Abstract

Official abstract text for this publication.

In order to re-establish a suspended RRC connection, the mobile device ( 101 ) in one example sends a connection re-establishment request message to the RAN ( 102 ) to have the suspended RRC connection re-established. The RAN node may need to attempt to retrieve the RRC connection data (either from memory or if from another network element if stored elsewhere/if the RRC connection was suspended by another RAN node) and verifies whether the RRC connection is valid. When verified, the mobile device ( 101 ) receives, in response to the message, a connection re-establishment command message from the RAN ( 102 ). In response to the message, the mobile device ( 101 ) re-establishes the RRC connection with the RAN ( 102 ), using the stored RRC connection information, and sends a connection re-establishment complete message to the RAN ( 102 ). The mobile device ( 101 ) and RAN ( 102 ) may then resume user plane data communication with each other.

First claim

Opening claim text (preview).

What is claimed is: 1. A method, implemented in a node of a Radio Access Network (RAN) for use with a mobile device, the method comprising: receiving at the RAN node a request from the mobile device for re-establishment of a radio resource control (RRC) connection that was deliberately suspended by another RAN node, wherein the another RAN node is configured to transmit a connection suspend command message to the mobile device to cause the mobile device to suspend the RRC connecti…
