Description

Notification service method and system for data service impossibility in mobile communication network {METHOD AND SYSTEM FOR NOTICING DATA SERVICE DISALLOWANCE IN MOBILE TELECOMMUNICATION NETWORK}

The present invention relates to a method and system for providing a data service unavailable notification service in a mobile communication network, and more particularly, to a subscriber's reason (for example, payment of late payment, loss of a terminal, and exhaustion of balance in a prepaid service) The present invention relates to a method and a system for notifying of a data service impossible in a mobile communication network, in which a subscriber is informed of a reason for data service failure when a data service cannot be provided.

As the mobile communication industry developed, various value-added services were generated according to the needs and service needs of numerous customers, and service management and customer management became essential.

In the current mobile communication network, a situation may arise in which the service request cannot be properly tuned due to the subscriber's reason. If this happens in the case of a voice call service, an answering machine (ARS) or exchange will inform the subscriber of the specific reason.

However, if you use data services such as wireless Internet, multimedia message service (MMS), dial-up networking, etc., you may be able to pay late fees, report lost terminals, run out of balance on prepaid services, subscribe to wireless data blocking services, and terminal browsers. Even if there is a reason why the data service cannot be provided (data service impossible reason) such as a connection setup error, the method of informing the corresponding subscriber is extremely limited.

For example, in case of late payment, a subscriber who is not aware of this will try several times to use the wireless data service but will be refused once and for all. Eventually, the subscriber will know, via the customer center, that the wireless data service has not been provided due to late payment. If the subscriber was informed of the reason that the network could not be synchronized, the subscriber would have been able to resolve the problem quickly, without going through an unnecessary process (eg, contacting a customer center).

In addition, if the subscriber who is refused data service due to the late payment fee repeatedly performs the same data service request, there is a problem that the same process is repeatedly performed unnecessarily on the network side.

In the prior art as described above, if a data service is not provided due to a subscriber's reason, the specific reason for the data service (not possible data service) is not informed to the subscriber, so the subscriber side repeatedly performs unnecessary service requests or grasps a situation. In order to solve the problem, there is a problem that a cumbersome process must be performed, and an unnecessary countermeasure must be repeated in terms of network utilization or management. It is an object of the present invention to solve this problem.

The objects of the present invention are not limited to the above-mentioned objects, and other objects and advantages of the present invention which are not mentioned above can be understood by the following description, and will be more clearly understood by the embodiments of the present invention. Also, it will be readily appreciated that the objects and advantages of the present invention may be realized by the means and combinations thereof indicated in the claims.

In order to solve the above object, when the mobile communication network cannot provide the data service due to the subscriber's reason, the subscriber is informed of the reason for the data service failure.

More specifically, the present invention provides a method for providing a data service unavailable notification service in a mobile communication network, the method comprising: checking whether there is a data service impossible reason due to a corresponding subscriber for a mobile terminal requesting a data service; And notifying the reason why the data service is not available to the mobile terminal, if the reason for the data service unavailable exists.

In addition, the present invention provides a system for providing a data service unavailable notification service in a mobile communication network, comprising: data service management means for confirming whether a data service impossible reason due to a corresponding subscriber reason exists for a mobile terminal requesting a data service; And a notification means for notifying the mobile terminal of the confirmed reason of the data service failure.

The present invention as described above, it is possible to increase the efficiency and customer satisfaction of customer management by notifying the service constraints of the subscriber and the information required by the customer (subscriber) in real time.

In addition, the present invention has an effect that can efficiently manage the network by preventing unnecessary traffic usage in terms of the network.

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

FIG. 1 is a diagram illustrating a network configuration of a mobile communication system to which the present invention is applied and schematically illustrates a configuration of a general packet radio service (GPRS) network.

The network to which the present invention is applied includes 2G (Global System for Mobile Communications) 2G radio access networks, 2.5G GSM and Code Division Multiple Access (CDMA) networks, 3G UMTS (Universal Mobile) Telephone system and wideband code division multiple access (WCDMA) networks, other communication networks, and combinations of such networks. Since these networks are generally known, further description will be omitted. In particular, an embodiment of the present invention will be described on behalf of the case that the base station is a UMTS Terrestrial Radio Access Network (UTRAN) of the UMTS network.

As illustrated in FIG. 1, the mobile communication system 12 includes a Node B 121, a Radio Network Controller (hereinafter referred to as "RNC") 122, and a packet switching device (Serving GPRS Support Node). (Hereinafter referred to as "SGSN") 123, packet gateway device (Gateway GPRS Support Node: hereinafter referred to as "GGSN") 124, Home Location Register (hereinafter referred to as "HLR") 125, and an authentication / authorization / accounting server (hereinafter referred to as an “AAA server”) 126.

The mobile communication network shown in FIG. 1 is a network structure that complies with the general standard, and the Node-B 121 and the RNC 122 are provided in a wireless section that can guarantee free space movement of the mobile station (MS) 10. In general, a wired section, GPRS (General Packet Radio Services) internal network selects a specific GGSN among a plurality of GGSNs 125 and serves as an exchanger, 'SGSN' 123, and an external packet network (PDN: Public Data Network). 'GGSN' (124) serving as a gateway of the user, a home location register (HLR) 125 that manages location information for the user's mobile terminal 10 and has an interface with the SGSN 123 and the GGSN 124. Included.

Here, the Node-B 121 and the RNC 122 correspond to a radio access network area. In this radio access network area, the Node-B 121 and the RNC 122 efficiently use limited radio resources to provide high-speed packet data services and provide various QoS of a multimedia system. (Quality of Service) Performs the function that satisfies the requirements.

The SGSN 123 and the GGSN 124 correspond to a packet switched core network, and they provide an IP-based protocol interworking for accessing an existing Internet network to receive a subscriber mobile terminal 10 packet switched service.

In addition, the mobile communication system 12 may provide a service provider's dynamic IP in addition to the AAA server 126 for authentication / authorization / billing of service subscribers and a static IP (Internet Protocol) for packet services to provide additional services. DHCP (Dynamic Host Configuration Protocol) server and the like.

By the operation of the network components (component nodes) as described above, the mobile terminal 10 of the service subscriber can access various Internet servers connected to an external network. The present invention relates to a network for providing a packet service (for example, a GPRS network), and descriptions of other network elements will be omitted.

2 is an explanatory diagram of a call setup method performed by a mobile communication system to provide a data service. When there is a request for a wireless data service from a subscriber, PDP (Packet Data) is performed through GTP tunneling and RAB setup. Protocol) This indicates a process of activating a context, which can provide GPRS, a packet-based wireless communication service.

When the mobile terminal 10 transmits a service request message to the SGSN 123 through the RNC 122 (S200), the SGSN 123 requests a user authentication to the HLR 125 and receives the authentication result. Receives and performs the "Security Mode" which is an authentication process that is transmitted to the mobile terminal 10 through the RNC 122 (S202). If the authentication succeeds by the authentication process, the SGSN 123 transmits a Service Accept message to the service request (S202).

If the mobile terminal 10 transmits an Activate PDP Context Request message to the SGSN 123 through the RNC 122 (S204), the SGSN 123 requests a PDP context setup request (Create PDP Context Request). The message is transmitted to the GGSN 124 (S206).

The GGSN 124 transmits an access request message for subscriber authentication to the AAA server 126 (S208), whereby the AAA server 126 performs subscriber authentication and the authentication result (authentication success or failure). To the GGSN 124 using an Access Accept message (S210).

Then, if authentication is successful, the GGSN 124 performs a predetermined internal processing such as IP allocation, and then transmits a Create PDP Context Response message to the SGSN 123 (PDP Context Response). S212).

Subsequently, when SGSN 123 transmits a radio segment assignment request message to RNC 122 (S214), RNC 122 assigns radio segment to MS 10 (RAB Setup). In step S216, the SGSN 123 transmits a response to the radio section assignment request (RAB Assignment Response) (S218).

Upon receiving this, the SGSN 123 transmits a message (Activate PDP Context Accept) indicating that the PDP context has been set to the MS 10 of the subscriber (S220).

Through the above process, the packet data service is possible between the mobile terminal 10 of the subscriber and the GGSN 124.

3A to 3D are explanatory diagrams of a situation in which data service impossible reasons are applied to the present invention, and FIG. 3A is a case in which a fee is delinquent or a terminal is reported for loss, and FIG. 3B is a case where a balance is insufficient in a prepaid service. FIG. 3C illustrates a case where a connection setting error of a terminal browser occurs when a wireless data blocking service is subscribed. Hereinafter, each reason for the non-data service will be described.

First, referring to FIG. 3A, the case of nonpayment or report of terminal loss will be described.

Due to subscriber reasons such as late payment or lost terminal, the corresponding International Mobile Subsriber Idendity (IMSI) is outgoing data call barring (SGLR) on the Visitor Location Register (VLR) of the SGSN 123. In this case, if the mobile terminal 10 of the subscriber makes an Activation PDP Context Request, the SGSN 123 refuses to activate the PDP context based on 3GPP TS24.008 through the subscriber's HLR. PDP Context Reject) message is transmitted (S300). At this time, the Service Management Fail Cause is an Operator Determined Barring.

Next, a case in which the balance is insufficient or exhausted in the prepaid service will be described with reference to FIG. 3B.

In FIG. 3B, the same procedure as illustrated in FIG. 2 is performed. In the procedure, when the RNC 122 transmits a RB Assignment Response message to the SGSN 123 (S218), The GGSN 124 sets the Acct-status-type of the Accounting Request Message to start and delivers it to the billing system (S310). The charging system that receives the accounting request message recognizes the start of the account and transmits an accounting response message to the GGSN 124 (S312). Accordingly, the packet data service is possible between the mobile terminal 10 and the GGSN 124, and the mobile terminal 10 can transmit and receive data with an application server or a content server providing the requested service (S314).

When the data service is provided through the above process (S314), the billing system checks the balance of the subscriber in real time. As a result of checking the balance, the billing system on the intelligent network makes a disconnect request to the GGSN 124 when the available amount is used up (S316). Then, the GGSN 124 releases call resources for the corresponding subscriber while passing through the SGSN 123 and the RNC 122 (S318).

Alternatively, in some embodiments, the GGSN 124 may perform RADIUS (Remote Access Dial-in User Services) authentication through interworking with the AAA server 126. At this time, if the balance of the prepaid service subscriber is exhausted, the AAA server 126 makes a disconnect request to the GGSN 124.

Next, a case of subscribing to a wireless data blocking service will be described with reference to FIG. 3C.

If the subscriber subscribes to a wireless data blocking service (e.g., a wireless data blocking service for adolescents), if there is a service request from the subscriber's mobile terminal 10, the GGSN 124 accesses the AAA server 126. Make an Access Request.

Then, the AAA server 126 performs RADIUS authentication and transmits an access reject message to the GGSN 124 when the corresponding subscriber is a blocking service subscriber (S320).

Thereafter, when the GGSN 124 transmits a response message (Create PDP Context Response) indicating that the access is denied to the SGSN 123 (S321), the SGSN 123 rejects the activation of the PDP context (Activate PDP Context Reject). To transmit to the mobile terminal 10 (S322).

In short, during the call setup of the subscriber, the SGSN 123 performs RADIUS authentication through interworking with the AAA server 126 managing the subscriber profile. do.

Next, a case in which a connection setting error of the terminal browser occurs will be described with reference to FIG. 3D.

When the call setup is normally made through the process as shown in FIG. 2, the subscriber uploads a TCP / IP service packet through the mobile browser of the terminal 10 in order to use the actual wireless data service (S330).

At this time, if the subscriber uploads abnormal information other than the previously set connection information (service IP, Port / DNS IP, URL, etc.) to the content provider (CP) (S330), the content provider (CP) ) Finds that the reason for the data service is not available.

When the reason for the data service impossible occurs as described above, the subscriber cannot provide the actual wireless data service S331 from the content provider CP.

4 is a configuration diagram of a system for providing a data service unavailable notification service in a mobile communication network according to an embodiment of the present invention.

The data service impossible notification service system 40 according to the present invention checks (confirms) whether a data service impossible reason (cause) exists due to the reason for the subscriber with respect to the mobile terminal 10 requesting the data service, and checks the result data. When the reason for the service unavailable is confirmed, the mobile terminal 10 notifies the relevant reason.

Data service unavailable notification service system 40 performing the above functions, as shown in the figure, comprises a data service management device 41 and a short message service center (SMSC) 42, respectively The components (constituting means) of are described in detail as follows.

The data service management device 41 checks (confirms) whether a data service impossible reason (cause) exists due to the subscriber's reason with respect to the mobile terminal 10 requesting the data service (400), and the data service is impossible as a result of the inspection. If a reason exists, the short message service center (SMSC) is requested to notify the subscriber of the fact (402).

Here, when the data service management device 41 checks (checks) whether there is a data service impossibility (cause) exists in detail, the data service management device 41, as shown in FIG. By monitoring the operation of the network configuration nodes (for example, RNC, SGSN, GGSN, etc.) or the traffic of each network section in real time, it is possible to obtain information on whether there is a reason for no data service and about the subscriber (subscriber who has an impossible reason). do. That is, the data service management apparatus 41 recognizes the reason for no data service by monitoring the operation of the network configuration node or the traffic for each network section performed as shown in FIGS. 3A to 3D (400).

According to the embodiment, the data service management device 41 actively monitors the data service management device 41 when the network configuration node does not check the data service failure reason, and the network configuration node encounters the data service failure reason during the operation of the node. ) Can be notified. That is, the data service management apparatus 41 recognizes whether there is a reason for no data service and corresponding subscriber information through the information notified from the network configuration nodes. In more detail, the SGSN 123 defers charges or loses the terminal (see FIG. 3A), and the GGSN 124 runs out of balance in the prepaid service (see FIG. 3B) or subscribes to the wireless data blocking service (see FIG. 3C). ), The content server CP may be notified of the information on the connection setting error (see FIG. 3D) of the terminal browser, and by receiving the notification, the reason for the data service failure may be determined.

On the other hand, when the short message service center (SMSC) 42 receives the SMS transmission request from the data service management device 41 with the reason for the non-data service and the subscriber information (402), the mobile terminal of the subscriber through the short message ( 10) to notify the reason for the data service unavailable (404). This results in subscribers noticing why the data service is not provided.

In FIG. 4, the data service management apparatus 41 requests the SMS transmission to the short message service center (SMSC) 42. However, according to the embodiment, the network configuration node that detects the reason for the data service failure is directly applied. The short message service center (SMSC) 42 may be requested to send an SMS.

That is, SGSN 123 in case of late payment or loss of terminal (see FIG. 3A), or insufficient balance in prepaid service (see FIG. 3B) or GGSN 124 in case of subscription to wireless data blocking service (see FIG. 3C). In case of a connection setup error of the terminal browser (see FIG. 3D), the content server CP may request an SMS transmission request to the short message service center (SMSC) 42. Here, depending on the embodiment, in the case of late payment or insufficient balance in the prepaid service, the billing system or the AAA server 126 may request an SMS transmission request to the short message service center (SMSC) 42.

In other words, FIG. 4 corresponds to a case where the data service management device 41 is configured as a system separate from the network configuration node or the content server CP forming the mobile communication network. However, according to the exemplary embodiment, each network configuration node and / or content server CP may be configured to perform a function (role) of the data service management device 41. At this time, each network configuration node and / or content server (CP) may be said to correspond to the data service management device 41 in relation to the reason for the data service impossible.

As already described in detail with reference to the data service unavailable notification service method through Figure 4, it will be briefly described below.

When a request for data service is received from the mobile terminal, it is checked (confirmed) whether there is a reason (data service impossible reason) that cannot provide the requested data service due to the subscriber's reason (S500). In this case, the reason for the data service failure includes a late payment of a fee, a terminal loss report, a lack of balance in a prepaid service, a subscription of a wireless data blocking service, a connection setting error of a terminal browser, and the like.

As a result of the check, if there is a reason for no data service (S502), the reason for not providing the corresponding data service is notified to the mobile terminal of the corresponding subscriber by using a text message (S504). On the other hand, if there is no reason for no data service, since the data service is normally provided, no separate notification is necessary.

On the other hand, the method of the present invention as described above can be written in a computer program. And the code and code segments constituting the program can be easily inferred by a computer programmer in the art. In addition, the written program is stored in a computer-readable recording medium (information storage medium), and read and executed by a computer to implement the method of the present invention.
