Description

A method of Activation / Deactivation of Call Function in Idle State on Mobile Station}

The present invention relates to a method of controlling call function activation / deactivation of an idle wireless communication terminal and a computer-readable recording medium recording a program for realizing the method. More particularly, the present invention relates to wireless communication using only a keypad operation of a wireless communication terminal. By deactivating the spontaneous registration function and call request function by "Power Down Registration" in the idle state of the terminal, only the call function is deactivated without turning off the power, and all additional functions other than the call function are normally operated.

In general, a wireless communication terminal refers to a device capable of performing a call while securing mobility of a moving user.

However, the present wireless communication terminal has additional functions similar to PDA (Personal Data Assistance) such as electronic organizer, schedule management, calculator, calendar, clock, contact management, memo, etc. in addition to basic communication functions such as basic voice / video call and data communication. The trend is to add.

As such, as the uses of the wireless communication terminal are diversified, a situation may occur in which the user wants to use only additional functions without using basic communication functions. For example, a student taking a test may use a wireless terminal as a calculator or watch, but never want to receive a call. In addition, the user attending the conference will want the wireless terminal only with additional functions such as clock, memo, contact management, and calendar.

However, the conventional wireless communication terminal is interrupted in terms of the use of the additional function because the incoming signal is given priority when the telephone comes in during the use of the additional function while the power is on. For example, when a wireless communication terminal is inputting a message to send mail among the Internet services provided recently, there is a problem that all incoming messages are deleted when a call is received.

In order to solve the problems described above, a method of preventing a call from being made to a wireless communication terminal which is turned on while in a base station service area and turned on, or a method for rejecting a specific telephone number or for making a call only or incoming call only. A method of artificially creating a state to disable call setup is currently in service.

However, in order to receive such a conventional service, a user has to perform a process of changing a setting by informing a wireless communication service company of a desired service by telephone or mail, or accessing and logging in to a homepage through the Internet.

The present invention has been proposed to solve the problems of the prior art as described above, and a method capable of controlling call function activation / deactivation of an idle wireless communication terminal only by using a keypad and a computer recording a program for realizing the same. The purpose is to provide a recording medium that can be read by.

That is, the exchange function is deactivated by blocking the voluntary registration function and the outgoing call attempt function so that the exchange regards the power of the wireless communication terminal as turned off, and the reverse function activates the call function.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, to explain the method for controlling the call function activation / deactivation of the idle state wireless communication terminal according to the present invention, the types of registrations defined in the CDMA digital wireless communication standard "IS-95A" are enumerated as follows. .

[1] "Power-up registration" means registration performed to notify the exchange when the wireless communication terminal is powered on. That is, the purpose of "power up registration" by "IS-95A" is to inform the exchange that the wireless communication terminal is powered on, so that the exchange informs which cell the terminal is currently located in. When the exchange receives the incoming call request sent to the terminal only when it knows the current location of the terminal, it can call the terminal to connect the call. The wireless communication terminal transmits a registration message including a REG_TYPE field having a value of '0001' through an up channel at a time when T _57m seconds (20 seconds) is idle after the power is turned on, and a base station for the base station Complete the "power up registration" procedure by receiving a registration accepted order.

[2] "Power-down registration" means registration that is made to inform the exchange when the wireless terminal is powered off. That is, the purpose of "power down registration" by "IS-95A" is to inform the exchange that the terminal is powered off, and the exchange that receives this fact connects the call to the terminal when an incoming call request is received. It does not call it because it recognizes that it cannot. When the user requests to turn off the power through the user interface, the terminal transmits a registration message including a "REG_TYPE" field having a value of '0011' through the up channel, and a response message of the base station to the base station is transmitted. Complete the "power down registration" procedure by receiving an Accepted Order.

[3] "Timer-based registration": Registration performed by the wireless terminal at periodic time intervals. If the wireless terminal fails to perform a successful "power-down registration" and the power is turned off, the exchange may change the " Without "Timer-based registration", this is the basis for determining that the power is off.

[4] "Distance-based registration" means registration performed when the wireless communication terminal moves more than a predetermined distance from the last registered cell.

[5] "Zone-based registration": registration performed when a wireless communication terminal enters a new zone.

[6] "Parameter-change registration" means registration performed when parameters owned by a wireless communication terminal are modified. Here, the terminal has its own parameters such as Preferred Slot Cycle Index, Station Class Mark, Band Classes, Power Classes.

[7] "Ordered registration": A registration performed when a base station requests registration by sending a "registration request order" to a wireless communication terminal as needed.

[8] "Implicit registration": registration that a wireless communication terminal sends an "Origination Message" or "Page Response Message" so that the exchange can infer the location of the wireless communication terminal.

[9] "Traffic Channel registration": registration performed by receiving a "Mobile Station Registered Message" in a state in which a wireless communication terminal has been allocated a communication channel, which means that registration has been made in a call state.

On the other hand, the registration of [1] to [6] of the nine registrations is autonomous registration that attempts to determine the registration point of the wireless communication terminal itself, and the registration of [7] to [9] is performed by the exchange wirelessly. In the process of exchanging messages with a communication terminal, the exchange determines whether the terminal is registered.

If the specific wireless communication terminal has performed the "Power Down Registration" state, the exchange determines that the power of the wireless communication terminal is turned off, and thus, until the wireless communication terminal performs a separate registration or calling attempt, In [7] to [9] is not performed. Here, even if the wireless communication terminal performs "Power Down Registration", the terminal in the call function deactivation state according to the present invention will remain in an idle state without being powered off to use the additional function.

However, when the exchange recognizes that the wireless communication terminal is turned off, the incoming call setting is not made. In other words, the call does not come.

Therefore, in order to successfully maintain the communication function deactivation state, the wireless communication terminal must be prevented from attempting the call request by the above voluntary registration and "origination message" defined in "IS-95A" to perform in the idle state. .

Hereinafter, a method of deactivating voluntary registration using the contents of the registration defined in the aforementioned "IS-95A" will be described.

1 is an explanatory diagram showing a system parameter message transmitted by a base station to all wireless communication terminals in a cell according to the conventional "IS-95A" standard.

Among the system parameters shown in FIG. 1, there are “HOME_REG”, “FOR_SID_REG”, “FOR_NID_REG”, “POWER_UP_REG”, “POWER_DOWN_REG”, and “PARAMETER_REG” as parameters that determine whether to activate the spontaneous registration of the wireless communication terminal.

Here, "HOME_REG" (Home Registration Indicator) is a parameter having a function as an indicator indicating whether registration should be performed when the wireless communication terminal is not in a roaming state. Here, "Home" refers to a system to which the wireless communication terminal is subscribed, and the roaming state refers to a state located in a system to which the wireless communication terminal is not subscribed.

Meanwhile, "FOR_SID_REG" (Foreign SID Roamer Registration Indicator) is a parameter having a function as an indicator indicating whether registration should be performed when the wireless communication terminal roams in an SID region different from its SID value. Here, SID (System Identification) refers to a unique identification number of the wireless communication system.

Meanwhile, "FOR_NID_REG" (Foreign NID Roamer Registration Indicator) is a parameter having a function as an indicator indicating whether registration should be performed when the wireless communication terminal roams in an NID region different from its NID value. Here, NID (Network Identification) refers to a unique identification number of a network existing in the wireless communication system.

On the other hand, "PARAMETER_REG" (Parameter-Change Registration Indicator) is a parameter having a function as an indicator indicating whether or not the above-mentioned "Parameter-change registration" should be performed.

On the other hand, the wireless communication terminal stores "REG_ENABLEDs" as a registration status indicator, "REG_ENABLEDs" is "1" if the following three conditions are satisfied, otherwise "0".

[1] When the wireless communication terminal is not roaming and "HOME_REGs" and "MOB_TERM_HOMEp" are 1

[2] When the wireless communication terminal is in NID roaming state and "FOR_NID_REGs" and "MOB_TERM_FOR_NIDp" are 1

[3] When the wireless communication terminal is in SID roaming state and "FOR_SID_REGs" and "MOB_TERM_FOR_SIDp" are 1

On the other hand, if "REG_ENABLEDs" is "1", the wireless communication terminal is activated to perform the above spontaneous registration, and corresponding to [1] to [5] of the above types of registration by artificially deactivating it according to the present invention. You can disable registration. In addition, the registration corresponding to [6] is deactivated when "PARAMETER_REGs" is "0".

In addition, the parameters having the function as the above-mentioned indicator, that is, "HOME_REGs", "FOR_SID_REGs", "FOR_NID_REGs", "PARAMETER_REGs" are "HOME_REG" in the message when the wireless communication terminal receives a new system parameter message from the base station "," FOR_SID_REG "," FOR_NID_REG "," PARAMETER_REG "values are respectively stored in the memory," MOB_TERM_HOMEp "is a parameter having a function as an indicator indicating whether the wireless communication terminal receives an incoming call in" Home " "MOB_TERM_FOR_NIDp" is a parameter having a function as an indicator indicating whether to receive an incoming call in the NID roaming state, and "MOB_TERM_FOR_SIDp" is a parameter having a function as an indicator indicating whether to receive an incoming call in the SID roaming state. to be.

2A and 2B are flowcharts illustrating an embodiment of a call function activation / deactivation control process of a wireless communication terminal according to the present invention.

First, the state indicator "CALL_ENABLEDs" for determining whether to activate or deactivate the call function of the wireless communication terminal is stored in the memory and the default value is set to "1" (200). here,

"CALL_ENABLEDs" is a 1-bit parameter set to store a state of whether to activate or deactivate a call function of a wireless communication terminal according to the present invention. That is, this parameter does not exist in "IS-95".

Thereafter, when the terminal user requests to deactivate the call function using the user interface in the idle state (201), it is determined whether the value of "CALL_ENABLEDs" is "1" (202).

If it is determined that the value of "CALL_ENABLEDs" is "1", the "power down registration" procedure by "IS-95A" is performed (203).

Subsequently, the "HOME_REG", "FOR_SID_REG", "FOR_NID_REG", and "PARAMETER_REG" values of the received system parameter message are stored in a separate memory, and then "HOME_REGs", "FOR_SID_REGs", "FOR_NID_REGs", and "PARAMETER_REGs". The values are all set to '0' (204), and the value of "CALL_ENABLEDs" is set to "0" (205).

On the other hand, if it is determined that the value of "CALL_ENABLEDs" is "0", the call function is considered to be deactivated and thus maintains the original idle state.

On the other hand, when the wireless communication terminal is requested to activate the call function using the user interface in the idle state (206), it is determined whether or not the value of "CALL_ENABLEDs" is "0" (207).

As a result of the determination, when it is determined that the value of "CALL_ENABLEDs" is "0", the values of "HOME_REGs", "FOR_SID_REGs", "FOR_NID_REGs", and "PARAMETER_REGs" are stored in separate memories, "HOME_REG", "FOR_SID_REG", " FOR_NID_REG "and" PARAMETER_REG "values are substituted (208).

Thereafter, a "power up registration" procedure by "IS-95A" is performed (209), and the value of "CALL_ENABLEDs" is set to "1" (210).

On the other hand, if it is determined that the value of "CALL_ENABLEDs" is "1", the call function is considered to be already activated and thus maintains the original idle state.

Subsequently, when the wireless communication terminal receives a new system parameter message from the base station in the idle state (211), it is determined whether the value of "CALL_ENABLEDs" is "0" (212).

If it is determined that the value of "CALL_ENABLEDs" is "0", the "HOME_REG", "FOR_SID_REG", "FOR_NID_REG", and "PARAMETER_REG" values of the received system parameter message are stored in a separate memory (213 ).

Thereafter, "HOME_REGs", "FOR_SID_REGs", "FOR_NID_REGs", and "PARAMETER_REGs" are set to '0' and stored (214).

Subsequently, the processing of the system parameter message received in the idle state is performed as defined in " IS-95A " to complete all procedures (215).

On the other hand, if it is determined that the value of "CALL_ENABLEDs" is "1", processing of the received system parameter message is immediately performed as defined in "IS-95A" to complete all procedures (215).

On the other hand, when the terminal user requests an outgoing call using the user interface in the idle state of the wireless communication terminal (216), it is determined whether the value of "CALL_ENABLEDs" is "0" (217).

As a result of the determination, if it is determined that the value of "CALL_ENABLEDs" is "0", the call request of the user is ignored (218) and the procedure ends.

On the other hand, if it is determined that the value of "CALL_ENABLEDs" is "1", after performing the outgoing call processing procedure as defined in "IS-95A" (219), all processes are completed. Here, the outgoing call processing procedure defined in "IS-95A" means all call processing procedures defined in "IS-95A", for example, a call setup procedure by an originating call, a handoff while moving, and a call. There may be a release procedure.

As a result, the idle wireless communication terminal with "CALL_ENABLEDs" set to "0" can successfully deactivate the call function by deactivating both spontaneous registration and calling function, and if "CALL_ENABLEDs" is set to "1" Is activated to perform the operation according to the "IS-95A" standard.

On the other hand, the call function activation / deactivation control method of the idle state wireless communication terminal according to the present invention has been described as the preferred embodiment "IS-95A" of the CDMA digital cellular wireless communication system, but evolved from "IS-95" Applicability to "IS-95B", "IS-95C", and "IS-2000" has been apparent to those of ordinary skill in the art.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

As described above, the present invention enables the wireless communication terminal user to use only the additional function in a state in which the call function is inactivated, thereby causing a ring tone caused by an incoming call while using the additional function (clock, calculator, memo, text message input, etc.). It is effective in eliminating disturbance caused by vibration, vibration, etc. It is convenient to use the mode switching between call function activation / deactivation only by user's keypad operation. Since it is not exchanged with the base station, there is an effect of increasing the total system capacity by reducing unnecessary load on the system.
