摘要： A system and method enable wireless user equipment (UE) to undergo a serving radio network subsystem (SRNS) relocation to a radio network controller (RNC) that does not support a fast dormancy feature while maintaining synchronization with the packet-switched domain of the core network. The UE is made aware of whether the target RNC supports the fast dormancy feature by way of an indication provided to the UE in a reconfiguration message provided by the source RNC, that is, the RNC to which the UE was connected prior to the SRNS relocation. In this way, the UE can behave accordingly whether or not the target RNC supports the fast dormancy feature.

摘要： Systems and methodologies are described herein that facilitate synchronization of Node B-ordered parameters, such as discontinuous transmission (DTX)/discontinuous reception (DRX) status, following a handover failure and/or other suitable triggering events. As described herein, upon failure of a handover from a source Node B to a target Node B, a mobile device can return to the source Node B and synchronize with the source Node B with respect to DTX/DRX status and/or other Node B-ordered parameters. DTX/DRX synchronization can be performed by setting DTX/DRX status to a default state, a last DTX/DRX state utilized prior to initiation of the failed handover, or the like. Identification of the last DTX/DRX state can be conducted as described herein according to an analysis of respective orders communicated by the source Node B in relation to respective time intervals following initiation of the failed handover.

摘要： Methods and apparatuses are provided for synchronizing security parameters between access terminals and a wireless network. An access terminal and network entity can conduct a security mode procedure where the access terminal sends a security mode complete message to the network entity. On receipt of the security mode complete message, the network entity may update to new security parameters. The access terminal may initiate a mobility procedure while the security mode procedure is ongoing and may, as a result, abort the security mode procedure and revert back to the old security parameters. The access terminal can send a mobility update message to the network entity including a dedicated status indicator adapted to inform the network entity that the access terminal has reverted back to the old security parameters. In response to the mobility update message, the network entity may revert back to the old security parameters.

摘要： A method for determining an extension type of a system information block segment is described. A system information block segment of type extension is received in a system frame number. A byte in a system information block extension type lookup table corresponding to the system frame number of the system information block segment is calculated. A bit position in the system information block extension type lookup table corresponding to the system frame number is calculated. The extension type expected at the system frame number for the system information block segment is determined using the byte and the bit position.

摘要： In a particular embodiment, a method includes sending a message from a communication device to a radio network controller. The message indicates that a data session has ended. The data session is supported by a wireless channel between the communication device and the radio network controller. After a time period following the sending of the message, a second message is selectively sent to the radio network controller. The second message indicates that the data session has ended. The second message is selectively sent based at least in part on whether a measurement indicates that data was communicated via the wireless channel during the time period.
