摘要:
Embodiments provide high reliability and responsiveness by dedicating resources both at the RAN and the core to provide high throughput, low latency communication for a critical communication service. Radio resources can be allocated to the machines in the ambulance as and where needed to guarantee the required QoS. Further, as the route an ambulance will follow to the hospital is known or can be predicted, this information is exploited by embodiments to further reduce communication delay by instantiating VNFs closer to the edge where and when they are needed. Further, end-to-end paths can be configured in advance between each access point and a hospital. In some embodiments, core network functions can be isolated from other traffic in the network so that the performance of the critical communication service is not impacted by other services. Low latency can be further enhanced by customized processing of the traffic.
摘要:
When a given user equipment (UE) has a plurality K of cells currently serving it, in various embodiments there is an algorithm for triggering the UE to wirelessly send a cell measurement report. The algorithm utilizes a parameter whose value is dependent on the number K of cells currently in the UE's active set. The UE updates K anytime a new cell is added to, or a serving cell is removed from, the UE's active set. In various examples the parameter is an offset that operates such that for adding a new cell increasing values of K make it more difficult to satisfy the algorithm. One example has the offset's value computed using a slope value provided by the network and a default offset value; another has the offset's value computed using maximum and minimum allowable values of both K and the offset which are provided by the network.
摘要:
A technique is disclosed to minimize service interruption at a wireless user equipment device during a handover by maintaining dual active connections during the handover. Upon initiating the handover, an initial/first connection with a first access node is maintained while establishing a second connection with a second access node. The user equipment device can receive data over the first connection and second connection during the handover. The first connection may be terminated (by the user equipment device or by timing out due to inactivity) after the handover is completed. Other aspects, embodiments, and features are also claimed and described.

According to various aspects, exemplary embodiments are disclosed of systems and methods related to client managed soft handover and seamless link failover for wireless networks. In an exemplary embodiment, a wireless client includes a primary interface and a secondary interface. The primary interface is configured to connect to a wireless network via a first wireless network connection. The secondary interface is configured to connect to the wireless network via a second wireless network connection. The wireless client also includes a controller configured to maintain the first wireless network connection via the primary interface and the second network connection via the secondary interface substantially simultaneously.
