Embodiment approach

[0051] Such as figure 1 , figure 2 and image 3 As shown, the system for network change in a heterogeneous network according to the present invention includes: terminal devices 100, 300 and 600, which access one of two or more networks 10 (for example, a WCDMA network) , and use the data service through the network; and the policy providing apparatuses 200, 400, and 700, which identify the service-related information of the terminal devices 100, 300, and 600 according to the data service, and generate information corresponding to the identified service-related information. A network change policy of a network change of a specific network (eg, a WLAN network), and the generated network change policy is provided to the terminal devices 100 , 300 , and 600 .

[0052] The terminal devices 100, 300, and 600 correspond to terminals supporting communication for two or more networks 10 including various networks.

[0053] Two or more networks or a heterogeneous network 10 means al...

no. 1 approach

[0129] According to the first embodiment of the present invention, the service-related information includes load status information of a wireless access node corresponding to a network that the terminal device 100 is accessing.

[0130] The device control unit 240 monitors the load state of the wireless access nodes of the respective networks included in the two or more networks 10, and determines whether there is a wireless access node having a load state corresponding to a pre-established change standard. As a result of the determination, when the load state of a specific wireless access node corresponds to the pre-established change standard, the device control unit 240 generates a network change policy corresponding to the load state of the specific wireless access node, and transfers the wireless The change policy is provided to terminal devices 100 connected to said specific radio access node.

[0131] Specifically, the device control unit 240 acquires load status inform...

Abstract

The present invention relates to a policy providing device and a terminal device for supporting a method of changing a connection between heterogeneous networks. Devices and terminal devices are provided for the strategy according to the invention, which connect to one or more networks to use data services. The policy providing device provides the terminal device with a network change policy that identifies service status information on the terminal device according to the data service and obtains a connection change to a specific network corresponding to the identified service status information. The terminal device determines whether it can access the specific network to be accessed by the terminal device based on the received network change policy, and tries to access the specific network, so as to change the network access of the terminal device if it can be accessed. network.

Description

technical field [0001] The present invention relates to a policy providing device and a terminal device supporting network changes in a heterogeneous network environment, and more particularly, to a system and method for performing network changes in a heterogeneous network, a terminal device and its operating method, and a policy providing device And the operating method thereof, wherein the network operator can change the network accessed by the terminal device in a heterogeneous network environment, so that the network operator plays a leading role in effectively distributing data flow to ensure network stability. Background technique [0002] Recently, it is common that communication service providers provide various services based on various wireless communication technologies. Service providers have provided services based on WLAN (eg, WiFi) related short-range wireless networks as well as WCDMA, CDMA and WiBro. In addition, service providers are determined to adopt L...
