Abstract: A method is disclosed, comprising: sending position information reflecting a current position of a base station to a coordinating server; receiving a warning request message from an operator core network containing an emergency area; calculating a geographic area corresponding to an emergency tracking area by translating the emergency area from a set of base stations to the geographic area; determining whether the base station may be outside of a threshold distance from the geographic boundary of the emergency tracking area; and sending the warning request message when the base station may be within the threshold distance from the geographic boundary of the emergency tracking area.

Abstract: In this invention, we disclose methods for enabling ad hoc cellular base station functionality within a user equipment when the connection quality between a base station and the user equipment is limited or nonexistent. These methods include measuring a connection quality between a user equipment and its serving base station. If the connection quality is below a threshold, the user equipment can enable its internal ad hoc cellular base station functionality. This is done by running a software within the user equipment that (a) checks the connection quality periodically, and (b) enables ad hoc cellular base station functionality of the connection threshold dips below a certain value. In one embodiment, that threshold could be the same threshold value that a user equipment would use if it were making a decision to handoff to another base station based on poor connection quality.

Abstract: A radio resource scheduler at a first base station may be configured to: identify radio frequency resources in use by the first base station, identify radio frequency resources to be reserved as virtual guard bands to reduce adjacent band interference, and install virtual guard band rules for reducing interference with adjacent bands. The virtual guard band information may be hints, allocations, priorities, reservations, or scheduling instructions for avoiding certain radio resources, radio resource blocks, or frequencies.
