Abstract: Embodiments include systems and methods for wireless device signaling a network regarding customized ringing signal (CRS) capability and use of such information by the network. Various embodiments may receiving from the network an INVITE message notifying the wireless device of an incoming call, determining whether the INVITE message indicates that the network provides CRS service if the wireless device supports a CRS function, and including an indication in a response to the INVITE that the wireless device supports the CRS function in response to determining that the INVITE message includes an alert information header field indicating that the network provides CRS service. Various embodiments include a network computing device receiving such information and performing negotiations for CRS service with the wireless device only if the wireless device indicates CRS functional capability.

Abstract: A user equipment (UE) expedites cell reselection. In one instance, the UE startsa reselection timer for reselecting to a neighbor cell when a signal quality of a serving cell is determined to fall below a first threshold. The UE then expedites reselecting to the neighbor cell based on a difference between the signal quality of the serving cell and the signal quality of the neighbor cell when the signal quality of the serving cell falls below a second threshold.

Abstract: A configuration is disclosed to enable a UE to preempt SRVCC by triggering a handover to a Wi-Fi network. The apparatus determines whether a Wi-Fi cell is viable as a first target cell, from a plurality of target cells, serving the UE to continue the active transmission on the Wi-Fi cell. The apparatus extends a TTT timer length based at least in part on the determination that the Wi-Fi cell is viable as the target cell serving the UE to continue the active transmission on the Wi-Fi cell. The apparatus initiates a handover to the Wi-Fi cell from the first network prior to the expiration of a TTT timer and prior to the first network initiating a handover to a second target cell, from the plurality of target cells, on a second network.

Abstract: Embodiments described herein relate to managing communications for a first subscription and a second subscription of a wireless communication device, including, but not limited to, using a reduced re-order release timer having a reduced length in response to determining that a length of a tune-away interval exceeds a threshold. In some embodiments, a reduced status prohibit timer is initiated in response to determining that the length of the tune-away interval exceeds a threshold. In some embodiments, two or more status reports are transmitted during a same status prohibit timer in response to determining that transmission window occupancy exceeds a threshold.

Abstract: A method and apparatus for reducing call drop rate by validating reconfiguration messages based on service data unit (SDU) lifetime are described.A receiving device,such as a user equipment,may determine a receiving delay between receiving a first protocol data unit (PDU) and receiving a last PDU of a reconfiguration message SDU.The receiving delay may be compared with an SDU lifetime.The reconfiguration message SDU may be validated based on the comparison of the receiving delay with the SDU lifetime.A receiving delay that is greater than the SDU lifetime may indicate that the SDU is stale and,therefore,invalid.A receiving delay that is less than the SDU lifetime may indicate that the timing of the SDU is valid and the reconfiguration message SDU is to be processed.An activation time of the reconfiguration message SDU may also be honored or disregarded based on the receiving delay.

Abstract: Apparatus and methods for handover in wireless communication include attempting, by a user equipment (UE), to perform a hard handover procedure from a first cell to a second cell, where the hard handover procedure is configured for the UE by a network; determining, by the UE, that the hard handover procedure has failed; and in response to determining that the hard handover procedure has failed, attempting, by the UE, to perform a baton handover procedure from the first cell to the second cell. In some aspects, the UE may attempt to perform the baton handover procedure without first reporting to the network that the hard handover procedure has failed. The hard handover procedure may be determined as failed when the UE determines that a Fast Physical Access Channel (FPACH) is not received from the network in response to a transmission of a SYNC_UL code from the UE to the network.

Abstract translation: 用于无线通信中的切换的装置和方法包括：尝试由用户设备（UE）执行从第一小区到第二小区的硬切换过程，其中硬切换过程由网络为UE配置; 由UE确定硬切换过程失败; 并且响应于确定硬切换过程失败，由UE尝试执行从第一小区到第二小区的接力切换过程。 在一些方面，UE可以尝试执行接力切换过程，而不首先向网络报告硬切换过程已经失败。 当UE确定不响应于从UE到网络的SYNC_UL码的传输而从网络接收到快速物理接入信道（FPACH）时，硬切换过程可能被确定为失败。

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, via a first subscriber service, at least one protocol data unit (PDU) session. The UE may receive a first internet protocol (IP) address associated with the first subscriber service. The UE may register the first subscriber service with an IP multimedia subsystem (IMS) network using the first IP address. The UE may register a second subscriber service with the IMS network using a second IP address, wherein the second subscriber service uses the at least one PDU session of the first subscriber service. Numerous other aspects are described.
