Abstract

PURPOSE:To omit the processing for duplicated position registration in a duplicated talking area by providing a table of peripheral radio connection device to a radio line controller. CONSTITUTION:When a user having a cordless telephone set 24 moves from an area 23e to an area 23a, position information different from position information in a memory is informed from an area 22a. Then the cordless telephone set 24 recognizes the movement of itself and applies position registration to the radio line controller 21 via a radio connection device 22a. In such a case, the radio line controller 21 sends the acknowledge of the position registration to the cordless telephone set 24 and sends the information of radio connection devices 22b, 22c therearound connectable obtained from the table. The cordless telephone set 24 stores the radio connection devices 22b, 22c in addition to the radio connection device 22a to store the device name located therearound connectable without position information informed sequentially from the device 22b, 22c and it is not required to give position registration request to the devices 22b, 22c.

Description

[Detailed Description of the Invention] (Field of Application in +JY Industry) The present invention provides a method for reducing location registration trouble in a mobile communication system in which the wireless zone and location registration zone coincide and there are many relatively small wireless zones. It is related to.

(Prior Art) FIG. 2 shows the configuration of three mobile communication systems to which the present invention is applied.

Here, there is a wireless zone (calling area) and a location registration zone.
・Since the cordless telephone is moved from its permanent location in call area C to another call area B, this system requires location registration. Location information is obtained as follows. The cordless telephone 1 identifies the location information reported for each wireless connection device (for example, reports the own connection device 10), and compares it with the location information stored in the memory.
If the location information is different, the cordless telephone 14 automatically registers the location with the radio line control device 11 via the wireless connection device that notified the different location information, here +2b. When located between call areas B and C, the cordless telephone 14 receives location information from the wireless connection device 12c and performs location registration again.

(Problems to be Solved by the Invention) In other words, in the above technique, if there are multiple call areas, the cordless telephone 14 will perform position information as many times as there are overlapping call areas.

This includes a cordless telephone 14, a wireless connection device 12, and a wireless circuit! ! I! There is a drawback that the control device 11 has to perform the process for location registration many times.

An object of the present invention is to reduce the number of location registrations by utilizing the overlap of the radio zones in a system composed of a large number of small radio zones, and to reduce the processing load of the radio line control device.

(The first step to solving the problem) The present invention is a mobile communication system in which areas such as premises often overlap, and the present invention provides wireless co-operation control using a double that stores the relationship between connections 1 and 7 communication area phases tl- in the system. The most important features of the device are: That is, in premises such as buildings, the structures and shapes thereof are complex and irregular, making it difficult to configure regular calling areas. Also, the calling areas are small and numerous. Therefore, automatic 11 (multi-station control method like telephone cannot be adopted, and simple call area and control area can be set. Also, in order to make the radio waves reach all the way), Call area i
A nine-duty call area configuration method is adopted. Moreover, the entire calling area in this system is limited to within one building, etc., so it is complicated, but management is easy. Therefore, in advance, measure the call area of the connecting device in this system, and confirm whether there are multiple calls in the same area and whether the call is connected.
ii: By measuring the surrounding wireless connection devices,
Is it possible to create and manage a table of surrounding wireless connection devices?
'f rib.

(Embodiment) FIG. 1 is a diagram showing the configuration of a mobile communication system to which the present invention is applied, in which 21 is a radio line control device, 22a to 22e are wireless connection devices, 2]a to 23C are call areas, and 24 is a cordless phone.

In FIG. 1, the wireless connection devices 22a to 22e broadcast position information ffj, ie, location information including an identification signal of the wireless connection device, under instructions from the wireless line control device 21. The notification may be transmitted sequentially using radio waves with a different frequency for each wireless connection device, or may be sequentially notified in a time-division manner using a common frequency.

The cordless telephone 24 stores a plurality of connectable location information, and compares it with the location information reported from 22a to 22c.If the location information differs from the content stored in the cordless telephone 24, In this case, the cordless telephone 24 automatically requests the wireless connection device that has notified the location ++'i 'k to register the location.At this time, the wireless connection device that has received the location registration confirmation transmits the identification (Ii) of the cordless telephone to the radio line control device 21 = 1 ((The line line control device 21 transmits the identification number Ii to the wireless line control device 21 = 1). A cordless electrician, along with a daple;
From 1L machine 24 (, when Uaki of toy record was available, 111 was replaced with the new Q Iku 111 Moth. Furthermore, in the present invention, 22a to 22c jj M line Thorn's call 1-Ir
rifTh area and surrounding areas that overlap with the area (1 Measure the communication area of the device, and find the relationship of the area in-phase lI', for example, In complex r-,
Click to select nearby wireless connection devices with overlapping call areas. The peripheral device table Table 1 is calculated using ++7NJ represented by the identification signal of the wireless connection device.

(Margin below) Table 1 Peripheral device table The operation of this method will be explained.

When the cordless telephone 24 is located in the calling area 23e, as shown in Table 1, it stores 22d as a peripheral device in addition to the device 22e in its own calling area as a wireless connection device to be connected. At the same time, the user receives the location information broadcast by the devices 22e and 22d, and confirms his or her location. Here, the user with the cordless telephone 24 is in the area 23.
When moving from e to 23a, position information different from the stored position information is reported from 22a. Therefore, the cordless telephone 24 recognizes that it has moved, and registers its location with the wireless line control device 21 via the wireless connection device 22a. At this time, the wireless line control device 21 not only transmits a confirmation of location registration to the cordless telephone 24, but also transmits information about connectable peripheral wireless connection devices 22b and 22c obtained from the table of Table 1. By storing 22b and 22c in addition to 22a, the cordless telephone 24 can store the names of peripheral devices that can be connected without waiting for the position information sequentially notified from 22b and 22c. This eliminates the need to make multiple location registration requests.

(Effects of the Invention) As explained above, by having the wireless line control device have a table of nearby wireless connection devices, there is an advantage that redundant location registration processing in overlapping call areas can be omitted.
