Give a way.

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 a color multimedia service network according to the present invention.

1, a mobile station (MS) 10, a mobile switching center (MSC) 20, and a home location register based on a customer oriented information system (COIS) 60 A mobile telephone network having a Home Location Register (HLR) 30; A CP network including a gateway server (GW server) 40 and a content provider server (CP server) 50; And a color multimedia service network including a Color Multimedia Service Server (CMS) 70 and a Color Multimedia Service Intelligent Peripheral (CMS IP) 80.

In the present invention, color multimedia means that a still image, a moving picture, and a sound source are provided at the same time, and various characters, characters, and the like are also included.

The GW server 40 is in charge of the interface between the internal network and the external Internet network and is responsible for security (Security) and firewall (Firewall) functions.

The CP server 50 is responsible for interfacing with an external Internet network and WAP, and provides code assignment and down path of color multimedia for each CP, and manages statistics and billing for each CP. do. That is, when registering a new color multimedia, it assigns a color multimedia code for each CP and transmits them to the CMS server 70 and the CMS IP 80 so as to distinguish them.

The COIS 60 serves as a comprehensive information system that manages customer management, billing, billing, payment, etc. as a customer-oriented information system being designed, built, and operated by a mobile communication service provider.

The CMS server 70 manages codes of a subscriber DB and color multimedia for each subscriber. At this time, the code of the color multimedia (Color Multimedia) is assigned by the CP server.

The CMS IP 80 stores and transmits color multimedia.

2 is a flowchart illustrating a process of registering and releasing a color multimedia service according to the present invention.

First, in order to provide a corresponding service, the corresponding service is registered with the HLR 30 and the CMS server 70 through the COIS 60 (S11).

At this time, the website can also subscribe and cancel the service through the COIS (60).

The HLR 30 requested for registration includes O-CSI (for feature code processing), ProvisionedSS (SS-Code = CMS, SS-Status = “P” and “A” bits set), and CMS-RoutingDigits (Routing Digits for The CMS IP) parameter is set and the InsertSubscriberData is transmitted to the MSC 20 (S12).

The MSC 20 stores O-CSI, ProvisionedSS, CMS-RoutingDigits, and transmits an InsertSubscriberData Ack to the HLR 30 (S13).

Here, 0-CSI is required for activation / deactivation of the CMS. (Ex, * 55 + Video Call Key)

The HLR 30 registers the CMS service and returns a result (S14).

The COIS 60 requests the subscriber to the CMS server 70 to create a subscriber (omit the existing subscriber) and register the CMS service (S15), and the CMS server 70 registers the CMS service and returns a result (S16). .

At this time, the color multimedia code is set as a default code. Also, among subscribers whose CMS is registered, subscribers who want to register and change their own default color multimedia or different color multimedia according to time zones, for example, are provided by a mobile communication provider. You can change to the desired color multimedia through the JUNE) service (WAP), the internet network (WEB), or other automatic answering system (ARS).

3 is a flowchart illustrating a call processing process of a color multimedia service according to the present invention. Here, the outgoing MSC (MSC _O ) is 20a, the incoming MSC (MSC _T ) is 20b, and the incoming HLR (HLR _T ) 30b will be described separately.

First, when the caller attempts to make a video call using the mobile terminal 10, the sending MSC 20a transmits SendRoutingInfo (request information request) to the destination HLR 30b (S21).

At this time, the outgoing MSC 20a transmits by indicating that it is a video call in BearerCapability of NetworkSignalInfo when transmitting the SRI to the incoming HLR 30b.

The terminating HLR 30b transmits a ProvideRoamingNumber (routing information request) to the terminating MSC 20b in order to obtain an MSRN (S22).

The terminating MSC 20b allocates an MSRN and returns a ProvideRoamingNumber Ack to the terminating HLR 30b (S23).

The called HLR 30b returns the SendRoutingInfo ack including the MSRN to the originating MSC 20a (S24).

The originating MSC 20a sets up a call to the destination MSC 20b using the MSRN (S25).

At this time, when the originating MSC 20a sets up a call to the incoming MSC 20b, the originating MSC 20a indicates that the call is a video call in the USI (User Service Information) field of the IAM message so that the call can be distinguished from a video call. . In the case where the incoming and outgoing calls are the same MSC 20, video calls can be distinguished by the setup message of originating and incoming calls.

In addition, by analyzing the USI field in the IAM message of the ISUP, the incoming MSC 20b that recognizes that the call is a videophone call is a color multimedia supplementary service field (ProvisionedSS: SS-Code = CMS) received at the location registration step. If SS-Status = Activation) is activated, paging is performed to the called subscriber and a call is set to the CMS IP 80 using CMS Routing Digits (CMS Routing Digits for CMS IP) (S26).

At this time, when the call is set to the CMS IP 80, the CalledPartyNumber parameter of ISUP_IAM is set to "Routing Digits for CMS IP + subscriber's MSISDN".

When the CMS IP 80 receives the ISUP_IAM, the CMS IP 80 returns the ISUP_ACM, and requests the subscriber's color multimedia code from the CMS server 70 (S27).

The CMS server 80 analyzes the called number and time zone received from the CMS IP 70 and returns the color multimedia code set by the subscriber to the CMS IP 70 (S28).

At this time, when the CMS server 80 confirms, if the subscriber is not registered or is not in the registered time zone, the color multimedia set as the default is returned.

The CMS IP 80 transmits the color multimedia corresponding to the color multimedia code received from the CMS server 70 through the set call (S29).

Thereafter, when the called subscriber responds, the called MSC 20b transmits ISUP_REL to the CMS IP 80 to release the CMS IP call, and sends an ISUP_ANM to the calling MSC 20a to process the incoming call (S30).

As described above, according to the present invention, the caller is different from the color multimedia information (including various videos, sound sources, characters, characters, etc.) set by the called party in the video call connection standby state of the wired telephone and the mobile telephone network. Providing it to has the following effects:

First, the present invention can provide a service using only additional network elements, and not only in existing existing synchronous network networks (IS-95 A / B / C, EvDO), but also any type of core network such as WCDMA network (asynchronous network). It is also applicable to (including wired telephone network).

Second, the present invention can express its own personality to the caller by storing and providing Color Multimedia photographed by the called party himself (totally cover various videos, sound sources, characters, characters, etc.).

Third, the present invention can provide an image of various forms (delivering a video including various greetings for each time zone) by providing different color multimedia set by the CMS subscriber for each time zone.

Fourthly, the present invention contributes to the cultural development of related contents by activating the corresponding service (color multimedia service).
