This also enables automatic blocking control of the communication channel in the satellite zone. Furthermore, the common control unit 5-3 provides a queuing queue for outgoing calls in order to prevent the satellite system from being occupied by incoming calls during the busiest times and unable to process outgoing calls from mobile stations located in the satellite zone. If there is a channel in the incoming call processing that is not in a call state, it accepts the outgoing call in the satellite zone and registers it in a waiting queue. Has a function of performing a calling process according to.

FIG. 5 shows the structure of the queuing queue. FIG.
The medium waiting time indicates that the mobile station is entitled to the calling process up to the indicated time. If there is no idle relay radio device even after the limited time has passed, the common control unit determines the mobile station. The registration of the outgoing call request is deleted from the queue and a call rejection signal is sent out via the control channel.

Thus, the relay line control device 5 is configured to be able to output a transmission start command for establishing an uplink communication line in the home zone. In this case,
The trunk line control device 5 is provided with the queuing queue buffer as described above for transmitting a mobile station located in the satellite zone, and is configured to perform a waiting transmission process.

By the way, in the relay radio apparatus 4, when the relay radio section in which the transmission mode is set transits to a specific call processing state of the mobile station located in the satellite zone, the relay radio section in the standby mode is set. The setting of the radio unit to the transmission mode is changed to handle a new transmission request in the satellite zone. In the relay wireless device 4, when the number of relay wireless units that can be newly used for outgoing / incoming processing becomes one, the mode of the wireless unit is set to the outgoing / incoming mode.

Further, in the relay radio apparatus 4, the relay radio unit, which has set the incoming mode or the outgoing / incoming mode, identifies the control channel of the system that performs the incoming call processing in the home zone. In this case, the system number performing the incoming call processing is broadcasted by the broadcast signal of the downlink control channel of the system.

Further, in the relay radio apparatus 4,
A downlink control channel signal received by the dedicated control channel receiving device 4-R for identifying a control channel of a system in which the relay radio unit in which the incoming mode or the outgoing / incoming mode is set performs incoming processing in the home zone. , The system performing the incoming call processing is determined, and the relay wireless unit is assigned to the system.

Further, the trunk line control device 5 is capable of restricting the transmission of calls from mobile stations located in the satellite zone in all of the systems in the home zone that can be accessed by the satellite system. When a predetermined number of channels are in use, a control channel for the satellite zone is used to transmit a transmission restriction signal.

When it is confirmed that a loop check response signal has been received from a mobile station located in the satellite zone, the trunk line control device 5 transmits the loop check response signal to the relay base station radio unit that has received the loop check response signal. It is configured to activate a transmitter of a corresponding relay radio unit. In addition, a call response signal for a call signal from a mobile station located in the satellite zone is locally returned by the satellite system, and in parallel, a call is transmitted in the home zone to a relay radio unit set exclusively for call processing. It is configured to transmit a call signal.

When a response signal is returned from the mobile station located in the satellite zone to the line control device 2 in the home zone, the signal transmitted by the line control device 2 in the following sequence is transmitted to the relay radio device 4. Is received without transmitting a response signal, the trunk line controller 5 restores the relay radio unit and the corresponding relay base station radio unit.

If the system that actually receives the incoming signal from the circuit switch 1 is different from the system to which the mobile station to which the incoming call belongs belongs, the channel designation incoming signal for this mobile station is sent to both systems. To the control channel. With the above configuration,
The relay line control device 5 creates a control signal in the satellite zone based on the data of the control channel signal in the home zone received by the relay wireless device 4, and uses the control signal (C-CH) for the satellite zone to generate the control signal. To the mobile station. Transmission from a mobile station located in the satellite zone is performed via a control channel for the satellite zone. From the viewpoint of the mobile station, there is no difference from the transmission operation sequence in the home zone.

The relay line control device 5 converts the transmission signal received via the control channel in the satellite zone into the transmission signal format in the home zone, and transmits the relay radio signal of the relay radio device 4 designated for transmission. Part 4-j
To perform a calling operation in the home zone. Each radio unit 4-j of the relay radio device 4 is viewed from the line control device 2 in the home zone in the same manner as a general mobile station,
In place of the mobile station located in the satellite zone, the mobile station operates as if transmitting in the home zone. That is, the radio unit 4-j of the relay radio apparatus 4 has the function of a mobile station in which the subscriber number of the mobile station and the ID number can be rewritten as necessary. In the control channel of the system of the commanded home zone, each is in a standby state.

At that time, the trunk line control device 5 designates which radio unit of the relay radio device 4 is to be used for transmission processing and which radio unit is to be operated for reception processing. The wireless unit 4-j of the relay wireless device 4 can access all systems (SYS1 to SYS-N) in the home zone, and can configure a wireless link using all communication channels.

Therefore, the relay radio apparatus 4 spatially exchanges the radio line in the home zone and the radio line in the satellite zone, and concentrates the radio channels in the home zone up to the required number of radio channels in the satellite zone. By adopting such a relay system, the switching control station 100 in the home zone and the relay system are loosely coupled via a wireless line, so that the service quality of the home zone can be improved even if the satellite system is introduced. It is possible to keep the street.

Since the complete line group can be switched between the satellite system and the home zone system at the level of the radio line, the mobile station located in the satellite zone provides a highly reliable call service. Can receive. Further, the satellite system will be described in detail. In the satellite zone, as described above, the number of communication channels L and the number of control channels are 1, and the communication service is provided to the mobile stations located there by the multi-channel access method of the common control channel method similar to the home zone. Provided.

Then, the communication channels 1 to L of the relay base station radio device 6 are connected to the radio units 4-1 to 4-L of the relay radio device 4 via the relay line control device 5 on a one-to-one basis. Have been. As described above, each radio unit 4-j of the relay radio device 4 has a function equivalent to a mobile station, and when a system to enter a standby state is designated by the relay line control device 5, the radio unit 4-j The standby state is automatically entered in the control channel.

Then, each radio section 4 of the relay radio apparatus 4
j operates as a mobile station having the subscriber number and mobile station ID number designated by the trunk line control device 5. Therefore, the transmission from the mobile station located in the satellite zone appears to the line control device of the switching control station as if it originated from the mobile station located in the home zone.

On the other hand, when a call arrives at a mobile station located in the satellite zone, a radio unit designated for call reception processing by the trunk line controller 5 in the relay radio apparatus 4 arrives like the mobile station. Enter the call processing sequence. When receiving the incoming signal from the incoming call processing relay radio unit, the relay line control device 5 controls the control channel (CC) of the relay base station radio device 6.
H), an incoming signal is sent out, and a communication channel radio section of the relay base station radio apparatus 6 corresponding to the call processing relay radio section is notified. The relay radio unit designated for incoming call processing shifts to an incoming call processing sequence in response to incoming signals for all mobile stations. At this point, a channel of the relay base station radio apparatus 6 covering the satellite zone in one-to-one correspondence with the incoming call processing relay radio section has been secured.

Then, the relay line control device 5 applies the above-described five operation modes (modes 1 to 4) to the wireless unit 4-j of the relay wireless device 4 which is not being used for a call at that time. Set the mode 5). For example, mode 1
When the relay radio unit, which is set to (for transmission processing only), relays the transmission signal of the mobile station located in the satellite zone and makes a state transition to the transmission processing sequence, the relay line control device 5 sets the mode to The relay wireless unit in the 4 (standby) state is changed to the mode 1 to handle a new call request in the satellite zone.

When the number of vacant relay radio units becomes one, the relay line control unit 5
Is set to mode 3 (for both outgoing / incoming calls). The method by which the trunk line control device 5 determines which system control channel signal in the home zone should be received by the relay wireless device 4 is as follows. (1) When the circuit switch 100 of the switching control station is a public network (PST)
N) When all incoming calls to the mobile station are connected to a specific system (for example, system 1) (see FIG. 13).

As shown in FIG. 13, the trunk line controller 5
Sets the wireless units of the relay wireless device 4 in all of the modes 1 to 4 in a standby state in the specific system. Therefore, all incoming calls to mobile stations located in the home zone and the satellite zone are made on the communication channel of the specific system. The outgoing call of the mobile station located in the satellite zone is also performed on the communication channel of the specific system.

Further, the trunk line control device 5 designates the radio section of the relay radio device 4 in which the mode 2 and the mode 3 are set to enter the standby state on the control channel of the specific system for performing the above-mentioned incoming call processing. Then, the relay line control device 5 determines the system to which the relay radio unit to which the mode 1 and the mode 4 have been set belongs, as follows.

All the mode 1 and mode 4 relay radio sections belong to the specific system that performs the above-mentioned incoming call processing. That is, all the relay wireless units in modes 1 to 4 belong to the same system. In this case, the call service for the mobile station located in the satellite zone is concentrated on a specific system in the home zone. Mode 1 and mode 4 relay radio sections are distributed and belong to a plurality of systems including the above-described specific system. This means that the transmission process from the mobile station located in the satellite zone is distributed to a plurality of systems.

In this case, all incoming calls to the mobile station located in the home zone are processed in the specific system irrespective of the system to which the mobile station belongs, and outgoing calls from the mobile station located in the home zone are: The processing is performed in the system to which the mobile station belongs. Also, when the circuit switcher 1 switches a specific system to another system, the relay wireless device 4 of the satellite system automatically accesses the system to be switched to, and performs the call origination / reception processing of the mobile station located in the satellite zone. Is to be performed.

(2) The case where the circuit switch 1 of the switching control station 100 connects the incoming call of the mobile station from the public network (PSTN) to a plurality of systems (see FIG. 3). First, the trunk line control device 5 detects a system that performs incoming call processing in the home zone, and controls the relay wireless unit in which mode 2 or mode 3 is set to belong to the system.

The method by which the trunk line control device 5 recognizes the system executing the incoming call processing in the home zone is as follows. The line control device 2 of the switching control station 100 uses the downlink notification signal of the control channel of all the systems in the home zone,
Notify the system number performing the incoming call processing.

At this time, the system automatically shifts to a system in which the relay radio unit set to mode 2 or mode 3 is performing a call reception process notified by a broadcast signal, and FIG.
As shown in the figure, a dedicated receiving device 4-R for receiving a signal of a downlink control channel of the system in the home zone is installed, the receiving process is executed from the contents of the broadcast signal, the system is known, and the trunk line control is performed. There is a method of notifying the device 5 and notifying the relay line control device 5 of a system number to be assigned to the relay wireless unit for setting mode 2 or mode 3 based on this information.

The system performing the incoming call processing is recognized based on the presence / absence of the normal incoming call processing signal transmitted on the downlink control channel of the home zone system. At this time, first, the control channel dedicated receiving device 4-R (see the chain line in FIG. 7) is provided for the system in the home zone, and the system receiving the incoming call processing signal is recognized. There is a method of notifying a system number to be assigned to a relay wireless unit that sets mode 2 or mode 3 based on this recognition.

Further, the control channel dedicated receiving device 4-R
There is a system in which only one system (see the solid line in FIG. 7) is provided to follow the system that transmits the incoming call processing signal among a plurality of systems, thereby always recognizing the system that is performing the incoming call processing. . In this case, in order to enable the following control, the order in which incoming calls from the circuit switch 1 of the switching control station 100 or the public switched telephone network (PSTN) to the mobile station are distributed to each system, and the radio channel within the system, (For example, from the youngest channel to the oldest channel), and data such as the number of channels of the system, which the relay line controller 5 has as a database.

Under the above conditions, the trunk line control device 5 specifies the system to which the relay radio unit for setting mode 2 or mode 3 belongs. Next, FIG. 8 shows an outgoing / incoming call connection procedure by the trunk line control device 5. In FIG. 8, for example, it is assumed that the relay radio unit 4-2 is set to the mode 2 (dedicated to incoming call processing), and is executing incoming call processing to the mobile station 7-α located in the satellite zone. I do.
In this case, access from the control channel (C-CH) (see FIG. 8) to the communication channel (S-CH No. 2)
FIG. 9 shows an incoming call processing control sequence including a connection to the service (see FIG. 8).

In FIG. 9, relay radio section 4-2
Has received a reception processing channel designation from the relay line controller 5, and in this state, when a broadcast signal is output from the channel controller 2-1-1 of the line controller 2, the relay signal is transmitted to the relay radio unit 4-1. And notifies this to the mobile station 7-α.
Thereafter, when an incoming call signal to the mobile station 7-α is issued from the circuit switch 1, the incoming signal is transmitted to the common control unit 2 of the circuit control device 2.
If the result of the test is "OK" and the result of the test is "OK", the channel control unit 2-1-1 of the line controller 2 sends a channel-specified incoming call signal (channel 1 of the system 1). As a result, the relay wireless unit 4-1 shifts to the channel 1 of the system 1.

Then, when the incoming call notification is notified to the relay line control device 5, the relay line control device 5
-2 and the communication section radio section 6 of the relay base station radio apparatus 6
-2 (communication channel S-CH No. 2), and the relay base station radio apparatus 6 sends a channel-designated incoming signal on this channel to the mobile station 7-α. As a result, the mobile station 7-α receives the S-CH NO. Shift to 2.

Thereafter, a loop-back check signal is sent to the mobile station 7-α, the mobile station 7-α issues a loop check response, activates the relay radio unit 4-2, and further transmits a loop check response. return. If the loop check is OK in the line controller 2, the line controller 2 sends a ring back tone to the line switch 1 and a call signal to the satellite system. When the mobile station 7-α responds, the ringback tone is stopped and the mobile station 7-α enters the call state.

Similarly, in FIG. 8, for example, the relay radio unit 4-L is set to mode 1 (for exclusive use of transmission processing).
It is assumed that the mobile station 8-β located in the satellite zone is performing transmission processing. In this case, the control channel (C
-CH) from the transmission command (see (1) in FIG. 8) of the transmission signal from the relay radio unit 4-L received from the communication channel (S
-CH NO. FIG. 11 shows an outgoing process control sequence including a connection to L) (see (2) in FIG. 8).

In FIG. 11, relay radio section 4-
L has received the reception processing channel designation from the trunk line control device 5, and in this state, when a callable notification signal is output from the channel control unit 2-1-1 of the line control device 2, the signal is relayed. The radio unit 4-1 receives the notification and notifies the mobile station 8-β. Thereafter, when the mobile station 8-β performs an outgoing call operation by an off-hook operation, a call signal is output from the mobile station 8-β. Then, a call response is returned from the relay base station wireless device 6, and a call instruction is issued to the relay wireless unit 4-L via the relay line control device 5. This allows
The transmitter of the relay radio unit 4-L is activated to send a call signal to the switching control station 100 side. Upon receiving this signal, the switching control station 100 returns a call response signal to the satellite system side, performs a test for making a call, performs a process for enabling the call, and then performs a process for enabling the call. To the channel designation call signal (S-CH @ m). As a result, the relay radio unit 4-L shifts to S-CH @ m and sends a channel-designated call signal reception notification to the relay line control device 5. In the trunk line control device 5, the relay radio unit 4
-L and the relay base station radio section 6-L, and the mobile station 8
Send a channel designation call signal to -β. Thereby, the mobile station 8-β communicates with the communication channel S- of the relay base station radio section 6-L.
CH NO. Shift to L.

Further, the mobile station 8-β is transmitted from the circuit switch 1.
To the mobile station 8-
issues a loop check response, activates the relay radio unit 4-L, and returns a loop check response. After that, the communication state is entered after a communication path setting command. FIG. 10 shows a call termination sequence of the mobile station 7-α located in the satellite zone.

In FIG. 10, when the talking state ends, the mobile station 7-α sends an end signal to the circuit switch 1 side.
Thereafter, the communication is terminated after waiting for a disconnection signal from the circuit switch 1 and restoring. Therefore, as can be seen from the incoming sequence to the mobile station 7-α located in the satellite zone of FIG. 9, the trunk line is received when the loop check response signal responding to the continuity check signal for the mobile station 7-α is received. The control device 5 activates the transmitter of the relay radio unit to establish the uplink communication line and relay the received loop check response signal.

As described above, when the transmitter of the relay radio section is controlled, the relay radio apparatus 4 does not suppress the transmission wave of the mobile station in the home zone when the zone where the mobile station is located is unknown. Incoming call processing can be executed simultaneously in both the home zone and the satellite zone. The mobile station 8-β located in the satellite zone of FIG.
As can be seen from the transmission sequence, when the relay base station radio apparatus 6 receives the call signal of the mobile station 8-β, the relay base station radio apparatus 6 locally returns a call response signal instead of the line controller 2 of the home zone system. As a result, the mobile station 8-β overflows the call response signal reception monitoring timer,
This prevents problems such as repeating the calling operation.

Further, as can be seen from the operation sequence of the satellite system at the time of receiving a call to the mobile station 8-γ located in the home zone of FIG. 12, the circuit switch 1 concentrates all incoming processing on a specific system. Instead of the method, a method of distributing incoming calls to a plurality of systems configuring the home zone is adopted. Further, in FIG.
An incoming call to γ is assigned by the circuit switch 1 to the communication channel (S-CH # q) of the system 1 (SYS-1). However, mobile station 8-γ is
Since it belongs to (SYS-2), it cannot be directly called as it is.

The common control unit 5-2 of the trunk line control device 5
Has data as to which system the mobile station 8-γ belongs to, and via the control channel (C-CH) of the system 2 in which the mobile station 8-γ is in a standby state, the system 1 (SYS) -1) communication channel (S-CH #)
q) is instructed by a channel designation incoming call signal. Upon receiving this command, the mobile device 8-γ receives the system 1 (SYS
The process moves to the communication channel (S-CH # q) of (-1), and enters a loop check signal reception waiting state.

As described above, the mobile station shifts the mobile station to the communication channel of the system that has received the incoming call by utilizing the characteristics that the mobile station can transmit and receive at all frequencies of the system, thereby enabling the circuit switch 1 to operate. In addition, complicated control such as restricting the incoming call processing to only selection of an idle communication channel and examining a received mobile station number to select a system to receive an incoming call is eliminated.

Further, according to the above-described method, regardless of the system to which the mobile station belongs, if there is only a free communication channel, the incoming call processing to the mobile station becomes possible. on the other hand,
Transmission from a mobile station located in the home zone is limited to the system to which the mobile station belongs, realizing traffic leveling. In FIG. 12, the relay line controller 5 instructs the relay wireless unit 4-1 of the satellite system to belong to the system 1 (SYS-1) in which the incoming call processing is executed in the home zone.

When the relay radio apparatus 4-1 receives the channel designation incoming signal to the mobile station 8-γ, it shifts to the communication channel (S-CH # q) of the system 1 and enters the satellite zone. It relays the loop check signal to the mobile station 8-γ. However, the mobile station 8-γ is located in the home zone and returns a loop check response.
The line controller then sends a call signal to the mobile station 8-γ.

Relay system control unit 5 for satellite system
Determines that the mobile station is located in the home zone because the paging signal has been transmitted in the home zone even though the loop check response signal has not been received from the satellite zone. The communication channel S-CH NO. Of the wireless device 4-1 and the relay base station wireless device corresponding to the wireless device 4-1 on a one-to-one basis. 1 is restored.

Note that the mobile station 9-ε located in the satellite zone receives a channel designation call signal, a loop check signal,
Even if the call signal comes, it ignores it. As described above, the following effects and advantages can be obtained by the satellite system relay system in the mobile communication system of the present invention. (1) One to one for the required number of communication channels in the satellite zone
Accordingly, the number of relay wireless devices is fixed, so that a relay system with a small device size can be constructed.

(2) Since the relay wireless device can be controlled so that it can belong to any system in the home zone, a reliable communication service can be provided in the satellite zone as compared with a system in which a fixed relay system is determined. Can be provided. (3) Since the relay wireless device is controlled so as to always belong to the system executing the incoming call processing, the incoming call processing for the mobile station located in the satellite zone is not available in the relay base station wireless device in the satellite zone. It is always executed as long as there is.

(4) Since the trunk line control device can perform outgoing call processing from mobile stations located in the satellite zone in a standby mode, connection quality is improved.
