Sami Kekki has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: The fundamental idea in the invention is as follows. Instead of setting up and releasing a bearer, e.g. an AAL2 connection, the connection is maintained and only modified to have either a zero bandwidth or the required bandwidth. The zero bandwidth corresponds to a release in the conventional case and the required bandwidth corresponds to the setup of the connection. The invention is especially applicable in the cases where it is reasonable to assume that a connection once established and currently/no longer needed, that usually can be an AAL2 connection, will be needed again after a reasonably short period of time. However, the invention is applicable also in the general case where the AAL2 connections are initially set up with zero or small resources and then modified afterwards to an appropriate bandwidth on demand.
Abstract: 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).

Abstract: The present invention relates to a method for controlling access to a private base station. An identifier indicating an operation area previously accessed or detected by a communications device requesting communication with a private base station is received. The access to the private base station is controlled on the basis of the identifier.
Abstract: The invention proposes a method and system for transmitting information in a network. The network includes at least one buffer unit for buffering the information to be transmitted. The buffer unit includes one or more first and second buffer stages. The information to be transmitted is buffered in one of the first buffer stages and then transferred to the second buffer stage from which it is transmitted to another network element. The first buffer stage is adapted to receive control data from the second buffer stage which control data influences the transferring of subsequent information from the first to the second buffer stage. Thereby, the necessary maximum buffer capacity of the second buffer stage can be kept small without danger of data loss caused by overflow. Moreover, the transmission delay caused by the second buffer stage can be reduced.
Abstract: The present invention relates to a method, tunnel protocol layer, and network device for securing a data packet on a network link. A security layer is provided in the tunneling protocol layer of the wireless network, and a secured data packet is generated by adding to the data packet a header in accordance with said security layer of the tunneling protocol. The secured data packet is then transmitted over the link by using a link layer connection.

Abstract: 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.

Abstract: 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.
Abstract: Described is a method of providing an AAL2 end-to-end connection in an ATM transmission network using a first and a second AAL2 endpoint and at least an AAL2 switch, wherein a plurality of AAL2 paths is at least present between the first AAL2 endpoint and the at least one AAL2 switch or between the at least one AAL2 switch and the second AAL2 endpoint. The method comprises the step of establishing an end-to-end connection on a concatenation of a first path between the first AAL2 endpoint and the at least one AAL2 switch with a second path between the at least one AAL2 switch and the second AAL2 endpoint. The use of the first and second path is assigned for traffic of the first AAL2 endpoint which acts as an originating node. The selection of the first and second path is performed by using a mapping scheme which is valid at least between the first AAL2 endpoint and the at least one AAL2 switch and between the at least one AAL2 switch and the second AAL2 endpoint.
Abstract: A telecommunication arrangement for transporting power control information, comprising a base station, a radio network controller for controlling the base station, and where information between the base station and the radio network controller is transmitted on transport channels carried by transport bearers, each having a one-to-one relationship to a transport channel, a user equipment communicating with the base station, the base station comprises means for mapping data received from the user equipment onto transport channels. The mapping means is configured to map power control information from a transport channel onto a different transport bearer than the bearer with which the transport channel has the one-to-one relationship.
Abstract: 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.
Abstract: 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.
Abstract: The invention concerns a method for boosting data transmission in a telecommunications system and a mobile communications system. The invention is characterised in that the telecommunications network uses at least on a part of the transmission path between the fixed station, e.g. a base transceiver station, and the transcoder unit speech coding at a lower transmission rate than the transmission rate of the speech coding used on the transmission path between the fixed station and the terminal equipment. The speech parameters received from the terminal equipment are converted for the speech coding method used on the transmission connection between the fixed station and the transcoder unit and vice versa. In the network transcoder unit it is possible to reconvert speech parameters received from the direction of the terminal equipment e.g. into speech parameters of the speech coding used on the transmission path between the terminal equipment and the fixed station.
Abstract: There is disclosed a method of transporting data in a dedicated channel of a mobile communication system, comprising selectively including data in the payload of a frame, and further including in said frame an indication of at least one of the selectively included data and excluded data. The dedicated channel is an enhanced dedicated channel, and wherein the data are data sets or transport blocks.
Abstract: The area of the invention belongs to the transport technologies in UTRAN. There are two transport technologies in use in the transport networks (domains) and the Network Elements in these two different domains need to be able communicate with each other. The baseline for the invention is that the existing ATM/AAL2 network and its 3GPP specifications should be left untouched as much as possible. In UTRAN based on ATM/AAL2 transport there is AAL2 Signalling used as ALCAP. the invention is based on the idea that the existing ALCAP, e.g. Q.2630 is used not only in the ATM/AAL2 domain as an ALCAP, i.e. no changes to the existing specifications, but also as an auxiliary control protocol in the IP transport domain. This is accomplished by using a user defined information element of said existing ALCAP.
Abstract: There is disclosed a method of determining a frame transmission interval for a channel between a network access point and a network access controller, the method comprising the steps of: determining a frame transmission interval value at the network access controller; transmitting the determined frame transmission interval value from the network access controller to the network access point; receiving the frame transmission interval value at the network access point.
Abstract: 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.

Abstract: A wireless telecommunications system comprises a radio network layer for carrying mobile-specific signaling, and a transport layer for establishing user channels between system nodes over a transport network. The transport network is visible to the radio network layer only via a primitive interface through which it can request transport services. The invisibility of the transport network to the radio network layer makes the radio network layer independent of the underlying transport network and enables the use of different transport network technologies. The radio network layer signaling procedures and connections are mapped with the underlying transport layer signaling procedures and connections by using binding information at one end of the connection leg, which is exchanged between the network and transport layers through a primitive interface, and used to “identify” the radio network layer and the transport layer connection setup signaling carried out between the nodes.
