The limit delay information may include information on a maximum time (time interval) during which the user device may not access the authentication AP as much as possible when transmitting the multimedia contents to the user device through the authentication AP.

In the multimedia contents providing system, the data traffic of the multimedia contents transmitted to the user device through the authentication AP for the unauthenticated multimedia contents service may be limited to less than the critical data traffic.

Hereinafter, for convenience of description, it is assumed that the authentication AP provides the unauthenticated multimedia content service to the first user device 510, the second user device 520, and the third user device 530.

For example, the first user device 510 may be connected to the first user device 510 via the authentication AP based on the limit data traffic information of the first multimedia content included in the header of the first multimedia content data 550, It may be determined whether to transmit the first multimedia content. The first multimedia content may be transmitted to the first user device 510 through the authentication AP only if the threshold data traffic of the first multimedia content transmitted to the first user device 510 is below the threshold data traffic.

Conversely, if the threshold data traffic of the first multimedia content transmitted to the first user device 510 via the authentication AP exceeds the threshold data traffic, transmission of the first multimedia content to the first user device 510 may be limited have.

When the threshold data traffic of the first multimedia content transmitted to the first user equipment 510 through the authentication AP exceeds the threshold data traffic, the authentication AP transmits the threshold data traffic of the first multimedia content to the service management server Quot; is < / RTI > exceeded. Or whether the threshold data traffic of the first multimedia content transmitted to the first user device via the authentication AP exceeds the threshold data traffic may be directly determined to the service management server.

The service management server may request the multimedia content server providing the first multimedia content to set the threshold data traffic of the first multimedia content to less than the threshold data traffic.

The second user device 520 and the third user device 530 can also adjust the limit data traffic of the multimedia contents transmitted to the respective user devices in the same manner.

The user device can access the authentication AP based on contention using a CSMA / CA (carrier sense multiple access with collision avoidance) on the wireless LAN network. If the number of user devices coupled with the authentication AP is greater than or equal to the threshold number, the probability of the user device accessing the authenticating AP to transmit / receive the multimedia content may decrease. Specifically, when there are a large number of user devices coupled with the authentication AP, the user device accesses the authentication AP to receive the first multimedia content data 610, receives the first multimedia content data 610, It may be difficult to access the authentication AP based on the CA to receive the first multimedia content data 610 and the subsequent second multimedia content data 620. In this case, the delivery of the multimedia contents to the user device can not be done smoothly. Accordingly, the authentication AP can limit the number of user devices / user devices that can receive the unauthorized multimedia content service.

For example, the service management server (or the authentication AP) can receive the unauthenticated multimedia content service smoothly considering the capability information of the authentication AP and the limit delay information of each of a plurality of user equipments accessing the authentication AP It is possible to judge whether or not it is a user device.

The waiting time, which is the waiting time for accessing the authentication AP of the user apparatus requesting the unauthenticated multimedia content service, can be determined. The waiting time estimate may be determined in consideration of the number of user equipments coupled with the authenticating AP, the access frequency to the authenticating APs per combined user device, and the time resources required for transmitting / receiving data after access.

In such a case, the waiting time 660 of the third user device may be determined based on the access frequency to the authenticating AP of each of the first user device and the second user device, the data transmission / reception after access of each of the first user device and the second user device, Can be determined in consideration of the time resource allocated for the time.

If the waiting time 660 of the third user equipment is less than the threshold delay 650, it can be determined that the provision of the unauthorized multimedia content service to the third user equipment is possible without delay. Conversely, if the waiting time 660 of the third user equipment is less than the threshold delay 650, it can be determined that the provision of the unauthorized multimedia content service to the third user equipment is performed with a delay.

When the service management server (or the authentication AP) determines that it is impossible to provide the delay-less unaudited multimedia content service to the third user device, the service management server (or the authentication AP) may restrict access for the unauthorized multimedia content service of the third user device.

The service management server may transmit information on the estimated waiting time 660 to the multimedia contents server providing the multimedia contents to the third user device. The multimedia content server may adjust the threshold delay of the third user equipment in consideration of the waiting time 660 of the received third user equipment.

The authenticating AP may send information about the first partitioned time resource 710 and information about the second partitioned time resource 720 to the user equipment associated with the authenticating AP.

A user device that wishes to use the unauthorized multimedia content service of the user device based on the information of the first divided time resource 710 and the information of the second divided time resource 720 may authenticate the first divided time resource 710 A user apparatus that accesses the AP and wants to use another service other than the unauthorized multimedia content service can access the authentication AP from the second divided time resource 720. [

The first partitioned time resource 710 and the second partitioned time resource 720 may be partitioned based on the access purpose of the user devices coupled to the authentication AP. The first divided time resource 710 and the second divided time resource 720 may be determined in consideration of the number of user apparatuses to receive the unauthorized multimedia contents service, the limit data traffic of the user apparatus, the limit delay of the user apparatus, .

The time allocation for the unauthorized multimedia contents service in the above-mentioned authentication AP may be performed by the service management server (or the authentication AP).
