The invention relates to a wireless access telecommunications system comprising at least one SA-cell and a plurality of LA-cells. A method for a terminal to facilitate selection of an LA-cell to camp on when in an idle mode is disclosed. The method includes steps of, while the terminal is in an active mode having a wireless connection with the SA-cell, the terminal obtaining, via the wireless connection with the SA-cell, a set of configuration parameters of one or more LA-cells of the plurality of the LA-cells that are relevant for the SA-cell and selecting, out of the one or more LA-cells, one LA-cell to camp on, where the selection is performed based on the received set of the configuration parameters. In this manner, the terminal may select a suitable LA-cell to camp on in a manner that is quick and energy-efficient.

The invention relates to a communication system comprising a first wireless access station with a first data connection for transferring user data and a second wireless access station with a second data connection for transferring user data. The first wireless access station and second wireless access station are located at distant positions from each other. The first wireless access station comprises one or more antennas for wirelessly transmitting user data, that are received over the first data connection, to a user terminal. The second wireless access station is configured to receive user data over the second data connection and to transmit the user data directly to the first wireless access station for transmission to the user terminal. The communication system further comprises a controller configured for controlling at least a part of the user data for the user terminal to flow over the second data connection.

The disclosure relates to a method for data packet transmission from a network node of a telecommunications network. The method involves transmitting, from the network node, a plurality of data packets onto a first communications path of the telecommunications network, the plurality of data packets comprising a first data packet. At least one network coded data packet is obtained at the network node, wherein the at least one network coded data packet is obtained from network coding of two or more data packets and wherein at least one data packet of the two or more data packets corresponds to the first data packet transmitted onto the first communications path. The obtained at least one network coded data packet is transmitted from the network node onto a second communications path of the telecommunications network.

The invention relates a method and system for assessing coverage of a wireless access network within a desired area via cooperating wireless access networks and terminals capable of measurement and reporting across the different wireless access networks. The cooperation refers to, among other things, the ability of obtaining coverage assessment for one of the wireless access networks using results of the measurements collected at one of the other wireless access networks. In this manner, more accurate and complete coverage assessment may be obtained, relative to the prior art approaches.
摘要:
For two mobile communication devices registered with two different communication networks proximity between the devices is determined based on information indicative of geographic location of the mobile communication devices. The proximity is checked on the fulfillment of the condition of being below a predefined threshold. The information regarding the geographic location of each of the mobile communication devices is stored in a distributed database accommodated at the mobile communication devices.
摘要:
A first mobile communication device (102) is communicatively connected to a first communication network for receiving a first communication service in a first geographic area (106) and in a first frequency-band. A second mobile communication device (108) is communicatively connected to a second communication network (110), different from the first network, for receiving a second communication service in a second geographic area (112) and in a second frequency-band. The first device is transmitting, in a third frequency-band that is disjoint from the first and second frequency-bands, a first identifier of the first device and a first location of the first device. The second network is monitoring the third frequency-band and receives the information in the transmission. Under control of the first identifier, a database is consulted for determining if the first communication device is listed as associated with the second communication device. If so, a second location of the second device is determined and a spatial proximity is determined between the first device and the second device based on the first location and the second location. The spatial proximity information enables the first communication device and the second communication device to set up a device-to-device communication session.

The invention relates to a system and method for updating a neighbour cell list of a wireless access node. User terminals to be to be transferred from a first wireless access node of a first wireless access network to a second wireless access node of a second wireless access network are detected. From the first wireless access node, one or more of the detected user terminals are requested to report cell information of a plurality of wireless access nodes of at least one of the first wireless access network and the second wireless access network. The cell information is received from the one or more of the detected user terminals and at least one of the first neighbour cell list and the second neighbour cell list is updated using the received cell information.

摘要:
The invention relates to a method for activating at least one inactive cell in a wireless telecommunications infrastructure. The telecommunications infrastructure comprises an active cell containing a plurality of terminals. A presence signal is transmitted in the at least one inactive cell. The plurality of terminals in the active cell detect the presence signal(s) of the one or more inactive cells to gather information from the inactive cell. The information is reported to and received at the telecommunications infrastructure. The information received from the plurality of terminals is processed in a processing system of the telecommunications infrastructure to provide a processing result. The inactive cell is activated when the processing result fulfils at least one activation condition such that at least one of the plurality of terminals is within a coverage area of the activated cell.
