to the base station apparatus 3 (step S2). T3).
[0046]
The base station device 3 notifies the incoming call request to the wired terminal device 2 that is the called station terminal (step T4). In the receiving station terminal, since the incoming call number “011005” is the same as the local station identification number, the incoming call number determining means 25 determines that the incoming call is possible (step T5) and starts a call (steps T6 to T7).
[0047]
In this way, it is possible to call the receiving terminal between the terminal devices belonging to the same middle group by simply inputting the 3-digit individual layer number among the 6-digit identification numbers.
[0048]
Next, the operation of the wireless communication system when a transmission number in which the lower hierarchy of the identification number is omitted is described with reference to the sequence diagram shown in FIG.
[0049]
First, when a four-digit unspecified number “***” is input from the controller 11 of the wireless terminal device 1 having the local station identification number “011001” (step T11), the wireless terminal device 1 that is the transmitting station terminal inputs the input. The transmission number generation means 13 adds the higher-order number “01” of the local station identification number to the unspecified number “***” generated to generate the transmission number “01 ***” (step T12). Then, a transmission request is made to the base station apparatus 3 (step T13).
[0050]
The base station device 3 notifies the incoming call request to the wired terminal device 2 which is the receiving station terminal (step T14). In the receiving station terminal, since the incoming call number “01 ***” includes the local station identification number “011005”, the incoming call number determination means 25 determines that the incoming call is acceptable (step T15) and starts the call (step T16). ~ T17). In this case, it is determined that the terminal device having the identification numbers “012001” and “012003” is acceptable because it is included in the incoming number “01 ***”.
[0051]
In this way, a plurality of receiving terminals in a large group can be called between terminal devices belonging to the same large group by simply inputting the upper two-digit large group hierarchy number in the six-digit identification number.
[0052]
As described above, in the wireless communication system according to the present embodiment, the identification number indicating the individual number or group number of the terminal device is composed of a plurality of digits and has a plurality of hierarchies. It is possible to make a call that is specified collectively, or to make a call by omitting a higher number in the hierarchy.
[0053]
Further, it is possible to freely change the hierarchical structure of the system by defining information indicating the hierarchical structure by a definition file and changing the definition file, and all terminal devices and base station devices in the system Can have the same hierarchical structure by maintaining a common definition file. This makes it possible to construct a group configuration with a high degree of freedom in a configuration in which one terminal device holds one identification number, which simplifies operation even in a system with a large number of units, and further improves the hierarchical structure. By making it variable, it is possible to easily match the identification number number system even when the system configuration is changed.
[0054]
【The invention's effect】
As described above, according to the present invention, in a communication system in which one terminal device has one identification number, the identification number has a hierarchical structure, and this hierarchical structure has a variable structure to construct a highly flexible group configuration. In addition, it is possible to specify other terminal devices in the same group by omitting the upper layer number and input, and conversely, by specifying only the upper layer number, the terminal of the same layer can be specified. In communication systems where the number of terminals is large and the number of digits of the identification number must be increased, making it possible to call various forms with simple operations, such as specifying a group of devices and calling them together. also, those that can provide a wireless terminal device of a wireless communication system capable of shortening an input number of digits in the calling operation in most cases.
