Abstract

(57) [Summary] The group call server provides a call type indication and other additional information to a specific type of communication terminal so that these calls can be distinguished from other types of calls. Supply. When the target communication terminal receives this information and operates based on this information, the group call server that supervises the group call sends a paging message sent to the outside with one or more display flags. The user number field can be selectively increased. The display flag indicates one or more characteristics of the group call, such as call type, call special type or priority. One flag may indicate the priority and the other flag may indicate the call special type of the group call. The response, such as whether or not the communication terminal receiving the increased paging message should automatically respond, is based on the characteristics of the group call indicated in the paging message. Since the group call server is inherently flexible over existing signaling protocols and air interface protocols, the method disclosed herein can be implemented without requiring changes to the BMi air interface.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION The present invention relates to the field of communication systems, and more particularly to a method of handling group calls in a communication system such as a wireless communication system.

The use of portable wireless communication devices such as cellular phones, personal communication assistants, etc. is rapidly increasing in society. These wireless communication devices are beginning to become prevalent in a wide variety of configurations, depending on their intended use. For example, the mobile terminal of an ordinary cellular telephone, which is a traditional land-based telephone, has the added functionality of portability and storage of multiple telephone numbers, attempting to mimic the land-based telephone. One feature of land-based phones that is retained on most cellular phones is:
It is possible to be involved in full duplex communication. In general one-on-one conversation, both parties can speak at the same time by the full-duplex method. This is in contrast to the prior art of mobile trunk radiotelephones where only one party can speak at a time. In addition, conference call capabilities or other multi-party ca capabilities.
availability), two or more parties can generally speak at the same time. For ease of reference, this full duplex mode will be referred to as the "telephone mode". The details of telephone mode operation in a cellular telephone are well known in the art.

Some cellular telephones are not only capable of operating in telephone mode, but also in what is referred to herein as wireless mode. An example of this dual mode device is US Pat. No. 5,450,618, US patent application Ser. No. 09 / 361,94.
1 and 09 / 361,747, all of which are incorporated herein by reference, and British Patent Application No. 9214180.3. In wireless mode, the phone appears to the user to handle communications in half-duplex fashion. That is, the cellular telephone does not appear to the user to simultaneously transmit and receive voice data. Instead, the user must press a button, commonly known as a push-to-talk (PTT) button, so that the transmitted data includes data corresponding to the user's voice. Otherwise, the phone appears to be receive-only. In addition, dual mode telephones typically automatically answer incoming calls when in wireless mode.

With increasing frequency, cellular phones, other mobile phones and communication terminals are commonly used for group calls. A group call is a specific type of call in which a caller attempts to communicate with one or more members of a given user group. Members of a given group are contacted using a wide variety of devices such as traditional land telephones, cellular telephones, satellite telephones, personal communication assistants, pagers and the like. The most common type of group call is a conference involving a given set of users on a set of phones, such as all engineers for a project. Another type of group call is a broadcast group call from one location to all listening members, such as a group call from a police station to all patrol officers in a given province. One common feature of group calls is that less than all group members may participate in any given group call, but who can participate in a group call other than the caller of the group call ( That is, the list of group members) is known prior to the initiation of the call.

As mentioned above, many communication terminals, such as dual mode telephones, typically automatically answer incoming calls when in wireless mode. However, just because a phone answers a call does not necessarily mean that the user is actually about to land on the phone. Instead, perhaps the user has a telephone in auto-answer mode, such as in wireless mode, but does not attend this telephone. If so,
Incoming calls are answered, callers are faced with the daunting task of speaking to a telephone without a user, and in the context of group calls, this auto-answer feature can pose particular problems. It is often desirable for a phone not to automatically answer group calls, or at least certain types of group calls.

[0006] In doing so, the communication terminal can determine whether the incoming call is a group call before answering the group call, and optionally a group rather than a "normal" call. A mechanism is needed that can determine more detailed characteristics of some of the calls. However, there is no known method by which the mobile terminal determines when the call is a group call or a non-group call (or other form of group call). Therefore, there remains a need for a method of displaying to a communication terminal, such as a wireless communication mobile terminal, when an incoming call is a group call so that the communication terminal can respond appropriately. Optionally such a method
The communication terminal may further fine tune its response to the call, as it may also provide more detailed information about the group call.

SUMMARY OF THE INVENTION The present invention provides a communication terminal with a call type indication for a group call and optionally other information about the group call so that the group call can be identified from other types of incoming calls. To do.

In one exemplary embodiment, the group call server that governs the group call receives the information in the calling party number field of the outbound paging message by the targeted communication terminal and based on this information. When activated, this calling party number field is selectively augmented with one or more display flags. The display flag is
Indicates one or more characteristics of call type, call special type, or priority. Upon receiving a group call request, the group call server of the present invention consults the database for that user group. The user group database contains records corresponding to group members of the requested user group. This record preferably includes an indication of the device type of the corresponding device for each call address (eg telephone number).
If the device type is shown to be of a particular type corresponding to the communication terminal adapted to cooperate with the present invention, the group call server (eg enhanced terminal) may include additional information. Change the calling field of the paging message to. Otherwise, the group call server proceeds as in the prior art. For example, the group call server can increment the calling party number to add one or more display flags. As an example, the first flag may indicate priority and the second flag may indicate group call. In short,
The group call server initiates a paging message containing additional information about the group call for the enhanced terminal.

The present invention further provides a mobile communication terminal that is more suitable for handling group calls. A communication terminal, such as a dual mode wireless mobile terminal operating in wireless mode, receives a paging message for a group call and selects an appropriate response to the paging message based on the flag character. The mobile terminal preferably examines the calling field of the paging message to indicate the presence of the flag character. If the flag character is present, the mobile terminal dissects the flag character and the caller ID. Based on the flag character, the mobile terminal determines an appropriate response to the paging message. This response may include, for example, controlling the man-machine interface of the mobile terminal and automatically determining whether to answer the call. In the preferred embodiment, the mobile terminal automatically answers certain types of group calls and requires manual intervention by the user before answering paging calls for other types of group calls. Therefore, the mobile terminal of the present invention receiving the increased paging message is based on the characteristics of the group call indicated in the paging message, such as whether or not to automatically answer.

In its preferred embodiment, the present invention is still compatible with existing installation systems, such as ANSI-136, while both its enhanced group call server and enhanced communication terminal provide this added functionality. I try to go back in time and continue to be compatible. That is, in the preferred embodiment, the present invention relies on the flexibility already built into the existing Air Interface Protocol. Accordingly, the present invention is based on a signaling protocol and an air interface protocol or a BMI (Base station, Mobile switch).

Detailed Description of the Preferred Embodiments Although the following description is directed to a cellular radiotelephone system, the present invention is
It is not necessarily limited to that environment. In particular, the following description refers to ANSI-1
Described using terms that may be relevant to 36-compliant systems,
The present invention may be implemented in wireless communication environments designed according to other standards, such as GSM, IS-95 or PDS, as well as other wireless communication environments including various access methods, such as wireless communication environments using CDMA. Good.

One embodiment of a mobile terminal suitable for use with the present invention is shown in FIG. 1 and is generally indicated by telephone 20. Although the illustrated mobile terminal is a digital cellular telephone, the present invention is not so limited and encompasses a wide variety of wireless communication devices including cellular telephones, personal communication assistants, pagers and the like. Furthermore, the present invention is not limited to wireless mobile terminals, but encompasses land-based communication terminals or other types of communication terminals, including Internet-based communication terminals capable of receiving incoming group calls. However, for simplicity of description, a dual mode wireless communication mobile terminal is used herein as the main illustrative example. In particular, the telephone 20 shown in FIG. 1 is used as a main explanation example. The telephone 20 is preferably a dual mode telephone capable of telephone mode and wireless mode operation, as described below.

The cellular telephone 20 generally has a control device 22, an operator interface 26, a communication device 38, a receiver 50, and an antenna device 58. The operator interface 26 generally comprises a display 28, a keypad 30, a control unit 32, a microphone 34 and two speakers 80,85.
The display 28 allows the operator to view dialed digits, call status and other service information. The keypad 30 allows the operator to dial numbers, enter commands, and select options. Control unit 3
2 interfaces the display 28 and the keypad 30 to the controller 22.

The microphone 34 receives an acoustic signal from a user and converts the acoustic signal into an analog electric signal. Speakers 80 and 85 convert the analog electrical signals from receiver 50 into acoustic signals that can be heard by the user. The first speaker 80 is a low volume that is typically placed over the display 28 to approach the user's ear when the phone 20 is held against the user's head in a traditional telephone handset position. It is a speaker. The second speaker 85 is a high volume speaker that is typically located at the opposite end of the phone 20 with respect to the low volume speaker 80. See FIG. The low volume speaker 80 acts as the main speaker of the phone when the phone is in "phone mode" and the high volume speaker 85 is in "wireless mode" as described in detail below.
Works as the main speaker of the phone. Switches (not shown) may optionally be provided in the circuitry leading to speakers 80 and 85 to route the acoustic output to one speaker or another. Such a switch shall operate under the control of controller 22 either directly or indirectly.

The keypad 30 comprises a plurality of keys having at least a first key 70 and a second key 75. In this figure, the first key 70 is a send key and the second key is a PTT key. It should be noted that the keys on keypad 30 may be physical keys or virtual keys (as shown on display 28) and these keys need not be located in only one area of telephone 20. Absent. Send key 70
Are preferably located some distance from the PTT key 75. For example,
The send key 70 may be located on the front side of the telephone 20 in close proximity to a regular 3x4 telephone key array, while the PTT key 75 may be located on the side of the telephone 20 near the display 28. See FIG.

The analog electrical signal from microphone 34 is sent to transmitter 38. The transmitter 38 includes an analog-to-digital converter 40, a digital signal processor 42, and a phase modulator / RF amplifier 48. The analog-digital converter 40 is
The analog electric signal from the microphone 34 is converted into a digital signal. This digital signal is sent to a digital signal processor (DSP) 42, which
2 has a speech coder 44 and a channel coder 46. The speech coder 44 compresses the digital signal and the channel coder 46 inserts error detection, error correction and signaling information. The DSP 42 may have or operate with a DTMF tone generator (not shown). The compressed and encoded signal from the digital signal processor 42 is the phase modulator and RF amplifier 48.
Sent to. The phase modulator / RF amplifier 48 is shown as a combination unit in FIG. The modulator converts the signal into a form suitable for transmission on an RF carrier. The RF amplifier amplifies the output of the modulator for transmission via the antenna device 58.

The receiver 50 comprises a receiver / amplifier 52, a digital signal processor 54 and a digital-to-analog converter 56. The signal received by the antenna device 58 is sent to the receiver / amplifier 52. The receiver / amplifier 52 shifts its frequency spectrum and amplifies its low level RF signal to a level suitable for input to the digital signal processor 54.

The digital signal processor 54 is generally based on an equalizer that compensates for phase and amplitude distortions of the channel-corrupted signal, a demodulator that extracts a bit sequence from the received signal, and the extracted sequence. A detector for determining the transmitted bits. The channel decoder detects and corrects a channel error in the received signal. The channel decoder also has logic circuits that separate the control signaling data from the speech data. The control signaling data is sent to the control device 22. The speech data is processed by a speech decoder and digitally processed.
It is sent to the analog converter 56. Digital signal processor 54 may have or may operate with a DTMF tone detector (not shown).

The digital-analog converter 56 converts the speech data into an analog signal,
This analog signal is applied to one of speakers 80 and 85 to produce an acoustic signal that can be heard by the user, as described in more detail below. The antenna device 58 is connected to the RF amplifier of the transmitter 38 and the receiver / amplifier 52 of the receiver 50. The antenna device 58 is typically a duplexer 60.
And an antenna 62. The transmission / reception switch 60 uses the antenna 6 as necessary.
Allow full duplex communication via 2.

The controller 22 coordinates the operation of the transmitter 38 and the receiver 50 and may take the form of a conventional microprocessor, for example. The coordination includes power control, channel selection, timing and many other functions. The control device 22 inserts the signaling message into the transmission signal and extracts the signaling message from the reception signal. Controller 22 responds to and executes any base station commands contained in the signaling message. When the user enters a command via the keypad 30, the command is transferred to the controller 22 for execution.

The memory 24 stores and supplies information according to a command from the control device 22, and preferably has both a volatile portion and a non-volatile portion. In the memory 24,
A plurality of memory locations 90 are included for storing call addresses. Figure 3
reference. These memory locations 90 may be considered to be divided into at least two sections, a first section 92 and a second section 94. The first section 92 has the first N memory locations 90 of the call address and the second section 94 has the balance. For illustration, N is assumed to be 25, but any number greater than 1 may be used. The user enters the call address to be stored in memory location 90 via any method known in the art. The memory location 90 may fill non-continuously. For example, it is expected that memory locations 1, 4, 8, 10, 24 and 35-45 may be filled and the rest empty.

The telephone 20 preferably operates in both telephone and wireless modes. The telephone mode may be the telephone 20 in any manner known in the art, such as ANSI-136.
It is simply a telephone operating mode characterized by a full duplex system. In telephone mode, the conversation appears to the user of telephone 20 to be bidirectional at the same time. This property is typical of prior art digital cellular phones. Wireless mode is an operating mode of the phone 20 that appears to the user to operate in half-duplex mode to the user. In wireless mode, the conversation appears bidirectional to the user of phone 20, but not simultaneously. Instead, the operation of microphone 34 and speaker 85 are mutually exclusive during the call. When the PTT key 75 is pressed, the microphone 34 of the telephone 20 is activated, and when the PTT key 75 is not depressed, the speaker 85 is activated. For ease of reference, the state of the PTT key 75 corresponding to the actuation microphone 34 may be referred to as the "speak position", and the state of the PTT key 75 corresponding to the actuation speaker 85 may be referred to as the "listening position." This type of operation is familiar to existing trunk radiotelephone users. Thus, in the wireless mode, the telephone 20 resembles the man-machine interface of a trunk radio telephone.

As much as possible, the wireless mode behavior of the telephone 20 should be limited to the telephone 20. This means that the communication between the telephone 20 and the rest of the wireless communication system is as a digital cellular telephone in telephone mode, but the Man-Machine interface is to the user a trunk wireless telephone. Seems to be. Thus, when the telephone 20 operates in wireless mode, the telephone 20 may appear to be either full-duplex or half-duplex to the rest of the communication system. The only requirement for the telephone to operate in wireless mode is to have the telephone 20 appear half-duplex to the user, irrelevant to the reality, from the perspective of the communication system. Wireless mode operation of the telephone 20 is further disclosed in co-owned US patent application Ser. No. 09 / 234,191, which is incorporated by reference herein.

Generally, the user fills one or more of the available memory locations 90 with call address information. The call address information is typically an ordinary telephone number, such as that associated with other cellular or traditional land telephones or computers. In addition, there may be alphanumeric identification tags associated with each call address, such as names. The term "call address" is used herein rather than "phone number". This is because the call address information may be a telephone number, but may instead be a group identification number used to establish a group call.

A group call as described above is a special type of call in which a caller seeks to communicate with one or more members of a predefined group. Group calls exist in many types of call types. Two common call types are broadcast and interactive. In the case of a broadcast type, the main information flow during a group call is one way from one source (caller) to one or more destinations <group members>. Thus, in the case of a broadcast type group call, only the caller of the group call can speak and the recipients are limited to listening. In the case of an interactive group call, the main information flow during the group call may be bidirectional. Thus, in the case of an interactive group call, both the caller and the participating group members may both both speak and listen.

Each call type may be further classified into a call special type. For example, interactive group calls may be further classified into a sequential type, a simultaneous first response special type, and a conference special type. In the case of sequential special type group calls, the wireless communication system that manages the calls sequentially attempts to contact the group members, giving each member a chance to answer before proceeding. In the exemplary configuration, the call is routed to the first group member. If the first group member does not answer in a timely manner, the call is canceled and the second group member is called, and so on. Thus, a sequential special type of group call may be considered as a series of individual calls connected in a chain to the group members in a predetermined order. In this case, the caller does not have to dial each number serially, but instead may dial a single group identification number. A simultaneous first answer special type group call is similar to a sequential special type group call, but the call is sent to all group members at the same time and the call is connected to the first group member that answers the call. It A conference special type group call is similar to a simultaneous first answer special type group call, but all group members who answer the call are concatenated to the call. Thus, both the sequential special type group call and the simultaneous first response special type group call, if successful, result in a group call between the calling party and one group member. In contrast, a conference special type group call, if successful, results in a group call between the calling party and one or more group members.

[0027] Traditional dual-mode phones, ie, phones that automatically answer incoming calls in wireless mode, present problems with sequential special-type and simultaneous first-answer special-type group calls. For these calls, the search to find the group member ends when the group member answers. If the user sets the traditional dual-mode phone to wireless mode and leaves the phone unattended for any reason, the phone will still answer incoming group calls. If the telephone receives sequential special type or simultaneous first answer special type calls, the unmanned telephone answers the call and the caller receives an indication that the group call has been answered. However, the caller does not actually communicate with the live user, but instead speaks to the drone. Therefore, the caller is required to speak or leave a message in a thin air. In many situations, the caller need not leave a message, but instead speak to a living individual. In the case of conventional technology, the usefulness of group call is
Disabled, the caller is frustrated by the unattended but answering phone until a user who is not present at some midpoint in the future returns to the phone.

The present invention provides a particular telephone with a call type indication for a group call and optionally other information for this group call so that the group call can be distinguished from other types of calls. And deal with other issues. To do so, the present invention envisions a group call server in charge of a group call to selectively increment the calling party number field of an outbound paging message with one or more display flags. For example, the calling party number field of the ANSI-136 call number for the SPACH channel (ANSI-136-123 §5.3.9 and §6.2).
3) may increase the length. Since the length of the calling field of the paging message can be easily changed within the existing air interface protocol, the present invention can be implemented without the need to change the air interface or BMI. Based on that additional information, the receiving telephone can, for example,
Sequential special type group calls may be determined rather than automatically answered.

In general, group calls are handled by a group call server associated with the wireless communication system. A group call server is a logical part of a wireless communication system that manages group calls, such as by tracking membership of user groups, controlling access to user group functionality, coordinating the flow of information, etc. is there. When the wireless communication system receives the group call request, the request
Sent to the group call server. Other parts of the wireless communication system cooperate with a group call server to facilitate group calls.

The group call server generally has a call address of each group member (
For example, it has a database of user groups <plurality> in which telephone numbers are listed. In the case of the invention, the database of the group call server preferably also contains an indication of the device type of each call address. For example, the device type is
It may be a conventional prior art cellular telephone or it may be a traditional land-based telephone. Of particular interest to this description, one of the device types is
It shall respond to a wireless communication device (eg, a telephone) applied in accordance with the present invention. For purposes of description only, and not for purposes of illustration, this wireless communication device will be referred to as an enhanced terminal. Therefore, the records in the database of the group call server should preferably have an indication as to when a particular call address corresponds to and not to the enhanced terminal type.

In FIG. 4, a group caller generally initiates a group call by dialing a pre-assigned user group identification number (box 210). In the United States, this group identification number typically consists of ten numbers, much like a regular telephone number. When the wireless communication system receives a group call request (box 220), the request is sent to the group call server for handling (box 230). As shown in FIG. 4, the caller may optionally be given the opportunity to select group call settings such as call type, call special type, etc. (box 240), for example by voice interaction. In another embodiment,
The call type and the like are preset for each user group. It should be noted that the selection of group call settings (box 240) may be made after the group call server has been involved (box 230) or earlier. The particular timing is a matter of taste.

After receiving the notification of the request from the wireless communication system (box 230), the group call server consults its database to determine which call address belongs to the requested user group and makes a group call. The setting procedure is started (box 250). The group call server interacts with the balance of the wireless communication system to call a group member with a stored call address in an appropriate manner depending on which call type and call special type was selected. However, before the call is initiated, the group call server looks up the device type indicated in the database record for the relevant group member. If the device type indicates that the called mobile terminal is an enhanced terminal, the group call server increments the calling field of the paging message to include one or more flags indicating the group call setup. Yes (box 260). For example, if the group call is a sequential special type, a flag value of "1" can be added to the calling field. If the group call is a conference special type, a flag value of "3" is added. If the group call is a broadcast type, a flag value of "4" is added, and so on. Preferably, only paging messages intended for enhanced terminals are increased and paging messages intended for other device types remain unchanged. This avoids the confusion of existing systems and mobile terminals (these are not of the invention), and the improved system and mobile terminals of the invention can provide enhanced features while at the same time This is because it is necessary to go back in time and maintain compatibility.

The paging message is sent to the corresponding mobile terminal by the corresponding part of the wireless communication system (box 270). If the targeted mobile terminal is an enhanced terminal, the targeted mobile terminal receives a paging message (box 280) and then checks for an increase (box 285). If this increase is not present, the mobile will automatically answer the call. When the mobile terminal 20 determines that an increase is present, it parses the flag character from the calling party ID in the calling party field (box 285). The mobile terminal then consults the response look-up table in memory to determine how to respond (box 290). In the figure, this response lookup table is Brod
The mobile terminal is instructed to automatically answer the case call and the conference group call, but it is instructed not to automatically answer the sequential group call and the simultaneous first answering group call. Based on the answer lookup table, the enhanced terminal, the mobile terminal, answers the call (box 290), for example by issuing an alert, such as an automatic answer or an audible tone. Therefore, for these mobile terminals enhanced according to the invention, a feature of the auto-answer is that they can be selectively disabled in the case of a group call in radio mode depending on the characteristics of the group call.

In addition to call type, a group call may have a priority assigned to this group call. For example, "normal" priority may be the default for most group calls, but the caller may change the priority to "warning" for more urgent group calls. You may In such a situation, two display flags may be used and the response of the mobile terminal, which is an enhanced terminal, may be according to the following table:

[0035]

[Table 1]

As can be seen in Table 1, the characters used in the display flags include characters that are not normally used, such as “ ^* ” or “#”, or at least to facilitate detection of the presence of the display flag. , You should start with characters you don't normally use. asdf

It should be noted that the calling party may generally initiate a group call in one of two ways. First, the caller may call a publicly defined user group identification number. This user group identification number is publicly defined in that any user calling the user group identification number will reach that same user group if the user is authorized to access the user group. There is. A group call initiated in this way will be referred to as a "pilot" group call. In the United States, pilot group identification numbers typically consist of 10 digits in length. The wireless communication system receiving the group identification number in the dial digit field sends the call to the group call server for handling. The group call server then determines the qualifications of the group members associated with that group identification number and proceeds to set up the group call. Alternatively, the caller of the group call may initiate the group call by dialing a privately defined group identification number such as " ^* 12". A group call initiated in this way will be referred to as a "private" group call. Unlike pilot group numbers, private group numbers may have different meanings for different users. When the wireless communication system receives " ^* 12" in the dial digit field, the wireless communication system recognizes this as a group call request and sends this request to the group call server. Instead, the group call server determines which user group to call based on the dialed digit " ^* 12" and the particular subscriber who made the call. Therefore, if subscriber A is " ^* 12"
Dialing, the group call server makes a group call to a different user group than if subscriber B dialed " ^* 12".

Preferably, the group call server handles pilot group calls differently than private group calls. For private group calls, the calling party number included in the paging message shall be the calling address of the calling party. However, in the case of a pilot group call, the calling party number included in the paging message is preferably the pilot group number. Thus, for a private group call, the receiving terminal programmed to display the caller ID displays the calling party's number, and for a pilot group call, the receiving terminal displays the user group's pilot number. indicate. It should be noted that various settings that regulate the operation of the group call server in some systems may prevent the use of pilot numbers instead of calling party numbers, for example, to comply with local laws.

As an example of using both the pilot / private option and the priority option above, the calling party unit 888 444-1111 has a group identification number 99.
Suppose we initiate a sequential pilot group call with alert priority by dialing 9 555-2525. In addition, the user group is
It is assumed that there are three group members, the first and second group members having enhanced terminals and the third group member having conventional mobile terminals.
The group call server that sent this request initiates a paging message to the first group member. Since the first group member has an enhanced terminal as shown in the group call server database, the paging message has a calling party field with 9995552525 # 1 as the calling party ID. The mobile terminals of the first group member shall not automatically answer the call due to the presence of the suffix "# 1" in the calling party field.

If the first group member does not manually answer within a predetermined time, the call switches to the second group member. This call is also called 9 in the calling field.
Similarly, the mobile terminal of the second group member (also the function-enhanced terminal device type) having the 995552525 # 1 is not automatically answered. If the second group member does not answer in a timely manner, the call switches to the third group member. However, since this group member does not have an enhanced terminal, the suffix "# 1" is not added to the caller ID of its paging message.
Upon receipt of the paging message, the mobile terminal of the third group member will automatically answer the incoming call if programmed to do so, but with the presence of the optional display flag of the present invention. , Absent or content independent.

If the same caller modifies the scenario to initiate a normal priority conference-type private group call by dialing " ^* 12", the group call server will see at least two Start paging message. For the first and second group members, the paging message is
It has a calling party field with the number 8884441111 ^* 3. For the paging message of the third group member, the calling field has the suffix " ^* 3".
With the number 8884441111 as the Caller ID without. With this configuration,
All receiving mobile terminals automatically answer the call into a conference type group call.

The response of the enhanced terminal type mobile terminal 20 has been described as to whether or not to automatically answer the group call, but other answers are possible. For example, based on the information provided by the display flag, the mobile terminal 20 of the present invention modifies the information displayed on the display 28 of the mobile terminal according to the characteristics of the incoming group call, or warns those signals. (For example, ring sound, ring volume, generated vibration, etc.) can be changed. By way of example, the display 28 of the mobile terminal 20 may have more than two lines, an upper line, a middle line and a lower line for ease of reference.

Based on the information provided by the display flag and the comparison of the received call ID with the call address stored in the first portion 92 of the memory 24, the mobile terminal 20
A) If a match with the memory record occurs and the priority is normal priority, the upper display line displays the alphanumeric tag associated with the matching memory record, the middle display line displays the call ID, and b ) If a match with the memory record does not occur and the priority is normal priority, a general text message (for example, "group") is displayed on the upper display line, the call ID is displayed on the middle display line, and c) If If a match with a memory record occurs and the priority is a warning priority, the upper display line displays a warning text message (eg, "warning") and the middle display line displays the alphanumeric tag associated with the memory record,
d) If there is no match with the memory record and the priority is the normal priority, the warning text message may be displayed in the upper display line and the call ID in the middle display line.

Further, the mobile terminal 20 may display an indicator indicating whether the group call is a special type, a simultaneous first response special type, a conference special type, or a broadcast type sequentially with a downward line. For example, the lower line is "S" when the group call special model is a sequential special model.
“EQ”, “SIM” is displayed when the group call special model is the simultaneous first response special model, “GRP” is displayed when the group call special model is the conference special model, and “BDCAST” is displayed when the group call model is broadcasting. May be. As another example, the mobile terminal 20
May make a loud sound with a specific sound when a group call with a warning priority is detected, and “Warning” may be displayed on the display 28, and a special sequence with a normal priority may be displayed. The type of group call may only end with a low level vibration and display of caller ID. Of course, these responses of mobile terminal 20 may be preset at the factory or may be user selectable to provide maximum flexibility.

The above has been made with respect to the fact that the group call server modifies the paging message under certain circumstances related to the target mobile terminal device type. It should be noted that the paging message itself may be completely present on part of the SPACH or equivalent control channel. Alternatively, the paging message is SP
It may be present on one or more channels, including some of the ACH or equivalent control channels. For example, the paging message may include a pointer message for the SPACH control channel and a more detailed information packet for the indicated channel. Therefore, as used herein, the term paging message refers to any transmission information that a mobile terminal automatically searches to determine whether the mobile terminal has the incoming call and the nature of the incoming call. including.

Further, the above was made in terms of the group call server modifying the paging message to include an indicator of one or more group call features. In the main embodiment, the group call server appends a display flag character to the calling field of the paging message. However, the addition of characters
Not necessary. Instead, the present invention encodes an existing message to include additional information by encoding the current message, for example by superimposing another message on the current message using different encoding mechanisms or the like. Equivalent methods of increasing can be included. Thus, what is simply needed is that the paging message be modified from what it would otherwise take, and the modification is to display one or more characteristics of the group call.
