METHOD PERFORMED BY A WLAN NODE IN AN INTEGRATED WIRELESS COMMUNICATIONS NETWORK, FOR APPLYING SECURITY TO RECEIVED TRAFFIC DATA.

摘要

A wireless local area network, WLAN, node (400) is adapted to be comprised in an integrated wireless communications network comprising a WLAN and a cellular communications network. The WLAN node (400) comprises a receiving module (401) adapted to receive traffic data signals from a wireless device. A security module (403) is adapted to process the received traffic data signals and apply a first security protocol to a first traffic data signal received from the wireless device and a second security protocol to a second traffic data signal received from the wireless device. A routing module (405) is adapted to route the first traffic data signal to a node of the cellular communications network and route the second traffic data signal to a node of the WLAN. In one example the the security module is adapted to concurrently process the first traffic data signal and second traffic data signal from the wireless device, and the routing module (405) is adapted to concurrently route the first traffic data signal and the second traffic data signal to their respective nodes.
