摘要:
An intermediary function receives a reservation request for a desired throughput from the sourcing device, and determines a set of bearers whose aggregate throughput approximates the desired throughput. The intermediary function requests from at least one access network the set of bearers whose aggregate throughput approximates the desired throughput, and receives from the at least one access network an allocated set of bearers, wherein the allocated set of bearers comprises one or more bearers. The intermediary function informs the sourcing device of an aggregate throughput of the allocated set of bearers, receives user plane data from the sourcing device, and associates the user plane data with the allocated set of bearers in order to transport the user plane data to the receiving device. Subsequent modifications to the allocated set of bearers causes the intermediary function to inform the sourcing device of the modified aggregate throughput of the allocated set of bearers.

A method and apparatus distributes video packets over multiple bearers for providing unequal packet loss protection. The method includes a packet processing function receiving a plurality of packets collectively comprising a flow of sequential data included in a sequence of media frames. For each packet, the packet processing function: applies a bearer selection process to select one of a plurality of bearers for transporting the packet over an access network, wherein each bearer has a different quality of service level which influences the probability of the transported packets being intentionally discarded by the access network, wherein the bearer selection process causes distribution of the plurality of packets across the plurality of bearers such that each bearer carries non-consecutive packets both within any given media frame and across sequential media frames and provides unequal packet loss protection for the packets in the plurality; and provides an indication of the selected bearer.

A method and apparatus distributes video packets over multiple bearers for providing unequal packet loss protection. The method includes receiving a plurality of packets that collectively includes video data from a group of pictures comprising a sequence of video frames, wherein the sequence includes one Intra frame at the beginning of the group of pictures followed by a plurality of Predictive frames. For each packet, the packet processing function: determines the corresponding frame that includes the video data; applies a bearer selection process to select one of multiple bearers for transporting the packet over an access network, wherein each bearer has a different quality of service level which influences the probability of the transported packets being dropped, wherein the bearer selection process is based on the position of the frame within the sequence of frames; and provides, to an access network entity, an indication of the selected bearer.

A method for bearer reservation, maintenance, and use in a communication system is performed by an intermediary function (IF) in the enterprise network. The IF processes a user plane reservation request for a flow of user plane data from a sourcing device, and determines a set of bearers to transport the flow of user plane data. The IF requests from at least one access network the determined set of bearers, and receives from the at least one access network an allocated set of bearers, wherein the allocated set of bearers comprises one or more bearers. The IF receives the flow of user plane data from the sourcing device. The IF receives an indication that at least one of the bearers in the allocated set of bearers is unavailable, and prevents at least a portion of the flow of user plane data from being transmitted over the default bearer.

A method and apparatus for granting wireless connection resources for a UE within a communication system is provided herein. During operation, an application requests allocation of wireless communication resources (a bearer reservation) to sustain transmission at a specified bit rate across the communication system via an admission control function. In response to the bearer reservation request, an admission control function calculates a wireless connection efficiency as a function of the requested bit rate and an amount of shared wireless connection resources required to sustain the requested bit rate given the current wireless connection quality associated with the UE. The wireless connection efficiency is then utilized to determine whether or not to admit the bearer reservation request.

Analytic and tracking systems and methods are described that use over-the-air identifiers (OTAIs) of mobile devices for tracking, dispatch, identification, etc. In particular, the analytic and tracking systems and methods can include various OTAI sensors that are communicatively coupled to a server and with one another. The OTAI sensors are configured to identify proximate mobile devices concurrent with at least one additional piece of information. The analytic and tracking systems and methods can process identified mobile devices and the additional pieces of information for a plurality of applications.

A method, apparatus, and system for performing facial recognition utilizing large databases is provided herein. During operation a large database is quickly narrowed by determining an automobile attribute (e.g., a license plate number) and determining a registered owner and possibly an address based on the automobile attribute. The image database is narrowed based on the registered owner of the vehicle, and possibly the address of the registered owner.

A route correlation method, an identification method, and a route correlation system determine an implicit relationship between two entities, i.e. two users with mobile devices, following dynamic, but similar paths or routes, but which otherwise lack an explicit relationship. Through this implicit relationship, the identity of one entity can be known to another. The route correlation method includes determining a route for a first mobile device, determining a route for each of a plurality of mobile devices, correlating the route for each of the plurality of mobile devices with the route for the first mobile device, identifying each of the plurality of mobile devices with their associated routes matching the route of the first mobile device, and associating each mobile device with an entity.

A method and apparatus for identifying a suspect through location and time events is provided herein. During operation a central server continuously receives updates from multiple networks regarding device identifiers and associated access points. When an event (e.g., a crime) occurs at a certain location, an access point(s) near the event are identified and devices associated with the access point(s) at the time of the event are determined. The identified devices are then utilized to determine potential suspects.
摘要:
A service request (150) having a predefined QoS (152) can be received from an end-user device (105) by a transit device (110). The transit device (110) can act as an access point for the end-user device (105) to connect to a mobile broadband network (135). A transport resource (130) of the transit device (110) can be allocated to handle a data flow of the received service request (150). The network address of the allocated transport resource (130) can be recognized by the mobile broadband network (135). The network addresses associated with data packets (160) of each data flow supporting the service request (150) can be translated by the transit device (110). The translation can occur between the network address of the end-user device (105) and the network address of the transport resource (130) allocated to the data flow based upon a directionality of the data packets (160).
