摘要： Systems and methodologies are described that facilitate security activation within a specified security activation time. Thus, where handover occurs or is initiated within the activation time, security keys can be activated in such a way as to not be substantially affected by the handover. In one example, a handover time can be set to occur beyond the security activation time to ensure the security activation happens first. Additionally, a handover command can comprise security keys that can be activated upon handover in another example. Moreover, in non-real-time contexts, dummy packets can be transmitted to allow timer operability with packet sequence numbering, or security activation times can be substantially ignored by utilizing a verification process.

摘要： Techniques for performing in-order data delivery during handover in a wireless communication system are described. A user equipment (UE) may perform handover from a source base station to a target base station. The target base station may start a timer after a data path from a gateway to the UE has been switched from the source base station to the target base station. The target base station may receive forwarded packets for the UE from the source base station and may receive new packets for the UE from the gateway. The target base station may send the forwarded packets received prior to expiration of the timer to the UE before any new packets. The target base station may send the forwarded packets to the UE without waiting for the timer to expire and may send the new packets to the UE after the timer expires.

摘要： Systems and methodologies are described that facilitate identifying a plurality of keysets utilized in a communications network. The keysets can include ciphering keys that provide data encryption and decryption and integrity keys that provide data integrity protection. A key identifier can be included in a packet data convergence protocol header that indicates a keyset employed in connection with data in a protocol data unit. In addition, a route indicator can be provided in a radio link control header that distinguishes a source cell and a target cell in networks configured without RLC reset.

摘要： Techniques for sending data during handover with Layer (2) tunneling are described. In one design, a user equipment (UE) sends first Layer (2) packets to a source base station prior to handover to a target base station. The UE sends at least one second Layer (2) packet to the target base station, which identifies the second Layer (2) packet(s) as being intended for the source base station and thus forwards the second Layer (2) packet(s) to the source base station via a Layer (2) tunnel. The UE sends third Layer (2) packets to the target base station after the handover. The target base station processes the third Layer (2) packets to obtain IP packets and sends the IP packets to a serving gateway after a trigger condition, which may be defined to achieve in-order delivery of IP packets from the source and target base stations to the serving gateway.
摘要翻译：描述了利用层（2）隧道在切换期间发送数据的技术。在一种设计中，用户设备（UE）在切换到目标基站之前向源基站发送第一层（2）分组。 UE向目标基站发送至少一个第二层（2）分组，目标基站将第二层（2）分组标识为用于源基站，并因此转发第二层（2）分组）通过层（2）隧道到源基站。在切换之后，UE向目标基站发送第三层（2）分组。目标基站处理第三层（2）分组以获得IP分组，并且在触发条件之后将IP分组发送到服务网关，其可以被定义为实现来自源和目标基站的IP分组的按顺序传送到服务网关。

摘要： Systems and methodologies are described that facilitate providing flow control feedback for controlling downlink data transmission rates. Various schemes can be utilized to send the flow control feedback from an access terminal to a base station. For example, a control PDU (e.g., MAC control PDU, PDCP control PDU) can be generated based upon a level of resource utilization of the access terminal, and sent to the base station for controlling the downlink data transmission rate. Following this example, a type of control PDU, a value included within the control PDU, etc . can be selected as a function of the level of resource utilization. By way of another illustration, a CQI report that includes a value selected as a function of the level of resource utilization associated with the access terminal can be generated and transmitted to the base station for controlling the downlink data transmission rate.

摘要： An apparatus, method, processor(s), and computer program product avoids user data loss by network-controlled, user equipment assisted handover in a wireless data packet communication system. A wireless receiver receives radio link control (RLC) packet data units (PDUs) from user equipment (UE) being served by a source node. A wireless transmitter commands the UE to handover. A network communication interface transmits RLC Uplink (UL) context from the source node to the target node, and transmits RLC Downlink (DL) initialization message and buffered in-transit DL RLC PDUs from the source node to the target node.

摘要： Methods, systems and apparatus for dispersing a group of user equipment (UEs) concentrated on a single channel is disclosed. After receiving a disperse command the UEs select a channel, and then select a cell. The channel selection may be performed using a random or pseudorandom function. The cell selection may be performed prior to camping on the cell. Prior to camping the UEs may test the acceptability of a candidate cell and/or may perform a cell reselection. The result of the dispersion is that the UEs are distributed amongst many channels (a, b, c, and d), where reference are found in Figures 1A and 1B.

摘要： Systems and methodologies are described that facilitate multiple-phase selective connection establishment in wireless communications networks. Radio resource control (RRC) layer communications can be instantiated between a mobile device and base station. Additional information can be required by a downstream network component regarding the mobile device. Accordingly, the RRC resources can be utilized to transmit the additional information from the mobile device to the network component to facilitate the multiple-phase establishment. This can be accomplished using non-access stratum (NAS) messages. Further, the information can relate to authorization, security re-configuration, context re-synchronization, an identity of the mobile device, and the like.

摘要： Systems and methodologies are described that facilitate notifying and detecting system information block (SIB) modification in subsequent modification periods. Access points can advertise information in a current SIB indicating a subsequent modification period in which the SIB will be modified. Devices can receive the SIB and process the information to determine whether the SIB will be modified and in which modification period. This mitigates undesirable affects of utilizing paging to indicate SIB modification since devices read the SIB upon entering a cell, switching from active to idle mode, etc.

摘要： Described herein are mechanisms and methods that facilitate preparation of inter-radio access technology (inter-RAT) and/or inter-frequency handover with respect to a mobile device (user equipment). User equipment can indicate to a network servicing the user equipment that the user equipment desires to perform measurements with respect to a different frequency and/or different technology. Data on the downlink channel can then be scheduled to ensure that data intended for the user equipment is not lost while the user equipment is performing the measurement.
