Description

Termination contents information display method by using termination control system in WCDMA}

The present invention relates to a method of displaying incoming content information using an incoming call control system. More specifically, the present invention relates to a technology for displaying information of various contents (text, image, video, etc.) designated by a caller to a called party during a voice incoming call using a call control system in a WCDMA mobile communication environment.

Packet data service of IMT-2000, the next generation mobile communication, is largely classified into Mobile Oriented (MO) service and Mobile Terminated (MT) service according to call generation type.

Standardization and research on the early service, most internet services, and the current international standard mobile calling services than mobile terminating service in organizations such as 3GPP (3 ^rd Generation Partnership Project) as expected to move outbound services such as the next generation of mobile communications The focus is on.

However, considering the service characteristics of the next-generation mobile communication that can be provided anytime, anywhere, peer-to-peer such as a push service that transmits stock information or news to the terminal or a file transfer between the terminal and the terminal It is expected that a packet service requiring a mobile destination service such as a service will be a major application service.

In the current asynchronous next-generation mobile communication network, the service caller needs to know the recipient's Internet address in advance in order to provide the mobile recipient service. In order for this to be possible, the recipient must have a static Internet address (Static IP address). That is, according to the standard specification (3G TS 23.060) of the 3GPP so far, the mobile incoming service can be provided only to a user having a fixed Internet address.

In other words, in the current mobile communication data service environment, the incoming data service technology has not defined an incoming process flow in the synchronous network (CDMA20001x, EV-DO) environment, but the call processing flow for the incoming call in the 3GPP WCDMA asynchronous technology. This is made possible by the fact that the flow is reflected in the specification.

However, there are problems in that GGSN, which is in charge of incoming call control in 3GPP asynchronous network, cannot handle dynamic IP address and processing problem when subscriber information is not static IP address.

In the current voice call, the sender specifies the sound source designated by the caller, but in the WCDMA network, the packet can be transmitted simultaneously with the voice, so that the terminal text message or image video can be displayed on the terminal while the ringing ring.

The present invention is to solve the above problems, the present invention is that when the caller using the WCDMA network designates the content, such as text, image, video, etc. to the specific called party so that the content information specified by the caller is displayed on the called terminal when the ringing bell rings. The purpose is to provide a service.

As the technical idea for achieving the above object of the present invention

Requesting a call from the originating terminal to the originating exchange;

Requesting service processing from an originating exchange to an originating HLR;

Requesting service processing from the originating HLR to the TIIS having the information designated by the calling subscriber according to the service information of the HLR profile;

Responding to the calling HLR with the called party number and content ID information currently subscribed with the calling number in the TIIS;

Transmitting, from the TIIS, a called number, a called number, a content ID, and incoming information about actual content to a called party control system (TCS);

Viewing the called number at the calling exchange and performing a WCDMA voice call processing procedure;

Receiving, at the called terminal, the calling number, the called number, and the content ID information from the called exchange, and waiting for the incoming data message to be delivered without giving the waiting signal to the calling terminal;

Receiving the subscriber location information from the HLR through the called number in the TCS receiving the content information from the TIIS, establishing a session if the session is not established, and delivering the content to the subscriber;

When the content arrives, the receiving terminal transmits an waiting signal (Alerting) message to the calling subscriber, and at the same time as the ringing bell and displaying the content information on the display window of the called terminal provides a method for displaying the called content information.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.

1 is a block diagram of an incoming content information display system using the incoming call control system according to the present invention.

As shown in Fig. 1, the originating and receiving terminal (MS _O : 10a) (MS _T : 10b), the exchange (MSC _O : 20a) (MSC _T : 20b), home location register (HLR _{O / T} : 30), additional service server (TIIS: 40), incoming call control system (TCS: 50), SIP (Session Initiation Protocol) server (60), Gateway GPRS Support Node (GGSN) 70, and Serving GPRS Support Node (SGSN) 80).

The home location register (HLR _{O / T} : 30) serves to manage subscriber information, location information, and service information of the calling and terminating terminal (MS _O : 10a) (MS _T : 10b).

The TIIS 40 transmits the calling number, the called number, the content ID, and the actual content to the incoming call control system (TCS) 50.

The incoming call control system (TCS) 50 receives the subscriber location information from the HLR 30 through the called number, establishes a session when the session is not established, and sets up a WAP (Wireless Access Protocol) push or a Session Initiation Protocol (SIP). It serves to deliver content to subscribers.

The GGSN 70 performs a gateway function for connecting the terminating terminal 10b to an external data network, assigns an IP address, and transmits data received from a packet data network to a corresponding SGSN (GPRS Tunneling Protocol) tunnel. It delivers to each terminal through 80).

The SGSN 80 manages various connection information necessary for mobility and data transmission of the called terminal 10b, and cooperates with the home location register 30 to authenticate location registration and network access permission of the data terminal and to the subscriber. Receive service information.

In addition, it selects the GGSN (70) capable of providing the service required by the terminating terminal (10b) to establish a session, and serves to switch the transport packets using GTP.

2 to 4 are respective flowcharts illustrating a process of displaying incoming content information using the incoming call control system according to the present invention.

As shown in FIG. 2, when the originating terminal 10a requests a call to the originating exchange 20a (S100), the originating exchange 20a services the originating HLR 30 according to the routing triggering information. A processing request is made (S101).

At this time, the originating HLR 30 makes a service processing request to the TIIS 40 having the information specified by the calling subscriber according to the service information in the HLR profile (S102).

The TIIS 40 sends a response to the calling HLR 30 with the called party number and content ID information currently subscribed with the calling number (S103). The HLR 30 receives the response and transmits the information to the originating exchange 20a (S104).

At this time, the TIIS 40 transmits the calling number, the called number, the content ID, and the incoming information about the actual content to the incoming call control system (TCS) 50 (S105).

The originating exchange 20a reports the called number and performs the WCDMA voice call processing procedure (S106).

The called terminal 10b receives the calling number, the called number, the content ID information from the called exchange 20b (S107), and waits for the incoming data message to be delivered without giving a waiting signal (Alerting) to the calling terminal 10a.

At this time, the TCS (50) receiving the content information from the TIIS 40 receives the subscriber location information from the HLR 30 through the called number (S108) if the session is not set up and establishes the session (if the session is set up) (S109), and delivers the content to the subscriber using the WAP Push or Session Initiation Protocol (SIP) (S110).

Finally, when the incoming content arrives, the called terminal 10b transmits an waiting message to the calling subscriber and simultaneously displays the content (text, image, video, etc.) information on the display window of the called terminal 10b. Display (S111).

Meanwhile, as a preferred embodiment of the present invention, when the content arrives at the destination terminal 10b through the TCS 50 as shown in FIG. 3 (S201), the destination terminal 10b is alerted for the corresponding content ID. The content is displayed only when Alerting arrives by checking the waiting information (S202). Otherwise, the packet call is released without displaying the content information.

In addition, as shown in FIG. 4, when the voice terminal alerts the incoming terminal 10b via the TCS 50, the content ID is periodically checked to set a timer for a predetermined time, and the timer is If the content ID does not arrive until the end, only the voice call is performed (S301). At this time, if the content arrives late, the packet call is deleted because there is no waiting information for alerting.

As described above, according to the present invention, when a caller using a WCDMA network designates a content, such as a text, an image, a video, to a specific called party, by providing a service for displaying the content information specified by the caller at the called terminal when the ringing tone rings. Differentiated services according to the user can be provided, and user's convenience can be also achieved.
