  • Patent number: 8521168
    Abstract: A method and corresponding system is disclosed for enhanced resource allocation in a wireless communication system. According to the method, when an idle wireless device seeks to initiate a call in a given coverage area, the device will provide with its initiation request to the serving radio network a motion specification indicating an extent of movement of the device, based on the device's tracking of its own movement. The network will then use that motion specification provided with the initiation request as a basis to determine whether to select a resource to allocate for the call in the given coverage area based on resource implementation in at least one neighboring coverage area or whether to instead select the resource to allocate without regard to resource allocation in the at least one neighboring coverage area.

  • Patent number: 8494542
    Abstract: A wireless communication network makes intelligent accept/reject decisions responsive to sector selection requests by mobile stations based on sharing per-sector loading information and per-sector mobile station received signal quality information. For example, the signal quality and sector loading information for each sector in a given mobile station's active set of sectors can be evaluated to determine whether the sector targeted by the mobile station for selection as its new serving sector for high-speed packet data service is the “best” sector for serving the mobile station. The network can identify the “best” serving sector based on one or more metrics. If the targeted sector is not the best one for serving the mobile station, the network sends a reject message, or it may send a redirect message pointing the mobile station to the best serving sector. The disclosed accept/reject processing advantageously applies to cdma2000 and W-CDMA networks, for example.

    Abstract: A method and apparatus is disclosed whereby location based information (LBI) is used to make access and routing decisions within a network. Such LBI is sent from mobile devices to the core network when the mobile device registers with the network and is updated periodically. Over time, this collected LBI data represents the position of mobile devices over time and periodic patterns of usage in different geographic areas. When a network receives an indication that a mobile device requires registration with the network, the network determines as a function of said LBI, a desired network access technology to use to connect said mobile device with the network. Instructions are then transmitted to the mobile device to establish a connection using said desired network access technology and the device is registered with the network. Dynamically updated LBI information from mobile devices is also used for IP network routing optimization.

    Abstract: A device detects poor coverage associated with a source radio access technology (RAT) with which the device is connected, and connects to a target RAT. The device also measures the source RAT for a time period after connecting to the target RAT, and sends, based on the measurements, one or more measurement reports to the target RAT, where the target RAT forwards the one or more measurement reports to the source RAT. Alternatively, or additionally, the target RAT may detect that the handover was triggered too early and may inform the source RAT or command the UE to return to the source RAT. The device further stops the measuring and the sending when the time period expires. In this way, IRAT handover parameters may be automatically or manually tuned to minimize the number of handovers triggered too early, which may result in a more efficient cell configuration.

  • Patent number: 8396477
    Abstract: Disclosed are a radio communication base station device and a radio communication method which can reduce the interruption time of a service being received by UE while suppressing a resource consumption amount in an SFN area when the UE performs a handover from the SFN area to a non-SNF area. An MBMS reception request identification unit (127) judges an RRC message inputted from the UE (100). If an MBMS reception request is contained, an MBMS reception request is transmitted to an MBMS reception request storage unit (124). Moreover, when the RRC message from the UE (100) contains an adjacent cell reception quality measurement result, a handover decision unit (126) judges whether to perform a handover to the adjacent cell. The MBMS reception request storage unit (124) stores the MBMS reception request outputted from the MBMS reception request identification unit (127).

  • Patent number: 8380190
    Abstract: A computer implemented method, apparatus, and computer usable program code for location-based tuning for a mobile wireless platform. A current geographic location of the mobile wireless platform is determined on a route being traveled by the mobile wireless platform. Radio frequency conditions are sensed in a path of the mobile wireless platform. Radio frequency conditions are detected at the current geographic location of the mobile wireless platform as the mobile wireless platform travels along the route. An optimal channel is determined for the current geographic location. The optimal channel maximizes communications of the mobile wireless platform based on the radio frequency conditions. The mobile wireless platform transitions channels to the optimal channel in response to determining the optimal channel. One or more wireless devices transition to the optimal channel to communicate with the mobile wireless platform.

  • Patent number: 8380170
    Abstract: A system for restricting operation of wireless devices, for example cell phones, comprises a controller and a plurality of sensors. The system restricts device usage, while permitting emergency phone calls, for example 911 calls. The sensors receive transmissions from devices, and use the transmissions for identification and determining whether a device is within a restricted zone. One disclosed method is triangulation, using time of arrival of transmissions at the sensors. If the device is within the zone, the controller sends device identification, and possibly a customized restriction request, to a remote node, for example a control node of a cell phone network operator. The operator then uses its network resources to implement the requested restrictions. Communication between the controller and the remote node is secure, possibly encrypted, to minimize malicious interference. A wireless control can define vertices of the zone and exempt certain devices from restrictions. Jamming is not required.

  • Patent number: 8380206
    Abstract: A user equipment UE reports its mobility state in signaling for establishing, re-establishing, or re-configuring a radio connection between the UE and a network access node. In one embodiment the reported mobility state is selected from among normal; medium and high. In another embodiment the reported mobility state informs of a number of cell changes the UE has performed within a predetermined evaluation period. The UE may also include an indication whether a hysteresis period for entering into a normal mobility state is running for the UE. The network configures the UE in dependence on the reported mobility state, such as setting a parameter for measuring or reporting neighbor cells (e.g., suspend a serving cell quality threshold as a condition for measuring/reporting; limit inter-frequency and/or inter-radio access technology reporting; set a shortest measurement reporting gap; disable an event trigger; and/or set layer 3 filtering of measurement results for faster reporting).
