ENHANCED CONNECTION MANAGEMENT FOR MULTIPLE ACCESS NETWORKS

摘要

Semi-connected state operation for UEs in multiple-access networks is described. In the semi-connected state, UEs may monitor system information and paging, and mobility may be UE-controlled. Base stations may determine whether to transition UEs from the connected state to the semi-connected state based on capabilities, priority, data connections, or loading conditions. Base stations may maintain context information and logical traffic connections for UEs while UEs continue to be served by the base station in the semi-connected state. Thus, when a transition from the semi-connected state to the connected state occurs, the base station does not have to re-establish security parameters, nor re-establish logical traffic connections within the network for carrying control plane and user plane data for the UE. Context information for semi-connected state UEs may be shared between neighboring base stations or base stations within a context area. The techniques may be applied to LTE/LTE-A networks.

1. A method for wireless communication at a base station, comprising:
determining, for a user equipment (UE) served by the base station and configured in a connected state with the base station, that the UE is to be transitioned out of the connected state; indicating to the UE that the UE should transition out of the connected state; and maintaining a context for the UE at the base station subsequent to the indicating that the UE should transition out of the connected state and while the UE continues to be served by the base station.
