Example methods, apparatus, systems, and machine-readable mediums for dynamically adjusting a network inactivity timer during user endpoint mobility states are disclosed. An exemplary 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.

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.

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.

Paging based on individual user mobility patterns

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.

A method for delivering targeted advertisement data to opt-in subscribers in an internet protocol television (IPTV) system is disclosed, the system comprising selecting an advertising target group of opt-in IPTV subscribers based on an advertiser's advertising target request; and multicasting an advertisement from an IPTV advertising server to the advertising target group. A system for performing the method is disclosed.

The present disclosure provides a system that can receive a group of channels (at least one of which includes an I-frame) from a DSL network, a memory that can store the I-frames, and a channel change detector that can detect a user's selection of a particular channel. If the memory contains the I-frame corresponding to the particular channel and if an I-frame has not been received from the DSL network, then the system provides the stored I-frame from the memory to the user.

A first data packet is sent through a system under measurement (SUM) from a sender side to a receiver side. A time distance d between the first data packet and a second data packet consecutive thereto in a packet flow is observed on the sender side. A value of d is written into a payload of the second data packet. The second data packet is sent through the SUM. The first data packet and the second data packet are received on the receiver side. A time difference D between the first data packet and the second data packet is observed on the receiver side. The value of d is extracted, at the receiver side, from the payload of the second data packet. The jitter is determined based on the value of d extracted from the payload of the second data packet and the value of the time difference D.

System and methods for creating and delivering interactive multimedia content that can dynamically adapt to at least one user. At least one user model is created for at least one user. The at least one user model represents interests and trends of the at least one user. A multimedia story is developed based on the at least one user model. A customized presentation of the multimedia story is generated. The at least one multimedia story allows for multiple presentations of the multimedia story. The customized presentation is displayed to the at least one user. The customized presentation is modified based on input from the at least one user.
