Hereinafter, a system for processing a data rate subscriber in providing an all-on-one service in a WCDMA service network according to an embodiment of the present invention will be described in detail with reference to the drawings.

1 is a diagram illustrating a structure of a WCDMA-based mobile communication network according to an embodiment of the present invention.

1, a mobile communication network according to an exemplary embodiment of the present invention includes a node 110, a radio network controller (RNC) 120, an SGSN 130, a home location register (HLR) 130, A home location register (HLR) 130, and a GGSN 140. The mobile station 100 is primarily connected to the node 110, Can be provided.

Herein, the node 110 and the RNC 120 correspond to a radio access network area, and the SGSN 130 and the GGSN 140 correspond to a packet-switched core network.

In the wireless network area, a function of satisfying various QoS (Quality of Service) requirements is provided in a multimedia system by efficiently using limited radio resources and providing a high-speed packet data service.

The SGSN 130 and the GGSN 140 that belong to the packet-switched core network area provide an IP-based protocol interworking for matching with the existing Internet network so that the subscriber terminal can receive the packet-switched service.

The SGSN 130 is connected to the RNCs 120 to manage the mobility of the subscriber station 100 and the packet session management. The SGSN 130 establishes a PDP context with the GGSN 140, And transmits the protocol data unit. In addition, the SGSN 130 may perform IP routing and may interact with location registration of the subscriber terminal 100.

The SGSN 130 according to the embodiment of the present invention changes the mode of the GPRS-CSI from the preservation mode to the activation mode when the subscriber station 100 subscribed to the all- It operates on the message defined in the TDP. That is, when the subscriber terminal 100 sends a change request message to the PDP context after transmitting a service request and wants to change the bit rate (from the subscriber terminal 100 to the SGSN 130), the SGSN 130 transmits a PDP context change request message Or a PDA context change request message is received or a timeout time is elapsed when a PDP context change request message is received, or after receiving a service request message, the RNC 120 transmits an RAB Acceptance Request message And confirms the message in the TDP of the GPRS-CSI before transmission.

The message in the TDP of the GPRS-CSI according to the embodiment of the present invention includes general messages such as PDP Context Establishment (PDP Context Establishment), Disconnection, PDP Context ChangeOfPosition, etc., and "NoAction" Quot; UsageLimitExceeded ", where "NoAction" is a message set when the limit of the all-on-one service subscriber has not expired, and "UsageLimitExceeded" This message is set when the subscriber's limit has expired.

This message in the TDP can be set according to the data rate of the all-on-one service subscriber set in the subscriber information. In other words, when the subscriber uses up the data rate, "UsageLimitExceeded" is set, "No Action" can be set if a fee exists.

The SGSN 130 managing the TDP message may include a TDP message setting unit 132, a TDP message inquiry unit 134 and a call control unit 136, as shown in FIG.

The TDP message setting unit 132 sets a control message in the TDP based on the subscriber service information provided from the HLR 140 through communication with the HLR 140 in the intelligent network. That is, if the subscriber service information of the subscriber database (not shown) in the HLR 140 indicates that the data charge limit of the specific subscriber has expired, subscriber service information is provided to the TDP message setting unit 132, The unit 132 sets the control message to "UsageLimitExceeded ".

The TDP message inquiry unit 134 inquires the control message in the TDP according to the time determined by the SGSN 130, and then provides the control unit 136 with information on the control message.

The time point at which the TDP message inquiry unit 134 inquires the control message in the TDP can be made when the subscriber terminal 100 requests the call connection or requests the call connection for the first time and then enters the protection mode and changes to the active mode. That is, when the subscriber station 100 transitions from the protection mode to the active mode, the TDP message inquiry unit 134 inquires the control message of the TDP and provides it to the call control unit 136 at the time of resetting the RAB.

When the control message of the TDP is "NoAction", the call control unit 136 provides a service to the subscriber terminal 100 through the general call processing procedure, that is, the PDP context establishment procedure, and the control message of the TDP is "UsageLimitExceeded ) &Quot;, the subscriber terminal 100 disconnects the call in progress and transmits a query message to the SCP when a call is connected at the time of retrying the subscriber terminal 100, and performs call processing so that only a free site connectable after the limit expires can be accessed .

On the other hand, when the subscriber terminal 100 expires the limit of the data fee during the download, the SGSN 130 blocks the call after the download is completed, that is, deletes the call (session) of the subscriber terminal 100.

The HLR 140 stores location information of the subscriber, service information of the subscriber, and the like, and can provide subscriber service information to the SGSN 130. [ Here, the service information of the subscriber includes whether or not the data charge limit for the all-on-one service subscriber has expired.

The GGSN 140 is a gateway for directly connecting with the packet network or the Internet network, and maintains routing information with the SGSN 130 and the external network, and performs tunneling and IP routing functions.

In the session management method according to the all-on-one service in the WCDMA network having the above-described configuration, the point of inquiry of the control message of the TDP and the call process will be described in detail with reference to the drawings.

FIG. 3 is a flowchart illustrating a call control process for an all-on-on-a-service subscriber that has expired while a call in progress according to an embodiment of the present invention.

3, when the subscriber station 100 first requests a call connection, the TDP message inquiry unit 134 inquires a control message of the TDP. When the control message of the TDP is set to "NoAction" The call control unit 136 allocates a call to the subscriber terminal 100 through communication with the subscriber terminal 100 and the GGSN 150. [ That is, the call control unit 136 of the SGSN 130 activates the PDP context through the PDP context establishment procedure with the subscriber terminal 100, and allocates the call to the subscriber terminal 100. When the SGSN 130 receives the subscriber service information (subscriber data) indicating the data limit expiration of the subscriber terminal 100 from the HLR in the state where the call is allocated, the TDP message setting unit (132) updates the TDP information from "NoAction" state to "UsageLimitExceeded".

The subscriber station 100 transmits an Activate PDPContext Request for activating the PDP context to the SGSN 130 through the RNC 120. The GGSN 140 transmits a PDP context request to the subscriber station 100, (Create PDPContext Request) message for creating a session for the subscriber terminal 100, and transmits an Activate PDPContext Response (Create PDPContext Response) message to the subscriber terminal 100 upon receiving a corresponding Create PDPContext Response ). Accordingly, the SGSN 130 can establish a session with the subscriber terminal 100.

On the other hand, after the SGSN 130 receives subscriber service information from the HLR 140 indicating that the subscriber data, that is, the data fee of the all-on-one subscriber, has expired after establishing a session through the PDP context setting procedure, the SGSN 130 ) Updates the TDP control message set to "NoAction " to" UsageLimitedExceeded ".

After the subscriber station 100 is changed from the protection mode to the active mode, the SGSN 130 receives the service request message from the subscriber station 100 at the time of resetting the RAB, And transmits a Service Accept or Security Mode Command Procedure message to the subscriber terminal 100.

The TDP message inquiry unit 134 of the SGSN 130 inquires the control message of the TDP and provides it to the call control unit 136. The call control unit 136 determines whether the control message of the TDP is " UsageLimitExceeded ", it deletes the PDP context set in the subscriber terminal 100 through interworking with the GGSN 140. [ In other words, the call control unit 136 of the SGSN 130 transmits the PDP context deletion request message to the GGSN 140, receives the PDP context deletion response message in response to the PDP context deletion response message, The PDP context deactivation request message is transmitted to the subscriber terminal 100 to switch the PDP context deactivation request message to the inactive mode and the PDP context deactivation response message is received from the subscriber terminal 100, 100). ≪ / RTI >

According to the embodiment of the present invention, the subscriber station 100 receives the service request message at the time of initial RAB reset upon changing from the protection mode to the active mode, transmits a response message to the service request message, As shown in FIG. 4, when the subscriber station 100 changes from the protected mode to the active mode, the GGSN 140 receives the downlink PDU the SGSN 130 having received the downlink PDU provides the paging to the subscriber terminal 100 and receives the service request message for the paging response from the subscriber terminal 100, To the subscriber terminal 100, and inquire the control message of the TDP.

In another embodiment, as shown in FIG. 5, when the subscriber station 100 changed from the protected mode to the active mode wants to change the set PDP, the SGSN 130 can inquire the control message of the TDP. That is, the SGSN 130 can inquire the control message of the TDP after receiving the PDP context change request message (Modify PDPContext Request) from the subscriber terminal 100. The PDP context change request message is for requesting the subscriber terminal 100 to change the bit rate when the QoS of the set call is conversation or steaming and the SGSN 130 requests the change of the bit rate from the subscriber terminal 100 to which the call is connected When the PDP context change request message is received, the TDP control message is checked during the timeout period to determine the subsequent call processing.

FIG. 6 is a flowchart illustrating a call control process when an all-on-one on-subscriber terminal according to an exemplary embodiment of the present invention requests connection of a call with a data fee limit expired.

6, the control message of the TDP for the subscriber terminal 100 whose data charge limit has expired is set to "UsageLimitedExceeded ", and the subscriber terminal 100 transmits a call connection The SGSN 130 recognizes that the subscriber is a subscriber whose data charge limit has expired based on the control message of the TDP.

Accordingly, the SGSN 130 transmits a PDP context activation response message to the subscriber terminal 100 to set up the PDP context, and processes the call so that only the free sites connectable after the limit expires.

On the other hand, if the data charge limit of the subscriber terminal 100 expires while the subscriber terminal 100 downloads the data, the call connection is terminated after the data download is completed. After the call connection is terminated, the subscriber terminal 100 requests the reconnection After the expiration of the limit, only the free site that can be accessed is accessed and the lock is processed.

According to the embodiment of the present invention, by disconnecting a call at a time when a subscriber whose expiration date has expired does not transmit or receive data, a subscriber who has expired may be prevented from complaining due to a call disconnect during data transmission / reception.
