    Abstract: The present disclosure relates to a method and apparatus to control a web loading time in a network. A method of a network controller to control a web loading time of a terminal includes acquiring information regarding at least one terminal currently accessing a base station. The method also includes detecting a transmission control protocol (TCP) session to download a web content of the terminal. The method further includes among a main object and at least one embedded object included in the web content, adjusting a priority for a transmission of the main object. Accordingly, a loading time of a web content is decreased by increasing a transmission priority of a main object constituting the web content in a network congestion situation.

    Abstract: When a Mobile Node (MN) is assigned IP addresses, the number of which is greater than or equal to the preset number of IP addresses that the MN is capable of being assigned with, the MN identifies information on the pre-emption vulnerability of each session associated with an IP address, and releases an IP address which enables a disconnection of a session. When there are multiple IP addresses associated with the pre-emptable sessions, a consideration is given to multiple conditions related to which IP address is to be selected, one IP address is selected, and the relevant IP address is released. When any IP address cannot be released, a new session is associated with an IP address which can give the smallest overhead to the MN and the network among the existing IP addresses, so that an IP address can be efficiently assigned.

    Abstract translation: 当移动节点（MN）被分配IP地址时，其数量大于或等于MN能够被分配的IP地址的预设数量，MN识别关于每个 会话与IP地址相关联，并释放一个使会话断开的IP地址。 当存在与可预占会话相关联的多个IP地址时，会考虑与要选择哪个IP地址相关的多个条件，选择一个IP地址，并释放相关IP地址。 当任何IP地址不能被释放时，新的会话与IP地址相关联，这可以给现有IP地址中的MN和网络带来最小的开销，从而可以有效地分配IP地址。
