摘要:
A channel inverse multiplexer/multiplexer (IMUX/MUX) (14a) of a MAC sublayer (14) of a UTRAN RNC (11) for providing to a UE (18) traffic (communication signals including in general both control and user data) at a higher rate than the UE can accept over a single channel. The channel IMUX/MUX performs inverse multiplexing of traffic for downlink, and multiplexing of traffic on uplink, and does so in a way that is transparent to all other layers/entities of the UTRAN (11 17) and to the UE (18).

The area of the invention belongs to the transport technologies in UTRAN. This invention concerns a method for multiplexing a data stream onto a transport bearer between an originating network node and a receiving network node in a telecommunications network. This is done in order to ensure the effective usage of transport resources over the two interfaces, i.e. Iub/Iur. To accomplish this the RNC and/or Node B/RNC should check if the there already exists a transport bearer, which can be utilized for HS-DSCH transport over Iub/Iur interface. Because of this a transport bearer identification code or transport bearer id is needed to identify this bearer between RNC and Node B/RNC.

摘要:
RNCs are assigned different bit length identifiers, for example 12 bits (legacy) and 16 bits (extended). To enable handovers between adjacent RNCs with different bit length identifiers, several solutions are presented. In a first solution, no logical/direct connection is configured between the adjacent RNCs having different bit length identifiers at least for the case where the value of the longer identifier is not compatible with the shorter identifier. In a second solution, some RNCs are given both a long and a short identifier, and use the one matching the length of the RNC with which a handover occurs. In a third solution, for all adjacent RNCs with an Iur logical connection between them but still having different bit length identifiers, the most significant bits of the longer identifier are not the same as the whole of the shorter bit length identifier. Multiple variations and examples are presented, and implementations include method, apparatus, embodied computer program, and integrated circuit.
摘要:
A method for communication systems configured to provide wireless data communications for users is disclosed. The disclosed method includes communicating information with a node of a radio access part of the communication system. The information includes a first set of quality of service information and a second set of quality of service information. The second set of quality of service information is indicative of the nature of the information of the first set of quality of service information.

A method, a system and a network element for performing a handover of a mobile equipment from a source network to a target network in a mobile telecommunication system, wherein data, which may be transferred via the source network to the mobile equipment when it is linked to the source network, are going to be buffered in a network element in case a need for a handover arises, and the data buffered in the network element are forwarded from the network element to the target network for transferring them to the mobile equipment after it has been linked to the target network.
摘要:
A method, apparatus and system of network congestion notification is disclosed. A source node sends a destination node a data packet. Upon receipt of the data packet if network congestion is detected, the destination node introduces a congestion indication into a data packet. The data packet, including the congestion indication, is sent to the source node.

The invention is directed to a method for controlling delays in a cellular telecommunications network. The delay control method according to the invention is based on a hierarchical structure of delay controlling entities, which preferably communicate only with entities directly above or below them in the hierarchy. In the downlink direction, an entity receiving data, such as a base station or a splitting unit, sends a timing report to the entity sending the data if the data is received too early or too late, whereafter the sending entity may adjust the sending time of data. The same reporting and adjusting process may be repeated through all levels of the control hierarchy, resulting in a collective control of delays from the top of the hierarchy, for example from a RNC, to the bottom, for example to a base station. In the uplink direction, a higher level entity receiving data from a lower level entity may command the lower level entity to adjust the sending time, if the data is received too early or too late. When the same action is repeated in all levels of the hierarchy, a collective control of delays is achieved for the link between the lowest level, e.g. the base station, and the highest level, e.g. a RNC.
摘要:
A method carries out statistical multiplexing in a telecommunications network comprising a transmitting unit for transferring channels containing information from at least two traffic sources, a receiving unit and a transmission link between them. The information to be transmitted in the telecommunication system is transferred over the transmission link in transmission frames. The method is characterized by assembling a variable-length transmission frame comprising an allocation field and an information field, identifying an active channel, allocating an information field transmission block from the transmission frame to the active channel's information to be transferred, inserting the information to be transferred into the allocated transmission block, adding the channel allocation information into the allocation field of the transmission frame in which the channel's information is for the first time continuously transferred, maintaining the channel's allocation for as long as the channel is continuously active, and transmitting the transmission frame to the receiving unit.
