After reassembling the call access packet and transmitting the call to the calling subscriber terminal, the packet call is established between specific subscriber terminals by transitioning the calling subscriber matching terminal and the called subscriber matching unit to the data transmission state.

Therefore, when the packet call is established as described above, the desired packet data communication is performed between the set source and destination subscriber stations, and such packet communication is performed when the call release request packet and the release acknowledgment packet are generated (i.e., transmit and receive). The call setup is released. In this case, the exchange system checks whether the subscriber (user) who requested the packet release is subject to charging when the packet call release is required. When it is determined, the call charge according to the call is allocated to the subscriber (user) to whom the fee is added among the called subscribers, and the charge charged in the separate charge data storage means is stored.

On the other hand, the conventional packet-switched communication method as described above does not have a function of notifying (services) to the subscriber (user) of the fee charged to the user according to the call, and therefore, if the subscriber wants to know this, the exchange station I could only find out by visiting the (telephone office) or accepting complaints. In other words, the conventional packet switched communication method has no service function for charging information, and thus, a subscriber who wants to know this has to suffer a lot of inconveniences, which is a serious obstacle to providing a truly improved service.

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a schematic block diagram of an exemplary packet switching system suitable for servicing packet charging information at a switch in accordance with the present invention.

As shown in the figure, a typical packet switching system includes an outgoing subscriber matching unit 102, an outgoing packet processing unit 104, a receiving subscriber matching unit 106, an incoming packet processing unit 108, a packet path control unit 110, and The path analyzer 112 is included.

Referring to Figure 1, the outgoing subscriber matching unit 102 performs a matching function with the calling subscriber terminal requesting a call. At the same time as notifying the control unit 110, the call request packet information is transmitted to the outgoing packet processing unit 104 through the physical path for data transmission set by the packet path control unit 110.

Next, the outgoing packet processing unit 104 processes the call request packet information provided by the outgoing subscriber matching unit 102 and delivers it to the subscriber matching device to be delivered, that is, the call request packet is transmitted from the outgoing subscriber matching unit 102. When received, it decomposes the received call request packet, checks the contents of service requested by the subscriber (user), verifies whether the contents can attempt a packet call to the called subscriber, and converts the verified call request packet into an incoming packet. It reassembles and delivers the received packet processing unit 108 through the physical path for data transmission set by the packet path control unit 110.

Further, when the incoming packet processing unit 108 receives the call connection packet, the outgoing packet processing unit 104 decomposes the received call connection packet and verifies, that is, verifies through the packet path control unit 110, and transmits the set data. The verified call connection packet is transmitted to the originating subscriber matching unit 102 through the physical path for the call.

On the other hand, the packet path control unit 110, although the detailed illustration in the same figure is omitted, it is substantially composed of a part for controlling the outgoing path and the part for controlling the incoming path, in the outgoing subscriber matching unit 102 When the reception status of the call request packet is notified, a physical path (data transmission path) between the call subscriber matching unit 102 and the call packet processing unit 104 is established (that is, the call packet processor is allocated) and the call request packet is verified. In order to extract the called number and the service request from the call request packet provided by the outgoing packet processing unit 104, and forwards the extracted called number to the path analysis unit 112. In addition, the packet path control unit 110, based on the destination subscriber position information (relay line in the case of a relay call) provided by the path analysis unit 112, physically between the destination subscriber matching unit 106 and the destination packet processing unit 108. Set up the route (that is, assign the incoming packet handler).

Furthermore, the packet path control unit 110 receives a call reception packet according to the transmission of the incoming packet from the called subscriber station (another exchange in the case of a relay call), reassembles the call reception packet after analysis of the call reception packet, and then sends the call packet processing unit ( When provided to 104, the destination subscriber matching unit 106 and the destination packet processing unit 108 transition from the incoming state to the data transmission state, and the call connection packet verified through the outgoing packet processing unit 104 is the outgoing subscriber matching unit. Transmitting the subscriber subscriber matching unit 102 and the outgoing packet processing unit 104 from the outgoing state to the data transmission state when it is transmitted to the subscriber station (in the case of a relay call) through 102. In addition, the packet path controller 110 releases the physical path between the subscriber matching unit and the packet processing unit when a release request packet is received from the originating subscriber terminal or a release confirmation packet is received from the called subscriber station.

That is, the packet path control unit 110 has a function of setting and releasing a physical path between the calling party matching unit 102 and the outgoing packet processing unit 104 and the physical connection between the called party matching unit 106 and the incoming packet processing unit 108. Set and release path.

In addition, the packet path control unit 110, if the call request packet received from the calling party or the call receiving packet received from the called party includes the billing information notification service providing information according to the present invention, the caller or called party billing information notification service Each of the provisioning states is stored in a separate storage means, and when the packet call is released according to one of the subscriber's requests for release, the charging information charged to the subscriber to be charged is confirmed. Subscriber) or release indication packet (subscriber requested to release packet call) to control transmission.

Meanwhile, the path analyzer 112 determines the path of the packet by translating the called number, that is, translates the called number provided by the packet path controller 110 to determine the location of the called address subscriber (relay line in the case of a relay call). And the retrieved subscriber location information is transmitted to the packet path control unit 110 for the establishment of the incoming path.

On the other hand, the incoming packet processing unit 108 is transmitted to the destination subscriber matching device to process and deliver the incoming packet provided by the outgoing packet processing unit 104 described above, that is, reassembled and forwarded the received incoming packet to the calling party After verifying the service contents requested by the service provider, determining whether the confirmed service contents are acceptable to the called subscriber (other exchange in the case of a relay call), verifying them, and then reassemble them into the incoming packet, and reassemble them through the established data path. The incoming packet is delivered to the called party matching unit 106.

In addition, when the incoming packet processing unit 108 receives a call reception packet that is a response from the called subscriber station (another exchange in the case of a relay call) according to the incoming packet transmission received through the called subscriber matching unit 106, the received call is received. After disassembling and verifying the received packet, the packet is reassembled into a call connection packet and transmitted to the outgoing packet processing unit 104 through the established path.

On the other hand, the called party matching unit 106 performs a matching function with the called subscriber terminal which is requested to make a call, and when the called packet is received by the outgoing packet processing unit 108, the incoming packet received at the remote site is received. When the incoming packet is received from the remote subscriber terminal in response to the transmission of the incoming packet and the incoming call packet, which is the response of the incoming packet, is transmitted to the subscriber station, the packet path controller 110 is notified to the packet path controller 110 at the same time. The call reception packet information is transmitted to the incoming packet processor 108 through a physical path for data transmission set by 110.

Therefore, if a packet call is established through the above-described process, the packet switched communication between the calling subscriber terminal and the called subscriber terminal corresponding to the call until the call release request packet and release confirmation packet are generated (that is, transmitted and received). This will be done.

Next, a process of serving packet charging information to a subscriber in accordance with the present invention using a typical packet switching system having the above-described configuration will be described in detail.

2 is a flowchart illustrating a process of setting up a packet call according to a preferred embodiment of the present invention.

Referring to the figure, when a call request packet is received at a remote call subscriber terminal, the call subscriber matching unit 102 transmits the call request packet reception state to the packet path control unit 110 (step 202). The control unit 110 accesses the originating subscriber information from a database (not shown) and allocates the originating packet processing unit 104 and then establishes a physical path, that is, a data transmission path between the originating subscriber matching unit 102 and the originating packet processing unit 104. Set (step 204).

Therefore, the outgoing subscriber matching unit 102 transmits the call request packet received through the set data transmission path to the outgoing packet processing unit 104, and the outgoing packet processing unit 104 analyzes the transmitted request request packet information to the outgoing subscriber. Checks the called party number to which the call is desired and the service function code contained in the call request packet, and then checks the user eligibility of the calling subscriber (user) request service, that is, what kind of service is requested (step 206).

Next, the outgoing packet processing unit 104 checks whether the service function requested by the outgoing subscriber (user) has no abnormality in the call establishment requirement, and checks whether or not the service is allowed (step 208). If the service function requested by the user does not meet the establishment requirements, the call is released. If the calling requirements are met, the calling subscriber (user) who attempted the call again requested the billing information notification function or It is checked whether the billing information notification function service of all packet calls associated with the originating subscriber should be provided (step 210), and if the check result in this step 210 determines that there is a billing information notification function service, the call request is delivered. The packet path control unit 110 provides that the charging notification service is provided together with the packet. At this time, if there is no charging information notification function service as a result of the check in step 210, the process proceeds directly to step 216 to be described later.

Then, the packet path control unit 110 checks whether or not the calling subscriber is to pay (step 212), and if the check result is not the caller toll charge, processing proceeds directly to step 216 described later, and check result If it is determined that the caller is charged (charge), when the calling subscriber is determined to be subject to the charge notification service, it is stored in a separate storage means that the charge notification service is required (step 214), and the process proceeds to step 216. do.

On the other hand, in step 216, the incoming packet processing unit 108 is allocated based on the transferred request packet information, and a physical path between the allocated incoming packet processing unit 108 and the destination subscriber matching unit 106 is set. That is, the packet path control unit 110 extracts the called number from the call request packet information provided by the outgoing packet processing unit 104 and requests a translation to the path analyzing unit 112, and the path analyzing unit 112 requests the called number. To retrieve the subscriber location (another exchange in the case of a relay call) and notify the retrieved subscriber location to the packet path control unit 110. As a result, the packet path control unit 110 allocates the incoming packet processing unit 108 to the corresponding incoming call. A physical path between subscriber matching units 106 is established.

At this time, the outgoing packet processing unit 104 reassembles the verified call request packet into the incoming packet and delivers it to the incoming packet processing unit 108. The incoming packet processing unit 108 analyzes the delivered incoming packet and analyzes the service user qualification. Inspection, i.e., analysis of the incoming packet, confirms the service contents requested by the calling party and checks whether the confirmed service contents can be accommodated by the called subscriber (steps 220 and 222).

As a result of the check in the step 222, the use of the service is permitted, that is, if the service content is determined to be an unacceptable service, the called signal is released, and if it is determined that the service is acceptable, the incoming money verification packet After reassembling the UE, the received incoming packet, which has been verified through the called subscriber matching unit 106, is transmitted to the called subscriber terminal (another exchange in the case of a relay call), and waits while checking reception of a call reception packet from the called subscriber terminal (step). 224,226).

Next, when a call reception packet from the called subscriber terminal is received in the same waiting, the called subscriber matching unit 106 transfers the received call reception packet to the called packet processing unit 108, and the called packet processing unit 108. ) Checks whether the service is allowed by analyzing the forwarded call packet, that is, by checking the service function code included in the call received packet by analyzing the received call packet to recognize whether or not what kind of service is required (step). 228), the service function requested by the called subscriber (user) is checked whether or not there is no problem in the call establishment requirement, and it is checked whether or not the service is allowed (step 230).

If the service function requested by the user does not meet the call establishment requirement as a result of the check in the step 230, the caller release signal is released. If the call function meets the call establishment requirement, the receiving subscriber (user) requests the billing information notification function again. Check whether there is a billing information notification function service of all packet calls associated with the incoming or outgoing subscriber (step 232), and if it is determined that there is a billing information notification function service at this step 232, it is received. The packet path control unit 110 provides that the billing notification service is provided together with the call reception packet. At this time, if there is no billing information notification function service as a result of the check in step 232, the process proceeds directly to step 238, which will be described later.

On the other hand, the packet path control unit 110 checks whether or not it is a fee that the called party has to pay (step 234), and if the check result is not the called party's fee, processing proceeds directly to step 238 which will be described later. If it is determined that the charge is a charge (charge), when it is determined that the called party is subject to the charge notification service, it is stored in a separate storage means that the charge notification service is required (step 236), and the process proceeds to step 238. .

Next, when the incoming packet processing unit 108 reassembles the verified information into the call connection packet and transmits the verified information to the outgoing packet processing unit 104, the packet path control unit 110 communicates with the called party state, that is, the incoming packet processing unit 108. The incoming state of the called party matching unit 106 is transferred to the data transmission state (step 238).

The outgoing packet processing section 104 then disassembles and verifies the call connection packet delivered from the incoming packet processing section 108, reassembles the verified packet, and then requests the first call through the outgoing subscriber matching section 102. Transmits to one calling subscriber terminal, and when the packet path control unit 110 completes the call connection packet transmission, the calling party state, that is, the calling state of the outgoing packet processing unit 104 and the outgoing subscriber matching unit 102 transitions to the data transmission state. (Step 240), the packet call setup process executed according to the present invention is terminated.

Therefore, the packet call having the packet charging information service function according to the present invention is established through the above-described process, so that packet communication (packet data transmission and reception) between the calling party requesting the call and the target called party requesting the call is performed. will be.

Next, when packet communication is established between the calling subscriber and the called party by setting up the packet call through the above-described process, the packet call set for packet communication is released according to the release request of one of the subscribers who want to terminate the communication. The process of doing so will be explained.

3 is a flowchart illustrating a process of releasing a set packet call according to a preferred embodiment of the present invention.

Referring to the figure, a subscriber request unit 102 or 106 releases a request for release of a packet call from one of two subscribers (i.e., the originating subscriber and the called party) while the packet call is established. When received, the subscriber matching section 102 or 106 notifies the subscriber's packet processing section 104 or 108 that a release request has been received (step 302). Then, in step 304, the packet processing unit 104 or 108 of the subscriber who has requested the packet call release informs the packet processing unit 108 or 104 of the subscriber side that the packet call release request has been received.

Next, the packet processing unit 104 or 108 transfers the charging information and the talk time information collected in the data transfer state to the packet path control unit 110 (step 306). Therefore, the packet path controller 110 checks whether the corresponding subscriber is subject to charge (step 308), and if the subscriber is determined to be charged, the charge data is stored in the storage means (not shown) (310). In the above-mentioned packet call setup process, whether the subscriber who has requested (or verified) the request for the release of the packet call based on the subscriber notification target subscriber information previously stored (or verified) according to the subscriber's request is the subscriber who requested the provision of the charging information notification service. Check (step 312).

As a result of the check in step 312, if it is determined that the subscriber who requested the packet call release is the subscriber who requested the provision of the charging notification service, the packet path control unit 110 issues a release confirmation packet transfer command together with the supplementary charging information. Provided to the packet processing unit 104 or 108, and as a result, the packet processing unit 104 or 108 assembles the release confirmation packet including the charging information (step 314), and then the assembled release confirmation packet (including the charging information). Is transmitted to the subscriber who requested the packet call release through the subscriber matching unit 102 or 106 (step 318), and the packet matching unit 102 or 106 and the packet processing unit 104 or 108 are sent by the packet path control unit 110. Packet paths (data delivery paths) between are removed (step 320).

On the other hand, the subscriber who requested the check result packet call release in step 308 is not subject to charge, or the subscriber who requested the check result packet call release in step 312 requests the billing notification service to be provided. If it is determined that the subscriber is not a subscriber, the packet path control unit 110 provides a release confirmation packet forwarding command having no charging information to the packet processing unit 104 or 108, and as a result, the packet processing unit 104 or 108 provides the charging information. Assembling the release confirmation packet does not include (step 316), and then processing proceeds to step 318 described above to perform the same process.

Accordingly, the subscriber matching unit 102 transmits a release acknowledgment packet including or not charging information to the subscriber who requested the packet call release during the packet communication between the two subscribers through the above-described process, and requested the packet call release. Or 106) and the packet path (data transfer path) set between the packet processing unit 104 or 108 is removed.

On the other hand, when the subscriber packet processing unit 104 or 108, which has requested the packet call release through the step 304, is notified of the reception status of the release request packet to the counterpart subscriber packet processing unit 108 or 104, the subscriber station packet processing unit ( 108 or 104 transmits the charging information and the talk time information collected in the data delivery state to the packet path control unit 110 (step 324). Accordingly, the packet path control unit 110 checks whether the corresponding subscriber (the subscriber who is requested to release the packet) is subject to charge (step 326), and if the subscriber is determined to be charged, the packet path control unit 110 The subscriber receives the charge data by storing the charge data (328), and is requested (or verified) according to the subscriber's request in the above-mentioned packet call setup process and requested to release the packet call based on the subscriber notification target subscriber information previously stored in the storage means. It is checked whether the subscriber is requested to provide the information notification service (step 330).

As a result of the check in the step 330, if it is determined that the subscriber who has been requested to release the packet call is the subscriber who has requested the provision of the charging notification service, the packet path controller 110 issues a release instruction packet transfer command together with the supplementary charging information. Provided to the packet processing unit 108 or 104, and as a result, the packet processing unit 108 or 104 assembles the release instruction packet including the charging information (step 332), and then the assembled release instruction packet (including the charging information). ) Is transmitted to the subscriber who has been requested to release the packet through the subscriber matching unit 106 or 102 and waits for reception of the release confirmation packet from the subscriber station which has been requested to release the packet call (step 336).

In addition, the subscriber who is requested to release the packet call as a result of the check in step 326 is not charged, or the subscriber who is requested to release the packet call as the result of the check in step 330 requests the billing notification service to be provided. If it is determined that the subscriber is not a subscriber, the packet path control unit 110 provides a release instruction packet transfer command without charging information to the packet processing unit 108 or 104, and as a result, the packet processing unit 108 or 104 provides the charging information. In step 334, the processing proceeds to step 336, and performs the same process of delivering the assembled release instruction packet to the subscriber matching unit.

On the other hand, when the release acknowledgment packet is received from the subscriber station requesting the release of the packet to the subscriber matching unit 106 or 102, the packet processing unit 108 or 104 receives the release state of the release acknowledgment packet. 110 (step 338), the packet path controller 110 removes the packet path (data transfer path) between the subscriber matching section 106 or 102 and the packet processing section 108 or 104 (step 340).

As a result, during the packet communication between the two subscribers, as described above, the subscriber matching unit which transmits a release acknowledgment packet including or without charging information to the subscriber who is requested to release the packet call and receives the packet call release ( 106 or 102 and the packet path (data transfer path) set between the packet processing unit 108 or 104 are eliminated.

As described above, according to the present invention, when a user wants to find out his billing state (charge state) according to packet communication, the subscriber requesting the call or the subscriber who requested the call through the above-described process are seen.
