The gist of the present invention resides in a transmission restriction system in a mobile communication system for restricting transmission in wireless communication performed between mobile stations via a base station, wherein the transmission restriction data is provided on the mobile station side. The mobile station is provided with a transmission restriction system in which the transmission restriction is performed based on the transmission restriction data stored in the storage means.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration of a wireless access (Wireless Local Loop: WLL) system according to an embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a WSC (Wireless
Service Switch) and LS (Local Switchin)
g) Connected to station 6. 2 is MAT (Maintenance a
nd Administration Terminal), 3 is CS (Cell Stati)
on), 4 is SSU (Single Subscriber Unit), 5 is T
EL (Telephone).

[0009] MAT2 is a maintenance terminal connected to WSC1. MSU2 has the SSU used in this embodiment.
4 is stored. WSC1 executes a procedure for downloading transmission restriction data to SSU4 in accordance with an instruction from MAT2. SSU
4 executes a procedure for downloading and a procedure for restricting transmission. The SSU 4 has a ROM for storing transmission restriction data downloaded from the MAT 2.

Next, the operation of the radio access system according to the present embodiment having the above configuration will be described with reference to the sequence shown in FIG.

FIG. 2 shows a download sequence of the transmission restriction data. (1) The MAT 2 instructs the WSC 1 to transmit a download start request to the SSU 4. At this time
The transmission restriction data (A) is transferred from the AT2 to the WSC1.

(2) WSC1 is the SSC specified by MAT2.
Make a call to SU4. (3) The CS 3 performs a normal incoming call process on the SSU 4. (4) When the SSU 4 responds, the WSC 1 instructs the CS 3 to perform a call setting designating a non-ringing incoming call. After this, CS3
The call setting for non-ringing designation is performed for SSU4. (5) When the terminal authentication is performed between CS3 and SSU4 and the incoming call to the terminal is permitted, CS3 accepts the call setting by WSC1.
Send to (6) WSC1 instructs CS3 to call SSU4. (7) The SSU 4 responds by automatically off-hook without sounding.

(8) After confirming the response, the WSC 1 transmits a download start request to the SSU 4 by the extended supplementary service transfer. (9) The SSU 4 transmits a report of the download start request to the WSC 1 by the extended supplementary service transfer. (10) The WSC 1 transmits the transmission restriction data (A) to the SSU 4 by the extended supplementary service transfer.

(11) The SSU 4 writes the transmitted outgoing call restriction data (A) in the ROM inside the SSU 4. Thereafter, the SSU 4 transmits to the WSC 1 that the transmission of the transmission restriction data (A) has succeeded by the extended supplementary service transfer. (12) When the download is completed, the WSC1 sends a download end request to the SSU4 by the extended supplementary service transfer.
Send to (13) The SSU 4 transmits to the WSC 1 that the download end request has been confirmed by the extended supplementary service transfer. WSC1 executes call disconnection and ends the download procedure. (14) When the call disconnection is completed, the SSU 4 restricts the transmission from the SSU 4 based on the written transmission restriction data.

The release of the transmission restriction is realized by invalidating the transmission restriction data written in the SSU by releasing the transmission restriction from the MAT. Transmission restriction release is also realized by executing a download procedure and downloading restriction release data to the SSU.

In the present embodiment, the use of the non-ringing incoming call procedure for the download procedure, the use of the extended supplementary service transfer, and the addition of the transmission restriction data to the data to be downloaded make it possible to reduce the SSU data change and the transmission restriction. It is characterized in that it is possible in a single procedure.

The radio access system according to the embodiment is configured as described above, and has the following effects.

First, effective use of radio frequency is mentioned. That is, after the SSU 4 accesses the wireless line, the terminal LS station 6 can perform the process of identifying the outgoing call restriction in the upper LS station 6. Since it is not necessary to access the radio line and transmit the invalid call to the upper LS station 6, the radio frequency can be effectively used.

Second, it is necessary to secure subscriber data quality by realizing data download. That is,
The data was rewritten to the ROM of SSU4 via the PC, but the data can be downloaded from MAT2 and WSC
1 and SSU4 data can always be synchronized and subscriber data quality can be ensured.

Third, there is a reduction in the number of SSU maintenance steps. That is, when the SSU4 needs to be replaced due to a failure or the like, there is no need to rewrite the SSU4 subscriber data on site, and only the SSU4 is replaced, and the data becomes M
Since the data can be rewritten by downloading from the AT2, the number of maintenance steps can be reduced.

In the present embodiment, the present invention is not limited to the above-mentioned radio access system, but can be applied to a mobile communication system suitable for applying the present invention. Hereinafter, other embodiments of the present invention will be listed.

(1) WSC1 controls transmission from CS3 and regulates all SSUs under CS3. Transmission restriction control is performed not on SSU but on CS and all SSUs under CS are regulated. (2) Data can be downloaded from MAT2 to CS3 Subscriber data can be downloaded from MAT2 to CS3. (3) Writing outgoing call restriction data directly to the ROM of SSU4 and restricting outgoing call An external PC is connected to the SSU, and the outgoing call restriction data is included in the subscriber data to restrict outgoing call of the corresponding subscriber. Can be.

Further, the number, position, shape, etc. of the above-mentioned constituent members are not limited to the above-mentioned embodiment, but can be set to a suitable number, position, shape, etc. for carrying out the present invention.
