Therefore, the definition should be made based on the contents throughout the specification.

1 shows a network configuration to which the present invention is applied.

The mobile stations (MS) 11, 11 'are preferably mobile phones or PDA phones capable of wireless communication with the base station. The mobile station is equipped with a wireless packet data protocol as described, for example, in the EIA / TIA / IS-707 standard, and can also perform voice and data communication simultaneously with the base station (BS) 12, 12 'and provide multimedia data. Should be available for playback. The mobile station preferably performs IP packet communication using Point-to-Point Protocol (PPP).                     

The base stations (BS) 12, 12 'are installed at fixed locations and can simultaneously provide voice and data communication services wirelessly with the mobile stations 11, 11'. The base station (BS) 12, 12 'is connected to the base station controller (BSC) 13, 13' via a dedicated line.

The base station controllers 13 and 13 'control the plurality of base stations 12 and 12' and are responsible for handoff processing and the like of the mobile station. The base station controllers 13 and 13 'are also connected to mobile switching centers (MSCs) 14 and 14' via dedicated lines, and likewise to gateways 17 and 17 'for wireless data services.

The gateway 17 is located between the packet data serving node PDSN and the base station controller BSC to provide an interface function for providing a wireless Internet service.

MSCs 14, 14 'are coupled to a public switched telephone network (PSTN). Optionally, a mobile switching center (MSC) can be connected to a packet data serving node (PDSN). In addition, the mobile switch is configured to communicate with the image providing server through the interface, so that the subscriber's telephone number information can be transferred from the mobile switch to the image providing server. A mobile switching center (MSC) includes a home location register (HLR) 15 and 15 'that stores subscriber information such as the location and service subscription of the mobile station, and a visitor location register (VLR) for managing mobile stations in the jurisdiction ( 16, 16 ') are connected.

A packet data serving node 18 is provided to provide a wireless Internet service. The packet data serving node PDSN and the mobile station MS perform IP packet communication using a point-to-point protocol, and the packet data serving node performs mobile IP management and registration functions.                     

The image providing server 19 stores an image file directly photographed or edited for each subscriber. At this time, the index value is preferably a mobile station telephone number. That is, the image providing server 19 includes a database, in which the image files photographed and edited by each subscriber are stored. Here, the called subscriber may provide the same image file to all calling subscribers, but the called subscriber may provide the image file by dividing the calling subscriber. The image file is at least one. The image file may be a character file such as a still image (JPEG) file and / or a moving image (MPEG) file and / or an avatar. Meanwhile, the image providing server 19 may be connected to an IP network as shown in the figure, but this may be provided in a mobile communication system. In addition, the subscriber may store an image file photographed or edited by the subscriber using a personal computer or a mobile station in a database of the image providing server.

A method of providing called subscriber image data in a network having the above configuration will be described in detail with reference to FIG.

First, the calling subscriber enters the telephone number of the called subscriber using the mobile station MS and presses the SEND key so that the call setup request is sent to the calling mobile switching center via the base station BS and the base station controller BSC. Delivered 201, 202. The procedure according to the call establishment request follows the well-known IS-95 standard.

When the originating mobile exchange receives the call establishment request from the mobile station of the calling party, the calling party exchange transmits the telephone number of the called party included in the call establishment request message to the home location register (HLR) that manages the information of the called party. The mobile station is queried (203 routing information) and service subscription status (203).

The originating mobile exchange receives a response to the query from the home location register (204). The originating mobile exchange may check whether the called subscriber subscribes to the service through the response. Of course, at this time, the originating mobile switcher checks whether the originating subscriber is a subscriber who can receive the service using a home location register that manages the information of the originating subscriber. This is because the calling subscriber must be a subscriber of the SVD service in order to receive the service.

The originating mobile switching center (MSC) is a mobile station and a packet data serving node (PDSN) for connecting the image server and the mobile subscriber station (MS) of the calling subscriber to the base station controller (BSC) when the conditions for providing the service are satisfied. A point-to-point protocol connection is requested between them (205). At the same time, the originating mobile exchange transfers the telephone number information of the originating and destination subscribers to the image providing server (206).

The base station controller (BSC) requests data channel establishment to the base station (BS) for the point-to-point protocol (PPP) establishment between the mobile subscriber station MS and the packet data serving node PDSN at the request of the originating mobile exchange. (207). At the same time, a circuit establishment request between the base station controller and the packet data serving node (PDSN) is requested (209).

The base station (BS) establishes a data channel with the mobile station in two ways (208).

The first method is described as follows. Currently, a Fundamental Channel (FCH) is set up for establishing a voice call between a mobile station and a base station. The basic channel includes a signaling channel as well as a traffic channel. Accordingly, the base station requests the establishment of a supplemental channel (SCH), which is a data burst channel, using the signaling channel of the base channel. Accordingly, a basic channel for voice service and an auxiliary channel for data service are established between the mobile station and the base station.

The second method is as follows. As with the first method, a basic channel is set up for establishing a voice call between a mobile station and a base station. The base station requests the establishment of an auxiliary channel (SCH) for data transmission to the mobile station using a forward dedicated control channel (DCCH). Accordingly, a base channel for voice service and an auxiliary channel for data service are established between the mobile station and the base station.

Through the above process, a circuit for data service is established between the mobile station and the base station controller, and a circuit is established between the base station controller and the packet data serving node PDSN (210, 211). When the circuit setup is completed in this manner, a PPP connection is started between the mobile station and the packet data serving node, and the mobile IP for packet communication is registered (212). When IP registration for the calling party's mobile station is completed, the IP information of the mobile station should be delivered to the image providing server along with the calling party's phone number. As described above, since the image providing server already has the telephone numbers of the calling subscriber and the called subscriber transmitted from the mobile switching center, the image providing server includes the calling subscriber's telephone number and sends the registration IP information query message to the packet data. Forward to serving node (PDSN). In response, the packet data serving node forwards the IP information about the originating subscriber's mobile station to the image providing server.

Through this process, a TCP / IP session connection is established between the mobile station and the image providing server. On the other hand, the image providing server retrieves an image file stored by the called subscriber for each calling subscriber by using the called subscriber's telephone number and the calling subscriber's telephone number delivered from the mobile switching center. Of course, it is preferable that the called subscriber stores the image file for each calling subscriber, but the called subscriber may provide the same image file to all calling subscribers. In this case, the image file is not stored for each calling subscriber, but only an image file for common use is stored. Here, the image file is preferably at least one.

A detailed operation of the image providing server will be described with reference to FIG. 3.

When the image providing server receives the information (preferably the telephone number) about the calling party and the called party from the mobile switching center (301), it sends a query message to the packet data serving node to obtain IP information about the mobile station of the calling party. do. At the same time, the image providing server retrieves the profile of the called subscriber (302). From the search of the profile, it is checked whether the called party stores the image file classified by the calling party or the common image file regardless of the calling party (303).

As a result of the check, if the image file is stored separately for each calling subscriber, the image providing server uses the calling subscriber telephone number transmitted from the mobile switching center to select the first image file corresponding to the calling subscriber telephone number from the storage table of the called subscriber. Extract (304). Then, the extracted image file is transmitted using the IP corresponding to the originating subscriber's telephone number delivered from the packet data serving node as a destination address (306). Accordingly, the image file is transmitted to the mobile station of the calling subscriber.

On the other hand, if the common image file is stored regardless of the originating subscriber, the first image file stored in the called party storage table is extracted (305). In operation 306, the extracted image file is transmitted using an IP corresponding to the originating subscriber's telephone number transmitted from the packet data serving node as a destination address.

Then, the image providing server checks whether the next image file exists (307). As a result of the check, if the next image file exists, the next image file is extracted, and the image file is transmitted using the IP corresponding to the calling party's telephone number as the destination address (308). If the next image file does not exist (307), it waits whether a session release request is received (309). When the session providing request is received, the image providing server releases the session (310).

Meanwhile, for the present invention, the mobile station requires a function of buffering an image file and playing back in real time. That is, the mobile station of the calling subscriber buffers an image file transmitted from an image providing server in a streaming form in a volatile memory (buffer), and when buffering of one image file is completed, displays the image file in real time through the display unit. If the new image file is transmitted during the display of the image file, the mobile station performs buffering as well. Then, when the reproduction for one image file is completed, the mobile station performs reproduction for the next image file.

On the other hand, the originating mobile exchange requests the PPP connection to the base station controller and simultaneously requests call setup to the terminating mobile exchange in the region to which the called party belongs. The voice call processing procedure between the originating mobile exchange and the terminating mobile exchange and the terminating mobile exchange and the terminating subscriber mobile station follows a well-known procedure. In implementing the present invention, the originating mobile exchange may request a PPP connection and at the same time request a call establishment process to the terminating mobile exchange, but preferably after a delay as long as the image file can be transmitted to the mobile station of the originating subscriber, It is a good idea to request call setup processing from the destination mobile switch.

On the other hand, in order to alleviate the inconvenience caused by the delay of the general call setup process in the originating mobile switch, the SVD service subscriber may maintain a dormant state after completing resource allocation for PPP access in advance. That is, the mobile exchange receives the SVD subscription information of the mobile station from the home location register while registering the mobile stations entering its jurisdiction, and allocates resources for data transmission to the SVD subscribers in advance. Stay dormant. In this case, management sessions increase according to the number of SVD subscribers, and a waste of resources occurs, but the setup time for the PPP connection is faster. Accordingly, the outgoing mobile exchange can process the voice call setup without delay.

The call establishment process establishes a call between the calling party mobile station and the called party mobile station by the call setting process (215), and if the interrupt is generated at the calling party's mobile station or the interrupt is generated by the calling party's operation, the mobile station stores the buffered image file. Removes the resource request to the base station controller (216). Accordingly, the base station controller requests release of resources allocated to the packet data serving node (217), and requests release of resources allocated between mobile stations to the base station (218). As a result of this, release of resources for the data service is achieved. The release procedure of the resource follows a known procedure.

On the other hand, when the resource is occupied in advance and kept in the dormant state, the resource release may be performed only by switching to the dormant state.

While the content of the present invention has been described by way of examples, the embodiments of the present invention are merely illustrative of the present invention and should not be construed as limiting the scope of the present invention. Those skilled in the art to which the present invention pertains may modify or alter the present invention in various forms within the principles and scope described in the claims herein.

According to the present invention as described above, after the calling party calls the called party, the mobile station of the calling party can download the image file set by the called party in real time and wait. As a result, it is possible to provide various services to subscribers in the upcoming communication network, and subscribers can effectively promote themselves.
