    Abstract: A method of searching of base stations in a mobile communication system has a first stage of detecting at least one slot boundary, a second stage of detecting at least one frame boundary and a scrambling code group, and a third stage of detecting a scrambling code. Multiple possible base stations are identified by determining a first threshold based on correlation values of correlating the input signal with a primary synchronization channel code. For each hit, the input signal is aligned to the corresponding slot boundary, an average correlation value is based on all correlations with secondary sequences, and a second threshold based on the average correlation value is set. Any delay and codewords that have a correlation value above the second threshold are correlated with the codes in the detected group so as to determine multiple base stations.

Then, the wireless device determines if the one or more PLMNs indicated in the first system information exclude all PLMN(s) supported by the wireless device (121). When the one or more PLMNs indicated in the first system information does not exclude all PLMN(s) supported by the wireless device (121), then the wireless device receives a second system information comprising the one or more PLMNs supported on the frequency carrier by the network node (110). A wireless device (121) for receiving system information is also provided. Further, a network node and a method therein for transmitting system information are also provided.

  • Patent number: 9986491
    Abstract: Disclosed is a method for scanning for an access point in a wireless LAN system. An active scanning method comprises the steps of: transmitting a probe request frame to an access point; and receiving, from the access point, a probe response frame corresponding to the probe request frame. The probe response frame may include time information of a beacon transmitted after the probe response frame. Thus, the efficiency of a wireless channel can be improved in a wireless LAN system.

  • Patent number: 9980188
    Abstract: In a wireless network including a first cell and a second cell, it is determined whether a measure of mobility of a user device meets a mobility criterion, and it is determined whether a size of the second cell meets a cell size criterion. When it is determined that (i) the measure of mobility of the user device meets the mobility criterion and (ii) the size of the second cell meets the cell size criterion, the user device is prevented from being switched from the first cell to the second cell, or at least one of (i) a handover parameter or (ii) a cell reselection parameter is adjusted in order to change a probability that the user device will switch from the first cell to the second cell.

  • Patent number: 9980275
    Abstract: A multi-subscriber identity module (SIM) wireless communication device performing early camping in initial cell selection or reselection may detect an active communication on a modem stack associated with a first SIM, and a condition requiring initial cell selection/reselection on a modem stack associated with a second SIM. In response to receiving a paging message for the second SIM, the wireless communication device may trigger a radio resource to tune to a frequency of an identified target cell of the second SIM, receive a first portion of system information broadcast by the identified target cell, and determine whether initial cell selection/reselection to the identified target cell is complete. In response to determining that initial cell selection/reselection to the identified target cell is not complete, the wireless communication device may save the received paging message, and raise a priority level for the activity on the modem stack associated with the second SIM.

  • Patent number: 9980314
    Abstract: The proposed approach contemplates systems and methods configured to transmit signals irregularly (sparsely) over a mobile communication network (carrier) in which reception gaps apply while increasing the likelihood that receivers will receive a signal at least once during a certain time period, called irregular signal period. First, a set of transmission offsets is selected, the transmission offsets defining a relative transmission time in a burst, such that if a burst would be transmitted using the selected transmission offsets, a receiver with any valid reception gap configuration would receive at least one signal in its whole duration. Then, during an irregular signal period, signals are transmitted in a sequence of one or more consecutive bursts using each of the transmission offsets in the selected set at least once, wherein the sequence of bursts may be preceded and/or followed by a period of no signal transmission.

  • Patent number: 9973977
    Abstract: A system and method of supporting packet-switched handover of a mobile station (MS) from a GERAN/UTRAN cell to a Generic Access Network (GAN) cell within a GAN. If the MS is within coverage of the GAN cell, the MS registers within the GAN, triggering initiation of the packet-switched handover from the GERAN/UTRAN cell to the GAN cell. A preparation phase is then conducted for executing the packet-switched handover. The preparation phase includes identifying the MS context as part of the preparation phase and activating the GA-PSR TC towards the MS. Next, the packet-switched handover is executed, resulting in the MS switching to GAN mode. The MS then begins transferring packets via the GAN cell. The system and method also supports a packet-switched handover from the GAN cell to the GERAN/UTRAN cell.
