  • Publication number: 20210360739
    Abstract: Dynamic adjustment of a network inactivity timer during user endpoint mobility states is disclosed. An example system includes a radio network including one or more base nodes, a network controller and network resources allocable to user endpoints and communications therewith. The system further including a first one of the user endpoints co-located with a vehicle and configured to determine mobility state information in correspondence with travel of the vehicle and of the first one of the user endpoints, the first one of the user endpoints utilizing an inactivity timer to release network resources allocated to the first one of the user endpoints. The network controller of the system is in communication with the first one of the user endpoints to update a value for the inactivity timer in correspondence with network policy data and the mobility state information.

  • Patent number: 10666526
    Abstract: In one embodiment, a method for estimating end-to-end accessibility in a voice over long term evolution network includes aggregating data, by a processor, from a plurality of sources in the network relating to calls originating from and terminating in the network, where the data indicates success rates for a plurality of procedures initiated by placement of the calls, and calculating, by the processor, a metric indicative of the end-to-end accessibility from the data.

  • Patent number: 10492170
    Abstract: In one example, the present disclosure describes a device, computer-readable medium, and method for paging a user endpoint device based on the mobility patterns of the individual user associated with the user endpoint device. For instance, in one example, a method includes determining a paging zone for a user endpoint device. The paging zone includes a first base station to page the user endpoint device, where the first base station is included in the paging zone based at least in part on a historical mobility pattern of the user endpoint device and on present network conditions around the user endpoint device. An instruction is sent to the first base station. The instruction instructs the first base station to send a paging request message to the user endpoint device.

  • Patent number: 9307439
    Abstract: Management of a network may be accomplished by adjusting timer settings and/or retry criteria. For example, communications and management from an end-to-end perspective of entities in a network may be conducted; timers and/or retry criteria may be adjusted dynamically based on network traffic load; timers and/or retry criteria may be adjusted dynamically based on overload conditions; feedback mechanisms may be implemented to allow downstream network elements to inform upstream network elements about the health status and/or load condition of the network; and/or differentiated timer and retry criteria/mechanisms may be implemented.
