  • Publication number: 20190320382
    Abstract: A radio device receives an access information table from the cellular network. The access information table comprises parameters of a plurality of configurations for controlling access of the radio device to the cellular network. Further, the radio device receives an identifier from the cellular network. Depending on the identifier, the radio device selects one of the configurations from the access information table. In response to determining that at least one of the received access information table and the received identifier is outdated, the radio device determines, depending on an indicator associated with the selected configuration, whether to perform an access attempt to the cellular network on the basis of the selected configuration.

  • Publication number: 20190306764
    Abstract: A method for avoiding unnecessary actions in a connection establishment comprises sending a request to a network node to initiate the connection establishment, upon sending the request to the network node, starting a timer for the connection establishment, wherein an expiration of the timer stops the connection establishment for a user equipment (UE), and stopping the timer to stop the connection establishment upon the UE receiving a suspend message or a release message, or upon the UE performing a cell reselection procedure while the timer is running. The timer may prevent the UE from waiting the connection establishment to be completed if there is an error or bad transmission in the connection establishment. Furthermore, the timer to stop the connection establishment may avoid unnecessary actions and inform other layers in the network when the timer expires to stop the connection establishment.

  • Publication number: 20190306910
    Abstract: New Radio (NR) RRC includes an RRC_INACTIVE state, which introduces ambiguities in the network's knowledge of UE behavior. A mechanism is introduced for handling parameters received when a UE enters RRC_INACTIVE upon the UE attempting to resume an RRC connection and, as a response, receiving a Release or Suspend message. The timer associated to the mobilityControlInfo (equivalent to T320) is stopped and associated parameters discarded upon receiving RRC Release or Suspend. Information received in a Release or Suspend message is discarded upon receiving RRC Release or RRC Suspend.

  • Patent number: 10425951
    Abstract: Method performed by a first network node, connected to a second network node serving a wireless device in a first cell. The first cell has a second cell as neighbor. Each cell has a first beamforming configuration for a first use corresponding to a first beam gain, and a second configuration for a second use corresponding to a second gain. The first network node obtains, for each cell, a first indication of the second gain in relation to the first. The first network node also determines, based on the first indication, a first value to be applied in a cell selection procedure between the first and the second cell. The first network node initiates sending the second indication of the first value, or a third indication of the first indication.

  • Patent number: 10390291
    Abstract: A radio device (10) acquires system information from the wireless communication network. The system information comprises parameters for controlling access of the radio device (10) to the wireless communication network. The system information is organized in at least two classes differing with respect to a risk level associated with accessing the wireless communication network based on one or more parameters of the class. Further, the radio device (10) receives validation information which enables the radio device (10) to determine, individually for at least one of the classes, validity of the system information as previously acquired by the radio device (10). Depending on the validity and the risk level associated with at least one of the classes, the radio device (10) determines whether to access the wireless communication network based on the system information as previously acquired by the radio device (10).

  • Publication number: 20190239182
    Abstract: A method and a first network node (200) of a wireless network, for handling paging of a wireless device. A Radio Access Network Area, RANA, which is supported by the first network node (200), is registered (2:1) in a database (202) by network nodes IN supporting the RANA, including the first network node (200). The network nodes (204) that support the RANA are then identified (2:3) in the database (202). When it is detected (2:2) that a wireless device (D1) needs to be paged in the RANA, e.g. for receiving data, a paging message is distributed (2:4) to the identified set of network nodes (204) as an instruction to perform radio transmission of the paging message. Further, which is available to the network nodes throughout the wireless network. Thereby, any network node in the wireless network, such as the first network node (200), is able to perform distribution of a paging message to all network nodes that support a particular RANA, as registered in the database (202).
