Abstract

An always-on service control system and a method thereof are provided to efficiently use network resources as the side of a mobile communication network determines whether to set a terminal's state for an always-on service to "on" or "off" according to how frequently the user of the terminal uses a data service and delivers a result to the terminal so that the terminal can turn on or off the always-on service. An always-on service control system comprises a terminal(10-1), a PDSN(Packet Data Serving Node)(60), an AAA(Authentication, Authorization, Accounting) server(70), an AMS(Always-on Management System)(80), and a BPS(Bootstrap Provision System)(90). After executing location registration if power is supplied, the terminal attempts a PPP session connection to use an always-on service if the always-on service is in an on state. The PDSN establishes a PPP session connection with the terminal according to a PPP session connection request from the terminal. The AAA server receives a billing start/stop request message whenever the PPP session connection with the terminal is established or released, and extracts AAA billing information from the billing start/stop request message. The AMS manages the number of session connections, based on a session ID contained in the AAA billing information provided from the AAA server. If the number of session connections within a preset period meets a preset number, the AMS sets the terminal's state for the always-on service to "on". If not, the AMS sets the state to "off". Notified that the terminal's state for the always-on service has been changed, the BPS provides the changed information to the terminal through an SMS message. An MSC(Mobile Switching Center)(40-1) which is connected to at least one BSC(30-1) exchanges a call with the BSC.

The PDSN 60, which has been requested to access the PPP session through the process S34, establishes a PPP session between the terminal 10-1 and the PDSN 60 and responds to the PPP session connection request to the terminal 10-1. It is transmitted (S36).

As described above, when a PPP session connection is established between the PDSN 60 and the terminal 10-1, the PDSN 60 transmits a charging start request message including the AAA charging information to the AAA server 70. (S38).

After transmitting the charging start request message to the AAA server 70 through the process S38, the PDSN 60 periodically transmits the charging information to the AAA server 70.

The AAA server 70 having received the charging start request message from the PDSN 60 through the process S38 described above receives AAA charging information (session ID, subscriber information (IMSI, MSISDN), IP address of the terminal, and session) from the charging start request message. Start time information, amount of use data, etc.) is extracted and stored in the memory area (S40), and the AAA charging information extracted from the charging start request message is transferred to the AMS 80 (S42).

On the other hand, when the terminal user is requested to release the PPP session connection, the terminal 10-1 requests the PDSN 60 to release the PPP session connection in response to the request of the terminal user (S44).

The PDSN 60, which has been requested to release the PPP session through the process S44, releases the PPP session between the terminal 10-1 and the PDSN 60, and requests the terminal 10-1 to disconnect the PPP session. The response is transmitted (S46).

As described above, when the PPP session connection is released between the PDSN 60 and the terminal 10-1, the PDSN 60 transmits a charging end request message including the AAA charging information to the AAA server 70 ( S48).

The AAA server 70 receiving the charging end request message from the PDSN 60 through the process S48 described above includes AAA charging information (session ID, subscriber information (IMSI, MSISDN), IP of the terminal) included in the charging end request message. Address, session end time information, usage data amount, etc.), and store the same in the memory area (S50), and transfer the AAA charging information extracted from the charging end request message to the AMS 80 (S52).

AAA billing information (session ID, subscriber information (IMSI, MSISDN), IP address of the terminal, session end time information, usage data extracted from the billing start / end request message from the AAA server 70 through steps S42 and S52 described above) AMS 80 receives the number of session accesses of the terminal 10-1 by pairing the charge start request message and the charge end request message based on the session ID received from the AAA server 70. In operation S54, it is determined whether the number of session connections in the predetermined period satisfies the predetermined number of times (S56).

As a result of the determination in step S56, when the number of session accesses within the preset period does not satisfy the preset number, it is determined whether the use of always-on service of the terminal 10-1 is set to 'on' (S60).

When the use of always-on service of the terminal 10-1 is set to 'on' as a result of the determination of step S60, the use of the always-on service of the terminal 10-1 is changed to 'off' and then changed. If the result is notified to the always-on usage information notification server 90 (S62, S64), and the use of the always-on service of the terminal 10-1 is set to 'off', the always-on of the terminal 10-1 The service usage information is kept as it is (S66).

On the other hand, when the determination result of step S56 indicates that the number of session accesses within a preset period satisfies the preset number, it is determined whether the use of always-on service of the terminal 10-1 is set to 'off' (S68). When the use of always-on service of the terminal 10-1 is set to 'off', after changing the use of always-on service of the terminal 10-1 to 'on', the change result is always on-use information. If the notification server 90 is notified (S70, S72), and the always-on service usage of the terminal 10-1 is set to 'on', the always-on service usage information of the terminal 10-1 is left as it is. Keep it (S74).

Meanwhile, as the always-on service usage information of the terminal 10-1 is changed, always-on received notification of changed always-on service usage information of the terminal 10-1 from the AMS 80 through the above-described process S64 or process S72. The usage information notification server 90 generates an SMS message including the changed always on service usage information of the terminal 10-1 to provide the changed always on service usage information to the terminal 10-1. (S76).

The SMSC 100 receiving the SMS message from the always-on usage information notification server 90 through the process S76 uses the called number included in the SMS message to the HLR 50-1 for the terminal 10-1. The location information request message for requesting location information of the device is transmitted (S78), and the HLR 50-1 transmits the MSC 20-1 in which the terminal 10-1 is registered according to the location information request of the SMSC 100. Including the routing information obtained in conjunction with the location information response message and delivers to the SMSC (100) (S80).

The SMSC 100 receiving the location information response message through the process S80 receives from the always-on usage information notification server 90 through the process S76 based on the routing information included in the received location information response message. One SMS message is transmitted to the terminal 10-1 (S82), and the terminal 10-1 receiving the SMS message turns on / off the use of the always-on service based on the always-on service usage information included in the SMS message. OFF (S84).

When the use of always-on service of the terminal 10-1 is changed from 'on' to 'off' through the above-described process S84, the terminal 10-1, if there is a current data service call, is currently in progress. After the termination, if there is no data service call currently in progress, the PDSN 60 requests a PPP session disconnection after processing the next attempted data service call.

On the other hand, when the use of always-on service of the terminal 10-1 is changed from 'off' to 'on' through the above-described process S84, the terminal 10-1 is currently in progress when a data service call is currently in progress. Even if the data service call is terminated, the session connection with the PDSN 60 is maintained without being released. If there is no current data service call, the PSN session request is immediately requested to the PDSN 60.

Meanwhile, in the WCDMA network, as shown in FIG. 4, the terminal 10-2 performs location registration with the HLR 50-2 as power is applied (S90), and the always-on-use information notification server previously. Referring to the always-on service usage information provided from 90, if the always-on service usage is set to 'on', the PDP context activation request requesting activation of the PDP context to SGSN 110 to use the always-on service. The message is transmitted (S92, S94).

If the use of always-on service is set to 'off' in step S92, the PDP context activation request message for requesting activation of the PDP context is not transmitted to SGSN 110.

SGSN 110 receiving the PDP context activation request message from the terminal 10-2 through the process S94 transmits a PDP context creation request message requesting the creation of a PDP context to the GGSN 120 (S96). The GGSN 120, which has been requested to generate a PDP context from the 110, prepares to connect to the Internet network and then transmits a PDP context creation response message to the SGSN 110 (S98).

The SGSN 110, which has received the PDP context creation response message from the GGSN 120 through the process S98, transmits the PDP context activation response message to the terminal 10-2 to the terminal 10-2 and the SGSN 110. And establish a session between the GGSN 120 (S100).

As described above, when a session between the terminal 10-2 and the SGSN 110 and the GGSN 120 is established and the terminal 10-2 can use the packet service, the GGSN 120 determines the AAA charging information. The charging start request message including a transmits to the AAA server 70 (S102).

On the other hand, when receiving a session connection release request from the terminal user, the terminal 10-2 transmits a PDP context deactivation request message requesting the PDP context deactivation to the SGSN 110 according to the request of the terminal user (S108).

SGSN 110, which has been requested to deactivate PDP from terminal 10-2 through step S108, transmits a PDP context deletion request message requesting deletion of PDP context to GGSN 120 (S110), and SGSN 110. The GGSN 120, which has been requested to delete the PDP context, transmits the PDP context deletion response message to the SGSN 110 after deleting the set PDP context (S112).

The SGSN 110, which has received the PDP context deletion response message from the GGSN 120 through the process S112, transmits the PDP context deactivation response message to the terminal 10-2 (S114).

As described above, when the session connection between the terminal 10-2, the SGSN 110 and the GGSN 120 is released, the GGSN 120 transmits a charging end request message to the AAA server 70 (S116). The AAA server 70 receiving the charge end request message from the GGSN 120 sends the AAA charge information (session ID, subscriber information (IMSI, MSISDN), APN, IP address of the terminal, session end time information) from the charge end request message. The amount of data used, etc.) is extracted and stored in the memory area (S118), and the AAA charging information included in the charge termination request message is transferred to the AMS 80 (S120).

Meanwhile, AAA charging information (session ID, subscriber information (IMSI, MSISDN), APN, IP address of the terminal, session included in the charging start / end request message from the AAA server 70 through processes S106 and S120 described above). The AMS 80, which has received the end time information, etc., pairs the charging start request message and the charging end request message based on the session ID received from the AAA server 70, and the number of session accesses of the terminal 10-2.
