20100091667 | Method and Arrangement in a Telecommunication System - The present invention relates to resource management in a telecommunication system. In particular the invention relates to detection and estimation of transport network load and optimization of transport network resources. According to the method and arrangement of the invention a serving node engaged in admission control identifies a transport network interface from which transport load measurements are required for the admission control, and a target radio network node related to the identified transport network interface. The serving radio network node configure the target radio network node to perform and report measurements on the transport network interface. | 04-15-2010 |

20100317351 | DETECTION OF COLLISIONS OF RADIO COVERAGE CELL IDENTIFIERS - Additional information is included in or used to generate a positioning reference signal to enable detection of a cell identifier “collision” between two different cells associated with two or more base stations. In one example embodiment, a user equipment terminal detects the collision using the additional information included in or used to generate positioning reference signals sent by two or more base stations and reports the collision to the network, and the network resolves the collision by assigning a different cell identifier to one of the colliding cells. | 12-16-2010 |

20120220305 | FACILITATING EFFICIENT MULTIMEDIA BROADCASE/MULTICAST SERVICE IN A TELECOMMUNICATION SYSTEM - A radio access network facilitates transmission of a Multimedia Broadcast/Multicast Service (MBMS) to user equipments in plural cells served by a radio base station. A radio network controller includes in a first message of a transport channel setup request either an indication that transport sharing is allowed or an identification of a common transport bearer. The radio base station configures a new transport channel mapped to the common transport bearer such that it is stable with respect to other common transport channels. During operation, the radio network controller provides the MBMS data over the common transport bearer and the radio base station retransmits the MBMS data over the common transport channels to the plural cells. If the MBMS data over the common transport bearer arrives outside of time-of-arrival windows of any common transport bearer, then the radio network controller adjusts the transmission accordingly. | 08-30-2012 |

20100273451 | Method and Apparatus for Mobile Terminal Positioning Operations - In one aspect of the invention presented herein, a mobile terminal requests positioning assistance data from its supporting wireless communication network, in response to receiving a positioning request from a positioning node. Further, in response to receiving the positioning assistance data from the network, the mobile terminal sends the positioning assistance data to the positioning node. In this manner, the positioning node advantageously gains access to network-generated positioning assistance data without need for requesting it from the network. In at least one embodiment, the mobile terminal receives the positioning request from the positioning node over a User Plane (UP) connection. However, the mobile terminal sends the positioning assistance data request to the base station over a Control Plane (CP) connection, and receives the requested positioning assistance data via the CP. The terminal transfers that data to the UP and sends it to the positioning node. | 10-28-2010 |

20120289284 | Cell Type Information Sharing Between Neighbor Base Stations - The present invention relates to a method and arrangement for cell type information sharing between neighbour base stations in a telecommunications system. One embodiment comprises informing a second radio base station serving a second cell and having a neighbour relation with a first cell served by a first base station, of at least the cell type of the first cell. This is accomplished by adding the cell type information to a set of information to be signaled to the second base station, and then signalling the set of information to the second base station. | 11-15-2012 |

A capacity enhancing cell is selectively switched on and off. When the capacity enhancing cell is shut down the cell does not exist over the air while cell configuration information is kept. When the capacity enhancing cell is switched on the cell becomes available again over the air interface. An indication of shut-down and a wake-up call message for switch-on of the capacity enhancing cell are communicated between a base station serving the capacity enhancing cell and a base station serving the basic cell. In this way energy savings can be supported without disrupting service availability. | 03-12-2015 |
