Description

一种用通信终端实现字符输入的方法、装置与系统 A method for implementing a character input by a communication terminal apparatus and systems

技术领域 FIELD

[0001] 本发明涉及通信网络,尤其涉及在通信终端输入字符通过通信网络传送到网络侧设备进行解析和接收的方法、装置与系统。 [0001] The present invention relates to communication networks, and particularly to a communication method for inputting characters in a receiving terminal to parse and transmitted through a communication network to a network-side apparatus, devices and systems.

背景技术 Background technique

[0002] 目前,标准的通信终端,如各种电话终端,包含有以下按键:按键“1”,按键“2”, 按键“3”,按键“4”,按键“5,,,按键“6”,按键“7”,按键“8,,,按键“9”,按键“*”,按键“0,,, [0002] Currently, the standard of communication terminals, such as various telephone terminals, comprising the following keys: the key "1", "2" key, the key "3", the key "4", the key "5 ,,, button" 6 , "key" 7 ", the key" 8 ,,, key "9", keys "*", the key "0 ,,,

按键“#”;共12个按键,为描述方便,称之为标准按键。 Key "#"; a total of 12 keys, for ease of description, referred to a standard key. 不同类型的通信终端可能还添加有其他的功能按键,如静音键、重拨键、暂停键等。 Different types of communication terminals could also add other function keys, such as a mute key, redial key, a pause and so on. 目前通信网络的交互式语音应答(Interactive VoiceResponse, IVR)系统,绝大部分采集用户输入信息的方法是双音多频(Dual ToneMulti-Frequency, DTMF)收号。 Currently interactive voice response communication network (Interactive VoiceResponse, IVR) system, the vast majority of user input information acquisition method is DTMF (Dual ToneMulti-Frequency, DTMF) digit collection. DTMF码是一种用户线信令,用于双音频电话机和交换机侧之间的数据传递。 DTMF code is a subscriber line signaling for data transfer between the switch and the side tone telephone. DTMF收号就是在用户按下标准按键之后,按键信息通过DTMF 编码传到交换机侧,交换机侧通过收号设备解码,从而获得用户的按键信息。 DTMF receiver is standard after the user presses a key, key switch information transmitted via DTMF encoding side, the switch device number received by the decoding side, thereby obtaining the user's key information. 现有技术中的各种通信系统,在需要实时采集用户输入的信息时,如果不局限于使用某一类终端,则只能用到上述标准按键的输入。 Various prior art communication system, when a user needs to input the real-time collection of information, if the terminal is not limited to the use of a certain type, the only input to the used standard keys. 这就给用户输入字符带来了较大的局限,如现有技术中用户不能输入英文字母等。 This brought greater limitations to user input characters, as in prior art user can not enter the letters and so on. 比如,现在技术中的一些IVR系统,有时会要求用户通过通信终端输入个人身份证号码等信息,而部分身份证号码是含有字母的,于是这些IVR系统就只能提示用户用另外一个键(如“*”键)来代替需要输入的字母,这明显造成用户输入信息的不准确,从而影响系统的安全性等一系列问题。 For example, some current art IVR system, sometimes require user input personal identification number or the like via a communication terminal, and the ID number portion containing letters, then the IVR system prompts the user can only use another key (e.g. "*" key) instead of the letters to be entered, which is obviously causing the user to input information is not accurate, thus affecting the security of the system and other issues.

[0017] 本发明实施例提供一种用通信终端实现字符输入的方法,包括: [0017] The method of the present invention provides a character input achieve communication terminal, comprising:

[0018] 顺序接收通信终端发送的双音多频码,根据接收相邻双音多频码的间隔时长与预设间隔时长间的关系,确定出双音多频码组,再根据双音多频码组确定出对应的字符。 [0018] The order receiving communication terminal transmits the DTMF code, based on the received neighbor relation between long DTMF code interval length with a predetermined interval, it is determined that the DTMF code group, and then multiple dual tone determined pilot code group corresponding to the character.

[0019] 具体实施方式 [0019] DETAILED DESCRIPTION

[0020] 在实际应用中,可以预先设定间隔时长阈值,当顺序接收的两个相邻双音多频码的间隔时长大于或等于设定的间隔时长阈值时,将这两个相邻双音多频码划分到不同的双音多频码组,每个双音多频码组唯一对应一个确定的字符。 When [0020] In practical applications, can be pre-set length threshold interval, when the interval of two adjacent dual tone multifrequency code received in sequence length greater than or equal to a length threshold value set interval, the two adjacent bis tone multifrequency code into different DTMF code group, each DTMF code group corresponds to a certain character. 例如:预先建立双音多频码组与字符的对应关系,当确定出一个双音多频码组后,查找存储的对应关系,就可以确定出对应的字符。 For example: DTMF preestablished correspondence relationship and character code group, the latter when it is determined that the DTMF code group, to find the stored correspondence can be determined that the corresponding character.

[0021] 下面分两种情况分别加以说明。 [0021] The following two cases will be described separately.

[0022] 情况一:一个双音多频码组中包含不止一种双音多频码,也即一个字符可以由多个不同的双音多频码来确定。 [0022] Case 1: a DTMF code group contains more than one DTMF code, i.e., a character may be determined by a plurality of different DTMF code.

[0023] 在这种情况下,网络侧在顺序接收通信终端发送的双音多频码后,如果接收相邻双音多频码的间隔时长小于设定的间隔时长阈值(例如间隔时长阈值设为300毫秒),则将顺序接收的双音多频码划分到同一个双音多频码组中,当顺序接收的两个相邻双音多频码的间隔时长大于或等于300毫秒时,将这两个相邻双音多频码划分到不同的双音多频码组,即以这两个相邻的双音多频码为界,结束上一个双音多频码组,开始下一个双音多频码组。 Duration threshold (e.g. length threshold value is set when the interval after [0023] In this case, the network side receives the dual-tone communication terminal transmits multi-frequency code sequence, if the interval DTMF code received adjacent length is less than a set interval 300 ms), then sequentially receives dual tone multifrequency code into the same DTMF code group, when two adjacent 300 ms dual tone received in sequence length greater than or equal to the time interval of the multi-frequency code, the two adjacent DTMF codes into different DTMF code group, i.e., adjacent to the two DTMF code is bounded, on one end of the DTMF code group, beginning at one pair of tone multi-frequency code group.

[0024] 假设网络侧的收号设备启动DTMF收号,以收到“#”键表示结束收号,设收到第一个DTMF码的时间点为0,其收号结果如下表1所示: [0024] the network side is assumed to start digit collection DTMF receiver apparatus to receive the "#" key to indicate the end of digit collection, a first set of DTMF code received time point 0, which collection result in Table 1 below :

[0025] 表1 [0025] TABLE 1

[0026] [0026]

[0027] 若预先设定: [0027] When the preset:

[0028] 收到两个连续的标准按键2、3对应的DTMF码代表输入字母“A” ; [0028] received two consecutive standard DTMF key code representative of the corresponding 2,3 enter the letters "A";

[0029] 收到两个连续的标准按键2、4对应的DTMF码代表输入字母“B” ; [0029] received two consecutive standard DTMF key code representative of the corresponding 2,4 enter the letter "B";

[0030] 收到两个连续的标准按键2、5对应的DTMF码代表输入字母“C” ; [0030] received two consecutive standard DTMF key code representative of the corresponding 2,5 enter the letter "C";

[0031] 收到两个连续的标准按键9、9对应的DTMF码代表输入字母“W” ; [0031] received two consecutive standard DTMF key code representative of the corresponding 9,9 enter the letter "W";

[0032] 假设间隔时长阈值为300毫秒,则上表一解析出的收号结果为:ABC11*W#。 [0032] The threshold 300 milliseconds long interval is assumed, a table is parsed for the collection result: ABC11 * W #.

[0033] 情况二:每一个双音多频码组仅包含一种双音多频码,也即一个字符由同一种双音多频码来确定,连续接收的同一种双音多频码个数不同,代表输入不同的字符。 [0033] Case 2: Each DTMF code group comprises only one DTMF code, i.e., a character of the same DTMF code to determine, with a dual tone multifrequency code continuously received a different numbers represent different input characters.

[0034] 下面以通过现有通信终端(电话终端)的标准按键输入26个英文字母为例,进行详细描述。 [0034] In the following existing communication terminals (telephone terminals) standard 26 key input English letters, for example, be described in detail.

[0035] 参见图1,为本发明实施例提供的一种电话终端具有英文字母输入功能时的键盘布局示意图,即: [0035] Referring to Figure 1, a schematic view of a keyboard layout telephone terminal provided with alphabet input function of the present embodiment of the invention, namely:

[0036] 将英文字母A、B、C分配到电话终端标准按键 '2, ,上;[0037] 将英文字母D、E、F分配到电话终端标准按键' '3, ,上;[0038] 将英文字母G、H、I分配到电话终端标准按键 '4, ,上;[0039] 将英文字母J、K、L分配到电话终端标准按键 '5, ,上;[0040] 将英文字母M、N、0分配到电话终端标准按键 '6, ,上;[0041] 将英文字母P、Q、R、S分配到电话终端标准按键' '7”上[0042] 将英文字母T、U、V分配到电话终端标准按键 '8, ,上;[0043] 将英文字母W、X、Y、Z分配到电话终端标准按键“9”上。 [0036] The letters A, B, C assigned to the telephone terminal standard keys '2, upper; [0037] The letters D, E, F assigned to the telephone terminal standard keys' 3, upper; [0038] the letters G, H, I assigned to the telephone terminal standard keys '4, upper; [0039] the letters J, K, L assigned to the telephone terminal standard key' 5, upper; [0040] the letters M , N, 0 is assigned to the telephone terminal standard key '6, on; [0041] assigned letters P, Q, R, S to the telephone terminal standard key' 7 'on [0042] the letters T, U, V standard keys assigned to the telephone terminal '8, upper; [0043] the letters W, X, Y, Z standard telephone terminals assigned to the key "9."

[0044] 这样,标准按键2可以输入的字符为2、A、B、C ; [0044] Thus, the standard character keys 2 can enter is 2, A, B, C;

[0052 ] 其它标准按键可以输入的字符与现有技术相同。 [0052] Other criteria character input keys is the same as the prior art.

[0053] 在确定了每一个按键可以输入的字符后,由于需要通过一个标准按键输入多个不同字符,还需要确定出输入每一个字符时发送对应标准按键的DTMF码的次数,为此,对分配有字符的每一个标准按键,生成一个通过该标准按键可以输入所分配字符的输入序列; 输入每一个字符时,电话终端重复发送对应标准按键的DTMF码的次数等于该字符在对应输入序列中的位置序号,或者重复发送次数为对应标准按键能输入的字符数量的整数倍再加上该字符在对应输入序列中的位置序号。 [0053] After determining each of the character input keys, the need to enter a different character by a plurality of standard keys, also need to determine the number of times corresponding to the transmission standard DTMF key code is input for each character, for this purpose, for allocated for each standard key character, generates an input sequence can be entered characters are assigned by the standard keys; when each of the input character, the telephone terminal number corresponding to the standard key DTMF code is repeatedly transmitted is equal to the character input in the corresponding sequence the number of characters of the position number, or the number of repeated transmission standard key can correspond to an integral multiple plus input the character input position in the corresponding sequence number.

[0054] 参见图1,数字0-9分别与标准按键0-9 —一对应,分配有英文字母的标准按键2-9,分别生成一个通过该标准按键可以输入对应数字和字母的输入序列,即: [0054] Referring to Figure 1, standard keys 0-9 respectively 0-9 - One correspondence, letters assigned standard keys 2-9, can generate a sequence corresponding to input numbers and letters by the standard keys, which is:

[0055] 标准按键“ 2 ”可以输入的字符序列为“ 2ABC,,; [0055] Standard "2" key to enter a sequence of characters "2ABC ,,;

[0056] 输入数字2时,其在序列中排列第一位,电话终端发送标准按键2对应的DTMF码1次,或者发送该DTMF码的次数N满足N = (4*n+l),其中,n为正整数; [0056] Digital input 2, which are arranged in a first sequence, a standard telephone terminal transmits DTMF code corresponding to the key 2 once, or the number of transmission of DTMF code N satisfies N = (4 * n + l), where , n is a positive integer;

[0057] 输入字母A时,其在序列中排列第二位,电话终端发送标准按键2对应的DTMF码2 次,或者发送该DTMF码的次数N满足N= (4*n+2),其中,n为正整数;且发送该同一DTMF 码的间隔时间不超过预先设定的间隔时长阈值; [0057] When entering the letter A, which are arranged in a second sequence, a standard telephone terminal transmits DTMF code corresponding to the key 2 twice, or the number of transmission of DTMF code N satisfies N = (4 * n + 2), wherein , n is a positive integer; and the time interval to transmit the same DTMF codes does not exceed a threshold interval length set in advance;

[0058] 输入字母B时,其在序列中排列第三位,电话终端发送标准按键2对应的DTMF码3 次,或者发送该DTMF码的次数N满足N= (4*n+3),其中,n为正整数;且发送该同一DTMF 码的间隔时间不超过预先设定的间隔时长阈值; [0058] When entering the letter B, which are arranged in the third sequence, the standard telephone terminal transmits DTMF code corresponding to the key 2 three times, or the number of transmission of DTMF code N satisfies N = (4 * n + 3), wherein , n is a positive integer; and the time interval to transmit the same DTMF codes does not exceed a threshold interval length set in advance;

[0059] 输入字母C时,其在序列中排列第四位,电话终端发送标准按键2对应的DTMF码4 次,或者发送该DTMF码的次数N满足N= (4*n+4),其中,n为正整数;且发送该同一DTMF 码的间隔时间不超过预先设定的间隔时长阈值。 [0059] When entering the letter C, which are arranged in the fourth sequence, a standard telephone terminal transmits DTMF code corresponding to the key 2 four times, or the number of transmission of DTMF code N satisfies N = (4 * n + 4), wherein , n is a positive integer; and the length threshold transmission time interval of the same DTMF code does not exceed a predetermined interval.

[0060] 同理,标准按键“3”可以输入的字符为“3DEF” ; [0060] Similarly, the standard keys "3" characters can be input is "3DEF";

[0061] 标准按键“4”可以输入的字符为“4GHI” [0061] Standard buttons "4" characters can be input is "4GHI"

[0062] 标准按键“ 5 ”可以输入的字符为“ 5JKL” [0062] standard keys "5" characters can be input is "5JKL"

[0063] 标准按键“6”可以输入的字符为“6MN0” [0063] Standard button "6" characters can be input is "6MN0"

[0065] 标准按键“8”可以输入的字符为“8TUV” ; [0065] Standard key "8" characters can be input is "8TUV";

[0066] 标准按键“9”可以输入的字符为“9WXYZ”。 [0066] Standard key "9" characters can be input is "9WXYZ."

[0067] 以用户操作标准按键“2”为例,若连续按N(N彡1)次,且每次间隔时间不超过设定的间隔时长阈值时,则表示输入遵循如下逻辑,即网络侧收号设备根据如下逻辑判断出当前接收的字符: [0067] In normal operation a user key "2" for example, if a continuous press when N (N San 1) times, and each time interval does not exceed the threshold value is set long interval, then follow the following logic input, i.e. the network side No. receiving apparatus determines that the received character according to the following logic:

[0069] 式(1)表示M为N除以4的余数,其中N为统计出的连续收到间隔时间不超过预设的间隔时长阈值的相同DTMF码的个数(用户每操作一次按键“2”,电话终端向网络侧发送一个与标准按键“2”对应的DTMF码,因此,网络侧收到相同DTMF码的个数与用户按下对应标准按键的次数相同)。 Represents [0069] Formula (1) M 4 is N divided by the number of I, where N is the number of the statistics of the same length of DTMF code threshold of the interval time does not exceed a predetermined interval is continuously received (operation every time the user keys " 2 ", a standard telephone terminal transmits to the network side of the key" 2 "corresponding to the DTMF code, therefore, the network side receives the same number of times the user presses the same DTMF codes corresponding to the standard key).

[0070] 如果M等于1,则表示当前输入为数字2 ; [0070] If M is equal to 1, it indicates that the current input is the number 2;

[0071] 如果M等于2,则表示当前输入为字母A ; [0071] If M is equal to 2, then the current input the letter A;

[0072] 如果M等于3,则表示当前输入为字母B ; [0072] If M is equal to 3, then the current input the letter B;

[0073] 如果M等于0,则表示当前输入为字母C。 [0073] If M is equal to 0, then the current input the letter C.

[0074] 同理,当用户操作标准按键“9”时,若连续按N(N彡1)次,且每次间隔时间不超过预先设定的间隔时长阈值,则表示输入遵循如下逻辑,即网络侧收号设备根据如下逻辑判断出当前接收的字符: [0074] Similarly, when the user operates a normal key "9", if the successive N (N = San 1) times, and each time interval of the interval length does not exceed a predetermined threshold value, then follow the following logic input, i.e., receiving a network-side apparatus determines that the number of received character according to the following logic:

[0075] M = N% 5 ; 式(2) [0075] M = N% 5; Formula (2)

[0076] 如果M等于1,则表示当前输入为数字9 ; [0076] If M is equal to 1, it indicates that the current digital input 9;

[0077] 如果M等于2,则表示当前输入字母W; [0077] If M is equal to 2, then the current input the letter W is;

[0078] 如果M等于3,则表示当前输入字母X; [0078] If M is equal to 3, then the current input X-letter;

[0079] 如果M等于4,则表示当前输入字母Y; [0079] If M is equal to 4, the letter represents the Y input current;

[0080] 如果M等于0,则表示当前输入字母Z。 [0080] If M is equal to 0, then the current input the letter Z.

[0081] 其他按键依此类推。 [0081] Other buttons and so on.

[0082] 图1所示键盘布局中,为方便用户操作,已将不同的字母对应分配到不同的标准按键上,由于不同的标准按键有其对应的DTMF码,这样,网络侧还可以根据接收到的不同DTMF码进行双音多频码组的划分;再根据连续接收到的间隔时间不超过预先设定的间隔时长阈值的相同DTMF码的个数,唯一确定出具体接收的字符。 [0082] Figure 1 shows the keyboard layout, for the convenience of user operation, has assigned different letters correspond to different standard keys, since the keys have different standards corresponding DTMF code, so that, according to the network side may also be received DTMF codes to different DTMF code group division; then according to the received continuous time interval does not exceed the number of the same length of DTMF code interval threshold value set in advance, uniquely determines the specific character received.

[0083] 假设预先设置的间隔时长阈值(间隔时长阈值可根据需要进行配置)为300毫秒(ms)。 [0083] The spacer length is assumed that the threshold value set in advance (the threshold interval length can be changed as needed) to 300 milliseconds (ms). 即:网络侧收到相同DTMF码的间隔时间不超过300毫秒时,表示同一个字符的发码, 当顺序接收的相邻的DTMF码划分到同一个双音多频码组中;仅当前后两个DTMF码不相同或两个相同DTMF之间的间隔时长超过300毫秒时,将接收的对应相邻的DTMF码划分到不同的双音双频码组中,表示为接收到不同的字符。 That is: when the network side receives the same interval of DTMF code does not exceed 300 milliseconds, represents the same character code transmitting, when receiving the sequence adjacent DTMF code into the same DTMF code group; this only after two DTMF codes are not identical or the same between the two DTMF interval longer than 300 ms when the received DTMF codes corresponding to adjacent divided into different dual-band dual tone code group indicates a different character is received.

[0084] 假设网络侧的收号设备启动DTMF收号,以收到“#”键表示结束收号,设收到第一个DTMF码的时间点为0,其收号结果如下表2所示: [0084] the network side is assumed to start digit collection DTMF receiver apparatus to receive the "#" key to indicate the end of digit collection, a first set of DTMF code received time point 0, which collection result shown in Table 2 below :

[0085] 表2 [0085] TABLE 2

[0086] [0086]

DTMF 码 2 2 2 2 2 2 1 1 氺 9 9 时间点(ms) 0 200 400 600 800 1000 1200 1400 1600 1800 2200 2400 DTMF code 22222211 Shui 99 time (ms) 0 200 400 600 800 1000 1200 1400 1600 1800 2200 2400

[0087] 则根据上述收号判断逻辑分析为: [0087] According to the number receiving the logical analysis is determined:

[0088] 起始连续收到6个与标准按键“2”对应的DTMF码,且间隔时间均为200毫秒,小于设定的间隔时长阈值300毫秒,因此,判断出接收的字符为“A” ; [0088] received consecutively starting with a standard 6 "2" key corresponding to the DTMF code, and the interval is 200 msec, 300 msec duration threshold is smaller than the set interval, and therefore, it is determined that the received character is "A" ;

8[0089] 第7个和第8个DTMF码为与标准按键“ 1 ”对应的DTMF码,尽管两个DTMF码之间的间隔仅为200毫秒,但由于标准按键“1”上没有定义任何其它字符,因此,判断出接收的字符为连续两个“1”; 8 [0089] The seventh and eighth codes are the standard DTMF key "1" corresponding to the DTMF code, although the spacing between the two DTMF code of only 200 milliseconds, but because the standard key "1" is not defined on any other characters, and therefore, it is determined that the received character as two consecutive "1";

[0090] 第9个DTMF码为与标准按键“*”键对应的DTMF码,因此,判断出接收的字符为 [0090] 9th DTMF code with the standard key "*" DTMF code corresponding to the key, therefore, it is determined that the received character is

"*"; "*";

[0091] 第10个和第11个DTMF码为与标准按键“9”对应的DTMF码,但由于两个DTMF码之间的间隔时间为400毫秒,大于设定的间隔时长阈值300毫秒,因此判断出接收的字符为连续两个“9”; [0091] of 10 and 11 with the standard DTMF code key "9" corresponding to the DTMF code, but since the interval between two DTMF code is 400 milliseconds, the interval length is greater than the set threshold value of 300 milliseconds, it is determined that the received two consecutive characters "9";

[0092] 第12个DTMF码为与标准按键“#”对应的DTMF码,因此,判断出接收的字符为“#”; [0092] 12 of the standard key code DTMF "#" corresponding to the DTMF code, therefore, it is determined that the received character "#";

[0093] 收到字符“#”代表本次收号结束,因此,上表1收号结果为收到字符串: “All*99#”。 [0093] receive the character "#" represents the number of this receiving end, therefore, the results of Table 1 to receive the received number string: "All * 99 #".

[0094] 从图1可以看出,键盘布局中只有标准键和大写英文字母。 [0094] As can be seen from Figure 1, the standard keyboard layout only capital letters and keys. 为了能实现小写英文字母的输入,可以由通信终端向网络侧发送一组约定的DTMF码,以指示后续输入的字符进行了字体切换;当输入的字符为字母时,指示其进行了大小写切换。 In order to enable the input lowercase letters, may be sent by the communication terminal to the network side of a set of conventions DTMF code, indicating the character font inputted subsequent handover; when the character input letter, indicating that it was sensitive switch .

[0095] 例如:在标准按键上添加一个功能键($)来表示进行英文大小写字母之间的切换(默认初始状态为大写)。 [0095] For example: add a function key ($) is represented in the standard key to switch between uppercase and lowercase letters in English (uppercase default initial state). 假设用连续偶数次发送标准按键“*”键对应的DTMF码表示大小写字母之间的切换。 Suppose that continuous even-numbered transmission standard key "*" DTMF code corresponding to the key switch between uppercase and lowercase letters represent. 如图2所示,将切换功能键($)设置在标准按键“*”上。 2, the switching function keys ($) is provided in the "*" key on a standard.

[0096] 假设网络侧收号设备当前收到的DTMF码如下表3所示: [0096] assumed that the network-side apparatus currently received digit collection DTMF code in Table 3 below:

[0097]表 3 [0097] TABLE 3

[0098] [0098]

[0099] 则根据上述收号判断逻辑分析可知,第二次字符收号结果为:“Rt8*w#”。 [0099] According to the number receiving the decision logic analysis, the second character is a collection result: "Rt8 * w #".

[0100] 这样,采用图2所示键盘布局,网络侧的收号字符集为:0_9的数字,*,#,大写英文字母(AZ),小写英文字母(az),以及英文大小写切换控制符(| )。 [0100] Thus, using the keyboard layout shown in FIG., The network side is received No. 2 characters: the number 0_9, *, #, capital letters (AZ), lowercase letters (az), and the English case switching control character (|).

[0101] 上述情况二与情况一的不同之处在于:由于情况二中一个字符仅对应一种TDMF 码,因此,若相邻的两个TDMF码不同,则还可以依据这两个相邻的TDMF码进行双音多频码组的划分,而无需判断这两个相邻的TDMF码之间的接收时间间隔是否大于或等于预设的间隔时长阈值。 [0101] The two cases of a case where the difference is that: since the two cases corresponding to a character code TDMF only one, therefore, when two adjacent codes TDMF different, may also be based on these two adjacent TDMF DTMF code divisional code groups, without determining the reception time between the two adjacent TDMF code interval length is greater than or equal to a preset threshold interval. 由此可见,情况一是一种通用情形,只需设定双音多频码组与字符的对应关系,通过判断接收相邻TDMF码之间的间隔时长进行双音多频码组划分,即可根据确定出的双音多频码组解析出输入的对应字符。 Thus, a general case where one simply set DTMF code group corresponding relation with the character length for DTMF code group division TDMF interval between adjacent symbols received by determining, i.e. may parse the corresponding character input according to the determined DTMF codes. 而情况二实际上是一种具体的应用情形,通过将需要输入的字符预先定义到通信终端的标准按键上,网络侧根据接收到的不同TDMF码、以及连续接收到同一种TDMF码的个数来进行双音多频码组的划分,从而实现解析出输入的对应字符。 The situation is actually a two particular application case, the character to be input by the pre-defined key to a standard communication terminal, the network side according to the received TDMF different codes, and the number of consecutive received symbols of the same TDMF to divide DTMF code groups, enable the parsing of the corresponding character input.

[0102] 需要特别说明的是,上述键盘布局仅为举例,实际应用中,可以将不同的字符(除了英文字母后,还可以另设特殊需要的其它符号等)定义到任意的标准按键上。 [0102] Of particular note, the above is only an example keyboard layout, a practical application, different characters may be (in addition to the letters, other symbols may also be a separate special needs, etc.) to define the arbitrary standard keys. 采用上述同样的原理,由通信终端与网络侧的收号设备预先约定解析规则,即可实现不同字符的输入。 Using the same principle described above, the number of the device receiving a communication terminal and the network side of the pre-agreed parsing rules, can achieve different input characters. [0103] 根据本发明实施例提供的上述字符输入方法,本发明提供一种收号装置实施例, 其结构示意图如图3所示,收号装置11包括双音多频收号模块111和逻辑分析控制模块112。 [0103] According to the above-described character input method according to an embodiment of the present invention, the present invention provides a receiving apparatus No. embodiment, a schematic view of the structure shown in Figure 3, receiving means 11 comprises a number logic 111 and a DTMF number receiving module analysis control module 112. 其中: among them:

[0106] 由于对用户而言,输入字符时的操作相对现有技术只能输入标准按键而言复杂一些,用户可能会不清楚自己当前输入的究竟是什么字符,希望得到确认。 [0106] Since the user, the operation input character relative to the prior art can only enter the standard in terms of key complex, users may not know exactly what their current input characters, hoping to get confirmation. 因此,可以在收号装置11增加一个收号回报模块113,并与逻辑分析控制模块112相连接,在收号回报模块113中预先存储与每一个字符对应的语音信息;当逻辑分析控制模块112判断出每收到一个字符或功能键(而不是DTMF码)之后通知给收号回报模块113,由收号回报模块113用语音通过电信网络传送给通信终端,以便方便用户可以根据语音提示的输入结果决定后续操作。 Thus, it is possible to increase the number receiving means 11 a number receiving return modules 113, and 112 connected to the logic analysis control module previously stored speech information for each character corresponding to the number receiving return module 113; when the logic analysis control module 112 after it is determined that notifies the receipt of each character or function key (instead of DTMF) returns number receiving module 113, a receiving module 113 returns a number to the communication terminal through a voice telecommunications network, so that user can input the voice prompts subsequent operation result of the decision.
