Abstract: Method and network entities for providing good performance for voice in multiRAB connection for services of a CS+PS call setup (31) without high throughput necessity but providing good throughput for the services needing it. A differentiation of the multiRAB configuration (bearer type, mobility parameters and channel switching timers), based on service detection, is performed either in the RAN either in the CN indicating eventually this detection to the RAN. If the detected service needs high bit rate/throughput (35), the RNC reconfigures the multiRAB configuration (37) so that a bearer type providing high throughput is allocated to said service and the RNC reassigns mobility and channel switching parameters to maximise this throughput and the radio resources. If the service does not require high throughput (34), the RNC configures a bearer type and parameters for mobility and channel switching as specified by the standards to provide good performance (36), low dropped call rate.

Abstract: The invention refers to a method for scheduling traffic in a communication channel of a mobile communications network which detects small sized data bursts and prioritizes their transmission. The detection is performed by comparison with two thresholds, one being an indicator of the instantaneous size of the data burst and the second one being related to the size of said data burst along a given period of time. The invention is also related to a network scheduler comprising means for carrying out the above method.

Abstract: A method for scheduling traffic in wide area cellular telephone networks supporting the High-Speed Downlink Packet Access. The traffic contains packets related to users that are buffered in priority queues according to a value (i) which indicates a priority for transmission assigned to an incoming packet. The method includes determining a delay td of the incoming packet. The method also includes calculating at a current scheduling time t at least one value of a scheduling priority SchedP(i,t) where scheduling priority SchedP(i,t) is a function of the value (i) indicating the priority of the incoming packet and the delay td of the incoming packet. The further includes scheduling the packets buffered in the priority queues according to the values of the scheduling priority SchedP(i,t), and repeating the method every transmission time interval.

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.

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: System and method for transmitting a radio signal in a mobile communication network. The radio signal has a circular polarisation.

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: 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: 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.
