Abstract: The disclosure relates to accessing a communication system. In accordance with the disclosed method a communication device communicating in a first access system based on an address is transferred to a second access system. The communication device sends an indication that the same address is to be used in the second access system, where after, if proxy mobility is available for the address, the same address is used for communications in the second access system.

Abstract: A method, apparatus, and computer program for managing network connectivity are disclosed. After successfully establishing a radio connection with an access point, a wireless apparatus using the radio connection to access a network beyond the access point is configured to carry out a network connection test. If the network connection test fails, the access point is blacklisted for a determined time period defined by a timer counted in the wireless apparatus.

Abstract: The present invention relates to a method for informing changed link properties in a system in which a mobile node is communicating by IP (Internet Protocol) with a correspondent node and utilizing a first link layer configuration. A need to change link layer communication to use a second link layer configuration is detected. Property information indicating a link layer property applied or to be applied in communication utilizing the second link layer configuration is defined. The property information is transmitted to the correspondent node. At least one setting for communication between the correspondent node and the mobile node is adapted in the correspondent node on the basis of the received property information.

Abstract: A system can include an access router and a proxy mobile internet protocol aware client mobile internet protocol node. The access router can include a storage unit configured to store a local care-of-address. The access router can also include a sending unit configured to send the proxy mobile internet protocol aware client mobile internet protocol node the local care-of-address. The proxy mobile internet protocol aware client mobile internet protocol node can include a receiving unit configured to receive local care-of-address from an access router. The proxy mobile internet protocol aware client mobile internet protocol node can also include a processing unit configured to process the local care-of-address.
