Implement a receiving configuration.

Therefore, in the present invention, session division is performed in the management apparatus 400 or 401 to implement simultaneous link transmission through a plurality of heterogeneous networks for one session. In this case, since the terminal devices 100 and 101 are connected to each of a plurality of heterogeneous networks (eg, 3G networks and WiFi networks), the management apparatus 400 and 401 may simultaneously link through a plurality of heterogeneous networks (eg, 3G networks and WiFi networks). Recognizing that each is a link of one terminal device (100, 101) and must be managed by one terminal device (100, 101), that is, one subject. To this end, it will be inevitably required to allocate / manage a separate identifier (eg, a temporary signature) for the transmission service in correspondence with the terminal devices 100 and 101.

The external device 500 refers to a server device that transmits and receives data to and from the terminal device 100 through the management devices 400 and 401. For example, the external device 500 transmits and receives data through the management devices 400 and 401 to the terminal devices 100 and 101. Various services such as portal service and content providing service can be provided.

In addition, the policy management apparatus 600 may include, for example, terminal devices 100 and 101 and management devices according to various network parameters and network state variations on heterogeneous networks including subscriber preferences, subscriber types, subscription plans, types of service target applications, and the like.

Meanwhile, the heterogeneous network may correspond to various access networks including, for example, WCDMA, CDMA, WiBro, WLAN (WiFi), and Long Term Evolution (LTE). However, in this embodiment, for convenience of description, a wireless packet service network A description will be given of the first network (hereinafter referred to as "3G network") and the second network (hereinafter referred to as "WiFi network"), which refer to (WCDMA) and the short-range wireless network (WiFi).

Accordingly, the first network device 200, 201 refers to a GGSN (Gateway GPRS Support Node) device for operating a 3G network, that is, a wireless packet service network, and the second network device 300, 301 is a WiFi network, It refers to an access point (AP) for operating a local area wireless network.

In addition, the terminal device (100, 101) and the management device (400, 401) may be a transmission device according to the service flow, that is, the uplink process and the downlink process according to the subject transmitting data using the data simultaneous transmission service. It can also be a receiver. In the present embodiment, for convenience of description, it is assumed that the terminal devices 100 and 101 perform data transmission and reception in a heterogeneous network environment, and the management devices 400 and 401 provide data simultaneous transmission service to the terminal devices 100 and 101. This will be described.

First, in order to use the simultaneous data transmission service in a heterogeneous network environment, a procedure for acquiring connection information between the terminal device 100 and 101 and the management device 400 and 401 must be performed.

In this regard, the terminal apparatuses 100 and 101 perform location registration on the 3G network to obtain their first network access information (eg, 3G IP) from the first network apparatus 200 or 201 according to the existing access information allocation method. The first network apparatus 200 requests the first network apparatus 200 for access information of the management apparatuses 400 and 401 for 3G network access. In addition, the terminal device (100, 101), by accessing the WiFi network will be assigned their second network access information (for example, WiFi IP) from the second network device (300,301) according to the existing access information allocation method. .

Accordingly, the first network apparatus 200 or 201 may request the 3G network access to the management apparatus 400 or 401 from the address assignment apparatus, for example, a DNS server, in response to a request for access information transmitted from the terminal apparatus 100 or 101. Obtain the connection information of the management device (400, 401) for the 3G network connection as IP and transmits it to the terminal (100, 101). Accordingly, the terminal apparatuses 100 and 101 recognize connection information (eg, management apparatus 3G IP) of the management apparatus 400 and 401 for accessing the 3G network, which can access the management apparatus 400 and 401 through the first network, that is, the 3G network.

Furthermore, the terminal apparatuses 100 and 101 further request the first network apparatuses 200 and 201 to access information of the management apparatuses 400 and 401 for WiFi network access.

Accordingly, the first network device 200, 201 is a public address mapped to the connection information for the WiFi network connection to the management device (400, 401), that is, the address allocation device, for example, the management device (400, 401) from the DNS server. (Public) obtains the connection information of the management apparatus (400, 401) for connecting to the WiFi network as IP and transmits it to the terminal (100, 101). Accordingly, the terminal device 100 or 101 recognizes connection information (eg, management device WiFi IP) of the management device 400 or 401 for accessing the WiFi network that can access the management device 400 or 401 through the second network, that is, the WiFi network.

Meanwhile, as described above, the terminal apparatuses 100 and 101 request the first network apparatus 200 and 201 to access information (eg, management apparatus 3G IP) of the management apparatus 400 and 401 for the 3G network access to the management apparatus 400 and 401. Acquiring / recognizing connection information (eg, management device WiFi IP) of the Wi-Fi network access management device 400, 401 is only an embodiment, and the access information of the 3G network connection management device 400, 401 may be obtained from the terminal device 100, 101. Example: Acquiring / recognizing connection information (eg, management device WiFi IP) of the management device 3G IP) and the management device 400, 401 for accessing the WiFi network may be possible through various procedures.

Next, when the above-described access information acquisition procedure for the management device (400, 401) is completed, the service registration procedure between the terminal device (100, 101) and the management device (400, 401) should be performed.

In this regard, the terminal devices 100 and 101 request service registration by accessing the management devices 400 and 401 through respective networks based on the obtained access information for 3G network access and access information for WiFi network access.

For example, the terminal devices 100 and 101 access the management devices 400 and 401 through the first network, that is, the 3G network, based on the obtained connection information (eg, the management device 3G IP) of the management device 400 and 401 for accessing the 3G network. By sending a binding update message (Binding Update) requests the service registration for the terminal (100, 101) itself. The management device (400, 401) is additional information included in the service registration request, for example, device identification information (eg IMSI), the first network access information (eg 3G IP), the network indicating the type of network to send the binding update message this time Check the type information (eg 3G) and service classification information (Initial, Update, Remove) to perform service registration for the terminal device (100, 101) and return a binding update response message (Binding Update Ack) to the terminal device (100, 101). Thus, the service registration procedure through the 3G network can be performed.

In addition, the terminal device (100, 101) is connected to the management device (400, 401) via a second network, that is, WiFi network based on the obtained access information (for example, management device WiFi IP) of the management device (400, 401) binding update message (Binding Update) Request a service registration for the terminal (100, 101) itself. Accordingly, the management apparatus 400 or 401 may indicate additional information included in the service registration request, for example, device identification information (eg IMSI), second network access information (eg WiFi IP), and a network type indicating a network binding update message. Check the type information (for example, WiFi) and service classification information (Initial, Update, Remove) to perform service registration for the terminal device (100, 101) and return the binding update response message (Binding Update Ack) to the terminal device (100, 101). As a result, a service registration procedure through the WiFi network may be performed.

In this case, for the heterogeneous network-based data transmission service according to the present invention, a separate identifier (eg, a signature) must be allocated to the terminal apparatuses 100 and 101, and the management apparatus 400 and 401 can manage the same.

Hereinafter, a heterogeneous network-based data transmission service system according to a first embodiment of the present invention will be described with reference to FIG. 1 by using a terminal apparatus 100, a first network apparatus 200, a second network apparatus 300, and a management apparatus ( Reference is made to 400).

In the service registration procedure of the terminal device 100 to the management device 400 through the 3G network or the WiFi network as described above, the management device 400 generates a temporary signature more specifically than an identifier for the terminal device 100. Can be assigned. For example, the management device 400 may generate a temporary signature based on a unique value based on MDN, IMSI, IMEI, etc. corresponding to the terminal device 100.

Accordingly, the management apparatus 400 may manage table information for each subscriber including registration information including an identifier of a device registered in service for each subscriber, that is, a terminal device.

That is, table information for each subscriber is listed / mapped by subscribers based on additional information included in the service registration request of the terminal device 100 received through the management device 400, the 3G network, and the WiFi network, respectively.
