    摘要： Broadcast control messages are repetitively transmitted to said mobile stations over successive control channel cycles to meet minimum recommended periodicity requirements. To increase paging capacity, the frequency of one or more of the broadcast control messages may be varied to avoid unfavorable pairings of the broadcast control messages within a single control channel cycle.

    摘要： Call setup latency for a packet data call dormant reactivation is reduced by bypassing service negotiation and/or RLP Sync exchange procedures using values stored at the BSC. Previously negotiated parameters may be used to bypass service negotiation. A non-zero RTT value, calculated by a previously performed RLP Sync exchange, is stored at the BSC, and transmitted to the MS upon dormant reactivation. The MS uses the RTT to calculate a RLP REXMIT_TIMER value, bypassing a RLP Sync exchange with the BSC. The service configuration parameters and non-zero RTT may be stored at the BSC in the RLP BLOB of a SCR, which may be transmitted to the MS in an SCM. The SCR may store multiple records, each containing negotiated service configuration parameters and/or a non-zero RTT associated with a service instance, selected by a SRID transmitted by the MS.

    摘要翻译： 通过使用存储在BSC中的值绕过服务协商和/或RLP Sync交换过程来减少分组数据呼叫休眠重新激活的呼叫建立延迟。 以前协商的参数可用于绕过服务协商。 由先前执行的RLP Sync交换计算的非零RTT值存储在BSC中，并且在休眠重新激活时被发送到MS。 MS使用RTT来计算RLP REXMIT_TIMER值，绕过与BSC的RLP Sync交换。 服务配置参数和非零RTT可以存储在SCR的RLP BLOB中的BSC处，其可以以SCM发送到MS。 SCR可以存储由MS发送的SRID选择的多个记录，每个记录包含协商的服务配置参数和/或与服务实例相关联的非零RTT。

    摘要： In mobile user equipment (UE) configured to allow for operation on multiple wireless communication networks, such as on a TD-SCDMA network or on a TDD-LTE network, an improved method for handing over a circuit-switched call is offered. The proposed circuit-switched fallback procedure, employing an improved UE hardware architecture, allows for certain connection setup procedures to occur in parallel, such as the UE pre-acquiring the TD-SCDMA cell. The parallel operations thus speed up the circuit-switched fallback procedure and reduce existing delays in executing circuit-switched fallback from TDD-LTE to TD-SCDMA networks.

    摘要： A cross-layer optimization is presented between the MAC and Network layers to enhance the performance of VoIP services in advanced wireless networks. Among the factors considered in the optimization are the characteristics of the originating source and the network path. This information is relayed using the Network layer to provide feedback to the MAC layer in order to improve the end-to-end performance of VoIP services.

    摘要： In a method for multicast and broadcast synchronization a data payload frame is generated from a data payload. A frame number is assigned to the data payload frame, wherein the frame number includes a generating time of the data payload frame. The data payload frame is distributed to a plurality of base stations in a wireless access system. The offset spans a travel time of a data payload frame from the controller to the plurality of base stations as well as a scheduling time and a multiplexing time.
