  • Publication number: 20150099488
    Abstract: A system includes a first access network arranged to operate according to a first Radio Access Technology, a second access network arranged to operate according to a second Radio Access Technology, and a user device which is connectable to the first access network and to the second access network. The system also includes an authentication node arranged to identify the user device, when seeking access to the second access network, through a user device identifier for the user device, wherein the user device identifier is associated with the first access network. A query node provides information about a context of the user device in the first access network based on the user device identifier. An access selection node generates an access selection decision for the access sought by the user device to the second access network based on the provided context, and the access selection decision is then executed.

  • Patent number: 8938212
    Abstract: Methods, apparatus, and systems for measuring, on a per-QoS-class basis, the average number of user devices active on the uplink of a wireless communication system are disclosed. In an exemplary method, a number of mobile terminals with buffered data for transmission to a base station is estimated based on received buffer status reports. An estimated quantity of active mobile terminals is calculated, based on the received buffer status reports and a number of mobile terminals for which a semi-persistent scheduling grant has been granted. In some embodiments, the estimated quantity of active mobile terminals is estimated on a per-traffic-class basis, in which case the technique includes calculating first and second estimated quantities, corresponding to mobile terminals having active data bearers for first and second traffic classes, respectively, based on the received buffer status reports and the number of mobile terminals for which a semi-persistent scheduling grant has been granted.

  • Publication number: 20140247807
    Abstract: A user equipment, UE, (20) determines a mobility state of a Wi-Fi access point, AP, as one of a moving mobility state and a non-moving mobility state along with control information relating to UE cell (re-)selection and/or handover behavior based on the determined mobility state of the Wi-Fi access point, AP. The UE then controls its cell (re-)selection and/or handover behavior in relation to the Wi-Fi access point, AP based on the determined control information. In a preferred embodiment, the UE can communicate with a cellular base station, BS, and with the Wi-Fi access point, AP. The UE detects the Wi-Fi AP, determines that the Wi-Fi AP is moving based on a moving AP indication, and controls cell (re-Selection and/or handover behavior of the UE based on the determination that the Wi-Fi AP is moving along with other information.

  • Patent number: 8706130
    Abstract: Methods and apparatus relate to cellular communications and in particular to a frequency spectrum shared by two cellular networks. An object is flexible utilization of the spectrum. This is achieved by a method where a first of the networks occupies part of the shared spectrum in relation to the traffic load in the first network. The first network informs a second of the networks on the extent the shared spectrum is occupied, for the second network to be free to use the shared spectrum outside the occupied part. A radio resource management unit, a base station controller, and a radio base station are also disclosed. An advantage is that spectrum can be lent from an old system when a new system is introduced.

  • Patent number: 8594074
    Abstract: A wireless terminal (30) is capable of communicating with a first network (22-1) and a second network (22-1, 22-3), the first network (22-1) being an LTE network. A wireless terminal method comprises (prior to making a request to participate in a circuit switched call with the second network) the wireless terminal (30) camping on a respective selected cell (of each of the first network and the second network and thereby having tuned to both the selected cell for the first network and the selected cell for the second network. In view of already camping on the selected cell of the second network, the wireless terminal (30) does not make a measurement with respect to a cell of the second network in a time period between the making of the request to participate in the circuit switch call and actual establishment of the circuit switched call with the second network.

  • Patent number: 8537688
    Abstract: The invention discloses a method (1100) for a cellular wireless access TDD system (100) with a base stations (120, 220) for respective cells (110, 210) in the system, where each cell can accommodate at least a first user terminal (130, 230). The user terminals can receive traffic from their base stations during a down link period, and can transmit traffic to their base stations (120, 220) during an up link period (UL). There is a first guard period (TDu) at the transition from down link to up link, and a second guard period (TUD) at the transition from up link to down link. The method comprises measuring the interference level in a second plurality (110, 210) of cells during part of the time between two consecutive down link periods, and varying the duration of said first and/or second guard period in said second plurality of cells (110, 210) according to the interference level.

  • Patent number: 8477653
    Abstract: The performance of a network, such as a mobile communications network, having multiple network nodes can be monitored. In a first network node, certain data flows passing through the node are tagged by adding a performance management identifier. In a second network node, statistics relating to data flows containing the performance management identifier are aggregated, and the aggregated statistics are reported to a management node of the communications network. This allows for the gathering of accurate statistics relating to specific types of data flow, such as data flows to specific types of user equipment or containing specific types of data, even though the second node, in which the statistics are generated, cannot itself distinguish between the different data flows.

  • Patent number: 8412160
    Abstract: The technology described relates to management of data packets and buffers comprising segments of data packets in a mobile communication system. Information associated with data packet segments is analyzed by a Base Station System (BSS) housing a data buffer. Based on this information analysis, the BSS can identify those segments in the buffer that constitute a complete data packet. Once identified, the segments can be discarded from the buffer. The information can include size information, whereby the analysis comprises pairwise comparing the size of a current segment with the size of a next consecutive segment. This size comparison enables identification of a first segment and a last segment of the complete data packet. The information could also, or alternatively, include a notification provided in the header of the segment. This notification identifies the associated segment as the first or last segment of the data packet or an intermediate segment.

  • Patent number: 8229365
    Abstract: A method for use in a cellular system comprising a plurality of base stations with corresponding cells, in which system the communication between users in a cell and the base station is divided into an up link period and a down link period, the method comprising letting a controlling node instruct the base stations regarding: a first point in time when the base station should start transmitting a control signal; a second point in time when the base station should start to listen for control signals from other base stations and measure their time of arrival and signal strength; a third point in time when the base station should cease listening for control signal; and a fourth point in time when the base station should transmit the measurements results to a receiving node in the system.
