3 is a flowchart illustrating a service registration method for using a multimedia service according to an embodiment of the present invention.

A user of a mobile terminal 20 who wants to use a multimedia service (CMS) accesses the Internet networks 92 and 94 or applies for the multimedia service (CMS) over a telephone.

On the other hand, the user means the called party, and therefore, the calling mobile terminal is provided with the multimedia content set by the called party.

In the application, the user forms a group by dividing callers requesting a call to their mobile terminal 20, such as family, friends, customers, and the like.

On the other hand, the phone book data stored for each group in the user's own mobile terminal 20 may be applied as it is.

And subscriber information is formed by selecting multimedia content suitable for the characteristics of the formed group.

 In applying for the service, the COIS 50 requests the subscriber to register with the HLRs 18 and 28 as a multimedia service user.

The HLRs 18 and 28 are stored in a database that stores subscriber information of the mobile terminal 20. Set the parameters related to the multimedia service and transmit the set data to the MSC (16, 26).

Subsequently, the MSCs 16 and 26 which have received the set data from the HLRs 18 and 28 store it and return a response message according to the set data to the HLRs 18 and 28.

Meanwhile, the parameter related to the multimedia service (CMS) includes a parameter necessary for activating or deactivating the multimedia service (CMS).

Subsequently, the HLRs 18 and 28 receiving the response from the MSCs 16 and 26 register the multimedia service (CMS) and notify the COIS 50 of the result.

If there is no location registration information in the HLRs 18 and 28, related information is not sent to the MSCs 16 and 26.

In this way, a service registration recipient who subscribes to a multimedia service (CMS) provision unit as a member of a multimedia service (CMS) may register in advance multimedia contents for each calling group in the CMS server 62 through the Internet network 92 or 94. The CMS server 62 stores and manages information of the called mobile terminal and a code according to the multimedia content of the calling group.

4 is a flowchart illustrating a call processing of a multimedia service according to an embodiment of the present invention.

That is, when the caller attempts a video call to the called party subscribed to the multimedia service, a flowchart for explaining a method for providing the caller's mobile terminal 10 with the multimedia content set by the called subscriber registered in the multimedia service providing unit 60. to be.

When the caller requests a call connection by dialing the telephone number of the called mobile terminal 20 using the mobile communication terminal 10 capable of video calling, the calling MSC 16 dialed the dialed number to the called HLR 28. Request incoming information (SRI: SendRoutingInfo) including Digits) (S10).

In this case, it is preferable that the call requested by the calling mobile terminal to the called mobile terminal is an image call and transmitted according to the parameter of the called information.

Subsequently, the incoming HLR 28, which has received the incoming information request from the originating MSC 16, retrieves the parameters of the incoming information, and when the mobile terminal of the called subscriber can support the video call, the routing information (the destination information) is sent to the destination MSC 26. ProvideRoamingNumber) (S15).

However, when the caller attempts to make a video call to the mobile terminal 10 capable of making a video call, but the called party's mobile terminal 20 is a mobile terminal that does not support the video call, or the codec between the caller and the called party does not match, and so on. Incoming HLR 28 preferably performs a callback function directly to the originating MSC 16 to inform that the video call cannot be made so that the voice call is performed.

Meanwhile, the called MSC 26, which has received the routing information through the step S15, allocates the routing information (MSRN: Mobile Subscriber Roaming Network) and sends a response message to the called routing information to the called HLR 28. (S20)

The destination HLR 28 then sends a response message according to the destination information SRI requested in step S10 to the originating MSC 16 including the routing information MSRN returned from the destination MSC 26. (S25)

Upon receipt of the routing information MSRN, the originating MSC 16 translates the routing information MSRN and establishes an ISUP call to the corresponding destination MSC 26 (S30).

At this time, the originating MSC 16 displays and transmits the call in the USI (User Service Information) field of the IAM message so that the call can be distinguished from a video call rather than a voice call.

The User Service Information (USI) field in the IAM message performs a function of distinguishing whether a corresponding call is a voice call or an image call.

If the calling party and the called party's mobile terminals 10 and 20 are located at the same MSC location, the video call can be distinguished by a setup message at the originating and receiving party.

Subsequently, the called MSC 26 analyzes the USI field in the IAM message of the ISUP call set to the called MSC 26 in step S30, and recognizes that the call is a video call call, and receives the multimedia service received in the registration step described in FIG. If is activated, the paging is performed to the called mobile terminal, and at the same time, the ISUP call is set to the CMS IP using the CMS routing information.

At this time, the IAM message of the ISUP call is transmitted to the CMS IP 64 including the CMS routing information and the parameters of the called mobile terminal information and the originating mobile terminal information.

At the same time, the CMS IP 64 sends a response message according to the received message to the destination MSC.

When the CMS IP 64 transmits the calling mobile terminal information to the CMS server 62 (S45), the CMS server 62 searches for a calling group including the calling mobile terminal information received from the CMS IP. The multimedia code data allocated thereto is returned to the CMS IP 64 (S50).

That is, the CMS server first selects outgoing groups owned by the called subscriber mobile terminal information, and finally selects one outgoing group including the outgoing mobile terminal information and searches for multimedia code data allocated thereto.

For example, as shown in Fig. 5, the CMS server is provided with a predetermined number of originating groups, such as group 1 and group 2, according to the called subscriber mobile terminal number information, and the corresponding multimedia codes are assigned to the CMS server.

In addition, each calling group includes a predetermined number of calling mobile terminal number information, which is a calling group according to calling mobile terminal number information set by a called subscriber when a multimedia service is applied as described above with reference to FIG. 3.

Therefore, the group name of the group 1, the group 2, etc. may be set at the discretion of the called party such as "friend", "family", "customer", and the like. You can also group into groups.

It may also be the same as the contents of the phone book registration stored in the mobile terminal of the called subscriber.

 That is, when the called party's mobile terminal number is "010-401-XXXX" and the called mobile terminal number is "010-402-XXXX", the calling mobile terminal number is assigned to "Group 1" of the called subscriber mobile terminal number ( Family) ", and the code information " 01 " assigned thereto is returned to the CMS IP 64.

However, if the originating mobile terminal number information received by the CMS server 62 does not belong to any group as a result of the CMS server 62 inquiry, there is no multimedia code data assigned to the CMS. Sends multimedia data set to default) .

In addition, the CMS IP 64 analyzes the multimedia code received from the CMS server 62 on the set ISUP call and provides corresponding multimedia data to the calling mobile terminal.

On the other hand, when the called mobile terminal answers the call, the called MSC makes a call release request to the CMS IP 64 and transmits a message indicating that the called mobile terminal has answered to the calling MSC to make a video call between the calling mobile terminal and the called mobile terminal. To lose.

As a result, the multimedia service provider stops providing the multimedia content to the calling mobile terminal (S60).

As described above, according to the present invention, the called subscriber can set a different multimedia by setting a group for each caller, thereby providing various multimedia services utilizing the personality of the called party according to the characteristics of the caller group.

For example, when the called party is a salesperson, the called party may distinguish between the general caller and the customer caller to form a sender group and set different multimedia accordingly.

Therefore, there is an effect that even one mobile terminal can provide a multimedia service that can promote sales by distinguishing only its customers.

Although a preferred embodiment of the present invention has been described in detail above, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical spirit of the present invention, and such modifications and modifications belong to the appended claims. will be.
