    Abstract: Deploying multiple access points on multiple wireless communication channels to optimize coverage area. Additional channels provide additional communication capability which multiple AP's, and their associated stations, can collectively use. An additional set of AP's can be disposed in the additional communication channel, with multiple communication channels possibly physically intersecting. The system control element collects information from devices in the wireless communication system, and automatically configures which AP is assigned to which communication channel. The system control element determines which AP's are servicing which physical locations, in response to feedback from AP's and stations in those locations. The system control element assigns, or re-assigns, AP's in each physical location, with the effect of optimizing coverage.

  • Patent number: 10313946
    Abstract: Dynamic cell resource management in wireless networking. By way of example, user terminal access parameters can be dynamically modified based on changing load conditions at one or more cells of a wireless network. For instance, resource capacity of a wireless network cell can be monitored over time to identify a potential resource overload condition. If such a condition occurs, a load management algorithm can be executed that progressively restricts or de-restricts user terminal access parameters based on changing load conditions. In particular aspects, the load management algorithm can analyze relative cell load of neighboring cells to implement coordinated load sharing. By dynamically modifying user access parameters, traffic can be directed toward or away from cells operating at low or high capacity, respectively.

    Abstract: Methods, systems, and devices are described for decreasing user plane latency in a wireless communication system. This may include routing a portion of bearer traffic to or from a UE through a local or serving gateway, or within or between base stations, rather than via the core network. In some examples, techniques for selected internet protocol flow ultra-low latency (SIPFULL) for systems in which users may have subscribed to enhanced services may be employed. The network may, for instance, authorize SIPFULL functionalities for UEs per access point name (APN) based on individual services subscribed by the UE to improve overall quality of service (QoS). In some examples, a UEs latency requirements or SIPFULL authorizations may affect mobility operations.

A ceiling level can be a predetermined cap on transmission power for downlink or uplink channels between a user equipment and a base station. Where there is sufficient headroom in total transmission power and a power level greater than the predetermined ceiling can be effective, the ceiling can be adjusted to greater values than the predetermined value. Where total transmission power is more committed, ceiling adjustment can be prevented. Further, where there is no adequate benefit from increasing the ceiling, the adjustment of the ceiling can be prevented. While some instances can result in optimized transmission levels below the ceiling, instances can also be accommodated where the ceiling is to be increased.

  • Patent number: 10285203
    Abstract: In an example of wireless communications, a transmitting station may set multiple network allocation vectors (NAVs) to reserve a communication medium for transmitting a frame in the amount of time indicated by the NAVs. A receiving station that receives a frame may identify which NAV is intended to be set by the receiving station. The receiving station may update a first type of NAV with duration information from the frame when the frame is received from a same wireless network, and update a second type of NAV with duration information from the frame when the frame is received from a different wireless network. The receiving station may ignore setting the NAV when the frame is received from the different wireless network. Alternatively, the receiving station may not ignore setting the NAV when the frame is received from the same wireless network. Other methods, apparatus, and computer-readable media are also disclosed.

  • Patent number: 10285088
    Abstract: Systems and techniques for minimize drive testing measurements. Network elements including UEs and eNBs are configured to define measurement procedures to determine control plane latency affecting scheduling requests, RACH procedures, and combinations thereof. Upon initiation of a request for uplink resources, such as a scheduling request or a RACH procedure, a UE notes the time of the request and measures the time until its fulfillment. If a scheduling request fails, a RACH procedure may be performed and in such cases, the time from initiation of the scheduling request, through its failure, until successful completion of the RACH procedure may be measured. Once a measurement has been made, the measured duration and other associated information are assembled and analyzed, and when the measurement and other information meets criteria for inclusion in a measurement report, the report is assembled and sent, or logged for sending, to an eNB.

  • Patent number: 10285106
    Abstract: The present invention provides user equipment and a method for ensuring continuous service reception in a wireless network. User equipment (UE) obtains configuration information of a neighboring cell; the UE determines that at least two cells of all cells including the serving cell and the neighboring cell belong to a same area to which a same multimedia broadcast multicast service belongs; and during measurement of a reference signal, the UE combines reference signal measurement values of at least two cells that belong to the area of the same multimedia broadcast multicast service to obtain a combined measurement value, and compares the combined measurement value with a measurement value of another cell, so as to determine whether to perform reselection. Therefore, in a handover determining process, radio signal quality of a single cell is prevented from being underestimated, so that an unnecessary handover procedure is avoided, thereby ensuring quality of a radio signal obtained by UE.

  • Patent number: 10278102
    Abstract: A correspondence information storage 32 acquires correspondence information in which an eNB 20, an SGW-C 60, and an SGW-U 70 are associated with each other in advance, and a connection controller 31 receives a handover request from the eNB 20 and identifies a target eNB 20 and a source eNB 20. A connection changer 33 identifies the SGW-C 60 and the SGW-U 70 associated with the target eNB 20 and identifies the SGW-C 60 and the SGW-U 70 associated with the source eNB 20, with reference to the correspondence information. The connection changer 33 determines whether or not the SGW-C 60 and the SGW-U 70 are to be changed on the basis of the identified result, and controls change requests for at least one of the SGW-C 60 and the SGW-U 70 on the basis of a result of the determination.

  • Patent number: 10278100
    Abstract: A Long Term Evolution (LTE) Mobility Management Entity (MME) manages a service level for an Internet Protocol Multimedia Subsystem (IMS) media session for a User Equipment (UE). The MME exchanges first control data with the UE to establish an IMS signaling bearer and a media session bearer. The MME identifies a UE hand-over between LTE access nodes during the IMS media session and determines an access technology difference between the LTE access nodes. The MME determines when the service level for the IMS media session should be modified based on the access technology difference and exchanges service modification data with the IMS. The MME exchanges second control data with the UE to indicate a modification to the service level for the IMS media session.
