0017A embodiment of the present invention will be described below. This embodiment may follow being represented.

0018On Handset has some features that depend on software, which dependent such software Functions more such characteristics as a basic unit. According to the functions the base unit used in combination with the handset to the functions of the handset are limited. The Types of the functions of the base unit and the types of the functions of the Handset are thus reconciled. Furthermore has the handset functions that are independent of the base unit. In this way, a handset together with various Models of basic units are used. Thus, the Cost of the handset will be limited.

0019With In other words, the functions that the handset and the base unit are common, are defined as functions of the handset, and the functions that are independent of the base unit, are used as own Features of the handset set. Thus, a handset used together with a variety of models of the base units will.

0020Under With respect to the <figref idrefs="S24">1</figref> to <figref idrefs="S29">6</figref> is below an embodiment described the invention in detail.

0021Viewed one <figref idrefs="S24">1</figref>So there is a cordless telephone from a base unit <figref>1</figref>That to a telephone line <figref>20</figref> connected is, and at least one handset <figref>2</figref> (The figure in the drawing is not shown). The base unit<figref>1</figref> and the handset <figref>2</figref> can a reciprocal Funkkommunikati on over a certain distance perform (for example, within a distance of 100 to 150 m).

0022The base unit <figref>1</figref> sends and receives from a calling party Audio signals under the control of the control section <figref>3</figref>, The base unit <figref>1</figref> leads the mutual radio communication with the handset <figref>2</figref> by a radio transmitting section and a radio receiving section of a portion <figref>4</figref> for a cordless Communication through. The base unit<figref>1</figref> is a Lauthörtelefonabschnitt <figref>5</figref> and a voice data transfer section (voice messaging section) <figref>6</figref> provided. Thus, by depressing one of the key Lauthörtelefonabschnitts <figref>5</figref> on created state in an off-hook handset that without talking the use of a handset permitted. Moreover, operates when a User is not at home, the voice data transfer section <figref>6</figref>. to record incoming messages. The display section<figref>7</figref> consists a liquid crystal display and the like to a telephone number, the time, different modes of operation and the like display.

0023Viewed one <figref idrefs="S25">2</figref>So leads the handset <figref>2</figref> under the control of the control section <figref>8th</figref> a mutual radio communication with the base unit <figref>1</figref> by a radio transmitting section and a radio receiving section of the section <figref>9</figref> for the cordless Communication through. When a call from the base unit<figref>1</figref> receive is, so is a conversation the conversation section <figref>10</figref> upright receive. In cases where a called party on the call can not respond, here the voice data transfer section <figref>11</figref> operated to the record incoming message. Similarly to the base unit<figref>1</figref> consists the display section <figref>12</figref> a liquid crystal display and the like, a telephone number, the time, different modes and like display.

0024The base unit <figref>1</figref> is further provided with a loading section <figref>13</figref> for loading the handset, by which is mounted to her, provided. As in <figref idrefs="S26">3</figref> is shown, the loading section <figref>13</figref> With charging terminals <figref>30</figref>. <figref>32</figref> and a data connection <figref>34</figref> connected. Dependent on of the models of the base unit <figref>1</figref> , some models the base unit includes a loading section <figref>13</figref> on, the non- to the data terminal <figref>34</figref> but only with charging terminals <figref>30</figref> and <figref>32</figref> provided is. When the handset<figref>2</figref> on the loading section <figref>13</figref> of the base unit <figref>1</figref> is attached, the handset is <figref>2</figref> by the charging terminals <figref>30</figref> and <figref>32</figref> of loading section <figref>13</figref> Loading. At the same time the works Base unit function transfer section <figref>14</figref> of the base unit <figref>1</figref>To automatically data about the functions the base unit <figref>1</figref> belong (Hereinafter simply referred to as "functional data"), by the data port <figref>34</figref> the charging section <figref>13</figref> to the handset <figref>2</figref> transferred to.

0025The Function data thus automatically by the base unit <figref>1</figref> to the handset <figref>2</figref> transfer will be used to allow the handset <figref>2</figref> to permit, the functions of the base unit <figref>1</figref> to identify. To this purpose are fixed function data follows. <ul><li>(1) The data that the functions of the base unit <figref>1</figref> even See, be used.</li><li>(2) As in <figref idrefs="S27">4</figref> is shown, the handset <figref>2</figref> data , which refer to data indicating the models of the base unit <figref>1</figref> and See its features. Here, the data show<figref>40</figref>. <figref>42</figref> and <figref>44</figref> such of "Model A ", the" model B "and the" model C ". The function data of the base unit <figref>1</figref> to the handset <figref>2</figref> be transmitted, denote the data that the model of the base unit <figref>1</figref> specify. In handset <figref>2</figref>That the function data from the base unit <figref>1</figref> receive has a feature operates identification unit <figref>15</figref>. to analyze the function data and identifies the functions, the base unit <figref>1</figref> To belong.</li></ul>

0026meanwhile are some models of the base unit <figref>1</figref> cordless Phone not having a loading section <figref>13</figref> provided. The base unit <figref>1</figref>That no loading portion <figref>13</figref> having, is not with the data connection <figref>34</figref> provided. as previously mentioned was there even among the models of the base unit <figref>1</figref>. which a loading section <figref>13</figref> have, some models not having a data connection <figref>34</figref> are provided. In these cases where the base unit <figref>1</figref> consists of one of the models, which no data connection <figref>34</figref> have, a special Button on the base unit <figref>1</figref> operated to the base unit function transfer section <figref>14</figref> of the base unit <figref>1</figref> to operate as the in <figref idrefs="S24">1</figref> shown is. In this way, the function data of the base unit<figref>1</figref> to the handset <figref>2</figref> by transmit the radio communication.

0027Furthermore , in cases where the base unit <figref>1</figref> not with the base unit function transfer section <figref>14</figref> provided is a dedicated button of the handset <figref>2</figref> actuated to the base unit function transfer section <figref>16</figref> of handset <figref>2</figref> actuate, as in the <figref idrefs="S25">2</figref> is shown. synchronous order operates the function identification unit <figref>15</figref> the handset <figref>2</figref>. the functions of the base unit <figref>1</figref> to identify.

0028Here reads the feature identification unit <figref>15</figref>, As in <figref idrefs="S28">5</figref> shown is a data table showing the functions of the base unit <figref>1</figref> indicating and identifies the features of the base unit <figref>1</figref>, The<figref idrefs="S28">5</figref> shows the differences in the data table according to the models of the base unit <figref>1</figref>, In <figref idrefs="S28">5</figref> are conditions shown in which data with the "Model A", the "Model B" and "Model C" of the base unit <figref>1</figref> connected will be stored. The states of the data <figref>40</figref>. <figref>42</figref> and <figref>44</figref> show those of the "model A ", the" model B "or the" model C ". In the present For specifying the base unit function transfer section "Model A "as the basic unit <figref>1</figref>, Next, read the function identification unit <figref>15</figref> the data table <figref>40</figref> of "Model A ", the hatched is shown. Thereafter, as in the<figref idrefs="S29">6</figref> shown is the Funktionseinstellabschnitt <figref>18</figref> the handset <figref>2</figref> the data Table <figref>40</figref> the base unit <figref>1</figref> with the data table <figref>48</figref> of handset <figref>2</figref> together. The Funktionseinstellabschnitt<figref>18</figref> provides then such functions, which together in the base unit <figref>1</figref> and the handset <figref>2</figref> are present, as the functions of the handset <figref>2</figref> on. <figref idrefs="S29">6</figref> shows, that such features with a continuous line in the data Table <figref>48</figref> the handset <figref>2</figref> are hatched, See the features of the handset <figref>2</figref> together with the base unit <figref>1</figref> may have. In other words, to allow that the base unit <figref>1</figref> and the handset <figref>2</figref> same functions have, are such features of the handset <figref>2</figref>. not covered by the base unit <figref>1</figref> are prepared, blocked. Such a method is used for both functions by software are implemented, as well as for Functions, which Hardware are implemented executed.

0029Such Functions with a dashed line in the data table <figref>19</figref> of handset <figref>2</figref> are hatched, indicate functions, the independent many of the functions performed by the base unit <figref>1</figref> prepared will. Such functions include, for example, setting an area code (area code), setting a language switch for the Display, setting a voice data transfers, adjusting a start time that elapses from a start of voting, before dialing takes place and the same. Although these functions, unrelated to the functions of the base unit <figref>1</figref> are, not by the base unit <figref>1</figref> are before preparing, they can through the handset <figref>2</figref> alone be used. These functions are as independent functions the handset <figref>2</figref> adjusted so that they independently of the models of the base unit <figref>1</figref> can be used. A such an increase the number of functions of the handset <figref>2</figref> is for the user pleasant.

0030Thus provides the Funktionseinstellabschnitt <figref>18</figref> the handset <figref>2</figref> the Features in common by the base unit <figref>1</figref> and the handset <figref>2</figref> be prepared, and at least one the functions specific to the handset <figref>2</figref> belong, as the Functions of the handset <figref>2</figref> on.

0031meanwhile may by Order out of data into a table, such as the data Table <figref>19</figref>, The handset <figref>2</figref> a larger amount store other data in the same ROM. As a result, in cases where a program or functions of the handset <figref>2</figref> and other programs for from the software-dependent Functions in the ROM, which stores a data table stored, are, these programs are expanded. Thus, the handapparatus <figref>2</figref> more have functions. Furthermore can, when the data is stored in the form of the table changes the data easily performed will.

0032The Functions performed by the Funktionseinstellabschnitt <figref>18</figref> of handset <figref>2</figref> be adjusted, are discussed in Detail described .<ul><li>(1) In relation to the base unit <figref>1</figref>. which is adaptable to an information broadcast service of a caller, leads the Funktionseinstellabschnitt <figref>18</figref> an adjustment of the area code by. This means, the handset <figref>2</figref> has a common area code with the base unit <figref>1</figref>, The area code by the base unit <figref>1</figref> is set. Even if the area code is not by the base unit <figref>1</figref> one is provided, it may be set by the handset alone.</li></ul>

0033It Following is a detailed explanation, as the area code is set in the callback function. Here is the phone number that appears in the following explanation is used, represented by numbers and letters.

0034In Japan is, if one assumes that a phone number of a user with "OAB CDE" begins, the area code user "OAB". When a call is received from a local network that has the same area code as the user has, for example, a phone number a caller with all numbers, including area code the caller on the phone as "OAB CDE FGHJ" appears. In addition is, even when a call from an area outside of the Ortsnetzkodes User is received, the caller's phone number with all Numbers that include the area code of the caller, as "OAB CDE FGHJ" appears. In other Words, in Japan, a callback performed with ten digits, and in both cases, either when the call comes from an area that has the same area code comprises, as is present at the user, or when a call from a local network outside the Local network of the user is received.

0035It however, a system that differs from this system in Japan, used in the United States. If it is assumed that the User's telephone number "OAB CDE FGHJ", then the Area code of the user "OAB". The user makes an entry of its Area code "OAB" in the cordless telephone. When a call from a local network that has the same area code as the user has received, the telephone number is the caller usually seven figures as "CDE FGHJ" appears. That is, the area code can be omitted will. Furthermore , a callback are made with these seven digits that are displayed.

0036In the United States depends However, the pattern for performing recall from from local networks. For example, if the telephone number of Caller "OAB CDE FGHJ", then there are four Pattern of the phone number to execute the recall, said these patterns represented as follows: <ul><li>(A) CDE FGHJ</li><li>(B) 1-CDE-FGHJ</li><li>(C) 1-OAB CDE FGHJ</li><li>(D) OAB CDE FGHJ</li></ul>

0037Thus selected according to the circumstances the phone in the local network of the user, the user a fitting Pattern and stores this cordless phone in his.

0038If For example, the user selects the pattern "CDE FGHJ" so the number of digits of the telephone number of the caller is "OAB CDE FGHJ" edited to the to get number "CDE FGHJ", with of the recall accomplished becomes.

0039If a call from a local network outside the area code of the user is received, and the phone number the caller "OAB CDE FGHJ", then is the phone number in the form of eleven digits as "1-OAB CDE FGHJ" displayed, since the area code outside the user's area code is.

0040As has been described above, there are four patterns of the telephone number to recall perform. According to the circumstances the phone in the local network of the user is one of these Mus by ter the user stored in the cordless telephone user.

0041If For example, "1-OAB CDE FGHJ" is selected, so the number of places is edited the phone number of the caller "OAB CDE FGHJ" so that it "1-OAB CDE FGHJ" becomes, the recall performed with this number becomes.

0042The called, if the caller's phone number has the same area code, so the callback is performed with seven digits. Otherwise, if the caller ID of an area code having the outside the user's area code is located, so the call is with eleven digits performed.

0043If the recall using the pattern stored by the user was not successful, namely, when the pattern is not limited to the Conditions in the local network of the user fits, use the handset another Muster to the recall perform again. A pattern to which the callback successfully performed was finally stored.

0044Thus is by storing one of four patterns in the cordless telephone the user, the number of digits of the telephone number of the caller edited automatically when a callback is carried out, and thus, select the telephone number for the local area network is suitable performed.

0045The called, in the case of the Japanese specification is a editing the number the digits of the telephone number is not necessary. On the other hand, in the case of the US specification, the number of digits of the phone number for the recall edited automatically in cordless telephone so that it fits to the local network, and then the call is performed. <ul><li>(2) The Funktionseinstellabschnitt <figref>18</figref> performs setting the switching of the display language by. This setting is necessary in such countries (For example, Canada), where officially a variety of languages is used. The base unit<figref>1</figref> and the handset <figref>2</figref> be for the US-spec previously initialized so that they have a display in English. However, in Canada where English and French are used officially, is if the language on the base unit <figref>1</figref> appropriate should be adjusted so that French appears, the handset <figref>2</figref> the Display according to the setting the base unit <figref>1</figref> on French a. This adjustment of the switching of the display language can by the handset <figref>2</figref> alone regardless of the setting by the base unit <figref>1</figref> be made.</li><li>(3) The Funktionseinstellabschnitt <figref>18</figref> performs setting the voice data transfers through. According to a voice data transfer function, by the base unit <figref>1</figref> is set, the handset <figref>2</figref> together the voice data transfer function with the base unit <figref>1</figref> on. This setting of the voice data transfers can by the handset <figref>2</figref> alone independent of the setting by the base unit <figref>1</figref> be performed.</li><li>(4) The Funktionseinstellabschnitt <figref>18</figref> leads the Setting the Wählbetätigungsstartzeit (Dialing operational tee time) by. This Wählbetätigungsstartzeit is the time by the start of voting elapses before the Select indeed accomplished becomes. The Wählbetätigungsstartzeit varies according to countries. For example is the Wählbetätigungsstartzeit in the United States 1.5 seconds while in Australia 3.5 seconds is. Therefore provides the handset <figref>2</figref> the Wählbetätigungsstartzeit under Wählbetäti transmission start time, in the base unit <figref>1</figref> is adjusted so that the handset <figref>2</figref> same Wählbetätigungsstartzeit as the base unit <figref>1</figref> having. This setting of Wählbetätigungsstartzeit can by the handset <figref>2</figref> alone independent of the setting by the base unit <figref>1</figref> be performed.</li><li>(5) The Funktionseinstellabschnitt <figref>18</figref> performs setting the respective functions of the buttons of the handset <figref>2</figref> by. In other words, the Funktionseinstellabschnitt <figref>18</figref> provides according to the model the base unit <figref>1</figref> the function on each button by he, for example, from a voice message key, a direct station selection key (Direct-station-select key), the for start a conversation , Used under a base and one or more handsets is an override button for the incoming call, a recall key for a telephone directory and the like selects.</li></ul>

0046Especially in case of using a "navigation button" as a cross-arrow key (Cross arrow key), which has a plurality of functions that for the Choose and editing objects on the display section <figref>12</figref> is used, this acts Button for example, as an access key for an incoming call or as a retrieval key the telephone directory, when the handset <figref>2</figref> no wireless Performing communication, but is in its standby position. The button works only as a key to change the volume the Läutetons, When the phone rings with an incoming call.

0047As next is with reference to the flowchart of <figref idrefs="S30">7</figref> a procedure the setting of the functions of the handset of the wireless telephone according to the present Invention.

0048step 1: Either work the basic unit function transfer section <figref>14</figref> of the base unit <figref>1</figref> or the base unit function transfer section <figref>16</figref> of handset <figref>2</figref>,

0049step 2: The function data of the base unit <figref>1</figref> are to the handset <figref>2</figref> transfer.

0050step 3: If the function data transfer were, the function identification unit works <figref>15</figref> of handset <figref>2</figref>,

0051step 4: The operating data of the base unit <figref>1</figref> are analyzed.

0052step 5: The functions of the base unit <figref>1</figref> be identified.

0053step 6: If the functions of the base unit <figref>1</figref> identified are, so the working Funktionseinstellabschnitt <figref>18</figref> of handset <figref>2</figref>,

0054step 7: The functions of the base unit <figref>1</figref> and the functions the handset <figref>2</figref> be collected.

0055step 8: The functions of the handset <figref>2</figref> are the functions the base unit <figref>1</figref> reconciled, and the functions the handset <figref>2</figref>That the independent functions of the handset <figref>2</figref> Include, be set.

0056The Structure of the handset of the cordless phone and the method for the Adjusting its functions have been described in the first place. It is now obvious from the above description that one a recording medium on which recorded the adjusting is, can obtain.

0057As previously described, the handset of the cordless Phone according to the present Invention, some functions that depend on the software, and therefore having the handset in advance more features than the basic unit. The functions of the handset are in accordance with the functions of the base unit, which is used in combination with the handset, limited. The Types of the functions of the base unit and the types of functions of the handset are reconciled. Furthermore has the handset on features that are not from the base unit depend. Thus, a variety of models of the base unit of the cordless Phone be used together with a handset, and thus receives to a flexible use of the handset.

0058Similarly Way allows the method for setting the functions of the Handset of the cordless telephone according to the present invention, that many models of the hand-held unit to use the joint program, and thus obtained flexible use of the handset.

0059Similarly Example, the recording medium that the Funktionseinstellverfahren of the handset of the cordless telephone stores, according to the present Invention in a variety of models of the handset of the cordless be used phone. Thus, the recording medium is a high flexibility and can be conveniently used.
