Description

A method for automatically initiating a call by a terminal

technical field

The invention relates to the technical field of wireless terminal communication, in particular to a method for a terminal to automatically initiate a call.

Background technique

When an ordinary fixed-line telephone terminal using wired technology initiates a call, since the exchange has the function of automatically identifying the number digit by digit, the user only needs to input the number digit by digit. The user performs additional operations. This operation mode is simple, and has become a habit of many users to use the telephone terminal.

For the new fixed-line telephone using wireless technology, the network does not identify the number digit by digit, so its dialing operation method is completely different from that of the traditional wired fixed-line telephone. The operation mode of existing wireless fixed telephone terminal has following two kinds:

1. Adopt the method of additional sending operation. This solution requires the user to firstly input the called number completely, and then perform an additional sending operation, so that the wireless fixed telephone terminal initiates a call. The additional sending operation can be to press a special sending (SEND) key or a key with a similar function, or to press a special key, such as "#" or "*" key to perform a sending operation, or to use a snapshot "differential spring " to perform the send operation.

The disadvantage of the above solution is that its usage method is different from that of traditional wired fixed-line telephone terminals, does not conform to the user's usage habits, and requires additional learning by the user. And, if finish sending operation by adding " SEND key ", then be different with the design of existing landline telephone terminal, must increase hardware, thereby increased hardware cost; If utilize existing " # " or " * " key to carry out If the sending operation is performed, it may conflict with the special service number or the existing additional service; if the sending operation is performed in the way of snapping "bad spring", careless operation may easily lead to disconnection.

2. Use delayed dialing. This solution requires the user to first input the complete called number, and then wait for a relatively long period of time. When there is no new number input within the preset relatively long period of time, the wireless fixed telephone terminal starts to initiate a call.

The disadvantage of the above solution is that there will be a long delay every time a number is dialed, which will increase the call establishment time of the phone and affect the use effect of the user. Moreover, it is difficult to set the waiting time. If it is too long, it will affect the user's use effect; if it is too short, it will easily cause misdialing when the number input by the user is interrupted.

From the above, it can be known that the use of the wireless phone terminal is very inconvenient, requiring the user to re-understand and learn.

Contents of the invention

In view of this, the purpose of the present invention is to provide a method for a terminal to automatically initiate a call. After a user inputs a complete number, the terminal can automatically initiate a call.

In order to achieve the above object, technical solution of the present invention is achieved in that way:

A method for a terminal to automatically initiate a call, the method comprising the following steps:

a. Set the number information record and initialize it;

b. After the user picks up the phone and enters the first number, judge whether the currently input number matches the number in the number information record. If they match, there will be a subsequent number input within the preset time, and the digits of the input number are equal to When the correct number digits are obtained from the category to which it belongs, and when there is no subsequent number input within the preset time, the call connection will be established automatically using the entered number; if it does not match, the preset method will be used , use the currently entered number to establish a call connection.

Preferably, the initialization method described in step a is pre-concentrated writing, or obtained by wireless downloading through the air interface.

Preferably, the number information record in step a is automatically updated in real time according to the call result.

Preferably, said updating number information record further includes the following steps:

c1. Determine whether the call is successful, if yes, execute step b, otherwise execute step c;

c2, judging whether there is a correct matching item of the calling success number in the number information record, if yes, then end, otherwise end after updating the number information record;

c3, judging whether the dialed number is abnormal, if yes, then execute step d, otherwise end;

c4. Determine whether there is a corresponding classification item in the number information record, if yes, update the number information record and end, otherwise end directly.

Preferably, judging whether the call is successful is based on whether the call is started, or whether a ringback tone or a busy tone is received, or whether an error number is returned from the network side.

Preferably, judging whether the dialed-out number is abnormal is based on whether the network side returns an error message or whether the user's operation is wrong.

Preferably, said updating number information records further includes: after judging that the terminal has changed the area of use according to the identification of the network accessed by the terminal, the terminal automatically clears invalid records generated due to the area change.

Preferably, the preset method in step b is to automatically establish a call connection using the currently input number after a delay of a preset time, or to establish a call connection using the currently input number according to the requirements of the voice prompt.

Preferably, in step b, using a pre-set method, applying the currently input number to establish a call connection includes:

Judging whether the user has entered the next number within the preset time, if yes, then repeatedly execute the judgment of whether the currently input number matches the number in the number information record, otherwise use the input number to establish a call connection.

Preferably, the terminal judges whether the input number matches the classification in the local number information record.

Preferably, the terminal is a wireless fixed terminal or a wireless mobile terminal.

By applying the present invention, by matching the inputted numbers, and according to the different matching results, the terminal automatically establishes a connection, so that the user feels that the use method and effect are exactly the same as those of the traditional wired fixed telephone. Moreover, when the region where the terminal is located changes, invalid records can be cleared automatically, so as to adapt to the use of different users. The application of the invention only needs to add functions to the software of the telephone terminal without changing the hardware, has flexible application and is compatible with the existing network.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The idea of the present invention is to store number information records and classify the stored numbers so that each type of number has the same number characteristics or requires the same processing. When the user enters a number, it is judged whether the entered number matches the existing record, if yes, when the number of the wireless fixed telephone terminal is completely entered, the call connection is established immediately, otherwise, the pre-set method is used, and the application The currently entered number establishes a call connection.

The process of number information recording and the process of number matching are described in detail below.

Number information records are the basis of number matching, and each number is recorded in different categories. Each type of number has the same number characteristics, such as the number of digits, or requires the same processing. For each number, part or all of a number can be used to identify the different categories to which the number belongs. The number information record includes the work of the following two parts:

First, the establishment of the initial number information record. The initial correct number information record is obtained through centralized writing in advance, or obtained through wireless downloading through the air interface, or the initial number information record is empty, and the available number information is generated completely through the self-learning of the number information record Record.

Second, the update of the number information record item. The update operation is to automatically add the obtained number information to the number information record, or change or delete invalid items in the number information record, which not only improves the flexibility of use, but also better meets the needs of different users need.

There are many ways to realize the number information record. Here, only the case where the number information record in the wireless fixed telephone terminal is empty is taken as a specific example, and the solution of generating the number information record through self-learning is described in detail.

When the user successfully calls a phone number, if there is no corresponding item in the existing number information record or the corresponding item has an error record, the wireless fixed phone terminal will add or change the classification feature and number digits of the phone number, so as to When the user calls the number again, the correct matching item can be obtained. For the number that fails to call, if it already exists in the number information record, the number will be automatically deleted to eliminate the impact of the wrong record on number matching.

Fig. 1 shows the flow chart of self-learning number information of wireless fixed telephone terminal applying the present invention.

Step 101, after the wireless fixed telephone terminal hangs up, judge whether the call is successful, if yes, execute step 102, otherwise execute step 103;

Step 102, judging whether there is a correct matching item of the successful call number in the number information record, if yes, then directly exit, otherwise execute step 105;

Step 103, judging whether the dialed number is abnormal, such as whether the digits of the number or the number segment are abnormal, if so, then perform step 104, otherwise directly exit;

Step 104, judging whether there is a corresponding classification item in the number information record, if yes, then perform step 105, otherwise directly exit;

Step 105, after updating the number information record, exit directly. The operation of updating the number information record includes the operation of adding, changing or deleting, that is, adding an item that does not exist in the number information record, and changing or deleting an incorrect item in the number information record.

There are many ways to judge the success of the above call, such as taking the start of the call as the sign of the call success, or receiving the ringback tone or busy tone as the sign of the call success, or not receiving the wrong number returned by the network side as the call success There are also many ways to judge the above call failure, such as calling failure if no call is successful, or only when the number returned by the network side is wrong, it is considered call failure; at the same time, there are many ways to judge the outgoing call. Whether the number is abnormal, such as judging whether the dialed number is abnormal through the error message returned by the network side, or judging whether the dialed number is abnormal by detecting the user's operation; moreover, the number information record can be optimized and adjusted, such as merging the same or similar Record items, optimize the order of records, invalidate aged record items, etc.

If the region of use of the wireless fixed telephone terminal changes, the change can be judged by the network identifier accessed by the wireless fixed telephone terminal. After the region of use of the wireless fixed telephone terminal changes, the original invalid records are automatically cleared. For example, if a certain wireless fixed telephone terminal is transferred from region A to region B and continues to be used, the digits of the number in region A are 7 digits, and the digits of the number in region B are 8 digits. When a user in area B dials a number in this area, it is likely that after entering the 7-digit number, the wireless fixed-line terminal is successfully matched and a connection is automatically established, because the matched number is an invalid number in area B. It will definitely fail. Therefore, the number information record in the area A recorded in the number information record of the wireless fixed terminal has become an invalid number, and the invalid number will be automatically deleted.

Through the update operation of the number information record, the new wireless fixed phone terminal can automatically perform dynamic "learning" to adjust and improve the number information record at any time. Moreover, even if the location of the wireless fixed phone terminal changes, the wireless fixed The telephone terminal can also automatically adjust its number information records, and automatically clear out invalid numbers due to region changes. The update operation of the number information record is completed automatically, and does not require additional modification and configuration by the user or the operator.

The principle of number matching is to identify and analyze the input number at the same time when the user enters the number, that is, according to part or all of the number, compare and analyze it with the stored number information record. When the number features match and the number is completely entered, the wireless fixed telephone terminal immediately establishes a call connection. In this way, the effect of the user using the wireless fixed terminal is exactly the same as that of using a traditional wired fixed phone.

There are also many implementation schemes for number matching, here only the method of using number index for matching is taken as a specific embodiment, and the process of number matching is described in detail.

According to the number characteristics of the input number, the wireless fixed telephone terminal searches the local number information record for the category it belongs to, and finds the correct number digits according to the category it belongs to. After detecting that the digits of the number input by the user reach the correct digits, the wireless fixed telephone terminal immediately establishes a call connection. If after the user has input all the numbers, the corresponding matching item is still not found, or the matching item is found but the matching information is wrong, then a preset method is adopted to establish a call connection using the number input by the user. For example, after a preset time delay, the currently input number is used to automatically establish a call connection, or according to the requirements of the voice prompt, the currently input number is used to establish a call connection. The scheme of above-mentioned delayed dialing can be the delayed dialing scheme of the prior art, also can be the delayed dialing scheme of dynamic adjustment, namely reduce the waiting time when the possibility of the user inputting the correct number is large, when the possibility of the user inputting the correct number is small Increase the waiting time, such as setting the delay waiting time between the first and the seventh digit to be longer, and the waiting delay time between the eighth digit and the next digit to be shorter, so that the call connection can be established quickly.

Fig. 2 is a flow chart of number matching using number index in application of the present invention.

Step 201, the user picks up the phone and enters the first number;

Step 202, the wireless fixed telephone terminal judges whether the number entered matches the classification in the number information record, if yes, then execute step 203, otherwise execute step 206;

Step 203, find the correct category of the number input by the user, and obtain the correct number M;

Step 204, judging whether there is a follow-up number input within the preset time, if yes, then execute step 205, otherwise execute step 207;

Step 205, judging whether the input number is equal to the correct number M, if yes, then execute step 207, otherwise return to step 204;

Step 206, judging whether the user has input the next digit within the preset time, if yes, then return to step 202, otherwise execute step 207;

Step 207, use the input number to establish a call connection.

If the user wants to call the host with the number 62283222, and the number information record is classified by the first four digits of the number information as the number characteristics, the processing flow is as follows:

After the user picks up the phone and enters the first number "6", the wireless fixed phone terminal starts to perform matching calculations. It must not obtain the matching number information record item. At this time, the user continues to input the subsequent number "2", and then the wireless fixed phone terminal Use "62" to match the items in the number information record, and it still does not get the matching item. At this time, the user continues to enter the subsequent number, and so on. When the user enters "6228", the wireless fixed telephone terminal The number characteristics in the number information record are classified according to the match, and the digits of this type of number are found to be 8 digits. At this time, the user continues to enter the subsequent number. Call connect.

When performing the matching algorithm, the matching calculation can be performed in all number information records every time, or the next matching calculation can be performed on the basis of the last matching result, so as to narrow the matching range of subsequent numbers and speed up the matching speed ; When searching for number information records, you can use the first field to search, or use other fields or combined fields to search, such as using the third or first four digits to search; for the matched digits, you can use static The matching method can also be a dynamic matching method. For the static matching method, it can be divided into two types: the complete number matching method and the fixed length matching method. If all digits of the number are completely matched, it is The exact matching method, such as only matching the first 6 digits of a number is a fixed-length matching method, such as depending on the type of number, making some numbers only match the first 1 or 2 digits, and making some numbers need to match The top 10 are dynamic matching methods, which can save matching records.

The above-mentioned matching scheme is an embodiment of matching and analyzing the input number and the number information record stored locally through the wireless fixed telephone terminal. It is also possible to make the wireless fixed telephone terminal send the number to the network digit by digit by changing the network protocol. On the network side, the number matching work is completed by the network side, or all successfully called numbers are recorded as legal numbers, when the user enters the number, association matching can be performed, if the matching is successful, the matched number should be used to initiate the call, otherwise the The number entered by the user initiates the call.

The above matching algorithm takes the number as the index item as the premise. Of course, when performing the matching calculation, the length of the input number can also be used as the premise of the index item.

The above only takes the wireless fixed phone terminal as an example, and the method is also applicable to the wireless mobile phone terminal.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
