INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING APPARATUS, AND COMPUTER READABLE RECORDING MEDIUM
An information processing system includes: a first server associated with a first region, the first server including a first processor configured to output information concerning a predetermined service to a vehicle traveling in the first region; and the vehicle including a second processor, wherein the first processor is configured to perform handover processing for outputting information concerning the vehicle held by the first server to a second server associated with a second region adjacent to the first region when the vehicle moves from the first region to the second region in a case where the vehicle has moved to an outside of the first region and to an outside of an extended region obtained by extending the first region.
CONTROL DEVICE AND METHOD THEREFOR
A control apparatus (151) selects a target core network entity for providing a mobility management service or a data transfer service to a radio terminal (111), from among a plurality of candidate core network entities (121, 141, 142) having different route costs to the radio terminal (111) or having different sizes of a management range, based on at least one of: a delay tolerance level of the radio terminal (111); a frequency of occurrence of control signaling of the radio terminal (111); and a communication interval of the radio terminal (111). This contributes, for example, to determining which of a plurality of core network entities is used for a radio terminal by using one or more criteria (indices or parameters) other than the mobility of the radio terminal.
Gateway relocation control method and control device in mobile communication system
A control method and device, as well as a system, are provided that make it possible to perform relocation at an appropriate timing without impairing a user's sensory feeling about use of a service. A relocation control device 301 that controls relocation of a packet network gateway 100a which provides functionality as an anchor for ensuring mobility of a mobile terminal in a mobile communication system, includes a bearer information acquisition section 311 that, when an occasion for relocation arises, acquires information to obtain importance and a use state of a communication between a mobile terminal 50 and the packet network gateway 100a, and a relocation determination section 312 that determines whether or not to perform relocation, based on the importance and the use state of the communication.
Systems and methods for mobility aware multiaccess edge computing device selection and relocation
A user equipment may determine a latency requirement of the user equipment, and may determine a first set of latencies between the user equipment and a first multi-access edge computing (MEC) device. The user equipment may determine a second set of latencies between the user equipment and a second MEC device, and may calculate a first violation probability based on the latency requirement and the first set of latencies. The user equipment may calculate a second violation probability based on the latency requirement and the second set of latencies, and may identify the first MEC device or the second MEC device based on the first violation probability and the second violation probability. The user equipment may selectively initiate a MEC handoff of the user equipment to the first MEC device or the second MEC device based on identifying the first MEC device or the second MEC device.
Enodeb reference signal reduction
In embodiments, apparatuses, methods, and storage media may be described for reducing the overhead associated with the transmission of channel training signals from an eNodeB (eNB) of a wireless network. Specifically, the eNB may receive feedback from a user equipment (UE) regarding the received signal energy of a first and second beamformed signal produced with a first and second beamforming vector, respectively. The eNB may identify, based on the feedback of the received signal energy, a signal subspace and a null subspace. The eNB may then transmit a channel training signal to the signal subspace.
Method and apparatus for multi-RAT access mode operation
A method and apparatus for multiple radio access technology (multi-RAT) access mode operation for a wireless transmit/receive unit (WTRU) are disclosed. A WTRU and a network may enable a multi-RAT access mode of operation based on at least one of WTRU subscription, a service agreement of the WTRU, a roaming status of the WTRU, a selected access point name (APN), an Internet protocol (IP) flow class, a subscriber profile identity for the WTRU, requested quality of service, or a proximity indication indicating proximity to a cell supporting multi-RAT access mode. The WTRU may send a capability indication of support of multi-RAT access to a network, wherein the multi-RAT access mode is enabled based on the capability indication. A partial handover of bearers may be performed. In performing the handover, the target cell is determined based on a priority rule.
ROUTING OF MPTCP SUBFLOWS
A method performed in a source gateway which is logically positioned in a first wireless access network between a radio device and a first mobility anchor. The source gateway comprises a Multipath Transmission Control Protocol (MPTCP) proxy for a TCP flow between the radio device and a peer. The TCP flow comprises at least two subflows between the radio device and the source gateway. The subflows comprises a first subflow over the first wireless access network and a second subflow over a second wireless access network. The method comprises receiving uplink data of the second subflow from a second gateway logically positioned in the second wireless access network between the radio device and a second mobility anchor, and sending downlink data of the second subflow to said second gateway. The method also comprises moving the proxy from the source gateway to a target gateway logically positioned in the first wireless access network between the radio device and the first mobility anchor, as part of a handover of the radio device within the first wireless access network. The method also comprises, after having moved the proxy to the target gateway, forwarding downlink data of both the first and second subflows to the target gateway, and forwarding the received uplink data of the second subflow to the target gateway.
Wireless local area network (WLAN) traffic load measurement provisioning to wireless cellular networks
Generally, this disclosure provides devices, systems and methods for provisioning of wireless local area network (WLAN) traffic load measurements to third generation partnership project 3GPP wireless cellular networks. A WLAN element manager (EM) may include a polling module to poll a WLAN access point (AP), the polling to request traffic load data from the WLAN AP; a timer module to trigger the polling module to poll at periodic intervals; a logging module to receive and log the requested traffic load data; and an integration reference point (IRP) agent including a reporting module to generate a traffic load report for transmission to a network manager (NM), the traffic load report based on the logged traffic load data.
Captive portal state detection and avoidance for multiple-interface traffic offloading
In one embodiment, a mobile device connecting to a Wi-Fi hotspot first performs a connectivity check to determine whether the wireless connection is trapped in the walled garden of a captive portal by transmitting a connectivity check message to one or more external endpoints in the public IP network. If no response is received, the mobile device determines that it is in the captive portal state, and generates a browser window bound to the Wi-Fi state tracker of the mobile device displaying the portal page for the captive portal. In such a manner, the mobile device does not offload any traffic from its wireless cellular interface to its Wi-Fi interface until it is certain the Wi-Fi interface may access the public IP network, thereby preventing data interruption for mobile applications.
TERMINAL DEVICE, BASE STATION DEVICE, MME, AND COMMUNICATION CONTROL METHOD
An MME detects that a PDN connection is not effective and changes from a non-optimal gateway to a bearer established in a PDN connection using a more optimal gateway as an endpoint node. This configuration allows an already-established PDN connection to switch to a new PDN connection using the more optimal gateway, which achieves optimal communication control for continuing communication of UE.
