Description

The invention relates to a user terminal as defined in claim 1. The invention also relates to a method for responding to a CS type telephone communication. In addition, the invention relates to network switching (or network service or network application server) and calling terminals.
The invention further relates to a computer program for a user terminal.

  In circuit switched (CS) telephone communication, call setup between speakers involves several steps. The call is initiated by the first speaker A dialing the phone number of the second speaker B's B terminal at his A terminal. The telephone communication network routes the call to the B terminal using the dialed telephone number information. Next, the call is notified to the speaker B by a signal generated at the B terminal. Then, the speaker B can answer the call by operating the B terminal. The B terminal notifies the network that the call has been accepted. After answering by the B terminal, the call is connected between the A terminal and the B terminal, and voice communication between the speaker A and the speaker B is established.

  This call setup is implemented in both wired and mobile networks. Both the A terminal and the B terminal may be wired telephones or mobile telephones.

  The specifications for mobile CS telephony are known (GSM TS 04.07 version 7.3.0, chapter 6.2), which describes the sequence of states of a finite state machine of a telephone during call setup, ongoing and disconnected. ing. FIG. 1 shows a part of a CS call state diagram 1 in the prior art. The finite state machine of the telephone (terminal B) can be in several different states. Normally, when the telephone is idle and not communicating, the telephone state is "Null" state 10.

  A call request by terminal A can be received as an incoming signal from the network. This signal causes the finite state machine to move its state to the “call receiving” state 20. The finite state machine reaches the “call receiving” state 20 through several intermediate states 15. In this state, the user of terminal B (speaker B) receives an incoming call notification. When the user issues a response, for example, by pressing the “acknowledge” key on the B terminal keypad, the finite state machine communicates voice between the A terminal speaker A and the B terminal speaker B. Changes to an executable active state 30. The user's response to an incoming call is schematically illustrated by a block A1 connected to the “call reception state” 20 by a dotted arrow.

  The finite state machine reaches the “active” state 30 through the intermediate state 25. At the same time, a CS call response signal is returned to the exchange to establish a voice communication phase. When the call is disconnected, the finite state machine changes to the “free” state 10, possibly through some other intermediate state 35. At this time, the exchange is notified of the call disconnection.

  In the prior art, speaker B is required to activate terminal B by executing an operation on terminal B (eg, pressing a “response” button).

  The method described above for answering an incoming call disadvantageously limits the usability and functionality of the telephone. That is, the prior art methods can limit user-directed services.

  An object of the present invention is to provide a terminal having an improved response function with respect to the prior art.

  To achieve this object, the present invention comprises at least a CS telephone device for processing CS telephone signals received and transmitted on a circuit switched bearer service, and a user terminal for communicating on a telecommunication network And configured to receive an additional response related signal associated with an incoming incoming CS alert signal and in response to information contained in (or derived from) the additional response related signal; A user terminal configured to transmit a response signal or a CS response signal on a circuit switched bearer service is provided.

  Advantageously, the present invention provides the possibility of an automatic answer that does not require user operation for an incoming call at the user terminal.

  The present invention also provides at least one circuit-switched bearer service for receiving and transmitting CS-type telephone signals, wherein the circuit-switched bearer is configured to transmit an incoming call CS alarm signal to a user terminal. A network service in a telecommunications network comprising a service, the additional response associated with an incoming CS alert signal and configured to cause a user terminal to provide a response signal or CS response signal on a circuit switched bearer service The present invention relates to a network service configured to transmit a related signal to a user terminal.

  Furthermore, the present invention comprises at least one CS telephone device for processing CS type telephone signals received and transmitted on a circuit switched bearer service, and a calling terminal or A for communicating on a telecommunication network An additional response related signal having information on an outgoing call, which is associated with a CS call setup signal transmitted for an outgoing call by a user terminal, and is a response signal or a CS response to the user terminal receiving the call The present invention relates to a calling terminal or an A terminal configured to transmit an additional response related signal that causes a signal to be provided on a circuit switched bearer service.

Furthermore, the present invention is a method for communicating over a telecommunications network comprising:
-Processing a CS telephone signal received and transmitted on a circuit switched bearer service; receiving an additional response related signal associated with an incoming incoming CS alarm signal;
Transmitting a response signal or a CS response signal over a circuit switched bearer service in response to information contained in or obtained from the additional response related signal.

-Receive additional response related signals associated with incoming CS alert signals for incoming calls;
-A function of transmitting a response signal or a CS response signal on a circuit-switched bearer service in response to information included in or obtained from an additional response related signal.

  FIG. 2 is a diagram schematically showing a response procedure in the conventional terminal 2.

  The terminal 2 is generally a mobile phone, but may be a wired phone. The terminal 2 is configured to communicate on the telecommunications network 3.

  The terminal 2 as an electronic device includes a CS telephone device CS0 configured to process a CS type telephone signal. The CS type telephone signal can be realized using, for example, a DTAP (Direct Transfer Application Part) protocol as used in GSM (Global System for Mobile communications). Furthermore, the terminal 2 provides a graphical user interface (GUI) and can be configured to provide execution of one or more applications that can be implemented locally and possibly (but not necessarily) within the GUI. An additional device D0 can be provided. The additional device D0 typically includes a memory for storing data and / or multiple applications.

  The CS telephone apparatus CS0 includes a finite state machine FSM that can manage CS telephone functions.

  The response procedure shown for terminal 2 is consistent with the CS call state diagram of FIG.

  A CS alarm signal CS1 for notifying a call request for an incoming call is given from the network 3 to the terminal 2. As described above with respect to FIG. 1, the finite state machine FSM provides an incoming call notification to the user of the terminal 2.

  The user responds by an operation of pressing a “response” button, for example, as shown here as the operation signal A1.

  A signal A1 by the user operation is given to the finite state machine FSM. The finite state machine FSM prepares for voice communication in the “active” state 30 with an acceptance signal A2. At this time, a CS type response signal CS2 is transmitted to the network 3 to notify that the call has been answered, and voice communication 7 with the calling terminal or the A terminal (not shown) is started.

  FIG. 3 is a diagram showing a user terminal 5 according to the present invention.

  In FIG. 3, configurations having the same reference numerals as those in the previous drawings indicate the same configurations.

  In the present invention, when the additional packet switched signal PS1 of the packet switched network source (on the network 3) is given to the user terminal 5 of the present invention in relation to the CS alarm signal CS1, an automatic response is made by the user terminal 5. Recognize that it can be provided.

  The user terminal 5 of the present invention includes an electronic circuit including a CS telephone device CS0 and a packet-switched data processing device PS0. Devices CS0 and PS0 are schematically indicated by dotted squares. Further, the user terminal 5 can include an additional device D0 that can be configured to provide a graphical user interface (GUI) and an application (locally executable) associated with this GUI, as described above.

  The packet switching type signal PS1 is realized using, for example, the Internet protocol (IP).

  A finite state machine FSM is provided inside the CS telephone device CS0.

  A processing application HA for processing packet-switched signals is provided inside the packet-switched data processing device PS0. Further, PS0 may be provided with a storage device or a memory MP for storing data related to the additional packet switching type signal PS1.

  The processing application HA has as its output a connection 40 to the finite state machine FSM in order to send information signals from the processing application HA to the finite state machine FSM. The processing application can obtain information from the additional packet switched signal PS1. Such information signals include at least the response control signal ACS.

  As will be described in detail later, the finite state machine FSM can change its state in relation to the response control signal ACS received from the processing application HA.

  The network service (or network application server) NS on the network 3 can provide the CS alarm signal CS1 together with the additional packet switching type signal PS1 to the user terminal 5.

  Within the network 3, signals CS1 and PS1 are transmitted on the respective bearer services. The CS alarm signal CS1 is transmitted on the first circuit-switched bearer service. The packet switched signal PS1 is transmitted on the second packet switched bearer service.

  The CS alarm signal CS1 is guided to the CS telephone device CS0. The CS alarm signal CS1 will have an interaction with the finite state machine FSM, as described above with respect to FIGS. The finite state machine FSM will change its state to the call waiting state 20 (if it is not busy).

  The finite state machine FSM is configured to expect an additional packet switched signal PS1 in conjunction with the reception of the CS alarm signal CS1. In one embodiment, the finite state machine FSM obtains from the CS alarm signal CS1 that it should expect such an additional packet switched signal PS1. This can be realized, for example, based on a received Caller Line Identity signal or a variation of the CS alert signal CS1. Stores received caller line identification signal or a variant of CS alarm signal CS1 in memory MP to determine whether the CS alarm signal relates to the associated network service or can predict the associated additional packet switched signal PS1 Can be compared with the collected data. In another embodiment, the finite state machine FSM may be configured to expect to receive an associated additional packet switched signal PS1 within a (fixed) predetermined time. In anticipation of the additional packet switched signal PS1, the finite state machine FSM may be configured to delay the generation of an alarm (audible, visual or tactile) to the user. The predetermined time may be such that the CS alarm signal CS1 and the packet switched signal PS1 are received at the user terminal 5 substantially simultaneously.

  Further, although the packet switching type signal PS1 arrives before the CS alarm signal CS1, it may be held until the corresponding CS alarm signal CS1 arrives.

  After reception, the additional packet switching type signal PS1 is guided to the processing application HA in the packet data processing device PS0. The additional packet switching type signal PS1 includes at least response-related data related to the “ongoing” CS alarm signal CS1. The processing application HA is configured to determine from the response related data in the packet-switched signal PS1 whether or not the network service requests execution of an automatic response by the user terminal 5.

  If an automatic response is required, the processing application HA can provide a response control signal ACS on the connection 40 to the finite state machine FSM.

  Upon receipt of the response control signal ACS, the finite state machine FSM changes its state from the “call receiving” state 20 to the “active” state 30 through the intermediate state 25.

  As a result, the user terminal 5 provides the network 3 with a CS response signal CS2 that the pending call has been answered. The voice communication 7 can be started.

  In the above method, the additional packet switched signal PS1 provides a network induced response for the CS telephone device CS0.

  According to the present invention, the transition from the “call receiving” state 20 to the “active” state 30 may be a network induced response (given by the additional packet switched signal PS 1) or a mobile terminated user (mobile terminated user) of the user terminal 5. User) is started with call acceptance.

  The continuation of the established call may be as described above with respect to FIGS.

  FIG. 4 shows a CS call state diagram 4 for the finite state machine of the user terminal 5 according to the present invention.

  The finite state machine FSM of the user terminal 5 is very similar to the prior art finite state machine except that it has the ability to accept primitive ACSs in the CS call state. The primitive ACS is obtained from the response control signal ACS generated by the processing application HA. The primitive ACS may prompt the finite state machine FSM to change from the “receive call” state 20 to the “active” state 30 as indicated by the dotted line.

  The determination step by the processing application HA that the automatic response by the user terminal 5 is to be executed requires that the CS alarm signal CS1 and the additional packet switching type signal PS1 are related in some way. For example, the additional packet switching type signal PS1 may include data related to the CS alarm signal CS1, such as the calling line identification information (CLI) of the speaker A that is normally included in the CS alarm signal CS1. Further, the CS alarm signal CS1 may include some data indicating that the additional packet switching type signal PS1 is transmitted together.

  Furthermore, the processing application can acquire the ID of the network service NS that has transmitted the combination of the CS alarm signal CS1 and the additional packet switching type signal PS1 from the additional packet switching type signal PS1.

  In addition, the processing application can also obtain authentication information about the network service NS from the additional packet switched signal PS1, allowing the processing application HA to confirm the authentication of the network service NS. In this way, the user of the user terminal 5 can surely know the ID of the network service 3.

  Finally, the data of the additional packet switching signal PS1 may include load information indicating the “reason” that the network service NS requested that the user terminal 5 should automatically answer the call.

  Information for at least one of identification, authentication and “reason” included in the signal PS1 enables the processing application HA to apply the service filter FL as to which network services are allowed to respond automatically. .

  The service filter FL comprises data associated with the information described above for identification and / or authentication purposes of the network service NS that transmitted or generated the signal PS1 in the additional packet switched signal PS1.

  The service filter FL may be defined by the user, for example, by an application on the user terminal 5 (possibly using a GUI). The user can use the application to define one or more network services NS that allow the user terminal 5 to automatically answer incoming calls. The application can define service filtering data accessible for use by the processing application HA during the process of determining whether an automatic response can be generated for an incoming call. Service filtering data is typically stored in a memory associated with the service filter FL.

  In one embodiment, the user terminal 5 automatically processes both the CS alarm signal CS1 and the additional packet switched signal PS1 without notifying the user about the incoming message (ie having a silent alarm pattern). ). This process can be executed using, for example, a mobile terminal application such as SIM application toolkit (SAT) and MExE. The processing application HA can use an application programming interface such as J2ME. However, those skilled in the art of the present invention will appreciate that alternative protocols and programming environments may equally be suitable.

  Depending on the actual nature of the incoming call (and its reliability), the present invention generates a combination of CS alarm signal CS1 and additional packet switched signal PS1 either by network service NS or speaker A's A terminal. Make it possible to do.

  FIG. 5 is a diagram showing a signal flow according to the response method of the present invention.

  In the present embodiment, the combination of the CS alarm signal CS1 and the additional packet switching type signal PS1 is generated by the network service NS on the network 3.

  The call setup is started by the A terminal 6 that transmits a CS alarm signal CS1 (or, generally, a CS call setup) on the network 3. In the network 3, the network service NS generates an additional packet switching type signal PS1, and the additional packet switching type signal PS1 is transmitted to the user terminal 5 (or the B terminal 5 not shown in detail) together with the CS alarm signal CS1. As described above, the CS alarm signal CS <b> 1 may be changed so that a silent alarm pattern is transmitted to the user terminal 5.

  As described above, the user terminal 5 generates an automatic response (CS response CS2) based on information received in the combination of the CS alarm signal CS1 and the additional packet switching type signal PS1. The CS response CS2 is transmitted to the network 3 and the A terminal 6 in order to establish the voice communication 7.

  FIG. 6 is a diagram showing another signal flow according to the response method of the present invention.

  In the present embodiment, the combination of the CS alarm signal CS1 and the additional packet exchange type signal PS1 is generated by the A terminal 6.

  Both the CS alarm signal CS1 and the additional packet switching type signal PS1 are generated by the A terminal and transmitted to the user terminal 5 via the network 3. In this case, the network 3 behaves transparently for both CS1 and PS1. Note that the CS alert signal CS1 generated by the CS call setup or A terminal 6 may include a silence alert pattern.

  As described above, the user terminal 5 generates an automatic response (by the CS response CS2) based on the information received in the combination of the CS alarm signal CS1 and the additional packet switched signal PS1. The CS response CS2 is transmitted to the network 3 and the A terminal 6 in order to establish the voice communication 7.

  7a, 7b, and 7c are diagrams showing still another signal flow according to the response method of the present invention.

  In the embodiment of FIG. 7a, the user terminal 5 receives an incoming call from the network service NS on the network 3 together with a CS alarm signal CS1 and an additional circuit switched signal CS3.

  The network service NS generates a network induced response signal CS3 in addition to the CS alarm signal CS1.

  The network induced response signal CS3 is a signal in the CS domain.

  The CS alarm signal CS1 is guided to the CS telephone device CS0. The CS alarm signal CS1 will have an interaction with the finite state machine FSM, as described above with respect to FIGS. The finite state machine FSM will change its state (if it is not busy) to the “call received” state 20.

  The finite state machine FSM is configured to expect the additional circuit switched signal CS3 in conjunction with the reception of the CS alarm signal CS1. The finite state machine FSM obtains from the CS alarm signal CS1 that it should expect such an additional circuit switched signal CS3.

  In anticipation of the additional circuit switched signal CS3, the finite state machine FSM generates an alarm (audible, visual or tactile) to the user, and the additional circuit switched signal (or network induced response signal) CS3 The user terminal 5 may be configured to be delayed for a predetermined time that will be received.

  Further, the circuit switching type signal CS3 arrives before the CS alarm signal CS1, but may be held until the corresponding CS alarm signal CS1 arrives.

  After reception, the additional circuit switched signal CS3 is also led to the finite state machine FSM. The additional circuit switched signal CS3 may include at least response related data relating to the “ongoing” CS alarm signal CS1.

  The finite state machine FSM can be configured to determine from the additional circuit switched signal CS3 whether the network service requires execution of an automatic response by the user terminal 5.

  If an automatic response is requested, the finite state machine FSM changes its state by transitioning from the “call receiving” state 20 to the “active” state 30 through one or more intermediate states 25 and changing the CS response CS2 to the network. 3 (network service NS).

  Next, the voice communication 7 can be started.

  In the embodiment of FIG. 7a, the user terminal 5 receives an incoming call from the network service NS on the network 3 together with a CS alarm signal CS1 and an additional circuit switched signal CS3.

  The network service NS generates an additional circuit switching type signal CS3 in addition to the CS alarm signal CS1. All of these can be transmitted on a circuit-switched bearer service.

  In the embodiment of FIG. 7b, the user terminal 5 receives an incoming call from the calling A terminal 6 together with a CS alarm signal CS1 and an additional circuit switched signal CS3.

  The A terminal 6 that has made an incoming call to the user terminal 5 generates an additional line switching type signal CS3 in addition to the CS alarm signal CS1. All of these can be transmitted on a circuit-switched bearer service.

  In this case, the network 3 behaves transparently to both CS1 and CS3. Note that the CS alert signal CS1 generated by the CS call setup or A terminal 6 may include a silence alert pattern.

  As described above with respect to FIG. 7a, the finite state machine FSM is configured to determine from the network induced response signal CS3 whether the network service is requesting execution of an automatic response by the user terminal 5.

  If so, the finite state machine changes its state by transitioning from the “call receiving” state 20 to the “active” state 30 through one or more intermediate states 25 and changing the CS response CS2 to the network 3 (and A To the terminal 6). Next, the voice communication 7 between the A terminal 6 and the user terminal 5 can be started.

  In the embodiment of FIG. 7c, the user terminal 5 receives an incoming call together with a CS alarm signal CS1 and an additional packet switched signal PS1 including an invitation signal IS1.

  The additional packet switched signal PS1 on the packet switched bearer service can be generated by the network service NS or the calling A terminal 6 as described above with reference to FIGS. 5 and 6, respectively.

  The processing application HA is configured to extract the invitation signal IS1 from the additional packet switching type signal PS1 and transmit the invitation signal IS1 to the additional device D0. The additional device D0 is configured to process the invitation signal IS1 by some application using a GUI, and this application presents information regarding an incoming call to the user. After receiving a feedback signal FS for this information from the user, the user terminal sends a feedback signal FS (information relating to packet switched type) to the network service NS over the PS bearer service.

  The network service NS is configured to recognize a feedback signal from the user terminal 5. As a result, the network service NS responds by transmitting the induced CS response signal CS3 to the user terminal 5 over the circuit-switched bearer service, and a packet-switched signal including the invitation signal IS1 is sent to the user terminal CS0. Notify about user interaction with PS1. The finite state machine FSM receives the network induced CS response CS3 and changes its state to the “active” state 30. As a result, the CS telephone type device CS0 transmits a CS response CS2 to the network 3 (network service NS and / or A terminal 6).

  If necessary, voice communication 7 can be established at this point.

  FIG. 8 is a signal diagram for another embodiment of the response method of the present invention.

  In the present embodiment, the combination of the CS alarm signal CS1 and the additional packet switching type signal PS1 is generated by the network service NS on the network 3 as in the embodiment shown in FIG.

  The call setup is started by the A terminal 6 that transmits the CS alarm signal CS1 to the network 3. In the network 3, the network service NS generates an additional packet switched signal PS1 on the packet switched bearer service, and the additional packet switched signal PS1 sends a CS alarm to the user terminal 5 (or B terminal 5 not shown in detail). It is transmitted together with the signal CS1. As described above, the CS alarm signal CS <b> 1 may be changed so that a silent alarm pattern is transmitted to the user terminal 5.

  The additional packet switched signal PS1 has a ring delay signal RS containing information about the number or time of rings until the automatic CS response CS2 is transmitted to the network 3. The processing application HA processes the additional packet switching type signal PS1 and extracts the call delay signal RS information. On connection 40, the processing application HA sends a call delay signal RS (information about) to the finite state machine FSM. The finite state machine FSM determines from how many ringing tones (or when) it changes from the “call reception” state 20 to the “active” state 30 and sends the CS response signal CS2 to the network 3 from the received call information. To do.

  As described above, the CS response CS <b> 2 is transmitted to the network 3 and the A terminal 6 in order to establish the voice communication 7.

  FIG. 9 is a CS call state diagram in another embodiment of the answering method of the present invention.

  In this embodiment of the present invention, user terminal 5 gives A terminal 6 the privilege to “interrupt” the first other call conversation that may be ongoing between user terminal 5 and another A terminal. ing. In this situation, the present invention can provide a “(network induced) forced call hold” as will be described below.

  The principle of “call hold” is described in GSM TS 04.83 v.7.0.1. Chapter 2.1.5 of GSM TS 04.83 describes the “call hold” status. The “call hold” state is considered herein as an auxiliary state that is part of the general “active” state 30.

  The privileged A terminal 6 sets up a call to the user terminal 5 and includes a “forced call hold” command in the call setting. Alternatively, the network service NS can provide a “forced call hold instruction” instead of the privileged A terminal 6. This “forced call hold” command is carried on the bearer service in the PS domain as an additional packet switching type signal PS 1. This “forced call hold” command is processed when received by the user terminal 5. It may have the effect of causing the application HA to provide a hold signal or hold primitive HS on the connection 40 to the finite state machine FSM.

  The finite state machine FSM depending on the actual state of the user terminal 5 at the time when a privileged A terminal call arrives, ie, the “free” state 10 (= idle) or the “active” state 30 (= busy). Can vary the interpretation of the hold signal HS.

  During the “free” state 10, the finite state machine FSM can change its state to the “receive call” state 20 (as described above) and ignore the “hold” signal (in this case, the incoming call is spoken) It can be handled by the person B as a normal call in the prior art). Alternatively, in accordance with one or more of the embodiments described above, the finite state machine FSM interprets the “hold” signal HS as a network-induced command to automatically answer an incoming call and changes it to the “active” state 30. Can do.

  However, when the hold signal enters the finite state machine FSM during the “active” state of the first other call, the finite state machine FSM (as indicated by arrow H1) The state is changed to the “hold” state 45, and the state of the incoming call from the privileged A terminal 6 is changed to the “active” state (arrow H2).

  After the call from the privileged A terminal 6 is disconnected, the finite state machine returns its state to the previous state. That is, the first other call that is "on hold" (in the "hold" state) is searched and returned to the "active" state (arrow H3). If there are no other calls, change to the “free” state.

  Transitioning other calls from the “active” state 30 to the “hold” state 45 and transitioning other calls from the “hold” state 45 to the “active” state 30 are essentially according to the GSM TS 04.83 specification. Can be executed. The additional packet switching type signal PS1 (network induced type signal) according to the present invention instructs the user terminal 5 to execute one of the operations H1 and H3.

  Inclusion of “forced call hold” may be performed manually by speaker A. Alternatively, the inclusion of “forced call hold” may be automatically executed by the A terminal 6 by some recognition procedure of the B number of the user terminal 5.

  For example, the B number of the user terminal 5 and the display of the application of “forced call hold” for the B number can be stored in the memory of the A terminal. At this time, since the terminal A automatically transmits a “forced call hold” command, data stored in the memory can be used.

  Furthermore, the additional information (in the “forced call hold” command) in the additional packet switched signal PS1 must be presented at the user terminal 5 and / or the other A terminal in the first other call (speaker at the individual terminal). References to announcements (auditory or visual on the display) may be included.

  For example, the user terminal 5 who is about to be automatically connected to the speaker of the privileged A terminal 6 can receive an appropriate announcement by a speaker of another A terminal that is going to be placed on hold. Speaker B can receive an appropriate announcement. These announcements may be different. The announcement can be provided from the network service NS in response to the announcement signal from the user terminal 5 in the PS domain.

  The additional information in the additional packet switching type signal PS1 further indicates that a network-induced “forced call hold” occurs after a specified number of calls (for example, three ringing sounds) to the user terminal 5 of the speaker B. You can be notified. This allows speaker B to answer the phone himself instead of “answered”.

  Network-induced "call hold" would be useful as an extension of applications that provide audio content during route guidance through a mobile phone while traveling by car. When a driver expects directions information (eg, “next highway exit”), the driver expects this information even if he / she is on a call. Thus, the voice directions information should automatically hold the ongoing conversation, possibly play the announcement, disconnect, and restore the original call.

  The method for the user terminal 5 according to the invention can be implemented in hardware and / or software. In the case of software, the user terminal 5 includes a processing unit and a memory connected to the processing unit. The user terminal 5 can load a computer program for executing the above-described method. After loading the computer program, the processing unit of the user terminal 5 is configured to execute the program so as to obtain the functions described above.

  Similarly, the software program can also be used inside the network service 3 and / or the calling A terminal 6 to obtain the functions as described above with respect to the network service NS and the A terminal 6, respectively.

  The present invention can be implemented in various applications for the user terminal 5.

  In the first CS type application, the user terminal 5 is configured to receive the audio content of the guided tour. The user terminal 5 may be any appropriate mobile communication device according to any one of the embodiments.

  Each time new content becomes available (eg, depending on the location of the user terminal 5), the CS application initiates a call to the user terminal 5 with the additional packet switched signal PS1. Individual calls are automatically answered without requiring a user response in accordance with one or more of the embodiments described above.

  In another application, the user terminal 5 is configured to have a monitoring phone (babyphone) function. The user terminal 5 can be installed in a room where children, for example, infants are present. All calls to the user terminal 5 are communications for recording sound from the room. The call includes an additional packet switched signal PS1 for automatic answering to the call, and may further include instructions for a silent alert pattern.

  The monitoring telephone can be realized by any one of the above-described user terminals, and the user terminal is a CS telephone apparatus for processing CS telephone signals CS1 and CS2 received and transmitted on a circuit switched bearer service. At least a CS0 is configured to communicate over a telecommunications network. The user terminal is configured to receive the additional response related signal PS1; CS3 associated with the incoming incoming CS alert signal CS1. Further, the user terminal is configured to transmit a response signal or a CS response signal CS2 on the circuit-switched bearer service in response to information included in or obtained from the additional response related signal.

  In another application, the present invention provides network-induced call hold as described above. The A terminal 6 calls the user terminal 5 of the present invention. The user terminal is in a call with another terminal. As described above, A terminal 6 is given the privilege of “interrupting” calls in progress. The user of the A terminal can receive the “busy” signal and give a command on the A terminal 6 to hold the user terminal 5 on hold and to force the A terminal to be connected by voice communication. . This command gives an opportunity to generate the additional packet switching type signal PS1 to be made to respond to the A terminal 6 when the user terminal 5 receives it. Other calls are put on hold. Other callers can be presented with a message that the call will be put on hold.

  In yet another application, the present invention provides network-induced “call hold” as described above. The A terminal 6 calls the user terminal 5 of the present invention. The user terminal 5 is in a call with another terminal. As described above, A terminal 6 is given the privilege of “interrupting” calls in progress. In this case, no user operation at the A terminal is required. The busy signal is not transmitted to the speaker of the A terminal 6. The additional packet switching type signal PS1 may be directly transmitted together with the call setting signal, or may be generated by the network service NS when a busy signal is detected for the user terminal 5. The user terminal 5 responds to the A terminal 6 and other calls are “held”. Other callers can be presented with a message that the call will be “held”.

  While specific embodiments of the invention have been described, there is no intention to limit the invention to these embodiments. The invention may be integrated with any other alternatives, modifications or equivalents and is limited only by the scope of the appended claims.
