摘要:
A method for processing signals in a communications system comprising a first station and a plurality of second stations, said method comprising the steps of receiving at said plurality of second stations signals from said first station; sending said received signals to a designated one of said plurality of second stations; and processing in said designated second station the signals received by plurality of second stations to provide a single signal.

Methods and systems for setting-up channels in third generation (3G) communication systems that utilize wideband, code division multiple access signaling protocols including the reserving of a branch of the channelisation code tree to set-up the channels. By reserving a branch of the tree, the channels can be automatically coded using the pre-reserved codes in the branch which eliminates the need for separate verification procedure to be performed to determine whether there are enough transport layer resources available to accommodate the new channel and whether the new channel will disturb or otherwise interfere with current channel data transport. Since the new channels are set-up using reserved codes, the transport layer resources already exist to accommodate the new channels and there can be no chance of existing channel interference.

The present invention describes a method, system and an interconnecting handler for sending connection-oriented or connectionless data between two endpoints in a protocol architecture. The transport protocol in the protocol architecture is in a preferred embodiment the Stream Control Transmission Protocol (SCTP). The present invention allows the setup and release of a connection when using a simplified protocol stack which is able to provide the same kind of services without using peer-to-peer messages like SCCP or SUA use. The present invention also enables discrimination between connection-oriented and connectionless services without peer-to-peer signalling.
摘要:
A communication system covering an area, including a plurality of first units. Each of the first units being configured to control the allocation of channels in a part of the area. At least one of the first units being configured to send information relating to channel allocation in the part of the area associated with the at least one first unit to at least one other of the first units. The at least one other of the first means units being configured to take into account the received information when controlling the allocation of channels in the part of the area associated with the at least one other first units.

The invention relates to a method of ciphering data transmission in a radio system, and to a user equipment using the method, and to a radio network subsystem using the method. The method includes the steps of: (602) generating a ciphering key; (604A) producing a ciphering mask in a ciphering algorithm using the ciphering key as an input parameter; (604B) using a logical channel specific parameter or a transport channel specific parameter as an additional input parameter to the ciphering algorithm; and (606) producing ciphered data by applying the ciphering mask to plain data.
摘要:
The present invention relates to a method and arrangement for performing a cell update procedure in a cellular communications system. The cellular communication system comprises a plurality of cells, and a first and a second network controllers. A station is initially on a first cell controlled by the first controller and then in a second cell controlled by the second controller. When changing from one cell to another the station sends cell update information and other information to the second controller which then stores the received other information and send to the first controller a message indicating that information has been received at the second controller from the station. A network element for use in the above method is also disclosed.
摘要:
A method of transmitting from a first node to a second node, said method comprising the steps of transmitting in a first mode at least one data frame from said first node to said second node; and determining if there is no data to be transmitted and if there is no data to be transmitted transmitting at least one empty frame in the first mode; and switching to a second mode in which no transmission is made in the absence of data to be transmitted at least some of the time.
摘要:
A mechanism for synchronizing transmission of frames in a telecommunications network including a mobile station, a radio network controller, at least one base station. The mobile station and each base station have a corresponding timing reference. The mechanism includes or performs the steps of establishing a connection-specific timing reference which is common to all nodes involved in the connection; determining, for the base stations an offset between the timing reference of the base station in question and the CFN; and using the offset in the base stations, to compensate for the difference between the timing references.
摘要:
A frame control method and apparatus is described for controlling a transport frame used for transmitting a data unit via a dedicated channel between network elements of a communication system having different types of connections. The frame type coding of the transport frame is selected in accordance with a connection type of the dedicated channel, such that a connection type specific frame length, dimension and/or segmentation is achieved. This allows an efficient usage of transmission resources, wherein an overhead of control information for the transmission of the data units is achieved.
