2. Description of the Related Art FIG. 6 is a block diagram of a mobile communication system for explaining a conventional technique. Subscriber 1 is mobile communication network A
And has a roaming contract with the mobile communication network B. The communication terminal, in this case, the mobile station 2 is accommodated in the exchange 31, and the communication line between the communication terminal 2 and the exchange 31 is connected by a wireless line via the wireless base station 51. The database 41 stores contract information on the subscriber 1 and the communication terminal 2 who have subscribed. That is, for each identifier (personal number) PID of each subscriber who has contracted with the communication network A, the type (class) of the contract and a roaming number (first logical number) given when moving to another communication network RON and the like are stored in the subscriber information area 61,
In addition, information indicating the type (class) for each identifier (mobile device number) SID of each mobile device, and location information ZN where the mobile device is located are stored in the mobile device information area 71,
Furthermore, when a subscriber who has contracted with another communication network receives a service on the own communication network, a temporarily provided roaming number R
Contract information (class) related to the subscriber is stored in the other communication network subscriber area 81 for each ON. The exchange 31 is connected to the database 41 via a control line, and can search for data stored in the database 41. The exchange 31 is connected to an exchange 32 of another communication network B by a communication line, and the database 41 is connected to a database 42 of another communication network B by a control line.

[0003] When a subscriber 1 owns his / her mobile unit 2 and performs communication by moving between mobile communication networks A and B, his / her contract information is transmitted to the mobile communication system to which the subscriber 1 subscribes. By transferring from the network A to the mobile communication network B in which the subscriber is located, the mobile communication network B in which the subscriber 1 is located treats the control for the moved subscriber 1 as a local network subscriber. A method has been conventionally considered, which is shown in FIG.

[0004] When a subscriber 1 communicates in a communication network B to which he or she has not subscribed, when the subscriber 1 moves to the communication network B, the identifier of the subscriber (hereinafter referred to as a subscriber number). Then, a "location registration request" including the identifier of the owning mobile unit 2 (hereinafter referred to as mobile unit number) is sent to the exchange 32 of the communication network B (S1). The exchange 32 sends a "location registration request" including the subscriber number and the mobile station number to the subscriber database 42 (S2). The database 42 translates the received subscriber number and translates the received subscriber number into a first logical number (hereinafter referred to as a roaming number) temporarily assigned to manage the subscriber when the subscriber is not the own network subscriber.
RON) and store it for that subscriber number. Further, the subscriber number and the roaming number are notified to the database 41 of the communication network A (hereinafter referred to as the home network) to which the subscriber has subscribed (S).
3). The database 41 of the home network A stores the roaming number for the subscriber number, and transfers the contract information of the subscriber to the database 42 of the visited network B (S
4). In the visited network database, the received contract information of the subscriber is stored.

[0005] According to the above-described method, the subscriber 1 can receive an incoming call at the owned mobile station 2 in the following procedure. That is, as shown in FIG. 8, when an incoming call is generated for a certain subscriber 1, the subscriber number is translated, and the exchange 3 of the communication network A to which the subscriber has subscribed.
1 (S1). The exchange 31 sends a "reception information read request" including the subscriber number to the database 41 (S2). The database 41 searches for an area indicated by the received subscriber number. If the subscriber is roaming to the other network B, the roaming number is stored, and a "reception information read response" including the roaming number is returned to the exchange 31 (S3). Upon receiving the roaming number, the exchange 31 translates the roaming number, finds out the communication network B in which the subscriber 1 is located, and connects to the exchange 32 of the communication network B (S4). . The exchange 32 in which the subscriber is located sends an "incoming information read request" including the received roaming number to the database 42 (S5). In the database 42,
The information stored in the area indicated by the roaming number is searched, and an "incoming information read response" including the contract information of the subscriber is returned to the exchange 32 (S6). The exchange 32 translates the obtained contract information of the subscriber and executes an incoming connection (S7).

In the above description, the identifier of the subscriber and the identifier of the mobile station have a one-to-one correspondence. However, the subscriber owns the personal number and contracts to receive the service with the communication network,
There is a personal communication system that designates (registers) an arbitrary mobile device in the communication network as a destination (hereinafter referred to as “incoming call registration”) so that an incoming call for the subscriber is received by the registered mobile device. In this personal communication, an incoming call can be received even if a subscriber moves between different networks by the method described below.

That is, as shown in FIG. 9, when a mobile station 2 registered (designated) as a called party by a subscriber moves to another communication network B, the mobile station 2 sends a "location registration request" to the communication network B.
(S1). The exchange 32 sends a "location registration request" including the mobile station number of the mobile station 2 to the database 42 (S2). The database 42 translates the mobile unit number to know the communication network A to which the mobile unit 2 has subscribed, and recognizes that the mobile unit 2 is a mobile unit accommodated in another network. A "mobile station location registration request" for requesting contract information on the mobile station number is sent to the database 41 of the mobile station (S).
3). The database 41 of the home network A includes the information on the mobile unit number in the "mobile unit location registration response" and returns it to the requesting database 42 (S4). At this time,
The returned information includes the subscriber number registered for the mobile station. Database 42 of mobile network
Then, the returned mobile device information is stored in the area pointed to by the mobile device number, and a "location registration response" including the subscriber number registered for the incoming call is returned to the exchange 32 (S5).

The exchange 32 sends a "user registration request" including the subscriber number and the mobile station number included in S1 to the database 42 in order to obtain contract information on the subscriber number registered for the incoming call. (S6). The database 42 translates the subscriber number to know the communication network A to which the subscriber has subscribed, and temporarily transmits to the subscribers other than the own network in order to manage the subscriber in the own network. A roaming number is assigned, and a "user location registration request" including the roaming number is sent to the database 41 of the communication network (home network) A to which the subscriber has subscribed (S7). In the database 41 of the home network A, the roaming number is stored for the subscriber number, and the contract information on the subscriber number is included in the “user location registration response” and transferred to the database 42 of the visited network B (S).
8). In the database 42 of the visited network B, the returned subscriber contract information is stored in an area that can be searched by the subscriber number or the roaming number assigned to the subscriber number, and the exchange 32 is referred to as “user registration”. Response "is returned (S9). Since the mobile station number is also included in S6, the subscriber information in the database also stores the number of the destination mobile station designated by the subscriber.

Next, FIG. 10 shows a method for terminating connection to a subscriber located in a communication network B other than the home network A. When an incoming call is made to a certain subscriber, the subscriber network is translated by translating the subscriber number to the communication network A to which the subscriber has subscribed.

[0010]

In personal communication, a subscriber can receive an incoming call by registering with an arbitrary communication terminal in a communication network to which the subscriber is subscribed. The disadvantage that the registration procedure must be performed every time the registration is changed, even for communication terminals that are frequently used, such as communication terminals at work, even if they do not own the terminal, and the procedure cannot be omitted. was there.

[0011] In addition, when registration is not performed, there is a disadvantage that incoming calls to the subscriber cannot be connected.

[0012]

According to the first aspect of the present invention, a destination communication terminal (an unregistered incoming communication terminal) in a state where the identifier of the destination communication terminal registered by the subscriber does not exist. Is stored in the database of the home network of the subscriber, and when an incoming call arrives at the subscriber, the exchange can refer to the database to know the identifier of the registered destination communication terminal for the subscriber. If you can't
The identifier of the destination communication terminal of the subscriber at the time of non-registration is known by referring to the database, and incoming connection is made to the communication terminal.

The invention of claim 1 may be applied to a fixed terminal or a mobile terminal as a communication terminal, that is, to both personal fixed communication and personal mobile communication. Each of the second and third aspects of the present invention solves a problem that occurs in the personal mobile communication storing the identifier of the destination communication terminal at the time of non-registration according to the first aspect of the present invention. According to the second aspect of the present invention, a subscriber enters into a subscription contract with one communication network (home network), enters into a roaming contract with another communication network, and receives a communication service by moving between the plurality of communication networks. When a destination mobile device is registered in the destination communication network, or when a mobile device that has already been registered moves to another communication network, a roaming contract with the communication network is made in the database of the destination communication network. Is assigned a first logical number (roaming number) for managing the subscriber in the communication network, stores an identifier of a mobile station registered as a destination of the subscriber, and The first logical number is transferred to the home network. In the home network database,
The first logical number of the transferred subscriber is stored for the subscriber. When an incoming call for a subscriber occurs, the exchange of the communication network in which the incoming call originated connects the incoming call to the exchange of the home network of the subscriber, and the home exchange is the subscriber to be terminated. , From the database, connects the incoming call to the exchange of the communication network in which the subscriber is located, and the connected exchange is stored in the database of the communication network. In the personal mobile communication method of knowing the identifier of the called mobile station corresponding to the first logical number and making a call connection to the subscriber to the mobile phone, the mobile phone receives the call without the registration of the called mobile station from the subscriber. The identifier of the destination mobile device (the destination mobile device at the time of non-registration) is stored in the database, and when the destination mobile device at the time of the non-registration moves between communication networks, the database of the communication network to which the mobile device has moved is stored in the database. ,That Subscribers motives are the unregistered when the incoming call destination mobile device, first managed by the communication network 2
A logical number (second roaming number) is given, an identifier of the destination mobile station at the time of non-registration is stored, and the second logical number is transferred to the home network of the subscriber. The home network database stores the transferred second logical number for the subscriber. When an incoming call for a subscriber occurs, the communication network in which the incoming call originated connects the incoming call to the home network of the subscriber to be terminated and, in the home network database, the subscriber to be terminated When the first logical number is stored, the first logical number is referred to, and when the first logical number is not stored, the second logical number is referred to, so that the subscriber can be referred to. The incoming call is connected to the exchange of the communication network in which the area is located.

According to the third aspect of the present invention, when a request for registration, change, or deletion of a destination mobile station identifier for a subscriber is received from the switching center, the identifier of the mobile station is stored in an area of the identifier of the subscriber in the memory. If the mobile station that is the destination of the subscriber is roaming, the first logical number that is the address at the time of the incoming call to the roaming destination network is stored in the memory. When a request for reading a mobile station identifier to be a destination of the subscriber is received from the exchange, the stored mobile station identifier is returned to the subscriber, and if the subscriber is roaming. For example, in the personal mobile communication database for returning the first logical number serving as the destination address to the visited network, the identifier of the destination mobile station is recorded in a state where the destination mobile station identifier is not registered by the subscriber. Means for storing a second logical number serving as an address at the time of an incoming call to a roaming destination network when the called mobile station at the time of unregistering is roaming; Upon receipt of the read request from the exchange, means for checking whether the destination mobile station for the subscriber is roaming, means for checking the presence or absence of the destination mobile station identifier registered by the subscriber, If there is a registered mobile station identifier, if there is no means for returning the mobile station identifier or the first logical number to the exchange, and if there is no destination mobile station identifier registered by the subscriber,
Means for returning the identifier or the second logical number of the destination mobile station at the time of non-registration to the exchange.

[0015]

An embodiment of the present invention will be described with reference to the drawings. In the present invention, the database 4 in each communication network is used.
i, as shown in FIG. 1A, when a subscriber information area 6i, a mobile device information area 7i, and another communication network subscriber area 8i are provided and a default receiving area 9i is provided, and the subscriber does not register the incoming call. The subscriber number and the destination mobile station number SID-d are registered as a set in the default reception area in advance as the destination of the
When the incoming call registration is released, when there is an incoming call to the subscriber, the incoming call can be received at the mobile station designated by the default incoming call registering means.

That is, processing for an incoming call is performed as shown in FIG. However, it is assumed that the subscriber is located in the communication network A to which the subscriber has subscribed. When an incoming call is generated for a certain subscriber, the subscriber number is translated, and thereby the exchange 3 of the communication network A to which the subscriber has subscribed.
1 (S1). The exchange 31 sends a "reception information read request" including the subscriber number to the database 41 (S2). The database 41 searches for an area indicated by the received subscriber number. If there is a mobile station number registered for incoming call in the search, the mobile station number is returned to the exchange 31 as a mobile station to be connected to the incoming call in the "call information read response". If the mobile phone number does not exist, the mobile phone number SID-d designated as the default incoming call registration destination is searched and returned to the exchange 31 in the "call incoming information read response" (S3). The exchange 31 sends a "reception information read request" including the received mobile station number to the database 41 (S4). In the database 41, the mobile unit number SI
The information stored in the area pointed to by Dd is searched, and an "incoming information read response" including the contract information and the location information on the mobile station is returned to the exchange 31 (S
5). The exchange 31 translates the information on the called subscriber and the information on the mobile station calling the called call to execute a call connection (S6).

In such personal communication, even if the registration of the destination mobile station is canceled for some reason, an incoming call is made to the destination mobile station at the time of non-registration. The invention of claim 1 is applicable to personal communication of a fixed terminal. But the mobile station 2 ₁ subscriber, as shown in FIG. 1B for example, in personal mobile communication arrives registered exists in different network B than the home network A, the mobile station 2 ₂ which was further default call registered, Home both network a, the mobile station 2 ₁ is to be located in different communication networks C also a communication network B to serving the incoming register. In this way, when the mobile device that has registered the incoming call and the mobile device that has registered the default incoming call move between communication networks independently, when the incoming call for the subscription is registered, the incoming call is connected to the incoming call registration destination. When there is no incoming call registration, there is a problem that there is no means for connecting to the default incoming call registration destination.

This problem is solved by the invention of claim 2, wherein a roaming number is captured in a home network database when a mobile station of a default destination registration destination of a subscriber performs location registration between networks, The roaming number stored by the call registration across the subscriber's network is stored independently from the roaming number stored by the call registration across the subscriber's network. The associated roaming number is made valid as the destination of the incoming call.

FIG. 3 shows a part of a system configuration to which the present invention is applied.

This is the same as before.

According to the present invention, when a mobile station designated by a subscriber as a default destination roams, a roaming number (second logical number) assigned to a subscriber registered as a default destination for the mobile station. Is stored in the database 4i. When a mobile station designated as a destination by a subscriber moves to another communication network C, the mobile station sends a "location registration request" to the exchange 33 of the communication network C as shown in FIG. (S1). Exchange 33
Then, a "location registration request" including the mobile unit number of the mobile unit is sent to the database 43 (S2). The database 43 translates the mobile unit number to find the communication network A to which the subscriber is subscribed, and recognizes that the mobile unit is accommodated in another communication network. A "mobile station location registration request" for requesting contract information relating to the mobile station number is sent to 41 (S3).
The database 41 of the home network A includes the information on the mobile unit number in the "mobile unit location registration response" and returns it to the requesting database 43 (S4). At this time, the returned information includes the subscriber number registered as the default incoming call for the mobile device. In the database 43 of the visited network C, the returned mobile unit information is stored in the area indicated by the mobile unit number, and the subscriber number registered as the default incoming call to the exchange 33 is referred to as a “location registration response”. And returned (S5).

The exchange 33 sends a "user registration request" including the subscriber number to the database 4 in order to obtain contract information on the subscriber number registered in the default incoming call.
3 (S6). In the database 43,
By translating the subscriber number to know the communication network A to which the subscriber subscribes, a roaming number is temporarily given to subscribers other than the own network in order to manage the subscriber in the own network. (Hereinafter referred to as RON-d), and sends a “user location registration request” including the roaming number RON-d to the database 41 of the communication network (home network) A to which the subscriber has subscribed. (S7). In the database 41 of the home network A, the roaming number RON-d is stored for the subscriber number, and the contract information on the subscriber number is included in the “user location registration response” and transferred to the database 43 of the visited network C. (S8). The database 43 of the visited network C stores the returned subscriber contract information in an area that can be searched by the subscriber number, and returns a "user registration response" to the exchange 33 (S9).

FIG. 5 shows an example in which, when the subscriber cancels the incoming call registration, an incoming call is received at the mobile station designated by the default incoming call registration. The subscriber registers the incoming call with a mobile station located in a communication network B other than the communication network A to which the subscriber is subscribed. The registered mobile station is located in a communication network C different from the communication network B in which the mobile station is located, and the registration of the incoming call to the mobile station is released, and the subscriber is located in the communication network C. Shall be

When an incoming call is made to a certain subscriber,
By translating the subscriber number, the subscriber is connected to the exchange 31 of the communication network A to which the subscriber has subscribed (S
1). The exchange 31 sends a "reception information read request" including the subscriber number to the database 41 (S2).
The database 41 searches for an area indicated by the received subscriber number. If the subscriber is roaming, the roaming number RON is stored,
"Incoming information read response" including the roaming number RON
Is returned to the exchange 31, but if the subscriber has not registered the incoming call in any communication network and the mobile station specified in the default incoming call registration is roaming, the roaming number RON- is used as the roaming number. Only d is stored, and an "incoming information read response" including the roaming number RON-d is returned to the exchange 31 (S3).

In the exchange 31, the roaming number RON-
When d is received, translate the received roaming number,
It knows the communication network C in which the subscriber is located, and connects to the exchange 33 of the communication network C (S4). The exchange 33 in which the subscriber is located sends an "incoming information read request" including the received roaming number to the database 43 (S5). The database 43 returns an “incoming information read response” including information stored on the received roaming number to the exchange 33. At this time, since there is no mobile station number registered for incoming call, the mobile station number of the mobile station designated as the default incoming call destination is searched and returned to the exchange 33 in the "call information read response". (S6). The exchange 33 sends a "reception information read request" including the received mobile station number to the database 43 (S7). The database 43 searches for information stored in the area pointed to by the mobile station number, and returns an "incoming information read response" including contract information and location information on the mobile station to the exchange 33 (S8). The exchange 33 translates the information on the called subscriber and the information on the mobile station calling the incoming call to execute the incoming connection (S).
