Abstract
The present disclosure relates generally to the field of wireless communications, and in particular to techniques for efficiently transferring, among network nodes, an access context required to initiate data transfer when a user equipment (UE) is in an active or suspended Radio Access Network (RAN) connection state. The techniques disclosed herein involve identifying, based on UE-specific data (such, for example, as mobility information, a traffic profile), one or more relevant network nodes where the UE in the suspended RAN connection state could be located at the time when next data transfer needs to be initiated. After that, the access context is sent from an anchor network node to said one or more relevant network nodes. By sending the access context in this manner, network signalling overhead and storage capacity overhead may be significantly reduced.
