    Abstract: Methods of communicating location information from a subscriber to a repeater are described. The subscriber switches from a working channel to a data revert channel, transmits a request for a periodic or one-time window to transmit an update, and determines from grant information in the response announcement the allocated window and frame before switching back to the working channel. Before the allocated time, the subscriber switches to the data revert channel, confirms whether it remains scheduled to transmit the update from a repeater announcement, and if so transmits the location update in either the current or reserved window. The announcements from the repeater contain the identity of the next window and frame and the subscriber reserved to use the window in addition to grant information.

  • Patent number: 9167447
    Abstract: A method of failure event reporting for initial connection setup failure is proposed. In one embodiment, a UE first camps in RRC_IDLE mode in a cell served by a base station. The UE then detects a connection setup failure when performing a random access channel (RACH) procedure with the base station in an RRC connection attempt. The UE records a failure event report when the RACH procedure fails. Later, the UE transmits the failure event report to the network in RRC_CONNECTED mode. The failure event report comprises information that refers to the earlier RRC connection attempt. The failure event report also comprises available location information or available mobility measurements at the time the initial connection setup failure occurs. Based on the failure event report, the network can adopt corrective actions accordingly to mitigate the failure.

  • Patent number: 9137002
    Abstract: A method and system that allows a mobile station of a communications system to request and be granted a fraction (a sub-set) of the overall frequency bandwidth of a communications channel for its transmissions. Thus, for example, in a TETRA system, a mobile station can, instead of having to request and be granted the full frequency bandwidth of an, e.g., 150 kHz QAM channel, request and be granted only a portion or fraction of the 150 kHz bandwidth of the channel, such as a 25 kHz portion of it. This allows the requested and allocated transmission resources to be more readily optimized to the amount of data that a mobile station wishes to transmit.

  • Publication number: 20150148043
    Abstract: A method of wireless communication includes recording an absolute system frame number (SFN) of a target radio access technology (RAT) and/or recording a relative system frame number (SFN) difference between a serving radio access technology (RAT) and the target RAT. A transmission time interval (TTI) boundary, is determined after redirection, based at least in part on the recorded absolute frame number (SFN) and/or the recorded relative system frame number (SFN) difference.

  • Publication number: 20150148045
    Abstract: The present invention is a method and system for station location based neighbor determination and handover probability estimation. A serving access point determines the location and movement measurements of a station (STA). Neighboring access points report coordinates of cell fringes of the neighboring access points. The STA sends a request for system information to the current access point along with current location of the STA. The current access point provides the system information, and the STA utilizes the system information to determine best handover candidate from among neighboring access points and an estimate of the time for handover.

  • Patent number: 9042939
    Abstract: A portable electronic device and a method of controlling are disclosed, each of which is capable of efficiently selecting a communication processing unit. The portable electronic device includes: a first communication processing unit conforming to a first communication scheme; a second communication processing unit conforming to a second communication scheme; a third communication processing unit conforming to a third communication scheme; and a control unit. When data communication is performed, the control unit controls each processing unit so as to preferentially use the first communication processing unit, the second communication processing unit, and the third communication processing unit in this order. In a case in which a network is disconnected while data communication is being performed by the second communication processing unit, the control unit executes control so as to continue the data communication by the third communication processing unit.

  • Patent number: 9042888
    Abstract: A mobile wireless device maintains a radio sector database. When receiving no response or a negative response from a radio sector to a transmitted signaling message, the mobile wireless device adds or updates the radio sector database. When receiving a positive response from the radio sector, the mobile wireless device deletes the radio sector from the radio sector database. Before transmitting signaling messages to a radio sector, the mobile device determines a time delay value if the radio sector is in the radio sector database. The mobile wireless device discards the signaling message when an elapsed time since a most recently transmitted signaling message to the radio sector does not exceed the determined time delay value. In an embodiment, each radio sector in the radio sector database includes a failure count value, and the determined time delay value depends on the failure count value.

  • Publication number: 20150141017
    Abstract: The various embodiments provide methods for implementing a forced reselection strategy after causing colliding subscriptions to perform reselection to neighboring cells. In various embodiments, the MSMS communication device may undo the effects of forced reselection in certain situations when continuing to employ forced reselection may be ineffective. In other embodiments, the MSMS communication device may force reselecting subscriptions to reselect to neighboring cells in a paging group based on the page timings of the neighboring cells. Thus, the various embodiments may increase the performance of the colliding subscriptions and may enhance the user's overall experience.

The method includes: determining target component carriers to which a User Equipment (UE) is to be handed over, and notifying the UE of information about the target component carriers through a source eNB; and after receiving a dedicated random access preamble sent by the UE, sending a random access response message on at least one component carrier in the target component carriers. The terminal equipment includes: a handover command receiving unit, a sending unit, and a random response receiving unit. Therefore, in a random access procedure of cell handover, the eNB is capable of determining downlink component carriers that a UE monitors, thereby increasing utilization rate of downlink resources.

  • Patent number: 9037139
    Abstract: A wireless communication device (WCD) may transmit a first sequence of access probe messages to a radio access network (RAN) via a first wireless coverage area. The WCD may then transmit a second sequence of access probe messages to the RAN via a second wireless coverage area. Based on the first wireless coverage area being more preferable to the WCD than the second wireless coverage area, the WCD may use a negative inter-sequence power step for the power levels at which the WCD transmits the access probe messages of the first and second sequences. Thus, the WCD may transmit the first access probe message of the second sequence at a lower power than the first access probe message of the first sequence.
