Latest Patents

One of Hansén's latest patents is focused on the "Transfer of security association during a mobile terminal handover." This innovation ensures that an existing security association is re-established when a communication handover event occurs in a radio communications system, such as IEEE 802.11 or HIPERLAN. The process maintains the security association between a mobile terminal and a wireless communication network during the handover. Authentication during this event is achieved through a challenge/response procedure, where each member of the communication pair—comprising a new access point and the mobile terminal—sends challenges to one another and verifies responses before payload communication begins.

Another significant patent by Hansén is related to "Routing decision in connection-oriented packet network." In this invention, when a connection set-up message addressed to a mobile terminal arrives at a switch that supports mobility management, the switch determines whether to inquire about the terminal's temporary address based on the resources needed for the connection. This decision-making process is crucial for optimizing network performance and resource allocation.
