Systems and techniques for routing frames in one or more radio access networks based on a physical addressing scheme involve assigning a unique identifier to a virtual local area network that includes a path connecting an access point to a radio network serving node. For each of multiple nodes in the radio access network, the virtual local area network is associated with a port for routing frames towards the radio network serving node and/or a port for routing frames towards the access point. Frames that include a destination address associated with a mobile station associated with the access point are unicast from the radio network serving node towards the access point using the virtual local area network.

Seamless mobility in layer 2 radio access networks

The invention concerns a method for fast determination of the quality of the radio link from a mobile terminal (STA) to an access point (AP) in a Wireless Local Area Network whereby after having received a probe request message (PRU) from the mobile terminal (STA), the access point (AP) does not send a probe response message (PRE) to said mobile terminal (STA), a mobile terminal (STA), an access point (AP) and program modules therefore.

Method for fast radio link measurements of access point candidates for WLAN handover, a mobile terminal, an access point and program modules thereof

A protocol gateway for setting up multimedia sessions between a first terminal, using a first protocol (for example H.323), and a second terminal, using a second protocol, said first protocol requiring the determination of a master, which protocol gateway is characterized in that it has available to it means for forcing said first terminal to assume the role of master.
