Description

METHOD AND APPARATUS FOR SEPARATING BILLING OF USER EQUIPMENT BASED ON STATE OF EQUIPMENT}

The present invention relates to a charging separation technique of a communication terminal for a mobile communication, and more specifically, the cause of occurrence when a call is disconnected in a Voice of LTE (Volte) network including an Evolved-UMTS Terrestrial Radio Access Network (E-UTRAN) It relates to a terminal state-based charging separation method and apparatus suitable for subtracting the time required for call disconnection detection based on the call charging of the terminal.

As is well known, 3GPP Release 8 describes one of the mobile communication systems, EPC (Evolved Packet Core), which is a network architecture, and EPC is a network for 3GPP Long Term Evolution (LTE) systems. It is a set of nodes.

These EPCs have evolved the core network of the existing 3GPP system architecture to support Evolved-UMTS Terrestrial Radio Access Network (E-UTRAN), which is an evolved ERAN (Evolved RAN), and also improve the efficiency of the packet network. It has an efficient network structure that simplifies network nodes to increase. A wireless communication system including EPC and E-UTRAN may be referred to as an Evolved Packet System (EPS), and it can be considered that the LTE mobile communication system currently in service in Korea is applicable to this.

On the other hand, in the early stage of building an LTE mobile communication system, a mixed communication environment with a legacy network such as a WCDMA mobile communication system appears. In this communication environment, a WCDMA (Wideband Code Division Multiple Access) network, etc. can be used while being able to access the LTE network. A dual mode mobile communication terminal device (communication terminal) capable of accessing the same legacy network may be operated. In addition, at the beginning of the LTE mobile communication service, a WCDMA mobile communication system was used to provide a voice call service to a dual mode mobile communication terminal device, and an LTE mobile communication system was used to provide a data communication service.

Unlike the above, it is a VoLTE service that enables data communication as well as voice calls to be realized through an LTE mobile communication system. This VoLTE service is sometimes called a high definition (HD) voice service. According to the VoLTE service, it is possible to provide a clean HD-class voice call service during a voice call, and users display a screen like a counterpart in real time during a call. While giving, you can share content such as maps, music, news, and photos.

In this LTE mobile communication system, location information of a communication terminal is managed in units of eNodeBs that function as a base station device for mobility management of the communication terminal. That is, the location of the communication terminal is managed through signaling between the Mobility Management Entity (MME) functioning as a mobility management node and the eNodeB, and the location information of the managed communication terminal is SGW for use as a billing policy or location-based service It is being transmitted to PGW (PDN Gateway) through (Serving Gateway).

On the other hand, when the call is dropped during a call between the calling terminal and the called terminal, for example, the called terminal attempts a handover to an adjacent base station due to a weak signal strength, or fails or the battery of the called terminal is detached (battery separation) In this case, the base station generates a UE Context Release Request message and transmits it to the network node to notify the call termination at the called terminal, and in response, the PGW of the network node receives the called terminal. Releases the bearer assigned to, and the charging node deducts the charging time of the originating terminal from the predetermined time required for detection of call disconnection (eg, 10 seconds, 15 seconds, 20 seconds, etc.).

Typically, it is time for the base station to determine (detect) call disconnection due to handover failure, which takes several seconds, for example, 2-4 seconds, and the base station determines (detects) call disconnection due to battery hernia. It is known that it takes 10 seconds (for example, 10 seconds, 15 seconds, 20 seconds, etc.), which may vary depending on the network environment, but the time required to determine the call disconnection due to a handover failure is a call due to battery hernia. It is well known that it is relatively shorter than the time required for cutting.

However, in the case of the conventional method, since the same call disconnection message is transmitted without providing the cause information (handover failure or battery detachment) of the call disconnection, the charging node relatively determines the reference time for subtracting the time required to detect the call disconnection. Therefore, it is set as a long deduction time that is sufficient to cover the time required by a long battery hernia, and the long deduction time set in the call charging of the calling terminal is deducted every time a call is disconnected.

As described above, regardless of the cause of call disconnection, applying a relatively long deduction time to currency billing whenever call disconnection occurs acts as a major factor in reducing the reliability of currency billing. It is a factor that causes disadvantages to operators by partially omitting billing for.

Moreover, considering the reality that call disconnection due to handover failure is much more frequent than call disconnection due to battery hernia, the reliability of currency billing and the disadvantage of operators are inevitable.

Republic of Korea Registered Patent Publication No. 10-0879851, registration notice date January 22, 2009.

It provides a terminal state-based billing separation device including a generating unit and a message sending unit for transmitting the generated release request message to a charging node for selective subtraction of currency billing.

According to another aspect of the present invention, a process of receiving a release request message including call disconnection identifier information from a network and whether call disconnection is a first call disconnection due to handover failure through analysis of the call disconnection identifier information Or a process of determining whether the second cut is due to a hernia, and a process of selectively subtracting the time required for the detection of the first cut or the second cut in the call charging of the calling terminal according to the determination result It provides a terminal state based charging separation method comprising a.

Application service node (TAS: Telephony Application Server) in the IMS (IP Multimedia Subsystem) network that provides additional services such as switching, subscriber registration, authentication, billing, triggering and routing for each service, callee location inquiry, call processing, and SIP-based A call session control function (CSCF) that performs a basic function for multimedia session control or the like may be applied as a charging node.

Next, a series of processes for selectively applying the deduction of currency billing according to the cause of call disconnection according to the present invention using the mobile communication service system having the above-described configuration will be described in detail.

3 is a flowchart for explaining a process of selectively applying a deduction of currency billing according to a cause of call disconnection when a call disconnection occurs according to the present invention.

Referring to FIG. 3, the first terminal state management unit 202 in the base station 104 determines whether call disconnection (first call truncation) occurs due to a handover failure event from two terminals (called terminal and called terminal) in a call. Whether to monitor, and the second terminal status management unit 204 monitors whether a call disconnection (second call disconnection) event due to a battery hernia occurs from two terminals (called terminal and called terminal) in a call.

As a result of the monitoring, when it is determined that the first call or the second call is cut (step 302), the message generating unit 206 releases a request message including call cut cause information (for example, in handover failure). UE Context Release Request message including first call disconnect identifier information (Handover Failure), which means call disconnection, or second call disconnect identifier information (UE Lost), which means call disconnection due to battery hernia. )), And generates a UE Context Release Request message), and the message sending unit 208 transmits the generated release request message to the mobility management node 106 (step 304).

In response to this, the mobility management node 106 receives the UE Context Release Request message including the first call split identifier information or the second call split identifier information from the base station 104, and deducts the associated bearer and deducts it from charging. To generate a bearer deletion command message (Delete Bearer Command (w / o or w / Private Ext)) including a message for application, for example, call disconnection cause information (1st call delimiter information or 2nd call delimiter information), A bearer deletion command message (Delete Bearer) that transmits to the signal processing node 108 (step 306), and the signal processing node 108 includes call disconnection cause information (# 1 call delimiter information or # 2 call delimiter information). Command (w / o or w / Private Ext) is transmitted to the packet processing node 110 (step 308).

Next, in the packet processing node 110, a bearer deletion command message (w / o or w / Private Ext) including call truncation cause information (first truncation separator information or second truncation separator information) ) Is received, a message including a corresponding call disconnection reason code (e.g., code 10 or code 15) is generated (e.g., a CCR-U (RULE_STATUS Failure Code 10 or 15) message) to generate a policy management node 112 Is sent (reporting the cutting cause) (step 310), and the bearer allocated to the corresponding terminal is released (deleted) (step 312).

Subsequently, when the policy management node 112 receives a CCR-U (RULE_STATUS Failure Code 10 or 15) message including the call truncation reason code from the packet processing node 110, the call truncation cause information is provided according to the prescribed charging policy. An included call blocking request message (eg, Abort Session Request (Cause: 0 or 1)) is generated and transmitted to the multimedia session control node 114 (step 314).

In response, the multimedia session control node 114 generates a call release message (for example, a Session Initiation Protocol (SIP) Bye) corresponding to the call blocking request message and transmits the call connection to the two terminals by transmitting it to the network node side. Release (step 316).

In addition, the multimedia session control node 114 applies the result of the analysis of the cause of the call disconnection to the billing of the corresponding terminal, for example, a call indicating the first call disconnection (call disconnection due to handover failure) from the call blocking request message. When the cut cause code (No. 1 cut separator information) is extracted, the preset first reference time required (for example, 2-4 seconds, etc.) is deducted from the corresponding terminal billing, or the No. 2 cut from the call blocking request message When the call disconnection cause code (No. 2 cut separator information), which means (Call cut due to battery hernia), is extracted, it corresponds to the preset second reference time (e.g., 10 seconds, 15 seconds, 20 seconds, etc.) Subtraction is applied to the charging of the terminal (step 318).

That is, when the multimedia session control node 114 receives a release request message including call disconnection identifier information from the network, through analysis of the call disconnection indicator information, whether the call disconnection is the first call disconnection due to a handover failure or battery detachment It is determined whether or not the second call is cut, and the time required for the detection of the first call or the second call is selectively subtracted from the call billing of the calling terminal according to the determination result.

In other words, the present invention subtracts from the call charging of the corresponding terminal a predetermined reference time required corresponding to the time actually spent in determining and detecting the call disconnection according to the cause of the call disconnection.
