摘要： A method is proposed for determining the round-trip delay for sending multimedia data, such as voice or video data, between a first network node and a second network node over a communications network, where data is encapsulated in data units comprising at least one frame of encoded data. The method includes the steps of: said first network node sending a request for reconfiguration of the data unit structure to the second node; the first node detecting a reconfiguration response from the second node, where the reconfiguration response comprises at least one data unit of data having a structure that corresponds to the request for reconfiguration. The first node then measures the time elapsed between sending the reconfiguration request and detecting the reconfiguration response and determines a value for roundtrip delay using said measured time. In accordance with a first embodiment, the request for reconfiguration is a request to change the encoding mode of the multimedia data. A node adapted to measure this round-trip delay is also proposed.

摘要： A base station detects the transition of a mobile station from a DTX mode to a continuous transmission mode. The base station schedules an uplink transmission by the mobile station during an uplink transmission period while the mobile station is in DTX mode and receives an uplink LLC PDU from said mobile station during the scheduled uplink transmission periods. The base station determines the operating mode of the mobile station based on the size of the received uplink LLC PDU.

摘要： A method and a communication station (5) for determining a packet format of a data packet based on at least one compressed header information field. A header packet format of a data packet is determined based on the determined packet format of a partially or completely compressed header information part. The station may also determine a codec rate (10) based on the result of a previously performed compression of at least one header information field. In one embodiment, internal cross-layer signaling from a header generator module (6) to a payload generator module (7) in the communication station is used for signaling information associated with determining the header packet format of the data packet. The method reduces bandwidth fluctuations associated with services such as text messaging, audio, or audiovisual services; lowers the delay variations and the erasure rates for application media streams; and provides for faster set-up of sessions.

摘要： The present invention relates to a method for scheduling a data transmission to a user equipment in a communication system comprising at least one radio network controller (RNC) governing a number of base stations, wherein the communication system supports data transmission from a base station to an user equipment on a high speed packet access (HSPA) bearer or a dedicated channel (DHC) or on similar bearers in a CDMA2000 system. The method comprises the steps of: identifying at least one predetermined scheduling condition for data transmissions for the user equipment; determining at least one current scheduling conditions of the user equipment; comparing the predetermined scheduling conditions of the user equipment with the current conditions of the user equipment; selecting a bearer for the data transmissions during a session from a base station based on the comparison; and using the selected data bearer during the data transmission session or until a new data bearer has been selected. Furthermore, the invention relates to a user equipment, a radio network controller, a computer readable medium and mobile communication system for data transmissions such as VoIP service transmissions in wireless communications systems

摘要： The proposed technology relates to methods and radio network nodes for Explicit Congestion Notification, ECN, marking of user traffic in wireless communication networks. For example, a method performed by a sending radio network node (10) comprises the step of monitoring (S10) a congestion metric on a data radio bearer, and the step of transmitting (S20) control information indicating traffic congestion on the same data radio bearer, based on the monitored congestion metric, to a receiving radio network node (20).Further, a method performed by a receiving radio network node (20) comprises the step of receiving (S100) control information indicating traffic congestion on a data radio bearer, based on a congestion metric, from a sending radio network node (10), and the step of marking (S200) next ECN-capable user packet of the user traffic on the same data radio bearer with ECN marking, based on the received control information.

摘要： A flow management method comprises receiving (210) of incoming downlink packets. The received downlink packets are classified (220) in sub-flows, based on information that is available in a header of respective such received downlink packet. The downlink packets of each sub-flow are queued (230) in a respective sub-flow queue. Downlink packets are extracted (250) from the sub-flow queues into a common outgoing flow. A sub-flow queue from which no downlink packets yet have been extracted is prioritized (240). The extraction comprises assigning of an indicator of last service occasion to each sub-flow queue when a predetermined amount of data has been extracted from said sub-flow queue. When no prioritized sub-flow queues are present, the sub-flow queue with the earliest last service is selected. When a prioritized sub-flow queue is present, the prioritized subflow queue is selected. The downlink packets of the common outgoing flow are sent (260).
