    Abstract: Systems, methods and computer software are disclosed for scheduling System Information Blocks (SIBs). A Master Information Block (MIB) is transmitted at a first fixed cycle; starting from a first System Frame number (SFN). A first SIB is transmitted at a second fixed cycle and at a SIB offset after the SFN. Other SIBs are transmitted at cycles specified by a SIB scheduling information element in the first SIB.

    Abstract: A method for localizing a voice call is disclosed, comprising: receiving an originating leg setup message for an originating leg bearer from the first base station for a first user equipment (UE); creating a first call correlation identifier and storing the first call correlation identifier in association with the first UE; extracting a second call correlation identifier from a terminating leg setup message for a terminating leg bearer received from the core network; determining a real time protocol (RTP) localization status for the originating leg bearer and the terminating leg bearer based on matching the second call correlation identifier of the terminating leg against the stored first call correlation identifier of the originating leg; and sending transport layer assignment messages to the first base station to redirect RTP packets from the first UE to the second UE via the terminating leg bearer without the RTP packets transiting the core network.

    Abstract: Systems and methods for handovers with simplified network topology are disclosed. In a first embodiment, a method is disclosed, comprising: at a coordinating gateway during a handover of a mobile device from a first base station to a second base station, receiving a first handover request from the first base station; discarding a first shared security key received in the first handover request; sending a tunnel switching request to a core network node; obtaining precursors for a second shared security key from the core network node in a response to the switching request; sending a second handover request to the second base station with the precursors to calculate the second shared security key for securing a data connection for the mobile device following the handover; deriving the second shared security key from the obtained precursors at the first base station; and deriving the second shared security key from the obtained precursors at the coordinating gateway.
