Description

Paging-based IP Push Service Method in IMT 2000 Network

The present invention relates to a paging-based packet push service method in a next-generation mobile communication network, and more particularly, a terminal that does not have a point-to-point protocol (PPP) setup. The present invention relates to a paging-based packet push service method in a next-generation mobile communication network for allowing a terminal to set up PPP to receive a push service by using a paging scheme of the present invention.

In the past, a short message service (SMS) was used to allow a terminal that does not have PPP set up to receive a push service message to the terminal. The example will be described with reference to FIG. 1.

1 is a diagram illustrating a system and a message flow to explain a conventional push service method.

First, a content provider server (CP) 11 pushes a push message to a mobile station (MS) 14 by using a push access protocol (PAP). Send to the Gateway (Push Proxy Gateway: PPG) 12. The CP 11 sends the push message to the PPG 12 together with a user-defined-identifier, for example 'username@sktelecom.comm'. The PPG 12 has mapping information between the user-defined-recognizer and the temporary (IMSI) and possibly the IP address (S101).

When the PPG 12 receives the push message, it checks whether the corresponding MS 14 has a PPP session. If the MS 14 does not yet have a PPP session, the PPG 12 may use a short message to send a Session Initiation Request (SIR) message to a short message service center. Center: SMSC) 13 to send (S102).

The SMSC 13 sends the received SIR short message to the corresponding MS 14 (S103). When the corresponding MS 14 receives the SIR short message, the MS 14 activates a Session Initiation Application (SIA) (S104).

The SIA of the MS 14 creates a push session with the PPG 12 (S105). The PPG 12 transmits a push message to the MS 14 using the created push session (S106), and the MS 14 sends an application defined in a push message header to process the push message. It performs (S107).

However, the conventional push service method using the short message as described above has a disadvantage in that real-time service is not guaranteed, and operators that do not use the SMS infrastructure are pushed to terminals that do not have PPP set up. In order to implement the service, there is a disadvantage in that a new SMS infrastructure must be established.

The present invention was created to solve the above problems, and its purpose is to enable a terminal to set up PPP using a paging method of a communication network rather than SMS, when there is a demand for a push service in real time. Allows the terminal to immediately set up PPP to ensure real-time delivery of push messages, and also allows PPP to set up as soon as the push proxy gateway receives a message from the content provisioning server, even without an SMS infrastructure. The present invention aims to provide a paging-based packet push service method in a next-generation mobile communication network, which enables a terminal not to transmit a push service message by setting up PPP.

Providing a packet to push service along with the mobile terminal's temporary (IMSI) information to the push proxy gateway responsible for transmitting, the Push Proxy Gateway (PPG) and the Contents Provider (CP) The push protocol (PUSH Protocol: TBD) is used for the mobile station, and the content providing server transmits the packet by designating the address of the mobile terminal as an IP address assigned to the mobile terminal by NAI-like id.

As another example of a paging-based packet push service method in a next-generation mobile communication network according to the present invention, a push packet provided from a content providing server is directly transmitted to a corresponding mobile terminal through a mobile communication network. The push service method includes: a first step of requesting an Internet Protocol (IP) address of the mobile terminal from the content providing server to a packet domain name server; Searching for a location of the mobile terminal based on the address request; Requesting the discovered mobile terminal to initiate a point-to-point session over a paging channel; A fourth step of establishing a session between the mobile terminal and a packet switch of the mobile communication network based on the request; And a fifth step of providing, to the content providing server, an internet protocol address of the mobile terminal obtained from the packet exchanger to the packet domain name server as a result of the session establishment. And a sixth step of transmitting a push packet corresponding to the mobile terminal based on the provided internet protocol address.

In the first step, if the domain name server has the IP address, the IP address is provided to the content providing server to exclude the execution of the second to fifth steps, and to perform the sixth step. It is done.

In the second step, the location of the terminal is searched based on temporary (IMSI) information of the mobile terminal provided with the address request message from the content providing server, and the packet domain name server (PDNS) is located in the mobile terminal. Has mapping information between the FQDN, MSISDN, and IP address, and has mapping information between the MSISDN and the home location register.

Hereinafter, a paging-based data packet push service method in an IMT-2000 communication network as a next generation mobile communication network according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a flowchart illustrating a paging-based packet push service method in an IMT-2000 communication network according to an embodiment of the present invention, in which a packet provided from a content providing server is substituted by a push proxy gateway of a mobile communication network. A flowchart of a push service method in a mobile communication network for push service to a corresponding mobile terminal.

First, the content provider server (CP) 21 transmits a packet for push service to the push proxy gateway (PPG) 22 together with the recognition information of the mobile terminal (MS) 26. do. The push proxy gateway 22 receives a push packet from the content provider server (CP) 21. This packet is sent to the PPG 22 responsible for sending the packet to the mobile terminal 26. The push protocol (PUSH Protocol: TBD) is used between the CP 21 and the PPG 22, and the CP 21 designates the address of the corresponding MS 26 by a NAI-like id. To transmit the packet (S201).

Subsequently, the PPG 22 requests the home location register (HLR) 24 to provide location information of the corresponding MS 26. The PPG 22 requests the HLR 24 for information of the corresponding exchange (MSC) 25 to which the MS 26 currently belongs. The PPG 22 has mapping information between NAI-like id and MSISDN (or MDN) for all subscribers (S202).

Subsequently, the HLR 24 provides the PPG 22 with location information of the MSC 25 to which the MS 26 currently belongs.

The PPG 22 requests the MSC 25 to make the MS 26 start a PPP session based on the provided location information (S204).

The base station (BS) (not shown) belonging to the MSC 25 sends a page message to the MS 26 together with necessary service option information (S205), and the MS 26 responds to the page message. In response to the page response message (S206), the BS sends a response order (BS Ack Order) to the MS 26 (S207). As a result, a traffic channel is formed between the BS and the MS 26 (S208).

The MSC 25 informs the PPG 22 that the requested PPP session has been set up in step S204 (S209).

Next, a PPP session is established by negotiating between the MS 26 and the corresponding PDSN 23 (S210), and when the PPP session is formed, the PDSN 23 uses the PPG 22 to obtain the IP address of the MS 26. ) Is notified (S211).

Finally, the PPG 22 terminates the push service by transmitting the packet received in step S201 to the corresponding MS 26 based on the obtained IP address.

The present invention relates to a push service method for directly performing a push service to a corresponding mobile terminal.

First, when the content providing server (CP) 31 attempts to send an end-to-end packet to the MS 36, the CP 31 sends a packet domain name. Send a DNS query message to the server (Packet Domain Name Server: PDNS) 32 (S301).

If the PDNS server 32 has IP address information of the corresponding MS 36, the IP address is provided to the CP 31, in which case the performance of the following steps S302 to S311 is omitted. Or, if the PDNS server 32 does not have the IP address information of the MS 36, the PDNS server 32, to the home location register (HLR) 34, the switch to which the MS 36 belongs ( MSC) 35 requests location information. In the present invention, the PDNS server 32 has mapping information between the FQDN, the MSISDN and the IP address of the MS, and also has the mapping information between the MSISDN and the HLR (S302).

Subsequently, the HLR 34 provides the position information of the requested MSC 35 to the PDNS 32 (S303), and the PDNS server 32 is based on the position information of the MSC 35. The MS 36 requests the MSC 35 to make it possible to start the PPP session (S304).

Subsequently, a base station (BS) (not shown) belonging to the MSC 35 sends a page message to the MS 36 together with necessary service option information (S305), and the MS 36 transmits the page message. In response to the page response message (S306), the BS sends a response order (BS Ack Order) to the MS 36 (S307). As a result, a traffic channel is formed between the BS and the MS 36 (S308).

Next, the MSC 35 notifies the PDNS server 32 that the requested PPP session has been set up in step S304 (S309), and a packet data serving node as a packet switch with the MS 36. Negotiate between the PDSNs 33 to form a PPP session (S310).

Subsequently, when the PPP session is established, the PDSN 33 notifies the PDNS server 32 of the IP address of the MS 36 (S311).

Finally, the PDNS server 32 provides the obtained IP address to the CP 31 in response to the DNS query message in step S301 (S312), and the CP 31 The push packet is directly transmitted to the corresponding MS 36 based on the obtained IP address (S313).

As described in detail above, according to the paging-based packet push service method in the next-generation mobile communication network according to the present invention, a paging technique is used to ensure a push service in real time by allowing a terminal to set up PPP. Operators who do not have an SMS infrastructure, even without the SMS infrastructure, immediately receive a message from the content provisioning server so that terminals without PPP can set up PPP to send push service messages. .
