Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a billing control system that makes it possible to arbitrarily vary billing to mobile subscribers in mobile communications.

In conventional mobile communications, a slave station format has been adopted in which outgoing trunks and incoming trunks are used as relays between mobile exchanges and accommodating exchanges.

For this reason, billing for mobile subscribers has been accomplished by installing billing devices such as a billing link and a controller in the mobile exchange that connects the mobile subscriber frequency meter and the trunk, but the billing control device is expensive and economical. Not only is it disadvantageous,
The installation location of mobile subscriber frequency meters was different from that of general subscribers, and there were drawbacks such as in-station construction and maintenance becoming difficult. This invention improves the slave station format in which outgoing trunks and incoming trunks are used to relay between a mobile exchange and a accommodating exchange, and provides control for controlling call lines and frequency meters from the accommodating exchange (local exchange) to correspond to mobile subscribers. A line is drawn in and a circuit for mobile subscribers is installed to accommodate mobile subscribers, so that charges can be made to the frequency meter installed in the same location as general wireline subscribers using the total pulses from the local exchange. , so that there is no need to install a new billing device,
Furthermore, when configuring a tenant, the present invention attempts to provide a billing control method that identifies the tenant number of the calling/receiving subscriber and allows selection of billing.

In this case, there is no charge for the same tenant, and if the called party is a mobile subscriber, the called party can also be charged. Next, the present invention will be specifically explained based on illustrated embodiments.

FIG. 1 shows an example of the relay system according to the present invention, in which a mobile subscriber MSUB (7) Ao is connected to the same mobile subscriber M
The case where a call is made to Haruka 1 on SUB (■) will be explained.
When A0 of the mobile subscriber MSUB makes a call, the mobile-to-mobile bidirectional trunk MBWT (RI 0) detects the call, captures the mobile-to-mobile register center MRS, and stops the idle signal.The mobile-to-mobile register center MRS When activated, it sends a number registration request signal to Ao of the mobile subscriber MSUB and receives and stores the number registration signal from the mobile subscriber MSUB.Subsequently, in order to receive dial pulses, the mobile A dial tone is sent to the mobile subscriber MSUB, and when all digits are received, the marker MKR as a line control device is started.The marker MKR is information from the mobile register center MRS and is sent to the black 0 of the mobile subscriber MSUB. Corresponding mobile subscriber circuit MLC (7) black 0 and trunk MBW
Tf) Connect with black 0. At the same time, the caller's calling number and the subscriber number of the called party are checked, and if they are the same tenant, non-charging information is written to the mobile subscriber circuit MLCO0. When the mobile subscriber circuit MLC is activated, the local exchange E. Activate E.O in the same way as when calling from a regular telephone, send the called number stored in the MRS, and call the local exchange E.O. O connects calling and receiving subscribers via an intra-office trunk 10T.

Mobile subscriber MSUBf) 1 uses local exchange E. When a ground signal is received from O to a control line provided corresponding to the mobile subscriber circuit MLC, a call receiving operation is started and marker MKR is activated. Marker MKR extracts the called mobile number from the activated mobile subscriber MLC number, selects an empty trunk (MBWT black 1 in this case), and selects an empty trunk (MBWT black 1 in this case). and trunk MBW
At the same time as connecting with black 1 of T, the mobile center MOS
The called mobile device number is captured and sent to the center MOS. The center MOS sends the called mobile number via &1 of the trunk MBWT, calls black 1 of the mobile subscriber MSUB, and when a response signal is returned from the mobile subscriber MSUB, the center MOS sends the called mobile number via &1 of the trunk MBWT. (f) At the same time as sending a paging completion signal to black 1, a bevel ringing signal for mobile subscriber MSUB 1 is sent to ring the called subscriber.
When the called party answers, the response signal from the trunk MBWT is disconnected, and the trunk MBWT f) detects the called party's response and returns the response signal to the calling party, so that the communication between the calling party and the called party is interrupted. You can make calls. Regarding billing, if it is the same tenant, there is no charge to the calling party, but if it is not the same tenant, billing is done by registration pulse from the trunk IOT in the own station, and the called party is also charged by the trunk MBWTf)
Black 1 of the mobile subscriber MLC receives the registration pulse from Yahoo!
to relay the information and charge for it.

FIG. 2 is a diagram for explaining billing control. As explained in FIG. 1, when the mobile subscriber MSUB makes a call, the marker MKR drives the switch Sw, and the mobile subscriber MLC and the trunk MBWT.

In this case, relays B, OG, and S are operating in the trunk MBWT, and the communication line is connected to the mobile register center M at the contact S.
RS, and from the above center MRS to local exchange E.
．． After sending the called party number to O, the relay S is restored, so the contact S is also returned and the ringing tone is returned to the calling party.
In the mobile subscriber circuit MLC, the relay CO is activated when it is connected to the trunk MBWT. Local exchange E.
When O is activated, earth air is supplied to the CO lead, but relay ST does not operate because it is disconnected at contact CO. When the called party answers, local exchange E. O to CO
A registration pulse is supplied to the reed, and the frequency meter M
The degree of ET increases. If the calling/receiving subscriber is the same tenant, the marker MKR is used for verification, and the relay CH is activated to transmit the call to the mobile subscriber circuit ML through the trunk number expansion tree-TN.
Since relay NM of C operates and holds, local exchange E
．． Even if a registration pulse is received from O, the frequency of the frequency meter MET does not advance. When mobile subscriber MSUB terminates the call, trunk MBWT is transferred to local exchange E. A line communication signal (loop break between line A and B) is sent to O, and the switch SW is also restored for recovery, and at the same time, the relays CO and NM of the mobile subscriber circuit MLC are restored. Termination charge is performed by relaying the registration pulse from the trunk MBWT through the mobile subscriber circuit MLC.

When the trunk MBWT is operating on an incoming connection and the called party answers, the relay MP of the trunk MBWT will be approximately 1
It operates for about 00ms. +50V battery connects resistance R to contact M
The circuit from p to contact b to terminal C to switch to terminal C1 of MLC to diode D is supplied for about 100 ms, so the relay MP of the mobile subscriber circuit MLC is operated during that time.
Since the +50V battery of the mobile subscriber circuit MLC is supplied by the circuit from resistor R to contact Mp to contact Nm to terminal MET,
The frequency of the frequency meter MET advances. The operation of the relay MP is not limited to one time, and can be registered multiple times depending on the call duration. As explained above, the present invention provides a mobile subscriber circuit for a mobile subscriber, into which a telephone line and a control line are drawn from the subscriber terminal of a local exchange;
By configuring the system to be equipped with a line control device that has the function of extracting and verifying the tenant number of the calling/incoming mobile subscriber, billing can be done using registration pulses from the local exchange.
In addition, billing control such as no billing can be performed, and excellent effects such as no need to install a new billing device can be achieved.
