Abstract

PURPOSE:To store position information of a mobile station in service in an adjacent zone by a radio relay station of a home zone by providing a position information broadcast means making broadcast via an outgoing control channel to a radio relay station of the adjacent zone. CONSTITUTION:When a mobile station MS of a subscriber station number 52 moves to an adjacent zone Z1, out of synchronism is caused. The mobile station MS sets the channel to an outgoing control channel of system code 14, the synchronization is obtained and an incoming control signal F' is sent automatically from the incoming control channel at the same time. A relay station of the adjacent zone receives the said position data received through the incoming control channel via the outgoing control channel by using a position information program. A relay station BSH of a home zone ZH awaits the outgoing control signal F received by a broad band reception antenna 1H by using a broad band reception program and fetches the signal by a broad band command program.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a location registration method, and more particularly to a location registration method in which location information of a mobile station that has moved within an adjacent zone is registered at a wireless relay station in a home zone. .

[Technical background of the invention and its problems]

In a system in which the service area is divided into a home zone and a plurality of adjacent zones, as shown in Figure 1, the home zone zH has a wireless relay station BSH, and the adjacent wireless zone zn (n is 1
~6), wireless relay stations BSn (n is 1 to 6) are installed. The wireless relay station BSH in the home zone and the wireless relay station BSn in the adjacent zone (the subscript H2n indicates the home zone and the adjacent zone, respectively) have wide-area receiving antennas IH and 1.
1 (n is 1 to 6) transmitting antenna 2. ．． 2n (n is 1 to 6
), receiving antennas 3H, 3H (n is 1 to 6), and provides a relay connection service to a unit subscriber station group consisting of a command station FS and a mobile station MS. Relay connection services include home zone service and adjacent zone service. Home zone service is a call within the wireless zone to which the subscriber station belongs. The joining station group is 1 supervisor code A shown in Figure 6.
. It has a unique group code consisting of system code B0 (4 bits) and knee decode C3 (10 bits). For example, the MCA system is 800 M
The Hz band is divided into 25 blocks, and each unit block consists of one control channel line and 15 communication channels (the final block is 14 lines). The wireless relay station BS has one or more system codes Bm (m is 0 to 63), and the unit blocks are allocated in correspondence to each system code Bm. Adjacent zones have 1 supervisory code AO.
System code B regardless of (Telecommunications Supervision Bureau number)
It is configured so that it can be identified by m.

In the following description, Bo e Bn (n is 1 to 6) refers to wireless relay stations BSH9BS1 and BSH9BS1 with multiple system codes Bm.
...BS, (7) Wireless zone Z, which is the home zone
Assume that system code Bm indicates a system code Bm to which a specific unit subscribing station group of H can subscribe and can receive a connection service in each wireless zone zn.

In addition, the radio zones of the radio relay stations BS, , BSn have a radius of 14 to 15 km, and the radio relay stations BSH, BSn transmit the radio waves of the assigned channels to the wide-area receiving antenna "H*
1n (n is 1 to 6) so that they can receive each other. The communication channels allowed per unit block are 4 to 15 channels, and the number of subscriber stations accommodated is 1000 to 5000. It operates with 0.5 calls per hour, average holding time of 20 seconds, and 14 erlangs of waiting calls per 15 channels.

The wireless relay stations BS, BS, BSn, which are upper-level stations, transmit the downlink control signal F shown in FIG. 2 as a frame signal to the subscribing stations, which are lower-level stations. The downlink control signal F is bit synchronized 5l (
16 bits), frame synchronization 82 (15 bits), 1st
Block data BL1. It is composed of second block data BL2. Both the first block data BL and the second block data BL2 ((72-bit configuration (valid data is 30
The remaining bits are parity pits and are B, H, and C codes. ), and the first block data BL1 has the first supervisor code Ax (4 bits) system code "x" as shown in FIG.

0 to 49 bits) and channel number d4 (50 to 59 bits)
Consists of bits). As shown in FIG. 5, the upstream control signal F' is composed of bit synchronization sl, frame synchronization S2, and block data BL. Block data BL, as shown in FIG. 6, is command d5. Reserve d6. Destination system Bm (m is 0 to 63) Individual subscriber station number D0 Supervision code A. , system code Bo.

Consists of user code C8. The subscriber station always receives the downlink control signal F and performs bit synchronization s1 and frame synchronization 32.
and the first block data BL shown in FIG.
1 supervisor code Ax (for example, when the home zone is A, x = 0), system code Bx (x in the home zone)
=0. In the adjacent zone, x=n) is tested. The data necessary for the test is written in the ROM. If you pass the test, you will be able to make and receive 9 calls.

The system code is B when the mobile station MS is active in the wireless zone ZH to which it belongs. The downlink control signal F is received on the downlink control channel related to the system code Ao and the system code B0. If the mobile station MS moves to the adjacent zone zn in this state, synchronization will be lost due to inability to perform verification.

To resolve the synchronization loss, first display the synchronization loss. After recognizing the synchronization loss, one of the system codes Bn is written in the ROM and taken out. A downlink control channel related to system code Bn is set. If the synchronization is not resolved, steps such as retrieving another system code Bn are taken. When the synchronization is resolved and the mobile station MS makes a call, the mobile station MS and the command station FS receive the designation of the communication channel to be used via the downlink control signal. The mobile station MS can report position information to the command station FS through a designated communication channel. The command station FS files this position information. The command station FS and other subscriber stations can use this location information to place calls to the radio zone in which the mobile station MS is active.

However, the transmission of position information from the mobile station MS to the command station FS has the disadvantage that it must go through a communication channel regardless of voice or code.

An uplink control signal F' is sent from a subscriber station that is synchronized with the downlink control signal F.
It takes 5 to 6 time slots during off-peak hours for a call sent via the wireless relay station BS to be accepted by the wireless relay station BS. Furthermore, operation sequences such as the condition that the subscriber station group is not in use of the communication channel and the reservation when all communication channels are busy become factors that increase the traffic on the control channel. For this reason, there are drawbacks such as having an adverse effect on normal telephone calls not only during busy times but also during off-peak times. Furthermore, it would be better to have a method in which the command station can obtain multiple position information upon request only when the position information is needed, so it is problematic to notify the command station every time position information is generated.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a location registration method that allows a wireless relay station in a home zone to store location information of a mobile station active in an adjacent zone.

[Summary of the invention]

In the present invention, the wireless relay station captures the location information transmitted from the mobile station to the wireless relay station via an uplink control signal when the mobile station moves to the home zone and the adjacent zone and establishes frame synchronization, and the captured location information is transmitted to the wireless relay station. It is designed to be organized into control signals. A command indicating that position information is being transmitted is added to the downlink control signal containing the position information. A wide area receiving device provided in a wireless relay station in the home zone receives a downlink control signal transmitted from a wireless relay station in an adjacent zone. The location information of the mobile station included in the received downlink control signal is registered in the location information storage means provided in the radio relay station in the home zone for each subscriber station group and for each individual subscriber station.

[Embodiments of the invention]

An embodiment of the location registration method according to the present invention will be described in detail with reference to the drawings.

In FIG. 7, 6 is a command analysis program.

The command analysis program 6 is a subscriber station location information compiling means that compiles the subscriber station location information compiled into an uplink control signal into a downlink control signal. The command analysis program 6 uses the uplink control signal FH' received via the receiving antennas 3H and 3n shown in FIG.

The main flow of the standby program 4, which is waiting for a call by Fn', is branched via the connector z8 to the connector 22.
2. to return via. In process 7, the upstream control signal F'
The command d5 of the fetched block data BL3 is analyzed. When the value of command d5 is "01", it is a general connection,
When rlOJ, wide area connection is determined, and when "11", position data 9 is determined. Each program indicator PI
is set in process 8, and the branch destination is determined based on the value of the program indicator PI. When PI=3, position data is transmitted from the mobile station MS rather than a normal call, so in step 10, the subscriber station number of the e-mobile station MS is entered in the request transaction RQTR. FIG. 12 shows the data purchase of request transection RQTR. AOz
The group code used by BOt co for normal calls, D
o is the subscriber station number.

Do has a 6-bit configuration and can represent 0 to 63. 0-63
In the above case, an unimplemented user code COs, for example, the oldest number 1023 is assigned. In process 11, the request transaction RQTR is registered in the waiting queue Q1, and the process returns to the main program.

FIG. 8 is a flowchart of the wide area command program 13. The wide-area command program 13 is a position information acquisition means for acquiring the position information of the subscriber station from the downlink control signal in which the position information of the subscriber station received by the wide-area receiver. Wide area command program 13 is wide area receiving program 1
2, is executed via connector z4, and returns to wide area reception program 12 via connector z5.

The wide area reception program 12 is a program that is executed when the wide area reception antenna IH, 11 (n is 1 to 6) shown in FIG. 1 waits for a downlink control signal Fn. In process 14, the wide area command program 13 receives a downlink control signal F transmitted from the wireless relay station BSn in the adjacent zone via the downlink control channel.
Take it. The command d2 of the first block data BL1 shown in FIG. 3 of the received downlink control signal F is judged in the judgment box 15. Command d2 is "0" for notification, "1" for reservation, "2" for listening, "3" for free, and "4" for command d2.
Since "5" is the channel designation, "5" is the -simultaneous command, and "6" is the lower 9 control channel switching, "3" is the wide area position designation. Therefore, if the value in the decision box 15 is not "3", the process returns to the wide area reception program 12 via the decision box 15.

When it is "3", process 16 is executed. Since one of the plurality of system codes of the transmission source of the downlink control signal F is written in the BX area of the first block data BL□, this system code is converted into an identification number assigned to the adjacent zone. Identification number 0 is the home zone, and numbers 1 to 6 are adjacent zones. In process 16, the converted identification number is written into the line memory LM (26 to 28 bits) of the edit transaction EDTR shown in FIG. Processing 17
, 18, the user code C of the second block data BL2

The data of the request transaction RQTR, in which the location information is organized by the location information organizing means, is the time-activated program shown in FIG.
Device information program 2 consisting of downlink control signals with 0
0 indicates whether there is a waiting call or not and the waiting queue Q in the judgment boxes 21 and 22.

It determines whether there is an RQTR registered in , and transfers control to the execution management program according to the determination. In process 23, the request transection RQTR is taken out from the waiting queue Q1. For the command d2 of the first block data BL1 of the downlink control signal F, "3" is determined as a position information transmission command, and the command is organized in process 24. Request Trump comb in process 25.

Since the organization has been completed, position information is transmitted in step 27. After executing process 27, control is passed to the execution management program.

A group editing program 28 shown in FIG. 10 is provided as a subscriber station group location information storage means for editing and storing acquired subscriber station position information for each subscriber station group. The group editing program 28 is a time-activated program with an activation cycle of 21 seconds (1
44 frames). Group editing program 28
When activated, it is determined in a decision box 29 whether or not the edit transaction EDTR is registered in the waiting queue Q2. If the edit transaction EDTR is registered in the waiting queue Q2, the edit transaction EDTR is hunted in process 3o. Translator TL
R consists of 0 to 1023 words, electrical model code AO, and system code B. The data shown in FIGS. 14 and 15 are written in the group code consisting of the knee decode C0 and the knee decode C0, depending on whether the subscriber station group is installed or not. Pits 0 to 7 are transaction index SIN, pits 8 to 10 are sub index +S, and pits 27 to 28 are transaction class SCL.

The 31st bit is set to flag FLG (1 if implemented, 0 if not implemented). In other areas, write the number of lines, user code C6, etc. as empty or occasional blocks. In process 31, as shown in FIG. 11, the translator TLR is indexed by knee decoding C8. The indexed contents are stored in the calculation register R1.

In process 32, the translator address TRA is modified with the value of the transaction class SCL stored in the calculation register R1 to obtain the transaction address ΔWTR. When the transaction class SCL is 0, the start address of Sunward transaction 3WTR1 is written. 3WTR is used by being divided into memory blocks of 0 to 2, 3 to 5, 6 to 8, and so on.

Each unit memory block corresponds to subscriber station numbers 0 to 31. 6W when transaction class SCL is 1
TR is divided into 6 food memory blocks and has 64 subscribed stations.
When SCL is 2, 24 WTR is used for 24 word memory blocks and 256 stations are added. When SCL is 4, 42 WTR is used for 4 stations.
512 stations have joined the 2-word memory block, and when the SCL is 5, there are 96 WTRs and 1024 stations have joined the 96-word memory block. Furthermore, the memory block size SIZ
is written in the memory area at the same location of the transaction address TRA along with the transaction address ΔWTR.

The starting address of the transaction is determined in process 32.

The size SIZ of the unit memory block is accumulated in the calculation register R3 in step 33, and the address obtained by modifying the start address of the transaction with the numerical value of the calculation register R8 becomes the start address of the memory block allocated to the joining station group. The starting address of this memory block is obtained in step 35. Once the starting address of the memory block allocated to the joining station group is determined, this memory block is assigned to the joining station number of the edit transaction EDTR. It must be divided into subblocks equivalent to 64 circuits, which can be expressed as .

The address of the desired memory area is determined by dividing the data into 6 words. Division into sub-blocks is performed in process 34 and process 36 using sub-block +S. Participating station number. Is it necessary to judge whether it is in the younger numbers 0-31 or the older numbers 32-63? , class 8 is used. Participating station number. If it is between 32 and 63, the subscriber station number is determined in step 39. 31 is subtracted from and stored in the calculation register R1. Next, in process 40, 3 is added to the arithmetic register R2 in which the address of the determined sub-block is stored, and the number of the subscriber station with the oldest number is calculated. Get the memory location corresponding to . Judgment indexes 41, 44, and 47 judge whether each of bits 0 to 2 of the line memory LM of the edit transaction EDTR is 1 or 0. Process according to judgment 4
2, 43.

44. Rewrite the corresponding memory to O''! or 1 at 45, 46, and 47.

A flag FLG is set at pit 31 of the edit transaction EDTR, and when the flag FLG is 0, a write is 1, and a read is made.

Here, in a subscriber station group with 60 subscriber stations, knee decode C
8 is 6, the system code Bo of the home zone is 9, the system code Bm of the adjacent zone is 14, and the subscriber station number that moved to the adjacent zone is 52.

When the mobile station MS with subscriber station number 52 moves to the adjacent zone z1, synchronization will be lost. When the mobile station MS tunes to the lower control channel with the system code 14, synchronization is achieved and at the same time it automatically transmits the upper control signal F' from the uplink control channel. At this time, the numerical value of command d5 shown in FIG. 6 is "3".
", Bm is 9, Do is 52, Bo is 9, and co is 6. The relay station in the adjacent zone uses the position information program 20 to transmit the position data received on the upper control channel via the lower control channel. The lower control signal F is shown in Figure 3.
Bx shown in FIG. 4 is 14, d2 is 3, Bm is 9, Do is 52, and co is 6. Home zone zH relay station BS
In H, the lower control signal F received by the area receiving antenna IH
is waited for by the wide area reception program 12 shown in FIG. 8, and taken in by the wide area command program 13. In the group editing program 28 shown in FIG. 10, the translator TLR is searched by 6 of the knee decode co. Translator T L R
, the flag FLG is 1 and the transaction class ScL
is 1 (the number of subscribed stations is between O and 63), the subindex +S is O, and the runtime index SIN is, for example, 7. transaction address TR
By adding 1 to A, the address of the transaction address ΔWTR in which the first address of 6WTH is written is obtained. If the starting address of 5WTR is determined, for example, address 1000, the transaction index SIN is 7.
Address 42 multiplied by 6 of Z is 10 of the first address of 6WTH
00 address to obtain the address of the memory block allocated to the subscriber station group. Furthermore, since the subscriber station number is 52, which is an old number, 3 addresses are added to address 1042, and address 1045 becomes the desired address. The 21st bit (=52-31) of addresses 1045, 1,046, and 1047 becomes the memory area assigned to subscriber station number 52. If the adjacent area is 1, then 1
The 21st bit of address 045 is 1.1046, 104
Set the 21st bit of address 7 to 0. Further, when the number of subscriber stations increases to 82, the dummy user code C6, for example, the oldest number 1023, is used to correspond to the added subscriber station number. The transactions used are 12WTR,
)Transaction index SIN of Lancer TLR6 and TLR1o23 is the same value, one subindex +S is "0" and shares 0 to 63, and the other is "1"
64 to 127 will be shared. Knee decode C8 is 102
3 is not implemented, so flag FLG is set to O. Knee decode C8, which is not implemented, does not require normal general and wide area connections, so it does not affect the verification of two outgoing and incoming calls.

The number of request transactions RQTR and edit transactions EDTRO is determined depending on the traffic.

Generally, the proportion of the total number of subscribed stations belonging to a group of subscribed stations with 30 or less subscribed stations is 40 to 60%, and in the case of 60 or less, 90%
It is about 100%. Therefore, large-capacity memory transactions can be allocated or expanded according to demand.

The command station FS requests the registered position information from the wireless relay station BS via a command, and sends the registered position information to the wireless relay station B via the communication channel.
Sent from SH. The command station FS can know the received position information on a CRT or hard copy.

〔Effect of the invention〕

In the location registration method according to the present invention, when a wireless relay station in an adjacent zone receives location information of a wireless mobile station that has moved into an adjacent zone from the mobile station via an uplink control channel, the location information is organized into a downlink control signal and is used for downlink control. A wireless relay station in an adjacent zone is provided with a position information broadcasting means for broadcasting via a channel, and when a wide area receiving device provided in a wireless relay station in a home zone receives the above position information via a downlink control channel, the position of the mobile station is determined. Since the wireless relay station in the home zone is provided with a position information storage means for editing and storing information for each mobile station group, the system is characterized in that position information is exchanged through a control channel.

Therefore, the location information can be registered regardless of the operation sequence of the general connection, and the processing of the location information does not have an adverse effect on the general connection. Furthermore, since the location information is edited for each subscriber station group or individual subscriber station and registered in the radio relay station of the home zone, the editing function for each individual subscriber station on the command station side can be omitted.
