Abstract: Base station apparatus (1) is provided for improving bandwidth usage in a cellular communication network serving at least one mobile terminal. The network is capable of supporting at least a first radio access technology (i.e. GSM) and a second radio access technology (LTE) and uses a predefined bandwidth range. The apparatus comprises a base band unit (3) including a counting means for determining the number of mobile terminals within a cell of the first radio access technology supporting the second radio access technology and a measuring means for determining the level of traffic carried by the first radio access technology cell; and a bandwidth assignment means for dynamically assigning a first portion of the bandwidth range to the first radio access technology and a second portion of the bandwidth range to the second radio access technology on the basis of the number of supportive mobile terminals and the level of first radio access technology traffic.

Abstract: The present invention discloses a method for selecting a transmission technology (MIMO or non MIMO) for a HSDPA connection established between a RNC and a UE depending on the mobility of said UE, measured at the RNC as variations of the position of the UE. Then, if the connection is established with HSDPA MIMO technology and the position variations exceed a first pre-defined threshold, the connection is switched to HSPDA non MIMO technology. Also, if the connection is established with HSPDA non MIMO technology and the position variations are below a second pre-defined threshold, the connection is switched to HSPDA MIMO technology.

Abstract: A method and network entity for downloading detected video packets. A minimum bit rate MinBR equals ViBR+M, where M?0 is a configurable bit rate margin from an estimated video bit rate ViBR. A specific bit rate SBR is greater than MinBR. The method uses MinBR and SBR as a minimum bit rate limit and a maximum bit rate limit respectively between which the bit rate for delivering video in case of congestion is defined. The method can further compare the predefined specific bit rate with a real throughput of the user requesting video download with a QoS profile, and if there is congestion and if the throughput is larger than or equal to SBR, the priority value of a QoS profile to be used for downloading video in case of congestion.

Abstract: A method for controlling receiver diversity operation in a base station of a mobile telecommunications network. The base station includes a first receiver arrangement and a second receiver arrangement. The method includes activating the first receiver arrangement, thereby receiving signals at a first gain level. The method also includes activating the second receiver arrangement, thereby receiving signals at a second gain level, the second gain level being equal to or lower than the first gain level. The method further includes measuring baseband consumption at the base station at predetermined intervals. The method finally includes, when the baseband consumption exceeds a predetermined deactivation threshold THDE, deactivating the first receiver arrangement, thereby leaving only the second receiver arrangement active.

Abstract: In RAN sharing scenarios wherein radio spectrum allocated to multiple mobile network operators is split into at least one carrier, the steps for switching the configurations of carriers for RAN sharing are proposed here, defining: a pooled configuration by which all the operators share at least one carrier; and a dedicated configuration by which each operator has at least one carrier assigned for allocation of its traffic. The start point for switching is single carrier in the pooled configuration. Traffic load in the shared single carrier is constantly measured to compare it with a threshold, so that, when the measured load exceeds the threshold and if spectrum pre-emption is possible to create additional carriers, the switching from the single carrier in the pooled configuration to the plurality of carriers is performed, selecting the configuration for each carrier from three possible options: pooled, dedicated or a combination of both.

Abstract: To determine which traffic and terminal types and in which parts of a call should be best served by a given carrier there is provided a method and system for dynamically allocating carriers in a MIMO network using S-CPICH. The consideration of which carrier to allocate addresses problems caused by the enablement of the diversity transmission technique. Carriers are dynamically allocated to terminals in a WCDMA network scenario taking into account each terminal's vulnerability to interference from a carrier using S-CPICH or STTD according to certain parameters, such as a requested service or the radio conditions at any given time. The carriers are allocated from carriers using P-CPICH, S-CPICH and/or STTD. The invention also relates to a system that implements this method in a WCDMA network.

Abstract: A method of selecting a cell from a certain active set of cells (102, 103) to become serving cell for a mobile terminal (101) instead of the primary cell (102) of said active set of cells (102, 103) during a call in a mobile communications network implementing soft handover, the method comprising the steps of: determining whether the radio access bearer (RAB) of said call is being served on a soft handover area or not, and: if said call is being served on a soft handover area, determining whether the user of said mobile terminal (101) can be considered static or in motion, and: if said user of said mobile terminal (101) is considered static, comparing the load of said primary cell (102) to the load of at least one of the remaining cells (103) within the active set (102, 103), and: if the load of said primary cell (102) exceeds the load of said at least one of said remaining cells (103) within the active set (102, 103) by a predetermined factor, transferring the downlink user plane from said primary cell (102)

Abstract: The described method provides a Network Controller (e.g., RNC) with an active set update procedure for application when activating STTD in the 3G networks. To avoid any call drop due to misalignments between the respective transmission diversity mode configurations of cells and the presence/absence of support for transmission diversity in user terminals, STTD mode is deactivated, in cases where the terminal is rejecting the Active Set Update message due to ‘invalid configuration’. The misalignments between the respective transmission diversity mode configurations may arise in a number of scenarios: handover from a cell with STTD deactivated to a cell with STTD activated, handover from a cell with STTD activated to a cell with STTD deactivated, or handover between cells with STTD activated. In all cases the solution consists of indicating to the UE the STTD Off configuration to obtain a success active set update procedure irrespective of the true configuration status.

Abstract: The invention relates to a cellular communication network serving mobile terminals or devices and how to reduce the signalling load in said network by introducing an auxiliary device which holds data packets in order to minimize connections according to a pre-determined rule.

Abstract: A system and method are described for detecting and controlling the phase difference introduced to radio signals by transmission branches of a transmission system in a mobile communication network. Periodically a calibration signal is generated at an input of the transmission branches during a phase calibration mode. The phase difference introduced by the two transmission branches is detected by detecting the phase difference between the calibration signal, which has at least partly passed through the first transmission branch and the calibration signal, which has at least partly passed through the second transmission branch. The phase difference between the radio signals is controlled based on the detected phase difference.

Abstract: Method and RNC for selecting transmission technology when a UE enters the network, which checks whether the UE is MIMO and, if so and only one carrier is available, allocates its traffic to said carrier and uses a S-CPICH to provide all MIMO traffic with a diversity pilot and Virtual Antenna Mapping for balance. If more than one carrier is available, the number of UEs, their radio conditions and load of carriers are checked periodically. If the carrier is busy only with MIMO and its load is higher than the load of the remaining carriers, diversity CPICH of STTD is selected; otherwise and only if the UEs vulnerable to STTD with good radio conditions exceed a certain number, the S-CPICH is selected. The RNC can reconfigure the network from transmitting MIMO traffic with STTD to using MIMO with S-CPICH or vice versa dynamically by periodical check of the load and UEs criteria for configuration change.
