Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a mobility management method, and particularly to a mobility management method that can continuously provide services as personal communication users and terminals move in a personal communication system. .

[Conventional technology]

FIG. 2 shows an example of a conventional mobility management method for a personal communication system. In the figure, 11 is a personal communication user on the calling side; 1. is the called personal communication user; 2. is the originating terminal, 2. is the called terminal, 3 is the network, 4 is the database, PTN8 is the personal communication number of the personal communication user 12 on the called side, RA2 is the routing address, and rMsI* is the terminal identifier. In the figure, the originating personal communication user 1. An example of an incoming call connection to the -sonal communication user 12 is shown.

In FIG. 2, the personal communication user 11 on the originating side sends the personal communication number PTNs of the personal communication user 12 on the receiving side to the network 3. In order to make a call connection to the personal communication number PTN, the network 3 makes an inquiry to the database 4 to obtain the routing address RA 2 to the access point of the called terminal 22 where P T N * is registered.

An access point, for example, indicates the location of a subscriber line accommodated by an exchange.

The database 4 collectively manages the personal communication number PTN, the routing address RA2, and a terminal identifier IMS If that identifies the receiving terminal 2□ that provides personal communication services to the personal communication user 12 on the receiving side. Routing address RA 2 is terminal 22
The access point 52 has the function of making a call connection.

After obtaining the routing address RA 2 and terminal identifier IMS 1 necessary for the call connection from the database 4 to the network 3, the access point 52 and the terminal 2 A call connection is made to the personal communication user 12 of .

FIG. 3 shows location registration of a personal communication user from another terminal, and FIG. 4 shows access point movement while the personal communication user communicates with a wireless terminal. In both figures, the same components as in FIG. 2 are denoted by the same reference numerals, and their explanations will be omitted. FIG. 3 illustrates movement of a personal communication user at a wireless terminal to an access point without communicating with the terminal.

From the situation shown in FIG. 2, there are two possible location registration patterns regarding the movement of the personal communication user 12. One is the called personal communication user 1 as shown in FIG.
2 Initially, the receiving terminal 22 was used, but another terminal 2
．． This is a pattern in which the user moves to and registers the location from there.

In this case, the location registration method is to store the personal communication number PTN in the database 4 and the called personal communication user 12.
The destination terminal 2. This is to register the routing address RA up to.

Further, as shown in FIG. 4, the personal communication user 12 on the receiving side at the receiving terminal 2□ or the wireless terminal is the receiving terminal 2! Do not continue communication using other access points 5.
．． This is the case when moving to .

In this case, the location registration method is personal communication number PT N
m and database routing address RA! needs to be updated.

As mentioned above, there are two types of location registration patterns associated with the movement of personal communication users. Zuni,
It performs location registration control between wireless terminals and network functions.

Furthermore, the location registration frequency, registration procedure, failure recovery procedure, and timer value regarding relocation registration control between the personal communication user's wireless terminal and the network function generally differ.

[Problem to be solved by the invention]

However, in the conventional method, location registration control having different attributes is processed all at once, which makes it impossible to achieve functional modularization and also leads to software complexity.

When realizing personal communication services in a system such as a car phone that provides services by moving the terminal, installing a new pig base as in the conventional method will reduce the mobility of the wireless terminal in the car phone system. The disadvantage is that the supporting functions overlap, leading to complicated information management and control procedures.

[Means to solve the problem]

The present invention provides a terminal identifier for identifying a terminal, a personal communication number for identifying a personal communication user, and an access point indicating a location from which the terminal accesses a network.
It consists of a routing address that enables call connection to the access point, the terminal identifier, the personal communication number, and a database that manages the routing address information, and the information in the database is changed as the personal communication user or terminal moves. In a mobility management method capable of guaranteeing continuity of service by updating a personal communication number, the personal mobility management means supports a relationship between a terminal telephone number and the personal communication number, and the terminal telephone number and the routing address in the database are updated. and a terminal movement management means that supports the relationship between the personal communication user and the terminal identifier, the personal management means updates a change in the relationship between the personal communication user and the terminal, and the relationship between the terminal and the access point is updated. The terminal movement management means updates the changes.

[Effect]

The present invention integrates the mobility management function into a single component in order to separate and define functions that support the mobility of personal communication users and the mobility of terminals having different attributes, and also integrates both functions singly or in combination. use.

〔Example〕

FIG. 1 shows an embodiment of the invention. In the figure, the same components as those in FIG. 2 are denoted by the same reference numerals, and the explanation thereof will be omitted.

In FIG. 1, 6 indicates a personal movement management means, and 7 indicates a terminal movement management means.

First, an example will be described in which an incoming call is connected to the personal communication user 12 on the receiving side via the personal communication user 11 or the calling side terminal 21. The network 3 receives the personal communication number PTN sent by the originating personal communication user 1 or the originating terminal 2, and stores the PTN in the database 4.
Inquire about the routing address to N. The personal movement management means 6 of the database 4 manages the relationship between the personal communication number PTN and the terminal telephone number DN2 of the receiving terminal 22. Here, the terminal telephone number DN2 may be a number that is disclosed to the user and dialed, or it may be a number that is privately defined by the network, such as a layer number that is attached to the published number. Or both are allowed.

The terminal telephone number DN2 has a one-to-one correspondence with the terminal identifier IMSI2, and the network manages the relationship such that DN and 1MSI2 always correspond as a pair. The personal movement management means 6 of the database 4 uses P obtained from the network 3.
The called terminal telephone number DN is obtained by TNa.

Next, the terminal movement management means 7 of the database 4 obtains the called terminal telephone number DN from the personal movement management means 6,
Based on this, the routing address RA to the called terminal 22 is determined.
, and obtains the terminal identifier IMSI2.

The network 3 connects to the personal communication user 12 on the called side via the access point 52 and the called side terminal 2□ based on the routing address RA t and terminal identifier IMSI2 to the called side terminal 2□.

In addition, in FIG. 1, the effects of the present invention do not change even if the personal movement management means 6 and the terminal movement management means 7 are provided in the database 4, or the databases are physically separated. However, in this case, information that can be directly transferred between the database having the personal movement management means 6 and the database having the terminal movement management means 7 is required. Therefore, for example, when a common signal network is used for signal transfer between both databases, the point code (PC') indicating the physical location of both databases is sent to both databases, or
It can be managed on the network 3 side.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to quickly realize personal communication services for services provided by terminal mobility such as car telephones, and to separate mobility with different attributes.
By defining it, it is possible to modularize the functions, and by supporting mobility by using each function singly or in combination, it is useful for flexibly responding to the sophistication of network functions and service expansion.
