  • Patent number: 9686741
    Abstract: A method, apparatus and computer program product are therefore in order to enable efficient management of multiple communication channels. In this regard, the method, apparatus, and computer program product may utilize a user equipment (UE) (208), such as a mobile terminal, to communicate a plurality of networks. The UE (208) may identify that multiple communication networks are available or in use, and notify a network node (204, 206) associated with one of the networks of the communication status. In response to receiving a notification that UE (208) is communicating across an alternate channel, the network node (204, 206) may reconfigure the channel with which the network node (204, 206) communicates with the UE (208), or instruct the UE (208) to do the same.

  • Patent number: 9578579
    Abstract: A method, apparatus and software related product (e.g., a computer readable memory) for efficient measurement reporting by UEs to provide, for example, lower UE power consumption, efficient use of network resources, small cell ottloading, etc., in wireless networks such as LTE/LTE-A systems that can be also applied in inter-system cases such as a mix of UTRAN and E-UTRAN as one non-limiting example is presented. The UE performs measurements and event evaluation as in conventional LTE/LTE-A systems, but for certain cells/carriers an event triggered measurement report, which conventionally would be transmitted when time-to-trigger (TTT) expires (see details e.g. in 3GPP TS 36.331), is not transmitted but regarded as buffered (e.g., in a memory or buffered memory of the UE) as a candidate measurement report, when a predefined criterion is not met. This predefined criterion is e.g. a need at the UE to request network resources for uplink transmission by the UE.

  • Publication number: 20170048733
    Abstract: Various communication systems may benefit from well-defined measurement requirements. For example, measurements for multi-broadcast single-frequency networks (MBSFNs) may benefit from definition of minimum measurement requirements related to, for example, reference signal received power (RSRP) and reference signal received quality (RSRQ). A method may include obtaining MBMS configuration parameters. The method may also include defining generic minimum MBSFN measurement performance requirements, based on the MBMS configuration parameters.
