The present invention relates to a system that effectively uses communication channels by moving to an area where communication channels exist and transferring calls.

However, if call demand temporarily increases within a specific area, a line cannot be secured and the call is lost, and even if there are free lines in other areas where calls can be made, they cannot be used, and there is not enough Lines were not being used effectively.

As described in Publication No. 6334, if mobile stations are located in coverage areas adjacent to each other, even if the field strength level is at its maximum, if there is another base station that can communicate, the control channel of that station will be used. There is a method for distributing calls concentrated at a specific station to other stations by making calls and responding to calls using a station.

かった。[Problems to be Solved by the Invention] In the above method, a base station specifies the electric field level of another base station with which it can communicate. Therefore, even if a telephone line is available, it is not necessarily utilized effectively unless the electric field level condition is met.
【０００５】本発明は、移動局が位置登録エリア内に空
きチャネルがないために生する呼損をできるかぎり減少
させるチャネル割当て方法を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a channel allocation method that reduces as much as possible call losses caused by the lack of free channels within a mobile station's location registration area.

す基地局を通話可能基地局とする。[Means for Solving the Problems] The above purpose is to create a base that can communicate autonomously and decentrally by having each base station notify the blockage status of its own communication channel, and having the mobile station itself judge whether it is possible to communicate. This can be achieved by having the station selected. Specifically, each mobile station receives notifications from each base station in advance, and selects a base station that satisfies the condition that the received electric field strength is a certain value or more as a base station capable of making calls.
【０００７】発呼時に移動局はそれを検知することによ
って、他の通話可能な基地局に移行し、発呼をすること
により通話チャネルを有効に活用できる。[0007] When a mobile station detects a call, it can move to another base station capable of making a call, and make effective use of the communication channel by making a call.

能性が高くなる。[0008] When a call is received, even if there is no free communication channel in the location registration area, the base station sends an incoming call request signal and a request signal for reregistering the location to another area, or sends a call request signal to another base station that is available for communication. etc. are specified, increasing the possibility of being able to make a call.
【０００９】また、自動車電話と違ってひとつの基地局

Furthermore, if a line is in a blocked state, there is a high possibility that the subscriber density in that area exceeds the allowable capacity. Therefore, the calls can be distributed by having the mobile station where the call occurred re-register its location in another area.

られる。[0014] Each mobile station (hereinafter referred to as MS) has one BS, for example.
Register your location only. At that time, for example, register one or more callable BSs that are considered to be callable when the received field strength is above a certain value, and register them with the management station through the location registration BS2.
02. At this time, the received field strength of each BS or the order of its strength may be sent together. It is also conceivable to set a maximum number of callable BSs that can be registered for each mobile station.

２０６となる。[0017] If it is confirmed that the TCH is not available, the MS searches 205 for another BS that is available for communication (for example, the received field strength is above a certain value) and that has an available TCH. Here, if there is no BS that satisfies the conditions, the call is lost 206.

ＢＳを移行先とする方法等がある。[0018] If a BS that satisfies the conditions exists, there are several methods for determining the migration destination. For example, a method that selects the one with the highest received field strength from among all the BSs that meet the conditions as the migration destination. In order to shorten the time required for this check, there is a method in which the first BS found after starting the check that satisfies the conditions is set as the migration destination.

A call request is made using CH, etc., and after a series of operations, the call is transferred to TCH and a call 207 is started. Location registration is also performed before, after, or at the same time as this call request. At this time, the BS notifies the management station of the call request and updates the home memory.

If the CH is vacant, a wired line is directly connected to the location registration BS, and a call 208 is made through the location registration BS.

If there is electric field strength data, the strongest BS among them is selected as the migration destination. If there is no field strength data, the transfer destination is appropriately determined from among the available BSs.

The frequency where the ID, CCH, etc. exist, the time slot number, etc.) are specified 213 to the MS via the location registration BS. Upon receiving this, the MS transmits 214 a confirmation using the CCH or the like of the designated BS. At this time, the BS notifies the management station of the confirmation, updates the home memory, and switches the wired line to the destination. Thereafter, after a series of operations 211 using the CCH of the new BS, the communication shifts to TCH, and a call is started 212.

ＢＳの中から適当に移行先を決定する。[0026] As a third example, the management station selects a BS that currently has a vacant TCH from among the above callable BSs,
If there is electric field strength data, the strongest BS among them is selected as the migration destination. If there is no field strength data, the transfer destination is appropriately determined from among the available BSs.

要となる。Thereafter, the management station instructs the destination BS to send information such as the frequency and slot number of the currently vacant and usable TCH to the management station. however,
If the management station already has this information, this operation is unnecessary.

Ｓを待機させる。[0028] Then, information on the destination BS (BSID, frequency where an empty TCH exists, time slot number, etc.) is specified 215 to the MS via the location registration BS. At the same time, the management station connects the wired line to the destination BS and
Make S stand by.
【００２９】ＭＳは位置登録ＢＳからの情報を受けて、

However, in this case, the location registration during standby is performed without regard to whether there is a vacant TCH or not, and registration is made to the BS with the strongest received electric field strength.

The CPU 401 causes the radio section 402 to sequentially receive each frequency on which the BS is thought to be broadcasting, and stores the IDs and received field strengths of BSs whose field strengths are above a certain level that are thought to be possible to talk to in the memory 403 for callable BS memory. 4

Separately, callable base stations that are thought to be able to make calls with a fixed received field strength are registered in advance with the management station via the location registration base station, and each base station checks the availability of its own call channel. In a wireless system that has multiple channels such as a control channel that can broadcast and multiple call channels, registration of the mobile station is required when the mobile station is called through the base station and the management station that controls the base station due to an incoming call. When there are no base stations with vacant communication channels in the area, the management station sends an incoming call request to the base stations in the location registration area of the relevant mobile station, and IDs of base stations with vacant communication channels in other areas. The base station within the location registration area of the relevant mobile station transmits the incoming call signal notified by the management station to the relevant mobile station and the available base stations with free communication channels in other areas. The ID is notified, and the mobile station receives it and sends an incoming call confirmation signal to the designated base station, and when the designated base station receives the confirmation signal, it positions the mobile station as having jurisdiction over its own area. A call channel allocation method characterized in that the management station secures a free call channel by registering the call and transferring the incoming call to a new area.
