A management device is connected with a plurality of relay devices, and the relay devices store data collected by a device. The management device registers, when a connection notification is received from one of the relay devices, relay device identification information, which identifies the relay device, of the relay device serving as the request destination when the data is acquired, sends a data acquisition request to the specified relay device, and sends, to one of the relay devices, relay device identification information of the target relay device targeted for deletion. The plurality of the relay devices associates, when the identification information targeted for the deletion is received, inquiry destination information specifying the target relay device with the data, and performs, when the data acquisition request is received, response control of the data on the basis of the determination of whether the inquiry destination information is associated with the data.

The present methods and apparatuses may select to a cell associated with a radio access technology (RAT) in response to performing a first procedure, the first procedure including at least one of a cell selection procedure, a cell reselection procedure, or a handover procedure. The present methods and apparatuses may further acquire one or more parameters associated with the selected cell identified by a cell global identity (CGI). The present methods and apparatuses may further determine that the CGI of the cell corresponds to a stored CGI of a previous cell. Moreover, the present methods and apparatuses may perform at least one second procedure based on determining that the CGI of the cell corresponds to the stored CGI of the previous cell, the second procedure including a communication configuration procedure based at least on the one or more parameters.

The disclosed subject matter relates to received signal strength indicator (RSSI) snapshot analysis. RSSI snapshot analysis can be independent of determining location/map information. An RSSI snapshot can be analyzed in view of historic RSSI information to determine a probability that a local wireless resource correlated with the historical RSSI information is within the service area of the user equipment. Machine learning can be employed to train an inference component to facilitate in determining the probability. In an aspect, the state of a wireless radio can be controlled based on the probability, which can reduce the energy consumption of the user equipment by facilitating selective enablement of a wireless radio.

Method and devices for optimizing wireless network connections in transportation vehicles are provided. An onboard computing device in a transportation vehicle identifies blackout area with severe wireless signal interference caused by nearby wireless access points in the blackout area. The wireless interference can be remedied by dynamically switching wireless channel for the in-vehicle wireless connection between the onboard computing device and a mobile device in the vehicle. The wireless interference can also be remedied by pre-caching the data needed for a content presentation during a time period when the vehicle travels within the blackout area.

A method of controlling admission of a user equipment to a cell of a multi-mode base station, being a base station arranged to operate as a plurality of cells, the plurality of cells comprising at least a first cell and a second cell, and the method comprising: determining information relating to the first cell, and controlling admission of a user equipment to the second cell in dependence on the information relating to the first cell.

The disclosed apparatus may include (1) a storage device that maintains information about mobile devices roaming within a wireless network, (2) an AP-prediction unit that (A) determines, based at least in part on the information maintained in the storage device, a number of times that a mobile device has visited a specific AP within the wireless network, (C) generates, based at least in part on the number of times, a score that represents a probability that the specific AP is the next AP visited by the mobile device, and then (D) determines that the score is above a certain threshold, and (3) a profile-distribution unit that provides, in response to the determination that the score is above the certain threshold, the specific AP with a roaming-session profile that facilitates transferring a roaming session of the mobile device to the specific AP. Various other apparatuses, systems, and methods are also disclosed.

The present disclosure proposes a handover management method and a base station having a smart antenna using the same method. A transceiver of the base station transmits and receives wireless data. An interface controller of the base station transmits a source beam-forming information and receives a target beam-forming information. A processing circuit of the base station is coupled to the transceiver circuit and the interface controller and is configured for transmitting the source beam-forming information when switching to a setting of the smart antenna corresponding to the source beam-forming information and receiving the target beam-forming information using the interface controller, recording the source beam-forming information and the target beam-forming information as a beam-forming pair to a history of a handover when performing the handover, grouping the beam-forming pair in the history into beam-forming pair groups, and determining handover parameters for each of the beam-forming pair groups respectively.
