摘要： A wireless communication device includes a plurality of different wireless interfaces to facilitate communications with a remote device over a corresponding plurality of networks. The device can switch between the different interfaces to migrate an on-going communications session from one that requires the infrastructure of a fixed wireless communication network to one that does not require the infrastructure of a fixed wireless communication network. Switching between the various interfaces allows the migration to occur while protecting the device against malicious third-party impersonation attacks.

摘要： A system, method, and node for protecting a telecommunication system against a mobile and multi-homed attacker, MMA (10). The telecommunication system includes one or more correspondent nodes, CN, (102, 104) for transferring data packets. A mobile and multi-homed network node, MMN, (108) associated with the MMA communicates and receives data packets with the CN. An access router, AR, (106) transferring data between the MMN and the CN performs a reachability test with the MMN to determine if the MMN is still reachable. The AR sends a message to the CN to flush cached information associated with the MMN if the MMN is not reachable by the AR. The CN, upon receiving the message to flush cached information, flushes binding cache entries associated with the MMN from the CN.

摘要： A wireless LAN comprises an access point with a data communicator for data communicated over different channels, each using a respective wireless technology, and at least one mobile communications device with a data communicator for data communicated over the channels and using the wireless technologies. A first of the channels uses a wireless technology operating at a first frequency bandwidth, and a second of the channels uses a different wireless technology operating at a second, non-overlapping frequency bandwidth. The wireless technology used for the downlink channel operates at a higher data rate than the wireless technology used for the uplink channel. The controller controls data communications over the downlink channel and the uplink channel to maximise the downlink data communication QoS.
