  • Patent number: 10498502
    Abstract: This disclosure relates a method and a base station for network sharing using carrier aggregation. The base station of a multi-carrier system comprises a multiple of cells, where each cell corresponds to a carrier that is associated with a PLMN. The base station receives (302, S-424, S-516, S-616) a UE request with information of a UE (402, 502, 602), where a first cell of said multiple of cells corresponds to a first carrier. The base station determines (304, S-428, S-520, S-626) based on base station settings and/or UE information, whether an other carrier associated with a different PLMN is available to said UE. If so, the base station sends (306, S-430, S-440, S-524, S-530) a resource configuration message destined for said UE (402, 502, 602), enabling said UE to configure said other carrier as a SCC. Better coverage, peak rates and capacity, without suffering from the drawbacks of existing RAN sharing techniques, are provided.

  • Patent number: 10412666
    Abstract: A network entity receives a WLAN access message from a UE. The WLAN access message includes an indication of the UE status with the telecommunication network. The network entity detects the indication of UE status and determines from the indication whether to allow the UE access to the WLAN. When the WLAN is integrated with the telecommunications network, the network entity sends a query to the telecommunication network (e.g. the RAN or core network part) for a decision based on the UE status with the telecommunication network. The indication may include data representative of RAN or core network accessibility information (e.g., limited service or no coverage), WLAN access only, a user preference for accessing the WLAN instead of the telecommunication network, and/or any other connectivity or preference information for use by the WLAN or network entity in determining whether to allow UE to access WLAN.
