Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a position information management system in a mobile communication system including a base station connected to an exchange, a mobile terminal, and a control station.

[0002]

2. Description of the Related Art In a mobile communication system, when a control station that manages location information and controls a connection destination of a mobile terminal based on the location information receives an incoming call request to the mobile terminal, it determines the connection destination of the call. To identify, the mobile terminal registers its location with the control station. The location registration area consists of one or more wireless zones. The wireless zone is an area in which the base station can communicate. The location registration area changes as the location of the user of the mobile terminal changes. When the caller dials the mobile terminal number, the exchange detects the mobile communication service identification number from the dialed number. When the exchange detects the mobile communication service identification number, the exchange sends a signal indicating an incoming call request to the mobile terminal to specify the connection destination of the mobile terminal.

The base station uses the control channel to notify the position information notification signal to the mobile terminals under its control at regular time intervals. The mobile terminal receiving this position information notification signal compares the position registration area information stored in the memory of the mobile terminal at the time of the previous position registration with the position information included in the received signal, and if different, the area is changed. It is determined that the terminal has moved, and a location registration request signal is transmitted to the control station via the base station. Based on the received position registration request signal, the control station executes an authentication process in order to check that the corresponding mobile terminal is an authorized subscriber terminal before updating the position information. First, an authentication request signal is transmitted to the mobile terminal. When the control station receives the authentication response signal from the mobile terminal and the authentication result is correct,
Rewrite the location information of the mobile terminal.

Next, the operation when the mobile terminal receives a call will be described. When the control station receives the incoming call request to the mobile terminal, the control station searches the location registration area information registered by the mobile terminal, and sends a paging signal to all the base stations in the location registration area. The base station transmits an incoming call signal to the subordinate mobile terminals using the control channel. When the mobile terminal receives the incoming call signal, the mobile terminal sends a response signal to the control station. Next, the control station sends an authentication request signal to the mobile terminal, receives an authentication response signal from the mobile terminal, and if the authentication result is correct, sets up the communication path between the calling terminal and the mobile terminal. , You can talk.

[0005]

In order to realize a mobile communication service, it is essential to carry out location registration every time the location registration area changes. However, since the number of mobile terminals increases when the mobile communication service spreads in full scale, the number of location registrations increases. Authentication processing is also required when performing location registration. The control channel between the base station and the mobile terminal is used not only for position registration but also for transmitting control signals for making and receiving calls. If the number of location registrations increases, the proportion of location registrations in the traffic of the control channel increases, which makes it difficult to make and receive calls. Furthermore, since location registration is performed each time the location registration area moves, if multiple mobile terminals enter the new location registration area at the same time by means of mass transportation such as buses or bullet trains, each terminal will register the location in the new location registration area. Therefore, there is a problem that the location registration process occurs in a burst.

An object of the present invention is to reduce the frequency of location registration in mobile communication, to prevent burst occurrence of location registration request signals, and to prevent a decline in incoming call success rate due to a decrease in location registration frequency. Especially.

[0007]

In order to achieve the above object, in the mobile communication system of the present invention, in a mobile communication system including a control station, an exchange, a base station, and a mobile terminal, a database used by the control station is stored. , A location schedule corresponding to the mobile terminal number is stored. The position schedule indicates a relationship between a time corresponding to a mobile terminal number and a planned position existing at that time. Further, the mobile terminal is provided with means for storing the location schedule of the terminal itself and analyzing the location schedule. The position schedule data of the mobile terminal and the position schedule data of the mobile terminal in the database used by the control station are the same. The network internal routing address is registered as the position information of the position schedule data. The correspondence between the location and the network internal routing address is managed by the network maintainer. Therefore, the data is input through the maintenance person of the maintenance center based on the address specified by the subscriber, and the same data is held in the mobile terminal. Therefore, the control station downloads the input data to the mobile terminal. Have.

The mobile terminal has a clock circuit, and when the mobile terminal changes the location registration area, it compares the location schedule registration time with the current date and time. If it is within the schedule registration time, the connection destination of the position schedule data and the position information received from the base station are compared, and if they match, the position registration request signal is not transmitted to the control station.

Further, the mobile terminal has a function of selecting location registration stop.

Further, when the control station receives the incoming call request to the mobile terminal, it has means for determining the connection destination of the call according to the location schedule information. Further, it has means for enabling registration of a plurality of location registration areas as connection destinations and sequential search when receiving an incoming call to a mobile terminal.

[0011]

In the present invention, the same location schedule is stored in the database used by the control station and the mobile terminal. The mobile terminal analyzes the location schedule data, determines the location registration area corresponding to the time, and if the location registration area where the mobile terminal currently exists and the location registration area described in the location schedule are equal, the location registration is performed. Have a means not to do. When the control station receives the incoming call request to the mobile terminal, it has means for analyzing the location schedule data and determining the connection destination of the call. Therefore, it is possible to suppress the location registration request signal from being transmitted to the control station every time the location registration area in which the mobile terminal is located changes, and to reduce the location registration request signal. In addition, since the connection destination of the incoming call to the mobile terminal is determined based on the location schedule data owned by the database used by the control station, it is possible to prevent the success rate of incoming calls from decreasing due to the reduction in location registration. it can. In addition, by reducing the location registration process that uses the control channel between the base station and the mobile terminal, the control channel can be used for outgoing and incoming calls. Is easier to do.

The location schedule data connection destination is input from the maintenance center via the maintenance person, and means for downloading the input data to the corresponding mobile terminal is provided so that the maintenance person manages the location schedule connection destination. It is possible to register a network internal routing address to be used.

In addition, when the mobile terminal has the position registration stopping function, when the position registration stopping function is selected,
It is possible to further reduce the transmission of the location registration request signal.

Further, when a plurality of location registration areas are registered as connection destinations of the location schedule at the same time and an incoming call is received,
Since the control station has means for performing sequential search, it is possible to prevent the success rate of incoming calls to the mobile terminal from decreasing.

The mobile communication system comprises a maintenance center 9, a control station 2, a database 3, a plurality of trunk line exchanges 5 (5a ...
5b), the subscriber line exchange 6 (6a to 6b), the base station 7 (7a to 7d) having the wireless zone 8 (8a to 8d) which is a communicable area, and the mobile terminal 1 (1a to 1b).
Is configured as a basic system.

The control station 2 has a function of utilizing the information stored in the database 3 to perform a process of identifying the connection destination of the mobile terminal 1 and an authentication process. The control station 2, the trunk line exchange 5, and the subscriber line exchange 6 are connected by a signal transfer network 4.

The maintenance center 9 performs information registration processing by a maintenance person. The maintenance center 9 and the control station 2 are, for example,
It is connected by an information transfer network 20 such as X.25.

The subscriber line exchange 6 has a function of detecting a mobile communication call that requires access to the control station 2. For example, when the caller dials a number including a mobile communication service identification number and a mobile terminal number, the subscriber line exchange 6 detects the mobile communication service identification number in the dial number and determines that the call is a mobile communication call. Since the subscriber line exchange 6 cannot specify the position of the mobile terminal from the dial number, a signal including the dial number is transmitted to the control station 2. The control station 2 converts the dial number into a connection destination registered by the mobile terminal, and returns a signal including the connection destination number to the subscriber line exchange 6. The subscriber line exchange 6 performs connection processing based on the connection destination number. The general basic connection call is closed by the subscriber line exchange 6 and the trunk line exchange 5 for processing.

The trunk line exchange 5 is an accommodation subscriber line exchange 6
Has a connection processing function between different terminals.

The base station 7 is housed in the subscriber line exchange 6 and performs wireless communication with the mobile terminal 1. For example, when an incoming call to the mobile terminal 1 is received, a signal for notifying the incoming call to the subordinate mobile terminal 1 is transmitted, and if there is a response from the mobile terminal 1,
A call path is set up with the calling terminal 1.

FIG. 2 shows the configuration of the control station.

FIG. 4 shows an example of the data structure of the position schedule data for the mobile terminal, which is included in the database. That is, the mobile terminal number, the schedule subscriber identification section that indicates the subscription status of the location schedule, the registration identification section that indicates the registration status of the location schedule, the location schedule table number, the location registration area information that indicates the connection destination when the location schedule is not registered, It has a data table composed of the position registration area information update time indicating the update time of the position registration area information. Further, it has a location schedule table composed of connection destinations such as registration date, registration time, location registration area, etc. corresponding to mobile terminal numbers. As shown in FIG. 6, it is possible to register a plurality of connection destinations.

By registering the location schedule data, the location registration destination of the mobile terminal can be specified without transmitting a location registration request from the mobile terminal to the control station.

FIG. 5 shows the processing flow executed by the control processor of the control station to connect the call to the mobile terminal when the call to the location schedule subscriber is detected.

When the control station receives the incoming call request including the mobile terminal number from the subscriber line exchange containing the caller (4
1) With reference to, for example, the data shown in FIG. 4 contained in the database, it is determined whether the user is a schedule subscriber (42). If it is a schedule subscriber, it is determined whether the schedule is being registered (43). If the schedule is being registered, the position schedule table number is acquired (44), and the current date and time is acquired using the clock circuit of the control station (45). Then, it is determined whether the mobile terminal is in the time zone in which the schedule is registered by comparing with the current date and time (46). If it is in the registration time zone, obtain the location registration area information update time (4
7) It is determined whether or not the position registration area information is updated within the position schedule registration time (48). If the location registration area information is not updated within the location schedule registration time, the connection destination registered in the location schedule is acquired (49).

If the user is not a schedule subscriber, is not in the process of registering the schedule, is not in the registration time zone of the position schedule, or if the position registration area information is updated within the registration time of the position schedule, the position registration area corresponding to the mobile terminal number is displayed. Information is acquired (54).

After obtaining the connection destination, a call signal including the connection destination information is transmitted to the subscriber line exchange that accommodates the caller, and is transmitted to all the base stations included in the location registration area via the trunk line exchange (50). In the base station, the paging signal including the mobile terminal number is reported to the mobile terminals under its control. If there is a response from the corresponding mobile terminal, authentication processing is performed (52), then connection processing is performed (53), and if there is no response from the mobile terminal within a fixed time, the processing ends (55).

Since the control station has the position schedule data analysis means, when an incoming call is made to a mobile terminal which is registering the position schedule, it becomes possible to perform connection processing according to the position schedule.

FIG. 6 shows an example of a data structure which is used when sequentially searching for connection destinations and is included in the database.

For example, it is a data table for registering the registration identification section, the first connection destination, the second connection destination, and the third connection destination indicating the registration status of the sequential search corresponding to the mobile terminal number. It is also possible to specify a fixed terminal, a mailbox, an announcement machine, or the like as the connection destination.

FIG. 7 shows a processing flow of sequential search executed by the control processor of the control station when, for example, three connection destinations are registered.

When the control station receives the incoming call request including the mobile terminal number from the subscriber line exchange containing the caller (6
1), for example, referring to the data of FIG. 6 included in the database, it is sequentially determined whether or not the user is a search registrant (6
2). If it is a registrant, it acquires the first connection destination (63), sends a call signal including the connection destination information to the subscriber line exchange that accommodates the caller, and the location registration area via the trunk line exchange. Is transmitted to all base stations included in (64), and the base station notifies the subordinate mobile terminal of a calling signal including the mobile terminal number.

If the person is not a sequential search registrant, the location registration area information corresponding to the mobile terminal number is acquired (75).

If the mobile terminal does not respond within a fixed time, it is judged whether the second connection destination is registered (6
6) If the registration is in progress, the second connection destination is acquired (6
7), a call signal including connection destination information is transmitted to a subscriber line exchange that accommodates the caller, and is transmitted to all base stations included in the location registration area via the trunk line exchange (68). A calling signal including the mobile terminal number is notified to the mobile terminals under its control. If the second connection destination has not been registered, the process ends (76).

When the mobile terminal does not respond within a fixed time, it is judged whether the third connection destination is registered (7
0), if it is registered, the third connection destination is acquired (7
1), a call signal including connection destination information is transmitted to a subscriber line exchange that accommodates a caller, and is transmitted to all base stations included in the location registration area via the trunk line exchange (72). A calling signal including the mobile terminal number is notified to the mobile terminals under its control.

If the mobile terminal does not respond within a fixed time, the process is terminated (76).

When the mobile terminal responds, authentication processing is performed (74), and then connection processing is performed (77).

With this, it becomes possible to register a plurality of connection destinations of the mobile terminal and sequentially search for the mobile terminal when an incoming call to the mobile terminal occurs. Therefore, the success rate of incoming calls to the mobile terminal is lowered. It can be prevented.

When a fixed terminal, a mailbox, an announcement machine, or the like is designated as the connection destination, if there is a response, the connection process is performed (77), and if there is no response, the process ends (76).

FIG. 8 shows an example of the data structure of the position schedule data contained in the memory of the mobile terminal. That is, a mobile terminal number, a schedule subscriber identification unit that indicates the subscription status of the location schedule, a registration identification unit that indicates the registration status of the location schedule, a location schedule table number, and location registration area information that indicates the location registration location when not registered in the location schedule. , A data table of location registration area information update times indicating location registration area information update times. Furthermore, it has a location schedule table consisting of registration date, registration time, and connection destination.

The conventional location registration mechanism is shown below.
The base station uses the control channel to notify the subordinate mobile terminals of the position information notification signal at regular time intervals. In the mobile terminal receiving this position information notification signal, the position registration area information stored in the memory of the mobile terminal and the position information included in the received signal are compared, and if different, it is determined that the area has been moved, A location registration request signal is transmitted to the control station via the base station.

FIG. 9 shows a processing flow for reducing this position registration request signal. This processing is executed by the control processor of the mobile terminal having the location schedule data. This is executed to determine whether or not the mobile terminal transmits the location registration request signal when the location information notification signal is received.

When the mobile terminal receives the position information notification signal including the position information from the base station (81), the mobile terminal determines whether it is a schedule subscriber or not while referring to the data shown in FIG. Perform (82).

If the user is a schedule subscriber, it is determined whether the schedule is being registered (83).

If the schedule is being registered, the position schedule table number is acquired (84) and the current date and time is acquired using the clock circuit (85). Then, it is determined whether the mobile terminal is in the time zone in which the schedule is registered by comparing with the current date and time (86). If it is in the registration time zone, the location registration area information update time is acquired (8
7) It is determined whether or not the position registration area information is updated within the position schedule registration time (88). If there is no update within the location schedule registration time, the location registration area information registered as the connection destination in the location schedule is acquired (89).

The location registration area information from the location schedule is compared with the location information in the location information notification signal received from the base station by the mobile terminal (90).
The mobile terminal does not transmit the location registration request signal (9
1). Only when they do not match, the mobile terminal transmits a location registration request signal to the control station via the base station (94).
The control station that receives the location registration request signal from the mobile terminal
Authentication processing is performed with the mobile terminal. If the authentication process is successful, the contents of the location registration area information corresponding to the mobile terminal number in the data table shown in FIG. 4 are rewritten to the location information included in the location registration request signal, and at the same time the location registration area information update time is updated. Rewrite.

If the user is a non-subscriber to the schedule, is not in the schedule registration, is not in the movement schedule registration time zone, or the location registration area information is updated within the location schedule registration time, the location registration area corresponding to the mobile terminal number is registered. Information is acquired (92).

The location registration area information corresponding to the mobile terminal number is compared with the location information in the location information notification signal received from the base station by the mobile terminal (93), and if they match, the mobile terminal sends a location registration request. No signal is transmitted (91).
If they do not match, the mobile terminal transmits a position registration request signal to the control station via the base station (94).

From the above, when the mobile terminal is present at the registration place during the location schedule registration time, it becomes possible to reduce the location registration request signal from the mobile terminal to the control station. For example, it is possible to reduce bursty position registration requests at places (stations, stops, concert halls, etc.) where many people arrive at the same time. Further, by reducing the number of location registration requests using the control channel between the base station and the mobile terminal, it becomes easier to make and receive calls using the control channel.

FIG. 10 shows an example of the data structure of the location registration stop information contained in the memory of the mobile terminal. That is,
It is a data table which consists of a mobile terminal number and a registration stop identification section that indicates whether or not a position registration stop is registered.

FIG. 11 shows a processing flow executed by the control processor of the mobile terminal to determine whether or not the location registration stopping means is used when the mobile terminal has the location registration stopping means. The position registration stop means that the mobile terminal does not transmit the position registration request signal.

When the mobile terminal receives the position information notification signal from the base station (101), for example, referring to the data shown in FIG. 10, it is judged whether or not the position registration stop is being registered (102). .

If registration is in progress, the position registration request signal is not transmitted (106).

If the registration is not in progress, the location registration area information corresponding to the mobile terminal number is acquired (103). The location registration area information corresponding to the mobile terminal number is compared with the location information in the location information notification signal received by the mobile terminal from the base station.
(104) If they match, the mobile terminal does not transmit the location registration request signal (106). Only when they do not match, the mobile terminal transmits a location registration request signal to the control station via the base station (105). Registration of location registration stop is performed by the mobile terminal user, for example, by selecting a specific button,
It is performed by a specific operation on the mobile terminal.

By the above means, when the position registration stop function of the mobile terminal is selected, the position registration request signal from the mobile terminal to the control station can be set to zero. Even when the location registration stop function is selected, the control station uses the location schedule to combine the connection destination determination methods described in FIGS. If it is in the street position, the incoming call to the corresponding mobile terminal becomes possible.

FIG. 12 shows a signal sequence when the maintenance person inputs information to the maintenance center and downloads the information to the mobile terminal via the control station, subscriber exchange and base station.

When the subscriber registers the location schedule and a plurality of connection destinations, the subscriber informs the maintenance person of the maintenance center of the registered contents. When the maintenance person who receives the notification inputs a command from the maintenance center 9 (111), a registration request signal is transferred from the maintenance center to the control station 2 (112). The control station performs information registration processing (113). When the position schedule information corresponding to the mobile terminal number is updated, the schedule registration request signal is sent via the subscriber exchange 6 and the base station 7 in order to load the position schedule information into the mobile terminal.
It transmits to the mobile terminal 1 (114-116). When the control station receives a response signal to this signal from the mobile terminal (1
17-119), the control station transmits a signal including the location schedule information to the mobile terminal (120-122). A signal transmitted from the base station to the mobile terminal at the time of registering the location schedule information has a signal format as shown in FIG. 13, for example. When the mobile terminal receives the location schedule information, the location schedule is registered (123),
After processing is completed, an end signal is returned to the control station (124-1).
26). Upon receiving the schedule registration completion signal, the control station transmits an end signal to the maintenance center (127).

By the above means, the network internal routing address managed by the maintenance person can be designated as the connection destination of the database used by the control station and the position schedule data owned by the mobile terminal.

[0066]

According to the present invention, even if the mobile terminal enters a new location registration area, the location registration request signal is not always sent,
There is no need to transmit to the control station via the base station, which has the effect of reducing the transmission of location registration request signals. Furthermore, it is possible to prevent the location registration processing from occurring in bursts. In addition, by reducing the location registration process that uses the control channel between the base station and the mobile terminal, the proportion of the control channel that can be used for outgoing and incoming calls increases, and the outgoing call from the mobile terminal and the incoming call to the mobile terminal are performed. It will be easier.

Further, a plurality of connection destinations of mobile terminals are registered,
By performing the sequential search, it is possible to prevent the success rate of incoming calls to the mobile terminal from decreasing.
