  • Publication number: 20150094067
    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 a determination that the user equipment entered a first RRC state from a second RRC state, the controller delays performing a cell search until the controller determines that the user equipment has received complete system information for a serving cell.

  • Patent number: 8682333
    Abstract: A method and apparatus for processing a message in a mobile, telecommunications device. The method comprises: receiving a Cell Update Confirm (CUC) message; determining whether the device has an empty C_RNTI variable; when the device has an empty C_RNTI variable, determining whether the CUC message includes a new C_RNTI; when the CUC message includes a new C_RNTI and the CUC message would cause the device to enter a state which requires the UE to respond to the message before entering the state, carrying out at least one further step prior to entering the state.

  • Publication number: 20140051415
    Abstract: Examples of reducing data transfer latency caused by state transitions in mobile networks are disclosed. A first disclosed example method comprises, while operating in a first state having fewer available radio resources than would be available in a second state, setting a traffic volume indicator if a wireless device determines that a radio link control (RLC) buffer occupancy is larger than a traffic volume measurement threshold, and sending the traffic volume indicator to a network in a transmitted message other than a CELL UPDATE message having uplink data transmission as an update cause. A second disclosed example method comprises, while operating in a first state, receiving a message that is to cause a wireless device to transition to a second state having fewer available radio resources than are available in the first state, and rejecting the message if the wireless device has pending uplink data to send to a network.

  • Patent number: 8554266
    Abstract: Mobile user equipment for use in a cellular communications environment performs an improved cell selection on transitions out of a connected mode state. The transitions might be from one connected mode state to another or from a connected mode state to idle mode. The improvement in cell selection lies in assembling the list of candidate cells prior to cell selection. In the prior art, the list of candidate cells would usually be restricted to the serving cell or active cells supporting communication between the equipment and the network prior to transition. In embodiments of the invention, the list might comprise cells which are not the serving cell or which are outside the active set, for example a network-preferred cell or cells neighboring the serving cell or cells of the active set.
