 2A, 2B, 2C, 2D, and 2E are flowcharts of a video call connection service according to an embodiment of the present invention.

Referring to FIG. 2, a user who wants to use a video call connection service should first register to subscribe to the service. The service registration includes three types of subscriber registration process, ICCS server registration process, and terminal registration process. .

Figure 2a shows a subscriber registration process of the service subscription registration process.

Referring to FIG. 2, a process of authenticating subscription status for a subscriber subscribed to the video call connection service (ICCS) is first performed to determine whether to register an ICCS service (S210 and S211).

Next, it is a step of checking whether the image file is registered in the video call connection service server 100 (S212).

At this time, if the image file is registered in the video call connection service server 100, the network management center of the plurality of operators providing video requests the ICCS service feature code registration (S213).

Here, if the image file is not registered in the video call connection service server 100, the service server 100 registers the subscription information and receives the subscriber's image file registration from the web (S214).

Next, the service registration is requested from the network management center to the HLR using a subscription feature code and a terminal identification number (MIN) of the service subscriber, and the HLR processes the service registration (S215).

Next, the subscription feature code is given to the subscriber and the registered feature code is registered in the VLR through a Qualification Directive Operation (S216).

The data transmission and response process for the ICCS service registration flow by the subscriber is shown in detail in FIG. 2D.

Figure 2b shows a process of registration processing in the service server of the service registration process.

When receiving a server registration request for the ICCS service (S220), the video telephony service server 100 determines the subscriber information, service requirements and receives the requested registration file (S221).

The subscriber number and the service registration feature code are transmitted to the network management center of the operator's network using the SNMP protocol and then registered with the HLR (S222).

In addition, when the terminal makes a service registration request to the exchange, the exchange processes the service subscription feature request (FeatureRequest) to the HLR for the feature code registration (S223).

Next, the HLR assigns a service subscription feature code to the subscriber and registers the registered feature code in the VLR through a Qualification Directive Operation (S224).

Figure 2c shows a process of registration processing in the user terminal of the service registration process.

In addition, referring to the ICCS service registration process shown in Figure 2c, when looking at the registration process by the terminal, the terminal subscriber, for example, for the ICCS registration, for example, pressing a specific number ** 993 # 0107778888 #, MSC is a feature code Process FeatureRequest with HLR to register (feature code) (S231).

According to the above process, the registration process is performed in the HLR (S232). At this time, the ICCS Feature code is put into the subscriber and the MIN / PCSSN information is transmitted to the service server 100 (S233).

When the ICCS registration process is performed (S234), the service server processes the point code subscribe system number (PCSSN) information, and the API of the service server and the terminal is linked to the GGSN / SGSN / PDSN in which the corresponding session information is shared by the MIN. A registration setup is processed and the HLR delivers a Registration Response along with the API driving, and links the video telephony service file registration with the terminal (S235).

2E is a data transmission and response process for an ICCS service registration flow by the terminal.

3 is a flow of subscriber authentication processing in a flow of providing a video call connection service according to an embodiment of the present invention.

Referring to Figure 3, the detailed process of the subscriber authentication process flow is as follows.

First, the caller terminal subscribed to the video call connection service requests an outgoing service to the MSC / VLR via a repeater (RNC / BSS) (S310).

Next, a LocationRequest is performed from the MSC / VLR to the HLR (S311).

In addition, the service request is transmitted by transmitting the MIN and the PCSSN from the HLR to the service server (S312).

The service server requests a subscriber service authentication for the MIN from an authentication server (DHCP server) (S313), and transmits the subscriber service authentication response from the authentication server to the service server (S314).

In addition, the service server performs a service session request from the PDSN / GGSN / SGSN (S315), and performs a service session response from the PDSN / GGSN / SGSN to the service server (S316).

Next, push the API driving data from the service server to the caller terminal (S317).

4 is a routing table for routing to a provider network in a service method according to the present invention.

Referring to FIG. 4, the subscriber table is assigned to the key domain by the PCSSN, service category, and file ID with respect to the mobile station identification number MIN.

In the routing table, screen bits are determined for the PCSSN as key domains, and respective IP addresses are designated for the GGSN_id, the SGSN id, the PDSN id, and the SC id.

The processing algorithm according to the routing table finds the service type and file ID from the ICCS service request (MIN / PCSSN) received by the PCSSN and checks the screen bits based on the PCSSN registered in the routing table. It determines whether any of the SGSN id, PDSN id, SC id.

In this case, if the screen bit is mapped to use GGSN id if 00, use SGSN id if 01, use PDSN id if 10, and use SC id if 11, the IP address of SGSN if the screen bit is 01 Routing process.

 5 is a signal transmission and reception processing diagram for automatic recovery processing when a service abnormality occurs according to the present invention.

In the present invention, the ICCS service server 100 sends a Keep Alive Signal to the GGSN / SGSN / PDSN / SC for a predetermined time, for example, 30 seconds, as shown in FIG. 5 to confirm the communication channel. Check the response signal for

If a response signal is received from the ICCS service server 100, there is no problem, but if there is no response, the transmission is retransmitted three times in 10 seconds. If there is no response, the communication channel is reported as having an error. Go through the same process.

First, in the case of a WCDMA network, when no response signal is input from the GGSN, the SGSN is first checked, and if no response signal is input from the SGSN, routing processing is performed to the PDSN.

On the other hand, in the EVDO network, if there is no response signal from the PDSN, the SC is checked first, and if there is no response signal from the SC, the service is determined to be out of service and processed.

In addition, when all communication channels are restored, WGSDMA is managed first by GGSN, and EVSN is managed by PDSN first.

6 is a flowchart illustrating a process of providing a video call connection service in an EVDO network.

The service server 100 receiving the service request from the HLR sends the packet data together with the corresponding MIN number to the corresponding PDSN (S611 and S612).

Upon receiving the PDSN, the PDSN receives the PPP session information from the session control unit based on the corresponding MIN and informs that there is an ICCS service process (S613).

Upon receiving this, the MSC makes a delay of about 15 seconds to the originating BS by setting a timer for processing the alerting information (S614).

Thereafter, in order to process the transmitted data processing packet, an image file is transferred to the corresponding API after performing the PPP connection procedure (S615 and S616).

Since the alerting information is delivered to the BS after 15 seconds (S616), the terminal can return to the traffic channel for voice again and process ringback tone information (S618).

7 is a flowchart of processing a video call connection service according to the present invention in a wired network.

 After the originating subscriber is terminated, the ICCS service request is received by the ICCS server (S711), and the soft switching (SSW) informs the access gateway (AGW) that it is an ICCS call through a Modify Message, and the AGW performs any RING related operation. no action.

In the case of the called subscriber, the SSW notifies the AGW that it is an ICCS call through a Modify message (S713), and the AGW does not perform any RING related operation through this.

Thereafter, the image file information is transmitted through the multimedia gateway (MGW) (S712 and S714), the ICCS Service End is processed by the subscriber's alerting operation, and then the ICCS server stops transmitting the file (S715).

In addition, the video call connection service according to the present invention can be implemented in a WCDMA network.

If the authentication is performed according to the call request from the terminal to the exchange, and the data service request is made to the SGSN after the setup is set, the HLR sets the radio resource to the MSC.

Now, data service activation is performed between SGSN and GGSN, and when data service is accepted from the SGSN to the UE, data is transmitted.

As described above, according to the video call connection service system and method according to the present invention, by displaying the video data as well as the various video messages desired by the subscriber away from the voice or sound source on the originating terminal to the unique self-PR, individual expression between users It can provide a new service for, and contribute to the popularization of multimedia video, DMB service that can be commonly used as data content.
