Apparatus, systems and methods for an enhanced handover mechanism and cell re-selection
A user equipment (UE), base station and a corresponding method for receiving historical data from a diagnostic server, receiving location data of the UE, determining a probability of a failed handover during a call based on the historical data and the location data, comparing the probability of the failed handover to a threshold value and initiating a call handover to a wireless local area network when the probability of the failed handover exceeds the threshold value. Also, a UE, base station and corresponding method for determining if one or more UEs have an active voice over WiFi call or if the UEs are registered with a Internet protocol (IP) multimedia subsystem (IMS) over WiFi and biasing a cell reselection procedure of the UE to select a cell of a packet switched network such as LTE.
REROUTE NETWORK TRAFFIC FROM MILLIMETER-WAVE LINK TO WLAN TRANSMISSION
In some examples, a computing device may comprise a processing resource and a memory resource storing machine-readable instructions to cause the processing resource to proactively identify a line-of-sight (LOS) blockage of a network signal transmitted on a millimeter-wave link, and reroute network traffic from the millimeter-wave link to a wireless local area network (WLAN) transmission channel in response to identifying the LOS blockage of the network signal.
Inter-small cell handover method, device, and system
The present application relates to the field of communications technologies, and provides an inter-small cell handover method, a device, and a system. When UE is in a coverage hole of a serving small cell, the UE needs to perform synchronous measurement only on each available beam pair in a set of available small cells determined by the UE, thereby reducing a delay of re-accessing a high frequency network by the UE, and improving QoS of receiving a high frequency service by the UE. the present application includes: performing, by UE, synchronous measurement, to determine a set of small cells available for the UE; sending the set of available small cells to a macro base station; when the UE is in a coverage hole of a current serving small cell, receiving, by the UE, a first synchronization indication sent by the macro base station.
METHODS AND APPARATUS FOR DYNAMIC CONTROL AND UTILIZATION OF QUASI-LICENSED WIRELESS SPECTRUM
Methods and apparatus for providing quasi-licensed spectrum access within an area or venue. In one embodiment, the quasi-licensed spectrum utilizes 3.5 GHz CBRS (Citizens Broadband Radio Service) spectrum allocated by a Federal or commercial SAS (Spectrum Access System) to a managed content delivery network that includes one or more wireless access nodes (e.g., CBSDs and APs) in data communication with a controller. In one variant, the controller dynamically allocates (i) spectrum within the area or venue within CBRS bands, and (ii) MSO users or subscribers to CBRS bands or WLAN (e.g., public ISM) bands in to manage interference between the coexisting networks, and maximize user experience. In another variant, the controller cooperates with a provisioning server to implement a client device application program or app on MSO user or subscriber client devices which enables inter-RAT access.
Aggregation of data bearers for carrier aggregation
Multiple data bearers may be configured for a user equipment (UE) for carrier aggregation and may be split among multiple evolved nodeBs (eNBs). The eNBs may be selected to serve the multiple data bearers for the UE based on various criteria such as channel conditions, loading, and the like. Various eNBs may be selected to serve data bearers for UE on a per data bearer basis, so that a particular eNB may be selected to serve each data bearer of the UE. Each data packet for the UE may then be sent via an appropriate data bearer.
Method and apparatus for cell reselection
In cellular communication systems, the success rate for incoming calls for a client terminal in idle mode is related to the successful reception of paging messages. The instances for paging message transmission, known as paging occasions, may be based on a client terminal's unique identity. The network transmits a paging message addressed to a specific client terminal in its specific paging occasion. In addition to the reception of paging messages, a client terminal may be required to search and monitor neighbor cells for cell reselection and handoffs. A method and apparatus are disclosed that improve the cell reselection by using the known a priori information to categorize the neighbor cells, to categorize the cell reselection types, and to perform cell reselection to an appropriate neighbor cell at the opportune time such that a paging message reception may be neither missed nor delayed during the cell reselection.
APPARATUS AND METHOD FOR EFFICIENT HANDOVER FOR LOW EARTH ORBIT (LEO) SATELLITE SYSTEMS
Approaches for efficient, dynamic and continuous handover processes, which encompass selection of an optimal path (consisting of a satellite, a satellite beam and carrier frequency set) over which a mobile user terminal (UT) communicates with the radio access network in a mobile satellite communications system, are provided. A set of path factors are determined regarding each of a plurality of communications paths for the UT. A path selection metric (PSM) for each communications path is determined, wherein the PSM for each communications path is determined via a weighted calculation based on the respective set of path factors for the communications path. A decision is made as to whether to perform a handover of the UT from a first of the communications paths to a second of the communications paths, wherein the determination is based on an evaluation performed based at least in part on the PSM.
ANALYTICS DRIVEN WIRELESS DEVICE SESSION CONTEXT HANDOVER IN OPERATOR CLOUD
A method and apparatus for analytics-driven wireless device session context handover in an operator cloud are provided. According to one aspect, some embodiments include a method for a network node to determine whether to perform a wireless device session context handover. The method includes determining, at the network node, a first cost of not handing over a wireless device session context based at least in part on a calculated estimate of time the wireless device will stay associated with a current base station and a calculated estimate of a cost per unit time of not performing the handover. The method also includes determining, at the network node, a second cost of handing over the wireless device session context based at least in part on at least one of context-related data, base station load, backhaul load and backhaul delay.
OPPORTUNISTIC BALANCING IN MULTIPLE LINKS
Systems and methods are provided for opportunistic load balancing across one or more communication links supported by one or more base stations. As part of the opportunistic load balancing process, a load balancer may measure a performance metric and an idle capacity metric for the one or more communication links. In some embodiments, the load balancer may directionally measure the performance metric and the idle capacity metric. Based on the measured metrics, the load balancer may determine a candidate base station for a network socket. The load balancer may then establish the network socket with the candidate base station. As a result, the load balancer may help alleviate network congestion.
