Abstract: A device may receive a first session initiation protocol (SIP) message from another device, and may determine a first timestamp associated with the first SIP message. The first timestamp may represent a receipt time of the first SIP message by the device. The device may determine a second timestamp associated with a second SIP message. The second timestamp may represent a transmission time of the second SIP message by the device, and may be a response to the first SIP message. The device may determine a device latency value representing a difference between the second timestamp and the first timestamp. The device may provide the second SIP message to the other device at the transmission time. The second SIP message may include the device latency value.

Abstract: A system described herein may provide a technique for handling call requests, prior to the performance of a call setup procedure, based on attributes of a calling User Equipment (“UE”) and/or a called UE. A Messaging Application Server may receive a call request, from the calling UE and to the called UE, identify a category or event type associated with the call request, and notify the called UE of the call request, including the category or event type. Different categories or event types may be associated with different sets of eligible actions to perform. The called UE may indicate a particular action, associated with the identified category or event type, and the MAS may handle the call request according to the particular action (e.g., reject the call request or proceed with a call setup procedure).

Abstract: A network node receives a registration message, where the registration message is associated with registering a user equipment (UE) with a call signaling network for sending or receiving calls. The network node receives a notification message from a call session control node in the call signaling network, where the notification message indicates whether the UE is currently provisioned to engage in calls via a Voice over Long Term Evolution (VoLTE) network. The network node causes calls to or from the UE to be routed via the VoLTE network if the notification message indicates that the UE is currently provisioned to engage in calls via the VoLTE network, and causes calls to or from the UE to be routed via a legacy network, that is different than the VoLTE network, if the notification message indicates that the UE is currently not provisioned to engage in calls via the VoLTE network.

Abstract translation: 网络节点接收注册消息，其中注册消息与向用户设备（UE）注册用于发送或接收呼叫的呼叫信令网络相关联。 网络节点从呼叫信令网络中的呼叫会话控制节点接收通知消息，其中通知消息指示UE当前是否被配置为经由长期演进语音（VoLTE）网络进行呼叫。 如果通知消息指示UE当前被配置为经由VoLTE网络进行呼叫，则网络节点通过VoLTE网络来呼叫或从UE进行呼叫，并且使来自UE的呼叫经由 如果通知消息指示UE当前未被配置为经由VoLTE网络进行呼叫，那么与VoLTE网络不同的传统网络。
