  • Publication number: 20140106695
    Abstract: The specification and drawings present a new method, apparatus and software related product for antenna clustering for multi-antenna aperture selection (MAAS), e.g., in LTE wireless systems, using multi-core DSP processing with sub-optimum selection of N out of M of antenna signals and minimizing the performance degradation due to the sub-optimal antenna/antenna signal selection. Assigning each DSP core (machine) to N/K antennas (i.e., to antenna signals) having a similar property (e.g., polarization) and a same tier, the selection of N out of M using a predefined criterion (e.g., best SINR) is reduced to selecting N/K out of M/K which reduces the computation complexity by a factor of K, where K is a number of the DSP cores.

  • Publication number: 20140095675
    Abstract: A network node receiving a preference for a power optimized configuration for a user equipment (UE) can in response change the UE's minimization of drive test (MDT) configuration to conserve UE power. For example, this change can be from immediate reporting of MDT measurements to connected mode logging MDT measurements or no reporting of MDT measurements; or to a longer interval for reporting them, or to drop the reporting of available location information with MDT measurements. Other teachings have actions by the UE, autonomous of the network, to conserve power. A UE receiving a MDT configuration having an MDT measurement reporting or logging interval, and also one or both of a discontinuous reception or paging configuration having a DRX/paging interval can adapt the MDT configuration autonomously of the network to conserve its battery power.

  • Patent number: 8688551
    Abstract: There is proposed a charging control in which a policy and charging control function provides first (preliminary) charging control information, such as PCC rules, when the communication connection is set up or modified. Then, service information can be retrieved leading to an updated set of charging control information. The policy and charging control function provides then the updated charging control information for enforcement, wherein the charging system is informed about both the preliminary nature of the first charging control information and the validity of the second charging control information for a time before the update, i.e. before the transmission of the second charging control information. The charging system can use this updated charging control information and knows that it has to replace the former charging control information, so that the charging procedure can be corrected accordingly.

  • Publication number: 20140086049
    Abstract: A capacity allocation method comprises receiving (303), in a network apparatus (101), a capacity request message regarding a user terminal (102). In response to receiving the capacity request message, the apparatus (101) checks (303) one or more service parameters related to the user terminal (102). If the checking (303) reveals that enhanced network service activation criteria are fulfilled, the service parameters are used to define (303), by using a suitable network algorithm, a temporarily enhanced network service for the user terminal (102) such that the temporarily enhanced network service exceeds the service level originally agreed for the user terminal (102).
