  • Patent number: 8971892
    Abstract: A user equipment capable of performing reselection in a wireless network is disclosed. The user equipment comprises: 1) a controller configured to perform reselection between cells according to a priority-based reselection (PBR) algorithm using priority information; 2) transceiver circuitry configured to operate in cells using at least one radio access technology and to receive incoming messages including the priority information; and 3) a memory configured to store the received priority information. The controller is further configured to compare the received priority information with defined limits stored in the memory and to determine if the received priority information exceeds the defined limits.

  • Patent number: 8934899
    Abstract: A user equipment is provided comprising: 1) transceiver circuitry configured to operate in cells associated with at least one radio access technology (RAT) network; and 2) a controller configured to perform neighbor cell searches. The controller is further configured to determine when the user equipment enters a first RRC state from a second RRC state. In response to the determination, the controller determines a time period since a most recent search of neighbor cells was performed. The first RRC state is one of at least: CELL_PCH, URA_PCH and IDLE. The second RRC state is one of at least CELL_FACH and CELL_DCH.

  • Patent number: 8897190
    Abstract: A method for communicating with a mobile station is presented. The method includes transmitting a first radio block to the mobile station. The first radio block including an indication instructing the mobile station to enter a DTR mode. Before receiving an indication of whether the mobile station is in DTR mode, the method includes retransmitting to the mobile station at least one of the first radio block and a radio block previously transmitted to the mobile station using a timeslot that is not monitored by the mobile station when the mobile station is in the DTR mode.

  • Publication number: 20120220287
    Abstract: Methods and systems for slow associated control channel signaling are disclosed. An example method for securing communications in a mobile network disclosed herein comprises transmitting a first variant of a message of a first type on a first slow associated control channel (SACCH) before ciphering is started on the first SACCH, and after ciphering is started on the first SACCH, transmitting a second variant of the message of the first type on the first SACCH, and subsequently transmitting the second variant of the message of the first type on the first SACCH, wherein the subsequently transmitted second variant of the message of the first type is the next transmitted message of the first type on the first SACCH.
