The invention provides a heuristic CCN network cooperative caching method. The method comprises the following steps: step S1: a network model is two-level CCN topology, the two-level CCN topology is composed of a control node and common nodes, and one control node and multiple common nodes form an SBS; step S2, the popularity of contents are cached; step S3, a local SBS hit rate is maximized; step S4, an entire network hit rate is maximized; step S5, an average profit obtained by a user is maximized; step S6, an algorithm of an optimal decomposition factor; and step S7, cache replacement of the control node. According to the heuristic CCN network cooperative caching method provided by the invention, an SBS cooperative caching mode is imported between the SBS local hit rate and the entirenetwork hit rate, thereby improving the content diversity of the entire network to a certain extent and improving the entire network hit rate; and meanwhile, the cooperative caching is also performedin the SBS to improve the local hit rate and maximize the average profit obtained by the user.

Heuristic CCN network cooperative caching method

Client devices may have internet and other services available simultaneously from a number of different networks such as wide area mobile broadband networks and local area networks such as Wi-Fi and Ethernet. In cases where a client device is receiving internet service from a local area network, the client device may still need to maintain the communication link with a wide area mobile broadband network even when not actively using its services. A method and apparatus are disclosed that enable a client device with mobile broadband connection capability and at least one local area connection capability to power off its mobile broadband modem but still be connected to mobile broadband network through the internet service which the client device may receive from the local area network. Powering off the mobile broadband modem of a client device may help reduce its power consumption.

Method and apparatus for internet based wireless communication for networks

Network nodes and methods therein are provided for cooperation between different wireless communications networks, such as between a 3GPP network and a WLAN. Information related to a buffer status of at least one wireless device is provided by a first network node operating in a first wireless communication network, to a second network node operating in a second wireless communication network. The information may be an indication of a buffer status of a UE which the first network node considers steering to the second wireless network. The second network node may reply with an estimate of a possible throughput for the UE, where the estimate is based on the information related to a buffer status.
