Description

Subscriber ring-back tone length adjustment method}

The present invention provides a method for adjusting the length of a call waiting tone for each subscriber and a program for realizing the method, which can vary the length (provided time) of call waiting sound (ring back tone) for each called party in a wireless communication system. The present invention relates to a recording medium which can be read by.

In general, in a wireless communication network, when a calling party calls a called party, it provides a processing tone to notify the calling party that the calling party is paging the called party, and when it receives a response to the paging request, it calls the called party. Give ringback tone to callee to indicate that it is present. Then, when the called party receives the response, it releases the processing tone and ringback tone that were provided to the calling party.

As the related art related to the ringback tone, an advertisement or a specific file (music, melody, greeting, etc.) desired by an incoming subscriber is replaced with a ringback tone to improve a uniform ringback tone method or to provide a ringback tone to a subscriber quickly. There is a description of the method, but there is no way to adjust the time (adjust the ringback tone length) to provide the ringback tone for each subscriber.

However, in the present wireless communication network, when the called subscriber does not answer when providing the ringback tone, the ringback tone is uniformly provided only for a predetermined time period and connected to the voicemail box (VMS). This is to prevent unnecessary waste of radio resources, because the wireless communication provider provides the subscribers with the radio resources shared by a plurality of subscribers during the time of providing the ringback tone, but does not charge correspondingly.

However, in the case of the subscriber, the ringback tone providing time is too short compared to the landline telephone, which may cause the subscriber to listen to the telephone ringing and take out the mobile terminal (MS) from the bag, and may be connected to the voicemail box to receive the necessary call. In addition, the calling party needs to make a redial for a call or leave a message in a voice mail box, thereby paying an unnecessary call fee. However, in the case of wireless communication providers, increasing the ringback tone providing time uniformly wastes frequency resources used by a large number of users. In particular, it is more difficult to increase the ringback tone providing time when there is no response even in the urban area where subscribers are busy.

On the other hand, when the called party does not respond, the time to provide ringback tone (ringback tone length) can be adjusted in the network management center (NMS), but this can be adjusted only in the unit of exchange, so that all terminals received through the exchange can be controlled. There is no choice but to provide ringback tones for a fixed amount of time.

In summary, in the current wireless communication environment, when a called party does not answer, it provides a ringback tone for a relatively short time compared to a landline, and then accesses a voicemail box. The reason for this is a method for efficiently using the radio resources shared by the users, and this is applied to all the subscribers uniformly, thereby becoming a dissatisfaction factor for the subscribers. Therefore, there is an urgent need for a method that can solve the dissatisfaction of the subscriber and the efficient use of radio resources by varying the time for providing the ringback tone for each subscriber (by adjusting the ringback tone length).

The present invention has been proposed in order to meet the above-mentioned demands. In the wireless communication system, the length of the call waiting ring (ringback tone) (provided time) is different for each called party to efficiently use radio resources and to satisfy subscribers' complaints. SUMMARY OF THE INVENTION An object of the present invention is to provide a method for adjusting the length of call waiting sound for each subscriber that can be eliminated, and a computer-readable recording medium having recorded thereon a program for realizing the method.

The method of the present invention for achieving the above object, in the method of adjusting the call waiting sound (ringback tone) length (delivery time) in the communication system, if the subscriber does not respond to the subscriber profile to the subscriber profile is connected to the voicemail A first step of setting ringback tone provision time (call-waiting tone length) information up to < RTI ID = 0.0 >; A second step of, by the calling exchange, providing the ringback tone providing time information to the called exchange when the called party calls in response to a call connection request from a calling party; A third step of the called exchange calling the called party, setting a ringback tone timer value based on the ringback tone providing time information, and transmitting a ringback tone to the calling party; And a fourth step of transmitting, by the ringback tone timer, ringback tones only within a ringback tone provisioning time period, and stopping the transmission of ringback tones when the ringbacktone provisioning time is exceeded.

In addition, the method of the present invention further includes a fifth step of connecting the voicemail box after performing the fourth step.

On the other hand, the present invention, in order to adjust the call waiting sound (ringback tone) length (providing time), the ring until the connection to the voice mail box when the subscriber does not respond to the subscriber profile in the subscriber profile to the communication system equipped with a processor A first function of setting back tone provision time (talk-waiting tone length) information; A second function that, when the called party calls, the calling exchange provides the ringback tone providing time information to the called exchange upon the call connection request from the calling party; A third function of the called exchange calling the called party, setting a ringback tone timer value based on the ringback tone providing time information, and transmitting a ringback tone to the calling party; And by the ringback tone timer, a program for realizing a fourth function of transmitting a ringback tone only within a ringback tone providing time range and stopping the ringback tone transmission when the ringback tone providing time is exceeded. Provide a record carrier.

The present invention also provides a computer-readable recording medium having recorded thereon a program for further realizing a fifth function for connecting a voicemail box after performing the fourth function.

The present invention relates to a method for differently allocating ringback tone providing time until a subscriber connects to a voicemail box in a wireless communication environment for each subscriber, and is uniform when the subscriber does not respond in a wireless communication environment. Improve the existing method of connecting ring voices after exporting a certain number of ring back tones and connecting them to voice mails by varying the time for providing ring back tones according to a predetermined value for each subscriber. To provide differentiated subscriber-based services.

To this end, the present invention sets the information on the subscriber in the subscriber profile of the location register (HLR, VLR), voice call only if the called subscriber does not respond in the situation that the calling subscriber called the called subscriber By varying the ringback tone providing time until connection to each subscriber according to the set profile, it is possible to efficiently use radio resources and increase subscriber satisfaction.

In other words, by adding a specific field to the subscriber registration information of the location register (HLR / VLR), the incoming subscriber registers or the phone rings instead of the voice mailbox for the time set by the subscriber class so that the subscriber rings a high quality service specialized for the subscriber. to provide.

As such, the present invention sets the ringback tone provision time differently for each subscriber before connecting to the voicemail box when the called subscriber does not respond in the wireless communication network. In other words, in case of a subscriber who has a large amount of voice call or registered separately, the ringback tone providing time is extended and connected to the voice mailbox, and in case of the subscriber who does not, the ringback tone providing time is allocated relatively short, thereby increasing the efficiency of radio resources and providing differentiation. Can provide services.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of a wireless communication system to which the present invention is applied.

A mobile station (MS) is within a range of a base station (BS), and information of the mobile station (MS) is passed through a base station (BS) and a base station controller (BSC) controlling the same. It is transmitted to the mobile switching center (MSC), and the information transmitted from the MSC is transmitted to the mobile terminal (MS) via the base station controller (BSC) and the base station (BS).

A mobile terminal (MS) is a terminal that a user can carry and communicate with, and is a cellular mobile terminal, a PCS terminal, other IMT-2000 (International Mobile Telecommunication), UMTS (Universal Mobile Telecommunication Service), and the like. Next generation mobile communication terminals, personal digital assistants (PDAs) and the like.

The message transmitted from the mobile terminal MS is connected to the exchange MSC through a base station BS and a base station controller BSC for high frequency signal processing and call processing.

The base station (BS) connects the mobile terminal (MS) to the base station controller (BSC), performs wireless and wireless communication with the mobile terminal (MS), and performs a wired / wireless conversion function for communicating with the base station controller (BSC) by wire. .

The base station controller (BSC) connects the base station (BS) to the switching center (MSC) to coordinate the connection between the base stations (BS), and serves as a signal processing function for communication between the base station (BS) and the exchange (MSC).

The MSC processes the mobile communication subscriber call in conjunction with the Visitor Location Register (VLR), the Home Location Register (HLR), and the Voice Mail Service (VMS).

The exchange MSC is connected to the base station controller BSC to perform call setup and release functions of the mobile terminal MS, and performs various functions related to call processing and additional services.

The visitor location register (VLR) is a database that temporarily stores subscriber information related to the mobile terminal (MS) while the mobile terminal (MS) is in an area controlled by the visitor location register (VLR). The information of the mobile terminal MS and the subscriber whose location has been registered is taken from the home location register HLR and temporarily stored, and is mainly mounted on the MSC.

The home location register (HLR) is a database that is connected to an exchange (MSC) and manages various types of information of mobile subscribers. The home location register (HLR) performs a function such as registration of subscriber locations in conjunction with various exchanges (MSCs), a mobile terminal (MS) and It stores subscriber's permanent information and location information, and supports various functions related to call processing and additional service by interacting with visitor location register (VLR).

Voicemail (VMS) is equipped with a physical storage device, the voice prompts and the voice is compressed and stored digitally, the message from the exchange (MSC) to analyze the voice guidance and stored voice.

However, since the wireless communication network as described above is only a technique well known in the art, detailed description thereof will be omitted here. However, a brief description will be given of the function of providing call waiting sound (ringback tone).

First, when the originating subscriber dials the called party number and dials the called party number, the originating call is transmitted to the originating exchange 12 through the originating base station 11.

Then, the originating exchange 12 allocates a call resource (eg, a call) for call processing, requests the subscriber information inquiry, and the originating subscriber is abnormal due to conditions such as illegal, outgoing call, and arrears. Determine whether you are a subscriber. As a result, if the caller is a normal caller, the called party number is transmitted to the home location register 13 to perform the caller information inquiry. As a result of the inquiry, according to the location information of the called subscriber, whether the originating exchange 12 is the same exchange or another exchange is distinguished, and in case of another exchange, the relay line is occupied.

On the other hand, after determining the legitimacy in consideration of illegality, banning call, delinquency, etc. of the called party, if it is a normal subscriber, after attempting to call the called party by the called exchange 14, a call path with the called party is established.

The destination exchange 14 then requests paging to the destination base station 15 using the location information of the called party. Thereafter, the destination exchange 14 requesting the paging sends a processing tone to notify the calling party that the calling party is sending paging. When receiving a response to the paging request, the incoming subscriber is alerted (call ringing) and sends a ringback tone to the calling exchange 12 to notify the calling subscriber. Afterwards, when the called party answers, it releases the processing tone and ringback tone being provided and transitions to the available call state. However, if there is no response from the called party, the service transitions to voicemail service through voicemail 16.

In the present invention, a specific field is added to the subscriber registration information of the location register 13 so that the incoming subscriber registers or the phone rings without being connected to the voicemail box 16 for a time set for each subscriber class. That is, the information on the subscriber is set in the subscriber profile of the location register (VLR / HLR), and the call subscriber is connected to the voicemail box 16 only when the called subscriber does not answer when the calling subscriber calls the called subscriber. The ringback tone providing time is different for each subscriber according to the set profile. At this time, when the called party does not answer, the ringback tone providing time (call waiting length) before connecting to the voicemail box 16 is different for each subscriber. After lengthening the provisioning time, the voicemail box 16 is connected, and in the case of an unsubscribed subscriber, the ringback tone provisioning time is relatively short. That is, when the ringback tone providing time (call waiting length) information is set, the ringback tone providing time is set differently according to the subscriber's credit level (for example, the amount of the call volume is small and low).

Then, with reference to Figure 2 looks at the subscriber-based call waiting length adjustment scenario according to the present invention.

First, when a calling party (wireless terminal user) dials a called party (wireless terminal user) number and performs a call for the called party number, the originating call passes through the calling base station 11 and the calling exchange 12. (201). At this time, when the call origination process is performed, each network element (base station (BS), base station controller (BSC), exchange (MSC), etc.) allocates resources for call setup.

After allocating a call resource (eg, a call) for call processing, the originating exchange 12 requests the visitor / home location register 13 to retrieve the subscriber information and then receives the requested information. If it is a normal subscriber, it requests information about the called subscriber again, and as a result, confirms whether the called subscriber is also a normal subscriber (202, 203).

That is, the originating exchange 12 requests the visitor / home location register 13 to query the calling party information, and determines whether the originating subscriber is an abnormal subscriber due to illegal, outgoing, nonpayment, or the like. As a result, if the caller is a normal caller, the called party number is transmitted to the home location register 13 to perform the caller information inquiry. As a result of the inquiry, according to the location information of the called subscriber, whether the originating exchange 12 is the same exchange or another exchange is distinguished, and in case of another exchange, the relay line is occupied.

Here, the subscriber profile of the visitor / home location register 13 is connected to the voicemail box 16 only when the called subscriber does not respond in the situation where the calling subscriber calls the called subscriber in addition to the information on the subscriber. Ringback tone provision time information is recorded so that the caller / home location register 13 requests incoming / outgoing subscriber information from the originating exchange 12, and the incoming / outgoing subscriber information inquiry result is received. It provides the subscriber's ringback tone provision time (length) information together (203).

Then, the originating exchange 12 connects the voicemail box 16 when the information inquiry result of the calling / receiving subscriber is not a normal subscriber (rates of late, missing number, call forwarding setting, etc.), thereby providing a normal service to the subscriber. Inform the impossible.

However, if the information inquiry result for the calling / called subscriber is the normal subscriber, the originating exchange 12 attempts to call the called party to the called exchange 14 (204) and establishes a call path with the called subscriber (205). When calling the called party, the recipient ringback tone provision time (length) information is provided together.

That is, the originating exchange 12 receives the information related to the ringback tone providing time (length) at the time of non-response to the subscriber when requesting the information on the called party, and at the call of the called party 204, the destination exchange 14 Notify by.

Then, the destination exchange 14 sets a maximum time or number of times to provide a ringback tone when the destination subscriber is unresponsive by driving a timer and simultaneously performs paging to the destination base station 15 using the location information of the destination subscriber. Request 206, and the destination exchange 14 requesting the paging sends a processing tone to inform the calling party that it is sending paging to the called party. When receiving a response to the paging request (207), the ringing tone is sent to the calling exchange 12 that the called party is being alarmed (phone ringing) (208) to notify the calling party (209).

If, during the ringback tone transmission, the called party responds (210), releases the processing tone and ringback tone being provided and connects the call path (211). When the call ends, the call resource is released.

However, if the called party does not answer, the destination exchange 14 continues to send the ringback tone until the set time or number of times by driving the timer, and then the call ends when the timer expires after the set time or number of times. After connecting to the voicemail box (212), when the call is terminated releases the call resources and maintains the standby state.

Now, the process of FIG. 2 will be described with reference to FIG. 3.

3 is a flowchart illustrating a method for adjusting a call waiting sound length for each subscriber according to the present invention.

As shown in Figure 3, according to the present invention, the method for adjusting the call waiting sound (ringback tone) providing time (length) for each called party, first, the calling party (wireless terminal user) dials the called party (wireless terminal user) number ( When a call is made to the called party by dialing (301), each network element (base station (BS), base station controller (BSC), exchange (MSC), etc.) allocates resources for call establishment ( 302).

As such, after allocating a call resource (eg, a call) for call processing (302), the originating exchange 12 requests the visitor / home location register 13 to retrieve the subscriber information and then receives the requested information. As a result, if the calling subscriber is a normal subscriber, it requests information about the called subscriber again, and as a result, confirms whether the called subscriber is also a normal subscriber (303).

At this time, since the ringback tone providing time information is recorded in the subscriber profile of the visitor / home location register 13, the visitor / home location register 13 is called when the request for inquiring outgoing / receiving subscriber information from the originating exchange 12 is requested. The ringback tone providing time (length) information of the called party is provided along with the receiving subscriber information inquiry result.

As a result of the check, if the information inquiry result about the calling / receiving subscriber is not a normal subscriber (toll late, missing number, call forwarding setting, etc.), the calling exchange 12 connects the voicemail box 16 (312) to the corresponding subscriber. Informing the public that normal service is not available. Then, if the voicemail service is terminated (313), the call resources are released (310) and maintains the standby state.

As a result of the check, when the information inquiry result of the calling / receiving subscriber is the normal subscriber, the originating exchange 12 attempts to call the called party to the called exchange 14 (304) and establishes a call path with the called subscriber. When the incoming / outgoing subscriber information is searched, the ringback tone providing time (length) information (subscriber grade information) of the called party received with the inquiry result from the visitor / home location register 13 is provided together.

Then, the destination exchange 14 sets a maximum time (for example, 30 seconds) or the number of times (for example, 10 times) to provide a ringback tone when the called party is unresponsive by referring to the subscriber profile. 305, a paging request is made to the destination base station 15 by using the location information of the called subscriber, and the destination exchange 14, which has requested the paging, processes a processing tone to inform the calling subscriber that paging is being sent to the called party; Send the. When receiving a response to the paging request, the destination exchange 14 sends a ringback tone to the originating exchange 12 that the incoming subscriber is alarming (call ringing) 306 to inform the calling party.

If, during the ringback tone transmission (306), when the called party answers (307), the ringback tone is released from the processing tone being provided and connected to the channel (308), the call is terminated (309) Releases the resource (310) and maintains the standby state.

However, if the called party does not respond (307), the destination exchange 14 continues to send the ringback tone until the set time or number of times by driving the timer (306) and the timer exceeds the set time or number of times. When it ends (311), only then connects the call to the voicemail box (312), and when the call ends (313) releases the call resources (310) and maintains the standby state.

The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes can be made in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

The present invention as described above, by simply adding a field to the location register and notifying the information to the destination exchange, if the incoming subscriber is unresponsive, the call waiting sound (ringback tone) can only be transmitted for a uniformly short time. As a result, it is possible to efficiently use radio resources and to provide subscriber-based specialized services.
