| 20100284267 | CALL SET-UP IN A COMMUNICATION NETWORK - A call set-up method is described for use in a communication network, in particular a third generation mobile communication network. First, it is attempted to set-up a call between a call originator and a call destination using a communication connection of a first type, for example Voice over IP. In case that it is determined that the call cannot be set-up using the communication connection of the first type, a node in the communication network sets up the call to both the call originator and the call destination using a communication connection of a second type, for example Circuit Switched Adaptive Multi Rate voice call. | 11-11-2010 |

| 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 |
| 20110069693 | Multicarrier Transmit Diversity in UTRAN for HSPA - Multicarrier transmit diversity in UTRAN for HSPA, comprising a baseband unit and a remote radio unit of a Node B configured for receiving a data stream from an RNC and subsequently generating N encoded data streams and corresponding RF output signals for downlink transmission over N antennas; wherein the remote radio unit transmits the N (preferably two) RF output signals using transmission diversity over different carrier frequencies. The remote radio unit can transmit each STTD encoded data stream over different frequency carriers or transmit one STTD encoded data stream over a frequency carrier at frequency f | 03-24-2011 |

| 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 |
| 20110086620 | PROVIDING BROADCAST CONTENT TO A MOBILE TERMINAL - A method and cellular communication network are described for providing broadcast content to a mobile terminal. A broadcast content network hub located in a network element of the radio access network of the cellular communication network receives the broadcast content from a broadcast content source external to the cellular communication network. It provides the broadcast content to the mobile terminal over a user connection. | 04-14-2011 |
| 20110122962 | PHASE DIFFERENCE IN A MOBILE COMMUNICATION NETWORK - 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. | 05-26-2011 |
