Description

Call processing method for transmitting calling number in communication network

According to the present invention, when an exchange requests a called party to answer a call setting request of a calling party, but the called party does not respond, the exchange sends an announcement to the calling party so that the calling party can leave the calling party's phone number. It relates to a call processing method.

1 is a flowchart illustrating a conventional general call processing method.

First, when the mobile communication system receives an incoming call request message requesting an incoming call from a specific subscriber in an initial state (dwell state) 11 in which a call connection is not made (12), the mobile communication system moves the location area where the called subscriber is located. In step 13, paging is performed in the corresponding location area. Upon receiving a response from the mobile terminal according to the paging request (14), it transmits to the calling party that the incoming call is occupied (15) and allocates a radio traffic channel for establishing a call (16). When the allocation of the wireless traffic channel is completed, the mobile terminal transmits an alerting signal to the mobile terminal to request the incoming subscriber to set up the incoming signal (17), and then transitions to the response waiting state for receiving a response from the called party (18). . When the incoming response is received from the called subscriber who receives the alerting signal in the answer waiting state 18 (19), a busy state is established and a call connection is made between the calling party and the called party (20). If the called party does not answer while the ring timer is activated in the response waiting state 18, a ring timeout occurs (21), and the mobile communication system which receives it reports to the calling party that the incoming call has failed (22). After the termination process for releasing various resources of the system is performed (23), the system transitions to the initial state (11).

In the conventional mobile phone call processing method as described above, when the called party does not answer, the mobile communication system performs a failure process for the corresponding call, and at this time, a failure indicating that an unanswered call is generated in the called party's mobile terminal The number of calls is indicated by a mobile terminal internal function. Therefore, the called party can recognize that the incoming call has occurred, but can not know the information about the calling party, and there is no way for the calling subscriber to notify the called party of his call attempt. In addition, in terms of network operation, there is a problem in that billing cannot be made even though network resources are used for call setup because the incomplete call must be treated as an incomplete call.

In order to solve the above problems, the present invention, in response to the call set-up request of the calling subscriber, but the incoming subscriber requests a response, but the incoming subscriber does not respond, the exchange transmits the announcement to the calling subscriber to the calling subscriber. By entering the telephone number, the telephone number of the calling subscriber is displayed on the terminal of the called subscriber, so that subsequent call connection attempts can be made according to the will of the called subscriber, and the call processing is made so that the incoming call can be processed for the unanswered call. The purpose is to provide a method.

In order to achieve the above object, the present invention provides a call processing method applied to a communication system, in which only a called party is released if there is no response from the called party for a first predetermined time when the call is set up according to the called party's call occupancy request. A first step of causing the calling party to input a predetermined number and at the same time transitioning to a reception standby state for receiving the predetermined number; A second step of converting the received predetermined number into a data message and transmitting it to the called party after starting charging when the predetermined number is received in the reception standby state; A third step of terminating call processing after finishing charging if a call release request according to a call disconnection of a calling party is received in the reception waiting state; And a fourth step of terminating the call processing if the predetermined number is not input from the calling party during the second predetermined time in the reception standby state.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention;

2 is a configuration diagram of an embodiment of a mobile communication system to which the present invention is applied, where "31" is a home location register, "32" is a mobile switching / visitor location register, "33" is a base station, and "34" is The mobile terminal "35" represents a general public telephone network, respectively.

The mobile terminal 34 is a terminal device having a unique number (phone number) and carried by a subscriber, and the base station 33 is a mobile terminal 34 in a wireless communication section between the mobile terminal 34 and the mobile switching center 32. It is a device that can transmit a radio signal to or receive a radio signal from the mobile terminal 34.

The mobile exchanger / visitor location register 32 is an exchange of the area where the mobile terminal 34 is being serviced, and stores the location and service profile of the mobile terminal 34, and performs an exchange function to connect a call path. The home location register 31 is a database that stores the location information of the mobile terminal 34 of the subscriber and the service profile information of the subscriber, and the general public telephone network 35 General fixed line telephone network.

On the other hand, the visitor location register 32 may be located outside or inside the mobile switch 32 in some cases, and the home location register 31 may be configured outside or inside the mobile switch 32 in some cases. The base station BS may be divided into a base station base station controller (BSTS) and a base station controller (BSC). Usually, a plurality of home location registers 31 may exist in one mobile communication service network, and one or more mobile switch / visitor location registers 32 may be connected to one home location register 31. Several base stations 33 may be connected to one mobile switch 32.

3A and 3B are flowcharts illustrating a call processing method for transmitting a calling number according to an embodiment of the present invention.

The present invention provides a function to allow a calling subscriber to leave a phone number or a combination of digits previously promised, such as a pager service, when a called subscriber does not answer during call processing.

First, when the mobile communication system receives an incoming call request message requesting an incoming call from a specific subscriber in an initial state (rest state) 41 in which a call connection is not made (42), the mobile communication system determines a location area where the called subscriber is located. In step 43, paging is performed on the location area. Upon receiving a response from the mobile terminal according to the paging request (44), it transmits to the calling party that the incoming call is occupied (45) and allocates a wireless traffic channel for establishing a call (46). When the allocation of the wireless traffic channel is completed, an alerting signal is transmitted to the mobile terminal to request the incoming subscriber to set up the incoming call (47), and then transitions to the response waiting state for receiving a response from the called party (48). . When the incoming response is received from the incoming subscriber who receives the alerting signal in the answer waiting state 48 (49), a busy state is established and a call connection is made between the calling party and the called party (50).

On the other hand, if the incoming subscriber does not respond while the ring timer is activated in the response waiting state 48, a ring timeout occurs (51), and the mobile communication system receiving the received mobile station performs normal release processing for the incoming mobile terminal ( 52) The calling party transmits an announcement to input the calling subscriber's telephone number (53). In order to receive the announcement and simultaneously receive the telephone number inputted by the calling subscriber, the DTMFR (Dual Tone Multi-Frequency Receiver) is connected (54), and the call is transferred to the calling number receiving state (55). At this time, the announcement broadcast and DTMFR connection may be performed by an additional device such as a mobile switching center or a voice mailbox (VMS / IVR). A call subscriber who fails to set up an incoming call has the same effect as a call that he attempted to connect to the pager automatically (transferring). Enter a number.

On the other hand, when the caller receives the phone number entered by the calling subscriber in the caller ID receiving state (55) (56), it is determined whether the phone number is the first digit (57) and if the first digit is started, the billing for the call is started. (58) It is determined whether it is the last digit (59), and if it is not the first digit, it is determined whether it is the last digit (59). In general, the billing details are recorded at the calling party, and the called party transmits an incoming response signal to the calling party so that billing can be performed. In addition, the mobile communication system includes a function of checking whether the received telephone number is the last digit, and generally uses a special number such as "*" or "#" as the last digit or a method by timeout of a number input timer. Can also be used. If the input digit is not the last digit, it transitions to the calling number reception waiting state 55 to continuously receive all the telephone numbers. If the input digit is the last digit, the DTMFR connection is released (60), and the telephone number entered by the calling subscriber is generated as a data message and transmitted to the mobile terminal (61). At this time, the data message is generated by the wireless access standard used in the corresponding mobile communication system and transmitted to the mobile terminal. In a typical 800 MHz code division multiple access (CDMA) mobile communication system, the data burst message according to the IS-95 standard (Data Burst) Message or Feature Notification Message may be used as the data message. In general, in order to transmit text information to a subscriber in a code division multiple access (CDMA) mobile communication network, a mobile terminal and a short message center that allow the IS-637 standard are used, but the method according to the present invention is applied. In this case, it is not necessary to introduce additional equipment into the existing network, and it is possible to provide a service even for a mobile terminal to which the IS-637 standard is not applied.

In addition, the mobile communication system transmits the generated data message to the mobile terminal, and then receives the call release request generated by the calling subscriber after completing the phone number input and cutting the call in the caller ID receiving wait state 55 (62). In the same way as the general call, the charging termination procedure is performed (63), and after the release of the various resources related to the call, the state transitions to the initial state (41). At this time, the charging record is generally performed at the calling party (calling exchange, calling process).

On the other hand, the mobile communication system releases the DTMFR connection and releases various resources related to the call if the timeout occurs from the timer inside the system without inputting the telephone number from the calling party in the caller ID receiving status (55). After (66) it transitions to the initial state.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

The present invention as described above, by displaying the telephone number entered by the calling subscriber on the terminal of the called subscriber, can solve the question about the call that the incoming subscriber did not respond, and if desired, can immediately try to set up the call . In addition, although the call connection is not made from the caller's point of view, a method for notifying the call subscriber of his / her own view is provided so that the existing inconvenience can be eliminated, thereby increasing the convenience of the service subscriber. On the other hand, from the standpoint of the telecommunications network operator, when a calling subscriber enters a phone number, it can be processed as a completed call, so that billing for network resources used to set up a call becomes possible, and the call subscriber does not answer the call again. If you try to do this, the sales increase accordingly, and also in terms of network management, the completion rate of the call can be improved.
