Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication terminal having a device which operates in a mobile radio communication system and can recognize a plurality of control information including area information and the like.

[0002]

2. Description of the Related Art In a mobile radio communication system in which a mobile communication terminal operates, a service area may be divided into a number of small zones to provide services. When providing services in this small zone system, there are many advantages such as effective use of frequencies, but some zones overlap.
That is, there may be an area where a plurality of pieces of control information including area information exist. The plurality of pieces of control information are not limited to a single company, and information of a plurality of companies may be mixed. However, a user who is in the situation of receiving services from a plurality of businesses cannot arbitrarily select a service (business) to be used conventionally.

As a specific example, TAC in Japan
S (Total Access Communicatons System For Japan)
There is a standard cellular telephone system. In Japan, the TACS standard cellular radiotelephone system is operated, but the service provider differs depending on the region. In addition, service areas of different businesses are close to each other, and in fact, there are areas where services of a plurality of businesses can be received. In the cellular radiotelephone service, when a line contract is established with a certain operator and the station is opened, basically, it can be used only in the service area of the operator who has made the contract, and cannot be used in the service areas of other operators. However, with an optional contract, it can be used in the service areas of other companies with which it is affiliated (roaming contract). In this case, it is possible to receive services from a plurality of different businesses.

An actual example is 199 by Nihon Keizai Shimbun.
On the map of “IDO / Cellular companies TACS service area” in 73 of the April 1994 issue of “Nikkei Trendy” released on April 1, 2004, the service areas of the Chubu region and the Kansai region are close to each other. You can see that Also, 16
On page 3, "" TACS Minimo "can be called in the metropolitan area plus the central area (the Tomei area is also completed from April), and can be called all over Japan in combination with cellular TACS roaming. The roaming service is one of the options, and you can use it by paying a small daily basic charge. ”As described in the above, costs will be incurred each time you use it, but if you sign a roaming contract, other businesses It is possible to receive the service of the person

[0005]

However, conventionally, the user cannot select the control information to be used in order to receive a desired service in an area where a plurality of control information are present.

[0006] For example, if the control information of a business operator who has a basic contract and the control information of an unusable business operator who does not have a roaming contract are captured, even if the user wants to make a call, a call is made. It did not always select the possible control information.

An object of the present invention is to provide an apparatus capable of surely receiving a user's desired service in an area where a plurality of pieces of control information can be captured and which is capable of automatically selecting a cheaper line. It is in.

[0008]

In order to achieve the above object, the present invention combines a function of recognizing a plurality of pieces of information of a service area currently existing and a function of recognizing / identifying an operator by the captured information. , The mobile communication terminal itself has been improved to select the most suitable service according to the priority set by the user from a plurality of information.

[0009]

In the present invention, by selecting the optimum information from the plurality of information by the above means, the user can be more surely
In addition, a cheaper service can be provided.

[0010]

Embodiments of the present invention will be described below with reference to FIGS.

FIG. 1 is an explanatory diagram showing the operation of the mobile communication terminal of the present invention.

In the figure, 101 is a mobile communication terminal capable of recognizing information of a plurality of mobile communication networks, 102 is a service area of a business operator A, 103 is a service area of a business operator B, 104.
Is an area where the areas 102 and 103 intersect and can receive both services, 105 is a wireless base station of the area 102, and 106 is a wireless base station of the area 102.

In FIG. 1, it is assumed that there are two business operators / areas provided by the mobile communication network: business operator A / service area 102 and business operator B / service area 103. It is not limited to.

Normally, the radio base station always transmits control information including an area ID indicating its own operator / area via the control channel, and the mobile communication terminal is powered on. In this state, it becomes possible to capture control channels transmitted from a plurality of radio base stations and analyze the information of the operator and the area by the area ID included in the control information transmitted from each radio base station. There is.

For example, in FIG. 1, the radio base station 105 transmits control information indicating the area 102, and the radio base station 106.
Is transmitting control information indicating area 103. Also,
The mobile communication terminal 101 includes an area 102 and an area 103.
Since it is located in the area 104 where and intersect, it can be recognized that the user is in the area 104 where both the control information indicating the area 102 and the control information indicating the area 103 can be captured and analyzed to receive both services. .

As described above, in the mobile communication network in which the mobile communication terminal operates, there may be an area where a plurality of control information exists. The plurality of pieces of control information are not limited to a single company, and information of a plurality of companies may be mixed.

Generally, in a mobile communication system, when a line contract is established with a certain operator and the station is opened, basically, it can be used only in the service area of the operator who has made the contract, and the services of other operators. Cannot be used in the area. However, with an optional contract, it can be used in the service areas of other companies with which it is affiliated (roaming contract). In this case, it is possible to receive services from a plurality of different businesses. However, conventionally, a user who is in a situation of receiving services from a plurality of businesses cannot arbitrarily select a service (business) to be used, which causes various problems.

[0018] For example, even if the control information of a business operator that does not have a roaming contract is captured, it cannot be used.
In addition, problems such as roaming charges and call charges will occur. When using the service area of another business operator that has a roaming contract, a "roaming charge" is added when calling in the service area of a business operator that has a basic contract.
Also, the call charge changes. Therefore, at points where service areas of different businesses coexist (points at which businesses other than the basic contract can be received), unnecessary costs may occur.

Further, the additional services such as the "transfer service" cannot be operated outside the service area of the business operator who has signed the basic contract.

Therefore, in the present invention, by automatically selecting the service area to be used in the area where a plurality of control information can be captured, the service desired by the user can be more surely received, and the line is cheaper. Is automatically selectable.

For example, in FIG. 1, the mobile communication terminal 101
Recognizes that it is currently in the area 104 where both the control information of the business operator A and the control information of the business operator B can be captured.
At that time, the mobile communication terminal 101 stores in its own storage device that the mobile communication terminal 101 has a basic contract with the business operator A and is open, and has no roaming contract with the business operator B (10).
7) The control information of the business operator A is automatically selected based on the conditions.

The configuration and processing flow of the mobile communication terminal 101 for realizing the operation of this embodiment will be described below.
