MANAGING BEHAVIOR OF RELEASE-7 AND RELEASE-8 USER EQUIPMENT DURING CONTINUOUS PACKET CONNECTIVITY CONFIGURATION

摘要

When a serving Node B has deactivated Continuous Packet Connectivity and the UE then is reconfigured with a RRC reconfiguration message, it can happen that the UE acts as though CPC is activated whereas the serving Node B, on the other hand, acts as though CPC functionality is still deactivated. In several embodiments of techniques for addressing this problem, previously known signaling messages and/or user plane frame headers are modified to include new indicators/parameters, which are used to signal that a given UE should be expected to have non-uniform behavior with respect to remembering CPC activation status after acting on a RRC Reconfiguration message, because it is a Release 7 or Release 8 mobile station. These new indicators/parameters may also be used by a Node B, in some embodiments, to acknowledge the receipt of an indication from an RNC that non-uniform behavior should be anticipated for a given UE.
