  • Publication number: 20220159547
    Abstract: The present disclosure provides a method, performed in a wireless device, for enabling controlled communication of non-real time data while the wireless device is registered with a radio network node for communicating real-time data. The method comprises receiving a network data indicator indicative of one or more suitable data transfer occasions to communicate the non-real time data over the radio network node. The method comprises determining based on the network data indicator whether any non-real time data is to be communicated in the one or more data transfer occasions. The method comprises, upon determining that non-real time data is to be communicated, communicating non-real time data over the radio network node to an external node at the one or more data transfer occasions.

  • Publication number: 20220141740
    Abstract: A wireless communication network (102) can employ techniques for the network (102) to indicate specific radio access characteristics to be used by a user equipment (100) 5 when responding to a paging message. The network (102) can indicate a specific radio access technology (RAT) that the UE (100) should use when connecting to the network (102). In this manner, the UE (100) can initiate a connection using the desired RAT rather than first initiating a connection with an incorrect RAT and performing a handover or network reconfiguration.
