摘要:
Disclosed is a wireless communication system and a user equipment (UE) providing wireless communication services, and more particularly, a method of controlling data flow in an Evolved Universal Mobile Telecommunications System (E-UMTS), a Long Term Evolution (LTE) system, and a LTE-Advanced (LTE-A) system that have evolved from a Universal Mobile Telecommunications System (UMTS). In particular, the present invention provides an effective way of controlling data flow of a relay node (RN) in the LTE-A system.
摘要:
Approaches are provided for a congestion detection algorithm for detection of congestion in outroute port queues (associated with respective satellite downlink beams), of a Layer 2 switch on-board a processing satellite, before the congestion reaches the point of dropping packets. Such approaches employ congestion notification protocols to inform all inroute sources of the congested ports. The on-board Layer 2 switch sends congestion notifications to the on-board system controller. The system controller broadcasts a notification reflecting the report of contested ports/beams to source terminals. The source terminals then segregate bandwidth requests regarding traffic destined for congested beams from traffic destined to all uncongested beams, and categorize such requests based on respective traffic priority levels. The system controller makes bandwidth grants according to congestion (for example allowing only higher priority traffic on congested beams) to alleviate the congestion conditions of the respective ports/beams.
摘要:
Methods for LTE-WLAN interworking control and management are proposed. In one novel aspect, a mobile termination (MT) can use an AT command to report radio access network (RAN) assistance parameters of the current serving cell. A terminal equipment (TE) can use the AT command to query the specific RAN assistance parameters and the threshold value provided by the network for making LTE-WLAN interworking decisions. If reporting is enabled by TE, then an unsolicited result code (URC) is sent from MT to TE whenever changes in the current RAN assistance parameters occur.

摘要:
A method of signalling in a wireless communication system (300) comprising a first network element (310) serving a wireless communication unit (325) with at least one packet data network (PDN) connection. The method comprises transmitting, by the first network element (310) to the wireless communication unit (325), a signalling message relating to a wireless communication unit (325) uplink (UL) PDN transmission, where the signalling message comprises a parameter indicative of at least one aggregate maximum bit rate (AMBR) value.

Provided are a communication system, a communication device, a communication method, and a recording medium which enable data to be communicated more efficiently according to the change of the degree of link congestion. This communication device performs data communication with another communication device via a wireless base station, and is provided with: a wireless information collection means for collecting wireless information relating to wireless communication of the other communication device; a congestion degree assessment means for assessing a congestion degree of a wireless link from the collected wireless information; and a schedule determination means for determining the schedule of the data communication with the other communication device on the basis of the assessed congestion degree.
摘要:
A radio network controller, RNC, connected to a first exchange and a second exchange which manage a same location registration area. The RNC includes a manager (24) configured to manage a mobile station under control of the radio network controller, in association with the first exchange or the second exchange; a transfer (26) configured to transfer a signal transmitted from the mobile station to the first exchange or the second exchange which is associated with the mobile station; and a monitor (25) configured to monitor state of the first exchange and the second exchange. The transfer (26) is configured to transfer a signal from the mobile station associated with the first exchange, to the second exchange, when the monitor (25) detects inaccessibility to the first exchange.

The present invention relates to control of downlink data in a packet based telecommunications network and in particular to UE control of downlink data. This is provided in devices and methods for handling such control, for instance a user equipment (101), UE, in a telecommunications network (100). The UE has an associated Internet Protocol, IP, address. The UE comprise at least one processing unit (201), at least one computer readable storage unit (202), at least one communications interface (203), and wherein the processing unit is arranged to execute instructions sets stored in the storage unit for determining that only some downlink data is to be received on the communication interface and sending a message using the communication interface to an infrastructure node (103, 104) indicating that downlink data is to be filtered depending on type of service when transferred to the UE.

Provided are a method, system, device for controlling congestion or overload and an eNB. The method includes that: one or more eNBs configured to detect congestion or overload of user plane data are selected, and the one or more eNBs selected are notified; the one or more eNBs selected detect a congestion or overload event of the user plane data; when a triggering condition is met, the one or more eNBs selected send congestion or overload indication information to a GCS AS; and the GCS AS determines a start or end of congestion or overload which occurs in an MBMS area according to the congestion or overload indication information reported by the one or more eNBs selected, and correspondingly selects a manner in which trunking service data are sent. By the technical solutions of the disclosure, the problem of influence for a trunking service when congestion or overload occurs in a network may be solved.

Flow control can be performed for every piece of end-to-end traffic. A transmission device includes a reception buffer which temporarily accumulates received transmission unit data, a signal generation section configured to generate a control signal for instructing to stop transmission of transmission unit data by designating another transmission device serving as an end point of a transmission side for traffic of the transmission unit data to be received by its own device as a transmission destination when an amount of accumulation in the reception buffer has exceeded a predetermined upper-limit threshold value, and a transmission section configured to transmit the control signal.
