DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

1 is a diagram illustrating a multimedia broadcasting type service providing environment according to an embodiment of the present invention.

1, there is shown a logical example of a W-CDMA (Wideband-Code Division Multiple Access) network capable of providing a multimedia broadcast and multicast service (MBMS) The configuration is known.

Meanwhile, 3GPP and 3GPP2 introduced broadcast and multicast services for GSM (Global System for Mobile Communication) / W-CDMA and CDMA2000, respectively. In 3GPP, it is named as Multimedia Broadcast and Multicast Service (MBMS). In 3GPP2, it is named as Broadcast and Multicast Service (BCMCS) and standard work is completed and commercial service is expected to start soon.

The Multimedia Broadcast and Multicast Service (MBMS) and Broadcast and Multicast Service (BCMCS) modifies the existing wireless network and core network, and broadcast multicast service center BM-SC) has been added.

The Multimedia Broadcast and Multicast Service (MBMS) is a service technology for delivering multimedia contents in a broadcast form in a 3GPP-based mobile communication network. In other words, the present invention provides a method for efficiently delivering as few resources as possible in carrying out a service having characteristics of transmitting the same contents to several users at the same time using broadcast and IP multicast technology.

Also, Multimedia Broadcast and Multicast Service (MBMS) is a structural model, not a service itself. That is, it is a service structure that supports a service provider or a content provider so that it can be useful for creating a new type of service. 3GPP has completed the specification for introducing such a service structure for the purpose of providing broadcasting service for multimedia contents by using GSM / W-CDMA system already in service.

Add a new network element called the Broadcast Multicast Service Center (BM-SC) to modify, supplement and add necessary parts for already existing network components and to link the delivery of new types of service control to the delivery of relevant content And implemented a broadcasting service using mobile communication network. The 3GPP2-based mobile communication network also provides broadcasting type services similar to those using the broadcast and multicast service (BCMCS).

Multimedia Broadcast and Multicast Service (MBMS) has a service area to which each service can be applied and is called a broadcast service area (SA) or a multicast service area (SA) for each service type.

A service area SA to which a multimedia broadcast and multicast service (MBMS) is applied includes units 101a, 101b and 101c of a cell area, a unit of a node base station (Node-B) (RNC), a Serving GPRS Support Node (SGSN) area, and a GGSN (Gateway GPRS Support Node) area, and the different service areas (SA) can overlap each other Do.

In the case of a multicast service, each of the service areas 101a, 101b, and 101c may provide different multimedia broadcast and multicast services (MBMS), and a user who is present in the corresponding service area 101a, Only the terminal 100 receives the service. However, in the case of the broadcast service, all the users in the service area can receive the broadcast service. But only if the user terminal has specified that it can receive the broadcast channel.

Hereinafter, with reference to FIG. 1, each component of the multimedia broadcasting type service providing environment in the W-CDMA network will be described in detail.

The W-CDMA network includes a plurality of user equipments (UEs) 100 and a universal mobile telecommunications terrestrial radio access network (UTRAN) 110 for 3G Universal Mobile Telecommunication System (UMTS) (CN) 120, and a broadcast multicast service center (BM-SC) 130, which is a node responsible for multimedia broadcast and multicast service (MBMS) control, and a multimedia broadcast and multicast service (CP / MB source) 140, 141, 142, 143, and 144 for providing multimedia contents to be delivered via an MBMS service. At this time, a plurality of content providers / content source servers (CP / MB sources) 140, 141, 142, 143 and 144 exist in the form of communicable nodes in a public Internet 150 environment.

The UTRAN 110 includes a plurality of Radio Network Controllers (RNCs) 111a and 111b and a plurality of Node Bs B managed by the plurality of RNCs 111a and 111b 112a and 112b. The Node Bs 112a and 112b receive the uplink signals transmitted from the wireless terminal 100 at the physical layer level and transmit the downlink signals to the wireless terminal 100. [ In other words, the Node Bs 112a and 112b serve as access points for connecting the wireless terminal 100 to the UTRAN 110 by transmitting and receiving signals with the wireless terminal 100 .

In addition, the Node Bs 112a and 112b manage wireless resources on a cell-by-cell basis, thereby configuring and communicating with wireless terminals 100 existing in the corresponding cell. The RNCs 111a and 111b are responsible for allocating and managing radio resources and serving as access points for connecting the Node Bs 112a and 112b to the CN 120. [

The CN 120 comprises one or more SGSNs (Serving GPRS) Support Node (SGSN) 121 and one or more Gateway GPRS Support Node (GGSN) The RNCs 111a and 111b are connected to the SGSN 121 of the CN 120. [ The SGSN 121 is connected to the GGSN 122 to manage the mobility of the wireless terminal and to selectively transmit data for multimedia broadcast and multicast service (MBMS) related services to a specific RNC.

The GGSN 122 functions as a gateway for interworking with the Internet or an external packet network. That is, the GGSN 122 serves as a connection point between the W-CDMA system under the GGSN and the external Internet 150.

A broadcast multicast service center (BM-SC) 130 serving as a broadcast multicast service control node is a functional element of a W-CDMA system for providing a multimedia broadcast and multicast service (MBMS) (MBMS) user service, which is a subject of management and control of multimedia broadcast and multicast service (MBMS), must be present for broadcast and multicast service (MBMS) Provisioning and delivery of service information.

Accordingly, the broadcast multicast service center (BM-SC) 130 manages multimedia broadcast and multicast service (MBMS) subscriber and service information management, multimedia broadcast and multicast service (MBMS) Service authorization, service initiation, multimedia broadcast, and multicast service (MBMS) information transmission. The multimedia broadcast and multicast service (MBMS) uses a packet transmission network of a W-CDMA network to provide a multimedia broadcast and multicast service (MBMS) to the wireless terminal 100, do.

In this case, the interface between the broadcast multicast service center (BM-SC) 130 and the GGSN 122 uses the IP interface used when the GGSN 122 is connected to the external Internet. The broadcast multicast service center (BM-SC) 130 includes a content provider / content source server 140, 141, 142, 143, and 143 for delivering multimedia broadcast and multicast service (MBMS) 144 as an entry point, and can act as a content provider (CP) itself. In this case, the content provider (CP) means a node including an application function for content delivery, and a multicast broadcast source (MB Source) is a node such as a storage server or an FTP server that stores only content, Is transmitted to the wireless terminal 100 through a service application provided by a center (BM-SC) 130 or another content provider (CP).

Under this circumstance, after the wireless terminals 100 register a request to receive the corresponding service, the broadcast multicast service center (BM-SC) 130 transmits the MBMS service request message according to the start time of the specific multimedia broadcast and multicast service (MBMS) When the service content delivery starts, it receives it. These contents are transmitted to a wireless terminal (not shown) through a common channel used in a corresponding service area via the GGSN 122, the SGSN 121, the RNCs 111a and 111b, and the Node Bs 112a and 112b 100).

At this time, the broadcast multicast service center (BM-SC) 130 delivers the content to all the GGSNs 122 supporting the mobile terminal 100 that desires to receive the service, and the GGSN 122 transmits (RNC) 111a and 111b, and the RNCs 111a and 111b transmit the RNCs 111a and 111b to a plurality of SGSNs 122 supporting the RNCs 100. The SGSNs 122 transmit the RNCs 111a and 111b to the RNCs 111a and 111b, (Node Bs) 112a and 112b to the plurality of base stations (Node Bs) 112a and 112b. Finally, the Node Bs 112a and 112b transmit the signals to the wireless terminal 100 through a common channel used in the corresponding service area.

Referring to FIGS. 2 to 5, a method for supporting a personal broadcasting service based on a mobile communication system capable of providing the multicast / broadcast service of FIG. 1, Described in detail is how to perform a content provider role.

2 is a reference diagram for explaining a method of providing a personal broadcasting type service according to an embodiment of the present invention.

The wireless terminals 201a, 201b, and 201c that desire to transmit multimedia contents are not only a first interface that can connect to a cellular mobile communication system capable of providing a multicast / broadcast service as a terminal having a plurality of wireless interfaces, A second interface or a third interface such as a WiBro, a WiMAX, or the like, so that one service can communicate through one interface at any moment.

And these interfaces can be driven by the user's choice. Therefore, the wireless terminals 201a, 201b, and 201c for transmitting multimedia contents provide a procedure for users to select the interfaces held by the wireless terminals 201a, 201b, and 201c when users want to perform a specific service, If the interface is selected, the corresponding module is activated to provide the service through the selected interface.

When the transmitting wireless terminals 201a, 201b and 201c select the first interface 231, which is a cellular mobile communication system for providing a multicast / broadcast service for a personal broadcasting type service, 201b, and 201c by uploading multimedia contents to be provided by the mobile terminals 201a, 201b, and 201c by driving a predetermined procedure by communication with the service providing server 230. [ Here, the personal broadcasting type service providing server 230 may be, for example, a broadcast multicast service center (BM-SC) 130 of FIG.

In addition, if the wireless terminal selects the second interface 221 or 241, the content upload is performed using the corresponding interface. In this case, the device receiving the content to be broadcast may receive the personal broadcast type content and provide a multicast / 201b and 201c to the personal broadcasting service control server 230 of the cellular mobile communication network having the capability of being able to serve as a service agent between the wireless terminals 201a, A content provider node 220 that simply mediates the multimedia contents received from the transmitting wireless terminals 201a, 201b, and 201c and transmits the received multimedia contents to the personal broadcasting type service node or the application function of the personal broadcasting type service Or a service provider node 240 that includes a service provider.

The content provider node 220 or the service provider node 240, which is a network node responsible for delivering content between the wireless terminals 201a, 201b, 201c and the personal broadcasting type service providing server 230, (201a, 201b, 201c) through the mobile terminal (230) and designated procedures (221, 231) and assists the service control.

The multimedia contents transmitted by the transmitting wireless terminals 201a, 201b, and 201c are grouped into the receiving wireless terminals 202 and 203 through the multicast / broadcast service function provided by the cellular mobile communication system shown in FIG. 1 The wireless terminal may be a wireless terminal 202 having multiple interfaces such as a transmitting wireless terminal 201a, 201b or 201c or may be a single interface wireless terminal 203 having only a cellular system interface which is a content transmitting network have. The receiving wireless terminals 202 and 203 receive a service announcement information transmitted from the personal broadcasting service providing server 230 and can perform a multicast / broadcast service function for allowing a user to register a service receiving intention Respectively.

2, a cellular mobile communication network has been described as an example of a delivery network for providing a personal broadcast type service. However, when providing a service server that provides a broadcast type service in another wireless interface network, Interface.

3 is a service provision flowchart in the wireless terminals 201a, 201b, and 201c for transmitting according to an embodiment of the present invention.

When the user requests the execution of the service to use the personal broadcasting type service (S301), the basic information on the corresponding service is first inputted and the service is registered in the system (S310). At this time, the service registration procedure is performed in advance regardless of the service start time, and is used to notify the receiving wireless terminals of what contents personal broadcasting will be present. Each user enters information necessary for the service, such as the time and duration for providing the service to register the desired broadcast service, the service name, the quality level of the content to be broadcasted (S311) The interface to be uploaded is selected (S312).

If the interface selected by the user is the second interface, the designated interface is driven and the service information input by the user is transmitted to the content provider or the service provider through the interface (S330). The selection of such an interface can be selected by reflecting the usage cost of the wireless communication network connected through each interface, the data transmission speed, and the mobility characteristics of the terminal, and the terminal can provide the necessary information for the selection of the user.

Upon receiving a result of the service registration from the service provider (S331), it is determined whether the result of the service registration is successful and whether there is an adjustment request for the service quality (S332). If there is no adjustment request, (S338) and ends the personal broadcasting type service registration procedure.

However, if it is determined that the system processing capacity will be insufficient due to registration of the corresponding service from the cellular mobile communication system capable of providing the multicast / broadcast service, a response to lower the quality of the multimedia content requested by the user is received. (S333), receives the user's selection (S334), and transmits it to the content provider or the service provider who requested the service registration (S335). Then, the service registration procedure result is received (S336), the user is notified (S337), and the registration procedure is completed.

On the other hand, if it is determined in step S312 that the interface selected by the user in the service registration request is a cellular mobile communication system, which is the first interface, the service information input by the user is transmitted to the personal broadcasting type service providing server (S313) And receives the registration result from the providing server (S314). At this time, whether or not there is an adjustment request for the service quality is determined (S315). If the result is successful and there is no service quality adjustment request, the user is informed that the service registration is completed (S320) do.

However, if it is determined that the system processing capacity will be insufficient due to registration of the corresponding service from the cellular mobile communication system capable of providing the multicast / broadcast service, a response to lower the quality of the multimedia content requested by the user is received. (S316), receives the user's selection (S317), and transmits it to the service providing server (S318). Then, the service registration procedure result is received (S319), the user is notified (S337), and the registration procedure is completed.

In step S350, the terminal determines whether the service request received from the user is a real-time delivery of the content to the registered service. If the service request is real-time delivery, the terminal starts operations for producing the corresponding content in step S351. It is further determined whether the selected upload interface is the second interface or the third interface (S352).

As a result, if it is determined that the second interface is the third interface, it is informed that the content provider or the service provider connected to the interface intends to transmit content for starting the service (S360). In step S361, the terminal informs the user that the corresponding content is to be uploaded in step S362, and starts the content transmission in step S363. This content transmission is performed until the service end (S364) is notified by the user. When the service end is inputted, the personal broadcast type service termination procedure is performed with the content provider or the service provider and the process is terminated (S365).

On the other hand, if it is determined in step S352 that the upload interface selected by the user selects the cellular mobile communication network as the first interface, the terminal informs the personal broadcasting service providing server that content transmission is started (S353) (S354), and notifies the user that the content is to be uploaded (S355), and starts the content transmission (S356). This content transmission is performed until the service end (S357) is notified by the user, and if the service end is inputted, the personal broadcast type service termination procedure is performed with the content provider or the service provider and ends (S358).

4 is a service provision flowchart in a content provider or service provider according to an embodiment of the present invention.

That is, it is a service provision flowchart in a content provider or a service provider to receive service information and content from a wireless terminal when the transmitting wireless terminal 201a, 201b, 201c selects the second interface as an upload interface.

Upon receipt of the personal broadcasting type service request from the transmitting wireless terminals 201a, 201b, 201c (S401), it is determined whether the request is service registration or content transmission (S410). As a result of the determination, if the service registration is performed, information on the personal broadcasting type service is received from the terminal (411), registration information is generated according to the protocol for registering the service with the server providing the personal broadcasting type service (S412) The server is requested to register the personal broadcasting type service (S413). When a response to the service registration request is received from the server (S414), the terminal performs a negotiation procedure for service registration (4S20).

(S421). If the result of the response from the server indicates that the service registration is permitted, the normal registration for the service is internally stored (S427) so as to utilize it when there is a content delivery request in the future, And transmits the result to the terminal that requested the service registration (S428).

However, since lack of system resources or degradation of quality is expected at the time when the service is started from the server, if the adjustment information is returned so as to lower the quality of the corresponding content, it is transmitted to the corresponding terminal (S422). If the response selected by the user to the coordination request transmitted to the terminal is returned (S423), it is transmitted to the server (S424). If the user's response agrees with the content quality adjustment in the server, the result of the service registration processing is received from the server (S426). If the result is successful, information for managing the service is stored internally (S427) The final result is transmitted to the terminal (S428). However, if the terminal user does not accept the proposed quality adjustment from the server and rejects it, the content provider or the service provider invalidates the service registration and ends the procedure.

If the request received from the transmitting wireless terminals 201a, 201b and 201c is the transmission of the contents (S430), the service server notifies the start of the personal broadcasting type service (S431) and the transmitting wireless terminals 201a, 201b and 201c (S432). ≪ / RTI > And starts to transmit the received content to the service server (S433) and continues the content transmission until the service end is received from the terminal (S434). In this process, information is gathered internally for storing the information necessary for service control, and information for billing such as traffic volume. When the service termination is requested from the terminal, the service server notifies the service server thereof (S435), performs a procedure for terminating the service with the service server and the terminal, and terminates the service (S436).

5 is a flowchart illustrating an operation of a personal broadcasting type service providing server according to an exemplary embodiment of the present invention.

In the case of the 3GPP cellular mobile communication system, the service providing server may be included in the broadcast multicast service center (BM-SC) 130, and may be included when operating a separate service providing server. In addition, when a wireless communication system other than the 3GPP cellular mobile communication system provides the multicast / broadcast service capability, the service providing server of the present invention can be included in the service providing server of the corresponding system.

When the service providing server receives the service registration request for the personal broadcasting type service from the terminal, the content provider or the service provider (S510), the amount of downlink traffic is predicted at the start of the service and information about the radio resource allocation is collected ). Then, it is determined whether the system idle resource is expected to be insufficient by using such information (S512).

At this time, the service providing server exchanges necessary information with various nodes (for example, GGSN, SGSN, RNC, Node B, etc.) participating in the system internally in order to provide multicast / broadcast service, It is determined whether or not the service registration is permitted. As a result of the determination, if the idle resource of the system is sufficient, the service registration permission is returned to the node (the transmitting terminal, the content provider, or the service provider) requesting the service registration (S520), and various procedures for internally executing the personal broadcasting type service are performed .

However, if it is determined that the idle resource of the system is insufficient and the quality of the service requested by the registered request is required to be lowered as a result of the determination in step S512, the service quality adjustment information is transmitted (S513) and negotiation for service registration is entered . As a result of receiving the intention of the terminal for the service quality adjustment proposed by the server (S514), it is determined whether the service registration should be canceled because the user does not agree to the negotiation (S515). If the cancellation is requested, the service registration procedure is terminated .

If the negotiation condition is accepted from the terminal, a profile for the personal broadcasting type service is created to register the service (S516), and a service announcement procedure for the receiving terminal is performed using the profile (S517). This notification procedure is carried out by broadcasting or multicasting information about the service requested by the transmitting terminal to a specific area, and the receiving terminals receive the information to inform the user of when the corresponding personal broadcasting service is to be provided Informs whether the user has been received, and transmits the received information to the server (S518).

This procedure can be performed independently regardless of when the service is started, and it can be performed at any time before the service starts and after the service is in progress. The server receiving the intention to receive the service from the receiving terminal manages the information of the terminals in the multicast group of the corresponding service.

When the server determines that the start time of the personal broadcast type service previously registered by the service scheduler is coming (S519), the server informs that the corresponding service is to be started in the previously registered receiving terminal group for receiving the service (S521) Does not need to remember the point at the start of the service and wait for it to be seen. That is, the system notifies the user of the service receiving user's convenience. Upon receiving the notification, the receiving user performs an operation for viewing the multimedia contents service at his / her terminal for receiving the service.

When the server notifies the user of the start of the service, the multicast / broadcast session start procedure for transmitting the multimedia contents of the service is performed (S522) The multimedia content transmission is started (S523).

When the end request of the corresponding service is received from the transmitting terminal (S524), the transmission of the content is stopped and the session of the corresponding service is terminated and the service is terminated (S525)

On the other hand, the personal broadcasting type service providing server does not start the service depending on the arrival time requested by the transmitting user but starts the service based on the service starting time requested by the user at the time of registering the service, The content transmission start notification from S550 does not coincide with the service start.

A terminal that transmits a broadcast-type service makes a content delivery request at a time point when a time for registering the service is imminent. In a state where contents are transmitted from a transmitting terminal, The content is transferred. That is, when the personal broadcasting type service providing server receives the content delivery request, it performs authentication and service semantic check on whether the transmission is for the already registered service, user information, etc. (S551) Once the content is received (S552), the content is delivered to the receiving terminal group from that time when the service is started (S519 to S525).

Therefore, if the transmitting terminal starts content transmission too soon before the service start time, a policy such as returning a warning or receiving and discarding the content may be used and a separate policy may be applied to the charging (S553) And a method known to the terminal subscribers may be applied.

According to an embodiment of the present invention, for example, when a user wishes to transmit a game scene played by his or her family or friend to a family member or a friend in Korea at a real-time live game in a swimming stadium held in the United States, A person who has a wedding in a foreign country can do the same service as sending the marriage live to his relatives in his / her home country in real time.

6 is a configuration diagram of a wireless terminal providing a broadcast type service in cooperation with a wireless communication system according to an embodiment of the present invention.

A wireless terminal according to an embodiment of the present invention includes a plurality of wireless interface units 610, a content generation unit 620, a transmission management unit 630, a control unit 640, an audio video processing unit 650, and a memory 660 .

As described above, the wireless interface unit 610 may be configured not only to have a first interface that can be connected to a cellular mobile communication system capable of providing a multicast / broadcast service, but also to a second interface or a second interface such as a wireless LAN, a WiBro, 3 interface so that one service can communicate through one interface at any moment.

The content generation unit 620 generates multimedia contents to be provided to other wireless terminals. For example, the multimedia contents stored in the memory 660 of the wireless terminal are read and transmitted as it is according to a control signal of the transmission management unit 630, or an audio video processing unit 650 having a camera, a microphone, So that multimedia contents can be generated. That is, the transmission management unit 630 controls the multimedia contents to be transmitted through the wireless interface selected by the user among the plurality of wireless interfaces. Meanwhile, the memory 660 stores pre-manufactured multimedia contents.

The controller 640 manages the idle resource and status information of each of the wireless interface units, manages information required for the broadcast type service, and controls service registration to the wireless communication system. That is, it controls the multimedia contents to be transmitted according to the characteristics of the broadcasting service defined by the user in cooperation with the external wireless communication system.
