  • Patent number: 9794980
    Abstract: Disclosed is a method that includes receiving, when in a radio resource control (RRC) Connected state, a RRC connection release message from a network access node; setting a wait timer in accordance with a wait timer indication that comprises part of the RRC connection release message; and upon an expiration of the wait timer, enabling the initiating of sending an RRC connection request message to the network access node. Also disclosed is a method that includes operating a network access node with mobile node and sending a RRC connection release message to the mobile node. The RRC connection release message comprises a wait timer indication for specifying an amount of time that the mobile node should wait before initiating the sending of a RRC connection request message.

  • Publication number: 20170164281
    Abstract: A method of carrying out dual connectivity with a secondary access node and an apparatus is provided. A mode of operation of a user equipment is determined in dependence on the presence of bearers mapped to the secondary access node. Operating in a first mode occurs when it is determined that one or more bearers are mapped to a secondary access node. Operation in a second mode occurs when it is determined that no bearers are mapped to the secondary no access node. The second mode comprises limiting a listening time to a downlink channel from the secondary access node with respect to the first mode.

  • Publication number: 20160330648
    Abstract: A method and apparatus may be configured to receive at least one set of barring parameters from a network entity. Each set corresponds to a barring check and has a unique implicit or explicit priority. Each set of received barring parameters also corresponds to at least one application that is allowed to bypass the barring check associated with the corresponding and lower priority sets of barring parameters. An application belonging to one of the application groups corresponding to a set of barring parameters needs to pass all the barring checks according to the higher priority barring parameters to access the network. The method can also include determining whether an application bypasses the barring check associated with the corresponding and lower priority sets of barring parameters.
