FIG. 3 is a system configuration diagram showing a configuration example of a mobile communication system to which the packet base station device according to the first embodiment is applied, and FIG. 4 is a diagram showing a failure of the packet base station device according to the first embodiment. FIG. 5 is a sequence diagram showing a processing procedure in a case where the packet base station apparatus becomes a failure or switching of duplexing. FIG.
It is a flowchart which shows the procedure of the internal process when switching to T.

Next, the operation of the first embodiment when a failure occurs in the packet base station apparatus will be described with reference to FIGS.

In FIG. 3, the packet base station apparatus 2 of the first embodiment shown in FIG.
-1, 2-2 to 2-n, the packet base station devices 2-1, 2-2 to 2-n have the same configuration as the packet base station device 2, respectively, and are connected via the mobile communication line 4. The base station controller 11 is connected to the base station controller 1, and the base station controller 11 is connected to an exchange (not shown) via the exchange line 3.

In FIG. 4, the packet base station device 2-1
Is operating normally, the packet base station 2-1
The monitoring control unit 21 is connected to the base station control device 1 via the mobile communication line 4 by the host device I / F unit 114 and operated.

In this state, the main processing unit 113 of the monitoring control unit 21 in the ACT state stores the memory 11
The table of 32 stores start parameters at the time of ring establishment from the base station control device 1 and panel data in the packet base station device 2-1, and the I / O port 1133.
From the main processing unit 223, the own unit 21
The main processing unit sends out a signal A of "1" indicating that the signal is T, a signal B of "0" indicating that the other unit 22 is STBY, and a signal C of "0" indicating that there is no failure. 223
, The signal a corresponding to the signals A, B and C is received as "0", the signal b as "1", and the signal c as "0".

Next, when the CPU 1131 of the main processing unit 113 detects a failure (for example, clock stop, etc.) in the monitoring control unit 21 via the I / O port 1133,
The signal A is set to “0”, the signal B is set to “1”, and the signal C is set to “1” from the / O port 1133 to the main processing unit 223 and transmitted.

As a result, the monitoring control unit 22
As shown in (1), switching from STBY to ACT (S1),
Upon receiving the signal C “1” from the I / O port 1133 (S2), the main processing unit 223 sends a signal to all the units in the base station device 2-1 except for the monitoring control unit 21 in which the failure has occurred. From the bus access unit 221 to the common bus 11
A reset signal having a width of 0.2 seconds is transmitted via 0 to reset all units except the failure monitoring control unit 21 in the packet base station device 2-1.

Next, the CPU 22 of the monitoring control unit 22
31 restarts, but the link between the base station controller 1 and the packet base station 2-1 is disconnected, and the packet base station 2-1 may return a response to a signal from the base station controller 1. Since it is not possible (time over), the base station controller 1 detects that the packet base station 2-1 has gone down.

Next, the main processing unit 223 of the monitoring control unit 22 of the packet base station device 2-1 releases the reset,
A link connection request with the base station controller 1 is made via the higher-level device I / F unit 224, and the base station controller 1
, The link between the packet base station apparatus 2-1 and the base station control apparatus 1 is determined for the first time.

Next, when predetermined activation parameters are transmitted from the base station control device 1, the main processing unit 223 in the monitoring control unit 22 in the ACT state is
The boot parameters received via the host device I / F unit 224 are stored in the memory 2232, and the transmission / reception units 23 to 28 are set from the bus access unit 221 via the common bus 110 based on the received boot parameters. An ACK signal is returned for the station control signal 1.

As a result, when the monitoring control unit 22 receives the operation start permission signal from the base station control device 1,
A K signal is returned, and the operation of the packet base station device 2-1 is started under the control of the monitoring control unit 122.

It should be noted that the monitoring control unit 2
Since 1 is not reset and its state is saved, the cause of the failure can be investigated.

Next, when a package is exchanged or a new package is mounted in the monitoring control unit 21, the CPU 1131 of the main processing unit 113 sets the I / O port 1
133, these state changes are detected, and the fault A
The system switching process is performed assuming that it is not the LM.

That is, in this case, a signal A of “0”, a signal B of “1”, and a signal C of “0” are transmitted from the I / O port 1133 to the main processing unit 223.

On the monitoring control unit 22 side, the main processing unit 223 in the own unit transmits the signals a, b and c corresponding to the signals A, B and C from the main processing unit 113 to the I / O port 2233. (S in FIG. 5)
1) Since the signal C is “0”, the monitoring and control unit 21 detects that it is not a failure (ALM) (S in FIG. 5).
2), the main processing unit 223 sends a reset signal of 0.2 seconds to all units except the monitoring control unit 21 and its own monitoring control unit 22 on a signal path when a failure (ALM) is detected, Then, the other-system reset generation unit 227 sends the other-system reset detection unit 118
To the other system reset signal.

When the other-system reset detection unit 118 of the monitoring control unit 21 detects the other-system reset signal from the other-system reset generation unit 227, the other-system reset signal is generated for 10 seconds to reset the inside of the monitoring unit 21.

After sending the other system reset signal to the monitoring and control unit, the monitoring and control unit 22 resets its own unit 22 by the reset signal of 0.2 seconds from the reset detection unit 222 (FIG. 5). S
4).

The reason why the other system is reset for 10 seconds to the supervisory control unit 21 is that the supervisory control unit 21 is to be operated as an active system by a command from the base station controller 1. Is required to start before the monitoring control unit 21. In such a case, monitoring control or unit 2
2 is a position for resetting the monitoring control unit 21, and the order of resetting is determined by the monitoring control unit 2.
First, it becomes the monitoring control unit 22. On the other hand, the order in which the reset and release are started must be the monitoring control unit 22 and then the monitoring control unit 21.
In addition to the normal 0.2 second reset signal, another 10 second reset signal having a long reset time is used.

In this case, the sequence after the monitoring and control unit 22 issues a link connection request to the base station controller 1 after the reset is released is the failure (ALM) shown in FIG.
Since this is the case, the description is omitted.

FIG. 6 is a block diagram showing a packet base station apparatus according to the second embodiment of the present invention.

In FIG. 6, the packet base station apparatus 2a according to the second embodiment differs from the first embodiment shown in FIG. 1 in the following points.

That is, in the packet base station 2a according to the second embodiment, the monitoring control units 21a and 22a are different from the monitoring control units 21 and 22 in the packet base station device 2 according to the first embodiment. The transmission / reception units 23 and 28 have the same configuration as the packet base stations 2 and 2a in the first and second embodiments.

The supervisory control units 21a and 22a in the packet base station apparatus 2a according to the second embodiment
Unlike the monitoring and control units 21 and 22 in the case of the embodiment, the configuration does not include the other-system reset generation units 117 and 227 and the other-system reset detection units 118 and 228, and the bus access units 111 and 221 The device I / F units 114 and 224 have the same functions in both the first and second embodiments.

However, the reset detectors 112a and 112a included in the packet base station 2a of the second embodiment
2a is different from the reset detectors 112 and 222a,
It has a function of generating not only a normal reset signal of 0.2 seconds but also another system reset signal of 10 seconds.

The main processing units 113a and 223a included in the packet base station device 2a according to the second embodiment are different from the main processing units 113 and 223 according to the first embodiment shown in FIG.
However, in the case of the second embodiment, the memories 1132 and 2232 include the other-system reset generation units 117 and 227 and the other-system reset detection units 118 and 228.
And the reset detection units 112a and 222a
In order to generate the other system reset signal and perform the reset control,
The control program is stored differently from the case of the first embodiment.

Next, a mobile communication system to which the packet base station device 2a according to the second embodiment is applied is shown in FIG. 3, as in the case of the first embodiment. In this case, the packet base station devices 2a-1, 2a-2 to 2a-n are used instead of the packet base station devices 2-1, 2-2 to 2-n.
Think about it.

Next, an operation of switching from STBY to ACT due to a failure of the packet base station apparatus according to the second embodiment will be described.

The switching operation from STBY to ACT due to a failure or the like in the second embodiment can be performed by applying FIGS. 4 and 5 used in the description of the first embodiment. The main point that is possible and differs from the first embodiment is the method of the switching process by generating the other system reset signal. Therefore, only the point related to this point will be described below.

First, when the main processing unit 223a detects a failure (ALM) from the main processing unit 113a with the configuration shown in FIG. 2 (S1, S2 in FIG. 5), the bus access unit 2
21 via the common bus 110, the reset detection unit 3
1, a predetermined first command for generating a 0.2-second normal reset signal is output together with each unit address.

Finally, the first command is sent to the reset detecting section 222a of the own unit 22a to reset it. As a result, the monitor control unit 21a stores the ALM state, and the other units 22a, 23, and 28 are reset.

As in the case of the first embodiment, when the main processing unit 223a detects ACT from STBY other than the failure (ALM), the bus access unit 221 resets the ACT via the common bus. The detection unit 31 or 81 outputs a predetermined first command for generating a normal reset signal of 0.2 seconds together with each unit address, and then resets the other system for 10 seconds together with the address of the monitoring control unit 21a. A second command for generating a signal is output, and finally the reset detection unit 2 of the own unit 22a is output.
The first command is sent to 22a to reset it.

As described above, the operation after the reset signal is transmitted and the monitor control unit 22a issues a link connection request to the base station controller 1 after the reset is released is the same as that of the first embodiment. Is omitted.

As described above, the packet base station apparatuses 2 and 2a according to the first and second embodiments of the present invention are not limited to the conventional example even if they are duplexed with the monitoring control units 21, 22 and 21a, 22a. The common memory and local memory are not duplicated as in
3 and 113a and 223a store information such as the operation state only in the memory, and the monitoring control units 21 and 21a change from ACT to STBY due to a failure or the like.
2 and 22a switch from STBY to ACT, the main processing unit 22 on the monitor control unit 22 and 22a side
3, and 223a generate a reset signal of 0.2 seconds and a reset signal of 10 seconds to initialize the packet base station apparatuses 2 and 2a, and then newly transmit information such as an operation state from the base station control apparatus 1. Since the processing method is to acquire and store the data in the memory 2232, the configuration of the packet base station devices 2 and 2a can be simplified as compared with the related art, without requiring a common memory or a local memory as in the conventional example.

Further, since a common memory and a local memory are not required, the STBY derived from this can
Data transfer processing between memories and memory management at the time of switching from T and ACT to STBY becomes unnecessary, and the configuration of software as a whole can be simplified as compared with the related art.

[0062]

As described above, according to the present invention, the duplicated first and second supervisory control units, a plurality of transmitting / receiving units, and the communication between the first and second supervisory control units and the plurality of transmitting / receiving units are provided. And a common bus for connection.
And each of the second monitoring and control unit, if one is an active system, the other is used as a standby system, and a higher-level device interface means for connecting to a higher-level device; a bus interface means for connecting to a common bus; It controls the inside of its own unit and processes transmission / reception signals via the higher-level device interface means, and monitors the status of units other than its own unit via the bus interface means when it is operating. One of the supervisory control units in the active system state receives a request for system switching from the active system to the standby system due to some failure or due to some state change other than the failure including package replacement in the one supervisory control unit. System switching detection means that is detected by the other monitoring control unit, and a system switching request is issued by the system switching detection means. A first reset signal generation requesting unit for requesting all units except the one monitoring control unit to generate a first reset signal via a common bus, and a first reset signal generation requesting unit from another unit via the common bus. When a reset signal generation request is detected, a first reset signal generation means for generating a first reset signal and initializing the inside of the own unit and a system switching request based on only the state change of the system switching detection means are detected. In this case, the second reset signal generation request means for sending a second reset signal generation request signal to one monitor control unit and the second reset signal generation request means from the other monitor control unit. And a second reset signal generating means for generating a second reset signal upon receipt of a request for generating the second reset signal and initializing the internal unit. Thus, even if the monitoring and control unit is duplicated, the configuration does not require a common memory as in the conventional example, and the entire device can be simplified. There is.

Further, by adopting a configuration without a common memory, there is an effect that a control program of the entire apparatus at the time of switching the duplexing can be simplified.
