20140044058 | COHERENT TRACKING AREA IN MULTI-MODE COMMUNICATION SYSTEMS - Systems, methods, and devices for providing aligned registration process and procedure for heterogeneous and/or overlaid access technologies within a network are described herein. In one innovative aspect, a method of generating and organizing wireless network access information is provided. The method includes receiving first information for a first area of a first radio access technology for a network. The method further includes receiving second information for a second area of a second radio access technology for the network. The method also includes receiving third information for the network. The method then includes generating, processing, and aligning a number of groups of first radio access technology location or registration identifiers coordinated with second radio access technology identifiers based at least in part on the received first, second, and third information. The groupings may be based on the quantity of devices, types of devices, and/or the number of physical access points. | 02-13-2014 |
20140198659 | CELL RANGE EXPANSION ELASTICITY CONTROL - In some aspects, a method for carrying out load balancing between cells in a heterogeneous network includes measuring loads within macro clusters in the network. The method additionally includes identifying one or more macro clusters experiencing unbalanced load conditions, and sending balancing indicators to one or more cells in the identified macro cluster(s). In other aspects, a method for carrying out load balancing in a heterogeneous network includes reporting cell loads within a macro cluster, and monitoring for balancing indicators. The method further includes responding to a balancing indicator by iteratively adjusting a value of an individual cell offset for a cell until one or more conditions is satisfied. Example conditions include accomplishment of handover, to or from the cell, of one or more low mobility User Equipment (UE), and making a determination that the value of the individual cell offset has reached a threshold prohibiting further adjustment. | 07-17-2014 |
20150045985 | EV ROUTE OPTIMIZATION THROUGH CROWDSOURCING - The present disclosure involves determining charging equipment availability through crowdsourcing. Information is gathered from a plurality of electrically powered vehicle in a geographical region. The charging stations in the geographical region are displayed. A request is received, from a user, to determine occupancy of the electrical charging equipment at one or more of the charging stations during a specified future time window. A calculation is performed based on the information gathered from the electrically powered vehicles. The calculation calculates a probability of the electrical charging equipment at the one or more charging stations being unoccupied during the specified future time window. As a part of the calculation, a weighted probability is assigned to each charging station of being visited by at least one of the electrically powered vehicles. The probability is communicated to the driver. | 02-12-2015 |
20150163701 | MANAGING VOICE CALLS IN CSFB DEVICES - The disclosure provides for managing voice calls in Circuit Switched Fall Back (CSFB) communication devices that are configured to make voice calls using both Circuit Switched (CS) networks and Internet Protocol (IP) over Packet Switched (PS) networks. The device may determine, when registered with a PS network, a signal strength of a CS network at the device. The device may select, based on the signal strength of the CS network, one of the CS network and the PS network for the voice call. The device may establish the voice call using the selected network. The device may receive a user request for initiating a voice call, and initiate a voice call over the selected network automatically using an application corresponding to the selected network. The device may also register with a voice over IP (VoIP) service over the PS network based on the signal strength of the CS network. | 06-11-2015 |
20150201360 | INTRA & INTER-FREQUENCY HANDOVER IN LTE WITH UPLINK AND DOWNLINK METRICS - Methods, systems, and devices are described for managing a handover of a UE based on consideration of both the uplink and the downlink channel conditions. A handover of a user equipment from a serving base station to a target base station may be held over, prevented or inhibited even if the downlink channel measurement events are triggered and reported based on consideration of the uplink and the downlink metrics. Such determination may also be based on weight factors associated with the uplink and the downlink metrics. The weight factors may communicate to the base station a relative value of the uplink and the downlink transmission for a user equipment. In other examples, a handover of the user equipment may be either initiated or held over based on a calculation of a loading delta that indicates an overall gain or loss that may be realized between the serving base station and the target base station. | 07-16-2015 |
20150201454 | VOLTE CALL SETUP - Methods, systems, and devices are described for call setup (e.g., VoLTE) for a wireless communication device. During a call setup procedure, the device may implement a “keep alive” mechanism to maintain an RRC connection established as part of the call setup procedure. The “keep alive” mechanism may be configured to insert some padding traffic (e.g., dummy packets) to maintain the RRC connection, for example, by restarting the network RRC connection release timer to prevent its expiration and release of the RRC connection during call setup. | 07-16-2015 |
20150230223 | USER EQUIPMENT (UE) AUTONOMOUS SWITCHING OF SIMULTANEOUS PHYSICAL UPLINK SHARED CHANNEL (PUSCH) AND PHYSICAL UPLINK CONTROL CHANNEL (PUCCH) TRANSMISSIONS - Certain aspects provide a method for autonomous switching of simultaneous physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH) transmissions by a user equipment (UE). A method for wireless communications by a UE is provided. The method generally includes determining whether a power limited condition exists and transmitting simultaneously on multiple uplink channels or transmitting on a single uplink channel based on the determination. | 08-13-2015 |
20150334612 | SMALL CELL CHANNEL SELECTION - Systems and methods for selecting an operating channel for a small cell are described. A determination can be made to select a different operating channel at a small cell based at least in part on at least one of a downlink quality metric or an uplink quality metric. One or more connected mode user equipments (UE) served by the small cell can be caused to handover to one or more neighboring cells, and one or more parameters configured to one or more idle mode UEs camped on the small cell can be modified to cause the one or more idle mode UEs to reselect to the one or more neighboring cells. The operating channel of the small cell can be switched to the different operating channel at least when the one or more connected mode UEs are handed over to the one or more neighboring cells. | 11-19-2015 |
