JPH0267026A - System for limiting speech time of mobile body telephone system - Google Patents

Abstract

PURPOSE:To prevent imprudent long time telephone from being placed by providing a reporting means to report speech time by anticipation at the time of issuing a call at a mobile terminal, detecting the information of reported speech time by a mobile body telephone exchange and processing it as charge information, and disconnecting the call compulsorily when the reported speech time elapses. CONSTITUTION:The mobile body telephone exchange 3 is equipped with a central processing unit(CPU) 36, a subscriber data memory(SDM) 37 in which subscriber data is stored, and a charging data memory 38 to store charging data at every subscriber. The subscriber of the mobile terminal 1 anticipates time length required for a speech in advance at the time of issuing the call, and sends it to the mobile body telephone exchange 3 via a radio base station device 2. While performing the speech, the CPU 36 monitors the speech by reading out speech time data written on the SDM 37, and disconnects the speech compulsorily when the reported speech time elapses. In such a way, limitation for the speech time can be applied corresponding to the status or will of the subscriber at the time of issuing the call.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a call time limit system for a mobile telephone system.

[Conventional technology]

Conventionally, in order to limit call time in this type of mobile telephone system, the mobile telephone exchange accommodating a group of mobile terminals has a function that forcibly disconnects the call after a predetermined period of time has elapsed.

[Problem to be solved by the invention]

In the call time limit method of the conventional mobile telephone system described above, the upper limit of the callable time is predetermined semi-fixably and uniformly for all subscribers by the exchange.
The drawback is that call time is limited regardless of the subscriber's circumstances or intentions when making a call.

[Means to solve the problem]

The call time restriction method for a mobile telephone system of the present invention is a mobile telephone system comprising a mobile telephone exchange and a mobile terminal, wherein the mobile terminal is provided with a reporting means for predicting and reporting the call time at the time of making a call, The mobile telephone exchange is characterized by comprising a processing means for detecting the declared call time information and processing it as billing information, and a disconnection means for forcibly disconnecting the call when the declared call time has elapsed. do.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a system block diagram showing one embodiment of the present invention.

In FIG. 1, a mobile terminal l is connected to a mobile telephone exchange 3 via a radio base station device 2, and is further connected to a general telephone network (
It is configured to communicate with a called subscriber 5 via a NW (hereinafter referred to as NW) 4. Mobile telephone exchange 3 is wireless base station equipment 2
．． Incoming trunk (hereinafter referred to as ICT) 31 and outgoing trunk (hereinafter referred to as ○GT) 33 that interface with NW4, respectively, and communication path switch (hereinafter referred to as SW>32) and I through 5W32.
A special sound trunk (hereinafter referred to as 5PT) 34 that sends a special notification sound to the CT31 side and ICT3111! via the 5W32!
A register that receives dial information from I (hereinafter referred to as REG)
) 35, a central processing unit (hereinafter referred to as CPU) 36 that controls sequence control within the mobile telephone exchange 3, a subscription data memory (hereinafter referred to as SDM) 37 that stores subscriber data, and stores billing data for each subscriber. A charging data memory (hereinafter referred to as CHM) 38 is provided.

Next, the operation of this embodiment will be explained.

When making a call, the subscriber of the mobile terminal 1 estimates the length of time required for the call in advance according to the call charge, and then sends a special number from the mobile terminal 1 according to the length of time (for example, a special number for declaring the call time "#").
Following ``'', ``180'' (without indicating the call time) is sent to the mobile telephone exchange 3 via the radio base station device 2. In the mobile telephone exchange 3, RE is sent via ICT31 and 5W32.
G35 receives this special number and transmits it to CPU36.

The CPU 36 determines that this is a time limit request from a subscriber of the mobile end woodworking company, writes '180'' seconds to this subscriber's address in the SDM 37, and controls the 5W32 to
A special sound is sent from the PT 34 to notify the mobile end woodworking subscriber that the declaration has been accepted. The subscriber of the mobile terminal 1 then dials the telephone number of the called subscriber, and the mobile telephone exchange 3 uses the ICT
31 5W32.0GT33. Connection processing is performed to the called subscriber 5 via the NW 4, and the subscriber of the mobile terminal 1 and the called subscriber 5 enter into a conversation.

During this call, the CPU 36 reads the call time data written in the SDM 37 and monitors the call on the ICT 31.
Before the pre-declared time (here 180 seconds) has elapsed (
For example, a generally known forecast sound is sent to the mobile terminal 15 seconds in advance), and when 180 seconds have elapsed, the 5W32 is controlled to forcibly disconnect this communication path. After that, CPU36 is SDM3
The time limit data (180 seconds) written in C8M38 is transferred to and stored in C8M38 along with other billing data as billing information.

The time limit data in the C8M38 is used to calculate the call charge for the call at a lower rate than in the case where the call time is not declared and give preferential treatment when processing billing data.

In addition, the time limit data written in SDM37 is C8.
After being transferred to M38, the call is automatically deleted and prepared for the next call. However, if the call time is not declared in advance, the call time is not restricted by forced disconnection, and the general call fee structure is applied. No preferential treatment will be given.

〔Effect of the invention〕

As explained above, according to the present invention, the subscriber of the mobile terminal declares the expected call time in advance according to his or her will, and the call time is set commensurate with the call charge. This has the effect of eliminating the need for hourly telephone calls and making use of the particularly limited number of wireless lines in the mobile telephone system.
