Description

Service type indication and direct call service connection dialing method in next generation digital wireless telephones.

The present invention relates to a method for displaying a direct call and a dialing method in a next generation digital cordless telephone.

With the development of mobile communication technology, digital wireless telephones have emerged and are used. Second generation cordless telephones (hereinafter referred to as "CT-2") are located within 200 meters of the location of these telepoints via a public base station called a telepoint. Enable the call. CT-2 is the same in terms of handset and private base station compared to conventional cordless phones (CT-0 and CT-1), but it is called telepoint according to cell concept. It can also be used as a public base station, providing superior functionality over existing cordless phones (CT0, CT1). In addition, a digital cordless phone that performs a wireless call function by adding a wireless pager to the CT-2 is referred to as a CT-2 plus.

And the current wireless call system provides a direct call (Meet-Me) service.

1 is a diagram illustrating a direct call display and dialing process in a conventional next generation digital wireless telephone.

In order to use the direct call function currently provided, a direct call service must be subscribed first and his password must be entered and stored in his CT-2.

Referring to the drawings, when a caller calls a number subscribed to a direct call service called 01X-123-4567, the wireless call system receives the voice guidance. Then, the caller receives the voice guidance and selects the direct call service by operating the "key 7" and waits for a predetermined time (about 1 minute and 30 seconds). The paging system then receives this and calls the CT-2 for that number. Then, the CT-2 receives the call signal and notifies the call by alarm or vibration, and displays the call number and service type on the display unit as in " 01X-123-4567 [-] ". At this time, the CT-2 user knows the direct call service through the display data and dials the displayed telephone number by operating the SEND key. Here, the phone number is a call number of CT-2 that subscribes to a direct call service. Then, when a voice guidance message for guiding a direct call service is received from the wireless paging system, the CT-2 transmits it through the speaker. Then, the user listens to the voice prompt message and operates the third key. The CT-2 then transmits the data of the third key to the wireless call system, and the wireless call system sends a voice prompt message to input the password. The user will then hear the voice prompt message and enter a password through the manipulation of the numeric keys. CT-2 then receives it and sends it to the wireless paging system. Then, the wireless call system receives the password and transmits a voice guidance message for inputting the seventh key, and CT-2 receives and sends the voice guidance message. The user will then hear the voice prompt message and operate key 7. CT-2 detects the manipulation of the seventh key and transmits the data of the seventh key to the wireless call system. Then, the wireless call system receives the data of the 7th key and connects a direct call service between the caller and the user of the CT-2.

As described above with reference to FIG. 1, the conventional received call number and service are displayed as "01X-123-4567 [-]". Therefore, it was difficult for the first-time user to know that "[-]" was a direct call service. Therefore, the direct call service could not be made because the CT-2 user did not respond to the direct call service. In addition, as described above, in order to connect to the direct call service, the CT-2 user has to inconvenience a number of key operations.

Accordingly, an object of the present invention is to provide a one-touch dialing method in response to a direct call service in CT-2.

Another object of the present invention is to provide a one-touch, two-touch, manual dialing method by the user's selection in CT-2.

Still another object of the present invention is to provide a method of displaying a service type of a call number received in CT-2.

In order to achieve the above object, the present invention provides a dialing method for joining a direct call service and connecting to a direct call service in a next-generation digital radiotelephone equipped with a wireless pager, wherein the direct call service call signal is inputted. And a second process of performing a direct call service connection by detecting an operation of a one-touch dialing key for direct call service connection after performing the first process.

3 is a flowchart illustrating a password registration process for one-touch dialing in CT-2 plus according to an exemplary embodiment of the present invention.

When the CT-2 Plus is first purchased, both the first password, which is the password of the mobile phone, and the second password, which is the password for the connection of the direct call service, are arbitrarily set as "0". Therefore, when the user purchases CT-2 Plus, the user resets the first password to the desired number. In order to connect to the direct call service through one-touch dialing, the second password must be registered in advance in the CT-2 plus.

Hereinafter, the registration process of the password will be described in detail based on the configuration of FIG. 2.

The user will first operate the menu selection key to select the password registration mode. The menu selection key may be implemented as a function key such as an FCN key. In operation 51, the first controller 10 senses an operation of the menu selection key. In operation 52, the first controller 10 reads the first display data from the first memory and displays the first display data on the display 12. Here, the first display data are selectable menus. The user will then operate the key to select the password registration mode from the menus. Then, in operation 53, when the password registration mode is selected by detecting the key operation, the first controller 10 displays the second display data on the display unit 12 in operation 54. Here, the second display data guides the input of the first password. The user will then manipulate the key corresponding to the first password that reports the second display data. In operation 55, when the first password is input, in operation 55, the first controller 10 displays third display data. The third display data is data for guiding the selection of the direct call service. The user will then operate the selection key to select the direct call service through the third indication data. Thus, when the direct call service is selected in step 57, the first controller 10 displays fourth display data in step 58. The fourth display data is data for guiding input of the second password. The user will then view the fourth display data and manipulate the key corresponding to the second password. Then, in step 59, the first controller 10 displays the fifth display data in step 60 after inputting the second password. The fifth display data is data for guiding the second password to be stored when the second password is correct. So the user will manipulate the storage key if the report is correct. Then, in operation 61, the first controller 10 detects manipulation of the storage key and stores the second password in operation 62.

4A and 4B are flowcharts illustrating a direct call display and dialing process in CT-2 plus according to an embodiment of the present invention.

Hereinafter will be described in detail based on the configuration of FIG.

When the call signal is input, the wireless caller 20 receives the decoded signal and transmits the call number and the service type data to the first controller 10 through the second controller 21. Then, in step 70, if the service type data is a direct call service request signal, the first controller 10 notifies the direct call service request in step 71. The notification of the request for the direct call service is performed by first displaying a call number such as "01X-123-4567 Meet-Me" and display data indicating the type of service. In case of a call, an alarm sounds with a small sound, and while waiting, it informs that a request signal of a direct call service is input through a set alarm or vibration. When a direct call service request signal is input from the wireless caller, when another radio call signal is input immediately after reading, the latest call is first displayed instead of the latest data.

The user will then recognize the direct call service request and manipulate the SEND key, which is the send key. Then, in operation 72, the first controller 10 detects an operation of the SEND key and performs link establishment in operation 73. FIG. Then, if the link is established in step 74, the first control unit 10 transmits the displayed call number and then drives the timer in step 75. Here, the timer may be built in the first control unit 10 and is not shown in FIG. 2.

In operation 76, the first controller 10 checks the timer to determine whether the first predetermined time has come. The first predetermined time is set to 20 seconds because the response time for inputting a guide message for each base station varies from 13 seconds to 20 seconds. Thus, if the determination result of the 76th step is the first predetermined time, the first control unit 10 transmits the data of the third key in step 77. Thereafter, in step 78, the first controller 10 checks the timer and reads out the second password from the first memory when the second predetermined time arrives. Here, the second predetermined time is a time until the next guide message is input in the wireless call system. After that, when the third predetermined time arrives in step 79, the first controller 10 transmits the seventh key data. Here, the third predetermined time is a time until the next guide message is input in the wireless call system. Then, when the data of key 7 is input, the wireless call system forms a call path with the caller who is waiting and the CT-2. Then, when the call path is formed in step 80, the first control unit 10 performs a call mode.

If the communication path is not formed in step 80, the first control unit 10 notifies that an error has occurred in step 93 through display data such as "ERROR" and an alarm, and returns to step 72.

When the first guide message is received when the determination result of the 76th step is not the first predetermined time in step 82, the first controller 10 transmits the first guide message through the speaker 15 in step 83. . Here, the first guide message guides the method of guiding the connection of the direct call service, and in particular, guides the operation of the third key. The user can then listen to the first guide message and select three cases. The first is to wait for the first schedule time, and when the first schedule time arrives, it automatically attempts to connect the direct call service as described above. In the second case, as in step 84, the SEND key is operated again without waiting for the first predetermined time. Then, the first controller 10 proceeds to step 77 and automatically attempts to connect the direct call service without waiting for the first predetermined time. In the third case, a manual operation is performed as in the prior art, and the user may operate the third key according to the first guide message. Then, in step 85, the first controller 10 detects the manipulation of the third key and transmits the third key data. Then, in step 87, the first controller 10 receives the second guide message for guiding the input of the second password and transmits it through the speaker 15. The user will then manipulate the numeric keys to enter the second password accordingly. Then, in operation 88, the first controller 10 inputs the second password and transmits the second password in operation 89. FIG. Then, in step 90, the third guide message for guiding the operation of the seventh key is received and transmitted through the speaker 15. Then, the user will operate the 7th key according to the third guide message. Then, in step 91, the manipulation of the 7th key is sensed, and in step 92, the 7th key data is transmitted and the 80th step is performed.

Although not shown in the drawing, when the flip is closed or the END key, which is an end key, is operated, the first controller 10 stops all operations.

5 is a diagram illustrating a one-touch dialing process in CT-2 plus according to another embodiment of the present invention.

4A and 4B are dialed automatically according to a predetermined time, FIG. 5 dials accordingly when an input of a guide message is detected. 5 shows a subsequent process performed until the direct call service request signal is received and notified.

The user knows that a direct call service request signal is input through display data or an alarm, and then manipulates the SEND key, which is a transmission key, to automatically one-touch dialing. Then, in the first step, the CT-2 establishes a link with the radio calling system, and then transmits the call number to the radio calling system in the second step.

Then, in the third step, the wireless call system receives the call number and sends the first guide message to CT-2. In step 4, the CT-2 detects the input of the first guide message and transmits key 3 data. Then, in step 5, the wireless call system receives the third key data and transmits a second guide message. In step 6, the CT-2 detects the input of the second guide message and transmits the second password. Then, in the seventh step, the wireless call data receives the second password and sends a third guide message. Then, in the eighth step, the CT-2 receives the third guide message and transmits the data of the seventh key. Then, in the ninth step, the wireless call system receives the data of the seventh key and forms a call path between the caller and the CT-2. CT-2 then performs the call mode.

As described above, the present invention displays the service type in letters so that the service type of the called signal can be accurately known and can be connected to the direct call service by one-touch. The user can also attempt to manually connect the direct call service with one-touch and two-touch.
