Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile communication network system, and more particularly, to a mobile communication network system having a reception-only mode that is not transmitted from a mobile device side.
[0002]
[Prior art]
In a conventional mobile communication network system, a mobile device autonomously transmits a response to a call or a location registration when a call is generated or a location is registered. A case of a call to a mobile device will be described with reference to FIG.
[0003]
In FIG. 1, a telephone is connected to a mobile device 102 from a telephone set 144 connected to another system. In this case, the telephone number of the mobile device 102 is connected to the mobile communication network via the public line network 142. The gateway switching node 124, which is a connection node with the public network in the mobile communication network, indicates the subscriber status of the mobile device (for example, whether it is in a connectable state), the current registration position, etc., in a home memory (HLR) 134. Contact Then, the mobile devices 102 are called all at once from the base station 112 or the like in the location registration area. When the mobile station 102 responds to the simultaneous call, the mobile station 102 performs line setting and connection to the base station 112 that has received the response and the upper subscriber switching node. Thus, the telephone 144 and the mobile device can make a call.
[0004]
In this way, the mobile device performs transmission when making a response without transmitting it. Therefore, when the power is not turned off, transmission may be performed without intention. For example, in a hospital or the like, the radio wave emitted from the mobile device may affect the device.
[0005]
[Problems to be solved by the invention]
Even now, even if you are in a place where you must turn off the power due to the influence of radio waves in a hospital etc., for example, if you record the message when the power is off, etc., the message sent during that time Can be received later when the power is turned on. However, when the user of the mobile device is waiting for an urgent message, it is necessary to know the incoming call when receiving the incoming call. In addition, if the user forgets to turn off the power, the mobile device may transmit it without calling from the mobile device.
[0006]
An object of the present invention is to provide a reception-only mode in which transmission from the mobile device side such as a hospital can be used in a place where transmission from the mobile device side is not preferable, and reception is possible only from the mobile device side.
[0007]
It is another object of the present invention to automatically shift to the reception-only mode without requiring any operation by the user on the mobile device side when moving to an area where transmission of the mobile device is not preferable.
[0008]
[Means for Solving the Problems]
To achieve the above object, the present invention provides a mobile communication network system including a base station that transmits a notification signal including identification of a restricted area or a non-restricted area, a mobile device, and a control station that controls the mobile device. , the mobile station monitors the broadcast signal, when detecting a change from a non-limiting area to the restricted area, and sets itself to receive-only mode, to transmit a receive-only mode setting request to the base station When the base station receives the reception-only mode setting request from the mobile station, the base station transmits the reception-only mode setting request from the mobile station to the control station and receives the reception-only mode setting request. The control station stores in the database that stores the state of the mobile device that the mobile device that has transmitted the reception-only mode setting request is in the reception-only mode, and sets the reception-only mode. For transmission to the mobile station, using the paging channel, and performs transmission does not require a response.
[0009]
When a mobile device enters the restricted area, the mobile device is automatically set to the reception-only mode.
[0010]
As a result, in the present invention, by providing a reception-only mode, a message can be received even in a place where transmission is not desired.
[0011]
Transmission to the mobile device in the reception- only mode is character information, and this information can be information notifying that a voice message has been accumulated. These transmissions are performed a plurality of times.
[0012]
In this way, the message is surely received by the mobile device.
[0013]
In addition, the mobile device monitors the notification signal, and when detecting that the mobile device has changed from the restricted region to the non-restricted region, the mobile device releases itself from the reception-only mode.
[0014]
Accordingly, when the mobile device enters the non- restricted area, the mobile device can be automatically released from the reception-only mode.
[0015]
In addition, the mobile device stores the history of messages received during the receive-only mode, and when the receive-only mode is canceled, the mobile device transmits the received message history to confirm delivery based on the received message history sent. To be able to do.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described in detail with reference to the drawings.
[0017]
2 and 3 are diagrams for explaining an embodiment of the reception-only mode of the present invention. FIG. 2 illustrates the switching of the mobile device to the reception-only mode. FIG. 3 is a diagram for explaining an incoming call in the reception-only mode. 2 and 3, the same reference numerals are assigned to the same components as those in FIG.
[0018]
<Receive only mode setting>
2 and 3 can set the reception-only mode. In the mobile device 102 set in this mode, even when a signal that requires a response is transmitted from the base station 112 or the like, the mobile device 102 does not return a response but simply receives it. The setting to the reception-only mode is set by a specific operation of the mobile device 102 (for example, pressing a specific function key or transmitting to a specific number). This setting is preferably performed before entering an area where transmission is prohibited, such as a hospital.
[0019]
In FIG. 2, when a specific function key of the mobile device is pressed, a specific number (# 1234) is transmitted ((1) in FIG. 2), and the mobile device 102 enters the reception-only mode.
[0020]
The base station 112 that has received a specific number from the mobile device 102 identifies the home memory (HLR) 134 to be accessed from the mobile device number (telephone number) or the like given to the received signal (FIG. 2 ( 2)). Information indicating that the mobile device number and the reception-only mode are set is transferred to the identified home memory 134 ((3) in FIG. 2). The received home memory 134 indicates that the mobile device is in the reception-only mode in the field indicating the reception-only mode of the subscriber information of the mobile device 102 in the home memory 134 ((4) in FIG. 2). This is done, for example, by setting a flag in the field. Thus, the user has registered the mobile device 102 in the reception-only mode and the mobile communication network that the mobile device 102 is in the reception-only mode.
[0021]
The mobile device 102 in the reception-only mode does not perform any action of emitting all radio waves such as location registration and response to incoming calls as well as transmission.
[0022]
In order to cancel the reception-only mode, for example, the above-mentioned specific function key is pressed again. The mobile device 102 cancels its own reception-only mode, and transmits the same signal as in the above setting. As a result, the flag indicating the reception-only mode in the home memory 134 is canceled. Thus, the mobile device 102 side and the mobile communication network side cancel the reception-only mode.
[0023]
<Receive in receive-only mode>
Next, communication with the mobile device 102 set to the reception-only mode will be described with reference to FIG.
[0024]
In FIG. 3, for example, a case where a call is made from the telephone 144 of another network (public telephone network) to the mobile device 102 set in the above-described reception-only mode will be described. When the telephone number is transmitted from the telephone 144 ((1) in FIG. 3), it is notified to the gateway exchange node 124 which is a connection node with the public line of the mobile communication network. The gateway exchange node 124 specifies the home memory to be accessed based on this telephone number, and inquires of the home memory 134 about the subscriber's status and location registration area ((2) in FIG. 3). In the home memory 134, it is registered that the mobile device 102 is in the reception-only mode. Therefore, the home memory 134 notifies the gateway exchange mode 124 that it is registered in the reception-only mode. Upon receiving this notification, the gateway exchange mode 124 informs the user of the telephone 144 that the mobile device 102 is in the reception-only mode by voice. Then, the user is also notified that the notification by characters is possible ((3) in FIG. 3).
[0025]
The user inputs a message using characters in the same manner as the pager input from the button of the telephone 144 ((4) in FIG. 3). The message is stored in the exchange node 122 in the location registration area registered in the home memory 134 (FIG. 3 (5)). The accumulated message is transmitted together with the identification of the mobile device by using the paging channel from the base station 112 corresponding to the location registration area ((6) in FIG. 3). Usually, there are a plurality of base stations corresponding to the location registration area. A message is repeatedly transmitted from the base station 112 a predetermined number of times ((7) in FIG. 3). The base station 112 does not expect a response from the mobile device for this message transmission.
[0026]
The mobile station 102 constantly monitors the paging channel even in the reception-only mode, and receives and displays a message transmitted with its own identification added. Since it is transmitted a plurality of times, the probability that the mobile station 102 receives the message is high. At this time, no transmission is performed from the mobile device 102 such as a response to the transmission from the base station or a location registration when the area changes.
[0027]
In the above description, the mobile device 102 can receive a text message, but a voice message can be transmitted to the mobile device.
[0028]
In this case, when notifying that the mobile device 102 is in the reception-only mode, it is notified that a voice message is also possible, and the user is allowed to select what type of message to send. This selection is performed, for example, by pressing a number button. When the user selects a voice message, the voice is stored in the same manner as the voice mail message recording.
[0029]
In order to transmit this voice message, first, the user is notified by text that there is a message from the telephone 144 user. In this notification, the identification (telephone number) of the caller can also be informed and displayed. When the user of the mobile device 102 in the reception-only mode sees the character display of this notification, the user exits the area where transmission from the mobile device such as a hospital is restricted, then cancels the reception-only mode, Similarly, receive voice messages.
[0030]
<Auto receive only mode setting>
In the above description, it has been described that the user sets the reception-only mode manually. However, if the user does not notice that he / she has entered an area where transmission is restricted, or if he / she forgets to set the reception setting mode, the mobile device will respond with a response when a call is made to the mobile device. May be sent from. In order to prevent this, it is necessary to provide a transmission restricted area and automatically set the reception only mode when the mobile device moves to this area. The setting of the automatic reception only mode will be described with reference to FIG.
[0031]
In FIG. 4, a base station 212 and a base station 216 are in charge of non-restricted areas (normal cells) 202 and 206 that do not restrict transmission, respectively. The base station 214 is in charge of the restricted area 204 where transmission is restricted between the non-restricted areas 202 and 204.
[0032]
The broadcast information from the base station to the mobile station includes information on whether it is a non-restricted area or a restricted area. This notification information is constantly received by the mobile device and is used to monitor whether the area where the mobile device is located is a restricted area.
[0033]
When the mobile device 222 in the non-restricted area 202 enters the non-restricted area, the mobile device 222 enters the restricted area according to the information included in the broadcast information received from the base station 214. Is detected. When detecting that the mobile device 222 has entered an unrestricted area, the mobile device 222 sets itself to the reception-only mode and informs the base station 214 that the reception-only mode has been set. Since this procedure is the same as the manual setting of the reception-only mode, the details are omitted. Thus, the mobile device 222 that has entered the restricted area is automatically set to the reception-only mode.
[0034]
Further, when the mobile device 224 in the restricted area 204 leaves the adjacent non-restricted region 206, the mobile device 224 is identified from the restricted area by the information included in the broadcast information received from the base station 216. Detect that you have left. When detecting that the mobile device 224 has left the restricted area, the mobile device 224 releases itself from the reception-only mode and notifies the base station 214 of the release of the reception-only mode. Since this procedure is the same as the manual release of the reception-only mode, the details are omitted. Thus, the mobile device 224 that has left the restricted area is automatically released from the reception-only mode.
[0035]
In the above-described setting of the reception-only mode, transmission from the mobile device is accompanied. Therefore, when providing a limited area, it is necessary to set the boundary of the limited area where transmission is performed in accordance with the mode setting in consideration thereof.
[0036]
The procedure for setting the automatic reception mode described above is when the user is not making a call using the mobile device. A case where the user moves from the unrestricted area to the restricted area during a call will be described.
[0037]
When it is detected from the notification information that the mobile device 222 has moved from the non-restricted area to the restricted area during the call, the mobile device interrupts the call and informs the restricted area by voice, Forcibly terminate the call. Then, the self-reception-only mode is set and the above-described reception-only mode setting procedure is performed.
[0038]
Alternatively, although it is the same until the user is notified that the restricted area has been entered by voice, it is also possible to wait for the user to enter the reception-only mode until the user ends the call.
[0039]
<Confirmation of delivery>
In the receive-only mode of FIG. 3, there are times when the mobile device 102 wants to reliably receive a message sent from the telephone 144. At this time, transmission is performed by specifying delivery confirmation. If this is specified, since the reception confirmation is sent from the mobile device side when the mobile device leaves the restricted area, a message can be sent reliably. This delivery confirmation procedure will be described with reference to FIG.
[0040]
When delivery confirmation is required, the user sending the message registers in the mobile communication network that delivery confirmation is required when sending the message. This is registered in the home memory 134, for example. In FIG. 5, user A and user B who are outside the mobile communication network respectively send message #a and message #b that require delivery confirmation to subscriber α of the mobile communication network (in FIG. 5). (See (1) and (2)).
[0041]
The mobile communication network that has received the message gives a number to each subscriber for the message that needs delivery confirmation (see (3) in FIG. 5). The message assigned with this number is stored in the subscriber exchange node 122 together with the assigned number (see (4) in FIG. 5). The base station 112 transmits to the mobile device 102 a message, identification of the transmission source, and the fact that delivery confirmation is necessary, a plurality of times (see (5) in FIG. 5).
[0042]
When the mobile device 102 receives the message of the character from the user and the identification of the sender (telephone number) that the delivery confirmation is necessary, the mobile device 102 stores the received history (see (6) in FIG. 5). . This is done by storing the added number. In the example of FIG. 5, it is shown that the message with the added number (# 3) has not reached the mobile station 102 side.
[0043]
When the reception-only mode of the mobile device 102 is canceled (beside the restricted area), the received message history stored in the mobile device 102 is transmitted to the mobile communication network (see (7) in FIG. 5). ) To confirm delivery. That is, all the numbers assigned to the received messages stored in the mobile device 102 are sent to the base station. When receiving a delivery confirmation from the mobile device, the node that stored the message (subscriber switching node 122 in FIG. 5) checks the history and responds to the message that is clearly sent. Cancels the memory (see (8) in FIG. 5). A message that is found not to be received by the mobile device 102 based on the history sent when the reception-only mode is canceled is sent to the mobile device again (see (9) in FIG. 5). This is done in communications with normal responses.
[0044]
In the above example, the delivery confirmation is designated from the side sending the message to the mobile device, but the delivery confirmation may be always performed. In addition, it may be specified that delivery confirmation is performed from the mobile device side.
[0045]
In this way, by performing the delivery confirmation, the message is surely transmitted to the mobile device.
[0046]
【The invention's effect】
As described above, in the present invention, a message can be received even in a place where transmission is not desired by providing a reception-only mode.
[0047]
It is also possible to provide a base station corresponding to an area where transmission is not desired to be a restricted area, and when the mobile apparatus enters the restricted area, the mobile apparatus can be automatically set to the reception-only mode. By storing the history received in the reception-only mode in the mobile device, delivery confirmation can be performed when the mobile device is released from the reception-only mode.
