20090067372 | HOST-BASED QUALITY OF SERVICE FOR WIRELESS COMMUNICATIONS - Systems and methodologies are described that facilitate providing quality of service (QOS) functionality on a host device or tethered processor to conserve resources on a network device. In particular, the host device/tethered processor can classify QOS data and manage QOS flows, transmitting data by flow to the network device. The data from the QOS flows can be tagged to identify the flow and/or characteristics thereof allowing the wireless device to simply route the data to its respective flow. Thus, the network device is saved from such classification and flow management freeing resources to provide increased performance and decreased power consumption. | 03-12-2009 |
20090069018 | METHOD FOR SUPPORTING MULTIPLE DIVERSIFIED DATA APPLICATIONS WITH EFFICIENT USE OF NETWORK RESOURCES - To enable applications to share an established data connection, communication configuration parameters identified by a new application are compared to the parameters requested by applications already sharing the data connection. If there are no conflicts with exclusive configuration parameter(s) required by a new application, a union rule is applied to each shareable configuration parameter of the new and currently executing applications using the data connection to determine a mutually acceptable configuration. Also determined is a measure of the degree to which all applications are supported by a compromise parameter determined by the union rule. The data connection best supporting the sharable parameters of the new and executing applications is assigned to the new application. When an application terminates, the union rules may be applied to parameters requested by the remaining applications to reconfigure the data connection. A similar process may be used when an application requests changes to configuration parameters. | 03-12-2009 |
20090119773 | APPARATUS AND METHODS OF CONFIGURABLE SYSTEM EVENT AND RESOURCE ARBITRATION MANAGEMENT - Methods, apparatus, and computer-readable media for management and arbitration of dedicated mobile communication resources for mobile applications are provided. Mobile applications can be given a priority level that establishes an importance with respect to one or more other mobile applications and at least one mobile resource. If competing applications attempt to access the mobile resource concurrently, access can be provided to an application having higher priority level. Furthermore, control of a resource can be taken away from an application having lower priority in order to affect control of such resource for a higher priority application. In one aspect, a privilege code of an application can be verified prior to establishing control of the resource for the application, to mitigate a likelihood of inappropriate transfer of resources. Accordingly, the subject disclosure provides for management of dedicated resources for a mobile processing environment to effect important device functions with minimum delay. | 05-07-2009 |
20090144819 | FLOW CLASSIFICATION FOR ENCRYPTED AND TUNNELED PACKET STREAMS - Methods and systems for solving the problem of special processing required by various communication network subsystems (e.g., QOS, security, tunneling, etc). In some cases the processing by one communication subsystem may result in modified IP data packets which may affect the application of additional processing of such packets. The methods and systems solve problem by translating filters and setting up additional tunnels or other procedures based on the use case so that all the end and intermediate nodes can do the required processing on modified packets. The methods and systems may take into consideration an overlap or intersection of two or more different types of packet filters. A first set of packet filters is translated to provide the desired packet classification for modified packets. The second set of packet filters may be translated based upon the translation applied to the first set of packet filters. | 06-04-2009 |
