DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments according to the present invention will be described below in detail with reference to the accompanying drawings. Note that the same reference numerals indicate the same or corresponding parts throughout the drawings. FIG. 2 is a diagram showing the configuration of the message mail service system according to the embodiment. In the figure, 1 is a fixed telephone such as a push phone, 2 is a subscriber line exchange (EO) accommodating the fixed telephone 1, 3 is a fixed network and others. A public network connected to a mobile network, 4 is a mobile switching center (MSC), 4
Numeral 1 is the call path switch, numeral 42 is a control unit, numeral 43 is a message control unit, numeral 44 is a voice storage unit, numeral 45 is a timer management unit, numeral 5 is a home location register (HLR), numeral 6 is a radio base station (BS), and numeral 7 is The mobile device (MS) 71 is its main body, 7
2 is a telephone, 73 is a control unit, 73 ₁ is a memory (LM),
74 is a transmission / reception unit (T / R), 75 is a power supply unit of the mobile device 7,
76 is a battery, 77 is an open / close switch, 78 is a timer control unit (TC) for turning on / off the open / close switch 77 at a predetermined cycle, and 79 is an operation switch.

[0013] In the mobile device 7, the memory 73 ₁ holds a regional identification code received the location registration in advance by the control unit 73, the control unit 73 is notified by the region identification code and then the reception control channel of the memory 73 ₁ If they do not match with each other, a new location registration request is issued to the wireless base station 6. And the memory 7
3 ₁ region identification code is reset by the control unit 73 by signal area identification code in the power OFF or control unit 73 of the mobile device 7 is not received for a predetermined time or more.

Therefore, not only when the mobile station 7 moves to a wireless service area in another area, but also in other cases,
For example, when the power of the mobile device 7 is turned on from off, or when the mobile device 7 once goes out of the wireless service area and returns to the service area again, the control unit 73 sets the radio base station in each case. 6, a new location registration request is generated. As a result, the chances of a location registration request from the mobile unit 7 increase, and as a result, the chances that a message indicating that a message has been sent from the mobile exchange 4 to the mobile unit 7 will increase as will be described later.

By the way, the subscriber B turns off the power supply of the mobile unit 7.
If you leave it as FF, you will not get the above benefits. Therefore, the mobile device 7 of the present embodiment has three power modes for turning on and off the power and turning the power of the mobile device 7 on and off at predetermined intervals. You can choose one. For example, if the contacts d and b of the operation switch 79 are connected, the power is basically turned off for a relatively long time, but the power is turned on intermittently, which causes a position registration request to be generated. Then, a message indicating that there is a message can be received along with the position registration response signal at that time. Alternatively, the operation switch 79
When the contacts d and b are connected, the power is basically turned on for a relatively long time, but the power is turned off intermittently.
, And a position registration request is generated by turning on the power thereafter, and a notification that a message is present can be received along with the position registration response signal at that time. However, in the latter case, the timer control unit 78 is controlled under the control of the control unit 73, and is controlled so that the power is not turned off while the mobile device 7 is operating (during a call or the like).

FIG. 3 is a diagram for explaining information relating to the message mail service of the embodiment. FIG. 3A shows message message storage information, and FIG. 3B shows a home location register (hereinafter referred to as HLR). It is a figure explaining registration information on presence or absence of 5) message. In FIG. 3A, the message control unit 43
Records the first voice message MSG "Call me again" addressed to the called party A in the free address ADD = 0 of the voice storage section 44, and the address information ADD = Write 0. Next, the message control unit 43 sends the first voice message MSG addressed to the called party B.
When “b, call me” is recorded in the vacant address ADD = 1 of the voice storage unit 44, the address information ADD = 1 is written at the beginning of the column of the called party B in the table for managing this. Hereinafter, in the same manner, each time a voice message arrives, the voice message is recorded in an empty address of the voice storage unit 44,
The address information ADD is linked for each receiver. Then, an end mark E is written at the end of each link.

In FIG. 3B, at the location referred to by the subscriber number (telephone number) A of the called party A in the HLR 5, the address information ADD = of the message message recorded by the calling parties a to c respectively. 0, 2, and 4 are stored. If necessary, the sender a can specify the urgency and the expiration date of the message by the PB signal in the exchange of the voice signal with the message controller 43. If there is no designation, default information D is recorded, and a predetermined urgency and expiration date are applied. The same applies to the called party B.

Although not shown, the HLR 5 also registers and manages the location of each mobile device owned by each subscriber and various service information. For example, the HLR 5 is referred to by the subscriber number A of the subscriber A. The storage area stores a subscriber authentication key, a mobile station number, a roaming (location registration) state, a roaming destination network, a roaming number, an answering service flag for holding a start / stop state of the answering service, and the like. I have.

FIG. 4 is a flowchart of the incoming call processing of the embodiment. For example, from the fixed telephone 1 (caller c) to the mobile device 7
When (callee B) is called, the call is switched to the local exchange 2
And is relayed to the mobile switching center 4 via the public network 3. Upon receiving the incoming call request from the caller c, the control unit 42 of the mobile switching center 4 requests the HLR 5 for incoming call and message presence / absence information. On the other hand, the HLR 5 determines whether or not the called party B is a connectable subscriber, whether or not the mobile device 7 is registered in the area, and whether or not there is a message message addressed to the called party B. And the response information of the incoming / outgoing message or the like.

When the called party B is connected, the control unit 42
Checks whether the mobile device 7 is in the answering machine service (or the location is not registered), and connects the message control unit 43 to the fixed telephone 1 when the answering machine service is in effect. If the answering machine is not in the answering machine service, the control unit 42 performs a predetermined line connection process, makes a general call to the mobile station 7 via the radio base station 6, and makes a ring back tone RBT to the fixed telephone 1. Is sent. Then, at this time, if the information indicating that the message is addressed to the called party B has been received from the HLR 5, the control unit 42 places the information indicating that the message is present on the control channel of the general call to the mobile device 7 and moves. Notify machine 7.

On the other hand, in the mobile unit 7, if the power is turned on.
If the mobile terminal is located in the wireless service area, the information indicating that there is a message is received together with the general call, a response to the general call is returned, and the information indicating that the message is present is displayed on a display unit (not shown). Alternatively, the message B may be notified to the subscriber B of the mobile device 7 by sound / vibration or the like. Thus, when the call to the called party B is received, information indicating that there is a message addressed to the called party B arrives.

However, when the mobile station 7 is in a power-off state or is moving out of the wireless service area, no response to the paging is returned. The control unit 42 continues to determine whether or not there is a response from the mobile device 7. If there is no response to the paging, the message control unit 43 is connected to the fixed telephone 1 also in this case. A communication path is formed between the communication control unit 43 and the message control unit 43.

The message control unit 43 transmits a voice mail message "Now you are away" to notify whether or not to continue receiving the message mail service. The caller c listens to this, understands that he is away, and if there is a message message, PB
The use of this service is notified by a signal. Thereafter, the caller c transmits a voice message “c, call me” by voice, and the voice message control unit 43 stores the voice message in the voice storage unit 44. If necessary, the message controller 43 transmits "Please input a password for referencing the message", and the caller c inputs the password c by a PB signal. Further, if necessary, the message control unit 43 transmits "Please input the urgency and expiration date of the message transmission", and the caller c transmits the urgency of the message transmission by the PB signal (for example, the maximum urgency). 1) and an expiration date (for example, 1 day) are input.

When the business is completed, the caller c hooks up the fixed telephone 1. As a result, the control unit 42 detects the call disconnection on the fixed telephone 1 side, and thereby restores the communication line. Next, the control unit 42 gives the recording address ADD = 3 of the message message from the message control unit 43 and the sender c.
, The urgency of the message transmission = 1, and its expiration date = 1 day (however, converted to time information such as the date), and these are stored in the storage area of the HLR 5 for the callee B. . Thus, the message presence information about the called party B is stored.

Preferably, a timer management unit 45 for generating a timer signal at a predetermined cycle is provided. Timer management unit 4
5 manages time information such as year, month, day, hour and minute in real time, and generates a timer signal, for example, every 5 minutes or 10 minutes. In FIG. 4, when a timer signal is generated, an interrupt is generated in the control unit 42 based on the timer signal. Thereby, the control unit 42 checks the information on the presence or absence of the message of the HLR5,
If there is a message, the mobile station (for example, 7) is paged at the same time to notify the information of the message. However, in this case, the general paging is not a general paging for incoming call connection, but may simply be carried on a general paging control channel to notify only the information of the presence of a message. Thus, the mobile device 7 can appropriately receive the information indicating that there is a message without the incoming call and the location registration and calling described later.

In this way, the called party B who has received the message presence information introduces the message message by operating a special number on the mobile exchange 4. After obtaining the authentication B of the callee B, the control unit 42 refers to the column of the callee B of the HLR 5 and, if there is a message message, connects the message control unit 43 to the line of the callee B and stores the voice. A series of message messages in the section 44 are transmitted.

At this time, the message message whose expiration date has already passed has been deleted by the control unit 42 by periodically searching the HLR 5. Also, the caller c can introduce a message message registered by himself / herself by operating a special number on the mobile switching center 4. in this case,
After obtaining the authentication c from the sender c, the controller 42 refers to, for example, the column of the called party B of the HLR 5 according to the designation of the sender c, and if there is a message message registered by the sender c there, The message control unit 43 is connected to the line of the caller c, and the message stored in the voice storage unit 44 is transmitted. Thereafter, the sender c can delete unnecessary message messages by sending a predetermined PB signal.

FIG. 5 is a flowchart of the location registration process according to the embodiment. When the power of the mobile device 7 is turned on within the service area, or when the mobile device 7 returns to the wireless service area from outside the service area, the mobile device 7 detects a change in the location registration area, and sends a location registration request to the mobile exchange 4. Upon receiving the location registration request from the mobile unit 7, the control unit 42 of the mobile switching center 4 requests the HLR 5 for location registration for the subscriber B and information on the presence or absence of a message. On the other hand, HLR5
Sends back the location registration information including the authentication key of the subscriber B and whether or not there is a message message addressed to the called party B, and response information on the presence or absence of the message.

Upon receipt of this, the control unit 42 authenticates the subscriber B using the authentication key. If the authentication result is acceptable, the control unit 42 sends a location registration acceptance to the mobile device 7.
Then, at this time, if information indicating that there is a message addressed to the called party B has arrived from the HLR 5, the control unit 42 puts the information indicating that there is a message on a control channel for accepting location registration for the mobile device 7, for example. Notify the mobile device 7. HLR5
Sends a location registration instruction. Thus, the information indicating that there is a message addressed to the called party B arrives upon the location registration request from the subscriber B.

FIG. 6 is a flowchart of the calling process according to the embodiment. When the subscriber B makes a dial call, the control unit 42 of the mobile switching center 4 requests the HLR 5 for information on the call origination and presence / absence of a message about the subscriber B. HL
R5 returns response information indicating whether or not there is an authentication key of subscriber B and whether or not there is a message message addressed to called party B, and whether or not there is a message.

Upon receipt of this, the control unit 42 authenticates the subscriber B using the authentication key, and if the authentication result is acceptable, the control unit 42 sends a control signal for establishing a communication channel to the mobile device 7. . Then, at this time, if information indicating that there is a message addressed to the called party B has arrived from the HLR 5, the control unit 42 puts the information indicating that there is a message on a control channel for establishing a communication channel for the mobile device 7, for example. Notify the mobile device 7. Thus, the information indicating that there is a message addressed to the called party B arrives upon the transmission request from the subscriber B.

Further, the control unit 42 checks the called number (dial number) in the outgoing signal (SETUP) from the mobile unit 7, and sends an address setting signal IAM to the corresponding receiving side exchange (not shown) to call. Make settings. On the other hand, the receiving side exchange responds with the address completion signal ACM, calls the called party, and returns the called party response signal ANM when the called party hooks off the receiver. Thereby, the mobile switching center 4 sends a connection signal CONN to the mobile station 7, and
A communication path is formed between the sender B and the called party.

In the above embodiment, a call between a fixed telephone and a mobile device has been described as an example. However, the present invention can be applied to a call between a mobile device and a mobile device. In the above embodiment, the voice storage unit 44 and the HLR 5 have been described as separate means. However, for example, a voice message is converted into a digital signal by CODEC or the like and stored in the HLR 5, and this is read out from the HLR 5 and converted into a voice message. In this case, the voice storage unit 44 may be provided in the HLR 5.

[0034]

As described above, the mobile communication system according to the present invention is described.
Since the system and the mobile device are configured as described above, the message message left by the caller can be quickly transmitted to the callee.
