Especially when a charging system differs from kinds of roaming, the convenience is much more enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio communication device capable of confirming whether a user is at a base station home.

[0002]

2. Description of the Related Art In recent years, purchasers of wireless mobile communication devices such as portable wireless terminals have been increasing more and more. For example, US C
DMA (CodeDivisionMultipleA)
In the case of a base station employing a cellular system, a wireless mobile communication device under the jurisdiction of the base station has an ID number on the base station system indicating that the base station is under the jurisdiction of the base station according to a contract with the base station. (Hereinafter, referred to as “system ID”), and is in “HomePosition” when under the jurisdiction of this base station. If the wireless mobile communication device is out of the jurisdiction of the base station given the system ID, for example, if the wireless mobile communication device is physically away from the base station and cannot be reached by radio waves from the base station, The communicator is said to be roaming ("roaming" means wandering). In the roaming state, the billing system usually changes. In other words, performing communication within the jurisdiction of the contracted base station is advantageous in terms of charging.

Conventionally, as a method for notifying a user of the roaming state of such a wireless mobile communication device, there is an LCD display.

For example, in a case of a cellular system as shown in the area conceptual diagram of FIG. 15, it is considered to inform a user of a roaming state. In FIG.
"ID" means a system ID which is ID information for specifying a base station. In the example shown in the figure, this entire area is divided by a plurality of base stations, and i, j, k and m are assigned to the respective divided areas as SIDs.

FIG. 16 is a flowchart showing a roaming state determination operation of the conventional wireless mobile communication device.

As shown in the figure, first, the power of the wireless mobile communication device is turned on (step 1701). A system scan is performed simultaneously with the power-on, and if a channel having a certain electric field strength is found, the wireless mobile communication device locks to this channel (step 1702). Also, with the power-on, the communication device receives a downlink notification information message from a base station that is in charge of a certain area of the communication device, and receives SID _B , which is the SID of the base station, included in the message (step 1703). ). This received ID information, ie, SI
And D _B, the home SID information of the wireless mobile communication device SI
Then, a comparison is made with D _# (step 1704) to determine the roaming state. This comparison is performed by verifying that “SID _B = SID _Μ ” (step 1705), and determining “Yes” to determine the non-roaming state and “No” to determine the roaming state. When this comparison is completed, the standby process is continued after displaying the above determination result (step 1706).

In the prior art, when displaying the above determination result, a method has been adopted in which roaming or non-roaming is informed by the "ROAM" icon or indicator.

This conventional method is based on the assumption that the ID information from the base station is only the SID. The roaming determination is made only by determining whether the ID matches the home SID of the mobile station, and the determination result is displayed on the LCD display. It was possible to notify the user without any problem simply by displaying the message.

However, in addition to the SID, the NI
D information may be broadcast. Here, "NID" is an ID for specifying a network in which the own device is registered.
This information is broadcast as an ID obtained by further dividing the SID. The NID roaming state refers to a state outside the control of the registered network. Thus, when the base station broadcasts NID information in addition to SID,
Roaming status includes SID match and $ ID
There are four types: match, SID match and NID mismatch, SID mismatch and NID match, SID mismatch and NID mismatch. In this regard, in the conventional method, there is only one type of display in the roaming state. Even if is turned on, there arises a problem that it is difficult to determine which of SID and ΝID does not match.

[0010] In particular, when the charging system is different depending on which of the above four states, it is extremely disadvantageous for the user not to know the roaming state accurately. In addition, even if they are in the same roaming state, if they are in the network in which they are registered (the above-mentioned roaming states of SID mismatch and NID match), a system that can use some special function is used. In such a case, the fact that the user cannot know the roaming state accurately means that the system cannot be effectively used.

[0011]

As described above, in the conventional wireless mobile communication device, as described above, since the roaming notification method is one type using the display device, the user must use the SID.
In addition, there is a problem that it is not possible to easily determine which of the NID and the NID is in the roaming state, and it is not possible to check the fee system or the service specific to the base station.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and a moving device capable of easily confirming the SID and #ID roaming states by adding or changing a display for displaying the roaming state. An object is to provide a wireless communication device.

Another object of the present invention is to provide a mobile radio communication device capable of confirming a roaming state by a user function setting operation.

Think to inform. In the figure, “SID” means a system ID which is ID information for specifying a base station, and “NID” means a network ID which is ID information for specifying a network served by a wireless mobile communication device. .
The base station (not shown) provides SID
, And NID are broadcast. On the other hand, inside each wireless mobile communication device (not shown), SID and NID are registered as home ID information by contract with a base station. In the example shown in the figure, this entire area is divided by a plurality of base stations, and i, j, k and m are assigned to the respective divided areas as SIDs. In the area where SID = i, there are three networks whose NIDs are referred to as o, u, and t. SID = j
, There is one network named NID = t, and in the area SID = k, one network named NID = w.

At this time, the SID issued from each base station

Also, as shown in FIG. 9, if the wireless mobile communication device is in the area of SID = j and NID = t
If the wireless mobile communication device is located within the area, the ID information received by the wireless mobile communication device from the base station is (SID _B , NID _B ) =
(J, t). On the other hand, home I of the wireless mobile communication device
Since D is (SID _M , NID _M ) = (i, t),
The SID _M of the mobile device does not match, and the ΝID _M matches. In such a case, the roaming state is determined to be C (step 410) and displayed on the display as shown in FIG. 10 (a) or (b). Here, “S-ROAM” shown in FIG. 6A and “System-System” shown in FIG.
“Roaming” indicates that roaming has occurred in “System”.

Also, as shown in FIG. 11, if the wireless mobile communication device is in the area of SID = k and NID =
If the wireless mobile communication device is in the area w, the ID information received by the wireless mobile communication device from the base station is (SID _B , NID _B )
= (K, w). On the other hand, the home ID of the wireless mobile communication device becomes _{(SID M, NID M) =} (i, t) because it is, the mobile device SID _M and NyuID _Micromax both mismatch. In such a case, the roaming state is determined to be D (step 411) and displayed on the display as shown in FIG. 12 (a) or (b).

The standby process is continued based on the above-described determination of steps 408 to 411 and the display of the determination result (step 412).

As described above, a combination of two types of roaming states, SID and NID, is introduced, and the area ID of the base station is
Is compared with the home ID of the wireless mobile communication device, the roaming state of the wireless mobile communication device is determined, and the determination result is displayed on the display 3. Therefore, the user can select either the SID or the NID. It can be easily determined whether or not a roaming state has occurred.

2). If no communication connection has been made, it is checked whether a user function has been set (step 80).
3). Here, the “user function” includes a function of causing the wireless mobile communication device to display a roaming state based on a request from the user. For example, "Function" means a function that takes two arguments (called "digits") immediately afterward and displays the roaming state of the mobile communication station represented by these two digits.

When there is a display request from these users due to the function setting, the roaming status is displayed on the display as shown in FIG. 14 (a) or (b), for example, according to each required function (step). 804). After the end of the display or when the user function setting has not been made in step 803, the process returns to step 802. On the other hand, if the communication connection process occurs in step 802, the access process is started (step 805).

As described above, in the second embodiment,
In addition to the first embodiment, the roaming state is displayed in response to the user's function setting operation, so that the user can arbitrarily check the roaming state.
