Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication terminal such as an automobile / mobile phone system or a cordless phone system, and more particularly to an incoming call operation technique in the mobile communication terminal.

[0002]

2. Description of the Related Art In recent years, mobile communication systems such as car telephones, mobile telephone systems, cordless telephone systems, etc. have become easier to use due to the development of networks and the reduction in size, weight and cost of mobile telephones. Yes, there are signs that it will spread rapidly in the future.

When a mobile communication system is used, a user can carry out communication "anytime, anywhere, with anyone" simply by carrying a compact terminal, and it is very convenient to receive an incoming call at any place such as an outside place. This is well known. Among them, the personal handyphone system (PHS) cannot be used while moving at high speed in a car, etc., but it can be used as a cordless telephone handset at home, and as a mobile telephone via a public network in urban areas. The feature is that you can talk.

In constructing a mobile communication system, transmitting a strong radio wave from an antenna of a base station over a wide range is not a good idea from the viewpoint of effective use of the radio wave. Therefore, generally, the service area is divided into small zones called cells (for example, a diameter of several kilometers), and base stations are arranged in these wireless zones, respectively, and the number between the base stations and mobile communication terminals is increased. A cellular system is used in which communication is performed by transmitting radio waves of 100 mW to several W.

In order to realize such a cellular system, when a mobile communication terminal moves from one wireless zone to another wireless zone, it is necessary to have a function of tracking this and notifying an incoming call. Therefore, the location registration procedure is specified.

In this location registration procedure, the location zone of the mobile communication terminal that has subscribed to the service is set for each mobile communication terminal in the mobile communication terminal management device (hereinafter referred to as mobile device management device) of the mobile communication network. It is for registering and managing a zone zone (a wireless zone that currently exists). For example, when the mobile communication terminal receives the broadcast information periodically transmitted from each base station, and the area code included in the broadcast information is different from the area code until then, the mobile communication terminal number (hereinafter, A location registration request including a mobile station number) is transmitted to the mobile station management device of the mobile communication network to register / update the latest visited zone of the mobile communication terminal. As a result, tracking of the mobile communication terminal is realized.

When notifying the incoming call to a certain mobile communication terminal, the exchange of the mobile communication network inquires the above-mentioned mobile station management device about the zone in which the mobile communication terminal is located. It is possible to specify and notify the incoming call from the base station of the zone.

On the other hand, in the wired fixed network, a personal communication system is being studied as one of the advanced network services in the intelligent network (IN). In this personal communication system, (1) each individual is given a single personal number, and each individual, including homes, offices, and other locations, registers the personal number on the network with a telephone familiar to him / herself. , (2) The network manages the subscriber number of the telephone by linking the personal number to the telephone number, and (3) the network automatically transfers an outgoing call using the personal number to the telephone of the additional person number. By performing the processing, a tracking connection corresponding to the movement of the individual, a so-called "chase call" is realized even in the fixed network.

[0009]

However, the conventional mobile communication system of this type has the following problems to be solved. In other words, the tracking connection function, which is indispensable for mobile communication networks, provides users with the convenience of being able to communicate with "anytime, anywhere, with anyone", while depending on the user's position, "anytime, anywhere, with anyone.""I also have the hassle of being chased.

For example, when the user uses the mobile phone for business use, the power can be turned on only during business hours and turned off when the business is over to reject incoming calls after business hours. . However, in consideration of the case where the user also uses one mobile phone for other purposes such as private use, it is difficult to turn it on and off depending on the place and time. In addition, it is impossible to separate call charges according to the purpose of use such as business and private use.

On the other hand, considering the above-mentioned inconvenience from the standpoint of the caller, when the other party's mobile phone encounters a power-off due to circumstances such as location and time, unlike a fixed-line phone, it will be different from a nearby agent. Even I couldn't make a call, and I couldn't contact him.

These inconveniences can be solved by carrying a plurality of telephones according to the purpose of use and using them properly according to the purpose of use. It is annoying to have to carry multiple phones and use them properly.

Further, although it can be solved by using an additional service of the mobile communication network, for example, an answering machine service, not only large-scale equipment needs to be installed in the network, but also the user can use these services. You are forced to pay the fee.

Therefore, a first object of the present invention is to allow a plurality of mobile unit numbers to be used by one unit, which are selectively used according to the purpose of use, and to store / store a plurality of stored mobile unit numbers as desired by the user. Can be allowed to be deleted,
Accordingly, it is an object of the present invention to provide a mobile communication terminal which can receive only an incoming call of a mobile device number desired by a user at a place, a time, etc., and can also make an outgoing call at a mobile device number desired by the user.

A second object of the present invention is to notify, when a user registers / deletes a mobile unit number, a communication terminal which has been set in advance, so that the communication terminal can act on behalf of the mobile communication terminal / stop acting on behalf of the mobile communication terminal. As a result, the receiving user can receive only the desired mobile phone number at any place, time, etc. without having to newly install additional service equipment on the network, and delete it. It is to provide a mobile communication terminal that realizes economical communication by the proxy terminal responding to the incoming call of the set mobile unit number.

[0016]

In order to solve the above-mentioned first problem, a first invention is to provide a plurality of mobile communication terminals having a position registration procedure for registering a visited zone in a mobile communication network. The mobile unit number can be registered / deleted, and the control unit can register / delete the mobile unit number in the storage unit when a condition is satisfied corresponding to a predetermined setting. Each time the mobile unit number is registered in the storage means by the means, the location registration procedure is activated for the network, and thereafter, the mobile communication terminal receives an incoming call of any of the mobile unit numbers registered in the storage means. When waiting and making a call, the user can select any mobile station number registered in the storage means to make a call.

On the other hand, in order to solve the above-mentioned second problem, a second invention is a mobile communication terminal having a location registration procedure for registering a visited zone in a mobile communication network, wherein a plurality of mobile device numbers are provided. Storage means capable of registering / deleting a mobile station number, control means for registering / deleting a mobile station number in / from the storage means when a condition is satisfied for a predetermined setting, and registration of a mobile station number in the mobile communication network / Each time the mobile unit number is registered / deleted in the storage unit by the control unit, the mobile unit number is registered / deleted in a previously designated mobile communication terminal. The mobile communication terminal that has received the notification of registration activates the location registration of the notified mobile unit number on the network, and thereafter, the mobile communication terminal waits for an incoming call of the notified mobile unit number on behalf of the mobile communication terminal. And notification of deletion If received, in which as hereinafter to stop listening for incoming received a notification mobile number.

In the first and second aspects of the invention, the mobile device number is set on condition that any one of a predetermined user operation, a preset time, a preset visited zone, or a combination thereof is used. It is characterized in that the mobile unit number is registered / deleted from the storage means.

Further, according to the second aspect of the present invention, when notifying a mobile communication terminal of registration / deletion notification of a mobile unit number, a predetermined authentication procedure is performed at the mobile communication terminal, and the authentication is successful. Only at that time, the mobile communication terminal that has received the notification is in a standby state for acting as an incoming call.

As a result, according to the first aspect of the present invention, a plurality of mobile station numbers are stored in the storage means capable of registration / deletion when a user operation or a predetermined condition such as a preset time and place is satisfied. The mobile number is registered / deleted. When a certain mobile unit number is registered, the location registration procedure for the mobile unit number is activated, so that the mobile unit can thereafter wait for an incoming call of the mobile unit number. Further, when a certain mobile station number is deleted, the incoming call of the deleted mobile station number is ignored thereafter, so that the user can receive only the incoming call of the desired mobile station number.

On the other hand, according to the second invention, a user operation,
Alternatively, when a predetermined mobile station number is registered / deleted in the storage means capable of registering / deleting a plurality of mobile station numbers when predetermined conditions such as preset time and place are satisfied, mobile communication specified in advance is performed. A mobile unit number registration / deletion request is transmitted to the terminal. After that, when the mobile communication terminal that has received this registration / deletion request is notified of registration of a certain mobile unit number, the location registration procedure for that mobile unit number is activated, and this mobile unit will thereafter Wait for incoming number. If a mobile number is notified to be deleted,
Since the incoming call of the deleted mobile number is ignored, the first user receives only the incoming call of the desired mobile number, and the incoming mobile phone numbers other than that can be answered by the substitute mobile communication terminal. Become.

With this, the user can receive only the desired incoming call anytime and anywhere without carrying a plurality of mobile communication terminals, and the unwanted call is answered by the proxy terminal, so that the caller can be called. You will never be out of contact. Also, in the network, it is not necessary to install large equipment for providing additional services such as transfer and answering machine, and economical mobile communication can be realized.

[0023]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a mobile communication terminal to which the present invention is applied will be described below in detail with reference to the accompanying drawings.
First, the network configuration of the mobile communication network will be described with reference to FIG. The network shown in FIG. 1 is configured to be able to provide mobile communication services together by using the connection / switching function of a fixed communication network based on ISDN technology (Integrated Services Digital Network).

In FIG. 1, the ISDN 1 is mainly composed of an exchange 11 which performs a call control process between a calling terminal and a called terminal. The line interfaces 121 to 1 of this exchange 11
2n, 12n + 1 to 12m, and 12m + 1 are of ISDN basic interface specifications, and the ISDN-compatible fixed telephones TEL1 to TELm are connected to the line interfaces 12n + 1 to 12m.

The line interface 12m + 1 is connected to the mobile unit management device 2 for managing the zones S1 to Sn of the mobile communication terminal MS, and the line interface 1
Base stations BS-1 to BS-n for providing mobile communication services in the respective zones S1 to Sn are connected to 21 to 12n. From the exchange 11, the mobile unit management apparatus 2 and the base stations BS-a to BS-n are connected to the fixed telephones TEL1 to TEL.
Like ELm, it is configured to be handled as one subscriber terminal.

In the present embodiment, a case will be described in which a basic ISDN interface is applied to the above-mentioned line interfaces 121 to 12m + 1. The ISDN basic interface goes up according to the TTC standard (Telephone and Telephone Technical Committee) standard JT-G961 by a ping-pong transmission method using a two-wire metallic cable.
Two information (B) channels B1 and B2 each having a transmission capacity of 64 Kb / s in the downlink and a signal (D) channel having a transmission capacity of 16 Kb / s are multiplexed and transmitted (2B + D).

The above-mentioned D channel is a B channel used for communication by performing a call control signal procedure defined by TTC standards JT-Q921 and JT-Q931 between the exchange 11 and the terminal MS when the terminal MS makes and receives a call. Assign Between the terminals MS that have moved during communication by this call control procedure, arbitrary terminal-to-terminal communication information such as voice and data can be transferred on the B1 or B2 channel allocated by the exchange 11.

Next, a mobile communication service via the exchange 11 will be described. In FIG. 1, the base stations BS-1 to BS-n are connected to the line interfaces 121 to 12n of the exchange 11 via lines, respectively. From the viewpoint of the exchange 11, each base station BS is treated as one of ISDN terminals similar to a normal telephone, and is installed at appropriate intervals in an area (zone) that provides mobile communication services. .

For example, each base station BS uses a radio frequency band of 800 MHz by complying with RCR STD 127, which is a standard for "Digital Car Telephone System" established by the Radio System Development Center (RCR). The carrier frequency is 50 KHz,
TDMA (Time Division Multip
iex) system to communicate with the mobile communication terminal MS. The transmission output of the mobile communication terminal MS is 300 mW to 3.0 W, and one zone is several tens of K in terms of the distance from the base station BS.
Cover m squares.

In the present embodiment, as shown in FIG. 1, the base stations BS-1 to BS-n are installed in the zones S1 to Sn, respectively, and are located within the reachable area of the radio wave indicated by the broken line. The communication service of the mobile communication terminal MS is provided.

Between each base station BS and the mobile communication terminal MS located in the area, a radio access method based on the TDMA method is used to inform the mobile communication terminal MS from the base station BS of the area information. Broadcast channel (BC
CH), a common control channel (CCCH) for transferring call control signals for incoming and outgoing calls, and an information channel (TCH) for transferring end-to-end information such as voice and data are multiplexed and transferred.

An area number having a single value is given in advance to each base station BS, and B of each base station BS is assigned.
On the CCH, the notification information message including the area number information element of the zone having the structure shown in FIG. 2A is periodically notified to the mobile communication terminal MS.

FIG. 3 shows an example of the location registration procedure. First,
Each base station BS receives the broadcast information message from the mobile station management device 2 through the D channel (DCH) of the ISDN basic interface, and transmits it to the corresponding area (zone) by BCCH.

Each mobile communication terminal MS periodically, in the standby state in which the power is turned on, the base station BS in the corresponding zone periodically.
-1 receives the "broadcast information" message from the BCCH transmitted from -1. Then, the area number obtained by receiving the notification information is stored, and the stored area number is compared with the area number of the currently received "report information" message.

At this time, when the previously stored area number is different from the latest area number, it is determined that the own terminal MS has moved to the new zone, and the base station BS-1 in the new zone is sent to the base station BS-1 shown in FIG. The "location registration request" message including the own terminal number information element is transmitted by CCCH in the structure as shown in (b).

The "location registration request" message transmitted from the mobile communication terminal MS on the CCCH and containing the mobile station number is transferred to the exchange 11 after being transferred to the D channel at the base station BS-1 in the corresponding zone. . Exchange 11
Then, when a signal message related to the location registration procedure is received, the signal message is designed to be transferred via the D channel to the mobile station management device 2 that manages the location of the mobile communication terminal MS. ing.

In the mobile unit management device 2, the mobile unit numbers included in the "location registration request" message received from each base station BS are sequentially stored in the internal mobile communication terminal location information table, and the "location registration acceptance" message is sent. Transmit to each base station BS on the D channel. At this time, the information is transmitted from the base station BS-1 via the CCCH of the radio interface to the mobile communication terminal MS that has requested the location registration. Mobile communication terminal MS
Then, the "location registration acceptance" message is received from the CCCH, and the network number information is extracted from the message and stored.

By the above processing, the initial setting is completed and a standby state is set. In this standby state, the base station BS
Receives the "notification information" message transmitted via the BCCH, extracts the area number, compares it with the previously stored area number, and confirms the area of the terminal itself.

Here, for example, when making a roaming request, a "location registration request" message including the own terminal number information element is transmitted by CCCH due to a change in network number. The “location registration request” message including the mobile station number is transferred to the mobile station management device 2 via the exchange 11 by being transferred to the D channel at the base station BS-n in the corresponding zone.

In the mobile unit management device 2, as described above,
The mobile device number included in the "location registration request" message is stored in the above table, and the "location registration acceptance" message is sent to D
Send back on the channel to the base station BS-n.

The base station BS-n transmits a "location registration acceptance" message to the mobile communication terminal MS that has requested the location registration via the CCCH of the radio interface. The mobile communication terminal MS receives the "location registration acceptance" message from the CCCH, extracts the area number information from the message, and stores it. After that, the same operation is repeated.

FIG. 4 shows an example of the above-mentioned mobile communication terminal location information table. As a result of the location registration procedure being sequentially processed between each mobile communication terminal MS and the mobile device management apparatus 2, the mobile communication terminal location information table shows each mobile communication terminal (number) subscribed to the mobile communication service. The area code in which each mobile communication terminal MS is located is stored, and each time the mobile communication terminal MS registers its location, the area code is sequentially updated to the latest area code.

FIG. 5 shows a sequence of standard call control signal procedures for transmission and reception between the exchange 11 and the mobile communication terminal MS via the above-mentioned base stations BS. In the following description, the mobile communication terminal on the calling side will be referred to as the calling terminal MS.
(T), the mobile communication terminal on the called side is shown as a calling terminal MS (R).

In FIG. 5, the transmission terminal MS (T) includes information elements such as transmission capability, called number and calling number.
When a "call setup" message having a structure as shown in (c) is sent to the base station BS on the air interface, the base station B
The S sends the "call setup" message received via the ISDN 1 to the exchange 11.

On the other hand, the exchange 11 sends a "call setting acceptance" message notifying the B channel used for communication to the base station BS, and the base station BS sends the message via the air interface to the calling terminal MS (T). ) To.
Since messages are transmitted and received equivalently on the ISDN and the air interface, the following description will be simplified.

The exchange 11 starts the incoming call connection processing to the line corresponding to the called number included in the above-mentioned "call setting" message. In the incoming call processing, the exchange 11 is referred to by referring to the visited zone for each mobile communication terminal stored in the mobile device management apparatus 2.
It is started by transmitting a "paging" message including the mobile station number for making an incoming call from the mobile station to the base station BS corresponding to the zone.

Actually, this "paging" message is transmitted from not only the base station BS where the receiving terminal MS (R) has registered its location but also the peripheral base stations BS at the same time, but it is not essential here, so its explanation is given. Is omitted.

Now, the "paging" message is transmitted from the base station BS for a predetermined time (for example, several seconds), but the terminating terminal MS (R) located in the zone of the base station BS is in the standby state and periodically. Check for receipt of "paging" message. If the message is received, check whether the mobile device number included in the message matches the own station. If they do not match, the standby process is continued, but if they match, the incoming call response process starts.

Here, when the mobile station number matches with its own station, the receiving terminal MS (R) first measures the reception level of the radio wave from the base station BS, and measures this together with the mobile station number in the "incoming radio state". It is transmitted to the exchange 11 as a "report" message. Upon receiving this, the exchange 11 confirms the mobile station number and the reception level, adjusts the transmission power as appropriate, and transmits an incoming "call setting" message to the receiving terminal MS (R).

Upon receiving this "call setting" message, the receiving terminal MS (R) compares whether the transfer capability matches the communication function of the terminal, and if they match, it notifies that the incoming call has been accepted. Switch message 1
Send to 1. The transmission capability of the telephone is to compare whether the partner terminal and the own terminal have voice communication functions with each other.

When the call at the terminating terminal MS (R) is started, a "call" is made from the exchange 11 to the originating terminal MS (T).
When the signal is transmitted and the receiving terminal MS (R) further performs a receiving operation, a “response” message is transmitted to the transmitting terminal MS (T) via the exchange 11. This enables communication between terminals such as voice, data and images using the B channel.

Next, when the communication on the B channel is completed and the calling terminal MS (T) transmits a "disconnect" signal, "release" is issued.
A signal is transmitted from the exchange 11 to the originating terminal MS (T),
This communication ends when the transmitting terminal MS (T) receives this and transmits a "release complete" signal. On the other hand, the receiving terminal MS (R) side disconnects / releases the B channel in use by receiving the “disconnect” message from the exchange 11 in response to the disconnection on the transmitting terminal MS (T) side. .

Here, in the "call setting" message shown in FIG. 2 (c), in addition to the transfer capability, the channel identifier, the called number and the calling number required for the exchange 11 to connect the calling and called terminals, It is characterized in that it can include user-user information capable of transmitting arbitrary terminal-to-terminal information between terminals, and the mobile communication terminal MS according to the present invention uses this to notify the registration / deletion request of the mobile unit number.

Next, the configuration when the present invention is applied to a mobile phone will be described. FIG. 6 is a schematic configuration diagram of a mobile phone to which the present invention is applied. As shown in FIG. 6, a mobile phone to which the present invention is applied has a microcomputer (CPU) 21 that performs system control of the entire apparatus as a core,
A program memory (PMEM) 23 including a read-only memory (ROM) in which a control program is stored on the system bus 22 and a random access memory (RAM) for working, and a mobile unit number of the mobile phone are registered / deleted. A possible mobile unit number memory 24, a call origination / termination operation unit 25, and a voice codec 27 for digitizing and compressing / decompressing voice signals from the handset 26.

Of these, the PMEM 23 has an operation unit control function of manually inputting key data through the operation unit 25 and outputting display information to the LED and LCD when the user makes an incoming / outgoing operation, and an air interface 28. A program for controlling a signal control function for exchanging the location registration procedure shown in FIG. 3 and the outgoing / incoming message procedure shown in FIG. 5 with the exchange 11 of the mobile communication network via the base station is stored.

The PMEM 23 further has a mobile unit number management function (first invention) of registering / deleting the mobile unit number in / from the mobile unit number memory 24, and in addition to this mobile unit number management function, registration / deletion thereof. A program for the registration / deletion request transmission / reception function (second invention) that controls the transmission / reception of requests is also stored.

Further, as shown in FIG. 7, the mobile unit number memory 24 has memory areas 241 and 242 for fixedly storing two mobile unit numbers and a rewritable memory area 2.
It is composed of 43 and 244. Fixed memory area 24
In this example, up to two subscriber numbers 1 and 242 can be stored when a mobile communication terminal is contracted with a business operator, and cannot be rewritten thereafter. These two mobile unit numbers are secured in the RAM area of the PMEM 23, and the mobile unit number stored in the mobile unit number memory 24 in the current state is used to manage the mobile unit number flag controlled by the mobile unit number management function. To be done.

On the other hand, the rewritable memory area 243,
244 is not used for the processing operation of the first embodiment described below, but in the processing operation of the second embodiment, when the registration request from the remote mobile communication terminal is received, the remote mobile communication is performed. It serves as a mobile unit number memory for writing the mobile unit number received from the terminal.

Next, the processing operation in the first embodiment will be described with reference to FIGS. 8 and 9. FIG. 8 is a flowchart showing a schematic processing flow of the control program of the mobile communication terminal in the first embodiment, and FIG. 9 is a diagram showing its operation sequence.

First, when the mobile communication terminal MS is powered on, the initialization processing stored in the ROM of the PMEM 23 is started to initialize the operation section 25, the voice codec 27, and the air interface 28 together with the RAM area. The state is set (step ST1). Here, when the RAM area is initialized, two mobile unit number flags corresponding to the two mobile unit numbers stored in the fixed memory areas 241 and 242 of the mobile unit number memory 24 are set, and the mobile unit number N is set.
o. 1, No. Set 2 to a valid state.

Next, when the location registration procedure stored in the ROM of the PMEM 23 is activated, the mobile station number No. is referred to by referring to the mobile station number flag. 1 and No. 1 Two location registration request messages of 2 are sent from the air interface 28,
It is sent to the exchange 11 of the mobile communication network via the base station BS (step ST2). This sequence is shown in FIG.

In FIG. 8, the mobile communication terminal MS-A corresponds to this, and the exchange 11 responds to the mobile communication terminal MS-A with a location registration acceptance message. From the viewpoint of the exchange 11, these two location registration requests are related to the conventional mobile communication terminal 2
It is exactly the same as receiving the location registration request message from the platform, and no special control is required. In this way, the exchange 11 has the mobile unit number No. 1, No. Two mobile communication terminals M
The mobile station management device 2 indicates that S is located in the base station BS.
Stored in the position information table of.

When the mobile communication terminal MS-A completes the two location registration procedures, the mobile unit number No. 1, No. The mobile station enters into a standby state in which it is possible to make and receive calls with two mobile unit numbers 2 (step ST3). In the standby state, PMEM23
The mobile communication terminal MS-A periodically receives the notification information from the base station BS (step ST

5), the process of receiving a paging message indicating an incoming call from the base station BS (step ST6) and the process of registering / deleting a mobile unit number in the operation unit 25 (step ST7) are performed in parallel in a time division manner. .

In receiving the notification information in step ST4,
Confirm whether or not the existing zone has moved (step ST8),
If the visited zone has moved, the location registration procedure of step ST2 is restarted. These are exactly the same as the operations described in FIG.

In the calling process of step ST5, when it is detected that the dialing operation of the other party's number is completed by the operation unit 25, the calling procedure of the sequence shown in FIG. 5 is started (step ST9).

When the paging message is received from the base station BS in the paging reception process of step ST6, it is confirmed whether or not the own mobile station number is included therein (step ST10). At this time, the mobile station number No. stored in the mobile station number memory 24 is stored. Of the numbers 1 and 2, the mobile unit number flag set is compared with the mobile unit number included in the paging message, and if they match, the incoming procedure shown in FIG. 5 is activated (step ST1).
1). If they do not match, the process returns to step ST3,
It goes into a standby state.

When both line connections are established by the above calling and receiving procedures, communication is in progress (step ST1).
2). At the end of communication, the disconnection procedure is executed (step ST
13) The standby state is entered (step ST14).

In addition, in the registration / deletion process of step ST7, when the registration / deletion operation of the mobile unit number is performed by the operation of the function key of the operation unit 25, the mobile unit corresponding to the mobile unit number designated by the user by this operation. The number flag is set in the case of the registration operation and reset in the case of the deletion operation (step ST15). In the case of resetting, the process returns to step ST3 and enters the standby state. In the case of the set, the location registration procedure is executed for the base station BS (step ST16), and the standby state is set (step ST14).

For example, as shown in FIG. When the deletion operation of the mobile station number No. 1 is performed.
The mobile unit number flag of No. 1 is reset, and in this state the mobile unit number No. Paging message containing 1 to base station B
Even if received from S, the operation of ignoring the incoming call is performed. on the other hand,
In this state, the mobile device number No. When the paging message including 2 is received from the base station BS, the normal incoming call acceptance operation is performed.

In this way, the mobile communication terminal MS having two mobile unit numbers can use two mobile unit numbers at the same time or one of them depending on the user's registration / deletion of the mobile unit number. It will be possible. Therefore, the user can easily use one mobile communication terminal MS depending on time, for example, for business use / private use.

Next, the processing operation in the second embodiment will be described with reference to FIGS. 10 and 11. FIG. 10 is a flowchart showing a schematic processing flow of the control program of the mobile communication terminal MS in the second embodiment, and FIG. 11 is a diagram showing its operation sequence.
