  • Patent number: 10129806
    Abstract: Aspects of the subject disclosure may include, for example, determining a demand for real-time services to a first mobile device, by way of a base station of an LTE system. In response, utilization of a first wireless channel of a first radio of the base station is evaluated. The first radio supports a first wireless service that includes the real-time service and a non-real-time service to a second mobile device within the same cellular region. A handover of the second mobile device to a second radio of the base station is facilitated in response to the utilization. The second radio is configured to support a second wireless service that excludes the real-time service within the same cellular region. Responsive to the handover, the second radio supports the non-real-time service over the second wireless channel to the second mobile device within the cellular region.

    Abstract: An enhanced RRC re-establishment procedure on secondary base station (SeNB) is proposed. A UE with dual connectivity is connected to both a master base station (MeNB) and a secondary eNB (SeNB). The UE performs radio link monitoring (RLM) and radio link failure (RLF) procedures over PCELL served by the MeNB. Once RLF is detected, the UE performs RRC connection reestablishment with a selected cell. From SeNB perspective, the SeNB triggers proactive fetching of UE context from the MeNB to ensure a successful reestablishment. From MeNB perspective, the MeNB provides preference information to the UE for selecting a suitable cell for reestablishment. From UE perspective, the UE considers its mobility state during cell selection such that smallcells are skipped for reestablishment when the UE has high mobility.

  • Patent number: 9888420
    Abstract: We disclose various embodiments of methods and apparatus for processing handovers of mobile terminals between base stations of a wireless communication system. An example handover algorithm used for this purpose enables the handover threshold to be increased for some mobile terminals, on a terminal-by-terminal basis, thereby individually expanding the range of the serving cell for each of such terminals. In an example embodiment, the handover-threshold determination is carried out based on physical-resource-block usage of the target cell. The extent of the cell-range expansion depends on whether or not the reference signals of the serving and target cells interfere with each other. Embodiments of the disclosed handover algorithm can advantageously reduce the number of failed handovers by allowing some communication sessions to run to completion before a handover is triggered.

  • Patent number: 9877247
    Abstract: A wireless communication system using cells to provide wireless access to services, comprising a first base station installed on board a public transportation vehicle to provide a moving cell, and a second base station installed at a stop at which users enter or leave the vehicle, to provide a fixed cell. A central controller guides handovers of users entering or leaving the vehicle. The first and second base stations to provide data concerning users to the central controller, and the central controller, over many journeys of the vehicle, gathers profile data of users based on the data provided by the base stations. As the vehicle approaches a stop, the central controller makes predictions about users likely to enter and leave the vehicle, and, provides guidance to the first and second base stations for performing handovers.

  • Patent number: 9867099
    Abstract: Embodiments of the present disclosure provide a cell access method, an apparatus, and a system, where the method includes: when user equipment camps on a first cell, receiving, by the user equipment, a first signal offset of the first cell and a random access failure threshold of the first cell; attempting, by the user equipment, to perform random access to the first cell, and counting a quantity of random access failures; and if the quantity of random access failures reaches the random access failure threshold, performing cell reselection, by the user equipment, by using the first signal offset for the first cell; and if no cell meets a service condition in cell reselection, performing cell reselection, by the user equipment, without using the first signal offset. Therefore, a service interruption problem of user equipment when random access to a cell fails in the prior art can be resolved.

  • Patent number: 9867212
    Abstract: A semi-persistent resource scheduling (SPS) allocation of a user equipment is deactivated in an LTE-based mobile communication system without requiring changes to the Physical layer-to-MAC layer interface and/or changes to PDCCH formats agreed by the 3GPP. A combination of NDI value and MCS index is defined that commands release of SPS resources. An alternative solution proposed defines a special transport block size that when signaled in a PDCCH commands release of SPS resources.

  • Patent number: 9848343
    Abstract: A method and system architecture for a self-organizing network (SON) includes a first cell having a first user equipment classifier for determining one of cell edge and cell central. The SON also includes a second cell having a second user equipment classifier for determining one of cell edge and cell central. The system architecture and method provide a first transmit time interval (TTI) schema for user equipment within the area of coverage associated with the first cell and a TTI schema for user equipment within the area of coverage associated with the second cell, the second TTI schema differing from the first TTI schema. The user equipment is classified as cell center or cell edge in dependence upon at least one of QoS requirement, geometry, periodic PSMM and CQI reports. The TTI schemas are used for “cell edge” user equipment by the respective cells.

  • Patent number: 9838908
    Abstract: The present invention is designed to use radio resources effectively and improve the throughput of a radio communication system even when a plurality of small cells are placed densely. A radio base station controls the connecting cell of a user terminal, and has a selection section that selects candidate cells, the received power and/or the received quality of which in the user terminal is equal to or greater than a predetermined value, and a determining section that calculates the amount of data to transmit to serving user terminals, for each candidate cell, by taking into account the frequency band that is used, and determines a candidate cell where the amount of data is small, as the connecting cell of the user terminal.

  • Patent number: 9832691
    Abstract: In some embodiments, a network node has an associated cell identifier (“cell ID”). The network node creates a primary synchronization signal (PSS), a first secondary synchronization signal, and one or more additional secondary synchronization signals. The combination of signals defines the cell ID. The cell ID is one of N possible cell IDs and N is determined by multiplying: a number of possible values for the PSS; a number of possible values for the first secondary synchronization signal; and for each additional secondary synchronization signal, a number of possible values for the additional secondary synchronization signal, such that N is greater than a legacy number of possible cell IDs determined by multiplying the number of possible values for the PSS and the number of possible values for the first secondary synchronization signal. The network node transmits the combination of the created signals.

  • Patent number: 9813942
    Abstract: A system and method to perform load-balancing and congestion control between a primary Radio Access Technology (RAT) and a secondary RAT. A broadcast message is sent to all User Equipments (UEs) operating under the secondary RAT. If the primary RAT is congested, a congestion indicator in the broadcast message prevents the UEs from idle re-selecting or switching to the primary RAT. Even if the primary RAT is not congested, the broadcast message may still include other parameters such as one or more probability values, a group identifier for the UE groups, and a retention timer. The idle UEs in the secondary RAT that generate device-specific random values that are equal to or greater than the applicable probability threshold value(s) are allowed to reselect the primary RAT. If an idle UE fails this probability test, it may not be allowed to reselect the primary RAT again until the retention timer expires.
