Abstract: PURPOSE: A method for determining handover between heterogeneous networks using a network state function and a wireless terminal are provided to reduce unnecessary handover by considering the characteristics of the network synthetically. CONSTITUTION: A memory (20) stores application requirement according to the type of a target application. A handover determining part (26) compares the quality of a primary network, which is a network used by the target application currently, with the requirement of the target application according to the type of the target application stored in the memory. The handover determining part determines handover from the primary network to a secondary network, on the basis of the comparison result of the primary network quality and the target application requirement. [Reference numerals] (21) Network quality estimation unit; (23) Application requirement spec estimation unit; (24) Estimate; (25) Setting value; (26) Handover determination unit; (30) H/W and/or S/W resources; (40) First network interface unit; (50) Second network interface unit; (AA) First network; (BB) Second network
Abstract translation: 目的：提供一种确定使用网络状态功能的异构网络和无线终端之间切换的方法，以通过综合考虑网络的特性来减少不必要的切换。 构成：存储器（20）根据目标应用的类型存储应用需求。 切换确定部（26）根据存储在存储器中的目标应用的类型，将目标应用当前使用的网络的主网络的质量与目标应用的需求进行比较。 基于主要网络质量和目标应用需求的比较结果，切换确定部分确定从主网络到辅助网络的切换。 （21）网络质量估计单元; （23）应用需求规格估计单位; （24）估计; （25）设定值; （26）切换判定单元; （30）H / W和/或S / W资源; （40）第一网络接口单元; （50）第二网络接口单元; （AA）第一网络; （BB）第二网络

Abstract: PURPOSE: A mobility and multicast supporting method in a content recognition network structure and system thereof are provided to change a content focused network based on an existed IP(Internet Protocol) network into a gradual content focused network through a content recognition router and a content recognition agent. CONSTITUTION: A first content recognition agent(750) communicates with a first access station(720) and other apparatuses within one or more networks. A portable terminal(710) transmits content request packets including requested content information to a first content recognition agent through the first access station. The first content recognition agent acquires the content through the network connected with other apparatuses. The first content recognition agent transmits the content to the portable terminal.
Abstract translation: 目的：提供内容识别网络结构及其系统中的移动和多播支持方法，以通过内容识别路由器和内容识别将基于存在的IP（因特网协议）网络的内容聚焦网络改变成逐渐内容聚焦的网络 剂。 构成：第一内容识别代理（750）与一个或多个网络内的第一接入站（720）和其他设备进行通信。 便携式终端（710）通过第一接入站向第一内容识别代理发送包括请求的内容信息的内容请求分组。 第一内容识别代理通过与其他装置连接的网络获取内容。 第一内容识别代理将内容发送到便携式终端。

Abstract: PURPOSE: A gradual conversion method for a content focused network and network system thereof are provided to effectively and rapidly transmit packets by using a content focused transmission method. CONSTITUTION: A packet analysis unit acquires content ID(Identity) information and address for a transmission source and destination(S820). In case requested content is stored, a transmission unit rapidly transmits the stored content to the transmission source(S830,S840). In case the requested content is not existed, a content information base management unit updates content information base(S850). When information for the requested content is existed in a content routing table, a control unit transmits a content request to a content focused network(S860,S870).
Abstract translation: 目的：提供一种内容聚焦网络及其网络系统的逐步转换方法，通过使用内容聚焦传输方式有效快速地发送数据包。 构成：分组分析单元获取发送源和目的地的内容ID（身份）信息和地址（S820）。 在存储所请求的内容的情况下，发送单元将存储的内容快速发送到发送源（S830，S840）。 在不存在所请求的内容的情况下，内容信息库管理单元更新内容信息库（S850）。 当在内容路由表中存在所请求内容的信息时，控制单元向内容聚焦网络发送内容请求（S860，S870）。
