摘要:
Method and controller device for controlling a plurality of N transport paths in RANs, wherein a primary path is assigned for each type of traffic to allocate voice or data calls, comprising: measuring load of the primary path periodically, when a call is incoming, comparing the measured load with a threshold, if the load of the primary path is less than or equal to the threshold, allocating the call to the primary path otherwise: calculating the available bandwidth of each transport path; comparing the available bandwidth of the primary path to the available bandwidths of the other transport paths and: if the available bandwidth of the primary path is greater than or equal to the available bandwidths of the others, allocating this call to the primary path; otherwise, allocating the call to a secondary path chosen from the remaining N−1 transport paths.

A method for data transmission in a wide area mobile network supporting both MIMO User Equipments and non MIMO User Equipments includes allocating in a first signal the traffic of non MIMO user Equipments, a first MIMO data stream and a primary pilot channel, allocating in a second signal a second MIMO data stream and a secondary pilot channel, and transmitting the first signal and the second signal with two orthogonal circular polarizations.

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.

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.

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.

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.In this way, the bandwidth assigned to GSM and LTE can be configured to take account of changes in the traffic levels and device capabilities in either RAT.

摘要:
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.
