Methods and apparatus for managing paging in a wireless communication network
First Claim
1. A method in a network node of a wireless communications network, the wireless communications network further comprising a terminal device the terminal device being configurable in a plurality of radio resource control (RRC) states, the plurality of RRC states comprising a first RRC state in which the terminal device is configured with first paging occasions to listen for paging messages from the network node, the method comprising:
- configuring the terminal device with one or more second paging occasions for the terminal device to listen for paging messages from the network node, in addition to the first paging occasions, while the terminal device is in the first RRC state, responsive to one or more trigger events relating to a transition of the terminal device one of from the first RRC state to a second RRC state and from the second RRC state to the first RRC state, the configuring comprising one taken from the group consisting of broadcasting system information indicating the second paging occasions; and
transmitting to the terminal device a dedicated control message indicating the second paging occasions, the dedicated control message further relating to a transition one of from the first RRC state and to the first RRC state.

Abstract
There is disclosed a method in a network node of a wireless communications network, the wireless communications network further comprising a terminal device, wherein the terminal device is configurable in a plurality of radio resource control (RRC) states, the plurality of RRC states comprising a first RRC state in which the terminal device is configured with first paging occasions to listen for paging messages from the network node. The method comprises: configuring the terminal device with one or more second paging occasions for the terminal device to listen for paging messages from the network node, in addition to the first paging occasions, while the terminal device is in the first RRC state, responsive to one or more trigger events relating to a transition of the terminal device from the first RRC state or to the first RRC state. Additional methods and apparatus are also disclosed.
