Abstract: A method, system, and functional elements for transmitting cell management information in a cellular communication network, in which each cell comprises a base station communicating using at least one frequency and is defined by a radio coverage area of its base station, wherein a communication between a mobile station and a base station is based on a time frame structure comprising a plurality of time slots, in which transmitting time slots in the time frame structures of neighboring base stations, in which time slots cell management information relating to the respective cell is to be transmitted, are shifted against each other on a time basis. The transmitting of cell management information can be based on a predetermined transmission parameter, the value of which is representative of the radio coverage area of a base station.

Abstract: The idea of the present invention is to enable the transmission of control information via several logical channels and to select the transmission channel dynamically by using a predefined selection rule. There are at least two logical channels that can be selected for the transmission of information. These logical channels should preferably include at least one signalling channel which is allocated in a connection-specific manner. The signalling channels which are allocated in a connection-specific manner can be signalling channels which use the capacity of the traffic channel of independent singalling channels which are allocated separately from traffic channels. At least one of the logical channels available for selection should preferably also be a shared channel allocated to several connections for joint signalling.

Abstract: Active and inactive segmentation states are defined for transparent mode for a radio access network (RAN) interfacing with a core network (CN) and a user equipment (UE). If transparent mode is valid on the Iu-interface between the RAN and the CN, then an inactive segmentation state indicates to peer (UE/RAN) segmentation and reassembly (SAR) entities such as at the radio link control (RLC) layer that segmentation is blocked in the UTRAN, over the Uu-interface, and in the UE so that TTIs with periodicities greater than the minimum transmission interval may be utilized, except over said Iu-interface.

Abstract: A system and method for random access channel (RACH) capture, where user equipment (UE) transmits a series of time-spaced access preambles each having an increasing power level to Node B and terminates access preamble transmission in response to an acquisition indicator (AI) signal returned from Node B and transmits its RACH message part. A collision detection preamble (CDP) is sent immediately after the message or embedded with the message. A collision detection indicator (CDI) signal matching the CDP is transmitted from Node B to the UE identified as having the failed RACH message requesting retransmission of the message. Optionally, the relative retransmission power level is also specified to the UE along with the CDI signal.

Abstract: The invention relates to data transmission in telecommunication systems and particularly in radio systems. The invention employs “payload numbering” instead of or in addition to conventional frame numbering. Data (61) is split into fixed-length data blocks or payload units (62). The size of a block is preferably equal to or smaller than the shortest information field in frames (63) of the protocol(s) used. Each protocol frame carries one or more payload units. In an optimum situation the length of the information field in a protocol frame equals n * the length of the payload unit, where n is an integer. Instead of frame numbering (in some special cases possibly in addition to it) the protocol frame carries payload numbers both for indicating the payload units (data blocks) conveyed in the protocol frame and for acknowledging the received blocks.

Abstract: A wireless communications network has a plurality of terminals and at least one base station which transmits data to each one of said plurality of terminals on a wireless downlink and receives data from each one of said plurality of terminals on a wireless uplink. One of the terminals sends a rate request to the base station. The rate request requests that the data rate on the wireless uplink for the terminal be changed. In response to the rate request, the base station sends a rate grant to the terminal. The rate grant indicates whether or not the terminal may change the data rate on the wireless uplink.

Abstract: Data to be transmitted in a telecommunications system is arranged in frames (100). In order to process the data to be transmitted, a number of mutually optional actions is available. In order to indicate the actions employed in the processing of the data to be transmitted, the transmitting device includes in the frame to be transmitted a predetermined number of control bits (101), the value of said control bits indicating how the transmittable data contained in the frame is processed prior to transmission. In the arrangement according to the invention, there is formed (302) information as regards how many mutually optional actions there are available for processing the data to be transmitted, there is defined (302) the number of control bits contained in the frame, so that the number of actions indicated by the allowed control bit values is at least as high as the number of available, mutually optional actions, and there is included (307) in the frame to be transmitted a predetermined number of control bits.

Abstract: A method and associated equipment for use by a first entity (17) of a radio access network (101), such as a node B. in communicating with a UE (18) so as to control an uplink rate used by the UE (18) in communicating with the first entity (17), the method characterized by: a step in which the first entity (17) transmits to the UE (18) a rate control signal (RA) conveying information regarding the uplink rate. The rate control signal may be used to command the UE (18) to adjust the maximum uplink rate in a range or set of uplink rates; alternatively, it may be used to command the UE (18) to adjust the uplink rate. The rate control signal (RA) may be sent as a response to a rate change request signal (RR) received from the UE (18) by the first entity (17).

Abstract: A method and system for performing a pre-reserved handover in a mobile communciation system is suggested, wherein an additional handover preparation step is performed by determining at least one candidate base station in advance, to which handover is likely to be performed. An additional downlink connection to the at least one candidate base station is established before handover execution is performed. Thereby, proper handover can be ensured for cell environments in which a serving cell disappears very quickly from a mobile station.

Abstract: The invention relates to user equipment, which is adapted to use more than one access type for communicating with radio systems. After a service requiring a connection between the user equipment and the radio system has been activated, the suitability of the user equipment's current access type for the operation of the activated service is checked and access type re-selection is carried out, in response to the check, to select an access type suitable for the service.

Abstract: The invention relates to a method for transmitting packet switched data in a mobile communications system using an ARQ protocol. In the method the receiver requests, if necessary, retrasnmissions of the originally sent transmission unit, until the quality of the combined transmission unit formed of the originally sent transmission unit and its retransmitted copies corresponds to the predetermined quality level. The signal is not detected until after this. If the packet is interleaved and encoded and it is found out that the packet is not faultless, retransmissions of the transmission units of the packet that are of the poorer quality are requested. The invention also relates to a mobile communications system implementing the method of the invention.
