20130121167 | CONTROLLING COMMUNICATIONS IN A MULTI-CARRIER WIRELESS COMMUNICATION SYSTEM - A method of controlling communication between a first network node and a second network node in a multi-carrier wireless communications system, network nodes and a computer program product are disclosed. The method of controlling communication between a first network node and a second network node in a multicarrier wireless communications system in which a predetermined set of a plurality of carriers are utilised to support communication between the first network node and the second network node, the predetermined set of the plurality of carriers comprising a primary carrier and at least one secondary carrier, comprises the steps of: determining an occurrence of an event requiring a change in the primary carrier; indicating to a third network node that a physical layer instruction is to be transmitted between said first network node and the second network node; and transmitting a physical layer instruction between the first network node and the second network node, the physical layer instruction encoding reselection information to cause the second network node to select a different carrier from the plurality of carriers as a new primary carrier. By sending the instruction using the layer one or physical layer, the speed at which the instruction can be transmitted between the network nodes is vastly increased, which enables fast switching to occur, thereby preventing a loss of communications between the network nodes. By indicating to a third network node that a physical layer instruction is to be transmitted between the first network node and the second network node, maintenance of synchronisation is simplified and unpredictable network behaviour is minimised. | 05-16-2013 |

20140057628 | AUTOMATIC NEIGHBOUR RELATION - A mobile device operable to perform automatic neighbour relation functions in a wireless telecommunications network, a radio network controller, methods and a computer program product are disclosed. The mobile device is operable to perform automatic neighbour relation functions in a wireless telecommunications network in which neighbour relations derived by the mobile device are provided to a network node of the wireless telecommunications network and comprises: measurement logic operable, in an automatic neighbour relation mode, to measure characteristics of a neighbouring cell; and determination logic operable to determine, from the characteristics and from an indication of previously provided neighbour relations, whether a neighbour relation based on the characteristics has been provided previously to the network node and, if not, to generate a new neighbour relation to be provided to the network node. Hence, only neighbour relations which are not indicated as having been provided previously need be generated. Accordingly, no neighbour relation may be generated when an indication is provided that that neighbour relation has already been provided. This avoids transmitting redundant information, which reduces traffic in the network and reduces the unnecessary use of resources to transmit and process such duplicated information. This reduces the load in the network and in the mobile device. Furthermore, the power consumption of the mobile device may be reduced as a consequence. | 02-27-2014 |

20150043442 | CONFIGURING TRANSMISSIONS - A method of configuring transmissions over a radio bearer between a base station and user equipment of a wireless telecommunication network, a base station, user equipment, a radio network controller and computer program products are disclosed. The method of configuring transmissions over a radio bearer between a base station and user equipment of a wireless telecommunication network comprises the steps of: preconfiguring the user equipment to support transmissions over a plurality of transport channels of the radio bearer, the plurality of transport channels being associated with a communication state of the user equipment, each of the plurality of transport channels being mappable with logical channels of the radio bearer, the logical channels providing information to be transmitted by the transport channels; and remapping the logical channels onto a different one of the plurality of transport channels in response to a message transmitted between the base station and the user equipment, the message indicating the different one of the plurality of transport channels to be used to support the transmissions between the base station and the user equipment. This approach enables the user equipment or base station to select a transport channel to carry the information from the logical channels autonomously of other network nodes within the network, such as, for example, the radio network controller. By avoiding the need to involve other network nodes in the reselection of the transport channel, rapid changes in the transport channel can be made based on knowledge of the current conditions within either the base station or the user equipment. This approach enables fast switching of the transport channel to improve the performance of the network. | 02-12-2015 |
