  • Carrier aggregation means that the user equipment UE can use multiple component carriers simultaneously. These multiple component carriers may be located under the same access network node, such that the number of accessible carriers under the same access network node is increased.

  • Paging area When the UE ends the attach procedure, the UE returns to the idle state. In the idle state, the UE may change the paging area, and at intervals, the UE will update the paging area.
  • the core network When the core network is looking for a UE, the core network first checks the paging area to which the UE belongs, and then sends a paging message to all access network nodes in the paging area, and then the next access network node goes down to the next. All cells send paging messages.
  • the inventors have found that:
  • the access network node Since the UE may be camped on any carrier under the access network node when the UE is idle, when the paging message is sent to the access network node, the access network node needs to page to all the component carriers under it.
  • the introduction of carrier aggregation technology requires the access node to send paging messages to more carriers, which leads to an increase in paging signaling overhead.
  • the UE if the UE can receive control information on multiple component carriers, the UE needs to maintain multiple sets of signaling bearers of multiple component carriers, which will also result in an increase in control signaling overhead. Summary of the invention
