    Abstract: The invention relates to method and structures for mobility policy e.g. in a Worldwide Interoperability for Microwave Access, WiMAX, based communication. According to embodiments, a method and devices for mobility control of a terminal are provided wherein a mobility policy parameter defines the mobility control of the terminal. The mobility policy parameter preferably is part of a mobility policy or subscription record stored for a subscriber of the terminal in a subscriber data base. The mobility policy parameter may include at least one of an indication of mobility restriction, possibly indicating included or excluded cells or areas etc; an indication of fixed access, indicating a fixed base station to which the subscriber has to request access; nomadicity, indicating that no handover is allowed for that particular subscriber; and restricted mobility limited to a group of base stations or areas. Embodiments allow to deploy mobile WiMAX for fixed access applications, enabling reuse of existing technology and further development towards full mobility.

    Abstract: Various embodiments are disclosed relating to the optimization of handovers and ranging in a wireless network. According to an example embodiment, an information request may be received, which may include a handover information request, such as a ranging request for handover. Resources for handover information requests may be allocated or applied at a higher priority level than at least some non-handover information requests. Further, a mobile station may perform ranging with a base station, wherein a first value of a retransmission timer at the mobile station is used for non-handover ranging, and a second value of the retransmission timer that is less than the first value is used for handover ranging. Further, a ranging request message including a ranging purpose indication indicating a ranging purpose may be received. Resources for processing the ranging request message may be allocated at a priority level based on the ranging purpose indication.

    Abstract: In a system for processing an emergency session in a WiMAX (worldwide interoperability for microwave access) network system including a home network, at least one roaming network and at least one mobile station, an emergency call is established between the mobile station and the home network in case the mobile station is located in the home network, or between the mobile station and a roaming network (visited network) in case the mobile station is located in the roaming network. In a different embodiment, the location of a mobile station is determined in response to an emergency location request and the location (geographic) coordinates are provided in order to establish an emergency call setup.
