Abstract

PURPOSE:To decrease undesired process at a control station and to improve the quality of service for the connecting time, etc., by adding the idle channel information to a control signal and transmitting them at a base station having no idle channel. CONSTITUTION:A service area 1 is formed with plural minor line zones 2 which are sufficiently capable of transmission with the transmission power of a mobile station. A base station 3 is provided for each zone 2, and at the same time a general control station 4 is set for the area 1 as a whole. The station 4 uses the common control channel of each zone 2 to perform the transfer of the control signal to the mobile station and controls the mobile station. Then the station 3 relays the control signal 9 to the station 4 together with the idle channel information 10. At the same time, the station 4 performs a control so as not to select the station 3 having no idle channel when the zone 2 where the mobile station is located.

Description

DETAILED DESCRIPTION OF THE INVENTION In this service area, the service area is composed of a plurality of small #1lIiI zones that can be sufficiently reliable with the transmission power of the mobile station, and base stations are installed in these small fish line zones.
In addition, a control station has been installed that broadcasts IIJ # for the entire service area at once.
Regarding the F#41Im system that performs vIIM+ for mobile stations using the common mu-koji channel vr in the S zone, in particular, the base station sends the 11114 Ill signal from the mobile station on the IIJ channel to the control station. It concerns the method of relaying.

<Movement s11100 General Tome> First, in order to make the appearance of this invention into a product, the above movement, 111
Figure 1 shows the success and failure of zone #l in the 1+1 system.A plurality of small fish line zones 2 are divided and arranged in one service area, and each small fish line zone 2 has 2#&i. Local station 3 has been emptied. The entire area is controlled by a moving shaft 44. A fixed transmission path 6 is provided between each base station 8 and the control station 4.
Suppose that - is connected by. In the example of 帛l-, service area 1 is ^.

Alternatively, for the VFIJ Koji channel f, it is conceivable to transmit data with a power as high as the amount of light required to service the entire area of the telecommunications and business area from 4 to 50 degrees.

System #4 in the transfer 11J Muen Banshiki that was lost in this way
An example of a mobile station originating from a mobile station using the ILI talk channel system in 4 will be described below. The mobile station located in the small radio zone 2 of station A makes a call and makes a friend.The mobile station N6 uses the common control channel f, (7) to transmit the call number t% between each radio base. In 3, the 41111I channel f1's swi reception system will be installed, and the swi reception from the mobile station will be
? I am now able to receive the scar signal.

Therefore, the calling signal from the mobile station in small wireless zone 2 is
What about base station 8? i! 1114 received between bases 3 of Jvb, B, and C is also large, and now any base JI6
Assume that calling signals are received in 3. ・These calling signals are transmitted to the control station 4 via the fixed transmission line 5 ・Control @
At station 4, three 4 base stations 3 will simultaneously issue Iγ calls (receive No. 1), but in order to determine which small fish the RI Sakura 1 station will It is essential to know the power transmitted from the two islands of the same zone, 65, and for this reason, each base Jt
Measure the received electric field level when receiving a % call signal in III43, and check whether it is warped or not. ll1111 [Transmit to control unit 4, l
The IJ control station 4 compares the electric field level of each base station 3ρ, etc., and determines that there is a mobile station in zone 2, which corresponds to the base 43 where it is the maximum, and locates it in that zone. Select an empty channel from among the filled channels.
Select and do it [I#1 will be added to Keyaki Kanma.

In the above example, since the transferred station is shielded within the Oguro-Zone A, the received electric field level at base 43 is naturally larger than that at 3 between bases B and C, and there is no difference in the control interval. Zone A
II! is assigned to the mobile station. l#I channel designation ttii. However, with the above explanation, the base of ^ is 3117
If there are no supercharging channels in 11 and 9, then if all communication channels are communication channels, then 劃IIIIN6
In 4, if the received electric field level from each base JlII1 station 8 is the next highest between the bases in ^, and the received electric field level is the received electric field level of the quality equivalent to the amount of light required for communication, then ? I'm going to go to the place where the small amount zone ^ and the small sIIM zone (Bl is C) and the unrelated zone of the lumpy territory wrinkle overlap. When J is pregnant, etc., select the iIi channel kg from the local channels distributed in the 10A Hato Sa, and make a sound to specify the communication channel to the mobile station. If N6 does not exist, use 111J Goten 4 against Yaguri Doson! L! lk! It is common for the mobile station to send out a black message on the mother-in-law channel and let the mobile station know that it cannot use n* to the subscription form, etc.

With the above explanation, in the signal relay of the base station 80 control channel, conventionally all the communication channels of JK location #168 are 92%, and the signal from the mobile station is transmitted between bases 8 [to simply relay, the mobile station F9T exists. If the base station in the zone does not have a free communication channel, control 1J14 performs control signal [After receiving the control signal, it performs processing that is originally unnecessary in this case, such as selecting between bases and creating a free communication channel, as shown in the control #+pus above. I have to do this and also other people! There are drawbacks such as the time it takes to repair a filled base station, which reduces the number of subscribers that can be used at the control station, and also reduces the Davis product purchase price due to the service life time. Rarely.

<Overview of Umei> This transmission is performed by adding t*Wt- of an empty communication channel to the IIIJ number relayed to the side # station by that base station when there is no supercharging channel between bases. The purpose is to reduce the originally unnecessary processing space at the TolJ# station and to improve the service life in terms of continuous time, etc. . tl
In lJ Okono, it is possible to determine in which zone the stick is present, but between bases that do not have a 9-way channel, it is possible to make a small judgment by not using it from the beginning. By sitting next to each other without doing the treatment, the treatment time will be shorter.

It is possible to compare the received electric field level from each base based on the current channel information lO, but for base stations without communication channels, it is difficult to compare from the beginning.
＜Cine processing which is possible is omitted, and the connection time when connecting to another base station is also shortened.
If the control number 41 is relayed only from 70 bases JlllJ11, the free call channel will be immediately cleared.*
It is possible for the uiu 4 to transmit to the mobile station and notify the subscribers of the mobile station that the congested channel is congested.As explained above, the base station By adding information about 9 channels to the control signal that is necessary for continuous operation, the number of call transfers at the station is reduced, and the number of subscriber numbers is increased compared to the conventional system. One advantage is that the connection time during calls is reduced by 4.
