20110019629 | Selecting a Transmission Technology - 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 | 01-27-2011 |

20110077019 | Dynamically Allocating Carriers - 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. | 03-31-2011 |

20110085614 | Selecting Transmission Technology for Communications in Wide Area Mobile Networks - 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. | 04-14-2011 |

One innovation of a method includes measuring at least one parameter related to a radio-communication between a user device (UD) and the telecommunication network (TN) and determining, based on the at least one measured parameter, whether the network is congested or overloaded. | 07-23-2015 |
20150208277 | CONGESTION MANAGEMENT - Apparatus and methods for congestion management by a user device (UD) in a telecommunication network (TN) are disclosed. One innovation of a method includes identifying, by the user device (UD), a congestion condition in at least one cell on the telecommunication network (TN). The method further includes determining, by the user device (UD), at least one appropriate action to be taken by the user device in order to minimise said congestion condition in the at least one cell and performing, by the user device (UD), the determined at least one appropriate action. | 07-23-2015 |
