    • A method for radio access offloading is disclosed, wherein the method comprises maintaining (302), in a user terminal (102), pre-configuration information on integrated local area radio access offloading layers. In response to detecting an access point (104) of an available offloading layer, the user terminal may activate (305) a local area radio access offloading mode. The user terminal (102) transmits (306), to the base station (101) via the access point (104), an indication indicating that the offloading mode is activated, and receives, from the base station (101), a confirmation (309) indicating that the activated offloading mode is accepted by the base station (101). The user terminal (102) then decides, whether or not to switch to the available offloading layer, wherein if the user terminal (102) decides to switch to the available offloading layer, offloading (311, 312) is performed via the access point (104).

    • The present invention concerns a method and a system for operating broadband public safety mobile communication. The method comprises providing a broadband public safety network PSN that comprises at least a first MS1 and a second MS2 mobile device and a first coverage area; and providing a broadband mobile communication network CN comprising a second coverage area 104. The method comprises detecting the first MS1 and second MS2 mobile devices are residing out of the first coverage area and residing in the second coverage area 104. Then the first MS1 and second MS2 mobile devices are starting to operate in a Device to Device mode 204. The method further comprises: defining a group comprising the first MS1 and second MS2 mobile devices that are communicating in the Device to Device mode. The inventive method comprises determining, by using a selection mechanism comprising one or several timers, which of the first MS1 and second MS2 mobile devices acts as a controlling mobile device for the group 202.
