According to another embodiment of the present invention, the data of the media file is divided into a plurality of segments in a manner of dynamically dividing the size of the media file at a required point in time, as illustrated in FIG. 4, You may. In this case, as exemplified in Fig. 5, the time scale of the segment obtained for the request via the Wi-Fi network, based on the time magnitude (T SEG0 ) of the segment, (T SEG1 ) larger than a predetermined size (51), and transmits a request for transmission through the cellular network to the segmented interval (DS C1 ). In the present embodiment, the communication network is used alternately for each section divided dynamically. That is, in the example of FIG. 5, the subscript of W in the indicator DS indicating the data interval indicates a period in which the subscriber of C is requested to transmit using the Wi-Fi network and the subscript of C is received through the communication network.

Next, a description will be given in detail regarding the combination of multiple networks in a case where the connection point of the presently connected Wi-Fi network belongs to the special access point list and the combination policy is determined to be "inhibit use ".
When the coalescing policy is "use inhibit ", the usage for the connected connection point can be suppressed in various ways. First, in an embodiment according to the present invention, the rate of restricting the use of the connection point is determined as a certain rate, for example 50%, of the service rate measured for the current connection point, or a predefined rate, It is determined to be 500 kbps. The use inhibition rate thus determined may be determined based on the usage suppression information individually set for the special type of connection point currently connected to the
The
However, as illustrated in FIG. 6B, when the use restraint speed is lower than the requested speed of the media, a plurality of communication networks in the connected state are used together to receive the data of the media file. If the measured service speed of the connection point is equal to or higher than the
If the measured service speed of the connection point is lower than the use inhibition speed (63), the
As described in detail with reference to FIG. 6B, when the use suppression rate is lower than the requested rate of the media, although the bandwidth provided by the Wi-Fi network can be further utilized through the current connection point, . For example, in the case where the current service speed of the access point is higher than the requested speed of the media, although the reception of the media data is sufficient by the sole use of only the Wi-Fi network, As a result, the deficient bandwidth is supplemented by using the cellular network.
6C, when the use suppression rate is higher than the request speed of the media and the service speed of the connection point is lower than the request speed, the
In another embodiment according to the present invention, the use of a special type of connection point connected through the specification of the usage ratio of the cellular network and the Wi-Fi network is suppressed. Of course, such use inhibition information may be pre-set in the
The
If the current service rate does not support the speed obtained for use of the Wi-Fi network according to the designated use suppression ratio, the
In an embodiment according to the present invention, instead of arbitrarily using a plurality of communication networks according to a designated use suppression ratio, a plurality of communication networks may be used in combination by applying the use suppression ratio conditionally. For example, when the usage inhibition ratio is "Wi-Fi network: cellular network = rw: rc", when the usage for cellular network is used over a certain size, Wi-Fi network is used according to the ratio of rw: Data reception may be performed. That is, the data reception using the Wi-Fi network may be performed according to the ratio rw: rc = 1: 2 and whenever the data usage over the cellular network becomes 200 kBytes or more. In this example, the
On the other hand, the centenecontaining the request for transmission at the remote place may not be provided as a quality of service (QoS) but may be provided at various qualities. In this case, the response to the request for the content is provided with the media index information which contains a list of the components that are different from each other in terms of quality or bitrate, which can be provided for the content. The same is true when the selected content is live content that is provided in real time. FIG. 7 is an example of media index information showing that various quality components are prepared for the content, which is provided in response to a request for selecting and requesting live content. If the media index information is received for the requested content in a state in which the combination policy is determined to be "inhibit use ", the

According to the above-described embodiments, in one wireless communication terminal, an application having a target terminal address and an application having a target terminal address are executed together, and data is requested to a remote place through the
In an embodiment according to the present invention, it is also possible to selectively perform the network use restriction by the non-target end address as described above. That is, there is no restriction on the use of the network by the non-target end address, but the use of the network is restricted when it falls under a specific use condition. The specific use condition may be a case where the available bandwidth of the
In an embodiment according to the present invention, the number of target end addresses that allow connections may be limited so that the use of the wireless service by each target end address is smooth to the specified suppression information, for example, the suppression rate. For example, the maximum bandwidth tgtmaxBW that the
In an embodiment according to the present invention, when the data rate used by the target end address or the amount of usage for a certain time is lower than the designated lower limit speed or the lower limit, a procedure of disconnecting the target end address may be performed. In this embodiment, the
In an exemplary embodiment of the present invention, the degree of suppression of wireless service used by the target end address is determined by a backhaul network (the backhaul network is a normal backhaul network) in which the
In another embodiment according to the present invention, the suppression rate is not determined in a manner that uniformly applies to the service to be used for all object end addresses, but is applied differently according to the attribute of the service to be used, depending on the load state of the back- You may. FIG. 14B is a table showing an example of a rule for differentially applying restriction information according to attributes of a service provided for a target terminal address according to the backhaul network load state. In this embodiment, not only the suppression information applied to each of the divided backhaul network load states 1400, for example, the suppression rates are different from each other, but also the properties of the service to be used (video, audio, ), The inhibition information may be different. For example, it may be a value different from each other with the relationship between the v_supV 0> a_supV 0> g_supV 0 between the separated from the load state to the lowest state is specified for each service attribute inhibition rate (1401). When the load of the backhaul network is increased and the load state reaches the predetermined limit level (level 3), the suppression rate for each service attribute may not be reduced proportionally and the service of the specific attribute may be blocked at all (1402). For this purpose, the
In the above embodiment, the attribute of the service used by the target end address can be determined from the other end, that is, the IP address or domain name of the remote place, with which the packet is transmitted and received. For example, if the IP address or the domain name of the remote site corresponds to the "YouTube" site, the service to be used is determined as the "video" attribute, and if the IP address or domain name corresponds to the "melon" site, the service is determined as the "audio" attribute. Of course, when it corresponds to a general portal site, it is judged as a "general" property. The attribute of the service used by each target end address can be grasped from the information on network use provided from the wireless communication terminal to the
In one embodiment of the present invention, the control of the use of the Wi-Fi network of the wireless communication terminal may be performed based on information on network use provided from the terminal. To this end, a special function object is executed in a certain wireless communication terminal, and the special function object is used to store information on an app running in the terminal, for example, an app for a designated specialized service and a general service Information about the execution status of the application for the
Embodiments in which the degree of suppression is dynamically adjusted according to the load of the backhaul network or differentiated according to the attributes of the service to be used may be extended and applied according to the principles and concepts of the present invention. In other words, when the load state of the backhaul network exceeds a predetermined standard while accommodating the use of the wireless service of the connected access points without restraining it, the use of the service is suppressed according to the specified criterion, It can be suppressed differently. Of course, operations such as adjusting the suppression degree or adjusting the differential suppression criterion according to the degree of load can be performed in unison with those in the above embodiment.
The various schemes involved in the method of controlling the use of the wireless communication network of the wireless communication terminal according to the usage conditions, which are described in detail in the above-described embodiments, can be appropriately combined and implemented together as long as they are incompatible with each other.
As far as the principle and concept of the present invention are concerned, the present invention is applicable to a wireless communication network in which a certain wireless communication terminal or the like is used with a certain degree of suppression in the use of a wireless service, in each cell of a normal cellular network for mobile communication A Wi-Fi network, which is a high-speed wireless LAN provided with local wireless services, is described as an example of very narrow service areas. However, the principle and concept of the present invention is that the use of data services outside the Wi-Fi network is relatively inexpensive compared to a cellular network, and other types of wireless communication networks in which wireless services are provided only in limited areas or locations If it is, it can be applied to the connection point forming the communication network naturally. Therefore, the scope of the rights according to the claims can not be excluded by reason that the applied wireless communication network differs from the communication network exemplified in this specification by the name or the communication method.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. , Alteration, substitution, addition, or the like.
