The cooperative controlling of an operation of an application that is used by a user equipment is implemented in a wireless network by obtaining scheduled shared resource rate information and channel condition information for bearers sharing network resources. User equipment policies for the user equipment associated with the bearers can be performed based on the scheduled shared resource rate information, the channel condition information, and available video rate information in order to invoke throughput restrictions for the user equipment. The user equipment policies can be used by application functions to cooperatively control the operation of applications among a number of user equipments.

System and method for cooperatively controlling an application

The controlling of an operation of an application is implemented in a communication network by obtaining network identification and cell load information for a bearer in order to compute an actual transport block size per physical resource block (ATpP) slope for the bearer. A user equipment (UE) location corresponding to the bearer is associated with geographic pixel information in order to calculate an interference vector. The interference vector is used to compute a coverage map tuple that is used to control the operation of the application. Throughput can also be predicted using the coverage map tuple.

System and method for controlling an operation of an application

An application type of a bearer is classified by computing statistics vectors of bearer metrics and locating points on a label map corresponding to the statistics vectors to obtain application type information. The application type information is exported to a network node to control an operation of application. The bearer metrics include bearer identifier information and bearer condition information, where the bearer condition information includes channel condition information and cell congestion level information. The bearers are paired, such that uplink and downlink bearers for a same application are identified, so that paired bearers are classified together. The label map is produced using previously classified bearer information to calculate cluster centroids and cluster regions that define portions of the map for particular application types. The bearer is classified by determining which cluster region is closest to points on the label map that are associated with the statistics vectors for a particular bearer.

In a method for controlling congestion within a cell of a wireless network providing mobile HTTP adaptive streaming (HAS), a mobile HAS client in the cell delays a request for a next HAS segment of a HAS media stream for a delay time interval in response to a notification of congestion within the cell. The mobile HAS client calculates a reduced bitrate for the next HAS segment, and requests the next HAS segment at the reduced bitrate after expiration of the delay time interval. The reduced bitrate is reduced relative to a bitrate for a previous HAS segment of the HAS media stream.

Fast congestion detection is implemented in a wireless radio access network (RAN) to mitigate congestion by classifying bearers into bearer types using bearer metrics and monitoring bearers for type specific anomalies to obtain anomaly data. Congestion is detected based on the anomaly data to obtain congestion information that is exported to a network node to mitigate network congestion. Bearer metrics include radio link protocol (RLC) buffer size information, physical resource block (PRB) utilization information, and transmission burst interval information. The transmission burst interval information includes information on time intervals between successive time periods when a RLC buffer is empty. The bearers are classified into Type I and Type II bearers. Type I bearers are bearers displaying bursty data transfer behavior, and Type II bearers are bearers displaying a continuous stream of data transfer behavior.

A smoothed transport block size is forecasted by predicting future value information based on historical time series data obtained at an e-Node B. The historical time series data includes historical transport block size information and historical modulation and coding scheme information. A mapping function is used to correlate the future value information with historical transport block size information. Once the mapping function is determined, the mapping function forecasts the average transport block sizes by inputting the future value information into the mapping function. The smoothed transport block sizes and the future value information is then transmitted to an application server and/or an application client at a user equipment to control an operation of an application.

The present invention provides a method of data path switching. Embodiments of the method include transmitting a packet from a node in a communication system during hand off of a mobile node from a source access network to a target access network. The packet includes an end marker that indicates that the packet is the last packet to be transmitted during the hand off over a source link between the mobile node and an anchor node via the source access network during the hand off. Embodiments of the method also include switching, at the node, a transmission data path from the source link to a target link between the mobile node and the anchor node via the target access network following transmission of the packet including the end marker.

A method is provided for establishing a backup interface among multiple interfaces serving a mobile node, for a handover that is undetectable in advance. The invention methodology operates to cause a Foreign Agent associated with the multiple interfaces to keep a binding record of each of the multiple interfaces for which the mobile node has successfully completed the registration process. A novel Mobile IP extension is also added to facilitate the backup FA binding of the invention methodology.

The secure management of encryption keys is obtained by preventing external access thereto and ensuring that the keys do not leave an encryption unit in their original form. This result is obtained via a facility which (a) generates a unique device encryption key and at least one program encryption key, (b) encrypts the program encryption key using the device encryption key, and (c) stores the result in local memory. Thereafter, responsive to receipt of an indication to encrypt data, the program encryption key is retrieved from memory and is decrypted using the unique device encryption key. The data is then encrypted using the decrypted program encryption key and the encrypted data is stored in a server for distribution to a user who enters a request for the data. When there is a need to transport the latter key to another element, then the program key is encrypted using a symmetrical encryption key that the facility shares with the other element and the result is supplied to that element. The element then decrypts the encrypted program key using its own version of the symmetrical key.
